Description

Technical Field

[0001] The invention relates to the technical field of insulators, and in particular to an insulator protection device. Background Art

[0002] Insulators, as the name implies, are devices used to isolate the conductive part of an electrical device from the grounded part or another conductive part to keep it electrically insulated. They are usually made of insulating materials, such as ceramics, glass, composite materials, etc., and can withstand a variety of tests such as voltage, mechanical stress, and harsh environments. The most basic function of insulators is to provide electrical insulation to ensure safe and stable power transmission;

[0003] During the long-term use of insulator materials, birds may excrete bird droppings on the surface of the insulator when they perch on the crossarms and hardware just above the insulators. These impurities will reduce the withstand voltage of the insulator when exposed to moisture. After the impurities combine with moisture, a discharge circuit will be formed on the surface of the insulator, increasing the leakage current. When the leakage current reaches a certain value, it will cause surface breakdown discharge, i.e. flashover, causing damage to the insulator. Therefore, an insulator protection device is needed to clean the impurities on the surface of the insulator. Summary of the invention

[0004] The purpose of the present invention is to propose an insulator protection device to solve the problem that when dirt combines with moisture, a discharge circuit is formed on the surface of the insulator, which increases the leakage current. When the leakage current reaches a certain value, it will cause surface breakdown discharge, i.e. flashover, causing insulator damage.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: an insulator protection device, including an insulator mechanism, an insulator string protection mechanism and an adjustment mechanism, wherein the insulator mechanism includes a support column, and an insulator is slidably installed on the outside of the support column; the insulator string protection mechanism includes a clamping plate arranged at both ends of the support column, a connecting rod and a wind gathering plate clamped between the two clamping plates are fixedly installed between the two clamping plates, a connecting plate is sleeved on the outside of the connecting rod, and a scraper 1 and a scraper 2 matching the insulator are fixed on one end of the connecting plate; a buffer component is arranged on one side of the clamping plate, and the buffer component includes a sleeve connected to the clamping plate through a bearing and slidably inserted at both ends of the support column;

[0006] As a further description of an insulator protection device of the above technology:

[0007] The adjusting mechanism comprises a transmission plate slidably mounted on a wind gathering plate, the transmission plate being provided with a guide rail matching with a connecting plate, the transmission plate slidingly adjusts the distance between a number of connecting plates and simultaneously realizes the equidistant adjustment between a number of insulators, the wind gathering plate is rotated by the wind force, so that the two scrapers rotate around the insulator, thereby limiting the insulator and cleaning its surface simultaneously.

[0008] As a further description of an insulator protection device of the above technology:

[0009] The two ends of the connecting rod cooperate with nuts to limit the clamping plate, and the wind gathering plate is used to limit the two clamping plates at the two ends of the supporting column.

[0010] The regulating mechanism comprises a slide slot 1 provided on the wind gathering plate, a threaded rod is rotatably installed inside the slide slot 1, and a slider 1 matching the slide slot 1 is threadedly connected to the outside of the threaded rod. The distances between the connecting plates in two adjacent guide rails are equal.

[0011] As a further description of an insulator protection device of the above technology:

[0012] The connecting plate is a hollow shell structure, located between the two scrapers, and a liquid inlet groove is provided on the connecting plate, and a liquid outlet groove extending into the guide rail is provided at one end of the connecting plate away from the scraper. The buffer assembly also includes a slider 2 fixed inside the sleeve, and a slide groove 2 matching the slider 2 is provided on the support column.

[0013] As a further description of an insulator protection device of the above technology:

[0014] A return spring is fixedly mounted on one end of the slide block 2, and an end of the return spring away from the slide block 2 elastically moves in the slide groove 2.

[0015] In summary, due to the use of the above-mentioned technology, the insulator protection device of the present invention has the following beneficial effects:

[0016] When the insulator is used in a vertical state, by installing the insulator string protection mechanism on the support column and the periphery of the insulator, when the wind gathering plate in the insulator string protection mechanism is blown by the wind, the wind gathering plate will drive the card plate to rotate, and at the same time drive the scraper 1 and the scraper 2 to clean the side and bottom of the insulator string at the same time, so as to avoid dirt remaining on the insulator and avoid damage to the insulator caused by flashover, so as to achieve protection of the insulator. At the same time, since the scraper 1 and the scraper 2 are designed at an acute angle, when the adjustment mechanism is adjusted, the transmission plate will slide on one side of the wind gathering plate, so that the distance between several connecting plates is adjusted at the same time, so that each group of scrapers drives each insulator to adjust at the same time, so that the spacing between the insulators can adapt to different load voltage lines, avoid excessive electric field strength caused by too small insulator spacing, reduce discharge risks, and achieve protection of the insulator;

[0017] When the insulator is used in a horizontal state, the connecting plate in the insulator string protection mechanism plays a diversion effect, allowing rainwater on the insulator to flow out from the inside of the connecting plate through the guide rail, avoiding the transfer of rainwater between two adjacent insulators to cause flashover. At the same time, the buffer component is used to make an elastic connection between the clamping plate and the support column, so that when the insulator string is installed horizontally, it can avoid damage to the insulator caused by excessive tension at both ends, thereby playing a buffering effect.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the insulator protection device in the embodiments of the present invention. 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.

[0031] like Figure 1-Figure 8 As shown, the present invention provides: an insulator protection device, including an insulator mechanism 10, an insulator string protection mechanism 20 and an adjustment mechanism 30, the insulator mechanism 10 includes a support column 11, and an insulator 12 is slidably installed on the outside of the support column 11; the support column 11 is a structure for fixing the insulator 12 in the prior art, a group of limit bars are fixedly installed on the support column 11, and a limit groove matching the limit bar is opened inside the insulator 12, so that the insulator 12 can slide on the support column 11, so as to adjust the position of the insulator 12.

[0032] In further detail, the insulator string protection mechanism 20 includes a card plate 21 arranged at both ends of the support column 11, a connecting rod 22 and a wind gathering plate 23 clamped between the two card plates 21 are fixedly installed between the two card plates 21, a connecting plate 25 is sleeved on the outside of the connecting rod 22, and a scraper 1 26 and a scraper 26a matching the insulator 12 are fixed at one end of the connecting plate 25; the two ends of the connecting rod 22 cooperate with nuts to limit the card plate 21, and the wind gathering plate 23 is used to limit the two card plates 21 At both ends of the support column 11, the connecting rod 22 and the nut are threadedly connected, so when the two ends of the connecting rod 22 are inserted into the card plate 21, the cooperation between the connecting rod 22 and the nut can make the card plate 21 movably installed on the connecting rod 22. At this time, the wind gathering plate 23 is clamped between the two card plates 21, so that the card plate 21 and the wind gathering plate 23 and the connecting rod 22 are firmly fixed; wherein, the card plate 21, the connecting rod 22, and the wind gathering plate 23 are all made of hard plastic material, which has an insulating effect.

[0033] In further detail, a buffer assembly 24 is provided on one side of the card plate 21, and the buffer assembly 24 includes a sleeve 241 connected to the card plate 21 through a bearing and slidably inserted at both ends of the support column 11; the sleeve 241 is used to connect the wires to realize the installation of the insulator string; at the same time, the sleeve 241 is connected to the two ends of the support column 11, so that when the sleeve 241 is detached from the support column 11, the insulator 12 on the support column 11 is easy to disassemble, so that when a single insulator 12 is damaged, the insulator 12 can be replaced in time.

[0034] In further detail, the buffer assembly 24 also includes a slider 243 fixed inside the sleeve 241, and a slide groove 244 matching the slider 243 is provided on the support column 11. A reset spring 242 is fixedly installed at one end of the slider 243, and the end of the reset spring 242 away from the slider 243 elastically moves in the slide groove 244. The slide groove 244 provides a sliding space for the slider 243 to facilitate the sliding of the slider 243. The cooperation between the slide groove 244 and the slider 243 enables the sleeve 241 to be slidably inserted into the support column 11, so as to limit the position of the sleeve 241, so that the sleeve 241 will not rotate with the clamping plate 21; therefore, when the insulator 12 is used in a vertical state, by stringing the insulator together to prevent the insulator from rotating. The protection mechanism 20 is installed on the periphery of the support column 11 and the insulator 12. When the wind gathering plate 23 in the insulator string protection mechanism 20 is blown by wind, the wind gathering plate 23 will drive the clamping plate 21 to rotate. The clamping plate 21 is connected to the sleeve 241 through a bearing, and the sleeve 241 is limited on the support column 11, so that when the clamping plate 21 rotates, it drives the scraper 1 26 and the scraper 2 26a to clean the side and bottom of the insulator string at the same time, avoiding dirt from remaining on the insulator 12, avoiding damage to the insulator 12 caused by flashover, and protecting the insulator 12.

[0035] Among them, when the insulator 12 is used in a horizontal state, the elastic force provided by the return spring 242 in the buffer assembly 24 is used to elastically connect the clamping plate 21 and the support column 11, so that when the insulator string is installed horizontally, excessive tension at both ends can be avoided to cause damage to the insulator 12, thereby achieving a buffering effect and protecting the insulator 12.

[0036] like Figure 1-Figure 8 As shown, the adjustment mechanism 30 includes a transmission plate 27 slidably mounted on the wind gathering plate 23, and a guide rail 28 matching the connecting plate 25 is provided on the transmission plate 27. The transmission plate 27 slides to adjust the distance between a number of connecting plates 25 and simultaneously achieves equidistant adjustment between a number of insulators 12. The wind gathering plate 23 is rotated by the wind, so that the two scrapers rotate around the insulator 12, thereby limiting the insulator 12 and cleaning its surface at the same time.

[0037] In further detail, the adjustment mechanism 30 includes a slide groove 33 provided on the wind gathering plate 23, a threaded rod 31 is rotatably mounted inside the slide groove 33, and a slider 32 matching the slide groove 33 is threadedly connected to the outside of the threaded rod 31. The distances between the connecting plates 25 in two adjacent guide rails 28 are equal. The slide groove 33 provides a sliding space for the slider 32. Since the threaded rod 31 and the slider 32 are threadedly connected, when the threaded rod 31 rotates, an axial force will be generated on the slider 32, so that the slider 32 slides inside the slide groove 33. When the slider 32 slides inside the slide groove 33, the slider 32 will drive the transmission plate 27 to move in contact with the wind gathering plate 23. When the transmission plate 27 moves, the transmission plate 27 will drive the guide rail 28 to move, thereby moving the connecting plate 25 in the guide rail 28, so that the connecting plate 25 can slide on the outside of the connecting rod 22, thereby realizing the equidistant adjustment between the connecting plates 25, so that each group of scrapers drives each insulator 12 to adjust at the same time, so that the spacing between the insulators 12 can adapt to different load voltage lines, avoid excessive electric field strength caused by too small a spacing between the insulators 12, reduce the risk of discharge, and achieve protection for the insulators 12.

[0038] In further detail, the connecting plate 25 is a hollow shell structure, and a liquid inlet groove 29 is provided on the connecting plate 25 located between the two scrapers, and a liquid outlet groove extending into the guide rail 28 is provided at one end of the connecting plate 25 away from the scraper. The connecting plate 25 of the hollow shell structure can facilitate the flow of rainwater, and the connecting plate 25 in the insulator string protection mechanism 20 plays a guiding role, so that the rainwater on the insulator flows out from the inside of the connecting plate 25 through the guide rail 28, thereby avoiding the transfer of rainwater between two adjacent insulators 12 and causing flashover.

[0039] Working principle: When installing the insulator string protection mechanism 20, first insert the scraper on the insulator 12, then clamp the two clamping plates 21 to the wind gathering plate 23, and at the same time, insert the sleeve 241 at one end of the clamping plate 21 into the two ends of the support column 11 to realize the installation of the protection mechanism. When the insulator 12 is used in a vertical state, by installing the insulator string protection mechanism 20 on the support column 11 and the periphery of the insulator 12, when the wind gathering plate 23 in the insulator string protection mechanism 20 is blown by wind, the wind gathering plate 23 will drive the clamping plate 21 to rotate, the clamping plate 21 and the sleeve 241 are connected by a bearing, and the sleeve 241 is limited on the support column 11, so that when the clamping plate 21 rotates, it drives the scraper 1 26 and the scraper 2 26a to clean the sides and bottom of the insulator string at the same time, so as to avoid dirt remaining on the insulator 12 and avoid damage to the insulator 12 caused by flashover, so as to realize the protection of the insulator 12.

[0040] When the threaded rod 31 rotates, an axial force is generated on the slider 32, so that the slider 32 slides inside the slide groove 33. When the slider 32 slides inside the slide groove 33, the slider 32 drives the transmission plate 27 to move in contact with the wind gathering plate 23. When the transmission plate 27 moves, the transmission plate 27 drives the guide rail 28 to move, thereby moving the connecting plate 25 in the guide rail 28, so that the connecting plate 25 can slide on the outside of the connecting rod 22, thereby realizing the equidistant adjustment between the connecting plates 25, so that each group of scrapers drives each insulator 12 to adjust at the same time, so that the spacing of the insulators 12 can adapt to different load voltage lines, avoid excessive electric field strength caused by too small spacing between the insulators 12, reduce the risk of discharge, and achieve protection for the insulators 12.

[0041] When the insulator 12 is used in a horizontal state, the elastic force provided by the return spring 242 in the buffer assembly 24 is used to elastically connect the clamping plate 21 and the support column 11, so that when the insulator string is installed horizontally, the tension at both ends is prevented from being excessive, which may cause damage to the insulator 12, thereby achieving a buffering effect and protecting the insulator 12; at the same time, when the insulator 12 is used in a horizontal state, the connecting plate 25 in the insulator string protection mechanism 20 has a diversion effect, so that rainwater on the insulator 12 flows out from the inside of the connecting plate 25 through the guide rail 28, thereby avoiding the transfer of rainwater between two adjacent insulators 12 and causing flashover.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to an insulator protection device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
