Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade detection, in particular to a wind turbine blade crack detection mechanism. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. During the production process of wind turbine blades, detection agencies are needed to detect cracks on their surfaces.

[0003] Patent No. CN202321574218.9 discloses a wind turbine blade crack detection mechanism, including a base, wherein electric guide rails are arranged on both sides of the top of the base; connecting rods are arranged at the output ends of the two groups of the electric guide rails, and the two groups of the connecting rods are connected to the guide device, and a rotating device is arranged on the guide device; a fixed seat is arranged on the rotating device, and an electric telescopic rod is arranged on the fixed seat, and a detection head is arranged on the output end of the electric telescopic rod.

[0004] In the above patent, during use, the electric guide rail can drive the detection head to move along the length direction of the wind turbine blade, and the guide device guides the gear ring so that the gear can drive the detection head to rotate around the wind turbine blade, and then the electric telescopic rod is used to drive the detection head close to the wind turbine blade, so that crack detection can be performed on the surface of the wind turbine blade. Compared with manual detection, not only the work efficiency is improved, but also the work intensity is greatly reduced. However, during the detection process, when a crack is detected, if the device stops and waits for the staff to confirm, the detection efficiency will be low. If the device continues to move for detection, it will be inconvenient to determine the crack location later because it cannot be marked, which causes inconvenience to the staff and affects the use effect of the device.
