Description

Technical Field

[0001] This invention relates to the field of overhead power transmission line protection technology, specifically a track-mounted telescopic bird-proof baffle. Background Technology

[0002] The crossarms and insulator string areas of overhead transmission lines are high-frequency areas for birds to nest and perch. Foreign objects such as twigs and wires pecked at by birds during nesting can easily cause short circuits in the lines, and conductive channels formed by dripping bird droppings can easily lead to flashover faults, seriously affecting the safe and stable operation of transmission lines. To ensure the safety of the insulator string area of ​​transmission lines, bird-proof barriers are usually installed in the insulator string area. However, existing bird-proof barriers are mostly fixed-size integrated structures, which have the following drawbacks: First, the protection range is fixed and cannot be adapted to crossarm or insulator string layouts with different spacings; Secondly, it is difficult to disassemble after installation, and the entire line needs to be removed during maintenance, which increases the risk and workload of working at height. Third, relying solely on physical barriers to prevent birds is a single-faceted method of bird deterrence, and birds can easily adapt to it after long-term use. Fourth, the connection structure has poor adaptability and cannot be compatible with crossarm dimensions of different specifications.

[0003] Chinese patent CN217364421U discloses a telescopic bird-proof plate, which includes a sliding plate and a baffle. The sliding plate has warning stickers and wear-resistant strips symmetrically arranged at both ends. The baffle has a groove, and the two ends of the sliding plate are respectively arranged in the groove to form a sliding pair with the baffle. Although the above technical solution has a telescopic bird-proof plate, it adopts a simple sliding structure and lacks a reliable limiting and locking mechanism. It is easy to loosen and shift after telescopic adjustment. Moreover, it does not take into account the actual installation and maintenance needs of power transmission lines, and has problems such as cumbersome installation and insufficient protective stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a track-mounted telescopic bird deterrent, which has the advantages of flexible adjustment of the protection range, quick assembly and disassembly, compatibility with multiple crossbeam specifications, and multiple bird deterrents.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A track-mounted telescopic bird-proof barrier includes a bird-proof barrier body, a track telescopic mechanism, and a crossbeam connecting assembly; The bird-proof baffle body includes a main baffle and a telescopic secondary baffle. There are two telescopic secondary baffles, which are symmetrically arranged on both sides of the main baffle. Both the main baffle and the telescopic auxiliary baffle adopt an arc-shaped concave surface design, and the arc curvature of the main baffle and the telescopic auxiliary baffle is consistent. The telescopic auxiliary baffle is slidably connected to the main baffle via a track telescopic mechanism, thereby enabling adjustment of the bird protection range; The crossarm connecting assembly is fixed to the back of the main baffle and is used to detachably install the bird-proof baffle body onto the crossarm of the transmission line.

[0007] Preferably, a ball-head plunger is fitted into the end of the sliding block, and a plunger spring is provided between the ball-head plunger and the sliding block. The bidirectional slide rail is provided with positioning holes spaced apart along its length. When the telescopic auxiliary baffle is extended to a preset position, the ball-head plunger is engaged in the corresponding positioning hole.

[0008] Preferably, the crossarm connecting assembly includes a bracket fixedly connected to the inner side of the main baffle. The bracket and the main baffle are fixed by bolts. A bidirectional synchronous drive is provided at the bottom of the bracket. An anti-slip clamp is connected to the output end of the bidirectional synchronous drive. The bidirectional synchronous drive is used to drive the two anti-slip clamps to move closer or further apart. A rubber anti-slip pad is provided on the inner side of the anti-slip clamp. The surface of the rubber anti-slip pad is provided with anti-slip texture.

[0009] Preferably, the bidirectional synchronous drive component includes a linkage screw and a drive knob rotatably connected to the bottom end of the bracket. The two ends of the linkage screw have opposite thread directions, and threaded sliders are threadedly connected to the two ends of the linkage screw respectively. Guide rods are also fixedly connected to both sides of the bottom end of the bracket. The threaded sliders are slidably connected to the outside of the guide rods. Anti-slip plates are fixedly connected to the bottom of the threaded sliders. The drive knob is fixedly connected to the middle of the linkage screw. Rotating the drive knob can realize the synchronous centering and clamping of the two anti-slip plates.

[0010] Preferably, both the main baffle and the telescopic auxiliary baffle are coated with a reflective coating. The top of the main baffle is provided with a wind-driven rotating component. The wind-driven rotating component includes a support base fixedly connected to the top of the main baffle. A rotating cylinder is rotatably connected to the top of the support base. An inner shaft is fixedly connected to the shaft of the rotating cylinder. Wind cups are evenly distributed around the top circumference of the inner shaft. The rotating cylinder includes a protruding part and a concave part. A striking spring adapted to the rotating cylinder is fixedly connected to the top of the support base. When the rotating cylinder rotates, the striking spring is lifted with the protruding part and intermittently strikes the concave part to produce a buzzing sound.

[0011] Preferably, the main baffle has an insulator string clearance opening in the middle, and the edge of the insulator string clearance opening is provided with an elastic sealing gasket; the telescopic auxiliary baffle has an arc-shaped edge at the end away from the main baffle.

[0012] Preferably, the back of the main baffle is provided with reinforcing ribs, which include longitudinal ribs and transverse ribs, and the longitudinal ribs and transverse ribs are distributed in a cross shape. The reinforcing ribs are integrally formed with the main baffle.

[0013] Preferably: a spiral blade is fixedly connected to the inner section of the inner shaft extending to the inner side of the support base; a collar is sleeved on the outside of the spiral blade; a lifting rod adapted to the spiral blade is fixedly connected to the inside of the collar; the spiral blade is set to 180°~320°; the spiral blade is used to lift the collar via the lifting rod; when the lifting rod slides to the notch of the spiral blade, the collar falls downwards; a counterweight is fixedly connected to the bottom of the collar; a return spring is provided between the collar and the support base; a positioning ring is movably connected to the outside of the counterweight; a strike plate is fixedly connected to the bottom of the positioning ring; reinforcing tubes are fixedly connected to the outer sides of the support base; the reinforcing tubes are welded to the bottom of the main baffle; the reinforcing tubes are fixedly connected to the strike plate; and several vibrating plates are provided inside the reinforcing tubes.

[0014] The beneficial effects of this invention are: 1. This track-mounted telescopic bird guardrail uses sliding blocks and bidirectional slide rails to achieve smooth sliding of the telescopic secondary guardrail. When the telescopic secondary guardrail slides to both sides, it extends to both sides along the arc direction of the main guardrail. When the telescopic secondary guardrail is unfolded, the maximum protective width can reach twice that of the main guardrail, so that the telescopic secondary guardrails on both sides can effectively cover both sides of the crossarm, ensuring the protection range of the main body of the bird guardrail. When retracted, it facilitates the maintenance of the line without the need to completely dismantle the device, thus ensuring the effectiveness of the device.

[0015] 2. This track-mounted telescopic bird-proof baffle uses a linkage screw to drive two anti-slip plates to clamp synchronously, allowing the crossarm connection assembly to adapt to crossarms of different widths. Installation and disassembly only require rotating the drive knob, eliminating the need for high-altitude welding operations, reducing operational risks, increasing the flexibility of the main body installation of the bird-proof baffle, and facilitating subsequent disassembly and maintenance.

[0016] 3. This track-mounted telescopic bird deterrent baffle uses natural wind power to continuously drive the rotating drum, which generates a buzzing and vibrating sound during rotation. Simultaneously, a reflective coating reflects sunlight, creating a dual sound and light bird deterrent effect, improving reliability and ensuring protection of the insulator string area. Furthermore, the baffle and telescopic auxiliary baffle are designed with an arc-shaped concave surface, providing physical structural protection and achieving physical interception. Combined with sound and light bird deterrents, this creates a triple bird deterrent mechanism, effectively preventing birds from stopping and nesting, and reducing the risk of bird droppings flashover.

[0017] 4. This track-mounted telescopic bird-repellent baffle effectively transmits vibration through the impact plate, reinforcing tube, and vibrating plate. During the rotation of the rotating drum, the drum drives the counterweight to continuously strike the impact plate, causing the main baffle to vibrate continuously. This effectively improves the bird-repelling effect of the main baffle. In windy and rainy weather, the main baffle vibrates under the action of the impact plate, which effectively improves the scouring effect of rainwater on the main baffle, thereby ensuring the service life and performance of the reflective coating of the main baffle and the telescopic secondary baffle.

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1 - Figure 6 A track-mounted telescopic bird-proof baffle includes a bird-proof baffle body, a track telescopic mechanism, and a crossbeam connecting assembly; The bird-proof baffle body includes a main baffle 1 and a telescopic secondary baffle 2. There are two telescopic secondary baffles 2, which are symmetrically arranged on both sides of the main baffle 1. Both the main baffle 1 and the telescopic auxiliary baffle 2 adopt an arc-shaped concave surface design, and the arc curvature of the main baffle 1 and the telescopic auxiliary baffle 2 is consistent; The telescopic secondary baffle 2 is slidably connected to the main baffle 1 through a track telescopic mechanism, so as to realize the adjustment of the bird protection range. The surface of the telescopic secondary baffle 2 is provided with a wear-resistant coating. The crossarm connecting assembly is fixed to the back of the main baffle 1 and is used to detachably install the bird-proof baffle body onto the crossarm of the transmission line.

[0022] It should be noted that the arc-shaped concave design of the main baffle 1 and the telescopic secondary baffle 2 can guide bird droppings to slide down the concave surface and avoid accumulation; both the main baffle 1 and the telescopic secondary baffle 2 are made of high-strength lightweight alloy materials, which have structural strength and lightweight characteristics.

[0023] refer to Figure 1 and Figure 6 In an optional embodiment, the track telescopic mechanism includes a bidirectional slide rail 3 fixedly connected to the inner side of the main baffle 1, and a sliding block 4 fixedly connected to the top of the telescopic auxiliary baffle 2. The bidirectional slide rail 3 extends along the length direction of the main baffle 1, and the sliding block 4 is slidably connected to the outside of the bidirectional slide rail 3.

[0024] The telescopic auxiliary baffle 2 is smoothly slidable by the sliding block 4 and the bidirectional slide rail 3. When the telescopic auxiliary baffle 2 slides to both sides, it extends to both sides along the arc direction of the main baffle 1. When the telescopic auxiliary baffle 2 is unfolded, the maximum protection width can reach twice that of the main baffle 1, so that the telescopic auxiliary baffles 2 on both sides can effectively cover both sides of the crossarm, ensuring the protection range of the main body of the bird-proof baffle. When it is retracted, it is convenient for the maintenance of the line without the need to completely dismantle the device, thus ensuring the effectiveness of the device.

[0025] refer to Figure 2In an optional embodiment, a ball-head plunger 5 is fitted into the end of the sliding block 4, and a plunger spring 51 is provided between the ball-head plunger 5 and the sliding block 4. The bidirectional slide rail 3 is provided with positioning holes 6 spaced apart along its length. When the telescopic auxiliary baffle 2 is extended to a preset position, the ball-head plunger 5 is engaged in the corresponding positioning hole 6.

[0026] It should be noted that the positioning hole 6 includes a preset positioning hole 6 in the unfolded position and a preset positioning hole 6 in the retracted state.

[0027] Furthermore, positioning holes 6 are still evenly provided between the preset positioning holes 6 in the retracted state and the preset positioning holes 6 in the unfolded state, so as to ensure that the telescopic sub-baffle 2 can be locked in any preset position, so as to achieve the effect of flexibly adjusting the position of the telescopic sub-baffle 2 and effectively preventing displacement caused by external forces such as wind.

[0028] refer to Figure 1 and Figure 3 In an optional embodiment, the crossarm connecting assembly includes a bracket 7 fixedly connected to the inner side of the main baffle 1. The bracket 7 and the main baffle 1 are fixed by bolts. A bidirectional synchronous drive 8 is provided at the bottom end of the bracket 7. An anti-slip clamp 9 is connected to the output end of the bidirectional synchronous drive 8. The bidirectional synchronous drive 8 is used to drive the two anti-slip clamps 9 to move closer or further apart. A rubber anti-slip pad 10 is provided on the inner side of the anti-slip clamp 9. The surface of the rubber anti-slip pad 10 is provided with anti-slip texture.

[0029] The bidirectional synchronous drive component 8 drives the anti-slip clamps 9 on both sides to clamp the outside of the crossarm. The rubber anti-slip pads 10 on the inside of the anti-slip clamps 9 can increase friction, improve the fixing stability, and effectively avoid damage to the surface of the crossarm.

[0030] refer to Figure 3 In an optional embodiment, the bidirectional synchronous drive component 8 includes a linkage screw 81 and a drive knob 82 rotatably connected to the bottom end of the bracket 7. The two ends of the linkage screw 81 have opposite thread directions, and threaded sliders 83 are threadedly connected to the two ends of the linkage screw 81 respectively. Guide rods 84 are also fixedly connected to both sides of the bottom end of the bracket 7. The threaded sliders 83 are slidably connected to the outside of the guide rods 84. Anti-slip clamps 9 are fixedly connected to the bottom of the threaded sliders 83. The drive knob 82 is fixedly connected to the middle of the linkage screw 81. Rotating the drive knob 82 can realize the synchronous centering and clamping of the two anti-slip clamps 9.

[0031] Specifically, when installing the bird-proof baffle body to the top of the crossarm, the drive knob 82 can be rotated. The drive knob 82 drives the linkage screw 81 to rotate, and the linkage screw 81 drives the two anti-slip clamps 9 to clamp synchronously. It can be adapted to crossarms with specifications of 50-200mm, so that the crossarm connecting components can be adapted to crossarms of different widths. Moreover, installation and disassembly only require rotating the drive knob 82, eliminating the need for high-altitude welding operations, reducing operational risks, increasing the flexibility of the bird-proof baffle body installation, and facilitating subsequent disassembly and maintenance.

[0032] refer to Figure 4 and Figure 7 In one optional embodiment, the exterior of both the main baffle 1 and the telescopic secondary baffle 2 are coated with a reflective coating. The top of the main baffle 1 is provided with a wind-driven rotating component 11. The wind-driven rotating component 11 includes a support seat 111 fixedly connected to the top of the main baffle 1. A rotating cylinder 112 is rotatably connected to the top of the support seat 111. An inner shaft 113 is fixedly connected to the shaft of the rotating cylinder 112. Wind cups 114 are evenly distributed around the top circumference of the inner shaft 113. The rotating cylinder 112 includes a protrusion 1121 and a concave portion 1122. A striking spring 115 adapted to the rotating cylinder 112 is fixedly connected to the top of the support seat 111. When the rotating cylinder 112 rotates, the striking spring 115 is lifted with the protrusion 1121 and intermittently strikes the concave portion 1122 to produce a buzzing sound.

[0033] It should be noted that the wind cup 114 is rotated by natural wind power. The wind cup 114 drives the rotating cylinder 112 to rotate through the inner shaft 113. During the rotation of the rotating cylinder 112, the protrusion 1121 pushes up the striking spring 115. When the striking spring 115 is disengaged from the position of the protrusion 1121, it strikes the surface of the concave part 1122 under the action of elasticity.

[0034] The rotating drum 112 is continuously driven by natural wind, and a buzzing sound is generated during the rotation of the drum 112. At the same time, the reflective coating reflects sunlight, forming a dual sound and light bird-repelling effect, which improves the reliability of bird repelling and ensures the protection effect on the insulator string area.

[0035] Furthermore, the main baffle 1 and the telescopic secondary baffle 2 are designed with an arc-shaped concave surface. The arc-shaped surface provides physical structural protection and achieves the effect of physical interception. Combined with sound and light to deter birds, a triple bird deterrence mechanism is achieved, which effectively prevents birds from stopping to nest and reduces the risk of bird droppings flashover.

[0036] refer to Figure 1 , Figure 5 and Figure 6 In one optional embodiment, the main baffle 1 has an insulator string clearance opening 12 in the middle, and the edge of the insulator string clearance opening 12 is provided with an elastic sealing gasket; the telescopic auxiliary baffle 2 has an arc-shaped edge 21 at the end away from the main baffle 1.

[0037] The curved edge 21 is used to guide bird droppings to slide down the curved surface.

[0038] refer to Figure 5 The main baffle 1 has a reinforcing rib 13 on its back. The reinforcing rib 13 includes longitudinal ribs 131 and transverse ribs 132. The longitudinal ribs 131 and transverse ribs 132 are distributed in a cross shape. The reinforcing rib 13 is integrally formed with the main baffle 1.

[0039] The design of the reinforcing rib 13 greatly enhances the overall strength of the main baffle 1, making it suitable for harsh outdoor environments.

[0040] Example 2, reference Figures 7-9 Based on Embodiment 1, when the main area where the bird-proof baffle is installed is in a windy environment, a vibration bird deterrent can be further added. Specifically, a spiral blade 116 is fixedly connected to the inner section of the inner shaft rod 113 extending to the inner side of the support base 111. A collar 117 is sleeved on the outside of the spiral blade 116. A lifting rod 118 adapted to the spiral blade 116 is fixedly connected to the inside of the collar 117. The spiral blade 116 is set to 180°~320°. The spiral blade 116 is used to lift the collar 117 through the lifting rod 118. When the lifting rod 118 slides to the notch of the spiral blade 116, the collar 117 falls down. A counterweight block 1110 is fixedly connected to the bottom of the collar 117. A return spring 119 is provided between the collar 117 and the support base 111. A positioning ring 1111 is movably connected to the outside of the counterweight block 1110. A strike plate 1112 is fixedly connected to the bottom of the positioning ring 1111.

[0041] It should be noted that the lower notch of the spiral blade 116 contacts the lifting rod 118. During the rotation of the spiral blade 116, the lifting rod 118 slides along the surface of the spiral blade 116. When the lifting rod 118 slides to the upper notch of the spiral blade 116, the lifting rod 118 slides to the bottom. Then, during the rotation of the spiral blade 116, the bottom of the spiral blade 116 contacts the lifting rod 118 again.

[0042] During the reciprocating up and down movement of the lifting rod 118, the lifting rod 118 drives the collar 117 to move up and down. When the collar 117 moves upward, the collar 117 stretches the return spring 119. When the collar 117 moves downward, the return spring 119 pulls the collar 117 down faster due to the elasticity of the spring.

[0043] When the collar 117 moves up and down, it drives the counterweight 1110 to move up and down. When the counterweight 1110 moves down, it strikes the impact plate 1112. The impact plate 1112 vibrates, causing the surface of the main baffle 1 to vibrate. By generating vibration on the surface of the main baffle 1, the effect of disturbing birds is further increased, achieving four-fold protection: vibration, physical protection, sound, and light.

[0044] It should be further explained that the counterweight 1110 is slidably connected inside the positioning ring 1111, and a radial limit is provided between the counterweight 1110 and the positioning ring 1111. The radial limit can be selected by the cooperation of a groove and a protrusion opened in the axial direction. The positioning ring 1111 is fixedly welded to the inside of the support base 111.

[0045] Furthermore, reinforcing tubes 14 are fixedly connected to the outer sides of the support base 111. The reinforcing tubes 14 are welded to the bottom of the main baffle 1. The reinforcing tubes 14 are fixedly connected to the impact plate 1112. Several vibrating plates 141 are arranged inside the reinforcing tubes 14.

[0046] It should be noted that the reinforcing tube 14 and the vibrating plate 141 are used to transmit the vibration effect of the impact plate 1112, so that the main body of the main baffle 1 can effectively receive and transmit the vibration effect of the impact plate 1112.

[0047] The impact plate 1112 enables the main baffle 1 to effectively transmit vibration through the reinforcing tube 14 and the vibrating plate 141. During the rotation of the rotating drum 112, the rotating drum 112 drives the counterweight block 1110 to continuously strike the impact plate 1112, causing the main baffle 1 to vibrate continuously, thereby effectively improving the bird-repelling effect of the bird-blocking plate.

[0048] Furthermore, in windy and rainy weather, the main body of the bird shield vibrates under the action of the impact plate 1112. The vibration effectively improves the scouring effect of rainwater on the main body of the bird shield, thereby ensuring the service life and performance of the reflective coating of the main baffle 1 and the telescopic secondary baffle 2.

[0049] Device assembly: Fix the bidirectional slide rail 3 to the inside of the main baffle 1, and fix the sliding block 4 to the top of the telescopic auxiliary baffle 2 to ensure that the sliding block 4 and the bidirectional slide rail 3 slide smoothly; The bracket 7 of the crossarm connecting assembly is fixed to the back of the main baffle 1 with bolts, and the bidirectional synchronous drive component 8 and anti-slip clamp 9 are installed. Rubber anti-slip pad 10 is pasted on the inner side of the anti-slip clamp 9. Finally, the wind-driven rotating component 11 is installed on the top of the main baffle 1 to ensure that the rotating drum 112 rotates flexibly.

[0050] Installation process: The staff carries the assembled device to the crossarm of the transmission line, aligns the anti-slip clamp 9 of the crossarm connecting component with both sides of the crossarm, rotates the drive knob 82, and drives the anti-slip clamp 9 to move closer together through the bidirectional synchronous drive component 8 until the rubber anti-slip pad 10 is tightly attached to the crossarm, and the fixing is completed. According to the protection requirements, the telescopic auxiliary baffle 2 is pulled to unfold along the bidirectional slide rail 3. When the ball plunger 5 is inserted into the corresponding positioning hole 6, the telescopic auxiliary baffle 2 is locked to achieve the preset protection range.

[0051] Maintenance and adjustment: When line maintenance is required, push the telescopic auxiliary baffle 2 to slide inward along the bidirectional slide rail 3, so that the ball plunger 5 disengages from the positioning hole 6, and push the telescopic auxiliary baffle 2 to retract below the main baffle 1, exposing the maintenance area; after maintenance is completed, unfold the telescopic auxiliary baffle 2 again and lock it.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
