Self-swinging bird repelling device in high-voltage wire tower

Abstract

The invention discloses a self-swinging bird repelling device in a high-voltage wire tower. The self-swinging bird repelling device in the high-voltage wire tower comprises a base, a swing rod, a first rocking assembly and a second rocking assembly. Compared with the prior art, the self-swinging bird repelling device in the high-voltage wire tower has simple structure, and is suitable for being installed inside a high-voltage wire tower to repel birds on the tower body of the high-voltage wire tower. According to the general concept of the invention, the first rocking assembly and the second rocking assembly are used to carry out rocking bird repelling operation on the device, and when the device is stationary, the overall weight of the second rocking assembly pulls an extension spring toexpand. With the movement of a wind catching device, circumferential rotating force can be provided for the second rocking assembly when the wind catching device rotates, when the wind catching devicemoves to the bottom of an upper moving plate, a upward lifting force is provided for the upper moving plate, by the circumferential rotating force, the second rocking assembly circumferentially rotates in the wire tower, by the lifting force, the extension spring shrinks and lifts the second rocking assembly to generate movement in the vertical direction, the whole device runs irregularly, meanwhile, the amplitude of the whole can be enhanced by the swing rod, the bird repelling range is large, and the effect is remarkable.

Description

Technical field: [0001] The invention belongs to a bird-repelling device for a high-voltage line tower, in particular to a self-swinging bird-repelling device inside a high-voltage line tower. Background technique: [0002] In recent years, with the improvement of the ecological environment and the enhancement of human awareness of wildlife protection, bird activities have become more frequent. When birds defecate, nest, fly, peck and other activities on the transmission line, the excreted bird droppings form a conductive channel, which may cause the air gap breakdown of the tower, and the insulator may also have flashover and other problems. A large bird will directly cause a short circuit fault, seriously affecting the safe and stable operation of the transmission line. From 2005 to 2014, a total of 1867 trips due to bird damage occurred on 110 (66) kV and above lines of the State Grid Corporation of China, accounting for 7.1% of the total number of line trips, and it has...

Problems solved by technology

[0003] As the main support for high-voltage lines, high-voltage line towers are suitable for being used as the first choice for bird's nests, which increases the safety hazards of high-voltage line towers. Therefore, the anti-bird's nest structure for the tower body structure of high-voltage line towers is also crucial Importantly, the currently used bird repellents mainly include windmill, sound, ultrasonic and other bird repellents. In order to strengthen the frightening effect on birds, there are also some that use windmills to make crackling noises when they rotate to scare birds. For example, the application number is CN201510825364.8 A windmill-type bird-repelling device for power transmission lines is disclosed. This invention mainly uses the windmill assembly fixed on it to realize the bird-repelling function. The patented technology has a single bird-repelling function and a small range of action when repelling birds. , it can only be erected near the cross arm, and cannot effectively drive away the birds in the tower structure, so there is an urgent need for a bird repelling device that can be installed on the tower body of the high-voltage line tower
