Description

Technical Field

[0001] The present invention belongs to the technical field of waterlogging treatment, and particularly relates to an efficient infiltration and drainage device for waterlogging treatment in urban villages. Background Art

[0002] In urban village areas, due to the relatively lagging infrastructure construction, the drainage system often has difficulty coping with extreme weather conditions such as heavy rainfall. During the rainy season, a large amount of rainwater mixed with domestic sewage, surface sediment, etc. quickly converges, resulting in frequent waterlogging problems. Waterlogging not only seriously affects the daily life of residents, but may also cause damage to housing buildings, road traffic, etc., and even threaten the life and property safety of residents.

[0003] In the prior art, when the drainage facilities face these complex water flows, the filtering function is very limited. For example, a drainage well (with a manhole cover at the top of the wellbore, the manhole cover is porous and covered with a filter screen) can block some larger debris, but it cannot effectively intercept fine sediment, garbage fragments and other impurities in the sewage. These impurities enter the drainage pipeline along with the water flow and gradually accumulate on the inner wall of the pipeline, resulting in a smaller pipeline diameter and a slower water flow velocity, ultimately causing the drainage system to be blocked, and further leading to a significant decline in the drainage capacity again. In addition, in terms of maintenance after blockage, it requires a large amount of manpower and material resources, and the practicability is poor. Summary of the Invention

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Please also refer to Figure 1 and Figure 2, the efficient infiltration and drainage device for urban village waterlogging treatment provided by the present invention will be described below. The efficient infiltration and drainage device for urban village waterlogging treatment includes a fixed base 10, a cylinder 20, a filter screen cylinder 30, a cleaning component 40, and a porous drainage pipe 50. The fixed base 10 can be fixedly installed in a drainage well. A drainage structure 60 is provided at the bottom of the fixed base 10. The cylinder 20 is fixedly arranged at the top of the fixed base 10 and has a cylinder cavity 21 with an axis arranged in the vertical direction. A water guide pipe 22 communicating the cylinder cavity 21 and the drainage structure 60 is provided at the bottom of the cylinder 20. The filter screen cylinder 30 is coaxially arranged in the cylinder cavity 21, and an annular cavity is formed between the filter screen cylinder 30 and the cylinder 20. The cleaning component 40 is rotatably arranged on the cylinder 20. The cleaning component 40 has a cleaning part located inside the filter screen cylinder 30 and in contact with the inner wall of the filter screen cylinder 30, and also has a stirring part located at the bottom of the filter screen cylinder 30 and extending into the annular cavity. A plurality of porous drainage pipes 50 are provided, and each porous drainage pipe 50 is arranged outside the cylinder 20, and each porous drainage pipe 50 is communicated with a water inlet hole provided on the side wall of the cylinder 20.

[0019] Among them, the filter screen cylinder 30 filters the seepage water entering the annular cavity from each porous drainage pipe 50 and guides it into the water guide pipe 22. The impurities accumulated at the bottom of the annular cavity are disturbed by the stirring part and discharged through a sewage outlet 23 provided at the bottom of the annular cavity.

[0020] For the efficient infiltration and drainage device for urban village waterlogging treatment provided in this embodiment, compared with the prior art, the fixed base 10 can ensure being fixedly arranged in the drainage well to provide a carrier platform. The filter screen cylinder 30 in the cylinder 20 and the cylinder 20 enclose an annular cavity, which can ensure filtering the water introduced by the porous drainage pipes 50. The filtered rainwater enters the drainage structure 60 through the water guide pipe 22. At the same time, the filter screen cylinder 30 leaves the filtered impurities in the annular cavity, thus preventing the impurities from entering the sewer and further avoiding the blockage of the sewer. The provided cleaning component 40 can ensure cleaning the inner wall of the filter screen cylinder 30 inside the filter screen cylinder 30, preventing the mesh holes of the filter screen cylinder 30 from being blocked, and further ensuring the stability of filtration. The cleaning component 40 is also connected to the stirring part, and the stirring part can stir the accumulated impurities at the bottom of the annular cavity, thus preventing the accumulation of impurities at the bottom of the annular cavity and further ensuring the filtration effect. The porous drainage pipes 50 can perform primary filtration to prevent larger impurities from entering the annular cavity, and to a certain extent, it can also prevent the sewer from being blocked.

[0021] In this embodiment, regarding the fixed base 10, in addition to being arranged in the drainage well, it can of course also be arranged in other drainage facilities where the road surface is connected to the sewer. During use, each porous drainage pipe 50 can be located on the road surface. In addition, the sewage outlet 23 can be connected to a pressure conveying module, which can regularly export this part of the impurities. The pressure conveying module can ensure the conveying pipeline and the conveying pump.

[0022] In addition, when the diameter of the drainage well is large, an inflatable rubber ring can be provided on the outer periphery of the cylinder 20, and the inflatable rubber ring can fill the gap between the cylinder 20 and the drainage well.

[0023] In some embodiments, the cleaning assembly 40 may be configured as follows: Figure 2 and Figure 3 The structure shown. Figure 2 and Figure 3 The cleaning assembly 40 includes a rotating ring 41, an adjusting shaft 42, a transverse connecting frame 43, a vertical rod 44 and a toggle block 45. The rotating ring 41 is rotatably set at the bottom of the cylinder cavity 21, and the rotating axis is colinear with the axis of the cylinder cavity 21. The top of the rotating ring 41 is in sliding contact with the annular edge at the bottom end of the filter cylinder 30. The adjusting shaft 42 is rotatably set on the cylinder 20 and is coaxially arranged with the rotating ring 41. The top of the adjusting shaft 42 extends out of the cylinder 20. A hand-operated wheel is provided at the end of the adjusting shaft 42 extending out of the cylinder 20. The transverse connecting frame 43 is horizontally set in the filter cylinder 30 and is fixedly connected to the adjusting shaft 42. There are multiple vertical rods 44, and each vertical rod 44 is arranged at an annular interval around the axis of the rotating ring 41. The top of each vertical rod 44 is connected to the transverse connecting frame 43, and the bottom end is connected to the rotating ring 41. Each vertical rod 44 is equipped with a brush 46 that contacts the inner wall of the filter cylinder 30. The brushes 46 combine to form a cleaning section. Multiple toggle blocks 45 are provided. These toggle blocks 45 are annularly spaced around the axis of the rotating ring 41 and are fixed to the outer wall of the rotating ring 41. Each toggle block 45 extends into the annular cavity. The combination of these toggle blocks 45 forms an agitating section.

[0024] Specifically, after rainfall, the adjustment shaft 42 can be rotated by the hand wheel, which drives the horizontal connecting frame 43 to rotate. This in turn drives the rotating ring 41 to rotate via the vertical rods 44, ensuring that the brushes 46 on each vertical rod 44 clean the inner wall of the filter cylinder 30, thereby preventing the mesh of the filter cylinder 30 from clogging and ensuring continued good filtration. The rotating ring 41 is rotatably connected to the bottom of the cylinder cavity 21. When the rotating ring 41 rotates, it can drive the toggle blocks 45 to stir the bottom of the annular cavity, thereby ensuring that accumulated impurities are disturbed and easily discharged through the sewage outlet 23.

[0025] In this embodiment, the rotating ring 41 has a certain height, and the annular edge at its top is in sliding contact with the annular edge at the bottom of the filter screen cylinder 30, that is, the filter screen cylinder 30 and the rotating ring 41 jointly separate the cylinder cavity 21, thereby ensuring that the filtered rainwater enters the drainage structure 60 through the water pipe 22.

[0026] By setting up the cleaning component 40, the filtering effect of the filter mesh cylinder 30 on rainwater can be effectively guaranteed, and impurities can be prevented from entering the sewer and causing blockage of the sewer, which is highly practical.

[0027] It should be noted that two transverse connecting frames 43 may be provided, and the other transverse connecting frame 43 is located in the rotating ring 41 to ensure that the adjusting shaft 42 is fixedly connected to the rotating ring 41 and enhance the structural strength.

[0028] In some embodiments, the toggle block 45 may be configured as follows: Figure 2 The structure shown. Figure 2 Each toggle block 45 is provided with a vertical auxiliary plate 47 extending toward the top of the annular cavity, and the top of each auxiliary plate corresponds to each water inlet. Each porous seepage pipe 50 is arranged along the tangential direction of the cylinder 20.

[0029] In the process of heavy rainfall, it is not convenient to manually adjust the hand wheel. At this time, the amount of water entering the annular cavity through the porous seepage pipe 50 increases, and the porous seepage pipe 50 is arranged along the tangential direction of the cylinder 20, which can ensure that the incoming water flow also enters along the tangential direction of the cylinder 20, and then impacts each vertical auxiliary plate 47, causing each vertical auxiliary plate 47 to rotate, and then causing the cleaning component 40 to rotate. This method can effectively ensure automatic cleaning and ensure the filtering effect.

[0030] In some embodiments, the water pipe 22 may be Figure 3 The structure shown. Figure 3 The inner diameter of the water pipe 22 is smaller than the inner diameter of the rotating ring 41. This structure can ensure the stable rotation connection of the rotating ring 41.

[0031] In some embodiments, the fixed base 10 may be a Figures 4 to 7 The structure shown. Figures 4 to 7 The fixed base 10 includes a fixing ring 11, a support ring 12, a guide column 13 and a support assembly 14. The fixing ring 11 is fixedly connected to the cylinder 20. The support ring 12 is located below the fixing ring 11 and is arranged parallel to the fixing ring 11. The support ring 12 has a sliding hole for the water pipe 22 to pass through. The bottom end of the support ring 12 is fixedly connected to the drainage structure 60. There are multiple guide columns 13, and each guide column 13 is arranged at an annular interval around the axis of the fixing ring 11. The top end of each guide column 13 is fixedly connected to the fixing ring 11, and the bottom end extends vertically downward and passes through the support ring 12. There are multiple support assemblies 14, and each support assembly 14 is arranged at an annular interval around the axis of the fixing ring 11. Each support assembly 14 is connected to the fixing ring 11 and the support ring 12. Each support assembly 14 has an abutment portion that can extend radially along the fixing ring 11.

[0032] When the support ring 12 moves closer to the fixed ring 11 , each support assembly 14 drives the corresponding abutting portion to abut against the inner wall of the drainage well.

[0033] During use, the support ring 12 can be fixed first, and then the fixing ring 11 will move closer to the support ring 12 under the action of gravity. At this time, restricted by the guiding columns 13, the fixing ring 11 moves in a directional manner. After the fixing ring 11 corresponds to the support ring 12, each support component 14 is pushed, and then the abutting parts in each support component 14 extend outwards and abut against the inner wall of the drainage well to achieve fixation with the drainage well.

[0034] This structure can ensure that the fixed base 10 is fixed in any drainage well, and can be conveniently connected to ensure the stability during the rainwater filtration process.

[0035] In some embodiments, the above-mentioned support component 14 can adopt the structure as Figures 4 to 7 shown. Refer to Figures 4 to 7 , each support component 14 includes a first connecting rod 141, a second connecting rod 142 and an abutting rod 143. One end of the first connecting rod 141 is rotatably connected to the fixing ring 11. One end of the second connecting rod 142 is rotatably connected to the support ring 12, the midpoint of the second connecting rod 142 is rotatably connected to the midpoint of the first connecting rod 141, and the second connecting rod 142 and the first connecting rod 141 form a scissor-type telescopic structure. The abutting rod 143 is arranged vertically, the bottom end is rotatably connected to the other end of the first connecting rod 141, and the top end has a limiting chute for the other end of the second connecting rod 142 to slide. The abutting rod 143 is the abutting part.

[0036] The first connecting rod 141 and the second connecting rod 142 form a scissor-type telescopic structure, which can drive the abutting rod 143 to extend outwards and abut against the inner wall of the drainage well during the process of the support ring 12 moving closer to the fixing ring 11. The structure is simple, the linkage cavity is formed, and it is easy to control, ensuring the fixing effect with the inner wall of the drainage well.

[0037] In some embodiments, the above-mentioned support ring 12 can adopt the structure as Figure 4 shown. Refer to Figure 4 , a plurality of limiting plates 16 are arranged on the outer wall of the support ring 12 in a surrounding manner, and each limiting plate 16 is rotatably arranged on the support ring 12. A plurality of accommodating grooves for accommodating each limiting plate 16 are arranged on the outer wall of the support ring 12. This structure can adapt to the situation where there is an annular platform in the drainage well, and the support ring 12 can be directly erected through a plurality of limiting plates 16 to further ensure the connection process.

[0038] In addition, guy ropes can be arranged on the support ring 12. There are multiple guy ropes, and the guy ropes are arranged at annular intervals around the axis of the support ring 12. The other ends of the guy ropes extend upward and pass through the collar provided at the top end of the cylinder 20. A damping bolt is provided on the collar. The damping bolt is arranged along the radial direction of the collar and can abut and fix the guy ropes inside the collar. When there is no annular platform inside the drainage well, by pulling each guy rope, the support ring 12 can be moved closer to the fixed ring 11, so as to realize the abutting and fixing of each support component 14 against the inner wall of the drainage well.

[0039] In some embodiments, the above-mentioned fixed base 10 can adopt the structure as Figures 7 and 8 shown. Refer to Figures 7 and 8 , the fixed base 10 further includes auxiliary support components 14. There are multiple auxiliary components, and each auxiliary support component 14 is arranged at annular intervals around the axis of the support ring 12 and corresponds to each guide post 13 one by one. Each auxiliary support component 14 includes a vertical bottom plate 151, a turning rod 152 and a pull rod 153. The top end of the vertical bottom plate 151 is fixedly connected to the support ring 12. The turning rod 152 has a first end of the turning rod 152 and a second end of the turning rod 152. An extension rod is fixedly connected to the turning rod, and the extension rod is perpendicular to the turning rod 152 and is located between the first end of the turning rod 152 and the second end of the turning rod 152. The end of the extension rod is the third end of the turning rod 152. The third end of the turning rod 152 is rotatably connected to the bottom end of the vertical bottom plate 151. The top end of the pull rod 153 is rotatably connected to the corresponding guide post 13, and the bottom end is rotatably connected to the first end of the turning rod 152.

[0040] Among them, as the support ring 12 moves closer to the fixed ring 11, the pull rod 153 pushes the first end of the turning rod 152, so that the second end of the turning rod 152 rotates upward in a pitching motion and unfolds outward from the support ring 12.

[0041] In order to further increase the fixing stability of the fixed base 10 and the inner wall of the drainage well, during the process of the support ring 12 moving relatively closer to the fixed ring 11, each limiting post moves downward relative to the support ring 12, and then will push each pull rod 153. The pull rod 153 then pushes the first end of the turning rod 152, so that the second end of the turning rod 152 rotates upward in a pitching motion, realizing the unfolding of the turning rod 152, and making the second end of the turning rod 152 abut against the inner wall of the drainage well, further improving the fixing effect with the inner wall of the drainage well, ensuring the fixing stability, and effectively avoiding impurities in the rainwater from entering the sewer.

[0042] In this embodiment, each pull rod 153 is inclined. The top end of each pull rod 153 is rotatably connected to the bottom end of the corresponding guide post 13, and the bottom end can extend obliquely in the direction of the axis of the support ring 12 to ensure that the second ends of the turning rods 152 can be turned upward and outward in a pitching motion.

[0043] In some embodiments, the above-mentioned drainage structure 60 can adopt the structure as Figure 9 The structure shown. Refer to Figure 9 , the drainage structure 60 includes a sleeve 61, a plugging cover 62 and a tension spring 63. The sleeve 61 is fixedly connected to the bottom end of the support ring 12 and is coaxially arranged with the support ring 12. The sleeve 61 is for the sliding connection of the water guide pipe 22. The plugging cover 62 is rotatably connected to the bottom end of the sleeve 61. One end of the tension spring 63 is connected to the plugging cover 62, and the other end is connected to a hook arranged on the inner wall of the sleeve 61. The tension spring 63 can continuously pull the plugging cover 62 to keep the cover having a tendency to be buckled on the bottom port of the sleeve 61.

[0044] The arranged drainage structure 60 can ensure that when there is more water inside the sleeve 61, the water pushes the plugging plate to open under the action of gravity, and then flows into the sewer. Of course, the plugging plate is connected with a tension spring 63, and it can also prevent the water in the sewer from flowing back into the sleeve 61 when the water volume in the sewer is large, thereby avoiding situations such as waterlogging. The structure is simple and has strong practicability.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
