[0002] Bird deterrent spikes are a product developed to prevent birds from nesting on power transmission towers. They are installed on the upper part of the crossarm of the towers of power transmission and transformation equipment. Composed of multiple steel wires in a spread-out shape, they effectively prevent birds from fighting, perching, or nesting directly above the porcelain insulator strings of the conductors, ensuring the smooth operation of the line, reducing the occurrence of power outages, and demonstrating a significant effect in repelling and preventing bird damage without harming the birds' survival, thus realizing the principle of harmonious coexistence between humans and birds.

[0003] Traditional techniques use multiple splayed steel wires for fixing, effectively preventing birds from fighting, perching, or nesting directly above the porcelain insulator string. However, these techniques lack quick-release design, requiring the entire device to be disassembled for replacement or cleaning. Furthermore, the static installation method cannot actively generate dynamic interference, making it easy for birds to adapt. Summary of the Invention

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figs. 1-3 This utility model provides a technical solution:

[0022] A quick-release power line bird spike includes a U-shaped frame 1. A sleeve 2 is fixedly connected to the top of the U-shaped frame 1. An installation cylinder 3 is threadedly connected to the inside of the sleeve 2. A receiving groove 4 is opened inside the installation cylinder 3. A fixing post 5 is slidably connected inside the receiving groove 4. Multiple sets of bird spikes 6 are fixedly connected to the top of the fixing post 5. The bird spikes 6 radiate outward from the top of the fixing post 5, and are arranged in a fan-shaped array with a central angle of 120° to 160°. The bird spikes 6 are made of an elastic metal structure. An installation plate 7 is fixedly connected to the bottom of the inner side of the sleeve 2. A clamping device is fixedly connected to the top of the installation plate 7. The clamping plate 8 wraps around the fixing post 5. The U-shaped frame 1 is placed on the iron frame between the power grid lines and the iron frame is wrapped around it. At the same time, the bird spikes 6 are made of elastic metal material, which can swing to any extent to expand their bird-repelling range. When it is necessary to remove the bird spikes 6, the mounting cylinder 3 is rotated, and then the mounting cylinder 3 undergoes a threaded movement inside the sleeve 2, thereby realizing the spiral rise of the mounting cylinder 3, and then contacting the receiving groove 4 and the clamping plate 8 to fit together. When there is no thrust, the clamping plate 8 resets and releases the fixing of the fixing post 5.

[0023] Furthermore, in this embodiment, the clamping plates 8 are provided in multiple sets, and the multiple sets of clamping plates 8 are designed in a trumpet-shaped unfolding structure. Rubber particles are fixedly connected to the inner sidewall of the clamping plate 8 and the bottom end of the fixing post 5. When a pushing force is applied to the clamping plate 8, the top ends of the clamping plates 8 move closer to each other, and then the rubber particles of the clamping plate 8 and the rubber particles at the bottom end of the fixing post 5 rub against each other and adhere. While the friction increases, the adhesion force is improved.

[0024] Furthermore, in this embodiment, the clamping piece 8 is slidably connected to the interior of the receiving groove 4, which has a conical structure design. The top of the clamping piece 8 is fixedly connected to the extrusion block 9, which has an inclined structure design. The inner side wall of the sleeve 2 is provided with an internal thread groove, and the outer side wall of the mounting cylinder 3 is provided with an external thread groove. The internal thread groove and the external thread groove are adapted to each other. When the mounting cylinder 3 is rotated, the internal thread groove and the external thread groove mesh with each other, and then the mounting cylinder 3 spirals upward. Since the receiving groove 4 has a conical design, it is narrow at the top and wide at the bottom, and the lower half has a larger receiving area. Then it gradually moves away from the extrusion block 9. When the extrusion block 9 loses its thrust, the clamping piece 8 returns to its initial trumpet shape, releasing the fixation of the fixing post 5, thereby facilitating the removal of the fixing post 5 and completing the quick replacement of the bird spike 6.

[0025] Furthermore, in this embodiment, a collar 10 is fixedly connected to the outside of the sleeve 2, and a connecting ring 11 is provided outside the collar 10. A through groove 12 is formed between the connecting ring 11 and the collar 10. Multiple sets of balls 13 are rotatably connected inside the through groove 12. The connecting ring 11 has a hollow internal structure design, and a toothed ring 14 is fixedly connected inside the connecting ring 11. A gear 15 is meshed with the top of the toothed ring 14. One end of the gear 15 is fixedly connected to an extension rod 16. The extension rod 16 extends to the outside of the connecting ring 11 and is rotatably connected to the connecting ring 11. An interference plate 17 is fixedly connected to one end. Since the power grid is designed at a high position with sufficient airflow, when the airflow blows towards the interference plate 17, the extension rod 16 rotates, which in turn drives the gear 15 to mesh outside the gear ring 14. At the same time, the limiting position of the connecting ring 11 enables the interference plate 17 to rotate, thus eliminating any foothold for birds. When the interference plate 17 is vertical, its contact with the wind is at its maximum. The interference plate 17 is pushed to the outside of the connecting ring 11, and then the ball bearing 13 rolls in the through groove 12, enabling the interference plate 17 to revolve, further improving the bird deterrence efficiency.

[0026] Furthermore, in this embodiment, the surface of the interference plate 17 is coated with a reflective film, which is a PET aluminum-coated reflective film. The surface of the reflective film has a micron-level textured surface. The U-shaped frame 1 is internally threaded with a lead screw 18, and the bottom of the lead screw 18 is fixedly connected to a knob 19. Through the design of the reflective film, when sunlight shines on its exterior, it will reflect the light, thus interfering with the bird's vision. At the same time, the textured surface of the reflective film forms diffuse reflection when sunlight shines on it, and the light is reflected from various angles, causing the birds to move away from the overall device. By rotating the knob 19, the lead screw 18 is threaded inside the U-shaped frame 1, and then the lead screw 18 spirals upward inside it and fits against the iron frame, thus completing the fixation of the U-shaped frame 1.

[0027] In this embodiment, the specific implementation scenario is as follows: A U-shaped frame 1 is fitted onto an iron frame between power grid lines, and the iron frame is wrapped around it. By rotating the knob 19, the lead screw 18 is threaded inside the U-shaped frame 1, causing it to spiral upwards and fit against the iron frame, thus fixing the U-shaped frame 1. Simultaneously, the bird spikes 6 are made of elastic metal, allowing for arbitrary adjustment of their deployment to expand their bird-repelling range. Since the power grids are designed at high altitudes with sufficient airflow, when the airflow blows towards the interference plate 17, the extension rod 16 rotates, causing the gear 15 to mesh outside the gear ring 14. Simultaneously, the limiting position of the connecting ring 11 causes the interference plate 17 to rotate, eliminating any foothold for birds. When the interference plate 17 is vertical, its contact with the wind is at its maximum. The interference plate 17 is pushed to the outside of the connecting ring 11, and then the ball bearing 13 rolls in the through groove 12, realizing the revolution of the interference plate 17, further improving the bird-repelling efficiency, and then gradually moving away from the squeezing block 9. When the squeezing block 9 loses its thrust, the clamping piece 8 returns to its initial trumpet shape, releasing the fixation of the fixing post 5, so as to facilitate the removal of the fixing post 5 and complete the quick replacement of the bird spike 6. Through the design of the reflective film, when sunlight shines on its outside, it will reflect the light, thus interfering with the bird's vision. At the same time, the concave and convex texture designed on the surface of the reflective film forms diffuse reflection when sunlight shines on it, and the light is reflected from all angles, so the birds will directly stay away from the whole device.

[0028] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
