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

Embodiment

[0016] 1. Radar detection,

[0017] The present invention utilizes Doppler radar sensor and discriminating circuit, is specially used in detecting the activity of bird, when detecting and analyzing that there is bird within the range of repelling bird, trigger voice circuit to generate explosive sound to drive away bird class leaves.

[0018] Doppler theory is based on time, when a radio wave hits an object as it travels, the wave reflects. The frequency of the reflected wave changes with the moving state of the object. If the position where the radio wave hits an object is fixed, the frequency of the reflected wave should be equal to the frequency of the emitted wave. If you move in the direction of emission, the reflected wave will be compressed, which means that the frequency of the reflected wave will increase. Conversely, when the object moves toward the direction of the principle emission, the frequency of the reflected wave will decrease accordingly, which is the Dop...

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 line 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 lin...
