Description

Technical Field

[0001] This utility model relates to the field of lightning arrester technology, specifically to a bird-proof outdoor lightning arrester. Background Technology

[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltages caused by lightning strikes and to limit the duration and amplitude of follow current. Surge arresters are sometimes also called overvoltage protectors or overvoltage limiters. They are suitable for overvoltage protection of transformers, transmission lines, distribution panels, switchgear, power metering boxes, vacuum switches, parallel compensation capacitors, rotating electrical machines, and semiconductor devices. Surge arresters are commonly used in outdoor power grids.

[0003] Patent document CN215772489U discloses a simple and convenient 35kV outdoor AC explosion-proof surge arrester, including a surge arrester body and a base located at the bottom of the surge arrester body. The top of the base has a fixing hole, and symmetrically arranged through holes are formed on both sides of the fixing hole. A horizontally arranged movable block is provided within each through hole. A fixing tooth block is provided on one side of the movable block, located within the fixing hole. The bottom of the surge arrester body has a fixing post that matches the fixing hole. Beneficial effects: Through the cooperative design of the surge arrester body and the base, the engagement of the fixing tooth block and the tooth plate facilitates installation and disassembly, effectively reducing the construction difficulty of the surge arrester, improving construction efficiency, and reducing manufacturing costs. It facilitates the installation of the surge arrester body. The cooperative design of the limiting groove and the limiting block provides stability to the surge arrester body, ensuring that the surge arrester body is not prone to shaking in extreme weather conditions. However, the existing technology still has shortcomings: Current surge arresters are generally installed in high places in outdoor environments. Outdoor environments are full of birds, which can easily attract birds to stop and rest on the surge arresters. Bird droppings can also corrode the surge arresters, affecting their conductivity and thus reducing their effectiveness in lightning protection.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a bird-proof outdoor lightning arrester.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a bird-proof outdoor surge arrester, including a base, a surge arrester body on the top of the base, the surge arrester body including a fixed shaft installed on the top of the base, and a plurality of ceramic discs evenly spaced on the fixed shaft, characterized in that: A rotating structure is provided on the outside of the surge arrester body; A bird-repelling structure is located at both ends of the top of the base.

[0007] Furthermore, the rotating structure includes a rotating ring sleeved at both ends of a fixed shaft. The rotating ring is rotatably connected to the fixed shaft. A horizontal bar is fixedly connected to the outer wall of the rotating ring. There are multiple horizontal bars distributed circumferentially around the rotating ring. A vertical bar is fixedly connected between the ends of two horizontal bars away from the rotating ring. A connecting rod is fixedly connected to the outer wall of the vertical bar away from the rotating ring. A rubber ball is fixedly connected to one end of the connecting rod.

[0008] Furthermore, a wind cup is fixedly connected to the end of the crossbar away from the rotating ring, and the wind cup is located at the top of the fixed shaft.

[0009] Furthermore, the bird-repelling structure includes brackets fixedly connected to both ends of the top of the base. Fixed seats are fixedly connected to the inner wall of the brackets. There are multiple fixed seats arranged at equal intervals. A metal plate is rotatably connected to the fixed seat. Springs are fixedly connected to both ends of the outer wall of the metal plate. One end of the spring is fixedly connected to the inner wall of the bracket. Bird-repelling spikes are fixedly connected to the top of the bracket. There are multiple bird-repelling spikes arranged at equal intervals.

[0010] Furthermore, reflectors are fixedly installed on both ends of the outer wall of the vertical rod.

[0011] The advantages of this invention compared to existing technologies are as follows: Through the design of the rotating and bird-repelling structures, multiple wind cups rotate under the force of the wind, causing the rotating ring to rotate around the lightning arrester body. The rotating ring drives the horizontal and vertical rods to rotate, and the vertical rods drive the reflectors to rotate, dynamically reflecting sunlight in different directions, thus interfering with birds' vision and effectively driving them away. Simultaneously, the vertical rods drive the connecting rods to rotate, causing the rubber ball at the end of the connecting rod to strike the metal plate. Under the action of the spring, the struck metal plate emits a sound, startling surrounding birds. This sound further drives away birds attempting to approach the lightning arrester body, further improving the bird-repelling effect. It effectively prevents birds from approaching the lightning arrester body, avoiding bird droppings on the lightning rod, and also prevents birds from landing or nesting on the lightning arrester body, ensuring the normal use and power supply safety of the lightning arrester body, increasing the service life of the lightning arrester, and demonstrating good practicality.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0022] like Figures 1 to 7As shown, this embodiment proposes a bird-proof outdoor surge arrester, including a base 1, with a surge arrester body 2 on the top of the base 1. The surge arrester body 2 includes a fixed shaft 21 installed on the top of the base 1, and multiple ceramic discs 22 are evenly spaced on the fixed shaft 21. The surge arrester body 2 is existing technology and will not be described in detail here.

[0023] The surge arrester body 2 is provided with a rotating structure 3 on the outside. The rotating structure 3 includes a rotating ring 31 sleeved on both ends of the fixed shaft 21. The rotating ring 31 is rotatably connected to the fixed shaft 21. The rotating ring 31 is rotatably connected to the fixed shaft 21 through a sealed bearing with good sealing performance. The bearings mentioned above are all existing technologies, so their technical principles will not be described in detail here.

[0024] A horizontal bar 32 is fixedly connected to the outer wall of the rotating ring 31. There are multiple horizontal bars 32, which are distributed in a circle around the rotating ring 31. A vertical bar 33 is fixedly connected between the ends of two horizontal bars 32 away from the rotating ring 31. A connecting rod 34 is fixedly connected to the outer wall of the vertical bar 33 away from the rotating ring 31. A rubber ball 35 is fixedly connected to one end of the connecting rod 34. A wind cup 36 is fixedly connected to the end of the horizontal bar 32 away from the rotating ring 31. The wind cup 36 is located at the top of the fixed shaft 21. The wind cup 36 is set in a bowl shape to facilitate the wind gathering effect. A flute tube is provided inside the wind cup 36 so that when the wind cup 36 rotates, airflow passes through the flute tube and emits a flute sound to disturb and drive away birds.

[0025] Bird-repelling structures 4 are provided at both ends of the top of the base 1. The bird-repelling structures 4 include brackets 41 fixedly connected to both ends of the top of the base 1. The brackets 41 are U-shaped. Fixed seats 42 are fixedly connected to the inner wall of the brackets 41. There are multiple fixed seats 42 and they are evenly spaced. A metal plate 43 is rotatably connected to the fixed seat 42. Springs 44 are fixedly connected to both ends of the outer wall of the metal plate 43. One end of the spring 44 is fixedly connected to the inner wall of the bracket 41. The setting of the spring 44 makes it easy to reset the metal plate 43 so that the metal plate 43 can be used repeatedly. Bird-repelling spikes 45 are fixedly connected to the top of the brackets 41. There are multiple bird-repelling spikes 45 and they are evenly spaced. The setting of the bird-repelling spikes 45 can further reduce the probability of birds landing on the lightning arrester body 2 and further improve the protection effect of the lightning arrester body 2.

[0026] Reflectors 46 are fixedly installed on both ends of the outer wall of the vertical pole 33. By rotating the reflectors 46, sunlight can be dynamically reflected in different directions. The reflectors 46 constantly change direction, reflecting sunlight from different directions to shine into the eyes of birds. Birds' eyes are extremely sensitive, and they are easily startled and fly away when their eyes are shone, thus achieving the purpose of repelling birds.

[0027] In practical application, when the wind blows, multiple wind cups 36 rotate under the force of the wind, which in turn drives the rotating ring 31 to rotate around the arrester body 2. The rotating ring 31 drives the horizontal bar 32 and the vertical bar 33 to rotate, and the vertical bar 33 drives the reflector 46 to rotate. The rotating reflector 46 can dynamically reflect sunlight in different directions, thereby interfering with the vision of birds and effectively driving them away. At the same time, the rotation of the vertical bar 33 will drive the connecting rod 34 to rotate, so that the rubber ball 35 at the end of the connecting rod 34 will strike the metal plate 43. When the metal plate 43 is struck by the spring 44, it vibrates violently, causing it to make a sound that startles nearby birds. This sound drives away birds that try to approach the surge arrester body 2, further improving the bird-repelling effect. It effectively prevents birds from approaching the surge arrester body 2, avoids birds dropping their droppings on the lightning rod, and prevents birds from landing or nesting on the surge arrester body 2. This ensures the normal use and power supply safety of the surge arrester body 2, increases the service life of the surge arrester, and has good practicality.
