Problems solved by technology

In the patent application number CN201710295556, a magnetically driven water jet propulsion pump is described. The motor drives the driving wheel to drive the driven wheel, thereby driving the inner and outer magnetic rotors, and finally driving the impeller to rotate. The whole process has undergone three energy conversions. That is, electrical energy-mechanical energy-magnetic energy-mechanical energy will inevitably cause energy loss

Abstract

The invention aims at providing a water jet propulsion device of a triangle rotor. The water jet propulsion device comprises a shell, a triangle rotor body, a driving gear and a driven gear. The triangle rotor body is arranged in the shell, the three angles of the triangle rotor body make contact with the inner wall of the shell, the driven gear is arranged in the triangle rotor body and fixed to the triangle rotor body, teeth of the driven gear are located on the inner wall of the driven gear, the driving gear is fixed to a transmission shaft, teeth of the driving gear are located on the outer wall of the driving gear, the driving gear and the driven gear are engaged, a water inlet and a water outlet are formed in one side of the lower end of the shell, a filter is connected with the water inlet, the water outlet is connected with a jet pipe, the jet pipe is fixedly connected with a steering device, and a jet opening is connected with the steering device through a bearing. Water currents can be pressurized in the electric energy-mechanical energy one-time energy conversion process, energy losses are effectively reduced, the propulsion efficiency is improved, and energy output of a main machine is saved.

Description

technical field [0001] The invention relates to a ship device, in particular to a ship propulsion device. Background technique [0002] The water jet propulsion device is a new type of special power device. Different from the common propeller propulsion method, the thrust of the water jet propulsion is obtained by the reaction force of the water flow ejected by the propulsion pump. In the patent application number CN201710295556, a magnetically driven water jet propulsion pump is described. The motor drives the driving wheel to drive the driven wheel, thereby driving the inner and outer magnetic rotors, and finally driving the impeller to rotate. The whole process has undergone three energy conversions. That is, electrical energy-mechanical energy-magnetic energy-mechanical energy will inevitably cause energy loss. Contents of the invention [0003] The object of the present invention is to provide a triangular rotor water jet propulsion device which can effectively reduc...
