[0001] The utility model belongs to the technical field of thermal infrared flaw detection equipment, and particularly relates to a thermal infrared flaw detection equipment for wind turbine blades. Background Technique

[0002] Wind turbine blades are one of the most critical components of wind turbines. With the continuous increase in the single-unit power of wind turbines, the rotor blades are getting larger and larger, and the requirements for quality reliability are also getting higher and higher. Wind power blades are made of composite materials. During the operation of the wind turbine, on the one hand, the blades need to bear great mechanical stress, and on the other hand, they will be affected by the adsorption of insects and various dirt, sand erosion, rain erosion, lightning strikes and other erosions. These factors will cause the aging of the composite materials and structures of the wind power blades, mainly manifested as cracks, fissures and other damages of the blades, which will bring greater potential safety hazards and endanger the personal safety of the operation and maintenance personnel of the wind farm. During the production process of the blades, since most wind power blades are produced manually with low automation, various defects such as voids, wrinkles, poor resin content in the shell, core material missing, gaps, etc. also exist during the production process. And most of the defects exist inside the blade composite material, and the type, size and degree of the defects cannot be directly seen from the outer surface.

[0024] Embodiment 1, a thermal infrared flaw detection device for a fan blade, comprising a safety frame 1 and a thermal infrared flaw detection body 2, characterized in that:

[0025] A lifting bracket 3 is slidably arranged on the safety frame 1, and the lifting bracket 3 is driven by a first power device.

[0032] Both the installation groove 5 and the second sliding groove 15 are arranged as dovetail grooves, and the installation block 6 is arranged as a dovetail block.

[0033] During use, first install the thermal infrared flaw detector body 2. The thermal infrared flaw detector body 2 is provided with an installation block 6 and is installed on the installation bracket 4 along the installation groove 5. Since the installation groove 5 and the installation block 6 are arranged as dovetail grooves and dovetail blocks, they have a certain limiting function to prevent the thermal infrared flaw detector body 2 from detaching from the installation bracket 4.
