Description

Technical Field

[0001] The utility model belongs to the technical field of noise reduction of drainage pipes, and particularly relates to a noise reduction drainage pipe for high-rise buildings. Background Art

[0002] The statements herein only provide background art related to the utility model and do not necessarily constitute prior art.

[0003] As an essential building material in house construction, drainage pipes are used to discharge domestic sewage from residential buildings. The water flow impacts the pipe wall of the drainage pipe to generate noise. Especially for residents on lower floors, the height difference of the water falling is greater, and the increase in water speed makes the generated noise greater, which affects the normal rest of residents.

[0004] In the prior art, the Chinese utility model patent CN220168787U discloses a noise reduction PVC drainage pipe. By setting threads on the inner wall of the PVC pipe and sleeving a sound insulation pipe outside, the threads are used to guide the water flow along the pipe wall, achieving the effect of reducing noise. The above structure cannot comprehensively and effectively control the noise problem because various forms of noise will be generated when water flows in the drainage pipe, such as pressure drop noise, flow impact noise, vibration noise transmitted by the building structure, etc. The design of the threads in the above structure is fixed and cannot be adaptively adjusted according to different flow rate changes and operating conditions. This results in the noise control effect being affected when the water flow rate changes greatly or different drainage pipes are in different working states. Therefore, the prior art has limitations in terms of adaptability and flexibility. In addition, the shock absorption bracket design at the connection between the drainage pipe and the building structure in the prior art is not stable enough. The vibration generated when water flows through the pipe will be transmitted to the building structure, resulting in noise propagation and pipe vibration problems, and no effective solution is provided to reduce the structure noise and vibration. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a noise reduction drainage pipe for high-rise buildings. By combining multiple noise control means, it can comprehensively control the pressure drop noise and flow impact noise caused by the water flow in the drainage pipe, and reduce the generation and propagation of noise.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0007] In a first aspect, an embodiment of the utility model provides a noise reduction drainage pipe for high-rise buildings, including a drainage pipe body. An acoustic absorption sleeve is sleeved outside the drainage pipe body. Flow adjustment silica gel is arranged on the inner wall of the drainage pipe body, and the flow adjustment silica gel can change the flow area according to the water volume, thereby buffering the water flow; a shock absorption structure is arranged at the connection between the drainage pipe body and the building structure.

[0008] As a further technical solution, the flow regulating silica gel is made of soft silica gel. When water flows through the soft silica gel, the soft silica gel can deform, and when the water flows through the soft silica gel, the soft silica gel can return to its original state.

[0009] As a further technical solution, the flow regulating silica gel is fixed on the inner wall of the drain pipe body by bonding, and the flow regulating silica gel is in an arc-shaped convex shape on the inner wall of the drain pipe body.

[0010] As a further technical solution, two flow regulating silica gels are provided, and the two flow regulating silica gels are arranged oppositely.

[0011] As a further technical solution, the wall thickness of the sound-absorbing sleeve is greater than the wall thickness of the drain pipe body.

[0012] As a further technical solution, the shock absorption structure includes a shock absorption sleeve, and the shock absorption sleeve is sleeved outside the sound-absorbing sleeve.

[0013] As a further technical solution, there is a gap between the outer wall surface of the sound-absorbing sleeve and the inner wall surface of the shock absorption sleeve, and they are connected by a plurality of shock absorption springs.

[0014] As a further technical solution, the plurality of shock absorption springs are evenly distributed in the circumferential direction.

[0015] As a further technical solution, the installation height of the shock absorption sleeve is equal to the height where the drain pipe contacts the building structure.

[0016] As a further technical solution, the shock absorption sleeve is made of rubber material.

[0017] The beneficial effects of the above embodiments of the present invention are as follows:

[0018] (1) The noise reduction drain pipe for high-rise buildings provided by the present invention controls the water flow noise in various ways, thereby effectively reducing the noise level generated by the drainage system of high-rise residential buildings. This noise reduction drain pipe not only has the advantages of remarkable noise reduction effect, but also is easy to install and will not have a negative impact on the normal drainage function of the drainage system. By using this drain pipe, a more quiet and comfortable living environment can be created for residents.

[0019] (2) The noise-reducing drain pipe for high-rise buildings provided by the present utility model has an adaptive adjustment function. The flow-regulating silica gel can automatically adjust the size of the throttle opening according to the change of water flow rate to keep the water flow running within the optimal speed range. This characteristic helps to effectively reduce the pressure-drop noise under different flow conditions and provides a more stable noise control effect. By reducing the vibration conduction to the building structure through the shock-absorbing structure, not only can the noise transmission be reduced, but also it helps to prevent problems such as damage or detachment of the pipe due to vibration.

[0020] (3) For the pressure-drop noise generated in the drain pipe of the noise-reducing drain pipe for high-rise buildings provided by the present utility model, the flow-regulating silica gel provided plays a buffering role, reducing the water flow velocity and noise.

[0026] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0027] Embodiment 1

[0028] In a typical implementation manner of the present utility model, as Figure 1 and Figure 2As shown in the figure, a noise-reducing drain pipe for high-rise buildings is provided, including a drain pipe body 1. An acoustic absorption sleeve 2 is sleeved outside the drain pipe body 1. A flow-regulating silica gel 5 is arranged on the inner wall of the drain pipe body 1. The flow-regulating silica gel 5 can change the flow area according to the water volume, thereby buffering the water flow. A shock-absorbing structure is arranged at the connection between the drain pipe body 1 and the building structure.

[0029] In this embodiment, the flow-regulating silica gel 5 is made of soft silica gel. The soft silica gel has certain toughness and elasticity. Under a certain pressure, the soft silica gel is easy to deform, and when the pressure disappears, the soft silica gel can return to its original state. In this embodiment, the characteristics of the soft silica gel are utilized. When the water flow passes through the soft rubber, the soft rubber can deform, and when the water flow passes through the soft silica gel, the soft silica gel can return to its original state. In this way, no matter whether the water flow is large or small, it can play a certain buffering role when passing through the soft silica gel, reducing the flow rate, and when the height of the drain pipe is too high, the water flow can be prevented from impacting the drain pipe, thereby achieving a noise-reducing effect.

[0030] In this embodiment, the flow-regulating silica gel 5 is fixed on the inner wall of the drain pipe body 1 by bonding. The flow-regulating silica gel 5 is in an arc-shaped convex shape on the inner wall of the drain pipe body. The glue for bonding the flow-regulating silica gel is selected as waterproof glue to prevent the flow-regulating silica gel from falling off. Of course, other fixing methods can also be used, which are existing technologies and will not be elaborated here.

[0031] In a specific implementation manner of this embodiment, two flow-regulating silica gels 5 are provided, and the two flow-regulating silica gels 5 are arranged oppositely. The flow-regulating silica gel 5 can also be arranged at any place where noise is likely to be generated in the drain pipe according to needs.

[0032] In this embodiment, the wall thickness of the acoustic absorption sleeve 2 is greater than the wall thickness of the drain pipe. The acoustic absorption sleeve is made of a material with excellent acoustic absorption performance. The acoustic absorption material sleeve can effectively absorb the noise generated by the water flow and reduce the transmission of noise.

[0033] In this embodiment, the shock-absorbing structure includes a shock-absorbing sleeve 4. The shock-absorbing sleeve 4 is sleeved outside the acoustic absorption sleeve 2. The shock-absorbing sleeve 4 is made of rubber material. The shock-absorbing sleeve 4 can be closely attached to the outside of the shock-absorbing sleeve 4, which can reduce the possibility of the drain pipe vibration being transmitted to the building structure and further reduce the transmission of noise.

[0034] In order to further improve the shock-absorbing effect, a gap can also be left between the outer wall surface of the acoustic absorption sleeve 2 and the inner wall surface of the shock-absorbing sleeve 4, and they are connected by a plurality of shock-absorbing springs 3. The plurality of shock-absorbing springs 3 are evenly distributed in the circumferential direction. In this way, the vibration of the drain pipe is completely controlled within the shock-absorbing sleeve, and the vibration of the drain pipe will not be transmitted to the building structure, avoiding the transmission of noise.

[0035] In this embodiment, the installation height of the shock-absorbing sleeve 4 is equal to the height at which the drain pipe contacts the building structure. When the drain pipe is connected to the building structure through a bracket, the shock-absorbing sleeve 4 can be arranged inside the bracket.

[0036] In this embodiment, the drain pipe is made of PVC material.

[0037] The noise-reducing drain pipe for high-rise buildings provided in this embodiment can also be used as a noise-reducing device and connected to positions where the pipeline is prone to generate noise, such as vertical pipelines or elbow parts.

[0038] For the pressure-drop noise generated by the drain pipe, the flow-regulating silica gel provided in the noise-reducing drain pipe for high-rise buildings provided in this embodiment plays a buffering role, reduces the water flow velocity, and reduces noise. At the same time, the flow-regulating silica gel can also reduce the noise of flow impact; for the flow impact noise, the noise generated by the water flow is effectively absorbed through the provided suction sleeve, reducing the propagation of noise; for the vibration noise transmitted by the building structure, the possibility of pipeline vibration being transmitted to the building structure is reduced through the provided shock-absorbing structure, further reducing the propagation of noise; the water flow noise is controlled in various ways, thereby effectively reducing the noise level generated by the drainage system of high-rise residential buildings. This device not only has the advantage of significant noise reduction effect, but also is easy to install and will not have a negative impact on the normal drainage function of the drainage system. By using the drain pipe with this structure, a quieter and more comfortable living environment can be created for residents.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
