The invention has the advantages that: when the closing device for the ship body anchor hole outer plate opening is used for retracting the ship anchor, the working process is as follows:

as shown in fig. 1, 4 and 5, in the ship anchor storage state shown in fig. 1, at this time, the rolling device applies a pulling force to the ship anchor through the anchor chain, so that the ship anchor drives the protruding rod 13 to apply a pressure to the first spring 15 through the anchor cylinder 18, so that the first spring 15 obtains a downward restoring force, and at this time, the outer plate 30 closes the opening of the anchor hole, when the ship anchor needs to be put down, the rolling device 3 releases the anchor chain, so that the ship anchor has no upward pushing force to the anchor cylinder 18, so that the protruding rod 13 drives the anchor cylinder 18 to move down under the restoring force of the first spring 15, the downward movement of the protruding rod 13 drives the piston plate one 21 to apply a pressure to the oil in the cylinder barrel one 22 through the first sliding rod 19, so that the oil is delivered into the cylinder barrel two 25 from the liquid pipe four 23, and the oil applies a pushing force to the sliding rod two sliding rod 26 through the piston plate two 24, so that the sliding rod two sliding rod 26 drives the outer plate 30 to rotate around the rotation center of the hinge shaft 12 through the connecting rod 27 and the arc rod 28, the opening part of anchor cave is not blocked, thereby realize that drive planking 30 is automatic to be opened when releasing the ship anchor, so that the smooth and easy of ship anchor puts down, as shown in figure 4, at the in-process that the ship anchor was transferred from the opening part of anchor cave, because the effect of spring 15 makes the anchor chain be in the tensioning state, just so rock at the in-process of transferring in the anchor cave through anchor barrel 18 restriction ship anchor, thereby avoid the card to lead to the ship anchor can not normally put down and cause the accident in the anchor cave, and after planking 30 is opened in the rotation downwards, make backplate 29 towards the direction of ship anchor, can avoid rocking of ship anchor to lead to the striking damage to the hull when packing up the ship anchor like this.

In the process of retracting the ship anchor, the winding device 3 winds up the ship anchor through the winding anchor chain, and in the process of moving the ship anchor to the anchor cylinder 18, through the shielding of the protective plate 29, the ship anchor is prevented from shaking in the process of retracting to cause impact damage to the ship body, the ship body is protected, the practical service life of the ship body is prolonged, after the anchor rod of the ship anchor enters the channel 17, no matter the fluke of the ship anchor faces any direction, the fluke can be stably clamped in the annular groove 20, the ship anchor is stabilized, the problem that the fluke shakes in the fluke to cause collision and clamping is avoided, the normal use of the ship anchor is ensured, when the winding device 3 drives the ship anchor to continuously move upwards through the anchor chain and reset, the ship anchor applies upward thrust to the anchor cylinder 18, the convex rod 13 is driven to move upwards through the anchor cylinder 18, meanwhile, pressure is applied to the first spring 15, and the first spring 15 obtains downward restoring force and resets, and the convex rod 13 moves upwards through the first sliding rod 19 to drive the first piston plate 21 to move upwards, and the oil in the second cylinder barrel 25 is pumped into the first cylinder barrel 22 through the fourth liquid pipe 23, so that the second piston plate 24 exerts a pulling force on the connecting rod 27 through the second sliding rod 26, the connecting rod 27 drives the outer plate 30 to rotate upwards around the hinge shaft 12 through the arc-shaped rod 28, and the open end of the anchor hole is blocked, the open end of the anchor hole is blocked by the outer plate 30 when the ship anchor is stored, seawater is prevented from entering the inside of the anchor hole in the sailing process of the ship body, sailing of the ship body is not affected, meanwhile, the outer plate 30 blocks the open end of the anchor hole, the ship body is more attractive, parts in the anchor hole are protected from being corroded by impact of seawater, and the service life is prolonged.

As shown in fig. 1, 2, 3 and 4, when the temperature is low, so that the outer plate 30 is frozen, or the rotation part of the hinge 12 is not lubricated enough, and the resistance is high, the hydraulic pump 2 is started to operate, and the electromagnetic valve 6 is closed, at this time, the hydraulic pump 2 pumps out the hydraulic oil in the hydraulic oil tank 1 through the first liquid pipe 4 and delivers the hydraulic oil to the third liquid pipe 8 through the fifth liquid pipe 32, and when the hydraulic oil flows through the fifth liquid pipe 32, the impeller 43 drives the turntable 33 to rotate, so that the pin rod 34 drives the sliding cylinder 42 to slide up and down in the collar 39 through the deflector rod 35, and further the sliding cylinder 42 drives the hammer rod 40 to continuously hammer the outer plate 30 through the second spring 41, so as to shake off the ice on the outer plate 30, and ensure that the outer plate 30 can be opened smoothly, the third liquid pipe 8 delivers the hydraulic oil to the hydraulic cylinder 9, so that the hydraulic cylinder 9 drives the anchor cylinder 18 to move down in cooperation with the downward restoring force of the first spring 15, and then make the ship anchor transfer smoothly to improve the ability to deal with extreme weather, wherein closing of solenoid valve 6 avoids passing through two 5 pressure release in the liquid pipe when carrying hydraulic drive power to pneumatic cylinder 9, and when not starting hydraulic pump 2, solenoid valve 6 is in the on-state, plays the effect to pneumatic cylinder 9 pressure release, ensures that pneumatic cylinder 9 does not interfere reciprocating of nose bar 13, thereby ensures going on smoothly of ship anchor receive and release process.
