Technical Field

[0001] The utility model relates to the field of municipal pipelines, in particular to a novel municipal drainage pipeline connection structure. Background Art

[0002] Municipal drainage pipes are an important part of the urban drainage system, mainly used to collect, transport and discharge rainwater, sewage and wastewater in the city. It is crucial to the ecological environment and sustainable development of the city. It can solve the basic problems of domestic sewage, rainy rainwater deposition and industrial wastewater in the city, ensure the normal passage of citizens and provide citizens with a healthy living environment. The connection structure of municipal drainage pipes affects the normal operation of the pipes.

[0003] When the water volume in municipal drainage pipes suddenly increases, they will be under tremendous pressure and produce vibrations. The pipe joints are relatively fragile, and the vibrations will cause them to loosen. Utility Model Content

[0004] The purpose of the utility model is to provide a novel municipal drainage pipe connection structure to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of municipal drainage pipe connection structure, including a pipe, a flange sleeve, a flange, a flange gasket, a limiting hole, a slide groove, and an oscillating pressure dividing structure. The front and rear inner end interfaces of the pipes are respectively connected to the flange sleeves, and the two flanges are respectively installed on the inner ends of the flange sleeves. The flange gasket is sealed at the pipe interface through the front and rear flanges. The limiting hole is axially opened on the upper part of the flange and the flange gasket, and the slide groove is opened on the upper part of the side end of the flange and the flange gasket through the limiting hole, and the oscillating pressure dividing structure is installed on the slide groove through the pipe.

[0006] On the basis of the above technical scheme, the oscillation pressure-dividing structure includes a support beam, a fixing bolt, a support plate, a threaded hole A, a limiting block, a support column, a threaded hole B, and a fixing tube. The support beam is provided with fixing bolts, a threaded hole A is opened at the top of the support plate, and the bottom of the support plate is slidably connected to the slide groove, and the fixing bolt is fixed to the support plate in the middle of the support beam through the threaded hole A, the limiting block is fixed to the bottom end of the support plate, and the limiting block corresponds to the limiting hole, a threaded hole B is opened at the top of the support column, and the threaded hole B is fixed to the support column at the front and rear parts of the support beam, the side end of the fixing tube is fixed to the bottom end of the support column, and the fixing tube is respectively fixed to the side ends of the front and rear pipes.

[0007] Based on the above technical solution, the flange transmits the vibration at the interface to the front and rear pipelines through the vibration pressure distribution structure.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model opens a limiting hole in the flange-connected pipeline connection structure for installing an oscillation pressure-dividing structure, which forms contact with the side end of the pipeline, thereby dispersing the force exerted on the pipeline connection to the entire pipeline when the pipeline oscillates, thereby reducing the occurrence of looseness.

DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a new type of municipal drainage pipe connection structure includes a pipe 1, a flange sleeve 2, a flange 3, a flange gasket 4, a limiting hole 5, a slide groove 6, and an oscillating pressure dividing structure 7. The front and rear inner end interfaces of the pipes 1 are respectively connected to the flange sleeve 2, and the two flanges 3 are respectively installed on the inner ends of the flange sleeve 2. The flange gasket 4 is blocked at the interface of the pipe 1 through the front and rear flanges 3. The limiting hole 5 is axially opened on the upper part of the flange 3 and the flange gasket 4. The slide groove 6 is opened on the upper part of the side ends of the flange 3 and the flange gasket 4 through the limiting hole 5. The oscillating pressure dividing structure 7 is installed on the slide groove 6 through the pipe 1.

[0015] The oscillating pressure-dividing structure 7 includes a support beam 8, a fixing bolt 9, a support plate 10, a threaded hole A11, a limit block 12, a support column 13, a threaded hole B14, and a fixing tube 15. The support beam 8 is provided with fixing bolts 9. The top of the support plate 10 is provided with a threaded hole A11, and the bottom of the support plate 10 is slidably connected to the slide groove 6, and the fixing bolt 9 is fixed to the support plate 10 at the middle of the support beam 12 through the threaded hole A11. The limit block 12 is fixed to the bottom of the support plate 10, and the limit block 12 corresponds to the limit hole 5. The top of the support column 13 is provided with a threaded hole B14, and the threaded hole B14 is fixed to the support column 13 at the front and rear parts of the support beam 12. The side end of the fixing tube 15 is fixed to the bottom end of the support column 13, and the fixing tube 15 is respectively fixed to the side ends of the front and rear pipes 1.

[0016] The flange 3 transmits the vibration at the interface to the front and rear pipes 1 through the vibration pressure distribution structure 7.

[0017] The working principle of the utility model is as follows: when the water flow in the pipeline 1 suddenly increases, the pressure becomes larger, and the pipeline 1 vibrates. When the vibration is transmitted to the connection of the flange 3, the flange 3 transmits the force through the support plate 10 to the support beam 8 through the limit block 12. The support beam 8 transmits the vibration force to the fixed cylinder 5 through the support column 13. The fixed cylinder 5 transmits the vibration to the pipeline 1, so that the force on the interface of the pipeline 1 is shared, reducing the influence of the vibration force on the flange interface and reducing the occurrence of looseness.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
