Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to insulators for power distribution networks. Background Technology

[0002] Insulators are widely used in power distribution networks. They are devices installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. While the structure and appearance of different types of insulators vary considerably, they all consist of two main parts: insulating components and connecting hardware. Insulators are a special type of insulating control that plays a crucial role in overhead transmission lines. In the early days, insulators were mostly used on utility poles. Gradually, they evolved into the use of disc-shaped insulators hanging at one end of high-voltage power line towers to increase creepage distance. These are typically made of glass or ceramic and are called insulators. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions; otherwise, they will not function effectively and will damage the service life and operational life of the entire line.

[0003] In the current distribution network, insulators are often contaminated with bird droppings and other pollutants during use. These pollutants reduce the insulation performance of the insulators. In addition, existing porcelain insulators are usually fixedly connected to insulator mounting frames. However, when the wind is strong, the power lines will sway. When the power lines sway, they will exert a large impact force on the insulator skirts, which can easily lead to the skirts being damaged by large torsional forces. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a distribution network insulator to solve the problems of bird droppings contaminating insulators and the skirts being easily damaged by impact in the above-mentioned background art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A distribution network insulator includes a crossarm, a bottom mounting rod, a fixing bolt, a bottom connecting sleeve, a ceramic column, and an insulator umbrella. The bottom mounting rod is vertically embedded in the middle of the crossarm. A fixing bolt is nested on the upper part of the outer wall of the bottom mounting rod. A bottom connecting sleeve is fixed to the top of the bottom mounting rod. A ceramic column is embedded and fixed inside the upper part of the bottom connecting sleeve. An insulator umbrella is fixed to the outer wall of the ceramic column. A bottom ball bearing is nested on the outer wall of the bottom connecting sleeve. A top connecting sleeve is fixed to the top of the ceramic column. A top ball bearing is nested on the outer wall of the top connecting sleeve. A cleaning plate is fixed to the left side of the top ball bearing. A wind cup is fixed to the outer wall of both the top ball bearing and the bottom ball bearing.

[0007] An outer frame is embedded inside the wind cup, and an inner frame is embedded inside the outer frame. Mirror panels are fixed to the outer surfaces of both the outer and inner frames. A connecting post is vertically fixed to the center of the top of the top connecting sleeve. A buffer spring is connected to the connecting post. An outer cylinder is connected to the outer wall of the buffer spring. An installation plate is fixed to the top of the outer cylinder.

[0008] With the above technical solution, when wind blows towards the insulator during use, the wind will simultaneously exert force on the two wind cups on the outer sides of the bottom ball bearing and the top ball bearing. After being subjected to force, the wind cups will drive the top ball bearing and the bottom ball bearing connected to them to rotate. Since the cleaning plate is fixed between the top ball bearing and the bottom ball bearing, the cleaning plate will rotate with the rotation of the bottom ball bearing and the top ball bearing to automatically scrape and clean the contaminants such as bird droppings adhering to the ceramic column and the outer wall of the insulator umbrella. This can minimize the contamination and damage of the insulator by bird droppings and other contaminants. When the wind blows the wind cups to rotate, the wind will also blow towards the outer frame and the inner frame inside the wind cups. This causes the outer frame to rotate back and forth inside the wind cups and the inner frame to rotate left and right inside the outer frame. By reflecting sunlight at multiple angles through the installed mirror panel, birds are driven away from the insulator, reducing the number of birds staying and excreting droppings.

[0009] In one possible implementation, the cleaning plate is fixed between the left side of the top ball bearing and the left side of the bottom ball bearing, with the outer left side of the ceramic column and the insulator umbrella tightly attached to the inner wall of the cleaning plate.

[0010] Through the above technical solution, the cleaning plate that is closely attached to the ceramic post and the insulator umbrella will perform all-round scraping and cleaning on the surface of the ceramic post and the insulator umbrella during the rotation process, which can effectively avoid the phenomenon of a large amount of bird droppings and other pollutants sticking to the surface of the ceramic post and the insulator umbrella.

[0011] In one possible implementation, the cleaning plate rotates horizontally on the outer wall of the ceramic column and the insulator umbrella via a top ball bearing and a bottom ball bearing, and the end of the cleaning plate that is in close contact with the outer wall of the ceramic column and the insulator umbrella is provided with soft bristles.

[0012] Through the above technical solution, the bottom ball bearing and the top ball bearing drive the cleaning plate to rotate and clean the outer wall of the ceramic column and the insulator umbrella that are in close contact. The soft bristles set on the inner wall of the cleaning plate can reduce the wear caused to the surface of the ceramic column and the insulator umbrella during the cleaning process, and avoid the generation of a large number of scratches on the surface of the ceramic column and the insulator umbrella after cleaning.

[0013] In one possible implementation, 3-6 air cups are fixed to the outer walls of both the top and bottom ball bearings, and the air cups are arranged in a circular, equidistant pattern around the middle of the top and bottom ball bearings.

[0014] With the above technical solution, the arrangement of multiple wind cups ensures that at least one wind cup will be pushed by the wind force regardless of the direction of the wind, thereby generating a torque around the central axis of the bottom ball bearing and the top ball bearing, causing the wind cup to rotate rapidly.

[0015] In one possible implementation, both the middle portion of the wind cup and the middle portion of the outer frame have a rectangular opening from front to back. The outer frame is disposed in the rectangular opening of the wind cup, and the inner frame is disposed in the rectangular opening of the outer frame.

[0016] In one possible implementation, the left and right ends of the outer frame are each laterally fixed with a shaft, and the shafts at the left and right ends of the outer frame are precisely embedded in the left and right ends of the "rectangular opening" inside the wind cup. The outer frame rotates back and forth in the "rectangular opening" of the wind cup through the shafts.

[0017] In one possible implementation, the upper and lower ends of the inner frame are both vertically fixed with shafts, and the shafts at the upper and lower ends of the inner frame are precisely embedded in the upper and lower ends of the "rectangular opening" inside the outer frame. The inner frame can rotate left and right in the "rectangular opening" of the outer frame through the shafts.

[0018] In one possible implementation, mirror panels are fixed to the front and rear ends and the top and bottom ends of the outer frame, and mirror panels are fixed to the front and rear ends and the left and right ends of the inner frame.

[0019] With the above technical solution, since the outer frame rotates back and forth inside the wind cup, the mirror panels at the front, back, top, and bottom of the rotating outer frame can reflect sunlight. Since the inner frame rotates left and right inside the outer frame, the mirror panels at the front, back, left, and right of the rotating inner frame can reflect sunlight, thus achieving multi-angle reflection of sunlight and a better bird-repelling effect.

[0020] As the wind blows and the insulator rotates, the wind also blows onto the outer and inner frames inside the insulator. This causes the outer frame to rotate back and forth inside the insulator, and the inner frame to rotate left and right inside the outer frame. The mirror panels installed on the inner and outer frames reflect sunlight at multiple angles, thus driving birds away from the insulator, reducing bird stays and droppings, and further improving the service life of the insulator.

[0021] In one possible implementation, the middle part of the connecting column and the middle part of the outer cylinder are on the same vertical horizontal plane, and the distance between the outer wall of the connecting column and the outer cylinder, and the distance between the top of the connecting column and the upper part of the inner cavity of the outer cylinder are both 0.3-0.8cm.

[0022] In one possible implementation, buffer springs are connected to the top of the connecting column and the front, rear, left, and right ends of the outer wall. The end of the buffer spring away from the connecting column is connected to the upper interior of the outer cylinder and the inner wall, respectively.

[0023] With the above technical solution, when the ceramic column is shaken by wind, the connecting column above the ceramic column will move upward or sway at any angle, left, right, forward or backward. At this time, the moving connecting column will squeeze or pull the buffer spring connected to the outer cylinder to deform, thereby buffering the impact force on the ceramic column. The buffering effect is good, which can reduce the impact force on the insulator umbrella and the ceramic column, and further improve the service life of the insulator.

[0024] The beneficial effects of this utility model are:

[0025] 1. By adopting the technical solution of this application, when wind blows towards the insulator during use, the wind will simultaneously exert force on the two wind cups on the outer side of the bottom ball bearing and the top ball bearing. After being subjected to force, the wind cups will drive the top ball bearing and the bottom ball bearing connected to them to rotate. Since the cleaning plate is fixed between the top ball bearing and the bottom ball bearing, the cleaning plate will rotate with the rotation of the bottom ball bearing and the top ball bearing to automatically scrape and clean the contaminants such as bird droppings adhering to the ceramic column and the outer wall of the insulator umbrella. This can minimize the pollution and damage of bird droppings and other contaminants to the insulator. When the wind blows the wind cups to rotate, the wind will also blow towards the outer frame and the inner frame inside the wind cups. This causes the outer frame to be subjected to force and rotate back and forth inside the wind cups, and the inner frame to be subjected to force and rotate left and right in the outer frame. By reflecting sunlight at multiple angles through the installed mirror panel, birds are driven away from the insulator, reducing the number of birds staying and excreting droppings.

[0026] 2. By adopting the technical solution of this application, when the ceramic column is shaken by wind, the connecting column above the ceramic column will move upward or sway at any angle from left to right or forward to backward. Since the top and outer wall of the connecting column are equipped with buffer springs connected to the inner wall of the outer cylinder, the moving connecting column will deform by squeezing or pulling the buffer springs connected to the outer cylinder, thereby buffering the impact force on the ceramic column. The buffering effect is good, which may reduce the impact force on the insulator umbrella and the ceramic column, and further improve the service life of the insulator. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0042] Example 1, as Figures 1-5 As shown, the distribution network insulator includes a crossarm 1, a bottom mounting rod 2, a fixing bolt 201, a bottom connecting sleeve 202, a ceramic column 3, and an insulator umbrella 301. The bottom mounting rod 2 is vertically embedded in the middle of the crossarm 1. The fixing bolt 201 is nested on the upper part of the outer wall of the bottom mounting rod 2. The bottom connecting sleeve 202 is fixed on the top of the bottom mounting rod 2. The ceramic column 3 is embedded and fixed inside the upper part of the bottom connecting sleeve 202. The insulator umbrella 301 is fixed on the outer wall of the ceramic column 3. The bottom ball bearing 203 is nested on the outer wall of the bottom connecting sleeve 202. The top connecting sleeve 4 is fixed on the top of the ceramic column 3. The top ball bearing 401 is nested on the outer wall of the top connecting sleeve 4. A cleaning plate 402 is fixed on the left side of the top ball bearing 401. Wind cups 5 are fixed on the outer walls of both the top ball bearing 401 and the bottom ball bearing 203.

[0043] An outer frame 501 is embedded inside the wind cup 5, and an inner frame 502 is embedded inside the outer frame 501. Mirror panels 503 are fixed to the outer surfaces of both the outer frame 501 and the inner frame 502. A connecting post 6 is vertically fixed to the center of the top of the top connecting sleeve 4. A buffer spring 601 is connected to the connecting post 6. An outer cylinder 602 is connected to the outer wall of the buffer spring 601. An installation plate 603 is fixed to the top of the outer cylinder 602.

[0044] Specifically, the outer wall and top of the connecting column 6 are elastically connected to the inner wall and top of the outer cylinder 602 through multiple sets of buffer springs 601. The outer wall and top of the connecting column 6 are welded to the buffer springs 601. Annular grooves (not shown in the figure) are provided on the inner wall of the outer cylinder 602. Metal retaining rings (not shown in the figure) are embedded in the annular grooves, and the metal retaining rings and annular grooves are interference-fitted. A U-shaped hook (not shown in the figure) is connected to the end of the buffer spring 601 away from the connecting column 6. The U-shaped hook is connected to the metal retaining ring to form an elastic connection.

[0045] Mounting plate 603 is a circular metal plate with six bolt holes evenly distributed along its edge (the hole diameter matches the bolts on the pole), used to fix it to the pole with high-strength bolts.

[0046] Align the bolt holes of the mounting plate 603 with the preset installation position on the pole, and tighten them with high-strength bolts to ensure a rigid connection between the insulator and the pole.

[0047] In one possible embodiment, the cleaning plate 402 is fixed between the left side of the top ball bearing 401 and the left side of the bottom ball bearing 203, and the outer left side of the ceramic column 3 and the insulator umbrella 301 is in close contact with the inner wall of the cleaning plate 402.

[0048] Through the above technical solution, the cleaning plate 402, which is closely attached to the ceramic post 3 and the insulator umbrella 301, will perform all-round scraping and cleaning of the ceramic post 3 and the insulator umbrella 301 during the rotation process, which can effectively avoid the phenomenon of a large amount of bird droppings and other pollutants sticking to the surface of the ceramic post 3 and the insulator umbrella 301.

[0049] In one possible embodiment, the cleaning plate 402 rotates horizontally on the outer wall of the ceramic column 3 and the insulator umbrella 301 via the top ball bearing 401 and the bottom ball bearing 203, and the cleaning plate 402 is provided with soft bristles at one end that is in close contact with the outer wall of the ceramic column 3 and the insulator umbrella 301.

[0050] Through the above technical solution, the bottom ball bearing 203 and the top ball bearing 401 drive the cleaning plate 402 to rotate and clean the outer wall of the closely attached ceramic column 3 and insulator umbrella 301. The soft bristles on the inner wall of the cleaning plate 402 can reduce the wear caused to the surface of the ceramic column 3 and insulator umbrella 301 during the cleaning process, and avoid a large number of scratches after the surface of the ceramic column 3 and insulator umbrella 301 is cleaned.

[0051] When the insulator is installed and wind blows towards it, the wind will exert a force on the two wind cups 5 on the outer side of the bottom ball bearing 203 and the top ball bearing 401. After being subjected to force, the wind cups 5 will drive the top ball bearing 401 and the bottom ball bearing 203 connected to them to rotate. Since the cleaning plate 402 is fixed between the top ball bearing 401 and the bottom ball bearing 203, the cleaning plate 402 will rotate along with the rotation of the bottom ball bearing 203 and the top ball bearing 401. At this time, the rotating cleaning plate 402 will automatically scrape and clean the bird droppings and other contaminants adhering to the ceramic column 3 and the outer wall of the insulator umbrella 301. This can minimize the pollution and damage to the insulator caused by bird droppings and other contaminants adhering to the insulator for a long time, improve the service life of the insulator, and eliminate the need for workers to climb high to clean the insulator installed at high places. This makes it safer and more convenient to use.

[0052] In one possible embodiment, 3-6 air cups 5 are fixed to the outer walls of both the top ball bearing 401 and the bottom ball bearing 203. The air cups 5 are arranged in a circular shape at equal intervals around the middle of the top ball bearing 401 and the bottom ball bearing 203.

[0053] Through the above technical solution, the arrangement of multiple wind cups 5 ensures that no matter which direction the wind blows from, at least one wind cup 5 will be pushed by the wind force, thereby generating a torque around the central axis of the bottom ball bearing 203 and the top ball bearing 401, causing the wind cup 5 to rotate rapidly.

[0054] In one possible embodiment, both the middle part of the wind cup 5 and the middle part of the outer frame 501 have a rectangular opening from front to back. The outer frame 501 is disposed in the rectangular opening of the wind cup 5, and the inner frame 502 is disposed in the rectangular opening of the outer frame 501.

[0055] In one possible embodiment, the left and right ends of the outer frame 501 are both laterally fixed with shafts, and the shafts at the left and right ends of the outer frame 501 are precisely embedded in the left and right ends of the "rectangular opening" inside the wind cup 5. The outer frame 501 rotates back and forth in the "rectangular opening" of the wind cup 5 through the shafts.

[0056] In one possible embodiment, the inner frame 502 is vertically fixed with shafts at both the upper and lower ends, and the shafts at the upper and lower ends of the inner frame 502 are precisely embedded in the upper and lower ends of the "rectangular opening" inside the outer frame 501. The inner frame 502 can rotate left and right in the "rectangular opening" of the outer frame 501 through the shafts.

[0057] The rectangular openings in the wind cup 5 and the outer frame 501 facilitate the normal passage of airflow, allowing the outer frame 501 inside the wind cup 5 to rotate simultaneously and reflect sunlight to drive away birds when the wind cup 5 rotates.

[0058] In one possible embodiment, mirror panels 503 are fixed to the front and rear ends and the top and bottom ends of the outer frame 501, and mirror panels 503 are fixed to the front and rear ends and the left and right ends of the inner frame 502.

[0059] Through the above technical solution, since the outer frame 501 rotates back and forth inside the wind cup 5, the mirror panels 503 at the front, back and top and bottom of the rotating outer frame 501 can reflect sunlight. Since the inner frame 502 rotates left and right inside the outer frame 501, the mirror panels 503 at the front, back and left and right of the rotating inner frame 502 can reflect sunlight, thus achieving multi-angle reflection of sunlight and a better bird-repelling effect.

[0060] As the wind blows and the wind cup 5 rotates, the wind also blows onto the outer frame 501 and the inner frame 502 inside the wind cup 5. This causes the outer frame 501 to rotate back and forth inside the wind cup 5, and the inner frame 502 to rotate left and right inside the outer frame 501. The mirror panels 503 installed on the inner frame 502 and the outer frame 501 reflect sunlight at multiple angles, thereby driving birds away from the insulator, reducing the number of birds staying and excreting droppings, and further improving the service life of the insulator.

[0061] Example 2 differs from Example 1 in that, in this example, the middle part of the connecting column 6 and the middle part of the outer cylinder 602 are on the same vertical horizontal plane, and the distance between the outer wall of the connecting column 6 and the outer cylinder 602, and the distance between the top of the connecting column 6 and the upper part of the inner cavity of the outer cylinder 602 are both 0.3-0.8cm.

[0062] Because there is a gap between the outer wall and top of the connecting column 6 and the inner wall of the outer cylinder 602, the connecting column 6 can be prevented from directly impacting the interior of the outer cylinder 602 during shaking, thus avoiding damage between the outer cylinder 602 and the connecting column 6.

[0063] A buffer spring 601 is fixed to the top of the connecting column 6 and the front, back, left and right ends of the outer wall. The end of the buffer spring 601 away from the connecting column 6 is connected to the upper part of the inner wall of the outer cylinder 602 and the inner wall, respectively.

[0064] With the above technical solution, when the ceramic column 3 is shaken by the wind, the connecting column 6 above the ceramic column 3 will move up or sway at any angle, left, right, forward or backward. At this time, the moving connecting column 6 will deform by squeezing or pulling the buffer spring 601 connected to the outer cylinder 602 to buffer the impact force on the ceramic column 3. The buffering effect is good, which can reduce the impact force on the insulator umbrella 301 and the ceramic column 3, and further improve the service life of the insulator.
