They supply water in different quantities and qualities to various types of users to meet their different needs, and at the same time, they are responsible for the collection, transportation, and treatment of wastewater discharged by users, so as to eliminate pollutants in wastewater from human health and protect the environment.

[0003] In building water supply and drainage systems, the laying of pipes is essential. These pipes must pass through floors or walls during the laying process, and are therefore collectively referred to as through-wall pipes. Currently, the through-wall pipes used in buildings are surrounded by the floor slab or wall. Through-wall pipes generally adopt a single-layer structure, and the inner wall of the pipe is a smooth arc surface.

[0004] As water flows through the pipes, the impact of the water flow can generate significant noise, which can easily disrupt residents' lives. Utility Model Content

[0007] The fixing assembly includes a base fixedly connected to the side of the noise-reducing housing and a cover detachably mounted on the top of the base. Both ends of the base have connecting grooves, and both ends of the cover have connecting blocks that are adapted to the connecting grooves. One side of the connecting block has a locking groove. The base has a cavity between the two connecting grooves on the same side. A bidirectional screw is rotatably installed in the cavity. A drive assembly is connected to the middle of the bidirectional screw. Two symmetrical sliders are threaded onto the bidirectional screw. One side of each slider is fixedly connected to a locking rod that is adapted to the locking groove.

[0008] In a preferred embodiment, both the gland and its inner wall are fixedly connected with rubber pads.

[0009] In a preferred embodiment, both the gland and its interior are filled with a second sound-insulating cotton.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a sound-absorbing through-wall pipe for building water supply and drainage, including a pipe body 1, a noise-reducing outer shell 2, and a fixing component 3. The pipe body 1 passes through the noise-reducing outer shell 2 and is fixedly installed to the noise-reducing outer shell 2 by the fixing component 3. The interior of the noise-reducing outer shell 2 is filled with a first sound-insulating cotton 21. Both ends of the noise-reducing outer shell 2 have through holes that match the pipe body 1. By setting the noise-reducing outer shell 2, it can be pre-installed in the building wall during construction. When the pipe body 1 passes through the wall, it can pass through the noise-reducing outer shell 2, so that the first sound-insulating cotton 21 can reduce noise and sound insulation for the pipe body 1. When noise is generated inside the pipe body 1, the first sound-insulating cotton 21 can absorb sound waves, reduce the transmission of noise, and avoid affecting the lives of residents. Specifically, the fixing component 3 includes a base 31 fixedly connected to the side of the noise reduction housing 2 and a pressure cover 32 detachably installed on the top of the base 31. Both the pressure cover 32 and the inner wall of the pressure cover 32 are fixedly connected with rubber pads 310. Both the pressure cover 32 and the pressure cover 32 are filled with second sound insulation cotton 311. With the setting of the fixing component 3, after the tube 1 passes through the noise reduction housing 2, the fixing component 3 can be used to fix the tube 1, the rubber pads 310 can be used to dampen and buffer the tube 1, and the second sound insulation cotton 311 can further reduce the noise transmission inside the tube 1.

[0023] Specifically, the base 31 has connecting grooves 33 at both ends, and the pressure cap 32 has connecting blocks 34 at both ends that are adapted to the connecting grooves 33. A locking groove 35 is provided on one side of each connecting block 34. A cavity is formed between the two connecting grooves 33 on the same side of the base 31. A bidirectional screw 36 is rotatably installed within the cavity. A drive assembly 37 is connected to the middle of the bidirectional screw 36. Two symmetrical sliders 38 are threaded onto the bidirectional screw 36. A locking rod 39 adapted to the locking groove 35 is fixedly connected to one side of each slider 38. A guide rod 314 is fixedly installed inside the cavity. The slider 38 is slidably sleeved on the guide rod 314. With the setting of the drive component 37, when fixing the tube body 1, the pressure cap 32 is placed on the base 31, so that the pressure cap 32 cooperates with the base 31 to press the tube body 1. At the same time, the connecting block 34 will be inserted into the corresponding connecting groove 33. Then, only the drive component 37 needs to be operated. The drive component 37 drives the bidirectional screw 36 to rotate, so that the bidirectional screw 36 drives the two sliders 38 to move in opposite directions along the guide rod 314, so that the sliders 38 drive the locking rod 39 to insert into the locking groove 35 of the connecting block 34, thereby fixing the pressure cap 32.

[0024] Specifically, the drive assembly 37 includes a nut 371, a worm 372, and a worm wheel 373. The nut 371 is fixedly installed at the end of the worm 372, which extends rotatably into the cavity. The worm wheel 373 is fixedly installed in the middle of the bidirectional screw 36 and meshes with the worm 372. When operating the drive assembly 37, a tool can be used to rotate the nut 371, causing the nut 371 to drive the worm 372 to rotate, which in turn drives the worm wheel 373 to rotate, which in turn drives the bidirectional screw 36 to rotate.

[0025] Furthermore, a groove 312 is provided on the side wall of the base 31, and a cover plate 313 is hinged to the opening of the groove 312. The nut 371 is embedded in the groove 312. The groove 312 and the cover plate 313 can protect the nut 371.

[0026] The working principle and usage process of this utility model are as follows: First, during building construction, the noise-reducing shell 2 can be pre-installed inside the building wall. When the pipe body 1 passes through the wall, it can be passed through the noise-reducing shell 2. After the pipe body 1 passes through the noise-reducing shell 2, the pressure cap 32 is placed on the base 31, so that the pressure cap 32 and the base 31 press the pipe body 1 together. At the same time, the connecting block 34 will be inserted into the corresponding connecting groove 33. Then, the nut 371 can be rotated with a tool, so that the nut 371 drives the worm gear 372 to rotate, and the worm gear 372 drives the worm wheel 373 to rotate. The worm gear 373 drives the bidirectional screw 36 to rotate, causing the bidirectional screw 36 to drive the two sliders 38 to move in the opposite direction along the guide rod 314. The sliders 38 drive the locking rod 39 to insert into the locking groove 35 of the connecting block 34, thus fixing the pressure cap 32. The pressure cap 32, together with the base 31, fixes the tube body 1. The rubber pad 310 is used to dampen and buffer the tube body 1. When noise is generated inside the tube body 1, the first sound insulation cotton 21 and the second sound insulation cotton 311 can absorb sound waves, reduce the transmission of noise, and avoid affecting the lives of residents.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
