Description

Technical Field

[0001] This utility model relates to the technical field of integrated water and fertilizer irrigation equipment, specifically to a multi-channel irrigation system that integrates online and fertilizer storage. Background Technology

[0002] Currently, agricultural production is rapidly developing towards intensification and precision. Integrated water and fertilizer irrigation technology, as a core means to improve resource utilization and ensure crop yield and quality, has become an important development direction for modern agriculture. However, existing integrated water and fertilizer systems still face many technical bottlenecks in adapting to different planting scenarios, meeting diverse irrigation needs, and balancing detection accuracy with ease of operation. They are unable to fully meet the current agricultural production's demands for efficient, flexible, and precise irrigation. Specifically, the following problems exist: Traditional irrigation and fertilization methods are inefficient, leading to resource waste and environmental pollution. In my country, traditional agricultural fertilization still relies heavily on surface application and manual topdressing, which is labor-intensive and difficult to control precisely. This results in an actual fertilizer utilization rate of only about 30%, with large amounts of fertilizer lost through seepage and volatilization. This not only causes significant waste of fertilizer resources but also triggers a chain reaction of problems such as soil compaction, groundwater pollution, and air pollution. Furthermore, traditional irrigation and fertilization processes are independent, with irrigation water utilization rate at only about 43% and grain yield per unit volume of water less than 10 kg, significantly lagging behind international advanced levels (over 20 kg). The contradiction between water scarcity and inefficient utilization is intensifying, severely hindering sustainable agricultural development.

[0003] Existing integrated water and fertilizer systems suffer from a lack of adaptability and flexibility due to their simplistic design. Most current integrated water and fertilizer systems on the market employ a single fertilizer supply model: one type relies on online mixing, depending on real-time water and fertilizer ratios, but its limited pipeline structure makes it difficult to meet the differentiated irrigation needs of multiple regions and crops; another type uses a fertilizer storage tank as its core, which, while allowing for pre-mixing of specific fertilizer concentrations, suffers from drawbacks such as fertilizer deterioration during storage and the inability to adjust the formula based on crop growth dynamics. Furthermore, existing systems are mostly designed for small-scale planting, with a fixed number of pipeline channels (e.g., most systems only support 2-4 irrigation pipelines). When applied to large-scale planting scenarios such as greenhouse vegetables and orchards, multiple sets of equipment need to operate in parallel, increasing equipment investment costs and system control complexity. This can lead to problems such as poor irrigation uniformity and inconsistent water and fertilizer ratios, making it difficult to meet the needs of multi-channel, multi-region coordinated irrigation. Utility Model Content

[0004] The purpose of this utility model is to address the problems of the current integrated water and fertilizer system having a single mode, insufficient adaptability and flexibility, and to provide a multi-channel irrigation system that integrates online and fertilizer storage, combining two irrigation modes into one, thus solving the problems of a single irrigation mode, poor flexibility and inability to achieve multi-area coordinated irrigation.

[0005] The technical solution of this utility model is as follows: A multi-channel irrigation system integrating online and fertilizer storage includes a main control box and an inlet centrifugal pump. The inlet centrifugal pump is connected to a water tank and is sequentially connected to at least two mother liquor tank structures, a static mixer, a mixed liquor EC sensor, and a mixed liquor pH sensor. The mixed liquor EC sensor and the mixed liquor pH sensor are connected to a first irrigation zone and are sequentially connected to at least two fertilizer storage tank structures, a fertilizer storage tank centrifugal pump, a pressure sensor, a flow meter, and a second irrigation zone. Based on the EC and pH detection information collected by the mixed liquid EC sensor and mixed liquid pH sensor, the main control box controls the opening or closing of the solenoid valve and fertilizer diaphragm pump in the mother liquor tank structure to enter the online irrigation mode and irrigate the first irrigation area. Furthermore, after entering the online irrigation mode, the main control box equipment controls the opening or closing of the fertilizer storage tank solenoid valve, fertilizer storage tank electric valve, and fertilizer tank centrifugal pump in the fertilizer storage tank structure based on the EC and pH detection information collected by the mixed liquid EC sensor and mixed liquid pH sensor in the fertilizer storage tank structure, as well as the information from the fertilizer storage tank level gauge, pressure sensor, and flow meter, thus entering the fertilizer storage irrigation mode to irrigate the second irrigation area.

[0006] The above structure integrates the "online mixing" and "fertilizer storage" liquid supply processes into a single system via pipelines and other components, all centrally controlled by a main control box. Users can flexibly choose between real-time precision fertilization (online) or premixed fertilizer solution (storage) based on the needs of different crops and growth stages, overcoming the limitations of traditional systems with their single-mode operation. Furthermore, a single system can meet the diverse irrigation needs and timeliness requirements of different planting areas in large-scale farms, avoiding the high costs and complex control issues associated with multiple parallel systems.

[0007] Furthermore, the number of mother liquor tank structures is five, and each mother liquor tank structure includes a mother liquor tank, a solenoid valve and a fertilizer suction diaphragm pump that are matched with the mother liquor tank.

[0008] Furthermore, the number of fertilizer storage tank structures is four, and each fertilizer storage tank structure includes a fertilizer storage tank, a fertilizer storage tank solenoid valve, a fertilizer storage tank level gauge, and a fertilizer storage tank electric valve that are matched with the fertilizer storage tank.

[0009] Furthermore, the mother liquor tanks are respectively a first mother liquor tank, a second mother liquor tank, a third mother liquor tank, a fourth mother liquor tank, and a fifth mother liquor tank; wherein the first mother liquor tank, the second mother liquor tank, the third mother liquor tank, and the fourth mother liquor tank are fertilizer mother liquor tanks; and the fifth mother liquor tank is an acid-base mother liquor tank.

[0010] The above structure allows for the creation of multiple mother liquor tanks (e.g., four fertilizer tanks + one acid / alkali tank), each equipped with an independent solenoid valve and a fertilizer-absorbing diaphragm pump. This enables the formulation of fertilizers with various proportions and compositions to meet the needs of precision agriculture. Independent fertilizer absorption channels prevent the mixing of different mother liquors at the source, ensuring the purity and accuracy of the formulation.

[0011] Furthermore, the first irrigation zone controls different irrigation zones through the fifth, sixth, seventh, and eighth irrigation solenoid valves.

[0012] Furthermore, the second irrigation zone controls different irrigation zones through the first irrigation solenoid valve, the second irrigation solenoid valve, the third irrigation solenoid valve, and the fourth irrigation solenoid valve.

[0013] Furthermore, the main control box is configured to receive signals from the first fertilizer tank level gauge, the second fertilizer tank level gauge, the third fertilizer tank level gauge, and the fourth fertilizer tank level gauge in the fertilizer tank structure, and control the opening and closing of the first fertilizer tank solenoid valve, the second fertilizer tank solenoid valve, the third fertilizer tank solenoid valve, and the fourth fertilizer tank solenoid valve in the fertilizer tank structure accordingly.

[0014] The above structure incorporates multiple fertilizer storage tanks, each equipped with an inlet solenoid valve, an outlet electric valve, and a level gauge, all sharing a common centrifugal pump. This allows for the pre-preparation and storage of various fertilizer solutions for immediate use, achieving "one-time preparation, multiple uses," making it particularly suitable for rotating irrigation of multiple crops. The level gauge and solenoid valve are linked for automatic shut-off, preventing overflow; the system structure also avoids pump idling. Sealed storage reduces fertilizer evaporation and external contamination, offering significant advantages over open-air storage.

[0015] Furthermore, the EC sensor and pH sensor of the mixed liquid detect the EC and pH of the mixed liquid. When the EC and pH values ​​of the mixed liquid reach the set values, the fifth irrigation solenoid valve, the sixth irrigation solenoid valve, the seventh irrigation solenoid valve and the eighth irrigation solenoid valve are opened in sequence to irrigate different irrigation areas.

[0016] With the above structure, EC and pH sensors are installed after the static mixer to directly monitor the mixture to be irrigated. This achieves closed-loop control of the water-fertilizer mixing process, ensuring that the EC / pH values ​​of the irrigation solution accurately meet the set requirements, thus improving the precision of fertilization. It also prevents the irrigation of substandard fertilizer solutions from the source, directly reducing water and fertilizer waste caused by inaccurate mixing ratios.

[0017] Furthermore, the pressure sensor and flow meter can monitor the pipeline pressure and irrigation flow of the fertilizer storage irrigation system in real time.

[0018] Furthermore, the system controls the opening and closing of relevant valves and pumps through the main control box equipment, so as to directly deliver the mixed fertilizer solution to the irrigation branch or store it in a designated fertilizer storage tank.

[0019] With the above structure, the main control box acts as the brain, electrically connecting to all sensors and actuators (pumps, valves). Users can easily switch irrigation modes, select formulas, and choose irrigation areas with a single click through the software interface, greatly reducing operational difficulty and labor costs. The system can automatically execute complex fertilizer mixing, storage, and irrigation processes, and automatically adjust based on sensor feedback, making it the core of precision agriculture and intelligent irrigation.

[0020] Compared with existing technologies, the beneficial effects of this utility model are: This system achieves the technical effect of combining online and fertilizer storage in a single irrigation system. In some large-scale planting scenarios with high requirements for water and fertilizer irrigation, it achieves the purpose of saving water and fertilizer, and has diversified modes and is easy to operate; it fills the problem of the single water and fertilizer irrigation mode in the existing market.

[0031] The system controls the opening and closing of relevant valves and pumps through the main control box device 1, so as to directly deliver the mixed fertilizer solution to the irrigation branch or store it in a designated fertilizer storage tank.

[0032] Working principle: Online Irrigation Mode: After the system is activated and the online irrigation mode is started, the inlet centrifugal pump 2 will be turned on. The system consists of four fertilizer mother liquor tanks and one acid / alkali mother liquor tank, which are configured to open the first mother liquor tank 3, the second mother liquor tank 4, the third mother liquor tank 5, the fourth mother liquor tank 6, and the fifth mother liquor tank 7. The user adds fertilizers of different formulations to the first mother liquor tank 3, the second mother liquor tank 4, the third mother liquor tank 5, and the fourth mother liquor tank 6, and adds acid / alkali solution to the fifth mother liquor tank 7. Then, according to the irrigation formula requirements, the system opens the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13, the fourth solenoid valve 14, and the fifth solenoid valve 15 of the different mother liquor tanks. Solenoid valves 14, 15, 16, 17, 18, 19, and 20 mix clean water, mother liquor, and acid / alkali solution. After passing through the static mixer 8 in the pipeline, EC sensor 9 and pH sensor 10 detect the EC and pH of the mixture.
