Abstract

The invention provides a device for passively eliminating residual buoyancy of a deep-sea underwater robot, which belongs to the technical field of underwater robots. The airbag is bonded to one side of the bottom plate, and has two passages of water and air and corresponding valves and sealing devices on the other side of the bottom plate. The ballast fixing bolts are connected with the bottom plate. The ballast can be installed on the ballast fixing bolts and pass The anti-loosening rod prevents the ballast from loosening, and the main body of the device can be installed on the robot carrier through the fixing hole. The present invention can passively lose a certain amount of buoyancy at a predetermined depth without any external control, eliminate the remaining buoyancy increased by the carrier of the deep-sea underwater robot, and at the same time not destroy the positive floating state of the underwater robot on the sea surface, and the buoyancy elimination amount It can be adjusted according to the working water depth before the robot is launched into the water, and the structure is simple and easy to use.

Description

technical field [0001] The invention relates to a zero-consumption buoyancy adjustment device, in particular to a passive elimination device for residual buoyancy of a deep-sea underwater robot, which belongs to the field of buoyancy adjustment of underwater robots. Background technique [0002] Underwater robots are widely used in marine scientific research, marine resources investigation, and marine engineering, especially deep-sea underwater robots have become an important tool for human exploration of the ocean. When an underwater robot is working underwater, compared with the increase in seawater density on the water surface and the compression of the robot carrier, the buoyancy of the robot will change, which will lead to an imbalance between gravity and buoyancy. Generally, the buoyancy of deep-sea underwater robots is slightly greater than gravity at the working depth, that is, residual buoyancy is generated, and the remaining buoyancy will affect the vertical contro...
