Processing mechanism for power supply line

The invention belongs to the technical field of power grid maintenance, and particularly discloses a processing mechanism for a power supply circuit, and the processing mechanism comprises a bottom plate, an upper cleaning cylinder, a lower cleaning cylinder, and a mounting plate which is fixedly connected to the bottom of the bottom plate and is used for being connected with the upper part of an unmanned aerial vehicle. Lower supporting seats are fixedly connected to the two sides of the top of the bottom plate, lower driving rollers are rotationally connected to the inner sides of the lower supporting seats, upper supporting seats are arranged above the lower supporting seats, upper driving rollers are rotationally connected to the inner sides of the upper supporting seats, and driving mechanisms used for driving the two upper driving rollers to rotate are arranged on the side walls of the upper supporting seats. Through mutual cooperation of the structures, the foreign matter processing equipment can be qu
