Abstract
Description
Technical Field
[0001] This invention belongs to the field of bird deterrence technology, specifically relating to a multi-bladed rotary bird deterrence device based on acoustic resonance. Background Technology
[0002] The multi-blade rotating bird deterrent device based on acoustic resonance is a composite bird deterrent device that combines acoustic interference and physical deterrence. It amplifies the bird deterrent signal through the reflective characteristics of the multi-blade rotating structure and the acoustic resonance effect, creating dual interference to the birds' hearing and living environment, ultimately forcing the birds away from the target area.
[0003] Bird deterrent devices using sound interference and leaf reflection have certain limitations in practical applications. Although sound interference can stimulate the bird's auditory system with sound waves of a specific frequency, forcing it to flee, after prolonged use, birds will gradually adapt to the fixed frequency pattern of sound wave signals, and the deterrent effect will decrease significantly over time. Meanwhile, leaf reflection relies on natural light or auxiliary light sources and interferes with the bird's vision through the flashing of reflective strips or mirror-like leaves. However, the reflective effect is greatly weakened in the dark or in environments with insufficient light, making it difficult to form an effective deterrent.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 10 As shown, the present invention provides a technical solution: a multi-blade rotary bird deterrent device based on acoustic resonance, comprising a main control box 1, a generator 2 fixedly installed inside the main control box 1, a main rotating shaft 3 fixedly connected to the output shaft of the generator 2, a sound-emitting chamber 4 fixedly connected above the main control box 1, loudspeakers 5 arranged on both sides of the sound-emitting chamber 4, the main rotating shaft 3 penetrating through the inner wall of the sound-emitting chamber 4, a reflective blade structure 6 fixedly connected to the top of the main rotating shaft 3, a rotating tray 7 fixedly connected above the reflective blade structure 6, multiple concave mirrors 8 arranged on the surface of the rotating tray 7, a simulated eagle eye 9 fixedly connected to the top of the rotating tray 7, a gong-beating assembly arranged above the main control box 1, the gong-beating assembly comprising multiple gongs 16, the surface materials of the multiple gongs 16 being different, the gong-beating assembly producing sound by striking the surface of the gongs 16, an alternation component arranged between the multiple gongs 16, the alternation component being used to drive the positions of the multiple gongs 16 to exchange with each other, and a power supply component providing power to the generator 2 arranged on one side of the generator 2.
[0023] In operation: This device is suitable for use in open outdoor areas for bird deterrence. During use, the power supply unit converts solar energy into electrical energy for generator 2, which drives the main shaft 3 to rotate. The rotation of the main shaft 3 synchronously drives the reflective blade structure 6 and the rotating tray 7 to rotate as well. The reflective blade structure 6 achieves 360-degree sunlight reflection without blind spots through a mirror coating. Combined with the concave mirrors 8 on the rotating tray 7, which are arranged at a 45-degree angle, a dynamic high-intensity light scanning zone is formed. This utilizes birds' instinctive avoidance reaction to sudden strong light to achieve visual deterrence. The simulated eagle eye 9 on the top, combined with the rotational movement, generates dynamic predator visual signals, enhancing the deterrent effect against predators. The sound chamber 4 contains a built-in intelligent sound wave generator, which plays a mixed audio of frequency-modulated ultrasonic waves and raptor calls through a loudspeaker 5, interfering with the birds' auditory positioning system. Because light intensity decreases at night, the reflective effect is significantly weakened, and birds gradually adapt to fixed-frequency sound signals, the deterrent effect decreases significantly over time. In this specific embodiment, multiple gongs 16 made of different materials are used, each producing a different sound when struck. These gongs 16 can be made of copper, aluminum, stainless steel, etc. During the day, when there is sunlight, the power supply component can continuously charge the battery 36, storing sufficient electrical energy. At night, even without solar energy input, the electrical energy stored in the battery 36 can continue to power the generator 2, enabling the generator 2 to operate at night. The power supply at night ensures that generator 2 can run continuously. The rotational force of generator 2 will drive the gong-beating assembly to intermittently strike one of the gongs 16 to produce a sound. The piercing sound waves emitted by gong 16 will deter birds and prevent them from approaching the area. After a period of time, the alternation assembly will exchange the positions of multiple gongs 16, so that when the gong-beating assembly is in continuous motion, it can strike gongs 16 of different materials at intervals, thereby producing different piercing sounds to drive away birds. This ensures that the sound signal characteristics are updated every period of time, effectively preventing birds from developing auditory adaptation. It should be noted that this device will generate some noise when used at night, so it needs to be installed in an uninhabited area or far away from residential areas. Through the above embodiments, the gong-striking assembly, driven by the generator 2, intermittently strikes gongs 16 made of different materials, generating high-frequency, piercing sound waves to create an auditory deterrent to birds. This compensates for the reduced effectiveness of the reflective blade structure 6 at night, achieving continuous bird deterrence through sound waves day and night. By using an alternating assembly, the positions of multiple gongs 16 are rotated periodically, ensuring that the gong-striking assembly can continuously strike gongs 16 made of different materials at regular intervals. This prevents birds from adapting to fixed sound signals, achieves periodic updates of sound frequency characteristics, and thus improves the bird deterrence effect.
[0024] like Figures 7 to 9As shown, the gong-beating assembly includes a turntable 14, a main rotating rod 18 is provided at the eccentric part of the turntable 14, an elastic arc plate 19 is fixedly connected to one side of the main rotating rod 18, an impact block 20 is fixedly connected to one side of the elastic arc plate 19, and a transmission assembly that drives the turntable 14 to rotate is provided on one side of the turntable 14.
[0025] During operation: In the initial state, one end of the main rotating rod 18 is fixed to the eccentric part of the turntable 14. When the transmission component drives the turntable 14 to rotate, the main rotating rod 18 will rotate around the center of the turntable 14, forming an eccentric circular motion trajectory with a specific radius. During this process, the elastic arc plate 19, which is fixedly connected to the main rotating rod 18, performs eccentric circular motion synchronously. As the elastic arc plate 19 continues to rotate, when it completes a complete circular motion cycle and contacts the surface of one of the gongs 16, the impact block 20 on one side of the elastic arc plate 19 will apply a vertical impact force to the surface of the gong 16 in an instant, causing the gong 16 to vibrate and make a sound, thereby achieving efficient acoustic bird deterrence.
[0026] like Figures 7 to 9 As shown, a connecting frame 29 is fixedly connected to the top of the main control box 1, a bearing component 30 is fixedly connected to the top of the connecting frame 29, a central rotating shaft 17 is rotatably connected to the inner wall of the bearing component 30, multiple gongs 16 are evenly distributed and connected to the outer wall of the central rotating shaft 17, an elastic sand bar 21 is fixedly connected between the two ends of the elastic arc plate 19, and a rotation limiting component is provided on one side of the central rotating shaft 17 to restrict the central rotating shaft 17 to rotate only in one direction.
[0027] During operation: This solution has four gongs 16, which are fixed at equal angular intervals on the outer wall of the central rotating shaft 17. When the impact block 20 rotates with the elastic arc plate 19 to contact the gong 16, the rotation limiting component locks the central rotating shaft 17 in the opposite direction of rotation. Therefore, when the gong 16 is impacted, it can only absorb energy through its own deformation and will not reverse the rotation of the central rotating shaft 17, thus ensuring that the impact force is completely converted into sound wave energy. At the moment of impact, the elastic arc plate 19 undergoes elastic deformation due to the reaction force of the gong 16, increasing its arc degree. Simultaneously, the turntable... The continuous rotational force of 14 causes the free end of the elastic arc plate 19 to actively contract inward, reducing the overall rotation diameter of the elastic arc plate 19, thus allowing it to smoothly pass over the surface of the gong 16. When the elastic arc plate 19 deforms, it will squeeze the elastic sand rod 21. After the impact block 20 passes, the elastic sand rod 21 recovers its deformation. Since the elastic sand rod 21 is designed to be threaded and contains sand, it will also produce the sound of sand hitting when it recovers its deformation, further improving the acoustic bird-repelling function. After completing the impact on the gong 16, the elastic arc plate 19 unfolds again, ready for the next impact.
[0028] like Figure 7 and Figure 9As shown, the alternating assembly includes a gear 27, which is fixedly connected to the outer wall of one end of the central rotating shaft 17. A driven rod 25 is fixedly connected to one side of the main rotating rod 18, and an arc-shaped toothed plate 26 is fixedly connected to one side of the driven rod 25. The teeth of the arc-shaped toothed plate 26 can mesh with the teeth of the gear 27. A timing assembly is provided on the surface of the turntable 14, which can drive one end of the main rotating rod 18 to move to the center of the turntable 14.
[0029] During operation: The main rotating rod 18 is fixed at the eccentric position of the turntable 14. As the turntable 14 rotates, the arc-shaped toothed plate 26 and the gear 27 fixed on the central rotating shaft 17 are in a disengaged state, with no meshing contact. At this time, the elastic arc-shaped plate 19 drives the impact block 20 to continuously strike the gong 16, forming a regular sound wave output. When the turntable 14 rotates continuously for a preset time (controlled by the timing component), the timing component translates the fixed point of the main rotating rod 18 from the eccentric position towards the center of the turntable 14, reducing the rotation radius of the main rotating rod 18. The elastic arc-shaped plate 19 and the impact block 20 then move within their respective trajectories. The main rotating rod 18 moves inward to the area where it meshes with the gear 27, avoiding the impact range of the gong 16. The arc-shaped toothed plate 26 moves inward with the main rotating rod 18 to the area where it meshes with the gear 27. Its teeth mesh with the gear 27, driving the central rotating shaft 17 to rotate 90 degrees in one direction. The central rotating shaft 17 drives the four gongs 16 to rotate synchronously, realizing the position exchange of adjacent gongs 16. After the position exchange is completed, the main rotating rod 18 returns to the eccentric position of the turntable 14. The arc-shaped toothed plate 26 disengages from the position where it can mesh with the gear 27. The elastic arc plate 19 restores its original rotation radius. The impact block 20 continues to periodically impact the replaced gong 16.
[0030] like Figure 7 and Figure 9 As shown, the number of teeth on the arc-shaped toothed plate 26 is one-quarter of the number of teeth on the gear 27.
[0031] During operation: Since the gongs 16 are fixed at equal angular intervals on the outer wall of the central rotating shaft 17, when the arc-shaped toothed plate 26 and the gear 27 engage once, the central rotating shaft 17 will rotate 90 degrees in the direction that can be rotated, thereby realizing the accurate position exchange between the four gongs 16.
[0032] like Figures 6 to 7 As shown, the timing component includes a timing controller 28, which is fixedly connected to the top of the connecting frame 29. The surface of the turntable 14 is provided with a sliding groove 22, and an electrically controlled telescopic rod 23 is fixedly connected inside the sliding groove 22. One end of the electrically controlled telescopic rod 23 is fixedly connected to an inner slider 24, which is slidably connected to the inner wall of the sliding groove 22. One side of the inner slider 24 is fixedly connected to one end of the main rotating rod 18.
[0033] During operation: The timer controller 28 is in standby mode, the electric telescopic rod 23 maintains its default length, and the inner slider 24 is in an eccentric position away from the center of the turntable 14 within the slide groove 22. When the timer controller 28 detects that the preset time has arrived, it activates the electric telescopic rod 23, which retracts and pulls the inner slider 24 to slide along the slide groove 22 toward the center of the turntable 14. The main rotating rod 18 moves inward synchronously with the inner slider 24, reducing its rotation radius. The trajectory of the elastic arc plate 19 and the impact block 20 retracts, avoiding the impact range of the gong 16. The arc toothed plate 26 moves to the meshing area with the gear 27, driving the central rotating shaft 17 to rotate 90 degrees, thereby realizing the position exchange of the gong 16.
[0034] like Figure 7 and Figure 10 As shown, the rotation limiting assembly includes a ratchet 31, which is fixedly connected to the outer wall of the central rotating shaft 17 away from the gear 27. A trapezoidal block 32 is engaged between the teeth of the ratchet 31. An inner insert rod 33 is fixedly connected to the bottom of the trapezoidal block 32. The inner insert rod 33 is inserted into the inner wall of the connecting frame 29. A spring 34 is fixedly connected between the trapezoidal block 32 and the connecting frame 29.
[0035] During operation: When the arc-shaped toothed plate 26 meshes with the gear 27, causing the central rotating shaft 17 to rotate in the forward direction, the teeth of the ratchet 31 push the inclined surface of the trapezoidal block 32, causing it to compress the spring 34 and retract into the connecting frame 29. The inner insert rod 33 slides within the connecting frame 29, allowing the ratchet 31 to pass smoothly, and the central rotating shaft 17 rotates normally. When the impact block 20 impacts the central rotating shaft 17, causing it to attempt to rotate in the reverse direction, the trapezoidal block 32, under the elastic force of the spring 34, has its right-angled surface inserted between the teeth of the ratchet 31. The insertion structure of the inner insert rod 33 and the connecting frame 29 further restricts the displacement of the trapezoidal block 32, thereby locking the ratchet 31 and preventing the central rotating shaft 17 from rotating in the reverse direction.
[0036] like Figure 6 As shown, the transmission assembly includes a drive wheel 10, which is fixedly connected to the outer wall of the main rotating shaft 3. The teeth of the drive wheel 10 mesh with a driven wheel 11. A rotating rod 12 is fixedly connected to the inner wall of the driven wheel 11. The rotating rod 12 is rotatably connected to the inner wall of the main control box 1. A bevel gear 13 is fixedly connected to one side of the turntable 14 and the top of the rotating rod 12. The teeth of the two bevel gears 13 mesh with each other. A bearing component 15 is fixedly connected to the top of the main control box 1. The inner wall of the bearing component 15 is rotatably connected to the shaft of one of the bevel gears 13.
[0037] During operation: When the generator 2 drives the main shaft 3 to rotate, it will drive the driven wheel 11 to rotate through the driving wheel 10. The driven wheel 11 drives the turntable 14 to rotate through the transmission relationship between the rotating rod 12 and the bevel gear 13.
[0038] like Figures 2 to 3As shown, the power supply components include a photovoltaic panel 35, a storage battery 36 is installed inside the main control box 1, and a power converter 37 is installed on one side of the storage battery 36.
[0039] During operation: Solar energy is absorbed by the photovoltaic panel 35 and transmitted to the battery 36 for storage. When the generator 2 needs to be started, the battery 36 converts the solar energy into electrical energy through the power converter 37 and transmits it to the generator 2, thereby realizing the continuous operation of the generator 2.
[0040] like Figures 2 to 3 As shown, a hinge seat 39 is fixedly connected above the battery 36, and a support block 40 is hinged to the inner wall of the hinge seat 39. One end of the support block 40 is fixedly connected to the bottom of the photovoltaic panel 35. An arc-shaped telescopic rod 41 is fixedly connected between one side of the hinge seat 39 and one side of the support block 40. A four-quadrant sensor 38 is fixedly installed on the top of the main control box 1.
[0041] During operation: Through the coordinated action of the four-quadrant sensor 38 and the mechanical structure, the photovoltaic panel 35 achieves automatic light tracking function. The four-quadrant sensor 38 can detect the offset of the solar spot on the sensor surface in real time and control the arc-shaped telescopic rod 41 to extend and retract. As the telescopic rod extends and retracts, the support block 40 rotates around the hinge seat 39, which drives the photovoltaic panel 35 to adjust its orientation angle synchronously, so that the photovoltaic panel 35 can receive the maximum amount of solar energy.
