Description

Technical Field

[0001] The utility model relates to the technical field of propellers, in particular to a stainless steel propeller which is easy to disassemble and replace. Background Art

[0002] A propeller is a commonly used ship propulsion device. It consists of a hub and several blades radially fixed to the hub. The propeller is installed below the waterline at the stern of the ship. It is powered by the engine and rotates, pushing water behind the ship and using the reaction force of the water to propel the ship forward. The propeller has a simple structure, light weight, high efficiency, and is protected below the waterline.

[0003] In the prior art, a Chinese patent document with publication number CN204979199U and publication date January 20, 2016 is proposed: a propeller, comprising a hub and blades, the hub being provided with a plurality of through holes for drainage, the through holes being connected to two end faces of the hub, the plurality of through holes being evenly distributed on one end face of the hub around the circumference of the hub axis.

[0004] In order to solve the problem that the tonnage of ships is gradually increasing, the required propellers are also getting bigger and bigger. In order to fix larger blades, the hub also needs to be larger and thicker, and the corresponding resistance generated by the hub is also increased, which will cause a certain power loss problem. The existing technology uses the through holes on the hub to reduce the contact area between the hub end face and the water, so that the hub is subject to less resistance and the loss of ship power is reduced. When the ship is anchored on the water, the one-way hole can be used to prevent some organisms in the water from entering the through hole, thereby blocking the through hole. However, the propeller installation process is too complicated, resulting in too much time required for installation, resulting in reduced operational convenience. Utility Model Content
