[0001] The invention relates to the technical field of power grid lines, and in particular to a switch maintenance robot for long-distance power transmission lines. Background Art

[0002] High-voltage transmission lines are equipped with switchgear, such as circuit breakers and disconnectors. When inspecting and maintaining the switchgear, workers are required to operate at high altitudes, which is very dangerous. In the prior art, maintenance robots are used to inspect and maintain switchgear. However, the transmission lines may be covered with debris such as kites and plastic films. Traditional maintenance robots cannot clean up the debris, which affects the movement of the maintenance robots on the transmission lines.

[0003] Prior art CN116598948B discloses an intelligent robot for power grid transmission lines. By starting a second motor, the second motor drives a transmission wheel to rotate, and the transmission wheel drives the intelligent robot body to move outside the power grid transmission line, so that the inclined surfaces of the first card block and the second card block are inserted into the inside of the entangled debris. When the intelligent robot body moves, the first card block and the second card block spread out the entangled debris, and at the same time extend the cutting telescopic rod, and the cutting telescopic rod drives the first cutter to move downward, and the first cutter and the second cutter cut the entangled debris. In this way, the debris on the power grid transmission line can be spread out by the first card block and the second card block, and the first cutter and the second cutter cut the entangled debris outside the power grid transmission line, thereby cleaning the debris on the power grid transmission line and improving the efficiency of the operation of the intelligent robot on the power grid transmission line.
