[0004] In use, the ultrasonic sound generator emits varying ultrasonic waves to stimulate the nervous system of birds, making them stay away from the coverage area, the rechargeable sound emits a sound that scares birds away, and the color lamp emits red and green light that birds are most afraid of, making them stay away.

[0005] For the above-mentioned related technology, the use of ultrasonic waves, sound and color light to drive birds produces effects through sound and strong light, but when driving birds through sound and strong light in a large area, the sound and strong light will be more dispersed, resulting in reduced bird repelling effect. UTILITY MODEL CONTENTS

[0006] In order to improve the driving effect of birds in a large area, the utility model provides a photovoltaic power generation bird repeller.

[0007] The utility model provides photovoltaic power generation bird repeller, adopts the following technical scheme:

[0008] The photovoltaic power generation bird repeller comprises a support, a sound wave emitter and a repelling device, the sound wave emitter and the repelling device are fixedly installed on the support, the sound wave emitter is used for emitting variable frequency sound waves, the repelling device comprises a controller, a radar, a rotating assembly, a repelling assembly and a converging assembly, a fixed end of the rotating assembly is fixedly installed on the support, the repelling assembly and the converging assembly are fixedly installed on the rotating assembly; the converging assembly comprises a converging cover, the converging cover covers the repelling assembly, and an opening is arranged on the converging cover; the radar is fixedly installed on the support, and the radar, the rotating assembly and the repelling assembly are electrically connected with the controller.

[0009] By adopting the above technical scheme, the photovoltaic bird repeller is fixedly installed on the photovoltaic array area by using the support, and the sound wave emitter is turned on to emit interference sound waves, so as to reduce the probability of birds staying in the photovoltaic array area. Meanwhile, the radar performs real-time scanning, and when the radar detects that birds stay in the photovoltaic array area, the controller controls the rotating assembly to rotate, the repelling assembly installed on the rotating assembly emits repelling information to repel the birds. When the repelling assembly emits the repelling information, the converging assembly converges the signal of the repelling information emitted by the repelling assembly in the converging cover, such as converging light or sound information in the converging cover, and releasing in the opening direction of the converging cover. Meanwhile, the releasing direction is aligned with the area where the birds stay by cooperating with the rotating assembly, so that the directional release and propagation of the repelling signal can be realized. In this way, the repelling signal is converged by the converging assembly and released in a specific direction, so that the repelling information released in the releasing direction can be greatly enhanced, and the releasing direction of the repelling information can be controlled by the converging assembly cooperating with the rotating assembly, so that the repelling effect on the birds in the specific direction can be improved.

[0010] Optionally, the converging assembly further comprises an emission cover, the cross section of the emission cover is trapezoidal, one end of the emission cover with a small opening is connected to the opening of the converging cover, and the other end of the emission cover with a large opening is arranged in a direction away from the repelling assembly.

[0011] After the repelling information such as sound, ultrasonic wave and light is converged in the converging cover, the divergence in each direction can be reduced. When the information is released at the opening of the converging cover, the information lacks direction and diverges in each direction. By adopting the above technical scheme, the emission cover can guide the signal released at the opening of the converging cover, and the signal released at the opening of the converging cover is emitted towards the direction of the emission cover. The trapezoidal cross section of the emission cover can control most of the released signal to be transmitted in the fan-shaped area formed by the trapezoid, so that the directional emission and propagation of the repelling information can be realized. In this way, the emission cover can guide the repelling information converged in the converging cover, so that the repelling information can be controlled to propagate in a specific direction, and the repelling effect on the birds in the specific direction can be further improved.

[0012] Optionally, the expelling component is a sound generator, the sound generator is installed inside the converging cover, the inner end faces of the converging cover and the emitting cover are both provided in a smooth manner, and the inner wall of the emitting cover is provided in a parabolic manner.

[0013] By adopting the above technical solution, the sound emitter emits the call of the bird's natural enemy, the scream of the same kind, or the ultrasonic information that makes the bird feel uncomfortable. The sound signal emitted by the sound emitter is continuously emitted inside the converging cover and finally released from the opening of the converging cover. The inner end faces of the converging cover and the emitting cover are provided in a smooth structure, which can reduce the number of reflections of sound waves inside the emitting cover and the converging cover, thereby reducing the absorption of sound waves by the side walls of the converging cover and the emitting cover. The inner wall of the emitting cover is provided in a parabolic structure, which can effectively transmit and focus sound between the two parabolic surfaces. Different parabolic radii can also control the range of sound propagation area, thereby improving the expelling effect on birds and covering a larger range.

[0014] Optionally, and / or the expelling component is a light generator, the light generator is installed inside the converging cover, and the inner end faces of the converging cover and the emitting cover are both provided with a reflective material.

The light is continuously reflected on the reflective material inside the converging cover and finally enters the emitting cover from the opening of the converging cover. The emitting cover collects the light and emits it away from the light generator. The reflective material inside the converging cover and the emitting cover can reflect the light and reflect it to the specified direction by controlling the structure of the reflecting cover. In this way, birds can be expelled by light and sound, thereby improving the expelling effect on birds.

[0016] Optionally, the light generator is further provided with a light-sensitive switch, the light-sensitive switch is installed outside the converging cover, and the light-sensitive switch is electrically connected with the light generator.

[0017] Since the environment is relatively bright during the day, the effect of expelling birds by light is not good. By adopting the above technical solution, the light generator is controlled by the light-sensitive switch. When the light intensity detected by the light-sensitive switch is less than a set threshold, the light generator is turned on, so that the expelling component expels birds by sound during the day and expels birds by light and sound in a dark environment. In this way, the light generator can be turned off when the light effect is not good, thereby saving the consumption of the light generator and prolonging the service life of the light generator.
