Description

Technical Field

[0001] This application relates to the field of GIS combined electrical appliance pipe cleaning technology, and in particular to an adhesive roller device and cleaning device for cleaning GIS pipes. Background Technology

[0002] During the production, assembly, transportation, installation, and subsequent maintenance of GIS (Gas Insulated Switchgear) combined electrical contaminants, metal particles, metal debris, and other particulate contaminants are easily left inside the piping. Once these particles adhere to or remain inside the GIS piping, they may adversely affect the insulation performance and operational reliability of the equipment. Therefore, it is necessary to effectively clean the inside of the GIS piping. Currently, common cleaning methods mainly include brush roller cleaning and roller adhesion cleaning. When the above solutions are applied to the inside of GIS piping, the following limitations still exist: (1) The internal space of GIS piping is relatively closed and the working area is long and narrow, making it difficult for cleaning devices to enter and operate, resulting in many cleaning dead corners and affecting the overall cleaning effect; (2) The contact pressure of the cleaning components is difficult to adjust. On the one hand, the contact pressure is usually achieved by manual experience or mechanical pre-tightening, which makes it difficult to dynamically adjust according to different working conditions; on the other hand, there is a lack of effective pressure feedback means, and the pressure can only be estimated by adjusting the position of the component, the motor rotation angle, the mechanical pre-tightening amount, or experience, which makes it impossible to know the pressure in real time, resulting in large pressure adjustment errors, poor repeatability, and insufficient stability. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. Therefore, the purpose of this application is to provide a viscous roller device and a cleaning device for cleaning GIS pipelines, aiming to solve the problems of difficulty in operation of the cleaning device within the pipeline space and difficulty in adjusting the contact pressure.

[0004] In a first aspect, this application proposes an adhesive roller device for cleaning GIS pipelines. The adhesive roller device includes a mounting frame, an adhesive roller, a telescopic rod, an adjusting assembly, and a pressure rod assembly. Torsion springs are respectively provided on both sides of the mounting frame. The axial ends of the adhesive roller are respectively connected to both sides of the mounting frame via the telescopic rod. The telescopic rod is used to extend and retract to move the adhesive roller relative to the mounting frame. One end of the torsion spring is connected to the telescopic rod. The adjusting assembly is mounted on the mounting frame. The pressure rod assembly includes a first pressure rod and a second pressure rod, with a pressure sensor provided between the first and second pressure rods. The first pressure rod is connected to the adjusting assembly, and the second pressure rod is connected to the other end of the torsion spring, for clamping the pressure sensor between the first and second pressure rods. The adjusting assembly is used to drive the first pressure rod to move relative to the mounting frame.

[0005] According to this application, the adhesive roller device for cleaning GIS pipelines improves the mobility of the adhesive roller and expands its working range by incorporating a telescopic rod, solving the problem of limited movement and difficult operation of the adhesive roller in narrow, enclosed spaces within pipelines. By setting up an adjustment component, a pressure rod component, and a torsion spring that cooperate with the telescopic rod, a stable and reliable force transmission path is established, allowing for flexible adjustment of the contact pressure of the adhesive roller against the pipeline inner wall, thus improving the cleaning effect and solving the problem of fixed contact pressure that makes it difficult to adapt to different cleaning conditions. Simultaneously, a pressure sensor can monitor the contact pressure of the adhesive roller in real time during cleaning and pressure adjustment, providing real-time feedback on the pressure adjustment process, thereby improving the accuracy, stability, and repeatability of pressure regulation. The adhesive roller device of this application simultaneously possesses pressure adjustment, feedback, buffering, and cleaning functions, which is beneficial for stable application in environments with limited space and high cleaning requirements in GIS pipelines.

[0006] According to some embodiments of this application, the two side walls of the mounting bracket are respectively provided with sliding grooves, and the two ends of the second pressure rod are respectively connected to the corresponding sliding grooves; wherein, the two ends of the second pressure rod extend to the outside of the mounting bracket to connect with the corresponding torsion spring.

[0009] According to some embodiments of this application, the adjustment assembly includes at least two cams, wherein the two cams are respectively disposed near the two ends of the first pressure rod, and the cams are connected to each other by a linkage.

[0010] According to some embodiments of this application, the telescopic rod is rotatably connected to the mounting bracket.

[0011] According to some embodiments of this application, the mounting bracket is provided with a limiting part, which is used to limit the rotation angle of the telescopic rod.

[0012] According to some embodiments of this application, the adhesive roller device further includes an image acquisition component, which is disposed on a mounting frame or telescopic rod, and is used to monitor the cleanliness of the inner wall of the pipe.

[0013] According to some embodiments of this application, the outer diameter of the adhesive roller gradually decreases from the middle to both ends.

[0014] Secondly, this application also proposes a cleaning device, including the aforementioned adhesive roller device and a moving trolley, wherein the mounting frame is connected to the moving trolley, and the moving trolley is used to drive the adhesive roller device to move within the pipeline.

[0015] According to the cleaning device of this application, the viscous roller device is moved inside the pipe by a moving trolley, which can further penetrate the pipe and expand the cleaning range, reduce cleaning dead corners, improve cleaning quality, and simplify cleaning operation and improve cleaning efficiency.

[0016] The adhesive roller device and cleaning device according to this application have the following technical advantages compared with the prior art: (1) The structure is compact and the movement is flexible, which can adapt to the narrow working space inside the GIS pipeline, expand the cleaning range and reduce cleaning dead corners; (2) A clear, stable and reliable force transmission path has been established, which can make the sticky roller and the inner wall of the pipe in stable contact during the cleaning operation; moreover, the contact pressure of the sticky roller can be flexibly adjusted according to the pipe working conditions and cleaning needs, thereby improving the cleaning effect; in addition, it has a real-time pressure feedback function, which can improve the accuracy of pressure regulation and avoid open-loop regulation error.

Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] The following is for reference. Figures 1-5 This application describes an adhesive roller device for cleaning GIS pipelines according to embodiments of the present application.

[0022] In a first aspect, this application proposes an adhesive roller device for cleaning GIS pipelines. The adhesive roller device includes a mounting frame 10, an adhesive roller 20, a telescopic rod 30, an adjusting assembly, and a pressure rod assembly. Torsion springs 50 are respectively provided on both sides of the mounting frame 10. The axial ends of the adhesive roller 20 are respectively connected to both sides of the mounting frame 10 via the telescopic rod 30. The telescopic rod 30 is used to extend and retract to drive the adhesive roller 20 to move relative to the mounting frame 10. One end of the torsion spring 50 is connected to the telescopic rod 30. The adjusting assembly is disposed on the mounting frame 10. The pressure rod assembly includes a first pressure rod 41 and a second pressure rod 42, with a pressure sensor 43 disposed between the first pressure rod 41 and the second pressure rod 42. The first pressure rod 41 is connected to the adjusting assembly, and the second pressure rod 42 is connected to the other end of the torsion spring 50, for clamping the pressure sensor 43 between the first pressure rod 41 and the second pressure rod 42. The adjusting assembly is used to drive the first pressure rod 41 to move relative to the mounting frame 10.

[0023] Among them, such as Figure 1As shown, mounting bracket 10 provides a mounting base for the adhesive roller 20, telescopic rod 30, pressure rod assembly, torsion spring 50, and adjustment assembly. In application, the adhesive roller 20 can be rolled against the inner wall of the GIS pipe by moving mounting bracket 10. The adhesive roller 20 is the primary cleaning component, such as... Figure 2 As shown, when its outer surface comes into contact with the inner wall of the GIS pipe 200, it can adhere to the metal particles 300 inside the GIS pipe, thereby achieving GIS pipe cleaning.

[0024] The adhesive roller 20 has its axial ends connected to both sides of the mounting frame 10 via telescopic rods 30. The telescopic rods 30 are used to install and support the adhesive roller 20, and to bear and transmit the forces applied by the adjustment assembly, the pressure rod assembly, and the torsion spring. The telescopic rods 30 can extend and retract to move the adhesive roller 20 relative to the mounting frame 10, thereby changing the position of the adhesive roller 20 and enabling it to move axially along the pipeline, thus adjusting and expanding the cleaning range and reducing cleaning dead zones.

[0025] Furthermore, the adjusting assembly, the first pressure rod 41, the pressure sensor 43, the second pressure rod 42, the torsion spring 50, the telescopic rod 30, and the viscous roller 20 are connected in sequence to establish a complete force transmission system. The viscous roller 20 contacts the inner wall of the GIS pipe with a certain contact pressure, which is applied to the torsion spring 50 through the telescopic rod 30. The pressure rod assembly is located between the adjusting assembly and the torsion spring 50, maintaining force balance so that the first pressure rod 41 and the second pressure rod 42 clamp the pressure sensor 43. The adjusting assembly can apply a force to the first pressure rod 41 and adjust the magnitude of the force, driving the first pressure rod 41 to move relative to the mounting bracket 10, adjusting the position of the first pressure rod 41, and thus driving the pressure sensor 43 and the second pressure rod 42 to move, thereby changing the deformation and elastic restoring force of the torsion spring 50. The elastic restoring force of the torsion spring 50 reacts to the second pressure rod 42 and the telescopic rod 30, causing pressure changes between the first pressure rod 41 and the second pressure rod 42, and pressure changes on the telescopic rod 30 caused by the torsion spring 50. These pressure changes are transmitted to the adhesive roller 20, thus regulating the contact pressure between the adhesive roller 20 and the inner wall of the GIS pipe. By changing the contact pressure of the adhesive roller 20, it can adapt to different GIS pipe wall conditions (such as different cleaning areas and different particle adhesion conditions), improving the cleaning effect and avoiding problems such as insufficient adhesion and incomplete cleaning due to insufficient pressure, as well as problems such as increased wear and increased movement resistance caused by excessive pressure on the adhesive roller 20 and the inner wall of the GIS pipe.

[0026] The pressure sensor 43, located between the first pressure rod 41 and the second pressure rod 42, serves to transmit and detect pressure. It monitors the pressure signal along the force transmission path in real time and provides feedback, laying the structural foundation for subsequent semi-closed-loop or closed-loop control. The placement of the pressure sensor 43 makes signal detection more direct and calibration easier. Based on the correspondence between the pressure signal and the contact pressure, the actual contact pressure change of the adhesive roller 20 can be accurately obtained, facilitating target pressure setting, pressure range control, or overpressure protection. This allows for timely adjustment of the contact pressure of the adhesive roller 20 via the adjustment components. The correspondence between the pressure signal and the contact pressure can be pre-established through testing. The torsion spring 50 connects the second pressure rod 42 and the telescopic rod 30. Through elastic loading, it makes the pressing process of the adhesive roller 20 smoother, acting as a buffer against localized impacts, instantaneous fluctuations, or uneven force during the cleaning process, thus improving the stability of pressure transmission, pressure regulation, and pressure monitoring.

[0027] According to the adhesive roller device for cleaning GIS pipelines disclosed in this application, the telescopic rod 30 improves the mobility of the adhesive roller 20, expands its working range, and solves the problem of the adhesive roller 20 being unable to move properly and causing operational difficulties in narrow, enclosed spaces within pipelines. By incorporating an adjustment assembly, a pressure rod assembly, and a torsion spring 50 that cooperate with the telescopic rod 30, a stable and reliable force transmission path is established, allowing for flexible adjustment of the contact pressure of the adhesive roller 20 against the pipeline inner wall, thus improving the cleaning effect and solving the problem of the adhesive roller 20 having fixed contact pressure and being difficult to adapt to different cleaning conditions. Simultaneously, the pressure sensor 43 can monitor the contact pressure of the adhesive roller 20 in real time during the cleaning and pressure adjustment processes, enabling real-time feedback on the pressure adjustment process and improving the accuracy, stability, and repeatability of pressure regulation. The adhesive roller device of this application simultaneously possesses pressure adjustment, feedback, buffering, and cleaning functions, which is beneficial for stable application in environments with limited space and high cleaning requirements in GIS pipelines.

[0028] The adhesive roller device of this application is mainly used for cleaning metal particles inside GIS pipelines, but it is not limited to this and can also be used for cleaning other materials inside other pipelines.

[0029] In some embodiments, such as Figure 2As shown, the adhesive roller 20 includes a roller body 21 and an adhesive layer 22 disposed on the outer periphery of the roller body 21. The roller body 21 is connected to the telescopic rod 30 via a rotating shaft. The adhesive layer 22 has an adhesive function and can adhere to metal particles 300. To enhance the connection between the roller body 21 and the adhesive layer 22, a groove is provided on the outer periphery of the roller body 21, and a portion of the adhesive layer 22 engages with this groove. The material of the adhesive layer 22 can be determined according to the type of metal particles, environmental requirements, and wear resistance needs. Furthermore, the roller body 21 has multiple weight-reducing holes to reduce weight and improve mobility.

[0030] In some embodiments, such as Figure 1 , Figure 3 As shown, the mounting frame 10 includes two side walls 11, two telescopic rods 30 and corresponding torsion springs 50 are respectively disposed on the outer side of the side walls 11, and the adjusting assembly and the pressure rod assembly are disposed between the two side walls 11. This embodiment allows for a compact structure of the adhesive roller device, thus adapting to the confined space within GIS pipelines.

[0031] According to some embodiments of this application, the two side walls 11 of the mounting bracket 10 are respectively provided with sliding grooves 12, and the two ends of the second pressure rod 42 are respectively connected to the corresponding sliding grooves 12; wherein, the two ends of the second pressure rod 42 extend to the outside of the mounting bracket 10 to connect with the corresponding torsion springs 50. When the adjusting component drives the first pressure rod 41 to move, the second pressure rod 42 moves synchronously with the first pressure rod 41. Figure 1 , Figure 3 As shown, the second pressure rod 42 is connected to the slide groove 12. The slide groove 12 can constrain the movement path of the second pressure rod 42, thereby improving the stability of pressure transmission.

[0032] In some embodiments, the direction of the force exerted by the adjusting component on the first pressure rod 41 is the same as the extension direction of the slide groove 12, which simplifies the direction of force transmission and improves the accuracy of pressure adjustment. Specifically, in some embodiments, the slide groove 12 extends in a vertical direction.

[0033] According to some embodiments of this application, the first pressure rod 41 has bent portions 411 at both ends, and the bent portions 411 have connecting holes 412; wherein, the second pressure rod 42 passes through the connecting holes 412 to restrict the relative movement between the first pressure rod 41 and the second pressure rod 42. Figure 3 , Figure 4 As shown, by setting the bending part 411 and the connecting hole 412, the second pressure rod 42 can be connected to the first pressure rod 41, thereby improving the stability of pressure transmission; moreover, the main body parts of the first pressure rod 41 and the second pressure rod 42 can be kept parallel, thereby facilitating the setting of the pressure sensor 43 between the first pressure rod 41 and the second pressure rod 42.

[0034] In some embodiments, the extending directions of the first pressure rod 41 and the second pressure rod 42 are perpendicular to their force direction. For example... Figure 3 As shown, the first pressure rod 41 and the second pressure rod 42 extend horizontally, and the slide groove 12 extends vertically. The force exerted by the adjusting assembly on the first pressure rod 41 is vertical. Furthermore, the second pressure rod 42 is in contact with the side wall of the connecting hole 412 to limit the lateral movement of the first pressure rod 41. There is a gap between the second pressure rod 42 and the top and bottom walls of the connecting hole 412, ensuring that pressure can only be transmitted between the first pressure rod 41 and the second pressure rod 42 through the intermediate pressure sensor 43, thus guaranteeing the accuracy of pressure detection.

[0035] like Figure 3 , 4 As shown, the first pressure rod 41 is disposed between the two side walls 11 of the mounting bracket 10, and the end of the second pressure rod 42 passes through the corresponding connecting hole 412 and the slide groove 12, extending to the outside of the side wall 11 to connect with the corresponding torsion spring 50.

[0036] In some embodiments, the two ends of the first pressure rod 41 are respectively connected to the slide groove 12, and the two ends of the first pressure rod 41 respectively penetrate the slide groove 12 and extend to the outside of the side wall 11; further, the two ends of the first pressure rod 41 are provided with stop portions, which partially cooperate with the side wall 11 on the outer periphery of the slide groove 12 to restrict the axial movement of the first pressure rod 41. In this embodiment, through the constraint of the slide groove 12, the first pressure rod 41 and the second pressure rod 42 can only move relative to each other along the extension direction of the slide groove 12, but under the constraint of the adjusting component and the torsion spring 50, the first pressure rod 41 and the second pressure rod 42 press against the pressure sensor 43 and maintain synchronous movement.

[0037] According to some embodiments of this application, the telescopic rod 30 is provided with a first slot 31, the end of the second pressure rod 42 is provided with a second slot 42, and the two ends of the torsion spring 50 are respectively connected to the first slot 31 and the second slot 42. The assembly of the torsion spring 50 can be simplified by providing the first slot 31 and the second slot 42.

[0038] According to some embodiments of this application, the adjustment assembly includes a drive motor 61 and a cam 62, which are respectively mounted on the mounting bracket 10. The outer peripheral surface of the cam 62 abuts against the first pressure rod 41. The drive motor 61 is connected to the cam 62 to drive the cam 62 to rotate, thereby moving the first pressure rod 41. Figure 1As shown, when the drive motor 61 drives the cam 62 to rotate, the distance between the contact point between the outer circumferential surface of the cam 62 and the first pressure rod 41 and the rotation center of the cam 62 changes, thereby driving the first pressure rod 41 to move. The adjustment assembly in this embodiment adjusts the contact pressure between the viscous roller 20 and the inner wall of the pipe by indirectly loading the viscous roller 20. It has a simple structure, high efficiency, and high control precision. Specifically, when it is necessary to increase the contact pressure between the viscous roller 20 and the inner wall of the pipe, the drive motor 61 drives the cam 62 to rotate in the direction of increasing the deformation of the torsion spring 50, increasing the downward pressure of the pressure rod assembly and increasing the elastic force of the torsion spring 50; when it is necessary to decrease the contact pressure, the drive motor 61 drives the cam 62 in the opposite direction, decreasing the downward pressure of the pressure rod assembly and reducing the elastic force of the torsion spring 50, thereby reducing the loading force on the viscous roller 20.

[0039] In some embodiments, the cam 62 is constructed as an Archimedean spiral cam 62, which can convert the uniform rotation output by the drive motor 61 into uniform linear motion of the first pressure rod 41, thereby making the pressure regulation control more precise and controllable. The drive motor 61 can be a stepper motor, a servo motor, or other controllable drive components, and its function is to provide active driving force for contact pressure regulation.

[0040] In the above embodiment, the force and motion transmission relationship of the viscous roller device is as follows: the drive motor 61 drives the Archimedes spiral cam 62 to rotate → the force exerted by the Archimedes spiral cam 62 on the first pressure rod 41 changes → the first pressure rod 41 drives the pressure sensor 43 and the second pressure rod 42 to move → the torsion spring 50 deforms and its elastic restoring force changes → the force exerted by the torsion spring 50 on the pressure rod assembly and the telescopic rod 30 changes → the force exerted by the telescopic rod 30 on the viscous roller 20 changes → the contact pressure of the viscous roller 20 on the GIS pipeline changes. Specifically, the second pressure rod 42 presses the pressure sensor 43 based on the reverse force of the torsion spring 50 → the pressure sensor 43 detects the pressure in the transmission path.

[0041] In some embodiments, such as Figure 1 , 3 As shown, the mounting bracket 10 is provided with a motor bracket 64, which connects two side walls 11; wherein, the drive motor 61 and the cam 62 are provided on the motor bracket 64, and the outer peripheral surface of the cam 62 is directly opposite to the first pressure rod 41 in the vertical direction.

[0042] In some embodiments, the pressure sensor 43 is connected to the controller via a signal line, and the controller is connected to the drive motor 61. The pressure signal output by the pressure sensor 43 serves as the basis for the operation of the drive motor 61. The controller presets a target pressure value or a target pressure range: when the pressure sensor 43 detects a value below the target lower limit, the controller controls the drive motor 61 to rotate in the pressure-increasing direction; when the pressure sensor 43 detects a value above the target upper limit, the controller controls the drive motor 61 to rotate in the pressure-reducing direction; when the pressure sensor 43 detects a value within the target range, the controller controls the drive motor 61 to stop or maintain its current position. This embodiment can improve the accuracy of pressure setting, enhance the consistency of repeated adjustments, and avoid pressure deviations caused by mechanical wear, assembly errors, etc., providing a foundation for automatic pressure regulation and intelligent control.

[0043] In some embodiments, the pressure sensor 43 may be in different forms such as piezoresistive, strain gauge, or thin film.

[0044] According to some embodiments of this application, the adjusting assembly includes at least two cams 62, wherein the two cams 62 are respectively disposed near the two ends of the first pressure rod 41, and the cams 62 are connected by a linkage 63. For example... Figure 1 As shown, by setting two or more cams 62 to synchronously control the movement of the first pressure rod 41, the uniformity of force distribution within the length of the first pressure rod 41 can be improved. The multiple cams 62 are connected by a linkage 63, allowing the drive motor 61 to drive one cam 62, thereby causing the other cams 62 to rotate synchronously. This reduces control complexity and simplifies the structure.

[0045] According to some embodiments of this application, the telescopic rod 30 is rotatably connected to the mounting bracket 10. For example, Figure 1 , Figure 3 As shown, the telescopic rod 30 is installed using a swing-arm type. One end is rotatably connected to the adhesive roller 20, allowing it to rotate relative to the adhesive roller 20; the other end is rotatably connected to the mounting frame 10, allowing it to rotate relative to the mounting frame 10. Under the elastic force of the torsion spring 50, the telescopic rod 30 swings around the connection point with the mounting frame 10, causing the adhesive roller 20 to move towards and press against the inner wall of the pipe. This embodiment is suitable for scenarios where the internal space of a GIS pipeline is limited and the adhesive roller 20 needs to have a certain margin for attitude adjustment. Due to the flexibility of the swing-arm structure, the adhesive roller 20 is more likely to maintain a stable fit with the pipe wall when encountering changes in local contact conditions. Combined with the adjustment function of the telescopic rod 30, this embodiment can further improve the flexibility and adaptability of the adhesive roller 20, enabling it to adapt to abnormal working conditions such as undulations or protrusions in the inner wall of the pipe, alleviating the contact instability problem caused by local attitude changes, and improving the adhesion ability of the adhesive roller 20 to the pipe wall.

[0046] According to some embodiments of this application, the mounting bracket 10 is provided with a limiting part 13, which is used to limit the rotation angle of the telescopic rod 30. The telescopic rod 30 is adapted to abut against the limiting part 13 when rotating relative to the mounting bracket 10, and the limiting part 13 is used to limit the rotation angle of the telescopic rod 30.

[0047] In some embodiments, the telescopic rod 30 includes a telescopic drive assembly, a first connecting rod, and a second connecting rod, with the first connecting rod and the second connecting rod slidably connected. The telescopic drive assembly drives the first connecting rod to move relative to the second connecting rod. The telescopic drive assembly provides a driving force to push the first connecting rod to slide relative to the second connecting rod, thereby changing the extension length of the telescopic rod 30 and adjusting the position of the adhesive roller 20. The telescopic drive assembly can be configured as an electric push rod, a rack and pinion drive assembly, a hydraulic drive assembly, etc.

[0048] According to some embodiments of this application, the adhesive roller device further includes an image acquisition component, which is disposed on the mounting frame 10 or the telescopic rod 30, and is used to monitor the cleanliness of the inner wall of the pipe. For example... Figure 1 , Figure 5 As shown, by setting up an image acquisition component, images of the inner wall of the pipe can be acquired in real time. This allows for the identification of the cleaning area and observation of any remaining metal particles within that area, thus determining whether further cleaning is necessary and whether the position or contact pressure of the adhesive roller 20 needs adjustment. The image acquisition component provides feedback on the cleaning effect, solving the problem of difficulty in real-time confirmation of the cleaning effect inside pipes in existing technologies, and helping to improve cleaning efficiency and quality. In some embodiments, the image acquisition component may be a camera 71.

[0049] Furthermore, such as Figure 5 As shown, a camera bracket 72 is provided on the telescopic rod 30, and two telescopic rods 30 are connected to the two sides of the camera bracket 72 respectively. The camera 71 is mounted on the camera bracket 72. Furthermore, the camera 71 is located in the middle of the camera bracket 72, and its acquisition end is set at an angle downward to facilitate the acquisition of images of the inner wall of the pipe near the viscous roller 20.

[0050] According to some embodiments of this application, the outer diameter of the adhesive roller 20 gradually decreases from the middle to both ends. For example, Figure 1-5 As shown, the outer diameter of the adhesive roller 20 gradually decreases from the middle to both ends, which allows the outer circumferential contour of the adhesive roller 20 to better fit the contour of the inner wall of the pipe, thereby achieving a uniform and efficient cleaning effect within the cleaning range.

[0051] Furthermore, the adhesive roller 20 and the telescopic rod 30 are detachably connected, so as to match the appropriate adhesive roller 20 according to the working conditions of the pipe to be cleaned, and to facilitate timely cleaning, maintenance and replacement of the adhesive roller 20, shorten maintenance time, reduce replacement difficulty and improve the overall reuse efficiency of the machine; and enable the adhesive roller 20 to be quickly disassembled and assembled when there are many metal particles adhering to it, the adhesive layer 22 is worn or needs maintenance.

[0052] The adhesive roller device of this application has a compact structure, making it suitable for the confined working space inside GIS pipelines. Furthermore, the adhesive roller device of this application is highly integrated, achieving a unified design for cleaning position adjustment, cleaning pressure regulation, pressure feedback, and cleaning status observation, thus meeting the comprehensive requirements of precision, stability, and visualization for cleaning metal particles inside GIS pipelines. In addition, the adhesive roller device of this application adopts a modular design, facilitating integration and engineering / medical applications.

[0053] The following is for reference. Figure 6 This application describes a cleaning apparatus according to an embodiment of the present application.

[0054] Secondly, this application also proposes a cleaning device, including the aforementioned adhesive roller device 100 and a moving trolley 400, wherein the mounting bracket 10 is connected to the moving trolley 400, and the moving trolley 400 is used to drive the adhesive roller device 100 to move within the pipe.

[0055] Among them, such as Figure 6 As shown, the adhesive roller device 100 of this application is integrated with the mobile trolley 400 as an independent module. The mobile trolley 400 moves the adhesive roller device 100 within the pipe, allowing for deeper cleaning and a wider cleaning range, reducing blind spots, improving cleaning quality, simplifying operations, and increasing efficiency. Furthermore, the adhesive roller device 100 can be installed at the front, bottom, side, or other suitable locations of the mobile trolley 400 to clean areas at different angles along the pipe's perimeter.

[0056] In practical application, the cleaning device of this application operates as follows: A mobile trolley 400 carries the adhesive roller device 100 into the GIS pipeline; upon reaching the target cleaning position, the drive motor 61 starts, causing the Archimedes spiral cam 62 to rotate; the Archimedes spiral cam 62 adjusts the downward pressure of the first pressure rod 41 and the second pressure rod 42 by changing its profile; the torsion spring 50 receives the corresponding force from the pressure rod assembly and transmits this force to the telescopic rod 30, while simultaneously transmitting the force in the opposite direction to the pressure sensor 43; the telescopic rod 30 drives the adhesive roller 20 to press against the inner wall of the GIS pipeline; based on the detection result of the pressure sensor 43, the parameters of the adjusting component are adjusted to adjust the contact pressure of the adhesive roller 20 to the target contact pressure. Under the target contact pressure, the mobile trolley 400 drives the adhesive roller 20 to roll along the pipe wall and adhere to metal particles, thus performing the cleaning operation.

[0057] In some embodiments, the image acquisition component and pressure sensor 43 are both connected to the control system. The detection signals from the image acquisition component and pressure sensor 43 can be transmitted to the control system or display terminal, allowing operators to determine the current pressure loading and cleaning status, or allowing the control system to control the operation of the adjustment component, the movement of the mobile trolley 400, and the deformation of the telescopic rod 30, thereby optimizing the cleaning effect. Furthermore, the detection signals from the image acquisition component and pressure sensor 43 can be fed back to the outside of the pipeline in real time via wired or wireless communication, facilitating monitoring and control by operators outside the pipeline.

[0058] The adhesive roller device and cleaning device according to this application have the following technical advantages compared with the prior art: (1) The structure is compact and the movement is flexible, which can adapt to the narrow working space inside the GIS pipeline, expand the cleaning range and reduce cleaning dead corners; (2) A clear, stable and reliable force transmission path has been established, which can make the sticky roller and the inner wall of the pipe in stable contact during the cleaning operation; moreover, the contact pressure of the sticky roller can be flexibly adjusted according to the pipe working conditions and cleaning needs, thereby improving the cleaning effect; in addition, it has a real-time pressure feedback function, which can improve the accuracy of pressure regulation and avoid open-loop regulation error. (3) It has a high degree of functional integration and has cleaning, pressure regulation, buffering, pressure feedback and cleaning effect feedback functions, which can meet the high cleaning requirements of GIS pipelines. (4) It adopts a modular design, which is highly applicable. The adhesive roller device can be integrated as an independent module into the mobile trolley for microparticle cleaning, further improving the cleaning operation capability and enhancing its applicability.
