Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and more specifically, to a sound-absorbing drainage pipeline structure. Background Technology

[0002] A building's water supply and drainage system consists of water supply pipes and drainage pipes. When water flows, it hits the pipe walls, which produces sound.

[0003] Chinese utility model patent with announcement number CN221647873U describes a water supply and drainage noise reduction and protection sleeve, including a first noise reduction plate, a second noise reduction plate connected to the bottom of the first noise reduction plate, a connecting plate provided on the inner wall of the bottom of the first noise reduction plate and the top of the second noise reduction plate, a plurality of noise reduction holes opened inside the connecting plate, and a drainage pipe passing through the two connecting plates.

[0004] The problem solved by the above solution is that, during use, the first and second sound-absorbing plates are installed on the outside of the drain pipe. The plug plate at the bottom of the first sound-absorbing plate is inserted into the inner wall of the second sound-absorbing plate. When water flows through the drain pipe, the noise generated will enter the inner cavity of the first and second sound-absorbing plates through the sound-absorbing holes inside the connecting plate. The first and second sound-absorbing plates are equipped with a first partition and a second partition, which allows the noise to move inside, thereby canceling the noise and improving the sound absorption effect.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sound-absorbing drainage pipe structure.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A noise-reducing drainage pipe structure includes a bend and a straight pipe. The straight pipe is inserted into the bend and fixed to it. A clearance opening is formed in the bend corresponding to the straight pipe. A positioning ring is provided at the clearance opening. The positioning ring abuts against the bend and the straight pipe. A flow guide plate is fixed to the inner side of the positioning ring by several elastic elements. Several flow guide channels are formed between the flow guide plate and the bend, corresponding to the positioning ring.

[0009] The present invention is further configured such that: an extension ring is formed on the end of the guide plate facing the bend, and the extension ring forms a flow channel communicating with a plurality of guide channels.

[0010] The present invention is further configured such that: a guide groove is formed on one side of the extension ring corresponding to the flow channel, and the guide groove is inclined.

[0011] The present invention is further configured such that: the elastic element includes a deformable block, the deformable block has through holes formed at both ends, the guide plate and the positioning ring are both formed with a plurality of support rods for passing through the through holes, and the support rods are formed with stop protrusions.

[0012] The present invention is further configured such that: a deformation opening is formed between the two openings corresponding to the deformation block.

[0013] The present invention is further configured such that: the guide plate is shaped like a frustum, with a smaller cross-section at the end facing the straight pipe and a larger cross-section at the end facing the curved pipe.

[0014] In summary, this utility model has the following beneficial effects:

[0015] Under the action of the guide plate, the water flow is divided into multiple streams and enters several guide channels. The water flows along the wall of the bend. The water flows from the guide channel into the flow channel, and the multiple streams converge into one. When the water flows in the flow channel, due to the concavity of the guide groove, some of the water flows back into the guide groove to flow. This can buffer the water flow and reduce the noise generated by the impact of the bend.

[0016] When water flows through the guide channel, flow channel, and guide groove, it impacts the guide plate and extension ring. Relying on the elasticity and deformation of the deformable block, the vibration transmitted to the straight pipe and bend pipe can be reduced, thereby reducing the generated sound.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1 and Figure 2 As shown, this application provides a sound-absorbing drainage pipe structure, including a bend 1 and a straight pipe 2. The straight pipe 2 can be inserted into the bend 1. A relief opening 3 is formed in the bend 1 corresponding to the straight pipe 2. The relief opening 3 can slide into a positioning ring 4. Before connecting the bend 1 and the straight pipe 2, the positioning ring 4 is slid into the relief opening 3 through the bend 1 until the positioning ring 4 and the bend 1 abut against each other. At this time, the straight pipe 2 coated with adhesive is inserted into the bend 1 until the straight pipe 2 and the positioning ring 4 abut against each other. After the adhesive cures, the straight pipe 2 and the bend 1 are fixed together. The straight pipe 2 and the bend 1 are made of PVC material. PVC material has the characteristics of corrosion resistance and durability, which can improve the service life.

[0024] like Figure 2 and Figure 3 as well as Figure 4 As shown, the inner side of the positioning ring 4 is fixed with a guide plate 5 by several elastic elements, including a deformable block 6. The deformable block 6 has through holes 7 formed at both ends, and a deformation opening is formed between two through holes 7. The deformation opening can increase the overall deformation degree of the deformable block 6. Both the guide plate 5 and the positioning ring 4 are formed with several support rods 8 for passing through the through holes 7. The two ends of the deformable block 6 are connected to the guide plate 5 and the positioning ring 4 respectively. The support rods 8 are formed with stop protrusions 9. The cross section of the through hole 7 is the same as the cross section of the support rod 8. When the support rod 8 and the stop protrusion 9 pass through the through hole 7, the stop protrusion 9 will increase the cross section of the through hole 7 by compression, so that the stop protrusion 9 can pass through. After the stop protrusion 9 passes through the through hole 7, the through hole 7 returns to its original position. The stop protrusion 9 can reduce the probability that the support rod 8 will directly detach from the through hole 7, so as to ensure the connection stability of the deformable block 6 with the guide plate 5 and the positioning ring 4. Relying on the elasticity of the deformable block 6, the guide plate 5 can swing.

[0025] like Figure 2 and Figure 3 as well as Figure 4As shown, the flow guide plate 5 is shaped like a frustum, with a smaller cross-section at the end facing the straight pipe 2 and a larger cross-section at the end facing the bent pipe 1. Several flow guide channels are formed between the flow guide plate 5 and the bent pipe 1 and corresponding to the positioning ring 4. An extension ring 10 is formed at the end of the flow guide plate 5 facing the bent pipe 1. The extension ring 10 forms a flow channel that communicates with the several flow guide channels. A flow guide groove 11 is formed on the side of the extension ring 10 corresponding to the flow channel. The flow guide groove 11 is inclined.

[0026] When the water flow from the straight pipe 2 enters the bend 1, the water flow is divided into multiple streams by the shape of the guide plate 5 and enters several guide channels. The water flows along the wall of the bend 1. The water flows from the guide channels into the flow channel, where multiple streams converge into one. When the water flows in the flow channel, due to the concavity of the guide groove 11, some of the water flows back into the guide groove 11. This setting can buffer the water flow and reduce the sound generated by the impact on the bend 1. At the same time, during this process, the water flow will impact the guide plate 5. When the water flows from the guide channel into the flow channel, the increased space will impact the extension ring 10. At the same time, when the water flows into the guide groove 11, the water flow will impact the side wall of the guide groove 11 again. The inclined guide groove 11 can improve this effect. Relying on the elasticity and deformation of the deformable block 6, the impact energy will be converted into vibration. The deformable block 6 can reduce the vibration transmitted to the straight pipe 2 and the bend 1, further reducing the generated sound.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
