Abstract

The invention relates to a buoyancy adjusting device, in particular to a miniature low-power-consumption ultrahigh-pressure buoyancy adjusting device for an underwater robot, which is characterized in that an end cover is used as a fixed mounting support, is used as a pressure-resistant sealing structural member of the underwater robot and is also used as a hydraulic valve block of a whole buoyancy adjusting system; the crankshaft rotates to drive the miniature single plunger unit to replace a finished hydraulic pump, the volume and weight of the buoyancy adjusting device are effectively reduced, the self-locking electromagnetic push rod is matched with the one-way valve to replace a finished hydraulic switch valve, a passive oil return system is formed through resilience force of the outer oil bag, and energy is basically not consumed. The buoyancy detection precision of the rolling diaphragm type inner oil bag system is high. The invention has the advantages of simple structure, light weight (only 800g), high working pressure (70MPa) and low energy consumption, and is widely applicable to various conventional and microminiature underwater robots.

Description

technical field [0001] The invention relates to a buoyancy regulating device, in particular to a miniature low-power consumption and ultra-high pressure buoyancy regulating device for underwater robots. Background technique [0002] As an underwater measurement and operation platform, underwater robots have been widely used in marine scientific research, marine engineering, marine resource exploration, rescue and salvage and other application fields. Usually, the underwater robot should maintain a stable buoyancy state, such as a neutral state, during the operation to ensure a normal and stable working state. However, affected by the change of seawater density, the buoyancy state of the underwater robot will fluctuate to varying degrees, thus affecting the overall performance of the underwater robot. Through the special underwater robot buoyancy adjustment device, according to the seawater density in the working area of ​​the underwater robot, the displacement volume of the...
