TECHNICAL FIELD
[0001] The utility model relates to a pipeline sand prevention technical field, concretely is a rainwater pipeline mouth sand prevention structure. BACKGROUND
[0002] In many areas, the sand weather is more frequent, and the sand particles in the sand weather can enter the rainwater pipeline system with the rainwater, for example, in the desert edge city or the construction site periphery, a large amount of sand dust is easily washed by rainwater, and the sand particles enter the pipeline and gradually accumulate at the bottom of the pipeline and the elbow, and with the lapse of time, the accumulated sand particles can reduce the effective water area of the pipeline.
[0003] In the prior art, a sedimentation tank is usually arranged in the pipeline to deposit the silt and prevent blockage, but in actual conditions, when the rainfall is large and the rainwater flow rate is too fast, the sand particles can be washed into the drainage pipeline before being deposited, and the high-speed water flow has a large kinetic energy, which can scour the deposits deposited at the bottom of the sedimentation tank when the water flow passes through the bottom of the sedimentation tank, especially near the water inlet and the water outlet, the impact force of the water flow is larger, if the deposits are scoured again, the deposits can enter the water flow again, increase the content of suspended solids in the water, and further reduce the purification effect of the sedimentation tank, therefore, the rainwater pipeline mouth sand prevention structure is provided. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a rainwater pipeline mouth sand prevention structure to solve the problems in the background art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a rainwater pipeline mouth sand prevention structure, comprising:
[0006] A pipeline and a grating plate arranged on the top of the pipeline.
[0007] A buffer assembly arranged in the pipeline, the buffer assembly comprising a first rotating shaft rotatably connected to the inner wall of the pipeline, a buffer plate rotatably connected to the first rotating shaft, a sliding groove formed on the side of the inner wall of the pipeline close to the buffer plate, a sliding block slidably connected in the sliding groove, a connecting rod connected to the sliding block, the connecting rod connected to the bottom of the buffer plate, and a spring fixedly connected between the bottom of the sliding block and the sliding groove, and a damper arranged in the spring.
[0008] A sedimentation tank is arranged in the pipeline, a clamping groove is formed on the side of the inner wall of the pipeline close to the sedimentation tank, and the sedimentation tank is arranged in the clamping groove.
[0009] Further, a quick release assembly is arranged on the side of the top of the pipeline close to the grating plate, the quick release assembly comprises a clamping seat, and a buckle is arranged on the side of the grating plate close to the clamping seat.
[0010] The above technical solution allows for the installation and removal of the grating plate by setting up quick-release components, facilitating the regular cleaning of silt and sand in the sedimentation tank inside the pipeline.
[0011] Furthermore, a filter assembly is provided inside the pipe on the side near the sedimentation tank. The filter assembly includes a filter plate, and a slide rail is provided on the inner wall of the pipe on the side near the filter plate.
[0012] By adopting the above technical solution, by setting up a filter plate, the tiny sand particles remaining in the rainwater can be further filtered out, effectively preventing sand particles from entering the drainage pipe.
[0013] Furthermore, a speed regulating component is provided inside the pipe near the filter plate. The speed regulating component includes a rotating rod with a paddle sleeved on it. A motor is provided on the pipe near the rotating rod, and a detector is provided on the pipe near the grid plate.
[0014] The above technical solution is adopted: by setting up a speed regulation component, when the detector detects that too much rainwater has accumulated inside, the motor is turned on to drive the blades to rotate. The backward force applied by the water flow will cause the water flow to gain forward acceleration, thereby increasing the flow rate.
[0015] Furthermore, a clamping assembly is provided on the side of the pipe near the detector. The clamping assembly includes a second rotating shaft, on which a torsion spring is provided, and a clamping plate is rotatably connected.
[0016] The above technical solution involves clamping and fixing the detector by setting up a clamping component.
[0017] Furthermore, a drain pipe is fixedly connected inside the pipe, the bottom of the pipe has an inclination angle of five degrees, the slope of the pipe is higher on the side closer to the first pivot, and the slope of the pipe is lower on the side closer to the drain pipe.
[0018] The above technical solution involves setting a slope to guide sediment into the sedimentation tank for settling, while rainwater flows into the drainage pipe.
[0019] Furthermore, the filter plate is slidably connected within the slide rail, and the slide rail is threadedly connected to the inner wall of the pipe with screws.
[0020] The above technical solution involves using screws to fix the slide rail and the filter plate inside the slide rail to the inside of the pipe.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a buffer component, the buffer plate can tilt under the action of gravity. This tilting motion can consume part of the kinetic energy of the rainwater. After the rainwater hits the buffer plate, it will disperse into water flow in different directions, thereby slowing down the overall flow rate of the rainwater. This solves the problem that in the prior art, most of the sedimentation tanks are set up inside the pipes to settle the silt and prevent blockage. However, in actual situations, when the rainfall is large and the rainwater flow rate is too fast, the sand particles may not have time to settle before being washed into the drainage pipe. Moreover, the high-speed water flow has a large kinetic energy. When it flows through the bottom of the sedimentation tank, it will have a scouring effect on the sediment that has already settled at the bottom. Especially near the inlet and outlet, the impact force of the water flow is greater. If the sediment is flushed up again, it will re-enter the water flow, increasing the suspended solids content in the water and further reducing the purification effect of the sedimentation tank.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figures 1-3 As shown, this utility model provides a technical solution: a sand-proof structure for a rainwater pipe inlet, comprising:
[0037] Pipe 1, and a grating plate 2 installed on top of pipe 1;
[0038] The buffer assembly 3 is placed inside the pipe 1. The buffer assembly 3 includes a first rotating shaft 31 rotatably connected to the inner wall of the pipe 1. A buffer plate 32 is rotatably connected to the first rotating shaft 31. A groove 33 is opened on the inner wall of the pipe 1 near the buffer plate 32. A slider 34 is slidably connected in the groove 33. A connecting rod 35 is connected to the slider 34. The connecting rod 35 is connected to the bottom of the buffer plate 32. A spring 36 is fixedly connected between the bottom of the slider 34 and the groove 33. A damping 37 is provided in the spring 36.
[0039] A sedimentation tank 8 is installed inside the pipe 1. A slot is provided on the side of the pipe 1 near the sedimentation tank 8, and the sedimentation tank 8 is located in the slot.
[0040] Specifically, when rainwater falls from the grating plate 2 into the pipe 1, it first contacts the buffer plate 32. The impact force exerted by the rainwater on the buffer plate 32 will cause the buffer plate 32 to tilt. During the tilting process, the slider 34 will slide downward in the groove 33. The spring 36 and the internal damping 37 can consume part of the kinetic energy of the rainwater. At the same time, after the rainwater hits the buffer plate 32, it will be dispersed into water flow in different directions, no longer in the original straight-line accelerated falling state, thereby slowing down the overall flow rate of the rainwater. Then it slowly flows into the sedimentation tank 8 to settle the mud and sand in the rainwater, preventing the rainwater flow rate from being too fast, and the sand particles may not have time to settle before being washed into the drain pipe 9.
[0041] Furthermore, such as Figure 1 As shown: A quick-release assembly 7 is provided on the top of the pipe 1 near the side of the grating plate 2. The quick-release assembly 7 includes a retainer 71. A buckle 72 is provided on the side of the grating plate 2 near the retainer 71. By setting the quick-release assembly 7, the grating plate 2 can be installed and removed, which facilitates the regular cleaning of the sludge in the sedimentation tank 8 inside the pipe 1.
[0042] The above solutions also have the problem that if the rainwater flow rate is too slow after the sedimentation process is completed, it may cause accumulation in pipe 1, leading to reduced drainage efficiency. Figure 1and Figure 2 As shown: A speed regulating component 4 is provided inside the pipe 1 near the filter plate 51. The speed regulating component 4 includes a rotating rod 41, on which a blade 42 is sleeved. A motor is provided on the side of the pipe 1 near the rotating rod 41. A detector 43 is provided on the side of the pipe 1 near the grid plate 2. A clamping component 6 is provided on the side of the pipe 1 near the detector 43. The clamping component 6 includes a second rotating shaft 61, on which a torsion spring 62 is provided. A clamping plate 63 is rotatably connected to the torsion spring 62. When the detector 43 detects that too much rainwater has accumulated inside, the motor is turned on to drive the blade 42 to rotate. The backward force applied by the water flow will cause the water flow to gain forward acceleration, thereby increasing the flow rate.
[0043] The above solutions also have the problem that the settled rainwater may still contain fine sand particles, such as... Figure 2 and Figure 4 As shown: A filter assembly 5 is installed inside the pipe 1 on the side near the sedimentation tank 8. The filter assembly 5 includes a filter plate 51. A slide rail 52 is installed on the inner wall of the pipe 1 on the side near the filter plate 51. The filter plate 51 is slidably connected in the slide rail 52. A screw 53 is threaded between the slide rail 52 and the inner wall of the pipe 1. By setting the filter plate 51, the tiny sand particles remaining in the rainwater can be further filtered out, effectively preventing sand particles from entering the drainage pipe.
[0044] Furthermore, such as Figure 2 As shown: Pipe 1 is fixedly connected to drain pipe 9. The bottom of pipe 1 is inclined at an angle of five degrees. The slope of pipe 1 is higher on the side closer to the first pivot 31 and lower on the side closer to drain pipe 9. By setting the slope, the sediment is guided to fall into the sedimentation tank 8 for sedimentation by gravity, while rainwater flows into the drain pipe 9.
[0045] The working principle of this utility model is as follows: When rainwater falls from the grating plate 2 into the pipe 1, it first contacts the buffer plate 32. The impact force exerted by the rainwater on the buffer plate 32 causes the buffer plate 32 to tilt. During the tilting process, the slider 34 slides downward in the groove 33. The spring 36 and the internal damping 37 can consume part of the kinetic energy of the rainwater. At the same time, after hitting the buffer plate 32, the rainwater will be dispersed into water flow in different directions, no longer falling in a straight line with acceleration, thereby slowing down the overall flow rate of the rainwater. Then, it slowly flows into the sedimentation tank 8 to settle the rainwater. The sediment in the water settles to prevent the rainwater from flowing too fast and the sand particles from being washed into the drain pipe 9 before settling. The slope is designed to guide the sediment to fall into the sedimentation tank 8 by gravity for settling. After settling, the rainwater will pass through the filter plate 51 to filter out the fine sediment. Then, when the detector 43 detects that too much filtered rainwater has accumulated, the motor is turned on to drive the paddle 42 to rotate. The backward force applied by the water flow will give the water flow forward acceleration, thereby increasing the flow rate and preventing accumulation in the pipe 1, which would reduce drainage efficiency. Finally, the rainwater is discharged from the drain pipe 9.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
