Description

Technical Field

[0001] This invention relates to the field of trenchless repair technology for underground pipelines, specifically to a protective membrane traction device and method for trenchless repair of pipeline defects without interruption. Background Technology

[0002] As the years of use increase, underground drainage pipes are prone to varying degrees of damage, which can lead to sewage seepage that pollutes the surrounding environment, or external water (groundwater, river water, tap water leakage, etc.) seeping into and diluting the sewage in the pipes, resulting in problems such as increased sewage volume and low concentration. How to solve this pain point has become the focus of attention in the industry.

[0003] Chinese invention patent CN118391536B discloses a device for repairing pipe defects without damage while the pipe is wet (wet refers to no flow interruption). This device uses a capsule-type protective film to protect a thermosetting resin hose from deformation caused by sewage. The capsule-type protective film is fixed at both ends to a central flow pipe, with an overlap (or adhesive) in the middle. Under normal conditions, it adheres to the surface of the thermosetting resin hose for protection. When the ultraviolet heating lamp is activated and the sealing film inflates, the thermosetting resin hose gradually moves towards the inner wall of the pipe to be repaired. During this movement, the overlap of the capsule-type protective film is torn. However, in practice, the following shortcomings have been found: (1) When the capsule protective film is stretched due to the inflation of the sealing film, it is difficult to ensure that the capsule protective film is firmly connected to the outer wall of the central flow tube; the degree of overlap (or bonding) of the capsule protective film flaps is difficult to control. If the overlap is too strong, it will increase the difficulty of tearing. If the overlap is not strong, there is a risk of water leakage, which will affect the surface quality of the thermosetting resin hose. Therefore, the capsule protective film is more difficult to install, and the requirements for materials and construction personnel are higher, and the installation efficiency is lower. (2) The capsule-type protective film cannot be reused after it is torn, resulting in high cost and environmental pollution.

[0004] Therefore, it is necessary to provide a protective membrane traction device and method for trenchless repair of pipeline defects without interruption. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a protective membrane traction device and method for trenchless repair of pipeline defects without interruption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A protective membrane traction device for trenchless repair of pipeline defects without interruption includes a receiving component, a clamping component, traction ropes, pull ropes, a winding base, and a winding mechanism. The receiving component and the clamping component are both fixedly installed around the outer wall of a central flow pipe and are located at both ends of a thermosetting resin hose. One end of the protective membrane is fixedly connected to the receiving component, and the other end is bolted to several pull ropes inserted in the clamping component. The winding base is fixedly installed around the outer wall of the central flow pipe and is located outside the receiving component. The winding mechanism is fixedly installed on the winding base. Multiple traction ropes are arranged around the outer wall of the central flow pipe. The two ends of each traction rope are located on the inner and outer sides of the protective membrane, respectively. One end of each traction rope is fixedly connected to the inner receiving component, and the other end passes around the protective membrane and is connected to the winding shaft of the outer winding mechanism. Before repair, the other end of the protective film is pulled from the receiving assembly to the pressing assembly and fixed and sealed by several pull ropes. After the protective film covers the sealing film and the thermosetting resin hose, the pull ropes are removed. During repair, the pressing assembly releases the fixed seal on the protective film, and then the protective film is pulled into the receiving assembly for storage by the winding mechanism.

[0007] Preferably, the pressing assembly has a first cavity inside, and an inflatable rubber waterstop ring is installed in the first cavity; a membrane-penetrating groove is formed on the side of the pressing assembly near the thermosetting resin hose for the traction rope and the protective film to pass through, and a pull rope mounting hole is formed on the side of the pressing assembly away from the thermosetting resin hose for the pull rope to pass through; when the pull rope pulls the other end of the protective film into the first cavity, the inflatable rubber waterstop ring inflates and expands to fix and seal the other end of the protective film, and the pull rope is removed after inflation is completed.

[0008] Preferably, a winding groove is formed on the outer side of the winding base, which surrounds the central flow tube, and several threading tubes are installed in the winding groove; the winding shaft of the winding mechanism is rotatably installed in the winding groove and arranged along the axial direction of the central flow tube, and the other end of each traction rope passes through the threading tube and is fixedly connected to the winding shaft.

[0009] Preferably, a second cavity is formed inside the winding base; the winding mechanism also includes a winding motor, a first bevel gear, and a second bevel gear installed in the second cavity. The first bevel gear is fixedly installed on the output shaft of the winding motor, and the second bevel gear meshes perpendicularly with the first bevel gear. The winding shaft serves as the output shaft of the second bevel gear.

[0010] Preferably, the outer side of the receiving assembly has a receiving groove arranged around the central flow tube, with several lifting rings for binding the traction rope fixedly installed on one side, and the other side fixedly connected to the protective film, such as by adhesive.

[0011] Preferably, the traction ropes are evenly distributed around the central flow tube, the inlet of the conduit is matched with the position of the traction rope, and the outlet of the conduit extends to the take-up shaft and is evenly distributed along the axial direction of the take-up shaft to avoid mutual interference between the traction ropes.

[0012] Preferably, the winding motor is connected to the ground-based power distribution cabinet via a power distribution cable.

[0013] Preferably, the inflatable rubber waterstop ring is also equipped with an air inlet and outlet pipe; the compression assembly is provided with an air inlet and outlet pipe mounting hole for the air inlet and outlet pipe to pass through.

[0014] Preferably, the protective film is made of any one of the following materials: plastic, latex cloth, rubber cloth, or imitation leather cloth.

[0015] Furthermore, the present invention also provides a method for non-interruption, trenchless repair of pipeline defects using a protective membrane traction method, comprising the following steps: Before the central flow pipe section with the thermosetting resin hose installed enters the pipe to be repaired, several pull ropes are threaded through the clamping assembly. One end of each pull rope is tied to the other end of the protective membrane and then to the traction rope. The protective membrane is pulled from the other end of the pull ropes and moved into the clamping assembly for fixing and sealing. The pull ropes are then removed. After the central flow pipe enters the pipe to be repaired and discharges the water flow in the pipe section to be repaired, the fixing seal of the pressure assembly on the other end of the protective membrane is released, and then the winding mechanism pulls several traction ropes to wind up the membrane. At the same time, several traction ropes pull the protective membrane into the receiving assembly.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: (1) The protective film is recyclable, can be used multiple times, has low cost, and is low-carbon and environmentally friendly; (2) The protective film does not need to have the elasticity of rubber, but only needs to meet the simple requirements of flexibility and waterproofing, which reduces the difficulty of material selection and manufacturing; (3) The design of the inflatable rubber waterstop ring and the first cavity of the annular seal can quickly achieve the fixation of the protective membrane pressure end and water stop sealing, which is very convenient for construction.

[0021] Example 1

[0022] Please see Figure 1-8 This embodiment provides a protective membrane traction device for trenchless repair of pipeline defects without interruption, including a receiving assembly 12, a pressing assembly 9, a traction rope 5, a pull rope 11, a winding base 13, and a winding mechanism 14; the receiving assembly 12 and the pressing assembly 9 are both fixedly installed around the outer wall of the central flow pipe 1 and are located at both ends of the thermosetting resin hose 2; one end of the protective membrane 4 is fixedly connected to the receiving assembly 12, and the other end is bolted to several pull ropes 11 inserted in the pressing assembly 9; the winding base 13 is fixedly installed around the outer wall of the central flow pipe 1 and is located outside the receiving assembly 12, and the winding mechanism 14 is fixedly installed on the winding base 13; multiple traction ropes 5 are arranged around the outer wall of the central flow pipe 1, and the two ends of each traction rope 5 are located on the inner and outer sides of the protective membrane 4, one end of which is fixedly connected to the inner receiving assembly 12, and the other end passes around the protective membrane 4 and is connected to the winding shaft 14d of the outer winding mechanism 14; Before repair, the other end of the protective film 4 is pulled from the receiving assembly 12 to the pressing assembly 9 by several pull ropes 11 and fixed and sealed. After the protective film 4 covers the sealing film and the thermosetting resin hose 2, the pull ropes 11 are removed. During repair, the pressing assembly 9 releases the fixed seal on the protective film 4, and then the winding mechanism 14 pulls the protective film 4 into the receiving assembly 12 for storage, so that the protective film 4 is removed from the cover.

[0023] It should be noted that the sealing membrane is a component disclosed in Chinese invention patent CN118391536B. It is fixedly installed around the outer wall of the central flow pipe 1 at both ends, and contains an ultraviolet heating lamp assembly 3 inside. A thermosetting resin hose 2 is adhered to its outer surface. When the sealing membrane is inflated, the thermosetting resin hose 2 expands to fit against the inner wall of the pipe to be repaired. The sealing membrane can be formed by bonding the inner membrane of the thermosetting resin hose 2 with geomembranes at both ends, or it can be manufactured as a single piece.

[0024] Specifically, the pressure-fixing component 9 has a first cavity 9f inside, and an inflatable rubber waterstop ring 10 is installed in the first cavity 9f. A membrane-penetrating groove 9c is formed on the side of the pressure-fixing component 9 closest to the thermosetting resin hose 2 for the traction rope 5 and the protective membrane 4 to pass through. A pull rope mounting hole 9e is formed on the side of the pressure-fixing component 9 furthest from the thermosetting resin hose 2 for the pull rope 11 to pass through. When the pull rope 11 pulls the other end of the protective membrane 4 into the first cavity 9f, the inflatable rubber waterstop ring 10 inflates and expands to fix and seal the other end of the protective membrane 4. After inflation is complete, the pull rope 11 is removed. The traction rope 5 can be made of hemp rope, polyester imitation hemp rope, Manila hemp rope, etc., and the pull rope 11 can also be made of hemp rope, polyester imitation hemp rope, Manila hemp rope, etc. The traction ropes 5 are evenly arranged around the central flow pipe 2, and the number of traction ropes 5 increases with the increase of the diameter of the central flow pipe 2. The number of pull ropes 11 matches the number of traction ropes 5. The expansion volume of the inflatable rubber waterstop ring 10 is greater than the volume of the first cavity 9f.

[0025] More specifically, the compression assembly 9 includes a first ring plate 9a and a second ring plate 9b; the first ring plate 9a has a generally rectangular cross-section and is positioned close to the thermosetting resin hose 2, with a groove formed on the side facing away from the thermosetting resin hose 2; the second ring plate 9b has a generally L-shaped cross-section and is positioned away from the thermosetting resin hose 2. After the first ring plate 9a and the second ring plate 9b are closely welded to the outer wall of the central flow pipe 1, the extended section of the second ring plate 9b overlaps the outermost side of the first ring plate 9a, and the gap formed between them serves as a membrane penetration groove 9c; the outermost vertical section of the second ring plate 9b... A groove is also formed on the side, and the two grooves are matched and joined together to form a first cavity 9f, which is used to accommodate the inflatable rubber waterstop ring 10; multiple holes are formed on the side of the second ring plate 9b away from the thermosetting resin hose 2, which serve as pull rope mounting holes 9e. The position of the pull rope mounting holes 9e corresponds to the axial arrangement position of the traction rope 5 and the pull rope 11; in addition, the inflatable rubber waterstop ring 10 is also equipped with an air inlet and outlet pipe 10a. An air inlet and outlet pipe mounting hole 9d is formed on the side of the second ring plate 9b away from the thermosetting resin hose 2 for installing the air inlet and outlet pipe 10a.

[0026] Preferably, the intake and exhaust pipe 10a is a three-way pipe, one end of which is connected to the inflatable rubber waterstop ring 10, and the other end is equipped with a one-way air intake valve as an inflation valve. The other end is equipped with a solenoid valve as an exhaust valve. The solenoid valve is connected to the ground control switch via a power cable. When installing the protective membrane, before pulling the protective membrane 4 and the traction rope 5 into the first cavity 9f by the pull rope 11, the solenoid valve is opened first to release the gas in the inflatable rubber waterstop ring 10, leaving installation space for the protective membrane 4 and the traction rope 5. Then the solenoid valve is closed, and the protective membrane... After 4 and the traction rope 5 are in place, connect the one-way air inlet valve to the air compressor to inflate the inflatable rubber waterstop ring 10, so that the inflatable rubber waterstop ring 10 expands to fill the first cavity 9f and presses against the protective membrane 4 and the traction rope 5 to achieve a fixed seal on the protective membrane 4; when the sewage between the two annular blocking airbags is drained to form a repair space, the control solenoid valve is opened, the inflatable rubber waterstop ring 10 is deflated, the winding mechanism winds up the traction rope 5, the protective membrane 4 is contained, and the sealing membrane expands smoothly until the thermosetting resin hose 2 is tightly attached to the inner wall of the pipe to be repaired.

[0027] Specifically, a winding groove 13e is formed on the outer side of the winding base 13, which surrounds the central flow tube 1. Several threading tubes 13f are installed in the winding groove 13e. The winding shaft 14d of the winding mechanism 14 is rotatably installed in the winding groove 13e and arranged along the axial direction of the central flow tube 1. The other end of each traction rope 5 passes through the threading tube 13f and is fixedly connected to the winding shaft 14d.

[0028] Specifically, the winding base 13 has a second cavity 13g inside; the winding mechanism 14 also includes a winding motor 14a, a first bevel gear 14b, and a second bevel gear 14c installed in the second cavity 13g. The first bevel gear 14b is fixedly mounted on the output shaft of the winding motor 14a, and the second bevel gear 14c meshes perpendicularly with the first bevel gear 14b. The winding shaft 14d serves as the output shaft of the second bevel gear 14c. The winding motor 14a is connected to the ground-level power distribution cabinet via a power cable 6. The winding motor 14a can be a waterproof micro motor.

[0029] Specifically, the traction rope 5 is evenly arranged around the central flow tube 1, the inlet of the threading tube 13f is matched with the position of the traction rope 5, and the outlet of the threading tube 13f extends to near the take-up shaft 14d and is evenly arranged along the axial direction of the take-up shaft 14d to avoid mutual interference of the traction ropes 5.

[0030] More specifically, the winding base 13 includes a base body 13a. The base body 13a originally has a rectangular cross-section and a thick ring plate structure. However, an irregularly shaped cavity is opened at a certain position inside it to serve as a second cavity 13g for accommodating the winding motor 14a, the first bevel gear 14b, and the second bevel gear 14c. The second cavity 13g is usually located at the top of the central flow pipe 1 and is knife-shaped. The second cavity 13g is sealed on the outside of the base body 13a by the base sealing member 13b to prevent water from the pipe to be repaired from entering the second cavity 13g. A groove with a small rectangular cross-section and arranged in a ring around the central flow pipe is removed from the original rectangular outer ring of the base body 13a to serve as a winding groove 13e. The two sides of the winding groove 13e are respectively the first positioning... Plate 13c, second positioning plate 13d; a take-up shaft 14d is rotatably installed in the take-up groove 13e at a position matching the second cavity 13g. Both ends of the take-up shaft 14d are connected to the first positioning plate 13c and the second positioning plate 13d through bearings. The take-up shaft 14d is preferably located at the top of the central flow tube 1. The output torque of the take-up motor 14a is transmitted to the take-up shaft 14d in sequence through the first bevel gear 14b and the second bevel gear 14c. Different traction ropes 5 are wound in the same direction on the take-up shaft 14d. When the take-up shaft 14d rotates, it can control all traction ropes 5 to wind synchronously. The first positioning plate 13c is provided with multiple threading holes around the central flow tube 1. The position of the threading holes matches the position of the traction ropes 5, and the threading holes serve as the inlet of the threading tube 13f.

[0031] Specifically, the receiving component 12 has a ring-shaped structure and the cross-section of the receiving component 12 is generally groove-shaped. A receiving groove 12a is formed on the outside, which surrounds the central flow pipe 1. Several lifting rings 12b for binding the traction rope 5 are fixedly installed on the side of the receiving component 12 close to the thermosetting resin hose. The other side of the receiving component 12 (away from the thermosetting resin hose) is fixedly connected to the protective film 4, such as by bonding.

[0032] Specifically, the protective film 4 is made of any one of the following materials: plastic, latex cloth, rubber cloth, or imitation leather cloth, such as rubber cloth.

[0033] Specifically, in this embodiment, the central flow pipe 1 is assembled from multiple prefabricated pipe sections. The central flow pipe 1, which is equipped with thermosetting resin hose 2, is actually a single pipe section and is the core pipe section of the repair device. From the pipe wall outwards, the pipe section is arranged with the following components: UV heating lamp group 3, sealing film + thermosetting resin hose 2, and protective film 4. The sealing film is fixed at both ends by fixing seats 8. The fixing seats 8 can be made of two thin plates welded to the outer wall of the pipe section, which are bonded to the sealing film to ensure a strong bond and sufficient air pressure resistance. A flange 1a is installed at the end of the pipe section for easy connection to adjacent pipe sections. The housing assembly 12 can share some of the material with the fixing seat 8.

[0034] Example 2

[0035] Please see Figure 1-8 This embodiment provides a traction method for trenchless repair of pipeline defects without interruption, employing the trenchless repair traction device for pipeline defects without interruption as described in Embodiment 1, and includes the following steps: Before the central flow pipe 1 section with thermosetting resin hose 2 enters the pipe to be repaired, several pull ropes 11 are threaded through the pressure assembly 9. One end of the pull ropes 11 is connected to the other end of the protective film 4 and to the traction rope 5. The protective film 4 is pulled from the other end of the pull ropes 11 and moved into the pressure assembly 9 for fixing and sealing. The pull ropes 11 are then removed. After the central flow pipe 1 enters the pipe to be repaired and discharges the water flow in the pipe section to be repaired, the fixing seal of the pressure assembly 9 on the other end of the protective membrane 4 is released, and then the winding mechanism 14 pulls several traction ropes 5 to wind up the protective membrane 4 into the receiving assembly 12.

[0036] Specifically, while the pull rope 11 pulls the protective film 4, it also pulls the traction rope 5 to move towards the pressing component 9. At this time, the winding motor 14a needs to release the control of the winding shaft 14d so that the winding shaft 14d can rotate freely in the opposite direction to release a sufficient length of traction rope 5.

[0037] Specifically, the solenoid valve installed on the intake and exhaust pipe 10a is closed, allowing the gas inside the inflatable rubber water seal ring 10 to be discharged, and the pressure fixing component 9 automatically releases the fixed seal on the other end of the protective film 4.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
