Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, and more specifically, to a low-noise drainage pipeline. Background Art

[0002] Drainage pipes, as one of the common drainage equipment in municipal construction, can transport water smoothly through them, making it convenient for centralized sewage treatment.

[0003] Publication No. CN215891442U discloses an insulation pipe noise reduction structure, including a pipe substrate, the outside of the pipe substrate is coated with a heat insulation layer, the outer surface of the heat insulation layer is wrapped with an airbag reflective layer, the outside of the airbag reflective layer is coated with a sound insulation layer, and the outside of the sound insulation layer is covered with an anti-corrosion layer.

[0004] The above technical solution can isolate the heat from the inside of the pipe through the thermal insulation layer, and can reflect and absorb the noise from the inside of the pipe through the airbag reflective layer and the sound insulation layer, thereby greatly reducing the noise level of the outer layer of the pipe without affecting the thermal insulation effect of the pipe, thereby improving the noise reduction effect of the pipe. However, in the above technical solution, when water passes through the pipe, the water will impact the inner wall of the pipe, causing the pipe to vibrate, and the above technical solution does not provide a structure for shock absorbing the pipe in the pipe, which causes the pipe to make a humming sound due to vibration, affecting the noise reduction effect of the pipe.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a low-noise drainage pipe, which solves the problem that when water passes through the pipe, the water will impact the inner wall of the pipe, causing the pipe to vibrate, making the pipe emit a humming sound due to the vibration, thereby affecting the noise reduction effect of the pipe.

[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a low-noise drainage pipe, including a pipe body, a plurality of guide plates are fixedly connected to the inner wall of the pipe body, the guide plates are spiral-shaped and there is a spacing between adjacent guide plates, a connecting plate is fixedly connected to the top of the guide plates, a driving component for driving water to flow along the guide plates is provided in the pipe body, and a noise reduction component for reducing noise is provided on the pipe body.

[0008] By adopting the above technical solution, when water enters the pipe body, the water will contact the side wall of the connecting plate, and then the water will start to flow along the side wall of the connecting plate to the spacing between the guide plates. At the same time, through the driving component, the water can be driven to flow along the side walls of the guide plates. By using the spiral arrangement of the guide plates, the water can flow in a spiral shape along the inner wall of the pipe body, thereby reducing the mutual impact between the water and the inner wall of the pipe body, reducing the vibration of the pipe body caused by the collision, and then reducing the humming sound of the pipe body due to the vibration, thereby improving the noise reduction effect of the pipe body. At the same time, through the arrangement of the noise reduction component, the noise reduction effect of the pipe body can be further improved, and the vibration of the pipe body can be buffered, thereby improving the seismic effect of the pipe body.

[0009] The utility model is further configured as follows: the driving assembly includes a limiting rod fixedly connected to a connecting plate close to a side of the guide plate, the side wall of the limiting rod and a plurality of side walls of the guide plates fit together, a guide block is detachably connected to the connecting plate, the guide block is inclined and there is a gap between the guide block and the inner side wall of the pipeline body.

[0010] By adopting the above technical solution, when water enters the pipe body, the water will contact the guide block on the connecting plate, and at the same time, the water will flow around along the inclined surface of the guide block. By setting the inclined surface of the guide block, it can not only guide the water, but also reduce the impact force of the water on the pipe body, reduce the flow rate of the water, and reduce the impact of the water on the pipe body. When the water moves along the inclined surface of the guide block, the water will flow into the side walls of the guide plates through the gap between the guide block and the pipe body. At this time, by setting the limiting rod, it can be avoided that the water is separated from the guide plates when flowing, thereby achieving the effect of driving the water to move along the side walls of the guide plates.

[0011] The utility model is further configured as follows: the noise reduction component comprises a protective cover fixedly connected to the outer side wall of the pipeline body, a plurality of support plates are fixedly connected inside the protective cover, and a sponge layer is fixedly connected between the plurality of support plates.

[0012] By adopting the above technical solution, when the pipeline body emits a buzzing sound due to vibration, the buzzing sound can be reduced by setting the sponge layer and utilizing the several holes inside the sponge layer, thereby improving the noise reduction effect of the pipeline body. At the same time, since the sponge layer has good flexibility, when the pipeline body transmits the vibration to the sponge layer, the sponge layer can vibrate to have a buffering effect, and by setting the support plate, the structural strength inside the protective cover can be further improved, thereby improving the stability of the protective cover.

[0013] The utility model is further configured as follows: one of the sponge layers and the outer side wall of the pipeline body are in contact with each other.

[0014] By adopting the above technical solution, the position of the sponge layer can be further limited, thereby improving the noise reduction and shock absorption effects of the pipeline body.

[0015] The utility model is further configured as follows: a cavity is provided inside the guide block, a connecting rod is fixedly connected to the connecting plate, the connecting rod penetrates into the cavity, two fixing rods are fixedly connected in the cavity, a clamping block is rotatably connected to the two fixing rods, an annular groove for clamping the clamping block is provided on the side wall of the connecting rod, the clamping block and the fixing rod are connected by a torsion spring, and when the torsion spring is in a natural state, the clamping block and the annular groove are clamped with each other, and a driving member for driving the clamping block to rotate is provided on the guide block.

[0016] By adopting the above technical solution, when the guide block needs to be installed, the two clamping blocks are driven to start rotating by the driving member. At this time, the torsion spring begins to deform due to the rotation of the two clamping blocks, and then the connecting rod is inserted into the cavity of the guide block. Then, the restriction on the clamping block is cancelled again by the driving member. At this time, the torsion spring begins to recover and drives the clamping block and the annular groove to engage with each other. At this time, the guide block is restricted by the clamping block and the annular groove, so that the guide block cannot be separated from the connecting plate, thereby completing the installation of the guide block. When the guide block needs to be disassembled, it is only necessary to drive the two clamping blocks to rotate by the driving member to drive the two clamping blocks and the annular groove to separate from each other. At this time, the restriction between the guide block and the fixed rod is lost, and the guide block and the connecting plate can be driven to separate from each other, thereby achieving the effect of disassembling the guide block.

[0017] The utility model is further configured as follows: the driving member includes two through holes opened on the guide block, and a pressing sheet is fixedly connected to the two through holes. The pressing sheet has elastic deformation capability, and the two clamping blocks are always in contact with the side walls of the pressing sheet.

[0018] By adopting the above technical solution, when driving the two blocks to rotate, pressure is applied to the pressing plate, driving the pressing plate to begin to deform in the direction of the block, and at the same time the block begins to rotate under the influence of the pressing plate, thereby achieving the effect of driving the block to rotate without affecting the normal use of the guide plate.

[0019] The utility model is further configured that: when the clamping block and the annular groove are clamped with each other, the two pressing pieces protrude outwards.

[0020] By adopting the above technical solution, it is possible to easily drive the pressing piece to drive the card block to rotate, which is convenient for users to operate.

[0021] The utility model is further configured as follows: a filter screen is fixedly connected to the side wall of the guide block, and the side wall of the filter screen and the inner side wall of the pipeline body are fitted to each other.

[0022] By adopting the above technical solution, impurities contained in the water can be filtered, and at the same time the flow rate of the water can be reduced, thereby reducing the impact force of the water on the side wall of the pipeline body.

[0023] In summary, the utility model has the following beneficial effects: when water enters the pipe body, the water will start to flow along the side wall of the connecting plate toward the spacing between the guide plates, and at the same time, through the driving component, the water can be driven to flow along the side walls of the guide plates. By utilizing the spiral arrangement of the guide plates, the water can flow in a spiral shape along the inner wall of the pipe body, thereby reducing the mutual impact between the water and the inner wall of the pipe body, reducing the vibration of the pipe body caused by the collision, and then reducing the humming sound of the pipe body caused by the vibration, thereby improving the noise reduction effect of the pipe body, and at the same time, through the arrangement of the noise reduction component, the noise reduction effect of the pipe body can be further improved, and the vibration of the pipe body can be buffered, thereby improving the seismic effect of the pipe body.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] A low noise drainage pipe, such as Figure 1-Figure 4 As shown, it includes a pipe body 1, a plurality of guide plates 2 are fixedly connected to the inner side wall of the pipe body 1, the plurality of guide plates 2 are spiral-shaped and there is a spacing between two adjacent guide plates 2, a connecting plate 3 is fixedly connected to the top of the plurality of guide plates 2, a driving component for driving water to flow along the plurality of guide plates 2 is provided in the pipe body 1, and a noise reduction component for reducing noise is provided on the pipe body 1. When water enters the pipe body 1, the water contacts the side wall of the connecting plate 3, and then the water starts to flow along the side wall of the connecting plate 3 toward the spacing between the plurality of guide plates 2, and at the same time, the driving component The component can drive water to flow along the side walls of the guide plates 2. The spiral arrangement of the guide plates 2 can make the water flow in a spiral shape along the inner wall of the pipe body 1, thereby reducing the mutual impact between the water and the inner wall of the pipe body 1, reducing the vibration of the pipe body 1 caused by the collision, and thus reducing the humming sound of the pipe body 1 due to the vibration, thereby improving the noise reduction effect of the pipe body 1. At the same time, through the arrangement of the noise reduction component, the noise reduction effect of the pipe body 1 can be further improved, and the vibration of the pipe body 1 can be buffered, thereby improving the seismic effect of the pipe body 1.

[0033] like Figure 1-Figure 4As shown, the driving assembly includes a limiting rod 4 fixedly connected to the side of the connecting plate 3 close to the guide plate 2, the side wall of the limiting rod 4 and the side walls of the guide plates 2 are fitted together, and the connecting plate 3 is detachably connected with a guide block 5, which is inclined and there is a gap between the guide block 5 and the inner side wall of the pipe body 1. When water enters the pipe body 1, the water will contact the guide block 5 on the connecting plate 3, and the water will flow around along the inclined surface of the guide block 5. Through the setting of the inclined surface of the guide block 5, it can guide the water while reducing the impact force on the pipe body 1, reduce the flow rate of the water, and reduce the impact of the water on the pipe body 1. When the water moves along the inclined surface of the guide block 5, the water will flow into the side walls of the guide plates 2 through the gap between the guide block 5 and the pipe body 1. At this time, through the setting of the limiting rod 4, it can be prevented that the water is separated from the guide plates 2 when flowing, so as to achieve the effect of driving the water to move along the side walls of the guide plates 2.

[0034] like Figure 1-Figure 4 As shown, the noise reduction component includes a protective cover 6 fixedly connected to the outer wall of the pipe body 1, a plurality of support plates 7 are fixedly connected inside the protective cover 6, and a sponge layer 8 is fixedly connected between the plurality of support plates 7. When the pipe body 1 emits a humming sound due to vibration, the humming sound can be reduced by setting the sponge layer 8 and utilizing a plurality of holes inside the sponge layer 8, thereby improving the noise reduction effect of the pipe body 1. At the same time, since the sponge layer 8 has good flexibility, when the pipe body 1 transmits vibration to the sponge layer 8, the sponge layer 8 can vibrate and have a buffering effect. In addition, by utilizing the setting of the support plates 7, the structural strength inside the protective cover 6 can be further improved, and the stability of the protective cover 6 can be improved. The sponge layer 8 and the outer wall of the pipe body 1 fit together, which can further limit the position of the sponge layer 8 and improve the noise reduction and shock absorption effects of the pipe body 1.

[0035] like Figure 1-Figure 4 As shown, a cavity 9 is provided inside the guide block 5, a connecting rod 10 is fixedly connected to the connecting plate 3, the connecting rod 10 penetrates into the cavity 9, two fixed rods 11 are fixedly connected in the cavity 9, a clamping block 12 is rotatably connected to the two fixed rods 11, an annular groove 13 for clamping the clamping block 12 is provided on the side wall of the connecting rod 10, the clamping block 12 and the fixed rod 11 are connected by a torsion spring 14, when the torsion spring 14 is in a natural state, the clamping block 12 and the annular groove 13 are clamped with each other, a driving member for driving the clamping block 12 to rotate is provided on the guide block 5, and the driving member includes two through holes 15 provided on the guide block 5, a pressing plate 16 is fixedly connected to the two through holes 15, the pressing plate 16 has elastic deformation ability, and the two clamping blocks 12 are always in contact with the side walls of the pressing plate 16.

[0036] When the guide block 5 needs to be installed, pressure is applied to the pressing piece 16 to drive the pressing piece 16 to begin to deform in the direction of the block 12. At the same time, the block 12 begins to rotate under the influence of the pressing piece 16. At this time, the torsion spring 14 begins to deform under the influence of the rotation of the two blocks 12. Subsequently, the connecting rod 10 is inserted into the cavity 9 of the guide block 5, and then pressure is applied to the pressing piece 16 again to drive the pressing piece 16 to begin to deform in the direction of the block 12 and drive the block 12 to rotate. At this time, the torsion spring 14 begins to recover its deformation and drives the block 12 and the annular groove 13 to engage with each other. At this time, the guide block 5 is affected by the block 12. The restriction of the annular groove 13 makes it impossible for the guide block 5 to be separated from the connecting plate 3, thereby completing the installation of the guide block 5. When the guide block 5 needs to be disassembled, it is only necessary to drive the two clamping blocks 12 to rotate through the driving member to drive the two clamping blocks 12 and the annular groove 13 to separate from each other. At this time, the restriction between the guide block 5 and the fixing rod 11 is lost, and the guide block 5 and the connecting plate 3 can be driven to separate from each other, thereby achieving the effect of disassembling the guide block 5. When the clamping block 12 and the annular groove 13 are engaged with each other, the two pressing pieces 16 protrude outward, which can facilitate the pressing piece 16 to drive the clamping block 12 to rotate, which is convenient for the user to operate.

[0037] like Figure 1-Figure 4 As shown, a filter screen 17 is fixedly connected to the side wall of the guide block 5. The side wall of the filter screen 17 and the inner wall of the pipe body 1 fit together, which can filter impurities contained in the water and reduce the flow rate of the water, thereby reducing the impact force of the water on the side wall of the pipe body 1.

[0038] The utility model is used as follows during normal use: when water enters the pipe body 1, the water will contact the side walls of the connecting plate 3, and then the water will begin to flow along the side walls of the connecting plate 3 to the spacing between the guide plates 2, and at the same time, the water will contact the guide blocks 5 on the connecting plate 3, and at the same time, the water will flow around along the inclined surface of the guide blocks 5, and flow into the side walls of the guide plates 2 through the gap between the guide blocks 5 and the pipe body 1, and then the water will be driven to flow along the side walls of the guide plates 2. By utilizing the spiral arrangement of the guide plates 2, the water can flow in a spiral shape along the inner wall of the pipe body 1, thereby reducing the mutual impact between the water and the inner wall of the pipe body 1, reducing the vibration of the pipe body 1 caused by the collision, and then reducing the humming sound of the pipe body 1 due to the vibration, thereby improving the noise reduction effect of the pipe body 1.

[0039] When the pipe body 1 makes a humming sound due to vibration, the humming sound can be reduced by setting the sponge layer 8 and utilizing the several holes inside the sponge layer 8, thereby improving the noise reduction effect of the pipe body 1. At the same time, since the sponge layer 8 has good flexibility, when the pipe body 1 transmits the vibration to the sponge layer 8, the sponge layer 8 can vibrate and have a buffering effect. In addition, by using the support plate 7, the structural strength inside the protective cover 6 can be further improved, and the stability of the protective cover 6 can be improved, thereby improving the noise reduction effect of the pipe body 1, and can also buffer the vibration received by the pipe body 1, thereby improving the seismic resistance of the pipe body 1.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
