Description

technical field [0001] The invention relates to a carrier of an underwater detection device, in particular to a submersible pump water jet propulsion belt remote control underwater robot. Background technique [0002] The cable remote-controlled underwater robot is an underwater detection device that is increasingly widely used in the dynamic monitoring of underwater environments such as oceans, rivers and lakes. There are special uses in inspection. A remote-controlled underwater robot with cables usually consists of an umbilical cable, an underwater robot, and a robot trajectory and attitude control mechanism. With the improvement of the requirements for rapid on-site monitoring of underwater environment in various countries in the world, the requirements for the trajectory and attitude control capabilities of remote-controlled underwater robots with cables under the control of the control mechanism are also continuously increasing. The working nature of the underwater e...

Problems solved by technology

The main defect of this type of control method is that multiple control propellers and complex manipulation actions are required to achieve stable control of the trajectory and attitude of the robot with different degrees of freedom, and the manipulation of these propellers also requires complex control mechanisms. In the robot motor drive propeller system, the shaft joint between the robot's internal motor system and the propulsion propeller, once water leakage occurs, the drive motor will not work normally

These factors undoubtedly increase the complexity of the design of the robot control system and the risk and difficulty of the user's work, which limits the scope of application of these robots due to the complexity of the control mechanism, the increase in the failure rate of the operation, and the difficulty in having good attitude stability.
