Technical Field
[0001] This utility model relates to the field of power transmission and distribution line protection technology, specifically to a protection device for power transmission and distribution. Background Technology
[0002] With the rapid development of power systems, the safe operation of transmission and distribution lines faces numerous challenges, among which line faults caused by bird activity are becoming increasingly prominent. Birds perching, nesting, or foraging on transmission and distribution facilities can easily cause short circuits, power outages, and other accidents, seriously affecting the reliability of the power grid. Traditional bird deterrent devices have significant limitations in practical applications: Common bird deterrence techniques currently include the following categories: Static bird deterrent devices, such as reflective strips and bird spikes, primarily rely on visual intimidation to scare away birds. These devices are initially effective, but birds easily adapt, and their effectiveness typically declines significantly after 3-6 months. Furthermore, they are entirely dependent on external lighting conditions and become largely ineffective in cloudy or rainy weather or at night.
[0003] Wind-driven bird deterrents, such as windmill-style and rotating ball-type devices, utilize wind power to generate movement. Although these devices do not require external energy, their bird-repelling effect is greatly affected by wind speed, and they are almost ineffective in calm or light wind conditions. Furthermore, the simple rotational motion is a limited method of bird deterrence, making it easy for birds to adapt.
[0004] Electronic bird deterrent devices include ultrasonic and infrasonic electronic bird deterrents. While these devices are effective at deterring birds, they suffer from high energy consumption, frequent maintenance (batteries typically need replacing every 3-6 months), and high costs. In harsh outdoor environments, electronic components are susceptible to damage from lightning strikes and moisture, resulting in lower reliability.
[0005] The main shortcomings of existing technologies include: Bird deterrence methods are too simplistic, making it easy for birds to adapt. It has poor environmental adaptability, and its effectiveness is greatly reduced under conditions such as no wind or rain. It relies on external energy sources, resulting in high maintenance costs. It has a complex structure, insufficient reliability, and short service life.
[0006] To address the aforementioned problems, there is an urgent need to develop a novel bird-repelling protection device for power transmission and distribution that can achieve efficient and long-lasting bird-repelling effects under various environmental conditions, while also possessing advantages such as simple structure, maintenance-free operation, and low cost. This invention, through innovative mechanical structure design, perfectly solves many problems existing in the current technology. Utility Model Content
[0007] The purpose of this invention is to provide a protection device for power transmission and distribution to solve the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A protective device for power transmission and distribution includes a fixed frame installed on power transmission and distribution facilities and a bird-repelling assembly for preventing birds from damaging power transmission and distribution lines. The bird-repelling assembly includes a rotating cylinder connected by a rotating shaft and multiple counterweights. The rotating cylinder has an inner cylinder inside, and multiple partitions are provided between the inner cylinder and the rotating cylinder. The multiple partitions divide the area between the rotating cylinder and the inner cylinder into multiple activity spaces. Each counterweight corresponds to one activity space. The instantaneous force of a bird landing on the rotating cylinder will cause the rotating cylinder to deviate from its equilibrium state and enter an unbalanced state of rotation. At this time, the multiple counterweights will move within the activity spaces to maintain the rotation of the rotating cylinder until the kinetic energy is exhausted.
[0009] The above technical solution consists of a rotating cylinder, a polygonal inner cylinder, a partition, and a counterweight. When a bird lands, it triggers the rotation of the rotating cylinder. The counterweight maintains the motion due to inertia. The rotation is automatically started the moment the bird makes contact. No external energy is required. The inertia of the counterweight causes the rotating cylinder to rotate for a certain period of time, extending the deterrent time. It is a purely mechanical design and there are no electronic component failures.
[0010] A further improvement of the present invention is that the outside of the rotating drum is provided with a plurality of evenly arranged inclined plates.
[0011] In the above technical solution, a uniform inclined plate is added to the outer surface of the rotating cylinder. The inclined plate can assist the rotating cylinder in rotating under the force of wind or rain, and the inclined surface structure of the inclined plate makes it difficult for birds to stand stably.
[0012] A further improvement of the present invention is that the fixing frame includes two support plates, the support plates are provided with long grooves, the long grooves are provided with sliders, and the rotating shaft is rotatably connected between the two sliders through bearings, which facilitates installation.
[0013] In the above technical solution, a long groove and a slider are provided on the support plate, and the rotating shaft is connected to the slider through a bearing.
[0014] A further improvement of this utility model is that: the interior of the long groove is provided with multiple springs, and the multiple springs are respectively located on both sides of the slider.
[0015] The above technical solution includes a spring assembly on both sides of the slider inside the long groove, which can reduce the instantaneous impact force when birds land, keep the rotating drum in an up-and-down oscillating state for a certain period of time, and prolong the deterrent time to birds.
[0016] A further improvement of this utility model is that a power component is provided at the end of the rotating shaft.
[0017] The above technical solution involves adding a power component to the end of the shaft, which can maintain low-speed rotation even when not triggered by birds. The dual-drive mode of wind power and mechanical triggering improves reliability.
[0018] A further improvement of the present invention is that the power component includes a collar fixed on the rotating shaft, one end of the collar is provided with multiple support rods, and the end of the support rod is provided with a hollow hemisphere. When the hollow hemisphere is exposed to wind, it will drive the rotating shaft and the rotating cylinder on it to rotate through the support rods.
[0019] The above technical solution uses a power component consisting of a collar, a support rod, and a hollow hemisphere. The concave surface of the hollow hemisphere gathers wind, increasing the torque of the rotating drum, and can be used in windy environments.
[0020] A further improvement of this utility model is that: an airbag is provided in the long groove, and a whistle is provided on the airbag. When the slider moves up and down, the airbag will inhale or exhale air and make the whistle emit a sound.
[0021] The above technical solution involves installing an airbag and a whistle inside the long trough. The whistle emits a sound when the rotating drum is spinning, which can drive away birds.
[0022] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a protection device for power transmission and distribution. By setting up a bird deterrent assembly consisting of a rotating drum, a polygonal inner cylinder, a partition, and a counterweight, the rotating drum is triggered to rotate when a bird lands. The counterweight maintains the motion due to inertia, and the inclined plate can increase the rotation effect. It can be used in windy or rainy environments, and birds cannot stand stably on the rotating drum.
[0023] 2. This utility model provides a protection device for power transmission and distribution. By setting a power component, the power component is composed of a collar + support rod + hollow hemisphere. The concave surface of the hollow hemisphere gathers wind, so it can be used in windy environments. It can deter birds before they land on the rotating drum, making it impossible for the birds to stand firmly. The airbag and whistle can emit sound warnings.
[0024] This utility model provides a protection device for power transmission and distribution. By setting a rotating drum, the drum will rotate under external force, converting the kinetic energy of birds landing into continuous rotational motion, realizing a dual bird deterrence mode of "mechanical motion + sound wave deterrence". The bird deterrence efficiency is higher than that of a single mode. It can be used in windy or rainy environments, without consuming energy, and birds cannot stand stably on the rotating drum.

[0027] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figures 1-7 As shown, this utility model provides a protection device for power transmission and distribution, including a fixed frame 1 installed on power transmission and distribution facilities and a bird-repelling component for preventing birds from damaging power transmission and distribution lines. The bird-repelling component includes a rotating cylinder 2 connected by a rotating shaft 16 and multiple counterweights 3. The rotating cylinder 2 has an inner cylinder 4 inside, and multiple partitions 5 are provided between the inner cylinder 4 and the rotating cylinder 2. The multiple partitions 5 divide the area between the rotating cylinder 2 and the inner cylinder 4 into multiple activity spaces. Each counterweight 3 corresponds to one activity space. The instantaneous force of a bird landing on the rotating cylinder 2 will cause the rotating cylinder 2 to deviate from its balanced state and enter an unbalanced state of rotation. At this time, the multiple counterweights 3 will move within the activity space to maintain the rotation of the rotating cylinder 2 until the kinetic energy is exhausted.
[0028] In this embodiment, the fixed frame 1 is fixed to the power transmission and distribution facility by bolts, and the rotating drum 2 is installed on the fixed frame 1 by the rotating shaft 16. The rotating drum 2 is made of high-strength lightweight plastic and can rotate. The counterweight 3 is located inside the rotating drum 2. The inner cylinder 4 is fixed relative to the rotating drum 2. Multiple partitions 5 are integrally formed between the inner cylinder 4 and the rotating drum 2. Each counterweight 3 is located in its respective activity space and can move within its corresponding activity space. The counterweight 3 can be made of a small iron ball containing lead. The movement of the counterweight 3 can make the rotating drum 2 continue to rotate for a certain period of time, leaving no place for birds to stand, thereby achieving the purpose of repelling birds.
[0029] like Figures 1-7 As shown, in this embodiment, preferably, the outside of the rotating cylinder 2 is provided with a plurality of evenly arranged inclined plates 6, which are fixed on the rotating outer wall along the tangential direction. The rotating cylinder 2 can be rotated as long as a bird stands on the inclined plate 6.
[0030] like Figures 1-7 As shown, preferably, the fixing frame 1 includes two support plates 7, each support plate 7 has a long groove 8, and each long groove 8 has a slider 9. The rotating shaft 16 is rotatably connected between the two sliders 9 through a bearing. The long groove 8 is opened on the support plate 7, the slider 9 is slidably connected in the long groove 8, and the rotating shaft 16 is disposed through the two sliders 9. The rotating shaft 16 can be rotatably connected to the slider 9 through a bearing, thereby reducing the resistance to the rotation of the rotating cylinder 2.
[0031] Example 2 like Figures 1-7 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the interior of the long groove 8 is provided with a plurality of springs 10, and the plurality of springs 10 are respectively located on both sides of the slider 9.
[0032] In this embodiment, multiple springs 10 are arranged on both sides of the slider 9. When the rotating cylinder 2 is subjected to force, it will rise and fall, so that the rotating cylinder 2 is in an active state of both rotating and rising and falling, further preventing birds from landing on it.
[0033] Example 3 like Figures 1-7 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the end of the rotating shaft 16 is provided with a power component; the power component includes a collar 11 fixed on the rotating shaft 16, one end of the collar 11 is provided with a plurality of support rods 12, and the end of the support rod 12 is provided with a hollow hemisphere 13. When the hollow hemisphere 13 is exposed to wind, it will drive the rotating shaft 16 and the rotating cylinder 2 on it to rotate through the support rod 12.
[0034] In this embodiment, the power component enables the rotating drum 2 to rotate, preventing birds from standing on the rotating drum 2. The power component consists of a collar 11, a support rod 12, and a hollow hemisphere 13. There are multiple support rods 12 and hollow hemispheres 13, preferably six. The collar 11 is fixed to the rotating shaft 16. When the hollow hemisphere 13 is blown by the wind, it will drive the collar 11 and the rotating shaft 16 to rotate through the support rod 12. The rotation of the rotating shaft 16 can make the rotating drum 2 rotate continuously, preventing birds from standing on the rotating drum 2.
[0035] Example 4 like Figures 1-7As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an airbag 14 is provided in the long groove 8, and a whistle 15 is provided on the airbag 14. When the slider 9 rises and falls, the airbag 14 will inhale or exhale air and make the whistle 15 emit a sound.
[0036] In this embodiment, the airbag 14 can be purchased directly from the market. The airbag 14 is located on both sides of the slider 9. The whistle 15 can be a commonly used whistle reed. The whistle 15 is inserted into the air inlet and outlet of the airbag 14. When the airbag 14 inhales or exhales, the airflow passes through the whistle 15 and makes a sound to drive the birds away.
[0037] The working principle of this power transmission and distribution protection device will be explained in detail below.
[0038] like Figures 1-7 As shown, before use, this device is installed on the power transmission and distribution facilities. When a bird stands on the inclined plate 6 on the rotating drum 2, it will generate an instantaneous force on the rotation. This instantaneous force can make the rotating drum 2 rotate at a certain angle. At this time, the multiple counterweights 3 inside the rotating drum 2 will go from a balanced state to an unbalanced state, which will cause the rotating drum 2 to continue to rotate. During this period, the bird cannot stand on the rotating drum 2. After the kinetic energy of the rotating drum 2 is consumed, it will return to a balanced state. When the bird stands on the rotating drum 2 again, the rotating drum 2 will continue to rotate.
[0039] When the hollow hemisphere 13 is blown by the wind, the hollow hemisphere 13 will drive the rotating cylinder 2 on the rotating shaft 16 to rotate through the support rod 12 and the collar 11, providing power for the rotation of the rotating cylinder 2; when the rotating cylinder 2 is in rainy weather, rainwater will fall between the inclined plate 6 and the outer wall of the rotating cylinder 2, providing power for the rotation of the rotating cylinder 2.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
