Description

Technical Field

[0001] This application relates to the field of municipal drainage, and particularly to a rainwater drainage regulation system for sponge cities. Background Art

[0002] A sponge city is a new generation of urban rain and flood management concept, which means that the city can be like a sponge and has good elasticity in adapting to environmental changes and coping with natural disasters brought by rainwater, and can also be called a "water elastic city".

[0003] During rainfall, rainwater on the ground will flow into drainage facilities such as drainage ditches and drainage pipe networks, and then the drainage facilities will guide the rainwater through the filter plate to reduce the sediment content in the rainwater. The filtered rainwater is discharged into the water storage tank for collection. The water inside the water storage tank can be pumped to the water purification plant for purification, or the water in the water storage tank can be taken out for irrigating the green plants on the road during drought.

[0004] Regarding the above related technologies, the inventor believes that after the rainwater is filtered by the filter plate, the sediment will remain on the filter plate. When the rainfall is large and lasts for a long time, the amount of rainwater filtered by the filter plate is also large, which increases the sediment on the filter plate and may cause the filter plate to become clogged. Summary of the Invention

[0005] In order to reduce the occurrence of filter plate clogging, this application provides a rainwater drainage regulation system for sponge cities.

[0006] A rainwater drainage regulation system for sponge cities provided by this application adopts the following technical solutions:

[0007] A rainwater drainage regulation system for sponge cities includes a filter box and a water storage tank. An inlet pipe is fixedly installed on the top side of the filter box, a water collection tank is fixedly installed on one side wall of the filter box, a drain pipe is fixedly installed between the bottom side of the water collection tank and the top side of the water storage tank, an outlet pipe is fixedly installed on one side wall of the water storage tank, a valve is fitted to the outlet pipe, an installation opening is formed on the side of the filter box close to the water collection tank, a filter plate is fixedly installed inside the installation opening, a lifting plate is arranged inside the filter box, the peripheral side wall of the lifting plate abuts against the inner side wall of the filter box, a brush is fixedly installed on the top surface of the lifting plate, the brush abuts against the filter plate, and a lifting mechanism is installed on the lifting plate, and the lifting mechanism is used to drive the lifting plate to move up and down.

[0008] By adopting the above technical solutions, during rainfall, rainwater flows into the filter box from the inlet pipe, and the rainwater inside the filter box flows into the water collection tank after being filtered by the filter plate. The rainwater inside the water collection tank flows into the water storage tank through the drain pipe for collection. When it is necessary to take out the rainwater from the water storage tank, the valve is opened, so that the rainwater inside the water storage tank is discharged from the outlet pipe.

[0009] When it is raining, if the filter plate becomes blocked, the lifting plate is driven to rise and fall by the lifting mechanism. When the lifting plate rises and falls, it drives the brush to scrape the sediment on the filter plate, thereby reducing the occurrence of blockage of the filter plate.

[0010] Optionally, the lifting mechanism includes a water storage tank, a suspension rope, a first fixed pulley, a second fixed pulley, a support rod and a blocking plate. The top side of the water storage tank has an opening. The water storage tank is located inside the water collection tank. The peripheral side wall of the water storage tank abuts against the inner side wall of the water collection tank. The first fixed pulley is fixedly installed on the top side of the water collection tank. The second fixed pulley is fixedly installed on the top side of the filter tank. One end of the suspension rope is fixedly connected to the top side of the water storage tank. The other end of the suspension rope is fixedly installed on the top surface of the lifting plate. The suspension rope passes through the top sides of the water collection tank and the filter tank. The suspension rope is wound around the first fixed pulley and the second fixed pulley. A drain port is opened at the bottom side of the water storage tank. The support rod passes through the drain port. One end of the support rod is fixedly connected to the inner bottom wall of the water collection tank. The other end of the support rod is fixedly connected to the blocking plate. The blocking plate is used to block the drain port.

[0011] By adopting the above technical solution, when the filter plate is blocked, the speed of rainwater passing through the filter plate decreases, so that rainwater accumulates inside the filter tank. After the rainwater accumulates on the lifting plate, the lifting plate moves downward, so that the brush cleans the filter plate. At the same time, the lifting plate drives the water storage tank to move upward through the first fixed pulley, the second fixed pulley and the suspension rope. After the water storage tank rises to a certain height, the blocking plate seals the drain port, so that rainwater accumulates inside the water storage tank. The weight of the water storage tank increases, so that the water storage tank drives the lifting plate to rise through the first fixed pulley, the second fixed pulley and the suspension rope, and further enables the brush to clean the filter plate again. The sediment adhering to the filter plate is scraped off by the brush, thereby reducing the occurrence of sediment blocking the filter plate.

[0012] Optionally, a first heightening rod is fixedly installed on the bottom surface of the lifting plate. The other end of the first heightening rod is fixedly installed with a first magnet. A second heightening rod is fixedly installed on the inner bottom wall of the filter tank. The other end of the second heightening rod is fixedly installed with a second magnet. The first magnet and the second magnet attract each other.

[0013] By adopting the above technical solution, when the lifting plate descends, the first magnet and the second magnet approach each other, so that the gravitational force between the first magnet and the second magnet gradually increases. After the lifting plate descends to a certain extent, the first magnet and the second magnet attract each other, thereby driving the lifting plate to move downward, and then making the first magnet and the second magnet abut against each other. When the first magnet and the second magnet abut against each other, the blocking plate blocks the drain opening. By the mutual attraction of the first magnet and the second magnet, the amount of water that the water storage tank needs to accumulate to drive the lifting plate to rise is increased, and then when the water storage tank accumulates a certain amount of water to drive the lifting plate to rise, the water inside the water storage tank is discharged from the drain opening and the lifting plate descends again is compensated.

[0014] Optionally, a guide cylinder is fixedly installed on the bottom side of the filter tank. One end of the guide cylinder away from the filter tank is sealed, and the end of the guide cylinder close to the filter tank is communicated with the inside of the filter tank. A guide rod passes through the guide cylinder. One end of the guide rod is fixedly connected to the bottom surface of the lifting plate. A spring is sleeved on the guide rod, and the spring is fixedly installed between the top end of the sleeve and the bottom surface of the lifting plate.

[0015] By adopting the above technical solution, the guide rod cooperates with the guide cylinder, so as to facilitate the lifting of the lifting plate inside the filter tank. When the water storage tank drives the lifting plate to rise to a certain height, the spring is stretched, and the situation that the water storage tank drives the lifting plate to abut against the inner top wall of the filter tank is restricted by elasticity. When the filter plate is blocked and rainwater accumulates on the lifting plate, the lifting plate moves downward, and the speed of the lifting plate descending is delayed by the spring, so as to reduce the situation that the first magnet and the second magnet collide with each other.

[0016] Optionally, the lifting plate is inclined to gradually decrease from the side close to the water collection tank to the other side. A scraping strip abuts against the top surface of the lifting plate. First sliders and second sliders are fixedly installed at both ends of the scraping strip. First sliding grooves are formed on the top surface of the lifting plate for the first sliders to slide between the side of the lifting plate close to the water collection tank and the other side. Second sliding grooves are formed on the inner side wall of the filter tank. The top end of the second sliding groove is close to the water collection tank, and the bottom end of the second sliding groove is inclined away from the water collection tank. The second sliding grooves are used for the second sliders to slide up and down obliquely.

[0017] By adopting the above technical solution, when the lifting plate rises and falls, the first sliders move inside the first sliding grooves, and the second sliders move inside the second sliding grooves, so that the scraping strip moves back and forth on the top surface of the lifting plate, and then the sediment adhered to the top surface of the lifting plate is scraped off. Then the sediment accumulates under the influence of the inclined direction of the lifting plate, which is convenient for cleaning the sediment on the lifting plate.

[0018] Optionally, a recycling box is fixedly installed on the side of the filtering box away from the water collecting box. A recycling port is opened on the side of the filtering box close to the recycling box, and the recycling port penetrates through the side of the recycling box close to the filtering box. When the lifting plate descends to the lowest position, the height of the side of the lifting plate away from the water collecting box is higher than the height of the inner bottom wall of the recycling port. A baffle is arranged on the inner side wall of the recycling box close to the filtering box. A first guiding block and a clamping block are fixedly installed on the surface of the baffle close to the filtering box. A first guiding groove for the first guiding block to slide is opened on the inner side wall of the recycling box close to the filtering box. The first guiding groove is used for the first guiding block to slide along the height direction. The clamping block is located inside the recycling port. A third magnet is fixedly installed on the side of the clamping block away from the baffle, and the third magnet is used to attract the bottom surface of the lifting plate. A floating block is fixedly installed on the bottom side of the baffle.

[0019] By adopting the above technical solution, after the lifting plate descends, the scraping strip scrapes the sediment on the lifting plate towards the recycling port, and the sediment enters the interior of the recycling box from the recycling port, thus facilitating the cleaning of the sediment on the lifting plate. Then part of the rainwater will also enter the interior of the recycling box from the recycling port. When the lifting plate ascends, the lifting plate drives the baffle to move upward through the third magnet. When the lifting plate is higher than the recycling port, the clamping block is clamped with the recycling port, so that the third magnet is separated from the lifting plate. Then the baffle floats inside the recycling box through the floating block, thus blocking the recycling port, and further reducing the situation that the rainwater inside the recycling port flows into the filtering box from the recycling port.

[0020] Optionally, a bottom frame is fixedly installed along the circumferential direction of the inner side wall of the filtering box. A side frame is fixedly installed on the inner wall of the bottom frame. The bottom frame, the side frame and the inner side wall of the filtering box enclose a water guiding groove. The bottom frame is inclined to gradually rise from the side close to the recycling box to the other side. The top surface of the bottom frame close to the recycling box is flush with the inner bottom wall of the recycling port.

[0021] By adopting the above technical solution, part of the rainwater may seep downward through the gap between the circumferential side wall of the lifting plate and the inner side wall of the filtering box. The rainwater is recycled through the water guiding groove, and then the rainwater flows towards the recycling port along the inclined direction of the water guiding groove, and then enters the interior of the recycling box from the recycling port, thus reducing the situation that the rainwater accumulates below the lifting plate.

[0022] Optionally, a plurality of water guiding plates are fixedly installed on the side of the filter plate close to the water collecting box. The water guiding plates are arranged at intervals along the height direction. The distance between two adjacent water guiding plates is less than the thickness of the lifting plate. The water guiding plates are inclined to gradually decrease from the side close to the filter plate to the other side.

[0023] By adopting the above technical solution, the water guide plate guides the rainwater passing through the filter plate into the inside of the water collection tank, thereby reducing the situation where rainwater flows downward along the filter plate, and further reducing the situation where rainwater seeps back into the space below the lifting plate inside the filter tank from the filter plate.

[0024] Optionally, a plurality of water drainage holes are formed on one side of the recovery tank away from the filter tank and on the bottom side of the recovery tank.

[0025] By adopting the above technical solution, the rainwater entering the inside of the recovery tank is discharged from the water drainage holes. As the rainwater inside the recovery tank is drained out, the water level inside the recovery tank gradually drops, and then the baffle also gradually moves downward to open the recovery port, thereby facilitating the water guide groove to collect the rainwater inside the recovery tank.

[0026] Optionally, a geotextile is fixedly installed on the inner wall of the recovery tank, and the geotextile covers each of the water drainage holes.

[0027] By adopting the above technical solution, the geotextile is used to block sediment, thereby reducing the situation where sediment is discharged from the water drainage holes.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When it rains, rainwater enters the inside of the filter tank. After being filtered by the filter plate, the rainwater flows into the inside of the water collection tank. Then, the rainwater inside the water collection tank flows into the inside of the storage tank through the drain pipe. After the rainwater passes through the filter plate, sediment adheres to the filter plate, thereby reducing the amount of rainwater passing through the filter plate. Then, the rainwater accumulates inside the filter tank, thereby increasing the weight of the lifting plate. The lifting plate descends, and at the same time, the lifting plate drives the water storage tank to rise through the first fixed pulley, the second fixed pulley and the suspension rope. When the lifting plate descends, the brush cleans the filter plate. After the first magnet and the second magnet are in mutual contact, the blocking plate blocks the drain port, so that the rainwater accumulates in the water storage tank, and then the weight of the water storage tank increases. Then, the water storage tank moves downward, thereby driving the lifting plate to rise. When the lifting plate rises, the brush cleans the filter plate again, thereby reducing the situation where the filter plate is blocked by sediment;

[0030] 2. When the lifting plate rises and falls, the scraping strip scrapes off the sediment on the lifting plate. When the lifting plate descends to the point where the first magnet and the second magnet attract each other, the sediment on the lifting plate enters the inside of the recovery tank through the recovery port, thereby facilitating the cleaning of the sediment on the lifting plate;

[0031] 3. Sediment and part of the rainwater enter the inside of the recovery tank from the recovery port. The rainwater inside the recovery tank is discharged from the water drainage port, and at the same time, the geotextile blocks the sediment from passing through the water drainage holes, thereby facilitating the discharge of the rainwater inside the recovery tank.

Detailed implementation manners

[0041] The following further describes the present application in detail Figure 1-8 in conjunction with the accompanying drawings.

[0042] An embodiment of the present application discloses a sponge city rainwater drainage regulation system.

[0043] Referring to Figure 1 , a sponge city rainwater drainage regulation system includes a filter box 1, and a water inlet pipe 2 is fixedly installed on the top side of the filter box 1. Drainage facilities discharge rainwater from the water inlet pipe 2 into the interior of the filter box 1.

[0044] Referring to Figure 2 and Figure 3 , a water collecting tank 3 is fixedly installed on one side of the filtering tank 1. An installation opening is formed on the side of the filtering tank 1 close to the water collecting tank 3, and a filter plate 4 is fixedly installed inside the installation opening. After the rainwater inside the filtering tank 1 is filtered by the filter plate 4, the sediment adheres to the filter plate 4, and the rainwater flows into the inside of the water collecting tank 3.

[0045] Referring to Figure 1 , the water collecting tank 3 is provided with a water storage tank 5, and a drain pipe 6 is fixedly installed between the bottom side of the water collecting tank 3 and the top side of the water storage tank 5. A water outlet pipe 7 is fixedly installed on one side wall of the water storage tank 5, and a valve 8 is fitted to the water outlet pipe 7. The rainwater inside the water collecting tank 3 flows into the water storage tank 5 from the drain pipe 6. When the rainwater is needed, the valve 8 is opened, and the rainwater is discharged from the water outlet pipe 7.

[0046] Referring to Figure 3 , a lifting plate 9 is arranged inside the filtering tank 1, and the periphery of the lifting plate 9 abuts against the inner side wall of the filtering tank 1. A brush 10 is fixedly installed on the top surface of the lifting plate 9, and the brush 10 abuts against the filter plate 4. The lifting plate 9 is provided with a lifting mechanism 11, and the lifting mechanism 11 includes a water storage tank 111, a suspension rope 112, a first fixed pulley 113, a second fixed pulley 114, a support rod 115 and a blocking plate 116.

[0047] The water storage tank 111 is located inside the water collecting tank 3, and the top side of the water storage tank 111 has an opening. The peripheral side wall of the water storage tank 111 abuts against the inner side wall of the water collecting tank 3, and a gap is left between the bottom side of the water storage tank 111 and the inner bottom wall of the water collecting tank 3. The first fixed pulley 113 is fixedly installed on the top side of the water collecting tank 3, and the second fixed pulley 114 is fixedly installed on the top side of the filtering tank 1. One end of the suspension rope 112 is fixedly connected to the top side of the water storage tank 111, and the other end of the suspension rope 112 is fixedly connected to the lifting plate 9. The suspension rope 112 is wound around the first fixed pulley 113 and the second fixed pulley 114. The suspension rope 112, the first fixed pulley 113 and the second fixed pulley 114 are a set, and there are two sets in this application.

[0048] Referring to Figure 3 and Figure 4 , a second guiding block 13 is fixedly installed on the peripheral side wall of the water storage tank 111, and a second guiding groove 15 for the second guiding block 13 to slide is formed on the inner side wall of the water collecting tank 3. Through the cooperation of the second guiding block 13 and the second guiding groove 15, the water storage tank 111 is facilitated to lift.

[0049] The support rod 115 is fixedly installed on the inner bottom wall of the water collecting tank 3, and the blocking plate 116 is fixedly installed at the top end of the support rod 115. A drain opening 16 is formed on the bottom side of the water storage tank 111, and the support rod 115 passes through the drain opening 16. The blocking plate 116 is used to block the drain opening 16.

[0050] After the filter plate 4 filters rainwater, sediment is blocked on the filter plate 4, thereby reducing the amount of rainwater passing through the filter plate 4. Then, rainwater accumulates inside the filter box 1, and the weight of the rainwater drives the lifting plate 9 to descend. The lifting plate 9 drives the water storage tank 111 to move upward through the suspension rope 112, the first fixed pulley 113, and the second fixed pulley 114. When the lifting plate 9 descends, the brush 10 clears the sediment on the filter plate 4, and at the same time, the part of the filter plate 4 for filtering rainwater increases. After the lifting plate 9 descends to a certain extent, the inner bottom wall of the water storage tank 111 abuts against the blocking plate 116, and the drain port 16 is blocked by the blocking plate 116, so that rainwater accumulates inside the water storage tank 111, and the weight of the water storage tank 111 increases. When the rainwater accumulated inside the water storage tank 111 is greater than the weight of the lifting plate 9 and the rainwater on the lifting plate 9, the water storage tank 111 drives the lifting plate 9 to rise, so that the brush 10 clears the filter plate 4 again, thereby reducing the situation of sediment blocking the filter plate 4.

[0051] Refer to Figure 3 As shown in the figure, a first heightening rod 17 is fixedly installed on the bottom surface of the lifting plate 9, and a first magnet 19 is fixedly installed at the other end of the first heightening rod 17. A second heightening rod 18 is fixedly installed on the inner bottom wall of the filter box 1, and a second magnet 20 is fixedly installed at the other end of the second heightening rod 18.

[0052] The first magnet 19 and the second magnet 20 attract each other. When the lifting plate 9 descends, the magnetic force between the first magnet 19 and the second magnet 20 gradually increases. After the lifting plate 9 descends a certain height, the first magnet 19 and the second magnet 20 attract and abut against each other, thereby increasing the amount of water that needs to be accumulated for the water storage tank 111 to drive the lifting plate 9 to rise. When the weight of the water storage tank 111 is sufficient to drive the lifting plate 9 to rise, the first magnet 19 and the second magnet 20 move away from each other, and the attractive force between the first magnet 19 and the second magnet 20 gradually weakens, so as to facilitate the rise of the lifting plate 9. At the same time, when the water storage tank 111 moves upward, the blocking plate 116 leaves the drain port 16, and the water inside the water storage tank 111 is discharged from the drain port 16. By increasing the amount of water accumulated in the water storage tank 111 through the mutual attraction of the first magnet 19 and the second magnet 20, the amount discharged from the drain port 16 of the water storage tank 111 is compensated, thereby facilitating the water storage tank 111 to drive the lifting plate 9 to rise.

[0053] Refer to Figure 3 As shown in the figure, a plurality of guide cylinders 22 are fixedly installed on the bottom side of the filter box 1. One end of the guide cylinder 22 away from the filter box 1 is sealed, and one end of the guide cylinder 22 close to the filter box 1 is communicated with the inside of the filter box 1. Each guide cylinder 22 is provided with a guide rod 23, and one end of the guide rod 23 is fixedly connected to the bottom surface of the lifting plate 9. A spring 24 is sleeved on the guide rod 23, and the spring 24 is fixedly installed between the top end of the sleeve and the bottom surface of the lifting plate 9.

[0054] Guided by the guide cylinder 22 and the guide rod 23, it is convenient for the lifting rod to move up and down. When the water storage tank 111 drives the lifting plate 9 to rise, the spring 24 is stretched. When the lifting plate 9 rises to a certain height, it is lifted by the tension of the spring 24, so as to reduce the situation that after the water storage tank 111 drives the lifting plate 9 to rise, the lifting plate 9 abuts against the inner top wall of the filter tank 1. At the same time, when the first magnet 19 and the second magnet 20 abut against each other, and the rainwater accumulated in the water storage tank 111 is sufficient to drive the lifting plate 9 to rise, the spring 24 is beneficial to accelerating the rise of the lifting plate 9, so as to reduce the situation that after the rainwater inside the water storage tank 111 is discharged from the drain port 16, the lifting plate 9 continues to descend. When the lifting plate 9 descends, the spring 24 is compressed and shortened by the extrusion of the lifting plate 9, so as to delay the descending speed of the lifting plate 9, and further reduce the situation that the first magnet 19 and the second magnet 20 collide and damage each other.

[0055] Refer to Figure 3 , Figure 5 , a scraping strip 25 is abutted against the top surface of the lifting plate 9, and the first slider 26 and the second slider 27 are fixedly installed at both ends of the scraping strip 25. A first sliding groove 28 for the first slider 26 to slide is opened on the top surface of the lifting plate 9. When the first slider 26 slides in the first sliding groove 28, the scraping strip 25 moves back and forth on the top surface of the lifting plate 9, so as to scrape off the sediment on the top surface of the lifting plate 9.

[0056] A second sliding groove 29 for the second slider 27 to slide is opened on the inner side wall of the filter tank 1. The top end of the second sliding groove 29 is close to the water collection tank 3, and the bottom end of the second sliding groove 29 is far away from the water collection tank 3 and is inclined. When the lifting plate 9 moves up and down, the lifting plate 9 is clamped with the first slider 26 through the first sliding groove 28, so as to drive the scraping strip 25 to move up and down. When the scraping strip 25 moves up and down, the second slider 27 is guided by the second sliding groove 29 to move up and down obliquely, so as to push the scraping strip 25 to move back and forth on the top surface of the lifting plate 9.

[0057] The lifting plate 9 is inclined gradually from the side close to the water collection tank 3 to the other side. After the scraping strip 25 scrapes off the sediment on the lifting plate 9, the sediment moves under the influence of the inclined direction of the lifting plate 9, so as to facilitate the collection of the sediment on the lifting plate 9.

[0058] A recycling box 30 is fixedly installed on the side of the filter tank 1 far away from the water collection tank 3. A recycling port 31 is opened on the side of the filter tank 1 close to the recycling box 30, and the recycling port 31 penetrates through the side of the recycling box 30 close to the filter tank 1. When the inner top wall of the recycling port 31 is higher than the side of the lifting plate 9 far away from the water collection tank 3 when the lifting plate 9 descends, the first magnet 19 and the second magnet 20 attract each other and abut, so that the lifting plate 9 continues to descend until the side of the lifting plate 9 far away from the water collection tank 3 is slightly higher than the inner bottom wall of the recycling port 31. Thus, the sediment on the lifting plate 9 enters the inside of the recycling box 30 through the recycling port 31. The sediment is recycled through the recycling box 30, so as to facilitate the cleaning of the sediment on the lifting plate 9.

[0059] Both sides of the first slider 26 facing the ends of the first chute 28 are tips that facilitate the pushing of sediment, and both sides of the second slider 27 facing the ends of the second chute 29 are tips that facilitate the pushing of sediment.

[0060] Refer to Figure 6 、 Figure 7 On the inner side wall of the recycling box 30 close to the filtration box 1, a baffle 32 is provided. On the side of the baffle 32 close to the filtration box 1, a first guiding block 12 and a clamping block 33 are fixedly installed. On the inner side wall of the recycling box 30 close to the filtration box 1, a first guiding groove 14 for the first guiding block 12 to slide is provided. The first guiding groove 14 is arranged in the height direction, so as to facilitate the lifting and sliding of the first guiding block 12 inside the first guiding groove 14.

[0061] Refer to Figure 3 、 Figure 6 The clamping block 33 is located inside the recycling opening 31. On the side of the clamping block 33 away from the baffle 32, a third magnet 21 is fixedly installed. The third magnet 21 is used to attract the bottom surface of the lifting plate 9. A floating block 34 is fixedly installed on the bottom side of the baffle 32. After the lifting plate 9 descends until the first magnet 19 and the second magnet 20 are in mutual contact, sediment and rainwater will enter the interior of the recycling box 30 from the recycling opening 31. After the lifting plate 9 rises, the third magnet 21 is adsorbed on the lifting plate 9, so that the baffle 32 moves upward. After the lifting plate 9 is higher than the recycling opening 31, the clamping block 33 is clamped with the inner top wall of the recycling opening 31, so that the third magnet 21 is separated from the lifting plate 9. Then the baffle 32 blocks the recycling opening 31, and at the same time the floating block 34 drives the baffle 32 to float, so as to reduce the situation that the rainwater and sediment inside the recycling box 30 flow into the filtration box 1 from the recycling opening 31.

[0062] Refer to Figure 7 On the side of the recycling box 30 away from the filtration box 1 and on the bottom side of the recycling box 30, a plurality of water drainage holes 35 are provided. A geotextile 36 is fixedly installed on the inner wall of the recycling box 30, and the geotextile 36 covers each water drainage hole 35. The rainwater inside the recycling box 30 is discharged through the water drainage holes 35, and the geotextile 36 is used to block sediment, so as to reduce the situation that sediment is discharged through the water drainage holes 35. After the rainwater inside the recycling box 30 is discharged through the water drainage holes 35, the water level inside the recycling box 30 gradually decreases, so that the floating block 34 drives the baffle 32 to move downward, and then the recycling opening 31 is reopened.

[0063] Refer to Figure 3 、 Figure 8, a bottom frame 37 is fixedly installed along the circumferential direction of the inner side wall of the filtering box 1, and a side frame 38 is fixedly installed on the inner wall of the bottom frame 37. The inner side walls of the bottom frame 37, the side frame 38 and the filtering box 1 enclose a water guide groove 39. The bottom frame 37 is inclined and gradually rises from one side close to the recycling box 30 to the other side. The top surface of the bottom frame 37 on the side close to the recycling box 30 is flush with the inner bottom wall of the recycling port 31.

[0064] Some rainwater may flow downward into the interior of the water guide groove 39 through the gap between the lifting plate 9 and the circumferential side wall of the filtering box 1, and then flow into the interior of the recycling box 30 under the guidance of the water guide groove 39, thereby reducing the accumulation of rainwater in the space below the lifting plate 9 in the filtering box 1.

[0065] Refer to Figure 3 , a plurality of water guide plates 40 are fixedly installed on the side of the filter plate 4 close to the water collecting box 3. The water guide plates 40 are arranged at intervals in the height direction, and the distance between two adjacent water guide plates 40 is less than the thickness of the lifting plate 9. The guide plate is inclined and gradually decreases from the side close to the filter plate 4 to the other side. After the rainwater passes through the filter plate 4, it flows into the interior of the water storage box 111 under the guidance of the water guide plates 40, thereby reducing the situation where the rainwater flows downward along the filtering box 1.

[0066] The implementation principle of the sponge city rainwater drainage regulation system in the embodiment of the present application is as follows: during rain, rainwater flows into the interior of the filtering box 1 from the water inlet pipe 2. After the rainwater passes through the filter plate 4, sediment will clog the filter plate 4. When the amount of rainwater entering the interior of the filtering box 1 is greater than the amount of rainwater passing through the filter plate 4, rainwater accumulates in the filtering box 1. After the rainwater accumulates in the filtering box 1, the weight of the rainwater is applied to the lifting plate 9, and the lifting plate 9 moves downward, and the water storage box 111 moves upward, so that the brush 10 cleans the sediment on the filter plate 4. At the same time, the area of the filter plate 4 for passing rainwater increases, thereby reducing the situation where rainwater overflows from the filtering box 1 after the filter plate 4 is clogged.

[0067] After the filter plate 4 is gradually clogged with sediment, the lifting plate 9 continuously descends. After the bottom surface of the lifting plate 9 far from the water collecting box 3 is flush with the inner top wall of the recycling port 31, the first magnet 19 and the second magnet 20 attract each other and abut, thereby driving the lifting plate 9 to descend to the lowest position, and at the same time the water storage box 111 rises to the highest position, and the blocking plate 116 will block the drain port 16.

[0068] Afterwards, the sediment on the lifting plate 9 enters the interior of the recycling box 30 from the recycling port 31. The rainwater inside the filtering box 1 enters the interior of the recycling box 30 from the recycling port 31 and also flows into the water storage tank 111 after being filtered by the filter plate 4. The rainwater accumulates inside the water storage tank 111, and at the same time, the rainwater on the lifting plate 9 gradually decreases. Afterwards, the water storage tank 111 moves downward and the lifting plate 9 moves upward. The lifting and lowering of the lifting plate 9 drives the brush 10 to clean the sediment on the filter plate 4, thereby reducing the occurrence of sediment clogging the filter plate 4.

[0069] When the lifting plate 9 rises, the baffle 32 is adsorbed on the lifting plate 9 by the third magnet 21, and the baffle 32 seals the recycling port 31 after rising with the lifting plate 9. After the lifting plate 9 is higher than the recycling port 31, the baffle 32 floats and blocks the recycling port 31 through the floating block 34. Afterwards, the rainwater inside the recycling box 30 is discharged from the water draining holes 35, the baffle 32 descends, and the recycling port 31 is reopened, thus facilitating the water guide groove 39 to drain water into the recycling box 30.

[0070] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
