At the same time, under the action of the radar sensor 21, obstacle detection can be carried out in the front, and the information is transmitted to the controller of the inspection UAV through the control box 14. Under the action of the infrared sensor 23, obstacle detection can be carried out near the propeller 13, so that the inspection UAV can automatically avoid obstacles, and the propeller 13 can be protected under the action of the protective circle 22 to realize the obstacle avoidance function of the inspection UAV.

[0026] Further, as shown in Figure 3 shown, a connection and reinforcement mechanism 3 is provided between the wings 12. The connection and reinforcement mechanism 3 is composed of a support base 31, a sleeve frame 32, a reinforcing frame 33, and a fastening bolt 34.

[0031] Subsequently, the camera 11 is placed below the body 1, the outer spiral ring 43 is sleeved outside the inner spiral ring 42, and then the camera 11 is rotated. The camera 11 drives the outer spiral ring 43 to rotate, and the camera 11 is fixed under the thread fit of the outer spiral ring 43 and the inner spiral ring 42. At the same time, when the outer spiral ring 43 rotates, the clamping block 411 is squeezed and contracted into the inside of the sliding frame 413. Since when the outer spiral ring 43 and the inner spiral ring 42 are thread-fastened, the card slot 414 is located on one side of the clamping block 411, the clamping block 411 is clamped into the inside of the card slot 414 under the thrust of the pressing spring 412, so as to fix the outer spiral ring 43 and prevent the outer spiral ring 43 from loosening, so as to realize the function that the inspection UAV is convenient for disassembling and assembling the camera 11, thereby improving the convenience degree when the inspection UAV disassembles and assembles the camera 11.

[0032] Subsequently, through the cooperation of the controller of the inspection UAV and the control box 14, the inspection UAV is controlled to take off, and under the action of the camera 11, the environment is photographed and inspected. At the same time, under the action of the radar sensor 21, obstacle detection can be carried out in the front, and the information is transmitted to the controller of the inspection UAV through the control box 14.
