Eddy propeller

Abstract

The invention discloses an eddy propeller comprising a shell. The shell is provided with a water outlet and a water inlet, and a bearing seat is mounted at the top of the shell. An outboard engine is connected to the upper end of the bearing seat, and a driving shaft of the outboard engine is vertically arranged in the shell and connected with an impeller. A gap is reserved between the impeller and the shell. The outboard engine drives the impeller on the driving shaft to rotate, the small gap exists between the impeller and the shell, water flow can flow in from the water inlet and is ejected out from the water outlet along the shell without flowing back when the impeller rotates at a high speed, and the impeller rotates to drive the water flow to be ejected from the water outlet so as to generate propulsive force for propelling a ship forward or backward; by the design, the ship can be ensured to sail in shoals normally, and the problem that a conventional outboard engine impacts on underwater reefs and stumps as a result of accidents is avoided.

Description

technical field [0001] The invention relates to a vortex propeller and belongs to the technical field of outboard motor propellers. Background technique [0002] The emergence of outboard motors has provided great convenience for human water transportation. People can easily drive boats to their destinations without considering whether they have enough physical strength and skills to control the tradition of poles, paddles and sculls. However, the outboard motor has an unavoidable shortcoming. In order to ensure the propulsion efficiency, the propulsion part of the outboard motor is lower than the bottom of the ship, which means that the outboard motor will not be able to provide Power, such as a swamp with countless shoals; and when navigating in shoals, once it hits objects such as reefs and tree stumps under the water surface, it will lose power and cause casualties. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the obje...
