AI Technical Summary

Technical Problem

The existing wind turbine blades are prone to accumulate impurities such as dust during long-term use, and are inefficient in cleaning efficiency and dangerous, and the rotation effect is average when the wind is low.

Method used

A wind turbine blade replacement mechanism is designed, and the cleaning ring pair is achieved by installing rotating blocks, limiting grooves, connecting blocks, extrusion bumps, slide chutes and elastic mechanisms on the blade shaft. Clean the surface of the blade and provide reverse thrust through elastic strips, springs and elastic pads, which promotes the reciprocating movement of the slider and improves the self-cleaning and rotational performance of the blade.

Benefits of technology

The self-cleaning effect of the blade is achieved, the rotational performance of the blade is improved, the installation and disassembly are easy, and good rotational inertia and fixing stability are maintained when the wind is low.

Abstract

The utility model discloses a wind driven generator blade replacing mechanism which comprises a blade shaft, rotating blocks are evenly installed outside the blade shaft, limiting grooves are formed in one sides of the rotating blocks, connecting blocks are installed inside the limiting grooves, extrusion protruding blocks are evenly installed on the two sides inside the limiting grooves, and the extrusion protruding blocks are connected with the connecting blocks. And fixing mechanisms are arranged on the two sides of the connecting blocks correspondingly, blade bodies are installed at the top ends of the connecting blocks correspondingly, and reinforcing strips are connected to the bottom ends of the two sides of each blade body and the two sides of the corresponding connecting block correspondingly. The sliding blocks are matched with the sliding grooves, the sliding blocks move under the rotating action of the blade body, so that the cleaning ring can clean the surface of the blade body, certain reverse thrust is provided for the sliding blocks under the action of the elastic strips, the springs, the top plate and the elastic cushion, reciprocating motion of the sliding blocks is promoted, and the cleaning effect of the blade body is improved. Therefore, the self-cleaning effect of the blade body is achieved.
