As shown in fig. 1, the underwater glider with movable horizontal wings provided by the preferred embodiment of the present invention comprises a glider main body 1, horizontal wings 2, a slideway 3 and a sliding rod 4, wherein the slideway 3 is fixed on the glider main body 1 and is parallel to the central line of the glider main body 1; the slide bar 4 is mounted on the slideway 3 in a longitudinally movable manner, and the horizontal wing 2 is fixed on the slide bar 4. Therefore, the underwater glider provided by the embodiment of the invention has the advantages that the original fixed horizontal wings are designed into a structural form capable of moving longitudinally, and the adjustment of the gliding motion angle of the underwater glider can be realized by changing the longitudinal position of the horizontal wings 2 on the glider main body 1 in the process of gliding motion of the underwater glider, so that the problem that the gliding angle is influenced by hydrodynamic force on the traditional solid horizontal wings is effectively solved, the method that the existing underwater glider adjusts the gliding motion pitch angle by adopting the longitudinal movement of the mass block is replaced, the internal control structure of the underwater glider is greatly simplified, and the impact resistance of the whole machine is improved; moreover, under the condition that a mass block control device exists inside the underwater glider, the longitudinally moving horizontal wing device provided by the invention can be additionally arranged, so that the requirement of the mass block on control moment is reduced, and the control effect is improved.

Illustratively, the underwater glider with movable horizontal wings further comprises a mechanical fixing structure for fixing the longitudinal position of the horizontal wing 2, such as: the fastener, the bolt, the pin and other detachable fixed components facilitate the positioning and adjustment of the horizontal wing before the underwater glider is thrown in.

Illustratively, as shown in fig. 1, the underwater glider with movable horizontal wings further comprises a horizontal wing driving module 5, wherein the horizontal wing driving module 5 is connected with the sliding rod 4 and drives the sliding rod 4 to enable the horizontal wing 2 to move longitudinally. The horizontal wing driving module 5 takes motor driving as power, and the sliding rod 4 is driven to realize linear motion through the transmission assembly. By the design, the horizontal wing can be positioned and adjusted no matter the underwater glider is thrown in or before or after the underwater glider is thrown in, and the applicability of the underwater glider is improved.

Exemplarily, as shown in fig. 1, in order to optimize the internal structure of the underwater glider and the arrangement of the center of gravity thereof, the horizontal wing 2 is arranged behind the center of gravity of the glider body 1; the head part of the glider main body 1 is provided with a buoyancy adjusting module 6 for adjusting the buoyancy of the glider main body 1; the middle part of glider main part 1 is equipped with group battery 7, group battery 7 respectively with buoyancy regulation module 6 with horizontal wing drive module 5 electricity is connected. The buoyancy adjusting module 6 is a buoyancy adjusting device special for the existing underwater glider. When the underwater glider works, the buoyancy is zero, and the underwater glider is suspended in water; the buoyancy adjusting module 6 controls the buoyancy of the underwater glider to be negative buoyancy, and the underwater glider begins to sink; because the horizontal wings 2 are arranged at the tail end (behind the gravity center) of the underwater glider, the whole underwater glider is asymmetrical front and back, in the sinking process, the back half part of the underwater glider is subjected to a lifting force (the direction is upward) larger than the front half part, the underwater glider is firstly inclined and is stabilized at an initial inclination angle, the underwater glider glides downwards and forwards, and the direction of the gliding movement is controlled by the rudder 9; after the water reaches the designated water depth, the buoyancy adjusting module 6 controls the buoyancy of the underwater glider to be positive buoyancy, the underwater glider floats upwards, in the floating process, the rear half part of the underwater glider is subjected to lift force (downward direction) and is larger than the front half part, the underwater glider tilts backwards and is stabilized at a tail tilt angle, the underwater glider glides upwards and forwards, and the rudder 9 is adopted to control the direction of the gliding movement.

Exemplarily, as shown in fig. 1 and 2, the horizontal wing 2 is made of an elastic material, and the horizontal wing 2 is fixed by a bundling piece 8 and is in a curling storage state before the underwater glider enters water; after the underwater glider enters the water, the tie members 8 are released to allow the horizontal wings 2 to be freely deployed. Therefore, the horizontal wing 2 is made of elastic materials, the horizontal wing 2 can have the curling deformation characteristic, and the bundling piece 8 is adopted to fix the curling shape of the horizontal wing 2, so that the horizontal wing 2 is in a curling storage state before the underwater glider drops into water, and the storage and the transportation are convenient; meanwhile, after the underwater glider is thrown into water, the bundling piece 8 can automatically loosen the horizontal wing 2 in the curling and accommodating state, and at the moment, the horizontal wing 2 can be freely unfolded under the action of the elasticity of the horizontal wing 2 and can be restored to the horizontal state; therefore, the structure form of the horizontal wing 2 for storage and expansion has the advantages of simple structure, convenient use and strong reliability.

Illustratively, the beam-forming element 8 is made of a water-soluble material. After glider entered water under water, restraint type 8 can meet water and dissolve, loosens horizontal wing 2 and makes its freedom expansion, further improves reliability and convenience that horizontal wing 2 accomodates and expands. In this embodiment, the water-soluble material is preferably water-soluble cotton or water-soluble plastic.

Illustratively, to ensure that the horizontal wing 2 is maintained in a horizontal state after being unfolded, the elastic material is a memory alloy, rubber or memory plastic.

For example, to facilitate the rolling storage of the horizontal wing 2, the following two storage forms may be adopted according to the longitudinal position of the horizontal wing 2: first, when the horizontal wing 2 moves away from or approaches the glider body 1, the horizontal wing 2 is rolled around the sliding rod 4 to be accommodated, as shown in fig. 2; second, when the horizontal wings 2 are placed on the glider body 1, the horizontal wings 2 are wound around the glider body 1.
