A self-swinging bird repelling device inside a high-voltage line tower

Abstract

The invention discloses a self-swing type bird repelling device inside a high-voltage line tower, which includes: a base, a swing bar, a first swing assembly, and a second swing assembly. Compared with the prior art, the invention has a simple structure and is suitable for use inside a high-voltage line tower It is installed to drive away birds on the tower body of the high-voltage line tower. The general idea of ​​the invention is to use the first and second swing components to swing the device as a whole to drive birds. When the device is stationary, the overall weight of the second swing component pulls the telescopic spring Stretching, with the movement of the ride, it can provide a circumferential rotational force for the second swing assembly when it rotates and provide an upward lift force when it moves to the bottom of the moving plate, and the circumferential rotational force promotes the second swing assembly on the line tower The interior rotates in a circumferential direction, and the lifting force causes the telescopic spring to contract and pull the second swinging component, resulting in vertical movement, which makes the overall operation of the device disorderly and disorderly. At the same time, the swing rod can enhance the overall amplitude of the device, and the bird repelling range is larger 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
