Description

Technical Field

[0001] This utility model relates to the field of CIPP pipeline thermosetting repair technology, specifically to a CIPP pipeline thermosetting repair device. Background Technology

[0002] In the field of CIPP pipe thermosetting repair, existing repair devices are mostly fixed-length integrated structures, with the core consisting of a single support frame, a manual opening mechanism, and an independent curing component. During use, operators must first select the appropriate integrated device based on the length of the pipe to be repaired. After placing the entire device into the inner pipe for repair, they manually rotate the screw or lever to push the opening component against the inner wall of the inner pipe to complete the opening. Then, the independent thermosetting equipment is activated, connected to the inner pipe via a cable, to heat and cure the opened inner pipe. During this process, the curing equipment needs to be manually moved to cover the entire repair area, completing the pipe repair operation.

[0003] However, existing technologies have significant shortcomings, making it difficult to meet the needs for efficient and flexible repair. First, they lack length adaptability. Fixed-length integrated devices cannot be flexibly adjusted according to pipe length. If the length of the pipe to be repaired does not match the device specifications, the entire device must be replaced, increasing equipment procurement costs and delaying the repair schedule. Furthermore, for inner pipes of different diameters, additional support components of corresponding sizes are required, further increasing operational complexity and cost. Second, the support operation is cumbersome and lacks sufficient protection. Manual support mechanisms rely on manual force, which can easily lead to uneven force causing localized deformation or damage to the inner pipe. Additionally, the high friction between the support components and the inner pipe can easily scratch the inner pipe surface when moving the device to adjust its position, affecting subsequent curing effects. Finally, curing efficiency is low and uniformity is poor. Independent curing equipment requires manual movement to cover the repair area, which can easily lead to localized irradiation or insufficient heating, resulting in uneven curing of the inner pipe and affecting the sealing and structural strength of the repaired pipe. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a CIPP pipe thermosetting repair device. In this utility model, the number of installation plates can be adjusted by connecting components according to the size of the pipe to be repaired and the inner pipe. The connecting rod is inserted into the connecting cylinder of the adjacent installation plate, and the fastener is rotated to lock it. This allows the length of the device to be adapted to the repair needs without replacing the entire set of equipment. It is suitable for various pipe specifications and reduces costs.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a CIPP pipe thermosetting repair device, including an installation plate and connectors, the connectors being symmetrically arranged and fixed to the side of the installation plate, and also including a spreading component, a connecting component and a curing component. The spreading component is used to spread open the inner pipe for repair, the connecting component is used to connect several installation plates according to the length of the inner pipe for repair, and the curing component is used to cure the inner pipe for repair.

[0006] More preferably, the spreading assembly includes a rotating disk, a worm gear assembly, sliding members, and rollers. The rotating disk is rotatably connected to the mounting disk, the worm gear in the worm gear assembly is connected to the rotating disk, the worm in the worm gear assembly is rotatably connected to the mounting disk, and several sliding members are slidably connected between the mounting disk and the rotating disk. Each sliding member is slidably connected to a roller.

[0007] More preferably, the rotating disk guides the sliding component.

[0008] More preferably, rollers are used to reduce friction between the rollers and the inner tube being repaired.

[0009] More preferably, the connecting assembly includes connecting cylinders, fasteners, and connecting rods. Several connecting cylinders are fixed to both sides of the mounting plate, and each connecting cylinder is threaded with a fastener. Several connecting rods are inserted into the corresponding connecting cylinders on the two mounting plates.

[0010] More preferably, the curing assembly includes a UV curing component and a wire. The UV curing component is installed between the connecting rods, and the end of the UV curing component is connected to a wire. The wire passes through the rotating disk to facilitate connection with the next set.

[0011] Compared with the prior art, the advantages of this utility model are: the number of mounting plates can be adjusted by connecting components according to the size of the pipe to be repaired and the inner pipe, the connecting rod is inserted into the connecting cylinder of the adjacent mounting plate, and the fastener is rotated to lock, so that the length of the device can be adapted to the repair needs without replacing the entire set of equipment, adapting to various specifications of pipes and reducing costs.

[0012] In this invention, the opening component uses a worm gear to drive a rotating disk, which guides the sliding component to move outward at a uniform speed to open the inner tube, thus preventing deformation of the inner tube. The rollers on the sliding component reduce friction and prevent scratching the inner tube. They also assist in smooth movement when adjusting the position of the device later.

[0013] In this invention, the UV curing component is connected and arranged with the installation plate, and multiple sets of components are connected in series by wires to achieve synchronous irradiation, ensuring uniform curing of the inner tube. The UV curing speed is faster than traditional heat curing, shortening the cycle and improving the strength and sealing of the repaired pipe. Attached Figure Description

For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; or internal connections between two components.

[0023] Furthermore, it should be understood in the description of this utility model that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.

[0024] Example: As shown in the attached figure, a CIPP pipe thermosetting repair device includes an installation plate 1 and a connector 11. The connectors 11 are symmetrically arranged and fixed to the side of the installation plate 1. The device also includes a spreading component, a connecting component, and a curing component. The spreading component is used to spread the inner pipe for repair. The connecting component is used to connect several installation plates 1 according to the length of the inner pipe for repair. The curing component is used to cure the inner pipe for repair.

[0025] In this embodiment, the spreading assembly specifically includes a rotating disk 2, a worm gear assembly 3, sliding members 4, and rollers 5. The rotating disk 2 is rotatably connected to the mounting disk 1. The worm gear in the worm gear assembly 3 is connected to the rotating disk 2, and the worm in the worm gear assembly 3 is rotatably connected to the mounting disk 1. Several sliding members 4 are slidably connected between the mounting disk 1 and the rotating disk 2. The rotating disk 2 guides the sliding members 4. When the rotating disk 2 rotates, the sliding members 4 move outward to support the repair inner tube. Each sliding member 4 is slidably connected to a roller 5, which reduces friction with the repair inner tube. Further, the connecting assembly includes connecting cylinders 6, fasteners 7, and connecting rods 8. Several connecting cylinders 6 are fixed to both sides of the mounting disk 1, and each connecting cylinder 6 is threadedly connected to a fastener 7. Several connecting rods 8 are inserted into corresponding connecting cylinders 6 on two mounting disks 1, and the connecting rods 8 are used to connect the two mounting disks 1. Furthermore, the curing assembly includes a UV curing component 9 and a wire 10. The UV curing component 9 is installed between the connecting rods 8 and is used to cure and repair the inner tube. The end of the UV curing component 9 is connected to the wire 10, which passes through the rotating disk 2 for easy connection to the next set.

[0026] When using the CIPP pipe thermosetting repair device, first determine the number of mounting plates 1 to be connected based on the length of the pipe to be repaired and the size of the inner tube to be repaired, using the connecting components. Insert both ends of the connecting rod 8 into the connecting cylinders 6 fixed to both sides of the two mounting plates 1, and then rotate the threaded fasteners 7 on each connecting cylinder 6 to press against the connecting rod 8, locking the connecting rod 8 to the connecting cylinder 6. This completes the stable connection of multiple mounting plates 1, ensuring that the overall length of the device is adapted to the inner tube to be repaired, meeting the repair needs of pipes of different lengths.

[0027] Next, the connected device is fitted with the repair inner tube, and the connecting piece 11 fixed to the side of the mounting plate 1 is securely connected to the external traction equipment. Then, the spreading assembly is operated to spread the repair inner tube, and the traction equipment is started. The device is driven by the connecting piece 11 to slowly move inside the inner tube to solidify the pipeline. The worm gear connected to the mounting plate 1 is rotated, and the worm gear drives the worm wheel that cooperates with it to rotate. The worm wheel is connected to the rotating disk 2 connected to the mounting plate 1, so the rotating disk 2 rotates synchronously with the worm wheel. Since several sliding parts 4 are slidably connected between the mounting plate 1 and the rotating disk 2, and the rotating disk 2 guides the sliding parts 4, the rotation of the rotating disk 2 will drive the sliding parts 4 to move outward. The sliding parts 4 push against the inner wall of the repair inner tube, spreading the repair inner tube until it is in contact with the inner wall of the pipeline to be repaired. At the same time, the roller 5 slidably connected to the sliding parts 4 contacts the repair inner tube, which can reduce the friction between the device and the repair inner tube, avoid damage to the repair inner tube during the spreading process, and facilitate subsequent adjustment of the position of the device in the repair inner tube.

[0028] After the inner tube is opened, the curing assembly is activated to cure it. The UV curing assembly 9, installed between the connecting rods 8, begins operation, using ultraviolet light to irradiate and cure the inner tube, ensuring a tight bond between the inner tube and the pipe to be repaired, thus achieving pipe repair. The wire 10 connected to the end of the UV curing assembly 9 passes through the rotating disk 2. If multiple sets of mounting disks 1 are connected, the wire 10 can connect to the next set of UV curing assemblies 9, ensuring that multiple sets of UV curing assemblies 9 operate synchronously, guaranteeing uniform curing of all parts of the inner tube, and improving the curing effect and repair quality.

[0029] Throughout the repair process, the connecting components flexibly adapt to repair needs of different lengths, the spreading components achieve stable spreading and protection of the repaired inner tube, and the curing components ensure uniform curing of the repaired inner tube. All components work together to greatly improve the efficiency and reliability of CIPP pipe thermosetting repair, and are suitable for repair scenarios of various pipe specifications.

[0030] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
