Bidirectional oil discharge type buoyancy regulating device for underwater robot

Abstract

The invention relates to a buoyancy regulating device for an underwater robot, in particular to a bidirectional oil discharge type buoyancy regulating device for an underwater robot. The bidirectional oil discharge type buoyancy regulating device provided by the invention comprises an inner leather bag, a direct current motor, a solenoid valve, a one-way valve, a bidirectional gear pump, a stern end cover and an outer leather bag, wherein the stern end cover is in sealing connection with an underwater robot cylinder body; the outer leather bag is mounted outside the stern end cover; the inner leather bag, the direct current motor, the solenoid valve, the one-way valve and the bidirectional gear pump are respectively mounted in the underwater robot cylinder body; the inner leather bag is connected to the bidirectional gear pump driven by the direct current motor through a pipeline; and the solenoid valve and the one-way valve are in parallel connection between the bidirectional gear pump and the outer leather bag through a pipeline. According to the invention, the bidirectional gear pump is driven by the direct current motor and the oil discharge or backflow is realized by means of the positive and negative rotation of the bidirectional gear pump, so as to regulate the buoyancy of the underwater robot. The buoyancy regulating device has a simple structure, is safe and reliable, and has strong buoyancy regulating capability. The maximum buoyancy regulating variable can be flexibly regulated just by regulating the volumes of inner and outer leather bags.

Description

technical field [0001] The invention relates to a buoyancy regulating device for an underwater robot, in particular to a two-way oil-discharging 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 ...
