[0060] The scanner can scan the rotation of the fan blades of the wind farm, and transmit the scanned image to the wireless receiver through the wireless transmitter. The wireless receiver receives the information transmitted by the wireless transmitter and displays the rotation trajectory of the fan blades on a display screen.

[0061] Preferably, the laser transmitter, distance sensor, scanner and wireless transmitter are all installed on the surface of the moving plate, and the display is installed inside the pedal frame.

[0062] Embodiment 3:

[0063] According to a maintenance method used by a maintenance system for wind farm maintenance and repair, the method steps are as follows:

[0064] S1. Use the high-altitude lift to adjust the position of the scanner and laser light and select the position;

[0065] S2, the offset detection module in the system performs normal detection on the offset distance and the circuit detection module;

[0066] S3, real-time transmission and display through wireless transmitter during detection;

[0067] S4. After the display, the trajectory is judged and monitored through the cooperation of the system and personnel, thereby achieving maintenance of the wind farm.

[0068] The working principle and use process of the present invention: During the actual use of the wind farm maintenance and inspection device, the user enters the inside of the pedal frame 2, and then hangs the safety belt between the circular column 701 and the circular column 701. The circular column 701 increases the stability between the pedal frame 2 and the circular column 701 through the circular ring 704 and the vertical pole 705, thereby preventing the circular column 701 from falling off from the pedal frame 2. The fluorescent light strip 703 inside the circular column 701 can take pictures of the inside of the pedal frame 2 at night, so that it is convenient for the user to observe the inside of the pedal frame 2, which can facilitate the hanging of the user's safety belt and reduce the difficulty of hanging the user's safety belt. At the same time, it can illuminate the inside of the pedal frame 2, reduce the blind area inside the pedal frame 2, and then facilitate the personnel to walk inside the pedal frame 2;

[0069] Then the user rotates the rotating bar 602 along the rotating block 601, so that the rotating bar 602 and the top of the treading frame 2 fit together, and then the user moves the slider 605 along the slide groove 604 to move the concave frame 606. When the concave frame 606, the circular hole 607 and the circular hole 607 of the rotating bar 602 coincide with each other, the user puts the connecting plate 609 into the concave frame 606. At this time, the column 608 fixes the concave frame 606, the slider 605 and the rotating bar 602 along the circular hole 607. Then the user puts the parts into the concave frame 606, which can facilitate the separation of the people in the treading frame 2 and prevent the people in the treading frame 2 from colliding with each other. At the same time, it can facilitate the placement of maintenance tools by the users, reducing the difficulty of placing maintenance tools by the users.

[0070] Finally, the first motor 304 is controlled by the operating table 4 to connect to the power supply and start running. When the first motor 304 is running, it drives the rectangular block 307 to move along the inside of the rectangular groove 303, thereby driving the moving bar 308 to move. When the moving bar 308 moves, it drives the limit block 306 to move along the inside of the limit groove 302. When the moving bar 308 moves, it drives the moving plate 312 to move up and down. When the moving plate 312 moves up and down, it drives the scanner 313 and the laser light 314 to move up and down. Then, the operating table 4 is used to control the second motor 310 to connect to the power supply. The second motor 310 is turned on and off. 310 is connected to the power supply and starts to operate normally. When the second motor 310 is running, it drives the threaded rod 311 to rotate. When the threaded rod 311 rotates, it drives the movable plate 312 to move along the inside of the groove 309, thereby driving the scanner 313 and the laser light 314 to move, which can facilitate the adjustment of the position of the scanner 313 and the laser light 314, reducing the difficulty of adjusting the position of the scanner 313 and the laser light 314, thereby making the scanner 313 and the laser light 314 scan more comprehensively, thereby increasing the scanning range of the scanner 313 and the laser light 314.
