Description

Technical Field

[0001] The utility model relates to the technical field of power facility protection, in particular to a tree clearing device under an overhead line. Background Art

[0002] The branches of the trees below the overhead lines are too tall, and the branches are in close contact with the cables. When encountering strong winds, the swaying of the branches will cause close friction contact with the cables, resulting in increased wear on the cable surface, reducing the service life of the cables and causing the cables to enter the replacement period ahead of time. The current solution is to use lifting equipment to transport personnel and cutting equipment to a high place to cut the branches. The lifting equipment is large in size, inconvenient to use and move, and has a high cost of use. In addition, there are also safety hazards for personnel working at heights. If a long-pole cutting device is used for remote cutting, the defects of the long-pole cutting device are: limited cutting distance; the long-pole cutting device is controlled by manpower during use, which has a high labor intensity and the pole body is prone to bending, and it is in urgent need of improvement. Therefore, we propose a tree cleaning device below overhead lines. Utility Model Content
