Abstract
An underwater thruster with improved guide stability and increased kinetic energy utilization rate comprises a power part and a propeller, wherein the power part is provided upstream of the propeller for driving the propeller to rotate. The underwater thruster further comprises a diversion part which is provided between the water inlet part and the water outlet part and is connected with the water inlet part and the water outlet part respectively in a plug-in manner, to uniformly disperse water entering the water inlet part to blades of the propeller.
Claims17
An underwater thruster, comprising a power part and a propeller, wherein the power part is provided at the upstream of the propeller to drive the propeller to rotate, the underwater thruster further comprising:

- and
- a water outlet part, which is provided at the downstream of the water inlet part, one end of the water outlet part being provided with a water outlet,
- wherein the water inlet part is adjacent to the propeller and provided at the upstream of the propeller, and the propeller is provided inside the water outlet part;
- and
- further comprising a diversion part, which is provided between the water inlet part and the water outlet part and is connected with the water inlet part and the water outlet part respectively in a plug-in manner, to uniformly disperse water entering the water inlet part to blades of the propeller, wherein the diversion part comprising:
- a diversion shell;
- a central disc;
- and
- a plurality of guide pieces, which are distributed circumferentially of the diversion shell, and connect the diversion shell and the central disc, with a guide channel being formed between two adjacent guide pieces.
