[0002] With the continuous development and improvement of the power system, the harm of birds to the power system has long been a difficulty and pain point. The harm of birds to the power system includes the excrement of birds on the transmission line towers. Due to its viscosity and conductivity, it may form a conductive path along the surface of the insulator, causing line flashover accidents, resulting in tripping and power outages. The body of the bird or its activities may cause the air gap of the transmission line to be short-circuited, causing discharge phenomena, causing line tripping, etc., seriously affecting the safety of the power system and the life safety of birds. At present, there are mainly mechanical bird repellers that reflect sunlight, sound and light bird repellers, ultrasonic bird repellers, etc. on the market. For example, the Chinese patent with the authorization announcement number CN220023981U discloses a double-mirror rotating and retractable bird repeller that repels birds only through a reflector. The above-mentioned bird repellers all have the problem that birds will adapt after long-term use, and the bird repeller effect will be greatly reduced or almost ineffective, especially for large birds of prey such as kestrel and black-winged kite.

[0003] With the development of sound wave technology, ultrasonic and directional sound wave technologies have been derived.
