Underwater buoyancy adjusting device

Abstract

The invention discloses an underwater buoyancy adjusting device which comprises a sealing shell, a gasbag, a control module, an exhaust module and an inflation module. The gasbag is arranged outside the sealing shell, and the control module, the exhaust module and the inflation module are arranged inside the sealing shell. The inflation module is connected with the gasbag through an inflation pipesealing cabin penetrating piece, and an exhaust pipeline of the exhaust module communicates with an inflation pipeline of the inflation module. According to the underwater buoyancy adjusting device,a high-pressure pneumatic buoyancy system is adopted, a high-pressure gas source is adopted as buoyancy adjusting driving force, compared with a traditional buoyancy adjusting system, the weight is low, the maintaining cost is low, rapid replacement can be achieved, the weights of loads are reduced, and lightweight design of amphibious aircrafts is facilitated; and by arranging a safety valve, thesituation that under the condition that a controller breaks down or the large measuring error is generated by a gas pressure sensor inside the gasbag, superscalar excess gas is automatically releasedto the annular gasbag and thus gasbag blasting is caused is avoided.

Description

technical field [0001] The present invention relates to the field of underwater robots, in particular to an underwater buoyancy regulating device, and more specifically, the present invention relates to a small and lightweight buoyancy regulating device for sea-air amphibious vehicles. Background technique [0002] The sea-air amphibious vehicle is a new type of underwater robot, a high-mobility cross-media carrier platform that can simultaneously conduct aerial, surface and underwater detection. It can be deployed and recovered in flight through shore base or ship deck, and has the functions of air flight control, positioning, surface landing in designated sea areas, autonomous surface cruise, autonomous underwater navigation and flight return. It is used in marine environment monitoring and sea-air joint observation It has broad application prospects. [0003] The buoyancy adjustment device is one of the core components to realize the automatic diving, floating and depth ...

AI Technical Summary

Problems solved by technology

Most of the existing large-depth ocean buoyancy adjustment devices use liquid oil pumps or piston cylinders to absorb and discharge oil, and the devices are heavy and have low adjustment capabilities.

If you want to improve the buoyancy adjustment capability, you must increase the volume of the device and increase the amount of hydraulic oil, which will lead to a substantial increase in the weight of the buoyancy adjustment device, thus requiring a flight power system with a greater load capacity, which will also increase the rate of energy consumption
