Description

Technical Field

[0001] The invention belongs to the technical field of sponge city rainwater purification, and specifically relates to a sponge city rainwater purification system. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". The internationally accepted term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates and purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city.

[0003] When a sponge city encounters severe convective weather, the trees, flowers and other plants planned in the sponge city, as well as urban garbage and other debris will gather in the rainwater wells with the rainwater, causing blockage and poor drainage in the rainwater wells, seriously affecting the drainage of the sponge city and causing problems such as waterlogging in the sponge city; simply increasing the number of rainwater wells cannot solve or alleviate the occurrence of the above problems.

[0004] In addition, the rainwater wells in sponge cities also play the role of collecting and purifying rainwater to realize the collection and reuse of rainwater in sponge cities. However, when sponge cities encounter strong convective weather, the collection and purification equipment connected to the rainwater wells will also affect the drainage of sponge cities and affect the rapid discharge of rainwater, leading to problems such as waterlogging in sponge cities.

[0005] The Chinese patent application publication number CN117164060B discloses a sponge city rainwater purification system, including a water collection device, a water purification device and a water storage device. The water purification device includes a filter cartridge. Two groups of water inlet pipes are arranged on the top of the side wall of the filter cartridge. The two groups of water inlet pipes are arranged along the tangent direction of the filter cartridge and are symmetrically arranged about the center of the filter cartridge. The water inlet pipes are connected to the water collection device. A water outlet pipe is arranged at the bottom of the side wall of the filter cartridge. One end of the water outlet pipe is located at the center of the filter cartridge, and the other end is connected to the water storage device. A scum collection net is provided in the center of the filter cartridge. The scum collection net includes a vortex collection part, a guide part and a scum storage part. The vortex collection part is used to collect scum and solid impurities. By setting the filter cartridge and the scum collection net, the water permeability of the scum collection net is prevented from being reduced, which will affect the rotation speed and formation of the system vortex, and ensure that the system can work normally. The sponge city rainwater purification system can only purify the rainwater in the sponge city. It cannot prevent the debris in the sponge city from clogging the rainwater well, affecting the drainage efficiency of the rainwater in the sponge city, and easily causing problems such as waterlogging in the sponge city.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention can effectively prevent the debris generated in the sponge city from clogging the rainwater well by installing a water collection mechanism that automatically adjusts according to the precipitation intensity on the rainwater well, thereby improving the drainage efficiency of the rainwater well for heavy rainfall and reducing the problems of waterlogging in the sponge city. The present invention can install a water purification mechanism in the rainwater well, which can adjust the position of rainwater purification according to the precipitation intensity, thereby preventing rainwater purification from affecting the drainage efficiency of the rainwater well. The reprocessing mechanism temporarily stores the rainwater collected in the rainwater well, and after purification again to meet the standards, it provides water sources for greening irrigation, lakeside water, etc., thereby improving the utilization efficiency of rainwater. The water collection mechanism not only collects rainwater in the sponge city through the rainwater well, but also collects rainwater seeping from the permeable sidewalk, thereby improving the collection efficiency of rainwater in the sponge city and reducing the waste of water resources.

[0020] (2) The water collection mechanism replaces the common flat-type rainwater grate with an inverted "concave"-shaped rainwater grate on the rainwater well. When the sponge city encounters heavy rainfall, a large amount of rainwater quickly flows into the water collection tube. The rainwater cannot flow out along the leaking hole in a short time. Under the action of rainwater, the lifting float rises along the water collection trough through the float wheel, and pushes the grate top plate upward through the grate side plate. The rainwater grate as a whole protrudes from the well mouth of the rainwater well. The debris in the sponge city gathers at the grate side plate. The water level near the rainwater well rises briefly. The debris is pushed away by the rising water level, and the rainwater will flow into the rainwater well again along the rainwater grate. Even if the debris continues to gather near the grate side plate, the rainwater can still flow into the rainwater well along the upper part of the grate side plate, eliminating the possibility of the rainwater grate being blocked by debris and improving the drainage efficiency of the rainwater well.

[0021] (3) The warning rod in the warning groove in the lifting groove rises with the side plate of the grate, and serves as a reminder after the rainwater grate protrudes out of the rainwater well, preventing vehicles or pedestrians from colliding with the rainwater grate and avoiding accidents. A warning light and a warning horn can be set in the warning rod, and the battery can be used for long-term power supply to enhance the warning effect of the warning rod; the lifting spring in the protective groove can shrink when the warning rod is under pressure, thereby preventing the warning rod from accidentally injuring pedestrians or vehicles.

[0022] (4) The water purification mechanism filters rainwater by installing a water purification cylinder in the rainwater well. The conical leaking plate on the top of the water purification cylinder can perform preliminary filtering of debris, preventing debris from falling directly into the water purification cylinder and damaging the filter net bag; the rainwater treatment structure in the water purification cylinder re-processes the rainwater after preliminary filtration; the guide magnetic strip increases the friction between the annular debris cylinder and the water purification cylinder and the guide groove on the rainwater well by magnetic adsorption, preventing the annular debris cylinder from floating up or down quickly when affected by buoyancy, affecting the rainwater filtration effect of the water purification mechanism in the rainwater well.

[0023] (5) The annular debris cylinder collects debris flowing into the rainwater well through at least two debris net bags, initially reducing the debris content in the rainwater and performing preliminary purification on the debris in the rainwater. When in use, the debris net bag is stuck in the annular debris cylinder and replaced or cleaned after a period of use; the dirt-blocking spurs on the debris retaining teeth can prevent debris from escaping from the debris net bag when the water level in the rainwater well is too high, thereby preventing the debris from being re-mixed with the rainwater and ensuring the purification effect of the rainwater.

[0024] (6) A hollow annular auxiliary cylinder is arranged at the bottom of the annular debris cylinder. When hit by heavy rainfall, the water level in the rainwater well rises rapidly. Under the action of the annular auxiliary cylinder, the annular debris cylinder floats up in the rainwater well and drives the auxiliary cross bar to move upward through the auxiliary connecting rod. At this time, if the rainwater grate has not moved up, the auxiliary cross bar is at the top of the strip-shaped auxiliary groove. The auxiliary cross bar will push the lifting column up, thereby assisting in pushing the side plate of the grate up, thereby assisting in opening the rainwater grate and preventing the rainwater grate from being unable to move upward due to insufficient buoyancy. The drainage hole facilitates the rainwater in the annular debris cylinder to flow into the water purification sleeve in the water purification cylinder, so as to further filter the rainwater.

[0025] (7) The rainwater treatment structure adjusts the height of the hollow sleeve in the water purification regulating cylinder through the buoyancy generated by the rainwater in the rainwater well, thereby adjusting the drainage efficiency according to the amount of water in the rainwater well, preventing the rainwater treatment structure from affecting the drainage effect of the rainwater well and reducing the probability of waterlogging in the sponge city; the hollow sleeve pushes the water purification sleeve up and down along the water purification cylinder by adjusting the vertical rod to achieve the purpose of adjusting the height of the water purification sleeve.

[0026] (8) The water purification adjusting parts symmetrically arranged on the hollow sleeve push the hollow sleeve up along the vertical adjustment hole under the action of the buoyancy of the rainwater that quickly gathers in the rainwater well. The height of the water purification sleeve can be adjusted by adjusting the vertical rod, so that the position of the water purification sleeve is moved up, and the water purification port is moved up to the drain hole, which is convenient for quickly discharging the rainwater to be purified through the drain hole, and preventing the excessive amount of rainwater in the rainwater well from causing problems such as poor drainage; the adjustment pulley cooperates with the adjustment slide groove, which not only improves the adjustment efficiency of the hollow sleeve, but also prevents the hollow sleeve from rotating when the buoyancy of each water purification adjusting part is uneven, thereby affecting the adjustment effect of the hollow sleeve.

[0027] (9) The water purification outlet inclined on the side of the water purification sleeve is discharged into the water filter bag in the water filter hole, so that the impurities in the rainwater are further filtered and processed, and the content of impurities in the rainwater is further reduced; when hit by heavy rainfall, the water purification sleeve floats up, and the water purification outlet moves up to the drain hole, and the rainwater is quickly discharged along the drain hole, preventing the rainwater purification mechanism from affecting the drainage efficiency of heavy rainfall, and reducing the occurrence of problems such as waterlogging in sponge cities.

[0028] (10) The reprocessing agency collects and stores the rainwater that has been initially purified and filtered by the water purification agency in the rainwater well through a water storage tank connected to the drainage pipe, and then further processes the initially purified rainwater through the rainwater reprocessing equipment connected to the treatment pipe. After the treated rainwater meets the reuse standards, it provides water for greening irrigation, lakeside water, etc., thereby improving the utilization efficiency of rainwater and reducing the waste of rainwater resources.

[0029] In summary, the water collection mechanism of the present invention replaces the common flat rainwater grate by arranging an inverted "concave"-shaped rainwater grate on the rainwater well. When the sponge city encounters heavy rainfall, a large amount of rainwater quickly flows into the water collection tube, and the rainwater cannot flow out along the leakage hole in a short time. Under the action of rainwater, the lifting float rises along the water collection trough through the float wheel, and the grate top plate is pushed up by the grate side plate. The rainwater grate as a whole protrudes out of the wellhead of the rainwater well, which effectively prevents the rainwater well from being blocked by debris generated in the sponge city, eliminates the possibility of the rainwater grate being blocked by debris, and improves the drainage efficiency of the rainwater well; the water purification mechanism of the present invention filters the debris contained in the rainwater through multiple filtration and purification methods, which can effectively reduce the content of debris in the rainwater, improve the water quality of the purified rainwater, and facilitate the water source for greening irrigation water, lakeside water, etc. after purification by the re-processing mechanism to improve the utilization efficiency of rainwater and prevent the waste of water resources.

[0053] A method for a sponge city rainwater purification system, the steps comprising:

[0054] S1. Planning of rainwater purification system in sponge cities;

[0055] This system is planned in the rainwater gathering points, green plants and tree concentration areas of sponge cities. It is especially suitable for planning in green spaces, gardens and permeable pavements in sponge cities. It can effectively enhance the sponge city's ability to resist heavy rainfall, reduce the impact of heavy rainfall on sponge cities, prevent the occurrence of waterlogging in sponge cities, and improve the utilization efficiency of rainwater in sponge cities.

[0056] S2, regulation of water collection mechanism 2 during heavy rainfall;

[0057] When the sponge city encounters heavy rainfall, rainwater flows quickly into the rainwater well 1, and the gathered rainwater flows into the water collecting barrel 207 along the water collecting funnel 209. The rainwater in the water collecting barrel 207 cannot flow out along the leaking hole 208 in a short time, and the water level in the water collecting barrel 207 rises. Under the action of rainwater, the lifting float 211 rises along the water collecting trough through the floating wheel 212, and the lifting column 206 drives the grate side plate 210 to push the grate top plate 202 to rise. The lifting wheel 204 moves along the lifting groove, and the rainwater grate 201 protrudes from the wellhead of the rainwater well 1 as a whole. As the rainwater gathers towards the rainwater well 1, the debris in the sponge city gathers at the grate side plate 210, and the rainwater flows into the rainwater well 1 along the upper part of the grate side plate 210, which can not only prevent the rainwater grate 201 from being blocked, but also prevent the debris from blocking the inside of the rainwater well 1, causing the rainwater well 1 to fail and lose its drainage capacity.

[0058] The warning rod 203 connected to the lifting connecting rod 205 in the warning groove in the lifting groove rises with the grate side plate 210, and serves as a reminder after the rainwater grate 201 protrudes from the rainwater well 1, preventing vehicles or pedestrians from colliding with the rainwater grate 201 and avoiding accidents. The warning rod 203 is a bendable and flexible warning rod 203. When the warning rod 203 is hit or squeezed, the warning rod 203 bends, and the lifting connecting rod 205 squeezes the lifting spring 214 in the protective groove 213, so that the warning rod 203 retracts, thereby ensuring the safety of the warning rod 203 and the impact object.

[0059] S3, water purification mechanism 4 filters and purifies rainwater;

[0060] After being adjusted by the water collecting mechanism 2, the rainwater grate 201 can block a part of the debris, and the relatively short debris will flow into the rainwater well 1 along the rainwater grate 201, and the rainwater in the permeable pipe 3 will directly flow into the rainwater well. Under the action of the conical water leakage plate 406, the rainwater flows to the rainwater treatment structure in the water purification cylinder 401 for further treatment, and the conical water leakage plate 406 filters the debris in the rainwater again, and the debris slides along the conical water leakage plate 406 into the debris net bag 405 in the annular debris cylinder 404. After the debris is filtered by the debris net bag 405, the rainwater flows into the water purification cylinder 401 along the drainage hole 414; the dirt blocking oblique spikes 415 on the debris blocking teeth 412 can prevent the debris from overflowing the debris net bag 405 with the rainwater, thereby restraining the debris.

[0061] The rainwater filtered for the second time is further processed by the rainwater processing structure in the water purification cartridge 401. Specifically, the rainwater flows through the water purification port 417 on the water purification sleeve 416 in the water purification cartridge 401 along the water filter hole 410 to the water filter net bag, and the sundries and impurities in the rainwater are further filtered and purified, thereby further reducing the impurity content in the rainwater.

[0062] As the amount of rainwater flowing into the rainwater well 1 increases due to heavy rainfall, a large amount of rainwater gathers in the rainwater well 1, and the rainwater begins to gather at the bottom of the rainwater well 1. The rainwater enters the clean water regulating cylinder 420 along the vertical regulating hole on the side of the clean water regulating cylinder 420, and the hollow sleeve 422 generates buoyancy. At the same time, the lightweight regulating ball 418 on the regulating connecting rod 419 generates buoyancy under the action of rainwater at the bottom of the rainwater well 1. Under the buoyancy of the hollow sleeve 422 and the lightweight regulating ball 418, the adjusting pulley 421 of the hollow sleeve 422 rises along the adjusting chute, and the clean water sleeve 416 is pushed up by the adjusting vertical rod 411, and the clean water outlet 417 moves to the drain hole 409. The rainwater that has not been purified by the water filter bag begins to flow out quickly along the drain hole 409 to improve the water inlet efficiency of the rainwater well 1 and prevent natural disasters such as waterlogging in the sponge city.

[0063] As the rainwater in the rainwater well 1 continues to increase, the annular auxiliary cylinder 402 generates buoyancy under the action of the rainwater. Under the action of the buoyancy of the annular auxiliary cylinder 402, the annular auxiliary cylinder 402 pushes the annular debris cylinder 404 to move along the guide grooves on the clean water cylinder 401 and the rainwater well 1 through the guide magnetic strip 403. The guide magnetic strip 403 increases the friction with the guide groove by magnetic attraction to prevent the annular auxiliary cylinder 402 from rising or falling at will. As the annular auxiliary cylinder 402 rises, the annular debris cylinder 404 and There is a gap between the water purification cylinders 401, so rainwater can flow directly into the drainage pipe 5 without passing through the conical leaky plate 406, further improving the water inlet efficiency of the rainwater well 1 and reducing the amount of rainwater in the sponge city; in addition, the buoyancy generated by the annular auxiliary cylinder 402 drives the auxiliary cross bar 407 along the auxiliary adjustment hole 413 through the auxiliary connecting rod 408 to push the lifting column 206 to rise, thereby generating an auxiliary force on the rainwater grate 201, pushing the rainwater grate 201 to rise, and improving the entry efficiency of the rainwater grate 201.

[0064] S4. Reprocessing of rainwater;

[0065] The rainwater at the bottom of the rainwater well 1 is merged with the treated rainwater in the adjacent rainwater well 1 through the drainage pipe 5, and finally flows into the water storage tank 6. The city's distant waterscape can be planned in the water storage tank 6 to enhance the image of the sponge city. The rainwater is used again after being treated again through the treatment pipe 7 and the rainwater reprocessing equipment 8, so as to further improve the water quality of the purified rainwater, effectively reduce the content of impurities in the rainwater, and improve the water quality of the purified rainwater. It is convenient to provide water sources for green irrigation water, lakeside water, etc. after being purified again by the reprocessing mechanism to meet the standards, thereby improving the utilization efficiency of rainwater and preventing the waste of water resources.

[0066] Example 2

[0067] A method for a sponge city rainwater purification system, the steps comprising:

[0068] S1. Planning of rainwater purification system in sponge cities;

[0069] This system is planned in the rainwater gathering points, green plants and tree concentration areas of sponge cities. It is especially suitable for planning in green spaces, gardens and permeable pavements in sponge cities. It can effectively enhance the sponge city's ability to resist heavy rainfall, reduce the impact of heavy rainfall on sponge cities, prevent the occurrence of waterlogging in sponge cities, and improve the utilization efficiency of rainwater in sponge cities.

[0070] S2, regulation of water collection mechanism 2 during heavy rainfall;

[0071] When the sponge city encounters heavy rainfall, rainwater flows quickly into the rainwater well 1, and the gathered rainwater flows into the water collecting barrel 207 along the water collecting funnel 209. The rainwater in the water collecting barrel 207 cannot flow out along the leaking hole 208 in a short time, and the water level in the water collecting barrel 207 rises. Under the action of rainwater, the lifting float 211 rises along the water collecting trough through the floating wheel 212, and the lifting column 206 drives the grate side plate 210 to push the grate top plate 202 to rise. The lifting wheel 204 moves along the lifting groove, and the rainwater grate 201 protrudes from the wellhead of the rainwater well 1 as a whole. As the rainwater gathers towards the rainwater well 1, the debris in the sponge city gathers at the grate side plate 210, and the rainwater flows into the rainwater well 1 along the upper part of the grate side plate 210, which can not only prevent the rainwater grate 201 from being blocked, but also prevent the debris from blocking the inside of the rainwater well 1, causing the rainwater well 1 to fail and lose its drainage capacity.

[0072] The warning rod 203 connected to the lifting connecting rod 205 in the warning groove in the lifting groove rises with the grate side plate 210, and serves as a reminder after the rainwater grate 201 protrudes from the rainwater well 1, preventing vehicles or pedestrians from colliding with the rainwater grate 201 and avoiding accidents. The warning rod 203 is a bendable and flexible warning rod 203. When the warning rod 203 is hit or squeezed, the warning rod 203 bends, and the lifting connecting rod 205 squeezes the lifting spring 214 in the protective groove 213, so that the warning rod 203 retracts, thereby ensuring the safety of the warning rod 203 and the impact object.

[0073] S3, water purification mechanism 4 filters and purifies rainwater;

[0074] After being adjusted by the water collecting mechanism 2, the rainwater grate 201 can block a part of the debris, and the relatively short debris will flow into the rainwater well 1 along the rainwater grate 201, and the rainwater in the permeable pipe 3 will directly flow into the rainwater well. Under the action of the conical water leakage plate 406, the rainwater flows to the rainwater treatment structure in the water purification cylinder 401 for further treatment, and the conical water leakage plate 406 filters the debris in the rainwater again, and the debris slides along the conical water leakage plate 406 into the debris net bag 405 in the annular debris cylinder 404. After the debris is filtered by the debris net bag 405, the rainwater flows into the water purification cylinder 401 along the drainage hole 414; the dirt blocking oblique spikes 415 on the debris blocking teeth 412 can prevent the debris from overflowing the debris net bag 405 with the rainwater, thereby restraining the debris.

[0075] The rainwater filtered for the second time is further processed by the rainwater processing structure in the water purification cartridge 401. Specifically, the rainwater flows through the water purification port 417 on the water purification sleeve 416 in the water purification cartridge 401 along the water filter hole 410 to the water filter net bag, and the sundries and impurities in the rainwater are further filtered and purified, thereby further reducing the impurity content in the rainwater.

[0076] As the amount of rainwater flowing into the rainwater well 1 increases due to heavy rainfall, a large amount of rainwater gathers in the rainwater well 1, and the rainwater begins to gather at the bottom of the rainwater well 1. The rainwater enters the clean water regulating cylinder 420 along the vertical regulating hole on the side of the clean water regulating cylinder 420, and the hollow sleeve 422 generates buoyancy. At the same time, the lightweight regulating ball 418 on the regulating connecting rod 419 generates buoyancy under the action of rainwater at the bottom of the rainwater well 1. Under the buoyancy of the hollow sleeve 422 and the lightweight regulating ball 418, the adjusting pulley 421 of the hollow sleeve 422 rises along the adjusting chute, and the clean water sleeve 416 is pushed up by the adjusting vertical rod 411, and the clean water outlet 417 moves to the drain hole 409. The rainwater that has not been purified by the water filter bag begins to flow out quickly along the drain hole 409 to improve the water inlet efficiency of the rainwater well 1 and prevent natural disasters such as waterlogging in the sponge city.

[0077] As the rainwater in the rainwater well 1 continues to increase, the annular auxiliary cylinder 402 generates buoyancy under the action of the rainwater. Under the action of the buoyancy of the annular auxiliary cylinder 402, the annular auxiliary cylinder 402 pushes the annular debris cylinder 404 to move along the guide grooves on the clean water cylinder 401 and the rainwater well 1 through the guide magnetic strip 403. The guide magnetic strip 403 increases the friction with the guide groove by magnetic attraction to prevent the annular auxiliary cylinder 402 from rising or falling at will. As the annular auxiliary cylinder 402 rises, the annular debris cylinder 404 and There is a gap between the water purification cylinders 401, so rainwater can flow directly into the drainage pipe 5 without passing through the conical leaky plate 406, further improving the water inlet efficiency of the rainwater well 1 and reducing the amount of rainwater in the sponge city; in addition, the buoyancy generated by the annular auxiliary cylinder 402 drives the auxiliary cross bar 407 along the auxiliary adjustment hole 413 through the auxiliary connecting rod 408 to push the lifting column 206 to rise, thereby generating an auxiliary force on the rainwater grate 201, pushing the rainwater grate 201 to rise, and improving the entry efficiency of the rainwater grate 201.

[0078] S4. Reprocessing of rainwater;

[0079] The rainwater at the bottom of the rainwater well 1 is merged with the treated rainwater in the adjacent rainwater well 1 through the drainage pipe 5, and finally flows into the water storage tank 6. The city's distant waterscape can be planned in the water storage tank 6 to enhance the image of the sponge city. The rainwater is used again after being treated again through the treatment pipe 7 and the rainwater reprocessing equipment 8, so as to further improve the water quality of the purified rainwater, effectively reduce the content of impurities in the rainwater, and improve the water quality of the purified rainwater. It is convenient to provide water sources for green irrigation water, lakeside water, etc. after being purified again by the reprocessing mechanism to meet the standards, thereby improving the utilization efficiency of rainwater and preventing the waste of water resources.
