Bird repelling device for high-voltage power transmission line towers

Abstract

The invention discloses a bird repelling device for high-voltage power transmission line towers. The bird repelling device comprises a connecting rod, a plurality of air supply mechanisms, whistle mechanisms, a blade mechanism and connecting bases. The air supply mechanisms, the whistle mechanisms and the blade mechanism are erected on the upper portion of the connecting rod, the connecting basesare fixed to the bottom of the connecting rod, air force can be provided by the air supply mechanisms to push switch assemblies to start whistles, the switch assemblies are positioned at the connecting rod, air outlets are matched with one another, and accordingly the purpose of repelling birds can be ultimately achieved by the aid of different degrees of sound intensity and diversified combinations. Compared with the prior art, the bird repelling device has the advantages that the bird repelling device is simple in structure, diversified bird repelling modes are combined with one another, accordingly, the purpose of repelling the birds can be achieved, the birds can be effectively prevented from nesting or retaining on power transmission lines, the operational reliability of the power transmission lines can be improved, and bird damage accidents of the power transmission lines can be prevented.

Description

technical field [0001] The invention relates to the technical field of bird repelling devices, in particular to a bird repelling device for high-voltage transmission line towers. Background technique [0002] In recent years, with the improvement of the ecological environment and the enhancement of human's awareness of wildlife protection, bird activities have become more frequent. When birds defecate, build nests, fly, pecking and other activities on the transmission line, the excretion of bird droppings forms a conductive channel, which may cause the breakdown of the air gap between the tower and the tower, and the insulator may also have problems such as flashover. Big birds will directly cause short-circuit faults, which will seriously affect the safe and stable operation of transmission lines. From 2005 to 2014, a total of 1867 bird damage trips occurred on the 110(66)kV and above lines of the State Grid Corporation of China, accounting for 7.1% of the total 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.
