Bird's nest is a rare thing in nature, but when it is constructed in the railroad contact network, it can cause a lot of trouble.
I don't know if you have noticed that many birds like to build their nests and roosts in electric poles, contact network pillars and hard crossbeams along the railroad, including some large and rare birds. These places are firmly rooted, won't shake and have high stability, which meets the nesting site requirements of birds. However, if the bird's nest contains metal objects, it will easily lead to short connection between the charged part and the grounding body, resulting in transient short circuit and causing tripping, which seriously threatens the stable and safe operation of high-speed rail vehicles.
In order to discover and remove these potential safety hazards in time, the equipment maintenance personnel need to conduct regular inspections and remove the bird's nests that have been built. However, such a task is undoubtedly a difficult challenge under the vast land of the depot and several kilometers of contact network mileage.
To cope with the threat of bird's nest to the subway contact network, as well as to reduce the workload of maintenance personnel, the railway-specific directional acoustic wave bird repeller ZQN-TL-DX fully integrated directional acoustic wave acoustic pressure technology and radar detection technology, the use of radar detection devices to actively detect the proximity of birds, once the detection of birds that is, the directional acoustic wave will be activated to automatically complete the work of bird repellent. Through the embedded speaker, it can transmit high-definition strong sound waves over a long distance to disturb and stimulate the nervous system of birds. In addition, it can also simulate the high energy burst audio such as eagle, shotgun, firecracker, etc., which can effectively deter the approach of all kinds of birds and protect the contact network area of high-speed rail from bird interference.
Directional acoustic bird repellent device is highly targeted and can effectively cover the three-dimensional space protection area of high-speed rail contact network, ensuring that the sound pressure in the protection area of high-speed rail contact network is above 90dB, and birds will actively stay away from this area.
