Description

Technical Field

[0001] This utility model relates to the field of line protection technology, and in particular to a bird cover for overhead transmission lines with self-cleaning function. Background Technology

[0002] In the operation and maintenance of overhead transmission lines, bird shields are crucial facilities to prevent birds from nesting and roosting on towers, and to avoid bird droppings contaminating insulators and causing short-circuit faults. However, bird shields exposed to the outdoors for extended periods face significant cleaning challenges. Dust, dirt, bird droppings, and other impurities from the natural environment continuously adhere to the surface of the bird shields, affecting not only their appearance but, more importantly, clogging the ventilation holes. This prevents effective heat dissipation, leading to increased line temperatures. Excessive temperatures accelerate the aging of the transmission line insulation, potentially causing short circuits, fires, and other serious accidents, threatening the safe and stable operation of the power grid. Traditional cleaning methods rely on manual climbing of towers, which is not only labor-intensive and inefficient but also carries safety risks such as falls and electric shocks. Furthermore, due to the wide distribution of transmission lines, manual cleaning is difficult to achieve in a timely and comprehensive manner, failing to fundamentally solve the heat dissipation problem caused by accumulated dirt on the bird shields. The inventors believe that the following defects often exist: after long-term use, a large amount of dust and impurities adhere to the arc surface of the bird cover body, which reduces the heat dissipation function of the bird cover body, thereby causing the line to overheat and short-circuit spontaneous combustion. Therefore, in order to solve the above problems, an overhead transmission line bird cover with self-cleaning function is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing bird cover technology, such as reduced heat dissipation of the bird cover body leading to overheating, short circuits, and spontaneous combustion of the line. This invention proposes a bird cover for overhead transmission lines with self-cleaning function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a bird-proof cover for overhead transmission lines with self-cleaning function, comprising a bird-proof cover body, two rotating rings rotatably connected to the arc surface of the bird-proof cover body, four connecting plates fixedly connected to the arc surface of each of the two rotating rings, the eight connecting plates being grouped in pairs, a support plate fixedly connected to one side of each group of connecting plates, a sliding rod slidably inserted inside the support plate, a cleaning plate fixedly connected to one end of the sliding rod, a cleaning pad slidably connected to one side of the cleaning plate, and a circular plate fixedly connected to one end of the sliding rod.

[0005] The aforementioned components achieve the following effect: they automatically clean the bird shield body, preventing a large amount of dust and impurities from adhering to the arc surface of the bird shield body after prolonged use, thus reducing the heat dissipation function of the bird shield body and causing the circuit to overheat and short circuit, thereby improving the practicality of the device.

[0006] Preferably, a round rod is fixedly connected to the upper surface of the round plate, and an air receiving plate is fixedly connected to the arc surface of the round rod.

[0007] The effect achieved by the above components is to increase the efficiency of receiving wind energy from high altitudes, so as to convert more wind energy into the kinetic energy of the support plate rotation, thereby improving the rotation efficiency of the rotating ring on the bird cover body.

[0008] Preferably, a first spring is fitted onto the arc surface of the slide rod, and the two ends of the first spring are fixedly connected to the circular plate and the support plate, respectively.

[0009] The effect achieved by the above components is as follows: the elastic force of the first spring drives the cleaning plate closer to the bird cover body, so that the cleaning pad is tightly attached to the arc surface of the bird cover body, thereby improving the cleaning ability of the cleaning pad.

[0010] Preferably, two fixing plates are fixedly connected to one side of the cleaning pad, the surface of the fixing plates is slidably connected to the cleaning plate, two square plates are fixedly connected to the surface of the cleaning plate, a fixing rod is fixedly connected to the surface of the square plates, an operating plate is slidably connected to the arc surface of the fixing rod, an insertion rod is fixedly connected to one side of the operating plate, and an insertion hole is opened on the surface of the fixing plate.

[0011] The above components achieve the following effect: they secure the cleaning pad and the cleaning board, while also facilitating the replacement of the cleaning pad later.

[0012] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the insertion hole of the fixing plate.

[0013] The effect achieved by the above components is to limit the maximum sliding distance of the control panel on the arc surface of the fixed rod, thus preventing the control panel from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.

[0014] Preferably, a second spring is fitted onto the arc surface of the fixing rod, and the two ends of the second spring are fixedly connected to the operating plate and the square plate, respectively.

[0015] The aforementioned components achieve the following effects: they automatically guide the insertion rod into the socket of the fixing plate, while also improving the stability of the insertion rod when it is positioned relative to the fixing plate.

[0016] Preferably, a rubber ring is fixedly connected to the surface of the control panel, and the rubber ring is slidably connected to the arc surface of the fixing rod.

[0017] The effect achieved by the above components is that the elasticity of the rubber ring wraps around the arc surface of the fixed rod, thereby slowing down the sliding speed of the operating plate on the arc surface of the fixed rod, reducing the impact of external shaking on the operating plate, and playing a damping role.

[0018] In summary, the beneficial effects of this utility model are as follows: This invention achieves the effect of automatically cleaning the bird shield body, avoiding the accumulation of a large amount of dust and impurities on the arc surface of the bird shield body after prolonged use, which would reduce the heat dissipation function of the bird shield body and cause the circuit to overheat and short circuit, thus improving the practicality of the device.

[0021] Reference Figure 1-5As shown, this utility model provides a technical solution: a bird-proof cover for overhead transmission lines with self-cleaning function, comprising a bird-proof cover body 1. Two rotating rings 2 are rotatably connected to the arc surface of the bird-proof cover body 1. Four connecting plates 3 are fixedly connected to the arc surface of each of the two rotating rings 2. The eight connecting plates 3 are arranged in pairs. A support plate 4 is fixedly connected to one side of each pair of connecting plates 3. A sliding rod 5 is slidably inserted into the support plate 4. A cleaning plate 6 is fixedly connected to one end of the sliding rod 5. A cleaning pad 7 is slidably connected to one side of the cleaning plate 6. A circular plate 8 is fixedly connected to one end of the sliding rod 5. When the bird-proof cover body 1 is used, it is placed on the line. When there is wind at a high altitude, the support plate 4 rotates, causing the rotating rings 2 to rotate on the arc surface of the bird-proof cover body 1. Simultaneously, the support plate 4 drives the cleaning pad 7 to rotate on the arc surface of the bird cover body 1, thereby achieving the effect of automatic cleaning of the bird cover body 1. This avoids the accumulation of dust and impurities on the arc surface of the bird cover body 1 after prolonged use, which would reduce the heat dissipation function of the bird cover body 1 and cause overheating and short circuits. This improves the practicality of the device. A round rod 9 is fixedly connected to the upper surface of the round plate 8, and a wind receiving plate 10 is fixedly connected to the arc surface of the round rod 9. This increases the efficiency of receiving wind energy from high altitudes, so as to convert more wind energy into the kinetic energy of the support plate 4 rotation, thereby improving the rotation efficiency of the rotating ring 2 on the bird cover body 1. A first spring 11 is sleeved on the arc surface of the slide rod 5, and the two ends of the first spring 11 are... The cleaning pad 7 is fixedly connected to the circular plate 8 and the support plate 4. The elastic force of the first spring 11 drives the cleaning plate 6 closer to the bird cover body 1, so that the cleaning pad 7 is tightly attached to the arc surface of the bird cover body 1, thereby improving the cleaning ability of the cleaning pad 7. Two fixing plates 12 are fixedly connected to one side of the cleaning pad 7. The surface of the fixing plate 12 is slidably connected to the cleaning plate 6. Two square plates 13 are fixedly connected to the surface of the cleaning plate 6. Fixing rods 14 are fixedly connected to the surface of the square plates 13. An operating plate 15 is slidably connected to the arc surface of the fixing rods 14. An insertion rod 16 is fixedly connected to one side of the operating plate 15. Insertion holes are opened on the surface of the fixing plate 12 to achieve the effect of fixing the cleaning pad 7 to the cleaning plate 6, and at the same time facilitate the subsequent replacement of the cleaning pad 7. The fixing rod 14 A limiting plate 17 is fixedly connected to one end of the operating plate 16. The size of the insertion rod 16 is adapted to the size of the insertion hole of the fixing plate 12, which achieves the effect of limiting the maximum sliding distance of the operating plate 15 on the arc surface of the fixing rod 14. This avoids the situation where the operating plate 15 detaches from the arc surface of the fixing rod 14 due to excessive pulling force when the operator pulls it. A second spring 18 is sleeved on the arc surface of the fixing rod 14. The two ends of the second spring 18 are fixedly connected to the operating plate 15 and the square plate 13, respectively, which achieves the effect of automatically bringing the insertion rod 16 into the insertion hole of the fixing plate 12, and at the same time improves the stability of the insertion rod 16 when limiting the fixing plate 12. A rubber ring 19 is fixedly connected to the surface of the operating plate 15, and the rubber ring 19 is slidably connected to the arc surface of the fixing rod 14.The elasticity of the rubber ring 19 wraps around the arc surface of the fixed rod 14, thereby slowing down the sliding speed of the operating plate 15 on the arc surface of the fixed rod 14, reducing the impact of external shaking on the operating plate 15, and achieving a damping effect.

[0022] Working principle: During use, the bird cover body 1 is placed on the power transmission line. The wind energy at a high altitude drives the wind receiving plate 10 to rotate. The wind receiving plate 10 drives the circular plate 8 to rotate via the circular rod 9, which in turn causes the sliding rod 5 and the support plate 4 to move synchronously. The support plate 4 drives the rotating ring 2 to rotate on the arc surface of the bird cover body 1. At this time, the cleaning pad 7 slides around the surface of the bird cover body 1 with the support plate 4, realizing automatic cleaning. The elastic force of the first spring 11 pushes the circular plate 8, so that the cleaning plate 6 drives the cleaning pad 7 to always be in close contact with the surface of the bird cover body 1, ensuring the cleaning effect. When it is necessary to replace the cleaning pad 7, the operating plate 15 is pulled. The operating plate 15 overcomes the elastic force of the second spring 18 and slides on the fixed rod 14, driving the insertion rod 16 from the fixed plate 12. Pull the old cleaning pad 7 out of the socket to release its restriction, and then remove it. When installing the new cleaning pad 7, align the fixing plate 12 with the cleaning plate 6, release the operating plate 15, and the second spring 18 releases its rebound force to automatically insert the plug 16 into the socket of the fixing plate 12 to complete the fixing. During this process, the limiting plate 17 restricts the sliding distance of the operating plate 15, and the rubber ring 19 wraps around the fixing rod 14 with elasticity to slow down the sliding speed of the operating plate 15 and prevent external shaking from affecting its stability. The device uses wind power to drive the cleaning structure to operate automatically, continuously removing dust and impurities from the surface of the bird cover body 1, preventing poor heat dissipation caused by dust accumulation and circuit failure. At the same time, the convenient cleaning pad 7 replacement mechanism improves maintenance efficiency.
