Technical Field
[0001] This utility model relates to the field of bird-proof equipment technology, and more specifically, to a bird-proof insulating baffle. Background Technology
[0002] Bird-proof insulating baffles are functional protective devices specifically designed for power lines and equipment. Their core function is to simultaneously address the threats of bird damage and ensure insulation safety. They are widely used in critical live parts such as insulator strings, disconnectors, and circuit breakers on 10kV-500kV high-voltage transmission lines. They are core protective accessories for outdoor power grid maintenance. By being installed on insulators, they can protect insulators and some cables. In addition, they can effectively prevent bird droppings (containing highly conductive uric acid) from dripping onto the insulator surface and causing flashover, and prevent foreign objects such as branches and wires used by birds for nesting from coming into contact with live parts and causing short circuits. At the same time, through insulation isolation, they reduce the impact of personnel inspections or the surrounding environment on the insulation performance of the line. They are the core insulation protection equipment for bird damage prevention in power systems. The thickness and length of the sheath covering the transmission line need to be configured according to the line voltage level.
[0003] Current insulating baffles are usually directly clipped onto the outside of the insulator, and are fixed to the outside of the insulator by clamping force. However, the function of this traditional insulating baffle is relatively simple, and birds can still approach the insulator. As a result, bird droppings will be carried by the airflow to the insulator, which will affect the service condition of the insulator and cable and cannot adapt to diverse operating environments. In view of this, we propose a bird-proof insulating baffle. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a bird-proof insulating baffle to solve the current technical problem of birds approaching insulators.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bird-proof insulating baffle, including a bird-proof device and a power transmission component inside the bird-proof device; The power transmission assembly includes an insulator body and a cable body; The bird-proof device includes an insulator cover, and a support mechanism is provided on the top surface of the inner wall of the insulator cover; The support mechanism includes a fixed base and a support frame, and air guide components are provided on both sides of the support mechanism; The air guiding assembly includes an assembly block, an air guiding plate, a conical wind concentrator, and an impact-bearing column. The top surface of the air guiding plate is bonded to the bottom surface of the assembly block. The air guiding assembly also includes a sound-generating structure. The sound-generating structure includes a vibrating plate and a striking part, wherein the striking part is integrally formed on the outer wall of the vibrating plate.
[0006] Preferably, the top of the insulator body is inside the insulator cover, the cable body is on the top surface of the insulator body, and the cable body passes through the fixing base and the support frame; The bird-proof device also includes two snap-fit parts, multiple guide blocks, and two cable covers. The two snap-fit parts are located at the inlet and outlet ends of the insulator cover, respectively. Both the snap-fit parts and the cable covers are snapped onto the outside of the cable body. The cable covers are snapped into the outer wall of the snap-fit parts. The guide blocks are respectively fused to the bottom surface of the insulator cover and the cable cover, and the guide blocks are distributed in a rectangular array.
[0007] Preferably, the outer wall of the fixed base is fused with a support arm, the top surface of the support arm is fused to the top surface of the inner wall of the insulator cover, the fixed base and the support frame are connected by bolts, the support frame is provided with a support ring inside, the support ring is fitted with a support shaft inside, and the bottom surface of the support shaft is threaded to the top surface of the assembly block.
[0008] Preferably, the outer wall of the assembly block is provided with an arc-shaped positioning groove, the inner diameter of which is adapted to the outer diameter of the outer ring of the insulator body, and the outer ring of the insulator body is located inside the arc-shaped positioning groove.
[0009] Preferably, the air guide plate adopts a V-shaped structure design, and conical wind-gathering hoods are fused to the outer walls on both sides of the air guide plate. Parallel impact-receiving columns are fused to the inner wall of the conical wind-gathering hood at equal intervals. The impact-receiving columns are distributed on the upper and lower sides of the striking part. A sound-generating cavity is opened inside the impact-receiving column. The inner wall of the sound-generating cavity adopts an arc shape. The striking part is located in the conical wind-gathering hood, and the end face of the striking part adopts a rounded corner design.
[0010] Preferably, the vibrating plate has a positioning post welded to its outer wall away from the striking part. The outer walls on both sides of the positioning post are welded to the outer wall of the air guide plate and the inner wall of the conical wind-gathering hood, respectively. The vibrating plate includes several curved sections, the bending directions of adjacent curved sections are opposite, and adjacent curved sections are V-shaped.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model combines a V-shaped air guide plate with a conical wind-gathering hood. The V-shaped air guide plate can efficiently collect and disperse airflow, while the conical wind-gathering hood can concentrate wind power and enhance the force on the vibrating plate. The disturbance of the airflow can generate sound, forming a sound wave that is deterrent to birds. It can automatically drive away birds without external power supply, making it suitable for unattended outdoor scenarios. It effectively disperses birds while avoiding interference with the surrounding ecology, thus solving the current problem of birds approaching insulators.
[0012] 2. This utility model also features an integrated design where the striking part and the outer wall of the vibrating plate are integrally formed. This integrated structure prevents the two from loosening or separating during long-term vibration and impact, ensuring structural strength and service life. The striking part is precisely positioned inside the conical wind-gathering shroud and is distributed on the upper and lower sides of the impacted column. When the vibrating plate vibrates under the action of airflow, the striking part moves synchronously with the vibrating plate, continuously and accurately striking the impacted columns on the upper and lower sides, thus producing a crisp impact sound. At the same time, the rounded corner design of the striking part end face effectively reduces frictional loss when impacting the impacted column, lowers the wear rate of the components, and extends the service life of the entire sound-generating structure. The arc-shaped inner wall sound-generating cavity inside the impacted column amplifies the sound generated by the striking part, forming a continuous sound wave that is deterrent to birds. By stimulating birds with sound, it avoids birds from approaching the insulator body and cable body, further solving the problem of birds approaching the insulator body.
[0013] 3. This utility model also designs a combined protective structure of insulator cover and cable cover. The insulator cover can wrap around the top of the insulator body, directly preventing birds from contacting the key parts of the insulator. The cable cover is connected to the insulator cover through a snap-fit part, extending the protection range of the cable body and avoiding faults such as insulator flashover and foreign object short circuit caused by birds landing, nesting or defecating, thus further solving the problem of birds landing.

[0016] like Figures 1 to 7 As shown, the present invention relates to a bird-proof insulating baffle, which includes a bird-proof device 1 and a power transmission component 2 located inside the bird-proof device 1. The power transmission assembly 2 includes an insulator body 21 and a cable body 22. The bird-proof device 1 includes an insulator cover 11. A support mechanism 3 is provided on the top surface of the inner wall of the insulator cover 11. The support mechanism 3 includes a fixed base 32 and a support frame 33. Air guide components 4 are provided on both sides of the support mechanism 3. The air guide component 4 includes an assembly block 41, an air guide plate 43, a conical wind-gathering cover 44, and a strike-bearing column 45. The top surface of the air guide plate 43 is bonded to the bottom surface of the assembly block 41. The air guide component 4 also includes a sound-generating structure 5. The sound-generating structure 5 includes a vibrating plate 52 and a striking part 53. The striking part 53 is integrally formed on the outer wall of the vibrating plate 52. This utility model can prevent bird droppings from causing flashover of the insulator body 21 and foreign objects from nesting causing short circuits in the line. It can also provide insulation and isolation to ensure the performance of the line. Through the cooperation of the air guide plate 43, the conical wind-gathering cover 44, and the sound-generating structure 5, it can automatically emit sound to drive away birds without the need for an external power supply, thus avoiding the advantage of birds approaching.
[0017] Specifically, the top of the insulator body 21 is inside the insulator cover 11, the cable body 22 is on the top surface of the insulator body 21, and the cable body 22 passes through the fixed base 32 and the support frame 33. The bird-proof device 1 also includes two snap-fit parts 12, multiple guide blocks 13, and two cable covers 14. The two snap-fit parts 12 are located at the inlet and outlet ends of the insulator cover 11, respectively. Both the snap-fit parts 12 and the cable covers 14 are snap-fitted to the outside of the cable body 22. The cable covers 14 are snap-fitted to the outer wall of the snap-fit parts 12. The guide blocks 13 are respectively fused to the bottom surface of the insulator cover 11 and the cable cover 14, and the guide blocks 13 are distributed in a rectangular array. The insulator cover 11 forms a protective enclosure around the top of the insulator body 21, directly preventing birds from contacting the insulator body 21. The cable cover 14 maintains a strong connection with the insulator cover 11 through the snap-fit part 12. The cable cover 14 can shield and protect the cable body 22, preventing birds from contacting the shielded part of the cable body 22. The snap-fit part 12 can fill the gap between the insulator cover 11 and the cable body 22. The cable cover 14 can extend the protection range of the cable body 22. The rectangular array of guide blocks 13, through their open shape, can facilitate the snap-fit part 12 or the cable cover 14 to be snapped onto the outside of the cable body 22. The fixing seat 32 and the support frame 33 limit the cable body 22, preventing the cable body 22 from shifting due to outdoor wind, vibration and other factors, ensuring the stability of the power transmission assembly 2.
[0018] Furthermore, a support arm 31 is fused to the outer wall of the fixed base 32, and the top surface of the support arm 31 is fused to the top surface of the inner wall of the insulator cover 11. The fixed base 32 and the support frame 33 are connected by bolts. A support ring 34 is provided inside the support frame 33. The support ring 34 is made of polytetrafluoroethylene (PTFE). The low coefficient of friction of PTFE enables the smooth rotation of the support shaft 35 inside the support ring 34. The support shaft 35 is sleeved inside the support ring 34, and the bottom surface of the support shaft 35 is threaded to the top surface of the assembly block 41. The support arm 31 achieves a stable connection between the fixed base 32 and the insulator cover 11 through fusion. The bolt connection facilitates the disassembly and maintenance of the fixed base 32 and the support frame 33 in the future. The PTFE support ring 34 reduces the rotational resistance of the support shaft 35, allowing the assembly block 41 to adjust its angle with the support shaft 35 to adapt to different wind directions. This ensures that the cone shape of the air guide plate 43 faces the direction of the airflow, ensuring the guiding effect on the ambient airflow.
[0019] It is worth noting that the outer wall of the assembly block 41 is provided with an arc-shaped positioning groove 42. The inner diameter of the arc-shaped positioning groove 42 is adapted to the outer diameter of the outer ring of the insulator body 21, and the outer ring of the insulator body 21 is located inside the arc-shaped positioning groove 42. The adaptation design of the arc-shaped positioning groove 42 and the outer ring of the insulator body 21 can achieve precise positioning of the assembly block 41 on the insulator body 21, avoid the assembly block 41 from shifting due to external forces, ensure that the air guide assembly 4 and the sound generating structure 5 are always in an effective working position, ensure the stable operation of the bird protection function, and further stabilize the position of the insulator cover 11 outside the insulator body 21.
[0020] It is worth mentioning that the air guide plate 43 adopts a V-shaped structure design. Both outer walls of the air guide plate 43 are welded with conical wind concentrators 44. The inner wall of the conical wind concentrators 44 is welded with parallel impact columns 45 at equal intervals. The impact columns 45 are distributed on the upper and lower sides of the striking part 53. The impact columns 45 have sound-generating cavities 46 inside. The inner wall of the sound-generating cavity 46 is arc-shaped. The striking part 53 is located in the conical wind concentrators 44, and the end face of the striking part 53 is designed with rounded corners. The V-shaped wind deflector 43 can collect and guide wind more efficiently, while the conical wind-gathering shroud 44 can gather and disperse wind force, enhancing the force on the vibrating plate 52. When the vibrating plate 52 vibrates, it can cause disturbance to the airflow, thereby causing the surrounding air molecules to make periodic compression and dispersion movements, forming sound waves, which can repel birds on the outside of the insulator cover 11. The vertical distribution of the impact post 45 ensures that the striking part 53 can accurately strike when it vibrates. The sound-emitting cavity 46 of the arc-shaped inner wall can amplify the impact sound, further improving the bird-repelling effect. The rounded corner design can reduce wear when the striking part 53 and the impact post 45 collide, extending the service life of the component.
[0021] It is worth noting that a positioning post 51 is fused to the outer wall of the vibrating plate 52 away from the striking part 53. The outer walls of the positioning post 51 on both sides are fused to the outer wall of the air guide plate 43 and the inner wall of the conical wind concentrator 44, respectively. The vibrating plate 52 includes several curved parts 54, with adjacent curved parts 54 bending in opposite directions and forming a V-shape. The positioning post 51 fixes the vibrating plate 52 between the air guide plate 43 and the conical wind concentrator 44 through bidirectional fusion, ensuring the stability of the vibrating plate 52 during operation. The V-shaped distribution of the curved parts 54 with opposite bending directions enhances the elasticity and vibration amplitude of the vibrating plate 52, allowing the striking part 53 to produce a continuous and powerful impact action, ensuring that the bird-repelling sound is uninterrupted.
[0022] Working Principle: This embodiment provides a bird-proof insulating baffle. In use, the insulator cover 11 forms a protective enclosure around the top of the insulator body 21, directly preventing birds from contacting the insulator body 21. Simultaneously, two locking parts 12 are located at the inlet and outlet ends of the insulator cover 11. Both the locking parts 12 and the cable cover 14 are locked onto the outside of the cable body 22. The cable cover 14 is locked to the outer wall of the locking parts 12, thus providing shielding protection for the cable body 22 and preventing birds from contacting the shielded portion of the cable body 22. The locking parts 12 fill the gap between the insulator cover 11 and the cable body 22. The rectangular array of guide blocks 13, with their open shape, facilitates the locking parts 12 or the cable cover 14 to be fastened onto the cable body. On the outside of the cable body 22, the fixing seat 32 and the support frame 33 limit the cable body 22, preventing it from shifting due to outdoor wind, vibration, and other factors, thus ensuring the stability of the power transmission assembly 2. The support arm 31 achieves a stable connection between the fixing seat 32 and the insulator cover 11 through welding. The fixing seat 32 and the support frame 33 are connected by bolts for easy disassembly and maintenance. The support ring 34 inside the support frame 33 is made of polytetrafluoroethylene (PTFE), which utilizes its low coefficient of friction to allow the support shaft 35 to rotate smoothly within the support ring 34. The bottom surface of the support shaft 35 is threaded to the top surface of the assembly block 41, allowing the assembly block 41 to adjust its angle with the support shaft 35 to adapt to different wind directions and ensure that the conical direction of the air guide plate 43 is aligned with the airflow. The arc-shaped positioning groove 42 on the outer wall of the assembly block 41 is adapted to the outer diameter of the outer ring of the insulator body 21. The outer ring of the insulator body 21 is located inside the arc-shaped positioning groove 42, realizing the precise positioning of the assembly block 41 on the insulator body 21, avoiding the displacement of the assembly block 41 due to external forces, and ensuring that the air guide assembly 4 and the sound generating structure 5 are always in an effective working position. When there is airflow outdoors, the V-shaped air guide plate 43 efficiently collects and guides the wind force. The conical wind concentrator 44 on both sides of the outer wall of the air guide plate 43 gathers and disperses the wind force, enhancing the force on the vibrating plate 52. The positioning post 51 fixes the vibrating plate 52 between the air guide plate 43 and the conical wind concentrator 44 through bidirectional welding, ensuring the stability of the vibrating plate 52 during operation. The vibrating plate 52 has a V-shaped distribution and The bending portion 54 with opposite bending direction enhances the elasticity and vibration amplitude of the vibrating plate 52, so that the striking portion 53 integrally formed on the outer wall of the vibrating plate 52 generates continuous and powerful vibration. The striking portion 53 is distributed inside the conical wind-gathering cover 44 and is located on the upper and lower sides of the impact post 45. During the vibration, the striking portion 53 will hit the impact post 45. The sound-emitting cavity 46 of the arc-shaped inner wall of the impact post 45 can amplify the impact sound. At the same time, the vibration of the vibrating plate 52 causes disturbance to the airflow, pushing the surrounding air molecules to make periodic compression and dispersion movements to form sound waves. The sound can effectively drive away birds outside the insulator cover 11, preventing birds from approaching the insulator body 21 and the cable body 22. In addition, the rounded corner design of the end face of the striking portion 53 can reduce wear when it hits the impact post 45.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
