High-voltage transmission line pole and tower multi-mode bird repelling device

Abstract

The invention discloses a high-voltage transmission line pole and tower multi-mode bird repelling device which comprises a base, a lower chamber located above the base, and a cover body matched with the lower chamber. Compared with the prior art, the overall concept is to provide the bird repelling device which has an immediate effect when birds stay, and sufficient frights are given to the birds so as to repel the birds; a wind cover faces a wind inlet all the time through a rotating bearing, when the birds stay on a horizontal connecting part, the tail end of the horizontal connecting part sinks, the aim of primarily frightening the birds is realized, if the birds do not leave, a lower connecting part pulls a box body, a check switch blocks an exhaust channel, the box body is gradually disengaged, the two side walls of the box body are lifted up to be flush with a vent hole, secondary frightening and repelling are conducted with the aid of an air outlet and the whistling of the air outlet, and a bird repelling agent in a groove is dispersed out of the device for tertiary repelling operation. The bird repelling device is more reasonable to use; conventional bird repelling operation is conducted with the aid of bird repelling barbs and reflectors on the device.

Description

technical field [0001] The invention relates to the technical field of bird repelling devices, in particular to a multi-mode bird repelling device for poles and towers of high-voltage transmission lines. 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, ...

Problems solved by technology

[0003] The currently used bird repellents mainly include windmill type, 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. However, most of the existing bird repellent devices are located It is relatively fixed, and the bird repelling method adopted cannot play a sufficient scaring effect. If the windmill rotation is too single and long-lasting, it will form the habit of birds over time. For example, the application number CN201510825364.8 discloses a method for power transmission The windmill type bird repelling device for the line, this invention mainly uses the windmill assembly fixed on it to realize the bird repelling function, its patented technology has a single bird repelling function when repelling birds, and the scope of action is small, the focus is on transmission line towers The frightening degree of the birds on the site is not high, and the problem of the retention of birds cannot be solved over time
