Description

Technical Field

[0001] This utility model belongs to the field of capacitor sleeve technology, and in particular relates to a cleaning device for capacitor sleeves. Background Technology

[0002] Maintaining capacitor bushings involves a complex process of cleaning the accumulated impurities and dust from their inner cavities. Traditionally, this process has been done manually by operators using specialized cleaning equipment, which is not only time-consuming and physically demanding but also hinders overall work efficiency.

[0003] While using electric brushes simplifies the cleaning process and reduces manual labor to some extent, the brush surface often accumulates a large amount of fine dust and impurities after each cleaning cycle. If these residues are not thoroughly removed, they will be carried into the new casing with each subsequent use, potentially causing secondary contamination, affecting the consistency of cleaning results, and even posing an unnecessary risk of scratches or contamination to the delicate inner surfaces. Therefore, even though electric cleaning increases the speed of a single operation, it introduces potential quality risks for continuous, batch cleaning tasks.

[0004] Chinese patent discloses a novel capacitor sleeve cleaning device (authorization announcement number CN202570688U). The patented technology includes a motor installed inside the front end of the handle, a linkage shaft fixed to the rear end of the motor shaft, a cleaning disc fixed on the linkage shaft perpendicular to the axis and evenly arranged, small holes evenly distributed on the side wall of the linkage shaft, a compressed air pipe inside the handle connected to the linkage shaft, a fixing circular groove opened inward at the front end of the fixing arm, a uniformly long groove opened on the rear side wall of the fixing arm, and an "L"-shaped groove opened on the front side wall of the handle, one of the long grooves engaging with the protruding edge of the groove, so that the fixing arm is fixed on the handle.

[0005] However, the aforementioned patented solutions still fail to completely resolve the pain points of existing technologies in actual capacitor bushing cleaning operations: In the process of cleaning impurities and dust from the inner cavity of the capacitor bushing, relying on traditional manual cleaning devices remains time-consuming and physically demanding, making it difficult to improve overall work efficiency; even when using electric brushes to simplify the operation, a large amount of impurities and dust easily adheres to the brush surface after cleaning. If not treated promptly, these residues will directly affect the subsequent cleaning effect of the bushing and may even cause secondary pollution. Therefore, those skilled in the art urgently need to develop a new type of capacitor bushing cleaning device to effectively solve the technical problems mentioned in the background art.

[0016] Furthermore, a base plate is fixed to the lower end of the support plate.

[0017] Compared with existing technologies, the capacitor sleeve cleaning device of this utility model has the following advantages: When cleaning the inner cavity of a capacitor sleeve, this invention involves inserting a brush roller into the sleeve, starting the motor to drive gear two, and simultaneously rotating the cylinder and brush roller. The brush roller cleans the inner cavity of the capacitor sleeve.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Please see Figures 1 to 9 The embodiments provided by this utility model are as follows: Example: A cleaning device for capacitor bushings, comprising: A support plate 7 is provided, on which a cylinder 13 is detachably mounted. A gear 2 9 is mounted at the end of the cylinder 13. A gear 1 8 is rotatably mounted at the end of the support plate 7, and the gear 1 8 and the gear 2 9 are meshed together. A brush roller 25 is detachably mounted at the end of the cylinder 13 away from the gear 2 9. The meshing transmission between the gear 1 8 and the gear 2 9 can drive the cylinder 13 to rotate, thereby driving the brush roller 25 to rotate, which is used to clean the capacitor sleeve by driving the brush roller 25. A ring 2 15 is installed at the end of the support plate 7 away from the gear 1 8. A circular shell 5 is detachably installed on the ring 2 15. The brush roller 25 extends into the inner cavity of the circular shell 5, and a scraper 23 is provided on the inner wall of the circular shell 5 for cleaning the brush roller 25.

[0024] In the example of this application, the support plate 7 serves as the basic support component of the entire device, providing a stable mounting carrier for other core components. Its detachable cylinder 13 not only facilitates later maintenance and replacement of components but also forms a key node for power transmission through its fixed connection with gear 9. When gear 8 and gear 9 mesh and transmit power, power is smoothly transmitted to the cylinder 13, causing it to rotate stably, which in turn drives the detachably mounted brush roller 25 at its end to rotate. During the cleaning process, the rotating brush roller 25 can fully contact the capacitor sleeve, and through the friction of the bristles, efficiently removes dust, oil, and other impurities from inside the sleeve, ensuring the sleeve remains clean and guaranteeing the normal operation of the capacitor. Meanwhile, to prevent the brush roller 25 from reducing cleaning efficiency due to excessive impurities during the cleaning process, a self-cleaning function is provided. The support plate 7, located away from the ring 15 mounted at the end of the gear 8, provides a stable mounting base for the circular shell 5. The circular shell 5 is also detachable, facilitating subsequent cleaning and maintenance of its internal components. After the brush roller 25 extends into the inner cavity of the circular shell 5, the scraper 23 on the inner wall of the circular shell 5 can fully contact the bristles of the brush roller 25 during its continuous rotation, scraping away impurities adhering to the bristles. This keeps the brush roller 25 clean at all times, ensuring that its cleaning effect on the sleeve does not decrease due to impurity accumulation, thus achieving continuous and stable cleaning.

[0025] Furthermore, a ring 11 is attached to the end of the support plate 7, and the support plate 7 and the ring 11 are connected by bolts 28. A bearing 27 is installed inside the ring 11, and the end of the cylinder 13 passes through the bearing 27, and the cylinder 13 is rotatably connected to the bearing 27.

[0026] As a preferred example of this utility model, the ring 11 attached to the end of the support plate 7 is securely connected to the support plate 7 by bolts 28. This not only facilitates the assembly and disassembly of the ring 11, but also allows for adjustment of the ring 11's installation position according to actual needs, improving the adaptability of the structure. The bearing 27 installed inside the ring 11 effectively reduces the frictional resistance when the cylinder 13 rotates. When the end of the cylinder 13 passes through the bearing 27 and is rotatably connected to it, the cylinder 13 can achieve smooth and stable rotation under the action of the bearing 27, avoiding the cylinder 13 from jamming due to excessive friction, which would affect the cleaning effect of the brush roller 25.

[0027] Furthermore, a motor 6 is installed at the end of the support plate 7 away from the gear 8, and the drive end of the motor 6 is connected to the gear 8.

[0028] As a preferred example of this utility model, the motor 6, mounted on the support plate 7 away from the end of gear 8, serves as a dedicated power output component, providing continuous and stable power to gear 8. When motor 6 starts, its drive end directly connects to gear 8 and drives it to rotate. Through the meshing of gear 8 and gear 9, power is transmitted to cylinder 13, ultimately driving brush roller 25 to rotate at a stable speed for cleaning. Compared to manual drive, motor 6 ensures that gear 8 maintains a uniform speed, preventing fluctuations in brush roller 25 speed due to uneven manual operation or fatigue, thus guaranteeing consistent cleaning results. Simultaneously, automated power drive significantly reduces manual labor intensity; operators only need to control the start and stop of motor 6 to complete the cleaning work, improving efficiency, especially suitable for large-scale, long-term capacitor sleeve cleaning scenarios.

[0029] Furthermore, a through hole 16 is provided at the end of the support plate 7, and the end of the cylinder 13 away from the gear 9 passes through the through hole 16.

[0030] As a preferred example of this utility model, the position of the through hole 16 matches the installation path of the cylinder 13. When the end of the cylinder 13 away from the gear 9 passes through the through hole 16, the inner wall of the through hole 16 provides good support and guidance for the cylinder 13, effectively limiting the radial displacement of the cylinder 13 during rotation. This prevents the cylinder 13 from wobbling or tilting due to uneven force, thereby preventing the brush roller 25 from shifting its contact position with the sleeve and ensuring that the brush roller 25 maintains uniform contact with the inside of the sleeve, achieving comprehensive and thorough cleaning. In addition, the presence of the through hole 16 provides a clear positioning reference for the installation of the cylinder 13, facilitating the operator to quickly and accurately assemble the cylinder 13 with other components, thus improving the assembly efficiency of the device.

[0031] Furthermore, a threaded groove 26 is provided at the end of the cylinder 13 away from the gear 29, and a threaded post 29 is installed at the end of the brush roller 25, with the threaded post 29 extending into the threaded groove 26 for threaded connection.

[0032] As a preferred example of this utility model, the threaded groove 26 at the end of the cylinder 13 furthest from the gear 9 is adapted to the threaded post 29 installed at the end of the brush roller 25. The threaded post 29 extends into the threaded groove 26 and forms a threaded connection, thus achieving a stable fixation between the brush roller 25 and the cylinder 13. When the brush roller 25 experiences bristle wear or deformation after long-term use, or when excessive impurities that are difficult to remove by the scraper 23 adhere during cleaning, the operator only needs to rotate the brush roller 25 to unscrew the threaded post 29 from the threaded groove 26, allowing for quick removal of the brush roller 25 for replacement or deep cleaning without disassembling other complex components. This detachable structure not only simplifies and facilitates operation but also prevents the entire device from becoming unusable due to damage to the brush roller 25, reducing maintenance costs. It also facilitates the replacement of brush rollers 25 with suitable ones of different specifications and materials, improving the versatility of the device.

[0033] Furthermore, the end of the second annular ring 15 is provided with an annular threaded groove 14, and the end of the circular shell 5 is provided with a threaded ring 24, which extends into the annular threaded groove 14 for threaded connection.

[0034] As a preferred example of this utility model, the threaded connection structure between the second ring 15 and the circular shell 5 enables convenient disassembly and assembly of the circular shell 5, greatly facilitating the maintenance and cleaning of the scraper 23 inside the circular shell 5 and the inspection of the circular shell 5 itself. Simultaneously, it ensures the installation stability of the circular shell 5 during operation and guarantees the reliable realization of the self-cleaning function. The annular threaded groove 14 at the end of the second ring 15 forms a threaded engagement with the threaded ring 24 installed at the end of the circular shell 5. When the threaded ring 24 extends into the annular threaded groove 14 and is tightened, it allows the circular shell 5 to be tightly connected to the second ring 15, thereby achieving a stable installation of the circular shell 5 on the support plate 7. This prevents the circular shell 5 from loosening or shifting during the rotation and cleaning of the brush roller 25 and the scraping of impurities by the scraper 23, ensuring that the scraper 23 always maintains good contact with the brush roller 25 and stably performs its self-cleaning function. When it is necessary to clean, maintain or replace the scraper 23 inside the circular shell 5, or to clean the inner cavity of the circular shell 5, simply rotate the circular shell 5 in the opposite direction so that the threaded ring 24 is unscrewed from the annular threaded groove 14, and the circular shell 5 can be easily removed. The operation is simple and quick, which greatly reduces the maintenance difficulty of the internal components of the device and improves the maintenance efficiency.

[0035] Furthermore, a circular groove 12 is provided at the end of the circular shell 5, and multiple scrapers 23 arranged in a ring array are fixed in the circular groove 12.

[0036] As a preferred example of this utility model, the circular groove 12 provides installation space for the scraper 23, effectively positioning and fixing it to prevent displacement or detachment during operation. Multiple scrapers 23 are fixed within the circular groove 12 in a ring array, ensuring that the brush roller 25, after extending into the groove 12, makes full contact with the scrapers 23 at all angles of its surface. During the rotation of the brush roller 25, each scraper 23 scrapes its corresponding bristle area, removing impurities from different directions and positions. Compared to single or asymmetrically distributed scrapers 23, the ring array structure effectively avoids cleaning dead zones, ensuring thorough removal of impurities from the surface of the brush roller 25 and maintaining its cleanliness, thereby guaranteeing effective cleaning of the capacitor bushing.

[0037] Furthermore, brackets 22 are fixed at the front and rear of the lower end of the circular shell 5, respectively. The end of the bracket 22 is provided with a slot 20, and a plug plate 19 is inserted into the slot 20. A connecting frame 4 is installed on the plug plate 19, and a collection box 3 is fixed at the lower end of the connecting frame 4.

[0038] As a preferred example of this utility model, a bracket 22 is installed at the lower end of the circular shell 5, and the collection box 3 is installed in conjunction with the insert plate 19 and the connecting frame 4, forming an impurity collection structure. This structure not only effectively collects the impurities scraped off by the scraper 23, preventing impurities from scattering and polluting the environment, but also allows for easy disassembly and assembly of the collection box 3, facilitating subsequent cleaning of the collected impurities. The bracket 22, fixed at the front and rear of the lower end of the circular shell 5, provides a stable support foundation for the installation of the collection box 3. The slot 20 at the end of the bracket 22 is compatible with the insert plate 19. By inserting the insert plate 19 into the slot 20, the connecting frame 4 can be quickly connected to the bracket 22, thereby fixing the collection box 3 under the circular shell 5. The plug-in connection structure is simple to operate; the operator only needs to insert or remove the insert plate 19 from the slot 20 to complete the installation or disassembly of the collection box 3. After a certain amount of impurities have been collected in the collection box 3, it can be easily removed for cleaning. After cleaning, it can be reinstalled in its original position to ensure the continuity of the impurity collection process.

[0039] Furthermore, a through groove 21 is provided at the lower end of the circular shell 5, and the through groove 21 is connected to the circular groove 12. An installation frame 18 is installed in the inner cavity of the collection box 3, and a filter screen 17 is fixed inside the installation frame 18. A pipe 2 is provided at the lower end of the collection box 3, and a hose 1 is connected to the lower end of the pipe 2. The hose 1 is connected to an external negative pressure power source.

[0040] As a preferred example of this utility model, the through groove 21 at the lower end of the circular shell 5 communicates with the circular groove 12, and the through groove 21 communicates with the inner cavity of the collection box 3 through the top opening of the collection box 3, so that the impurities scraped by the scraper 23 can fall smoothly into the collection box 3 below through the through groove 21, avoiding the accumulation of impurities in the circular shell 5. The mounting bracket 18 installed in the inner cavity of the collection box 3 provides a stable mounting carrier for the filter screen 17, which can filter and separate the impurities falling into the collection box 3, intercepting the impurities above the filter screen 17. At the same time, the pipe 2 at the lower end of the collection box 3 is connected to the hose 1, and the hose 1 is connected to an external negative pressure power source. When the external negative pressure power source is started, a negative pressure environment is formed in the collection box 3, and the impurities in the circular groove 12 are actively sucked into the collection box 3 through the through groove 21, which greatly improves the efficiency and thoroughness of impurity collection and avoids the residue of impurities in the circular groove 12.

[0041] Furthermore, a base plate 10 is fixed to the lower end of the support plate 7, and multiple mounting holes are provided on the upper end of the base plate 10.

[0042] As a preferred example of this utility model, the base plate 10 is fixedly connected to the support plate 7, which can stably support the support plate 7 and all components installed on it, increasing the contact area between the device and the mounting surface and improving the overall stability of the device. Multiple mounting holes on the upper end of the base plate 10 can be used with screws to fix the device to the ground, workbench, or other designated mounting locations. Operators can select a suitable mounting location according to actual operational needs and securely fix the device through the mounting holes, preventing displacement or shaking of the device during the operation of the motor 6 and the rotation of the brush roller 25 for cleaning. This ensures that the brush roller 25 can stably and accurately contact the sleeve for cleaning operations, guaranteeing the reliability of the cleaning effect.

[0043] In this embodiment, when cleaning the inner cavity of the capacitor bushing is required, the operator first needs to securely connect the brush roller 25 to the threaded groove 26 at the end of the cylinder 13 via the threaded post 29 at its end, according to the actual condition of the capacitor bushing, to ensure that the brush roller 25 will not loosen or fall off during rotation. Then, the brush roller 25 is slowly inserted into the inner cavity of the capacitor bushing, ensuring that the brush roller 25 can fully contact the inner wall of the bushing. At this time, the motor 6, installed on the support plate 7 at the end furthest from gear 8, is started. The drive end of the motor 6 directly drives gear 8 to start rotating. Since gear 8 meshes with gear 9 installed at the end of cylinder 13, the rotational power of gear 8 is transmitted to gear 9, thereby driving cylinder 13 to rotate synchronously. The bearing 27, which is installed through ring 11 at the end of cylinder 13, and ring 11, which is securely connected to the support plate 7 by bolts 28, can effectively reduce the frictional resistance when cylinder 13 rotates, ensuring that cylinder 13 rotates smoothly and stably. As the brush roller 25 rotates continuously, the bristles on its surface will generate sufficient friction with the inner wall of the capacitor bushing, effectively removing impurities such as dust, oil, and metal shavings attached to the inner wall, ensuring that the inner cavity of the capacitor bushing is restored to a clean state, and providing a guarantee for the safe and stable operation of the capacitor.

[0044] After the inner cavity of the capacitor bushing is cleaned, when it is necessary to clean the impurities and dust adhering to the surface of the brush roller 25, the operator must first align the threaded ring 24 installed at the end of the round shell 5 with the annular threaded groove 14 opened at the end of the second ring 15 installed at the end of the support plate 7, and insert the threaded ring 24 into the annular threaded groove 14 for threaded connection until the round shell 5 and the second ring 15 fit tightly together, ensuring that the round shell 5 will not loosen or shift during the subsequent cleaning process. During this process, the brush roller 25 will simultaneously extend into the annular groove 12 opened at the end of the round shell 5, and multiple scrapers 23 arranged in a ring array are fixed in the annular groove 12. The scrapers 23 can contact the bristles on the surface of the brush roller 25 from different angles and positions, preparing the structure for subsequent impurity cleaning.

[0045] Subsequently, motor 6 is restarted, driving gear 8 and gear 9 to rotate cylinder 13 and brush roller 25. During the rotation of brush roller 25, scraper 23 in the groove 12 continuously contacts and interacts with the bristles, separating impurities and dust adhering to the surface of brush roller 25 from the bristles through tapping and scraping, thus preventing impurities and dust from remaining on the bristles for a long time and affecting the subsequent cleaning effect of brush roller 25. At the same time, the external negative pressure power source connected to the hose 1 at the lower end of the pipe 2 connected to the lower end of the collection box 3 needs to be activated. Under the action of the negative pressure power source, a stable negative pressure environment will be formed in the inner cavity of the collection box 3. The lower end of the circular shell 5 is provided with a through groove 21 that communicates with the circular groove 12. The negative pressure will act on the circular groove 12 through the through groove 21, so that the impurities and dust separated by the scraper 23 can be smoothly sucked into the collection box 3, preventing impurities and dust from accumulating in the circular groove 12 or falling into the surrounding environment. When impurities and dust enter the collection box 3, the filter 17 fixed inside the mounting bracket 18 installed in the inner cavity of the collection box 3 will intercept and filter the impurities and dust, blocking them above the filter 17 for collection. The collection box 3 is connected to the slot 20 at the end of the support 22 at the lower end of the cylindrical shell 5 via the insert plate 19 on the connecting bracket 4. After a certain amount of impurities and dust has been collected in the collection box 3, the operator can pull the insert plate 19 out of the slot 20, remove the collection box 3, and clean the internal impurities and dust. After cleaning, the collection box 3 is reinstalled in its original position to ensure that the self-cleaning and impurity collection functions of the device can operate continuously and stably. This achieves the effect of improving the cleaning efficiency of capacitor bushings, saving time and effort, and also enabling the self-cleaning of the brush roller 25 used for cleaning capacitor bushings.

[0046] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
