[0024] See also Figure 1-4As shown, a UV curing device for trenchless repair of pipelines comprises a central square shaft 1; a driving plate 2 is fixedly connected to the central square shaft 1; a limiting slide groove 4 is arranged around the driving plate 2; a plurality of sliders 5 are inserted in the limiting slide groove 4; a first nut pair 6 is inserted in the slider 5; a symmetrical swing arm 7 is sleeved on the first nut pair 6; a second nut pair 16 is inserted at the end of the symmetrical swing arm 7; a movable plate 8 is sleeved on the second nut pair 16; a movable groove 9 is arranged on the movable plate 8; a block plate 10 is slotted and inserted in the movable groove 9; an ultraviolet lamp 11 is fixed to the block plate 10; a limiting plate 3 and a fixed plate 17 are rotatably sleeved at both ends of the central square shaft 1; the limiting plate 3 and the fixed plate 17 are rotatably sleeved on the two ... A supporting unit is provided on the plate 17; when working, it is first connected to the pipeline inspection robot, and then before entering the pipeline, the first nut pair 6 and the second nut pair 16 are rotated to change the angle between the symmetrical swing arm 7 and the movable plate 8 and the central square axis 1, so that the movable plate 8 and the ultraviolet lamp 11 fit the inner wall of the drainage pipe, thereby realizing close-range irradiation of the pipeline light-curing repair material for curing, so that under drainage pipes of different diameters, curing at the same distance and the same time can be achieved, thereby achieving the same curing effect, so that the effective curing time can be determined according to the repair area, which solves the problem that the existing light-curing device cannot adjust the distance between the light-curing repair material and the pipes of different diameters to ensure consistent curing effect.

[0025] The support unit includes multiple limiting sleeves 13; support plates 14 are slidably inserted in the multiple limiting sleeves 13; the ends of the support plates 14 are rotatably connected with rollers 15; the limiting sleeves 13 have holes and threads with nuts inserted therein; when working, the rollers 15 in four directions contact the inner wall of the pipeline to complete the support, so that the central square axis 1 coincides with the axis of the pipeline, thereby avoiding contact with the pipeline dirt below, and can be fixed on the pipeline robot to perform positioning light curing as the pipeline robot moves in the pipeline.

[0026] The end of the central square shaft 1 is coaxially connected to a motor 12; the motor 12 is fixedly connected to a fixed plate 17; when working, the central square shaft 1 can be driven to rotate by the motor 12, and then the driving plate 2 fixed on the central square shaft 1 can be driven to rotate, thereby achieving uniform rotation on the inner wall of the pipeline, so that each part of the pipeline can be exposed to uniform light time, so that the curing effect is uniform.

[0027] The central square shaft 1, driving plate 2, limiting plate 3, symmetrical swing arm 7, movable plate 8 and fixed plate 17 are all made of hard plastic.

[0028] The length of the symmetrical swing arm 7 is greater than the movable plate 8, and less than the spacing between the fixed plate 17 and the limiting plate 3; during operation, the clearance between the symmetrical swing arm 7 and the movable plate 8 allows the symmetrical swing arm 7 to be smoothly lifted up around the first nut pair 6 and fixed, and then the movable plate 8 is lifted up around the second nut pair 16 and fixed, so that the movable plate 8 and the ultraviolet lamp 11 can be adjusted to be parallel to the inner wall of the drainage pipe at any height and in close contact with the inner wall of the drainage pipe when the height is adjusted as the symmetrical swing arm 7 is lifted up, so as to achieve close-range curing, so that the curing time and curing distance can be determined, so that stable operation can be maintained when curing the inner walls of pipes of different diameters, solving the problem that the existing light curing device cannot change the distance from the inner wall of the pipe for curing.

[0029] By adopting the above scheme, when the utility model is used, it is first connected to the pipeline inspection robot, and then before entering the pipeline, the first nut pair 6 and the second nut pair 16 are rotated to change the angle between the symmetrical swing arm 7 and the movable plate 8 and the central square axis 1, so that the movable plate 8 and the ultraviolet lamp 11 are attached to the inner wall of the drainage pipe, so as to achieve close irradiation of the pipeline light-curing repair material for curing, so that under drainage pipes of different diameters, the same distance and the same time of curing can be achieved, so as to achieve the same curing effect, so that the effective curing time can be determined according to the repair area, and the problem that the existing light-curing device cannot adjust the distance between the light-curing repair material and the pipeline of different diameters to ensure the same curing effect is solved; the rollers 15 in four directions are contacted with the inner wall of the pipeline to complete the support, so that the central square axis 1 coincides with the axis of the pipeline, so that it can not contact the pipeline dirt below, and can be fixed on the pipeline robot, and the positioning light curing is performed as the pipeline robot moves in the pipeline; the central square axis 1 can be driven to rotate by the motor 12, thereby driving the fixed central square axis 1 to rotate. The driving plate 2 on the central square shaft 1 rotates to achieve uniform rotation on the inner wall of the pipe, so that each part of the pipe can be exposed to uniform light for a uniform time, so that the curing effect is uniform; the central square shaft 1, the driving plate 2, the limit plate 3, the symmetrical swing arm 7, the movable plate 8 and the fixed plate 17 made of hard plastic make it possible to drive and adjust the positions of the various parts with lower force requirements, so that it is more convenient to operate and move; through the clearance fit between the symmetrical swing arm 7 and the movable plate 8, the symmetrical swing arm 7 can be smoothly lifted up and fixed around the first nut pair 6, and then the movable plate 8 is lifted up and fixed around the second nut pair 16, so that the movable plate 8 and the ultraviolet lamp 11 can be adjusted to the inner wall of the drainage pipe at any height and in close contact with the inner wall of the drainage pipe when the height is adjusted as the symmetrical swing arm 7 is lifted, so as to achieve close-range curing, so that the curing time and curing distance can be determined, so that stable operation can be maintained when curing the inner walls of pipes of different diameters, solving the problem that the existing light curing device cannot change the distance from the inner wall of the pipe for curing.
