[0002] During water supply and drainage construction, a large number of pipes are required. During installation, some pipes are exposed to the elements. When exposed to warm, humid air, the resulting temperature difference causes moisture in the air to condense on the pipe walls, easily leading to rust. Therefore, anti-condensation structures are needed to prevent condensation. Existing anti-condensation structures for drainage pipes are complex, cumbersome to install, and impose a significant workload on workers, impacting installation efficiency. Utility Model Content

Multiple clamps are provided in the circumferential direction of the inner pipe, forming a circle that matches the water supply and drainage pipeline. Each clamp is connected to the first inner pipe by a telescopic rod, and each telescopic rod is provided with a spring. The first inner pipe, the second inner pipe, and the outer pipe are all semi-circular pipes. One end of the two semi-circular pipes of the first inner pipe, the second inner pipe, and the outer pipe are rotatably connected together by a fixing plate and a rotating shaft.

[0019] The first inner tube 1, the second inner tube 4, and the outer tube 12 are arranged concentrically, with the first inner tube 1 located at the innermost part. Both the first inner tube 1 and the second inner tube 4 are fixedly connected to the surface of the heat insulation pad 11, and the outer tube 12 is fixedly connected to the surface of the heat insulation pad 11. By setting the heat insulation pad 11 and the outer tube 12, the cold air is further isolated.

[0020] Sealing plates 17 are fixedly connected to both ends of the first inner pipe 1, the second inner pipe 4, and the outer pipe 12. The sealing plates 17 are made of rubber. The sealing plates 17 isolate the inside of the first inner pipe 1 and the second inner pipe 4 from the outside, thereby preventing water vapor from condensing on the surface of the drain pipe.

Under the action of telescopic rod 5 and spring 6, the first inner pipe 1 is separated from the drain pipe, reducing the transmission of cold air from the drain pipe to the first inner pipe 1 and the second inner pipe 4. Under the action of insulation pad 11 and outer pipe 12, the cold air is further isolated to prevent condensation on the surface of the first inner pipe 1 and the second inner pipe 4. Under the action of sealing plate 17, the inside of the first inner pipe 1 and the second inner pipe 4 is isolated from the outside, preventing water vapor from condensing on the surface of the drain pipe.
