Technical Field

[0001] The utility model belongs to the technical field of electric power maintenance facilities, and in particular relates to a foreign matter removing device for a power transmission line. Background Art

[0002] During the construction of power transmission lines, foreign objects such as plastic sheets and ribbons are often blown up by the wind and hung on wires or poles. If not removed in time, they can easily cause short circuits and other faults. Therefore, eliminating foreign objects entangled in transmission lines as soon as possible has become one of the important means to reduce the occurrence of power accidents.

[0003] The existing transmission line foreign body removal device can only work at a certain height, resulting in low adaptability and inconvenient operation when used in transmission lines at different heights. For this reason, we propose a transmission line foreign body removal device. Utility Model Content
