Description

Technical Field

[0001] This utility model belongs to the field of pipeline repair technology, and specifically relates to a pipeline repair device with anti-slip multi-seal. Background Technology

[0002] Plastic pipes are widely used in urban fluid transport networks due to their corrosion resistance and ease of construction; however, pipe damage is a frequent problem. When pipes develop cracks, perforations, or other damage, they must be quickly sealed using repair kits to prevent leaks, pressure losses, and other malfunctions.

[0003] Existing pipeline repair technologies have the following main shortcomings:

[0004] Insufficient sealing reliability: Traditional repair kits mostly use a single-seal structure. When the pressure at the pipe rupture point is high or the surface is uneven, the seal is prone to failure, leading to secondary leakage. Although some repair kits have multiple seals, their complex structure makes precise alignment difficult during installation. Utility Model Content

[0005] This utility model addresses the problems of existing technologies by providing a pipe repair device with anti-slip multi-seal features. The specific technical solution is as follows:

[0006] A pipe repairer with anti-slip multi-seal features includes two half-modules that cooperate to clamp the pipe and form a sealed chamber that connects to the damaged area.

[0007] The semi-module includes a semi-arc plate and a sealing gasket installed in the semi-arc plate. The sealing gasket includes a straight portion and an arc portion. The straight portion is arranged in two sets in parallel along the radial direction, and the arc portion is arranged in two sets in parallel along the axial direction. The two sets of arc portions are connected between the two sets of straight portions.

[0008] In the installed state, the two semi-circular plates cooperate to form a cylindrical structure that surrounds the pipe. The two arc-shaped parts are located on both sides of the damaged area and are deformed by compression to seal the gap between the cylindrical structure and the pipe.

[0009] As a further technical solution of this utility model, the arc-shaped part includes a double-groove pad and a single-groove pad, which are spaced upward along the axial direction. In the installed state, the space forms a temporary chamber that isolates the damaged area from the outside.

[0010] As a further technical solution of this utility model, the inner side of the double groove pad has radially upward extending ribs. In the installation state, the ribs are deformed by compression and adhere to the outer surface of the pipe.

[0011] As a further technical solution of this utility model, the semi-arc plate includes a sealing groove for installing a sealing gasket, wherein the sealing groove includes a straight groove, an arc-shaped double groove and an arc-shaped single groove. In the installation state, the straight part is installed in the straight groove, the double groove gasket is installed in the arc-shaped double groove, and the single groove gasket is installed in the arc-shaped single groove.

[0012] As a further technical solution of this utility model, an extension is provided on both end faces of the semi-arc plate, and the inner side of the extension has a radially extending anti-slip ridge. In the installed state, the anti-slip ridge presses against the outer wall of the pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) Innovative design of multi-seal structure;

[0015] The combination of double-groove and single-groove gaskets: The arc-shaped portion of the sealing gasket uses alternating double-groove and single-groove gaskets to form a multi-layer sealing system of "double groove + single groove". During installation, the two sets of arc-shaped portions are located on both sides of the pipe damage point. After compression, they deform and seal the gap. At the same time, the interval between the two forms a temporary chamber, which can play a secondary interception role when the main seal fails, overcoming the limitations of traditional single-layer seals.

[0016] Ribs enhance sealing performance: The radial ribs on the inner side of the double-groove gasket contact the pipe before the sealing surface. After being squeezed, they deform and adhere to the pipe surface. By increasing the contact pressure and sealing area, the reliability of the seal is improved, which is especially suitable for pipes with uneven surfaces.

[0017] (2) Mechanical optimization of the anti-slip structure;

[0018] The synergistic effect of the extension and anti-slip ridges: Radial anti-slip ridges are provided on the inner side of the extension of the semi-circular plate end face. During installation, these ridges press against the outer wall of the pipe, increasing friction to prevent axial slippage of the repair tool. This design solves the slippage problem of traditional repair tools caused by water pressure or external forces, improving installation stability.

[0019] (3) Precise fit between the sealing groove and the sealing gasket;

[0020] Partitioned sealing groove design: The sealing grooves within the semi-circular plate are divided into straight grooves, double-groove arcs, and single-groove arcs, corresponding to the straight portion, double-groove gasket, and single-groove gasket, respectively. This modular design ensures the gasket's position is fixed after installation, preventing displacement, while also guaranteeing a flat mating surface of the semi-circular plate, thus optimizing overall sealing performance.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] Figure 1 A schematic diagram of the overall structure of a pipe repair tool with anti-slip multi-seal is shown; Figure 1 The present invention relates to a multi-seal anti-slip pipe repair device, comprising two half-modules. The two half-modules cooperate to clamp the pipe and form a sealed chamber that connects to the damaged area. In actual use, when a damaged area appears on the pipe, the two half-modules are overlapped and sealed to block the damaged area. After the two half-modules overlap, they can be fixed for a long time by bolts or pins to prevent separation due to water pressure.

[0028] It should be noted that the semi-module has an arc-shaped structure, which is obtained by axially dividing a cylindrical structure. After the two semi-modules are covered together, they form a complete cylindrical structure, which can be used to seal the pipe and prevent water leakage.

[0029] The semi-module includes a semi-arc plate 100 and a sealing gasket 200 installed inside the semi-arc plate 100. In the installed state, the two semi-arc plates 100 cooperate to form a cylindrical structure surrounding the pipe. The two sealing gaskets 200 are deformed by the compression of the two semi-arc plates 100 to seal the gap between the cylindrical structure and the pipe, thereby forming a sealed chamber that connects to the damaged area. In other words, when the two semi-arc plates 100 are installed together to form a cylindrical structure, the sealing gaskets 200 installed in the two semi-arc plates 100 also cooperate to form a ring seal structure, which can completely seal the pipe in the circumferential direction.

[0030] Figure 3 A schematic diagram of the structure of the sealing gasket 200 is shown; Figure 3In this structure, the sealing gasket 200 includes a straight portion 210 and an arc-shaped portion 220. Two sets of straight portions 210 are arranged in parallel along the radial direction, and two sets of arc-shaped portions 220 are arranged in parallel along the axial direction. The two sets of arc-shaped portions 220 are connected between the two sets of straight portions 210. By setting the straight portions 210, the two axially parallel arc-shaped portions 220 can be connected to form a whole. The two parallel arc-shaped portions 220 have a gap in the axial direction. In actual use, the two arc-shaped portions 220 can form two ring seals. As long as the positions of the two arc-shaped portions 220 are kept on both sides of the seepage point, the seepage point can be sealed in two directions.

[0031] See also Figure 3 The arc-shaped portion 220 includes a double-groove pad 221 and a single-groove pad 222. The double-groove pad 221 and the single-groove pad 222 are spaced axially to form a temporary chamber that isolates the seepage point from the outside. The combination of the double-groove pad 221 and the single-groove pad 222 can form multiple seals, and the space between the double-groove pad 221 and the single-groove pad 222 can form a temporary chamber. This temporary chamber is positioned between the seepage point and the outside and can intercept leakage when the sealed chamber leaks, forming multiple layers of protection and further improving the sealing effect.

[0032] See also Figure 3 The inner side of the double-groove gasket 221 has radially upward-extending ribs. In the installed state, the ribs are deformed by compression and adhere to the outer surface of the pipe. The ribs will contact the pipe before the sealing surface of the double-groove gasket 221. As the two semi-arc plates 100 continue to approach each other, the ribs will be deformed by compression, so that the sealing surface and the outer surface of the pipe have a certain contact strength, ensuring the sealing effect of the sealing surface.

[0033] Figure 2 A schematic diagram of the semi-arc plate 100 is shown; Figure 2 In the process, the semi-circular plate 100 includes a sealing groove 110 for installing the sealing gasket 200. The sealing groove 110 includes a straight groove 111, an arc-shaped double groove 112, and an arc-shaped single groove 113. In the installed state, the straight part 210 is installed in the straight groove 111, the double groove gasket 221 is installed in the arc-shaped double groove 112, and the single groove gasket 222 is installed in the arc-shaped single groove 113. By installing the sealing gasket 200 through the pre-opened sealing groove 110, it can be ensured that the mating surface of the semi-circular plate 100 remains flat after the sealing gasket 200 is installed.

[0034] Both end faces of the semi-arc plate 100 are provided with extensions 120, and the inner side of the extensions 120 has radially extending anti-slip ribs 121. In the installed state, the anti-slip ribs 121 press against the outer wall of the pipe. The anti-slip ribs 121 are used to prevent the semi-arc plate 100 from moving axially relative to the pipe after it is fitted on the outside of the pipe, so as to ensure stable installation. It should be noted that the specific number and shape of the extensions 120 and the anti-slip ribs 121 are not limited.

[0035] In addition to strip-shaped edges, anti-slip ribs 121 can also be selected in other shapes, such as grid-shaped edges, Z-shaped edges, and other shapes. Continuous edges or segmented edges can be selected. The purpose is to increase the contact area between the repairer shell and the outer wall of the pipe when the repairer achieves a sealing effect, so as to increase the friction and thus play an anti-slip role.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
