Description
Technical Field
[0001] The utility model relates to the technical field of bird repellers, in particular to an airport shock wave bird repeller. Background Technique
[0002] The shock wave bird repeller is a comprehensive bird repelling device manufactured by integrating technologies such as subwoofer technology, electronic gun technology, impact gun technology, and cluster strong sound. Compared with the traditional single intimidating bird repelling method, the bird repelling effect is more obvious and lasting. It has a very significant bird repelling effect on large spiritual birds that are relatively difficult to drive away, such as egrets, pigeons, and Chinese bulbuls, and can adapt to a variety of use environments, such as power grids, airports, orchards, etc.
[0003] However, most of the currently used shock wave bird repellers are used in a fixed installation position. This is okay for narrow spaces, but for a vast environment such as an airport, the disadvantage of limited influence range is relatively obvious. Secondly, when facing a concentrated and frequently moving bird flock, the operation effect of the shock wave bird repeller in a fixed position will be greatly reduced. Content of the Utility Model
