[0041] During operation, the existing drone inspection device is easy to absorb dust when in use, which affects the camera's shooting clarity and is inconvenient to observe the cable conditions. In addition, the camera lacks a protective structure, so the camera is easily damaged by bumps during operation, which affects the normal inspection. In this solution, by controlling the operation of the No. 1 motor 26, the No. 1 motor 26 drives the No. 1 gear ring 24 through the No. 1 gear 25 when the motor 26 is running, so that the rotating disk 21 rotates at the bottom of the housing 1, and the rotating disk 21 drives the protective component 3 and the support platform 11 in the protective component 3 to rotate, thereby adjusting the shooting angle of the camera 12;

[0042] During operation, the spherical protective shell 36 will protect the camera 12 on the side of the support platform 11 to prevent the camera 12 from being damaged by collision, ensure the normal inspection, and block the camera 12 through the spherical protective shell 36 to block dust on the outer surface of the spherical protective shell 36. When there is too much dust attached to the spherical protective shell 36, the second motor 35 is controlled to operate. When the second motor 35 operates, the second gear ring 33 is driven by the second gear 34, so that the second gear ring 33 drives the sleeve 31 to rotate in the fixed ring 23, and cooperates with the fixing of the support platform 11 by the hollow shaft 32, thereby driving the spherical protective shell 36 to rotate outside the support platform 11, so as to rotate the part of the spherical protective shell 36 located outside the shell 1 to the inside of the shell 1;

[0043] When the spherical protective shell 36 rotates, the liquid delivery pump 52 is controlled to operate. When the liquid delivery pump 52 operates, the cleaning agent in the liquid storage tank 51 is pumped into the fixed frame 43, and the cleaning sponge 44 is fully adsorbed with the cleaning agent. At this time, the cleaning sponge 44 fully adsorbed with the cleaning agent during the rotation of the spherical protective shell 36 will scrub the surface of the spherical protective shell 36, thereby erasing the dust attached to the spherical protective shell 36. As the spherical protective shell 36 continues to rotate, the part of the spherical protective shell 36 scrubbed by the cleaning sponge 44 will be scrubbed again by the water-absorbing sponge 42, thereby erasing the water stains and residual dust left on the spherical protective shell 36, so as to clean the outer surface of the spherical protective shell 36 and ensure the normal inspection and shooting of the camera 12.

[0044] When the camera 12 is shooting, the laser radar module 13 is used to perform laser scanning on the external scene, and three-dimensional coordinate information is established in conjunction with the real scene shot by the camera 12, and then the established coordinate information is transmitted to the terminal device for viewing through the signal transmission module 15, so as to achieve the purpose of inspection;

[0045] The cooperation can protect the camera of the drone inspection device and clean the dust attached to the outside of the camera to ensure the normal inspection.
