Description

Technical Field

[0001] The invention relates to a pipeline emergency treatment device, in particular to a municipal pipeline leakage emergency treatment device applied to the pipeline field. Background Art

[0002] Most pipeline leak-proof devices use a clamp-type method to tighten the pipeline, thereby plugging the leak in the pipeline.

[0003] For example, the specification of patent publication number CN113685651B discloses an emergency treatment device for municipal pipeline leakage, which can be used even when both ends of the pipeline are covered, and can be folded and stored after use, which greatly reduces the floor space and can be recycled, including a foldable outer frame, a buckle device, an adjustment device, and a telescopic plugging device, which is put on the damaged pipeline, the buckle and the buckle spring make the clamping rod stuck, and the adjustment handle makes the handle connected to the bevel gear rotate, adjusting the bevel gear A, adjusting the bevel gear B, the short adjustment shaft A, the short adjustment shaft B, the connecting gear A, the connecting gear B, the connecting gear C, the short adjustment shaft C, the transmission gear A, the transmission gear B, the short adjustment shaft D, the transmission small gear, the transmission large gear, the short adjustment shaft E, and the connecting gear. Gear D, connecting gear E, long adjustment shaft and connecting gear F rotate the telescopic adjustment bevel gear, and the telescopic screw rotates to move the telescopic plugging plate downward to plug the leak. Another example is a municipal pipeline leakage emergency treatment device disclosed in the specification of patent publication number CN116951213A, which includes two relatively arranged mounting frames, one end of one mounting frame is rotatably connected to one end of the other mounting frame, a locking assembly for locking the mounting frame is provided on the mounting frame, and a plurality of moving rods are slidably matched on the mounting frame. One end of the moving rod located in the mounting frame is detachably connected to a tightening arc plate, and a moving assembly for driving all the moving rods to move simultaneously is provided on the mounting frame. When plugging a leaking pipeline, the tightening arc plate presses against the pipeline surface, which has the effect of improving the efficiency of pipeline plugging treatment.

[0004] Based on the above search and in combination with the prior art, it is found that most of the existing emergency treatment devices for pipeline leakage need to be installed on-site, which makes it difficult to deal with emergency situations of pipeline leakage. In addition, the operation of a few plugging devices preset on the pipeline is relatively cumbersome and difficult to plug the leak quickly. Therefore, a municipal pipeline leakage emergency treatment device is proposed to improve the above problems. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that most of the existing pipeline leakage emergency treatment devices need to be installed on-site, which is difficult to deal with emergency situations of pipeline leakage. The few leak-proof devices preset on the pipeline are relatively cumbersome to operate and difficult to quickly plug the leak.

[0006] In order to solve the above problems, the present invention provides a municipal pipeline leakage emergency treatment device, including a preset leak-proof device sleeved on the outside of the pipeline:

[0007] The preset plugging device includes a pipe sleeve sleeved on the outside of the pipeline, and a plurality of plugging units evenly installed around the pipe sleeve;

[0008] The plugging unit includes a plugging arc block, an operating handle and a telescopic assembly;

[0009] The pipe sleeve is provided with a connection hole for installing the telescopic assembly, the operating handle is installed at the end of the telescopic assembly located outside the pipe sleeve, and the leak-proof arc block is installed at the end of the telescopic assembly located inside the pipe sleeve;

[0010] A transmission structure is installed between the multiple telescopic components, so that when any operating handle is rotated, the multiple telescopic components will telescope synchronously.

[0011] In the above-mentioned municipal pipeline leakage emergency treatment device, the pipe sleeve can slide on the pipeline, and the preset leak-proof device can be quickly moved to the leakage part of the pipeline. Through the cooperation of the leak-proof arc block, the operating handle and the telescopic assembly, when any one of the operating handles is turned, multiple telescopic assemblies telescope synchronously, thereby achieving rapid sealing of the pipeline leakage part.

[0012] As a further supplement to the present application, the telescopic assembly includes a transmission sleeve and a threaded rod;

[0013] The transmission sleeve is rotatably installed on the inner side of the connecting hole, the end of the transmission sleeve located outside the pipe sleeve is connected to the operating handle, the end of the transmission sleeve away from the operating handle is provided with a thread groove threadedly connected to the threaded rod, and the end of the threaded rod located outside the thread groove is fixed to the plugging arc block;

[0014] The transmission structure is installed between the transmission sleeve and the pipe sleeve;

[0015] A limiting sliding column is fixed to the end face of the leak-proof arc block close to the threaded rod, and a limiting sliding hole that slides with the limiting sliding column is provided on the inner wall of the pipe sleeve; when the operating handle is rotated, the operating handle drives the transmission sleeve to rotate, and under the cooperation of the threaded rod and the threaded groove, the limiting sliding column and the limiting sliding hole, the threaded rod drives the leak-proof arc block to move along the radial direction of the pipeline.

[0016] As a further supplement to the present application, the transmission structure includes a bevel gear ring and a plurality of bevel gears;

[0017] The bevel gear ring is rotatably sleeved on the outside of the pipe sleeve, and multiple bevel gears are coaxially fixedly sleeved on the outside of multiple transmission sleeves in a one-to-one correspondence, and all are meshed with the bevel gear ring; under the meshing action of the bevel gear ring and the multiple bevel gears, when any operating handle is rotated, the multiple transmission sleeves rotate synchronously, thereby driving the multiple plugging arc blocks to move synchronously along the radial direction of the pipeline, thereby achieving rapid plugging of the pipeline leakage.

[0018] As a further supplement to the present application, a protective shell is sleeved on the outer side of the pipe sleeve, the bevel gear and the bevel gear ring are both located on the inner side of the protective shell, and the threaded rod passes through the protective shell.

[0019] As another improvement of the present application, a plurality of limit tooth blocks are equidistantly and integrally arranged on the circumferential side of the end surface of the operating handle close to the transmission sleeve, and a limit plate engaged with two adjacent limit tooth blocks is fixed on the outer surface of the sleeve;

[0020] A limit slider is fixed to the end of the operating handle close to the transmission sleeve, and a limit slot matching the limit slider is provided at the end of the transmission sleeve, and a tension spring is fixed between the limit slider and the limit slot; the limit tooth block is engaged with the limit plate, which can effectively prevent the operating handle from accidentally rotating without human intervention. When the operating handle needs to be rotated, the operating handle is manually pulled outward. When the limit tooth block and the limit plate are in a separated state, the operating handle is rotated to drive multiple telescopic components to telescope synchronously.

[0021] As another improvement of the present application, a plurality of movable wheel groups are equidistantly installed on the circumference of the inner wall of the pipe sleeve, and two annular cleaning brushes are installed on the inner side of the pipe sleeve, and the two annular cleaning brushes are respectively located on both sides of the leak-plugging arc block; the arranged annular cleaning brushes can clean the surface of the pipeline during the process of the pipe sleeve sliding on the pipeline, so as to prevent impurities attached to the surface of the pipeline from affecting the fit between the leak-plugging arc block and the surface of the pipeline, thereby improving the leak-plugging effect.

[0022] As a further improved supplement of the present application, the moving wheel set includes a wheel frame, a spherical wheel and a compression spring;

[0023] The spherical wheel is movably installed on the inner side of the wheel frame, and a limiting groove for sliding installation of the wheel frame is arranged on the inner wall of the pipe sleeve. The wheel frame and the limiting groove are fixed by a compression spring. The spherical wheel is arranged to facilitate the flexible movement of the pipe sleeve on the pipeline, and the compression spring can make the movement of the pipe sleeve on the pipeline more flexible.

[0024] As another improvement of the present application, a winding box is installed on one side of the pipe sleeve, and a sealing belt is installed on the inner side of the winding box through a disc spring, and one end of the sealing belt passes through the winding box; in the case of a long leakage crack in the pipeline, the sealing belt can be pulled outward, wrapped around the leakage crack, and the two ends of the sealing belt can be fixed relative to the pipeline.

[0025] In summary, the spherical wheel is convenient for flexibly moving the pipe sleeve on the pipeline, and the preset leak-proof device can be quickly moved to the leaking part of the pipeline. Through the cooperation of the leak-proof arc block, the operating handle and the telescopic assembly, when any one of the operating handles is turned, multiple telescopic assemblies are synchronously telescoped, thereby realizing rapid sealing of the leaking part of the pipeline; and the annular cleaning brush is arranged to clean the surface of the pipeline during the sliding of the pipe sleeve on the pipeline, so as to prevent impurities attached to the surface of the pipeline from affecting the fit between the leak-proof arc block and the surface of the pipeline, thereby improving the leak-proof effect; for the case where the leakage crack of the pipeline is long, the sealing tape can be pulled outward and wrapped around the leakage crack, and the two ends of the sealing tape can be fixed relatively to the pipeline, and at the same time, the two preset leak-proof devices are respectively moved and fixed on both sides of the longer crack on the pipeline, and the pipelines on both sides of the longer crack are externally supported, which can effectively prevent the crack from expanding. The overall structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is a detailed description of four implementation methods of the present application in conjunction with the accompanying drawings.

[0038] The first implementation method:

[0039] The present invention provides a municipal pipeline leakage emergency treatment device, please refer to Figure 1-6 , including a preset plugging device 1 sleeved on the outside of the pipeline, the preset plugging device 1 includes a pipe sleeve 11 sleeved on the outside of the pipeline, and a plurality of plugging units evenly installed on the periphery of the pipe sleeve 11.

[0040] The leak-plugging unit includes a leak-plugging arc block 12, an operating handle 13 and a telescopic assembly 14. A connecting hole 1101 for installing the telescopic assembly 14 is provided on the pipe sleeve 11. The operating handle 13 is installed at the end of the telescopic assembly 14 located on the outside of the pipe sleeve 11. The leak-plugging arc block 12 is installed at the end of the telescopic assembly 14 located on the inside of the pipe sleeve 11. A transmission structure is installed between the multiple telescopic assemblies 14 so that when any operating handle 13 is rotated, the multiple telescopic assemblies 14 telescope synchronously.

[0041] The municipal pipeline leakage emergency treatment device is provided with a preset plugging device 1 on the outside of the pipeline. The pipe sleeve 11 can slide on the pipeline, and the preset plugging device 1 can be quickly moved to the leakage part of the pipeline. Through the cooperation of the plugging arc block 12, the operating handle 13 and the telescopic component 14, when any one of the operating handles 13 is turned, multiple telescopic components 14 are synchronously telescoped, thereby realizing rapid plugging of the pipeline leakage part.

[0042] Regarding the telescopic component 14, specifically, Figure 6It is shown that the telescopic assembly 14 includes a transmission sleeve 141 and a threaded rod 142. The transmission sleeve 141 is rotatably installed on the inner side of the connecting hole 1101. The end of the transmission sleeve 141 located on the outer side of the pipe sleeve 11 is connected to the operating handle 13. The end of the transmission sleeve 141 away from the operating handle 13 is provided with a thread groove 1401 threadedly connected to the threaded rod 142. The end of the threaded rod 142 located on the outer side of the thread groove 1401 is fixed to the leak-proof arc block 12. The transmission structure is installed between the transmission sleeve 141 and the pipe sleeve 11. A limiting sliding column 16 is fixed to the end face of the leak-proof arc block 12 close to the threaded rod 142. A limiting sliding hole 1102 that slides with the limiting sliding column 16 is provided on the inner wall of the pipe sleeve 11.

[0043] Based on the coordination setting of the above structure, when the operating handle 13 is rotated, the operating handle 13 rotates with the transmission sleeve 141, and under the coordination of the threaded rod 142 and the threaded groove 1401, the limiting sliding column 16 and the limiting sliding hole 1102, the threaded rod 142 moves with the leak-proof arc block 12 along the radial direction of the pipeline.

[0044] Among them, regarding the transmission structure, specifically, Figure 5 As shown, the transmission structure includes a bevel gear ring 18 and multiple bevel gears 17. The bevel gear ring 18 is rotatably sleeved on the outside of the pipe sleeve 11, and the multiple bevel gears 17 are coaxially fixedly sleeved on the outside of multiple transmission sleeves 141 one by one, and are all meshed with the bevel gear ring 18.

[0045] Under the meshing action of the bevel gear ring 18 and the multiple bevel gears 17, when any operating handle 13 is rotated, the multiple transmission sleeves 141 rotate synchronously, thereby driving the multiple leak-proof arc blocks 12 to move synchronously along the radial direction of the pipeline, thereby achieving rapid plugging of pipeline leaks.

[0046] The outer side of the pipe sleeve 11 is sleeved with a protective shell 110 , the bevel gear 17 and the bevel gear ring 18 are both located on the inner side of the protective shell 110 , and the threaded rod 142 passes through the protective shell 110 , which protects the bevel gear 17 and the bevel gear ring 18 .

[0047] Second implementation method:

[0048] Based on the first embodiment, the present embodiment adds the following structure, so that the present application can effectively prevent the operating handle 13 from being accidentally rotated by humans. The specific configuration is as follows: Figure 6 and Figure 7As shown, a plurality of limit tooth blocks 1302 are equidistantly and integrally arranged on the circumferential side of the end surface of the operating handle 13 close to the transmission sleeve 141, a limit plate engaged with two adjacent limit tooth blocks 1302 is fixed to the outer surface of the pipe sleeve 11, a limit slider 1301 is fixed to the end of the operating handle 13 close to the transmission sleeve 141, a limit slot 1402 matched with the limit slider 1301 is arranged at the end of the transmission sleeve 141, and a tension spring 112 is fixed between the limit slider 1301 and the limit slot 1402.

[0049] The limit tooth block 1302 is engaged with the limit plate, which can effectively prevent the operating handle 13 from rotating unexpectedly without human intervention. When the operating handle 13 needs to be rotated, the operating handle 13 is manually pulled outward. When the limit tooth block 1302 and the limit plate are separated, the operating handle 13 is rotated to drive multiple telescopic components 14 to perform synchronous telescopic movements.

[0050] The third implementation method:

[0051] This embodiment adds the following structure on the basis of Embodiment 1 and Embodiment 2, so that the present application can improve the fit between the plugging arc block 12 and the pipeline surface, and the specific configuration is as follows: Figure 3 As shown, two annular cleaning brushes 19 are installed on the inner side of the pipe sleeve 11 , and the two annular cleaning brushes 19 are respectively located on both sides of the plugging arc block 12 .

[0052] The annular cleaning brush 19 can clean the surface of the pipeline when the sleeve 11 slides on the pipeline, so as to prevent impurities attached to the pipeline surface from affecting the fit between the plugging arc block 12 and the pipeline surface, thereby improving the plugging effect.

[0053] A plurality of moving wheel groups 15 are equidistantly mounted on the inner wall circumference of the pipe sleeve 11. Regarding the moving wheel groups 15, specifically, Figure 8 As shown, the movable wheel group 15 includes a wheel frame 151, a spherical wheel 152 and a compression spring 153. The spherical wheel 152 is movably installed on the inner side of the wheel frame 151. A limiting groove 1103 for sliding installation of the wheel frame 151 is provided on the inner wall of the sleeve 11. The wheel frame 151 and the limiting groove 1103 are fixed by the compression spring 153.

[0054] The spherical wheel 152 is provided to facilitate the flexible movement of the pipe sleeve 11 on the pipeline, and the compression spring 153 is provided to make the movement of the pipe sleeve 11 on the pipeline more flexible.

[0055] The fourth implementation method:

[0056] This embodiment adds the following structure on the basis of Embodiment 1, Embodiment 2 and Embodiment 3, so that the present application can effectively plug the long leakage cracks in the pipeline, and the specific configuration is as follows: Figure 3 and Fig. 9 As shown, a reel box 111 is installed on one side of the pipe sleeve 11, and a sealing belt is installed on the inner side of the reel box 111 through a disc spring (not shown in the figure). One end of the sealing belt passes through the reel box 111. Through the setting of the disc spring, the sealing belt can be automatically stored in the reel box 111 after the pipeline leakage is repaired at a later stage. The sealing belt adopts the waterproof and corrosion-resistant material in the prior art, which is specifically determined according to the material of the pipeline and the substance passing through the inside of the pipeline.

[0057] In the case of a long leaking crack in the pipeline, the sealing tape can be pulled outward, wrapped around the leaking crack, and the two ends of the sealing tape can be fixed relative to the pipeline.

[0058] Working principle: During the installation of the pipeline, at least two preset leak-blocking devices 1 are sleeved on the outer side of the pipeline between two adjacent support seats (the support seats are fixed on the external installation surface, such as the wall) for supporting the pipeline (the specific number of the preset leak-blocking devices 1 is determined according to the distance between the two adjacent support seats, and the longer the distance, the greater the number);

[0059] When a pipeline leaks, personnel use the spherical wheel 152 on the preset plugging device 1 to flexibly move the pipe sleeve 11 on the pipeline, and can quickly move the preset plugging device 1 to the leaking part of the pipeline. In addition, the annular cleaning brush 19 can clean the surface of the pipeline during the sliding of the pipe sleeve 11 on the pipeline to prevent impurities attached to the pipeline surface from affecting the fit between the plugging arc block 12 and the pipeline surface, thereby improving the plugging effect. Manually pull the operating handle 13 outwards, rotate the operating handle 13 when the limit tooth block 1302 is separated from the limit plate, and rotate the operating handle 13 when the conical gear ring 18 is connected to the plurality of conical gear rings. Under the meshing action of the gear 17, when any one of the operating handles 13 is rotated, the multiple transmission sleeves 141 rotate synchronously. Under the cooperation of the threaded rod 142 and the threaded groove 1401, the limiting slide column 16 and the limiting slide hole 1102, the rotating transmission sleeve 141 causes the threaded rod 142 to move along the radial direction of the pipeline with the leak-blocking arc block 12 until the leak-blocking arc block 12 blocks the leaking part of the pipeline. The operating handle 13 is released. Under the action of the tension spring 112, the limiting tooth block 1302 approaches and engages with the limiting plate, which can effectively prevent the operating handle 13 from being rotated unintentionally by humans.

[0060] In the case of a long leakage crack in the pipeline, the sealing tape can be pulled outward, wrapped around the leakage crack, and the two ends of the sealing tape can be fixed relative to the pipeline; in addition, for an installation environment where the pipeline is close to the wall, the sealing tape can be quickly wrapped around the pipeline by rotating the preset leak-proof device 1 as a whole, and the two preset leak-proof devices 1 can be moved and fixed to the two sides of the longer crack on the pipeline respectively, and the pipelines on both sides of the longer crack can be externally supported, which can effectively prevent the crack from expanding.

[0061] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
