Abstract

The invention provides an underwater propeller, and belongs to the field of underwater power propelling equipment. The underwater propeller comprises a shell, a driving component, a driving shaft, a first impeller and a second impeller; a fluid channel and a containing cavity are arranged in the shell, the fluid channel comprises a water inlet and a water outlet; a pressurization area is arrangedin the fluid channel, and the inner diameter of the pressurization area is decreased in the drainage direction; the driving shaft is connected with the driving component; the driving component is arranged in the containing cavity; the first impeller is fixedly connected to the driving shaft, the second impeller is rotatably connected to the driving shaft, the first impeller is located at the upstream position of the second impeller, and the second impeller is located in the pressurization area. The driving component drives the first impeller to rotate through the driving shaft, and the first impeller enables the water flow to be pushed into the pressurization area; the second impeller located in the pressurization area accelerates water flow and sprays the water flow out of the water outlet, so that the propelling power is increased, the propelling power of the underwater propeller is improved, and the driving effect is improved.

Description

technical field

[0001] The invention relates to the field of underwater power propulsion equipment, in particular to an underwater propeller. Background technique

[0002] The underwater thruster is a multi-purpose underwater power propulsion equipment, which can be installed on the bottom of equipment such as surfboards or small hulls to provide propulsion power. At present, the underwater propeller used for equipment such as surfboards or small hulls usually includes: a motor, a drive shaft, a propeller and a cylindrical shell. Travel on water equipment such as surfboards or small boats. However, the propulsion power produced by the above-mentioned propeller-type underwater propeller is limited, and the driving effect is not good. Contents of the invention

[0003] The object of the present invention is to provide an underwater propeller, which can increase the propulsion power of the underwater propeller and improve the driving effect.

[0004] Based on the above obj...
