In the power sector, drones are widely used in power transmission and distribution lines, substations, power towers, wind farms and other fields. Drones equipped with visible light, infrared thermal imaging, laser radar, Beidou navigation, data transmission, intelligent control, high-precision sensors and other functional technologies can quickly and efficiently inspect the power grid, greatly improving the efficiency and accuracy of power inspections, while also reducing possible omissions and safety hazards in manual inspections.

[0003] After searching the prior art, the announcement number CN107554767A discloses an electric power inspection drone.

The limit block 9 can connect the transmission rod 8 to the drone body 1. The planetary gear 10 can drive the linkage rod 11 connected thereto to rotate in the opposite direction after the transmission rod 8 rotates.

[0024] The counterweight device 4 includes two groups of connecting rods 11, each group of connecting rods 11 has two connecting rods 11, and both groups of connecting rods 11 are connected to the transmission rod 8. The middle parts of the two connecting rods 11 are rotatably connected to a cross bar 12, and the cross bar 12 is rotatably connected to a support wheel 13. A counterweight battery 14 is provided at the lower end of one of the connecting rods 11. The counterweight battery 14 can adjust the center of gravity of the drone by its own weight. When the center of gravity is lower than the detection cable, it is convenient for the drone body 1 to move on the cable.

[0025] One set of the connecting rods 11 is connected to the planetary gears 10 of the transmission rod 8. The planetary gears 10 can change the rotation direction of the connecting rods 11, which is opposite to the rotation direction of the transmission rod 8.

[0026] The lower surface of the drone body 1 is provided with two folding grooves 15, and the insides of the two folding grooves 15 are rotatably connected with the detection device 6. The two sides of the detection device 6 are provided with a rotating shaft 16, and the rotating shaft 16 is provided with a transmission belt 17, and the transmission belt 17 is connected to the transmission rod 8.
