Description

Technical Field

[0001] This application relates to the technical field of insulator cleaning equipment, and more particularly to a cleaning device for post insulators. Background Technology

[0002] Traditional insulator cleaning methods involve using aerial work platforms equipped with water pumps, spray guns, rags, and other standard cleaning equipment to clean each post insulator in the work area one by one. Besides requiring a large number of aerial work platforms, this also necessitates the deployment of vehicle commanders and dedicated safety supervisors. Furthermore, due to space limitations, some post insulators cannot be cleaned using conventional methods.

[0003] The prior art provides an insulator cleaning device, which reduces site restrictions and manpower use through a ring-shaped fixing method. It mainly includes a fixing frame, a spraying device, a limiting frame and a rotating mechanism. With their cooperation, it effectively solves the problems of incomplete insulator cleaning, low cleaning efficiency and poor cleaning effect.

[0004] However, there are still some shortcomings in the existing technology. When the ring-type cleaning device is used to clean the post insulator, it needs to climb and change different cleaning positions. The cleaning device will encounter insulator skirts of different sizes as the climbing height varies. Therefore, the existing insulator cleaning device does not have the ability to adapt to the post insulator cleaning device through climbing function. Summary of the Invention

[0017] In some modified embodiments of this application, the second transmission assembly includes synchronous pulleys arranged synchronously on the rotating shafts of each brush component, and a transmission belt sleeved on each synchronous pulley; the transmission belt engages with the output shaft of the second drive component.

[0018] In some modified embodiments of this application, the base is further provided with an arc-shaped rack structure and an arc-shaped guide groove that can cooperate with the rack structure; the base is slidably mounted on the circumferential body through the cooperation of the limiting post and the arc-shaped guide groove; the rack structure is connected to the motor component and fixes the motor component on the circumferential body, and is used to drive the base to slide along the extension direction of the arc-shaped guide groove through the motor component.

[0040] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough in its understanding and will fully convey the scope of the present application to those skilled in the art.

[0041] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0042] Currently, given the development of science and technology, energy applications are becoming increasingly widespread, including the vigorous promotion of electricity, indicating that electricity will receive greater demand and favor as its development progresses. Insulators are one of the core components in power transmission equipment. Insulators are devices installed between conductors at different potentials or between conductors and grounding components, capable of withstanding voltage and mechanical stress. They are a special type of insulation control and play a crucial role in power transmission and transformation projects. Insulators also require regular cleaning to reduce corrosion of the insulation layer, protect the anti-flashover layer, and prevent large-scale sudden power outages caused by pollution flashover or fog flashover.

[0043] The inventors of this application have discovered that existing technologies, in order to avoid consuming significant manpower and space resources, have proposed an insulator cleaning device that is fixed to the outer layer of the insulator in a circumferential manner, and then cleans it using nozzles and brushing components. However, this cleaning device requires climbing capabilities for some insulators, such as post insulators. Since the shed diameters of post insulators are not uniform, but vary in size (potentially gradually increasing or decreasing in diameter, or even randomly arranged), this creates a difficult problem to solve quickly in terms of the cleaning device's climbing ability. Ultimately, this still requires the combined efforts of manpower and lifting vehicles to continuously reposition the cleaning device, failing to fundamentally solve the technical problem of saving manpower and space resources.

[0044] Reference Figures 1 to 8 As shown in the embodiment of this application, a cleaning device for post insulators is proposed, which mainly includes a ring body 1, which has a cylindrical structure and is used to be sleeved on the post insulator; a cleaning mechanism 2, which is disposed on the outer edges of both ends of the ring body 1, for spraying and brushing the post insulator; and a walking mechanism 3, which is disposed on the inner wall of the ring body 1, so as to drive the ring body 1 to move along the height direction of the post insulator.

[0045] The walking mechanism 3 clamps the main body 1 onto the post insulator and can adapt the clamping size to compensate for the continuously changing diameter of the post insulator.

[0046] Specifically, in the technical solution adopted in this application, the cleaning device can be fitted onto the sheds on the outer surface of the post insulator through the encircling body 1. The encircling body 1 can be composed of an encircling frame formed by two fastening rings. The cleaning mechanism 2, which is set at both ends of the encircling body 1, performs spraying and brushing work, which can be accomplished by using a spray nozzle and a cleaning brush. Specifically, the cleaning mechanism 2 can be installed on the fastening rings of the encircling body 1. In order to realize the climbing function of the cleaning device, a walking structure is also installed on the inner side of the encircling body 1. The walking mechanism 3 can be installed on the connecting structure between the two fastening rings in the encircling body 1. The connecting structure can be composed of several connecting columns or several arc-shaped connecting walls. Since the walking mechanism 3 fixes the encircling body 1 to the post insulator by clamping and has the climbing function of driving the encircling body 1 to move on the post insulator, it can be realized by the cooperation of a drive component and a transmission component. The key technical point of this application is that the walking mechanism 3 can adaptively clamp and compensate for the diameter of each skirt of the post insulator through properties such as elasticity or gas expansion characteristics, so as to ensure that it can adapt to the size of the skirts on the entire post insulator during the climbing process.

[0047] In one embodiment, a compressed elastic component can be provided between the enclosing body 1 and the walking mechanism 3. Through its rebound action, it can effectively clamp insulator skirts of different sizes, enabling the walking mechanism 3 to climb effectively. This avoids climbing failure due to changes in skirt size, specifically, as the skirt diameter continuously shrinks, resulting in insufficient clamping force from the walking mechanism 3 and subsequent climbing failure. Furthermore, the elastic component can adapt to various insulator skirt diameters through its rebound action, ensuring the walking mechanism 3 maintains effective climbing capabilities even with skirts of different diameters.

[0048] Furthermore, refer to Figure 1 and Figure 6 As shown, in some embodiments, the walking mechanism 3 includes a first driving component 31 and a first transmission assembly; the first driving component 31 is disposed on the first transmission assembly; the first transmission assembly includes a driving wheel 32 and a driven wheel 33 arranged at intervals, the driving wheel 32 is synchronously rotatably connected to the first driving component 31, the driven wheel 33 meshes with the driving wheel 32 through a transmission component 34, and a plurality of support rollers 35 are also arranged between the driving wheel 32 and the driven wheel 33 for pressing part of the transmission component 34 onto the post insulator;

[0049] The transmission component 34 has elastic properties to adapt to several different diameter sizes on the post insulator.

[0050] Specifically, in the technical solution adopted in this application, the climbing function is achieved through the cooperation of the first driving component 31 and the first transmission component. The first transmission component includes a driving wheel 32 connected to the first driving component 31 and a driven wheel 33 meshing with the driving wheel 32 through a transmission component 34. This enables the first driving component 31 to drive the driving wheel 32, the driven wheel 33, and the transmission component 34 to rotate synchronously. The transmission component 34, which is sleeved on the driving wheel 32 and the driven wheel 33, enables the climbing function of the body 1. Preferably, the transmission component 34 can be equipped with elasticity to adaptively compensate for changes in the diameter of the umbrella skirt of the post insulator. It should be noted that the walking mechanism 3 has a transmission component 34 with elasticity or is an elastic component disclosed above. Satisfying one of the two structural features can realize the compensation function during the climbing process. It can also have both of the above structural combinations to make the cleaning device more versatile.

[0051] To prevent the traveling mechanism 3 from hitting the insulator during the compensation process, this application preferably provides a spring force characteristic on the transmission component 34.

[0052] Furthermore, refer to Figure 6 As shown, in some embodiments, the transmission component 34 is a ring-shaped track, which is fitted onto the drive wheel 32, the driven wheel 33 and the support wheel 35.

[0053] The track has a sealed filling cavity inside, and air can be injected into the track to form an airbag. When the track is compressed, it can undergo elastic deformation through the airbag.

[0054] Specifically, to achieve this, the technical solution adopted in this application provides a first embodiment of the transmission component 34, which is to set the transmission component 34 as a walking track, and the walking track has a sealed filling space inside. The walking track is made of elastic material. When air is injected into the filling space, the walking track has a certain expansion coefficient to form an airbag elastic layer inside. When the walking track is squeezed by the insulator, it can undergo elastic deformation. Thus, when the walking track faces a relatively large diameter skirt, it can be adapted by squeezing the walking track. When switching to a relatively small diameter skirt, the walking track rebounds due to the gas pressure, thereby automatically adapting to the size difference.

[0055] When in use, a certain amount of air can be injected into the air bladder of the walking track in advance. Through the expansion and rebound characteristics of the gas, the walking track can be adapted to several insulator skirts of different sizes at the same time, so that the walking mechanism 3 can perform stable and effective climbing work on the support insulator.

[0056] Furthermore, refer to Figure 6 As shown, in some embodiments, the transmission component 34 is a ring-shaped track, which is fitted onto the drive wheel 32, the driven wheel 33 and the support wheel 35.

[0057] The track has an internal mounting chamber containing a spring array. When the track is compressed, it can undergo elastic deformation through the spring array.

[0058] Specifically, to achieve this, the technical solution adopted in this application provides a second embodiment of the transmission component 34, which has the same structural part as the first embodiment of the transmission component 34, and therefore will not be described in detail. Specifically, the internal part of the track has a mounting chamber, and a compression spring array is arranged in the mounting chamber. When the track is compressed by an external force, pressure can be applied to the compression spring array inside the mounting chamber to give the track elasticity. In some embodiments, the compression spring array can be a pressure spring to form an elastic layer inside the transmission component 34 that functions similarly to an airbag. Due to the spring pressure, the track rebounds, thereby automatically and adaptively compensating for dimensional discrepancies.

[0059] Furthermore, refer to Figure 3 and Figure 4As shown, in some embodiments, the cleaning mechanism 2 includes a base 21 and a plurality of brushes 22; the base 21 is arranged circumferentially along the outer edge of the body 1, and each brush is rotatably mounted on the corresponding base 21; each base 21 is also provided with a drive mechanism connected to the brush 22 for driving the brush 22 to rotate.

[0060] Specifically, in the technical solution adopted in this application, several bases 21 are installed on the outer edges of both ends of the main body 1. In a preferred embodiment, two bases 21 can be configured on the outer edge of one end of the main body 1. Each base 21 is equipped with two brushes 22. The brushes 22 can be ring-shaped cleaning brushes and are rotatably mounted on the base 21. Each base 21 is also provided with a drive mechanism to drive the brushes 22 to rotate and complete the cleaning work.

[0061] In one embodiment, each brush member 22 has a protruding nozzle 28 at its center. Each nozzle 28 is connected to a water source and its spray direction is set towards the insulator, thereby spraying water onto the insulator to complete a spray-type cleaning operation in conjunction with the brush member 22. It should be noted that the nozzle 28 can be configured not to rotate with the brush member 22 and can be a non-rotatable fixed component, thus ensuring that the spray direction of each nozzle 28 is fixed.

[0062] Further, see attached document. Figure 1 In some embodiments, the drive mechanism includes a second drive component 23 and a second transmission assembly; the second drive component 23 is fixedly installed on the side of the base 21 away from the brush component 22; the second transmission assembly is connected between the second drive component 23 and the corresponding brush component 22, so that the second drive component 23 can drive the corresponding brush component 22 to rotate through the second transmission assembly.

[0063] Furthermore, refer to Figure 4 As shown, in some embodiments, the second transmission assembly includes synchronous pulleys 24 that are synchronously rotatable on the shafts of each brush member 22, and a transmission belt 25 sleeved on each synchronous pulley 24; the transmission belt 25 engages on the output shaft of the second drive member 23.

[0064] Specifically, in order to achieve this, the technical solution adopted in this application allows the rotating shafts of each brush component 22 to pass through the base 21 and be connected to the drive mechanism. The drive mechanism mainly includes a second drive component 23 and a second transmission assembly. The second drive component 23 can be a drive motor mounted on the base 21 via a motor mount. The second transmission assembly consists of a synchronous pulley 24 and a transmission belt 25. The synchronous pulleys 24 are respectively and synchronously rotated on the rotating shafts of the corresponding brush components 22 and are located on the side of the base 21 away from the brush components 22. Both synchronous pulleys 24 are connected to the output shaft of the first drive component 31 via the transmission belt 25, so as to realize that the second drive component 23, in cooperation with the second transmission assembly, drives each brush component 22 to rotate on the base 21.

[0065] In one embodiment, each brush component 22 may be equipped with a drive mechanism, which connects each brush component 22 to a second drive component 23. That is, each brush component 22 is connected to a drive motor, so that the second drive component 23 directly drives the brush component 22 to rotate on the base 21.

[0066] Furthermore, refer to Figure 4 As shown, in some embodiments, the base 21 is also provided with an arc-shaped rack structure 26 and an arc-shaped guide groove (not shown in the figure) that can cooperate with the rack structure 26; the base 21 is slidably mounted on the circumferential body 1 through the cooperation of the limiting post and the arc-shaped guide groove; the rack structure 26 is connected to the motor component 27 and fixes the motor component 27 on the circumferential body 1, for driving the base 21 to slide along the extension direction of the arc-shaped guide groove through the motor component 27.

[0067] Specifically, in the technical solution adopted in this application, an arc-shaped rack structure 26 is provided on the outer side of the bottom of the base 21, and an arc-shaped guide groove adapted to the rack structure 26 is provided on the body of the base 21. The base 21 can be installed on the outer edge of the encircling body 1 by means of a limiting post and the arc-shaped guide groove, so that the base 21 can slide on the encircling body 1 through the cooperation of the limiting post and the arc-shaped guide groove. The rack structure 26 meshes with the gear on the output shaft of the motor component 27, and the forward and reverse rotation of the output shaft of the motor component 27 drives the base 21 to slide back and forth along the extension direction of the arc-shaped guide groove.

[0068] In use, when the post insulator is brushed and cleaned by the cleaning mechanism 2, the base 21 can be driven by the motor 27 to slide back and forth on the outer edge of the body 1, so that each brush 22 can rotate around itself and revolve around the body 1. It should be noted that the revolve performance around the body 1 does not need to go around the body 1 completely, but only needs to fill the gap between adjacent brushes 22, thereby improving the cleaning quality and avoiding omissions during the cleaning process.

[0069] Furthermore, refer to Figure 6 As shown, in some embodiments, the walking mechanism 3 is connected to the surrounding body 1 via an adjustment mechanism 4; the adjustment mechanism 4 includes a linkage assembly 41 and a third drive component 42; the linkage assembly 41 is adjustablely connected between the surrounding body 1 and the walking mechanism 3; the third drive component 42 is fixedly mounted on the surrounding body 1, and the drive part of the third drive component 42 is connected to the adjustment rod in the middle of the linkage assembly 41, so that the third drive component 42 can adjust the position of the walking mechanism 3 via the linkage assembly 41.

[0070] Specifically, in the technical solution adopted in this application, the adjustment mechanism 4 is used to adjust the position of the walking mechanism 3, and specifically includes a linkage assembly 41 and a third drive component 42. The walking mechanism 3 is adjustablely mounted on the encircling body 1 through the linkage assembly 41, while the third drive component 42 is connected between the linkage assembly 41 and the encircling body 1, and is used to drive the walking mechanism 3 to adjust its position inside the encircling body 1 through the linkage assembly 41.

[0071] In one embodiment, the linkage assembly 41 includes two mounting rods and a connecting rod that adjustably connects the two mounting rods. The two ends of the mounting rods are hinged to the housings of the enclosing body 1 and the traveling mechanism 3, respectively. The two ends of the connecting rod are connected to the middle positions of the two mounting rods, and the connecting rod is connected to a third drive component 42. The third drive component 42 consists of a telescopic cylinder and a shock-absorbing spring. The telescopic cylinder is fixedly mounted on the enclosing body 1, and the shock-absorbing spring is sleeved on the outer end of the telescopic cylinder. The outer end of the telescopic cylinder, after cooperating with the shock-absorbing spring, is connected to the connecting rod, allowing the position of the traveling mechanism 3 to be adjusted via the telescopic cylinder, and providing a flexible clamping effect via the shock-absorbing spring. This enables the adjustment function to accommodate insulator skirts of more diameters.

[0072] Furthermore, refer to Figure 7 and Figure 8 As shown, in some embodiments, it further includes: a locking mechanism 5, which is disposed in the encircling body 1;

[0073] The locking mechanism 5 includes a limiting member 51 and a locking member 52 disposed on the limiting member 51 by means of an elastic element; the limiting member 51 is used to limit the position of the locking member 52, and the locking member 52 can be ejected away from the limiting member 51 by means of the elastic element to engage in the gap of the outer layer of the post insulator.

[0074] Specifically, in the technical solution adopted in this application, the locking mechanism 5 is designed to prevent the cleaning device from falling due to a sudden power outage. Specifically, a limiting component 51 and a locking component 52, which is mounted on the limiting component 51 via an elastic element, are configured on the inner side of the enclosing body 1. The limiting component 51 can be an electromagnet, and the locking component 52 can be a rod-shaped component. The rod-shaped component is made of a material that can be attracted to the electromagnet. When the cleaning device is normally powered on, the electromagnet has a strong magnetic attraction force, which compresses the second elastic element 53, causing the rod-shaped component to adhere to the electromagnet. When the cleaning device is powered off, the electromagnet loses its magnetic attraction force, and the rod-shaped component can be ejected outward by the rebound force of the second elastic element 53, ultimately acting in the gap between the insulator skirts to secure the cleaning device to the post insulator after the power outage, thus preventing the cleaning device from falling directly and causing danger. In one embodiment, a flexible protective layer is fitted on the outer layer of the locking component 52 to prevent the locking component 52 from damaging the external structure of the insulator in an emergency due to the rebound of the elastic element.

[0075] The cleaning device for post insulators provided in this application embodiment, as a preferred embodiment, mainly consists of a ring-shaped body 1, whose core structure is a ring-shaped frame, serving as the base for supporting the walking mechanism 3 and the cleaning structure. The cleaning mechanism 2 comprises a base 21, a brush 22 mounted on the outer edge of the ring-shaped body 1 via the base 21, and a nozzle. The nozzle sprays cleaning fluid onto the insulator, and the brush 22 rotates to clean the insulator. The nozzles near the upper edge of the ring-shaped body 1 can be configured to spray cleaning fluid, while the nozzles near the lower edge can be configured to spray pure water, thus achieving both brushing and rinsing cleaning steps. The walking mechanism 3 is mainly installed inside the ring-shaped body 1 via an adjusting mechanism 4. Preferably, at least three walking mechanisms 3 are provided inside the ring-shaped body 1, so that the walking mechanisms 3 press against each other to form a clamping force, allowing the ring-shaped body 1 to be stably fastened to the outer surface of the insulator through the various walking mechanisms 3.
