AI Technical Summary
Technical Problem
The problem of existing underwater unmanned vehicles being lost when the drive power fails.
Method used
The compressed energy storage design is adopted, and the liquid volume in the tank is changed by inverting the airfoil horizontal wing and liquid injection and discharge assembly, and the underwater pressure is used to adjust the liquid volume in the tank to achieve buoyancy adjustment, ensuring that it can automatically float when the power failure is made.
Benefits of technology
When the power failure occurs, the sinking force of the horizontal wing disappears, the volume of the gas chamber increases, and the buoyancy increases, and the vehicle can quickly float to the water surface to avoid loss.

Abstract
The invention relates to the technical field of underwater vehicles, and provides a compression energy storage type underwater vehicle which comprises a body, a propeller, a liquid injection and drainage assembly and a horizontal wing. The body is provided with a hollow cavity; the propeller is arranged on the body and used for driving the body to advance. The liquid injection and drainage assembly comprises a gas bin, a liquid bin and a deformation part, the gas bin and the liquid bin are both arranged in the cavity, the deformation part is connected with the gas bin and the liquid bin, and the liquid bin is configured to adjust the volume of liquid in the bin according to the underwater pressure so as to act on the deformation part to change the volume of the gas bin and change the buoyancy of the body. Each horizontal wing is provided with an inverted wing shape, the two horizontal wings are symmetrically arranged on the two sides of the body, and each horizontal wing can be folded relative to the body so that the unfolding angle of the horizontal wings relative to the body can be changed. The size of sinking force can be adjusted, buoyancy is changed under the action of underwater pressure, the snorkeling depth of the aircraft can be adjusted when the aircraft dives, and the aircraft is prevented from being lost when the power of the propeller breaks down.
