Abstract

The invention relates to the technical field of underwater navigation equipment, in particular to a thruster flow passage structure, a thruster and an underwater vehicle. The thruster flow passage structure comprises a flow guide pipe, and the flow guide pipe is provided with a front end and a rear end which are opposite to each other. The radial cross section of the flow guide pipe is in a circular ring shape. The outer diameter of the flow guide pipe decreases gradually from the rear end to the front end in the axial direction of the flow guide pipe. The inner diameter of the flow guide pipe firstly gradually decreases to a first set value, and then increases gradually from the first set value from the rear end to the front end in the axial direction of the flow guide pipe. The thruster comprises a power device, a propeller and the thruster flow passage structure. The flow guide pipe is fixedly connected with a shell of the power device, and the power device is used for driving the propeller to rotate. The underwater vehicle comprises the thruster. The thruster flow passage structure, the thruster and the underwater vehicle improve the working efficiency of the propeller to water, facilitate improvement of the thrusting efficiency of the thruster, and increase the thrust.

Description

Technical field [0001] The invention relates to the technical field of underwater navigation equipment, in particular to a propeller flow channel structure, a propeller and an underwater vehicle. Background technique [0002] When the propeller of the underwater vehicle in the prior art is propelled, the underwater flow field tends to reduce the thrust generated by the propeller of the propeller, which is not conducive to the improvement of the propulsion efficiency of the propeller. Summary of the invention [0003] The purpose of the present invention is to provide a propeller channel structure, a propeller and an underwater vehicle to solve the problem that the underwater flow field of the underwater vehicle in the prior art will easily cause the propeller to be propelled. The thrust generated by the propeller becomes smaller, which is not conducive to the technical problem of improving the propulsion efficiency of the propeller. [0004] The present invention provides a flow ch...
