Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a pipeline repair device. Background Technology

[0002] Urban underground drainage pipe network systems are an important part of urban infrastructure, mainly used to collect, transport, and discharge rainwater, domestic sewage, and industrial wastewater within the city, ensuring the normal operation of the city and the living environment of residents. However, underground drainage pipe network systems are inevitably affected by many complex factors such as pipe materials, interface types, laying environment, and water quality, and leakage problems are inevitable. To solve leakage problems, municipal departments often conduct regular inspections of underground drainage pipe network systems. After inspection and cleaning, repair robots are usually used to repair the pipes.

[0003] However, existing repair robots can only use air pressure to press the pipe liner against the inner wall of the pipe, and cannot further enhance the fit between the pipe liner and the pipe. Utility Model Content

[0004] The main purpose of this invention is to propose a pipe repair device, which aims to improve the problem that existing repair robots can only squeeze the pipe liner onto the inner wall of the pipe through air pressure, and cannot further enhance the fit between the pipe liner and the pipe.

[0005] To achieve the above objectives, the pipeline repair device proposed in this utility model includes:

[0006] The pipe liner is cylindrical and extends along a first direction to fit the inner wall of the pipe.

[0007] A rotating structure is provided in the inner lining of the pipe, including a mounting ring and a plurality of first rolling parts. The plurality of first rolling parts are arranged circumferentially at intervals on the outer ring surface of the mounting ring, and each first rolling part is capable of rolling at least in a first direction.

[0008] A clamping structure, arranged in a ring and sleeved around the periphery of a plurality of the first rolling portions, is elastically configured to press against the inner wall surface of the pipe liner; and,

[0009] A curing structure is provided, connected to the mounting ring, and the curing structure is used to emit ultraviolet light to the pipe lining to cure the pipe lining to the inner wall surface of the pipe.

[0010] In one embodiment, the outer ring surface of the mounting ring is provided with a plurality of recesses spaced apart along its circumference;

[0011] Each of the first rolling portions includes a ball, which is rotatably disposed within the corresponding groove.

[0012] In one embodiment, the groove has a depth of A, an opening diameter of B, and a ball radius of C, where C < A < 2C and B < 2C.

[0013] In one embodiment, the mounting ring includes a plurality of ring segments spaced apart circumferentially, each ring segment being movably disposed in the curing structure in the radial direction of the mounting ring, and each ring segment having a portion of the first rolling portion;

[0014] The clamping structure is sleeved on the circumferential side of the plurality of ring segments.

[0015] In one embodiment, the curing structure is provided with a plurality of telescopic rods, which are spaced apart circumferentially and extend radially along the mounting ring so as to be able to extend or retract radially in the mounting ring. The driving end of each telescopic rod is connected to the corresponding ring segment so as to drive the corresponding ring segment to move radially in the mounting ring.

[0016] In one embodiment, the pipe repair device further includes two limiting structures, which are respectively disposed on both sides of the mounting ring in the first direction, and the two limiting structures are respectively disposed abutting against the two ends of the clamping structure in the first direction.

[0017] In one embodiment, each of the limiting structures includes:

[0018] A limiting ring is provided at a distance from the mounting ring in a first direction; and...

[0019] Multiple second rolling portions are circumferentially spaced on one end face of the limiting ring facing the mounting ring, and protrude radially from the mounting ring to abut against one side end of the clamping structure in the first direction.

[0020] In one embodiment, the clamping structure includes a clamping airbag, which is sleeved around the periphery of a plurality of the first rolling portions and is used to press against the inner wall surface of the pipe liner when inflated; or,

[0021] The clamping structure includes an elastic rubber ring, which is sleeved on the periphery of a plurality of first rolling portions, and is used to press against the inner wall surface of the pipe liner.

[0022] In one embodiment, the pipe lining is made of glass fiber, which is impregnated with a light-curing resin.

[0023] In one embodiment, the pipe repair device further includes a traveling structure disposed on the curing structure, the traveling structure being used to drive the curing structure to move within the pipe along a first direction.

[0024] In the technical solution of this utility model, after the pipeline inspection and cleaning work is completed, pipeline repair work is required. At this time, the user first places the pipeline liner inside the pipeline and seals both ends of the pipeline liner in the first direction. Then, air is blown into the pipeline liner to increase the air pressure inside the pipeline liner. Under the action of the air pressure difference, the pipeline liner is forced to deform and adhere to the inner wall surface of the pipeline, achieving a pre-fit between the pipeline liner and the pipeline. Since the rotating structure, the pressing structure, and the curing structure are all located within the pipeline liner, the pressing structure can press against the inner wall surface of the pipeline liner, further pressing the pipeline liner against the inner wall surface of the pipeline to improve the fit strength between the pipeline liner and the pipeline. At this time, the curing structure drives the rotating structure to move together in the pipeline along the first direction. The process involves emitting ultraviolet light onto the pipe lining. During operation, the clamping structure remains pressed against the pipe lining, resulting in significant friction between them. This friction causes the clamping structure to tend to rotate from the inside out. Since the clamping structure is fitted around the periphery of the multiple first rolling parts, and these first rolling parts can roll at least along a first direction, they can also roll along the first direction as the clamping structure rotates. This reduces resistance to the rotation of the clamping structure and ensures that the clamping structure remains fitted around the periphery of the multiple first rolling parts, maintaining the stability of the relative position between the rotating structure and the clamping structure. Simultaneously, the curing process emits ultraviolet light onto the pipe lining, curing the portion of the pipe lining that has been clamped by the clamping structure, thus repairing the pipe. With this configuration, when the curing structure and the rotating structure drive the clamping structure to move along the first direction inside the pipe, the cooperation between the rotating structure and the clamping structure can convert the sliding friction between the clamping structure and the pipe lining into rolling friction. This protects the pipe lining and prevents damage to it, thus ensuring the quality of pipe repair work, while the clamping structure increases the fit strength between the pipe lining and the pipe. At the same time, the rotating structure ensures the stability of the relative position between the clamping structure and the rotating structure. The rotating structure, the clamping structure, and the curing structure are compact in size, lightweight, and easy to store and carry. Attached Figure Description

[0034] This invention proposes a pipe repair device. It aims to address the problem that existing repair robots can only press the pipe liner against the inner wall of the pipe using air pressure, failing to further enhance the fit between the pipe liner and the pipe.

[0035] Please see Figure 1-2 In one embodiment of this utility model, the pipe repair device 100 includes a pipe liner 1, a rotating structure 2, a pressing structure 3, and a curing structure 4. The pipe liner 1 is cylindrical and extends along a first direction to fit the inner wall of the pipe. The rotating structure 2 is disposed in the pipe liner 1 and includes an mounting ring 21 and a plurality of first rolling parts 22. The plurality of first rolling parts 22 are circumferentially spaced on the outer ring surface of the mounting ring 21, and each first rolling part 22 can roll at least along the first direction. The pressing structure 3 is annular and is sleeved on the periphery of the plurality of first rolling parts 22. The pressing structure 3 is elastic and is used to press against the inner wall of the pipe liner 1. The curing structure 4 is connected to the mounting ring 21 and is used to emit ultraviolet light to the pipe liner 1 to cure the pipe liner 1 onto the inner wall of the pipe.

[0036] In the technical solution of this utility model, after the pipeline inspection and cleaning work is completed, the pipeline needs to be repaired. At this time, the user first places the pipeline liner 1 inside the pipeline and seals both ends of the pipeline liner 1 in the first direction. Then, air is blown into the pipeline liner 1 to increase the air pressure inside the pipeline liner 1. Under the action of air pressure difference, the pipeline liner 1 is forced to deform and make the pipeline liner 1 fit against the inner wall surface of the pipeline, realizing the pre-fitting of the pipeline liner 1 and the pipeline. At this time, since the rotating structure 2, the pressing structure 3 and the curing structure 4 are all provided in the pipeline liner 1, the pressing structure 3 can press against the inner wall surface of the pipeline liner 1 and further press the pipeline liner 1 against the inner wall surface of the pipeline to improve the fit strength between the pipeline liner 1 and the pipeline. At this time, the curing structure 4 drives the rotating structure 2 to move together in the pipeline in the first direction and pushes towards the inner wall surface of the pipeline. The pipe liner 1 emits ultraviolet light. During the operation, since the clamping structure 3 is always pressed against the pipe liner 1, there is a large friction between the clamping structure 3 and the pipe liner 1. Under the action of friction, the clamping structure 3 tends to flip from the inside to the outside. At the same time, since the clamping structure 3 is sleeved on the periphery of the plurality of first rolling parts 22, and the plurality of first rolling parts 22 can roll at least in the first direction, the plurality of first rolling parts 22 can roll in the first direction as the clamping structure 3 flips, thereby reducing the obstruction to the flipping of the clamping structure 3 and ensuring that the clamping structure 3 is always sleeved on the periphery of the plurality of first rolling parts 22 to ensure the stability of the relative position between the rotating structure 2 and the clamping structure 3. Meanwhile, the curing process emits ultraviolet light to the pipe liner 1, which can cure the part of the pipe liner 1 that has been clamped by the clamping structure 3, thereby achieving the repair of the pipe. With this configuration, when the curing structure 4 and the rotating structure 2 drive the pressing structure 3 to move along the first direction inside the pipe, the cooperation between the rotating structure 2 and the pressing structure 3 can convert the sliding friction between the pressing structure 3 and the pipe liner 1 into rolling friction. This protects the pipe liner 1 from damage while the pressing structure 3 increases the fit strength between the pipe liner 1 and the pipe, thus preventing damage to the pipe liner 1 and affecting the quality of pipe repair work. At the same time, the rotating structure 2 ensures the stability of the relative position between the pressing structure 3 and the rotating structure 2. The rotating structure 2, the pressing structure 3, and the curing structure 4 are small in size, lightweight, and easy to store and carry.

[0037] It is understandable that, since the clamping structure 3 is elastically configured, and when the clamping structure 3 is sleeved on the periphery of the plurality of first rolling parts 22, the clamping structure 3 is always in a stretched state. Therefore, when the clamping structure 3 flips from the inside to the outside, the outer ring surface of the clamping structure 3 flips to its inner ring surface, and this part contracts, reducing the elastic deformation. The inner ring surface of the clamping structure 3 flips to its outer ring surface, and this part stretches, increasing the elastic deformation. In this way, it is ensured that no matter how the clamping structure 3 flips, it can always be stably sleeved on the periphery of the plurality of first rolling parts 22, so as to achieve a stable fit between the clamping structure 3 and the rotating structure 2.

[0038] It should be noted that, to ensure the pipe lining 1 can cure under ultraviolet light and adhere to the inner wall of the pipe, in one embodiment of this invention, the pipe lining 1 is made of glass fiber impregnated with a light-curing resin. This configuration provides the glass fiber with a certain degree of sealing and structural integrity. When the glass fiber is exposed to ultraviolet light, the light-curing resin impregnated on the glass fiber cures, changing from a liquid to a solid state. The cured resin then restricts the deformation of the glass fiber, thereby curing the pipe lining 1 and enabling pipe repair.

[0039] It should be further explained that, in order to enable the curing structure 4 to drive the rotating structure 2 and the pressing structure 3 to move along the first direction within the pipe, in a further embodiment of this utility model, the pipe repair device 100 further includes a traveling structure 6. The traveling structure 6 is disposed on the curing structure 4 and is used to drive the curing structure 4 to move along the first direction within the pipe. With this configuration, when the curing structure 4 needs to drive the rotating structure 2 and the pressing structure to move along the first direction, the traveling structure 6 operates to drive the curing structure 4 to move along the first direction, and to drive the rotating structure 2 and the pressing structure 3 to move together in the first direction.

[0040] Of course, this utility model does not limit the specific structural form of the walking structure 6. In one embodiment of this utility model, the walking structure 6 includes multiple walking wheels, which are respectively rotatably disposed on opposite sides of the curing structure 4 and can all be rolled along the first direction. Thus, when the curing structure 4 needs to move along the first direction, the multiple walking wheels rotate synchronously to drive the curing structure 4 to move along the first direction, thereby driving the rotating structure 2 and the pressing structure 3 to move.

[0041] In another embodiment of this utility model, the walking structure 6 can also be configured as two tracks, which are respectively located on opposite sides of the solidified structure 4 and can both travel along the first direction. With this configuration, the solidified structure 4 can also move along the first direction.

[0042] Similarly, this utility model does not limit the driving form of the walking structure 6. For example, in one embodiment of this utility model, the pipe repair device 100 further includes a power supply and a drive motor. The power supply is electrically connected to the drive motor, and the drive motor is driven by the walking structure 6. When the walking structure 6 needs to move, the power supply supplies energy to the drive motor, and the drive motor drives the walking structure 6 to move, thereby driving the curing structure 4 to drive the rotating structure 2 and the pressing structure 3 to move together in the first direction.

[0043] In another embodiment of this utility model, the pipeline repair device 100 further includes an oil tank and an engine. The oil tank contains fuel and is connected to the engine. The engine is driven by the walking structure 6. When the walking structure 6 needs to move, the fuel in the oil tank flows into the engine for combustion. The engine performs work to drive the walking structure 6 to move, thereby driving the solidification structure 4 to move together with the rotating structure 2 and the pressing structure 3 in the first direction.

[0044] Furthermore, this utility model does not limit the specific structural form of the rolling part. In one embodiment of this utility model, the outer ring surface of the mounting ring 21 is provided with a plurality of grooves spaced apart along its circumference, and each of the first rolling parts 22 includes a ball bearing, which is rotatably disposed in the corresponding groove. With this arrangement, the groove is used to accommodate the ball bearing. At the same time, since the ball bearing is rotatably disposed in the corresponding groove, when the pressing structure 3 flips from the inside to the outside, the ball bearing rotates in the first direction, thereby achieving synchronous rotation with the pressing structure 3. This ensures the stability of the relative position of the rotating structure 2 and the pressing structure 3 when the pressing structure 3 rolls on the pipe liner 1, and avoids misalignment between the two.

[0045] It is understood that in this embodiment, each ball is configured to rotate independently.

[0046] It should be noted that during the clamping operation, the clamping structure 3 repeatedly rotates. Because it is elastically designed, prolonged clamping may lead to differences in elastic deformation at various points on the inner ring surface of the clamping structure 3. Over time, this can easily affect the service life of the clamping structure 3. By designating the first rolling part 22 as a ball bearing, not only can the relative position of the rotating structure 2 and the clamping structure 3 be stabilized, but the difference in elastic deformation at various points on the inner ring surface of the clamping structure 3 can also be mitigated. Since each ball bearing rotates independently, when the elastic deformation of the inner ring surfaces on both sides of the ball bearing is unequal, the external force on the ball bearing will also differ. At this time, under the action of the external force, the rotation direction of the ball bearing will shift, causing the side with larger elastic deformation to contract and the side with smaller elastic deformation to stretch, thus stabilizing the external force applied to the ball bearing on both sides. At this point, the elastic deformation on both sides will also tend to be equal, thereby achieving the purpose of mitigating the difference in elastic deformation at various points on the inner ring surface of the clamping structure 3.

[0047] In another embodiment of this utility model, each of the first rolling parts 22 includes a roller, which is rotatably mounted on the mounting ring 21 and is capable of rolling along a first direction. With this configuration, when the clamping structure 3 flips from the inside out, the roller can also roll along the first direction, thereby achieving synchronous rotation with the clamping structure 3. This ensures the stability of the relative positions of the rotating structure 2 and the clamping structure 3 when the clamping structure 3 rolls on the pipe liner 1, preventing misalignment between them.

[0048] In other embodiments of this utility model, the first rolling part 22 can also be configured in other structural forms, which can be selected according to the actual requirements.

[0049] Specifically, in this embodiment, the outer ring surface of the mounting ring 21 is provided with a plurality of grooves spaced apart along its circumference, and each of the first rolling parts 22 includes a ball, which is rotatably disposed in the corresponding groove.

[0050] To ensure the stability of the ball bearing within the corresponding groove and prevent it from falling out, which could destabilize the relative positions of the rotating structure 2 and the clamping structure 3, in a further embodiment of this invention, the groove depth is A, the groove opening diameter is B, and the ball bearing radius is C, where C < A < 2C and B < 2C. With this configuration, since the groove depth is greater than the ball bearing radius but less than the ball bearing diameter, the center of the ball bearing is located within the groove, and at least a portion of the ball bearing is always visible within the groove. Simultaneously, because the groove opening diameter is smaller than the ball bearing diameter, the ball bearing cannot detach from the groove opening. This ensures both the ball bearing and the clamping structure 3 are in contact, thus guaranteeing the stability of the ball bearing's installation.

[0051] It should be noted that the pipe liner 1 deforms by inflation to fit the inner wall of the pipe, thus enabling the pipe liner 1 to adapt to pipes of various sizes. In order to enable the rotating structure 2 and the pressing structure 3 to also adapt to pipes of various sizes, in one embodiment of this utility model, the mounting ring 21 includes a plurality of ring segments 211 arranged circumferentially. Each ring segment 211 is movably disposed on the curing structure 4 in the radial direction of the mounting ring 21. Each ring segment 211 is provided with a portion of the first rolling part 22. The pressing structure 3 is sleeved on the circumferential side of the plurality of ring segments 211. With this configuration, when the clamping operation needs to begin, multiple ring segments 211 move together to move away from the mounting ring 21 radially, thereby increasing the distance between two relative ring segments 211 and thus increasing the radius of the mounting ring 21, until the clamping structure 3 clamps the pipe liner 1. At this time, the clamping structure 3 is continuously stretched, and its elastic deformation increases, so that it can continue to be fitted on the outside of multiple first rolling parts 22, thereby realizing the adaptation of the rotating structure 2 and the clamping structure 3 to pipes of various sizes.

[0052] Of course, this utility model does not limit the specific movement form of the multiple ring segments 211. In one embodiment of this utility model, the solidification structure 4 is provided with multiple telescopic rods 41. The multiple telescopic rods 41 are arranged at circumferential intervals and extend radially along the mounting ring 21 so as to be able to extend or retract radially in the mounting ring 21. The driving end of each telescopic rod 41 is connected to the corresponding ring segment 211 so as to drive the corresponding ring segment 211 to move radially in the mounting ring 21. With this arrangement, when the multiple ring segments 211 need to move radially away from the mounting ring 21, the multiple telescopic rods 41 extend to drive the corresponding ring segment 211 to move, thereby increasing the radius of the mounting ring 21, so that the rotating structure 2 and the clamping structure 3 can adapt to pipes of various sizes.

[0053] In another embodiment of this utility model, the curing structure 4 has a plurality of sliding grooves spaced axially at one end face near the rotating structure 2 in a first direction. These sliding grooves extend radially along the mounting ring 21, and the distance between two adjacent mounting rings 21 is mutually offset in a direction away from the center of the mounting ring 21. Each ring segment 211 has a slider at one end near the curing structure 4, and the slider slides in cooperation with the corresponding sliding groove. With this configuration, when the ring segments 211 need to move radially away from the mounting ring 21, the sliders slide in a direction away from the center of the mounting ring 21, thereby moving the corresponding ring segment 211. This also increases the radius of the mounting ring 21, allowing the rotating structure 2 and the clamping structure 3 to adapt to pipes of various sizes.

[0054] In other embodiments of this utility model, the radius of the mounting ring 21 can also be adjusted in other ways. In actual settings, the appropriate method can be selected according to the requirements. This utility model does not impose any restrictions on this.

[0055] Furthermore, to further ensure the stability of the relative position between the clamping structure 3 and the rotating structure 2, in one embodiment of this utility model, the pipe repair device 100 further includes two limiting structures 5, respectively disposed on both sides of the mounting ring 21 in the first direction. The two limiting structures 5 are respectively disposed abutting against the two ends of the clamping structure 3 in the first direction. With this arrangement, when the clamping structure 3 is flipped, the two limiting structures 5 can jointly restrict the displacement movement of the clamping structure 3 relative to the rotating structure 2 in the first direction, thereby ensuring the stability of the relative position between the clamping structure 3 and the rotating structure 2.

[0056] Of course, this utility model does not limit the specific structural form of the limiting structure 5. In one embodiment of this utility model, each limiting structure 5 includes a limiting plate, which is disposed against one side end of the pressing structure 3 in the first direction. This arrangement can limit the positional movement of the pressing structure 3 relative to the rotating structure 2.

[0057] In another embodiment of this utility model, each of the limiting structures 5 includes a limiting ring 51 and a plurality of second rolling parts 52. The limiting ring 51 is spaced apart from the mounting ring 21 in a first direction. The plurality of second rolling parts 52 are circumferentially spaced at one end face of the limiting ring 51 facing the mounting ring 21 and protrude radially from the mounting ring 21 to abut against one side end of the pressing structure 3 in the first direction. With this configuration, when the pressing structure 3 is flipped, the limiting ring 51 can restrict the limiting structure 5 from rotating relative to the rotating structure 2 in the first direction. At this time, since the plurality of second rolling parts 52 abut against the pressing structure 3, the plurality of second rolling parts 52 can roll along the first direction as the pressing structure 3 is flipped. In this way, the sliding friction between the plurality of second rolling parts 52 and the pressing structure 3 can be converted into rolling friction, which not only reduces the obstruction to the flipping of the pressing structure 3, but also further protects the pressing structure 3 and extends the service life of the pressing structure 3.

[0058] In other embodiments of this utility model, the limiting structure 5 can also be set to other structural forms. In actual setting, it can be selected according to the needs, and this utility model does not limit it.

[0059] This utility model does not limit the specific structural form of the pressing structure 3. In one embodiment of this utility model, the pressing structure 3 includes a pressing airbag. The pressing airbag is sleeved on the periphery of a plurality of first rolling parts 22 and is used to press against the inner wall surface of the pipe liner 1 when inflated. With this arrangement, the pressing force of the pressing airbag on the pipe liner 1 can be adjusted by adjusting the inflation amount of the pressing airbag, and the start and stop time of the pressing operation can be determined.

[0060] In another embodiment of this utility model, the clamping structure 3 includes an elastic rubber ring, which is sleeved around the periphery of the plurality of first rolling portions 22, and the elastic rubber ring is used to press against the inner wall surface of the pipe liner 1. This arrangement can ensure the service life of the clamping structure 3.

[0061] In other embodiments of this utility model, the clamping structure 3 can also be configured as other structural forms, which can be selected according to the actual requirements.

[0062] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
