[0002] At present, with the rapid development of the power industry, power line inspection work has become more and more important. Power line inspection is divided into manual inspection by climbing the poles and inspection by power inspection drones that are easy to monitor.

[0003] When traditional power inspection drones are in flight, the camera lenses used to shoot images often become blurred due to impurities in the air. Especially during the flight phase, in order to clean the lenses, the drone must be controlled to return. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Utility Model Content

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] Example 1

[0019] See also Figure 1-4, a power inspection device for distribution network, including a drone body 1 and a camera 2, a cover 3 is fixedly provided on the bottom surface of the drone body 1, a protective cover 4 is installed on the bottom surface of the cover 3, the camera 2 is installed in the protective cover 4, and a cleaning mechanism is also provided on the bottom surface of the cover 3, the cleaning mechanism includes a vertical pole 5, a sleeve 6, an electric telescopic cylinder 7, a turntable 9, a spray head 11 and a rotating unit, the vertical pole 5 is installed below the cover 3, the bottom end of the vertical pole 5 is fixedly installed with a sleeve 6, an electric telescopic cylinder 7 is installed in the sleeve 6, and a bracket 10 is fixedly installed on the sleeve 6, the electric telescopic cylinder 7 is rotatably set and driven by a micro motor 8 arranged outside the sleeve 6, the telescopic end of the electric telescopic cylinder 7 is also fixedly installed with a turntable 9, and a soft brush 12 is installed on the side of the turntable 9, the spray head The head 11 is fixedly mounted on the bracket 10, and the nozzle 11 is tilted. A connecting pipe 19 is installed at one end of the nozzle 11. The connecting pipe 19 passes through the vertical pole 5 and is connected to the liquid supply assembly (not shown in the figure) provided in the cover 3. The rotating unit is used to provide power for the vertical pole 5 to rotate around the protective cover 4. By setting a cleaning mechanism, the rotating unit in the cleaning mechanism drives the vertical pole 5 to rotate before and after the lens of the camera 2. The liquid supply assembly in the cover 3 transports cleaning liquid to the connecting pipe 19, and atomizes and sprays it onto the lens of the camera 2 from the nozzle 11. Subsequently, the electric telescopic cylinder 7 controls the turntable 9 to approach the lens of the camera 2. With the operation of the micro motor 8, the lens of the camera 2 can be cleaned to avoid impurities adhering to the front of the lens and causing blurred photography, thereby ensuring the smooth use of the inspection device.

[0020] Specifically, the rotating unit includes an outer ring gear 13 rotatably mounted on the bottom surface of the cover shell 3 and a driving gear 14 meshing with the outer ring gear 13 . The vertical rod 5 is fixedly mounted on the bottom surface of the outer ring gear 13 . The driving gear 14 is driven by a first servo motor 15 arranged in the cover shell 3 .

[0021] Preferably, the soft brush 12 is mounted on the turntable 9 by Velcro and can be disassembled. With this arrangement, after a camera 2 lens cleaning operation is performed, the dirty soft brush 12 can be torn off and replaced with a new soft brush 12, thereby avoiding the phenomenon that stains on the soft brush 12 cause secondary contamination to the lens.

[0022] Example 2

[0023] This embodiment is improved on the basis of embodiment 1, specifically:

[0024] See also Figure 2 and Figure 4The camera 2 is rotatably mounted in the protective cover 4 via a rotating shaft 16. The end of the rotating shaft 16 that passes through the cover 3 is transmission-connected to a second servo motor 18 disposed in the cover 3 via a bevel gear set 17. By rotatably mounting the camera 2 in the protective cover 4, when the camera 2 is not working, the lens of the camera 2 can be rotated to the inside of the cover 3 by controlling the second servo motor 18, thereby avoiding damage to the lens of the camera 2 due to prolonged exposure to the outside, thereby increasing the service life of the camera 2.
