Description

Technical Field

[0001] The present application relates to the technical field of water circulation, and in particular to a green space multi-layer graded water purification circulation system. Background Art

[0002] Currently, green spaces are often installed along the sides of roads, with their elevation lower than the surrounding ground. This allows rainwater from surrounding roads to be diverted to the green spaces for accumulation and infiltration during rainy days, thereby reducing runoff. However, green spaces have limited water absorption capacity and speed. During heavy rain, the rate of rainwater infiltration is slower than the rate of accumulation on the green space surface. This can lead to excessive water accumulation in the green space, which can then overflow onto the road and affect drainage. Summary of the Invention

[0003] In order to prevent rainwater from flooding onto the road, the present application provides a multi-layer graded water purification circulation system for green space.

[0004] This application provides a green space multi-layer graded water purification circulation system, which adopts the following technical solutions:

[0005] A multi-layer graded water purification circulation system for green space includes a water infiltration unit and a water collection unit. The surface of the water infiltration unit has vegetation. The water collection unit includes a water collection box and a diversion pipe. The water collection box is located at the bottom of the water infiltration unit. One end of the diversion pipe extends out of the surface of the water infiltration unit and is open. The other end of the diversion pipe is connected to the water collection box, so that the water accumulated on the water infiltration unit can be guided into the water collection box through the diversion pipe.

[0006] By adopting the above technical solution, when rainwater accumulates on the seepage unit and overflows to the end of the diversion pipe, the rainwater can enter the diversion pipe from the opening of the diversion pipe and enter the water collecting tank through the diversion pipe for collection. As a result, the rainwater can be discharged from the diversion pipe while gradually seeping down in the seepage unit, thereby improving the discharge efficiency of rainwater on the seepage unit and making it less likely for rainwater to overflow to the surrounding roads.

[0007] Optionally, there are multiple diversion pipes, all of which are located at one end of the water collecting tank and are connected to the same main pipe; a partition is provided in the water collecting tank, the partition divides the inner cavity of the water collecting tank into an installation cavity and a water collecting cavity arranged upper and lower, and the main pipe is located in the installation cavity;

[0008] The water collecting chamber is provided with a water supply pipe and a water delivery pipe, one end of the water supply pipe and the water delivery pipe extends to the bottom of the water collecting chamber, and the other end of the water supply pipe and the water delivery pipe passes through the partition and enters the installation chamber, and a valve is connected between the main pipe, the water supply pipe and the water delivery pipe to connect the main pipe with the water supply pipe or the water delivery pipe, and the water delivery pipe is provided with a power source, and when the main pipe is connected with the water delivery pipe, the power source is used to direct the water flow in the water collecting chamber through the water delivery pipe and the main pipe in sequence into the guide pipe.

[0009] By adopting the above technical solution, when it rains, the gate is operated to connect the main pipe with the water supply pipe, so that the water discharged from the seepage unit into the diversion pipe can enter the main pipe from the diversion pipe, then enter the water supply pipe from the main pipe, and then enter the water collection chamber from the water supply pipe for collection. When it is necessary to water the vegetation on the seepage unit, the gate is operated to connect the main pipe with the water supply pipe. The power source can pump the accumulated water in the water collection chamber to the water supply pipe, and then transport the water to each diversion pipe through the water supply pipe, and then flow out from the end of the diversion pipe located outside the seepage unit to water the vegetation on the seepage unit, thereby recycling rainwater.

[0010] Optionally, the guide pipe has a plurality of through holes on the pipe wall in the seepage unit, and the guide pipe has an organ pipe connected to the guide pipe, one end of the organ pipe is fixed to the guide pipe, and the other end of the organ pipe moves in the guide pipe along the axis of the guide pipe to cover or expose the through holes, and the guide pipe has a driving component for driving the organ pipe to move.

[0011] By adopting the above technical solution, the through-holes enable water flow exchange between the diversion pipe and the water seepage unit, so that when the water collection chamber is full, water can be discharged into the water seepage unit. When the water seepage unit reaches its limit, water is discharged into the diversion pipe through the through-holes, and then the diversion pipe guides water into the water collection chamber. The exposure and obstruction of the through-holes by the organ pipes allows the diversion pipe to simultaneously transport water from the water collection chamber to the other end of the diversion pipe away from the water collection tank while also transporting water into the water collection chamber.

[0012] Optionally, the guide tube includes a first section, a rotating section, and a second section connected in sequence, the rotating section is rotatably connected between the first section and the second section, the rotating section and the second section are located in the installation cavity, the first section extends into the water seepage unit, the inner wall of the first section is connected to a connecting seat, and the inner wall of the rotating section is connected to a rotating seat; the driving assembly includes,

[0013] a screw, one end of which is rotatably connected to the connecting seat, the other end of which is fixedly connected to the rotating seat, and is coaxially arranged with the first section and the rotating section;

[0016] The rotating member cooperates with the rotating section to drive the rotating section to rotate.

[0017] By adopting the above technical solution, the rotating section is driven to rotate by the rotating member, so that the rotating section can drive the screw to rotate together through the rotating seat, so that the moving seat moves along the axial direction of the screw under the guidance of the guide member to drive the organ pipe to expand or compress.

[0018] Optionally, the rotating member includes a ring, a mating seat and a rotation source, the ring is coaxially sleeved on the outer wall of the rotating section, the mating seat is rotatably connected to the installation cavity of the water collecting tank, the outer wall of the ring is provided with first teeth along its own circumference, the mating seat is provided with second teeth along its own circumference, and the second teeth of the mating seat are simultaneously engaged with the first teeth of all the rings, and the rotation source is used to drive the mating seat to rotate.

[0019] By adopting the above technical solution, the rotation source drives the matching seat to rotate, and the matching seat drives all the rotating sections to rotate together due to the engagement of the first teeth and the second teeth, so that the screws in all the guide tubes rotate together, thereby driving the moving seat to move along the screw axis.

[0020] Optionally, the guide pipe has a nozzle at one end away from the water collecting tank, the nozzle has a water inlet, and the nozzle has a plurality of water outlet holes connected to the water inlet;

[0021] There is a linkage between the nozzle and the movable seat. When the organ pipe blocks the through hole, the nozzle and the guide pipe are pressed against each other, and the water inlet is connected to the guide pipe. When the organ pipe exposes the through hole, the nozzle is separated from the guide pipe in a direction away from the guide pipe.

[0022] By adopting the above technical solution, the arrangement of the nozzle can enable the water to be sprayed from the diversion pipe and sprayed to various places on the vegetation in the infiltration unit through the guidance of the nozzle, so as to improve the watering effect on the vegetation.

[0023] Optionally, the linkage includes a mounting box, a first rack, a gear and a second rack. The mounting box is installed in the first section and is hollow inside.

The first rack and the second rack both move and extend into the mounting box, and the first rack and the second rack are respectively engaged with the opposite sides of the gear.

[0024] By adopting the above technical solution, when the movable seat moves, it drives the first rack to move, thereby driving the gear to rotate, and then driving the second rack to move, so as to realize the movement of the nozzle, so that the nozzle and the first section are offset or separated.

[0025] Optionally, a rotation-stopping frame is connected between the first section and the second section, and the rotation-stopping frame limits the relative rotation of the first section and the second section.

[0043] The following is combined with Figure 1-9 This application is described in further detail.

[0044] The present application embodiment discloses a green space multi-layer graded water purification circulation system. Figure 1 The green space multi-layer graded water purification circulation system includes a water seepage unit 1 and a water collection unit 2 arranged above and below.

[0045] The seepage unit 1 includes a soil layer 101, a gravel layer 102, and a pebble layer 103 stacked sequentially from top to bottom. The particle size of the soil layer 101, the gravel layer 102, and the pebble layer 103 gradually increases, and green vegetation is planted on the soil layer 101. The water collection unit 2 includes a water collection tank 201 and a diversion pipe 202. The water collection tank 201 is located at the bottom of the pebble layer 103 to support the pebble layer 103. The water collection tank 201 has a directional box structure and a hollow inner cavity. The diversion pipe 202 is in the shape of a circular tube, and one end of the diversion pipe 202 extends into the water collection tank 201 and communicates with the inner cavity of the water collection tank 201. The other end of the diversion pipe 202 extends through the seepage unit 1 to the upper part of the soil layer 101. The two ends of the diversion pipe 202, which are separated from each other, are open, and the top of the diversion pipe 202 is lower than the elevation of the road surrounding the soil layer 101.

[0046] When rainwater accumulates on the soil layer 101 and does not seep in time, and when the rainwater accumulates to the height of the top of the diversion pipe 202, the rainwater can enter the diversion pipe 202 from the top of the diversion pipe 202, and enter the water collecting tank 201 through the diversion pipe 202 and accumulate in the water collecting tank 201, so that the rainwater is not easy to overflow to the road around the soil layer 101.

[0047] Reference Figure 2 and Figure 3 To improve the efficiency of rainwater entering the water collection tank 201, multiple diversion pipes 202 are provided. In this embodiment, there are six diversion pipes 202, distributed in a circular pattern along the midpoint of the water collection tank 201. The water collection tank 201 includes a main pipe 3, which is circular and has an inner diameter larger than that of the diversion pipes 202. The main pipe 3 is located at the midpoint of the water collection tank 201. The ends of all diversion pipes 202 located within the water collection tank 201 extend downwardly, tilted toward the main pipe 3, and are fixedly connected to and in communication with the main pipe 3. This ensures that rainwater flowing from the diversion pipes 202 flows into the main pipe 3, and then from there into the water collection tank 201. The connections between all diversion pipes 202 and the main pipe 3 are located on the same horizontal plane.

[0048] Reference Figure 2 and Figure 3 Furthermore, in order to facilitate the utilization of the accumulated water in the water collecting tank 201, a partition 4 is fixed in the water collecting tank 201 to separate the inner cavity of the water collecting tank 201. The plate surface of the partition 4 is in a horizontal state. The partition 4 divides the inner cavity of the water collecting tank 201 into an installation cavity 5 and a water collecting cavity 6 arranged upper and lower. The installation cavity 5 is located above the water collecting cavity 6, and the water collecting tank 201 is provided with a pressure equalizing hole on the upper side walls of the installation cavity 5 and the water collecting cavity 6 to balance the air pressure inside and outside the water collecting tank 201.

[0049] The main pipe 3 is located within the installation chamber 5. The axis of the main pipe 3 extends vertically, with the upper end of the main pipe 3 closed and the lower end open. A gate is connected to the lower end of the main pipe 3. The gate is a three-way solenoid valve with one inlet and two outlets. An external power supply can control the connection between the inlet and either outlet. The power supply for the gate passes through the water collection tank 201 and the seepage unit 1 and is connected to a control room (not shown) outside the soil layer 101. The gate is installed within the installation chamber 5. The two outlets of the gate are respectively connected to a water supply pipe 7 and a water supply pipe 8. The end of the water supply pipe 7 away from the gate is fixedly inserted through the partition 4 and extends to the upper part of the water collection chamber 6. The end of the water supply pipe 8 away from the gate is fixedly inserted through the partition 4 and extends to the bottom of the water collection chamber 6. The gate controls the main pipe 3 to connect to the water supply pipe 7 or the water supply pipe 8. The portion of the water supply pipe 8 within the installation chamber 5 is also equipped with a power source 10 for pumping water. The power source 10 is a water pump, and the power supply for the water pump is also connected to the control room.

[0050] When it rains, the gate is operated to connect the main pipe 3 with the water supply pipe 7. At this time, rainwater enters the main pipe 3 through the diversion pipe 202, then enters the water supply pipe 7 from the main pipe 3, and then enters the water collection chamber 6 of the water collection tank 201 for collection. When the rain stops and it is necessary to water the vegetation on the soil layer 101, the gate is operated to connect the main pipe 3 with the water supply pipe 8, and the water pump is started. The water pump pumps the accumulated water in the water collection chamber 6 through the water supply pipe 8 and the main pipe 3 into each diversion pipe 202 in sequence, so that the accumulated water flows out from the top of the diversion pipe 202 to irrigate the vegetation.

[0051] Reference Figure 2 and Figure 4 In order to prevent impurities and soil in the rainwater from entering the guide pipe 202 with the rainwater, a filter screen 27 is installed at the top opening of the guide pipe 202 to preliminarily filter the rainwater entering the guide pipe 202 from the top. In addition, an activated carbon bag is placed in the water collection chamber 6 to adsorb impurities in the rainwater entering the water collection chamber 6 and further filter the rainwater. The water collection box 201 has an operation port at the water collection chamber 6 that is connected to the inside of the water collection chamber 6. Figure 1 The water collecting box 201 is detachably connected to an opening and closing door 28 at the operating port for opening and closing the operating port, and the outside of the seepage unit 1 is provided with an inspection passage (not shown in the figure) that can be moved to the operating port, so as to enter the water collecting chamber 6 through the inspection passage and the operating port to replace the activated carbon bag.

[0052] Reference Figure 1 and Figure 5Furthermore, in order to improve the rainwater storage capacity of the seepage unit 1, a plurality of through holes 11 are arranged in an array on the pipe wall of the guide pipe 202 in the pebble layer 103, and the outer wall of the guide pipe 202 with the through holes 11 is covered with gauze 26. In the process of rainwater seeping from the diversion pipe 202, part of the rainwater can enter the pebble layer 103 through the through hole 11 for accumulation; or when the rainwater accumulates in the water collection chamber 6, the rainwater accumulates in the diversion pipe 202 to the pebble layer 103, and the rainwater in the pebble layer 103 is not yet full, the rainwater can enter the pebble layer 103 through the through hole 11; or when the pebble layer 103 is filled with rainwater seeping from the upper layer, and the water collection chamber 6 is not full, the accumulated water in the pebble layer 103 can be filtered by the gauze 26 and then enter the diversion pipe 202 through the through hole 11, and then enter the water collection chamber 6 from the diversion pipe 202 for accumulation.

[0053] Reference Figure 5 and Figure 6 When water in the water collection chamber 6 is pumped to irrigate vegetation, the water flow is less likely to be affected by the through-hole 11 and overflows entirely from the through-hole 11. The diversion tube 202 includes an organ pipe 12 in communication with the diversion tube 202. The two opposing ends of the organ pipe 12 are connected and communicate with the diversion tube 202. One end of the organ pipe 12 is fixed to the inner wall of the diversion tube 202, while the other opposite end of the organ pipe 12 moves within the diversion tube 202 along its axis to expand or contract the organ pipe 12. To drive the movement of the organ pipe 12, the diversion tube 202 includes a drive assembly.

[0054] When the organ pipe 12 is compressed, the organ pipe 12 exposes the through holes 11 so that water can be exchanged between the guide tube 202 and the pebble layer 103; when the organ pipe 12 is expanded, the organ pipe 12 blocks all the through holes 11 so that the water drawn from the guide tube 202 can flow out from the upper end of the guide tube 202, and the water drawn upward by the guide tube 202 during the expansion process of the organ pipe 12 can be sprayed out from the through holes 11 that are not blocked in the upper part of the organ pipe 12, so as to flush the gauze 26 from the inside to the outside, clean the gauze 26, and reduce the possibility of the gauze 26 being blocked.

[0055] Reference Figure 2 and Figure 5 Specifically, the flow guide tube 202 includes a first section 2021, a rotating section 2022 and a second section 2023 that are sequentially connected and communicated. Figure 1The two ends of the first section 2021 that are far away from each other are respectively located on the upper part of the soil layer 101 and in the installation cavity 5, the rotating section 2022 and the second section 2023 are both located in the installation cavity 5, the rotating section 2022 is rotatably connected between the first section 2021 and the second section 2023, and the axes of the first section 2021, the rotating section 2022 and the second section 2023 close to one end of the rotating section 2022 all extend in the vertical direction, and the rotating section 2022 is coaxial with the first section 2021 and the second section 2023.

[0056] Reference Figure 5 and Figure 6 A rotating seat 14 is fixed to the inner wall of the rotating section 2022, and a connecting seat 13 is fixed to the inner wall of the first section 2021. Both the rotating seat 14 and the connecting seat 13 are hollow. A rotation stop 25 is connected between the first section 2021 and the second section 2023. The two ends of the rotation stop 25 are fixed to the first section 2021 and the second section 2023 respectively, so that the first section 2021 and the second section 2023 cannot rotate relative to each other.

[0057] Reference Figure 6 and Figure 7 The driving assembly includes a screw 15, a movable base 16, a guide member 17, and a rotating member 18. The top end of the screw 15 is rotatably connected to the center of the connecting base 13, the bottom end of the screw 15 is fixed to the center of the rotating base 14, and the screw 15 is coaxially arranged with the rotating section 2022.

[0058] Reference Figure 5 and Figure 6 The bottom end of the organ pipe 12 has a fixed seat 29. The fixed seat 29 is annular in shape with an outer diameter that matches the inner diameter of the first section 2021 and is fixed to the inner wall of the first section 2021. The fixed seat 29 closes the space between the circumferential outer wall of the bottom of the organ pipe 12 and the inner wall of the first section 2021, so that when water flows to the fixed seat 29, it passes through the organ pipe 12. The movable seat 16 is fixed to the top of the organ pipe 12 and has a hollow shape. The movable seat 16 slides coaxially up and down within the first section 2021. The movable seat 16 closes the space between the outer wall of the top of the organ pipe 12 and the inner wall of the first section 2021, so that water cannot easily enter the space enclosed by the outer wall of the organ pipe 12, the fixed seat 29, the enclosing seat, and the inner wall of the first section 2021.

[0059] Reference Figure 6 and Figure 7At the same time, the movable seat 16 is coaxially threadedly sleeved on the outer wall of the screw 15, and the guide member 17 is disposed between the movable seat 16 and the guide tube 202, which is used to drive the movable seat 16 to move only axially along the first section 2021 and prevent relative rotation between the movable seat 16 and the fixed seat 29. The rotating member 18 is installed in the installation cavity 5 and is used to drive the rotating section 2022 to rotate, thereby driving the rotating seat 14 to rotate, and further driving the screw 15 to rotate, so that the movable seat 16 moves along the axis of the screw 15.

[0060] Among them, the guide member 17 is a guide block 171 fixed on the outer wall of the movable seat 16, and a guide groove (not shown in the figure) is provided on the inner wall of the first section 2021 for the guide block 171 to slide in the vertical direction. When the movable seat 16 slides in the first section 2021, it drives the guide block 171 to slide in the guide groove to guide the moving direction of the movable seat 16.

[0061] Reference Figure 2 As shown in Figure 7 , the rotating member 18 includes a collar 181, a mating seat 182, and a rotation source 183. The collar 181 corresponds to each of the flow guide tubes 202. The collar 181 is annular and coaxially fixedly sleeved onto the outer wall of the rotating section 2022 of the corresponding flow guide tube 202. The collar 181 has a plurality of first teeth 19 fixed thereto at even intervals along its circumference. The mating seat 182 is disc-shaped and has a plurality of second teeth 20 fixed thereto at even intervals along its circumference. The mating seat 182 is located within the space enclosed by all of the collars 181. The second teeth 20 on the mating seat 182 simultaneously mesh with the first teeth 19 on all of the collars 181. The rotation source 183 is a motor fixed on the inner top wall of the water collecting tank 201. The motor can rotate forward and reverse. The output section of the motor is coaxially fixed with the center of the mating seat 182 so that the motor can drive the mating seat 182 to rotate. The rotation of the mating seat 182 drives all the rings 181 to rotate synchronously, thereby driving all the rotating sections 2022 to rotate synchronously.

[0062] Reference Figure 7 and Figure 8 Furthermore, in order to improve the watering effect on the vegetation, a nozzle 21 is installed at the top of the first section 2021, which moves up and down. The bottom of the nozzle 21 has a water inlet 22, and multiple water outlet holes 23 are distributed on the nozzle 21. The water outlet holes 23 are also connected to the water inlet 22 of the nozzle 21. When the nozzle 21 moves downward until it contacts the top of the first section 2021, the nozzle 21 is connected to the first section 2021 through the water inlet 22. The water drawn upward by the first section 2021 can enter the water outlet holes 23 from the water inlet 22 and be ejected from the water outlet holes 23 to water the vegetation around the nozzle 21, thereby increasing the range of watering for the vegetation. When it rains, the nozzle 21 is moved upward to separate from the first section 2021, allowing the accumulated rainwater to enter the first section 2021 from the top of the first section 2021.

[0063] Reference Figure 6 and Figure 7 In order to drive the nozzle 21 to change its position, a linkage 24 is provided between the nozzle 21 and the movable seat 16 for driving the nozzle 21 to move. When the movable seat 16 moves to the point where the organ pipe 12 is expanded to cover the through hole 11, the nozzle 21 moves downward against the first section 2021; and when the movable seat 16 moves to the point where the organ pipe 12 is compressed to expose the through hole 11, the nozzle 21 separates upward from the first section 2021.

[0064] Reference Figure 4 and Figure 9 The linkage member 24 includes a mounting box 241, a first rack 242, a gear 243, and a second rack 244. The mounting box 241 is fixed to the inner wall of the first section 2021. The mounting box 241 has an internal hollow structure. The cross-sectional dimensions of the mounting box 241 are smaller than those of the first section 2021, and the top of the mounting box 241 is flush with the top of the first section 2021. The filter screen 27 has a clearance opening for the mounting box 241, allowing water to flow around the mounting box 241 and into the first section 2021.

[0065] Reference Figure 4 and Figure 6 The first rack 242 is fixed to the lower surface of the nozzle 21 and extends in the vertical direction, and the first rack 242 moves and extends into the installation box 241. The second rack 244 is fixed to the upper surface of the movable base 16. The second rack 244 extends in the vertical direction and extends into the installation box 241. The tooth surface of the first rack 242 is opposite to the tooth surface of the first rack 242. Figure 9 The gear 243 is rotatably connected to the mounting box 241 via a rotating shaft, and the first rack 242 and the second rack 244 are respectively engaged with opposite sides of the gear 243.

[0066] When the movable seat 16 moves upward to expand the organ pipe 12, the second rack 244 moves upward, driving the gear 243 to rotate, thereby driving the first rack 242 to move downward synchronously. When the organ pipe 12 completely blocks the through hole 11, the movable seat 16 and the second rack 244 stop moving. At this time, the nozzle 21 is pressed against the upper surface of the first section 2021, so that the water flow drawn upward by the first section 2021 can be sprayed out from the various water outlets 23 of the nozzle 21. Conversely, when the movable seat 16 moves downward to compress the organ pipe 12, the second rack 244 moves downward, driving the first rack 242 to move upward, so that the nozzle 21 is separated from the first section 2021 upward, and rainwater can enter the first section 2021 from the top when it rains.

[0067] The implementation principle of a multi-layer graded purification water circulation system for green spaces according to an embodiment of the present application is as follows: when it rains, the gate is adjusted to connect the main pipe 3 with the water supply pipe 7, and the starting motor drives the ring 181 to rotate through the matching seat 182, so as to drive the rotating section 2022 and the screw 15 to rotate, so that the movable seat 16 drives the organ pipe 12 to move downward and compress, so as to expose the through hole 11 and separate the nozzle 21 from the first section 2021, so that rainwater can flow from the top of the first section 2021 to the water collection chamber 6 for collection, and exchange water flow between the through hole 11 and the pebble layer 103. When it is necessary to water the vegetation, adjust the gate to connect the main pipe 3 with the water pipe 8, start the motor to drive the sleeve 181 to rotate in the opposite direction through the matching seat 182, and start the water pump to send water from the water pipe 8 into the diversion pipe 202, and the organ pipe 12 gradually covers the through hole 11, and the nozzle 21 is offset from the first section 2021, so that water can be ejected from the nozzle 21 to water the vegetation.

[0068] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
