Description

Technical Field

[0001] This utility model relates to the field of bird-proof spiked plate technology, and in particular to bird-proof spiked plate for tension insulator strings. Background Technology

[0002] Tension insulator strings are critical components in transmission lines, and their safe and stable operation directly affects the reliability of the power system. When birds perch and nest near tension insulator strings, their droppings or fallen nesting material can cause flashover of the insulator strings, leading to line faults. Bird-proofing spikes are installed on tension insulator strings, using spikes to form a physical barrier to prevent birds from approaching and perching, thereby reducing the impact of bird damage on transmission lines. This is an important protective measure to ensure the safe operation of transmission lines. In existing technology, to adapt to the protection needs of different installation locations, bird-proofing spikes for tension insulator strings often adopt a scissor-type structure for telescopic adjustment. By folding and unfolding the scissor plate, the distribution range of the spikes is changed to cover the potential bird activity area around the insulator string.

[0003] Currently, the scissor lift plates are connected to the mounting components on both sides only through a single hinge point. The stress points of the entire scissor lift structure are too concentrated, and the connection strength is insufficient to withstand the test of complex outdoor environments. When encountering strong wind impacts, gaps are prone to loosening at the hinge points. If struck by birds, long-term accumulation may cause plastic deformation or displacement of the entire scissor lift plate, resulting in uneven distribution density of the barbs. This creates a protective blind spot directly above or to the side of the insulator string, allowing birds to approach the insulator string through these uncovered gaps, continuing to cause bird damage risks such as nesting and defecating. This seriously weakens the protective effect on the tension insulator string and makes it difficult to meet the safety requirements for the long-term stable operation of transmission lines. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bird-proof spike plate for tension insulator strings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bird-proof spike plate for tension insulator strings, comprising two mounting plates, with a scissor-type telescopic plate hinged to the inner side of the two mounting plates, spikes fixedly installed at the hinge points at the upper end of the scissor-type telescopic plate, and a retractable protection structure provided at the bottom of both sides of the scissor-type telescopic plate.

[0006] The retractable support structure includes two sector plates, each with an arc-shaped groove extending through its surface. Two guide rods are fixedly installed on the bottom of both sides of the scissor-type telescopic plate. The guide rods are snapped into the inner side of the arc-shaped grooves. A sector-shaped rack plate is provided at the axial position of the bottom of the sector plate. A connecting plate is fixedly installed at the bottom of both guide rods. A sleeve is fixedly installed on the other side of the connecting plate. A guide gear is rotatably provided at the upper end of the sleeve. A locking structure is provided at the bottom of the sector-shaped rack plate.

[0007] The locking structure includes a locking gear, which is fixedly installed on the upper end of the outer surface of the sleeve, and an adjusting screw is internally threaded at the middle position of the fan-shaped rack plate.

[0008] Preferably, a shaft is fixedly installed at the bottom of the guide gear. The shaft passes through and is rotatably disposed inside the connecting plate on the side away from the guide rod. When the fan-shaped rack plate is aligned with the two guide gears, the fan-shaped rack plate and the guide gear mesh with each other.

[0009] Preferably, the top of the adjusting screw is rotatably mounted on the lower surface of the sector plate, and a handle is fixedly installed at its bottom. Guide posts are fixedly installed at both ends of the bottom of the sector plate.

[0010] Preferably, the two sides of the fan-shaped rack plate are slidably disposed on the surfaces of the two guide posts, and when the fan-shaped rack plate is aligned with the two locking gears, the two gears mesh with each other to lock the position of the connecting plate.

[0011] Preferably, two fixing plates are fixedly installed on the middle of the side of each of the two mounting plates near the scissor-type telescopic plate, and pins are fixedly installed on the middle of the inner side of the two fixing plates. The intersection of the two sides of the scissor-type telescopic plate is rotatably mounted on the surface of the pins.

[0012] Preferably, a limiting post is fixedly installed at the bottom of the pin, and a circular hole adapted to the limiting post is opened at the axial position of the sector plate. The sector plate is rotatably installed on the surface of the limiting post through the circular hole.

[0013] Preferably, the axial positions of the arc-shaped groove and the pin coincide, so that when the scissor-type telescopic plate is stretched, it drives the two guide posts to slide inside the arc-shaped groove.

[0014] Preferably, when the sector-shaped rack plate meshes with the two locking gears, the rotation axis of the two connecting plates switches from the sector-shaped plate to the axis of the two locking gears, thereby locking the two guide posts.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting up a shrinkage protection structure, when the scissor-type telescopic plate is stretched or retracted, the guide rods at the bottom of both sides will slide along the arc groove on the surface of the fan-shaped plate. At the same time, the guide gear moves with the connecting plate. When the fan-shaped rack plate is aligned with the guide gear, the two mesh with each other. With the help of the meshing transmission of the gear and rack, the movement trajectory of the scissor-type telescopic plate is precisely guided. The influence of external forces is offset by trajectory constraints, effectively reducing the deformation and displacement of the scissor plate caused by external forces.

[0017] 2. By setting a locking structure, turning the handle causes the adjusting screw to drive the fan-shaped rack plate to slide along the guide post. After engaging with the locking gear, the rotation axis of the connecting plate switches to the axis of the locking gear, so that the movement trajectory of the connecting plate is restricted by the locking gear and can no longer rotate relative to each other, thus locking the guide post. After telescopic positioning, a reliable lock is formed. After positioning, a reliable lock is formed, which can effectively resist the impact of external forces such as wind and bird collisions, provide stable support for the overall structure, maintain the preset protective posture of the needle, and prevent changes in the protection range caused by the offset of the scissor plate.

[0018] 3. The scissor-type telescopic plate is rotatably mounted on the pin surface at the intersection of its two sides, allowing the scissor-type telescopic plate to deflect around the pin. When the scissor-type telescopic plate needs to be adjusted in angle due to installation requirements, the fan-shaped plate can rotate synchronously around the limiting post. The arc groove on its surface always remains in a matching state with the guide rod, ensuring that the sliding of the guide rod in the arc groove is not affected by the angle deviation. This achieves stable installation of the bird spike plate under the offset angle and meets the adjustment requirements of the bird spike plate angle in different installation scenarios.

[0029] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0031] Example: Reference Figures 1-5 The tension insulator string bird-proof spike plate includes two mounting plates 1. The inner sides of the two mounting plates 1 are hinged with scissor-type telescopic plates 21. The hinge points at the upper end of the scissor-type telescopic plates 21 are fixedly installed with spikes 22. The bottom sides of the scissor-type telescopic plates 21 are provided with retractable protection structures 3.

[0032] The retractable protection structure 3 includes two sector plates 301. The surface of each sector plate 301 is provided with an arc groove 302. Two guide rods 303 are fixedly installed on the bottom of both sides of the scissor-type telescopic plate 21. The guide rods 303 are snapped into the inner side of the arc groove 302. A sector rack plate 305 is provided at the axial position of the bottom of the sector plate 301. A connecting plate 306 is fixedly installed at the bottom of each of the two guide rods 303. A sleeve 307 is fixedly installed on the other side of the connecting plate 306. A guide gear 308 is rotatably provided at the upper end of the sleeve 307. A locking structure 4 is provided at the bottom of the sector rack plate 305.

[0033] The locking structure 4 includes a locking gear 401, which is fixedly installed on the upper part of the outer surface of the sleeve 307. An adjusting screw 403 is internally threaded at the middle position of the fan-shaped rack plate 305.

[0034] Specifically: During use, the stretching or contraction of the scissor-type telescopic plate 21 will drive the guide rods 303 on both sides of its bottom to move synchronously. The guide rods 303 slide in the arc grooves 302 on the surface of the sector plate 301. The arc grooves 302 constrain and guide the movement of the guide rods 303, ensuring that the scissor-type telescopic plate 21 stretches and contracts along a preset trajectory. At the same time, the movement of the guide rods 303 drives the connecting plate 306 to move, and the connecting plate 306 drives the sleeve 307 and the guide gear 308 at the upper end of the sleeve 307 to move together. Under normal conditions, the sector rack plate 305 and the guide gear 308 are aligned and mesh with each other. By utilizing the meshing transmission characteristics of the rack and pinion, the movement of one side of the scissor arm is accurately transmitted to the other side, ensuring that the movement of the two scissor arms is consistent, so that the needles 22 can be evenly distributed to achieve effective protective coverage.

[0035] A shaft 309 is fixedly installed at the bottom of the guide gear 308. The shaft 309 passes through and rotatably resides inside the connecting plate 306 on the side away from the guide rod 303. When the sector rack plate 305 is aligned with the two guide gears 308, the sector rack plate 305 and the guide gears 308 mesh with each other. The top of the adjusting screw 403 is rotatably located on the lower surface of the sector plate 301, and a handle 404 is fixedly installed at its bottom. Guide posts 402 are fixedly installed at both ends of the bottom of the sector plate 301. The two sides of the sector rack plate 305 are slidably located on the surfaces of the two guide posts 402 respectively. When the sector rack plate 305 is aligned with the two locking gears 401, the two mesh with each other to lock the position of the connecting plate 306.

[0036] Specifically: During operation, when the scissor-type telescopic plate 21 is extended or retracted, the movement of the guide rod 303 drives the connecting plate 306 to move. The shaft 309, which runs through the connecting plate 306 away from the guide rod 303, moves along with it. The guide gear 308 at the top of the shaft 309 moves synchronously. Since the shaft 309 is rotatably located inside the connecting plate 306, the guide gear 308 can rotate flexibly. When the fan-shaped rack plate 305 is aligned with the two guide gears 308, they mesh with each other. The meshing transmission of the gear and rack ensures the smoothness of the extension and retraction process. When the adjusting screw 403 is rotated, since the fan-shaped rack plate 305 is threadedly connected to the adjusting screw 403, the adjusting screw 403... Rotation is converted into linear motion of the sector rack plate 305 along its own length. Under the guidance of the guide post 402, the sector rack plate 305 slides stably. When the sector rack plate 305 slides to a position aligned with the locking gear 401, the two mesh with each other. At this time, the rotation axis of the connecting plate 306 changes from the sector plate 301 to the axis of the locking gear 401. The meshing relationship between the locking gear 401 and the sector rack plate 305 restricts the rotation of the connecting plate 306. After the scissor-type telescopic plate 21 is positioned, a reliable lock is formed, which can effectively resist the impact of external forces such as wind and bird collisions, provide stable support for the overall structure, maintain the preset protective posture of the needle, and prevent changes in the protection range caused by the offset of the scissor plate.

[0037] Two fixing plates 23 are fixedly installed on the middle of one side of the two mounting plates 1 near the scissor-type telescopic plate 21. A pin 24 is fixedly installed on the middle of the inner side of the two fixing plates 23. The two sides of the scissor-type telescopic plate 21 are respectively rotatably installed on the surface of the pin 24. A limit post 304 is fixedly installed at the bottom of the pin 24. A round hole adapted to the limit post 304 is opened at the axial position of the sector plate 301. The sector plate 301 is rotatably installed on the surface of the limit post 304 through the round hole.

[0038] The axial positions of the arc groove 302 and the pin 24 coincide, so that when the scissor-type telescopic plate 21 is stretched, it drives the two guide posts 402 to slide inside the arc groove 302. When the fan-shaped rack plate 305 meshes with the two locking gears 401, the rotation axis of the two connecting plates 306 switches from the fan-shaped plate 301 to the axis of the two locking gears 401, thereby locking the two guide posts 402.

[0039] Specifically: During operation, the intersection of the two sides of the scissor-type telescopic plate 21 rotates around the surface of the pin 24, providing a stable rotation center for the telescopic movement of the scissor-type telescopic plate 21. At the same time, the limiting post 304 at the bottom of the pin 24 and the sector plate 301 rotate around the limiting post 304 through the round hole, so that the sector plate 301 can rotate synchronously with the angle adjustment of the scissor-type telescopic plate 21. Since the arc groove 302 coincides with the axis of the pin 24, when the scissor-type telescopic plate 21 is stretched, the guide rods 303 at the bottom of both sides slide along the arc groove 302. The trajectory of the arc groove 302 is consistent with the rotation center of the scissor-type telescopic plate 21, ensuring smooth sliding of the guide rods 303 and avoiding motion interference.

[0040] The working principle of this utility model is as follows: In actual use, the two mounting plates 1 are first fixed at the corresponding positions of the tension insulator string. If the angle of the bird spike plate needs to be adjusted in the installation scenario, the scissor-type telescopic plate 21 can be deflected around the pin 24. During this process, the fan-shaped plate 301 rotates synchronously around the limiting post 304 through the round hole. The arc groove 302 on its surface is always matched with the guide rod 303, ensuring that the guide rod 303 slides normally in the arc groove 302, and ensuring that the retraction protection structure 3 and the locking structure 4 can still work stably in the angular offset state.

[0041] After determining the installation location, adjust the telescopic state of the scissor-type telescopic plate 21 according to the specifications of the insulator string. During the adjustment process, the scissor-type telescopic plate 21 stretches or contracts, and the guide rods 303 at the bottom of both sides slide along the arc grooves 302 on the surface of the fan-shaped plate 301. At the same time, the guide gear 308 moves synchronously with the connecting plate 306. Under normal conditions, the fan-shaped rack plate 305 is aligned with the guide gear 308, and the two mesh with each other. With the help of the meshing transmission characteristics of the gear and rack, the movement trajectory of the scissor-type telescopic plate 21 is precisely guided, so that the spikes 22 are evenly distributed to cover the protected area.

[0042] After the scissor-type telescopic plate 21 is adjusted to the appropriate length, the handle 404 is turned to drive the adjusting screw 403 to rotate. The adjusting screw 403 drives the sector rack plate 305 to slide along the guide post 402. When the sector rack plate 305 is aligned and engaged with the locking gear 401, the rotation axis of the two connecting plates 306 is switched from the sector plate 301 to the axis of the locking gear 401. At this time, the movement trajectory of the connecting plates 306 is restricted by the locking gear 401 and cannot rotate relative to each other, thereby locking the guide post 402 and fixing the scissor-type telescopic plate 21 in the current telescopic position. After positioning, a reliable lock is formed, which can effectively resist the impact of external forces such as wind and bird collisions, provide stable support for the overall structure, maintain the preset protective posture of the needle, and prevent changes in the protection range caused by the offset of the scissor plate.
