Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and in particular to a smart agricultural energy storage irrigation drainage and water-saving drip irrigation system. Background Technology

[0002] With the advancement of agricultural modernization, traditional agricultural irrigation and drainage systems are no longer adequate for the demands of large-scale, precision agricultural production. Currently, the industry faces numerous technical challenges that severely hinder the improvement of agricultural production efficiency and green, sustainable development. On the one hand, irrigation water supply relies excessively on artificial replenishment or solely on groundwater extraction, resulting in extremely low utilization of natural rainfall. This not only increases labor and water resource costs but also easily leads to ecological problems caused by excessive groundwater extraction. Existing rainwater harvesting equipment lacks efficient collection, transportation, and storage mechanisms, and its supporting docking and replenishment facilities are inadequate, further reducing the efficiency of rainwater resource utilization. On the other hand, water conveyance systems often suffer from irrational layouts and insufficient utilization of natural terrain. They either require extensive excavation of surface ditches, occupying farmland resources, or consume excessive energy during water conveyance. Furthermore, the lack of precise control measures at each level of water conveyance nodes easily leads to water waste. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides a smart agricultural energy storage irrigation and drainage water-saving drip irrigation system, comprising: The Tianbushui module uses a cluster of drones to collect rainwater from areas near farmland and transport it to an aqueduct for storage, achieving efficient collection and storage of water resources. The ground water conveyance module connects the four-level canal system (main canal, branch canal, distribution canal, and farm canal) with the aqueduct to achieve precise transportation of stored water resources, delivering rainwater and supplementary water from the aqueduct to the fields. The irrigation module uses drip irrigation tapes connected to irrigation canals along the distribution of crops in the field to irrigate the crops and ensure a balanced supply of water for crop growth. The energy storage and power generation module utilizes the gravity potential energy of the water stored in the aqueduct to generate electricity, which complements photovoltaic power generation, thus enabling the system to replenish its own energy.

[0010] Preferably, the fixing grooves are symmetrically arranged, the drip irrigation tape is placed in the fixing grooves, and the bottom end of the fixing groove is provided with a fixing rod for insertion into the farmland soil. The fixing rod is conical. The fixing grooves are connected by a multi-stage telescopic rod. The edge of the fixing groove away from the multi-stage telescopic rod is hinged with a groove cap. The end of the groove cap away from the hinge is provided with a protrusion. The edge of the fixing groove near the multi-stage telescopic rod is provided with a groove. An elastic buckle is provided in the groove. The protrusion is secured in the groove by the elastic buckle.

[0011] Preferably, the energy storage power generation module includes a hydroelectric generator, and a mounting base for installing the hydroelectric generator is provided on the support pier.

[0012] Preferably, the side of the mounting base extends outward and is equipped with a solar photovoltaic panel to generate electricity using solar energy, forming a complementary power generation system with the hydroelectric generator.

[0013] Preferably, water level sensors are installed inside the aqueduct, main canal, branch canal, distribution canal, well, and drainage pond.

[0014] The advantages and positive effects of the smart agricultural energy storage irrigation and drainage water-saving drip irrigation system described in this invention are as follows: 1. Addressing the pain points of traditional agriculture's over-reliance on groundwater extraction and low utilization rate of natural rainwater, this project utilizes drone swarms to precisely collect rainfall data around farmland, combined with segmented aqueducts for efficient rainwater storage, and drone landing bases to improve resupply support. This maximizes the value of natural water resources, significantly reduces artificial water replenishment and groundwater extraction, thereby lowering water and labor costs for agricultural production and effectively avoiding ecological problems caused by excessive groundwater extraction, thus achieving green and sustainable utilization of water resources. 2. Addressing the pain points of traditional water conveyance systems, such as unreasonable layout, large land occupation, high energy consumption, and extensive regulation, the four-level canal system is strictly laid out according to the natural terrain, without the need to forcibly modify the terrain. It relies on the terrain difference to achieve gravity water conveyance, and is equipped with water pumps to assist water conveyance, which significantly reduces water conveyance energy consumption. At the same time, by precisely regulating the water conveyance nodes at each level, it solves the problems of uneven water conveyance and serious waste, and improves water conveyance efficiency and water resource utilization.

[0015] 3. The system adopts a double-sided symmetrical drip irrigation tape layout, combined with a unit fixing frame that can adapt to different crop row spacings, to ensure that the drip irrigation tape is in a stable position and that the water output is uniform, so as to achieve balanced water supply on both sides of the crop and avoid water shortage or water accumulation on one side; combined with real-time monitoring of soil moisture sensors, irrigation can be started as needed, reducing water evaporation and leakage, greatly improving water resource utilization, while ensuring a balanced supply of water required for crop growth, thereby improving crop yield and quality. 4. The four-level canal system enables rapid collection of waterlogging in the fields. Combined with the coordinated operation of drainage ponds, drainage pumps and solenoid valves, it enables automatic monitoring and discharge of waterlogging, quickly draining waterlogging from the fields, avoiding prolonged soaking of waterlogging that can cause crop root rot, reducing flood losses in agricultural production, and improving the disaster resistance of farmland. 5. Hydropower and photovoltaic power generation form a complementary model, making full use of the potential energy of rainwater from the aqueduct and solar energy to achieve energy self-sufficiency of the system, significantly reducing dependence on the external power grid, reducing electricity expenses, and lowering system operating costs; at the same time, it practices green and environmentally friendly concepts, reduces carbon emissions, and is in line with the trend of green agricultural development. 6. The unit fixing frame can adjust the spacing through multi-level telescopic rods to adapt to the planting row spacing of different crops; the segmented aqueduct can flexibly adjust the length, and the four-level canal system can be flexibly deployed according to the irrigation area, adapting to different application scenarios such as large-scale farmland and modern agricultural parks. With the help of the intelligent management and control platform, it is easy to popularize and apply in various agricultural production scenarios, further promoting the green and efficient development of agriculture.

In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] Example: Figures 1-8 The diagram shown is only a conceptual layout of the system; the actual layout will be redesigned based on local conditions.

[0023] The present invention discloses a smart agricultural energy storage irrigation and drainage water-saving drip irrigation system, which includes a sky water supply module, a ground water conveyance module, a canal irrigation module, an energy storage power generation module, and a smart management and control platform.

[0024] The natural water replenishment module uses a cluster of 3 drones to collect rainwater from the nearby rainfall areas and transport it to the aqueduct 1 for storage. This enables efficient collection and storage of water resources, solves the problem of irrigation water supply for farmland, and reduces the cost of artificial water replenishment by relying on natural rainfall.

[0025] The ground water conveyance module connects to the aqueduct 1 via a four-level canal system consisting of main canal 8, branch canal 9, distribution canal 10, and farm canal 11, enabling precise transportation of stored water resources. This allows rainwater and supplementary water from the aqueduct 1 to be delivered to the fields to meet crop irrigation needs.

[0026] The irrigation module, through the placement of drip irrigation tapes 12 along the distribution of crops in the farmland and connected to the irrigation canals 11, achieves precise irrigation of crops, reduces water waste, and ensures a balanced supply of water needed for crop growth.

[0027] The energy storage and power generation module utilizes the gravity potential energy of the water stored in the aqueduct 1 to generate electricity, complementing photovoltaic power generation, thereby achieving the system's own energy replenishment, reducing energy consumption costs during system operation, and improving energy utilization efficiency.

[0028] The intelligent management and control platform enables intelligent monitoring, scheduling, and control of the entire process of the rainwater replenishment module, ground water conveyance module, canal irrigation module, and energy storage power generation module.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the rainwater replenishment module includes an aqueduct 1 for storing rainwater. The aqueduct 1 is constructed along the natural terrain, eliminating the need for drastic topographical alteration and minimizing damage to the ecological environment. It also utilizes the terrain difference to achieve natural water flow, reducing energy consumption for water transport. The aqueduct 1 is segmented, with several segments connected sequentially. Support piers 2 are constructed downwards at the connection points of adjacent segments. These support piers 2 support the aqueduct 1 in the air, preventing it from occupying farmland and protecting it from erosion by debris and accumulated water, ensuring structural stability and extending its service life. The bottom of the segmented aqueduct 1 is designed with a downward-convex arc shape to facilitate subsequent gravity-driven water transport. Both the aqueduct 1 and the support piers 2 are constructed of reinforced concrete, ensuring their strength, corrosion resistance, and impact resistance, adapting to complex open-air field environments and extending the overall service life of the system.

[0030] On both sides of the aqueduct 1 are drone landing bases 4, facilitating convenient docking, resupply, and maintenance for the drone swarm, shortening resupply time after rain collection and improving rain collection efficiency. The drone landing base 4 is a closed enclosure with openings at both ends. The drones fly out from these openings, allowing for ventilation and preventing moisture damage and aging during long-term storage. The closed enclosure effectively protects the drones from wind, rain, sun, and damage from field debris. Each drone landing base 4 contains several drones and wireless charging units for charging. The wireless charging units enable fast and convenient charging of the drones, eliminating the need for manual plugging and unplugging of the charging interface, improving resupply efficiency, reducing wear on the charging interface, and extending the drones' lifespan.

[0031] like Figure 4 As shown, the drone 3 is equipped with a steel frame 5 that covers its central fuselage and is fixedly connected to the drone 3 fuselage. A funnel-shaped rain collection trough 6 is located at the top of the steel frame 5 (the drone 3 can be a modified DJI rotor drone 3; the height of its sampling trough has been experimentally tested and will not affect the rotor rotation that drives the drone 3's flight). The bottom of the steel frame 5 is flush with the lowest point of the drone 3 fuselage, without affecting the drone 3's wireless charging. A drainage pipe 7 is attached to the steel frame 5. The top of the drainage pipe 7 is connected to the rain collection trough 6, and the bottom of the drainage pipe 7 is located at the bottom of the steel frame 5. A solenoid valve is installed on the drainage pipe 7. After the rainwater collected by the rain collection trough 6, the drone 3 flies over the aqueduct 1, the solenoid valve opens, and the drainage pipe 7 quickly and smoothly drains the rainwater into the aqueduct 1. The function of the steel frame 5 is to fix the rain collection trough 6 and the drainage pipe 7, and at the same time, to protect the central fuselage of the drone 3, preventing rainwater and debris from directly impacting the core components of the fuselage during rain collection. The funnel-shaped structure increases the rainwater collection area, improves rainwater collection efficiency, facilitates rapid rainwater accumulation, prevents rainwater splashing and loss, and does not affect the flight of the (rotor-wing) UAV 3.

[0032] The ground-level water conveyance module includes main canals 8, branch canals 9, distribution canals 10, and farm canals 11, all excavated according to the natural terrain. The purpose of excavating according to the natural terrain is to utilize the terrain difference to achieve natural water flow, reducing the frequency of water pump use, lowering energy consumption, and minimizing damage to the original topography, thus protecting the ecological environment. At the lowest point of the aqueduct 1, a gravity conveying pipe 22 connects to the water pump located on the ground. Utilizing the terrain difference between the aqueduct 1 and the ground, initial gravity conveying of rainwater is achieved, reducing the workload of the water pump. The water pump provides power support when the terrain difference is insufficient or rapid water conveyance is required, ensuring that water resources can be quickly and accurately delivered to each level of the canal system. The water pump is connected to several main canals 8 via water conveyance pipes. Each main canal 8 is connected to several branch canals 9, each branch canal 9 is connected to several distribution canals 10, and each distribution canal 10 is connected to several farm canals 11. Main canal 8, branch canal 9, distribution canal 10, and farm canal 11 are connected in pairs, with water pumps and pipelines installed to assist water delivery based on the actual terrain. Solenoid valves are also installed to control water flow. Main canal 8, branch canal 9, distribution canal 10, and farm canal 11 form a four-tiered canal system, enabling stratified and zoned water resource delivery. This ensures precise allocation of water resources to each plot of farmland, preventing waste and facilitating differentiated water delivery management based on the water requirements of different crops in different areas. Main canal 8, branch canal 9, distribution canal 10, and farm canal 11 are connected to drainage ponds via drainage pipes and pumps at the lowest points of the natural terrain.

[0033] The ground-level water conveyance module also includes wells, which are connected to the main canal 8 and aqueduct 1 via water pumps and pipelines to replenish water resources for the four-level canal system and aqueduct 1. During dry seasons or when insufficient rainfall leads to insufficient water storage in aqueduct 1, the wells provide supplementary water to the system, ensuring the continuity of irrigation and preventing crops from being affected by water shortage. At the same time, when the water quality in aqueduct 1 is poor, the wells can be used to replenish water to improve irrigation water quality and enhance crop growth quality.

[0034] like Figure 5 , Figure 6 , Figure 7 As shown, the irrigation module includes symmetrical drip irrigation tapes 12 arranged according to the distribution of crops in the field. The drip irrigation tapes 12 are connected to the irrigation canal 11 via a water pump. The drip irrigation tapes 12 are symmetrically arranged on both sides of each row of crops, so that both sides of the crops can receive water evenly, avoiding water shortage or water accumulation on one side of the crops, ensuring balanced crop growth, improving water resource utilization, and reducing water evaporation and waste. Several unit fixing frames 13 are provided on the drip irrigation tapes 12 to fix the drip irrigation tapes 12 and maintain their position in the field, preventing the drip irrigation tapes 12 from shifting, tangling, or being damaged due to wind, rain, field operations, etc., ensuring accurate drip irrigation position and stable irrigation effect.

[0035] The unit fixing frame 13 is made entirely of plastic. Plastic is lightweight, inexpensive, corrosion-resistant, and age-resistant, making it suitable for damp, impurity-rich field environments, while also facilitating manufacturing and installation. The unit fixing frame 13 uses several units, providing ample space for drip irrigation while securing the drip tape 12. The unit fixing frame 13 includes symmetrically arranged fixing slots 14, within which the drip tape 12 is placed. The bottom of each slot has a fixing rod 15 for insertion into the soil. The fixing rod 15 is tapered, facilitating quick insertion and providing strong stability to effectively secure the unit fixing frame 13 and prevent movement. The units are connected by multi-stage telescopic rods 16, allowing for flexible adjustment of the distance between two fixing slots 14 according to crop row spacing, adapting to different crop planting needs and enhancing the versatility of the unit fixing frame 13. A groove cap 17 is hinged to the edge of the fixing groove 14 away from the multi-stage telescopic rod 16. A protrusion 18 is provided at the end of the groove cap 17 away from the hinge. A groove 19 is provided on the edge of the fixing groove 14 near the multi-stage telescopic rod 16. An elastic buckle is provided in the groove 19, and the protrusion 18 is secured in the groove 19 by the elastic buckle. The groove cap 17 presses and fixes the drip irrigation tape 12 in the fixing groove 14 to prevent the drip irrigation tape 12 from sliding in the fixing groove 14. At the same time, the design of the elastic buckle facilitates the opening and closing of the groove cap 17, making it convenient to install on the drip irrigation tape 12.

[0036] like Figure 8 As shown, the energy storage and power generation module includes a hydroelectric generator 20. A mounting base 21 for installing the hydroelectric generator 20 is provided on the support pier 2. The hydroelectric generator 20 generates electricity using the potential energy of water falling sequentially by gravity in the gravity conveying pipe 22. This converts the gravitational potential energy of the water resources in the aqueduct 1 into electrical energy, achieving energy recycling and providing power support for equipment such as the drone 3 and water pumps within the system. This reduces the system's dependence on the external power grid and lowers operating costs.

[0037] Solar photovoltaic panels 23 are installed on the side of the mounting base 21, extending outward to generate electricity using solar energy, thus complementing the hydroelectric generator 20. In sunny weather without rainfall and when the water flow potential energy of the aqueduct 1 is insufficient, this provides a stable power supply to the system, improving the power supply stability and continuity of the energy storage and power generation module, further reducing energy consumption costs, and achieving comprehensive utilization of clean and environmentally friendly energy.

[0038] Water level sensors are installed inside aqueduct 1, main canal 8, branch canal 9, distribution canal 10, wells, and drainage ponds. Flow sensors are installed on gravity conveying pipeline 22, on the water conveying pipeline connecting main canal 8 and the water pump, at the connection between main canal 8 and branch canal 9, branch canal 9 and distribution canal 10, distribution canal 10 and irrigation canal 11, irrigation canal 11 and drip irrigation tape 12, on the water conveying pipeline connecting wells and the water pump, and on drainage pipelines. Several soil moisture sensors are installed at crop planting areas in farmland. Solenoid valves are installed on various water conveying and drainage pipelines according to actual conditions. The intelligent management and control platform obtains meteorological information through the network to control the take-off and return of drones 3 for rain collection and rain storage. It monitors the water level of aqueduct 1, wells, four-level canal system and drainage pond in real time through water level sensors, monitors the water flow at various points in the system through flow sensors, monitors the soil moisture content of farmland through soil moisture sensors, transports water resources through water pumps and drainage pumps, and realizes water release and water stop through solenoid valves, thereby achieving precise allocation and control of water resources.

[0039] The intelligent management and control platform adopts the existing mature Alibaba Cloud Industrial Internet Platform (IoT Internet of Things Platform), eliminating the need for self-developed core management and control functions. This platform is a widely used industrial-grade cloud management and control platform on the market, possessing core capabilities such as rapid device access, massive data aggregation, remote and precise control, intelligent analysis and decision-making, and full-process operation and maintenance management. It can be directly adapted to various devices in this system, significantly reducing system development costs, shortening deployment cycles, and improving management and control stability and compatibility. The platform is deployed in the cloud to achieve remote centralized management and control of all devices in the system.

[0040] The present invention discloses a smart agricultural energy storage irrigation and drainage water-saving drip irrigation system, comprising the following steps: Step 1: Initialization and Parameter Preset Relying on the existing Alibaba Cloud Industrial Internet IoT platform, all devices are connected to the network and bound, and 5G+LoRa communication links are established to enable real-time data uploading and remote command reception from drones, water pumps, hydroelectric generators, solenoid valves, sensors, etc. The intelligent management and control platform presets thresholds, including rainfall linkage trigger values, low-level water replenishment thresholds for aqueduct 1, high-level drainage thresholds for drainage ponds, irrigation start / stop thresholds based on farmland soil moisture, and flow distribution parameters for pipelines at all levels. The platform is configured with automatic scheduling logic: rainwater collection scheduling, water replenishment linkage scheduling, precise irrigation scheduling, waterlogging drainage scheduling, and dual-energy power generation complementary scheduling, thus solidifying the full-process automation strategy.

[0041] Step Two: Rainwater Harvesting and Storage Operations The intelligent management and control platform connects to meteorological data, identifies rainfall areas and effective rainfall signals around farmland, and automatically issues commands to dispatch a cluster of drones (DU3) to take off from base 4. Drones (DU3) use GPS to precisely fly to the rainfall area, collect rainwater through a funnel-shaped rainwater collection trough (6), and a solenoid valve closes to lock the drainage pipe (7) to prevent leakage. Once fully loaded, they return to a designated position above the aqueduct (1) along a preset route. The intelligent management and control platform issues an opening / closing command, opening the solenoid valve on the drainage pipe (7) to guide the collected rainwater into the segmented aqueduct (1) for storage. After water injection, the solenoid valve closes, and drones (DU3) automatically fly back to base 4 to recharge via a wireless charging unit. A water level sensor transmits real-time data on the water storage in the aqueduct (1), dynamically adjusting the number of drones (DU3) deployed to complete rainwater enrichment and storage as needed.

[0042] Step 3: Routine water replenishment and comprehensive water allocation operations The intelligent management and control platform monitors the water level of aqueduct 1 in real time. When the water level is lower than the preset low threshold, it automatically starts the water pump in the well to draw groundwater and replenish it to aqueduct 1 or the four-level canal system through the water pipeline to ensure sufficient basic water supply. Rainwater in aqueduct 1 is transported by gravity through gravity conveying pipe 22 via the bottom arc structure. When the terrain difference is insufficient, the platform starts the main water pump to transport water resources to the four-level canal system of main canal 8, branch canal 9, distribution canal 10, and farm canal 11 in stages. Flow sensors monitor the water flow data of each level of canal system and pipeline in real time. The intelligent management and control platform controls the pipeline solenoid valves and canal system solenoid valves to achieve precise allocation of water resources by zone and layer, and deliver them to the field irrigation nodes as needed. Step 4: Precision water-saving drip irrigation operation in farmland Soil moisture sensors collect real-time soil moisture data in the field and upload it to the intelligent management platform, comparing it with preset crop water requirement thresholds. When soil moisture falls below the irrigation lower limit, the intelligent management platform automatically activates the water delivery solenoid valve and matching water pump from the irrigation canal 11 to the drip irrigation belt 12, directing water resources to the drip irrigation belt 12 on both sides, providing simultaneous and uniform irrigation to both sides of each row of crops. During irrigation, the drip irrigation belt 12 is secured by the unit fixing frame 13 to prevent displacement and leakage. Flow sensors monitor the drip irrigation flow in real time to prevent water waste. When soil moisture reaches the suitable moisture range for crops, the water delivery solenoid valve and water pump are automatically shut off, suspending irrigation and achieving precise water-saving irrigation on demand.

[0043] Step 5: Automatic drainage operation for accumulated water in the field When farmland is flooded during the rainy season, the water flows into irrigation canal 11, then through branch canal 10, tributary canal 9, and main canal 8, eventually converging into the lowest drainage pipe and finally being directed to the drainage pond. Water level sensors in the drainage pond monitor the water level in real time. When the water level reaches a preset high threshold, the cloud platform automatically starts the drainage pump and opens the solenoid valve of the drainage pipe. The drainage pump discharges the water in the drainage pond to the regional public drainage system or natural water system. After the water level drops back to the safe threshold, the platform automatically shuts off the drainage pump and solenoid valve, completing the automated drainage process.

[0044] Step Six: Complete Clean Energy Self-Supply Operation When rainwater from the aqueduct 1 falls through the gravity transport pipe 22, the potential energy of the water flow drives the hydroelectric generator 20 on the support pier 2 to operate, converting the potential energy into electrical energy to power the drones 3, water pumps, drainage pumps, sensing equipment, and various electrical control components on site. When there is no rainwater flow on sunny days and the hydroelectric power generation efficiency is insufficient, the solar photovoltaic panels 23 on the outside of the mounting base 21 start photovoltaic power generation, forming a complementary power supply mode with hydroelectric power generation. Surplus electrical energy can be stored in energy storage batteries (which can be installed on the support pier 2) to achieve peak shaving and valley filling of electrical energy. The entire system (excluding the intelligent management and control platform) prioritizes the use of self-generated clean energy to reduce the use of external grid electricity and achieve long-term energy saving and cost reduction.

[0045] During the water resource regulation process, the Alibaba Cloud Industrial Internet Platform aggregates real-time data on water level, flow rate, soil moisture, power generation, and equipment operating status 24 / 7, providing a visual overview of the system's operation. It can automatically identify issues such as equipment malfunctions, pipeline blockages, sensor failures, and pump overloads, sending out real-time alerts and supporting remote viewing and manual intervention by management personnel via mobile devices and PCs.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
