Description

Technical Field

[0001] This application belongs to the technical field of bird deterrence devices, specifically relating to a hemispherical mirror-reflective bird deterrence device and a bird deterrence method. Background Technology

[0002] When birds perch, nest, or defecate near power transmission and distribution lines, towers, crossarms, insulators, and outdoor equipment in substations, they can cause a decrease in insulation performance, flashover, phase-to-phase short circuits, or grounding faults, affecting the safe and stable operation of power equipment. Therefore, installing bird deterrent devices near power facilities is a common technical measure to reduce the risk of bird damage.

[0003] Currently, bird deterrent devices for power lines mainly include zoning devices, reflective devices, sound and light devices, and scent devices. Among them, reflective devices typically use reflectors, reflective sheets, and reflective covers to create visual stimuli to reduce birds' approach or dwelling. Because these devices are relatively simple in structure, easy to install, and cause less harm to birds, they are widely used in outdoor power equipment scenarios such as transmission and distribution lines.

[0004] While the aforementioned bird deterrent devices can reduce the probability of birds lingering and nesting near power facilities to some extent, they still have certain shortcomings in long-term outdoor use. For reflective bird deterrents, the reflected light path variation of common products is relatively simple. Under different lighting conditions and with different bird approach directions, the visual stimulation effect is prone to unevenness, and the bird deterrent effect is not stable in some areas. As the usage time increases, the relatively fixed visual stimulation pattern can also easily lead to birds gradually adapting, resulting in a decrease in the sustained deterrent effect.

[0005] For bird deterrents that rely on natural wind, their working condition is easily affected by wind conditions. In windless or lightly windy weather, the dynamic bird deterrent effect of the device is weak; in outdoor environments exposed to wind and rain for a long time, rotating parts, connecting parts and supporting structures are prone to wear, corrosion or aging, which reduces the operational stability and service life of the device.

[0006] For bird deterrents installed high on power transmission lines or towers, cleaning and maintenance are also important factors affecting their effectiveness. Because bird deterrents are usually installed at high positions, manual cleaning, disassembly, maintenance, or replacement of parts is difficult, costly, and carries certain risks associated with working at height.

[0007] In addition, traditional reflective bird repellers are usually highly dependent on natural lighting conditions. In low-light environments such as rain, fog, haze, and dusk, the reflectivity decreases, and the bird-repelling effect is easily weakened.

[0008] Therefore, for outdoor high-altitude applications such as power transmission and distribution lines, it is still necessary to further improve the bird deterrence devices for power lines to enhance their bird deterrence stability and ensure their continued effectiveness under different lighting, wind, and pollution conditions. Summary of the Invention

[0009] The purpose of this invention is to provide a hemispherical mirror-reflective bird deterrent device and method to solve the problems of existing reflective bird deterrent devices, such as single reflected light path, weak dynamic bird deterrent effect, and insufficient long-term stability of moving structure, thereby improving the bird deterrent stability and continuous use effect of the reflective bird deterrent device.

[0010] To achieve the above objectives, the present invention employs the following technical solution: According to one aspect of the present invention, a hemispherical mirror-reflective bird deterrent device is provided, comprising: A support assembly, comprising a base and a support column disposed on the base; A hemispherical reflector is oscillatingly mounted on a support column. The hemispherical reflector has a mirror-like reflective surface and forms an inner cavity. The built-in reflective component is located in the inner cavity of the hemispherical reflective cover. The built-in reflective component includes multiple arc-shaped reflective elements distributed circumferentially along the hemispherical reflective cover. The multiple arc-shaped reflective elements cooperate with the hemispherical reflective cover to form a multi-path reflected light path. A swing limiting component is disposed between the support column and the hemispherical reflector. The swing limiting component includes an arc-shaped limiting track disposed on the hemispherical reflector and a limiting pin disposed on the support column. The limiting pin extends into the arc-shaped limiting track and can slide relative to the arc-shaped limiting track when the hemispherical reflector swings, so as to limit the maximum swing angle of the hemispherical reflector relative to the support column.

[0011] By employing the above technical solution, the mirror-like reflective surface of the hemispherical reflector, in conjunction with multiple arc-shaped reflective elements housed within its inner cavity, can form a multi-path reflected light path, thereby improving the problem of the relatively singular variation mode of reflected light path in reflective bird deterrent devices. Furthermore, the swaying of the hemispherical reflector relative to the support column under wind force allows for dynamic sweeping of the multi-path reflected light path, enhancing the dynamic visual stimulation effect on birds. Finally, the use of an arc-shaped limiting track and limiting pins to limit the maximum sway angle of the hemispherical reflector reduces the impact of excessive swaying on the stability of the connecting structure, thus improving the reliability of the device in outdoor windy environments.

[0012] Furthermore, the hemispherical reflector is made of fiberglass, and the mirror-reflective surface includes a chemically plated nickel polishing layer, a metal reflective layer, a reflective film, or an ultraviolet reflective film formed on the outer or inner surface of the hemispherical reflector. Thus, by forming a mirror-reflective surface on the hemispherical reflector, the hemispherical reflector can participate in reflection and protect the built-in reflective components, thereby improving the overall stability and anti-fouling capability of the reflective structure.

[0013] According to one embodiment of the present invention, multiple arc-shaped reflectors are evenly distributed along the circumference of the hemispherical reflector, and the angle formed between two adjacent arc-shaped reflectors and the center of the hemispherical reflector is 30°-120°.

[0014] Therefore, by evenly distributing multiple arc-shaped reflectors along the circumference of the hemispherical reflector, a more balanced reflection distribution can be formed in the circumference, thereby improving the stability of bird-repelling visual stimuli in different directions. By forming an angle of 30°-120° between two adjacent arc-shaped reflectors and the center of the hemispherical reflector, an appropriate spatial distribution relationship can be formed between adjacent reflectors, thereby enhancing the spatial coverage effect of the multi-path reflected light path and reducing local blind spots.

[0015] Furthermore, the number of curved reflectors is 3-12.

[0016] Furthermore, there are 6 curved reflectors, and the angle between two adjacent curved reflectors and the center of the hemispherical reflector is 60°.

[0017] According to one embodiment of the present invention, the arc-shaped reflector is connected to the inner side of the hemispherical reflector via a movable connection structure. Thus, the arc-shaped reflector can change its reflection angle relative to the hemispherical reflector, thereby increasing the degree of variation in the reflected light path.

[0018] The movable connection structure can be configured as a hinge, pivot, flexible connector or elastic connector as needed, so that the arc-shaped reflector can change the reflection angle relative to the hemispherical reflector and improve the structural adaptability of the built-in reflector assembly.

[0019] According to one embodiment of the present invention, the movable connection structure is an asymmetrical linkage component, which includes an elastic hinge and an eccentric counterweight. The elastic hinge connects the arc-shaped reflector and the hemispherical reflector, and the eccentric counterweight is disposed on the arc-shaped reflector.

[0020] By connecting the arc-shaped reflector and the hemispherical reflector with an elastic hinge, the arc-shaped reflector can be reset. By setting an eccentric counterweight on the arc-shaped reflector, the arc-shaped reflector can be deflected relative to the hemispherical reflector when the hemispherical reflector swings, thereby superimposing to form a stroboscopic or fragmented reflective light path.

[0021] According to one embodiment of the present invention, the elastic stiffness of the elastic hinge is 0.3 N / mm-0.6 N / mm, and the reset response time is no more than 50 ms; the mass of the eccentric counterweight is 1.8 g-2.5 g, and the centroid eccentricity is 3.5 mm-5 mm. This causes the arc-shaped reflector to form a relatively lagging or leading additional deflection during the swinging and oscillating of the housing, thereby improving the randomness of the optical path changes.

[0022] According to one embodiment of the present invention, the swing limiting assembly limits the maximum swing angle of the hemispherical reflector relative to the support column to 10°-45° on one side.

[0023] In this way, it is possible to suppress excessive oscillation while ensuring the dynamic oscillation of the hemispherical reflector, thus balancing the dynamic reflective effect and the long-term reliability of the moving structure.

[0024] Preferably, the swing limiting component limits the maximum swing angle of the hemispherical reflector relative to the support column to 30° on one side.

[0025] According to one embodiment of the present invention, an arc-shaped limiting track is disposed on the top or inner top of the hemispherical reflector, a limiting pin is disposed on the top of the support column, and the end of the arc-shaped limiting track is used to abut against the limiting pin when the hemispherical reflector swings to a preset maximum swing angle.

[0026] This allows the swing limiting component to be located in the connection area between the hemispherical reflector and the support column, thereby improving the compactness of the limiting structure arrangement; when the hemispherical reflector swings to the preset maximum swing angle, the end of the arc-shaped limiting track abuts against the limiting pin to form a clear mechanical stop, thereby improving the reliability of the swing limiting.

[0027] Furthermore, the limiting pin is an adjustable damping limiting pin, and a damping body and an adjusting nut are provided between the limiting pin and the support. The adjusting nut is used to adjust the preload of the damping body to change the initial damping force of the limiting pin.

[0028] By adjusting the preload of the damper, the cover can be kept to swing flexibly when the wind is light, and the instantaneous rigid impact can be transformed into a flexible buffer when the wind is strong, thereby reducing structural damage caused by limiting impact.

[0029] Furthermore, elastic buffers or wear-resistant limiting pads are provided at the ends of the arc-shaped limiting track. This reduces the impact when the limiting pin collides with the end of the arc-shaped limiting track, improving the reliability for long-term outdoor use.

[0030] According to one embodiment of the present invention, the hemispherical mirror reflective bird deterrent device further includes a low-illuminance supplementary lighting component, which includes a supplementary light source. The supplementary light source is disposed toward the built-in reflective component, and the light emitted by the supplementary light source is reflected by the arc-shaped reflector to form a bird deterrent light path.

[0031] In this way, the low-light supplementary lighting component works in conjunction with the hemispherical reflector and the built-in reflector. By aligning the supplementary light source with the built-in reflector, the light emitted by the supplementary light source can enter the hemispherical reflector and be reflected by the arc-shaped reflector to form a bird-repelling light path, thereby improving the visual bird-repelling effect in low-light environments.

[0032] The supplementary light source works in conjunction with solar power components and energy storage batteries; in this way, the solar power components can be used to supplement the energy storage batteries, and the energy storage batteries can be used to power the supplementary light source when needed, thereby improving the applicability of the device in outdoor scenarios without external power supply.

[0033] According to one embodiment of the present invention, the low-illuminance supplementary lighting component further includes an ambient light detector, which is used to trigger the supplementary light source to operate when the ambient light intensity is lower than a preset threshold.

[0034] In this way, it can automatically supplement light according to the external lighting conditions, thereby reducing unnecessary work of the supplementary light source when the light is sufficient and improving the targeted use of supplementary light.

[0035] Furthermore, the preset threshold is 10000 Lux, and the supplementary light source includes a string of LED beads set on the base, with the emission wavelength of the LED beads being 600nm-760nm.

[0036] According to one embodiment of the present invention, a functional component mounting part is provided on the base, which is used for detachably mounting cleaning components or auxiliary bird deterrent components.

[0037] The functional component installation section allows for the detachable installation of cleaning components or auxiliary bird deterrent components, thereby improving the convenience of functional expansion and maintenance replacement of the device according to the site environment.

[0038] Furthermore, the cleaning component contacts the outer surface of the hemispherical reflector and sweeps the outer surface of the hemispherical reflector when it is swayed by the wind.

[0039] Furthermore, cleaning components include soft-bristled brushes, silicone squeegees, or flexible wiping pads.

[0040] By bringing cleaning components such as soft brushes, silicone squeegees, or flexible wiping pads into contact with the outer surface of the hemispherical reflector, the outer surface can be swept as the hemispherical reflector swings, thereby reducing the impact of contaminants such as dust, rainwater residue, or bird droppings on the mirror reflection effect. By utilizing the cleaning action generated by the swinging of the hemispherical reflector under wind force, the need for additional cleaning drive structures can be reduced, thus lowering the maintenance difficulty in high-altitude installation scenarios.

[0041] Furthermore, auxiliary bird deterrents include ribbons or scented bird repellents.

[0042] Furthermore, the base includes a mounting and fixing part for connecting to the crossarm, pole or tower of the power transmission and distribution line, wherein the mounting and fixing part is a clamping structure, a binding structure or a magnetic attraction structure.

[0043] According to a second aspect of the present invention, a bird deterrent method is provided, the bird deterrent method being based on the above-described hemispherical mirror-reflective bird deterrent device, comprising the following steps: The incident light is directed to the hemispherical reflector and multiple curved reflectors, and a multi-path reflected light path is formed by the cooperation of the hemispherical reflector and the multiple curved reflectors. The hemispherical reflector sways relative to the support column under the action of wind, causing the multi-path reflected light path to be dynamically swept along with the sway of the hemispherical reflector. During the swinging process of the hemispherical reflector, the limiting pin slides relative to the arc-shaped limiting track, and when the hemispherical reflector swings to the preset maximum swing angle, the limiting pin and the arc-shaped limiting track restrict the hemispherical reflector from continuing to swing. By using dynamically swept multipath reflected light paths to create visual stimulation for birds, bird deterrence can be achieved.

[0044] Compared with the prior art, this application has the following beneficial effects: 1. The present invention uses a hemispherical reflector with a mirror-like reflective surface and sets multiple arc-shaped reflective elements distributed circumferentially in the inner cavity of the hemispherical reflector. This enables the incident light to form a multi-path reflected light path between the hemispherical reflector and the arc-shaped reflective elements, thereby improving the problem of monotonous visual stimulation caused by single-path or few-path reflection, and increasing the degree of variation of bird deterrent light path and spatial coverage effect.

[0045] 2. The present invention, by oscillatingly mounting a hemispherical reflector on a support column, enables the multi-path reflected light path to dynamically sweep with the oscillation of the hemispherical reflector, thereby enhancing the dynamic change effect of the bird-repelling light path, improving the continuous visual stimulation ability of the reflective bird-repelling device on birds, and improving the dynamic bird-repelling effect.

[0046] 3. By setting a swing limiting component between the support column and the hemispherical reflector, and using an arc-shaped limiting track and a limiting pin to limit the maximum swing angle of the hemispherical reflector, the present invention can suppress excessive swing while forming dynamic sweeping reflection, thereby improving the structural stability and long-term reliability of the device in outdoor windy environments.

[0047] 4. This invention utilizes multiple arc-shaped reflectors evenly distributed circumferentially along a hemispherical reflector housing to improve the uniformity of reflection distribution in different directions, thereby enhancing the stability of the device in deterring birds from approaching from various directions. Furthermore, the arc-shaped reflectors are connected to the inner side of the hemispherical reflector housing via a movable connection structure, allowing the reflectors to change their reflection angle relative to the hemispherical reflector housing, further enhancing the variability of the reflected light path. An asymmetrical linkage is formed by an elastic hinge and an eccentric counterweight, enabling the arc-shaped reflectors to produce additional deflection or momentary jitter during the swinging and limiting return of the hemispherical reflector housing, further enhancing the randomness and fragmentation effect of the reflected light path.

[0048] 5. The present invention, through the cooperation of adjustable damping limit pin, damping body and adjusting nut, can buffer the limit impact according to the wind force, thereby improving the durability of dynamic wind swing structure. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] Example 1 This embodiment provides a hemispherical mirror-reflective bird deterrent device, suitable for outdoor power facilities such as power transmission and distribution lines, towers, crossarms, insulators, and outdoor equipment in substations. Figure 1 As shown, this bird deterrent device includes a support assembly, a hemispherical reflector 20, a built-in reflector 30, and a swing limiting assembly 40.

[0054] The support assembly is used to support the hemispherical reflector 20, the built-in reflector 30, and related auxiliary functional components. The support assembly includes a base 11 and a support column 12 disposed on the base 11. The base 11 can be a plate base 11, a clamping base 11, a magnetic base 11, or a binding base 11.

[0055] Specifically, the base 11 is provided with a mounting and fixing part, which can be one or more combinations of U-shaped groove, clamp, bolt hole, binding hole or magnetic block, used to fix the base 11 to the crossarm, tower component or other power equipment support structure.

[0056] The support column 12 is positioned above the base 11. The lower end of the support column 12 can be connected to the base 11 by welding, bolting, riveting, plugging and locking, or integral molding. The support column 12 extends vertically upward, and its upper end is used to support the hemispherical reflector 20 and cooperate with the swing limiting assembly 40.

[0057] The hemispherical reflector 20 is pivotally mounted on the top of the support column 12. The hemispherical reflector 20 has a specular reflective surface facing the external environment and forms an inner cavity therein. The specular reflective surface can be disposed on the outer surface of the hemispherical reflector 20, or on the inner surface of the hemispherical reflector 20, or on at least one of the outer and inner surfaces.

[0058] Specifically, the hemispherical reflector 20 is made of fiberglass, engineering plastics, thin metal shells, or composite materials, and the mirror reflective surface is a chemically plated nickel polished layer, a metal reflective layer, a reflective film, or an ultraviolet reflective film. By giving the hemispherical reflector 20 its own mirror reflective surface, the hemispherical reflector 20 serves as both an external reflective structure and an external cover for the built-in reflective component 30.

[0059] In this embodiment, the hemispherical reflector 20 has a radius of 12.5 cm, a thickness of approximately 2-3 mm, and a weight of approximately 80 g. The hemispherical reflector 20 is made of fiberglass, and its mirror-reflective surface is a chemically plated nickel-polished layer, which is applied to both the inner and outer surfaces of the hemispherical reflector 20. Figure 2 This is a schematic diagram of the reflective space coverage area of ​​the mirror reflective surface. It can be seen that the hemispherical reflective cover 20 of this embodiment has a 360° coverage range of the reflective space of its built-in and external mirror reflective surfaces, which can achieve full space coverage.

[0060] The hemispherical reflector 20 and the support column 12 can be connected by a pivot, hinge, ball joint, universal joint, or flexible connection to allow the hemispherical reflector 20 to swing relative to the support column 12 within a certain angle range. In one specific embodiment, a connecting seat is provided on the top inner side of the hemispherical reflector 20, and a connecting lug is provided on the top of the support column 12. The connecting seat and the connecting lug are hinged by a transverse pivot, allowing the hemispherical reflector 20 to swing relative to the support column 12 under wind force. In this embodiment, the hemispherical reflector 20 is connected to the top of the support column 12 via a universal ball joint connector, allowing the hemispherical reflector 20 to swing in controlled directions.

[0061] An internal reflective assembly 30 is disposed within the cavity of the hemispherical reflector 20. The internal reflective assembly 30 includes multiple arc-shaped reflectors 31, which are distributed circumferentially along the hemispherical reflector 20. The arc-shaped reflectors 31 can be arc-shaped lenses, arc-shaped reflectors, arc-shaped metal reflective sheets, or arc-shaped sheet-like components coated with a reflective film. The reflective surface of each arc-shaped reflector 31 can face the central region of the hemispherical reflector 20, or it can form a certain tilt angle relative to the radial direction of the hemispherical reflector 20, so as to form a multi-path reflected light path together with the hemispherical reflector 20.

[0062] Multiple arc-shaped reflectors 31 are evenly distributed along the circumference of the hemispherical reflector 20. The number of arc-shaped reflectors 31 can be 3-12; the angle formed between two adjacent arc-shaped reflectors 31 and the center of the hemispherical reflector 20 is 30°-120°. Figure 3 As shown, in this embodiment, there are 6 arc-shaped reflectors 31, and the angle formed between two adjacent arc-shaped reflectors 31 and the center of the hemispherical reflector 20 is 60°. Through circumferential distribution, multiple arc-shaped reflectors 31 can form a surrounding reflection distribution in the inner cavity of the hemispherical reflector 20, so that external incident light or light emitted by the supplementary light source 51 can be reflected in multiple directions.

[0063] Furthermore, the arc-shaped reflector 31 is connected to the inner side of the hemispherical reflector 20 via a movable connection structure. The movable connection structure can be a hinge, a pivot, a flexible connector, or an elastic connector. In one specific embodiment, the upper edge or one side edge of each arc-shaped reflector 31 is connected to the inner wall of the hemispherical reflector 20 via a small hinge, allowing the arc-shaped reflector 31 to rotate relative to the hemispherical reflector 20 within a predetermined angle range. In another specific embodiment, each arc-shaped reflector 31 is pivotally connected to a mounting base inside the hemispherical reflector 20 via a pivot, the axis of which can extend vertically, laterally, or tangentially relative to the hemispherical reflector 20. In yet another embodiment, the arc-shaped reflector 31 is connected to the inner side of the hemispherical reflector 20 via a flexible or elastic connector, allowing the arc-shaped reflector 31 to undergo minute angular changes when the hemispherical reflector 20 swings or is disturbed by wind. By setting an active connection structure, the arc-shaped reflector 31 can change the reflection angle relative to the hemispherical reflector 20, thereby increasing the degree of variation in the reflected light path.

[0064] A swing limiting component 40 is disposed between the support column 12 and the hemispherical reflector 20. The swing limiting component 40 includes an arc-shaped limiting track 41 and a limiting pin 42. The arc-shaped limiting track 41 is disposed on the hemispherical reflector 20, and the limiting pin 42 is disposed on the support column 12. The limiting pin 42 extends into the arc-shaped limiting track 41 and can slide relative to the arc-shaped limiting track 41 when the hemispherical reflector 20 is swayed by wind force, so as to limit the maximum swing angle of the hemispherical reflector 20 relative to the support column 12.

[0065] Specifically, the arc-shaped limiting track 41 is located on the inner top of the hemispherical reflector 20, and the arc-shaped limiting track 41 swings synchronously with the hemispherical reflector 20; the limiting pin 42 is fixedly installed on the top of the support column 12, and the upper end of the limiting pin 42 extends into the track groove of the arc-shaped limiting track 41. The arc-shaped limiting track 41 can be an arc-shaped groove, an arc-shaped guide rail, or a limiting component with an arc-shaped guide channel. The limiting pin 42 can be a cylindrical pin, a bolt pin, a pin with rollers, or a positioning pin with a wear-resistant sleeve. The limiting pin 42 and the arc-shaped limiting track 41 can be clearance-fitted, allowing the limiting pin 42 to slide relative to the arc-shaped limiting track 41. When the hemispherical reflector 20 swings to one side under the action of wind, the arc-shaped limiting track 41 moves with the hemispherical reflector 20, and the limiting pin 42 slides relative to it in the arc-shaped limiting track 41. When the hemispherical reflector 20 swings to the preset maximum swing angle, the end of the arc-shaped limiting track 41 abuts against the limiting pin 42 to form a mechanical stop, thereby limiting the hemispherical reflector 20 from continuing to swing.

[0066] In this embodiment, the limiting pin 42 is also equipped with a limiting piece 43, which is sleeved on the outside of the limiting pin 42 and is an arc-shaped structure with the opening facing upward. The end of the limiting piece 43 extends into the track groove of the arc-shaped limiting track 41, and during the swinging of the arc-shaped limiting track 41 with the hemispherical reflector 20, the outer edge of the limiting piece 43 abuts against the end of the arc-shaped limiting track 41, forming a rigid mechanical block. An elastic buffer or wear-resistant limiting pad is provided at the end of the arc-shaped limiting track 41 to withstand the impact when the small limiting pin 42 collides with the end of the arc-shaped limiting track 41, thereby improving the reliability of long-term outdoor use.

[0067] The swing limiting component 40 limits the maximum swing angle of the hemispherical reflector 20 relative to the support column 12 on one side to 10°-45°. In this embodiment, the maximum swing angle on one side is 30°. See also Figure 4 and Figure 5 The diagrams show the hemispherical reflector 20 swinging to its maximum angle on one side and in a non-swinging state, respectively. This allows the hemispherical reflector 20 to dynamically swing under natural wind conditions, while avoiding excessive swing amplitude that could lead to fatigue at connection points, structural collisions, or the reflector detaching.

[0068] The hemispherical mirror-reflective bird deterrent device also includes a low-light supplementary lighting component 50, used to provide supplementary light source 51 for the device in low-light environments. See also Figure 6 The low-light supplementary lighting component 50 includes a supplementary light source 51, which is positioned towards the built-in reflective component 30, so that the light emitted by the supplementary light source 51 is reflected by the arc-shaped reflector 31 to form a bird-repelling light path. In one specific embodiment, the supplementary light source 51 is a string of LED beads, which is disposed on the base 11 or the lower part of the support column 12, and arranged towards the inner cavity of the hemispherical reflector 20 and the arc-shaped reflector 31. The LED bead string can be distributed circumferentially along the base 11 or spaced along the outer periphery of the support column 12, so that its emitted light can illuminate the arc-shaped reflector 31. In this embodiment, the LED bead string is wound around the periphery of the support column 12, and 10-15 LED beads can be set, each with a power of 0.5W. The emission wavelength of the LED bead string can be 600nm-760nm to form a red-orange light path with strong visual stimulation, possessing strong atmospheric penetration under low-light conditions such as fog, haze, and dusk.

[0069] The supplementary light source 51 works in conjunction with the solar power supply component 52 and the energy storage battery. The solar power supply component 52 can be a solar panel, disposed on the upper surface of the base 11, the side of the base 11, or the non-reflective area outside the hemispherical reflector 20. The energy storage battery can be a lithium battery, nickel-metal hydride battery, or supercapacitor, etc., and is installed in a waterproof battery compartment inside the base 11. The solar power supply component 52 is electrically connected to the energy storage battery via a waterproof wiring harness, and the energy storage battery supplies power to the supplementary light source 51 through an electronic control unit. The electronic control unit may include a charge and discharge protection circuit, a switch control circuit, and waterproof connectors. With this structure, under daylight conditions, the solar power supply component 52 charges the energy storage battery, and under low light conditions, the energy storage battery supplies power to the supplementary light source 51. In this embodiment, the solar power supply component 52 includes two solar panels disposed on the upper surface of the base 11, with dimensions of 90mm × 120mm; the upper surface of the base 11 is provided with a mounting groove 13 for cooperating with the solar panels; the energy storage battery is a solar-chargeable lithium battery with a capacity of 3000mAh × 3 and a voltage of 3.2V. The conversion efficiency of the solar panel and the solar-charged lithium battery is over 85%. It stores energy on sunny days and discharges on cloudy days, with a discharge time of up to 48 hours when fully charged. Experiments show that it can provide 3-5 days of continuous use under typical cloudy / rainy weather conditions.

[0070] The low-light supplementary lighting component 50 also includes an ambient light detector, which triggers the supplementary light source 51 to operate when the ambient light intensity is below a preset threshold. The ambient light detector can be a photoresistor, photodiode, illuminance sensor, or other components capable of detecting ambient light intensity. The ambient light detector is positioned on the base 11, the support column 12, or in a location outside the hemispherical reflector 20 that is not easily obstructed, and is electrically connected to the electronic control unit. When the ambient light detector detects that the ambient light intensity is below the preset threshold, it outputs a trigger signal to the electronic control unit, which then controls the supplementary light source 51 to operate. When the ambient light intensity is above the preset threshold, the electronic control unit controls the supplementary light source 51 to turn off or reduce its brightness. Furthermore, the preset threshold can be set to 10000 Lux. Through the cooperation of the ambient light detector and the electronic control unit, supplementary lighting can be automatically activated according to the external lighting conditions.

[0071] Thus, the multi-path reflected light path of the hemispherical mirror bird deterrent device in this embodiment under natural light illumination is shown in the following figure. Figure 7 See the multipath reflection light path under the illumination of supplementary light source 51. Figure 8 , Figure 7 and Figure 8 Several possible reflected light paths are given in the text. Figure 7 The dashed line represents an example of the path of a natural light source, while the solid line represents an example of the path of refracted light after passing through the arc-shaped reflector 31. The figure shows examples of seven different reflected light paths. Figure 8 The dashed line represents an example of the path of the supplementary light source, while the solid line represents an example of the path of the refracted light after passing through the arc-shaped reflector 31. The figure shows six examples of reflected light paths. It is evident that this bird-repelling device can fully utilize natural light reflection and actively supplement light as needed. Through the coordination of multi-spectral reflection, it can provide various visual stimuli for birds in terms of light intensity, spectrum, and mode. The hemispherical reflector 20, in conjunction with the swing limiting component 40, can swing naturally and randomly, increasing the complexity of the light path's trajectory. Thus, under the combined effect of dynamic, variable light and random movement, it can continuously and effectively disturb birds, preventing them from developing habitual adaptations, improving the dynamic bird-repelling effect, and ensuring the stability of the bird-repelling mechanism.

[0072] In addition, a functional component mounting section 60 is provided on the base 11, which is used for the detachable installation of cleaning components or auxiliary bird-repelling components. The functional component mounting section 60 can be a ring mounting ring, a wire loop, a slot, a socket, a binding hole, a clamping seat, or a plug-in seat. In one specific embodiment, the functional component mounting section 60 is a ring mounting ring located above the base 11, and the cleaning component or auxiliary bird-repelling component is detachably fixed to the functional component mounting section 60 by plastic straps, buckles, screws, elastic clips, or plug-in structures. By providing the functional component mounting section 60, different functional components can be selected for installation according to the bird damage situation, pollution situation, or maintenance requirements at the installation site.

[0073] The cleaning component can be a soft brush, a silicone squeegee, or a flexible wiping pad. The cleaning component is mounted on the functional component mounting portion 60, with its free end contacting the outer surface of the hemispherical reflector 20. In one specific embodiment, the cleaning component is positioned above the base 11 and extends upwards, with its upper end abutting the lower outer surface of the hemispherical reflector 20. When the hemispherical reflector 20 oscillates under wind force, the outer surface of the hemispherical reflector 20 moves relative to the cleaning component, causing the cleaning component to sweep the outer surface of the hemispherical reflector 20, thereby reducing the impact of dust, bird droppings, rainwater residue, or other contaminants on the mirror reflective surface. The contact pressure between the cleaning component and the hemispherical reflector 20 can be adjusted by changing the mounting position, tilt angle, or extension length of the cleaning component on the functional component mounting portion 60. To avoid scratching the mirror reflective surface, the cleaning component is preferably made of a flexible material.

[0074] The auxiliary bird deterrent can be a colored ribbon, a reflective ribbon, a scented bird repellent carrier, or other visual or scent-based bird deterrent components. Generally, the auxiliary bird deterrent can be a colored ribbon, which is fixed to the functional component mounting part 60 by binding and can swing in the wind to create an auxiliary visual stimulus. The auxiliary bird deterrent can also be a scented bird repellent carrier, which is detachably mounted on the functional component mounting part 60 to release bird-repelling odors. The auxiliary bird deterrent can be installed simultaneously with the cleaning component, or selectively installed as needed.

[0075] The hemispherical mirror-reflective bird deterrent device in this embodiment employs a dynamic wind-swept design combining a hemispherical mirror outer cover with multiple internal arc-shaped mirror groups, generating thousands of optical path variations. When the hemispherical reflector 20 sways with the wind, these optical paths dynamically sweep in the horizontal and vertical directions, collectively forming a dynamically changing optical network, achieving 360° full-space coverage and reducing the number of times birds stop to land by 400%.

[0076] The low-light supplemental lighting component 50 completely solves the core pain point of traditional bird deterrent products, which rely on sunlight and fail in cloudy, rainy, twilight, and foggy weather. The low-light supplemental lighting component 50 automatically activates a string of LED beads of a specific wavelength when light is insufficient. This wavelength of light not only provides strong visual stimulation for birds but also has strong atmospheric penetration. Combined with the solar power supply component 52 and energy storage battery, it achieves self-sufficiency in energy and stable, continuous operation under all weather conditions.

[0077] Example 2 This embodiment provides a hemispherical mirror-reflective bird deterrent device, which differs from Embodiment 1 in that: In this embodiment, the active linkage structure is an asymmetrical linkage. This asymmetrical linkage includes an elastic hinge and an eccentric counterweight. The elastic hinge connects the arc-shaped reflector 31 to the inner wall of the hemispherical reflector 20. The eccentric counterweight is fixed to one edge of the arc-shaped reflector 31, causing the center of mass of the eccentric counterweight to deviate from the geometric center of the arc-shaped reflector 31. See also... Figure 9 The elastic hinge includes two hinged spring pieces 71. The spring pieces 71 can be made of stainless steel memory spring pieces with an elastic stiffness of 0.3N / mm-0.6N / mm and a reset response time of no more than 50ms. The mass of the eccentric counterweight is 1.8g-2.5g and the center of gravity eccentricity is 3.5mm-5mm.

[0078] When the hemispherical reflector 20 swings, the arc-shaped reflector 31, under the influence of inertia and the eccentric counterweight, undergoes an additional deflection relative to the hemispherical reflector 20, either lagging or leading. In this embodiment, the absolute value of the additional deflection angle of the arc-shaped reflector 31 relative to the hemispherical reflector 20 is 8°-15°, and the deflection angular velocity difference is not less than 25 rad / s. When the hemispherical reflector 20 triggers the swing limit, stops instantaneously, or swings back, the elastic hinge releases stored energy and drives the arc-shaped reflector 31 to generate a high-frequency, small-amplitude instantaneous jitter. The jitter frequency can be 30Hz-80Hz, and the micro-amplitude can be 0.2mm-0.8mm. This superimposes irregular flickering and multi-directional fragmented reflection effects onto the overall sweep of the hemispherical reflector 20, increasing the randomness of the light path and reducing birds' adaptation to fixed visual stimuli.

[0079] In addition, the limiting pin 42 is an adjustable damping limiting pin. A damping body and an adjusting nut are provided between the limiting pin 42 and the support column 12. The damping body can be a spring, a rubber damping sleeve, or an elastic buffer pad. The adjusting nut is threaded to the limiting pin 42 or the support column 12. By rotating the adjusting nut, the compression of the damping body can be changed, thereby adjusting the initial damping force of the limiting pin 42. When the wind force is weak, the hemispherical reflector 20 can swing under a small wind force, and the limiting pin 42 basically does not compress the damping body, allowing the hemispherical reflector 20 to swing flexibly. When the wind force is strong, the impact force generated when the hemispherical reflector 20 swings to the limiting position compresses the damping body, transforming the instantaneous rigid impact into a buffered flexible limiting, thereby reducing the risk of structural damage.

[0080] The hemispherical mirror-reflective bird deterrent device of this embodiment also includes an acoustic-optical synergy component. This component includes a microcontroller and a piezoelectric buzzer driven by the microcontroller. The microcontroller can be installed inside the base 11 or in a waterproof control compartment at the bottom of the support column 12. The piezoelectric buzzer is fixed to the base 11 or the support column 12 and electrically connected to a storage battery. The piezoelectric buzzer can operate at 3.2V and with a current not exceeding 12mA. The piezoelectric buzzer can have a frequency-converting ultrasonic mode and a predator simulation sound mode. The frequency band of the frequency-converting ultrasonic mode is 18kHz-28kHz, and a random frequency sweep method can be used; the frequency band of the predator simulation sound mode is 2kHz-5kHz.

[0081] The acoustic-optical synergy component can be linked with the low-light supplementary lighting component 50. When the ambient light detector triggers the supplementary light source 51 to operate, the microcontroller synchronously activates the piezoelectric buzzer. The piezoelectric buzzer can operate in a pulse intermittent mode, such as a 2-second sound cycle followed by an 8-second silence, or it can adopt a random frequency or random intermittent mode as needed. By linking the triggering strategy of the piezoelectric buzzer with the activation state of the supplementary light source 51, a synergistic effect of light and sound stimulation can be achieved in low-light environments, reducing the likelihood of birds adapting to a single stimulus pattern.

[0082] Example 3 This embodiment provides a hemispherical mirror-reflective bird deterrent device, which differs from Embodiment 1 in that: The curved reflector 31 does not employ a movable connection structure; instead, it is fixed to the inner side of the hemispherical reflector 20 at a preset tilt angle using screws, clips, or adhesive. This fixed structure is suitable for scenarios requiring simplified manufacturing and cost reduction. Even though the curved reflector 31 is a fixed structure, it can still form multi-path reflected light paths through its circumferential distribution and its cooperation with the hemispherical reflector 20.

[0083] In this embodiment, the low-illuminance supplementary lighting component 50 may omit the ambient light detection component and instead use timed control, manual control, or light control switch to control the operation of the supplementary light source 51; the supplementary light source 51 may also be a single LED lamp, LED light strip, flash lamp, or other low-power light-emitting element.

[0084] The functional component mounting part 60 can be located on the upper surface, side wall, or lower part of the support column 12 of the base 11; the cleaning component can be a set or multiple sets, and multiple sets of cleaning components can be arranged at intervals along the circumference of the base 11 to sweep different outer surface areas of the hemispherical reflector 20. The auxiliary bird deterrent component can be installed in combination with the cleaning component, or can be replaced according to site requirements.

[0085] Example 4 This embodiment provides a bird deterrent method, which is based on the hemispherical mirror reflective bird deterrent device of Embodiment 1, and includes the following steps: The incident light is directed to the hemispherical reflector 20 and the multiple arc-shaped reflectors 31, and a multi-path reflected light path is formed through the cooperation of the hemispherical reflector 20 and the multiple arc-shaped reflectors 31. The hemispherical reflector 20 swings relative to the support column 12 under the action of wind, causing the multi-path reflected light path to be dynamically swept with the swing of the hemispherical reflector 20. During the swinging process of the hemispherical reflector 20, the limiting pin 42 slides relative to the arc-shaped limiting track 41, and when the hemispherical reflector 20 swings to the preset maximum swing angle, the limiting pin 42 and the arc-shaped limiting track 41 abut against each other to restrict the hemispherical reflector 20 from continuing to swing. By using dynamically swept multipath reflected light paths to create visual stimulation for birds, bird deterrence can be achieved.
