[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] At present, the main method for repairing and connecting cracked and leaked municipal pipelines is to stop the flow of energy and then plug it. Stopping the flow of energy and plugging it means that during the pipeline maintenance process, the energy transmission needs to be stopped and then plugged. Although this method can effectively repair the pipeline, it will cause a waste of energy in the pipeline during the stop period, and it will also affect the user's resource usage process.

[0029] Therefore, the methods of stopping transmission and blocking in the related art are complicated to operate and the process is cumbersome, requiring a long maintenance time and having low maintenance efficiency, which not only affects the normal use process of users, but also increases maintenance costs and causes energy waste.

[0030] In order to solve the technical problem, the present invention provides a method and device for plugging a non-stop pipeline.

[0031] See also Figures 1 to 3In one embodiment of the present invention, a leak is formed on the outer wall of the pipeline 10, and the non-stop pipeline 10 plugging device includes a clamping assembly 100 and a plugging mechanism 200, the clamping assembly 100 can be detachably sleeved on the outer circumference of the pipeline 10, the clamping assembly 100 and the outer wall of the pipeline 10 jointly define a guide gap 101 for accommodating the leak, and the guide gap 101 extends along the circumference of the pipeline 10; the plugging mechanism 200 can be detachably arranged in the guide gap 101; the plugging mechanism 200 includes a scraping end and a connecting end, the connecting end can be slidably arranged on the clamping assembly 100 along the guide gap 101, one end of the scraping end is arranged on the side of the connecting end facing the leak, and the other end of the scraping end is arranged against the outer wall of the pipeline 10; wherein the connecting end is connected to an external driving member 300, and is used to rotate around the axis of the pipeline 10 under the drive of the driving member 300, so as to drive the scraping end to slide along the guide gap 101 and scrape the pipeline repair material applied on the leak.

[0032] Specifically, the clamping assembly 100 can be detachably sleeved on the outer circumference of the pipe 10, and together with the outer wall of the pipe 10, defines a guide gap 101 for accommodating the leak. The guide gap 101 extends along the circumference of the pipe 10, effectively ensuring that the plugging device will not deviate during the guiding process, and can accurately control the coating position of the repair material.

[0033] The plugging mechanism 200 can be detachably arranged in the guide gap 101, and its structure includes a scraping end and a connecting end. The connecting end can slide along the guide gap 101 and is connected to the external driving member 300. The driving member 300 enables the connecting end to rotate around the axis of the pipeline 10, thereby driving the scraping end to slide along the guide gap 101. The scraping end is used to scrape the surface of the pipeline 10 to remove pollutants to a certain extent and help apply the repair material. Through the sliding of the scraping end, the repair material can be evenly applied to the leaking place, thereby effectively repairing the leakage problem of the pipeline 10.

[0034] During this process, the scraping end is in close contact with the outer wall of the pipe 10, thereby ensuring the coating accuracy of the repair material and reducing the phenomenon of loose sealing caused by uneven coating of the repair material. The entire process does not require stopping the energy in the pipe 10, and can quickly solve the leakage problem without affecting the energy transmission of the pipe 10.

[0035] More specifically, the clamping assembly 100 can adapt to pipes 10 of different specifications through a detachable connection, and its installation and removal process is simple, saving time and labor costs. The scraping end in the plugging mechanism 200 can evenly apply the repair material, thereby effectively avoiding the problem of poor repair effect or missed repair caused by uneven coating.

[0036] In addition, the device of the present invention can clean the pollutants at the leaking place and apply the repair material more accurately by driving the scraping end to slide under the action of the driving member 300, thereby ensuring the reliability and durability of the plugging effect. This not only reduces the energy waste in the traditional plugging method, but also improves the maintenance efficiency and reduces the maintenance cost. Moreover, it can quickly repair the leakage of the pipeline 10 without interrupting the energy transmission, ensuring the normal operation of the pipeline 10 and reducing the impact on users during the maintenance period.

[0037] It should be understood that the clamping assembly 100 is sleeved on the outer circumference of the pipe 10 and fixed by fasteners to ensure that the clamping assembly 100 is tightly fitted with the outer wall of the pipe 10 to form a guide gap 101 with an opening. The opening of the guide gap 101 is arranged relative to the outer wall of the pipe 10, that is, the outer wall of the pipe 10 is equivalent to the bottom wall of the guide gap 101. The guide gap 101 is used for the plugging mechanism 200 to slide therein, and at the same time ensure that the leak is surrounded by the guide gap 101. When the driving member 300 is started, the plugging mechanism 200 rotates around the axis of the pipe 10, driving the scraping end to slide along the guide gap 101 to scrape the pipe repair material applied to the leak. The scraping end ensures that the repair material at the leak can be evenly applied, thereby effectively plugging the leak.

[0038] Since the plugging mechanism 200 works without stopping the transmission, there is no need to stop the energy transmission in the pipeline 10 during the plugging process, which avoids energy waste and interruption of user resource use, avoids energy waste caused by stopping the transmission and plugging, and reduces maintenance costs. The scraping end can move relative to the leaking part, scrape the plugging material at the leaking part into the leaking part, realize rapid plugging of the leaking part, and improve maintenance efficiency. The guide gap 101 ensures that the scraping end can correspond to the leaking part, improving the accuracy of the plugging. In addition, the detachability of the clamping assembly 100 and the plugging mechanism 200 facilitates rapid disassembly and reuse after maintenance.

[0039] In the technical solution provided by the present invention, through the synergistic effect of the clamping assembly 100 and the sealing mechanism 200, effective sealing of the leaking part of the pipeline 10 is achieved without stopping the flow. The clamping assembly 100 can fit tightly with the outer wall of the pipeline 10 and form a guide gap 101. The gap provides a sliding path for the sealing mechanism 200 and ensures that the leaking part is surrounded, providing a more precise operating space for the construction of the sealing material. The sealing mechanism 200 includes a scraping end and a connecting end, wherein the scraping end is responsible for scraping and coating the repair material on the leaking part, and the connecting end is responsible for driving the scraping end to slide along the guide gap 101 under the action of the driving member 300, thereby avoiding complex mechanical operations and multiple disassembly and assembly of the equipment, thereby reducing the impact on the sealing of the pipeline 10 during the maintenance process, and maintaining the waterproof performance of the pipeline 10 and the reliability of the overall structure. Since the plugging mechanism 200 can work without stopping the flow, it not only simplifies the operation process of the operators and reduces the requirements on the technical level of the operators, but also there is no need to stop the energy delivery in the pipeline 10 during the plugging process, which effectively avoids energy waste and interruption of user resource use, improves plugging efficiency and accuracy, and reduces maintenance costs.

[0040] As an optional embodiment, the clamping assembly 100 includes a plurality of clamping units, each of which includes a clamping arm and a clamping block, one end of the clamping arm is connected to the clamping block, and the other end is connected to the main body of the clamping assembly 100. The clamping block can be in close contact with the outer wall of the pipeline 10, so as to fix the clamping assembly 100 on the pipeline 10. The guide gap 101 defined by the clamping assembly 100 and the outer wall of the pipeline 10 is used to accommodate the leak and extends along the circumference of the pipeline 10. The plugging mechanism 200 includes a scraping end and a connecting end, one end of the scraping end is arranged on the side of the connecting end facing the leak, and the other end is arranged against the outer wall of the pipeline 10. The connecting end is slidably arranged on the clamping assembly 100 along the guide gap 101 and is connected to the external driving member 300. Driven by the driving member 300, the connecting end rotates around the central axis of the pipeline 10, driving the scraping end to slide along the guide gap 101 and scrape the pipeline repair material applied to the leak. Through the sliding and scraping of the scraping end, the pipeline repair material can fit tightly to the leak, thus achieving non-stop sealing.

[0041] Please continue reading Figures 1 to 3 , and see Figure 4In an embodiment of the present invention, the plugging mechanism 200 includes an upper connecting piece 210, a lower connecting piece 220 and a scraper 230. The upper connecting piece 210 and the lower connecting piece 220 are respectively arranged on opposite sides of the clamping assembly 100 at positions corresponding to the guide gap 101. The upper connecting piece 210 and the lower connecting piece 220 can both rotate around the axis of the pipe 10. The scraper 230 is arranged on one side of the upper connecting piece 210 and / or the lower connecting piece 220 facing the leakage; wherein the scraper 230 forms a scraping end, and the upper connecting piece 210 and the lower connecting piece 220 respectively form connecting ends.

[0042] It should be noted that the scraper 230 is a polytetrafluoroethylene (PTFE) component in the related art, so as to achieve wear resistance and reduce adhesion of pipeline repair materials.

[0043] Specifically, the upper connecting piece 210 and the lower connecting piece 220 are respectively arranged on opposite sides of the clamping assembly 100 at positions corresponding to the guide gap 101. This ensures that the plugging mechanism 200 can be closely matched with the leaking part of the pipeline 10, and uniformly applies pressure along the circumference of the pipeline 10 during the repair process. The upper connecting piece 210 and the lower connecting piece 220 can both rotate around the central axis of the pipeline 10, so that the scraper 230 can scrape the pipeline repair material to the leaking part.

[0044] The scraper 230 can be used to clean the surface of the pipe 10, remove pollutants, rust or old repair materials, so as to provide a smoother and cleaner surface for the application of the repair material, and ensure the durability and reliability of the repair effect. The upper connecting piece 210 and the lower connecting piece 220 can be rotated to drive the scraper 230 to slide along the guide gap 101, so that the scraper end can evenly scrape and clean along the circumference of the leak.

[0045] During the plugging process, the scraper 230 can also make the pipeline repair material evenly distributed on the surface of the leaking part, avoiding the situation where the pipeline repair material cannot fully adhere to the uneven or contaminated surface, resulting in unsatisfactory repair effect. The cooperation between the upper connecting piece 210 and the lower connecting piece 220 and the scraper 230 ensures that the scraper end can closely contact the leaking part during the plugging process, thereby improving the accuracy and reliability of the repair.

[0046] More specifically, the upper connecting piece 210 and the lower connecting piece 220 ensure that the position of the scraper 230 can be adjusted according to the specific conditions of the pipeline 10 during the repair process, thereby improving the adaptability and flexibility of the plugging. The rotational cooperation between the upper connecting piece 210 and the lower connecting piece 220 can drive the scraper 230 to slide circumferentially along the leaking part, effectively cleaning the surface of the pipeline 10 and providing adhesion conditions for the subsequent coating of the repair material.

[0047] The plugging mechanism 200 of this embodiment has a simple structure and is easy to operate. It can quickly repair the leak, avoid stopping the transmission and wasting energy, significantly improve the maintenance efficiency, and reduce the maintenance cost. In addition, the scraping end can improve the repair effect of the pipeline repair material, improve the long-term stability of the pipeline 10 after repair, and further improve the reliability of the repair.

[0048] It should be understood that there may be a plurality of scraping members 230 to further evenly distribute the pipeline repair material at the leaking location.

[0049] Please continue reading Figures 1 to 3 In an embodiment of the present invention, the upper connecting piece 210 and the lower connecting piece 220 are connected to the driving member 300 through an external transmission belt 400, and the transmission belt 400 is wound around the outer walls of the upper connecting piece 210 and the lower connecting piece 220, so that the upper connecting piece 210 and the lower connecting piece 220 are pressed against the circumferential outer wall of the clamping assembly 100.

[0050] Specifically, the transmission belt 400 is wound around the outer wall of the upper connecting piece 210 and the lower connecting piece 220 to ensure that the belt is evenly distributed to avoid being partially too tight or too loose. One end of the transmission belt 400 is connected to the external driving member 300, and the other end is connected to the upper connecting piece 210 and / or the lower connecting piece 220. When the driving member 300 is started, the transmission belt 400 presses the upper connecting piece 210 and the lower connecting piece 220 against the circumferential outer wall of the clamping assembly 100 through its tension. The upper connecting piece 210 and the lower connecting piece 220 rotate around the axis of the pipeline 10 under the drive of the transmission belt 400, and the scraper 230 moves to the leaking part to apply the pipeline repair material.

[0051] It should be understood that the introduction of the transmission belt 400 simplifies the driving method of the upper connecting piece 210 and the lower connecting piece 220, making the driving system more compact and efficient. The uniform tension of the transmission belt 400 ensures that the upper connecting piece 210 and the lower connecting piece 220 can be closely attached to the outer wall of the clamping assembly 100 when rotating, thereby improving the operating stability of the scraper 230. In addition, the common pressing effect of the transmission belt 400 and the circumferential outer wall of the clamping assembly 100 on the upper connecting piece 210 and the lower connecting piece 220 enhances the stability of the upper connecting piece 210 and the lower connecting piece 220 during the plugging operation, and reduces the displacement caused by vibration or external force. The rotation of the upper connecting piece 210 and the lower connecting piece 220 is made more stable, and the scraping end can be more uniform and accurate when applying the repair material.

[0052] Please continue reading Figures 1 to 4 In an embodiment of the present invention, the edges of the upper connecting piece 210 and the lower connecting piece 220 both protrude outward along the axial direction of the pipe 10 to form a flange 240, and the flange 240 is slidably matched with the circumferential outer wall of the clamping assembly 100.

[0053] Specifically, the edges of the upper connecting piece 210 and the lower connecting piece 220 are along the axial direction of the pipe 10 and protrude outward in the horizontal direction to form a flange 240. The flange 240 expands the edge portions of the upper connecting piece 210 and the lower connecting piece 220 outward, thereby increasing the contact area with the clamping assembly 100. The flange 240 is slidably matched with the circumferential outer wall of the clamping assembly 100. The upper connecting piece 210 and the lower connecting piece 220 slide on the circumferential outer wall of the clamping assembly 100 through their flanges 240, thereby enhancing the matching effect and stability with the clamping assembly 100 when the upper connecting piece 210 and the lower connecting piece 220 rotate.

[0054] Please continue reading Figures 1 to 4 In an embodiment of the present invention, the upper connecting piece 210 and the lower connecting piece 220 both have an arc that matches the circumferential outer wall of the clamping assembly 100, and the upper connecting piece 210 and the lower connecting piece 220 are connected to form a non-integral ring structure or a complete ring structure.

[0055] It should be noted that the non-integer ring structure includes gaps or gaps, while the complete ring structure forms a continuous ring.

[0056] Specifically, the upper connecting piece 210 and the lower connecting piece 220 both have a curvature that matches the circumferential outer wall of the clamping assembly 100. The matching curvature enables the upper connecting piece 210 and the lower connecting piece 220 to better fit the circumferential wall of the clamping assembly 100, ensuring stable support during the plugging operation.

[0057] The upper connecting piece 210 and the lower connecting piece 220 are connected to form a non-integer ring structure or a complete ring structure. The non-integer ring structure formed by the upper connecting piece 210 and the lower connecting piece 220 has better stability during the rotation process. The non-integer ring structure formed by the upper connecting piece 210 and the lower connecting piece 220 can better adapt to different application scenarios and pipe 10 sizes.

[0058] In addition, the non-integral ring structure formed by connecting the upper connecting piece 210 and the lower connecting piece 220 enables the upper connecting piece 210 and the lower connecting piece 220 to have a certain degree of elasticity or ductility, so that when the pipeline 10 is deformed or the position of the leakage point changes, it can better adapt and adjust. The complete ring structure provides continuous ring support to ensure the uniformity and consistency of the plugging operation.

[0059] Please continue reading Figures 1 to 4 , and see Figure 5In an embodiment of the present invention, a side of the connection end facing the leakage point is provided with an avoidance groove 201, and the avoidance groove 201 extends radially along the pipe 10; the scraping end is arranged in the avoidance groove 201, and an elastic member 500 is arranged between the scraping end and the bottom wall of the avoidance groove 201; wherein, a slide groove 202 is provided on the inner side wall of the avoidance groove 201 extending radially along the pipe 10, and a slider 231 is connected to the outer wall of the scraping end, and the scraping end slides with the slide groove 202 through the slider 231.

[0060] Specifically, a side of the connection end facing the leaking part is provided with an avoidance groove 201. The avoidance groove 201 extends along the radial direction of the pipeline 10, which enables the scraping end to avoid obstacles or protrusions on the pipeline 10 when approaching the leaking part.

[0061] The scraping end is arranged in the avoidance groove 201, and an elastic member 500 is arranged between the scraping end and the bottom wall of the avoidance groove 201. The function of the elastic member 500 is to buffer the impact of the scraping end when it contacts the pipeline 10, and at the same time keep the scraping end in a stable position in the avoidance groove 201, so that the scraping end can keep against the outer wall of the pipeline 10, thereby ensuring the coating effect of the pipeline repair material. The avoidance groove 201 enables the scraping end to avoid obstacles when approaching the leak, thereby improving the accuracy and safety of the plugging operation.

[0062] The inner wall of the avoidance groove 201 extending radially along the pipe 10 is provided with a slide groove 202, and the outer wall of the scraping end is connected with a slider 231, which slides with the slide groove 202. The scraping end can flexibly adjust its position during the plugging operation, and the scraping end has flexibility and adaptability in the plugging operation.

[0063] Please continue reading Figure 5 In an embodiment of the present invention, a feed port 203 is provided on the outer wall of the connection end, and the feed port 203 is connected to the guide gap 101 through a guide channel 204 in the connection end. The feed port 203 is used to add fluid-like pipeline repair material to the leakage in the guide gap 101.

[0064] It should be noted that the feed port 203 is provided on the outer wall of the connection end to ensure that the feed port 203 is large enough to accommodate a container of pipeline repair material or to directly add the material manually.

[0065] Specifically, a feed port 203 is provided on the outer wall of the connection end. The operator can conveniently introduce the pipeline repair material into the plugging mechanism 200 through the feed port 203. When the pipeline repair material needs to be added, the pipeline repair material is poured into the guide channel 204 through the feed port 203 and guided to the guide gap 101, and finally reaches the leaking part of the outer wall of the pipeline 10. It should be understood that the feed port 203 is used to add fluid pipeline repair material to the leak in the guide gap 101. The fluid pipeline repair material can be resin, glue or other curable materials in the related art, which is used to fill the leak and achieve plugging.

[0066] Please continue reading Figures 1 to 4 In an embodiment of the present invention, the clamping assembly 100 includes two clamping structures 110, and the two clamping structures 110 are spaced along the axial direction of the pipe 10 to form a guide gap 101; each clamping structure 110 includes an upper clamping bar 111 and a lower clamping bar 112, and the upper clamping bar 111 and the lower clamping bar 112 are respectively arranged on opposite sides of the clamping assembly 100, and the upper clamping bar 111 and the lower clamping bar 112 both have an arc that is compatible with the circumferential outer wall of the pipe 10, and the upper clamping bar 111 and the lower clamping bar 112 are detachably connected to form a complete annular structure.

[0067] Specifically, the clamping assembly 100 includes two clamping structures 110. The two clamping structures 110 are spaced apart along the axial direction of the pipe 10 to form a guide gap 101. The guide gap 101 is a path for the scraping end to move, ensuring that it can operate along the axial direction of the pipe 10.

[0068] Each clamping structure 110 includes an upper clamping bar 111 and a lower clamping bar 112. The upper clamping bar 111 and the lower clamping bar 112 are respectively arranged on opposite sides of the clamping assembly 100, and both the upper clamping bar 111 and the lower clamping bar 112 have an arc that matches the circumferential outer wall of the pipe 10. The upper clamping bar 111 and the lower clamping bar 112 can better fit the shape of the pipe 10 and provide a stable clamping force.

[0069] More specifically, the upper clamping bar 111 and the lower clamping bar 112 can be detachably connected together by a connection method in the related art (such as bolts, buckles, etc.), for example, the bottom ends of the upper clamping bar 111 are provided with latches, and the top ends of the lower clamping bar 112 are provided with sockets, and the latches are interference-fitted into the sockets to form a complete annular structure to provide a stable clamping force, ensuring that the scraping end will not fall off the pipe 10 during operation. The detachable connection between the upper clamping bar 111 and the lower clamping bar 112 makes the clamping assembly 100 easy to install and disassemble, and convenient for maintenance and replacement.

[0070] Please continue reading Figure 1 and Figure 2 In an embodiment of the present invention, the clamping assembly 100 also includes a bottom plate 120, a slide rail 130 and a base 140. The side of the lower clamping bar 112 facing away from the pipe 10 is connected to the base 140. The slide rail 130 extends along the axial direction of the pipe 10. The slide rail 130 is connected to the bottom plate 120, and the base 140 is slidably connected to the slide rail 130.

[0071] Specifically, the two clamping structures 110 move away from or close to each other along the guide rail to adjust the size of the guide gap 101 to adapt to leaks of different sizes, and when the size of the guide gap 101 is enlarged, if the flange 240 in a blocking mechanism 200 can no longer contact the peripheral wall of the clamping structure 110, the blocking mechanism 200 is expanded by bonding or clamping multiple blocking mechanisms 200 to meet the blocking size requirements of the leak. After the distance between the two clamping structures 110 is confirmed, the base 140 can be connected to the bottom plate 120 by bolts to fix the clamping structure 110.

[0072] Please continue reading Figures 1 to 5 , and see Figure 6 The present invention also proposes a method for plugging a non-stop pipeline 10, using the non-stop pipeline 10 plugging device as described above, the non-stop pipeline 10 plugging method comprising: Step S10, cleaning the outer wall of the pipeline 10 where the leak is formed to form a section to be blocked; Step S20, moving the clamping assembly 100 to the section to be blocked, and detachably sleeve the clamping assembly 100 on the outer periphery of the blocking section; Step S30, coating the outer wall of the pipeline 10 with a fluid-like pipeline repair material corresponding to the leakage location; Step S40, detachably disposing the connection end of the blocking mechanism 200 in the guide gap 101; Step S50: connecting the connection end of the blocking mechanism 200 to the driving member 300 by using a transmission belt 400; Step S60, start the driving member 300, drive the connecting end to drive the scraping end to rotate along the guide gap 101 around the axis of the pipeline 10, so that the scraping end scrapes the pipeline repair material into the leaking part until the leaking part is sealed.

[0073] Specifically, in step S10, the operator first conducts an on-site inspection of the leaking pipeline 10 to determine the location of the leak. Then, the outer wall of the leak is cleaned with a cleaning tool (such as sandpaper, wire brush, etc.) to remove dirt, rust or old repair materials on the surface, ensuring that the surface of the leak is clean and flat, providing a good foundation for the subsequent coating of the repair material.

[0074] In step S20, the operator moves the clamping assembly 100 (including the upper clamping bar 111 and the lower clamping bar 112) to the position of the pipeline 10 near the leak. Then, the clamping assembly 100 is fixed to the outer periphery of the pipeline 10 through the connecting parts (such as bolts, buckles, etc.) on the clamping assembly 100, ensuring that the clamping assembly 100 is tightly fitted to the outer wall of the pipeline 10, forming a guide gap 101 for accommodating the leak.

[0075] In step S30, the operator uses a coating tool (such as a brush, a spray gun, etc.) to thickly apply the pipeline repair material on the outer wall of the leaking part. The repair material can be resin, glue or other materials that can be solidified and formed, and its purpose is to fill the leaking part and achieve plugging.

[0076] In step S40 , the operator inserts the connection end (including the upper connection piece 210 and the lower connection piece 220 ) of the blocking mechanism 200 into the guide gap 101 to ensure that the connection end can slide freely.

[0077] In step S50, the operator winds the transmission belt 400 around the outer wall of the connection end, and connects one end of the transmission belt 400 to the external driving member 300, and the other end to the connection end. In this way, the driving member 300 can control the movement of the connection end through the transmission belt 400.

[0078] In step S60, when the driving member 300 is started, the connecting end starts to rotate around the axis of the pipe 10, driving the scraping end to slide in the guide gap 101. During the sliding process, the scraping end scrapes the repair material coated on the outer wall of the pipe 10 into the leaking part, ensuring that the repair material can fully fill the leaking part and achieve effective plugging.

[0079] For ease of understanding, a specific implementation scenario is shown here: Taking a leak in a gas pipeline 10 as an example, the operator first conducts an on-site inspection of the leak point to determine the leak location. Subsequently, a cleaning tool is used to clean the outer wall of the leak. Next, the clamping assembly 100 is moved to the vicinity of the leak point and fixed to the outer periphery of the pipeline 10 to form a guide gap 101. In the guide gap 101, the operator applies the pipeline repair material to the outer wall of the leak. Then, the connecting end of the sealing mechanism 200 is inserted into the guide gap 101 and connected to the driving member 300 through the transmission belt 400. After starting the driving member 300, the connecting end drives the scraping end to slide along the guide gap 101, scraping the repair material into the leak until the plugging is completed. During the whole process, the gas transportation in the pipeline 10 is not affected, and the plugging of the pipeline 10 without stopping is achieved.

Since the non-stop pipeline 10 plugging method adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
