Problems solved by technology
When wind power workers repair wind turbine blades, due to the large size of the blades, they cannot quickly find the damaged parts of the blades and reach the designated location for repairs, so they need to work at high altitude for a long time
The existing wind turbine blade repair process requires a lot of manpower and material resources, and long-term high-altitude operations will increase the probability of safety accidents for workers

The invention provides a wind turbine blade maintenance method and device assisted by an unmanned aerial vehicle, and relates to the technical field of wind turbine blade damage identification and damage localization. According to the method, the center of a wind turbine hub serves as an unmanned aerial vehicle inspection flight path auxiliary reference point, and a to-be-inspected blade is inspected according to a specified path through the unmanned aerial vehicle; and error determination is carried out on the inspection image. According to the overhauling method, early-stage damage identification is provided for manual blade repairing, the cost is controllable, the shot inspection image accurately corresponds to the area on the wind turbine blade, and efficient damage positioning can be carried out.
Description
technical field [0001] The present application relates to the technical field of wind turbine blade damage identification and damage location, and in particular, to a method and device for repairing wind turbine blades assisted by an unmanned aerial vehicle. Background technique [0002] Wind power energy will gradually exert its important influence under the "dual carbon" strategic goal. As the main force to promote the "30.60 goal", the wind power industry will enter a new stage of accelerating quality improvement during my country's "14th Five-Year Plan" period. stage. During the operation of the wind turbine, the blades are often exposed to severe weather conditions such as low temperature and lightning strike. During the operation, they are stimulated by variable loads for a long time and are prone to corrosion, resulting in leading edge cracking, lightning strike damage, icing, and blade root fracture. The leaves are in a sub-healthy working state. Therefore, wind pow...
