The invention discloses a miniature underwater thruster.The miniature underwater thruster comprises a shell, a propeller shaft, propellers, a speed reducer, a motor, a magnetic coupler, a pressure pipe, a shell connecting sleeve, a propeller shaft sleeve, a sacrificial anode and a motor heat dissipation frame, a cabin formed by the shell in an enclosing mode is internally provided with the motor, the speed reducer and the magnetic coupler in sequence, one end of the magnetic coupler is connected with the output end of the speed reducer, the other end of the magnetic coupler is connected with the propeller shaft, the propellers are arranged on the propeller shaft and fixed through the sacrificial anode, the rear end of the shell is connected with the pressure pipe through a pressure pipe fixing sleeve, the shell is connected with the propeller shaft sleeve, and a magnetic separation head is arranged on the joint.The miniature underwater thruster has the advantages that the structure is compact and reasonable, the volume of the thruster is reduced, the power loss is reduced, the motor heat dissipation problem is effectively resolved, the motor can run for a long time in a super-power mode, the pressure pipe is adopted to serve as an underwater channel of an electric wire, and the problem that the underwater thruster energy and control signal transmission is inconvenient is solved.
Description
technical field [0001] The invention relates to the technical field of underwater thrusters, in particular to a miniature underwater thruster. Background technique [0002] The underwater propeller is the power source of the underwater robot, and the micro underwater propeller plays a vital role in the micro underwater robot. Miniature underwater robots have the characteristics of small size, light weight, compact structure, and flexible movement. The depth is small and the power loss is large. Contents of the invention [0003] The invention provides a micro underwater propeller, which can improve the problems of large volume, large mass, large power loss and small working depth of the underwater propeller, and can provide favorable support for solving the power problem of the micro underwater robot. [0004] In order to solve the above technical problems, the embodiment of the present application provides a miniature underwater propeller, including a casing, a propelle...
