Problems solved by technology

However, because the overhead transmission line is relatively high from the ground, it is difficult to clean it. Although engineering vehicles can be used to raise it to a certain height, it is also difficult due to live work. In addition, many lines are not on the roadside, even in the wild where vehicles are not easy to pass.
This brings difficulties to the cleaning of suspended foreign objects on overhead transmission lines

Abstract

The invention discloses a device for removing a suspended foreign body from an overhead transmission line. The device comprises a shell, wherein the shell is provided with two side plates and a connecting part which is used for connecting the two side plates; a rope fixing device is arranged on each side plate; a guide groove is formed between the two side plates; at least two guide wheels which are linearly distributed along the guide groove are arranged in the guide groove; the guide wheels are assembled on the two sides; and cutting devices which are opened and closed under the control of pulling ropes are arranged on parts of the shell, which are positioned at one or two ends of the guide groove. The device has the characteristics of convenience for carrying and convenience for use.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance equipment, in particular to a device for removing foreign objects suspended from overhead transmission lines. Background technique [0002] Due to human factors or natural factors and other reasons, there are often foreign objects hanging on the overhead transmission line. For example, when flying a kite near the transmission line, sometimes the kite will be entangled on the transmission line. Or get entangled with power lines due to wind blowing plastic bags etc. into the sky. When there are foreign objects entangled on the transmission line, it will cause a great safety hazard, especially the foreign objects are entangled on the high-voltage line. Suspended foreign objects on the transmission line pose a threat to the power system and personal safety. For this reason, it is necessary to immediately remove the hanging foreign matter on the transmission line to eliminate po...
