[0002] UV curing, that is, ultraviolet curing, where UV is the English abbreviation of ultraviolet, and curing refers to the process of a substance changing from a low molecule to a high molecule. UV curing generally refers to the curing conditions or requirements for coatings (paints), inks, adhesives (glues), or other potting and sealing agents that need to be cured by ultraviolet light, which is different from heat curing, curing with cross-linking agents (curing agents), natural curing, etc.

[0003] During the processing of curing some pipelines, sometimes it is not convenient to use an excavation device. Therefore, a new pipeline is embedded in the inner wall of the original pipeline, and then the new pipeline is cured by a curing device.

[0004] The existing non-excavation repair device for ultraviolet curing of pipelines is not easy to conveniently adapt to pipelines of different sizes, and it is difficult to install the device at the center of the working pipeline and evenly irradiate the working pipeline, which may lead to a decrease in the adaptability of the device. The existing non-excavation repair device for ultraviolet curing of pipelines is not easy to achieve the effect of conveniently disassembling and assembling the device, which may lead to a decrease in the maintenance efficiency during use.

[0005] Therefore, in view of the above problems, a non-excavation repair device for ultraviolet curing of pipelines is proposed. Content of the Utility Model
