Description

Technical Field

[0001] This utility model belongs to the technical field of bird deterrence devices, specifically relating to a bird deterrence device that uses continuous ultra-high frequency sound waves to interfere with the nerves of birds. Background Technology

[0002] High-altitude bird deterrent devices are often installed at high points in power systems or orchards. With rapid societal development, urban electricity consumption is increasing dramatically, leading to a proliferation of power transmission towers. These towers provide ideal habitats for birds to roost, defecate, and even nest. These bird behaviors can easily cause short circuits in power lines, resulting in power outages and severely impacting normal power transmission, causing significant economic losses. The same applies to orchards and other areas where bird activity poses a threat.

[0003] Existing bird deterrence devices rely on loud noises to scare away birds, which can lead to birds adapting over time, resulting in poor overall deterrence effectiveness. They also generate significant noise pollution for humans in the vicinity. Alternatively, fixed reflectors can be used, which have a limited range of bird deterrence and cannot meet the required range of bird deterrence. Furthermore, they are ineffective at night when there is no sunlight. Summary of the Invention

[0004] This invention provides a bird deterrent device that uses continuous ultra-high frequency sound waves to interfere with the nerves of birds. The purpose is to solve the problems of existing bird deterrent devices that use loud noise to drive away birds, which can lead to birds adapting in the long run, resulting in poor overall deterrent effect and causing a lot of noise to people in the surrounding area, or that use fixed reflectors with limited bird deterrent range, which cannot meet the requirements of bird deterrent range, and cannot deter birds at night when there is no sunlight.

[0005] This utility model provides a bird-repelling device that continuously interferes with the nerves of birds using ultra-high frequency sound waves. The device includes a base, a bracket fixed to the upper side of the base, a control box mounted on the bracket, a crossbar fixed to the top of the bracket, a rotating mechanism on the crossbar, a wind cup on the rotating mechanism, a reflective mechanism mounted on the lower side of the rotating mechanism and the crossbar, and an ultra-high frequency sound wave module in the control box.

[0006] Furthermore, the rotating mechanism includes a rotating box rotatably mounted on the lower side of the end of the crossbar. The rotating box has a universal bearing seat inside, and a rotating shaft is installed at the center of the universal bearing seat. The air cup is fixed to the periphery of the rotating box by a connecting rod.

[0007] By adopting the above technical solution, the wind cup is driven by wind to make the rotating box rotate horizontally around the end of the crossbar, while the universal bearing seat allows the rotating shaft to swing in the vertical plane. This dual motion mechanism ensures that the reflective ball tilts and wobbles while rotating, forming an irregular motion trajectory. The sealing structure of the rotating box can effectively prevent rainwater from entering the bearing and extend the service life of the equipment in the field.

[0008] Furthermore, the reflective mechanism includes a reflective ball eccentrically fixed to the bottom of the rotating shaft, an extension rod integrally formed on the bracket, and a reflector, a first annular light strip, and a second annular light strip fixed to the end of the extension rod. The reflector is located above the first annular light strip, the first annular light strip is located above the reflective ball, and the second annular light strip is located below the reflective ball.

[0009] By adopting the above technical solution, the downward arc surface design of the reflector reflects the upward scattered light of the first ring light strip to the space below, improving the light utilization rate. The first ring light strip illuminates the upper hemisphere of the reflector to form a dynamic high light spot, and the second ring light strip directly illuminates the lower hemisphere to form a dynamic high light spot and eliminate the bottom shadow. The two light strips work together to achieve 360° omnidirectional lighting for the sphere.

[0010] Furthermore, the reflector has a downward-curving surface.

[0011] By adopting the above technical solution, the curved surface can focus and scatter light, thereby increasing the density of reflected light flux, effectively expanding the illumination coverage radius of the area below, and preventing light from scattering upwards and causing light pollution.

[0012] Furthermore, the rotating shaft passes through the middle of the reflector and the first annular light strip, and the swing amplitude of the rotating shaft is less than the distance between the rotating shaft and the inner side of the reflector and the first annular light strip.

[0013] By adopting the above technical solution, the maximum swing angle limited by the universal bearing seat controls the offset of the rotating shaft, while the safety gap reserved in the inner diameter of the reflector and the light strip completely eliminates the interference risk of the reflector ball, the rotating shaft, the reflector and the first annular light strip.

[0014] Furthermore, the surface of the reflective sphere is alternately divided into a microprism reflection area and a mirror stainless steel plate area.

[0015] By adopting the above technical solution, the alternating microprism film and mirror panel produce two types of optical effects when the sphere rotates eccentrically. The bright spot generated in the mirror area stimulates the birds' escape instinct; the prism area decomposes white light into multi-colored diffuse spots, and a single rotation can produce multiple discrete spectral points. The alternating exposure frequency of the two types of areas changes randomly, making it impossible for birds to establish adaptive reflection.

[0016] Furthermore, the control box contains a battery, a photosensitive sensor, and a controller. A solar panel is located around the control box. The battery, photosensitive sensor, and controller are electrically connected. The solar panel is electrically connected to the battery. Both the first and second ring-shaped light strips are electrically connected to the battery and the controller.

[0017] By adopting the above technical solution, the photosensitive sensor detects the ambient illuminance in real time. When the sunlight intensity is lower than the limit, the double ring light strip is automatically activated. The controller uses random pulse modulation technology to make the light flash at irregular intervals of 0.5-3 seconds. The solar panel ensures that the power is stored under standard sunlight conditions to meet the needs of bird deterrence at night on continuous rainy days. The control box ensures that the electronic components operate stably in harsh outdoor environments.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the setting of the rotating mechanism, allows the wind bowl to be driven by the wind to rotate the rotating box horizontally around the end of the crossbar, while the universal bearing seat allows the rotating shaft to swing in the vertical plane. This dual motion mechanism ensures that the reflective ball tilts and sways while rotating, forming an irregular motion trajectory, which in turn can produce irregular sunlight reflection during the day, achieving a better bird-repelling effect.

[0020] 2. This utility model, through the setting of the reflective mechanism, uses the downward arc design of the reflector to reflect the upward scattered light of the first ring light strip to the space below, thereby improving the light utilization rate. The first ring light strip illuminates the upper hemisphere of the reflective sphere to form a dynamic high-brightness spot, and the second ring light strip directly illuminates the lower hemisphere to form a dynamic high-brightness spot and eliminate the bottom shadow. The two light strips work together to achieve 360° illumination of the sphere without dead angles. At the same time, different areas on the surface of the reflective sphere produce different optical effects, improving the bird-repelling effect and achieving the same bird-repelling effect at night.

[0021] 3. This utility model uses an ultra-high frequency sound wave module, which continuously releases ultra-high frequency sound waves that only birds can hear to drive away birds. When used in conjunction with a reflective ball, it greatly improves the bird-repelling effect.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a bird-repelling device that continuously interferes with the nervous system of birds using ultra-high frequency sound waves. It includes a base 1, a support 2 fixed to the upper side of the base 1, a control box 3 mounted on the support 2, a crossbar 4 fixed to the top of the support 2, a rotating mechanism 5 mounted on the crossbar 4, and a wind cup 6 mounted on the rotating mechanism 5. The rotating mechanism 5 includes a rotating box 51 rotatably mounted on the lower side of the end of the crossbar 4 via bearings. A universal bearing seat 52 is provided inside the rotating box 51, and a rotating shaft 53 is mounted at the center of the universal bearing seat 52. The wind cup 6 is fixed via a connecting rod. Around the rotating box 51, the wind cup 6 is driven by the wind to make the rotating box 51 rotate horizontally around the end of the crossbar 4, while the universal bearing seat 52 allows the rotating shaft 53 to swing in the vertical plane. This dual motion mechanism ensures that the reflective ball 71 tilts and wobbles while rotating, forming an irregular motion trajectory. The reflective ball 71 adopts a lightweight aluminum structure. The driving force generated by the wind cup 6 through the wind is sufficient to drive the reflective ball 71 to rotate and wobble. The sealing structure of the rotating box 51 can effectively prevent rainwater from entering the bearing and extend the service life of the equipment in the field.

[0031] Reference Figures 1-4 A reflector mechanism 7 is installed on the lower side of the rotating mechanism 5 and the crossbar 4. The reflector mechanism 7 includes a reflector ball 71 eccentrically fixed to the bottom of the rotating shaft 53. An extension rod 72 is integrally formed on the bracket 2. A reflector 73, a first annular light strip 74, and a second annular light strip 75 are fixed to the end of the extension rod 72. The reflector 73 is located above the first annular light strip 74, the first annular light strip 74 is located above the reflector ball 71, and the second annular light strip 75 is located below the reflector ball 71. The reflector 73 has a downward arc surface, which can focus and scatter light, thereby increasing the reflected light flux density and effectively expanding the lower area. To maximize the illumination coverage radius and prevent light pollution caused by upward scattering, the downward curved surface design of the reflector 73 reflects the upward scattered light from the first annular light strip 74 into the space below, where it is redirected back to the reflector sphere, improving light utilization. The first annular light strip 74 illuminates the upper hemisphere of the reflector sphere 71, forming a dynamic high-brightness spot. The second annular light strip 75 directly illuminates the lower hemisphere, also forming a dynamic high-brightness spot and eliminating bottom shadows. The two light strips work together to achieve 360° illumination of the sphere without blind spots. Both the first annular light strip 74 and the second annular light strip 75 use LED light strips, with red and green LED beads arranged alternately in a 1:1 ratio.

[0032] Reference Figures 1-4 The rotating shaft 53 passes through the middle of the reflector 73 and the first annular light strip 74. The swing amplitude of the rotating shaft 53 is less than the distance between the rotating shaft 53 and the inner side of the reflector 73 and the first annular light strip 74. The maximum swing angle limited by the universal bearing seat 52 controls the offset of the rotating shaft 53. The safety gap reserved in the inner diameter of the reflector 73 and the light strip completely eliminates the interference risk of the reflector ball 71, the rotating shaft 53, the reflector 73 and the first annular light strip 74.

[0033] Reference Figures 1-3 The surface of the reflective sphere 71 is alternately divided into a microprism reflective area and a mirror stainless steel plate area. The alternating microprism film and mirror plate produce two types of optical effects when the sphere rotates eccentrically. The bright spot generated in the mirror area stimulates the birds' escape instinct; the prism area decomposes white light into multi-color diffuse light spots. A single rotation can produce multiple discrete spectral points. The alternating exposure frequency of the two types of areas changes randomly, making it impossible for birds to establish adaptive reflection.

[0034] Reference Figures 1-4 The control box 3 contains a battery, a photosensitive sensor, and a controller. It also includes an ultra-high frequency (UHF) acoustic module electrically connected to the battery. This module comprises a CMUTC2020 piezoelectric ceramic transducer, a BPF18K55 LC bandpass filter, an AD9833 DDS signal generator, and a waveguide horn. A solar panel 31 is located around the control box 3. The battery, photosensitive sensor, and controller are electrically connected. The first and second ring-shaped light strips 74 and 75 are also electrically connected to the battery and controller. The photosensitive sensor detects ambient illuminance in real time and automatically activates the double ring-shaped light strips when the sunlight intensity is below a certain limit. The controller uses random pulse modulation technology to make the lights flash irregularly at intervals of 0.5-3 seconds. The solar panel 31 ensures energy storage under standard sunlight conditions to meet the bird-repelling needs during continuous cloudy or rainy nights. The control box 3 ensures stable operation of its electronic components in harsh outdoor environments. Simultaneously, the controller controls the UHF acoustic module. The block continuously emits sound waves that only birds can hear, driving away birds in the area. Combined with the reflective ball 71, this enhances the overall bird-repelling effect. The controller uses an STM32F103C8T6 industrial-grade microcontroller, and the photosensitive sensor is a GL5528 photoresistor module. The positive and negative terminals of the solar panel 31 are connected to the charging input of the battery via an MPPT charging controller. The battery output is connected in parallel to the controller's power management module and the power supply pin of the photosensitive sensor. The signal output of the photosensitive sensor is connected to the PA1 analog input pin of the controller. The controller's two PWM output channels, PB0 and PB1, are connected to the first ring light strip 74 and the second ring light strip 75 via an IRF3205 MOSFET driver circuit, respectively, and to the PT4115 driver chip. PB0 controls the first ring light strip 74, and PB1 controls the second ring light strip 75. The controller's built-in program triggers random pulse modulation of the dual light strips based on the photosensitive sensor signal, resulting in intermittent flashing of the red and green lights. This is existing technology and will not be elaborated further.

[0035] The specific implementation method is as follows: During the day, the wind cup 6 is driven by the wind to rotate the rotating box 51 horizontally. At the same time, the universal bearing seat 52 allows the rotating shaft 53 to swing slightly, causing the eccentrically fixed reflective ball 71 to perform irregular three-dimensional motion. The microprism reflection area and the mirror stainless steel plate area alternately distributed on the surface of the ball continuously reflect sunlight during rotation. The mirror area generates a high-speed moving bright spot that directly stimulates the bird's visual nerves, while the prism area scatters a changing colored diffuse spot. The two types of optical effects switch randomly, forming an unpredictable visual attack. At night or in low light conditions, when the photosensitive sensor detects that the ambient illuminance is below a threshold, it sends a signal to the controller. The controller then outputs a random pulse modulation signal, causing the red and green LEDs of the first and second ring light strips 74 and 75 to flash alternately. The light from the first ring light strip 74 illuminates the upper half of the sphere, producing dynamic reflection, while the light from the second ring light strip 75 shines directly on the lower half of the sphere, producing dynamic reflection and eliminating shadows. At the same time, the reflector 73 reflects the upward-scattered light downwards. The two light strips work together to form an irregular flashing light net covering 360° of the sphere. Meanwhile, the ultra-high frequency sound wave module can continuously emit ultra-high frequency sound waves under the action of the controller, cooperating with the reflector sphere 71 to greatly improve the overall bird-repelling effect. The entire system is powered by the solar panel 31 charging the battery, which in turn powers the entire system, achieving all-weather self-sustaining operation. Ultimately, the system achieves a continuous bird-repelling effect through dynamic light and shadow interference.
