A wind blade maintenance platform

Abstract

The invention discloses a wind blade maintenance platform in the field of wind power generator maintenance and detection, which includes a lifting platform corresponding to the wind blade, outer fences are arranged on the surrounding edges of the lifting platform, and a support mechanism is fixed above the lifting platform. There are several lifting motors on the outer fence, and several steel wire ropes are set corresponding to each lifting motor. The upper end of each steel wire rope is fixed to the top of the wind turbine. The motor is lifted, and the lower end of the wire rope is fixed; the outward side of the wind blade is arranged in an arc shape, and a climbing guide mechanism is provided on the mounting frame corresponding to the outward side of the wind blade, and an inclination sensor is arranged on the lifting platform. The sensor and each hoisting motor are electrically connected with the control system. The present invention can maintain horizontal up and down along the wind blade, which is safer, easy to operate and has a larger range of motion.

Description

technical field [0001] The invention belongs to the field of wind generator maintenance and detection, in particular to a wind blade maintenance platform. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The working principle of the wind turbine is relatively simple. The wind blade rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and the generator rotates under the drive of the wind blade shaft to generate electricity. Usually, the tower of the wind turbine is erected in a place with abundant wind resources, such as a place without obstacles, that is, it needs to be erected in a relatively remote place. Because the wind turbine is exposed to the external environment all the year round, the surface of the wind turbine blade is provided with a layer of gla...

AI Technical Summary

Problems solved by technology

[0003] The maintenance platform for wind turbine blades in the prior art usually moves up and down along the surface of the tower, and it is necessary to adjust the position of the blades to get close to the position of the maintenance platform to facilitate personnel maintenance. The disadvantage is that the existing large-scale wind turbines Some of the heights are as high as hundreds of meters. After the staff have been lifted into the air through the platform, it is very dangerous to start the wind turbine to adjust the position and angle of the blades; ; The clamping device is used to fix the maintenance platform and the tower, and the selected clamping device has a complex structure
