Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a point-like in-situ curing repair device. Background Art

[0002] Point-based in-situ curing is a trenchless repair method used when there are local cracks, leaks, or damage to pipelines, requiring emergency repairs. A fiberglass mat coated with a resin mixture is pressed tightly against the inner wall of the pipeline using an airbag, and curing is achieved through methods such as room temperature, heating, or ultraviolet irradiation, forming a new inner lining pipe at the repair point.

[0003] The existing device generally involves fixing an airbag covered with fiberglass mat to a mobile frame, moving the frame to the pipe repair site, then pressurizing the airbag to press the fiberglass mat tightly against the inner wall of the pipe, while ultraviolet lamps on both sides irradiate the repair site to achieve curing. However, the following problems exist in actual operation:

[0004] 1. To avoid wasting resources, existing devices adjust the size of the fiberglass mat according to the size of the pipe breakage. However, when repairing the pipe, the entire airbag needs to be pressurized and inflated regardless of the size of the area to be repaired. When the repair area is small, the time required for the airbag to be pressurized and inflated is long, which affects the efficiency of pipe repair and also causes unnecessary waste of resources.

[0005] 2. When using UV lamps fixed on both sides of the mobile frame to cover the repair area, since the UV lamps are fixed and cannot be moved, when the repair area is small, the distance between the UV lamps and the repair area is far, resulting in a lower curing effect on the repair area, which will increase the repair time and affect the repair efficiency. Utility Model Content

[0006] To address the aforementioned problems, the present invention aims to provide a point-based in-situ curing repair device that adjusts the size of the airbag requiring pressurization according to the size of the repair area, and simultaneously adjusts the distance between the ultraviolet lamp and the repair site, thereby improving the efficiency of pipeline repair.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A point-like in-situ curing repair device includes a repair frame, movable components symmetrically installed at the four corners of the repair frame, an airbag assembly sleeved on the outside of the repair frame, and a barrier assembly with both ends respectively sleeved on both sides of the airbag assembly and slidably connected to the airbag assembly. The barrier assembly includes a bidirectional lead screw horizontally installed inside the repair frame and rotatably connected to the repair frame, guide blocks symmetrically arranged at both ends of the bidirectional lead screw and slidably connected to the bidirectional lead screw, a pair of barrier rings symmetrically sleeved on the outside of the airbag assembly and fixed internally to the corresponding guide blocks to block the flow of gas inside the airbag assembly, and several ultraviolet lamps spaced apart on the outer surface of the barrier rings. The inner surface of the barrier rings is pressed tightly against the outside of the airbag assembly. A glass fiber cloth is wound around the outside of the airbag assembly, and the outside of the glass fiber cloth is coated with a photosensitive resin adhesive layer. The two barrier rings are respectively located on both sides of the glass fiber cloth.

[0009] More preferably, the airbag assembly includes a plurality of airbag strips fixed at intervals outside the repair frame, a connecting pipe disposed between the airbag strips for connecting the airbag strips, and an inflation / deflation port fixed to one side of any one airbag strip for connecting an external inflation mechanism.

[0010] More preferably, the movable component includes a support plate fixedly connected to the outer end of the repair frame, a damping telescopic rod fixed to the outside of the support plate, an electric swivel wheel fixed to the end of the damping telescopic rod, and a spring sleeved on the outside of the damping telescopic rod and installed between the support plate and the electric swivel wheel.

[0011] More preferably, cameras are installed at both ends of the repair frame.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of a bidirectional lead screw, guide block and barrier ring, can move the two barrier rings to both sides of the fiberglass cloth according to the size of the fiberglass cloth, and change the inflatable range of the airbag assembly accordingly. This avoids the need to inflate the entire airbag assembly when the repair area is small, thus increasing unnecessary inflation time, improving the efficiency of pipeline repair, and reducing resource waste.

[0014] 2. This utility model, through the cooperation of a bidirectional lead screw, guide block, barrier ring and ultraviolet lamp, can drive the ultraviolet lamp to move while the barrier ring moves, thereby reducing the distance between the ultraviolet lamp and the repair area, improving the curing efficiency of the repair area, reducing the repair time and improving the repair efficiency.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A point-like in-situ curing repair device includes a repair frame 1, movable components 2 symmetrically installed at the four corners of the repair frame 1, an airbag assembly 3 sleeved on the outside of the repair frame 1, and a barrier assembly 4 with both ends respectively sleeved on both sides of the airbag assembly 3 and slidably connected to the airbag assembly 3. The barrier assembly 4 includes a bidirectional lead screw 41 horizontally installed inside the repair frame 1 and rotatably connected to the repair frame 1, guide blocks 42 symmetrically arranged at both ends of the bidirectional lead screw 41 and slidably connected to the bidirectional lead screw 41, a pair of barrier rings 43 symmetrically sleeved on the outside of the airbag assembly 3 and fixed inside to the corresponding guide blocks 42 to block the flow of gas inside the airbag assembly 3, and a plurality of ultraviolet lamps 44 spaced apart on the outer surface of the barrier rings 43. The inner surface of the barrier rings 43 is pressed tightly against the outside of the airbag assembly 3. A glass fiber cloth 5 is wound around the outside of the airbag assembly 3, and the outside of the glass fiber cloth 5 is coated with a photosensitive resin adhesive layer 6. The two barrier rings 43 are respectively located on both sides of the glass fiber cloth 5.

[0021] By cooperating with the bidirectional screw 41, guide block 42, and barrier ring 43, the two barrier rings 43 can be moved to both sides of the fiberglass cloth 5 according to the size of the fiberglass cloth 5, thereby changing the inflatable range of the airbag assembly 3 accordingly. This avoids the need to inflate the entire airbag assembly 3 when the repair area is small, increasing unnecessary inflation time, improving the efficiency of pipeline repair, and reducing resource waste. By cooperating with the bidirectional screw 41, guide block 42, barrier ring 43, and ultraviolet lamp 44, the ultraviolet lamp 44 can be moved while the barrier ring 43 moves, reducing the distance between the ultraviolet lamp 44 and the repair site, improving the curing efficiency of the repair site, reducing repair time, and improving repair efficiency.

[0022] As a possible implementation of this solution, preferably, the airbag assembly 3 includes a plurality of airbag strips 31 fixed at intervals outside the repair frame 1, a connecting pipe 32 disposed between the airbag strips 31 for connecting the airbag strips 31, and an inflation / deflation port 33 fixed to one side of any airbag strip 31 for connecting an external inflation mechanism; by arranging a plurality of airbag strips 31 at intervals, while not affecting the pressurization of the fiberglass cloth 5, when the airbag assembly 3 is damaged, some airbag strips 31 can be replaced, avoiding the need to replace the entire airbag assembly 3 and reducing replacement costs.

[0023] As a possible implementation of this solution, preferably, the movable component 2 includes a support plate 21 fixedly connected to the outer end of the repair frame 1, a damping telescopic rod 22 fixed to the outside of the support plate 21, an electric universal wheel 23 fixed to the end of the damping telescopic rod 22, and a spring 24 sleeved on the outside of the damping telescopic rod 22 and installed between the support plate 21 and the electric universal wheel 23; through the cooperation of the damping telescopic rod 22, the spring 24 and the electric universal wheel 23, the repair frame 1 can remain in close contact with the inner wall of the pipe when it moves, avoiding collisions between the repair frame 1 and the inner wall of the pipe when it moves inside the pipe, thereby preventing damage to the repair device.

[0024] As a possible implementation of this solution, preferably, cameras 7 are installed at both ends of the repair frame 1; by setting up the cameras 7, when the repair device is used to repair the pipeline, the staff can have a better understanding of the condition of the inner wall of the pipeline, so as to ensure the correct repair position.

[0025] The working principle of this device is as follows:

[0026] When it is necessary to repair the damaged part of the pipeline, photosensitive resin adhesive is first applied to the surface of the fiberglass cloth 5 to form a photosensitive resin adhesive layer 6. Then, the fiberglass cloth 5 is wound around the middle of the outer side of several airbag strips 31. The guide block 42 and the barrier ring 43 are moved closer to the fiberglass cloth 5 by the motor-driven bidirectional lead screw 41 until the two barrier rings 43 abut against the two sides of the fiberglass cloth 5. Then, the airbag strip 31 located between the two barrier rings 43 is inflated by the inflation mechanism (such as an inflation and deflation airbag, an inflation lamp). This makes the photosensitive resin adhesive layer 6 on the outer side of the fiberglass cloth 5 press tightly against the inner wall of the pipeline where it needs to be repaired. The photosensitive resin adhesive layer 6 is irradiated by the ultraviolet lamp 44, which makes the photosensitive resin adhesive layer 6 solidify on the inner wall of the pipeline, thus completing the pipeline repair.

[0027] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
