Description

Technical Field

[0001] The utility model belongs to the technical field of marine propellers, in particular to an environmentally friendly ceramic-based anti-corrosion composite coating on the surface of a marine propeller. Background Art

[0002] The marine propeller is a key ship propulsion device. The working principle of the marine propeller mainly depends on the rotation of the blades in the water. When the propeller rotates, the blades push the water backwards, generating forward thrust. This thrust is used to overcome the resistance of the ship and push the hull forward. At the same time, the propeller will also be affected by the resistance of the water during the rotation process. This resistance torque is overcome by the rotational torque generated by the main engine. The efficiency of the propeller depends on the ratio of the thrust it generates to the power consumed.

[0003] Existing marine propellers are generally used underwater, which causes the marine propellers to be easily worn due to the impact of water flow when used for a long time. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides an environmentally friendly ceramic-based anti-corrosion composite coating on the surface of marine propellers, which effectively solves the problem that marine propellers are prone to wear due to the impact of water flow when used for a long time.

Two springs are symmetrically fixedly connected between the movable plate and the fixed plate, and the two springs are respectively sleeved on the outer sides of the two inner rods. A reinforcing rod is fixedly connected between each wear-resistant ball and the movable plate, and each reinforcing rod passes through the fixed plate and is movably connected to the fixed plate.

[0008] Preferably, the wear-resistant layer is made of ultra-high molecular weight polyethylene.

[0009] Preferably, a plurality of grooves 2 are equidistantly provided on the top of the ceramic substrate, and a plurality of ridges 2 are equidistantly provided on the bottom of the anti-corrosion layer.

The ridges 1 and the wear-resistant layer are an integral structure, and each ridge 1 is located inside each ridge 2.

[0011] Preferably, the anti-corrosion layer is made of epoxy resin paint.
