Description

Technical Field

[0001] This utility model relates to the technical field of insulator cleaning equipment, specifically to a high-voltage live-line insulating cleaning brush for cleaning horn-type insulators. Background Technology

[0002] Horn-type insulators (also known as pin insulators, named for their horn-like top structure) are mainly used in 10kV and below high-voltage transmission lines, installed on towers to support conductors and provide insulation. Due to their long-term outdoor exposure, they are susceptible to the accumulation of atmospheric dust, industrial pollutants (such as sulfides and particulate matter), salts, bird droppings, plant lint, and other impurities. In humid environments (such as rainy or foggy days), these pollutants can form a conductive layer, reducing the insulator's insulation strength. In severe cases, this can lead to "pollution flashover"—where contamination on the insulator surface causes insulation breakdown, resulting in a short circuit and affecting power supply safety.

[0003] Among related technologies, a search revealed a parallel synchronous double-brush insulator live-line cleaner, as disclosed in publication number CN208230334U. This cleaner includes a telescopic section, a rotating section, and a cleaning section connected sequentially. The telescopic section includes a sleeve, an inner rod, and a locking device. One end of the inner rod is connected to the rotating section, and the other end is fitted with a sleeve. The sleeve and the inner rod are fixed together by the locking device. The cleaning section includes a fixing plate and two cleaning brushes. One side of the fixing plate is connected to the rotating section, and the other side is connected to the cleaning brushes. This method solves the problem of live-line cleaning of insulators of different sizes and heights, and offers good insulation performance, a high safety factor, a simple structure, and is easy to disassemble and store.

[0004] The bristles on conventional cleaning brushes are mostly arranged horizontally. By rotating the bristles, the insulators are cleaned. However, due to the special shape of horn-shaped insulators, dust generally concentrates on the lower surface and the base of the insulator. Although the cleaning brush can be adjusted for cleaning, the horizontal design of the bristles means that some areas cannot be cleaned, resulting in poor cleaning performance for horn-shaped insulators. To solve the above problems, a high-voltage live-line insulator cleaning brush for cleaning horn-shaped insulators is proposed. Utility Model Content

[0005] In view of this, the present invention provides a high-voltage live-line insulation cleaning brush for cleaning horn-type insulators. The present invention uses a connecting shaft to drive the connecting disc to rotate the cross-shaped insert block, which in turn rotates the cross groove and the receiving block connected to the cross-shaped insert block, thereby causing the cylindrical core and the hemispherical core to rotate. This causes the first brush bristles on the arc surface of the hemispherical core to rotate, and the second brush bristles on the cylindrical core to rotate, thus enabling multi-angle cleaning of the horn-type insulator and improving the cleaning effect of the horn-type insulator.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-voltage live-line insulation cleaning brush for cleaning horn-type insulators, including a connecting shaft rotatably disposed at the top of the inner rod, and a brush core rotatably disposed at the upper end of the connecting shaft. The brush core includes a cylindrical core at the bottom and a hemispherical core at the top, which are thermally fused together. A plurality of first bristles are disposed along the spherical surface of the hemispherical core, and the first bristles are arranged vertically. A connecting block is disposed on the surface of the cylindrical core, and a plurality of second bristles are disposed on the connecting block, and the second bristles are arranged horizontally. The bottom of the cylindrical core is detachably connected to the connecting shaft.

[0007] Each first bristle has a movable opening at its base. The movable opening is used to maintain the range of motion of the first bristle during operation, thereby reducing the wear at the base of the first bristle during operation. Each movable opening is embedded in the hemispherical core.

[0008] Each movable port has a sealing head at its bottom. The sealing head is used to fix the first bristle and also to connect the first bristle to the hemispherical core. The sealing head is connected to the root of the corresponding first bristle.

[0009] Each of the second bristles has a groove at its base. The groove is used to install the connector, thereby connecting the second bristle to the connector block and then to the cylindrical core. The groove is embedded in its corresponding connector block.

[0010] Each groove is provided with a connector, which is used to connect the second bristle to the connecting block and connects the connector to the root of the corresponding second bristle.

[0011] The cylindrical core has an internal cavity to reduce the overall weight of the brush core. A receiving block is provided at the bottom of the cylindrical core, and a cross groove is provided in the middle of the receiving block to receive the cross insert.

[0012] A cross-shaped insert is provided at the bottom of the cross-shaped slot. The cross-shaped insert is used to insert into the cross-shaped slot, thereby sealing the connection between the connecting plate and the receiving block. A connecting plate is provided on the side of the cross-shaped insert away from the cylindrical core. The connecting plate is used to connect the receiving block and the bearing seat. A bearing seat is provided in the middle of the side of the connecting plate away from the cylindrical core. The bearing seat is used to connect the connecting plate and the connecting shaft. When the connecting shaft rotates, the connecting plate rotates synchronously, thereby driving the cylindrical core connected to the cross-shaped insert to rotate. The bearing seat and the connecting shaft are rotatably connected.

[0013] Each of the four sides of the connecting plate has a threaded hole for installing bolts. The bolts are made of insulating material. The connecting plate and the receiving block are fixedly connected by the bolts through the threaded holes. The threaded holes pass through the connecting plate and are embedded in the receiving block.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. The connecting shaft causes the connecting disc to rotate the cross-shaped insert, which in turn causes the cross groove and receiving block connected to the cross-shaped insert to rotate, which in turn causes the cylindrical core and hemispherical core to rotate, which in turn causes the first brush on the arc surface of the hemispherical core to rotate, and the second brush on the cylindrical core to rotate, thus enabling multi-angle cleaning of the horn-type insulator and improving the cleaning effect of the horn-type insulator.

[0016] 2. The movable opening is used to maintain the range of motion of the first brush bristles during operation, thereby reducing the wear at the root of the first brush bristles during operation and thus improving the service life of the component.

[0017] 3. The cavity is used to reduce the overall weight of the brush core, thereby reducing the weight of the entire cleaning device and reducing the difficulty of operation for the operator. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a high-voltage live-line insulating cleaning brush for cleaning horn-type insulators, including a connecting shaft 101 rotatably disposed at the top of the inner rod 100, and a brush core 200 rotatably disposed at the upper end of the connecting shaft 101. The brush core 200 includes a cylindrical core 201 at the bottom and a hemispherical core 202 at the top. The cylindrical core 201 and the hemispherical core 202 are thermally fused together. Both the cylindrical core 201 and the hemispherical core 202 are made of insulating material. A plurality of first bristles 300 are disposed along the spherical surface of the hemispherical core 202. The first bristles 300 disposed on the spherical surface facilitate the operator's rotation angle for cleaning the horn-type insulators. The lower surface of the insulator is cleaned. Both the first bristle 300 and the second bristle 401 are made of insulating material. The first bristle 300 is vertically arranged. A connecting block 400 is provided on the surface of the cylindrical core 201. The connecting block 400 is used to connect the second bristle 401 to the cylindrical core 201. Several second bristles 401 are provided on the connecting block 400. The second bristles 401 are used to clean the connecting part at the bottom of the horn-shaped insulator. The second bristles 401 are horizontally arranged. The bottom of the cylindrical core 201 is detachably connected to the connecting shaft 101. The detachable design facilitates the replacement of damaged brush cores 200 in the future.

[0025] In use, the connecting shaft 101 causes the connecting disc 500 to rotate the cross-shaped insert 206, which in turn causes the cross groove 402 and the receiving block 204 connected to the cross-shaped insert 206 to rotate, thereby causing the cylindrical core 201 and the hemispherical core 202 to rotate, which in turn causes the first bristles 300 on the arc surface of the hemispherical core 202 to rotate, and the second bristles 401 on the cylindrical core 201 to rotate, thus enabling multi-angle cleaning of the horn-type insulator and improving the cleaning effect of the horn-type insulator.

[0026] This embodiment provides a high-voltage live-line insulation cleaning brush for cleaning horn-type insulators.

[0027] like Figure 2 , 3 As shown in Figure 4: Each first bristle 300 has a movable opening 301 at its root. The movable opening 301 is used to maintain the range of motion of the first bristle 300 during operation, thereby reducing the wear at the root of the first bristle 300 during operation. Each movable opening 301 is embedded in the hemispherical core 202. Each movable opening 301 has a sealing head 302 at its bottom. The sealing head 302 is used to fix the first bristle 300 and also to connect the first bristle 300 to the hemispherical core 202. The sealing head 302 is connected to the root of its corresponding first bristle 300. The first bristle 300 and the sealing head 302 are heat-fused together. The sealing head 302 and the hemispherical core 202 are heat-fused together.

[0028] Its effect is that the movable opening 301 is used to maintain the range of motion of the first bristles 300 during operation, thereby reducing the wear at the root of the first bristles 300 during operation and thus improving the service life of the component.

[0029] like Figure 1 , 2 As shown in Figures 3 and 4: Each of the second bristles 401 has a groove 402 at its root. The groove 402 is used to install the connector 403, thereby connecting the second bristles 401 to the connecting block 400 and then to the cylindrical core 201. Each groove 402 is embedded in its corresponding connecting block 400. Each groove 402 has a connector 403. The connector 403 is glued to the connecting block 400. The connector 403 is used to glue the second bristles 401 together. The connector 403 is used to connect the second bristles 401 to the connecting block 400. The connector 403 is connected to the root of its corresponding second bristle 401.

[0030] Its effect is as follows: the groove 402 is used to install the connector 403, thereby connecting the second bristle 401 to the connecting block 400, and then connecting the second bristle 401 to the cylindrical core 201. The connector 403 is used to connect the second bristle 401 to the connecting block 400.

[0031] like Figure 3 As shown: The cylindrical core 201 has a cavity 203 inside, which is used to reduce the overall weight of the brush core 200. The bottom of the cylindrical core 201 is provided with a receiving block 204, which is heat-fused to the cylindrical core 201. The receiving block 204 is used to open a cross groove 205, which is embedded in the middle of the receiving block 204. The cross groove 205 is provided in the middle of the receiving block 204, which is used to receive the cross insert 206. The cross groove 205 and the cross insert 206 are tightly fitted.

[0032] Its effect is that the cavity 203 is used to reduce the overall weight of the brush core 200, thereby reducing the weight of the entire cleaning device and reducing the difficulty of operation for the operator.

[0033] like Figure 3 , 4As shown: A cross-shaped insert 206, made of insulating material, is provided at the bottom of the cross-shaped slot 205 to seal the connecting plate 500 and the receiving block 204. A connecting plate 500, also made of insulating material, is provided on the side of the cross-shaped insert 206 away from the cylindrical core 201. The connecting plate 500 and the cross-shaped insert 205 can be heat-fused together. The connecting plate 500 is used to seal the receiving block 204. 4. A bearing seat 102 is provided in the middle of the side of the connecting plate 500 away from the cylindrical core 201. The bearing seat 102 and the connecting plate 500 can be fixed by an insulating bolt. The bearing seat 102 is used to connect the connecting plate 500 and the connecting shaft 101. When the connecting shaft 101 rotates, the connecting plate 500 rotates synchronously, thereby driving the cylindrical core 201 connected to the cross plug 206 to rotate. The bearing seat 102 is rotatably connected to the connecting shaft 101.

[0034] Its effect is as follows: the cross-shaped insert 206 is used to insert into the cross-shaped slot 205, thereby sealing the connection between the connecting plate 500 and the receiving block 204. The connecting plate 500 is used to connect the receiving block 204 and the bearing seat 102. The bearing seat 102 is used to connect the connecting plate 500 and the connecting shaft 101. Thus, when the connecting shaft 101 rotates, the connecting plate 500 rotates synchronously, thereby driving the cylindrical core 201 connected to the cross-shaped insert 206 to rotate.

[0035] like Figure 4 As shown: A threaded hole 501 is provided on all four sides of the connecting plate 500. The threaded hole 501 is used to install bolts. The bolts are made of insulating material. The connecting plate 500 and the receiving block 204 are fixedly connected by the bolts through the threaded hole 501. The threaded hole 501 passes through the connecting plate 500 and is embedded in the receiving block 204.

[0036] Its effect is that the connecting plate 500 and the receiving block 204 are fixedly connected by bolts through the threaded hole 501, thereby connecting the bearing seat 102 and the cylindrical core 201.

[0037] Working principle: The rotation of the connecting shaft 101 drives the connecting disc 500 connected to the connecting shaft 101 to rotate the cross-shaped insert 206. This causes the cross groove 402 and the receiving block 204 connected to the cross-shaped insert 206 to rotate, which in turn causes the cylindrical core 201 and the hemispherical core 202 to rotate. This causes the first bristles 300 on the arc surface of the hemispherical core 202 to rotate, and the second bristles 401 on the cylindrical core 201 to rotate. This allows for multi-angle cleaning of the horn-type insulator, improving the cleaning effect of the horn-type insulator.

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
