High-speed rail overhead contact lines carry high-voltage electricity, and twigs, thin wires, or even plastic ropes picked up from the ground—if dropped onto critical parts of the system—can easily cause a short circuit and trip the circuit breaker. Imagine a high-speed train packed with passengers suddenly losing power and coming to a halt because of a single thin wire—what a huge safety hazard that would be! Not to mention that bird nests can interfere with signal reception, and birds may even collide with high-speed trains while returning to their nests. To deter birds, railway authorities have tried many methods, and now, a new solution has been deployed! It is the Solar-Powered Catenary Bird Deterrent (ZQN-TL-DX) from Shenzhen Zhenqu Bird Technology.
The solar-powered overhead contact line bird repeller relies not on “brute force,” but on “smart tactics.” We’ve equipped it with a highly sensitive radar detection system; as soon as a bird flaps its wings and approaches the protected area, the radar instantly detects the signal. Then comes the main event. The device immediately activates its directional acoustic bird deterrent function. Through its built-in high-definition speaker, it emits bursts of powerful, penetrating sound waves. These sound waves have frequencies ranging from 2 kHz to 25 kHz, with a sound pressure level exceeding 120 decibels.
What does this mean? It’s like someone suddenly striking a gong right next to your ear—while it doesn’t cause any physical harm to the birds, the sheer intensity of the sound is enough to make them perceive the area as extremely dangerous and prompt them to evacuate immediately. Moreover, this sound is directed and precisely targeted, so it doesn’t cause excessive noise pollution in the surrounding environment.
Smart birds sometimes adapt to their environment, and if they hear the same sound over and over, they may stop being afraid of it. However, the genuine solar-powered overhead line bird repeller not only emits strong sound waves but also mimics the sounds of natural predators. It is programmed with a variety of sounds that birds fear most: the screeches of predators like eagles, the crackling of firecrackers, and even the alarm calls of their own kind when in danger. These sounds switch randomly, keeping the birds guessing and forcing them to stay well away.
Along railway lines in remote, rural areas, power supply is a major challenge. The solar-powered overhead line bird deterrent utilizes the ideal combination of “solar panels and rechargeable batteries.” As long as there is sunlight, it can recharge itself, eliminating the need for any additional power lines.
For hardworking railway maintenance workers, operating the solar-powered overhead contact line bird repeller is extremely simple. Once installed, all it takes is a gentle press of the remote control; when the operation indicator light turns on, the device will first emit a continuous acoustic signal for about 3 minutes, after which it will enter smart standby mode.
