DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] A water supply and drainage engineering pipeline connection device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, it includes an outer tube 1, and second flanges 8 are respectively provided at both ends of the outer tube 1. An inner tube 3 is sleeved in the outer tube 1, and a first flange 2 is provided at one end of the inner tube 3. The first flange 2 and the second flange 8 are provided with a plurality of connecting holes 4. A rubber ring 7 is sleeved at the other end of the inner tube 3, and the inner periphery of the rubber ring 7 is fixedly connected to the outer wall of the inner tube 3. The outer periphery of the rubber ring 7 is in contact with the inner wall of the outer tube 1, and a hollow cavity 6 is formed between the rubber ring 7, the inner tube 3 and the outer tube 1. A waterproof cloth 5 is fixedly installed in the inner tube 3, and the waterproof cloth 5 is cylindrical. The two ends of the waterproof cloth 5 are respectively fixedly connected to the inner wall of the inner tube 3, and the middle part of the waterproof cloth 5 is tightened. The present invention has a simple structure and an ingenious design. The waterproof cloth 5 has the flexibility of cloth. When it is impacted by water, it can buffer and reduce shock, reduce the impact when falling, and thus reduce noise. The waterproof cloth 5 can be deformed after being impacted, and dirt is not easy to adhere to the surface. The middle part of the waterproof cloth 5 is tightened into a rectangle, so that the flow rate of water flowing along the inner surface when passing through is smaller, further reducing noise. In addition, the hollow cavity 6 can also block the transmission of noise, which can meet actual needs and is suitable for promotion. When in use, according to the length requirements, select the outer tube 1 of the corresponding number of sections, and respectively set the inner tube 3 in the outer tube 1, so that the connecting hole 4 on the first flange 2 is aligned with the connecting hole 4 on the second flange 8, and then connect the outer tube 1 through bolts, the first flange 2, and the second flange 8 to assemble a drainage pipe of the required length. After water enters the drainage pipe, the water flows in the waterproof cloth 5. When the water flow impacts the waterproof cloth 5, the flexibility of the waterproof cloth 5 buffers and reduces shock, reducing the generation of noise. When the water flow is not large, the middle part of the waterproof cloth 5 remains rectangular, and the water flows along the inner wall of the waterproof cloth 5. The flow speed is smaller and the noise is smaller. When the water flow is large, the water will stretch the middle part of the waterproof cloth 5, the cross-sectional area will be expanded, and the water will have enough space to be discharged in time. When there is no more water flowing, the middle part of the waterproof cloth 5 will be restored again; in addition, compared with the direct contact between the inner tube 3 and the outer tube 1, the hollow cavity 6 between the rubber ring 7, the outer tube 1 and the inner tube 3 is not conducive to the propagation of sound, thereby further blocking the transmission of noise and further reducing noise; when water impacts the waterproof cloth 5, the waterproof cloth 5 is twisted and deformed, so that impurities attached to it fall off to avoid blockage.

[0015] Specifically, if Figure 1 As shown, the two sides of the waterproof cloth 5 described in this embodiment are respectively fixed with vertical rods 20, and the two ends of the vertical rods 20 are respectively fixedly connected with drawstrings 21, and the inner tube 3 is fixedly installed with a circular ring 22 corresponding to the drawstrings 21, and the drawstrings 21 pass through the corresponding circular rings 22 and are connected to the circular rings 22 through elastic members. When a large amount of water passes through the middle part of the waterproof cloth 5, the water gives a thrust to the waterproof cloth 5, causing the middle part to expand and increase the cross-sectional area, thereby facilitating the rapid discharge of water. When the waterproof cloth 5 expands, the waterproof cloth 5 pulls the vertical rods 20 to move, and the vertical rods 20 then pull the drawstrings 21, and the elastic members accumulate potential energy.

[0016] Specifically, Figure 1 , Figure 5 As shown, the elastic member of this embodiment includes a spring 30, which is sleeved on the drawstring 21, and a movable plate 31 is fixedly mounted on the spring 30, one end of the spring 30 is fixedly connected to the movable plate 31, and the other end of the spring 30 is fixedly connected to the circular ring 22, and the movable plate 31 is slidably mounted on the circular ring 22. When water expands the middle part of the waterproof cloth 5, the vertical rods 20 approach each other, thereby driving the drawstring 21 to move, and the drawstring 21 then pulls the corresponding movable plate 31 to move along the axis of the circular ring 22, and the spring 30 is compressed. When the water in the waterproof cloth 5 is discharged, the spring 30 drives the movable plate 31, the drawstring 21, and the vertical rod 20 to reset by elastic force, so that the middle part of the waterproof cloth 5 is pulled into a rectangle again.

[0017] Further, such as Figure 1 , Figure 5 As shown, the slide bars 40 are fixedly installed on both sides of the circular ring 22 of this embodiment, and the corresponding slide holes 41 are provided on the movable plate 31, and the slide bars 40 are slidably connected with the slide holes 41. When the pull rope 21 drives the movable plate 31 to move, the movable plate 31 slides on the slide bars 40, and the slide bars 40 guide the movement of the movable plate 31, so that the spring 30 is more stable when compressed.

[0018] Furthermore, Figure 1 As shown, a plurality of guide ropes 50 are fixedly installed at one end of the waterproof cloth 5 in this embodiment. After the two outer tubes 1 are connected, a part of the guide rope 50 enters the next waterproof cloth 5, and the guide rope 50 can guide the water in the previous waterproof cloth 5 to flow to the next waterproof cloth 5, thereby reducing the impact of water on the waterproof cloth 5 and further reducing noise.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
