Description

Technical Field

[0001] This invention relates to the field of greening irrigation technology, specifically to a closed-loop reuse system for rainwater purification and recharge in green areas. Background Technology

[0002] In the course of urban development, urban greening has always been a key area that has attracted much attention. Many cities reserve large areas for green spaces and plant a wide variety of plants when carrying out construction plans. In the initial stage of cultivating green vegetation, artificial methods are needed to irrigate and maintain these plants.

[0003] However, the currently widely used irrigation methods mainly involve spraying water using water trucks or sprinkler heads. This irrigation mode has several problems: firstly, it consumes a considerable amount of water, and the water source is relatively limited, which can easily lead to unnecessary waste of water resources; secondly, water trucks and other equipment are bulky, which greatly reduces their convenience in some garden settings.

[0004] Chinese patent CN108179678B discloses a rainwater harvesting and irrigation device for highway greenbelts, comprising: a road surface, roadside drainage bricks, roadside drainage plates, a water storage tank, a micro-irrigation device, micro-irrigation pipes, a micro-irrigation planting box, and drip irrigation pipes; wherein the roadside drainage bricks are laid on the side surface of the road surface, and the roadside drainage plates are installed below the roadside drainage bricks and connected to the side surface of the road surface; the roadside drainage bricks are provided with oblique through holes, and the roadside drainage plates are attached to the roadside drainage bricks and extend to the lower part of the roadbed; the water storage tank is installed below the side of the roadside drainage plates, and the micro-irrigation device includes a front pump chamber, a rear pump chamber, a pad-type one-way valve, an air duct, and a filter; by providing a specific design for a device that collects and stores rainwater and uses wind and solar power to generate electricity for irrigation, the device realizes automatic irrigation of highway greenbelts in remote inland areas without external power, and is especially suitable for promotion and use in areas of Northwest my country with strong winds and long hours of sunshine throughout the year.

[0005] Although the relevant patented technology can achieve rainwater harvesting for irrigation, in actual use, if the solution is deployed under an overpass, the overpass and the trees and vegetation on both sides will block the solar power generation device, resulting in insufficient power generation and making it impossible to carry out normal irrigation operations.

[0006] Meanwhile, existing rainwater recharge systems generally use electromechanical equipment such as water pumps and electric valves combined with electrical controls to purify rainwater and reuse it for irrigation. However, this method of rainwater recharge using electromechanical equipment is complex to operate and maintain, and the failure rate of the electromechanical equipment and electrical control system is high, resulting in high repair and replacement costs, which leads to its low adoption rate.

[0007] Furthermore, current rainwater recharge systems generally use a timed, cyclical irrigation method, which cannot adjust the irrigation according to the actual needs of the vegetation. This results in the vegetation receiving either too much or too little water during rainwater recharge. Summary of the Invention

[0008] The purpose of this invention is to provide a closed-loop reuse system for rainwater purification and recharge in green spaces, aiming to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a closed-loop reuse system for rainwater purification and recharge in green spaces, including a dike, and further comprising: The collection components are arrayed inside the cofferdam, and each component is equipped with a support structure. Rainwater enters the collection components through the support structures. An energy storage and lifting component is disposed inside a collection component. It includes a lifting member located in the middle, a turbine at one end of the lifting member extending out of the collection component, an energy storage member at the other end of the lifting member, and a limiting member at the connection between the lifting member and the collection component. When rainwater flows into the collection assembly through the support components, it impacts the turbine. This impact force causes the lifting components to rotate, so that the energy storage components can store energy. When the ambient temperature exceeds the threshold that the temperature control component on the lifting member can withstand, the temperature control component releases the limiter from restricting the lifting member; at this time, the energy storage component releases energy, and the lifting member reverses. The reversed lifting member collects rainwater from the component and transports it to the vegetation through the recharge component set on top of the collection component to achieve rainwater recharge.

[0010] Preferably, the collection component includes: An outer cylinder has an inner cylinder inside it, and the outer cylinder and the inner cylinder are connected by a connecting hole. The lifting component is located inside the inner cylinder. The collection section, located at the top of the outer and inner cylinders, collects rainwater to impact the turbine. The first through hole and the second through hole are both located at the top of the assembly section. The first through hole is connected to the inner cylinder, and the second through hole is connected to the outer cylinder.

[0011] Preferably, the reinjection assembly includes: The first recharge pipe is arrayed around the inner cylinder, and one end of it that protrudes from the collection assembly is connected to the first water outlet, which is used to recharge the root system of the vegetation. The second irrigation pipe is located on the outside of the inner cylinder. One end of the pipe that passes through the collection assembly is connected to a second water outlet, which is used to spray irrigation onto the leaves of the vegetation.

[0012] Preferably, an adjustment component is provided below the assembly portion, the adjustment component comprising: The movable part, which is arranged in an array below the collection part and is slidably connected to the collection part, blocks the first through hole when it moves axially; The water inlet cylinder is located at the end of the moving part away from the limiting member, and it is slidably connected to the first recharge pipe and the second recharge pipe through elastic parts.

[0013] Preferably, the movable part includes a movable block, which has a clearance part connected to the limiting part and a connecting part adapted to the first through hole. The end of the movable block away from the limiting part is connected to the water inlet cylinder through a mounting plate.

[0014] Preferably, the mounting plate corresponding to the water inlet cylinder connected to the second reinjection pipe has a water guide hole that communicates with the water inlet cylinder.

[0015] Preferably, the limiting member includes a ratchet disposed on the outside of the lifting member, and the ratchet is provided with an array of pawls on its outside.

[0016] Preferably, a protrusion is provided at the engagement point between the pawl and the ratchet, and the protrusion is connected to a clearance portion, which provides space for the pawl to swing.

[0017] Preferably, the lifting component includes a shaft and a spiral body, the shaft is connected to the energy storage component, the shaft is hollow, and the temperature control component is located inside the shaft.

[0018] Preferably, the temperature control component includes: A receiving section is provided at the top of the lifting member, and a receiving body is provided inside the receiving body, wherein a form conversion medium is provided inside the receiving body; The telescopic component is located inside the lifting component, with one end connected to the housing and the other end connected to the magnetic block; When the magnetic block is in the first position, the connecting part and the first through hole are in an overlapping state; when the magnetic block is in the second position, the connecting part and the first through hole are in a misaligned state.

[0019] The technical effects and advantages of this invention are as follows: 1. This invention utilizes the impact force of rainwater flowing into the collection component through the carrier to cause the turbine to rotate, thereby accumulating energy in the energy storage component. When the ambient temperature exceeds the threshold of the temperature control component, the energy storage component releases energy, and the lifting component reverses to transport the rainwater in the collection component to the vegetation for re-irrigation. This eliminates the need for electric irrigation and reduces irrigation costs.

[0020] 2. By setting up a temperature control component, when the surface temperature rises rapidly, the conversion efficiency of the morphology conversion medium inside the container is improved, the elongation of the telescopic component increases, and the repulsive force of the magnetic block on the mounting plate increases. This allows all the water to enter the second recharge pipe and spray out from the spray hole of the second outlet to spray the plant leaves. This avoids the problems that occur when only the roots are irrigated, such as limited water absorption area of ​​the root system, inability to meet the transpiration requirements of the leaves, wilting of leaves, closure of stomata, and obstruction of photosynthesis.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

[0024] Reference Figures 1 to 4 As shown, the present invention provides a closed-loop reuse system for rainwater purification and recharge in green spaces, including a dike 1. Inside the dike 1, there are arrayed collection components 3. Each collection component 3 is provided with a support member 9 on its top. Rainwater enters the collection component 3 through the support member 9.

[0025] The support component 9 includes a frame and an annular permeable net. A permeable component 10 is placed between the frame and the annular permeable net. The permeable component 10 includes permeable bricks. Rainwater is collected into the collection component 3 through the permeable component 10.

[0026] A protective net 11 is installed above the supporting component 9. The protective net 11 supports the soil layer above and prevents it from sinking. The protective net 11 includes a metal wire mesh with a corrosion-resistant soil layer on its surface. Above the protective net 11 is a filter element 12, which includes geotextile fabric for filtering impurities from rainwater. Above the filter element 12 is a gravel layer 13, and above the gravel layer 13 is a planting layer 14 for planting green vegetation.

[0027] The collecting component 3 includes an outer cylinder 301, an inner cylinder 302 inside the outer cylinder 301, and the outer cylinder 301 and the inner cylinder 302 are connected by a connecting hole 303. The inner cylinder 302 is equipped with a lifting component.

[0028] The outer cylinder 301 is higher than the inner cylinder 302. The top of the outer cylinder 301 and the inner cylinder 302 are fixedly connected to a collection part 304. The collection part 304 is fixedly connected to the support member 9. Rainwater is collected in the collection part 304. The collection part 304 is provided with a first through hole 305 and a second through hole 306. The first through hole 305 is connected to the inner cylinder 302. The second through hole 306 is connected to the outer cylinder 301.

[0029] When using it, the following steps should be followed: First, dig out several fixed pits on the fixed soil layer 2 inside the cofferdam 1. Then, place the outer cylinder 301 of multiple collection components 3 into these fixed pits respectively. It is necessary to ensure that the depth of the fixed pits is consistent with the height from the bottom of the bearing component 9 to the outer cylinder 301.

[0030] After the outer cylinder 301 is installed, the permeable component 10 is placed between the frame of the bearing component 9 and the annular permeable net. This provides support for the upper soil layer and also filters rainwater. Next, the protective net 11 is installed on top of the bearing component 9 to support the space above the collection part 304. Then, the filter component 12 is laid on the protective net 11 to achieve rainwater filtration and infiltration. Finally, a gravel layer 13 and a planting layer 14 are laid sequentially on the filter component 12. The gravel layer 13 is used for preliminary rainwater filtration, and the planting layer 14 is used for planting green vegetation.

[0031] When heavy rain or urban flooding occurs, the water flowing into the cofferdam 1 will pass from top to bottom through the planting layer 14, gravel layer 13, filter element 12, and protective net 11, and finally flow into the permeable element 10 on the bearing element 9. During this process, the gravel layer 13 and filter element 12 will filter the rainwater to prevent the water from carrying too many impurities when it enters the outer cylinder 301 and inner cylinder 302 through the collection part 304, which would affect subsequent use.

[0032] Because the carriers 9 on each collecting component 3 are closely arranged, the permeable component 10 can collect all the water flowing into the cofferdam 1 into the outer cylinder 301 and the inner cylinder 302. Specifically, after the water flow is conducted by the permeable component 10, it gathers at the collecting part 304 and flows into the outer cylinder 301 and the inner cylinder 302 through the first through hole 305 and the second through hole 306, respectively. At the same time, since the outer cylinder 301 and the inner cylinder 302 are connected by the connecting hole 303, the water flowing into them is not independent of each other. Example 2

[0033] While the above embodiments can achieve rainwater collection and filtration, in practical applications, existing rainwater recharge systems generally use a timed, periodic irrigation method, which cannot adjust the irrigation according to the actual needs of the vegetation. Furthermore, the irrigation method is generally electric, resulting in high costs. Therefore, based on Embodiment 1, a further improvement is made, and the improved technical solution is shown below: Reference Figures 1 to 10 As shown, the present invention provides a closed-loop reuse system for rainwater purification and recharge in green spaces, including a dike 1. Inside the dike 1, there are arrayed collection components 3, each of which is equipped with a carrier 9. Rainwater enters the collection components 3 through the carrier 9. The collection component 3 is equipped with an energy storage and lifting component 4. The energy storage and lifting component 4 includes a lifting member 401 located in the middle. One end of the lifting member 401 extending out of the collection component 3 is provided with a turbine 404, and the other end of the lifting member 401 is provided with an energy storage member 402. A limiting member 403 is provided at the connection between the lifting member 401 and the collection component 3. When rainwater flows into the collection assembly 3 through the carrier 9, it will impact the turbine 404. This impact force will cause the lifting member 401 to rotate so that the energy storage member 402 can store energy. When the ambient temperature exceeds the threshold that the temperature control component 8 installed on the lifting component 401 can withstand, the temperature control component 8 releases the restriction of the limiting component 403 on the lifting component 401; at this time, the energy storage component 402 releases energy, and the lifting component 401 reverses. The reversed lifting component 401 will collect the rainwater in the component 3 and transport it to the vegetation through the reinjection component 6 installed on the top of the collection component 3 to realize rainwater reinjection.

[0034] Specifically, the collection component 3 includes an outer cylinder 301, an inner cylinder 302 is provided inside the outer cylinder 301, the outer cylinder 301 and the inner cylinder 302 are connected by a connecting hole 303, and the lifting component is located inside the inner cylinder 302. The outer cylinder 301 and the inner cylinder 302 are provided with a collection part 304 at their tops, where rainwater is collected to impact the turbine 404; the collection part 304 is provided with a first through hole 305 and a second through hole 306, the first through hole 305 is connected to the inner cylinder 302; the second through hole 306 is connected to the outer cylinder 301.

[0035] Specifically, the recharge assembly 6 includes a first recharge pipe 601 and a second recharge pipe 603; the first recharge pipes 601 are arrayed around the inner cylinder 302, and one end of the first recharge pipe 601 that extends out of the collection assembly 3 is connected to a first water outlet 602, which is used to recharge the root system of the vegetation; the second recharge pipe 603 is located on the outside of the inner cylinder 302, and one end of the second recharge pipe 603 that extends out of the collection assembly 3 is connected to a second water outlet 604, which is used to spray the leaves of the vegetation.

[0036] The first water outlet 602 is buried in the planting layer 14 or at the junction of the planting layer 14 and the gravel layer 13. The first water outlet 602 is provided with an array of water holes. A filter screen is provided on the outer side of the water holes. Water flows into the first water outlet 602 through the first recharge pipe 601 and then flows out from the water holes on the first water outlet 602, directly recharges the roots of the vegetation.

[0037] The second water outlet 604 is located above the planting layer 14. The second water outlet 604 is provided with an array of spray holes. The diameter of the spray holes is smaller than that of the flow holes. Water flows into the second water outlet 604 through the second recharge pipe 603 and then sprays out from the spray holes on the second water outlet 604. The water flow sprayed from the spray holes recharges the leaves and stems of the vegetation.

[0038] Specifically, an adjustment assembly 7 is provided below the collection section 304. The adjustment assembly 7 includes a moving part 701, which is arrayed below the collection section 304 and slidably connected to it. When the moving part 701 moves axially, it blocks the first through hole 305. A water inlet cylinder 702 is provided at the end of the moving part 701 away from the limiting member 403. The water inlet cylinder 702 is slidably connected to the first reinjection pipe 601 and the second reinjection pipe 603 respectively through the elastic part 703. An array of guide grooves is provided on the outer side of the water inlet cylinder 702 so that water flows through the guide grooves into the first reinjection pipe 601 or the second reinjection pipe 603.

[0039] Specifically, the movable part 701 includes a movable block 7011, which has a clearance part 7012 connected to the limiting part and a connecting part 7013 adapted to the first through hole 305. The end of the movable block 7011 away from the limiting member 403 is connected to the water inlet cylinder 702 through the mounting plate 7014.

[0040] Specifically, the mounting plate 7014 corresponding to the water inlet cylinder 702 connected to the second reinjection pipe 603 is provided with a water guide hole 7015 that communicates with the water inlet cylinder 702.

[0041] Specifically, the limiting member 403 includes a ratchet 4031 disposed on the outside of the lifting member 401, and an array of pawls 4032 distributed on the outside of the ratchet 4031. The pawls 4032 are rotatably connected to the collecting part 304 via a torsion spring. A protrusion 5 is provided at the meshing point between the pawl 4032 and the ratchet 4031, and the protrusion 5 is connected to the clearance part 7012, which provides space for the pawl 4032 to swing.

[0042] Specifically, the lifting component 401 includes a shaft and a spiral body. The shaft is connected to the energy storage component 402. The shaft is hollow, and the temperature control component 8 is located inside the shaft.

[0043] It should be noted that the energy storage component 402 includes a coil spring, and the shaft is connected to the coil spring. The method of forming an energy storage and release mechanism by connecting the coil spring and the shaft is existing technology and will not be described in detail here.

[0044] Specifically, the temperature control component 8 includes a receiving part 801, which is located on top of the lifting member 401 and rotatably connected to the lifting member. The receiving part 801 is fixedly connected to the protective net 11 by wire or other structures, thereby ensuring the fixation of the receiving part 801 when the lifting member 401 rotates. The receiving part 801 contains a container, and the container contains a form conversion medium, including diethyl ether. Diethyl ether is gaseous at temperatures above 34.6°C and liquid at temperatures below 34.6°C. The height of the receiving part 801 can be close to or at the soil surface, so that the temperature control component 8 can be triggered in a timely manner.

[0045] Specifically, the lifting component 401 has an internal telescopic component 802, which includes a spring bellows. One end of the telescopic component 802 is connected to the containment body, and the other end is connected to the magnetic block 803. When the temperature inside the soil layer is above 34.6℃, the ether inside the containment body is converted into a gaseous state. The gaseous ether drives the telescopic component 802 to extend, causing the magnetic block 803 to move towards the energy storage component 402. Since the mounting plate 7014 has a magnetic block that repels the magnetic block 803, when the magnetic block 803 moves towards the energy storage component 402, the magnetic block 803 generates a repulsive force on the mounting plate 7014, thereby driving the mounting plate 7014 to move towards the inner wall of the inner cylinder 302.

[0046] When the magnetic block 803 is in the first position, the connecting part 7013 and the first through hole 305 are in an overlapping state; when the magnetic block 803 is in the second position, the connecting part 7013 and the first through hole 305 are in a misaligned state.

[0047] During use, the magnetic block 803 is initially located in the first position, at which time the connecting part 7013 and the first through hole 305 are in an overlapping state.

[0048] When water flows through the permeable part 10 and is conducted to the collection part 304, it is guided by the inverted conical structure of the collection part 304. The water converges in the collection part 304 and flows into the outer cylinder 301 and the inner cylinder 302 through the first through hole 305 and the second through hole 306 respectively, thus realizing the collection of water.

[0049] It should be noted that in this embodiment, the size of the first through hole 305 is smaller than the size of the second through hole 306, and both the first through hole 305 and the second through hole 306 are provided with filter screens.

[0050] When encountering heavy rain or urban flooding, the water flow converges at the collecting section 304, forming a vortex under the combined action of gravity and inertia. This vortex impacts the turbine 404 located on the collecting section 304, driving the turbine 404 to rotate. When the turbine 404 rotates, it drives the lifting component 401 to rotate in the forward direction, thereby synchronously driving the energy storage component 402 to store energy.

[0051] It should be noted that in this application, an inclined tube can be laid in the soil layer, with one end of the inclined tube extending out of the soil surface to receive the water flow, and the outlet of the other end facing the turbine, so that the water flow directly drives the turbine 404 to rotate, and a filter screen is installed inside the inclined tube.

[0052] It should be noted that the ratchet 4031 is fixedly connected to the shaft of the lifting member 401. When the lifting member 401 rotates in the forward direction, the ratchet 4031 rotates synchronously in the forward direction. At this time, the pawl 4032 slides down the back of the teeth of the ratchet 4031 under the action of the torsion spring, releasing the rotational limit on the ratchet 4031. When the lifting member 401 drives the ratchet 4031 to rotate in the reverse direction, the pawl 4032 engages with the tooth groove of the ratchet 4031 under the action of the torsion spring, thus limiting the rotation of the lifting member 401.

[0053] In this embodiment, the diameter of the turbine 404 is designed to cover the location of the first through hole 305, ensuring that water can enter the inner cylinder 302 through the first through hole 305 when it impacts the turbine 404. When the water stops impacting the turbine 404, the lifting member 401 will not rotate in the opposite direction due to the limiting effect of the ratchet 4031 and the pawl 4032. At this time, the water is temporarily stored inside the inner cylinder 302 and the outer cylinder 301.

[0054] When the surface temperature exceeds the set value, the state-changing medium inside the container changes from liquid to gas, causing an increase in internal pressure within the container and the telescopic component 802. The telescopic component 802 extends, causing the magnetic block 803 to move towards the energy storage component 402, shortening the straight-line distance between the mounting block and the magnetic block 803. Because of the magnetic repulsion between the magnetic block on the mounting plate 7014 and the magnetic block 803, the moving magnetic block 803 generates a repulsive force on the mounting plate 7014, pushing it towards the inner wall of the inner cylinder 302.

[0055] When the mounting plate 7014 moves towards the inner wall of the inner cylinder 302, it simultaneously drives the movable block 7011 and the water inlet cylinder 702 to move. During the movement of the movable block 7011, on the one hand, the relief part 7012 pulls the protrusion 5 on the pawl 4032, so that the pawl 4032 releases its restriction on the ratchet 4031; on the other hand, it causes the connecting part 7013 to intersect with the first through hole 305. When the magnetic block 803 moves to the second position, the connecting part 7013 on the movable block 7011 and the first through hole 305 are in a misaligned state, that is, the movable block 7011 blocks the first through hole 305; at the same time, the relief part 7012 on the movable block 7011 drives the pawl 4032 to release its restriction on the ratchet 4031.

[0056] It should be noted that when the ratchet 4031 and the pawl 4032 are engaged, the protrusion 5 on the pawl 4032 contacts the side of the relief part 7012 near the lifting member 401. The size of the relief part 7012 is sufficient to allow the movement of the protrusion 5 when the pawl 4032 deflects.

[0057] After the pawl 4032 releases its restraint on the ratchet 4031, the energy storage component 402 releases energy to drive the lifting component 401 to reverse. When the lifting component 401 rotates in the reverse direction, its spiral body is located inside the inner cylinder 302, lifting the water in the inner cylinder 302 to the top. Since the first through hole 305 is blocked at this time, the water cannot enter the collection part 304, but flows into the first recharge pipe 601 and the second recharge pipe 603 through the water inlet pipe 702. The water flowing into the first recharge pipe 601 merges with the first outlet 602 and flows out through the water outlet on the first outlet 602, directly recharges the plant roots.

[0058] When the surface temperature rises rapidly, the conversion efficiency of the morphology conversion medium inside the container increases simultaneously, resulting in an increase in the elongation of the telescopic component 802 per unit time, which in turn increases the repulsive force of the magnetic block 803 on the magnetic block on the mounting plate 7014.

[0059] When the magnetic block 803 moves to the third position, the connecting part 7013 on the movable block 7011 and the first through hole 305 are still misaligned, and the pawl 4032 releases the restriction on the ratchet 4031; at the same time, the mounting plate 7014 is attached to the inner wall of the inner cylinder 302, and the water inlet cylinder 702 is completely inserted into the first recharge pipe 601 and the second recharge pipe 603. The mounting plate 7014 will block the first recharge pipe 601, but since the mounting plate 7014 corresponding to the water inlet cylinder 702 connected to the second recharge pipe 603 has a water guide hole 7015, after the mounting plate 7014 is attached to the inner wall of the inner cylinder 302, the water guide hole 7015 is connected to the second recharge pipe 603, and the water can enter the second recharge pipe 603 through the water guide hole 7015.

[0060] After the pawl 4032 releases its restraint on the ratchet 4031, the energy storage component 402 releases energy again, causing the lifting component 401 to reverse. When the lifting component 401 rotates in the reverse direction, its spiral body lifts the water in the inner cylinder 302 to the top. Since the first through hole 305 and the first recharge pipe 601 are both blocked at this time, all the water lifted by the lifting component 401 enters the second recharge pipe 603. Due to the large volume of water, the water entering the second recharge pipe 603 is sprayed out from the spray hole of the second outlet 604, directly spraying the plant leaves. This avoids the problems of limited root water absorption area, inability to meet leaf transpiration requirements, leaf wilting, stomatal closure, and hindered photosynthesis that occur when only the roots are irrigated.

[0061] It should be noted that when the magnetic block 803 is in the second position, water enters both the first recharge pipe 601 and the second recharge pipe 603, resulting in a smaller flow rate into the second recharge pipe 603. At this time, the water entering the second outlet 604 can only flow out through the water outlet to irrigate the surface of the planting layer 14, without spraying the plant leaves.

[0062] It should be noted that in this embodiment, after the rainwater enters the collection component 3, since the outer cylinder 301 and the inner cylinder 302 are connected through the connecting hole 303, and the outer cylinder 301 is connected to the collection part 304 through the second through hole 306, when the rainwater is stored in the collection component 3, due to the evaporation of the rainwater, the water vapor can directly enter the area above the protective net 11 through the first through hole 305 and the second through hole 306 to moisten the bottom area of ​​the vegetation. Alternatively, a self-priming pipe or similar component can be installed at the second through hole 306 so that after the rainwater is stored in the collection component 3, it can directly moisten the bottom area of ​​the vegetation in the subsequent time.

[0063] In this way, the rainwater stored inside the collection component 3 can continuously moisturize the vegetation. However, since its self-evaporation cannot meet the actual needs of the plants under high temperature conditions, when the surface temperature exceeds the set value, the pawl 4032 releases the limit on the ratchet 4031, and the energy storage component 402 releases energy to drive the lifting component 401 to reverse, pumping the rainwater upwards for recharge. The pumped rainwater is the residual rainwater that is evaporating or has already evaporated more than half of its original volume inside the collection component 3. At the same time, even if the reverse rotation of the lifting component 401 cannot pump all the residual rainwater, the remaining rainwater can still moisturize the bottom area of ​​the vegetation on its own through the evaporation of the rainwater.

[0064] This invention utilizes the accumulated gravitational potential energy and kinetic energy generated when rainwater flows in through the arrayed collection components 3 to impact the turbine 404, converting discrete rainfall energy into mechanical energy and storing it in the energy storage component 402. Due to the asymmetric design of "large-area energy collection and small-scale work" adopted by the system, the energy stored in the energy storage component 402 is sufficient to overcome mechanical losses and lift some of the high-value water resources inside the inner cylinder 302 to the surface during extreme high-temperature periods. This avoids the limitation of instantaneous energy conservation and achieves active reinjection during critical dry seasons through long-term energy accumulation, significantly reducing maintenance costs.

[0065] During the system's operation cycle, water utilization is divided into two logical phases. The first phase is normal passive humidification. After rainwater is stored in the collection component 3, during non-high-temperature periods, it continuously and in small amounts provides a humid environment to the bottom area of ​​the vegetation through the natural evaporation of water vapor and the self-suction pipe set at the second through hole 306. At this time, the energy storage component 402 is in a static energy storage state. The second phase is active reinjection during extreme high temperatures: when the surface temperature rises to the threshold where natural humidification cannot offset the transpiration loss of the vegetation, the temperature control component 8 senses the environmental change and releases the limit, releasing the mechanical energy accumulated in the previous stage; at this time, the lifting component 401 reverses, forcibly pumping deep, clear water to the roots or leaves, achieving closed-loop precise replenishment for high-temperature drought.
