[0002] Pipelines are prone to damage during long-term use, leading to problems such as leakage, pollution and pipeline collapse, so they need to be repaired in a timely manner.
[0003] The lining repair method is usually used for pipeline repair. The main steps of the repair are: the staff uses a scraper to evenly apply the resin that has been prepared and stirred in proportion to the glass fiber cloth, and wraps the glass fiber cloth on the outside of the expansion bag; pulls the expansion bag to the area where the pipeline is damaged and needs to be repaired; inflates the expansion bag to make the expansion bag expand so that the glass fiber cloth coated with resin fits the inner wall of the pipeline; the ultraviolet lamp in the expansion bag irradiates the glass fiber cloth to solidify the glass fiber cloth; finally, deflates the expansion bag and pulls the expansion bag out of the pipeline.
[0004] With respect to the above-mentioned related technologies, the inventor believes that when there are multiple areas in the pipeline that need to be repaired, the above steps need to be repeated, resulting in low efficiency in pipeline repair. Summary of the invention

[0040] Reference Figure 1 and Figure 3 The repair unit 21 includes a first mounting seat 211, a second mounting seat 212, and a connecting structure 213 connecting the first mounting seat 211 and the second mounting seat 212. The first mounting seat 211 has a first mounting portion 2111 for sealing and mounting one end of the UV repair sleeve 1, and the second mounting seat 212 has a second mounting portion 2121 for sealing and mounting the other end of the UV repair sleeve 1.
[0041] Reference Figure 2 and Figure 4 In order to make the second light shielding layer 13 better fit the inner surface of the UV repair layer 11, the first mounting portion 2111 is provided with a first arrangement ring 2112 for supporting the second light shielding layer 13 and a first driving cylinder 2113 for driving the first arrangement ring 2112 to move axially at the inner end surface. When the UV repair sleeve 1 is inflated, the first driving cylinder 2113 drives the first arrangement ring 2112 to move away from the UV repair sleeve 1, so that the first arrangement ring 2112 is separated from the second light shielding layer 13, thereby reducing the probability of the first arrangement ring 2112 interfering with the second light shielding layer 13 when the UV repair sleeve 1 is inflated.
[0042] Reference Figure 2 and Figure 5The second mounting portion 2121 is provided with a second arrangement ring 2122 for supporting the second light shielding layer 13 and a second driving cylinder 2123 for driving the second arrangement ring 2122 to move axially at the inner end surface. When the UV repair sleeve 1 is inflated, the second driving cylinder 2123 drives the second arrangement ring 2122 to move in a direction away from the UV repair sleeve 1, so that the second arrangement ring 2122 is separated from the second light shielding layer 13, thereby reducing the probability of the second arrangement ring 2122 interfering with the second light shielding layer 13 when the UV repair sleeve 1 is inflated.
[0043] Reference Figure 4 and Figure 5 In order to achieve ideal sealing when the UV repair sleeve 1 is installed on the first mounting portion 2111 and the second mounting portion 2121, a first sealing ring groove 2114 is circumferentially provided on the outer side surface of the first mounting portion 2111, and a first sealing ring 2115 is provided at the first sealing ring groove 2114.

An air supply pipe connected to the air supply device 4 is arranged in the connection pipe 2132, and the air supply pipe is connected to the air supply head 2131. When the air supply device 4 inflates the UV repair sleeve 1 through the air supply head 2131 so that the UV repair sleeve 1 expands and the curing area 14 adheres to the inner wall of the pipe, the ultraviolet lamp assembly 2133 irradiates the UV repair sleeve 1. Since the inner surface of the UV repair layer 11 is covered with the second light shielding layer 13, the curing area 14 is cured.
[0045] Reference Figure 1 and Figure 3The moving assembly 22 includes three moving legs 221 that are evenly spaced circumferentially hinged to the first mounting seat 211 / the second mounting seat 212. The moving legs 221 are arranged obliquely toward the center area away from the repair and curing trolley 2.

One end of the moving torsion spring 223 abuts against the first mounting seat 211 / the second mounting seat 212 and the other end abuts against the moving leg 221 installed on the first mounting seat 211 / the second mounting seat 212.
