Prevent municipal drainage pipe of stifled type

Technical Field

The application relates to municipal drainage pipe's technical field especially relates to a municipal drainage pipe who prevents stifled type.

Background

Municipal drainage pipelines include various drainage pipelines such as rainwater pipelines, domestic sewage pipelines, industrial sewage pipelines and the like, and the drainage pipelines are an important component in municipal construction and are an indispensable part for building urban infrastructures.

Municipal drainage pipelines are generally buried underground in cities, and communicate factories, residential buildings or roads with sewage treatment plants, so that wastewater discharged from the factories, the residential buildings or the roads can flow into the sewage treatment plants for treatment. Because distribute between each mill, the residential building relatively for the dispersion, municipal drainage pipe need communicate a plurality of mills or residential buildings that disperse in different places, therefore municipal drainage pipe generally has a plurality of return bends in order to change the flow direction of rivers in the pipeline for waste water rivers can gather in municipal drainage pipe's trunk.

In view of the above-mentioned related technologies, the inventor believes that waste water often contains many garbage impurities, and the garbage impurities are most likely to gather at the bent position of the municipal drainage pipeline and block the drainage pipeline, so that the drainage pipeline cannot normally discharge the waste water, and inconvenience is caused to the life of residents and the production of factories.

The utility model provides a municipal drainage pipe's that prevents stifled type theory of operation as follows:

when the drainage pipeline is unblocked: the sewage flows in from the inflow section 11 of the main flow pipe 1, changes the flow direction through the first bending pipe 12, and then flows out from the outflow section 13. At this time, since the second horizontal section 214 and the third horizontal section 222 of the auxiliary flow pipe 2 are both higher than the outflow section 13, the sewage is not shunted by the auxiliary flow pipe 2.

When the first bending pipe 12 is blocked: the sewage is accumulated in the inflow section 11, so that the sewage flows into the second horizontal section 214 from the inflow section 11, sequentially flows through the first vertical section 211, the second bending pipe 212, the first horizontal section 213, the second vertical section 221, the third horizontal section 222 and the third vertical section 223, and finally flows into the outflow section 13 again from the third vertical section 223, thereby realizing the automatic switching of the flow channel and effectively reducing the influence on the drainage pipeline caused by the blockage of the main flow pipe 1. At this moment, the municipal administration staff can detach the first closing plate 122 and clean up the rubbish debris in the main flow pipe 1, thereby dredging the main flow pipe 1. When the second bent pipe 212 is also blocked, the municipal administration staff can remove the second closing plate 2122 to clean up the garbage and sundries in the auxiliary flow pipe 2, so as to dredge the auxiliary flow pipe 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
