It should be noted that, on the side wall of one of the vertical plates 3, there is a mounting head 21 for mounting a wind turbine blade. It should be noted that, since the mass of the wind turbine blade is small, it can be directly mounted and supported through the mounting head 21. In the middle part of the side wall of the horizontal plate 2, a plurality of support plates 4 are fixedly connected;

[0027] When monitoring the upper side of the wind turbine blades, the wind turbine blades need to be flipped, which may easily cause damage to the wind turbine blades. For this purpose, a monitoring mechanism 5 is provided for fault monitoring of the wind turbine blades. The monitoring mechanism 5 includes a circular ring 6 arranged below the horizontal plate 2. The cross section of the circular ring 6 is U-shaped. A gear ring 7 is rotatably connected inside the circular ring 6. A monitoring camera 8 is fixedly connected to the inner wall of the gear ring 7.

The driving shaft of the rotating motor 12 rotates through the fixed plate 10 and is coaxially fixedly connected to the driving gear 11. The gear ring 7 is provided with an annular tooth groove meshing with the driving gear 11.

[0028] Through the above technical features, the rotating motor 12 drives the driving gear 11 to rotate, the driving gear 11 drives the gear ring 7 to rotate, and the gear ring 7 drives the monitoring camera 8 to rotate, so that the rotating motor 12 can rotate around the wind turbine blade to monitor both sides thereof.

[0029] When monitoring the wind turbine blades, it is necessary to monitor them in all directions. For this purpose, a driving mechanism 13 is provided to drive the ring 6. The driving mechanism 13 includes four sprockets 14, which are respectively fixedly connected to the two vertical plates 3. The two sprockets 14 on the right vertical plate 3 are connected by a transmission mechanism 15. Specifically, the transmission mechanism 15 includes two pulleys 20, which are respectively coaxially fixedly connected to the two sprockets 14.
