The development of renewable energy has great potential, and wind energy has strong advantages in technology and cost. In recent years, my country's wind power industry has continued to expand, and the installed capacity has become larger and larger. The wind turbine blades, one of the core components of wind power generation, are also getting larger and larger. If there are quality problems with the blades before leaving the factory, it will definitely cause serious consequences. Therefore, the blades need to be quality inspected before leaving the factory. After the blades are processed and produced, they need to be inspected to prevent damage to the blades, which will affect the service life and cause certain dangers. When inspecting the blades, manual handheld flaw detectors are required to inspect the blades. This kind of flaw detection is not only labor-intensive, but also has low precision and high labor costs. Among them, in order to ensure the stability of flaw detection, it is necessary to design an ultrasonic detection mechanism for the blade surface UT detection equipment to ensure that the ultrasonic detector can always fit any position and any curvature on the surface of the wind turbine blade to ensure the accuracy of flaw detection.

[0041] Working principle:

[0042] First, fix the produced wind turbine blades, move the AGV trolley 1000 to one side of the wind turbine blades, start the first hydraulic cylinder 2500 to push upward, then the first idler wheel 2510 cooperates with the first chain 2520 to drive the second support frame 2200 to slide upward in the first support frame 2100, and the second support frame 2200 moves upward, and the third support frame 2300 is driven to slide upward in the second support frame 2200 through the second idler wheel 2210 and the second chain 2220, and the third support frame 2300 moves upward, and the first mounting frame 2400 is driven to slide upward in the third support frame 2300 through the third idler wheel 2310 and the third chain 2320, that is, the extension mechanism 3000 is driven to move upward. Through the first chain 2520, the second chain 2220 and the third chain 2320, the first hydraulic cylinder 2500 can drive the first mounting frame 2400 with a high stroke at a low stroke, so that the lifting mechanism 2000 can have a larger lifting range so that it can be applied to wind turbine blades of larger models and sizes.

[0043] Secondly, the first electric cylinder 3110 pushes the first extension frame 3200, so that the first extension frame 3200 slides along the first slide rail 3210, and the first drive motor 3320 starts to drive the first gear to rotate, and cooperates with the first rack to make the second extension frame 3300 slide along the second slide rail 3310, and the scanning frame 4200 extends toward the wind turbine blade. At the same time, the first laser displacement sensor 3411 and the second laser displacement sensor 3412 measure the offset position of the scanning frame 4200, so as to calculate and adjust the overall posture of the AGV 1000, and keep it parallel to the wind turbine blade, and push the scanning frame 4200 toward the wind turbine blade by the extension mechanism 3000 until the first roller 4311 and the second roller 4321 are both against the surface of the wind turbine blade, and the scanning frame 4200 is pressed against the wind turbine blade by the first nitrogen spring 3420. The flexible first roller 4311 and the second roller 4321 are in contact with the wind turbine blades without damaging the surface of the wind turbine blades, and the second roller 4321 is rigidly connected to the first encoder 4322, which can read the actual data of the forward and backward movement of the AGV 1000 to form a data closed loop.

[0044] Then, the first cylinder 4500 drives the fifth mounting frame 5100 to move forward and backward, the second electric cylinder 5110 drives the sixth mounting frame 5200 to move up and down, and the third electric cylinder 5220 drives the seventh mounting frame 5200 to move left and right, that is, the ultrasonic detector 5520 can be driven to move in all directions, ensuring that the ultrasonic detector 5520 is close to any position of the wind turbine blade. When the ultrasonic detector 5520 is pushed toward the wind turbine blade, the articulation between the ultrasonic flaw detection frame 5500 and the seventh mounting frame 5300, and the articulation between the ultrasonic detector 5520 and the ultrasonic flaw detection frame 5500 can ensure that the ultrasonic detector 5520 can fit any curvature of the wind turbine blade, that is, ensure the detection of the ultrasonic detector 5520.

[0045] Finally, water is supplied to the spray nozzle 5510 through the water outlet box 1100 to first wet the surface of the wind turbine blades, and then the ultrasonic detector 5520 detects whether there are problems such as damage in the area; the water sprayed by the spray nozzle 5510 wets the surface of the wind turbine blades, flows into the return water frame 5400, and flows into the water outlet box through the return water frame 5400 to collect the water again. At the same time, the load-bearing capacity of the ultrasonic detection mechanism 5000 can also be reduced to avoid other problems. After completing the detection of one area, move the AGV 1000 to the next area and repeat the above actions until the detection is completed.

The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and should not be regarded as the utility model points of this utility model patent. This utility model patent will not be further elaborated.

[0047] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
