Description

Technical Field

[0001] This utility model relates to the field of bird deterrence technology, specifically to a multifunctional solar-powered bird deterrence device. Background Technology

[0002] Bird deterrent lights are devices that deter birds by emitting intermittent bright light or flashing beams of light at specific frequencies. They work by utilizing birds' instinctive alertness to sudden, intense light, simulating predator signals or danger signals, thus prompting birds to actively avoid protected areas. In agriculture, these devices are widely used in orchards, rice paddies, fishponds, and grain-growing areas. Their main function is to effectively reduce bird damage to ripe fruit, seedlings, and aquatic products, significantly reducing agricultural losses while avoiding the use of chemical agents or physical methods of trapping birds, thus being both environmentally friendly and sustainable.

[0003] Bird deterrent devices are typically fixed in locations with open views, such as field ridges, fences, utility poles, or high points in the center of crop areas, to maximize coverage. However, fixed installations have significant drawbacks: their static nature results in limited protection, creating blind spots that allow birds to enter from other directions; the long-term, monotonous flashing pattern can lead to bird adaptation, reducing the deterrent effect over time; and they cannot dynamically respond to bird activity patterns or intrusion directions, lacking flexibility when dealing with highly mobile and unpredictable flocks of birds. Therefore, there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional solar-powered bird deterrent device to solve the technical problem that existing bird deterrent warning lights are usually fixed in place, which makes birds adapt easily and reduces their bird deterrent effect over time.

[0005] To achieve this objective, the present invention adopts the following technical solution: A multifunctional solar-powered bird deterrent device includes a laser module, a sound wave module, a solar panel, a housing, a rotating assembly, and a support frame. The laser module emits a laser beam of a specific wavelength to deter birds, and the sound wave module emits deterrent sound waves. Both the laser module and the sound wave module are housed within the housing. The solar panel is located on the top of the housing and converts solar energy into electrical energy to power the various electrical modules. The support frame is fixed to an external support, and the housing is rotatably mounted on the support frame via the rotating assembly.

[0006] Optionally, the rotating assembly includes a mounting plate, a connector, and an adjusting member. The mounting plate, the connector, and the adjusting member are all rigidly disposed. The mounting plate is fixed to the housing. The connector passes through the mounting plate and the end of the bracket along a first direction. The end of the bracket is elastically disposed. The adjusting member is disposed at the end of the connector and can move in a direction close to or away from the mounting plate to abut and fix the bracket to the mounting plate.

[0007] Optionally, the projected area of ​​the solar panel on the horizontal plane is greater than the projected area of ​​the housing on the horizontal plane.

[0008] Optionally, a mounting base is provided inside the housing, and the laser module includes a laser emitting unit and a warning light unit. The laser emitting units are evenly disposed on the side wall of the mounting base, and the warning light units are evenly disposed on the top surface of the mounting base.

[0009] Optionally, a reflector is also provided inside the housing, the reflector being disposed between the mounting base and the solar panel, the outer peripheral surface of the reflector being an arc-shaped surface, the reflector being used to reflect the light from the warning light unit to the outside of the housing.

[0010] Optionally, the bird deterrent device further includes a photosensitive sensing unit, which is communicatively connected to the control module. The control module automatically controls the start and stop of the sound wave module based on the ambient light intensity detected by the photosensitive sensing unit. The sound wave module is activated when the light intensity is higher than a set threshold, and deactivated when the light intensity is lower than the set threshold.

[0011] Optionally, the end faces of the mounting plate and the bracket that are close to each other are configured as an interlocking structure.

[0012] Optionally, a sealing ring is provided between the housing and the solar panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the design of a rotating component, allows the housing to flip on the support, enabling the built-in laser and acoustic modules to dynamically adjust their deterrent direction. This expands the effective protective coverage of a single device, freeing the laser beam and acoustic waves from being confined to a fixed area. Their range extends from a local point to a nearly 360-degree omnidirectional area, achieving comprehensive protection over a large area with fewer devices. Secondly, it effectively breaks down birds' adaptability and enhances the persistence of the bird-repelling effect. By constantly changing the spatial position of the light and sound sources, the visual and auditory stimuli generated by the bird-repelling device are random and unpredictable for birds, simulating the constant patrolling of predators within the area and preventing birds from developing immunity. Furthermore, the solar panel installed on top of the housing adjusts its orientation in real time as the housing rotates, allowing it to face the sun for a longer period throughout the day, maximizing the absorption of solar radiation and thus charging the battery with more power. This ensures that the device has sufficient energy reserves to maintain normal operation even in cloudy or rainy weather. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Figure 1 A schematic diagram of the overall structure of the solar-powered bird deterrent device provided in this embodiment of the utility model; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 A cross-sectional view of the solar-powered bird deterrent device provided in this embodiment of the utility model; Figure 4 for Figure 3 Enlarged view of point B in the middle; Figure 5 for Figure 3 Enlarged view of point C in the middle.

[0022] The solar-powered bird deterrent device provided in this embodiment can be applied to various outdoor scenarios where birds need to be avoided, such as orchards, farmlands, airports, wind farms, and aquaculture areas. This embodiment improves the structure of the solar-powered bird deterrent device to prevent birds from developing adaptation and enhance the bird deterrent effect.

[0023] Please see Figures 1-5The solar-powered bird deterrent device provided in this embodiment includes a laser module 10, a sound wave module 20, a solar panel 30, a housing 40, a rotating assembly 50, and a support 60. The laser module 10 is used to emit a laser beam of a specific wavelength to deter birds, and the sound wave module 20 is used to emit deterrent sound waves. Both the laser module 10 and the sound wave module 20 are disposed inside the housing 40. The solar panel 30 is disposed on the top of the housing 40 and is used to convert solar energy into electrical energy to power each power-consuming module. The support 60 is fixed to an external support, and the housing 40 is rotatably mounted on the support 60 via the rotating assembly 50.

[0024] Specifically, the housing 40, as the external protective component of the device, can be made of transparent polycarbonate, acrylic, or other high-strength light-transmitting materials. These materials not only have good light transmittance but also excellent weather resistance and impact resistance. The laser module 10 is used to emit a laser beam of a specific wavelength and can be a semiconductor laser or a solid-state laser. Under the protection of the light-transmitting housing 40, these devices can effectively output the laser beam through the light-transmitting area of ​​the housing 40, creating a strong visual deterrent to birds. The sound wave module 20 is used to generate deterrent sound waves. A high-frequency speaker can be used to play sounds such as gunshots, firecrackers, raptor calls, bird cries, or ultrasound. The light-transmitting housing 40 has good sound transmission in the sound wave frequency band, ensuring that the sound is transmitted to the external environment without significant obstruction, thus achieving auditory interference to birds. All of the above modules are mature electronic components, and their related structures are well known to those skilled in the art; therefore, they will not be described in detail in this embodiment.

[0025] By using the rotating component 50, the housing 40 can be flipped on the bracket 60, allowing the built-in laser module 10 and sound wave module 20 to dynamically adjust their deterrent direction. This expands the effective protective coverage of a single device, and the laser beam and sound waves are no longer limited to a fixed area. Their range of action can be extended from a local point to a nearly 360-degree all-around area, thus achieving protection of a large area with fewer devices. Secondly, it effectively breaks the birds' adaptability and enhances the persistence of the bird-repelling effect. The bird-repelling device continuously changes the spatial position of the light and sound sources, and the resulting visual and auditory stimulation... For birds, the activity is random and unpredictable, simulating the constant patrolling of predators within the area to prevent birds from developing immunity. In addition, the solar panel 30 installed on top of the housing 40 adjusts its orientation in real time as the housing 40 rotates, allowing it to face the sun for a longer period throughout the day, maximizing the absorption of solar radiation and thus charging the battery with more power, ensuring that the device has sufficient energy reserves to maintain normal operation even in cloudy or rainy weather. The bracket 60, as a fixed component, can be made of metal or aluminum alloy profiles, possessing high strength and good weather resistance, and can be stably installed on the ground, buildings, or other supports.

[0026] Furthermore, the rotating assembly 50 includes a mounting plate 501, a connector 502, and an adjusting member 503. The mounting plate 501, connector 502, and adjusting member 503 are all rigidly mounted. The mounting plate 501 is fixed to the housing 40. The connector 502 extends through the mounting plate 501 and the end of the bracket 60 along a first direction. The end of the bracket 60 is elastically mounted. The adjusting member 503 is located at the end of the connector 502 and can move towards or away from the mounting plate 501 to securely abut against the bracket 60 and the mounting plate 501. Specifically, the mounting plate 501, as a fixing component between the rotating assembly 50 and the housing 40, can be made of sheet metal or high-strength alloy material. It is firmly connected to the outer surface of the light-transmitting housing 40 by fastening or welding, thereby providing a stable mounting reference for the rotating assembly 50. The connector 502 extends through the mounting plate 501 and the end of the bracket 60 along the first direction. Its form can be a cylindrical pin or bolt structure, as is well known to those skilled in the art, and can provide rotation or clamping functions while maintaining strength. The end of the bracket 60 adopts an elastic structure design, which can be used to clamp the connector 502 through elastic deformation. The material can be an elastic metal sheet to ensure a stable clamping effect during repeated operations.

[0027] An adjusting member 503 is located at the end of the connecting member 502. By moving it closer to or further away from the mounting plate 501, the distance between the end of the bracket 60 and the mounting plate 501 can be adjusted, thereby achieving a tight fixation between the bracket 60 and the mounting plate 501. In actual use, the installer only needs to rotate or move the adjusting member 503 to complete the fixing or unlocking operation of the housing 40. When the adjusting member 503 is released, the relative position between the connecting member 502 and the end of the bracket 60 allows the housing 40 to rotate, thereby changing the direction of action of the internal laser module 10 and the acoustic module 20. When the adjusting member 503 is locked, the end of the bracket 60 is tightly abutted against the mounting plate 501 by the elastic force generated by the elastic deformation, ensuring that the housing 40 is in a stable position and effectively resisting the displacement caused by external vibration, wind impact, and other factors.

[0028] For example, the adjusting member 503 can be a dial with a cam structure. The clamping and releasing between the bracket 60 and the mounting plate 501 is achieved by rotating the dial, which improves the convenience of the operator. In addition, the adjusting member 503 can also be a nut with a threaded structure. The adjusting member 503 and the connecting member 502 are threaded together to achieve the clamping and releasing between the bracket 60 and the mounting plate 501.

[0029] Furthermore, the projected area of ​​the solar panel 30 on the horizontal plane is larger than that of the housing 40 on the horizontal plane. Specifically, since the solar panel 30 is located on the top surface of the housing 40, and the projected area of ​​the solar panel 30 on the horizontal plane is larger than that of the housing 40 on the horizontal plane, the solar panel 30 forms an eave-like structure at the top of the device. This structure can provide shelter for the housing 40 below during rainy weather, effectively preventing rainwater from directly entering the internal cavity where the acoustic module 20 and other electrical components are located. This forms a natural protective barrier without adding any additional structures, avoiding the risk of water ingress into the acoustic module 20, laser module 10, and related components, and extending the service life of the entire device.

[0030] Furthermore, a mounting base 401 is provided inside the housing 40. The laser module 10 includes a laser emitting unit 101 and a warning light unit 102. The laser emitting units 101 are evenly arranged on the side wall of the mounting base 401, and the warning light units 102 are evenly arranged on the top surface of the mounting base 401. Specifically, the laser module 10 is mounted on the mounting base 401, including the laser emitting unit 101 and the warning light unit 102. The laser emitting unit 101 is evenly arranged on the side wall of the mounting base 401, while the warning light units 102 are evenly distributed on the top surface of the mounting base 401. The laser emitting unit 101 is a device capable of emitting a laser beam of specific wavelength and direction. It acts directly on the bird's visual system through a high-brightness beam, simulating the deterrent light source of predators in nature, thereby effectively driving away birds. Evenly arranging it on the side wall of the mounting base 401 can form a surrounding beam coverage, allowing the laser beam to be emitted from multiple angles, increasing the bird-repelling coverage, avoiding blind spots caused by a fixed direction, and improving the overall protection effect.

[0031] The warning light unit 102, as a device that generates a high-brightness flashing light source, can use an LED light source, which features low energy consumption, long lifespan, and high luminous intensity. By evenly distributing the warning light units 102 on the top surface of the mounting base 401, irregular flashing signals can be emitted outwards when the device is working, simulating sudden optical stimuli in the natural environment, further enhancing the deterrent effect on birds. The presence of the warning light not only repels birds with strong flashing light during the day, but also maintains an effective bird-repelling effect at night or in low-light environments, compensating for the limited range of laser beams at night, thus achieving all-weather bird-repelling protection.

[0032] The laser emitting unit 101 and the warning light unit 102 form a combined mechanism of visual deterrence and flashing interference. The two work together to continuously generate random optical stimuli in space and time, breaking the birds' adaptability and preventing them from developing immunity due to prolonged exposure to a fixed light source.

[0033] Furthermore, a reflector 402 is also provided inside the housing 40. The reflector 402 is positioned between the mounting base 401 and the solar panel 30. The outer peripheral surface of the reflector 402 is curved, and it is used to reflect the light from the warning light unit 102 to the outside of the housing 40. Specifically, the reflector 402 is located between the mounting base 401 and the solar panel 30, and its outer peripheral surface is processed into a continuous curved surface structure. The surface of the reflector 402 is usually coated with a metal film or a high-reflectivity coating to effectively reflect the light emitted by the light source. When the warning light unit 102 is working, some light may be emitted upwards or in non-target directions, which would result in energy waste if not guided. By setting up the reflector 402, these ineffective light rays can be reflected to the outside of the housing 40, allowing them to re-participate in the formation of bird-repelling optical stimuli, thus enhancing the utilization efficiency of the light source. At the same time, the curved reflective surface structure can reduce light loss caused by multiple reflections, ensuring that the reflected light still maintains a high brightness, thereby improving the deterrent effect of the optical stimulus on birds.

[0034] Furthermore, the solar-powered bird deterrent device also includes a photosensitive sensing unit, which is communicatively connected to the control module. The control module automatically controls the start and stop of the acoustic module 20 based on the ambient light intensity detected by the photosensitive sensing unit. The acoustic module 20 is activated when the light intensity is higher than a set threshold, and deactivated when the light intensity is lower than the set threshold. Specifically, the photosensitive sensing unit is a sensor capable of real-time detection of ambient light intensity. It typically uses a photodiode or photoresistor as its core detection component, converting light intensity into a corresponding electrical signal output. The control module can employ a microcontroller, electronic control chip, or programmable logic controller (PLC) structure. After receiving the signal from the photosensitive sensing unit, it analyzes and judges the data and automatically issues control commands based on preset thresholds, thereby managing the start and stop of the acoustic module 20.

[0035] In actual operation, when the photosensitive sensing unit detects that the light intensity is higher than a set threshold, the control module issues a control command to drive the acoustic module 20 to emit bird-repelling sound waves, simulating predator or disturbance sounds, effectively deterring flocks of birds that are frequently active during the day. When the photosensitive sensing unit detects that the light intensity is lower than the set threshold, the control module automatically shuts off the acoustic module 20, thus stopping the device from playing sound signals at night. In this way, the device achieves an automatic light-sensing mode, automatically playing bird-repelling sounds during the day and automatically shutting off the acoustic module 20 at night, avoiding noise interference to surrounding residents or special areas caused by continuous sound emission.

[0036] Furthermore, the end faces of the mounting plate 501 and the bracket 60 that are close to each other are configured with an interlocking structure. Specifically, the interlocking structure can be a toothed interlocking structure, a corrugated interlocking structure, or a convex-concave mating structure. Through the interlocking structure, the mounting plate 501 and the bracket 60 are less likely to slide relative to each other when they come into contact, increasing the friction between the mounting plate 501 and the bracket 60. Since the housing 40 of the bird deterrent device usually needs to be adjusted to different preset angles in actual use to adapt to different installation environments, such as in farmland, orchards, or the protection location of power transmission lines, the orientation and angle of the housing 40 directly affect the radiation range of sound waves or light waves. Therefore, the interlocking structure can effectively prevent the housing 40 from shifting due to wind, vibration, or other external forces after it is adjusted to a suitable angle, thereby maintaining the stability of the working direction of the device and ensuring the continuity of the bird deterrent effect.

[0037] Furthermore, a microwave radar sensor is also installed inside the housing 40. This sensor determines the presence and location of objects by emitting microwave signals and receiving reflected waves. It can accurately detect flocks of birds or large birds within a diameter of about 10 meters. It can analyze the size, speed and direction of the birds, thereby reducing the false alarm rate and ensuring reliable start-up of the device in complex environments.

[0038] In practice, when the microwave radar sensor detects a target entering the monitoring range, the control module triggers the simultaneous activation of the green laser module 10 and the sound and light module, forming a powerful deterrent mode. The visible light emitted by the green laser module 10 can create visual interference through rapid scanning and flashing bright spots, causing birds to feel fear and avoid the area, while the sound and light module enhances the deterrent effect by playing specific sound waves and flashing signals.

[0039] Furthermore, a sealing ring 403 is provided between the housing 40 and the solar panel 30. Specifically, the sealing ring 403 is disposed between the connecting end faces of the housing 40 and the solar panel 30. Its function is to form a tight sealing interface to prevent rainwater, dust or moisture from entering the interior of the housing 40, thereby providing effective protection for the internal module. The sealing ring 403 is a ring or strip-shaped sealing structure formed by using elastic material. It can fit against the two end faces during stress or assembly to achieve the barrier of media such as air and moisture. The above structure is a conventional sealing method in the art. In this embodiment, elastic materials such as rubber rings, silicone rings or fluororubber rings can be selected.

[0040] By providing a sealing ring 403 between the housing 40 and the solar panel 30, the elastic body of the sealing ring 403 can undergo slight deformation under assembly pressure, filling the tiny gaps between the two end faces, thereby achieving watertightness and dustproof effects. Furthermore, the sealing ring 403 can maintain a tight bond between the housing 40 and the solar panel 30 under external force or during thermal expansion and contraction, preventing loosening due to vibration or wind, thus further improving the reliability and durability of the device.

[0041] In summary, the solar-powered bird deterrent device provided in this embodiment avoids birds developing adaptations and improves the bird deterrent effect.

[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
