Description

Technical Field

[0001] The invention relates to a windmill type composite bird-proofing device for a power transmission line, belonging to the technical field of power transmission line auxiliary devices. Background Art

[0002] Birds pose multiple threats to power transmission lines. When they build nests on transmission towers, the straw, branches and other materials they use are easily damp in wind and rain and drift onto insulators, which can cause insulator short circuits, leading to line discharges and tripping faults. In addition, the defecation behavior of birds on towers cannot be ignored. Bird droppings falling on insulators will reduce their creepage distance, increase the risk of discharge between live conductors and tower components, and may also cause line grounding faults and tripping. What's more serious is that the salt in bird droppings can attract moisture, further reducing the resistance of insulators, inducing arc faults, and arcs burning insulators to form holes, seriously affecting the operating performance and life of transmission lines.

[0003] The working principle of traditional pneumatic bird-repellent devices is to rely on natural wind to drive their rotation, and then drive away birds by reflecting light or generating sound. However, in the absence of wind or insufficient wind, the device cannot rotate on its own, thus losing the bird-repelling effect. And its bird-repelling effect is affected by many factors, such as wind force, wind direction, installation location and direction of the device, etc. Changes in these factors may lead to fluctuations and instability in the bird-repelling effect of the device. For example, when the wind force is small or the wind direction is inconsistent with the installation direction of the device, the bird-repelling effect of the device may be greatly reduced. Although bird-repelling methods such as ultrasonic bird repellent may achieve significant results in the short term, in the long run, the potential harm that they may cause to birds cannot be ignored. The long-term continuous effect of ultrasound may have a negative impact on the nervous system and physiological system of birds, interfere with their normal behavior patterns and physiological functions, and may even cause the death of birds in extreme cases.

[0004] Patent CN114532325A discloses a composite overhead line bird repellent, which combines a drug, a windmill bucket, a sound-generating device, etc. The bird repellent is combined with a windmill reflective device in the prior art, and a fiber rod is added to promote the contact between the bird repellent and the air to accelerate volatilization. The sound-generating device also includes a sound-generating device that uses wind speed changes to emit sounds of different frequencies and sizes to prevent birds from getting used to the same sound and losing its deterrent effect. Chemical drugs are used to repel birds to prevent the device from losing its bird-repelling effect under windless conditions; the capillary action of the fiber rod is used to improve the volatilization effect; a mechanical structure is used to reduce the cost of the device and improve the reliability of the device; and variable ringtones are used to prevent birds from adapting and enhance the bird-repelling effect.

[0005] However, the dynamic effect of using reflection to drive birds in this bird repellent is not obvious enough, and in a breeze, the windmill bucket is difficult to rotate, thereby reducing the bird repellent effect. Although the irregular sound emitted by the sound-emitting device can prevent birds from adapting, in some cases, the irregular sound will cause the instability of the bird repellent effect, and birds may regard these sounds as insignificant background noise. In this bird repellent, the volatilization of the bird repellent is exposed to the air through the capillary action of the fiber rod. Since the fiber rod has a capillary action, it means that it can absorb and transmit liquids. In a humid environment such as rainy days, rainwater and the like are absorbed by the capillary action of the fiber rod and enter the inside of the medicine box. The entry of rainwater and the like into the medicine box will not only reduce the concentration of the bird repellent, but also cause the bird repellent to deteriorate or fail, affecting the bird repellent effect. In this bird repellent, the bird repellent is always volatilized, which will accelerate the frequency of bird repellent replacement and increase the cost of maintenance. In addition, the description of this bird repellent does not mention how to replace the bird repellent. Once the bird repellent is evaporated, the bird repellent effect of this bird repellent will be greatly reduced. Summary of the invention

[0006] To achieve the above objectives, the present invention proposes a windmill-type composite bird-proofing device for power transmission lines. The multi-mechanism composite bird-proofing device is suitable for a variety of weather scenarios, improves the bird-proofing effect of power transmission lines, and minimizes damage to birds.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A windmill-type composite bird-proofing device for power transmission lines comprises a U-shaped base, wherein the U-shaped base is rotatably connected to a vertical rod bearing rotatable 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; the top of the outer sleeve is connected to a box-type structure, and the box-type structure is rotatably connected to a rotating rod, a rotating drive device is arranged at one end of the rotating rod, and a sound-generating device is connected at the other end, the rotating drive device drives the rotating rod to rotate, and the rotating rod drives the vertical rod to rotate through a transmission device; a containing box and a loading box for loading bird repellent are arranged inside the box-type structure, and the containing box and the loading box are respectively connected to a cover door, the outside of the box-type structure is connected to a tail wing, and the top of the loading box is connected to bird-proof barbs, and the barbs are radially distributed.

[0009] The bird-proof device integrates multiple functions to improve the bird-proof effect. The rotating drive device is connected by a rotating blade and an intermediate ring. The blade is coated with reflective paint to enhance the reflective bird-proof effect. One end of the rotating rod is connected to the rotating drive device, and the other end is connected to the wind whistle. The sound is amplified by airflow resonance to further drive away birds. The vertical rod and the rotating rod are meshed through gears. The rotation of the vertical rod drives the gear inside the outer sleeve, which in turn drives the shaft sleeve and the fan blades to rotate. The reflective sequins on the fan blades reflect at multiple angles and dynamically to enhance visual warning. The box-type structure is equipped with a bird repellent container and a loading box. Under the control of the controller, the bird repellent is automatically released according to the environment. The box-type structure is also equipped with barbs and tail wings to ensure that the device adjusts with the wind direction and maintains the best bird-proof state. The specially designed ring is engraved with spiral lines, imitating threatening patterns such as the eyes of birds of prey. The dynamic effect is significant when rotating, misleading birds into thinking that they are being watched by natural enemies, so that they actively avoid them. The overall design combines visual, auditory and olfactory bird-proofing methods, which is suitable for a variety of environments and occasions and improves the bird-proofing effect.

[0010] As a further technical solution, a driving gear is rotated on the middle part of the vertical rod, and a plurality of through holes are opened on the outer sleeve along the circumferential direction of the outer sleeve. A passive gear is fixed in each through hole, and the passive gear is meshed with the driving gear. The reflective component includes a shaft sleeve and a plurality of fan blades, and raised gear teeth are arranged on the inner ring of the shaft sleeve, and the gear teeth are meshed with the passive gear.

[0011] As a further technical solution, a slide rail is arranged on the outer ring of the outer sleeve, and a groove is arranged on the inner side of the shaft sleeve, and the slide rail cooperates with the groove.

[0012] As a further technical solution, a number of connecting holes are opened on the fan blades, and a rotatable shaft is arranged in the connecting holes, and the shaft is connected to the reflective sequins; the reflective sequins are driven by the shaft to continuously rotate under the action of wind. Since the fan blades are bent at a certain angle, combined with the continuous rotation of the fan blades themselves, they can widely and dynamically reflect light, thereby greatly increasing the reflection range and reflection effect.

[0013] As a further technical solution, the rotary drive device is composed of a plurality of rotating blades connected to an intermediate ring, which is then connected to a rotating rod. The rotating blades are streamlined, and both sides of the rotating blades are coated with reflective paint.

[0014] As a further technical solution, the ring is engraved with spiral lines. When the ring rotates, the spiral lines rotate rapidly with the ring to form a visually dynamic pattern. Under certain angles and lighting conditions, this pattern may resemble the eyes of a bird of prey or other patterns that make birds feel threatened, thereby improving the bird-proofing effect.

[0015] As a further technical solution, the sound-generating device is composed of several wind whistles that rotate with the rotating rod. The wind whistle includes a spring coil, an electromagnet, an air control plate, a small ball and a whistle mouth. The wind whistle is provided with an air inlet, and a small ball is provided inside the wind whistle. The size of the air inlet channel is controlled by the air control plate, the electromagnet and the spring coil. One end of the air control plate is hinged to the wind whistle body, and the other end is connected to the wind whistle body through the spring coil. An electromagnet is provided in the wind whistle body, and the air control plate has magnetism. When air flows into the wind whistle, resonance can be triggered, and the resonance makes the sound of the wind whistle louder and clearer. The air control plate in the wind whistle is regulated by the controller to ensure the stability of the sound frequency, thereby achieving the effect of preventing birds.

[0016] As a further technical solution, the cover control device includes a traction electromagnet, a spring, and a slide rail; the cover is made of a magnetic material, one end of the spring is connected to the box-type structure, and the other end is connected to the cover, the cover is connected to the slide rail, and a traction electromagnet is arranged 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 provided above the box-type structure; a speed sensor is also provided on the rotating rod, and a solenoid valve is installed at the lower part of the barb and the connection part of 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-type structure to power the controller. The above-mentioned barb is a hollow circular tube as a whole, and the lower part of the barb is connected to the loading box loaded with bird repellent. The top of the barb is needle-shaped, and the opening direction of the needle tip is horizontal or downward; a solenoid valve is installed at the lower part of the barb and the connection part of the loading box of the bird repellent to control the release of the bird repellent. The barb can also prevent birds from landing on this bird-proof device, and also prevent birds from nesting here. The controller works by sensing the speed sensor on the rotating part and the photosensitive sensor and humidity sensor on the box-type structure. The tail end of the box-type structure is connected to the tail wing up and down, so that the rotating part is always facing the windward direction, so the device can work continuously when there is wind. A battery is installed inside the box-type structure to power the controller. The speed sensor, light sensor, humidity sensor and controller are used to realize intelligent monitoring and adjustment of the working status of the device. Under adverse conditions such as windless or rainy days, the bird repellent is automatically released through the action of electromagnets and springs, which enhances the environmental adaptability and bird prevention effect of the device.

[0018] The beneficial effects of the present invention are as follows:

[0019] The device combines three different bird-proofing methods: vision, hearing and smell, to form an all-round and multi-level bird-proofing effect. In terms of vision, the reflective sequins on the rotating blades and fan blades reflect light at multiple angles and continuously under the action of wind, and the reflective sequins can also rotate in a breeze, greatly increasing the range and effect of reflection. This dynamic reflective effect forms a strong visual stimulation for birds, making them feel uneasy and actively stay away from the area; in terms of hearing, the resonant sound of the wind whistle produces a loud and clear sound, and the frequency of the sound can be kept stable, which forms an auditory repellent for birds; in terms of smell, under adverse conditions such as no wind or cloudy days, the solenoid valve and cover plate are opened by the controller to automatically release the bird repellent, which enhances the environmental adaptability and bird-proofing effect of the device, avoids unnecessary waste, and prolongs the use time of the bird repellent. In adverse conditions such as rainy days, the solenoid valve and cover plate are closed by the controller to prevent the bird repellent from getting wet in the container box and the loading box, thereby ensuring the bird-proofing effect.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] like Figure 1As shown, this embodiment discloses a windmill-type composite bird-proof device for power transmission lines, comprising a U-shaped base 1, a mounting hole is provided on the lower side wall of the U-shaped base 1, the U-shaped base 1 is rotatably connected to a vertical rod 18 that can rotate around its own axis, the middle of the vertical rod 18 is connected to an outer sleeve 2 through a driving gear 24, the outer sleeve 2 is rotatably connected to the U-shaped base 1 through a bearing, and the top of the vertical rod 18 is connected to a rotating rod 13. The outer sleeve 2 can rotate around the axis itself, the middle of the outer sleeve 2 is connected to a rotating reflective component, the top of the outer sleeve 2 is connected to a box-type structure 9, the box-type structure 9 is connected to the rotating component, a photosensitive sensor 903 and a humidity sensor 904 are arranged above the box-type structure, a receiving box 907 and a loading box 908 for holding bird repellent are arranged inside the box-type structure 9, a cover plate 16 control device is arranged outside the receiving box 907, a controller is arranged inside the box-type structure 9, the tail end of the box-type structure 9 is connected to a tail 11, and the top of the box-type structure 9 is connected to a bird-proof barb 8, and the barbs 8 are radially distributed. The bird-proof device integrates multiple functions to improve the bird-proof effect. The rotating drive device is connected by a rotating blade 6 and an intermediate ring 7, and the blade is coated with a reflective coating to enhance the reflective bird-proof effect. One end of the rotating rod 13 is connected to the rotating drive device, and the other end is connected to the wind whistle 12, which amplifies the sound through airflow resonance to further drive away birds. The vertical rod 18 is engaged with the rotating rod 13 through gears, and the rotation of the vertical rod 18 drives the inner gear of the outer sleeve 2, thereby driving the shaft sleeve 3 and the fan blade 4 to rotate. The reflective sequins 501 on the fan blade 4 reflect light at multiple angles and dynamically to enhance visual warning. The box-type structure 9 is provided with a bird-repellent containing box 907 and a loading box 908, which are regulated by a controller and automatically release the bird-repellent according to the environment. The box-type structure 9 is also equipped with barbs 8 and tail wings 11 to ensure that the device is adjusted with the wind direction to maintain the best bird-proof state. The specially designed ring 7 is engraved with a spiral line 25, imitating threatening patterns such as the eyes of birds of prey. The dynamic effect is significant when rotating, misleading birds into thinking that they are being watched by natural enemies, so that they actively avoid them. The overall design combines visual, auditory and olfactory bird prevention methods, is suitable for a variety of weather scenarios, and improves the bird prevention effect on power transmission lines.

[0035] Further, the rotating part includes a speed sensor 901, a rotating rod 13, a rotating drive device and a sound-generating device. One end of the rotating rod 13 is connected to a rotating drive device that drives the entire rod 13 to rotate. The rotating drive device is composed of a plurality of rotating blades 6 connected to an intermediate ring 7, which is then connected to the rotating rod 13 by the ring 7. The rotating blades 6 are streamlined, and reflective paint is coated on both sides of the rotating blades 6. When the rotating blades 6 rotate, they reflect light to the surroundings, thereby enhancing the bird-proofing effect. The other end of the rotating rod 13 is connected to a sound-generating device, which is composed of a plurality of wind whistles 12 that rotate with the rotating rod 13. When the wind blows the wind whistle 12 or the wind whistle 12 itself rotates, the airflow is effectively guided into the whistle port. At this entrance, the airflow is compressed and accelerated, and transformed into a high-speed and unstable airflow.

[0036] Further, the wind whistle 12 includes a spring coil 1201, an electromagnet 1202, an air control plate 1203, a small ball 1204 and a whistle mouth 1205; the wind whistle 12 is a sphere as a whole, on which a whistle mouth 1205 is arranged, and a small ball 1204 is arranged inside the wind whistle 12; and the channel size of the air inlet 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 wind whistle 12, and the other end is connected to the body of the wind whistle 12 through the spring coil 1201, the electromagnet 1202 is arranged in the body of the wind whistle 12, and the air control plate 1203 has magnetism;

[0037] In the wind whistle 12, the high-speed airflow continues to flow and encounters obstacles, such as the special structure of the ball 1204 or the whistle mouth 1205. These obstacles disturb the airflow, resulting in the formation of vortices and turbulence in the airflow. The vortices and turbulence cause the airflow pressure to change rapidly in space and time. Due to the change in airflow pressure caused by the vortices and turbulence, the ball 1204 will begin to vibrate under the action of the airflow. At the same time, the airflow can also directly rub against the edge of the whistle mouth 1205, causing the whistle mouth 1205 itself to vibrate. Both of these vibration modes can make the wind whistle 12 make a sound. The vibration further causes the air in the sound cavity to vibrate, thereby forming sound waves. These sound waves are constantly reflected and superimposed in the sound cavity, forming a resonance effect. The resonance effect not only enhances the amplitude of the sound wave, but also makes the sound clearer and louder. Finally, the resonated and amplified sound waves are transmitted to the outside air through the opening of the wind whistle 12. When the air flow enters the inlet, it is compressed and accelerated and is regulated by the controller. When the speed sensor 901 detects that the speed of the rotating rod 13 is faster, the air flow entering the wind whistle 12 is larger. 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 wind whistle 12, and the end close to the electromagnet is connected to the wind whistle 12 through a spring coil 1201.

[0038] Furthermore, the air control plate 1203 is closer to the electromagnet 1202 due to the enhanced magnetic effect of the electromagnet 1202, so that the passage after the airflow enters the wind whistle 12 becomes larger, thereby slowing down the speed of the airflow, and controlling the sound emitted by the wind whistle 12 within a certain frequency range. When the rotation speed of the rotating rod 13 is slow, the airflow entering the wind whistle 12 is small, and the controller controls the current of the electromagnet 1202 to decrease, and the magnetism is reduced. Because of the elastic force of the spring coil 1201, the air control plate 1203 is away from the side of the electromagnet 1202, so that the passage after the airflow enters the wind whistle 12 becomes smaller, thereby speeding up the airflow, and making the sound frequency emitted by the wind whistle 12 basically consistent with the frequency emitted when the rotation speed of the rotating rod 13 is fast, so as to maintain the stability of the sound. Because birds are more sensitive to high-frequency sounds, the air inlet of the wind whistle 12, the whistle mouth 1205, etc. can be modified in actual application to ensure that the sound emitted effectively drives away birds.

[0039] The vertical rod 18 is meshed and connected with the rotating rod 13 through a transmission gear 19. When the rotating rod 13 rotates, the vertical rod 18 is driven by the transmission gear 19 and also rotates around its own axis. A driving gear 24 is connected to the middle of the vertical rod 18, and the driving gear 24 rotates with the vertical rod 18. An outer sleeve 2 surrounding the vertical rod 18 is provided on the outside of the vertical rod 18. A plurality of through holes are opened in the middle of the outer sleeve 2. A rotatable passive gear 22 meshed and connected with the driving gear 24 is arranged in the through hole. A raised slide rail 23 is also provided on the outer surface of the outer sleeve 2.

[0040] like Fig. 9 As shown, the rotating reflective component includes a sleeve 3 and a plurality of blades 4. The sleeve 3 is connected to a slide rail 23 protruding from the outer surface of the outer sleeve 2 through an inner groove 21 thereof. At the same time, a protruding gear 20 is provided on the inner side of the sleeve 3 and is meshed and connected with a passive gear 22 in the through hole of the outer sleeve 2. A plurality of blades 4 are also connected to the sleeve 3. The blades 4 form a certain angle with the horizontal plane. A plurality of connecting holes 5 are provided on the blades 4. A rotatable shaft 502 is provided in the connecting hole 5. The shaft 502 is connected to a reflective sequin 501.

[0041] When there is wind, the wind drives the rotating blades 6 to rotate, thereby causing the rotating rod 13 to rotate together. 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 active gear 24 in the middle thereof to rotate together, and the active gear 24 in the middle of the vertical rod 18 will drive the passive gear 22 in the through hole of the outer sleeve 2 to rotate. Because the inner side of the shaft sleeve 3 has protruding gear teeth 20 meshing and connected with the passive gear 22 in the through hole of the outer sleeve 2, and the shaft sleeve 3 and the outer sleeve 2 are connected by a groove 21 and a protruding slide rail 23, when the passive gear 22 in the through hole of the outer sleeve 2 rotates, the shaft sleeve 3 will drive the fan blade 4 on its outer side to rotate around the outer sleeve 2 together, and the reflective sequins 501 in the connecting hole 5 of the fan blade 4 are driven by the rotating shaft 502 to rotate continuously under the action of wind. Since the fan blade 4 is bent at a certain angle, combined with the continuous rotation of the fan blade 4 itself, it can widely and dynamically reflect light, thereby greatly increasing the range and effect of reflection. Driven by the wind, the reflective sequins 501 continuously change their positions and angles as the blades 4 rotate, producing a flashing and reflected light effect. This continuously changing and dynamic visual stimulation is a strong warning signal for birds. The blades 4 are designed to be bent at a certain angle, which not only enhances the rotation efficiency driven by the wind, but also enables the reflective sequins 501 to reflect light from different angles and heights during the rotation process. This multi-angle reflection expands the bird-proof range and ensures an effective bird-repelling effect in a wider area.

[0042] Furthermore, a receiving box 907 and a loading box 908 for loading bird repellent are provided on both sides and the top of the box-shaped structure 9, and a cover door 10 is provided on the upper side of the receiving box 907 and the loading box 908, so that the bird repellent can be replenished or replaced in time. The box-shaped structure 9 is connected to the rotating structure through a bearing 902, and a photosensitive sensor 903, a humidity sensor 904 and a protruding cylinder are provided on the top of the box-shaped structure 9, and bird-proof barbs 8 are provided on the cylinder, showing an outward radial distribution, and the barbs 8 are hollow circular tubes as a whole, and the loading box 908 for loading bird repellent is connected below the barbs 8, and the top of the barbs 8 is needle-shaped, and the opening direction of the needle tip is horizontal or downward to prevent dust or rainwater from clogging.

[0043] Furthermore, a solenoid valve 905 is installed below the barb 8 and at the connection point of the loading box 908 of the bird repellent. When the humidity sensor 904 detects that the humidity of the external environment is too high, such as on a rainy day, the humidity sensor 904 sends a signal to the controller to close the solenoid valve 905 to prevent the bird repellent from getting wet and causing the bird repellent to have a poor bird repellent effect. At the same time, the operation of the solenoid valve 905 is regulated by the speed sensor 901 and the photosensitive sensor 903. When there is no wind or it is cloudy, the controller receives the signal transmitted by the sensor, and the controller opens the solenoid valve 905, so that the smell of the bird repellent can be released through the needle tip of the barb 8 to prevent birds.

[0044] When there is a windy state or a sunny day, the controller receives the signal transmitted by the sensor, and the controller closes the electromagnetic valve 905 to terminate the release of the bird repellent. The barbs 8 can also prevent birds from landing on this bird-proof device, and also prevent birds from building nests here. The box-type structure 9 is fixedly connected to the outer sleeve 2, and the tail end of the box-type structure 9 is connected to the tail wing 11 up and down. When the direction of action of the wind force changes, the tail wing 11 will first be affected by the wind force and drive the entire box-type structure 9 and the outer sleeve 2 to rotate, thereby accurately and quickly showing the direction of the wind, and the box-type structure 9 is connected with the internal rotating rod 13 by a bearing 902, and the rotating rod 13 is meshed with a transmission gear 19 between the vertical rod 18, and the vertical rod 18 is meshed with a gear between the vertical rod 18 and the outer sleeve 2, and the vertical rod 18 and the outer sleeve 2 are all connected to the U-shaped base 1 by bearing rotation, so when the box-type structure 9 and the outer sleeve 2 rotate, the internal rotating rod 13 and the vertical rod 18 will also rotate together, so that the rotating part is always facing the windward direction, so this device can work continuously when there is a windy state. A battery 906 is installed inside the box-shaped structure to power the controller. When there is wind, the rotation of the rotor blades 6 can charge the battery.

[0045] Further, such as Figure 3 As shown, the control device of the cover 16 outside the bird repellent containing box 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. One end of the springs 14 is connected to the vertical panel and the other end is connected to the cover 16. The cover 16 is connected to the slide rail 15. The cover 16 can move horizontally within the range of the slide rail 15. The vertical surface of the sliding part of the slide rail 15 is L-shaped. 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 from the traction electromagnet 17 and the cover 16. The vertical surfaces at both ends of the slide rail 15 are rectangular to ensure the position of the cover 16 and the traction electromagnet 17.

[0046] The controller works by sensing the speed sensor 901 on the rotating part and the photosensitive sensor 903 on the box-type structure 9. In a windy state or sunny day, the cover plate 16 is in a closed state, and the spring 14 is also in a natural state. In a windless state or cloudy day, the controller energizes the traction electromagnet 17 through the signal transmitted by the speed sensor 901 or the photosensitive sensor 903, so that the traction electromagnet 17 has magnetic attraction to the cover plate 16, and the cover plate 16 will move along the slide rail 15 toward the traction electromagnet 17. At this time, the spring 14 is stretched, and the box-type structure 9 is provided with a container box 907 loaded with bird repellent on both sides. The upper half of the shell covered by the cover plate 16 is provided with a plurality of release holes. At this time, the bird repellent in the container box 907 is volatilized through the release holes. The bird repellent releases a specific smell that disgusts birds, and uses the birds' keen sense of smell and instinctive reaction to threats to stimulate their nervous system or respiratory system, making the birds feel uncomfortable and actively fly away from the area, thereby achieving a repelling effect. In windy conditions or sunny days, the controller receives a signal from the speed sensor 901 or the photosensor 903 to cut off the power to the traction electromagnet 17, which loses its magnetism. The cover 16 returns to its initial position under the action of the spring 14 to cover the release hole on the container 907, thereby ending the volatilization of the bird repellent. When the humidity sensor 904 detects that the humidity of the external environment is too high, such as on rainy days, the humidity sensor 904 sends a signal to the controller to cut off the power to the traction electromagnet 17 and close the cover 16 to prevent the bird repellent from getting wet due to excessive humidity, thereby reducing the bird repellent's anti-bird effect.

[0047] Further, such as Fig.10 As shown, the above-mentioned ring 7 is engraved with a spiral line 25. When the wind blows the rotating blade 6 to rotate, the spiral line 25 on the ring 7 also rotates accordingly. The main function of the spiral line 25 is that its dynamic effect when rotating imitates the eyes of a bird of prey or other patterns that make birds feel threatened. When the spiral line 25 rotates rapidly with the ring 7, its dynamic changes will make birds mistakenly think that it is a bird of prey or other natural enemy watching, so they choose to avoid it, thereby achieving the purpose of bird prevention.

[0048] The above device combines three different bird-proofing methods, namely, vision, hearing and smell, to form an all-round and multi-level bird-proofing effect. In terms of vision, a strong visual warning is produced through reflective paint and dynamically changing reflective sequins on the fan blades; in terms of hearing, the resonant sound of the wind whistle produces a loud and clear sound, and the frequency of the sound can be kept stable, which can form an auditory repellent for birds; in terms of smell, bird repellent is released under specific conditions, and birds are repelled by their disgust reaction to specific odors. The reflective sequins on the rotating blades and fan blades reflect light at multiple angles and continuously under the action of wind, greatly increasing the range and effect of the reflection. This dynamic reflective effect forms a strong visual stimulation for birds, making them feel uneasy and actively stay away from the area. The device is connected by gear meshing and bearings to achieve continuous operation in windy conditions. The design of the tail enables the device to accurately and quickly respond to changes in wind direction, keep the rotating parts always facing the windward direction, and ensure the maximum bird-proofing effect. The speed sensor, photosensitive sensor, humidity sensor and controller are used to realize intelligent monitoring and adjustment of the working status of the device. Under unfavorable conditions such as no wind or cloudy days, the solenoid valve and cover are opened by the controller to automatically release the bird repellent, which enhances the environmental adaptability and bird prevention effect of the device. Under unfavorable conditions such as rainy days, the solenoid valve and cover are closed by the controller to prevent the bird repellent from getting wet in the container box and the loading box, thereby ensuring the bird prevention effect. The device fully considers the requirements of environmental protection and energy saving during its design and use. For example, the release of the bird repellent is carried out under specific conditions, avoiding unnecessary waste and environmental pollution. The structural design of the device is flexible and changeable, and is suitable for a variety of environments and occasions. Whether it is farmland, orchards, airports, power facilities, or other places that require bird prevention, the actual needs can be met by adjusting and optimizing the configuration and parameters of the device.
