[0022] Embodiment: A reinforcement structure at the joint of a municipal water supply pipeline, as Figure 1 - Figure 4 shown, including a receiving pipe 1. The receiving pipe 1 is a hollow pipe with openings at both ends. One end of the outer side of the receiving pipe 1 is provided with an inserting pipe 2. The inserting pipe 2 is a hollow pipe with openings at both ends. The diameter of the inserting pipe 2 is smaller than that of the receiving pipe 1. One end of the inserting pipe 2 can be inserted into the inside of the receiving pipe 1. An installation groove 3 is provided at the inner port of the receiving pipe 1. The installation groove 3 is an annular groove. A sealing ring 4 is arranged inside the installation groove 3. The sealing ring 4 is an annular soft rubber ring. The sealing ring 4 is installed inside the installation groove 3. The outer side of the sealing ring 4 is fixedly connected with the receiving pipe 1. During installation, first install the sealing ring 4 inside the installation groove 3, fixedly bond the outer side of the sealing ring 4 with the receiving pipe 1, and then insert one end of the inserting pipe 2 into the inside of the receiving pipe 1. The sealing ring 4 can improve the connection tightness between the receiving pipe 1 and the inserting pipe 2. One end of the outer side of the receiving pipe 1 close to the inserting pipe 2 is provided with a reinforcement mechanism 5. The reinforcement mechanism 5 is sleeved on the outer side of the receiving pipe 1. The inner side of the reinforcement mechanism 5 is fixedly connected with the receiving pipe 1. The reinforcement mechanism 5 can seal the joint between the receiving pipe 1 and the inserting pipe 2 and improve the stability of the pipeline joint.

[0023] Furthermore, the reinforcement mechanism 5 includes a fixing ring 6. The cross-section of the fixing ring 6 is an L-shaped rigid ring. The fixing ring 6 is sleeved outside the receiving pipe 1. One end of the fixing ring 6 is fixedly connected to the receiving pipe 1. Two groups of clamping plates 7 are arranged at the position inside the fixing ring 6 corresponding to the pipe connection. The two groups of clamping plates 7 are symmetrically installed inside the fixing ring 6. The clamping plate 7 is a C-shaped arc-shaped rigid strip. The opening of the clamping plate 7 faces the pipe. The arc curvature of the clamping plate 7 is the same as that of the pipe. The surface of the clamping plate 7 is designed in a Z-shaped step shape. The Z-shaped design of the clamping plate 7 can improve the reinforcement and fitting effect of the clamping plate 7. An adjusting rod 8 is arranged at the upper end of the fixing ring 6. The adjusting rod 8 is threadedly connected to the fixing ring 6. The lower end of the adjusting rod 8 passes through the fixing ring 6 and is movably connected to the clamping plate 7. Two groups of limiting bars 9 are arranged at the lower end of the clamping plate 7. The limiting bars 9 are C-shaped arc-shaped bars. The two groups of limiting bars 9 are symmetrically installed on both sides of the lower end of the clamping plate 7. The upper end of the limiting bar 9 is fixedly connected to the clamping plate 7. A sealing airbag strip 10 is arranged at the lower end of the clamping plate 7. The sealing airbag strip 10 is an annular soft rubber bladder. A storage cavity for reserved gas is arranged inside the sealing airbag strip 10. The outer shape of the sealing airbag strip 10 is designed in a Z-shaped step shape. The upper end of the sealing airbag strip 10 is fixedly connected to the clamping plate 7. An inflation nozzle 11 is arranged at one end of the outer side of the fixing ring 6. The inflation nozzle 11 is fixedly connected to the fixing ring 6. One end of the inflation nozzle 11 passes through the limiting bar 9 and extends to the lower end of the clamping plate 7. A connecting hose 12 is arranged at one end of the sealing airbag strip 10 relative to the inflation nozzle 11. The connecting hose 12 is an elastic rubber hose. One end of the connecting hose 12 is fixedly connected to the sealing airbag strip 10. The other end of the connecting hose 12 is fixedly connected to the inflation nozzle 11. During use, an air pump can be used to fill compressed air into the storage cavity inside the sealing airbag strip 10 through the inflation nozzle 11 and the connecting hose 12. A sealing cover 13 is arranged at the outer end of the inflation nozzle 11. One end of the sealing cover 13 is threadedly connected to the inflation nozzle 11. The sealing cover 13 can seal the inflation nozzle 11 to prevent the gas inside the sealing airbag strip 10 from leaking. A sealing component is arranged at the lower end of the sealing airbag strip 10. One end of the sealing component is connected to the sealing airbag strip 10.

[0024] Furthermore, the sealing component includes a sealing gasket 14. The sealing gasket 14 is an annular soft wear-resistant rubber gasket. The sealing gasket 14 is bent in a Z-shaped step shape. The lower end of the sealing gasket 14 is attached to the receiving pipe 1 and the inserting pipe 2. The upper end of the sealing gasket 14 is fixedly bonded to the sealing airbag strip 10. A filling groove is arranged inside the sealing gasket 14. A sealing gel 15 is filled in the inner groove of the sealing gasket 14. The sealing gel 15 is a gel-like pipe sealant. A glue outlet 16 is arranged at one end of the sealing gasket 14 close to the pipe. The glue outlet 16 is a circular through hole. The glue outlet 16 is communicated with the filling groove inside the sealing gasket 14. When the sealing gasket 14 is squeezed, the sealing gel 15 filled inside the sealing gasket 14 can be discharged through the glue outlet 16.

[0025] It should be noted that the present utility model is a reinforcement structure at the connection of a municipal water supply pipeline. During assembly, first, the receiving pipe 1 is hoisted and placed inside the pre-buried trench, then the sealing ring 4 is installed inside the installation groove 3, and then the inserted pipe 2 is hoisted and placed inside the pre-buried trench, so that one end of the inserted pipe 2 is inserted into the receiving pipe 1 to complete the connection. Then, by rotating the adjusting rod 8, the adjusting rod 8 pushes the clamping plate 7 downward during rotation. During the downward movement of the clamping plate 7, it pushes the sealing assembly into contact with the pipeline connection. Then, the sealing cover 13 is removed, and an external pump body is connected to the inflation nozzle 11. Compressed air is filled into the sealing airbag strip 10 through the inflation nozzle 11. After the sealing airbag strip 10 is inflated, it will squeeze the sealing gel 15 inside the sealing pad 14, and it flows out through the glue outlet 16, and then the gap at the pipeline connection is sealed. When the pressure inside the sealing airbag strip 10 is increased to the predetermined pressure, the sealing cover 13 is installed outside the inflation nozzle 11 to seal the inflation nozzle 11. By providing the reinforcement mechanism 5, the pipeline connection can be sealed after the water supply pipeline is connected, which can effectively improve the sealing effect at the pipeline connection, avoid leakage at the pipeline connection, and avoid waste of water resources. By providing a sealing assembly at the lower end of the sealing airbag strip 10, the sealing gel 15 inside the sealing assembly can seal the pipeline connection and can perform secondary sealing on the pipeline to improve the sealing effect.
