AI Technical Summary

Technical Problem

Existing technology cannot realize zero-distance inspection and maintenance of wind turbine blades, especially fan blade de-icing in winter, which causes wind turbines to be shut down in low-temperature and cold climates until spring, which is costly and impractical.

Method used

Design a wind power tower pole climbing robot, including a body, a pole climbing mechanism, a snake-shaped swing arm and a mobile working room. It adopts a multi-point support structure and can move up and down along the wind power tower pole to complete the inspection, maintenance and de-icing of wind turbine blades. It has simple structure, strong reliability, low cost and no need for disassembly operation.

Benefits of technology

It realizes zero-distance inspection and maintenance of wind turbine blades, effectively removes ice especially in winter, reduces downtime costs, and improves the operational reliability and production efficiency of wind turbines.
