A type of porcelain rod-shaped insulator with wind-powered dust removal function

Abstract

This invention discloses a ceramic rod-shaped insulator with wind-powered dust removal technology, comprising an insulating rod with connecting caps at both ends, a skirt assembly on the insulating rod, and a large skirt with a diameter larger than the skirt assembly on the outer wall of the connecting cap at the top. A cleaning mechanism is provided above the large skirt for cleaning it. This invention effectively prevents dirt from adhering to the skirt assembly surface by using a large skirt to shield it. Simultaneously, the cleaning mechanism dynamically cleans the large skirt. Under the action of external wind, a non-powered wind turbine drives the mounting base in a circular motion. During this motion, a brush continuously rubs the top wall of the large skirt, removing the adhering dirt and preventing the porcelain insulator's insulation performance from deteriorating due to dirt accumulation, thus avoiding damage to the protected device.

Description

Technical Field

[0001] This invention relates to the field of insulators, and more specifically to a ceramic rod-shaped insulator with wind-powered dust removal. Background Technology

[0002] Porcelain rod insulators are rigid insulating components used in high-voltage transmission lines and electrical equipment. They typically consist of an insulating rod, skirts, and connecting caps. When used outdoors for extended periods, porcelain rod insulators often face the problem of dust, snow, and bird droppings accumulating on the skirt surface. This contamination reduces the insulation performance of the insulator, potentially damaging the protected devices. Furthermore, porcelain rod insulators are susceptible to bird infestation, as birds often nest or perch on them, exacerbating contamination accumulation and potentially causing short circuits due to bird contact with the conductor. To address this issue, we propose a porcelain rod insulator with wind-powered dust removal capabilities. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic rod-shaped insulator with wind-powered dust removal, which solves the technical problem that dirt on the surface of the sheds of existing ceramic rod-shaped insulators affects the performance of the ceramic insulator and easily causes damage to the protected devices.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A ceramic rod-shaped insulator with wind-powered dust removal includes an insulating rod with connecting caps at both ends. The insulating rod has a skirt assembly, and the outer wall of the connecting cap at the top has a large skirt with a diameter larger than the skirt assembly. A cleaning mechanism is located above the large skirt for cleaning it. The cleaning mechanism includes a connecting bearing rotatably mounted on the outer wall of the top connecting cap, several sets of mounting seats connected to the connecting bearing via connecting blocks, a brush located at the bottom of the mounting seats and in contact with the top wall of the large skirt, and a non-powered wind ball rotatably mounted on the outer wall of the top connecting cap and located above the connecting bearing. The outer wall of the non-powered wind ball is connected to the several sets of mounting seats via brackets. Driven by external wind, the non-powered wind ball causes the mounting seats, brush, and connecting bearing to move in a circular motion relative to the top connecting cap.

[0006] A further improvement is that the umbrella skirt assembly includes several sets of first umbrella skirts disposed on the outer wall of the insulating rod, and a second umbrella skirt is disposed between two adjacent sets of first umbrella skirts, wherein the diameter of the first umbrella skirt is larger than the diameter of the second umbrella skirt.

[0007] A further improvement is that the mounting base has a channel, a ball is movably mounted in the channel, a driving mechanism is provided in the mounting base at the outer end of the channel, and a sound-generating mechanism is provided in the mounting base at the inner end of the channel. The driving mechanism is used to intermittently push the ball to strike the sound-generating mechanism when the mounting base is in circular motion. The sound-generating mechanism is used to generate sound and transmit vibration force to the mounting base.

[0008] A further improvement is that the drive mechanism includes a roller rotatably disposed on the outer edge of the large umbrella skirt, a mounting block disposed on the outer end of the mounting base, a movable cavity 1 opened in the mounting base and located at the outer end of the channel, and a top rod movably disposed in the movable cavity 1. One end of the top rod extends into the channel, and the other end is connected to the inner wall of the movable cavity 1 through an elastic element. The shaft of the roller extends into the mounting block and is fitted with a toothed gear. One side of the toothed gear is meshed with a gear shaft. A pull rope is wound around the outer wall of the gear shaft, and the other end of the pull rope extends into the movable cavity 1 and is connected to the top rod.

[0009] A further improvement is that the sound-generating mechanism includes a second movable cavity that is opened in the mounting base and communicates with the inner end of the channel. The second movable cavity is provided with a first rotating column, and the outer wall of the first rotating column is provided with a sound-generating plate for contacting the sphere.

[0010] A further improvement is that the outer circumference of the rotating column one is provided with several sets of recesses, and each set of recesses is provided with a sound-emitting plate, and the thickness of each set of sound-emitting plates is different. The rotating column one is rotatably mounted in the movable cavity two via a rotating shaft. One end of the rotating shaft passes through the mounting base and is provided with a transmission component. The transmission component is used to intermittently drive the rotating shaft to rotate the rotating column one by a preset angle when the mounting base performs circumferential motion, so that the several sets of sound-emitting plates correspond to the channels in sequence.

[0011] A further improvement is that the transmission component includes a first protective seat mounted on a mounting base and movably sleeved on the outside of the rotating shaft, and a second protective seat mounted on a connecting block. A drive shaft is rotatably mounted inside the second protective seat. One end of the drive shaft passes through the second protective seat and is fitted with a transmission gear. A support ring is provided inside the transmission gear. The support ring is fixedly sleeved on the top connecting cap. The outer circumference of the support ring is provided with several sets of arc-shaped racks for driving the transmission gear to rotate. A coupling is provided between the first protective seat and the second protective seat. The two ends of the coupling are respectively connected to the rotating shaft and the drive shaft through a bevel gear set.

[0012] A further improvement is that the mounting base is provided with a support seat at the top, the support seat is provided with an assembly port at the top, and a rotating column two is rotatably provided in the assembly port. One end of the shaft of the rotating column two passes through the support seat and extends into the protective seat one to be connected to the rotating shaft for transmission. Several sets of bird-repelling plates are embedded in the outer wall of the rotating column two.

[0013] A further improvement is that the bird deterrent strip consists of three sets: a red reflector, a blue reflector, and a white reflector.

[0014] A further improvement is that brush heads are connected to both sides of the mounting block via support rods, and the cleaning end of the brush head is in contact with the outer edge of the large umbrella skirt.

[0015] The beneficial effects of this invention are as follows: By setting up a large umbrella skirt to shield the umbrella skirt assembly, this invention effectively prevents dirt from adhering to the surface of the umbrella skirt assembly. At the same time, a cleaning mechanism is configured to dynamically clean the large umbrella skirt. Under the action of external wind force, a non-powered wind ball drives the mounting base to perform a circular motion. During the movement, the brush continuously rubs the top wall of the large umbrella skirt to remove the attached dirt, avoiding the degradation of the insulation performance of the porcelain insulator due to dirt accumulation, which could damage the protected device. The drive mechanism intermittently pushes the ball when the mounting base rotates, causing it to strike the sound-generating mechanism. This triggers the sound-generating mechanism to produce a sound that frightens and repels birds that try to approach. At the same time, the vibration force generated by the ball's impact is transmitted to the brush through the mounting base, causing the brush to vibrate, enhancing the cleaning effect on the surface of the large umbrella skirt, and promoting the removal of dirt from the brush, reducing the contamination of the brush itself, thereby extending the maintenance cycle of the cleaning mechanism.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] Please see the attached Figure 1-3 A ceramic rod-shaped insulator with wind-powered dust removal capability includes an insulating rod 1, with connecting caps 4 at both ends of the insulating rod 1. The connecting caps 4 are used to install the ceramic rod-shaped insulator in the required position. The insulating rod 1 is provided with a skirt assembly, and the outer wall of the top connecting cap 4 is provided with a large skirt 6 with a diameter larger than that of the skirt assembly. The skirt assembly and the large skirt 6 are used to extend the creepage distance. The large skirt 6 has a larger diameter than the skirt assembly, which provides a shielding effect for the lower skirt assembly, making it difficult for dirt such as rain, snow, and bird droppings to adhere to the skirt assembly. The top surfaces of the large skirt 6 and the skirt assembly are both smooth, streamlined, inclined arc surfaces to guide rainwater and carry away dirt, improving the self-cleaning effect. A cleaning mechanism is provided above the large skirt 6 to clean it and remove dirt.

[0026] The cleaning mechanism includes a connecting bearing 7 rotatably mounted on the outer wall of the top connecting cap 4, several sets of mounting seats 10 connected to the connecting bearing 7 via connecting blocks 8, the mounting seats 10 being arranged in a circular array, the connecting blocks 8 being specifically fixed to the outer ring of the connecting bearing 7, the mounting seats 10 being inclined against the top wall of the large umbrella skirt 6, a brush 15 located at the bottom of the mounting seat 10 and against the top wall of the large umbrella skirt 6, and a non-powered air ball 9 rotatably mounted on the outer wall of the top connecting cap 4 and located above the connecting bearing 7. The outer wall of the non-powered air ball 9 is connected to the several sets of mounting seats 10 via brackets. Driven by external wind, the ball 9 drives the mounting base 10, brush 15, and connecting bearing 7 to move in a circular motion relative to the top connecting cap 4. When the wind blows across the cleaning mechanism, the unpowered ball 9 rotates. The unpowered ball 9 is a conventional component in this field and will not be described in detail here. When the unpowered ball 9 drives the mounting base 10 to move in a circular motion, the brush 15 rubs against the top wall of the large umbrella skirt 6 to remove dirt from the large umbrella skirt 6. In addition, the unpowered ball 9 also causes the air to flow vertically from bottom to top, which has a certain effect of blowing air downwards to sweep the surface of the large umbrella skirt 6, thus improving the cleaning quality.

[0027] Preferably, the umbrella skirt assembly of this embodiment includes several sets of first umbrella skirts 2 disposed on the outer wall of the insulating rod 1, and a second umbrella skirt 3 disposed between two adjacent sets of first umbrella skirts 2. The diameter of the first umbrella skirt 2 is larger than the diameter of the second umbrella skirt 3 and smaller than the diameter of the large umbrella skirt 6. By alternating the first umbrella skirts 2 and the second umbrella skirts 3 with different diameters, and by increasing the number of umbrella skirts, the overall creepage distance can be improved. By increasing the spacing between the first umbrella skirts 2 and the size of the diameter of the first umbrella skirt 2, the connection of dirt (such as ice) is prevented, and the anti-fouling performance is improved.

[0028] Preferably, the mounting base 10 of this embodiment has a channel 20, and a ball 21 is movably mounted in the channel 20. The ball 21 can preferably be a metal ball. A driving mechanism is provided in the mounting base 10 at the outer end of the channel 20, and a sound-generating mechanism is provided in the mounting base 10 at the inner end of the channel 20. The driving mechanism is used to intermittently push the ball 21 to strike the sound-generating mechanism when the mounting base 10 is in a circular motion. The sound-generating mechanism is used to generate a sound and transmit vibration force to the mounting base 10. With this arrangement, the sound-generating mechanism can scare away birds that try to approach, thus achieving the purpose of bird repellency. The ball 21 strikes the sound-generating mechanism and generates vibration force, which is transmitted to the mounting base 10. The mounting base 10 transmits the vibration force to the brush 15, causing the brush 15 to vibrate, improving the cleaning effect on the large umbrella skirt 6. At the same time, it is easy to shake off the dirt removed, reduce the contamination of the brush 15 itself, and extend its maintenance cycle. In addition, in winter, the vibration prevents ice crystals from accumulating between the bristles of the brush 15, which plays a certain role in preventing icing.

[0029] Example 2

[0030] Please see the attached Figure 3-6 Based on Embodiment 1, the driving mechanism of this embodiment includes a roller 12 rotatably disposed on the outer edge of the large umbrella skirt 6. When the mounting base 10 performs circular motion on the large umbrella skirt 6, the roller 12 performs circular motion along the outer edge of the large umbrella skirt 6. Under the action of friction, the roller 12 rotates. A mounting block 11 is disposed at one end of the mounting base 10. The mounting block 11 is a hollow structure with a movable cavity 1 opened in the mounting base 10 and located at the outer end of the channel 20. A top rod 17 is movably disposed in the movable cavity 1. It is T-shaped and includes a plate and a rod connecting the plate. One end of the top rod 17 extends into the channel 20, and the other end is connected to the inner wall of the movable cavity through an elastic member 18 (e.g., a spring). The shaft of the roller 12 extends into the mounting block 11 and is fitted with a toothed gear 16. A gear shaft meshes with one side of the toothed gear 16. The gear shaft includes a shaft and a gear fitted on the shaft and meshing with the toothed gear 16. A pull rope 19 is wound around the outer wall of the gear shaft. The other end of the pull rope 19 extends into the movable cavity and is connected to the top rod 17.

[0031] The working principle is as follows: Since the mounting base 10 is inclined on the large umbrella skirt 6, its channel 20 is inclined. The ball 21 in the channel 20 rolls to the top rod 17 under its own gravity. When the mounting base 10 is in circular motion, the roller 12 drives the toothed gear 16, the toothed gear 16 drives the gear shaft to rotate, and the gear shaft winds the rope 19 to pull the top rod 17 to move outward and squeeze the elastic member 18. When the toothless section on the toothed gear 16 corresponds to the gear shaft, the elastic member 18 drives the top rod 17 to reset and enter the channel 20 and hit the ball 21 in the channel 20. After being hit, the ball 21 moves to hit the sound-generating mechanism and produces a sound. At the same time, the mounting base 10 generates vibration force.

[0032] Preferably, the sound-generating mechanism in this embodiment includes a second movable cavity that is opened in the mounting base 10 and communicates with the inner end of the channel 20. The second movable cavity is provided with a rotating column 25. The outer wall of the rotating column 25 is provided with a sound-generating plate 22 for contacting the ball 21. The sound-generating plate 22 is preferably a metal plate. The ball 21 hits the metal plate to generate a sound, and the vibration force generated by the impact is transmitted to the rotating column 25. The rotating column 25 transmits the vibration force to the mounting base 10. In order to enhance the sound propagation effect, several sets of small holes communicating with the second movable cavity are provided on the outer wall of the mounting base 10, so that the sound waves radiate and diffuse outward through the small holes, thereby enhancing the bird deterrent warning effect.

[0033] Preferably, in this embodiment, the two sides of the mounting block 11 are respectively connected to the brush head 14 by the support rod. The cleaning end of the brush head 14 is in contact with the outer edge of the large umbrella skirt 6. When the mounting base 10 makes a circular motion, it also drives the brush head 14 to make a circular motion along the outer edge of the large umbrella skirt 6, thereby cleaning the outer edge of the large umbrella skirt 6 and ensuring the stable rotation of the roller 12.

[0034] Example 3

[0035] Please see the attached Figure 3-6 Based on Embodiment 2, the outer circumferential wall of the rotating column 25 in this embodiment has several sets of notches, each containing a sound-emitting plate 22. The thickness of each set of sound-emitting plates 22 is different; for example, there are three sets of sound-emitting plates 22: a thin plate, a standard-thickness plate, and a thick plate. When the sphere 21 impacts the sound-emitting plates 22 of different thicknesses, it produces different sounds. The thin plate typically produces a high-frequency sharp sound, the standard-thickness plate typically produces a mid-frequency resonant sound, and the thick plate typically produces a low-frequency booming sound. This non-periodic pitch variation caused by the thickness difference breaks the bird's adaptation to a single frequency, enhancing... The bird-repelling effect: The rotating column 25 is rotatably mounted in the movable cavity 2 via a rotating shaft. One end of the rotating shaft passes through the mounting base 10 and is equipped with a transmission component. The transmission component is used to intermittently drive the rotating shaft to rotate the rotating column 25 by a preset angle when the mounting base 10 performs circular motion, so that several sets of sound-emitting plates 22 correspond to the channel 20 in sequence, so that different sound-emitting plates 22 can cooperate with the ball 21. It should be noted that the bird-repelling mechanism and the transmission component are not triggered synchronously. That is, when the ball 21 is driven by the driving mechanism to move towards the rotating column 25, the rotating column 25 does not rotate, so as to ensure that the ball 21 hits the sound-emitting plate 22 on the rotating column 25 instead of the outer wall of the rotating column 25.

[0036] Preferably, the transmission component in this embodiment includes a first protective seat mounted on the mounting base 10 and movably sleeved on the outside of the rotating shaft, and a second protective seat mounted on the connecting block 8. A drive shaft is rotatably mounted inside the second protective seat. One end of the drive shaft passes through the second protective seat and is fitted with a transmission gear 24. A support ring 13 is provided inside the transmission gear 24. The support ring 13 is fixedly sleeved on the top connecting cap 4. The outer circumference of the support ring 13 is provided with several sets of arc-shaped racks for driving the transmission gear 24 to rotate. Under the action of the unpowered air ball 9, the mounting base 10 performs a circular motion relative to the top connecting cap 4, while the support ring 13 does not rotate. Therefore, the transmission gear 24 can intermittently mesh with the arc-shaped racks. Under the action of the arc-shaped racks, the transmission gear 24 drives the drive shaft to rotate. It should be noted that the number of arc-shaped racks is the same as the number of mounting seats 10, so that the transmission gears 24 on several sets of mounting seats 10 rotate synchronously. A coupling 23 is provided between the first protective seat and the second protective seat. This coupling 23 is, for example, a universal joint. The universal joint is a component that realizes the transmission of power at a variable angle. It is a conventional structure in this field and will not be described in detail here. The two ends of the coupling 23 are respectively connected to the rotating shaft and the drive shaft through a bevel gear set (two sets of meshing bevel gears). A bearing is also provided at the connection between the end of the coupling 23 and the first and second protective seats. When the drive shaft rotates, it drives the rotating shaft through the bevel gear set and the coupling 23, and then the rotating shaft drives the rotating column 25 to rotate, so as to switch the sound-emitting plate 22 corresponding to the channel 20.

[0037] Example 4

[0038] Please see the attached Figure 6 Based on embodiment 3, the mounting base 10 in this embodiment is fixedly provided with a bearing base 26 at the top. The bearing base 26 is provided with an assembly port at the top. A rotating column 27 is rotatably provided in the assembly port. One end of the shaft of the rotating column 27 passes through the bearing base 26 and extends into the protective base to be connected to the rotating shaft. The two can be connected by a bevel gear set. Several bird-repelling plates 5 are embedded in the outer wall of the rotating column 27. The bird-repelling plates 5 are, for example, reflective plates.

[0039] When there is no wind, the mounting base 10 cannot perform circular motion. In order to ensure the bird-repelling effect under such conditions, the bird-repelling plates 5 on the outer wall of the rotating column 27 are used to frighten and drive away birds that try to approach. When there is wind, when the drive shaft intermittently drives the rotating shaft to rotate, the rotating shaft also drives the rotating column 27 to rotate intermittently at a certain angle, so that several sets of bird-repelling plates 5 on the outer wall of the rotating column 27 are alternately exposed to the environment. The dynamic flipping process can effectively increase the birds' alertness and improve the bird-repelling effect of the bird-repelling plates 5.

[0040] Preferably, the bird deterrent sheet 5 in this embodiment consists of three sets: a red reflective sheet, a blue reflective sheet, and a white reflective sheet. Red, blue, and white are colors that birds are more afraid of, which will arouse birds' alertness. The different colored reflective sheets are exposed to the environment alternately, which can effectively avoid birds' adaptive fatigue to a single stimulus pattern and further improve the bird deterrent effect.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
