Description

Technical Field

[0001] The invention belongs to the technical field of pipelines and relates to a noise reduction and energy dissipation device for a riser. Background Art

[0002] Drain pipes are basically installed in buildings. Drain pipes usually adopt vertical pipes, which are convenient for the rapid discharge of water. Vertical pipes are used between floors. Therefore, when draining, water enters the pipe and falls vertically, which generates a lot of noise. In addition, the water flow and the return air flow will collide, resulting in the inability to discharge the air smoothly, which has a great impact on the residents. In addition, since the vertical pipe is subjected to a large impact force for a long time, the bottom of the vertical pipe is more prone to damage, which also affects the overall use of the vertical pipe.

[0003] In response to the above problems, people have developed various noise reduction and energy dissipation devices for risers:

[0004] For example, the Chinese patent application [Authorization Announcement No.: CN211398946U] discloses a buffering and noise-reducing double-clamped 45-degree elbow pipe, including a riser, a bending pipe, a connecting pipe, a nickel-based alloy layer and a sealing assembly. The riser, the bending pipe and the connecting pipe are integrally formed from top to bottom, and a nickel-based alloy layer is arranged inside the riser, the bending pipe and the connecting pipe. A sealing assembly is arranged at the lower part of the connecting pipe. A sound insulation device is arranged between the lower part of the riser, the bending pipe and the upper part of the connecting pipe. The lower part of the inner wall of the nickel-based alloy layer is fixedly connected to the buffer device, and also includes a sound insulation device and a buffer device. The sound insulation device includes a groove and a sound insulation felt. The inner wall of the groove is bonded to the sound insulation felt by strong glue. A groove is arranged between the lower part of the riser, the bending pipe and the upper part of the connecting pipe.

[0005] The above structure achieves the silencing effect by providing an elastic plastic plate and an intermediate groove, and then achieves buffering by providing a curved pipe and providing an elastic plastic plate on the curved pipe, thereby further improving the buffering effect of the curved pipe. However, since the vertical pipe, the curved pipe and the connecting pipe are all integrally formed, the vertical pipe needs to be reprocessed, and other components need to be added to the original vertical pipe. Since the vertical pipe is long, it is difficult to reprocess it, which makes the reprocessing of the vertical pipe more difficult and increases the installation cost. In addition, the buffering effect is limited by only providing the curved pipe for buffering. Moreover, the elastic plastic plate is only provided on the bottom surface of the front end of the curved pipe, so it can only buffer the water flowing down from the vertical pipe. However, after the water flowing down from the vertical pipe collides with the elastic plastic plate, part of it will splash onto other inner walls of the curved pipe, and there will still be a problem of poor buffering effect. Summary of the invention

[0006] The purpose of the present invention is to address the above problems in the existing technology and propose a noise reduction and energy dissipation device for a riser. The technical problem to be solved by the present invention is: how to solve the problem of high installation cost and poor buffering effect of the existing noise reduction and energy dissipation device.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A noise reduction and energy dissipation device for a riser, the riser includes an upper socket and a lower socket, the noise reduction and energy dissipation device includes a mounting box, the mounting box is located between the upper socket and the lower socket, and is characterized in that the upper socket is connected to the upper end of the mounting box, the lower socket is connected to the lower end of the mounting box, the upper socket and the lower socket are both connected to the inner cavity of the mounting box, the mounting box is provided with a plurality of guide plates arranged inclined downward, the lower ends of the guide plates are inclined toward the inside of the mounting box, the plurality of guide plates are staggered, a water gap is formed between two adjacent guide plates, and one of the guide plates is partially located below the upper socket and is arranged directly opposite to the water outlet of the upper socket.

[0009] By setting the installation box, the upper socket is connected to the upper end of the installation box, and the lower socket is connected to the lower end of the installation box, and the water flows into the installation box from the water outlet of the upper socket, and the water flowing into the installation box from the water outlet of the upper socket directly collides with one of the guide plate parts. Since one of the guide plate parts is located below the upper socket and is arranged directly opposite to the water outlet of the upper socket, part of the water at the water outlet of the upper socket collides with the guide plate, and the other part of the water directly flows to the next guide plate, and the guide plate is tilted downward, so that part of the water that collides with the guide plate will flow after the collision. Most of it rebounds into another part of the water, causing the other part of the water to collide with this part of the water, thereby consuming the kinetic energy of the other part of the water, thereby reducing the flow rate of the other part of the water. The guide plate can be slightly deformed after the water flow hits it to buffer the water flow, so that most of the water flows downward along the guide plate after colliding with the guide plate, which can also play a buffering role, further improving the buffering effect of the noise reduction and energy dissipation device. The flow noise of the buffered water flow is reduced, and the water flow directly hits the guide plate, so that the water flow can achieve a better noise reduction and buffering effect.

[0010] Since no structural improvement was made to the original riser in this case, the original riser can continue to be used, thereby avoiding reprocessing of the original riser, saving the installation cost of the noise reduction and energy dissipation device, and achieving a good buffering effect through the installation box and the guide plate inside the installation box, further achieving the improvement of its buffering effect while reducing the installation cost of the noise reduction and energy dissipation device.

[0011] In the above-mentioned riser noise reduction and energy dissipation device, a buffer sleeve made of elastic material is provided in the installation box, the buffer sleeve is in contact with the inner wall of the installation box, the guide plate is a downwardly concave arc plate, and one end of the guide plate is connected to the inner wall of the buffer sleeve.

[0012] The guide plate is set as a downwardly concave arc plate, so that when the water flow hits the guide plate, the guide plate can drop part of the water splashed after the impact back onto the guide plate, thereby further improving the buffering effect of the guide plate; and the guide plate is connected to the inner wall of the buffer sleeve, which prevents the water flow flowing into the guide plate from flowing out from the gap between the guide plate and the buffer sleeve, affecting the buffering effect of this part of the water flow.

[0013] In the above-mentioned riser noise reduction and energy dissipation device, the buffer sleeve is made of rubber material, the installation box includes a box body and a box cover, the box body is connected to the upper socket and the lower socket, the buffer sleeve includes a sleeve body arranged in the box body and a sleeve cover arranged on the box cover, the box cover is connected to the sleeve body through fasteners and presses the sleeve cover onto the sleeve body.

[0014] Since the buffer sleeve is made of rubber material, rubber is prone to corrosion during long-term use. Therefore, after a period of use, the buffer sleeve in the noise reduction and energy dissipation device needs to be replaced. By arranging a box body, a box cover, a sleeve body and a sleeve cover, the box cover and the buffer sleeve can be detachably connected, and by removing the fasteners, the sleeve body in the box body and the sleeve cover on the box cover can be taken out and replaced, thereby achieving a better buffering effect while also making the maintenance of the noise reduction and energy dissipation device more convenient.

[0015] In the above-mentioned riser noise reduction and energy dissipation device, the lower end of the upper socket passes through the box body and the sleeve body, and the lower end portion of the upper socket is located in the inner cavity of the buffer sleeve and is arranged opposite to one of the guide plates.

[0016] The lower end of the upper bearing is located in the inner cavity of the buffer sleeve, so that the water flowing into the buffer sleeve from the upper bearing can directly fall vertically into the buffer sleeve, avoiding part of the water sliding along the inner wall of the buffer sleeve, and further improving the buffering effect of the noise reduction and energy dissipation device.

[0017] The upper socket part is arranged in the inner cavity of the installation box, and the upper socket and the installation box are sealed and connected through a sealing ring, and the lower end of the lower socket is connected to the box body through an adhesive.

[0018] In the above-mentioned noise reduction and energy dissipation device for the riser, one side of the guide plate is connected to the bottom wall of the sleeve body, and the other side of the guide plate is connected to the sleeve cover.

[0019] The arrangement of this structure enables the water flowing into the guide plate to be buffered and guided by the guide plate, and will not flow out from the guide plate and the bottom wall of the sleeve body and between the guide plate and the sleeve cover, further ensuring the buffering and guiding effect of the guide plate.

[0020] In the above-mentioned riser noise reduction and energy dissipation device, there are two guide plates, namely guide plate 1 and guide plate 2. Guide plate 1 is located above guide plate 2, and guide plate 1 and guide plate 2 are respectively located on the left and right sides of the installation box.

[0021] Since a buffer sleeve has been provided in the installation box in this case, only guide plate 1 and guide plate 2 are provided to achieve noise reduction and energy dissipation of the water in the vertical pipe. The specific arrangement of guide plate 1 and guide plate 2 enables the water in the vertical pipe to flow roughly along an S shape, making the flow of the water smoother, and also increasing the flow path of the water, further reducing the flow velocity of the water, thereby playing a better buffering role.

[0022] In the above-mentioned noise reduction and energy dissipation device of the riser, a part of the guide plate is located below the upper socket, and the second guide plate is located outside the upward projection range of the water inlet of the lower socket.

[0023] The specific position setting of the guide plate 2 ensures that the guide plate 2 does not affect the water outlet of the noise reduction and energy dissipation device, and makes the water in the installation box flow into the lower socket more smoothly.

[0024] In the above-mentioned riser noise reduction and energy dissipation device, the sleeve body is provided with a plurality of connecting columns, the box cover is passed through the connecting columns and connected to the box body through fasteners, and the above-mentioned connecting columns are provided at both ends of the guide plate 1 and the guide plate 2.

[0025] The setting of the connecting column can, on the one hand, enhance the structural strength of the buffer sleeve, and on the other hand, improve the stability of the connection between the mounting box and the buffer sleeve; and connecting columns are provided at both ends of the guide plate 1 and the guide plate 2, so that when the guide plate 1 and the guide plate 2 are deformed, due to the higher strength at the two ends, the middle part of the guide plate 1 and the guide plate 2 is deformed, thereby making it easier for the water after the collision of the guide plate 1 and the guide plate 2 to flow back into the guide plate 1 and the guide plate 2, further improving the buffering effect of the noise reduction and energy dissipation device.

[0026] In the above-mentioned noise reduction and energy dissipation device for the riser, the longitudinal section of the installation box is elliptical.

[0027] The arrangement of this structure can maximize the rapid flow of water after colliding with the guide plate into the middle of the installation box, and can relatively extend the length of the installation box, thereby improving the flow path of the water flow, thereby achieving the purpose of improving the buffering effect.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. Since no structural improvement was made to the original riser in this case, the original riser can continue to be used, thereby avoiding reprocessing of the original riser, saving the installation cost of the noise reduction and energy dissipation device, and achieving a better buffering effect through the installation box and the buffer sleeve in the installation box, further achieving the improvement of its buffering effect while reducing the installation cost of the noise reduction and energy dissipation device.

[0030] 2. Since the buffer sleeve is made of rubber material, rubber is prone to corrosion during long-term use. Therefore, after a period of use, the buffer sleeve in the noise reduction and energy dissipation device needs to be replaced. By arranging a box body, a box cover, a sleeve body and a sleeve cover, the box cover and the buffer sleeve can be detachably connected, and by removing the fasteners, the sleeve body in the box body and the sleeve cover on the box cover can be taken out and replaced, thereby achieving a better buffering effect while also making the maintenance of the noise reduction and energy dissipation device more convenient.
