Description

Technical Field

[0001] This utility model relates to the field of power distribution engineering technology, and more specifically, to a lightning protection and bird deterrent device for power distribution network engineering. Background Technology

[0002] In power distribution network engineering, shorter routes such as urban and rural distribution branches, internal distribution lines in residential areas, and short-distance interconnection lines in industrial parks are key links in ensuring the reliability of power supply to end users. These lines often pass through residential areas, green belts, or farmland. A significant characteristic of these areas is the high density of bird activity, and their droppings and nesting materials (such as branches and wires) can easily cause phase-to-phase short circuits and single-phase grounding faults.

[0003] Existing stand-alone bird deterrent devices, such as ultrasonic bird deterrents, are mostly designed for long-distance trunk lines, requiring a fixed spacing of 1-2 poles / units to achieve full line coverage. However, for shorter lines with fewer poles and more dispersed sections, this arrangement can easily lead to two problems: either overlapping coverage areas of the bird deterrent devices result in redundant equipment configuration, increasing procurement costs; or the number of devices is reduced to control costs, creating bird-deterrent blind spots. Therefore, we propose a lightning protection bird deterrent device for power distribution network engineering. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a lightning protection and bird deterrence device for power distribution network engineering, so as to solve the technical problem that the bird deterrence equipment in the current power distribution engineering is not optimized for the characteristics of short-route scenarios.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lightning protection and bird deterrence device for power distribution network engineering, comprising two port bushings and line disturbance structures connected thereto, with a disturbance line connecting the two line disturbance structures. Each line disturbance structure includes a port active bearing and a port driven bearing connected to the port bushings. The port active bearing and the port driven bearing are provided with several extension rods. The port active bearing and the port driven bearing are respectively connected to a port active plate and a port driven plate through the extension rods. A deflector plate is connected to the port active plate and is connected to the disturbance line. A baffle plate is provided on the side of the port active bearing and the port driven bearing opposite to the extension rods. A drop plate is provided on the side of the baffle plate away from the port active bearing and the port driven bearing.

[0006] Preferably, the port bushing is provided with a positioning ring on the outside, and the positioning ring is provided with a lightning protection plate for connecting to the power grid grounding device. The port bushing is provided with a through hole in the middle for the transmission line to pass through, and the diameter of the through hole is larger than the diameter of the transmission line.

[0007] Preferably, a linkage rod is provided between the port active bearing and the port driven bearing, and the extension rod and the top connecting structure are located above the relative position of the spoiler when no external force is applied. The extension rod is detachably connected to the port active bearing and the port driven bearing.

[0008] Preferably, the end of the dial plate near the port active plate is provided with a gravity adapter block that is rotatably connected, the gravity adapter block being snapped into the port active plate, and the side of the dial plate near the disturbance line is provided with a connector block for fixing the disturbance line.

[0009] Preferably, the port driven plate is provided with a groove that cooperates with the dial plate, the dial plate is connected to the disturbance line based on the wiring block, and the disturbance line is in a drooping state in a fixed state.

[0010] Preferably, the bottom of the spoiler is connected to the drop plate, the outer wall of the spoiler is recessed inward, and the drop plate has an elliptical structure with a solid metal interior.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a line disturbance structure, fixed based on a port sleeve. Two sets of line disturbance structures connect the disturbance line, ensuring real-time disturbance of the transport line within the connection range. Through the influence of the port active bearing, bottom spoiler, and drop plate, the line actively sways left and right due to its own weight and the external environment. When birds are located on the transmission line within this range, the disturbance of the disturbance line can deter them. If birds stand directly on the disturbance line, the overall weight of the line increases, causing the port active bearing and port driven bearing to rotate the entire line. When the line rotates to the bottom of the port sleeve, the deflector separates from the port driven plate, performing a secondary swing to deter birds. When there are no birds on the disturbance line, the drop plate returns to its original position, rotating the line back to the top for the next bird-deterrent disturbance operation. This method eliminates the need for manual bird deterrence and is suitable for bird deterrence operations on shorter lines in power grid engineering, reducing the poor effectiveness of bird deterrence on short lines. It solves the technical problem of current power distribution engineering not optimizing bird deterrence equipment for the characteristics of shorter routes.

[0012] 2. This utility model also uses a port sleeve and its connected positioning ring, which are fixed to the pole by a lightning protection plate at the bottom of the positioning ring. Since the bottom of the pole is inserted into the ground, grounding is achieved. This allows for both equipment fixation and lightning protection, ensuring that the line disturbance structure on the port sleeve will not affect normal lightning protection operations while repelling birds from the transmission line. This reduces incompatibility, facilitates real-time bird repelling operations, requires no additional power, is low-cost, and is convenient for short-line bird repelling, thus solving the adaptability defects of existing bird repelling operations.

Detailed Implementation

[0015] like Figures 1 to 5 As shown, this utility model relates to a lightning protection and bird deterrent device for power distribution network engineering, including two port bushings 110 and a line disturbance structure 200 connected thereto. A disturbance line 263 is connected between the two line disturbance structures 200. The line disturbance structure 200 includes a port active bearing 210 and a port driven bearing 230 connected to the port bushings 110. Several extension rods 240 are provided on the port active bearing 210 and the port driven bearing 230. The port active bearing 210 and the port driven bearing 230 are respectively connected to a port active plate 250 and a port driven plate 270 through the extension rods 240. A lever plate 260 is connected to the port active plate 250 and is connected to the disturbance line 263. A baffle plate 280 is provided on the side of the port active bearing 210 and the port driven bearing 230 opposite to the extension rods 240. A drop plate 290 is provided on the side of the baffle plate 280 away from the port active bearing 210 and the port driven bearing 230.

[0016] This invention utilizes a line disturbance structure 200, fixed to the port sleeve 110. Two sets of line disturbance structures 200 are connected via a disturbance line 263, ensuring real-time disturbance of the transport line within the connection range. Through the influence of the port active bearings 210 and 23, the bottom spoilers 280 and drop plates 290, under their own weight and the external environment, actively sway left and right. When birds are located on the power line within this range, the disturbance of the disturbance line 263 can deter them. If a bird stands directly on the disturbance line 263, the overall weight of the disturbance line 263 will be reduced. The addition of a second bird deterrent device involves rotating the disturbance line 263 as a whole, driven by the port active bearing 210 and the port driven bearing 230. When the line rotates to the bottom of the port sleeve 110, the deflector plate 260 separates from the port driven plate 270, performing a secondary bird deterrent. If there are no birds on the disturbance line 263, the drop plate 290 returns to its original position, and the disturbance line 263 is rotated to the top for the next bird deterrent operation. This method eliminates the need for manual bird deterrence and is suitable for bird deterrence operations on shorter lines in power grid projects. It reduces the situation where bird deterrence is less effective on short lines and solves the technical problem that current power distribution projects have not optimized bird deterrence equipment for the characteristics of shorter lines.

[0017] This utility model also uses a port sleeve 110 and its connected positioning ring 120 to fix the pole to the ground via a lightning protection plate 100 at the bottom of the positioning ring 120. Since the bottom of the pole is inserted into the ground, grounding is achieved. This allows for both equipment fixation and lightning protection, ensuring that the line disturbance structure 200 on the port sleeve 110 will not affect normal lightning protection operations while repelling birds from the transmission line. This reduces incompatibility, facilitates real-time bird repelling operations, requires no additional power, is low-cost, and is convenient for short-line bird repelling, thus solving the adaptability defects of bird repelling operations in the prior art.

[0018] Specifically, the port bushing 110 is provided with a positioning ring 120 on its outside, and a lightning protection plate 100 for connecting to the power grid grounding device is provided on the positioning ring 120. The middle part of the port bushing 110 is provided with a through hole for the transmission line to pass through, and the diameter of the through hole is larger than the diameter of the transmission line. The equipment is fixed in relative position by connecting the pole through the lightning protection plate 100, which does not add weight to the transmission line, thus realizing the bird deterrence operation of the transmission line and reducing the impact on the lightning protection performance.

[0019] Furthermore, a linkage rod 220 is provided between the port active bearing 210 and the port driven bearing 230. The extension rod 240 and the top connecting structure are positioned above the relative position of the spoiler 280 without external force. The extension rod 240 is detachably connected to the port active bearing 210 and the port driven bearing 230. The linkage rod 220 ensures that the port active bearing 210 and the port driven bearing 230 can move synchronously under external force, preventing the single movement from causing the counter plate 260 to get stuck, improving synchronization, and reducing the occurrence of wire tangling after long-term use. At the same time, the extension rod 240 is positioned at the top without external force, and it works with the disturbance line 263 to disturb the area above the transmission line, reducing the long-term stay of birds.

[0020] It is worth noting that the end of the dial plate 260 near the port active plate 250 is provided with a gravity adapter block 262 that is rotatably connected. The gravity adapter block 262 is snapped into the port active plate 250. The side of the dial plate 260 near the disturbance line 263 is provided with a wiring block 261 for fixing the disturbance line 263. The detachable design makes it easy to replace and disassemble the dial plate 260 and its connecting structure with the port active plate 250, reducing the occurrence of damage to the disturbance line 263 and making it unusable. At the same time, the gravity adapter block 262 can be directly dropped when flipped due to its rotational convenience.

[0021] It is worth mentioning that the port driven plate 270 is provided with a groove that cooperates with the toggle plate 260. The toggle plate 260 is connected to the disturbance line 263 based on the terminal block 261, and the disturbance line 263 is in a drooping state when it is fixed. When the toggle plate 260 is in the upper position, one end of it is connected and fixed to the port active plate 250 through the toggle plate 260, and the other end rests in the groove on the port driven plate 270 to adjust the height of the disturbance line 263. This reduces the occurrence of the disturbance line 263 directly contacting the transmission line, and at the same time, the drooping state reduces the occurrence of birds landing on the disturbance line 263, improving the disturbance capability in the suspended state.

[0022] It is worth noting that the bottom of the spoiler 280 is connected to the drop plate 290. The outer wall of the spoiler 280 is set in an inwardly concave state, and the drop plate 290 has an elliptical structure and a solid metal structure inside. The spoiler 280 is installed at the bottom of the port active bearing 210 and the port driven bearing 230 at a relative position. The outer wall structure of the spoiler 280 increases the windward surface, while the drop plate 290 at the bottom has a metal lining, which increases the overall weight. This ensures that the spoiler 280 and the drop plate 290 are always at a relatively bottom position when there are no external environmental factors. At the same time, under the influence of the external environment, it can achieve the purpose of swaying left and right, thereby causing the swaying of the disturbance line 263.

[0023] Working Principle: This embodiment provides a lightning protection and bird deterrent device for power distribution network engineering. In use, the lightning arrester 100 is connected to the poles at both ends of the transmission line. Then, the transmission line passes through the port bushing 110. The disturbance line 263 is connected to the connecting blocks 261 in two sets of line disturbance structures 200, ensuring it hangs downwards with a gap between it and the transmission line. When a bird is located on the transmission line within this range, the disturbance line 263 is swung by the disturbance plate 280, based on the port active bearing 210 and the port driven bearing. The bearing 230 swings left and right to drive away birds. If a bird stands directly on the disturbance line 263, the overall weight of the disturbance line 263 increases. Then, the port active bearing 210 and the port driven bearing 230 drive the disturbance line 263 to rotate as a whole. When it rotates to the bottom of the port sleeve 110, the deflector 260 separates from the port driven plate 270 and swings a second time to drive away birds. When there are no birds on the disturbance line 263, the drop plate 290 returns to its original position and rotates the disturbance line 263 to the top to drive away birds.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
