Fan blade double-pressure conduction mechanism and high-voltage line tower bird repelling mechanism utilizing same

Abstract

The invention discloses a bird repelling device for a high-voltage power transmission line tower. The bird repelling device comprises an outer sleeve, a supporting rod connected with the outer wall ofthe outer sleeve, a hollow pipe arranged inside the outer sleeve and a fan blade assembly and a spring assembly located on one side of the outer sleeve. Compared with the prior art, the bird repelling device is simple in structure, utilizes the fan blade assembly to convert wind energy into kinetic energy, achieves effective energy transfer, the fan blade assembly is driven by wind to drive the spring assembly to compress, a conduction mechanism wholly moves to the right, so that the conversion of wind energy to kinetic energy is achieved, meanwhile an air outlet at the tail end of the hollowtube is matched with a ventilation channel of a supporting cylinder body, the transmission of the wind energy is achieved, and when the wind energy is transferred into an object placing cavity, a flip cover is blown to be opened to release a bird repellent component therein.

Description

Technical field [0001] The invention relates to the technical field of bird repellent devices, in particular to a fan blade dual pressure transmission mechanism and a high-voltage line tower bird repellent mechanism using the same. Background technique [0002] In recent years, the ecological environment has improved and human awareness of wildlife protection has increased, and bird activities have become more frequent. When birds defecate, build nests, fly, bird pecks and other activities on the transmission line, the excreted bird droppings form a conductive channel, which may cause the air gap of the tower to break down, and the insulator may also have flashover problems. Big Bird 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 1,867 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 number o...

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. Most of the existing bird repellent devices have relatively Complex, relatively single function, single function of bird repelling equipment, small range of action, not very frightening to birds on transmission line towers, unable to solve the problem of bird retention over time
