A kind of bird repelling method and bird repelling device based on ultrasonic

Abstract

The invention discloses a bird repelling method and a bird repelling device based on ultrasonic waves. The bird repelling method generates ultrasonic waves of various frequencies by a frequency-adjustable ultrasonic generating module inside a central processing module, and utilizes the difference between the bird-free duration t and the test duration T. The ratio characterizes the bird repelling effect of each frequency of ultrasonic waves, and the ultrasonic bird repelling effect test of each frequency is carried out, and the most suitable ultrasonic frequency for bird repelling is selected for bird repelling, so as to satisfy the bird repelling effect of different birds in various regions and periods. , to improve the efficiency of bird repelling. The bird repelling device includes a central processing module, an ultrasonic generating module, an ultrasonic speaker, a detection module, and a clock module; the ultrasonic generating module is an ultrasonic generating module with adjustable frequency, which emits ultrasonic waves of various frequencies to improve the bird repelling effect. .

Description

technical field [0001] The invention relates to the technical field of bird repelling by towers, and in particular, to a bird repelling method and a bird repelling device based on ultrasonic waves. Background technique [0002] Birds like to build their nests on iron towers during the breeding season, and their nesting materials include branches, dead vines, waste cotton thread, and even iron wire. Falling of these materials could short-circuit several pieces of the jar, causing the circuit to trip. All kinds of big birds like to fall on the cross arm of the center line of the tower after foraging. A large amount of feces is discharged during rest, which will pollute the porcelain bottle, reduce the insulation strength of the porcelain bottle string, and cause the circuit to trip. [0003] The bird damage fault points on the line are all on the steel tower with pull wire or steel, and most of them are on the center line porcelain bottle string of the straight iron tower an...

AI Technical Summary

Problems solved by technology

However, for different regions and different seasons in the same region, the types of birds that nest or stay on transmission towers and transmission lines are different, and different types of birds have different tolerances to the same ultrasonic frequency

And in the same area, if a certain frequency of ultrasonic waves is used to repel birds for a long time, the birds in this area will also develop tolerance to it, and the effect of repelling birds will decline.
