Description

Technical Field

[0001] This invention relates to the field of orchard pest control technology, and in particular to an orchard bird deterrent device. Background Technology

[0002] The "adaptability" of birds during bird control essentially refers to the common phenomenon where birds develop a habituation response to persistent and harmless deterrent stimuli, leading to the gradual ineffectiveness of bird control measures. This phenomenon is one of the most challenging bottlenecks in current orchard bird control. Specifically, acoustic bird deterrent methods (such as firecracker sounds, ultrasound, and predator calls) are effective initially, but after a period of continuous playback, birds quickly recognize that these sounds do not carry real danger and resume their feeding behavior. Visual stimuli (such as scarecrows, reflective strips, and lasers) also face limitations; fixed or regularly moving objects are easily adapted to by birds, and once they find these "imaginary enemies" to be harmless, they will re-enter the orchard.

[0003] Existing bird deterrence solutions are mostly based on adjusting parameters after birds have developed adaptive behaviors (such as switching sound frequencies or changing the flashing rhythm of lights). However, these countermeasures are still limited to the passive switching of stimulus parameters and the simple superposition of multimodal signals. They belong to a "stimulus-feedback-correction" lag mode and are difficult to form a sustained deterrence effect. Summary of the Invention

[0004] The purpose of this invention is to provide an orchard bird deterrent device that has a continuous deterrent effect and effectively delays the visual and auditory adaptation of birds to deterrent signals.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an orchard bird deterrent device, comprising a housing and an electric drive mechanism disposed within the housing, wherein a bowl-shaped rotating body with its rim facing upward is rotatably connected to the top of the housing, and the bowl-shaped rotating body is continuously rotated by the electric drive mechanism, and further comprising: The sound and light driving component includes multiple sound and light generators, each of which is disposed at a different position on the inner wall of the bowl-shaped rotating body, and each of the sound and light generators has a different timbre and a different flashing light color. The reflective assembly includes a support rod that is vertically fixed to the center of the bottom wall of the box, the top of the support rod that passes vertically upward through the center of the bowl-shaped rotating body, and a reflective ball that is rotatably connected to the top of the support rod. The swing trigger assembly includes multiple elastic connecting rods and impact balls. One end of each elastic connecting rod is hinged to the bottom of the reflective ball in a vertical plane. Each impact ball is fixedly connected to the other end of the corresponding elastic connecting rod. The rotation center of the bowl-shaped rotator coincides with the center of the reflective ball. The reflective ball drives the impact ball to strike the trigger end of the sound and light generator through the elastic connecting rods.

[0006] By adopting the above technical solution, when the electric drive mechanism drives the bowl-shaped rotating body to rotate, the friction between the bowl-shaped rotating body and the impact ball can also drive the elastic connecting rod and the impact ball to rotate, which in turn drives the reflective ball to rotate. On the one hand, the natural light is diffused to the surrounding orchard by the reflection of the spherical surface, forming a dynamic flashing strong light interference, which visually disrupts the birds' sense of security in their habitat. On the other hand, the centrifugal force generated by the rotation causes the impact ball at the end of the elastic connecting rod to swing randomly, making the timing and combination of the sound and light generators with different timbres and different flashing lights completely irregular. Birds cannot form fixed adaptive memories, effectively preventing birds from developing habitual adaptations to fixed sound or visual patterns.

[0007] A further feature of the present invention is that a plurality of through holes are spaced apart along the circumferential direction on the side wall of the bowl-shaped rotating body, and each of the sound and light generators is respectively embedded and fixed in the corresponding through hole, and the trigger end of the sound and light generator is located on the inner side wall surface of the bowl-shaped rotating body.

[0008] By adopting the above technical solution, the through holes on the sidewall of the bowl-shaped rotator are evenly distributed circumferentially, exposing the trigger ends of each acousto-optic generator to the inner sidewall surface of the bowl-shaped rotator. When the impact ball is thrown outward under centrifugal force, the arc-shaped inner wall provides a smooth and continuous sliding guide surface for the impact ball, allowing it to roll or slide smoothly along the inner wall, reducing jamming or energy loss caused by structural corners. At the same time, the geometry of the bowl-shaped rotator ensures that the tangential angle between the trigger end at each through hole and the swing trajectory of the impact ball remains consistent, ensuring that the impact ball can touch the trigger end with similar force and angle regardless of the rotation angle of the bowl-shaped rotator, improving the reliability and consistency of triggering, and thus ensuring the stable realization of the randomness of the acousto-optic combination.

[0009] A further feature of the present invention is that it also includes a wind-driven mechanism, wherein the reflective ball is driven to rotate continuously by the wind-driven mechanism, the direction of rotation of the reflective ball is opposite to the direction of rotation of the bowl-shaped rotating body, and the wind-driven mechanism includes a support shaft vertically fixedly connected to the center position of the top of the reflective ball, and fan blades are uniformly fixedly connected to the outer surface of the support shaft.

[0010] By adopting the above technical solution, the wind vane is directly fixed to the support shaft at the center of the top of the reflective sphere, making the wind vane and the reflective sphere a single rotating component. When natural wind acts on the wind vane, the wind vane drives the reflective sphere to rotate synchronously around the support rod. No additional transmission mechanism is needed, reducing energy transmission loss and improving wind power utilization efficiency. At the same time, the reflective sphere, as the center of rotation, has its bottom hinged elastic connecting rod, and the amplitude of its outward swing under centrifugal force is directly related to the rotational speed of the reflective sphere. The wind vane rotational speed changes in real time with the wind force, causing the swing amplitude and impact frequency of the impacting sphere to change dynamically. This results in a non-linear coupling between the sound and light triggering sequence and the natural wind speed, further enhancing the unpredictability of the scare signal and effectively preventing birds from adapting to the scare signal by memorizing specific rotational speed patterns.

[0011] A further configuration of the present invention is as follows: the electric drive mechanism includes a circular housing and an electric fan fixedly connected to the bottom wall of the housing, and a transmission solenoid fixedly connected to the bottom of the bowl-shaped rotating body in the vertical direction. The support rod passes through the transmission solenoid and is fixedly connected to the housing. The bottom of the transmission solenoid is rotatably connected to the circular housing. The air inlet end of the circular housing is sealed to the air outlet end of the electric fan for sending airflow into the circular housing to drive the transmission solenoid to rotate, thereby driving the bowl-shaped rotating body to rotate.

[0012] By adopting the above technical solution, a third battery is fixedly connected to the inner bottom wall of the enclosure. The electric fan is electrically connected to the third battery, which powers the fan. In windy weather, the external wind can drive the bowl-shaped rotating body to rotate; in windless or still weather conditions, the electric fan can actively drive the bowl-shaped rotating body to rotate, causing the impact ball to continue swinging under friction and centrifugal force, thereby triggering the normal operation of the sound and light deterrent component. With the above configuration, the sound and light deterrent component can still operate in windless conditions, ensuring that the deterrent device can continuously generate stimulus signals with random combinations of multiple colors and sounds under various weather conditions, thereby maintaining the continuous breaking effect on bird adaptation and avoiding the opportunity for birds to adapt due to interruption of deterrence caused by weather.

[0013] A further configuration of the present invention is as follows: the sound and light generator includes a housing fixedly installed on the inner wall of a bowl-shaped rotating body; the switch triggering part is slidably connected along the inner side wall of the housing; an intermediate plate is fixedly disposed inside the housing; a piezoelectric switch is installed on the side of the intermediate plate near the switch triggering part; a voice playback module is installed on the side of the intermediate plate away from the switch triggering part; the piezoelectric switch is electrically connected to the voice playback module; and the piezoelectric switch is located on the sliding path of the switch triggering part; a plurality of sound-permeable holes are provided on the side wall of the housing near the voice playback module. Multiple colored spotlights of different colors are also fixedly installed on the intermediate plate, and the irradiation direction of each colored spotlight is towards the reflector ball.

[0014] By adopting the above technical solution, a first storage battery is installed inside the bowl-shaped rotating body. The piezoelectric switch, voice playback module, and colored spotlights are all electrically connected to the first storage battery. When the impact ball strikes the switch trigger, the trigger slides along the inner wall of the housing, touching the piezoelectric switch located on its sliding path. After the piezoelectric switch is turned on, the voice playback module is simultaneously activated to play a preset bird-repelling sound (the sound is transmitted from the sound hole), and the colored spotlights emit colored light. After the colored light shines on the surface of the reflective ball, it is reflected by the reflective ball and diffuses in all directions, transforming the point light source into a surface light source and expanding the visual warning range. The first storage battery provides power to the entire assembly. Each sound and light generator is independently powered and controlled, and multiple components do not interfere with each other, providing a reliable structural basis for realizing "random combinations of multiple colors and multiple sounds".

[0015] A further feature of the present invention is that the switch trigger part is shaped like an arc-shaped pressing plate, and the arc-shaped surface of the arc-shaped pressing plate is on the same arc surface as the inner wall surface of the bowl-shaped rotating body. When

[0016] By adopting the above technical solution, when the impact ball swings to this position with centrifugal force, it directly presses the arc-shaped pressing plate. After being subjected to force, the pressing plate slides inward along the inner wall of the shell, touching the piezoelectric switch to complete the triggering. After the external force disappears, the arc-shaped pressing plate relies on the elasticity of the piezoelectric switch to reset, preparing for the next triggering. This ensures that multiple sound and light generators can still be reliably triggered when the speed of the wind turbine blades changes, maintaining the randomness and diversity of the sound and light combination, thereby continuously cracking the bird's adaptability.

[0017] A further feature of the present invention is that the duration of each sound played by the voice playback module is set to 5s-20s.

[0018] By adopting the above technical solution, when the impact ball triggers the piezoelectric switch, the voice playback module starts and continuously plays the preset bird-repelling sound for a duration of 10 to 20 seconds (which can be set by the internal timing circuit). After the playback is completed, it automatically stops and waits for the next trigger. Because the impact time is different for multiple voice playback modules, the start and end times of their playback are interleaved, forming a wave-like "sound wave" effect. The set playback duration causes the working states of each voice playback module to have a complex timing sequence of "overlapping" and "interleaving", which further increases the unpredictability of the sound combination and strengthens the effect of preventing birds from becoming accustomed to it.

[0019] A further embodiment of the present invention includes a laser irradiation assembly comprising a support plate horizontally fixedly connected to the top of the support rod, a light control switch mounted on the support plate, a second battery detachably connected to the bottom of the support plate, an arc-shaped rod fixedly connected to the upper surface of the support plate, and a plurality of green lasers with outward-facing lamp heads fixedly mounted on the arc-shaped rod; the second battery, the light control switch, and each of the green lasers are electrically connected, and the light control switch is used to control the on / off supply of power from the second battery to the green lasers.

[0020] By employing the aforementioned technical solution, multiple green lasers are mounted on an arc-shaped pole, with the lamp heads facing outwards. When operational, they emit green laser beams that form a prominent light column in the atmosphere. These beams are automatically activated by a light-controlled switch at dusk, night, or on cloudy days. The green laser column provides a strong visual deterrent to birds flying at long distances, thus compensating for the limited range of the sound and light deterrent components, which are unable to cover distant airspace. As a supplementary means of dynamic visual signaling, the laser's illumination direction and angle can be flexibly adjusted according to the installation position of the arc-shaped pole to cover different spatial areas. Simultaneously, the random reflected light generated by the reflector sphere and the colored light emitted by the colored spotlights jointly participate in the visual interference system. The laser provides a static, directional light column, the reflector sphere provides dynamic, scattered light, and the colored spotlights provide colored light; together, these three constitute a triple visual interference system. This system subjectes the bird's visual system to multiple unpredictable sources of stimulation, effectively delaying the bird's visual and auditory adaptation to the deterrent signal.

[0021] A further embodiment of the present invention is that the reflective sphere includes a circular frame rotatably connected to a support plate, the lower half of the circular frame is provided with a plurality of reflective polygonal plates, and the upper half of the circular frame is provided with a transparent plate.

[0022] By adopting the above technical solution, the lower reflective polygonal plate is composed of multiple small facets at different angles. When the colored spotlight shines on the reflective polygonal plate, it reflects the natural light and colored spotlight rays that are shining on it in all directions when rotating, forming flashing and dynamic scattered light spots. The disordered reflected light of the reflective polygonal plate, together with the directional laser of the green laser and the single colored light of the colored spotlight, forms a "multi-dimensional change" in the visual signal, which increases the processing burden of the bird's visual system and makes it difficult for it to adapt.

[0023] The beneficial effects of this invention are as follows: When the electric drive mechanism drives the bowl-shaped rotating body to rotate, the friction between the bowl-shaped rotating body and the impact ball can also drive the elastic connecting rod and the impact ball to rotate, which in turn drives the reflective ball to rotate. On the one hand, the natural light is diffused to the surrounding orchard by the reflection of the spherical surface, forming a dynamic flashing strong light interference, which visually disrupts the birds' sense of security in their habitat. On the other hand, the centrifugal force generated by the rotation causes the impact ball at the end of the elastic connecting rod to swing randomly, making the timing and combination of the sound and light generators with different timbres and different flashing lights completely irregular. This superimposes the triple bird-repelling effects of dynamic reflection, random abnormal noise, and different colored light, forming a strong sensory stimulation and a continuous repelling effect. This effectively delays the birds' visual and auditory adaptation to the repelling signals, greatly improves the bird-repelling effect, and can effectively reduce the loss rate of fruit pecked by birds.

Detailed Implementation

[0027] The technical solution of the present invention will now be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Refer to Figure 1 , Figure 2 and Figure 5 This embodiment discloses a basic orchard bird deterrent device that is electrically driven and uses irregular sound and light to deter birds, solving the problems of fixed modes and easy adaptation by birds in traditional bird deterrent devices.

[0029] This embodiment includes a horizontally positioned housing 2 and an electrically driven mechanism disposed within the housing 2. A bowl-shaped rotating body 6 with its rim facing upwards is rotatably connected to the top of the housing 2. The bowl-shaped rotating body 6 is continuously rotated by the electrically driven mechanism. The embodiment also includes a bracket 1 for supporting the housing 2. The bowl-shaped rotating body 6 is mounted on the top of the housing 2 via multiple sets of rollers 4. The rollers 4 are evenly distributed circumferentially along the annular guide groove at the bottom of the bowl-shaped rotating body 6, significantly reducing rotational resistance through rolling friction and ensuring smooth and flexible rotation of the bowl-shaped rotating body 6. A support rod 18 is vertically fixed inside the housing 2, with its top end passing through the bowl-shaped rotating body 6 and rotatably connected to a reflective ball 9.

[0030] The bowl-shaped rotating body 6 has multiple through holes 7 annularly opened on its side wall. Each through hole 7 is embedded with an independent sound and light generator 8, and the light color and sound emitted by all the sound and light generators 8 are different. The timbre of each sound and light generator 8 is selected from different types of buzzing, bird calls, gunshots, and knocking sounds. The color of each flashing light is selected from different colors of red, blue, yellow, and green. The bottom of the reflector ball 9 is fixedly connected to multiple elastic connecting rods 11. The elastic connecting rods 11 are spring steel rods or rubber rods, which have the elastic recovery characteristic of producing random swing amplitude after impact. Each elastic connecting rod 11 has a rubber hollow impact ball 12 fixed at its end, which can be used in conjunction with the switch trigger part 803 of the sound and light generator 8 to trigger the operation.

[0031] The electric drive mechanism includes a circular housing 15 and an electric fan 14 fixedly connected to the bottom wall of the housing 2, and a transmission screw tube 19 fixedly connected to the bottom of the bowl-shaped rotating body 6 in the vertical direction. The support rod 18 passes through the transmission screw tube 19 and is fixedly connected to the housing 2. The bottom of the transmission screw tube 19 is rotatably connected to the circular housing 15. The air inlet end of the circular housing 15 is sealed to the air outlet end of the electric fan 14 for sending airflow into the circular housing 15 to drive the transmission screw tube 19 to rotate, thereby driving the bowl-shaped rotating body 6 to rotate. When the bowl-shaped rotating body 6 rotates on top of the box 2, the friction between the bowl-shaped rotating body 6 and the impact ball 12 also drives the elastic connecting rod 11 and the impact ball 12 to rotate, thereby driving the reflective ball 9 to rotate. On the one hand, the reflection of the spherical surface diffuses natural light into the surrounding orchard, forming a dynamic flashing strong light interference, visually disrupting the birds' sense of security in their habitat. On the other hand, the centrifugal force generated by the rotation causes the impact ball 12 at the end of the elastic connecting rod 11 to swing randomly, making the timing and combination of the sound and light generators 8 with different timbres and different colored lights completely irregular. Birds cannot form fixed adaptive memories, effectively preventing birds from developing habitual adaptations to fixed sound or visual patterns. The triple bird-repelling effect of dynamic reflection, random abnormal sounds, and different colored lights is superimposed to form a strong sensory stimulation, which can quickly disperse birds approaching the fruit trees without causing additional disturbance to the ecological environment around the orchard. It is suitable for planting scenarios of various cash crops, greatly improving the bird-repelling effect and effectively reducing the loss rate of fruit pecked by birds.

[0032] Example 2: Refer to Figure 1 and Figure 3 Based on Example 1, this embodiment refines and optimizes the specific structure and working logic of the sound and light generator 8 to achieve an enhanced bird-repelling effect with independent control of a single component, synchronous output of sound and light, and secondary diffusion of light.

[0033] The sound and light generator 8 in this embodiment includes a housing 801 fixedly installed on the inner wall of the bowl-shaped rotating body 6. An intermediate plate 802 is fixedly disposed inside the housing 801, dividing the inner cavity of the housing 801 into a trigger chamber and a working chamber. A switch triggering part 803 is an arc-shaped pressing plate, which serves as the trigger end of the sound and light generator. It is slidably mounted on the inner side wall of the trigger chamber of the housing 801 and can directly receive the impact trigger of the impact ball 12. A return spring is provided between the intermediate plate 802 and the switch triggering part 803 to assist in the reset of the switch triggering part 803. A piezoelectric switch 804 is installed on the side of the intermediate plate 802 near the triggering part, located on the sliding path of the arc-shaped pressing plate. A voice playback module 805 is installed on the other side of the intermediate plate 802. Multiple sets of sound-permeable holes 806 are opened at corresponding positions on the housing 801 to ensure efficient sound transmission. Simultaneously, multiple colored spotlights 807 are fixed to the intermediate plate 802, with all spotlights illuminating towards the top reflector ball 9.

[0034] The first storage battery 13 is removably installed inside the bowl-shaped rotating body 6, providing independent power to all sound and light generators 8. Each component does not interfere with each other and can start and stop independently. When the impact ball 12 presses the arc-shaped pressing plate, the pressing plate slides inward to touch the piezoelectric switch 804, simultaneously activating the working circuit of the voice playback module 805 and the colored spotlight 807. After the impact force disappears, the arc-shaped pressing plate is elastically reset by the piezoelectric switch 804, waiting for the next trigger.

[0035] Each voice playback module 805 has a preset independent working duration of 5-20 seconds, which can be adjusted through an internal timing circuit. The trigger times of different voice playback modules 805 are random, resulting in overlapping and interleaved sound playback start and end times, forming a stereo sound field with alternating rises and falls. At the same time, the exclusive colored light emitted by the colored spotlight 807 shines on the surface of the reflector sphere 9, and diffuses to the surroundings through secondary diffuse reflection by the reflector sphere 9, transforming the point light source into a large-area surface light source, greatly expanding the visual warning coverage area, and achieving dual-enhanced bird deterrence through sound and light.

[0036] Example 3: Refer to Figure 1 and Figure 4 Based on the above embodiments, this embodiment adds a laser irradiation component and an optimized reflective sphere structure to construct a multi-dynamic visual interference system, which makes up for the limited effective distance of conventional sound and light bird deterrence and achieves a combination of near and far, multi-dimensional visual deterrence.

[0037] In this embodiment, a laser irradiation assembly 16 is mounted at the top of the support rod 18. The laser irradiation assembly 16 includes a support plate 1602, an arc-shaped rod 1604, multiple green lasers 1605, a light control switch 1603, and a second battery 1601. The second battery 1601 is detachably installed at the bottom of the support plate and supplies power to the green lasers 1605. It is automatically turned on by the light control switch 1603 at dusk, night, or cloudy days, and the light control switch 1603 controls the power supply. The multiple green lasers 1605 are circumferentially fixed on the arc-shaped rod 1604 with their lamp heads facing outwards. They can emit highly recognizable green laser beams, forming clear light pillars on cloudy days, dusk, and night, creating a strong visual deterrent to birds flying at long distances.

[0038] The optimized reflective sphere 9 includes a circular frame 901 rotatably mounted on a support plate 1602. The upper half of the circular frame 901 is a transparent plate 902, and the lower half is arranged with multiple sets of reflective polygonal plates 903. The angles of each mirror surface of the polygonal circular frame 901 are different. During the rotation of the circular frame 901, natural light and colored spotlights can be reflected at multiple angles to produce dynamic flashing light spots whose brightness, position, and frequency change with the wind.

[0039] This embodiment constructs a triple visual bird deterrence system, comprising three visual signal sources: directional laser illumination, prism scattering, and fixed-point flashing of colored spotlights. The three visual signals exhibit completely different patterns of change, with no fixed correlation between them, thus significantly increasing the recognition burden on the bird's visual system and completely eliminating the possibility of birds adapting to a single visual stimulus. Simultaneously, this system achieves precise deterrence at close range through directional laser illumination, and provides long-range, wide-area protection through prism scattering and fixed-point flashing of colored spotlights, thus addressing bird deterrence needs at different spatial scales.

[0040] Example 4: Refer to Figure 1 and Figure 6 In this embodiment, a wind-driven mechanism and a matching sound amplification structure are added for situations with strong winds. The wind-driven mechanism saves energy, and the sound amplification structure expands the propagation of sound.

[0041] The wind-driven mechanism includes a support shaft 10 vertically fixed to the center of the top of the reflective sphere 9. Fan blades 17 are uniformly fixed to the outer surface of the support shaft 10. The fan blades 17 are directly fixed to the support shaft 10 at the center of the top of the reflective sphere 9, making the fan blades 17 and the reflective sphere 9 a single rotating component. The height of the fan blades 17 is set to be 20cm to 50cm higher than the fruit tree. The reflective sphere 9 has a hollow structure. The fan blades 17, the elastic connecting rod 11, and the impact ball 12 are made of lightweight rubber. Under natural wind, the fan blades 17 rotate, causing the reflective sphere 9 to rotate around the support rod 18. The elastic connecting rod 11 radiates outwards under centrifugal force. The reflective sphere 9 rotates in the opposite direction to the bowl-shaped rotating body 6. Multiple elastic connecting rods 11 cause the impact ball to randomly touch the switch trigger part 803 of each sound and light generator 8 at different times, angles, and forces. The reflective ball 9 serves as the rotation center, and the amplitude of the elastic connecting rod 11 hinged at its bottom being thrown outward under the action of centrifugal force is directly related to the rotation speed of the reflective ball 9. The rotation speed of the wind blade 17 changes in real time with the wind force, causing the swing amplitude and impact frequency of the impact ball 12 to change dynamically. This results in a non-linear coupling between the sound and light triggering sequence and the natural wind speed, further enhancing the unpredictability of the deterrent signal. This effectively prevents birds from adapting to the deterrent signal by memorizing specific rotation speed patterns, effectively preventing birds from developing adaptations and ensuring a stable bird deterrent effect over a long period of time.

[0042] The enclosure 2 is equipped with a third battery 3, and also includes an interconnected third battery 3, a wind speed sensor, a controller, and a comparator. When the wind speed detected by the wind speed sensor is greater than the threshold set by the comparator, the controller automatically turns off the electric fan 14. When the wind speed detected by the wind speed sensor is less than the threshold set by the comparator, the controller automatically turns on the electric fan 14. The third battery 3 provides unified power to the electric fan 14, the wind speed sensor, the controller, the comparator, and the multiple sound amplifiers 5 distributed in a circular array on the top of the enclosure 2, realizing the automatic turning on and off of the electric fan 14 for convenient use.

[0043] Example 5: Refer to Figure 6 and Figure 7This embodiment focuses on the durability requirements of outdoor use of the equipment, and adds a cross-shaped solar panel 21 and an arc-shaped transparent panel 20. The contact points of the solar panel 21 and the arc-shaped transparent panel 20 are sealed together. On the one hand, the solar panel 21 supplies power to the aforementioned battery through the controller, ensuring a continuous supply of power. On the other hand, the solar panel 21 and the arc-shaped transparent panel 20 form a rainproof cover, which can effectively block rainwater, dew, frost and snow, prevent rainwater from seeping into the internal cavity of the bowl-shaped rotating body 6, protect the internal electrical components such as the first battery 13 and the sound and light generator 8, prevent the components from getting damp, short-circuiting, or corroding and being damaged, achieve stable operation under severe weather conditions such as rain and snow, extend the service life of the equipment, ensure uninterrupted bird control throughout the year, prevent birds from adapting to the bird control stimulus by using the equipment's shutdown period, maintain the effect of breaking the birds' adaptation throughout the process, and is suitable for the year-round open-air use scenario in orchards.

[0044] The present invention has the following effects: When the electric drive mechanism drives the bowl-shaped rotating body 6 to rotate on the top of the box 2, the friction between the bowl-shaped rotating body 6 and the impact ball 12 can also drive the elastic connecting rod 11 and the impact ball 12 to rotate, thereby driving the reflective ball 9 to rotate. On the one hand, the natural light is diffused to the surrounding orchard by the reflection of the spherical surface, forming a dynamic flashing strong light interference, which visually breaks the birds' sense of security in their habitat. On the other hand, the centrifugal force generated by the rotation makes the impact ball 12 at the end of the elastic connecting rod 11 swing randomly, so that the timing and combination of the sound and light generators 8 with different timbres and different colored lights are triggered is completely irregular. The triple bird-repelling effect of dynamic reflection, random abnormal noise and different colored light is superimposed to form a strong sensory stimulation, which effectively delays the birds' visual and auditory adaptation to the driving signal, greatly improves the bird-repelling effect, and can effectively reduce the loss rate of fruit pecked by birds.
