Description

Technical Field

[0001] This application belongs to the field of pipeline repair technology, specifically relating to a rapid water-stopping device for urban stormwater and sewage pipelines based on in-situ solidification method. Background Technology

[0002] Urban stormwater and sewage pipe networks are part of urban infrastructure, used to collect and transport rainwater and sewage. In-situ solidification is a trenchless repair technology used to repair old or damaged stormwater and sewage pipe networks. It eliminates the need for large-scale excavation during construction, reducing the impact on the ground and traffic, and features short construction time and high durability of the repaired pipe network.

[0003] In existing technologies, rapid water-stopping operations on the inner wall of pipelines using in-situ curing methods mainly rely on manual labor. Specifically, workers push a trolley into the pipeline, which is loaded with a storage tank and a spraying device connected to the storage tank. When the trolley moves to the repair area, the workers hold the end of the spraying device and spray it at the water outlet on the inner wall of the pipeline to achieve rapid repair of the pipeline and achieve the purpose of water-stopping.

[0004] The inventors discovered that during the construction of the inner wall of a pipe network, the distance between the spray nozzle and the inner wall directly affects the water-stopping effect. Specifically: when the distance between the spray nozzle and the inner wall is close, the area of ​​sprayed material adhering to the pipe network is small. Due to the limited accuracy of operators in manipulating the spray nozzle, the material is insufficient to cover the water outlets, resulting in the inner wall of the pipe network failing to stop the water flow. On the other hand, when the distance between the spray nozzle and the inner wall is greater, although the spraying area increases, the force exerted by the material on the inner wall decreases. In this case, because liquid continuously flows out from the water outlets on the inner wall, the liquid will create convection with the sprayed material, easily offsetting the movement of the material, also resulting in the inner wall of the pipe network failing to stop the water flow. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0019] The bottom of the guide groove has a through hole extending to the lower side of the positioning platform and along the length of the guide groove. A slider that passes through the through hole and extends out is fixedly connected to the positioning seat, and the slider abuts against the lower side of the positioning platform to prevent the positioning seat from disengaging from the guide groove.

[0020] In one possible implementation, the linear drive component includes:

[0021] A transmission screw is rotatably mounted on the lower side of the positioning platform, and both its axial direction and rotational direction are parallel to the length direction of the guide groove; the transmission screw is driven by a first rotary motor for rotating it; and

[0026] In one possible implementation, the lower end face of the docking shell is provided with a lower insertion hole that communicates with the liquid storage chamber and is coaxially arranged with the upper insertion hole;

[0027] The upper end face of the positioning seat has a groove coaxially connected with the lower insertion hole, and the rotation drive component is a second rotation motor fixedly installed in the groove;

[0028] The power output axis of the second rotating motor is parallel to the vertical direction, and its power output shaft is connected to the main shaft through the lower insertion hole. The outer peripheral surface of the second rotating motor is in contact with the inner peripheral surface of the lower insertion hole.

[0038] Before starting the discharge pump, the distance between the spraying end and the top wall of the pipeline can be changed by manually adjusting the adjustable support component. Based on this, the relative position of the adjusting plate and the main shaft can be pre-adjusted to make the first and second strip holes partially or completely connected, thereby changing the coverage area of ​​the material.

[0039] After the discharge pump is started, the linear drive component drives the positioning seat to move back and forth in the horizontal direction, while the rotary drive component drives the main shaft to rotate, which can further increase the coverage area of ​​the material.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] Please refer to the following: Figures 1 to 17 The present application describes a rapid water-stopping device for urban stormwater and sewage pipe networks based on in-situ curing. The rapid water-stopping device for urban stormwater and sewage pipe networks based on in-situ curing proposed in this application includes a traveling vehicle 10, a positioning platform 1, a docking shell 2, a main shaft 3, and an adjusting plate 4.

[0065] The traveling vehicle 10 is used to move within the pipeline network and typically adopts a trolley structure with four wheels. Based on this, a storage tank 20 for holding materials is fixedly installed on the vehicle plate of the traveling vehicle 10. In order to discharge the materials, the storage tank 20 is also connected to a discharge pump 201 for discharging the materials.

[0066] It should be noted that, in this embodiment, the material stored in the storage tank 20 usually refers to cement-based or chemical grouting materials. These materials have the function of covering the inner wall of the pipeline and quickly stopping water. Common types include cement-based grout, polyurethane grout, epoxy resin grout and acrylate grout.

[0067] Cement-based grouts consist of cement, a quick-setting agent (such as calcium chloride), and water, and solidify rapidly after mixing. Polyurethane grouts are produced by the reaction of isocyanates and polyols, expand upon contact with water, and are suitable for dynamic aquatic environments. Epoxy resin grouts consist of epoxy resin and a curing agent, and have high strength after curing, making them suitable for structural repair. Acrylic grouts are polymerized from acrylate monomers, have strong penetration, and are used for small cracks.

[0068] It should be further clarified that cement-based slurries are prepared by mixing dry powders such as cement and accelerators, and water needs to be added and stirred before use. Polyurethane slurries are prepared by separately producing isocyanate and polyol components, which are then mixed in a specific ratio before use. Epoxy resin slurries are prepared by separately producing epoxy resin and curing agent, which are then mixed before use. Acrylic slurries are prepared by producing acrylate monomer solutions, and an initiator needs to be added before use.

[0069] The positioning platform 1 is located on the upper side of the traveling vehicle 10 and is connected to the upper side of the traveling vehicle 10 through an adjustable support member 5; a positioning seat 11 is slidably connected to the positioning platform 1 in the horizontal direction, and the positioning seat 11 is connected to a linear drive member 6 for driving its movement.

[0070] The docking shell 2 is fixedly mounted on the alignment seat 11 and has a liquid storage chamber 21. A flexible hose 22 is connected to the docking shell 2 and communicates with the liquid storage chamber 21. The flexible hose 22 is also connected to the discharge pump 201 so that when the discharge pump 201 is started, the material enters the liquid storage chamber 21 through the flexible hose 22. An upper insertion hole 23 is provided on the upper end face of the docking shell 2, which is coaxially arranged with it and also communicates with the liquid storage chamber 21.

[0071] The main shaft 3 is coaxially inserted into the aforementioned upper insertion hole 23, with its outer circumferential surface contacting the inner circumferential surface of the upper insertion hole 23 to restrict the passage of liquid. The main shaft 3 is driven by a rotation drive member 34 for rotating it relative to the docking shell 2. The main shaft 3 has a drainage chamber 31, and a plurality of liquid passage holes 32 are provided on its outer circumferential surface at intervals along its circumference. After the main shaft 3 is inserted into the upper insertion hole 23, these liquid passage holes 32 can connect the drainage chamber 31 and the liquid storage chamber 21. Furthermore, a first strip-shaped hole 33 is provided on the upper end face of the main shaft 3. This first strip-shaped hole 33 communicates with the drainage chamber 31 and extends outward along the radial direction of the main shaft 3.

[0072] The adjusting plate 4 is coaxially disposed on the upper side of the main shaft 3 and fits against the upper end face of the main shaft 3 to facilitate rotation about the main shaft 3. Based on this, a locking structure 7 is provided between the adjusting plate 4 and the main shaft 3, which connects the adjusting plate 4 and the main shaft 3 to restrict the rotation of the adjusting plate 4 relative to the main shaft 3. Furthermore, the adjusting plate 4 is provided with a second strip-shaped hole 41 communicating with the first strip-shaped hole 33. This second strip-shaped hole 41 extends radially outward along the adjusting plate 4. As the adjusting plate 4 rotates relative to the main shaft 3, the communication relationship between the second strip-shaped hole 41 and the first strip-shaped hole 33 switches between partial and complete communication.

[0073] Based on the aforementioned technical solutions, such as Figure 17 As shown, when the first strip-shaped hole 33 and the second strip-shaped hole 41 are partially connected, the first strip-shaped hole 33 and the second strip-shaped hole 41 combine to form a first discharge channel coaxially arranged with the main shaft 3; as Figure 16As shown, when the first strip hole 33 and the second strip hole 41 are connected as a whole, the first strip hole 33 and the second strip hole 41 combine to form a strip-shaped second discharge channel, and the size of the second discharge channel is larger than the size of the first discharge channel.

[0074] In this embodiment, the worker pushes the traveling vehicle 10, which moves the traveling vehicle 10 to below the repair area on the inner wall of the pipeline; then, the material in the storage tank 20 can be discharged by the discharge pump 201, so that it enters the docking shell 2 through the hose 22, and finally enters the discharge chamber 31 through the liquid passage 32, and is discharged to the top from the interconnected first strip hole 33 and second strip hole 41.

[0075] Before the discharge pump 201 is started, the distance between the spraying end and the top wall of the pipeline can be changed by manually adjusting the adjustable support component 5. Based on this, the relative position of the adjusting plate 4 and the main shaft 3 can be pre-adjusted so that the first strip hole 33 and the second strip hole 41 can be partially or completely connected to change the coverage of the material.

[0076] After the discharge pump 201 is started, the linear drive component 6 drives the positioning seat 11 to move back and forth in the horizontal direction, and at the same time, the rotation drive component 34 drives the main shaft 3 to rotate, which can further increase the coverage area of ​​the material.

[0077] The rapid water-stopping device for urban stormwater and sewage pipe networks based on in-situ curing method provided in this embodiment, compared with the prior art, can achieve rapid water-stopping at the outlet of stormwater and sewage pipe networks while ensuring that the distance between the spray tip and the inner wall of the pipe network remains unchanged.

[0078] In some embodiments, such as Figure 2 and Figure 6 As shown, the adjustable support member 5 includes a sleeve 51 and a rod 52.

[0079] The sleeve 51 is fixedly mounted on the traveling vehicle 10, and its axis is parallel to the vertical direction; the outer wall of the sleeve 51 has a plurality of positioning holes 511 spaced apart along the vertical direction, each positioning hole 511 is through in the horizontal direction and communicates with the interior of the sleeve 51.

[0080] The insertion rod 52 is slidably inserted into the sleeve 51 in the up-down direction, and its upper end is fixedly connected to the lower side of the positioning table 1; the insertion rod 52 has an alignment hole 521 suitable for communicating with any of the positioning holes 511.

[0081] The insertion rod 52 has a limiting screw 522; the limiting screw 522 is suitable for insertion into the interconnected positioning hole 511 and alignment hole 521, and both ends of the limiting screw 522 are threaded with limiting nuts 523; after installation and assembly, the two limiting nuts 523 respectively abut against both sides of the sleeve 51.

[0082] In some embodiments, such as Figure 5 As shown, the upper side of the positioning platform 1 is provided with a guide groove 12 extending in the horizontal direction, and the seat 11 is slidably disposed in the guide groove 12 to achieve its sunken installation relative to the positioning platform 1.

[0083] Based on this, the bottom of the guide groove 12 is provided with a through hole 13 that extends through to the lower side of the positioning table 1 and along the length of the guide groove 12. A slider 111 that passes through the through hole 13 and extends out is fixedly connected to the positioning seat 11, and the slider 111 abuts against the lower side of the positioning table 1 to prevent the positioning seat 11 from disengaging from the guide groove 12.

[0084] In some embodiments, such as Figure 5 and Figure 7 As shown, the linear drive component 6 includes a transmission screw 61 and a transmission nut 62.

[0085] The transmission screw 61 is rotatably mounted on the lower side of the positioning table 1, and its axial direction and rotational direction are both parallel to the length direction of the guide groove 12. In order to realize the rotation of the transmission screw 61 relative to the positioning table 1, the transmission screw 61 is connected to the first rotating motor 8.

[0086] The transmission nut 62 is fixedly mounted on the slider 111 and is threadedly connected to the transmission screw 61.

[0087] By adopting the above technical solution, when the first rotating motor 8 starts, the transmission screw 61 rotates so as to drive the slider 111 to move through the transmission nut 62.

[0088] In some embodiments, as shown in the figure Figure 7 and Figure 8 As shown, a driven gear 611 is coaxially connected to the transmission screw 61; the first rotating motor 8 is fixedly mounted on the positioning table 1, and its power output axis is parallel to the axis of the transmission screw 61, and the power output end of the first rotating motor 8 is coaxially connected to a driving gear 81 that meshes with the driven gear 611.

[0089] In some embodiments, such as Figure 9 As shown, the slider 111 has a mounting hole 1111 that extends through the transmission screw 61 along the axial direction, and the transmission nut 62 is fixedly embedded in the mounting hole 1111.

[0090] In some embodiments, such as Figure 5 and Figure 10 As shown, the lower end face of the docking shell 2 is provided with a lower insertion hole 24 that communicates with the liquid storage chamber 21 and is coaxially arranged with the upper insertion hole 23.

[0091] The upper end face of the mounting base 11 has a groove 112 that is coaxially connected with the lower insertion hole 24, and the rotation drive component 34 is a second rotation motor that is fixedly installed in the groove 112.

[0092] Based on this, the power output axis of the second rotating motor is parallel to the vertical direction, and its power output shaft is connected to the main shaft 3 through the lower insertion hole 24, and the outer peripheral surface of the second rotating motor is connected to the inner peripheral surface of the lower insertion hole 24.

[0093] In some embodiments, such as Figure 15 As shown, the adjusting plate 4 and the main shaft 3 are coaxially rotatably connected, and the locking structure 7 includes two lower through holes 71, two upper through holes 72 and two positioning nuts 73.

[0094] Both lower through holes 71 are opened on the upper end face of the main shaft 3 and are connected to the drain cavity 31.

[0095] Both upper through holes 72 are provided on the adjusting plate 4, and both are through in the vertical direction. The two upper through holes 72 are adapted to communicate with the two lower through holes 71 respectively.

[0096] It should be further explained that by rotating the adjusting plate 4 relative to the main shaft 3, the first strip hole 33 and the second strip hole 41 can be connected either entirely or partially. Specifically, when the first strip hole 33 and the second strip hole 41 are fully connected, the first lower through hole 71 and the first upper through hole 72 are connected, and the second lower through hole 71 and the second upper through hole 72 are connected. However, when the first strip hole 33 and the second strip hole 41 are partially connected, and the length direction of the first strip hole 33 is parallel to the length direction of the second strip hole 41, the first lower through hole 71 and the second upper through hole 72 are connected, and the second lower through hole 71 and the first upper through hole 72 are connected.

[0097] Both positioning nuts 73 are fixedly mounted on the adjusting plate 4 and are respectively connected to the two upper through holes 72; each positioning nut 73 is threaded with a locking bolt 731, and the locking bolt 731 is adapted to be screwed downward into the corresponding lower through hole 71 to restrict the rotation of the adjusting plate 4 relative to the main shaft 3.

[0098] In some embodiments, such as Figure 15 As shown, the outer circumferential surface of the adjusting plate 4 is provided with an upper annular groove 42, and the outer circumferential surface of the main shaft 3 is provided with a lower annular groove 35.

[0099] In this embodiment, the rapid water-stopping device for urban stormwater and sewage pipe networks based on the in-situ curing method also includes a connecting ring 9. This connecting ring 9 is sleeved on the outer periphery of the main shaft 3 and the adjusting plate 4, and its inner circumferential surface has two protrusions 91 that are respectively embedded in the upper annular groove 42 and the lower annular groove 35.

[0100] Normally, this connecting ring 9 is made of rubber material and has a certain thickness to ensure the stability of the rotational connection between the adjusting plate 4 and the main shaft 3.

[0101] In some embodiments, such as Figure 7 and Figure 10 As shown, the docking shell 2 also includes multiple connecting arms 25.

[0102] Multiple connecting arms 25 are arranged circumferentially around the docking shell 2. Each connecting arm 25 is fixedly connected to the lower side of the docking shell 2, and each connecting arm 25 extends downward to be adapted to abut against the outer peripheral surface of the alignment seat 11. This facilitates limiting the relative position of the docking shell 2 and the alignment seat 11, and the relative position of the docking shell 2 and the alignment seat 11 can be fixed by welding, bonding or snapping.

[0103] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
