[0040] The core pipe 1 is provided with guide vanes 11 for preventing the deposition of dirt in the core pipe 1, the guide vanes 11 are arranged in a spiral shape in the core pipe 1, and the guide vanes 11 guide the water flow in the core pipe 1 to flow along the guide vanes 11;
[0041] The sound attenuation pipe 3 comprises a pipe frame 31, the pipe frame 31 is provided with sound attenuation bodies 32, and the sound attenuation bodies 32 are uniformly distributed on the pipe frame 31;
[0042] The protective pipe 2 comprises an inner pipe 21, and a protective rib 22 is arranged outside the inner pipe 21, the protective rib 22 is uniformly distributed on the outer wall of the inner pipe 21;
[0043] Both ends of the core pipe 1 are provided with splicing plates 12, and the splicing plates 12 are provided with splicing holes 121.
[0044] In some embodiments, the pipe frame 31 can be made of metal material to improve the strength of the pipe frame 31. During long-term use, the pipe frame 31 plays a role in positioning the sound attenuation bodies 32, and on the other hand, the pipe frame 31 also plays a role in protecting the core pipe 1, that is, even if the protective pipe 2 is damaged, the core pipe 1 is not easy to be damaged under the protection of the pipe frame 31, thereby prolonging the service life of the drain pipe.
[0045] Referring to Figures 1 to 6In some embodiments, the guide vane 11 can be made of metal material, or the guide vane 11 can be made of non-metal material. When the guide vane 11 is made of metal material, the guide vane 11 can be made of stainless steel, or the guide vane 11 can be coated with rust-proof paint to prevent rusting of the guide vane 11.
[0046] In some embodiments, a metal protective net can be arranged in the protective pipe 2 to further improve the strength of the protective pipe 2.
[0047] In some embodiments, the pipe frame 31 is provided with a mounting groove 311 for mounting the sound-absorbing body 32, the mounting groove 311 penetrates through the pipe frame 31, and the mounting grooves 311 are uniformly distributed on the side wall of the pipe frame 31.
[0048] The cross-sectional shape of the mounting groove 311 can be polygonal, or the cross-sectional shape of the mounting groove 311 can also be circular.
[0049] In some embodiments, the thickness of the sound-absorbing body 32 is not less than the thickness of the pipe frame 31, and the sound-absorbing body 32 is clamped in the mounting groove 311.
[0050] In some embodiments, the sound-absorbing body 32 is sound-absorbing cotton, or the sound-absorbing body 32 is a sponge block.

The diameter of the through hole is preferably as small as possible, as long as a part of the water guided by the guide vane 11 can flow through the through hole. By arranging the through hole, a part of the water guided by the guide vane 11 flows downward through the through hole under the action of gravity, impacting the water flow in the core pipe 1, so that the water flow in the core pipe 1 has a better turbulent effect, thereby further preventing the dirt in the water flow from depositing in the core pipe 1 and preventing the core pipe 1 from being blocked.

The number of guide vanes 11 should not be too large to prevent the arrangement of guide vanes 11 from reducing the drainage performance of the core pipe 1. At the same time, too many guide vanes 11 can increase the flow resistance in the core pipe 1 and reduce the flow speed, and the like, which are not conducive. Therefore, the number of guide vanes 11 is preferably one or two.
[0056] Referring to Figures 1 to 6 In some embodiments, the inner pipe 21 and the protective rib 22 are in an integrated structure, and the cross-sectional shape of the protective rib 22 is a polygon.

[0058] The protective rib 22 can also include ribs arranged in other directions, such as spirally arranged ribs, and the like. The more the number of protective ribs 22, the higher the strength of the protective pipe 2, and the better the protection performance of the protective pipe 2.
[0059] Referring to Figures 1 to 6 In some embodiments, the splice plate 12 is welded to both ends of the core pipe 1, or the splice plate 12 is fixed to both ends of the core pipe 1 by detachable connection.
[0060] For example, the splice plate 12 can be fixed to the core pipe 1 by using screws and the like. In the production process, the core pipe 1, the protective pipe 2, and the sound attenuation pipe 3 should be assembled first, and then the splice plate 12 is fixed to the core pipe 1.

The protective pipe 2 and the sound attenuation pipe 3, and the sound attenuation pipe 3 and the core pipe 1 can be in a connected relationship, so that the protective pipe 2, the core pipe 1, and the sound attenuation pipe 3 can be independently replaced.
[0062] In some embodiments, the splice plate 12 is provided with a ring groove 122 for mounting a sealing ring, and the ring groove 122 is coaxially arranged with the core pipe 1.
[0063] The ring groove 122 can have multiple ring grooves to allow the splice plate 12 to mount more sealing rings to prevent leakage between two drainage pipes spliced at the head and tail.
[0064] The above introduces the subject technical scheme of the utility model and corresponding details, and it can be understood that the above introduction is only some implementation of the subject technical scheme of the utility model, and some details can be omitted in the specific implementation.
[0065] In addition, in some embodiments of the above utility model, multiple embodiments can be combined for implementation, and various combination schemes are not listed one by one due to the length limit. Those skilled in the art can freely combine the above embodiments according to the needs in the specific implementation to obtain better application experience.
