Automatic bird-repellent device used for high-voltage transmission line poles and towers

Abstract

The invention discloses an automatic bird-repellent device used for high-voltage transmission line poles and towers. Compared with the prior art, wind force is utilized in the device for driving rotating blades to do up-and-down reciprocating motion on a bearing shaft, when wind force is small, the rotating blades only can rotate on a limiting baffle, when wind force becomes large, by means of thespecial structures of the rotating blades, lift force is generated, and the rotating blades thus do the ascending motion on the bearing shaft and thus return to the limiting baffle when wind force isreduced; the length of the bearing shaft can be freely controlled, and according to the heights of the transmission line poles and towers and places where birds are likely to nest, wiremen can install the bird-repellent device in a target mode; light reflection components are arranged on the surfaces of a connection rod and a wind hood, the bird-repellent range of the device is increased, and thedevice is reasonable in structural design, easy to install, long in service life and good in bird repelling effect.

Description

technical field [0001] The invention relates to the technical field of bird repelling devices, in particular to an automatic 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. For example, the application number is CN201510825364.8, which discloses a windmill type bird repelling device for power transmission lines. This invention mainly uses the windmill assembly fixed on it to realize the bird repelling function. At present, the bird repelling function of the device is single, and the range of action is small. The degree of frightening the birds on the transmission line tower is not high, and the problem of the retention of birds cannot be solved over time.
