The invention discloses a fiber composite marine propeller comprising a connection shaft, a first buffer layer, a supporting layer, and a second buffer layer. The outer surface of the connection shaftis provided with propeller blades, and the connection shaft is internally provided with a connection hole. The front end of the connection shaft is provided with a fixed pipe, a casing pipe is arranged on the body wall of the fixed pipe, and connecting springs are arranged inside the casing pipe. The first buffer layer is arranged inside the propeller blades, the first buffer layer is internallyprovided with a first support plate, the supporting layer is disposed on the lower surface of the first buffer layer, support rods are disposed inside the supporting layer, the second buffer layer isdisposed on the lower surface of the supporting layer, and a second support plate is disposed inside the second buffer layer. According to the fiber composite marine propeller, the propeller blades are internally provided with support plates, the support plates are in an arch shape, when the propeller blades rotate, the extrusion force on the propeller blades from current is reduced, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the technical field of marine propellers, in particular to a marine propeller made of fiber composite materials. Background technique [0002] A propeller is a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There can be two or more blades connected to the hub. Now there are various marine propellers on the market, such as Take the marine propeller of fiber composite material as an example, the current marine propeller of fiber composite material cannot be better fixed when it is in use, and it is squeezed by the water flow when it rotates, which cannot meet the actual work. Therefore, there is an urgent need on the market to improve the technology of marine propellers made of fiber composite materials to improve this equipment. Contents of the invention [0003] The purpose of the present invention is to provide a marine propeller of fiber composite materia...
