A bird repelling device inside a high-voltage line tower

Abstract

The invention discloses a bird repelling apparatus in a high-voltage wire tower. Compared with the prior art, the apparatus provided by the invention has a simple structure and is suitable for being installed in the high-voltage wire tower to drive birds on a tower body of the high-voltage wire tower. An overall conception of the apparatus is that reflective lenses installed on the exterior of a spherical cover are adopted to reflect sunlight to repel the birds on the tower body, the reflective lenses are deflected because of centrifugal force and air flowing generated by rotation of the spherical cover, so that all-directional illumination of different angles in the tower body can be realized, and finally bird repelling is realized; and in order to achieve a better bird repelling effect,a reflective device can be additionally arranged at the bottom of the high-voltage wire tower to illuminate a backlight surface of the bird repelling apparatus, and therefore the better bird repellingeffect is achieved. The apparatus provided by the invention has the advantages of reasonable design, a simple structure, long service life and an obvious bird repelling effect, and can effectively prevent activities of the birds on the tower body.

Description

Technical field: [0001] The invention belongs to a bird-repelling device for a high-voltage line tower, in particular to a 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 been increasi...

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
