Description

Technical Field

[0001] The invention relates to the technical field of power transmission, and in particular to a porcelain insulator with a cleaning mechanism and a cleaning method thereof. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, and are able to withstand voltage and mechanical stress. Insulators are of various types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. However, after long-term outdoor placement, there will still be floating dust and various impurities covering the surface, which can easily reduce the insulation performance of the insulator.

[0003] For example, a patent entitled "A Self-cleaning Device for Porcelain Insulators" (patent application number CN202310714171.X) discloses a self-cleaning device for porcelain insulators. By setting up a cleaning mechanism, a rotating sleeve drives the connecting column to rotate, the rotating sleeve drives the top cover to rotate, the top cover drives the cleaning member to rotate, the cleaning member rotates to clean the surface of the porcelain insulator, and the cleaning member rotates to drive the blocking member to release the conflict with the opening under the action of centrifugal force, so that water in the hollow groove can enter between the cleaning member and the porcelain insulator through the opening, thereby enhancing the cleaning effect. However, the cleaning mechanism connects multiple umbrella skirts, which increases the probability of bridging of multiple umbrella skirts in rainy and snowy weather, thereby reducing the actual creepage distance.

[0004] Therefore, it is necessary to propose a porcelain insulator with a cleaning mechanism and a cleaning method thereof to solve the above problems. Summary of the invention

[0016] Preferably, a cavity is provided inside the support top seat, a power source is fixed in the cavity, and the power source is connected to the alarm light.

[0017] The present invention also discloses a porcelain insulator cleaning method with a cleaning mechanism, comprising the following steps:

[0018] The wind pushes the wind cup, so that the wind cup drives the first V-shaped scraper to rotate, and the first V-shaped scraper rotates to clean the first shed;

[0019] When the first V-shaped scraper rotates, the first magnet at the lower end of the first V-shaped scraper repels the second magnet at the upper end of the second V-shaped scraper. When the first V-shaped scraper rotates, the second V-shaped scraper rotates synchronously, and a gap is always maintained between the first V-shaped scraper and the second V-shaped scraper, thereby reducing the creepage path on the surface of the shed.

[0020] When the first V-shaped scraper rotates, it is monitored by the monitoring structure. When the first V-shaped scraper rotates, it is monitored by the monitoring structure. When it is in windy weather, wind will enter the interior of the cavity through the filter. The wind speed sensor can detect the wind. The rotation speed sensor can monitor whether the first rotating ring is in a rotating state. If it is monitored that the first rotating ring is not moving in windy weather, the monitoring structure determines that the cleaning mechanism is damaged and alarms.

[0021] Technical effects and advantages of the present invention:

[0022] 1. In the actual operation of the present invention, when the wind drives the first rotating ring to rotate through the wind cup, the first rotating ring can make a circular motion along the outer side of the first umbrella skirt, and the first V-shaped scraper connected to the bottom end can scrape the dirt on the outer side of the first umbrella skirt. Due to the V-shaped structure of the first V-shaped scraper, it fits the outer side of the first umbrella skirt, and can clean the upper and lower surfaces of the first umbrella skirt at the same time, so the cleaning effect is good.

[0023] 2. Furthermore, since the first V-shaped scraper and the second V-shaped scraper are staggered in the upper and lower parts, when the first V-shaped scraper rotates and approaches the second V-shaped scraper, the first magnet at the bottom of the first V-shaped scraper and the second magnet at the top of the second V-shaped scraper repel each other. Through the repulsive force, when the first V-shaped scraper rotates, it will synchronously push the second V-shaped scraper to rotate, thereby completing the cleaning work of the second umbrella skirt. When it is in windy weather, the wind can drive any one of the first V-shaped scraper or the second V-shaped scraper to rotate, which can drive the other first V-shaped scraper or the second V-shaped scraper to rotate.

[0024] 3. Due to the repulsive force between the first magnet and the second magnet, the first V-shaped scraper and the second V-shaped scraper will never fit together, thereby reducing the problem of bridging between the first shed and the second shed in rainy and snowy weather and reducing the actual creepage distance.

[0025] 4. In addition, since the first magnets are fixed on both sides of the lower vertical plate, the second magnets are fixed on both sides of the upper vertical plate, and the first magnets and the second magnets are of the same size, the center of gravity of the second V-shaped scraper is biased toward the side close to the core rod, and the side of the second V-shaped scraper close to the second umbrella skirt is lighter, so when the second V-shaped scraper rotates, it is easier and more stable.

[0026] 5. At the same time, since the first umbrella skirt and the second umbrella skirt are respectively provided with the first V-shaped scraper and the second V-shaped scraper, bulges are generated on the upper surfaces of the first umbrella skirt and the second umbrella skirt. In rainy and snowy weather, the first V-shaped scraper and the second V-shaped scraper can separate the rainwater accumulated on the first umbrella skirt and the second umbrella skirt to avoid the connection of rainwater.

[0027] 6. In the actual operation of the present invention, when it is in windy weather, wind will enter the interior of the cavity through the filter. The wind can be detected by the wind speed sensor, and the rotation speed sensor can monitor whether the first rotating ring is in a rotating state. If it is monitored that the first rotating ring is not moving in windy weather, it means that the cleaning structure is damaged or the insulator is damaged, resulting in the inability to rotate the first rotating ring and the insulator cleaning work cannot be completed. At this time, the monitoring mechanism transmits a signal to the controller, and the controller can control the alarm light to flash, reminding personnel that the cleaning structure needs to be repaired. The monitoring efficiency is high, and there is no need for personnel to manually climb up the power tower for maintenance.

[0028] 7. In the actual operation of the present invention, if cracks are generated in the first umbrella skirt and the second umbrella skirt due to lightning strike, the limit column inside the embedded groove will extend downward by its own gravity and extend into the inside of the crack to play a fixing role. When the first V-shaped scraper or the second V-shaped scraper rotates, resistance will be generated to prevent the first V-shaped scraper or the second V-shaped scraper from rotating, so that the monitoring structure reminds personnel to perform inspection and maintenance.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention provides Figure 1 - Figure 7A porcelain insulator with a cleaning mechanism and a cleaning method thereof are shown, comprising a core rod 1, an outer side of the core rod 1 is fixed with an umbrella skirt, the umbrella skirt comprises a first umbrella skirt 2 and a second umbrella skirt 27, the first umbrella skirt 2 and the second umbrella skirt 27 are distributed along the height direction of the core rod 1, and a spacing is left between the first umbrella skirt 2 and the second umbrella skirt 27, a support top seat 5 is fixed to the top end of the core rod 1, a plurality of the first umbrella skirt 2 and the second umbrella skirt 27 are arranged at intervals from each other, a steel foot 3 is fixed to the bottom end of the core rod 1, and the outer side thread of the steel foot 3 is matched with a first nut 4, by adding a plurality of first umbrella skirts 2 and second umbrella skirts 27, the surface discharge distance can be effectively increased, which helps to prevent the discharge phenomenon occurring on the surface of the insulator in a high-voltage electric field, thereby protecting the insulator from arc damage.

[0039] It should be noted that the radius of the first shed 2 and the second shed 27 can be set to be one large and one small. By changing the areas of the upper and lower sheds, bridging between the sheds can be prevented in rainy and snowy weather, and the pollution and moisture conditions of the insulator can be improved.

[0040] A cleaning mechanism is arranged on the outer side of the core rod 1, and the cleaning mechanism includes a first swivel 9, a second swivel 18, a first V-shaped scraper 13 and a second V-shaped scraper. The first swivel 9 and the second swivel 18 are both rotatably connected to the outer side of the core rod 1, and the first swivel 9 is arranged above the first umbrella skirt 2, and the second swivel 18 is arranged above the second umbrella skirt 27. Four protruding blocks 10 are fixed to the outer side of the first swivel 9, and wind cups 12 are arranged at the tops of the four protruding blocks 10. Connecting rods 11 are fixed to the tops of the four protruding blocks 10, and the wind cups 12 are fixed to the tops of the corresponding connecting rods 11. The wind cups 12 are composed of hemispherical empty cups. When there is wind, the wind force will impact the inside of the wind cups 12, and push the wind cups 12 to drive the first swivel 9 to rotate, thereby rotating the cleaning mechanism package.

[0041] The first V-shaped scraper 13 is connected to the bottom end of the first swivel 9, and the second V-shaped scraper 14 is connected to the outer side of the second swivel 18. The inner sides of the first V-shaped scraper 13 and the second V-shaped scraper 14 are respectively attached to the outer surfaces of the first umbrella skirt 2 and the second umbrella skirt 27, and the first V-shaped scraper 13 and the second V-shaped scraper 14 are staggered up and down.

[0042] A lower vertical plate 19 is fixed to the bottom end of the first V-shaped scraper 13 and the second V-shaped scraper 14, an upper vertical plate 20 is fixed to the top end of the first V-shaped scraper 13 and the second V-shaped scraper 14, and a first magnet 21 and a second magnet 22 are fixed on both sides of the lower vertical plate 19 and the upper vertical plate 20, respectively. The first magnet 21 at the bottom end of the first V-shaped scraper 13 and the second magnet 22 at the top end of the second V-shaped scraper 14 repel each other.

[0043] It should be noted that when more umbrella skirts need to be added below the second umbrella skirt 27 , multiple cleaning structures having the same structure as the second V-shaped scraper 14 need to be added to the outside of the umbrella skirt.

[0044] In the actual operation of the present invention, when the wind force drives the first swivel 9 to rotate through the wind cup 12, the first swivel 9 can make a circular motion along the outer side of the first umbrella skirt 2, and the first V-shaped scraper 13 connected to the bottom end can scrape off the dirt on the outer side of the first umbrella skirt 2. Due to the V-shaped structure of the first V-shaped scraper 13, which fits the outer side of the first umbrella skirt 2, the upper and lower surfaces of the first umbrella skirt 2 can be cleaned at the same time, and the cleaning effect is good.

[0045] Furthermore, since the first V-shaped scraper 13 and the second V-shaped scraper 14 are staggered in the upper and lower parts, when the first V-shaped scraper 13 rotates and approaches the second V-shaped scraper 14, the first magnet 21 at the bottom of the first V-shaped scraper 13 and the second magnet 22 at the top of the second V-shaped scraper 14 repel each other. Through the repulsive force, when the first V-shaped scraper 13 rotates, it will synchronously push the second V-shaped scraper 14 to rotate, thereby completing the cleaning work of the second umbrella skirt 27.

[0046] In addition, due to the repulsive force of the first magnet 21 and the second magnet 22, the first V-shaped scraper 13 and the second V-shaped scraper 14 will never fit together, thereby reducing the problem of bridging between the first umbrella skirt 2 and the second umbrella skirt 27 in rainy and snowy weather and reducing the actual creepage distance.

[0047] In addition, since the first magnets 21 are fixed on both sides of the lower vertical plate 19, the second magnets 22 are fixed on both sides of the upper vertical plate 20, and the first magnets 21 and the second magnets 22 are of the same size, the center of gravity of the second V-shaped scraper 14 is biased toward the side close to the core rod 1, and the side of the second V-shaped scraper 14 close to the second umbrella skirt 27 is lighter, so when the second V-shaped scraper 14 rotates, it is easier and more stable.

[0048] At the same time, since the first umbrella skirt 2 and the second umbrella skirt 27 are respectively provided with the first V-shaped scraper 13 and the second V-shaped scraper 14, bulges are generated on the upper surfaces of the first umbrella skirt 2 and the second umbrella skirt 27. In rainy and snowy weather, the first V-shaped scraper 13 and the second V-shaped scraper 14 can separate the rainwater accumulated on the first umbrella skirt 2 and the second umbrella skirt 27 to avoid the connection of rainwater.

[0049] Meanwhile, when it is windy, the wind can drive any one of the first V-shaped scraper blades 13 or the second V-shaped scraper blades 14 to rotate, thereby driving the other first V-shaped scraper blades 13 or the second V-shaped scraper blades 14 to rotate.

[0050] A pull ring 23 is fixed to one side of one of the protruding blocks 10, and a cavity is opened inside the protruding block 10, and a filter 24 is provided on one side of the protruding block 10 for wind to enter, and a monitoring mechanism is provided inside the cavity, the monitoring mechanism includes a wind speed sensor and a rotation speed sensor, and the monitoring mechanism is connected to a solar power supply module, the solar power supply module is used to power the wind speed sensor and the rotation speed sensor, and the specific solar power supply module can be installed on a utility pole or near an insulator, and is connected to the monitoring mechanism through wires, the solar power supply module includes a solar panel and a solar cell group, and since the solar power supply module is a prior art, it will not be described in detail.

[0051] The outer side of the support top 5 is embedded with an alarm light 28 and a controller, and the monitoring mechanism, the controller and the alarm light 28 are connected in sequence. The solar power supply module can supply power to the monitoring mechanism and also to the alarm light 28.

[0052] In the actual operation of the present invention, when it is in windy weather, wind will enter the interior of the cavity through the filter 24, and the wind can be detected by the wind speed sensor. The rotation speed sensor can monitor whether the first rotating ring 9 is in a rotating state. If it is monitored that the first rotating ring 9 is not moving in windy weather, it means that the cleaning structure is damaged or the insulator is damaged, resulting in the inability to rotate the first rotating ring 9 and the insulator cleaning work cannot be completed.

[0053] At this time, the monitoring mechanism transmits a signal to the controller, and the controller can control the alarm light 28 to flash, reminding personnel that the cleaning structure needs to be repaired. The monitoring efficiency is high, and personnel do not need to manually climb up the power tower for maintenance.

[0054] The first V-shaped scraper 13 and the second V-shaped scraper 14 are both fitted on the upper surface of the umbrella skirt with an embedded groove 25, and a limiting column 26 is slidably arranged inside the embedded groove 25. A silicone pad is fixedly arranged at the bottom of the limiting column 26. The limiting column 26 is made of a hard material, and the silicone pad is a soft material, which can avoid the bottom end blocking the rotation of the first V-shaped scraper 13. 26 is set to a conical needle shape, and the tip of the conical needle faces downward. A plurality of embedded grooves 25 are provided, and the plurality of limiting columns 26 are equidistantly distributed along the length direction of the first V-shaped scraper 13.

[0055] In the actual operation of the present invention, if cracks are generated in the first umbrella skirt 2 and the second umbrella skirt 27 due to lightning strike, the limiting column 26 inside the embedded groove 25 will extend downward by its own gravity and extend into the inside of the crack to play a fixing role. When the first V-shaped scraper 13 or the second V-shaped scraper 14 rotates, resistance will be generated to prevent the first V-shaped scraper 13 or the second V-shaped scraper 14 from rotating, so that the monitoring structure reminds personnel to perform inspection and maintenance.

[0056] It should be noted that if the first umbrella skirt 2 and the second umbrella skirt 27 are not damaged, since the surfaces of the first umbrella skirt 2 and the second umbrella skirt 27 are relatively smooth, during the rotation process, the limiting column 26 is blocked by the surface and will retract into the interior of the embedded groove 25. The number and arrangement of the limiting columns 26 can be selectively used as needed. In another embodiment, a spring can be added inside the embedded groove 25 to connect the limiting columns 26 using the spring.

[0057] The first V-shaped scraper 13 is connected to the bottom end of the first swivel 9 through the corresponding upper vertical plate 20, and the second V-shaped scraper 14 is fixedly connected to the outer side of the second swivel 18 through the corresponding upper vertical plate 20. A gap is left between the upper vertical plate 20, the lower vertical plate 19 and the outer side of the core rod 1 to avoid collision and friction between the upper vertical plate 20, the lower vertical plate 19 and the core rod 1 during rotation, resulting in a reduction in the rotation amplitude.

[0058] Threaded rods 15 are fixed on both sides of the top of the support top seat 5, and pressure plates 16 are sleeved on the outer sides of the two threaded rods 15. The outer threads of the threaded rods 15 are matched with second nuts 17, and the two second nuts 17 are pressed tightly on the top of the pressure plates 16. A cable groove 6 for fixing the cable is opened in the middle of the top of the support top seat 5 and the side opposite to the pressure plate 16. A protective cover 7 is sleeved on the outer side of the support top seat 5, and a through groove 8 corresponding to the cable groove 6 is opened on the outer side of the protective cover 7.

[0059] The cable that needs to be supported can be placed inside the cable trough 6, and the upper surface of the cable can be pressed and fixed by the pressing plate 16 to prevent the cable from moving. At the same time, the supporting area of ​​the cable can be protected and insulated by the protective cover 7.

[0060] The present invention also discloses a porcelain insulator cleaning method with a cleaning mechanism, comprising the following steps:

[0061] The wind force pushes the wind cup 12, so that the wind cup 12 drives the first V-shaped scraper 13 to rotate, and the first V-shaped scraper 13 rotates to clean the first umbrella skirt 2;

[0062] When the first V-shaped scraper 13 rotates, the first magnet 21 at the lower end of the first V-shaped scraper 13 and the second magnet 22 at the upper end of the second V-shaped scraper 14 repel each other. When the first V-shaped scraper 13 rotates, the second V-shaped scraper 14 rotates synchronously, and a gap is always maintained between the first V-shaped scraper 13 and the second V-shaped scraper 14, thereby reducing the creepage path on the surface of the shed.

[0063] When the first V-shaped scraper 13 rotates, it is monitored by the monitoring structure. When the first V-shaped scraper 13 rotates, it is monitored by the monitoring structure. When it is in windy weather, wind will enter the interior of the cavity through the filter 24. The wind speed sensor can detect the wind. The speed sensor can monitor whether the first rotating ring 9 is in a rotating state. If it is monitored that it is in windy weather and the first rotating ring 9 is not moving, the monitoring structure determines that the cleaning mechanism is damaged and alarms.

The porcelain insulator with a cleaning mechanism according to claim 1, characterized in that: A plurality of the first umbrella skirts (2) and the second umbrella skirts (27) are arranged at intervals from each other. A steel foot (3) is fixed to the bottom end of the core rod (1), and the outer side thread of the steel foot (3) is matched with a first nut (4).

8. The porcelain insulator with a cleaning mechanism according to claim 6, characterized in that: Threaded rods (15) are fixed on both sides of the top of the support top seat (5), and pressure plates (16) are sleeved on the outer sides of the two threaded rods (15). The outer threads of the threaded rods (15) are matched with second nuts (17), and the two second nuts (17) are pressed tightly on the top of the pressure plates (16). A cable groove (6) for fixing the cable is provided in the middle of the top of the support top seat (5) and the side opposite to the pressure plate (16). A protective cover (7) is sleeved on the outer side of the support top seat (5), and a through groove (8) corresponding to the cable groove (6) is provided on the outer side of the protective cover (7).

9. A porcelain insulator with a cleaning mechanism according to claim 6, characterized in that: A cavity is arranged inside the supporting top seat (5).

10. A method for cleaning a porcelain insulator with a cleaning mechanism, comprising the porcelain insulator with a cleaning mechanism as claimed in any one of claims 1 to 9, and further comprising the following steps: The wind force pushes the wind cup (12), so that the wind cup (12) drives the first V-shaped scraper (13) to rotate, and the first V-shaped scraper (13) rotates to clean the first umbrella skirt (2); When the first V-shaped scraper (13) rotates, the first magnet (21) at the lower end of the first V-shaped scraper (13) and the second magnet (22) at the upper end of the second V-shaped scraper (14) repel each other, so when the first V-shaped scraper (13) rotates, the second V-shaped scraper (14) rotates synchronously, and a gap is always maintained between the first V-shaped scraper (13) and the second V-shaped scraper (14), thereby reducing the creepage path on the surface of the shed. When the first V-shaped scraper (13) rotates, it is monitored by the monitoring structure. When it is in windy weather, wind will enter the interior of the cavity through the filter (24). The wind speed sensor detects the presence of wind. The rotation speed sensor monitors whether the first rotating ring (9) is in a rotating state. If it is detected that it is in windy weather and the first rotating ring (9) is not moving, the monitoring structure determines that the cleaning mechanism is damaged and alarms.
