Overhead transmission line foreign body removal device

Abstract

The invention provides an overhead transmission line foreign body removing device which comprises an installation cabinet, a hanging plate, two roller wheels and a circuit assembly. The installation cabinet is provided with a traction hole group; the installation cabinet and the hanging plate are respectively provided with a hanging hole group; the two roller wheels are fixedly arranged between the upper end of the installation cabinet and the hanging plate; and the circuit assembly comprises a conductive support rod group fixedly arranged to the installation cabinet and the hanging plate, resistance wires fixedly arranged on the conductive support rod group and used for carrying out thermal cutting on foreign bodies on the transmission lines, a storage battery arranged in the installation cabinet and used for providing power for the resistance wires, a relay KA arranged in the installation cabinet and used for controlling the connection and disconnection of a power supply of the resistance wires, a remote control receiver arranged in the installation cabinet and used for controlling the action of the relay KA, and a handheld remote control emitter for sending an on / off command to the remote control receiver wirelessly. The overhead transmission line foreign body removing device is simple in structure, low in cost, easy to carry and convenient to use during operation, and capable of removing various foreign bodies on the power transmission lines through thermal cutting safely, quickly and thoroughly.

Description

technical field [0001] The invention relates to the technical field of live working tools for electric power transmission lines, in particular to a foreign object removal device for overhead power transmission lines. Background technique [0002] The power transmission line runs in the natural environment for a long time, and it is easy to entangle foreign objects, such as wind blowing and other reasons, such as agricultural greenhouse plastics, sunshade nets, braided belts, advertising cloth for advertising, kites and kite ropes and other foreign objects are entangled in the power transmission On the line, after these foreign objects are exposed to rain or moisture, the insulation performance is poor, and it is easy to cause accidents such as tripping and short circuit of the transmission line, which seriously affects the safety of power grid power supply. The traditional method of removing foreign matter on transmission lines is to hang the flying car on the transmission w...

Problems solved by technology

At present, there are usually two types of foreign matter removal devices for overhead transmission lines: one is the various cutting and pulling cutter heads set with an insulating operating rod and an insulating operating rod head. The operator holds the insulating operating rod and uses various The cutter head cuts and pulls the foreign matter on the line to remove the foreign matter, such as the authorized announcement number CN 202423996U, the authorized announcement number CN202034707, the application publication number CN 104064985A and other Chinese patent documents; the common disadvantage of this type of device is that the operation is time-consuming It is laborious and inefficient, and it is difficult to deal with foreign matter on the line that is far away from the tower; the other type is to install various cutter head-type rescue tools on the device that can move on the transmission line to remove foreign matter. The publication number is CN103441448A, the application publication number is CN 103944108A and other Chinese patent documents; it uses a device that can move on the transmission line to solve the problem that the foreign matter on the line that is far away from the tower is difficult to deal with in the first type of device. However, this type of device still relies on various cutter heads to remove foreign matter on the line by cutting, and there are still problems such as the first type of device is not efficient in removing foreign matter, and the effect is not good.
