Description

Technical Field

[0001] This application relates to the field of rainwater irrigation technology, and in particular to a water storage and irrigation system for park green spaces based on sponge city construction. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept, which refers to a city that can be like a sponge, with good "elasticity" in adapting to environmental changes and responding to natural disasters. It adopts the methods of "source treatment" and "decentralized and centralized" to absorb, store, infiltrate and purify water when it rains, and release and utilize the stored water when needed, thereby optimizing the urban drainage system.

[0003] This "sponge" concept has also been applied to parks, where measures such as the construction of rain gardens, sunken green spaces, and artificial wetlands are used to enhance the urban sponge function of parks and green space systems and absorb their own rainwater.

[0004] Currently, green spaces in parks consume a large amount of public water resources every year. Utilizing natural rainwater to irrigate park green spaces saves a significant amount of water resources.

[0005] However, when rainwater accumulates or the 24-hour rainfall exceeds 50 millimeters, the debris cannot be effectively cleared, which will cause blockages and make it difficult to use rainwater later. Summary of the Invention

[0006] To reduce the likelihood of clogging in irrigation systems, this application provides a water storage and irrigation system for parks and green spaces based on sponge city construction.

[0007] The technical solution provided in this application for a park green space water storage and irrigation system based on sponge city construction is as follows:

[0008] A water storage and irrigation system for parks and green spaces based on sponge city construction includes an artificial wetland. Placement holes are provided in the artificial wetland, and a water collection cylinder is fixedly connected to each hole. The top of the water collection cylinder is aligned with the top of the artificial wetland. A water inlet grate is bolted to the top of the water collection cylinder. The water inlet grate has a hemispherical cross-section, and a scraper abuts against its outer surface. A driven shaft is rotatably connected to the water inlet grate. An abutting ring is fixedly connected to one end of the driven shaft near the water inlet grate, and the abutting ring abuts against the water inlet grate. The scraper abuts the end away from the artificial wetland, which is fixedly connected to the abutting ring. A connector is provided at the end of the driven shaft away from the abutting ring. A drive assembly is provided inside the water collection cylinder. The connector is located between the drive assembly and the driven shaft, with one end fixedly connected to the driven shaft and the other end fixedly connected to the drive assembly.

[0009] By adopting the above technical solution, when there is heavy rain or rainwater accumulation, rainwater enters the collection cylinder through the sluice grate. At this time, the drive component starts to work, transmitting power to the driven shaft through the connector, causing the driven shaft to rotate. The end of the driven shaft away from the connector is fixedly connected to an abutment ring, so that the driven shaft abuts against the sluice grate and does not fall into the collection cylinder. The outer surface of the sluice grate is fitted with a scraper that conforms to its arc surface, and the end of the scraper near the sluice grate is fixedly connected to the abutment ring, so that the scraper and the abutment ring rotate together. When the scraper rotates, it can effectively clean some impurities clogging the sluice grate, thus enabling the sluice grate to work normally and reducing the possibility of blockage in the irrigation system.

[0010] Optionally, the drive assembly includes a rotating cone, a rotating branch pipe, a rotating ring, and a drive shaft. The rotating cone has a conical cross-section, with an open large end and a closed small end. The large end of the rotating cone faces the sluice gate. The rotating ring is fixedly connected to the side of the rotating cone near the large end. A rotating groove is provided inside the water collecting cylinder, and the rotating cone and the water collecting cylinder rotate in cooperation. The rotating branch pipe is fixedly connected to the side of the rotating cone near the small end. Multiple rotating branch pipes are provided and are symmetrically arranged along the axis of the rotating cone. The drive shaft is fixedly connected inside the rotating cone. The drive shaft and the driven shaft are coaxial, and the end of the drive shaft away from the rotating cone is fixedly connected to a connector.

[0011] By adopting the above technical solution, the rotating ring is fixedly connected to the rotating cone, thereby allowing the rotating cone to be rotatably connected inside the water collection cylinder. When rainwater flows into the rotating cone through the drain grate, because the larger end of the rotating cone is open at the top and sealed at the smaller end at the bottom, the rainwater will concentrate inside the rotating cone. The rotating branch pipe fixedly connected to the smaller end of the rotating cone can drain the rainwater from inside the rotating cone. Since the diameter of the rotating branch pipe is smaller than the diameter at the smaller end of the rotating cone, when the rainwater flows out through the rotating branch pipe, the potential energy of the water flow causes the rotating cone to rotate, thereby causing the drive shaft fixedly connected to the bottom surface of the rotating cone to rotate. Through the connecting parts, the driven shaft rotates. Utilizing the potential energy of the rainwater to rotate the rotating cone not only saves resources but also avoids the short circuit caused by rainwater in conventional electric or pneumatic drive components.

[0012] Optionally, a guide pipe is fixedly connected inside the water collecting cylinder, and the cross-section of the guide pipe is hourglass-shaped. The guide pipe is located on the side near the large end of the rotating cone. A flow divider is fixedly connected inside the guide pipe. The cross-section of the flow divider is conical, and the bottom surface of the flow divider is near the large end of the rotating cone. Multiple spiral blades are fixedly connected to the rotating cone. The spiral blades are symmetrically arranged along the axis of the rotating cone, and the spiral direction of the spiral blades is consistent with the rotation direction of the rotating cone.

[0013] By adopting the above technical solution, multiple spiral blades symmetrically arranged along the center of the rotating cone further enhance the rotational effect of rainwater as it passes through the inner wall of the cone. The spiral direction of the blades must be consistent with the rotation direction of the cone. The guide pipe fixedly connected inside the collection cylinder further concentrates the rainwater, increasing its potential energy as it falls. The diversion platform guides and distributes rainwater between adjacent spiral blades, further improving the performance of the blades. This, in turn, improves the performance of the drive assembly.

[0014] Optionally, multiple balls are embedded in the rotating ring, and the balls are symmetrically arranged along the axis of the rotating ring. The balls abut against the rotating groove. A support frame is fixedly connected inside the water collecting cylinder. An abutting hemisphere is fixedly connected to the support frame. The abutting hemisphere is located on one side of the small end of the rotating cone. A ball groove is opened on the outer bottom surface of the rotating cone near the small end. The abutting hemisphere is embedded in the ball groove of the rotating cone and abuts against the rotating cone.

[0015] By adopting the above technical solution, the fixed support frame inside the water collecting cylinder reduces the impact of the rotating cone's own weight on its rotation. Furthermore, the support frame has a fixedly connected abutting hemisphere that abuts against the ball groove on the bottom surface of the rotating cone, reducing the friction between the rotating cone and the support frame. Multiple balls embedded in the rotating ring contact the rotating groove, further reducing the friction between the rotating ring and the water collecting cylinder, thereby further improving the performance of the drive assembly.

[0016] Optionally, a filter cone is provided at one end of the water collection cylinder near the water inlet grate. The filter cone has a smaller filter hole diameter than the water inlet grate. The filter cone has a conical cross-section. A guide block is fixedly connected to the larger end of the filter cone near the water inlet grate. A guide groove is provided on the water collection cylinder. The guide block and the guide groove are in sliding fit.

[0017] By adopting the above technical solution, a guide block is fixedly connected to the side of the filter cone near the water inlet grate, and a corresponding guide groove is opened on the water collection cylinder, allowing the filter cone to slide on the water collection cylinder. Furthermore, the diameter of the filter holes on the filter cone is smaller than the diameter of the filter holes on the water inlet grate, thereby further filtering impurities and further reducing the possibility of the irrigation system being clogged by impurities.

[0018] Optionally, a cleaning component is coaxially sleeved on the driven shaft. The cleaning component includes a brush and a rotating bracket. The rotating bracket is bolted to the driven shaft, and the brush is fixedly connected to the side of the rotating bracket near the filter cone. A positioning ring is sleeved on the driven shaft, and the rotating bracket abuts against the positioning ring, with the positioning ring located on one side of the small end of the filter cone.

[0019] By adopting the above technical solution, the cleaning component is sleeved on the driven shaft and located inside the filter cone. The cleaning component includes a rotating bracket and a brush. The rotating bracket is bolted to the driven shaft, so that it rotates together with the driven shaft. The brush is fixedly connected to the side of the rotating bracket near the filter cone, thereby reducing the possibility of the filter cone becoming clogged. The positioning ring fixedly connected to the driven shaft provides positioning for the worker when installing the rotating bracket, thereby improving the positional accuracy of the rotating bracket.

[0020] Optionally, the constructed wetland has a placement chamber, in which a sludge collection box is abutted. A filter sludge bucket is inserted into the water collection cylinder, with the outlet end of the filter sludge bucket facing the sludge collection box. A drive shaft is rotatably connected inside the filter sludge bucket, and a spiral auger is fixedly connected to the drive shaft. A protective box is detachably connected to the inner bottom surface of the end of the filter sludge bucket away from the sludge collection box. The protective box has a frustoconical cross-section, and a connecting component is located inside the protective box. The connecting component includes three bevel gears, which mesh with each other in pairs. The bevel gears are fixedly connected to the drive shaft, driven shaft, and drive shaft, respectively.

[0021] By adopting the above technical solution, a filter slag bin is installed inside the water collection cylinder, and a spiral auger is rotatably connected inside the filter slag bin. Rainwater entering the filter cone is further filtered, falling through the filter cone into the rotating cone, while impurities fall into the filter slag bin. Connecting components are located inside the filter slag bin, which is equipped with a protective box to further protect the connecting components and improve their service life. The connecting components include three bevel gears, which mesh with each other in pairs and are respectively fixedly connected to the drive shaft, driven shaft, and transmission shaft. When the drive shaft rotates under the rotation of the rotating cone, the meshing of the three bevel gears causes the transmission shaft and driven shaft to rotate as well. When the transmission shaft rotates, the spiral auger also rotates, causing impurities to collect in the slag collection box. When the slag collection box is full of impurities, operators can enter the placement chamber through the channel to clean out the impurities, facilitating unified collection.

[0022] Optionally, a baffle plate is fixedly connected inside the slag collection box, and the baffle plate divides the slag collection box into a sedimentation chamber and an overflow chamber, with the height of the baffle plate being lower than the height of the slag collection box.

[0023] By adopting the above technical solution, a baffle plate is fixedly connected inside the slag collection box. When impurities enter the slag collection box through the auger, rainwater is also present. The baffle plate inside the slag collection box separates the sediment into the settling chamber. When the amount of rainwater entering the settling chamber reaches a certain level, it will overflow into the chamber, thereby achieving solid-liquid separation.

[0024] Optionally, the placement chamber is equipped with a water collection tank, and the artificial wetland is equipped with a main water collection pipe. One end of the main water collection pipe is fixedly connected to the water collection cylinder, and the other end is connected to the water collection tank. The bottom surface of the overflow chamber is provided with a through hole, and a filter disc is detachably connected to the bottom surface of the overflow chamber. The artificial wetland is equipped with an overflow pipe, one end of which abuts against the inner bottom surface of the sludge collection box, and the other end is fixedly connected to the main water collection pipe. The overflow pipe and the through hole are coaxially arranged.

[0025] By adopting the above technical solution, a water collection tank is placed inside the chamber. Water in the water collection cylinder flows into the water collection tank through the main water collection pipe, thus facilitating rainwater collection and improving resource utilization. A through-hole is provided on the bottom surface of the overflow chamber, and a filter disc is detachably connected to the bottom surface of the overflow chamber. Rainwater overflowing into the overflow chamber flows into the main water collection pipe through the overflow pipe, and then collects in the water collection tank. The filter disc further reduces the possibility that the rainwater is free of impurities before entering the water collection tank.

[0026] Optionally, the water collection tank is provided with a placement port, and a detachable cap is connected to the placement port. The water collection tank is equipped with a water pump, and a water pump is detachably connected to the water pump. The artificial wetland is provided with multiple branch water pipes, and multiple nozzles are detachably connected to the branch water pipes. The nozzles are equidistantly arranged along the path of the branch water pipes, and all branch water pipes can be detachably connected to the water pump.

[0027] By adopting the above technical solution, the inlet on the water collection tank can be used for simple disinfection and cleaning of the rainwater in the tank. When water is needed, the water pump is started, and the rainwater is pumped through the water pipe to the various branch water pipes on the constructed wetland, and then irrigated through the sprinklers, further improving the resource utilization rate.

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

[0029] 1. During heavy rain or rainwater accumulation, rainwater enters the collection cylinder through the sluice grate. At this time, the drive assembly starts working, transmitting power to the driven shaft through the connector, causing the driven shaft to rotate. A retaining ring is fixedly connected to the end of the driven shaft away from the connector, thus keeping the driven shaft against the sluice grate and preventing it from falling into the collection cylinder. A scraper blade, conforming to the grate's arc, is fitted to the outer surface of the sluice grate, with its end near the grate fixedly connected to the retaining ring. The scraper blade and retaining ring rotate together. When the scraper blade rotates, it effectively clears debris clogging the sluice grate, ensuring its normal operation and reducing the likelihood of blockages in the irrigation system.

[0030] 2. A rotating ring is fixedly connected to a rotating cone, thus allowing the rotating cone to rotatably connect to the water collection cylinder. When rainwater flows into the rotating cone through the drain grate, because the larger end of the rotating cone is open at the top and the smaller end is sealed at the bottom, the rainwater will concentrate inside the rotating cone. The rotating branch pipe fixedly connected to the smaller end of the rotating cone can drain the rainwater from inside the cone. Since the diameter of the rotating branch pipe is smaller than the diameter at the smaller end of the rotating cone, when rainwater flows out through the rotating branch pipe, the potential energy of the water flow causes the rotating branch pipe to rotate, thereby causing the drive shaft fixedly connected to the ground inside the rotating branch pipe to rotate. This, in turn, causes the driven shaft to rotate through the connecting parts. By utilizing the potential energy of the rainwater to rotate the rotating cone, not only are resources saved, but the effects of short circuits caused by rainwater on conventional electric or pneumatic drive components are also avoided.

[0031] 3. The fixed support frame inside the water collection cylinder reduces the impact of the rotating cone's own weight on its rotation. A fixed abutting hemisphere on the support frame abuts against a groove on the bottom of the rotating cone, further reducing friction between the rotating cone and the support frame. Multiple balls embedded in the rotating ring contact the rotating groove, reducing friction between the rotating ring and the water collection cylinder, thereby further improving the performance of the drive assembly.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a water storage and irrigation system for parks and green spaces based on sponge city construction.

[0040] Reference Figures 1 to 5 A water storage and irrigation system for park green spaces based on sponge city construction includes an artificial wetland 1. The artificial wetland 1 has a placement hole 11, and a water collection cylinder 2 is placed in the placement hole 11. After the construction workers place the water collection cylinder 2 in the placement hole 11, they fix the water collection cylinder 2 in the placement hole 11 with soil and cement, and align the top of the water collection cylinder 2 with the artificial wetland 1. The artificial wetland 1 has a placement cavity 12, and a water collection pool 9 is fixedly connected in the placement cavity 12. A water collection main pipe 14 is passed through the end of the water collection cylinder 2 away from the water inlet. The water collection main pipe 14 is pre-buried in the artificial wetland 1, and one end is fixedly connected to the water collection cylinder 2, and the other end is fixedly connected to the water collection pool 9. A sprue 21 is bolted to one end of the water collecting cylinder 2 near the inlet. The sprue 21 has a hemispherical cross-section, and a scraper 22 abuts against its outer surface. The scraper 22 is in contact with the sprue 21 on the side closest to it, and its cross-section is an isosceles trapezoid. A driven shaft 211 is rotatably connected to the sprue 21, and an abutment ring 212 is fixedly connected to the driven shaft 211. The abutment ring 212 is located at one end near the sprue 21, and the end of the scraper 22 near the abutment ring 212 is fixedly connected to the abutment ring 212. A drive assembly 4 is provided inside the water collecting cylinder 2. A connector 3 is provided between the drive assembly 4 and the driven shaft 211. One end of the drive assembly 4 is fixedly connected to the driven shaft 211, and the other end is fixedly connected to the drive assembly 4.

[0041] Reference Figures 1 to 5 When it rains, rainwater enters the collection cylinder 2 through the grate 21. The grate 21 blocks impurities, but its outer surface is easily clogged by these impurities. When rainwater enters the collection cylinder 2, the drive assembly 4 operates, rotating the driven shaft 211 via the connector 3. The abutment ring 212 and the scraper 22 fixedly connected to it also rotate. As the scraper 22 rotates, it cleans the impurities from the outer surface of the grate 21, allowing rainwater to flow normally into the collection cylinder 2. This reduces the likelihood of clogging in the irrigation system. After entering the collection cylinder 2, the rainwater flows through the main collection pipe 14 to the collection tank 9, thus collecting the rainwater for subsequent irrigation of the constructed wetland 1, achieving rainwater recycling.

[0042] Reference Figure 2 and Figure 3 The drive assembly 4 includes a rotating cone 41, a rotating branch pipe 42, a rotating ring 43, and a drive shaft 44. The rotating cone 41 has a conical cross-section. The larger end of the rotating cone 41 faces the sluice grate 21 and is open, while the smaller end is closed away from the sluice grate 21. The rotating ring 43 is fixedly connected to the larger end of the rotating cone 41. A rotating groove 23 is provided on the water collecting cylinder 2, and the rotating ring 43 is rotatably connected in the rotating groove 23, thereby rotatably connecting the rotating cone 41 to the water collecting cylinder 2.

[0043] Reference Figure 2 and Figure 3 The drive shaft 44 is fixedly connected to the inner bottom surface of the small port of the rotating cone 41, and multiple rotating branch pipes 42 are fixedly connected near the small port of the rotating cone 41. They are symmetrically arranged along the axis of the rotating cone 41. The end of the drive shaft 44 away from the rotating cone 41 is fixedly connected to the connector 3.

[0044] Reference Figure 2 and Figure 3When rainwater enters the water collection cylinder 2 through the grate 21, it flows into the rotating cone 41 and then out through the rotating branch pipe 42. Since the diameter of the large port of the rotating cone 41 is larger than the diameter of its small port, and the diameter of its small port is larger than the diameter of the rotating branch pipe 42, the potential energy generated when the rainwater flows into the rotating cone 41 and then out through the rotating branch pipe 42 causes the rotating cone 41 to rotate. The drive shaft 44, fixedly connected inside the rotating cone 41, also rotates accordingly. This not only saves water resources but also avoids the short circuits caused by rainwater on conventional electric or pneumatic drive components, thus reducing the risk of future maintenance. When the drive shaft 44 rotates, the driven shaft 211 rotates through the connector 3, causing the scraper 22 to rotate on the outer surface of the grate 21.

[0045] Reference Figure 2 and Figure 3 Multiple spiral blades 411 are fixedly connected inside the rotating cone 41, and the spiral direction of the spiral blades 411 is consistent with the rotation direction of the rotating cone 41. A guide pipe 5 is fixedly connected inside the water collecting cylinder 2 near the large end of the rotating cone 41. The guide pipe 5 has an hourglass-shaped cross-section. A flow divider 51 is fixedly connected inside the guide pipe 5 near the large port of the rotating cone 41, and the flow divider 51 has a conical cross-section. The guide pipe 5 is located between the water inlet grate 21 and the rotating cone 41.

[0046] Reference Figure 2 and Figure 3 Before entering the rotating cone 41, rainwater needs to pass through the guide pipe 5. The guide pipe 5 can concentrate the dispersed rainwater, and the diverting platform 51 fixedly connected inside the guide pipe 5 disperses the concentrated rainwater around the periphery of the guide pipe 5. At this time, the spiral blades 411 fixedly connected inside the rotating cone 41, under the action of the guide pipe 5 and the diverting platform 51, cause the rainwater to wash over their surface, thereby increasing the rotation effect of the rotating cone 41.

[0047] Reference Figure 3 and Figure 5 A plurality of ball bearings 431 are provided on the side of the rotating ring 43 near the rotating groove 23. The ball bearings 431 are embedded in the rotating ring 43 and are symmetrically arranged along the center of the rotating ring 43. A support frame 24 is provided near the bottom of the rotating cone 41. The support frame 24 is fixedly connected to the water collecting cylinder 2. A ball groove 412 is opened on the outer bottom surface of the small port of the rotating cone 41. An abutting hemisphere 241 is fixedly connected to the side of the support frame 24 near the small port of the rotating cone 41. The abutting hemisphere 241 is embedded in the ball groove 412.

[0048] Reference Figure 3 and Figure 5The support frame 24 reduces the impact of the rotating cone 41's own weight on its rotation. When the rotating cone 41 rotates, the multiple balls 431 make point contact with the rotating groove 23, thereby reducing the friction between the rotating cone 41 and the rotating groove 23. Furthermore, the abutting hemisphere 241 on the support frame 24 abuts against the ball groove 412 on the rotating cone 41, and a certain gap is maintained between the support frame 24 and the rotating cone 41, further reducing the friction generated when the rotating cone 41 rotates.

[0049] Reference Figure 2 and Figure 3 A filter cone 6 is provided at one end of the water collecting cylinder 2 near the water inlet grate 21. The filter cone 6 is conical in shape, and the diameter of its filter holes is smaller than the diameter of the filter holes of the water inlet grate 21. A guide groove 25 is provided on the end of the water collecting cylinder 2 near the water inlet grate 21. A guide block 61 is slidably connected in the guide groove 25. The guide block 61 is fixedly connected to the filter cone 6, thereby allowing the filter cone 6 to be slidably connected inside the water collecting cylinder 2.

[0050] Reference Figure 2 and Figure 3 When rainwater enters the water collection cylinder 2 through the grate 21, it first passes through the filter cone 6. Since the grate 21 contains silt and sand, which could increase the likelihood of clogging the irrigation system, the filter cone 6 further filters out impurities such as silt and stones, thus reducing the possibility of clogging. The cooperation between the guide block 61 and the guide groove 25 facilitates the fixation of the filter cone 6.

[0051] Reference Figure 2 and Figure 3 The filter cone 6 is equipped with a cleaning assembly 62. The cleaning area includes a brush 621 and a rotating bracket 622. The rotating bracket 622 is bolted to the driven shaft 211, and the brush 621 is fixedly connected to the rotating bracket 622 and located on the side close to the filter cone 6. A positioning ring 213 is coaxially sleeved on the driven shaft 211. The positioning ring 213 abuts against the rotating bracket 622, and the positioning ring 213 is located on the side away from the large end of the filter cone 6.

[0052] Reference Figure 2 and Figure 3 When rainwater passes through the drain grate 21, the existing silt can easily clog the filter holes inside the filter cone 6. By bolting the rotating bracket 622 to the rotating shaft, the driven shaft 211 rotates together with the rotating shaft, thus cleaning the air filter holes of the filter cone 6 and reducing the possibility of clogging due to silt. The positioning ring 213 facilitates quick positioning by the operator, thereby improving installation efficiency.

[0053] Reference Figures 2 to 4A slag collection box 7 is located inside the placement cavity 12, and a filter slag bucket 8 is installed inside the water collection cylinder 2. The filter slag bucket 8 is located between the filter cone 6 and the guide pipe 5. A drive shaft 81 is rotatably connected inside the filter slag bucket 8, and the outlet end of the filter slag bucket 8 is directly opposite the slag collection box 7 inside the placement cavity 12. A spiral auger 82 is fixedly connected to the drive shaft 81, and a protective box 83 is fixedly connected to the side of the filter slag bucket 8 away from the slag collection box 7. A connecting member 3 is located inside the protective box 83. The connecting member 3 includes three bevel gears 31, which mesh with each other in pairs. The bevel gears 31 are respectively connected to the drive shaft 44, the driven shaft 211, and the drive shaft 81.

[0054] Reference Figures 2 to 4 When the drive shaft 44 rotates, it causes the driven shaft 211 and the transmission shaft 81 to rotate via the bevel gear 31. When the transmission shaft 81 rotates, the auger 82 also rotates, allowing soil and impurities to reach the slag collection box 7. When the slag collection box 7 is full, workers can enter the placement chamber 12 through the passage to clean the impurities, facilitating unified collection and improving work efficiency. The design of the protective box 83 primarily increases the service life of the connecting piece 3.

[0055] Reference Figure 2 and Figure 4 A baffle plate 71 is fixedly connected inside the slag collection box 7, dividing the slag collection box 7 into a sedimentation chamber 72 and an overflow chamber 73. The outlet end of the filter slag bucket 8 is directly opposite the sedimentation chamber 72, and the height of the baffle plate 71 is lower than the height of the slag collection box 7. A through hole 731 is opened in the inner ground of the overflow chamber 73, and a filter disc 732 is detachably connected inside the through hole 731. An overflow pipe 141 is pre-embedded in the artificial wetland 1. One end of the overflow pipe 141 abuts against the inner bottom surface of the slag collection box 7, and the other end is fixedly connected to the main water collection pipe 14.

[0056] Reference Figure 2 and Figure 4 Because the irrigation system is located on the park's green space, when it rains, the soil flows into the collection cylinder 2 along with the rainwater. After passing through the filter cone 6, the soil is collected by the spiral auger 82 into the sedimentation chamber 72 inside the sludge collection box 7, while rainwater also enters the sludge collection box 7. The baffle plate 71, which is fixedly connected inside the sludge collection box 7, separates the soil. After sedimentation, when the water level exceeds the baffle plate 71, it flows into the overflow chamber 73, and then through the overflow pipe 141, the water is collected into the main water collection pipe 14, and then flows into the collection pool 9.

[0057] Reference Figure 1 and Figure 2The water collection tank 9 has a placement port 91, which is detachably connected to a screw cap 911. Since rainwater may contain other liquid impurities that could cause it to smell, the placement port 91 allows for simple disinfection and cleaning of the water collection tank 9. The water collection tank 9 is equipped with a water pump 92, which is detachably connected to a pumping pipe 921. The artificial wetland 1 has multiple branch water pipes 13, each detachably connected to a sprinkler head 131. The sprinkler heads 131 are equidistantly arranged along the path of the branch water pipes 13.

[0058] Reference Figure 1 and Figure 2 When irrigation is needed for the artificial wetland 1, the water pump 92 is started. The rainwater in the collection tank 9 flows through the pumping pipe 921 to the branch water pipes 13, and then from the branch water pipes 13 to the sprinkler heads 131, thereby realizing the recycling of water resources and further improving the utilization rate of water resources.

[0059] The implementation principle of a park green space water storage and irrigation system based on sponge city construction in this application embodiment is as follows:

[0060] When there is heavy rain or rainwater accumulation, the rainwater enters the water collection cylinder 2 through the water inlet grate 21. The water inlet grate 21 performs the first filtration of the rainwater, mainly filtering out leaves.

[0061] When rainwater enters the collection cylinder 2, it first passes through the filter cone 6, which is a secondary filtration process, mainly removing soil. The soil will remain in the filter cone 6, while the rainwater will pass through the filter holes of the filter cone 6, through the guide pipe 5, and then into the rotating cone 41.

[0062] After passing through the filter cone 6, the soil reaches the filter residue bin 8. Then, the spiral auger 82 inside the filter residue bin 8 directs the impurities to the sedimentation chamber 72 within the slag collection box 7. After a period of time, when the rainwater level in the sedimentation chamber 72 exceeds the baffle plate 71, the rainwater in the sedimentation chamber 72 flows into the overflow chamber 73. This allows the rainwater in the overflow chamber 73 to flow through the overflow pipe 141 into the main water collection pipe 14, and then into the collection pool 9. This saves water resources and further improves water resource utilization.

[0063] After rainwater passes through the filter cone 6 and reaches the guide pipe 5, the diversion platform 51 inside the guide pipe 5 causes the rainwater to diffuse circumferentially, thereby further improving the rotational capacity of the rotating cone 41. The spiral 411 blades, which are fixedly connected and symmetrically arranged along the axis of the rotating cone 41, further improve the rotational capacity of the rotating cone 41.

[0064] When rainwater enters the rotating cone 41, the potential energy generated as the rainwater flows out of the rotating branch pipe 42, due to the larger diameter of the larger port than the smaller port, and the smaller port being larger than the rotating branch pipe 42, causes the cone 41 to rotate. The drive shaft 44, fixedly connected inside the cone 41, also rotates. Connecting parts 3, consisting of three bevel gears 31, are fixedly connected to the drive shaft 44 and mesh with each other in pairs. Therefore, when the drive shaft 44 rotates, the driven shaft 211 and the transmission shaft 81 also rotate. This connection between the three bevel gears 31 not only saves resources but also avoids the short circuits caused by rainwater in conventional electric or pneumatic drive components, thus reducing the risk of future maintenance.

[0065] The ball bearings 431 on the rotating ring 43 and the contact hemisphere 241 reduce the friction generated by the rotating cone 41 during rotation, further improving its performance.

[0066] After rainwater flows out from the rotating branch pipe 42, it passes through the main collection pipe 14 and reaches the collection tank 9. When irrigation of the constructed wetland 1 is required, the water pump 92 is started, causing the rainwater in the collection tank 9 to flow through the pumping pipe 921 to each branch pipe 13, and then be evenly sprayed onto the constructed wetland 1 through the sprinkler head 131. This achieves irrigation of the constructed wetland 1 and further improves resource utilization.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
