Description

Technical Field

[0001] This invention belongs to the field of rainwater harvesting and utilization technology, specifically relating to a digital sponge city rainwater harvesting and utilization device and its optimization method. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept. It refers to a city that can be like a sponge, with good resilience in adapting to environmental changes and coping with natural disasters caused by rainwater. When it rains, it absorbs, stores, infiltrates, and purifies water, and when needed, it releases and utilizes the stored water, realizing the free migration of rainwater in the city. To align with the concept of sponge cities, rainwater needs to be collected and utilized. Rainwater should be collected during periods of heavy rainfall to prevent adverse effects, such as over-irrigation of farmland. However, since rainfall is uncontrollable, continuous rainwater collection systems consume significant storage space. This wastes space during light rainfall and leaves insufficient storage during heavy rainfall. Furthermore, while collected rainwater requires purification for reuse, continuous collection leads to mixing with previous rainwater, contaminating the purified water. This collection method is inflexible and affects the final cleanliness of the collected rainwater. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a digital sponge city rainwater harvesting and utilization device and its optimization method.

[0004] The technical solution adopted to solve the above technical problems is: a digital sponge city rainwater harvesting and utilization device, including a primary filter component, and a gravity component is provided below the primary filter component, which can slide according to the different weights of the water accumulated in the primary filter component; Below the gravity component is a rotatable flow-stopping component, and below the flow-stopping component is a water storage component; A water intake component is rotatably connected to one side of the water storage component, and the water intake component can slide to open and close. A bottom cleaning component is slidably connected inside the water storage component. A secondary filter assembly is embedded on one side of the primary filter assembly, and the secondary filter assembly is connected to the gravity assembly; An indicator component is embedded on one side of the water storage component.

[0005] Furthermore, the primary filtration assembly includes a funnel with a groove inside, into which a filter screen is inserted. The gravity assembly includes a cylinder with a cover plate at the top and a bottom plate inside. A spring is located inside the bottom plate, and a sleeve is located at the top of the spring. The sleeve is slidably connected to the bottom plate. The flow-stopping assembly includes a flow-stopping plate with a turntable rotatably connected inside. The turntable has multiple through holes, and the flow-stopping plate has multiple drainage holes. A sleeve is located on the outside of the flow-stopping plate. Multiple infusion ports are located in each of the through holes. A slip ring is slidably connected inside each through hole, and a float is installed below the slip ring. Multiple elastic ropes are located at the top of the slip ring. The water storage assembly includes a bottom shell, and the flow-stopping plate is installed between the bottom shell and the cylinder.

[0006] Through the above technical solution, the funnel is installed on top of the cover plate. Rainwater passes through the first layer of the filter screen to remove large impurities before entering the funnel. Only when the funnel reaches a certain weight can the spring contract. The spring contraction causes the sleeve to slide downwards, creating a gap between the sleeve and the cover plate for rainwater to pass through. When rainfall is light, the weight of the water in the funnel is insufficient to allow rainwater to enter the cylinder. The cylinder collects rainwater primarily to reduce the amount of rainwater and prevent adverse effects. During light rainfall, the cylinder is not needed for rainwater collection, reducing the use of the spring and increasing its lifespan. It also prevents unnecessary water collection from occupying the space inside the cylinder. When rainfall is heavy, the weight of the water in the funnel meets the spring's contraction requirement, allowing rainwater to enter the cylinder. A water purification reagent is added to the cylinder for secondary treatment of the rainwater. The purified rainwater then flows into the bottom shell for storage. If the rainfall continues, the cylinder... Rainwater is continuously injected into the tank, and the collected rainwater mixes with the purified rainwater, reducing the water quality inside the bottom shell. The turntable can be rotated after the bottom shell is filled with water, preventing the through-hole from connecting to the leak hole and thus blocking rainwater flow. A sleeve plate is fixedly connected to the top of the bottom shell. The internal structure of the flow-stopping plate is hollow and contains liquid water purifier. The purifier flows out from the inclined inlet. Multiple inlets are located at the same height. When no water is injected, the slip ring blocks multiple inlets. When water passes through the turntable, it impacts the float, causing the float to slide down and open the inlets to release the purifier. The larger the water volume, the greater the impact and the larger the inlet opening. After the water passes, multiple elastic ropes pull the slip ring back to its original position, continuing to block the inlets. When the water causes the float to block the through-hole, the float can prevent water from continuing to enter the bottom shell, automatically isolating the water flow and ensuring the water quality inside the cylinder remains unaffected, facilitating subsequent use.

[0007] Furthermore, the water intake assembly includes a control valve, and a through groove is provided on one side of the bottom shell. The control valve is rotatably connected in the through groove, and sliding plates are provided on both sides of the control valve. Rotating the control valve can turn the water in the cylinder out from the sliding plates.

[0008] The above technical solution facilitates the testing of water quality inside the cylinder. If the water quality does not meet the usage standards, water purification reagents or drugs can be added to the slide plate located outside the bottom shell to adjust the water quality.

[0009] Furthermore, the two slide plates are slidably connected to both sides of the control valve, and a sealing plate is slidably connected to the top of the slide plates. Two water channels are symmetrically opened inside the control valve, and a vertical plate is provided on one side of the bottom shell. A rotating plate is rotatably connected to the vertical plate.

[0010] With the above technical solution, the sealing plate on one side of the slide plate is slid to allow water to enter the slide plate. Rainwater will flow from the water channels on both sides into the interior of the other side of the slide plate. After the other side of the slide plate is slid out from the control valve, the water can be discharged. This structure can drain the water stored in the bottom shell.

[0011] Furthermore, the bottom cleaning assembly includes a collection plate, a scraper is slidably connected inside the collection plate, and the bottom cleaning assembly includes a partition, the collection plate and the partition being slidably connected to the bottom shell respectively.

[0012] Through the above technical solution, long-term water storage will cause dirt to settle and form scale, which will affect water quality. The collection plate can collect the scale and the sliding scraper can clean the scale. When the sliding collection plate is treating the scale, the partition is inserted into the bottom shell to cut off the water flow and prevent the water in the bottom shell from leaking out.

[0013] Furthermore, the partition plate has two insertion holes, and the bottom shell has a slot on one side, in which a card plate is slidably connected, and the card plate is adapted to the insertion holes.

[0014] Through the above technical solution, the sliding plate can block the collecting plate for limiting its position, and the plate can pass through the insertion hole to limit the partition during the sliding process.

[0015] Furthermore, the secondary filter assembly includes a dispensing tank, a connecting rod is slidably connected inside the dispensing tank, a connecting groove is provided on the cover plate, the dispensing tank is embedded in the connecting groove, and the connecting rod is fixedly connected to the sleeve.

[0016] With the above technical solution, when the sleeve slides down to open the water inlet, it will drive the connecting rod to slide. The water purification material is added to the mixing tank in advance. When rainwater begins to enter the cylinder, the water purification material will also enter the cylinder. This makes it convenient to add water purification agent and prevents the effect from weakening and causing waste after adding water purification agent in advance.

[0017] Furthermore, a cavity is provided inside the cylinder, a filter plate is embedded in the cavity, and a surrounding plate is provided on the outside of the cylinder.

[0018] With the above technical solution, if the bottom shell is full of water and the cylinder is about to be full of water, rainwater will continue to affect the water quality inside the cylinder and overflow from the funnel if no outlet is opened inside the cylinder. Therefore, a filter plate is set to allow the excess water to be discharged. In this way, the rainwater discharged from the filter plate is purified, while the rainwater at the funnel can continuously enter the cylinder. This is equivalent to replacing the water that originally overflowed from the funnel with the water flowing out from the filter plate. The water flowing out from the filter plate is cleaner than the water overflowing from the funnel, and the water has a better performance after flowing out.

[0019] Furthermore, the indicating component includes a glass plate, which is embedded in one side of the bottom shell. A bracket is provided on one side of the glass plate, and a sliding rod is slidably connected inside the bracket. A floating plate is provided on both sides of the sliding rod.

[0020] With the above technical solution, since rainwater will continuously flow into the cylinder, if there is no outlet inside the cylinder, the spring will not rebound after the cylinder and bottom shell are full of water. The external rainwater will continuously mix with the internal rainwater and then overflow, which will affect the quality of the previously collected rainwater and greatly weaken the purification effect of the rainwater. When the water level in the bottom shell reaches the required amount of water, the turntable can be rotated to block the water flow in advance. The misalignment of the through holes and the leakage holes can achieve the effect of stopping the flow. By observing the height of the floating plate, it is convenient to observe the water level inside the bottom shell.

[0021] Furthermore, the primary filter component can perform preliminary filtration and purification of water. The gravity component slides according to the amount of water accumulated in the primary filter component. Water can only flow into the gravity component when the amount of water in the primary filter component reaches a certain weight. When the gravity component slides, it drives the secondary filter component to slide to perform secondary purification of the water. The water in the gravity component will flow into the water storage component. The flow-stopping component can control the water flow in the gravity component. When the rainfall is not large enough, the amount of water in the primary filter component is insufficient, and the water will not flow into the gravity component. When the rainfall causes the amount of water in the primary filter component to reach a specified weight, the water will flow into the gravity component for collection and purification. When the gravity component is almost full, it can discharge excess water for self-protection. The flow-stopping component can block the water accumulation in the gravity component when the water storage component is full.

[0022] The beneficial effects of this invention are as follows: (1) This invention makes rainwater cleaner through multiple filtration and purification, making it more convenient to use later. It can also use a control valve to sample the rainwater in the bottom shell to test whether it meets the usage standards. Furthermore, it can use a control valve to add rainwater purification items to adjust the water quality of the rainwater in the bottom shell. (2) The present invention can block the flow of water in the cylinder by controlling the turntable. Since the water inside the bottom shell has been purified, and new rainwater will continuously flow into the cylinder, the turntable can isolate the water on both sides after the bottom shell is filled with water, preventing the purified water from being polluted again. When the water falls and impacts the float, the float opens the inlet by pulling the slip ring, and liquid water purification agent flows out of the inlet to further purify the water. If there is no manual intervention, when the water inside the bottom shell is filled, the float will rise with the water level and eventually block the turntable, automatically isolating the water and ensuring that the water inside the bottom shell will not be affected by subsequent sewage after it is filled. (3) The present invention can automatically discharge excess water through the filter plate. When the water level reaches the height of the filter plate, if there is still rainwater being collected, the rainwater will flow out from the filter plate. The purified water flowing out from the filter plate will replace the sewage overflowing from the funnel. When the rainfall is large, it can replace and purify the rainwater, so that the rainwater that cannot be collected can also be treated. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Rainfall refers to the total amount of precipitation in a specific area over a given period of time, usually measured in millimeters (mm) or inches (in). This indicator is of great importance in fields such as agriculture, water resource management, and meteorology, helping people understand precipitation patterns and their impact on the environment and society. Example 1

[0027] like Figures 1-9 As shown, the digital sponge city rainwater harvesting and utilization device of this embodiment includes a primary filter component 1, and a gravity component 2 is provided below the primary filter component 1. The gravity component 2 can slide according to the different weights of the water accumulated in the primary filter component 1. Below the gravity component 2 is a rotatable flow-stopping component 3, and below the flow-stopping component 3 is a water storage component 4; like Figures 1-5As shown, the primary filter component 1 can perform preliminary filtration and purification of water. The gravity component 2 will slide according to the amount of water in the primary filter component 1. Only when the amount of water in the primary filter component 1 reaches a certain weight can it flow into the gravity component 2. When the gravity component 2 slides, it drives the secondary filter component 7 to slide to perform secondary purification of water. The water in the gravity component 2 will flow into the water storage component 4. The flow-stopping component 3 can control the water flow in the gravity component 2. When the rainfall is not large enough, the amount of water in the primary filter component 1 is not enough, and the water will not flow into the gravity component 2. When the rainfall makes the amount of water in the primary filter component 1 reach a specified weight, the water will flow into the gravity component 2 for collection and purification. When the gravity component 2 is almost full of water, it can discharge the excess water for self-protection. The flow-stopping component 3 can block the water storage in the gravity component 2 when the water storage component 4 is full.

[0028] A water-inlet component 5 is rotatably connected to one side of the water storage component 4. The water-inlet component 5 can slide to open and close. A bottom cleaning component 6 is slidably connected inside the water storage component 4. A secondary filter assembly 7 is embedded on one side of the primary filter assembly 1, and the secondary filter assembly 7 is connected to the gravity assembly 2; An indicator component 8 is embedded on one side of the water storage component 4.

[0029] like Figures 1-5 As shown, the primary filtration assembly 1 includes a funnel 101 with a groove 102 inside, into which a filter screen 103 is inserted. The gravity assembly 2 includes a cylinder 201 with a cover plate 202 at the top and a bottom plate 203 inside. A spring 204 is located inside the bottom plate 203, and a sleeve 205 is located at the top of the spring 204. The sleeve 205 is slidably connected to the bottom plate 203. The flow-stopping assembly 3 includes a flow-stopping plate 301. A turntable 302 is rotatably connected inside the flow stop plate 301. The turntable 302 has multiple through holes 303. The flow stop plate 301 has multiple leakage holes 309. A sleeve plate 304 is provided on the outside of the flow stop plate 301. Multiple infusion ports 305 are provided in each of the through holes 303. A slip ring 306 is slidably connected inside the through holes 303. A float ball 307 is installed below the slip ring 306. Multiple elastic ropes 308 are provided on the top of the slip ring 306. The turntable 302 is hollow and can be filled with liquid water purifier. When the infusion port 305 is open, the water purifier inside the turntable 302 will flow out through the infusion port 305. The opening of the infusion port 305 is tilted downwards to prevent water from rapidly flowing into the turntable 302 as it passes through. The water storage assembly 4 includes a bottom shell 401, a flow stop 301 installed between the bottom shell 401 and the cylinder 201, and a funnel 101 installed on top of the cover plate 202. Rainwater passes through the first layer of the filter screen 103 to remove large impurities and enters the funnel 101. Only when the water in the funnel 101 reaches a certain weight can the spring 204 contract. The contraction of the spring 204 causes the sleeve 205 to slide downwards, creating a gap between the sleeve 205 and the cover plate 202 to allow rainwater to pass through. When the rainfall is light, the weight of the water in the funnel 101 is insufficient to prevent rainwater from flowing through. Rainwater is allowed to enter the cylinder 201. The main purpose of collecting rainwater in the cylinder 201 is to reduce the amount of rainwater and prevent adverse effects. When the rainfall is light, rainwater does not need to be collected through the cylinder 201, which reduces the use of the spring 204 and prevents unnecessary rainwater from occupying the space inside the cylinder 201. When the rainfall is heavy, the weight of the water stored in the funnel 101 meets the contraction requirement of the spring 204, and the rainwater will enter the cylinder 201. A water purification reagent is added to the cylinder 201 to perform secondary treatment on the rainwater. The purified rainwater will then flow into the bottom shell 401. The water is stored inside the cylinder 201. If the rainfall continues, rainwater will be continuously injected into the cylinder 201. The collected rainwater will mix with the purified rainwater, reducing the water quality inside the bottom shell 401. After the bottom shell 401 is full of water, the turntable 302 can be rotated to prevent the through hole 303 from connecting with the leakage hole 301, thereby blocking the flow of rainwater. The sleeve plate 304 is fixedly connected to the top of the bottom shell 401. The internal structure of the flow stop plate 301 is hollow and contains liquid water purifier. The purifier can flow out from the inlet 305 on the inclined surface. Multiple inlets 305 are opened at the same height. Without water injection, the slip ring 306 will block multiple infusion ports 305. When water passes through the turntable 302, the water will impact the float 307. The float 307 will drive the slip ring 306 to slide down, causing the infusion ports 305 to open and release the purifying agent. The larger the water volume, the greater the impact force, and the larger the opening of the infusion port 305. The more liquid water purifying agent flows out per unit time, thus ensuring that the amount of liquid water purifying agent flowing out can mix with the incoming water in a certain proportion, avoiding resource waste while ensuring that the water is fully purified.

[0030] When the water stops flowing through the turntable 302, the impact force on the float 307 gradually decreases, and multiple elastic ropes 308 pull the slip ring 306 to reset. The infusion port 305 is blocked again by the slip ring 306. When the water below the float 307 increases, it will push the float 307 to block the through hole 303. At this time, the float 307 can prevent the water flow from continuing to enter the bottom shell 401, thus automatically isolating the water flow and ensuring that the water quality in the cylinder 201 is not affected, which is convenient for subsequent use.

[0031] like Figure 5 , Figure 6As shown, the water intake assembly 5 includes a control valve 501. A through groove 402 is provided on one side of the bottom shell 401. The control valve 501 is rotatably connected in the through groove 402. Slide plates 502 are provided on both sides of the control valve 501. Rotating the control valve 501 can turn the water in the cylinder 201 out through the slide plates 502, which facilitates the testing of the water quality in the cylinder 201. If the water quality does not meet the usage standards, water purification reagents or drugs can be added to the slide plates 502 located outside the bottom shell 401 to adjust the water quality.

[0032] like Figures 1-3 As shown, two slide plates 502 are slidably connected to both sides of the control valve 501. A sealing plate 503 is slidably connected to the top of the slide plate 502. Two water channels 504 are symmetrically opened inside the control valve 501. A vertical plate 405 is provided on one side of the bottom shell 401. A rotating plate 406 is rotatably connected to the vertical plate 405. By sliding the sealing plate 503 on one side of the slide plate 502, water can enter the slide plate 502. Rainwater will flow from the water channels 504 on both sides into the slide plate 502 on the other side. After sliding the slide plate 502 on the other side out of the control valve 501, the water can be discharged. This structure can discharge the water stored in the bottom shell 401.

[0033] like Figure 7 As shown, the bottom cleaning component 6 includes a collection plate 601, a scraper 602 slidably connected inside the collection plate 601, and a partition 603. The collection plate 601 and the partition 603 are slidably connected to the bottom shell 401. Long-term water storage will cause dirt to settle and form scale, which will affect water quality. The collection plate 601 can collect the scale and the sliding scraper 602 can clean the scale. When the sliding collection plate 601 is processing the scale, the partition 603 is inserted into the bottom shell 401 to cut off the water flow and prevent the water in the bottom shell 401 from leaking out.

[0034] like Figure 5 , Figure 7 As shown, the partition 603 has two insertion holes 604, and the bottom shell 401 has a slot 403 on one side. A card plate 404 is slidably connected in the slot 403. The card plate 404 is adapted to the insertion hole 604. The sliding card plate 404 can block the collecting plate 601 for limiting, and the card plate 404 can pass through the insertion hole 604 to limit the partition 603 during the sliding process.

[0035] like Figure 3 , Figure 8As shown, the secondary filter assembly 7 includes a mixing tank 701, a connecting rod 702 slidably connected inside the mixing tank 701, a connecting groove 206 opened on the cover plate 202, the mixing tank 701 is embedded in the connecting groove 206, the connecting rod 702 is fixedly connected to the sleeve 205, when the sleeve 205 slides down to open the water inlet, it will drive the connecting rod 702 to slide. Water purification materials are added to the mixing tank 701 in advance. When rainwater begins to enter the cylinder 201, the water purification materials will also enter the cylinder 201. This makes it convenient to add water purification agent and prevents the effect from weakening and causing waste after adding water purification agent in advance. Example 2

[0036] like Figures 1-3 As shown, a cavity 207 is provided inside the cylinder 201, and a filter plate 208 is embedded in the cavity 207. A surrounding plate 209 is provided on the outside of the cylinder 201. The indicating component 8 includes a glass plate 801, which is embedded in one side of the bottom shell 401. A bracket 802 is provided on one side of the glass plate 801, and a sliding rod 803 is slidably connected in the bracket 802. Floating plates 804 are provided on both sides of the sliding rod 803. Since rainwater will continuously flow into the cylinder 201, if there is no water outlet inside the cylinder 201, the spring 204 will not rebound after the cylinder 201 and the bottom shell 401 are full of water. External rainwater will continuously mix with internal rainwater and overflow, which will affect the quality of the previously collected rainwater and greatly weaken the rainwater purification effect. When the water level in the bottom shell 401 reaches the required water volume, the turntable 302 can be rotated to lift the water. The water flow is blocked by the misalignment of the through hole 303 and the drain hole 301, which can stop the flow. By observing the height of the floating plate 804, it is convenient to observe the water level inside the bottom shell 401. When the bottom shell 401 is full of water, if the cylinder 201 is also about to be full of water, if no outlet is opened in the cylinder 201, the rainwater will continue to affect the water quality inside the cylinder 201 and overflow from the funnel 101. Therefore, the filter plate 208 is set to allow the excess rainwater to be discharged. In this way, the rainwater discharged from the filter plate 208 is purified, and the rainwater at the funnel 101 can continuously enter the cylinder 201, which is equivalent to replacing the water that originally overflowed from the funnel 101 with the water flowing out from the filter plate 208. The water flowing out from the filter plate 208 is cleaner than the water that overflowed from the funnel 101, and the water has a better effect after flowing out.

[0037] The working principle of this embodiment is as follows: During rainfall, rainwater enters the funnel 101 after being filtered by the filter screen 103. When the rainfall in the funnel 101 reaches a certain weight, the spring 204 contracts, and the rainwater enters the cylinder 201. A water purification substance is added to the mixing tank 701 beforehand. When the rainwater enters, the water purification substance enters along with it. Finally, the water flows into the bottom shell 401. The control valve 501 can rotate the slide plate 502 located inside the bottom shell 401. If the water quality in the slide plate 502 needs to be tested and improvement is required, water-injecting substances can be added to the slide plate 502. The control valve 501 is turned to allow purified water to enter the bottom shell 401. When the water stored in the bottom shell 401 is needed, the slide plate 502 located on the outside is slid outward to drain the water from the bottom shell 401. If the water is not needed to be drained, the slide plate 502 is retracted and the sealing plate 503 is closed. The water level in the bottom shell 401 is observed using the floating plate 804. When the bottom shell 401 is not full of water but the water level reaches the required amount of water, in order to protect this part of purified water from the influence of subsequent water flow, the turntable 302 is rotated to block the water flow, so that the water in the bottom shell 401 will not be contaminated by subsequent rainwater.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
