Description

Technical Field

[0001] This invention relates to the field of power distribution and transmission line technology, and in particular to an anti-nesting device for power distribution and transmission lines. Background Technology

[0002] In 10kV overhead power distribution line projects, double crossarms are widely used in various terrain scenarios such as rural fields, suburban woodlands, and mountain gullies due to their structural stability and strong load-bearing capacity. They are especially prevalent in areas with high bird population density, such as around orchards, on the edges of wetland reserves, and along urban greenbelts. However, the symmetrical structure of the double crossarm creates spacious and flat open areas on both sides, which perfectly suits the nesting habits of common birds such as magpies, crows, and sparrows. These birds often use twigs, dry grass, and cotton thread as basic materials, and may even collect metal debris such as wire, aluminum foil, and scrap wire ends to build nests between the crossarm and the line insulator, and at the connection between the end of the crossarm and the diagonal support arm.

[0003] Such nests pose multiple safety hazards during long-term operation. For example, dry nesting material is prone to becoming damp and conductive during thunderstorms, which can directly cause short circuits to the ground. Furthermore, if metal debris falls or comes into contact with the conductors, it can cause phase-to-phase short circuits, leading to line tripping. As the nests expand during the breeding season, they may also entangle the conductors and squeeze the insulators, reducing the insulation performance of the lines. In severe cases, they may even cause major accidents such as line burnout and tower tilting.

[0004] Currently, the mainstream bird deterrence method in the industry is still mainly based on single-barrier blocking. These barriers are mostly fixed-installation rigid plastic or metal plates, which not only have poor flexibility after installation and are difficult to adapt to different specifications of double crossbars, but also have obvious defects. In particular, the barriers can only block some birds taking off from the ground, and have limited protective effect on birds diving down from the air. In addition, there are still nests built around the barriers, making it difficult to fundamentally solve the safety hazards. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1 like Figure 1 - Figure 8 As shown, the present invention provides a bird behavior analysis-based anti-nesting device for power distribution and transmission lines, including a utility pole 1, a utility frame 2 and a triangular plate 5. The utility frame 2 is installed on the top of the utility pole 1, and a connecting mechanism 3 is installed on the top of the utility frame 2. The triangular plate 5 is inserted into the top of the connecting mechanism 3. A connecting rod 53 is fixedly connected to the top of the triangular plate 5, and a rotating shaft 52 is rotatably connected to the bottom of the connecting rod 53. Two T-shaped rods 7 are rotatably connected to the outer wall of the connecting rod 53. The T-shaped rods 7 are used to touch and vibrate the top of the wire frame 2. A wind-driven mechanism 6 is engaged at the bottom of the rotating shaft 52. The top of the wind-driven mechanism 6 is close to the bottom outer wall of the T-shaped rod 7. The wind drives the wind-driven mechanism 6, and the top of the wind-driven mechanism 6 intermittently pushes the T-shaped rod 7 to rotate. The T-shaped rod 7 intermittently knocks on the top of the wire frame 2.

[0032] Combination Figure 2 As shown, the power pole frame 2 includes a crossarm 21 and a diagonal support arm 22. The two crossarms 21 are set on the outer wall of the power pole 1 and are fixedly connected to each other. The diagonal support arm 22 is diagonally fixed between one end of the crossarm 21 and the bottom outer wall of the power pole 1. The two diagonal support arms 22 and the crossarm 21 form a triangular structure. The purpose of this arrangement is that the triangular support structure formed by the crossarm 21 and the diagonal support arm 22 has good stability and is used to support the line, the connecting mechanism 3, and the triangular plate 5.

[0033] Combination Figure 2 and Figure 3 As shown, the connecting mechanism 3 includes a slot block 31 and an L-shaped rod 32. The two L-shaped rods 32 are fixedly connected to the outer walls of the two sides of the slot block 31 respectively. Several elastic strips 33 are fixedly connected to the bottom outer wall of the L-shaped rod 32. The outer wall of the crossbeam 21 is provided with a mounting hole 210. The bottom of the L-shaped rod 32 is inserted into the mounting hole 210. The purpose of this arrangement is that the slot block 31 is inserted into the mounting hole 210 via the L-shaped rod 32. During the insertion process, the mounting hole 210 compresses and deforms the elastic strip 33, allowing the elastic strip 33 to pass through the diameter of the mounting hole 210. After the insertion is completed, the elastic strip 33 returns to its original position, thus limiting and fixing the slot block 31 and the L-shaped rod 32.

[0034] The elastic strip 33 is set in an arc shape, with the top of the arc structure protruding. The top protrusion is close to the lower surface of the crossbeam 21. This is to prevent the slot block 31 and the L-shaped rod 32 from loosening under the action of wind.

[0035] Combination Figure 3 As shown, a flexible aluminum sheet 4 is connected between the two L-shaped rods 32, and the flexible aluminum sheet 4 is set in a wavy shape; The purpose of this design is that the flexible aluminum sheet 4 is made of a lightweight and thin material structure so that when there is airflow at high altitude, the flexible aluminum sheet 4 will wave-like. The flexible aluminum sheet 4 is located above the crossbeam 21 to prevent birds from occupying the upper surface of the crossbeam 21. During the shaking process, a sound will be generated to drive away the birds.

[0036] Combination Figure 4 As shown, the triangle 5 is inserted between two slot blocks 31, and a handle 51 is fixedly connected to the top of the triangle 5. Several plate holes are opened on the outer wall of the triangle 5. The purpose of this design is to allow operators to use their hands to operate the triangular plate 5, with several holes for airflow to reduce lateral wind resistance.

[0037] Combination Figure 4 As shown, the slot block 31 has an installation groove inside, and a spring 8 is connected to the inner wall of the installation groove. One end of the spring 8 is fixedly connected to a ball 9. Grooves 50 are opened on the outer walls of both sides of the triangular plate 5, and the ball 9 is engaged with the groove 50. The purpose of this design is that when installing the triangle 5, you only need to hold the handle 51 with one hand and insert it vertically between the two slot blocks 31. When you insert it to the bottom, you will hear a click. The tension of the spring 8 pushes the ball 9 into the groove 50 for limiting. This is suitable for the connection of the triangle 5 to be stable and prevent it from loosening.

[0038] Combination Figure 5 As shown, a rubber ball is provided at the top of the T-shaped rod 7, an arc-shaped block is provided at the top of the T-shaped rod 7, and an elastic rod is provided at one end of the T-shaped rod 7 near the connecting rod 53. The rubber ball is provided to reduce damage to the crossbeam 21 when it is struck, the elastic rod is used to enhance the striking and vibration effect of the T-shaped rod 7, and the arc-shaped block is used to cooperate with the push rod 61.

[0039] Combination Figure 7 and Figure 8 As shown, the wind-driven mechanism 6 includes a push rod 61, a locking block 62, and wind cups 63. A slot 520 is provided on the bottom inner wall of the rotating shaft 52. Several wind cups 63 are fixedly connected to each other. A locking block 62 is fixedly connected to the middle of several wind cups 63. The wind cups 63 are locked onto the inner wall of the slot 520 by the locking block 62. The purpose of this design is that the wind cup 63 is connected to the slot 520 by the locking block 62, which is used to connect and drive the rotating shaft 52 and the wind cup 63. The high-altitude airflow blows the wind cup 63, and the wind cup 63 drives the rotating shaft 52 and the push rod 61 to rotate through the locking block 62. During the circular motion of the push rod 61, the push rod 61 pushes the arc-shaped block at the bottom of the T-shaped rod 7. Both the arc-shaped block and the push rod 61 are arc-shaped, and the wear is small during the mutual pushing process.

[0040] The push rod 61 is fixedly connected to the upper surface of the wind cup 63. The wind cup 63 and the arc block at the bottom of the T-shaped rod 7 push and engage. The T-shaped rod 7 rotates intermittently on the outer wall of the connecting rod 53. During the rotation, the rubber ball strikes and vibrates the crossbeam 21, further driving away birds. At the same time, the vibration generated can be transmitted to the triangle plate 5 to prevent the plate hole of the triangle plate 5 from being blocked and to maintain airflow.

[0041] Example 2: Based on Example 1, a hinge structure for the triangular plate 5 is provided; like Figure 9 - Figure 11 As shown, a solar panel 10 is fixedly connected to the outer wall of the triangular plate 5. The solar panel 10 integrates a controller and a battery. A photosensitive sensor is installed inside the controller. The bottom of the triangular plate 5 is set as a hinge structure. A torsion spring 11 is set at the connection of the hinge structure. In the windless state, the torsion spring 11 keeps the triangular plate 5 vertical. An irregularly shaped light strip is set on the outer wall of the triangular plate 5. The irregularly shaped light strip is electrically connected to the controller. The purpose of this design is that the bottom of the triangle 5 is set as a hinge structure. Under the action of the torsion spring 11, in the windless state, the torsion spring 11 keeps the triangle 5 vertically set. In the windy state, the wind blows the top of the triangle 5, causing the top of the triangle 5 to bend and rotate. This, combined with the hole in the triangle 5, is used to adapt to changes in wind resistance. The bending of the top structure of the triangle 5 reduces wind resistance. Then, when there is no wind, the torsion spring 11 resets the hinge structure of the triangle 5. During the reset process, rotational friction is generated at the connection of the hinge structure, which produces a slight vibration sound, further serving to repel birds. In this process, compared with the triangle 5 in Embodiment 1, in this embodiment, the hinge structure of the triangle 5 swings under the wind force. Its movement process plays a role in repelling birds in the process of adapting to wind resistance. In addition, it can be bent during carrying, reducing the space occupied during carrying and making it relatively convenient for high-altitude assembly. The solar panel 10 is positioned facing the sun. During the day, the solar panel 10 generates electricity through sunlight, which is then used to charge the battery via the controller. At night, the photosensitive sensor activates, switching the charging mode to the discharging mode. The controller then controls the battery to supply power to the irregularly shaped light strip, which illuminates the room at night and serves as a bird deterrent.

[0042] Working principle: When power workers are performing power work on the top of utility pole 1 and utility frame 2, the connecting mechanism 3, flexible aluminum sheet 4, triangular plate 5, wind-driven mechanism 6 and T-shaped pole 7 are designed to be lightweight, making it easier and less strenuous for workers to operate them. When installing it, simply insert the slot block 31 into the mounting hole 210 through the L-shaped rod 32. During the insertion process, the mounting hole 210 compresses and deforms the elastic strip 33, allowing the elastic strip 33 to pass through the hole diameter of the mounting hole 210. After the insertion is completed, the elastic strip 33 returns to its original position, thus limiting and fixing the slot block 31 and the L-shaped rod 32. Subsequently, when installing the triangle 5, simply hold the handle 51 with one hand and insert it vertically between the two slot blocks 31. When inserted to the bottom, a click will be heard. The tension of the spring 8 pushes the ball 9 into the groove 50 for limiting. This is suitable for the connection of the triangle 5 to be stable and prevent it from loosening. Finally, the wind cup 63 is connected to the slot 520 by the locking block 62, which is used to connect and drive the rotating shaft 52 and the wind cup 63. The high-altitude airflow blows the wind cup 63, and the wind cup 63 drives the rotating shaft 52 and the push rod 61 to rotate through the locking block 62. During the circular motion of the push rod 61, the push rod 61 pushes the arc-shaped block at the bottom of the T-shaped rod 7. The T-shaped rod 7 rotates intermittently back and forth on the outer wall of the connecting rod 53. During the rotation, the rubber ball knocks and vibrates the crossbeam 21, which further serves to drive away birds. At the same time, the vibration generated can be transmitted to the triangle 5 to prevent the plate hole of the triangle 5 from being blocked and to maintain airflow.

[0043] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
