Description

Technical Field

[0001] The present application relates to the technical field of ultraviolet light curing for pipeline repair, and in particular to an ultraviolet light curing device for pipeline repair. Background Art

[0002] When repairing pipelines, pipe replacement or patching is generally adopted. The UV-curing trenchless lining repair technology for pipelines refers to adding a photoinitiator (or photosensitizer) to a specially formulated system, placing an ultraviolet lamp of a specific wavelength into an inflated hose, and controlling the ultraviolet lamp to move at a certain speed in the hose to generate active free radicals or cations, thereby initiating polymerization, cross-linking and grafting reactions, causing the hose to transform from a liquid to a solid state within a certain period of time. The hose is gradually solidified from one end to the other, clinging to the inner wall of the pipeline to be repaired, forming a hard "pipe-in-pipe" structure, thereby repairing underground pipelines that have been damaged or have lost their transportation function in situ.

[0003] When a pipeline is partially damaged, the existing technology generally requires excavation of the leakage point, followed by repair, and then burial. However, the excavation and burial cause the pipeline repair process to take a long time, resulting in a large waste of manpower and material resources. Utility Model Content
