DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in conjunction with specific embodiments.

[0046] Example one: as​​​​Figures 1 to 8 As shown, the modular integrated rainwater collection, sprinkling cooling and intelligent irrigation system according to the embodiments of the present application comprises:

[0047] A modular water storage unit 1 is arranged in a foundation pit for collecting and storing rainwater, the side wall of the water storage unit 1 is a porous structure, and a plurality of water storage units 1 are connected to each other through the butt joint holes 10 of the side walls to form an underground water storage device;

[0048] A permeable pavement layer is arranged above the water storage unit 1 for guiding the surface rainwater to the water storage unit 1;

[0049] An irrigation and cooling execution device comprises a water pump 4, a water supply main pipe 5 and a water supply branch pipe 6, the water inlet end of the water pump 4 is connected to the underground water storage device, and the water outlet end is connected to the water supply main pipe 5; the water supply branch pipe 6 is divided into a sprinkling branch pipe and an irrigation branch pipe; the sprinkling branch pipe is provided with a spray head 11 for environmental mist cooling, and the irrigation branch pipe is provided with an irrigation pipeline for plant irrigation; the water supply main pipe 5 is provided with an electromagnetic valve for controlling the on-off of the water supply branch pipe 6;

[0050] An intelligent control assembly comprises a central controller, a weather monitoring station 3 for collecting environmental meteorological data and a soil moisture sensor for monitoring soil moisture; the central controller is signal connected to the weather monitoring station 3, the soil moisture sensor and the water pump 4.

[0051] It also comprises a filling layer 7 and a covering layer 8, the filling layer 7 is filled around the water storage unit 1, and the covering layer 8 covers the top of the water storage unit 1 and the filling layer 7.

[0052] Among them, the spray head 11 adopts a micro atomizing spray head 11 and is embedded in a ground pavement gap (such as a brick joint of a water permeable brick 2) or a curbstone side surface; the weather monitoring station 3 is internally provided with relevant monitoring sensors for collecting environmental temperature, humidity and weather forecast information; the water storage unit 1 is also provided with a liquid level sensor for monitoring the water level in the inner cavity of the water storage unit 1.

[0053] In operation, the surface rainwater is first filtered and guided through the permeable pavement layer to collect the rainwater into the modular water storage unit 1 below. The water storage unit 1 is designed with a porous structure, which has the functions of filtering and increasing the specific surface area. A plurality of water storage units 1 are connected to form a honeycomb structure underground water storage device, which is stable and efficient, can fully utilize the underground space to store a large amount of rainwater, and is connected through the butt joint holes 10 of the side walls, so that the rainwater stored in the plurality of water storage units 1 can flow to each other, and the principle of communicating vessels is used to ensure the balance of the overall water level of the underground water storage device and prevent local waterlogging or low water level.

[0054] The cover layer 8 and the filling layer 7 can be made of different volumes of sand and gravel. By reasonable proportioning, the stability of the water storage unit 1 can be ensured, and rainwater can also pass through to facilitate the collection of rainwater into the water storage unit.

[0055] When the ambient temperature rises or the soil humidity is insufficient, the intelligent control component begins to work. The meteorological monitoring station 3 collects real-time environmental meteorological data, including temperature, humidity, wind speed, etc.; the soil humidity sensor monitors the soil humidity. These data are transmitted to the central controller for analysis and processing.

[0056] The central controller makes intelligent decisions according to the preset priority rules. If the soil humidity is lower than the preset drought threshold, and the underground water storage device water level is higher than the low water level threshold, the irrigation mode is started, and the rainwater in the water storage unit 1 is pumped out by the water pump 4, and is delivered to each irrigation area through the irrigation branch pipe, to ensure the survival of plants. If the soil humidity meets the standard, but the ambient temperature is higher than the high temperature trigger threshold, and the weather forecast is sunny or no rain, the spray cooling mode is started, and the rainwater is delivered to the spray head 11 through the spray branch pipe, and then the rainwater is atomized and sprayed into the air to reduce the ambient temperature. Through the intelligent decision model, the limited rainwater resources are dynamically optimized and allocated between the "cooling" and "irrigation" functions, avoiding conflicts with control logic and resource waste, achieving "one water multiple use", and significantly improving the comprehensive utilization efficiency of water resources and the energy (energy for pumping) it carries.

[0057] In addition, the collected rainwater is used for surface spraying cooling, and the evaporation and heat absorption process indirectly reduces the water temperature of the underground water storage device, creating favorable conditions for inhibiting the growth of algae in the water storage in hot seasons, improving water quality stability; and the cooling operation through the microporous spray, part of the water vapor penetrates to the plant roots under the action of gravity, realizing "incidental" deep irrigation during the cooling process, reducing surface evaporation loss compared with traditional surface flooding.

[0058] Preferably, the water storage unit 1 is a regular hexagonal prism, each side of the water storage unit 1 is provided with a butt joint hole 10, and a plurality of water storage units 1 are combined to form a honeycomb structure of the underground water storage device through the side wall.

[0059] When working, a plurality of regular hexagonal prism-shaped water storage units 1 are spliced with each other through the butt joint holes 10 of the side walls. Due to the characteristics of the regular hexagon, the spliced underground water storage device forms a stable honeycomb structure. This structure not only has high structural strength and can withstand certain external pressure, but also has high space utilization rate and can store more rainwater.

[0060] Preferably, a sealing assembly is arranged at each of the abutment holes 10; the sealing assembly comprises a sealing block 14 matched with the abutment hole 10, and a reciprocating driving mechanism arranged in the inner cavity of the water storage unit 1 and used to drive the sealing block 14 to seal or unseal.

[0061] The reciprocating driving mechanism comprises a magnetic block 15 and an elastic reset assembly.

[0062] The magnetic block 15 is fixedly arranged on the side of the sealing block 14 opposite to the inner cavity of the water storage unit 1.

[0063] The elastic reset assembly comprises at least one pair of guide rods 21 fixedly arranged on the inner side of the abutment hole 10, a sleeve 20 is sleeved on each guide rod 21, the sleeve 20 is fixedly connected with the sealing block 14 through a connecting block 19, and a spring 22 is sleeved on the guide rod 21 to reset the sleeve 20.

[0064] In operation, when two water storage units 1 are connected, the abutment holes 10 on the side walls are aligned with each other. At this time, the magnetic blocks 15 on the sealing blocks 14 in the two opposite abutment holes 10 have the same magnetic property on the opposite surfaces, repulsion is generated, and the two opposite sealing blocks 14 are driven to move towards the inner cavities of the water storage units 1 respectively, so that the adjacent abutment holes 10 are conducted, and the rainwater in the two water storage units 1 can flow to each other.

[0065] During the movement of the sealing block 14 towards the inner cavity of the water storage unit 1, the sealing block 14 drives the sleeve 20 to slide on the guide rod 21 through the connecting block 19, and the spring 22 is compressed. The guide rod 21 and the sleeve 20 cooperate to ensure the stability of the movement of the sealing block 14 and prevent the sealing block 14 from deviating or jamming. When the two water storage units 1 are separated, the repulsion between the magnetic blocks 15 disappears, the reset force of the compressed spring 22 drives the sleeve 20 to slide reversely on the guide rod 21, and then drives the sealing block 14 to move towards the abutment hole 10 through the connecting block 19 until the sealing block 14 seals the abutment hole 10 again to prevent the rainwater in the water storage unit 1 from leaking. Similarly, the abutment holes 10 on the side wall of the water storage unit 1 which are not adjacent to other adjacent units are also automatically sealed.

[0066] Preferably, an annular elastic member 18 is fixedly connected to the outer wall of the sealing block 14, an elastic block 16 is fixedly connected to the end of the sealing block 14 towards the inner side of the water outlet unit, the elastic block 16 and the elastic member 18 are designed as a hollow structure, and the elastic block 16 stores gas in the inside; the elastic block 16 and the elastic member 18 are connected with each other through a communication pipe 23.

[0067] When the blocking block 14 is pushed into the docking hole 10, the elastic member 18 is in elastic contact with the inner wall of the docking hole 10, thereby achieving a good sealing effect and preventing rainwater from leaking from the gap between the docking hole 10 and the blocking block 14. Meanwhile, since the elastic block 16 is a hollow structure and stores gas inside, when the amount of rainwater in the water storage unit 1 gradually increases, the pressure on the elastic block 16 increases, causing the elastic block 16 to deform and press the air inside the elastic block 16 into the elastic member 18 through the communication pipe 23, so that the elastic member 18 further expands and enhances the sealing effect with the inner wall of the docking hole 10, thereby ensuring the sealing of the water storage unit 1.

[0068] Preferably, a section of the inner wall of the docking hole 10 close to the outside is provided with internal threads, and a connecting head 9 is threadedly connected in the docking hole 10, and the connecting head 9 is connected to an external device.

[0069] When it is necessary to connect the water storage unit 1 to an external device (such as a water pump 4), the connecting head 9 with external threads is simply screwed into the internal threads of the docking hole 10, and the connecting head 9 is connected to the water inlet end of the water pump 4 through a pipeline, thereby achieving stable connection. This threaded connection method is not only convenient to install and disassemble, but also can ensure the sealing of the connection to prevent rainwater leakage. Meanwhile, the design of the connecting head 9 also enables the water storage unit 1 to be matched with various external devices of different specifications and types, thereby improving the versatility and flexibility of the system. After the connection is completed, the external device can extract rainwater from the water storage unit 1 through the connecting head 9 for irrigation or spraying cooling work.

[0070] Preferably, the side of the blocking block 14 opposite to the inner cavity of the water outlet unit is fixed with a top rod 17.

[0071] When the connecting head 9 is screwed into the docking hole 10, the connecting head 9 will touch the end of the top rod 17, thereby pushing the blocking block 14 to move towards the inner cavity of the water storage unit 1, so that the docking hole 10 is open to achieve the opening of the connecting head 9 to the water storage unit 1.

[0072] Embodiment Two: as shown in Figure 5 the comparison embodiment one, another embodiment of the present application is that: each side of the water storage unit 1 is provided with a limiting strip 12 and a limiting groove 13, and the limiting strip 12 and the limiting groove 13 are matched.

[0073] In operation, the limiting strips 12 and the limiting grooves 13 are arranged along the height direction of the water storage unit 1. When multiple water storage units 1 are spliced, the limiting strips 12 on one side of a water storage unit 1 are aligned with the limiting grooves 13 on the side of an adjacent water storage unit 1, and then the limiting strips 12 are inserted into the limiting grooves 13 along the height direction. Due to the matching design of the limiting strips 12 and the limiting grooves 13, they can be tightly fitted to play a positioning and fixing role. In this way, during splicing, the relative positions of the water storage units 1 can be ensured to be accurate, avoiding misalignment during splicing, making the structure of the spliced underground water storage device more stable, better able to withstand external pressure, and ensuring the integrity and stability of the honeycomb structure formed by splicing multiple water storage units 1, which is conducive to the storage and circulation of rainwater. At the same time, this limiting design also facilitates the installation and disassembly of the water storage unit 1, improving the construction efficiency.

[0074] As shown in Figure 9 the modular integrated rainwater collection, sprinkling cooling and intelligent irrigation method, the method uses the above-mentioned modular integrated rainwater collection, sprinkling cooling and intelligent irrigation system, and includes the following steps:

[0075] S1, data acquisition and state judgment: real-time acquisition of soil moisture S, environmental temperature T, weather forecast data (such as whether it will rain in the next 1-2 hours) and underground water storage device water level L;

[0076] S2, intelligent decision-making: the central controller makes decisions based on the following priority rules:

[0077] ① Rule one (irrigation priority): if S < S_min (preset drought threshold) and L > L_low (low water level threshold), start the irrigation mode to ensure plant survival;

[0078] ② Rule two (cooling decision): if S ≥ S_min and T > T_high (high temperature trigger threshold) and the weather forecast is sunny or no rain, start the sprinkling cooling mode;

[0079] ③ Rule three (coordination and prediction): if T > T_high and S < S_min, but the weather forecast is about to rain, the controller can reduce the amount of irrigation water, use more water resources for immediate cooling, and wait for rainwater to supplement irrigation;

[0080] ④ Rule four (resource protection): if L < L_low, stop all unnecessary water use and only retain basic ecological functions;

[0081] S3, execution and feedback: according to the decision result, the controller starts the corresponding water pump 4 and electromagnetic valve, controls the micro-porous spray device or irrigation system to work, and monitors the water level and environmental parameter changes in real time, dynamically adjusts the strategy.
