Description

Intelligent long-life audio bird repellent

technical field

The utility model relates to a bird repelling device for an electric tower pole, in particular to an intelligent long-life audio frequency bird repelling device.

Background technique

With the continuous improvement of the natural environment, people and animals are increasingly able to live in harmony. There are bird's nests on some power equipment, such as transformers and substation structures, power transmission and distribution line towers, and customer electricity meter boxes, which pose a threat to the safe and stable operation of power facilities. Some birds build their nests above the composite insulators of transmission lines, and the bird droppings fall on the surface of the composite insulators, which is easy to cause pollution. Especially in rainy and snowy weather, bird's nests on transformers and distribution lines can easily cause phase-to-phase short circuits or ground faults in power equipment, causing equipment trips and even fires, endangering the safety of power equipment and lines.

In order to eliminate the impact of the bird's nest, various power grid companies have adopted various methods. For example, windmill-type bird repellents, anti-bird thorns, anti-bird ridges and other methods are used to block the nesting position of birds and disturb their nesting. However, because birds are already familiar with such methods, the effect of repelling birds cannot be guaranteed. At present, the ultrasonic method is the most widely used and effective way to drive birds away. It is suitable for power system transmission lines and substations. The ultrasonic waves emitted can deteriorate the living environment of birds and drive them away from towers to build nests, so as to prevent bird damage and ensure safety.

Ultrasonic bird repellers currently on the market have the following deficiencies: 1. The battery is continuously discharged at any temperature, resulting in the need to replace the battery in about three years, which cannot guarantee long-term use; Ultrasonic organisms produce ecological damage; 3. The volume is large, not suitable for installation of distribution lines; 4. The settings are too complicated, and the requirements for installation users are high; 5. For field installation needs, the waterproof requirements are not up to standard; 6. The price is relatively high High, generally tens of thousands of yuan.
