I. Demand Analysis:

Birds tend to build nests on railway catenary poles, which affects railway facilities. During the nest-building process, birds bring materials such as iron wires and damp branches, which can easily cause short circuits in power supply equipment, leading to catenary tripping. This significantly impacts power supply safety and the normal operation of trains. The ZQN-TL-BXG bird repellent for electrified railway catenaries can effectively drive away birds, reduce bird-related incidents, and maintain railway operational safety.

II. Working Principle:

The electrified railway catenary bird repellent is designed based on the windmill principle, using wind as its power source. When a breeze blows, it starts quickly and rotates continuously at 15 to 20 revolutions per minute. This rotation itself prevents birds from approaching, serving as a bird deterrent.

Additionally, during rotation, the device creates a scattered light area around it through the principle of optical reflection, producing a strong reflective effect. Bird eyes are sensitive to light, so when birds approach the device area, the rotation and intense light exposure or reflection immediately alert them, preventing them from nearing the catenary area and causing them to actively move away.

The device comes in two sizes, small and large, to meet different needs: the small size is 20cm, and the large size is 40cm.

III. Functional Features:

1. Made of high-quality stainless steel material, corrosion-resistant, lightweight, and easy to start with a breeze.

2. The wind scoop is designed in the shape of a windmill to assist power, increasing the rotation power and speed of the bird repellent.

3. The rotating shaft is designed with a damping coefficient, providing typhoon resistance to ensure the device does not rotate indefinitely, making it safe and reliable.

4. Both the base and the iron rod are coated with an anti-corrosion galvanized layer, ensuring durability and adaptability to various harsh environments.

5. 360-degree reflection angle with no blind spots. Easy to install, maintenance-free, and a lifespan of up to 10 years.
