Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a drainage pipe sound insulation structure. Background Art

[0002] As a necessary structure of a building, the drain pipe is the key to ensure the smooth drainage of the building. At present, the common drain pipes in buildings on the market are vertical pipes and horizontal pipes. The vertical pipe is usually the main channel, and the horizontal pipe is usually the channel branch, which is used to connect the main channel and the drainage end, that is, multiple drainage ends are connected to the vertical pipe through the corresponding horizontal pipe to achieve the discharge of water after collection.

[0003] Since the vertical pipe is the main pipe for water to be discharged after being collected, the water flow is large and the flow rate is fast, which causes the greatest noise when it is draining. Therefore, it is necessary to soundproof the vertical pipe. Existing building isolation drainage pipes, such as the sound insulation and noise reduction building drainage pipe disclosed in patent CN110285273A, include a drainage pipe body and a noise reduction device. At this time, the drainage pipe body includes a drainage inner pipe, the outer wall of the drainage inner pipe is covered with a sound-absorbing inner layer, and the outer surface of the peripheral side of the sound-absorbing inner layer is covered with a sound insulation cotton tube. The noise reduction device includes a supporting device and a linkage device installed on the supporting device, two sliding plates arranged opposite to each other, the supporting device includes a fixed plate, and springs are evenly distributed on the surface of the fixed plate, and the other end of the spring is fixed to the lower surface of the buffer plate. The linkage device includes two screw rods and two gears. The threaded rod is installed through the two mounting plates, and the two gears are respectively fixed on the two threaded rods. When in use, the corresponding threaded rod is driven to rotate by the rotation of the two gears, and then the two mounting plates are driven by the threaded rod to clamp the drainage pipe body, which can not only perform sound absorption operation through the sound-absorbing inner layer and the sound insulation cotton tube of the drainage pipe body, but also reduce the noise generated by the impact vibration of the pipeline through the spring in the external noise reduction device, thereby achieving double noise reduction. Although the above structure can already meet the demand for noise reduction, the sound-absorbing inner layer of the drain pipe body is arranged outside the outer wall of the drain inner pipe, the sound-insulating cotton tube is arranged on the outer periphery of the sound-absorbing inner layer, and the noise reduction device is arranged outside the drain pipe body, resulting in the sound insulation and noise reduction structure being arranged on the outside of the drain inner pipe, and there being no noise reduction structure inside the drain inner pipe. As a result, it needs to occupy more space outside the pipe when meeting the same sound insulation effect. For some environments with small spaces, its installation is very inconvenient, or the sound insulation effect is affected by reducing the sound insulation structure, which is not conducive to the use of the drain pipe. Summary of the invention

[0004] In view of the above-mentioned problems existing in the prior art, the present invention aims to provide a sound insulation structure for a drainage pipe, in which a plurality of water guide plates are spirally distributed along the axial direction of an inner pipe, and an elastic component is arranged between each water guide plate and the pipe wall of the inner pipe. In addition, a sound insulation cotton sleeve is arranged on the outer side of the inner pipe, and a sound-absorbing outer pipe is arranged outside the sound insulation cotton sleeve, so that when water flows through the inner pipe, it can descend in an orderly and spiral manner along the water guide plate, effectively avoiding the noise generated by the impact of the water flow on the pipe wall of the inner pipe. In addition, each water guide plate has an elastic component, which can reduce shock and absorb energy when the water flow impacts the water guide plate. At the same time, by arranging a sound insulation cotton sleeve on the outer side of the inner pipe and by arranging a sound-absorbing outer pipe, the sound insulation effect is further improved, and the sound insulation structure is arranged inside and outside the pipe, while achieving the same sound insulation effect, the external space occupancy is reduced, it can better adapt to the use environment with narrow space, and the installation is more convenient, which is conducive to the use of drainage pipes.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 4 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0028] Figure 1 A structural diagram of an embodiment of a drainage pipe sound insulation structure of the utility model; Figure 2 This is a structural diagram of a water guide plate installed in an inner tube of a preferred embodiment of the utility model. Figure 1 and Figure 2 As shown, the drainage pipe sound insulation structure provided in this embodiment includes: an inner pipe 1, a plurality of water guide plates 2, a plurality of elastic components 3, a sound insulation cotton sleeve 4 and a sound absorbing outer pipe 5.

[0029] Specifically, a plurality of mounting holes 11 are provided on the side wall of the inner tube 1, so that a plurality of mounting positions are arranged correspondingly on the inner tube 1, providing a mounting basis for the subsequent installation of the water guide plate 2 in the inner tube 1. At this time, the plurality of mounting holes 11 are distributed in a spiral state along the axial direction of the inner tube 1, providing a condition for the subsequent water guide plate 2 arranged in the inner tube 1 to be distributed in a spiral state.

[0030] Specifically, a plurality of water guide plates 2 are arranged in the inner tube 1, and a plurality of water guide plates 2 correspond to a plurality of mounting holes 11 one by one, ensuring that each water guide plate 2 has a corresponding mounting structure. At this time, each water guide plate 2 is arranged obliquely with respect to the axial direction of the inner tube 1, so that the water guide plate 2 can provide guidance for the water flow to flow downward, which can slow down the flow rate of the water flow and reduce noise compared to the vertical descent of the water flow. At the same time, a plurality of water guide plates 2 are distributed in a spiral state along the axial direction of the inner tube 1, so that the water flow can descend in an orderly and spiral manner along the water guide plates 2, which can effectively avoid the problem of the water flow impacting the wall of the inner tube 1 and generating a large noise, thereby fundamentally reducing the noise.

[0031] Specifically, an elastic component 3 is provided between each mounting hole 11 and the corresponding water guide plate 2, that is, each water guide plate 2 is installed on the corresponding mounting hole 11 through an elastic component 3, that is, the elastic component 3 is used as an intermediate structure for installing the water guide plate 2, so that the water guide plate 2 has a certain flexibility, so that when the water flow hits the water guide plate 2, the deformation of the elastic component 3 can achieve energy absorption and shock reduction, further eliminate the impact noise, and improve the sound insulation effect.

[0032] Specifically, the sound insulation cotton sleeve 4 is sleeved on the outside of the inner tube 1, that is, the inner tube 1 is wrapped by the sound insulation cotton sleeve 4, and sound absorption and vibration reduction are performed from the outside of the inner tube 1, thereby further improving the sound insulation effect.

[0033] Specifically, the sound-absorbing outer tube 5 is sleeved on the outside of the sound-insulating cotton sleeve 4. At this time, the noise passing through the sound-insulating cotton sleeve 4 can also be absorbed by the suction outer tube located outside the sound-insulating cotton sleeve 4, further ensuring the sound insulation performance. At the same time, the sound-absorbing outer tube 5 can also be used as an external protective structure, and the structural design is more reasonable.

[0034] More specifically, the mounting hole 11 arranged on the inner tube 1 is set as a hole that penetrates the side wall of the inner tube 1, so that the assembler and the later maintenance personnel can install the elastic component 3 and the water guide plate 2 from the outside of the inner tube 1, which is more convenient for disassembly and assembly. In addition, a reinforcing plate 12 is arranged on the outer wall of the inner tube 1 and at each mounting hole 11. The reinforcing plate 12 improves the structural strength of the mounting hole 11 on the inner tube 1, thereby ensuring that the elastic component 3 and the guide plate installed through the mounting hole 11 are better in stability and stronger in bearing capacity. At the same time, when the mounting hole 11 penetrates the side wall of the inner tube 1, it also penetrates the reinforcing plate 12, which is also convenient for disassembly and assembly of the elastic component 3 and the water guide plate 2.

[0035] Figure 3 FIG. 3 is a structural diagram of an elastic component 3 of a preferred embodiment of the present utility model. Figures 1 to 3 As shown, as the intermediate structure for the water guide plate 2 to be installed on the inner tube 1, the elastic component 3 includes a mounting block 31, a mounting frame 32 and a spring 33. At this time, a connection hole 312 corresponding to the mounting hole 11 is opened on one side of the mounting block 31, and the mounting block 31 provides a sufficient processing area for the arrangement of the connection hole 312. At the same time, the mounting frame 32 is arranged on the other side of the mounting block 31, and a spring 33 is arranged on the mounting frame 32. During installation, the corresponding water guide plate 2 is installed on the spring 33, that is, the connection hole 312 on the mounting block 31 is used to cooperate with the mounting hole 11 on the inner tube 1. At the same time, the spring 33 is arranged through the mounting block 31 and the mounting frame 32, and the water guide plate 2 is connected through the spring 33, so that each water guide plate 2 can be reliably installed on the inner tube 1, and each water guide plate 2 can be supported by the spring 33, so that when the water guide plate 2 is impacted, it can absorb energy and reduce vibration, thereby reducing the noise generated.

[0036] More specifically, the mounting frame 32 disposed between the mounting block 31 and the spring piece 33 is a spiral arc structure, so that the mounting frame 32 has a certain length. At this time, when the mounting frame 32 is installed in the inner tube 1, the mounting frame 32 is arranged along the spiral line direction formed by the plurality of water guide plates 2, so that the length extension direction of the mounting frame 32 is also consistent with the spiral line direction of the water guide plates 2, so that the length of the mounting frame 32 can cover the length of the water guide plate 2, providing conditions for achieving all-round support for the water guide plate 2. In addition, a plurality of spring pieces 33 are arranged on the mounting frame 32 at intervals along its length direction. At this time, one side of the corresponding water guide plate 2 is connected to the plurality of spring pieces 33 at the same time, that is, there are a plurality of spring pieces 33 connected between each mounting frame 32 and the corresponding water guide plate 2, so that the connection strength is higher, the impact resistance is stronger, it is not easy to break, and the service life is longer.

[0037] More specifically, the connecting hole 312 on the mounting block 31 is a threaded hole. During subsequent installation, a screw can be passed through the mounting hole 11 and connected and locked with the connecting hole 312, thereby realizing a threaded connection of the mounting block 31 on the inner tube 1, making disassembly and assembly more convenient, and facilitating assembly and subsequent maintenance.

[0038] More specifically, a sealing gasket is also provided on the screw used to connect the connecting hole 312 on the mounting block 31 with the mounting hole 11 of the inner tube 1, that is, when the mounting block 31 is installed on the inner tube 1 by means of the screw and the screw is tightened, the end of the screw presses the sealing gasket against the outer wall of the inner tube 1, and the mounting hole 11 is sealed by the sealing gasket to prevent water leakage in the inner tube 1, thereby providing higher safety assurance.

[0039] More specifically, a plurality of anti-slip teeth 311 are also provided on one side of the mounting block 31 where the connecting hole 312 is provided, that is, when the screw passes through the mounting hole 11 and is connected to the connecting hole 312 and is in place, the anti-slip teeth 311 are pressed against the inner wall of the inner tube 1, and the anti-slip teeth 311 improve the stability of the mounting block 31 pressed against the inner wall of the inner tube 1, thereby preventing the mounting block 31 from accidentally rotating during later use, causing the angle of the water guide plate 2 to change and affecting the noise reduction.

[0040] Figure 4 FIG. 5 is a schematic longitudinal section diagram of a sound-absorbing outer tube 5 of a preferred embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 4 As shown, the sound-absorbing outer tube 5 which is sleeved on the sound-insulating cotton sleeve 4 is configured as a double-layer tube. At this time, irregular foam particles 51 are filled in the double-layer hollow of the sound-absorbing outer tube 5, which not only has a light overall weight, but also can form irregular pores through the irregular surfaces of the irregular foam particles 51, so that the noise transmitted into these pores cannot be transmitted further, thereby achieving noise absorption and further improving the sound insulation effect.

[0041] More specifically, the inner tube of the sound-absorbing outer tube 5 is made of a flexible mesh material, so that when the irregular foam particles 51 are filled into the double-layer hollow of the sound-absorbing outer tube 5, the inner wall of the sound-absorbing outer tube 5 can be close to the outer wall of the sound-insulating cotton sleeve 4, avoiding the problem of forming too large pores and affecting the noise reduction effect. In addition, the outer tube of the sound-absorbing outer tube 5 is made of a hard tube, which can form an external protective package for the entire structure, and the safety protection performance is better.

[0042] The drainage pipe sound insulation structure provided in the present embodiment includes an inner pipe 1, a plurality of water guide plates 2, a plurality of elastic components 3, a sound insulation cotton sleeve 4 and a sound-absorbing outer pipe 5. By distributing a plurality of water guide plates 2 installed on the inner wall of the inner pipe 1 through the elastic components 3 in a spiral state along the axial direction of the inner pipe 1, the water flow can descend in an orderly and spiral manner along the water guide plates 2, effectively avoiding the problem of the water flow impacting the pipe wall of the inner pipe 1 and generating a large noise. At the same time, when the water flow impacts the water guide plates 2, the elastic components 3 can be used for energy absorption and shock reduction, and the noise reduction effect is better. In addition, a sound insulation cotton sleeve 4 is provided on the outer side of the inner pipe 1, and a sound-absorbing outer pipe 5 is provided on the outer side of the sound insulation cotton sleeve 4, which further improves the sound insulation effect and ensures that the sound insulation structure can be distributed inside and outside the pipe body, so that the external space occupation is reduced while achieving the same sound insulation effect, which is convenient for installation in a small space and is conducive to the use of the drainage pipe.
