Abstract
Description
Technical Field
[0001] The utility model relates to the field of vertical drainage pipes, in particular to a noise reduction structure for vertical pipes of equipment pipelines. Background Technique
[0002] The vertical pipe of the drainage equipment pipeline, that is, the riser pipe, is a crucial part of the drainage system. It is arranged perpendicular to the horizontal plane. Its main function is to lead water from a lower place to a higher place to ensure the smooth discharge of wastewater and sewage. The riser pipe is not only responsible for water diversion to make the water flow unobstructed, but also undertakes the drainage task, effectively preventing the backflow of wastewater and sewage due to insufficient pipe height. In addition, the riser pipe is usually equipped with auxiliary facilities such as brackets to fix and support the pipeline to ensure its stability during operation, thereby ensuring the normal operation of the drainage system.
[0003] During the use of the vertical pipe of the drainage equipment pipeline, various noises may be generated. When the water flows rapidly in the pipeline or the flow rate is large, it will impact the inner wall of the pipeline, causing pipeline vibration and noise. The intensity of this noise increases with the increase of the water flow velocity. At the same time, the drainage pipeline often contains air. When draining water, the air is compressed, sucked or discharged along with the water flow, and these processes will also generate noises, such as the air mass fluctuations and impact sounds formed by the water flow rolling up the air. In order to alleviate these situations, a spiral rib structure is sometimes arranged inside the pipeline to reduce noise and vibration. However, the traditional spiral ribs still have some defects. For example, the setting of the traditional spiral ribs is often relatively simple, and its noise reduction and vibration reduction effects are limited. Especially in the case of high flow velocity or high flow rate, it may not fully meet the noise reduction requirements. Secondly, the morphological setting of the traditional spiral ribs may lead to an increase in the resistance during the fluid flow process, thereby affecting the drainage efficiency. Content of the Utility Model
[0004] Based on this, the purpose of the present utility model is to provide a noise reduction structure for the vertical pipe of the equipment pipeline to solve the technical problems of the limited noise reduction effect of the traditional spiral ribs, insufficient noise reduction ability in the case of high flow velocity or high flow rate, and the possible increase in fluid flow resistance and influence on drainage efficiency.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A noise reduction structure for the vertical pipe of the equipment pipeline, including a vertical pipeline, wherein a first noise reduction mechanism is arranged on the inner wall of the vertical pipeline, and the first noise reduction mechanism includes a first spiral rib, and an arc-shaped groove is opened on the first spiral rib;
[0006] A plurality of the arc-shaped grooves are provided, and the plurality of arc-shaped grooves are arranged in a spiral array at equal intervals along the first spiral rib.
[0007] By adopting the above technical solution, through the spiral array arrangement of the arc-shaped grooves, the impact energy generated by the water flow or air flow on the inner wall of the pipeline is effectively dispersed, reducing the generation and transmission of noise, thereby improving the noise reduction performance of the pipeline.
[0008] Furthermore, a plurality of the arc-shaped grooves and the first spiral rib form a curved thread structure.
[0009] By adopting the above technical solution, the curved thread structure not only enhances the structural strength of the pipeline, but also further optimizes the noise reduction effect, because sound waves will be reflected and scattered multiple times in the curved thread structure, thereby reducing the noise transmission efficiency.
[0010] Furthermore, a second noise reduction mechanism is arranged on the inner wall of the vertical pipeline. The second noise reduction mechanism includes a second spiral rib, and a first wave groove and a second wave groove are staggeredly arranged on the outer surface and the back of the second spiral rib.
[0011] By adopting the above technical solution, the second noise reduction mechanism provides an additional noise reduction layer. Through the staggered arrangement of the wave grooves, the reflection and scattering paths of sound waves in the pipeline are further increased, thereby improving the overall noise reduction effect.
[0012] Furthermore, a plurality of the first wave grooves and the second wave grooves are provided, and the plurality of the first wave grooves and the second wave grooves are arranged in a spiral array at equal intervals along the second spiral rib.
[0013] By adopting the above technical solution, the spiral array arrangement of the plurality of wave grooves enables sound waves to encounter more reflection surfaces in the pipeline, further dispersing the energy of the sound waves and improving the noise reduction performance.
[0014] Furthermore, a plurality of the first wave grooves and the second wave grooves and the second spiral rib form a wave thread structure.
[0015] By adopting the above technical solution, the wave thread structure not only enhances the structural stability of the pipeline, but also further optimizes the noise reduction effect through its complex shape, enabling sound waves to be more fully reflected and scattered in the pipeline.
[0016] Furthermore, an installation mechanism is arranged on the outer surface and the back of the vertical pipeline. The installation mechanism includes a flange ring, and a plurality of screw holes are provided on the flange ring.
[0017] By adopting the above technical solution, the arrangement of the installation mechanism facilitates the installation and disassembly of the pipeline. The presence of the flange ring and the screw holes enables the pipeline to be conveniently connected to other devices or pipelines, improving the flexibility and convenience of installation.
[0018] Furthermore, a protection mechanism is provided on the inner side of the two flange rings, and the protection mechanism includes two rotating shafts, and a first half sleeve and a second half sleeve are provided on the two rotating shafts.
[0019] By adopting the above technical solution, the setting of the protective mechanism provides an additional layer of protection for the pipeline, which can prevent external impact or vibration from damaging the pipeline. At the same time, the setting of the rotating shaft allows the protective mechanism to be easily opened and closed, which is convenient for inspection and maintenance of the pipeline.
[0020] Furthermore, a fixing plate is provided at the bottom of the first half sleeve and the second half sleeve, screw holes are opened on the fixing plate, and the fixing plate fixes the first half sleeve and the second half sleeve together by bolts.
[0021] By adopting the above technical solution, the setting of the fixed plate enhances the stability of the protective mechanism, and through the tightening action of the bolts, it ensures that the first half set and the second half set fit tightly on the pipeline, providing a reliable protective effect.
[0022] Furthermore, the first half and the second half are made of sound insulation cotton, and the outer surfaces of the first half and the second half are coated with a fire-proof coating.
[0023] By adopting the above technical solution, the use of sound insulation cotton further enhances the noise reduction effect of the pipeline, while the presence of the fire-proof coating improves the safety performance of the pipeline, which can prevent the occurrence of accidents such as fire to a certain extent and protect the safety of the pipeline and its surrounding environment.
[0024] In summary, the present invention has the following beneficial effects:
[0025] 1. The utility model provides a first noise reduction mechanism. Since the first noise reduction mechanism is provided on the inner wall of the vertical pipe, especially the first spiral rib with an arc-shaped groove, the energy of the water flow impact is effectively dispersed, and the noise generated by the direct collision between the water flow and the inner wall of the pipe is significantly reduced. The multiple arc-shaped grooves are arranged at equal intervals in a spiral array, which further enhances the noise reduction effect and enables the noise to be better absorbed and dissipated in the pipe. In addition, the provision of the curved thread structure not only enhances the noise reduction function, but also optimizes the fluid dynamics performance, reduces the resistance during fluid flow, improves the drainage efficiency, enables the water flow to pass through the pipe more smoothly, and reduces the energy consumption caused by the increase in flow resistance. At the same time, the provision of the first spiral rib and the arc-shaped groove thereon also enhances the structural strength of the pipe, improves the stability of the pipe when subjected to the impact of high-velocity or high-flow water flow, and reduces the additional noise generated by vibration.
[0026] 2. The utility model is provided with a second noise reduction mechanism, and the second noise reduction mechanism is arranged on the inner wall of the vertical pipeline. The second spiral rib with the first wave groove and the second wave groove is adopted to form a wave thread structure. This setting effectively disperses and absorbs the noise generated by the water flow impact, increases the reflection and scattering paths of the sound wave in the pipeline, significantly reduces the noise propagation. At the same time, the wave groove guides the water flow to flow along a stable path, reduces the turbulence and eddy current, reduces the additional noise generated by the unstable fluid flow, and helps to maintain the uniform distribution of the water flow, improving the drainage efficiency. In addition, the second spiral rib and its wave groove setting enhance the pipeline structure strength, make the pipeline more stable when bearing the water flow impact, reduce the vibration stress, and extend the service life. The wave thread structure also has good adaptability and can maintain a good noise reduction effect under different flow velocities and flow rates, improving the applicability and reliability of the equipment.
[0027] 3. The utility model is provided with a protection mechanism, and the protection mechanism is mainly composed of sound insulation materials or structures. For example, the first half set and the second half set made of sound insulation cotton can effectively absorb and isolate the noise, significantly enhancing the noise reduction effect. At the same time, these sound insulation materials can also buffer the external impact and vibration, protect the pipeline structure, extend the service life and reduce the maintenance cost. The setting of the protection mechanism is convenient for installation and disassembly, such as the way of connecting through a rotating shaft and fixing with bolts, improving the work efficiency. In addition, it may also include safety protection measures such as a fireproof coating to prevent accidents such as fires. The setting of the protection mechanism is flexible and can be adjusted according to different environments and requirements. For example, waterproof and anti-corrosion materials are selected in humid or corrosive environments. Finally, through the sound insulation materials coordinated with the pipeline material and color, the protection mechanism can also improve the overall aesthetic degree and achieve the combination of beauty and practicality.
