[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 The utility model provides a technical solution: a CIPP liner pipe that is easy to install, including a liner pipe body 1, a plurality of glue outlet holes connected to its inner cavity are arranged on the circumferential outer wall of the liner pipe body 1, a glue inlet pipe 3 connected to its inner cavity and in an L-shaped shape is fixed near the left end of the inner wall of the liner pipe body 1, a mounting ring 2 is slidably inserted near the left end of the inner wall of the liner pipe body 1, a rubber through pipe 4 slidably inserted with its horizontal pipe end is arranged on the left side of the rubber inlet pipe 3, a fixing ring 5 is coaxially fixed on the circumferential outer wall of the rubber through pipe 4, two mutually symmetrical connecting rods 6 are fixed between the fixing ring 5 and the inner wall of the mounting ring 2, and the left end face of the mounting ring 2 is located on the left side of the left end face of the liner pipe body 1, and also includes:

[0028] A plurality of guide mechanisms 9 are arranged on the circumferential outer wall of the mounting ring 2 and are located on the left side of the inner liner pipe body 1. The guide mechanisms 9 include a fixed tube 91 fixed on the circumferential outer wall of the mounting ring 2, a telescopic rod 92 slidably plugged with the fixed tube 91, a mounting plate 93 fixed on the surface of the telescopic rod 92 on the side away from the mounting ring 2, and a universal wheel 94 installed on the surface of the mounting plate 93 on the side away from the mounting ring 2. By arranging the mounting ring 2 and the plurality of guide mechanisms 9, the installation of the inner liner pipe body 1 can be guided. By arranging the fixing ring 5, two connecting rods 6, the glue inlet pipe 3 and the glue through pipe 4, it is convenient to introduce glue into the inner liner pipe body 1, thereby facilitating the installation of the inner liner pipe body 1. By connecting the external ropes with the two connecting rods 6, it is also convenient to disassemble the mounting ring 2, the glue through pipe 4, the fixing ring 5, the two connecting rods 6 and the plurality of guide mechanisms 9, thereby making the installation of the entire CIPP inner liner pipe more convenient.

[0029] In this embodiment, a mounting hole communicating with the inner cavity of the fixed cylinder 91 is provided on the side wall thereof, and the guide mechanism 9 further comprises a fastening screw 95 threadedly connected to the mounting hole on the outer wall of the fixed cylinder 91, and a side surface of the fastening screw 95 close to the telescopic rod 92 on the same side is in tight contact with the outer wall of the telescopic rod 92 on the same side, thereby facilitating the limiting of the plurality of telescopic rods 92 and the universal wheel 94.

[0030] In addition, two slots are provided on the inner wall of the liner tube body 1, and two plug-in blocks 10 are fixed on the circumferential outer wall of the mounting ring 2, which are slidably inserted into the slots on the same side of the inner wall of the liner tube body 1, so as to guide the disassembly and assembly of the mounting ring 2, and also facilitate the guidance of the insertion of the rubber hose 4 and the rubber inlet hose 3.

[0031] Furthermore, the diameter of the glue hole on the circumferential outer wall of the inner liner pipe body 1 is 10-20 mm, and a sealing ring is provided at the position where the glue inlet pipe 3 contacts the inner liner pipe body 1. In this article, the diameter of the glue hole on the circumferential outer wall of the inner liner pipe body 1 is preferably set to 12 mm, so that the sealing between the glue inlet pipe 3 and the inner liner pipe body 1 can be better to prevent leakage of glue.

[0032] Specifically, the plurality of guide mechanisms 9 on the outer wall of the mounting ring 2 are arranged in a ring shape with equal spacing, and the fixing tube 91 is welded and fixed to the mounting ring 2 , so that the guiding effect of the plurality of guide mechanisms 9 can be better.

[0033] It is worth noting that a traction rod 7 is fixed to the left surface of the connecting rod 6, and a tying rope ring 8 is fixed to the left surface of the traction rod 7. The external rope is connected to the two tying rope rings 8 to facilitate the disassembly of the mounting ring 2, the rubber hose 4, the fixing ring 5, the two connecting rods 6 and several guide mechanisms 9.

[0034] It is worth mentioning that the longitudinal cross-sectional shape of the slot on the inner wall of the liner tube body 1 is a convex shape, and the shape of the plug block 10 is a convex shape that matches the shape of the slot on the inner wall of the liner tube body 1, which can make the connection between the plug block 10 and the slot on the same side of the inner wall of the liner tube body 1 tighter, and thus indirectly make the connection between the mounting ring 2 and the liner tube body 1 tighter.

[0035] In the specific use process of this embodiment, when the liner pipe body 1 needs to be installed, the installation ring 2 is first plugged into the liner pipe body 1 through the two plug blocks 10 and the two slots on the inner wall of the liner pipe body 1. At this time, the rubber tube 4 is plugged into the horizontal pipe end of the rubber inlet pipe 3, and then the external rope is connected to the two rope rings 8, and the rubber supply hose of the external glue supply device is tightly sleeved with the rubber tube 4, and then several fastening screws 95 are loosened, and several universal wheels 94 are pulled. When the end of the universal wheel 94 away from the installation ring 2 is in the same plane with the circumferential outer wall of the liner pipe body 1, several fastening screws 95 are then tightened;

[0036] After the entire liner is placed inside the municipal pipeline, the entire liner can be driven to move by the water pressure inside the municipal pipeline. The liner body 1 moves under the guidance of the installation ring 2 and a plurality of guide mechanisms 9. When the liner body 1 moves to the position to be repaired, the external glue supply device is started. The external glue supply device transports the glue from its glue supply pipe to the inside of the glue pipe 4. The glue entering the glue pipe 4 then enters the liner body 1 through the glue inlet pipe 3. The glue entering the liner body 1 then flows out from a plurality of glue outlet holes on its circumferential outer wall to be distributed between its circumferential outer wall and the inner wall of the municipal pipeline, thereby fixing the liner body 1.

[0037] When the glue passing is completed, the external glue supply device is closed, and then the two rope rings 8 are pulled by the external rope. The movement of the rope rings 8 drives the traction rod 7 fixed thereto to move, and the movement of the traction rod 7 drives the connecting rod 6 fixed thereto to move. The movement of the two connecting rods 6 drives the movement of the mounting ring 2. The movement of the mounting ring 2 can separate the two plug blocks 10 from the two slots on the inner wall of the liner pipe body 1, and can also separate the glue passing pipe 4 from the glue inlet pipe 3, thereby completing the disassembly work.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
