When laying municipal water supply and drainage pipelines, there are often a variety of pipe materials to choose from, and the connection methods are also different. At this time, a pipe connection structure is needed to connect the two sets of pipes. Seamless steel pipes, non-ferrous metals and stainless steel pipes are mostly welded and flanged; cast iron pipes are mostly socket-connected, and a few are flanged; plastic pipes are mostly threaded, bonded and hot-melt connected, etc. There are many other forms of non-metallic pipe connections.

[0003] The existing pipe connection structure becomes unstable after long-term use, resulting in breakage and leakage. At the same time, impurities inside the pipe can easily cause pipe blockage. Therefore, a municipal water supply and drainage pipe connection structure is needed. Utility Model Content

A municipal water supply and drainage pipe connection structure, through the coordinated use of a water inlet pipe, a sealing ring, a fastening ring, a bolt and a connecting pipe, during the use of the device, the water inlet pipe and the connecting pipe are respectively fitted with the two sides of the sealing ring, and then the fastening ring is set outside the water inlet pipe and the connecting pipe, and the bolts are tightened to tightly clamp the water inlet pipe, the sealing ring, the fastening ring and the connecting pipe together, thereby improving the firmness of the pipe connection, so that the pipe connection will not fall off after long-term use, and the service life of the connection structure is improved. The installation of the sealing ring ensures that there will be no water leakage, reduces the number of repairs of municipal water supply and drainage pipes, and reduces government expenses;

[0013] 2. A municipal water supply and drainage pipe connection structure is provided with a water inlet pipe, a hydraulic cylinder, a hydraulic rod, a blocking block, a filter screen, a roller bearing, a propeller and a brush. During the use of the device, impurities in the water are filtered out by the filter screen fixed in the connecting pipe, so that the outflowing water is cleaner. When the filter screen needs to be cleaned, the blocking block is lifted by the hydraulic cylinder fixed inside the connecting pipe. The force brought by the water flowing from the water inlet pipe to the connecting pipe causes the propeller installed on one side of the filter screen to rotate through the roller bearing. The rotation of the propeller drives the brush fixed on the other side of the propeller to rotate to clean the filter screen, thereby avoiding clogging of the filter screen due to long-term use, making the cleaning of the filter screen more convenient and reducing the cost of cleaning municipal water supply and drainage pipes.

[0014] 3. A municipal water supply and drainage pipe connection structure, which is used in conjunction with a water inlet pipe, a connecting pipe, a first fixing frame, a first water stop valve, a first pin, a sewage pipe, a second fixing frame, a second water stop valve and a second pin. During the cleaning process of the device, the first pin is pulled out, and the first water stop valve installed in the water inlet pipe is rotated to a closed state to prevent water from flowing. The first water stop valve is fixed by the first pin, and the second pin is pulled out, and the second water stop valve is rotated to an open state. The second pin is inserted to fix it, so that water and impurities in the connecting pipe flow out through the sewage pipe under the action of gravity, thereby improving the cleaning efficiency of the connecting structure and reducing the labor cost and time cost of disassembling the municipal water supply and drainage pipe connection structure for cleaning.
