AI Technical Summary

Technical Problem

The existing wind turbine blade maintenance equipment relies on maintenance personnel to adjust the safety ropes themselves, which causes maintenance personnel to consume a lot of physical strength, and there are safety risks and unstable rope fixation.

Method used

A blade maintenance equipment is designed, which is included in the functional room fixedly installed on the top of the wind turbine. It is equipped with a rotating shaft and a worm mechanism. The self-locking function of the safety rope is realized through the worm mechanism, and the position of the rope is adjusted through the moving mechanism to ensure that the distance between the blade and the tower body is adjustable at different heights.

Benefits of technology

The self-locking function of the worm mechanism improves the stability of the safety rope, reduces the physical energy consumption of maintenance personnel, and ensures safety and stability at different heights through the use of the moving mechanism, and reduces maintenance risks.

Abstract

The present invention discloses a blade maintenance device, which has a function room fixedly mounted on the top of a wind turbine, and a moving mechanism including an outer frame and an inner frame, the inner frame is moved laterally onto the outer frame through a lateral moving device, the outer side of the outer frame is fitted with a roller, which is used for rolling and fitting to the side wall of the tower frame of the wind turbine, and has a second rotating shaft, which is installed in the function room, and a worm gear assembly is installed in the function room, and the worm gear assembly is composed of a worm and a worm wheel to realize the self-locking of the safety rope, which is used to protect the safety of the maintenance personnel. The moving mechanism adjusts the position of the maintenance personnel, and when the blade maintenance device is used, the position of the inner frame relative to the outer frame can be adjusted, thereby adjusting the standing position of the maintenance personnel, and adjusting the relative position of the maintenance personnel when the distance between the blade and the tower body changes with the height, thereby maintaining the distance between the maintenance personnel and the blade, thereby completing the adjustment function.
