Problems solved by technology

The movement of a general underwater robot in water has 3-6 degrees of freedom. In order to realize the controllability and flexibility of the movement of the underwater robot, it is necessary to equip the underwater robot with multiple fixed propellers, or multiple fixed propellers It is necessary to cooperate with multiple rudders, which will undoubtedly increase the complexity, volume, weight, cost, etc. of the underwater robot system.

Abstract

The invention belongs to the field of underwater robots, in particular to a steerable type propulsion system for an underwater robot. The propulsion system for the underwater robot comprises a steering cabin, a steering shaft, a transmission mechanism, a drive mechanism and an electronic unit assembly, wherein the steering shaft, the transmission mechanism, the drive mechanism and the electronic unit assembly are installed in the steering cabin, the drive mechanism is connected with the steering shaft through the transmission mechanism and drives the steering shaft to rotate, two ends of the steering shaft penetrate through two sides of the steering cabin and respectively provided with a propeller, the two propellers simultaneously rotate along with the steering shaft, the drive mechanism and the two propellers are respectively connected with the electronic unit assembly and driven by the electronic unit assembly, and therefore a plurality of degrees of freedom of the propulsion system can be achieved. The propulsion system for the underwater robot has the advantages of being simple and compact in structure, small in size, light in weight, low in cost, high in reliability, strong in controllability, complete in functions, capable of being easily installed on the underwater robot and the like.

Description

technical field [0001] The invention belongs to the field of underwater robots, in particular to a steerable propulsion system for underwater robots. Background technique [0002] An underwater robot is an extreme operation robot that works underwater. It is an underwater mobile device that can perform specific tasks underwater, also known as a submersible. The movement of a general underwater robot in water has 3-6 degrees of freedom. In order to realize the controllability and flexibility of the movement of the underwater robot, it is necessary to equip the underwater robot with multiple fixed propellers, or multiple fixed propellers. The device cooperates with multiple rudders, which will undoubtedly increase the complexity, volume, weight, cost, etc. of the underwater robot system. Contents of the invention [0003] In order to solve the above-mentioned problems of the fixed propeller, the object of the present invention is to provide a steerable propulsion system for...
