CN203352054U - Foreign matter removing apparatus of power transmission line - Google Patents

Abstract

The utility model relates to the technical field of maintenance of high-voltage power transmission line, specifically to a foreign matter removing apparatus of a power transmission line. Foreign matters, such as kites, mulch films, and plastic cloths, may be frequently blown and dropped onto a grounding wire of the overhead power transmission line. If the foreign matters are not removed as soon as possible, accidents, such as short-circuit and trip-out, may occur in the case of rain and thus the safe operation of the power transmission line may be threatened directly. The foreign matter removing apparatus is composed of three parts, i.e., a telescopic insulating rod, a connecting head, and a cutter head, wherein the two ends of the connecting head are internally provided with inner screw threads; one end of the telescopic insulating rod and one end of a supporting rod connected with the cutter head are both provided with external screw threads; the telescopic insulating rod and the supporting rod connected with the cutter head are connected through the connecting head; and the cutter head is formed by two curved knives, wherein the knife edges of the two curved knives are opposite to each other, the knife handles of the two curved knives are connected horizontally, and the blades of the two curved knives are located in the inner side of the two curved knives. During the operation of the foreign matter removing apparatus, neither power cutting nor potential entering is needed. The removing work can be completed through the operation from the ground.

Description

A foreign matter removal device for transmission lines

technical field

The utility model relates to the technical field of maintenance of high-voltage transmission lines, in particular to a foreign object removal device for transmission lines.

Background technique

Transmission lines have been operating in a natural environment for a long time. During spring and autumn and windy weather, foreign objects such as kites, mulch, and plastic sheets are often scraped off on the ground wires of overhead transmission lines. If they are not removed as soon as possible, short circuits will occur in case of rain. Accidents such as tripping directly threaten the safe operation of transmission lines. Most of the foreign objects on the hanging wire are tightly wound on the ground wire and are not easy to fall off. Although some conventional tools (such as sickle-type cutter heads) can also be removed, the work efficiency is low, time-consuming and laborious, so it is necessary to innovate tools to solve the above problems.

Contents of the invention

The purpose of the utility model is to provide a foreign matter removal device for power transmission lines, which can quickly and labor-savingly remove foreign matter.

The technical scheme of the utility model is that the transmission line foreign matter removal device is composed of three parts: a telescopic insulating rod, a connecting head, and a cutter head; There are external threads; the telescopic insulating rod and the support rod connecting the cutter head are connected through the connecting head; the cutter head part is a machete with two blades facing each other and the handle ends are connected horizontally.

Further, the cutting edge of the cutter head is located inside the machete.

The utility model has the advantage that it does not need to cut off the power or enter the potential during operation, and the removal work can be completed on the cross arm of the pole tower (on the ground). The tool has the advantages of low cost, simple and convenient installation and use, ensures the safety of maintenance personnel, high removal work efficiency, and saves manpower and material resources.

Description of drawings

Fig. 1 is a schematic diagram of a knife for removing foreign matter from a power transmission line;

Figure 2 is a schematic diagram of the cutter head.

Detailed ways

In the figure: 1. Telescopic insulating rod, 2. Connecting head, 3. Cutter head, 4. Blade.

As can be seen from Fig. 1 and Fig. 2, the utility model is composed of three parts: a telescopic insulating rod 1, a connecting head 2 and a cutter head 3; both ends of the connecting head are provided with internal threads, and one end of the telescopic insulating rod and a support rod connecting the cutter head Both are equipped with external threads; the telescopic insulating rod 1 and the support rod connecting the cutter head are connected to the cutter head through the connector 2. The part of the cutter head is two machetes with opposite edges and horizontally connected handle ends; the blade 4 of the cutter head is located on the machete inside.

When in use, the insulating operating rod 1 is connected and fixed with the cutter head 3 through the connector 2, and the set of tools is assembled. When working, the operator holds an insulated operating rod on the pole tower (or on the ground), touches the foreign matter wrapped around the ground wire with the cutter head, and separates and removes the foreign matter from the ground wire by means of push-pull cutting, winding and pulling, etc. , retract the insulating operating rod, disassemble the tool, and complete all operations.
