A multifunctional integrated bird repellent

Abstract

The invention provides a multifunctional integrated bird repellent device. The device is mainly composed of an electric power module, a processor, a radar detection module, an ultrasonic-wave module and a voice module. The radar detection module comprises a microwave oscillator, a wave filter, a transmitting antenna, a receiving antenna, a frequency mixer and a wave detector, wherein the transmitting antenna is connected with the microwave oscillator via the wave filter and can outwardly and directionally transmit oscillating microwave signal; the receiving antenna matched with the transmitting antenna can receive reflected waves and is connected with the frequency mixer which receives oscillating waves via the wave filter; and the reflected waves and the oscillating waves, after hybrid detection via the wave detector connected with the frequency mixer, form a low-frequency signal which can reflect moving of an object and is transmitted to the connected processor. The processor is also connected with the ultrasonic-wave module and the voice module, wherein the ultrasonic-wave module is an ultrasonic-wave circuit which is mainly composed of a phase inverter and an ultrasonic-wave transmitting transducer. The multifunctional integrated bird repellent device provided by the invention has the advantages of reasonable structure, convenient use, good bird-repelling effect, and reliable usage performance.

Description

technical field [0001] The invention relates to a multifunctional comprehensive bird repelling device, which belongs to the technical field of bird repelling for power circuit safety. Background technique [0002] Transmission lines are an important part of the power grid. Transmission lines are responsible for the long-distance transmission of high voltage. Therefore, the safety of transmission lines directly affects the reliability of power supply for users and the economic benefits of power supply companies. But at present, a major hidden danger that affects the safe operation of transmission lines is bird damage accidents. According to survey statistics, about 25% of power system failures are caused by bird damage every year. Bird damage includes birds pecking at insulators, birds building nests, excessively long straw, etc. causing the line to discharge to the tower, causing line tripping, or bird droppings, causing insulators or other equipment obstacles, resulting in ...

Problems solved by technology

However, there are some problems in these methods, such as installing metal anti-bird thorns, which brings a lot of trouble to line maintenance; manual removal of bird nests takes time, effort and money; existing electronic bird repellents mainly rely on means such as emitting ultrasonic waves or voice to drive away birds, but Regardless of whether there are birds approaching, they will release ultrasonic waves and popping sounds at regular intervals, which will not only generate noise pollution, but also birds will gradually adapt to the sound of the bird repellent, reducing the repelling effect of the bird repellent
