A buoyancy adjustment and pressure compensation system and method for a submersible

Abstract

Provided is a diving instrument buoyancy control and pressure compensation system and method, the system includes a shell body, the inside of the shell body is filled with gases with a certain compressive stress, the shell body is provided with two and above elastic gasbags, the insides of the elastic gasbags are filled with gases with a certain compressive stress, and through a protective shell with holes wrapping on the outsides of the elastic gasbags, are in contact with the inside and outside of the shell body, the stresses of the filled gases inside every elastic gasbag are all different, and the gas stress inside the shell body is lower than the gas stress inside the elastic gasbag; the inside of the shell body is provided with an elastic water bag, a two-way seawater hydraulic pressure pump and a seawater electric magnetic valve, and the elastic water bag through the above two-way seawater hydraulic pressure pump and the seawater electric magnetic valve is through connected with a water environment outside the shell body in order to conduct water transmission among each other; the inside of the shell body is also provided with a motor connected with the two-way seawater hydraulic pressure pump, the motor controls the control system of the motor and the seawater electric magnetic valve in operations and the electric power supply for supplying electricity to every installation inside the shell body. The disclosed diving device buoyancy control and pressure compensation system, wherein the buoyancy control is converted from a closed form oil hydraulic pressure to an open form sea water hydraulic pressure, expands the scope of the buoyancy control, and increases the reliability and compatibility with environment.

Description

technical field [0001] The invention belongs to the field of buoyancy adjustment and pressure compensation devices for submersibles, in particular to a buoyancy adjustment and pressure compensation system and method suitable for underwater robots, underwater observation platforms and other underwater submersibles in the field. Background technique [0002] Currently, there are three options for the buoyancy drive of the submersible: [0003] The first scheme is to utilize the high-pressure gas in the high-pressure cylinder to displace the seawater in the water tank to realize buoyancy adjustment. The gas pressure of this solution needs to be higher than the water depth pressure. When the water depth increases to a certain level, the volume required for the gas source generating device will increase sharply, and the energy consumption will increase sharply, so it cannot be used in deep sea. [0004] The second scheme is to adopt outer soft oil bag, inner pressure-resistant o...

AI Technical Summary

Problems solved by technology

Although this buoyancy control scheme is simple in system, it still needs a high-pressure pump (≥ water depth pressure) and a water tank pressure compensation system, which consumes a lot of energy and is limited by the difficulty of achieving high pressure in seawater hydraulic pressure

[0006] In short, as the observation depth increases, the environmental pressure on the submersible cabin increases accordingly, and the existing technical solutions cannot well solve the problems of the submersible in buoyancy drive and pressure compensation.
