Description

Technical Field

[0001] This invention relates to the field of pipeline repair technology, and in particular to a trenchless pipeline repair device and method using ultraviolet light curing. Background Technology

[0002] Pipeline repair typically involves replacing or patching the pipe. Ultraviolet (UV) curing trenchless lining repair technology involves adding a photoinitiator (or photosensitizer) to a specially formulated system, placing a UV lamp of a specific wavelength inside an inflatable flexible tube, and controlling the lamp's movement within the tube at a certain speed. This generates active free radicals or cations, initiating polymerization, cross-linking, and grafting reactions, transforming the liquid into a solid state within a specific timeframe. The flexible tube gradually solidifies from one end to the other, adhering tightly to the inner wall of the pipe to be repaired, forming a hard "pipe-in-pipe" structure. This allows damaged or disused underground pipelines to be repaired in situ. However, this technology generally requires spraying liquid onto the flexible tube and manually controlling the UV lamp's irradiation and movement, which is inconvenient. Therefore, a device and method were designed that allows for controlled UV lamp movement, convenient liquid spraying, and accelerated curing via air blowing. Summary of the Invention

[0049] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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 the invention.

[0050] Example 1:

[0051] A trenchless pipeline repair UV curing device includes a cylinder 1 and a UV lamp ring 5, wherein the UV lamp ring 5 is fixed to the outer wall of the cylinder 1, characterized in that:

[0052] The curing module 3, connected to the cylinder 1, is used for cooling;

[0053] A drive motor 12 is disposed outside the cylinder 1, and the drive motors 12 are evenly arranged around the circumference;

[0054] Mecanum wheel 13 is disposed outside the cylinder 1 and connected to the drive motor 12;

[0055] The position adjustment module is connected to the drive motor 12.

[0056] The use of Mecanum wheel 13 enables omnidirectional movement. Mecanum wheel 13 is based on the principle of a central wheel with many axles located around the wheel. These angled peripheral axles convert a portion of the wheel steering force into a wheel normal force.

[0057] Relying on the direction and speed of each wheel, the final synthesis of these forces produces a resultant force vector in any required direction, thus ensuring that the platform can move freely in the direction of the final resultant force vector without changing the direction of the wheels themselves. Many small rollers are obliquely distributed on its rim, so the wheel can slide laterally. The generatrix of the small rollers is special. When the wheel rotates around a fixed wheel axis, the envelope of each small roller is a cylindrical surface, so the wheel can roll forward continuously. The Mecanum wheel 13 has a compact structure, flexible movement, and is an omnidirectional wheel. Combining three Mecanum wheels 13 can achieve omnidirectional movement more flexibly and conveniently.

[0058] The UV lamp ring 5 can irradiate UV light and react with the photoinitiator in the specially formulated curing solution to generate active free radicals or cations, thereby initiating polymerization, cross-linking and grafting reactions, which transform it from a liquid to a solid state within a certain time.

[0059] The position adjustment module includes a turntable 14, an L-shaped moving rod 15, a connecting rod 17, and a motor.

The other end of the U-shaped bracket 351 is fixed to the end of the vertical bar of the cross-shaped rod 35. The two ends of the horizontal bar of the cross-shaped rod 35 are fixed inside the cylinder 1.

[0060] The position adjustment module can adjust the position of the Mecanum wheel 13. In use, the output shaft of the control motor rotates, driving the turntable 14 to rotate. The turntable 14 drives the connecting rod 17 to swing, and the connecting rod 17 drives the L-shaped moving rod 15 to swing. Under the limit of the cylinder 1 on the L-shaped moving rod 15, the L-shaped moving rod 15 moves along the square hole passing through the cylinder 1. The L-shaped moving rod 15 drives the drive motor 12 and the Mecanum wheel 13 to move, thereby realizing the adjustment of the Mecanum wheel 13. The position of the Mecanum wheel 13 is adjusted according to the inner diameter of the pipe to be repaired.

The ends of the vertical rods 38 are rotatably connected to the horizontal plates 353. Each vertical rod 38 is passed through by the connecting rod 394 of the fan module 39. The outer end of each connecting rod 394 is fixed to the center of the baffle 395.

[0062] The curing module 3 can accelerate the curing speed by fanning the air through the fan module 39.

[0063] Each of the stop levers 395 has its two ends fixedly connected to the ball of universal joint 2 373. The ball groove of each universal joint 2 373 is fixedly connected to the ball of universal joint 1 371 through the fixing rod 372. One end of the protrusion 354 is fixed on both sides of the cross-shaped rod 35. Each protrusion 354 is passed through by the guide rod 34. One end of each guide rod 34 is fixedly connected to the center of the moving rod 37. The two ends of each moving rod 37 are fixed to the corresponding ball of universal joint 1 371.

[0064] The other end of the guide rod 34 is fixedly connected to the center of one side of the straight groove rod 32. Each straight groove rod 32 has a rotating shaft 33 in its groove. Each rotating shaft 33 is fixed to one side edge of the bevel gear 31. The central shaft of the bevel gear 31 is respectively connected to both sides of the cross-shaped rod 35. The bevel gear 31 meshes with the bevel gear 36. The central shaft of the bevel gear 36 is connected to one side of the U-shaped bracket 351. The output shaft of the motor 2 is fixedly connected to the center of the central shaft of the bevel gear 36. The motor 2 is fixed inside the motor cavity 2.

[0065] Motor 2 drives bevel gear 36, which in turn drives bevel gear 31 to rotate. Bevel gear 31 drives shaft 33 to rotate. Shaft 33 is located in the groove of straight rod 32. Shaft 33 drives straight rod 32 to reciprocate. Straight rod 32 drives guide rod 34 to reciprocate. Guide rod 34 reciprocates along the square hole passing through protrusion 354. Guide rod 34 drives moving rod 37 and universal joint 371 to reciprocate. Universal joint 371 drives universal joint 373 to reciprocate through fixed rod 372. The ball of universal joint 373 drives stop rod 395 and connecting rod 394 to reciprocate. Connecting rod 394 moves along the round hole passing through vertical rod 38. Fan module 39 moves through the connecting rod 394 to achieve fan operation.

[0066] The fan module 39 includes a circular plate 391, a cross link 392, a cross-shaped fan blade 393, and a connecting rod 394. The center of the circular plate 391 is fixed to the other end of the connecting rod 394, and the center of the other side of the circular plate 391 is fixedly connected to the center of the cross-shaped fan blade 393 through the cross link 392.

[0067] The connecting rod 394 of the fan module 39 moves, driving the circular plate 391, the cross connecting rod 392 and the cross-shaped fan blade 393 fixed thereto to move in a cycle, thereby realizing the movement of the cross-shaped fan blade 393 to fan the air.

[0068] The method of use is as follows: a hose sprayed with a special formula liquid containing a photoinitiator is placed into the pipeline to be repaired and inflated. The device is then placed inside the inflated hose. The position of the Mecanum wheel 13 is adjusted by the position adjustment module to make it fit against the pipeline wall. The drive motor 12 is controlled to drive the Mecanum wheel 13, allowing the device to move inside the pipeline. The ultraviolet lamp ring 5 emits ultraviolet light to induce the special formula liquid containing the photoinitiator to react and produce active free radicals or cations, thereby initiating polymerization, cross-linking, and grafting reactions. This technology transforms the liquid into a solid state within a certain period of time, allowing the hose to gradually solidify from one end to the other, adhering tightly to the inner wall of the pipeline to be repaired, forming a hard "pipe-in-pipe" structure. This allows underground pipelines that have been damaged or lost their transport function to be repaired in situ. During the movement of the device, the fan module 39 is controlled to work to accelerate the solidification reaction.

[0072] S3: Place this device into the inflated hose, and adjust the position of the Mecanum wheel 13 by adjusting the position adjustment module so that it fits against the pipe wall. During adjustment, the output shaft of the control motor rotates to drive the turntable 14 to rotate.

Under the limit of the cylinder 1 on the L-shaped moving rod 15, the L-shaped moving rod 15 moves along the square hole passing through the cylinder 1. The L-shaped moving rod 15 drives the drive motor 12 and the Mecanum wheel 13 to move, thereby realizing the adjustment of the Mecanum wheel 13.

[0073] S4: Control the operation of drive motor 12 and ultraviolet lamp ring 5. This device moves inside the pipeline, driving the ultraviolet lamp ring 5 to move, thereby achieving the curing of the hose.
