Description
Technical Field
[0001] This invention relates to a windmill-type composite bird-proof device for power transmission lines, belonging to the technical field of auxiliary devices for power transmission lines. Background Technology
[0002] Birds pose multiple threats to power transmission lines. When they nest on transmission towers, the straw, twigs, and other materials they use are easily dampened by wind and rain and can be scattered onto the insulators, potentially causing short circuits and leading to line discharge and tripping faults. Furthermore, bird droppings on the towers are also a significant concern. Bird droppings on insulators reduce the creepage distance, increasing the risk of discharge between live conductors and tower components, which can also cause line grounding faults and tripping. More seriously, the salt in bird droppings can attract moisture, further reducing the insulator's resistance and inducing arcing faults. Arcing can erode the insulators, creating holes and severely impacting the operational performance and lifespan of the transmission lines.
[0003] Traditional wind-powered bird deterrents rely on natural wind to drive their rotation, which then scare away birds through reflected light or the sound generated by the rotation. However, in the absence of wind or insufficient wind, the device cannot rotate on its own, thus losing its bird-repelling effect. Furthermore, its effectiveness is affected by various factors, such as wind strength, wind direction, and the device's installation location and orientation. Changes in these factors can lead to fluctuations and instability in the device's bird-repelling effect. For example, when the wind is weak or the wind direction is inconsistent with the device's installation orientation, the device's bird-repelling effect may be significantly reduced. While ultrasonic bird deterrents may achieve significant results in the short term, their potential long-term harm to birds cannot be ignored. Prolonged and continuous ultrasonic waves may negatively impact a bird's nervous and physiological systems, interfering with its normal behavioral patterns and physiological functions, and in extreme cases, even causing death.
[0004] Patent CN114532325A discloses a composite overhead line bird repeller. This bird repeller integrates a bird repeller, a windmill bucket, and a sound-generating device. It combines a bird repeller with a windmill reflective device, a technology already in use, and incorporates fiber rods to promote the contact between the bird repeller and the air, accelerating its evaporation. It also includes a sound-generating device that uses changes in wind speed to emit sounds of different frequencies and volumes, preventing birds from becoming accustomed to the same sound and thus diminishing its deterrent effect. It uses chemical bird repellers to ensure the device is effective even in windless conditions. The capillary action of the fiber rods enhances the evaporation effect. The use of a mechanical structure reduces the cost of the device and improves its reliability. The use of varied bell sounds prevents birds from developing adaptation and enhances the bird repeller effect.
[0005] However, the dynamic effect of using reflection to repel birds in this bird repeller is not obvious enough, and the windmill bucket is difficult to rotate in a light breeze, thus reducing its effectiveness. Although the irregular sound emitted by the sound-generating device can prevent birds from adapting, in some cases, the irregular sound can cause instability in the bird-repelling effect, as birds may perceive these sounds as insignificant background noise. In this bird repeller, the bird repellent evaporates through the capillary action of the fiber rods exposed to the air. Because the fiber rods have capillary action, they can absorb and transport liquids. In humid environments such as rainy days, rainwater is absorbed through the capillary action of the fiber rods and enters the repellent cartridge. Rainwater entering the cartridge not only reduces the concentration of the bird repellent but also causes it to deteriorate or become ineffective, affecting its bird-repelling effect. The bird repellent in this bird repeller is constantly evaporating, which accelerates the frequency of repellent replacement, increasing maintenance costs. Furthermore, the instructions for replacing the bird repellent do not mention how to do so. Once the bird repellent has completely evaporated, the bird-repelling effect of this bird repeller will be greatly reduced. Summary of the Invention
[0006] To achieve the above objectives, this invention proposes a windmill-type composite bird-proof device for power transmission lines. This bird-proof device is a multi-mechanism composite device that is suitable for various weather conditions, improves the bird-proof effect of power transmission lines, and minimizes harm to birds.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0008] A windmill-style composite bird deterrent device for power transmission lines includes a U-shaped base, which is rotatably connected to a vertical rod bearing that can rotate around its own axis. The middle part of the vertical rod is rotatably connected to an outer sleeve, and a reflective component is rotatably connected to the middle part of the outer sleeve. A box-shaped structure is connected to the top of the outer sleeve, and the box-shaped structure is rotatably connected to a rotating rod. One end of the rotating rod is equipped with a rotation drive device, and the other end is connected to a sound-generating device. The rotation drive device drives the rotating rod to rotate, and the rotating rod drives the vertical rod to rotate through a transmission device. Inside the box-shaped structure are a container for holding bird repellent and a loading box, both of which are connected to a cover. A tail fin is connected to the outside of the box-shaped structure, and bird-repellent barbs are connected to the top of the loading box, with the barbs distributed radially.
[0009] This bird deterrent device integrates multiple functions to enhance its effectiveness. The rotating drive mechanism consists of rotating blades connected to a central ring. The blades are coated with reflective paint to enhance the bird deterrent effect. One end of the rotating rod connects to the rotating drive mechanism, and the other end connects to a wind whistle. Airflow resonance amplifies the sound, further deterring birds. The vertical rod and rotating rod are connected by gears. The rotation of the vertical rod drives the gears inside the outer sleeve, which in turn drives the bushing and fan blades to rotate. The reflective glitter on the fan blades provides multi-angle, dynamic reflection, enhancing visual warning. The box-shaped structure includes a bird repellent container and a loading box, which are controlled by a controller to automatically release the bird repellent according to the environment. The box-shaped structure is also equipped with barbs and a tail fin to ensure the device adjusts with the wind direction, maintaining optimal bird deterrence. The specially designed ring is engraved with spiral lines, mimicking threatening patterns such as the eyes of birds of prey. Its dynamic effect during rotation is significant, misleading birds into thinking it is a predator's gaze, thus prompting them to actively avoid the device. The overall design integrates visual, auditory, and olfactory bird deterrence methods, making it suitable for various environments and occasions, and improving bird deterrence effectiveness.
[0010] As a further technical solution, a drive gear is fitted around the middle of the vertical rod, and multiple through holes are opened on the outer sleeve along the circumference of the outer sleeve. A driven gear is fixed in each through hole, and the driven gear meshes with the drive gear. The reflective component includes a bushing and several fan blades. The inner ring of the bushing is provided with protruding gear teeth, which mesh with the driven gear.
[0011] As a further technical solution, a slide rail is provided on the outer ring of the outer sleeve, and a groove is provided on the inner side of the bushing, with the slide rail cooperating with the groove.
[0012] As a further technical solution, the fan blade has several connecting holes, and a rotating shaft is set in the connecting holes. The rotating shaft is connected to a reflective sheet. The reflective sheet is driven to rotate continuously by the rotating shaft under the action of wind. Due to the bending of the fan blade at a certain angle, combined with the continuous rotation of the fan blade itself, it can reflect light widely and dynamically, thereby greatly increasing the reflective range and reflective effect.
[0013] As a further technical solution, the rotary drive device consists of several rotating blades connected to a central ring, which is then connected to a rotating rod. The rotating blades are streamlined and coated with reflective paint on both sides.
[0014] As a further technical solution, the ring is engraved with a spiral line. When the ring rotates, the spiral line rotates rapidly with the ring, forming a visual dynamic pattern. This pattern may resemble the eye of a bird of prey or other patterns that make birds feel threatened under certain angles and lighting conditions, thereby improving the bird deterrent effect.
[0015] As a further technical solution, the sound-generating device consists of several whistles that rotate together with a rotating rod. Each whistle includes a spring coil, an electromagnet, a pneumatic control plate, a small ball, and a mouthpiece. The whistle has an air inlet, and the small ball is placed inside. The size of the air inlet channel is controlled by the pneumatic control plate, the electromagnet, and the spring coil. One end of the pneumatic control plate is hinged to the whistle body, and the other end is connected to the whistle body via the spring coil. An electromagnet is placed inside the whistle body, and the pneumatic control plate is magnetic. When airflow enters the whistle, it triggers resonance, making the whistle sound louder and clearer. The pneumatic control plate in the whistle is regulated by a controller to ensure a stable sound frequency, thereby achieving a bird-repelling effect.
[0016] As a further technical solution, the cover plate control device includes a traction electromagnet, a spring, and a slide rail; the cover plate is made of a magnetic material, one end of the spring is connected to the box-shaped structure, the other end is connected to the cover plate, the cover plate is connected to the slide rail, and a traction electromagnet is provided at the end of the slide rail away from the spring; the magnetism of the traction electromagnet is controlled by a controller.
[0017] As a further technical solution, a photosensitive sensor and a humidity sensor are installed on the top of the box-shaped structure; a speed sensor is also installed on the rotating rod; a solenoid valve is installed at the connection between the barb and the loading box; the photosensitive sensor, humidity sensor, solenoid valve, and speed sensor are all connected to the controller; a power supply is also installed on the box-shaped structure to power the controller. The barb is a hollow cylindrical tube, with the loading box for bird repellent connected to the bottom of the barb. The tip of the barb is needle-shaped, with the opening of the needle tip facing horizontally or downwards; a solenoid valve is installed at the connection between the barb and the loading box for bird repellent to control the release of the bird repellent. The barb also prevents birds from landing on this bird-proof device and also prevents birds from nesting on it. The controller operates by sensing the speed sensor on the rotating part and the photosensitive sensor and humidity sensor on the box-shaped structure. The tail end of the box-shaped structure is connected to a tail fin, which keeps the rotating part facing the wind, so the device can work continuously in windy conditions. A battery is installed inside the box-shaped structure to power the controller. By utilizing speed sensors, photosensors, humidity sensors, and a controller, intelligent monitoring and adjustment of the device's operating status are achieved. Under adverse conditions such as windless or rainy days, the device automatically releases bird repellent through the action of electromagnets and springs, enhancing its environmental adaptability and bird-repelling effect.
[0018] The beneficial effects of this invention are as follows:
[0019] The device combines visual, auditory, and olfactory bird deterrence methods to create a comprehensive and multi-layered bird-repelling effect. Visually, reflective discs on the rotating blades and fan blades reflect light from multiple angles and continuously change under wind force. These reflective discs can also rotate in light winds, greatly increasing the range and effectiveness of the reflection. This dynamic reflective effect provides a strong visual stimulus to birds, making them uneasy and prompting them to actively move away from the area. Auditorily, the resonant sound of the wind whistle produces a loud and clear sound with a stable frequency, creating an auditory deterrent to birds. Olfactorily, under unfavorable conditions such as windless or cloudy days, the controller opens the solenoid valve and cover, automatically releasing the bird repellent, enhancing the device's environmental adaptability and bird-repelling effect, avoiding unnecessary waste, and extending the lifespan of the bird repellent. Under unfavorable conditions such as rain, the controller closes the solenoid valve and cover to prevent the bird repellent from becoming damp in the container and loading box, thus ensuring the bird-repelling effect.

[0033] 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.
[0034] like Figure 1As shown, this embodiment discloses a windmill-type composite bird deterrent device for power transmission lines, including a U-shaped base 1. The lower side wall of the U-shaped base 1 has mounting holes. The U-shaped base 1 is rotatably connected to a vertical rod 18 that can rotate around its own axis via bearings. The middle part of the vertical rod 18 is connected to an outer sleeve 2 via a drive gear 24. The outer sleeve 2 is rotatably connected to the U-shaped base 1 via bearings. A rotating rod 13 is connected to the top of the vertical rod 18. The outer sleeve 2 can rotate around its own axis. A rotating reflective component is connected to the middle part of the outer sleeve 2. A box-shaped structure 9 is connected to the top of the outer sleeve 2. The box-shaped structure 9 is connected to the rotating component. A photosensitive sensor 903 and a humidity sensor 904 are installed above the box-shaped structure. Inside the box-shaped structure 9 are a container 907 for holding bird repellent and a loading box 908. A cover plate 16 control device is provided on the outside of the container 907. A controller is located inside the box-shaped structure 9. A tail fin 11 is connected to the tail end of the box-shaped structure 9. Bird-repellent barbs 8 are connected to the top of the box-shaped structure 9, and the barbs 8 are radially distributed. This bird deterrent device integrates multiple functions to enhance its effectiveness. The rotating drive mechanism consists of rotating blades 6 connected to a central ring 7. The blades are coated with reflective paint to enhance the bird deterrent effect. One end of the rotating rod 13 is connected to the rotating drive mechanism, and the other end is connected to a whistle 12. The whistle amplifies the sound through airflow resonance, further deterring birds. The vertical rod 18 meshes with the rotating rod 13 via gears. The rotation of the vertical rod 18 drives the gear inside the outer sleeve 2, which in turn drives the bushing 3 and fan blades 4 to rotate. The reflective glitter 501 on the fan blades 4 provides multi-angle, dynamic reflection, enhancing visual warning. The box-shaped structure 9 is equipped with a bird repellent container 907 and a loading box 908, which, under the control of a controller, automatically releases the bird repellent according to the environment. The box-shaped structure 9 is also equipped with barbs 8 and a tail fin 11 to ensure the device adjusts with the wind direction and maintains optimal bird deterrence. The specially designed ring 7 is engraved with spiral lines 25, mimicking threatening patterns such as the eyes of birds of prey. Its dynamic effect during rotation is significant, misleading birds into thinking they are being watched by predators, thus prompting them to actively avoid the device. The overall design integrates visual, auditory, and olfactory bird deterrence methods, is suitable for various weather conditions, and improves the bird deterrence effect of power transmission lines.
[0035] Furthermore, the rotating component includes a speed sensor 901, a rotating rod 13, a rotation drive device, and a sound-generating device. One end of the rotating rod 13 is connected to the rotation drive device, which drives the entire rod to rotate. The rotation drive device consists of several rotating blades 6 connected to a central ring 7, which in turn connects to the rotating rod 13. The rotating blades 6 are streamlined and coated with reflective paint on both sides. When the rotating blades 6 rotate, they reflect light to the surrounding area, thereby enhancing the bird-repelling effect. The other end of the rotating rod 13 is connected to the sound-generating device, which consists of several whistles 12 that rotate with the rotating rod 13. When the wind blows the whistles 12 or the whistles 12 rotate themselves, the airflow is effectively guided into the whistle opening. At this entrance, the airflow is compressed and accelerated, transforming into a high-speed and unstable airflow.
[0036] Furthermore, the whistle 12 includes a spring coil 1201, an electromagnet 1202, an air control plate 1203, a small ball 1204, and a whistle nozzle 1205; the whistle 12 is a sphere in its entirety, with the whistle nozzle 1205 on it, and the small ball 1204 inside the whistle 12; the size of the air inlet channel is controlled by the air control plate 1203, the electromagnet 1202, and the spring coil 1201. One end of the air control plate 1203 is hinged to the body of the whistle 12, and the other end is connected to the body of the whistle 12 through the spring coil 1201. The electromagnet 1202 is installed inside the body of the whistle 12, and the air control plate 1203 is magnetic.
[0037] Within the whistle 12, high-speed airflow continues to flow and encounters obstacles, such as the special structure of the small ball 1204 or the whistle tip 1205. These obstacles disturb the airflow, leading to the formation of vortices and turbulence. These vortices and turbulence cause rapid changes in airflow pressure both spatially and temporally. Due to these pressure changes, the small ball 1204 begins to vibrate under the influence of the airflow. Simultaneously, the airflow can also directly rub against the edge of the whistle tip 1205, causing the tip itself to vibrate. Both vibration modes enable the whistle 12 to produce sound. This vibration further induces air vibration within the sound-producing cavity, thus forming sound waves. These sound waves continuously reflect and superimpose within the sound-producing cavity, creating a resonance effect. This resonance effect not only enhances the amplitude of the sound waves but also makes the sound clearer and louder. Finally, the resonated and amplified sound waves propagate into the outside air through the opening of the whistle 12. During the compression and acceleration process of the airflow entering the inlet, it is regulated by the controller. When the speed sensor 901 detects that the rotation speed of the rotating rod 13 is relatively fast, the airflow entering the whistle 12 is large. The controller receives the signal transmitted by the speed sensor 901 and controls the current supplied to the electromagnet 1202 to increase its magnetism. The air control plate 1203 itself is made of a magnetic material. One end of the air control plate 1203 is hinged to the whistle 12, and the end near the electromagnet is connected to the whistle 12 through the spring coil 1201.
[0038] Furthermore, the air control plate 1203 moves closer to the electromagnet 1202 due to the enhanced magnetic effect of the electromagnet 1202, thus widening the airflow channel after entering the whistle 12 and slowing down the airflow speed. This keeps the sound emitted by the whistle 12 within a certain frequency range. When the rotation speed of the rotating rod 13 is slower, the airflow entering the whistle 12 is smaller. The controller reduces the current to the electromagnet 1202, decreasing its magnetism. Due to the elastic force of the spring coil 1201, the air control plate 1203 moves away from the electromagnet 1202, narrowing the airflow channel after entering the whistle 12 and increasing the airflow speed. This ensures that the frequency of the sound emitted by the whistle 12 is basically consistent with the frequency emitted when the rotating rod 13 rotates faster, maintaining sound stability. Because birds are more sensitive to high-frequency sounds, modifications can be made to the air inlet and mouthpiece 1205 of the whistle 12 in practical applications to ensure that the emitted sound effectively repels birds.
[0039] The vertical rod 18 and the rotating rod 13 are connected by a transmission gear 19. When the rotating rod 13 rotates, the vertical rod 18 also rotates around its own axis under the drive of the transmission gear 19. A drive gear 24 is connected in the middle of the vertical rod 18. The drive gear 24 rotates together with the vertical rod 18. There is an outer sleeve 2 that surrounds the entire vertical rod 18. Several through holes are opened in the middle of the outer sleeve 2. A rotatable driven gear 22 that meshes with the drive gear 24 is installed in the through holes. The outer surface of the outer sleeve 2 is also provided with a raised slide rail 23.
[0040] like Figure 9 As shown, the rotating reflective component includes a bushing 3 and several fan blades 4. The bushing 3 is connected to the slide rail 23 protruding on the outer surface of the outer sleeve 2 through its inner groove 21. At the same time, there are protruding gear teeth 20 on the inner side of the bushing 3 that mesh with the driven gear 22 in the through hole of the outer sleeve 2. Several fan blades 4 are also connected to the bushing 3. The fan blades 4 form a certain angle with the horizontal plane. Several connecting holes 5 are opened on the fan blades 4. A rotating shaft 502 is set in the connecting hole 5. The rotating shaft 502 is connected to the reflective bright sheet 501.
[0041] In windy conditions, the wind drives the rotating blade 6 to rotate, which in turn causes the rotating rod 13 to rotate as well. Since there is a transmission gear 19 meshing between the rotating rod 13 and the vertical rod 18, the vertical rod 18 will drive the driving gear 24 in its middle to rotate. The driving gear 24 in the middle of the vertical rod 18 will drive the driven gear 22 in the through hole of the outer sleeve 2 to rotate. Because the inner side of the bushing 3 has protruding gear teeth 20 that mesh with the driven gear 22 in the through hole of the outer sleeve 2, and the bushing 3 and the outer sleeve 2 are connected by a groove 21 and a protruding slide rail 23, when the driven gear 22 in the through hole of the outer sleeve 2 rotates, the bushing 3 will drive the fan blade 4 on its outer side to rotate around the outer sleeve 2. The reflective glitter 501 in the connecting hole 5 of the fan blade 4 will be driven to rotate continuously by the rotating shaft 502 under the action of the wind. Since the fan blade 4 has a certain angle of curvature, combined with the continuous rotation of the fan blade 4 itself, it can reflect light widely and dynamically, thereby greatly increasing the reflective range and reflective effect. Driven by the wind, the reflective sequins 501 continuously change position and angle as the fan blades 4 rotate, producing a flashing and reflecting light effect. This constantly changing and dynamic visual stimulation serves as a strong warning signal to birds. The fan blades 4 are designed with a certain angle of curvature, which not only enhances the rotational efficiency driven by the wind but also allows the reflective sequins 501 to reflect light from different angles and heights during rotation. This multi-angle reflection expands the bird deterrent range, ensuring an effective deterrent effect on birds over a wider area.
[0042] Furthermore, the box-shaped structure 9 has a container 907 and a loading box 908 for holding bird repellent on both sides and the top. The container 907 and the loading box 908 are provided with a cover 10 on the upper side, which can be used to replenish or replace the bird repellent in a timely manner. The box-shaped structure 9 is connected to the rotating structure through a bearing 902. A photosensitive sensor 903, a humidity sensor 904, and a protruding cylinder are provided on the top of the box-shaped structure 9. Bird-proof barbs 8 are installed on the cylinder, which are arranged radially outward. The barbs 8 are hollow cylindrical tubes. The loading box 908 for holding bird repellent is connected to the bottom of the barbs 8. The tip of the barb 8 is needle-shaped, and the opening of the needle tip is horizontal or downward to prevent dust or rainwater from clogging it.
[0043] Furthermore, a solenoid valve 905 is installed below the barb 8 and at the connection point with the bird repellent loading box 908. When the humidity sensor 904 detects excessive humidity in the external environment, such as on rainy days, the humidity sensor 904 sends a signal to the controller to close the solenoid valve 905, preventing the bird repellent from becoming less effective after it gets wet. At the same time, the operation of the solenoid valve 905 is regulated by the speed sensor 901 and the photosensor 903. When there is no wind or it is cloudy, the controller receives the signal from the sensors and opens the solenoid valve 905, allowing the bird repellent odor to be released through the tip of the barb 8 for bird repellency.
[0044] When there is wind or the weather is clear, the controller receives a signal from the sensor and closes the solenoid valve 905, ending the release of the bird repellent. The barbs 8 also prevent birds from landing on the bird deterrent device and from nesting there. The box-shaped structure 9 is fixedly connected to the outer tube 2, and the tail fins 11 are connected to the upper and lower ends of the box-shaped structure 9. When the wind direction changes, the tail fins 11 are first affected by the wind and drive the entire box-shaped structure 9 and outer tube 2 to rotate, thus accurately and quickly indicating the direction of the wind. The box-shaped structure 9 is connected to the internal rotating rod 13 by a bearing 902, the rotating rod 13 is engaged with the vertical rod 18 by a transmission gear 19, and the vertical rod 18 is engaged with the outer tube 2 by a gear. The vertical rod 18, outer tube 2, and U-shaped base 1 are all rotatably connected via bearings. Therefore, when the box-shaped structure 9 and outer tube 2 rotate, the internal rotating rod 13 and vertical rod 18 also rotate together, ensuring that the rotating parts always face the windward direction. Thus, this device can operate continuously in windy conditions. The box-shaped structure contains a battery 906 to power the controller. In windy conditions, rotating the blades 6 can charge the battery.
[0045] Furthermore, such as Figure 3 As shown, the control device for the cover 16 outside the bird repellent container 907 includes a traction electromagnet 17, a spring 14, a slide rail 15, and a cover 16. The cover 16 is made of a magnetic material. The spring 14 is connected to the raised vertical panel of the box-shaped structure 9. Several springs 14 are connected at one end to the vertical panel and at the other end to the cover 16. The cover 16 is connected to the slide rail 15 and can move within the range of the slide rail 15. The sliding part of the slide rail 15 has an L-shaped vertical surface. One end of the slide rail 15 is connected to the cover 16, and the other end is connected to the traction electromagnet 17. The traction electromagnet 17 is fixedly connected to the slide rail 15. The slide rail 15 can cover the upper and lower ends of the cover 16 and the traction electromagnet 17, and the slide rail 15 extends a certain distance beyond the traction electromagnet 17 and the cover 16. The two ends of the slide rail 15 are rectangular to ensure the position of the cover 16 and the traction electromagnet 17.
[0046] The controller operates by sensing the rotation speed sensor 901 on the rotating component and the photosensitive sensor 903 on the box-shaped structure 9. In windy or sunny conditions, the cover 16 is closed, and the spring 14 is in its natural state. In windless or cloudy conditions, the controller energizes the traction electromagnet 17 via signals from the rotation speed sensor 901 or the photosensitive sensor 903, causing the traction electromagnet 17 to magnetically attract the cover 16. The cover 16 moves along the slide rail 15 towards the traction electromagnet 17, stretching the spring 14. The upper part of the outer shell of the box-shaped structure 9, which contains bird repellent containers 907 on both sides and is covered by the cover 16, has several release holes. The bird repellent in the containers 907 evaporates through these release holes. By releasing a specific, repulsive odor, the bird repellent utilizes the birds' keen sense of smell and instinctive reaction to threats to stimulate their nervous or respiratory systems, causing discomfort and prompting them to fly away from the area, thus achieving a repelling effect. In windy or sunny conditions, the controller receives signals from the speed sensor 901 or the photosensor 903, causing the traction electromagnet 17 to lose power and its magnetism to be deactivated. The cover 16, under the action of the spring 14, returns to its initial position, covering the release hole on the container 907, thus ending the evaporation of the bird repellent. When the humidity sensor 904 detects excessive ambient humidity, such as during rain, it sends a signal to the controller, de-energizing the traction electromagnet 17 and closing the cover 16 to prevent the bird repellent from becoming damp and reducing its effectiveness.
[0047] Furthermore, such as Figure 10 As shown, the aforementioned ring 7 is engraved with a spiral line 25. When the wind blows and the rotating blade 6 rotates, the spiral line 25 on the ring 7 also rotates. The main function of the spiral line 25 is that its dynamic effect during rotation mimics the eyes of a raptor or other patterns that would make birds feel threatened. When the spiral line 25 rotates rapidly with the ring 7, its dynamic changes will mislead birds into thinking that they are being watched by a raptor or other predator, thus causing them to choose to avoid the area, thereby achieving the purpose of bird deterrence.
[0048] The aforementioned device combines visual, auditory, and olfactory bird deterrence methods to create a comprehensive and multi-layered bird-repelling effect. Visually, reflective paint and dynamically changing reflective flakes on the fan blades generate a strong visual warning. Auditorily, the resonant sound of the wind whistle produces a loud and clear sound with a stable frequency, effectively deterring birds. Olfactorily, bird repellent is released under specific conditions, utilizing birds' aversion to specific odors. The rotating blades and reflective flakes reflect light from multiple angles and continuously change under wind force, greatly increasing the range and effectiveness of the reflection. This dynamic reflective effect creates a strong visual stimulus for birds, making them uneasy and prompting them to actively move away from the area. The device operates continuously in windy conditions through gear meshing and bearing connections. The tail fin design allows the device to accurately and quickly respond to changes in wind direction, keeping the rotating parts always facing the windward direction to maximize the bird-repelling effect. Intelligent monitoring and adjustment of the device's operating status are achieved using speed sensors, photosensors, humidity sensors, and a controller. Under unfavorable conditions such as windless or cloudy days, the controller opens the solenoid valve and cover, automatically releasing the bird repellent, enhancing the device's environmental adaptability and bird-repelling effect. Conversely, under unfavorable conditions such as rainy days, the controller closes the solenoid valve and cover to prevent the bird repellent from becoming damp inside the container and loading box, thus ensuring the bird-repelling effect. The device's design and use fully consider environmental protection and energy conservation requirements. For example, the release of the bird repellent occurs under specific conditions, avoiding unnecessary waste and environmental pollution. The device's structural design is flexible and adaptable to various environments and occasions. Whether in farmland, orchards, airports, power facilities, or other locations requiring bird control, the device's configuration and parameters can be adjusted and optimized to meet specific needs.
