A stable power supply is particularly vital for daily life and production. However, ensuring the safe operation of the power grid can sometimes be disrupted by bird activity. Birds are especially fond of nesting and resting on tall utility poles and transmission towers. Their droppings can easily cause "insulator flashover," leading to circuit breakers tripping and power outages. Additionally, bird nests themselves are constructed from various materials like branches and wire, which can potentially catch fire under certain conditions, posing a threat to the safety of transmission lines.
To address this issue, the power industry commonly installs bird repellents. Shenzhen Zhenquniao Technology's Multifunctional New-Generation Power Bird Repeller ZQN-DL-ZN2 primarily employs two methods to deter birds. The first utilizes ultrasonic waves, emitting high-frequency sound waves inaudible to humans that cause discomfort to birds, prompting them to voluntarily leave the area. This approach does not harm birds and is considered a relatively gentle deterrent.
The second method is acoustic bird deterrence. The device plays the calls of birds' natural predators, such as eagles, or sudden, loud noises like gong strikes or firecrackers. These sounds alert birds to perceived danger nearby, naturally discouraging them from approaching power facilities. Combining ultrasonic and acoustic deterrents prevents birds from adapting, thereby extending the effectiveness of bird control.
In addition to bird deterrence, the device also serves as a pedestrian warning system. Equipped with an RF radar system, it emits an audible alert and displays a prominent "High Voltage Danger" warning within a range of approximately 5 meters (adjustable distance) when someone approaches, reminding pedestrians to stay safe. For installation and power supply, it utilizes both solar panels and grid electricity, making it suitable for various outdoor environments. Installation is straightforward—it can be directly mounted on channel steel or suspended in an appropriate location, and is applicable for substations, towers, and other venues.
