Technical Field
[0001] The utility model relates to the technical field of flaw detection devices, in particular to a non-destructive flaw detection device for wind turbine blades. Background Technique
[0002] Wind power generation is an important part of new energy. The safe, reliable and stable operation of wind power generation equipment is crucial for national production. Wind turbine blades are the core components of wind power generation equipment. Once damaged, they will cause high maintenance costs and huge production stoppage losses, and will also lead to serious production safety accidents. During the production process of wind turbine blades, it is necessary to detect the surface damage. Traditional detection devices are mostly held by personnel for detection, which is time-consuming and laborious. At the same time, it is inconvenient to detect when encountering larger wind turbine blades. Therefore, we propose a non-destructive flaw detection device for wind turbine blades. Content of the Utility Model
