[0023] Reference Figures 1-3 This utility model provides an embodiment of a rapid repair device for municipal public works pipelines, comprising two mutually cooperating semi-circular tubes 1. A rotating plate 2 is fixedly connected to the right end of each semi-circular tube 1. A connecting plate 3 is rotatably connected to the inner side of the rotating plate 2. Multiple sealing rings 4 are installed at the upper and lower ends of the inner side of each semi-circular tube 1 to improve the device's sealing performance. Multiple glue injection tubes 5 for injecting glue are fixedly connected to the upper and lower ends of the front semi-circular tube 1. A sealing cap 6 is threaded to the front end of each glue injection tube 5. Arc-shaped grooves 7 are provided at both the left and right ends of each semi-circular tube 1. Glue rods 8 are provided inside the arc-shaped grooves 7. A fixing plate 9 is fixedly connected to the outer side of the left end of each semi-circular tube 1. Bolt holes 10 are provided at both the upper and lower ends of the fixing plate 9. Fixing bolts 11 for fixing are inserted into the bolt holes 10. Reinforcing rings 18 are fixedly connected to the outer sides of both the upper and lower ends of each semi-circular tube 1. Reinforcing rods 19 are fixedly connected to the opposite side of each reinforcing ring 18.
[0024] The two semicircular tubes 1 are connected by a rotating plate 2 and a connecting plate 3, allowing for flexible opening and closing. During repair, the device is unfolded, installed on the outside of the pipe, and the two semicircular tubes 1 are closed. When closed, the rubber rod 8 is placed in the arc-shaped groove 7. The rubber rod 8 is used to improve the sealing of the connection of the other semicircular tube 1. Then, the fixing bolt 11 is inserted into the bolt hole 10 to fix the semicircular tube 1, so that the sealing ring 4 is tightly attached to the outer wall of the pipe, completing the installation of the device. Then, the sealing cap 6 is removed, and glue is injected into the inside of the device through the glue injection tube 5 to fill the gap between the two sealing rings 4, thereby filling the gap between the device and the pipe. After the glue solidifies, it further improves the sealing of the device.
[0025] Reference Figures 2-4The top of the semi-circular tube 1 is fixedly connected to a first connecting ring 12, and a slot 13 is provided on the outer side of the first connecting ring 12. The bottom of the semi-circular tube 1 is fixedly connected to a second connecting tube 14 for cooperating with the first connecting ring 12. The outer side of the second connecting tube 14 is provided with a retaining strip 20 for embedding into the interior of the second connecting tube 14. Sealing gaskets 15 are provided on both the front and rear sides of the upper inner wall of the semi-circular tube 1. The left and right ends of the rear sealing gasket 15 are provided with first splicing joints 16, and the left and right ends of the front sealing gasket 15 are provided with second splicing joints 17 for cooperating with the first splicing joints 16.
[0026] The first connecting ring 12 at the top of the semicircular tube 1 and the second connecting tube 14 at the bottom can be connected vertically to multiple repair devices through the cooperation of the slot 13 and the clip 20, which is convenient for use in long-distance pipeline repair. At the same time, the reinforcing rings 18 and reinforcing rods 19 on the outside of the upper and lower ends of the semicircular tube 1 enhance the overall structural strength of the device, enabling it to withstand a certain pressure during the repair process. The sealing gasket 15 on the inner wall of the upper end of the semicircular tube 1 can be spliced through the cooperation of the first splice 16 and the second splice 17, ensuring the sealing of the device connection and preventing liquid or gas leakage.
[0027] Working principle: During repair, the device is unfolded and then installed on the outside of the pipe, closing the two semi-circular tubes 1. When closed, the rubber rod 8 is placed into the arc-shaped groove 7, and then the fixing bolt 11 is inserted into the bolt hole 10 to fix the semi-circular tubes 1, ensuring the sealing ring 4 is tightly against the outer wall of the pipe. This completes the installation. The sealing cap 6 is then removed, and glue is injected into the inside of the device through the glue injection tube 5 to fill the gap between the two sealing rings 4, thus filling the gap between the device and the pipe. After the glue solidifies, it further improves the sealing performance of the device. When repairing a long pipe, multiple repair devices may be needed. In use, when installing the first device, the sealing gasket 15 is installed on the upper end of the semi-circular tube 1, so that it contacts the sealing ring 4 on the upper end of the inner wall of the semi-circular tube 1. When the first device is installed, the sealing gasket 15 is fixed to the outside of the pipe, with the upper end of the sealing gasket 15 exposed. The second device is installed on the outside of the pipe, so that the second connecting pipe 14 at the lower end of the second device cooperates with the first connecting ring 12 at the upper end of the first device, so that the two devices are connected for use. The second device presses the upper end of the sealing gasket 15 against the outside of the pipe. The sealing gasket 15 is used to improve the sealing at the connection between the two devices.
