Abstract

The invention relates to buoyancy regulating equipment for an underwater robot, particularly to an automatic oil return type buoyancy regulating device for an underwater robot. The automatic oil return type buoyancy regulating device comprises an inner bladder, a DC motor, an electromagnetic valve, a plunger pump, a stern end cover and an outer bladder, wherein the stern end cover is connected with a barrel of the underwater robot in a sealed manner; the outer bladder is installed at the outer side of the stern end cover; the inner bladder, the DC motor, the electromagnetic valve and the plunger pump are respectively installed in the vacuumized barrel of the underwater robot; one end of the plunger pump driven by the DC motor is connected with the inner bladder by a pipeline, and the other end is connected with the outer bladder by a pipeline which is provided with a check valve; and the electromagnetic valve is connected in parallel between the pipeline for connecting the plunger pump with the inner bladder and the pipeline for connecting the check valve with the outer bladder. In the invention, the plunger pump operates under the driving of the DC motor to realize oil extraction, and automatic oil return is realized by opening the electromagnetic valve so as to regulate the buoyancy of the underwater robot. The automatic oil return type buoyancy regulating device has the advantages of simple structure, safety and reliability.

Description

technical field [0001] The invention relates to a buoyancy regulating device for an underwater robot, in particular to a self-returning buoyancy regulating device for an underwater robot. 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 during operation, such as a neutral state, 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, which will affect the overall performance of the underwater robot. Through the special underwater robot buoyancy adjustment device, according to the seawater density of the underwater robot's operating sea area, the drainage volume or load weight of the under...
