Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically a bird deterrent device for power transmission lines. Background Technology

[0002] The wind-powered reflective bird deterrent is a new type of bird deterrent product. It is easy to install, widely adaptable, and maintenance-free. It is mainly suitable for power system transmission lines, outdoor switch sites in substations, and other occasions where birds need to be driven away. Based on the characteristics of birds that are afraid of light and color, especially flashing lights, this product drives them away from poles and towers to prevent them from nesting, thereby eliminating bird damage and ensuring the safe operation of power.

[0003] In the field of electrical engineering, overhead transmission lines, as the core carriers for cross-regional transmission of electrical energy, are directly related to the reliability of the power system and the normal order of social production and life due to their safe and stable operation. However, the safety hazards brought by bird activity have always been one of the important factors threatening the operation of transmission lines. When birds nest on critical parts such as crossarms and insulator strings of towers, the long nesting materials they use, such as branches, wires, and dry grass, are very likely to hang between the conductors and towers, which can significantly reduce the air gap or even short-circuit, causing phase-to-phase short circuits or discharges to ground, and thus causing the transmission line to trip. To solve this problem, bird deterrents are widely used in the industry for active protection. Among them, wind-powered reflective bird deterrents are commonly used bird deterrent devices. However, in the existing technology, the reflectors of wind-powered reflective bird deterrents are mostly arranged in a single vertical plane, and their reflection angle is concentrated in the horizontal and low-altitude areas. When birds approach from above the tower, the reflected light cannot cover this area, and the birds have difficulty perceiving the warning signal. They may still continue to approach the tower to nest, thus affecting the success rate of bird deterrence.

[0004] Therefore, this utility model provides a bird deterrent device for electrical engineering transmission lines to solve the above-mentioned problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a bird deterrent device for power transmission lines in electrical engineering, such as... Figure 1-4 As shown, this type of bird deterrent device for power transmission lines includes a base 1 and an adjustable bird deterrent structure. The bottom of the base 1 is provided with mounting holes, which are fixed to the transmission line tower by bolts in the mounting holes. The installation position can be selected close to the crossarm or insulator string according to the structural characteristics of the tower, ensuring that the bird deterrent range accurately covers the areas where birds are likely to nest. The adjustable bird deterrent structure is set on the top of the base 1. Its core innovation lies in breaking through the limitation of the traditional single vertical plane arrangement of reflectors through a multi-dimensional adjustment mechanism, so as to realize the flexible adjustment of the reflective light area. Specifically, the adjustable bird deterrent structure includes a fixed rod 2 fixedly installed on the top of the base 1. The outer surface of the fixed rod 2 is rotatably connected to the rotating shaft 3 via bearings, allowing the rotating shaft 3 to rotate around the fixed rod 2 with the natural wind, ensuring that the reflective components can dynamically align with birds coming from different directions. Three sets of fixed shafts 4 are fixedly fixed on the outer surface of the rotating shaft 3, evenly distributed at 120°. Each set of fixed shafts 4 has a telescopic movable rod 5 inside. The reflective distance can be adjusted by extending and retracting the movable rod 5. When birds often approach from a distance, the movable rod 5 can be extended to increase the warning range. When the space around the pole is narrow, the movable rod 5 can be shortened to avoid interference with other components. The windmill-shaped mirror bowl 6 fixed to the outer end of the movable rod 5 has a first reflector 7 embedded in it. Its arc-shaped structure can reflect light to the horizontal and low-altitude areas, forming basic protection for the area already covered by traditional bird deterrents. The key improvement lies in the movable part 8 on the outer surface of the movable rod 5. The second reflector 9 embedded in it can be adjusted in the following way: a rubber ring 11 is set between the movable part 8 and the knob 10. When the knob 10 is rotated, the rubber ring 11 is squeezed to generate friction and fix the movable part 8. The three sets of second reflectors 9 can be adjusted independently. The operator can rotate the three sets of movable parts 8 around the corresponding movable rod 5 according to the three-dimensional distribution characteristics of bird activities on site, so that the reflective area forms a gradient coverage in the vertical direction, from low altitude to obliquely upward, with no blind spots, significantly expanding the warning range. Specifically, multiple slots 12 on the outer surface of the movable rod 5 cooperate with the threaded rod 13 on the outer side of the fixed shaft 4. After adjusting the extension length of the movable rod 5, it can be locked by the thread to prevent displacement under wind force. A photovoltaic panel 15 is installed on the support frame 14 on the outer surface of the fixed rod 2. It forms an independent power supply system with the internal battery and controller. During the day, the photovoltaic panel 15 converts solar energy into electrical energy and stores it in the battery to ensure that the strobe light 16 at the top can still work normally even at night or in rainy weather. The strobe light 16 flashes under the action of the controller, which is specifically designed to enhance the warning effect for birds at night. When the natural light disappears and the reflector fails, the strong light of the strobe light can penetrate the darkness to provide continuous visual stimulation to birds coming from above and around, achieving uninterrupted protection day and night and making up for the limitations of the single reflector mechanism at night. In practical applications, protection can be achieved through triple adjustment based on the bird activity characteristics of different towers. The extension length of the movable rod 5 can be adjusted by the cooperation of the threaded rod 13 and the slot 12 to adapt to the protection needs of different tower heights. The three sets of movable parts 8 can be rotated independently and the knob 10 can be locked to make the second reflector 9 form a differentiated angle combination, accurately covering the multi-dimensional paths where birds often appear. By utilizing the wind-following rotation characteristics of the rotating shaft 3, it is ensured that the reflection and flashing can dynamically respond with the direction of bird movement. This device effectively solves the problems of insufficient warning of birds coming from diagonally above and lack of protection at night in traditional wind-powered reflective bird deterrents by expanding the reflective coverage angle, enhancing the diversity of warning modes and the day and night collaborative working mechanism. It significantly reduces the probability of birds nesting in key parts of the tower and provides a reliable guarantee for the safe operation of transmission lines.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
