Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipeline repair, in particular to a drainage pipeline trenchless ultraviolet curing repair device. Background Art

[0002] With the continuous acceleration of urbanization, administrative departments have gradually strengthened their supervision over the construction of pipelines. After a large number of underground pipelines have been put into operation for several years, perforation or leakage accidents will inevitably occur due to external forces or their own service life. Traditional treatment methods are generally excavation repair or replacement. The old pipelines are basically located under the main roads of the city or on the edge of the structures. Repair or replacement will involve many factors such as road administration, removal and repair of bottom obstacles, and public coordination. When local damage to the pipeline causes overall operational ineffectiveness, the overall replacement will cost too much. Therefore, a non-excavation UV curing repair device for drainage pipes is needed.

[0003] According to patent CN 220016567 U, a pipeline UV-curing trenchless repair device includes multiple mobile units and multiple support frames with different diameters. The mobile units are provided with ultraviolet lamps and connecting components. The multiple mobile units are detachably installed on any support frame through the connecting components. The support frame includes an annular ring frame, and the inside of the ring frame is fixedly connected to an inner support member. A connecting member is fixedly connected to the inner support member and located at the axis of the ring frame.

[0004] This patent can adapt to pipe wells of different diameters by setting up multiple support frames with different diameters in conjunction with an integrated mobile unit and ultraviolet lamps, and the structure is relatively simple. However, if this patent is to be adjusted according to the diameters of different pipes, four sets of screws need to be rotated separately, which is time-consuming and labor-intensive, and it may not be possible to adjust the four sets of rollers to a position that completely matches the pipe diameter.
