[0002] Municipal pipelines refer to the pipeline systems used for drainage in cities, and are an important part of urban infrastructure. The bending structure of municipal pipelines usually refers to the bends, corners and other structures in the pipeline system. These structures may affect the fluidity, pressure distribution, cleaning and maintenance of the pipeline. They are mainly used to change the direction of the pipeline to adapt to the posture and design requirements. The bending angle of the pipeline is usually designed according to the needs of the specific project. Common bending angles include 45-degree elbows and 90-degree elbows.
[0003] After searching, a Chinese patent with the announcement number of CN220453051U discloses a municipal pipeline bending structure. The patent records that a chlorinated rubber anti-corrosion paint layer is fixedly connected to the inside of a high-strength stainless steel sleeve, a protective sleeve is provided on the surface of the PE pipe, a spring is fixedly connected to the surface of the PE pipe, and the side of the spring away from the PE pipe is fixedly connected to the inside of the protective sleeve. An arc plate is fixedly connected to the top of the right side of the PE pipe to prevent the water flow from directly impacting the bend of the PE pipe, and then the spring is used to buffer and protect the surface of the bend of the PE pipe through the protective sleeve, so as to achieve the advantages of good impact resistance, and the water flow is not easy to directly impact the bend of the municipal pipe, and the bend is not easy to be corroded and damaged, which is convenient for users to use the technical solution;

The pipe body 1 serves as the main body of the entire structure and bears the pressure of the fluid in the pipeline. Both ends of the pipe body 1 are fixedly connected with connecting rings 2. The connecting ring 2 and the flange 3. The connecting ring 2 is fixed at the end point of the pipe body 1, and the flange 3 is fixed at one end of the connecting ring 2. Their function is to connect different parts of the pipeline to ensure the support of the structure. One side of the connecting ring 2 is fixedly connected with the flange 3. The interior of the flange 3 is provided with a mounting hole 4. The mounting hole 4 is located inside the flange 3 and is used to install the entire bending structure into the pipeline system. The annular distribution of the mounting holes 4 can provide a variety of installation options to ensure flexible and stable installation. The interior of the pipe body 1 is rotatably connected with a rotating shaft 8, and the outer side wall of the rotating shaft 8 is fixedly connected with a fixing rod 9 A brush is fixedly connected to the outside of the fixing rod 9. The brush is fixed on the fixing rod 9 to clean the inside of the pipe or provide a guiding effect to ensure that the fluid does not stop flowing at the bend. A fluorocarbon paint layer 7 is arranged inside the pipe body 1, and a polyurethane layer 6 is arranged on one side of the fluorocarbon paint layer 7. A PVC layer 5 is arranged on the right side of the polyurethane layer 6. The fluorocarbon paint layer 7, the polyurethane layer 6 and the PVC layer 5 are located inside the pipe body 1 to provide protection and anti-corrosion functions for the fluid in the pipe. The fluorocarbon paint layer 7, as the innermost layer, provides resistance to chemical corrosion, and the polyurethane layer 6 and the PVC layer 5 provide protection against physical damage and enhance the structural strength of the pipe. A sealing ring is provided inside the flange 3. The sealing ring is located inside the flange 3 to ensure that the joint of the pipe is sealed to prevent fluid leakage.
[0026] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the thickness of the polyurethane layer 6 is 3 mm, the thickness of the fluorocarbon paint layer 7 is 5 mm, the thickness of the PVC layer 5 is 2 mm, the fixing rods 9 are distributed in a circular array, the brush is made of stainless steel, the mounting holes 4 are distributed in a circular array, and the shape of the mounting holes 4 is a circular through hole. The thicknesses of the polyurethane layer 6, the fluorocarbon paint layer and the PVC layer are adjusted in order to better adapt to specific environmental conditions or improve the stability of the structure. The thickness of the polyurethane layer 6 is increased to 3 mm, the fluorocarbon paint layer 7 is increased to 5 mm, and the thickness of the PVC layer is reduced to 2 mm.

When water flows through the pipeline, the design of the rotating shaft 8 and the fixing rod 9 enables the power of the water flow to drive the rotation of the fixing rod 9, thereby driving the rotation of the brush. This mechanical structure can ensure the regularity of the inner wall of the pipeline, prevent the accumulation of scale, maintain the internal smoothness and cleanliness of the pipeline, and ensure the flow of water flow. The combination of the fluorocarbon paint layer 7, the polyurethane layer 6 and the PVC layer 5 provides all-round protection, which can not only resist chemical corrosion, but also enhance the structural strength of the pipeline and prevent the external environment from physically affecting the pipeline. Such a protective layer structure extends the service life of the pipeline, reduces costs, and ensures the reliability and stability of the pipeline system. The sealing ring is located inside the flange 3 to ensure the sealing of the pipeline connection and prevent fluid leakage.
