A foldable underwater glider solar wing panel deployment mechanism

Abstract

The invention discloses a solar wing plate expansion mechanism for a folding underwater glider. The area of the solar cell panels of a solar underwater glider is expanded through designing a folding expansion mechanism to effectively shorten the charging time of the solar underwater glider on the water surface, so the effective underwater working time of the solar underwater glider is prolonged, and the cruising range of the glider is improved. The solar wing plate expansion mechanism is composed of direct current motors, a gear group, transmission shafts, a mounting support and a plurality ofsolar wing plates, the direct current motors reduce the speed through the gear group, a driving torque is transmitted to solar wing plate rotating shafts positioned at two sides of the underwater glider through the transmission shafts, and the solar wing plates expand forwards and backwards, so the area of the solar wing plates of the solar underwater glider is effectively expanded, thereby the area of the wing plates is greatly increased; and the charging time of the solar underwater glider during the floatation at the sea with changeable water surface environments is shortened, the safety and the reliability of the glider are improved, and technologic support is provided for long-distance ocean voyage.

Description

technical field [0001] The invention relates to the field of underwater glider, in particular to a folding solar wing panel unfolding mechanism of an underwater glider. Background technique [0002] An underwater glider (Autonomous Underwater Glider, AUG) is a kind of unmanned underwater vehicle. Because it uses net buoyancy and attitude angle adjustment to obtain propulsion, energy consumption is small, and only a small amount of energy is consumed when adjusting net buoyancy and attitude angle. , and has the characteristics of high efficiency and long endurance. Compared with traditional underwater vehicles, underwater glider has the characteristics of long operating time, long sailing distance, low operating cost and less dependence on the mother ship. The use of underwater glider for marine environment monitoring and measurement will help to improve the time and space density of marine environment observation, and improve the ability of human beings to monitor the marin...

AI Technical Summary

Problems solved by technology

The solar underwater glider solves the problem of high frequency of supplementary energy for the aircraft caused by long-term underwater operations; however, due to the low conversion efficiency of solar panels, the efficiency of practically applied crystalline silicon solar panels is less than 20%. In the case of a certain area of ​​the solar panel, the surface charging time of the solar underwater glider will be longer, and the effective underwater operation time will be shortened.

[0004] Japanese researchers have developed a solar-powered AUG prototype "SORA". The wings of this prototype are equipped with groups of solar panels, but due to the limited area of ​​the wings, the area of ​​the solar panels cannot be expanded, resulting in a long charging time.

[0005] In the patent CN203780780U, "a solar-powered underwater robot" is disclosed. The robot provides energy for the aircraft through the solar panel arranged on the surface of the robot shell, but the upper end surface area of ​​the shell of the robot is small, and it floats to the water surface for The charging time is too long, which shortens the effective underwater operation time
