Background
Dream of floating on water
The lyrics of a sentence in the swordsman drama book are written as follows: ever, the dream of walking on the sky with the sword and floating on water with light power.
People always dreams and try to walk on the water surface easily and freely by various methods like walking on the land.
The key of walking on water lies in the stress balance, so that at present, there are two schemes
-scheme a: the density of water is increased, a lake is called as dead sea, the density is higher than the density of a human body, and a person can lie on the surface of the lake.
-scheme B: run, run at speed, run at top speed. How fast this speed is? The first cosmic velocity is 7.9 km/s.
Second, problem proposition
One lake is called dead sea, the density of which is greater than that of a human body, and people can lie on the surface of the lake. However, no natural person standing in an upright state can stand on the lake surface. The main reasons considered by the pen are as follows:
pressure formula: p is F/S; wherein P denotes pressure, F denotes positive pressure, and S denotes contact area
P single foot/P lying 30000Pa/1000Pa 30 (times)
P feet/P lying ═ 15000Pa/1000Pa ═ 15 (times)
That is, the pressure to the ground when a person stands upright and lands on the ground with one foot is approximately 30 times larger than that of a lying person with the same weight,
the pressure on the ground when a person stands upright and the feet land is 15 times larger than that of a lying person with the same weight.
And (3) knotting: the natural people with the same weight characteristic have different results because of different states and different pressure intensity on the horizontal plane. This is a physical phenomenon.
Third, the method to solve
For the same reason, the example that both feet of the standing person contact the horizontal plane is taken now
When a person lies flat, the pressure is similar to that on a horizontal plane of every square decimeter, only 1 object can be placed at most, and the object can float on the water surface or in the water without sinking.
When the person stands, the pressure is similar to that of a horizontal plane per square centimeter, 15 same objects are placed, but in order to enable the objects to float on the water surface or in the water without sinking, four methods of reducing the total gravity center, reducing the total density, increasing the contact area with the water and improving the drift speed on the water are adopted, and the goal can be achieved.
In short, the implementation scheme (3) of the design scheme of the water drifting of the standing man is a scheme of walking on the water by standing on the water surface or in the water by using the principles of buoyancy and tension of the water and selecting a proper natural man in a standing state. The concrete method is as follows
(one) lowering the total center of gravity and increasing stability
According to the dynamic balance principle of a tumbler, an upright person is designed to stand on a horizontal plane, the center of gravity of the whole upright person is low, and therefore the upright person is not easy to fall down and fall into water in the drifting process.
The method is to increase the inflation device at a proper position, the upper part is light and the lower part is heavy, and the contact area between the inflation device and the horizontal plane is enlarged as much as possible.
(II) enlarging the contact surface and increasing the stability
Brief introduction to the method of increasing contact area with horizontal plane
When the device is not equipped, the left and right soles of the human body are contacted with the water surface.
After wearing the equipment of the design, the four flippers and the tail are contacted with the water surface.
The contact surface between the left and right flippers and water is initially 2 times larger than the original two flippers, and also has contact surface between the third and fourth inflated flippers and 5 tails.
(III) adding an air charging device and reducing the total density
The design method comprises the following steps: and (3) selecting a proper upright person, wearing all the additional inflatable devices of the design, and standing in the water to perform drifting.
Suitable person standing upright
For the purpose of reducing the overall density of people standing on the water surface or in the water, our requirements for a suitable standing person are: the smaller the weight, the better the body height, the higher the body height, the better the upright person of the slim body type with a certain self-control ability.
Thus, when the hollow equipment with the same volume is worn, the density reduction is larger, the suitable upright people according to the requirements are originally determined to be upright people with the weight not more than 20 kg, and the ordinary natural people who can independently walk and have self-control ability are not less than 6 years old.
Externally-applied inflating device
A suitable upright person wears an inflatable buoyancy waistcoat with a tail (4), two inflatable arm circle diagrams (5) and an inflatable wrist bracelet chart (6) respectively on the left and right, the left and right hands hold a handle diagram (7) above a third inflatable foot and a fourth inflatable foot like supporting two walking sticks, and the total density of the person is reduced due to the addition of the inflatable devices.
(IV) increasing the speed and improving the stability
The design has two styles of manual style and electric style.
The electric money is much more stable than the manual money because the drift speed is much faster than the manual money. The preferred recording is carried out according to specific conditions.
And (3) knotting: when the device is worn, the total density of the contact surface of the device and the horizontal plane is lower than that of water, so that a person standing in the water can freely walk on the water surface like walking on the land instead of sinking in the water.
According to the buoyancy principle, the total density of the standing person is less than that of water, so that the standing person can walk in water like a ship.
According to the principle of tension, when the total downward pressure of the contact surface of the person standing upright with the horizontal plane is less than the maximum pressure corresponding to the tension of water, the person can walk on the water surface at a certain speed and easily without damaging the tension of water like a water strider. .
Third, additional equipment
The additional equipment of this design mainly includes: (1) a tail-equipped inflatable buoyancy waistcoat diagram (4); (2) an inflation arm circle diagram (5); (3) an inflatable wrist bracelet chart (6); (4) a third electrically powered pneumatic foot; (5) a fourth electrically powered pneumatic foot; (6) a handle schematic diagram (7) with buttons; (7) damper diagram (8); (8) an electric cylindrical cam or an electric paddle (14); (9) a reverse-wearing flipper map (12) with a water-scraping scoop ditch; (10) a plurality of wires.
The design has two styles, manual style and automatic style. When the standing person presses the button, the button switch on the handle is formed by the two handles on the third inflatable flipper and the fourth inflatable flipper; pressing the money file is either a manual money file or an automatic money file.
Fourth, method for floating on water
Considering the maximum water grabbing force of the four flippers, the four flippers are used as flippers for digging the water spoon groove by the flippers with the shape similar to that of a water duck on the instep and the shape of the concave groove in the shape of a spoon which is concave inwards on the bottom.
In order to reduce the resistance of water, the four flipper positions are designed such that the front is the heel with a small area and the rear is the toes with a large area, which we simply describe as passing the flipper backwards. In conclusion, the flippers in the manual state and the automatic state are reverse-wearing flippers with a scupper ditch (12).
This design has two kinds of styles of automatic money and manual money, switches through the button switch on the handle.
Automatic money drifting method
The prime mover is the third and fourth electrically inflatable legs.
(1) Electric cylindrical cam drift
The thumb presses a button switch near the handle, the third and the fourth electric air charges and reversely penetrates the flippers to start to stroke up and down, then drives the left and right reversely penetrates the flippers and the tail to drag the flippers and the tail to drift on (or in) the water surface.
(2) Electric paddle drift
The thumb presses a button switch near the handle, the third and the fourth electric air charges reversely through the flippers to start to stroke by rotating, and then drives the left and the right reversely through the flippers and the tail to drag the water surface (or the middle) to drift.
(II) Manual money drifting method
The appearance structure is the same as the automatic money, and only the electric button on the handle is not opened.
(1) The left and right flippers are prime power
The thumb is not pressed a button switch near the handle and is in a manual state. The left and right flippers stroke up and down, and then the third and fourth flippers and the tail are driven to drag on the water surface (or in the middle) to drift.
(2) The third and fourth flippers as prime power
The thumb is not pressed a button switch near the handle and is in a manual state. The third and the fourth flippers stroke up and down, and then the left and the right flippers and the tail are driven to drag on the water surface (or in the middle) to drift.
The above four drift methods are the most preferred, the first one. The electric paddle with the accelerated speed is used for paddling, so that four pieces of anti-wearing flippers and a tail with an extended inflatable buoyancy waistcoat are always in contact with the horizontal plane to enlarge the contact surface.
In the other three methods, the alternate up-down stroke method of raising and lowering two of the four flippers at the same point is adopted, so that the contact area is reduced and the effect is not good enough compared with the first method.
The design scheme is simple and easy to operate, has certain utility model characteristics, and is suitable for water sports projects of entertainment and sports.

Seventhly, knowing: the contact area of each foot and the ground is 0.02 square meter
The invention content is as follows:
first, theoretical basis
Concept of drift
The differences between floating and floating are:
the drift is typically wind related, such as flying with the wind.
The float is generally water-related, meaning that it stays at the surface of the liquid without sinking, e.g. leaves float on the surface of the water.
The floating and sinking of the object in the liquid are carried out in five states of floating, sinking, suspending, floating and sinking.
Floating refers to the situation where the buoyancy of a solid or liquid in a gas is not less than gravity. When a part of the solid is exposed to the surface, the solid is balanced by buoyancy and gravity, and the phenomenon is called floating.
The solid is completely immersed in liquid or gas, and the buoyancy and the gravity are balanced, so that the suspension is called. The floating refers to the situation of solid or liquid in gas, including the suspension situation.
In general, floating refers to a state where an object is subjected to buoyancy and gravity equilibrium at the surface of a liquid and does not sink. An object in a floating state moves in a certain direction, referred to as drift.
A design scheme for the water drift of a standing person refers to a water sport item in which the standing person floats on the water surface or in water to float and move on the water.
Ratio of (two) pressures
The ratio of the pressure intensity of the standing state and the pressure intensity of the lying state of the same person to the horizontal plane is 15-30 times, which is the principle that no standing person stands in the salt river sea water.
The pressure intensity of the pressure intensity is different from that of the pressure intensity of.
The drawing pin mainly comprises a drawing pin cap and a drawing pin tip. When the thumb presses the picture nail cap against the pine, the picture nail tip can be pressed into the pine by only applying a little force.
On the contrary, when the finger presses the pin tip with the same force, the pin cap cannot be pressed into the pine.
In other words, our lying position has better contact surface against the water surface than the pushpin cap against the pine. The pressure intensity is small, and the contact surface is large; and the contact surface of the upright state to the water surface is opposite to the pine like the pointed end of a nail head. The pressure intensity becomes larger and the contact surface becomes smaller.
In short, people who float on the river and sea in a lying state can walk on standing water surface in an upright state due to different pressure intensity and the like.
Second, implementation method
The method for realizing the floating of the standing person on water mainly comprises four methods
(one) lowering the center of gravity and increasing stability
And the tumbler has the smallest distance between the gravity center and the contact point when the tumbler is in a balance state in a vertical state, namely the gravity center is the lowest.
According to the principle, the total gravity center of the upright person wearing the auxiliary equipment is lower as much as possible, the stability is improved, and the upright person is not easy to fall into water when walking on the water surface.
(2) Increasing total volume to make total density less than water density
The design scheme requires that the weight of an upright person is not more than 20 kg, namely, the upright person is a suitable ordinary person with light weight and high height. After the inflatable equipment is worn, the total density ratio is obviously reduced compared with that before the inflatable equipment is worn, so that the aim that the total density of a human body is smaller than the water density is fulfilled.
The ordinary person who is fit refers to a natural person who has a certain self-control ability and can walk. According to the requirements, children of 6 to 8 years old or ordinary people capable of achieving the purpose that the total density of the human body is less than the density of water can try the water entertainment event.
The self-control ability of natural people less than 6 years old and the weight of the natural people too large are not good enough, and after the air inflation equipment is worn, the total density is not obviously reduced, and the target requirement cannot be met.
Theoretically, when the total density of the contact surface of the equipment and the horizontal plane is lower than that of water when people wear the equipment, a person standing in the water can freely walk on the water surface like walking on the land instead of sinking in the water.
When the device is worn, the total downward pressure on the contact surface of the device and the horizontal plane is less than the maximum pressure corresponding to the tension of water, so that the device can walk on the water surface without damaging the tension of water like a water strider.
(3) Increase the contact area with water and stability
The ratio of the density of water to the density of air is 773.395205 (times)
(1000:1.293=773.395205)。
When the standing person stands on the water surface originally, the contact surface of the standing person and the water surface is the sole surface of two feet.
When a standing person stands on the water surface, the contact surfaces of the standing person and the water surface are (1) the reverse wearing fin surfaces of the left foot and the right foot (2), and the two hands are inflated with air through the damping springs and the hard feet to become the reverse wearing fin surfaces (3) of the third foot and the fourth foot, and the inflated waistcoat with the tails drags one to five tails off the water surface.
(4) Increasing drift velocity
The floating of the walking device on water has two types, namely an automatic type and a manual type, namely automatic sliding and manual walking. Automatic money is more stable than manual money.
Third, additional equipment structure and function
(I) additional equipment structure
An external device of a design scheme for the water drift of a standing person mainly comprises (1) an inflatable buoyancy waistcoat with a tail (2) and two inflatable arm rings in total, wherein the inflatable buoyancy waistcoat is arranged at the left and the right respectively; (3) one for each left and right, two inflatable wrist bracelets in total; (4) one on the left and the right, two feet on the left and the right respectively; (5) the left hand and the right hand are respectively provided with one, two in total, namely the left hand and the right hand are extended to form a third electric inflation foot and a fourth electric inflation foot and a plurality of electric wires for reversely penetrating the flippers (6).
(II) additional equipment structure function
(1) The spring damper device has a structure that disperses force and cushions downward pressure of the arm gripping the handle.
(2) The flipper is worn reversely, the appearance structure of the flipper, the appearance of the instep is similar to the flipper of the water duck, and the appearance of the bottom is a concave groove which is concave inwards and is similar to the shape of a spoon, so that the paddling force is increased. The reversed wearing of the flipper has the function of reducing pressure.
The function of the flipper for scooping water backwards is that the standing person can walk forwards after scooping water backwards according to the principle of acting force and reacting force.
(3) Increase volume and reduce density
An inflatable buoyant vest with a tail; the two hands are sleeved with an inflatable bracelet; the inflatable water sleeve has the functions of increasing volume and reducing density.
(4) Four anti-wear flippers and an inflatable buoyancy waistcoat extending tail with function of enlarging contact surface
(5) The electric gear for increasing the speed floats on the horizontal surface more stably than the manual gear,
the third and fourth inflatable feet similar to the left and right crutches and the electric rowing device contained therein are briefly described as follows
Mainly comprises a handle with a button, a damping device, an electric paddling device, a hard plastic inflatable foot shell and the like.
When a button switch on the handle is pressed, the third and fourth inflation feet are in an electric state.
The third and fourth inflation legs are manually actuated when the push button switch on the handle is released.
(6) Two electric paddling device
The electric cylindrical cam converts the rotary motion into the linear motion cylindrical cam, thereby driving the flippers to scoop water backwards alternately from top to bottom, and the upright person can walk forwards on water according to the principle of acting force and reacting force.
The electric paddle is just like the electric paddle for ordinary rowing, and four tails extending from the flipper and the inflatable buoyancy waistcoat are always floated on the water surface or in the water for fast forward sliding.
Method for drifting
A design scheme for the floating of a standing person on water is characterized in that the person wears an inflatable buoyancy waistcoat with a tail, the left foot and the right foot are respectively sleeved in a reverse wearing fin, and the left hand and the right hand are respectively pressed on handles of the inflatable feet like a crutch. The handle is provided with a button switch near the thumb, which is used as a switching button for controlling an automatic gear and a manual money. Two styles, automated and manual, are summarized as follows:
automatic money drift

(1) Electric cylindrical cam drift
(2) Electric paddle drift
(II) Manual money drifting
The appearance structure is the same as the automatic money, and only the electric button on the handle is not opened.
(1) The left and right flippers are prime power
(2) The third and fourth flippers as prime power
The thumb is not pressed a button switch near the handle and is in a manual state. The third and the fourth flippers stroke up and down, and then the left and the right flippers and the tail are driven to drag on the water surface (or in the middle) to drift.
The above four drift methods are the most preferred, the first one. The electric paddle with the accelerated speed is used for paddling, so that four pieces of anti-wearing flippers and a tail with an extended inflatable buoyancy waistcoat are always in contact with the horizontal plane to enlarge the contact surface.
In the other three methods, the alternate up-down stroke method of raising and lowering two of the four flippers at the same point is adopted, so that the contact area is reduced and the effect is not good enough compared with the first method.
In short, a design scheme for floating of a standing person on water is that the standing person can easily and freely walk on the water surface (or float in water, and are part of the lower part of the foot instead of being completely immersed in water) by wearing the equipment of the design.

(Baidu encyclopedia): floating on the ground
Floating refers to the situation where the buoyancy of a solid or liquid in a gas is not less than gravity. When a part of the solid is exposed to the surface, the solid is balanced by buoyancy and gravity, and the phenomenon is called floating (note the difference between floating and floating). The solid is completely immersed in liquid or gas, and the buoyancy and the gravity are balanced, so that the suspension is called. Floating, in turn, refers to the situation where a solid or liquid is in a gas, including a suspension.

Sixthly, knowing: a person lies flat on the bed, and the pressure to the bed surface is closest to 1000Pa
Assuming a human mass of 60kg, the width of the contact surface with the bed is 0.35m and the length is 1.7 m.
So the pressure F is 600N, the contact area S is 0.35 multiplied by 1.7m 2 is 0.6m 2
The pressure P is 600/0.6 Pa/600 Pa
Seventhly, knowing: the contact area of each foot and the ground is 0.02 square meter

Pressure of the person on the ground: g60 kgx10N/kg 600N
Two feet touch the ground: when he stands on the ground, the pressure of the foot on the ground: p feet F/S1 600N/0.04 square meter 15000Pa
One foot is grounded: when he is walking normally, the pressure alone to the ground:
F/S2 600N/0.02 sq.m 30000Pa
P single foot/P lying 30000Pa/1000Pa 30 (times)
Two feet touch the ground: when he is walking normally, the pressure of the feet against the ground:
p feet/P lying ═ 15000Pa/1000Pa ═ 15 (times)
That is, the pressure to the ground when a person stands upright and lands on the ground with one foot is approximately 30 times larger than that of a lying person with the same weight,
the pressure on the ground when a person stands upright and lands on the ground with two feet is approximately 15 times greater than that of a lying person with the same weight.
