Description

Power transmission line charged foreign matter shearing device

technical field

The utility model belongs to the technical field of electric power system auxiliary equipment, in particular to a cutting device for charged foreign matter of a power transmission line.

Background technique

With the increase in the number of transmission lines erected, the increase of human activities around the transmission lines, and the influence of bad weather, overhead transmission lines are often damaged by large foreign objects such as colorful balloons, kites, and propaganda banners hanging on them. Most of these foreign objects are located in the high-altitude part of the wire gear, which is very harmful. It is difficult for the operator to find or eliminate the above defects without entering the wire. Due to the limitation of the safety clearance of the operation, it cannot be carried out, and there is a great danger at the same time. If a power outage is required, the reliability of the power supply will be reduced.

Contents of the invention

In order to solve the above problems, the purpose of the utility model is to provide a power transmission line charged foreign matter shearing device.

In order to achieve the above purpose, the utility model provides a live foreign matter shearing device for transmission lines including an insulating rod, a fixed blade, a support rod, a pulley, a movable blade and an insulating rope; wherein the lower end of the fixed blade is fixed on the upper side of the insulating rod, The upper part is a saw blade, and the lower part is a scissors blade with a hook; the lower end of the support rod is fixed on the other side of the upper end of the insulating rod; the pulley is fixed on the lower surface of the support rod; the rear end of the movable blade is hinged on the upper end of the support rod, The front part is a scissors blade; one end of the insulating rope is held by the operator, the other end is fixed on the scissors blade at the front of the movable blade, and the middle part bypasses the pulley and the hinge point of the movable blade and the support rod.

The fixed blade is arc-shaped, and both sides of the upper saw blade are provided with serrations.

The connection between the insulating rod, the fixed blade and the support rod is detachable.

The utility model provides a cutting device for charged foreign objects on transmission lines, which can easily trim and remove light and thin cloth-like objects such as advertising cloth, ropes, and agricultural greenhouse plastic films hanging on the overhead transmission line by using the fixed blade and the movable blade on it. All kinds of foreign matter, and different grades of insulating rods and insulating ropes can be used according to different voltage levels to meet the requirements of various occasions.

Description of drawings

Fig. 1 is a schematic diagram of a shearing device for charged foreign matter of a power transmission line provided by the present invention.

Detailed ways

The power transmission line charged foreign matter shearing device provided by the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the live foreign body shearing device for transmission lines provided by the utility model includes an insulating rod 1, a fixed blade 2, a support rod 3, a pulley 4, a movable blade 5 and an insulating rope 6; Fixed on one side of the upper end of the insulating rod 1, the upper part is a saw blade, and the lower part is a scissors blade with a hook; the lower end of the support rod 3 is fixed on the other side of the upper end of the insulating rod 1; the pulley 4 is fixed on the lower surface of the support rod 3 The rear end of the movable blade 5 is hinged on the upper end of the support rod 3, and its front portion is a scissors blade; one end of the insulating rope 6 is held by the operator, and the other end is fixed on the scissors blade at the front portion of the movable blade 5, and the middle part walks around the pulley 4 And the hinge point of movable blade 5 and support bar 3.

The fixed blade 2 is arc-shaped, and both sides of the saw blade on the top are provided with sawtooth.

The connection between the insulating rod 1 and the fixed blade 2 and the support rod 3 is detachable.

When it is necessary to use the power transmission line live foreign matter shearing device provided by the utility model to trim and remove various foreign matter such as advertising cloth, ropes, and thin cloth-like objects such as plastic films in agricultural greenhouses hanging on the overhead transmission line, the staff can cut them according to the foreign matter. Select the insulating rod 1 and insulating rope 6 of different lengths according to the position, and then hold the insulating rod 1 high, so that the fixed blade 2 is close to the foreign matter to be removed, and then the saw or scissors on the fixed blade 2 can be used to cut off or pull If the foreign matter cannot be separated from the overhead transmission line, the movable blade 5 can be swung by pulling the lower end of the insulating rope 6, thereby cutting or breaking the foreign matter, thereby achieving the purpose of removing the foreign matter.
