Use method of whistle type bird repelling device in high-voltage line tower

Abstract

The invention discloses a use method of a whistle type bird repelling device in a high-voltage line tower. The use method comprises three steps of mounting, whistle bird repelling and resetting. Compared with the prior art, the whistle type bird repelling device is simple in structure, and suitable for being mounted in the high-voltage line tower to repel birds on a tower body of the high-voltageline tower. According to the overall conception, fan blade assemblies are used for collecting wind power, when the wind power is large, the wind power blows rotating fan blades to the bottoms of the fan blade assemblies to abut against outer rings at telescopic tables, the telescopic tables drive vertical rods and blocking parts at telescopic mechanisms to move after being stressed so as to open first air inlets, and the wind power entering hollow pipes can be changed, so that adjustment of the volume at the first whistle position is achieved; and the wind power enters a second sleeve througha first sleeve and then drives a piston to contract, then a first air outlet and a second air outlet are opened according to the wind power, the sound volume is changed in sequence, and effective birdrepelling operation is carried out.

Description

Technical field: [0001] The invention belongs to a bird-repelling method of a high-voltage line tower, and in particular relates to a method for using a whistle-type 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 num...
