[0063] When the power distribution network inspection device is started, the control module 41 controls the first driving unit 66 according to actual needs, so that it drives the rotating rod 54 and the first driving shaft 56 to rotate, and drives the threaded cylinder 52 to move up and down inside the fixed plate 51 through the meshing transmission of the first bevel gear 55 and the second bevel gear 57, so as to adjust the position of the camera body 53. When the ambient temperature is low, the temperature sensor 58 detects that the temperature is lower than the set value, and the control module 41 starts the heating ring 71 to heat the inside of the camera protection cover 7 to prevent the lens from fogging or icing, so as to ensure clear shooting effect. When there is rain or dust on the surface of the camera protection cover 7, the control module 41 starts the second drive unit 67, drives the second drive shaft 68 and the sixth bevel gear 69 to rotate, and drives the first wiper 74 and the second wiper 75 to rotate through the meshing transmission of the fifth bevel gear 517, the transmission shaft 513, the fourth bevel gear 514, the third bevel gear 512, the screw 511 and the rack 516. The first wiper 74 and the second wiper 75 clean the inside and outside of the camera protection cover 7 respectively to keep the lens clean and clear. The humidity sensor 65 set inside the component warehouse 6 monitors the environmental humidity in real time. When the humidity sensor 65 detects that the humidity exceeds the set value, the control module 41 starts the heating plate 64 for heating to reduce the humidity inside the component warehouse 6 and prevent the electrical components from getting wet. At the same time, the desiccant box 63 set in the installation frame 62 on the installation plate 61 absorbs moisture to further ensure the dry environment of the component warehouse 6.
