[0007] The right end of the small-diameter pipe expands outward to the same inner diameter as the large-diameter pipe.

[0008] Beneficial effects of the utility model:

[0009] The utility model is equipped with a silt discharge pipe, which can open the cap of the silt discharge pipe when the drainage pipe is blocked and use water pressure to quickly discharge the silt, thereby effectively solving the blockage problem and ensuring the normal operation of the drainage system. The two silt discharge pipes are provided to increase the flexibility and efficiency of silt discharge. A screen is provided in the large-diameter connecting pipe, which can effectively intercept larger impurities and particulate matter entering the drainage pipe and prevent them from entering the drainage system and causing deeper blockage, thereby extending the service life of the drainage system.

[0016] like Figure 1-5 As shown: a variable diameter PE drainage pipe connecting pipe, including a large-diameter pipe 1 and a small-diameter pipe 2; the small-diameter pipe 2 is located at the left end of the large-diameter pipe 1, the small-diameter pipe 2 is fixedly connected to the large-diameter pipe 1, and the inner side walls of the opposite ends of the large-diameter pipe 1 and the small-diameter pipe 2 are provided with mounting threads 8, the top and bottom left ends of the outer wall of the large-diameter pipe 1 are fixedly connected with a silt discharge pipe 3, and the outer wall of the pipe mouth of the silt discharge pipe 3 is threadedly connected with a cap 4, and a protrusion 9 is provided around the left end of the inner wall of the large-diameter pipe 1, and the protrusion 9 is in a closed shape. The inner wall of the left end of the large-diameter pipe 1 is provided with a screen 5, the edge of the screen 5 is in contact with the protrusion 9, and the edge of the screen 5 is provided with a plurality of evenly distributed fixing bolts 6, the fixing bolts 6 pass through the screen 5 and the protrusion 9, the fixing bolts 6 are threadedly connected with the protrusion 9, the fixing bolts 6 are slidably matched with the screen 5, and the screen 5 is located on the left side of the silt discharge pipe 3.

[0017] The upper outer wall of the pipe opening of the sludge discharge pipe 3 is provided with a sealing ring 7 , and the sealing ring 7 is located at the bottom of the inner wall of the cap plug 4 .

[0018] The right end of the small-diameter pipe 2 is expanded outward to be the same as the inner diameter of the large-diameter pipe 1.

[0019] PE pipes of different diameters are connected through the installation threads 8 of the large-diameter pipe 1 and the small-diameter pipe 2. When there is no blockage or the blockage is not serious, water flows in through the large-diameter pipe 1, is filtered by the screen 5, enters the small-diameter pipe 2, and then is discharged. The design of the screen 5 can effectively intercept larger impurities and particles to prevent them from entering the drainage system and causing deeper blockage;

[0020] Treatment of minor blockage: When there are many impurities accumulated on the outer wall of the screen 5 but no serious blockage has been caused, the operator can selectively open the cap 4 of one of the silt discharge pipes 3 (usually the lower silt discharge pipe, so as to use gravity to help silt discharge). Under the action of water pressure, the silt accumulated on the outside of the screen 5 will be flushed into the silt discharge pipe 3 and discharged with the water flow, thereby cleaning the screen 5.

[0021] Severe blockage treatment: If the screen 5 is severely blocked and affects normal drainage, the operator can open the caps 4 of the two silt discharge pipes 3 at the same time to increase the flow rate and speed of silt discharge and more effectively remove the blockage, or use tools to dredge;

[0022] Closing of the silt discharge pipe: After the silt discharge is completed, the operator needs to re-tighten the cap plug 4 on the pipe mouth of the silt discharge pipe 3 to ensure the sealing performance and prevent water leakage.
