Working-grade underwater robot

Abstract

The invention relates to marine shallow water monitoring and working equipment, and more particularly to a working-grade underwater robot. The robot uses multiple designed bellows balance assembly structures to change the buoyant center position and buoyance magnitude of the equipment and realize the pitching and rolling movement and the up and down movement, an underwater snorkeling state can be maintained; compared with the congeneric underwater robot capable of performing buoyance adjustment, the working-grade underwater robot removes a heavy and complicated compression structure, and has the characteristics of accurate adjustment, large adjusting variable and quick response. When the robot is applied to the field of aquaculture, various demands of carrying out round-the-clock underwater monitoring on a net cage, detecting the breakage situation of the net cage and the residue situation of bait in the net cage, carrying out sick aquatic product sampling, detecting the change of the water temperature and water quality parameters, and the like are met, and the working-grade underwater robot has extremely high equipment usage frequency and good application prospect.

Description

technical field [0001] The invention relates to an ocean shallow water monitoring and operation equipment, and more particularly relates to an operation-level underwater robot. Background technique [0002] Chinese Invention Patent Application Publication CN200910220204 discloses a two-way oil-discharging buoyancy adjustment device for underwater robots. This device is driven by a DC motor with a bi-directional gear pump. Oil, thereby adjusting the buoyancy of the underwater robot; however, this solution is limited by the instability of the shape of the skin bag during oil filling and oil discharge, and the position of the buoyancy center cannot be adjusted. Chinese Invention Patent Application Publication CN201510679709 discloses a self-draining oil buoyancy adjustment device for underwater robots. The device adopts a hydraulic scheme, and through an accumulator, the bladder can actively discharge oil and passively return oil. There is also the problem that the position of ...

Problems solved by technology

Observation-level ROVs are small in size and weight, low in load, and equipped with cameras. They are often used for underwater video monitoring. The equipment has weak scalability and single functions.

Operational-level ROVs are mainly used in underwater construction, public security fire protection, scientific research and other fields. They can be equipped with hydraulic or electric underwater manipulators, and can perform underwater salvage, underwater construction underwater grabbing, underwater sampling, underwater marking, etc. operation, but often the equipment is bulky, the working noise is loud, the operation of the equipment is complicated and the cost is high
