[0024] As Figures 4 to 7As shown, in another embodiment of the present utility model, a rotating ring 203 is installed on one side of the turntable 202 away from the rotating shaft 207. The rotating ring 203 is snap-fitted inside the movable slot 201. An external gear ring 204 is installed on the outside of the turntable 202. A gear 206 is installed at the output end of the motor 205. The gear 206 is meshed with the external gear ring 204. Second fixed rods 215 are respectively installed in the inner part of the guiding groove 208 located in the turntable 202. The rod bodies of the second fixed rods 215 respectively pass through and are movably installed inside the second push plates 216. A number of grooves 211 are respectively provided on the outside of the movable blocks 209. First fixed rods 212 are respectively installed inside the grooves 211. One ends of the first push plates 214 are respectively movably installed inside the grooves 211, and the rod bodies of the first fixed rods 212 respectively pass through and are movably installed inside the first push plates 214.

[0025] After the repair ring is initially connected to the pipeline through inflation, the user places the moving trolley 1 at one end of the repair ring, and then the user starts the cylinder 210 to pull the movable block 209, so that the movable block 209 squeezes the first push plate 214 along the guiding groove 208. Then, the first push plate 214 and the second push plate 216 can rotate around the first fixing rod 212, the second fixing rod 215 and the third fixing rod 217 respectively, so that the first push plate 214 and the second push plate 216 expand outwards, forming a triangle between the first push plate 214, the second push plate 216 and the rotating shaft 207. The second push plate 216 drives the scraping plate 225 and the movable roller 224 to fit against the inner wall of the repair ring respectively. Then, the moving trolley 1 can move inside the repair ring. At the same time, when moving, the motor 205 drives the gear 206 to rotate, and then the gear 206 can cooperate with the external gear ring 204 to control the turntable 202 and the rotating ring 203 to rotate, so that the turntable 202 drives the rotating shaft 207, the scraping plate 225 and the movable roller 224 to rotate, and the scraping plate 225 and the movable roller 224 evenly scrape and squeeze the inner wall of the repair ring, improving the tightness between the repair ring and the pipeline and the repair effect of the repair ring. Then, after the scraping plate 225 and the movable roller 224 scrape and squeeze the repair ring, the ultraviolet curing lamp 4 directly cures the repair ring, making the repair ring and the pipeline form an integral body, further improving the overall repair effect;

[0026] The rotary power supply device is a special power supply method used to provide electrical energy for rotating equipment, so that when the ultraviolet curing lamp 4 rotates following the rotating shaft 207, it can still stably supply power to the ultraviolet curing lamp 4, avoiding the situation of wire entanglement.

[0027] The working principle of this pipeline repair curing and shaping device:

[0028] In use, first, after the repair ring is initially connected to the pipeline through inflation, the user places the moving trolley 1 at one end of the repair ring. Then, the user starts the cylinder 210, which pulls the movable block 209, causing the movable block 209 to squeeze the first push plate 214 along the guiding groove 208. Then, the first push plate 214 and the second push plate 216 can rotate around the first fixing rod 212, the second fixing rod 215, and the third fixing rod 217 respectively, so that the first push plate 214 and the second push plate 216 expand outwards, forming a triangle between the first push plate 214, the second push plate 216, and the rotating shaft 207. The second push plate 216 drives the scraping plate 225 and the movable roller 224 to fit against the inner wall of the repair ring. Then, the moving trolley 1 can move inside the repair ring. Meanwhile, when moving, the motor 205 drives the gear 206 to rotate, and then the gear 206 can cooperate with the external gear ring 204 to control the rotation of the turntable 202 and the rotating ring 203, causing the turntable 202 to drive the rotating shaft 207, the scraping plate 225, and the movable roller 224 to rotate, so that the scraping plate 225 and the movable roller 224 evenly scrape and squeeze the inner wall of the repair ring, improving the tightness between the repair ring and the pipeline and enhancing the repair effect of the repair ring. After the scraping plate 225 and the movable roller 224 finish scraping and squeezing the repair ring, the ultraviolet curing lamp 4 directly cures the repair ring, making the repair ring and the pipeline form an integral body, further improving the overall repair effect.

[0029] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation modes of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation modes here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
