The power transmission line foreign matter cleaning device is scientific in design, simple in structure, low in cost, easy to manufacture, simple in operation, high in safety and great in foreign matter cleaning effect so that large amount of manpower, material resources and financial resources are saved, and work efficiency of workers is greatly enhanced.

Description

Transmission line foreign matter cleaning device

technical field

The utility model relates to an electric power auxiliary tool, in particular to a foreign matter cleaning device for transmission lines.

Background technique

Transmission lines are generally erected outdoors. In windy weather, lighter or larger objects that are prone to wind are easily blown up and hung on the transmission line. This will cause the following hazards: 1. ) Since these foreign objects generally do not have sufficient insulation, it may cause discharge between the wires to the ground and between wires and wires, resulting in line tripping; 2) In cloudy and rainy days, these foreign objects will also short-circuit the transmission line, causing electricity hazards; 3 ) These foreign objects hanging on the wire and rubbing against the wire may also cause damage to the wire and threaten the safety of the line.

After encountering the above situation, the power transmission maintenance department needs to remove the foreign matter hanging on the wire as soon as possible to ensure the safe operation of the line. Generally, the simple solution is to use insulating ropes to clean up foreign objects, but this cleaning method is inefficient, difficult to control, and has potential safety hazards; and a more advanced solution is to use some special equipment, such as using wires for foreign objects The remote control wire clamp crawling incineration machine, this kind of special equipment is thoroughly cleaned and safe, but it also has the disadvantages of large size, heavy weight, high cost, and inconvenient transportation.

Contents of the invention

The purpose of the utility model is to provide a foreign matter cleaning device for power transmission lines in order to solve the above-mentioned problems in the prior art.

The utility model is achieved through the following technical solutions:

A transmission line foreign body cleaning device, comprising two identical pinch tubes with a semicircular cross-section, the two pinch tubes are butted together to form a circular tube; one side of the two pinch tubes is hinged by a hinge shaft, A torsion spring is installed on the hinge shaft, and under the action of the elastic force of the torsion spring, the butt edges on the other side of the two clamp tubes are tightly butted together; There is a row of rollers installed on the inner wall, and the inner wall of the pinch tube is evenly distributed with several conical points between the rollers at both ends, and the height of the conical points is lower than the height of the rollers; there is a handle on the outer wall of the pinch tube, the handle There is an insulating rope on the top. In the above structure, the height of the cone tip is lower than that of the roller, that is, the distance from the tip of the cone to the inner wall of the pinch tube is smaller than the distance from the outermost end of the roller to the inner wall of the pinch tube, so that when the pinch tube is sleeved on the transmission line When it is on, the transmission line can only contact the roller, but the cone tip cannot touch the transmission line, which effectively avoids the problem that the transmission line is damaged by the cone tip when removing foreign objects.

When in use, the other side of the two semi-circular pinch tubes in the utility model are opened, and the transmission line is clamped in the circular tube composed of the two pinch tubes. The worker only needs to pull the insulating rope to close the utility model. The new device can be pulled along the power transmission line. When the foreign matter on the power transmission line enters the device of the utility model, the conical tip inside will catch the foreign matter, thereby cleaning the foreign matter on the power transmission line.

Further, the row of rollers includes several rollers, and each roller is fixed on the inner wall of the pinch tube through a connecting ear plate, and the axes of the rollers and the axis of the pinch tube are arranged perpendicular to each other.

The utility model has the advantages of scientific design, simple structure, low cost, easy manufacture, simple operation, high safety, good effect of removing foreign matter, saves a lot of manpower, material and financial resources, and greatly improves the work efficiency of workers.
