Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline repair, and relates to a trenchless repair device and process for a water supply network. Background Art

[0002] Over the long term, urban water supply networks can experience damage. Excavation repair is a common repair method, but it suffers from low efficiency, high costs, and significant environmental pollution. Trenchless construction utilizes various geotechnical drilling equipment and techniques, using guided and directional drilling methods to lay, replace, and repair underground pipelines with minimal surface excavation. This approach eliminates traffic obstructions, damages green spaces and vegetation, and disrupts the normal work and life of businesses, hospitals, schools, and residents. Consequently, it boasts high socioeconomic benefits and has become a new approach to pipeline repair. UV-CIPP is an advanced trenchless pipeline repair technology that cures a specialized high-strength resin hose inside the existing pipeline. This technology offers advantages such as rapid installation, short construction times, high quality, a tight fit between the liner and the pipe, and minimal loss of flow area. UV-CIPP has been widely used in pipeline repair projects both domestically and internationally.

[0003] When repairing pipes, for pipes with larger inner diameters, the ultraviolet light source will be farther away from the material, and the light intensity received by the material per unit time will be smaller, affecting the curing efficiency.

[0004] In order to solve the above problems, the present invention proposes a trenchless repair device and process for a water supply network. Summary of the Invention

The sliding sleeve is gradually sleeved on the swing rod, thereby causing the sliding light bar to approach the fixed light bar. When the sliding light bar and the fixed light bar come into contact, the spring rod extends as the limit rod continues to slide in the inclined hole. When the limit rod is at the end of the inclined hole, the rotating disk drives the sliding sleeve to rotate through the limit rod, and the light source assembly rotates around the shaft.

[0014] Furthermore, a connecting ring is provided at the end of the shaft.

[0015] A trenchless repair process for a water supply network in the present invention comprises the following steps: S1. Place the liner tube into the pipeline and make it fit the pipeline; S2, placing the repair device into the liner tube and moving the device to a suitable position; S3. Start the fixed light bar and the sliding light bar, causing the rotating disk to rotate. The limit rod slides in the inclined hole in a direction away from the shaft rod, causing the sliding sleeve to slide along the support member close to the slide rail. The sliding sleeve is gradually sleeved on the swing rod, thereby causing the sliding light bar to approach the fixed light bar. When the sliding light bar and the fixed light bar come into contact, as the limit rod continues to slide in the inclined hole, the spring rod extends, and the light source assembly moves close to the inner wall of the pipe; S4.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1-10 As shown, the technical solution adopted by the present invention is as follows: a trenchless repair device for a water supply network includes a shaft 1, a light source assembly and a walking mechanism.

[0022] The travel mechanism is mounted on the shaft 1 and is used to drive the shaft 1 to move within the pipeline. The travel mechanism includes hydraulic rods 24 and rollers 25. Multiple hydraulic rods 24 are mounted on the outer circumference of each end of the shaft 1. One end of each hydraulic rod 24 is fixedly connected to the shaft 1, and the other end of each hydraulic rod 24 rotates with a roller 25. The axis of the roller 25 is perpendicular to the axis of the shaft 1.

[0023] Both ends of the shaft 1 are connected with connecting rings 2, and the connecting rings 2 are used to connect the two repair devices.

[0024] A rotating sleeve 5 is coaxially rotated on the shaft 1. Specifically, a bearing 3 is installed on the shaft 1, and the rotating sleeve 5 is connected to the bearing 3 through a connecting rod 4.

[0025] There are multiple light source assemblies, and the multiple light source assemblies are distributed in an array along the axis of the shaft 1. In this embodiment, there are four light source assemblies, and the four light source assemblies are distributed in an array along the axis of the shaft 1.

[0026] Each light source assembly includes a slide rail 15, a fixed light bar 16 and a sliding light bar 18. Each light source assembly includes two slide rails 15, the slide rails 15 are arc-shaped, and the inner concave surface of the slide rails 15 faces the shaft 1. The slide rails 15 move away from or close to the shaft 1. The fixed light bar 16 is fixed between the two slide rails 15 and the fixed light bar 16 is fixedly connected to the middle of the slide rails 15. The sliding light bar 18 is slidably connected between the two slide rails 15. There are two sliding light bars 18, and the two sliding light bars 18 are arranged on both sides of the fixed light bar 16. The end of the sliding light bar 18 is fixedly connected to a conductive block 17, which is slidably set in the slide rail 15. A conductive sheet that cooperates with the conductive block 17 is provided in the slide rail 15.

[0027] Each slide rail 15 is connected to the shaft 1 through a support member. The support member includes a fixed rod 14, a sliding rod 11 and a spring rod 12. Two rotating blocks 13 are rotatably provided on the shaft 1, and the two slide rails 15 in the same light source assembly correspond one-to-one to the two rotating blocks 13. There is a certain rotational damping between the rotating blocks 13 and the shaft 1. One end of the fixed rod 14 is fixedly connected to the middle of the slide rail 15, and the other end of the fixed rod 14 is fixedly connected to the sliding rod 11. The sliding rod 11 is fixedly connected to one end of the spring rod 12, and the spring rod 12 is connected to the corresponding rotating block 13. A sliding hole 6 is provided on the rotating sleeve 5, and the sliding rod 11 passes through the sliding hole 6.

[0028] The sliding light bar 18 is connected to the slide bar 11 via a swing arm 19. One end of the swing arm 19 is hinged to the slide bar 11 via a hinge axis, while the other end is connected to the sliding light bar 18. A torsion spring is mounted on the hinge axis and fixedly connected between the slide bar 11 and the swing arm 19. The torsion spring forces the two swing arms 19 to open, positioning the sliding light bar 18 at the end of the slide rail 15. This creates a gap between the fixed light bar 16 and the sliding light bar 18.

[0029] The sliding sleeve 7 is provided on the sliding rod 11. The sliding sleeve 7 moves along the sliding rod 11 toward the sliding rail 15, so that the sliding rail 15 is gradually sleeved on the swing rod 19. The swing rod 19 rotates toward the middle fixed rod 14, and the sliding light bar 18 moves toward the fixed light bar 16, thereby increasing the light intensity of the light source assembly.

[0030] Both ends of the rotating sleeve 5 are rotatably connected to a rotating disk 9, which is coaxially arranged with the rotating sleeve 5. A through hole is formed in the rotating disk 9. The rotational damping between the rotating disk 9 and the rotating sleeve 5 is smaller than the rotational damping between the rotating block 13 and the shaft 1.

[0031] The shaft 1 is equipped with drive assemblies that drive the rotating disk 9. Each drive assembly includes a motor 21, a gear 22, and a ring gear 23. The motor 21 is fixedly mounted on the shaft 1, the gear 22 is coaxially fixedly mounted on the output shaft of the motor 21, and the ring gear 23 is coaxially fixedly connected to the rotating disk 9, with the gear 22 and the ring gear 23 meshing.

[0032] The rotating disk 9 is provided with an inclined hole 10. One end of the inclined hole 10 is tilted away from the shaft 1. In this embodiment, each rotating disk 9 has four inclined holes 10, arranged in an array along the axis of the shaft 1. The sliding sleeve 7 is connected to a limit rod 8, which slides within the corresponding inclined hole 10.

[0033] Light collecting covers 20 are provided on both sides of the slide rail 15 .

[0034] Working principle: Initially, Figure 1 As shown, the limiting rod 8 is located at one end of the inclined hole 10 close to the axis of the rotating disk 9. The sliding light bar 18 is located at the end of the slide rail 15.

[0035] Place the liner pipe into the pipe to be repaired and fit the liner pipe to the pipe.

[0036] Then the repair device is placed into the pipeline and moved to a suitable position through a walking mechanism.

[0037] Then, start the fixed light bar 16 and the sliding light bar 18. If the inner diameter of the pipe is small, start the motor 21 to rotate the rotating disk 9 clockwise. The rotating disk 9 drives the limit rod 8 to rotate through the inclined hole 10, and the sliding sleeve 7 rotates, the rotating sleeve 5 rotates, and the light source assembly rotates around the shaft 1, thereby providing comprehensive and uniform lighting to the inner lining pipe.

[0038] If the inner diameter of the pipe is large, start the motor 21 to rotate the rotating disk 9 counterclockwise. Initially, because the rotational damping between the rotating block 13 and the shaft 1 is greater than the rotational damping between the rotating disk 9 and the rotating sleeve 5, the rotating disk 9 rotates while the rotating sleeve 5 remains stationary. The limiting rod 8 slides along the inclined hole 10. Under the guidance of the inclined hole 10, the limiting rod 8 moves away from the axis of the rotating disk 9, causing the sliding sleeve 7 to slide along the sliding rod 11 in a direction away from the shaft 1, and the sliding sleeve 7 moves toward the slide rail 15. The sliding sleeve 7 is gradually sleeved on the swing rod 19, causing the two swing rods 19 to rotate in a direction close to the fixed rod 14, thereby causing the sliding light bar 18 to slide close to the fixed light bar 16. The sliding light bar 18 is close to the fixed light bar 16, which is conducive to increasing the light intensity and improving the curing efficiency.

[0039] When the sliding light bar 18 contacts the fixed light bar 16, the sliding sleeve 7 abuts against the slide rail 15. As the limiting rod 8 continues to slide along the inclined hole 10, it moves further away from the axis of the rotating disk 9, causing the sliding sleeve 7 to slide further away from the shaft 1, extending the spring rod 12 and moving the light source assembly closer to the inner wall of the liner tube. This reduces the distance between the fixed and sliding light bars 16, 18, and the inner wall of the liner tube, thereby increasing light intensity and improving curing efficiency.

[0040] Until the limiting rod 8 is at the end of the inclined hole 10 away from the axis of the rotating disk 9, and then the rotating disk 9 drives the limiting rod 8 to rotate through the inclined hole 10, the sliding sleeve 7 rotates around the shaft 1, and the light source assembly rotates around the shaft 1 to provide comprehensive and uniform illumination to the inner lining tube.

[0041] When it is necessary to position the sliding light bar 18 at the end of the slide rail 15, that is, to position the limiting rod 8 at the end of the inclined hole 10 near the axis of the rotating disk 9, the rotating disk 9 rotates clockwise, and the limiting rod 8 slides toward the end of the inclined hole 10 near the axis of the rotating disk 9, and the sliding sleeve 7 moves closer to the shaft 1. The swing rod 19 and the spring rod 12 reset, and when the limiting rod 8 is at the end of the inclined hole 10 near the axis of the rotating disk 9, the light source assembly returns to its initial state. Therefore, when illuminating a pipe with a smaller inner diameter, the rotating disk 9 can be rotated clockwise, and when illuminating a pipe with a larger inner diameter, the rotating disk 9 can be rotated counterclockwise, making operation simple and convenient.

[0042] A trenchless repair process for a water supply network in the present invention comprises the following steps: S1. Place the liner tube into the pipeline and make it fit closely with the pipeline.

[0043] S2. Place the repair device into the liner tube and move the device to a suitable position.

[0044] S3. Start the fixed light bar 16 and the sliding light bar 18 to rotate the rotating disk 9. The limiting rod 8 slides in the inclined hole 10 in the direction away from the shaft 1, so that the sliding sleeve 7 slides along the support member close to the slide rail 15. The sliding sleeve 7 is gradually sleeved on the swing rod 19, and then the sliding light bar 18 is close to the fixed light bar 16. When the sliding light bar 18 and the fixed light bar 16 are in contact, as the limiting rod 8 continues to slide in the inclined hole 10, the spring rod 12 extends, and the light source assembly moves close to the inner wall of the pipe.

[0045] S4 , the limiting rod 8 is at the end of the inclined hole 10 , the rotating disk 9 drives the sliding sleeve 7 to rotate through the limiting rod 8 , and the light source assembly rotates around the shaft 1 .

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
