It is an integral part of the water supply and drainage system and plays an important role in the entire water supply and drainage system. When the pipeline is in use, multiple sections of pipelines are connected to form a drainage pipe of the required length; the connected pipeline is very long, and the water inside it will impact the inner wall of the pipeline multiple times, generating noise. Therefore, we have designed a water supply and drainage engineering pipeline connection device with less noise. Summary of the Invention

DETAILED DESCRIPTION

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0015] 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, with second flanges 8 at both ends of the outer tube 1 respectively, an inner tube 3 is sleeved inside the outer tube 1, one end of the inner tube 3 is provided with a first flange 2, and several connecting holes 4 are provided on the first flange 2 and the second flange 8. The other end of the inner tube 3 is sleeved with a rubber ring 7, 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 contacts and cooperates 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 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 impacted by water, it can provide cushioning and shock absorption, reducing the impact of falling, thereby reducing noise. The waterproof cloth 5 can also deform after being impacted, making it difficult for dirt to adhere to the surface. The middle part of the waterproof cloth 5 is stretched into a rectangle, so that the flow rate of water along the inner surface is smaller when passing through, further reducing noise. In addition, the hollow cavity 6 can also block the transmission of noise, which can meet practical needs and is suitable for promotion. When in use, according to the required length, the outer tube 1 of the corresponding number of sections is selected, and the inner tube 3 is respectively inserted into 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. The outer tube 1 is then connected with bolts, the first flange 2, and the second flange 8 to form a drainage pipe of the required length. When water enters the drainage pipe, it flows within the waterproof cloth 5. When the water flow impacts the waterproof cloth 5, the flexibility of the waterproof cloth 5 provides cushioning and shock absorption, 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 there will be enough space for the water to be discharged in time. When there is no more water flowing through, 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 hits the waterproof cloth 5, the waterproof cloth 5 is twisted and deformed, so that impurities attached to it fall off to avoid blockage.

[0016] Specifically, if Figure 1 As shown, the waterproof sheet 5 of this embodiment has vertical rods 20 fixedly mounted on either side. Drawstrings 21 are fixedly connected at each end of the vertical rods 20. Rings 22 corresponding to the drawstrings 21 are fixedly mounted on the inner tube 3. The drawstrings 21 pass through the corresponding rings 22 and are connected to the rings 22 via elastic members. When a large amount of water flows through the middle of the waterproof sheet 5, the water exerts a force on the sheet, causing it to expand and increase its cross-sectional area, thereby facilitating rapid drainage of the water. As the sheet 5 expands, it pulls on the vertical rods 20, which in turn pull on the drawstrings 21, accumulating potential energy within the elastic members.

[0017] Specifically, such as Figure 1 、 Figure 5 As shown, the elastic member of this embodiment includes a spring 30, which is mounted on a drawstring 21. 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. The movable plate 31 is slidably mounted on the circular ring 22. When water causes the middle portion of the waterproof cloth 5 to expand, the vertical rods 20 move closer to each other, thereby driving the drawstring 21 to move. The drawstring 21 then pulls the corresponding movable plate 31 along the axis of the circular ring 22, compressing the spring 30. When the water in the waterproof cloth 5 is drained, the spring 30, relying on its elastic force, drives the movable plate 31, the drawstring 21, and the vertical rods 20 to reset, thereby pulling the middle portion of the waterproof cloth 5 back into a rectangular shape.

[0018] Further, such as Figure 1 、 Figure 5 As shown, in this embodiment, slide rods 40 are fixedly mounted on either side of the circular ring 22. Corresponding slide holes 41 are defined in the movable plate 31, and the slide rods 40 are slidably engaged with the slide holes 41. When the pull cord 21 moves the movable plate 31, the movable plate 31 slides on the slide rods 40. The slide rods 40 guide the movement of the movable plate 31, making the spring 30 more stable when compressed.

[0019] Furthermore, Figure 1 As shown, in this embodiment, several guide ropes 50 are fixedly mounted on one end of the tarpaulin 5. After the two outer tubes 1 are connected, a portion of the guide ropes 50 enters the lower tarpaulin 5. The guide ropes 50 can guide the water in the upper tarpaulin 5 to flow to the lower tarpaulin 5, reducing the impact of water on the tarpaulin 5 and further reducing noise.

[0020] 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 various embodiments of the present invention.
