[0002] Domestic drainage pipes, rainwater pipes and industrial pipes, etc., after years of use, will inevitably suffer various damages and leaks due to erosion and corrosion by the medium, coupled with inadequate operation and management. If not repaired in time, it will cause immeasurable losses and harm.

[0003] Replacing the pipes with new ones is not only a massive and expensive undertaking, but also requires a long construction period, potentially impacting both people's lives and industrial operations. To address this issue, a pipeline repair method is currently available: UV-curing pipe repair. This involves laying a UV-curing hose inside the pipe to be repaired. The UV-curing hose is then fixed to the damaged area of the pipe, utilizing the optical reaction between the UV light and the hose to achieve repair.

[0004] However, the UV-curing hose is a soft material. After being laid in the pipeline, the UV-curing hose itself will become soft and collapse. When ultraviolet light is irradiated on the UV-curing hose, the soft and collapsed part of the UV-curing hose will be cured. The UV-curing hose cannot effectively repair the damaged part of the pipeline, resulting in failure of pipeline repair.

[0053] The working principle of the driving wheel 10 is the same as that of the rear wheel of the two-wheeled electric vehicle; the lamp body 6 is fixed on the disc 7, and the ultraviolet lamp 1 light emitted by the lamp body 6 irradiates the ultraviolet curing hose 3, curing the ultraviolet curing hose 3; the conductive wire of the driving wheel 10 is laid along the inside of the tube body 8 and is connected to an external power supply to control the rotation of the driving wheel 10. The driving wheel 10 is attached to the cured ultraviolet curing hose 3 and pushes the lamp body 6 forward. While the lamp body 6 cures the ultraviolet curing hose 3, it moves forward, and at the same time the supporting assembly is pulled backward; the setting of the driving assembly makes the axis of the disc 7 tend to the axis of the pipe 2, and the ultraviolet lamp 1 emitted by the lamp body 6 can irradiate the ultraviolet curing hose 3 as evenly as possible, ensuring the uniformity of curing of the ultraviolet curing hose 3;

[0054] The UV curing hose 3 that has not been irradiated by the UV lamp 1 is still soft, and part of the UV curing hose 3 may collapse and fall. If the collapse is too large, the resistance between the collapsed part and the supporting capsule 4 is large, and the supporting capsule 4 will press against the UV curing hose 3 in the collapsed part, and the UV curing hose 3 will be pulled and deformed, causing the UV curing hose 3 to move in the pipe 2, or the UV curing hose 3 to be pulled and deformed, and partially thinned. These are not conducive to the UV curing hose 3 repairing the damaged part of the pipe 2. For this purpose, a plurality of auxiliary capsules 11 are provided, and the diameter of the auxiliary capsules 11 is set so that when the supporting capsules 4 move in the UV curing hose 3, the auxiliary capsules 11 can smoothly support and lift the collapsed UV curing hose 3, and finally be squeezed and attached to the pipe 2 by the supporting capsule 4, to ensure that the UV curing hose 3 is cured in the pipe 2 in a flat state when being cured by the UV lamp 1, thereby ensuring the quality of the repair of the pipe 2;

[0055] The air pipe 12 connected to the auxiliary sac 11 with the smallest diameter is connected to the external pump body, and the pump body injects the lubricating liquid into the auxiliary sac 11 with the smallest diameter, and then the lubricating liquid is discharged from the air jet hole 13 on the auxiliary sac 11 with the smallest diameter, and the lubricating liquid is sprayed in the UV curing hose 3. When the auxiliary sac 11 and the supporting sac 4 that move subsequently pass through the surface of the UV curing hose 3 sprayed with the lubricating liquid, the auxiliary sac 11 and the supporting sac 4 can slide smoothly, thereby reducing the resistance between the supporting sac 4 and the auxiliary sac 11 and the UV curing hose 3, and improving the smoothness of movement of the supporting assembly; while the other auxiliary sacs 11 that are not injected with lubricating liquid are injected with air, and the air is ejected from the air jet hole 13, and the gas impacts the collapsed part of the UV curing hose 3, causing the collapsed part to shake, which helps the auxiliary sac 11 to slide to the collapsed part and support and lift up the collapsed part;

[0056] A squeezing assembly is provided. When the disc 7 moves in the UV-curing hose 3, the squeezing wheel 15 squeezes the surface of the UV-curing hose 3, further squeezing the UV-curing hose 3 into the pipe 2. This also prevents the UV-curing hose 3 between the lamp body 6 and the support assembly from slightly collapsing when the support assembly is far away from the lamp body 6. The elasticity of the support plate 14 squeezes the squeezing wheel 15 against the surface of the UV-curing hose 3. When the lamp body 6 irradiates the UV-curing hose 3, the irradiated portion of the UV-curing hose 3 is flat and smooth, and firmly adheres to the pipe 2, thereby improving the tightness of the adhesion between the UV-curing hose 3 and the pipe 2.

[0057] The support sheet 16 and the extrusion wheel 15 have the same function of squeezing the UV curing hose 3 onto the pipe 2. The end of the support sheet 16 is close to the area illuminated by the lamp body 6. When the UV curing hose 3 is cured, it further squeezes the UV curing hose 3 against the inner wall of the pipe 2.

[0058] The spray hole 17 is connected to the material pipe 18, and the material pipe 18 is connected to the external pump body. The pump body injects the lubricating liquid into the material pipe 18 and discharges it from the spray hole 17. The lubricating liquid is evenly sprayed on the surface of the UV curing hose 3. The support capsule 4 and the extrusion wheel 15 will scrape the lubricating oil on the inner surface of the UV curing hose 3, which will scrape off the lubricating liquid. For the support sheet 16, the resistance between the support sheet 16 and the UV curing hose 3 is relatively large, and the problem of pulling the UV curing hose 3 may also occur. For this reason, the spray hole 17 is provided. The spray hole 17 sprays the lubricating liquid, and the lubricating liquid lubricates the space between the support sheet 16 and the UV curing hose 3.

[0059] The disc 7 is also provided with a motor, the output end of the motor is fixedly connected to a gear 28, and the gear 28 meshes and rubs the inner gear ring 27 to rotate; the diameters of the pipes 2 are different, and when the extrusion wheel 15 is placed in the UV-curing hose 3, the diameter of the circle surrounded by the outer edge of the extrusion wheel 15 is larger than the diameter of the pipe 2, so that the extrusion wheel 15 can achieve the extrusion of the UV-curing hose 3; in order to facilitate the sliding of multiple extrusion wheels 15 into the UV-curing hose 3 and adapt to the repair of pipes 2 with different diameters, one end of the support plate 14 is rotatably connected to the disc 7 through a torsion spring 21, so that when the support plate 14 is in the initial state, the other end of the support plate 14 deflects toward the axis of the disc 7, so that the circle surrounded by the edge of the extrusion wheel 15 is larger than the diameter of the pipe 2. The diameter is smaller than the diameter of the pipe 2, which facilitates the rotation of the extrusion wheel 15 into the UV curing hose 3; after the extrusion wheel 15 is placed in the UV curing hose 3, the control motor drives the gear 28 to rotate, the gear 28 drives the inner gear ring 27 to rotate, the inner gear ring 27 mobilizes the inclined block 29 to rotate, the inclined surface of the inclined block 29 squeezes the inclined surface of the push rod 24, and pushes the push rod 24 toward the support assembly direction, the push rod 24 pushes the ball 26 through the arc plate 25, the ball 26 together with the connecting rod and the support plate 14 swing toward the UV curing hose 3, at this time the other end of the support plate 14 squeezes the extrusion wheel 15 on the surface of the UV curing hose 3, and squeezes the UV curing hose 3 to adhere to the inner wall of the pipe 2.
