Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a propeller for ship braking. Background Art

[0002] A ship is an important water vehicle, and a propeller is one of the key components during the ship's travel on the water surface. Its main function is to push the ship forward. The propeller generally consists of a propeller or a water wheel. The propeller is a rotating device with spiral blades. When it rotates, it will push the water backward, thus generating a forward thrust. The water wheel is a device that drives the blades to rotate through the water flow. When the water flow passes through the water wheel, it will drive the water wheel to rotate, thus generating a forward thrust. Whether it is a propeller or a water wheel, they need to be driven by an engine or other power sources to achieve the function of pushing the ship forward.

[0003] During the rotation of the traditional ship propeller, the water source will continuously strike the outer shell sleeved on the outer end of the propeller, thus generating noise and easily causing damage to the outer shell.
