[0027] Among them, the extension mechanism 2 includes a multi-section electric push rod, which is fixedly installed on the bottom of the frame of the drone body 1 through angle irons. The rotating mechanism includes a hollow rotating platform, and the fixed part of the hollow rotating platform is fixedly installed on the piston rod end of the multi-section electric push rod. A first motor 19 for driving the rotating part of the hollow rotating platform to rotate is fixedly installed on the fixed part of the hollow rotating platform.

The laser rust removal gun 16 is fixedly installed on the support frame 14. A first camera 9 for monitoring the surrounding environment when the extension mechanism 2 drives the laser rust removal gun 16 to extend into the inner side of the transmission tower is fixedly installed on the frame of the drone body 1, and a second camera 18 for monitoring the rust removal part of the laser rust removal gun 16 is fixedly installed on the support frame 14.

[0028] By adopting the above technical solution, when it is necessary to perform rust removal on the inside of the transmission tower, the piston rod of the multi-section electric push rod is controlled to extend by operating the remote control handle, so that the laser rust removal gun 16 can be extended from the bottom of the frame of the drone body 1, and the surrounding environment when the piston rod of the multi-section electric push rod is extended is observed in real time by the first camera 9 to ensure that the laser rust removal gun 16 can be accurately sent to the inside of the transmission tower, and the laser rust removal gun 16 can be driven to rotate by controlling the forward and reverse rotation of the rotating shaft of the first motor 19, and the second camera 18 can be observed during the adjustment process to understand the direction of the laser rust removal gun 16 in real time, so that the laser rust removal gun 16 can be driven to accurately face the rusted part of the transmission tower, and then the laser rust removal gun 16 is started to perform rust removal on the rusted part of the transmission tower.

[0029] Specifically, a paint storage box 4 is fixedly installed on the top of the frame of the drone body 1, a liquid filling port 8 is provided on the top of the paint storage box 4, a sealing cap is threadedly installed on the liquid filling port 8, a charging pump 5 for pressurizing the inside of the paint storage box 4 is fixedly installed on the top of the paint storage box 4, a pressure switch 6 is fixedly installed inside the paint storage box 4, the charging pump 5 is controlled by the pressure switch 6, a solenoid valve 7 is installed at the lower end of one side of the paint storage box 4, the output port of the solenoid valve 7 is connected to a nozzle 15 through a delivery pipe 11, and the nozzle 15 is fixedly installed on the support frame 14.
