Description

Technical Field

[0001] This invention relates to a modular water and fertilizer integrated sprinkler irrigation device. Background Technology

[0002] With the development of modern agriculture, integrated water and fertilizer irrigation technology has been widely used in farmland irrigation and fertilization. Existing integrated water and fertilizer sprinkler irrigation systems are usually constructed on-site with customized methods, resulting in low integration between functional units, long construction cycles, strong dependence on site conditions, and difficulties in later maintenance and expansion.

[0003] Meanwhile, existing systems often employ a decentralized layout for water treatment, fertilization, mixing, distribution, and field execution, with inconsistent interface types. This leads to redundant construction during system upgrades, expansions, or cross-regional deployments. Furthermore, some systems lack sufficient consideration for the coordinated layout of pipelines and control lines, which can easily increase construction complexity and operation and maintenance costs.

[0004] Therefore, there is an urgent need for a water and fertilizer integrated sprinkler irrigation device with a clear structure, standardized interfaces, and easy integration and expansion, in order to improve the system's versatility, construction efficiency, and operational reliability. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a modular water and fertilizer integrated sprinkler irrigation device.

[0006] The modular water and fertilizer integrated sprinkler irrigation device includes a water source and water storage module, a fertilizer supply and fertilizer distribution module, a water and fertilizer mixing and central control module, a transmission and distribution pipeline module, and a field irrigation execution module. The water source and storage module includes a water storage tank or water tank, a water intake pumping station, a primary filtration system, a pressure stabilizing tank, and matching valves and fittings. The water source and storage module is equipped with a standardized water supply outlet flange and integrates a local monitoring unit. The local monitoring unit is equipped with an industrial data interface for connecting to the central control unit. The fertilizer supply and blending module includes several fertilizer solution mixing tanks, mother liquor storage tanks, metering pump sets, electric stirrers, liquid level sensors and connecting pipelines. The fertilizer supply and blending module is equipped with a mother liquor output port, which is connected by quick-connect or flange. The water and fertilizer mixing and central control module includes a mixing unit and a central control unit. The mixing unit integrates a proportioning pump, an EC / pH monitor, an electric regulating valve, and a pressure gauge. The central control unit adopts a PLC controller and integrates a touch screen, a network switch, and a power distribution unit. The aforementioned distribution network module includes a main pipeline module, branch pipeline modules, valve modules, and water supply valve modules. The main pipeline module includes a prefabricated pressure pipeline section of predetermined length, with standard socket or flange joints at both ends. The branch pipeline module has the same structure as the main pipeline but a smaller diameter and is used for regional distribution. The valve module includes electric / electromagnetic zone valves, pressure relief valves, and air release valves, all of which are pipe-type installation components that can be directly connected to the pipeline network. The water supply valve module includes a standardized field outlet with valves and quick connectors that can be directly connected to the next-level field irrigation execution module. The field irrigation execution module includes an electric ball valve, a pressure regulator, a flow meter, several sprinklers, and their supporting poles.

[0007] As a further improvement, the local monitoring unit includes sensors for monitoring water level, pressure, and water quality. Setting water level, pressure, and water quality sensors in the water source and storage modules facilitates real-time monitoring of the water supply status and improves the safety and stability of system operation.

[0008] As a further improvement, the aforementioned skid-mounted mixing equipment is also equipped with a water source inlet, a mother liquor inlet, and a mixed liquor outlet, all of which use standard flange interfaces. The mixing unit is equipped with standardized water source inlet, mother liquor inlet, and mixed liquor outlet, which facilitates quick connection and replacement between different modules and improves the versatility of the system.

[0009] As a further improvement, the prefabricated pressure pipeline section in the aforementioned transmission and distribution network module is pre-installed with conduits for laying communication cables, and waterproof wiring compartments connected to the conduits are reserved at both ends of the joints. By pre-installing communication cable conduits and setting up waterproof wiring compartments in the prefabricated pressure pipeline section, the synchronous laying of pipelines and control lines is realized, reducing construction difficulty and improving system reliability.

[0010] As a further improvement, the water and fertilizer mixing and central control module adopts a skid-mounted structure, integrating the mixing unit, detection instruments, and control cabinet onto a common base, forming an independent functional unit that can be transported and hoisted as a whole. The skid-mounted structure integrates the mixing unit, detection instruments, and control cabinet onto a common base, which facilitates overall transportation, hoisting, and rapid on-site installation, reducing the amount of on-site integration work.

[0011] As a further improvement, the fertilizer solution mixing tank of the fertilizer supply and mixing module is equipped with an automatic water inlet, fertilizer addition and mixing control system based on weight or liquid level sensors. The fertilizer solution mixing tank is equipped with an automatic water inlet, fertilizer addition and mixing control system, which improves the automation level and proportioning accuracy of fertilizer solution preparation and reduces the intensity of manual operation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Modular design: By dividing functions such as water source, fertilizer supply, mixing control, distribution and field execution into independent modules, the system can be standardized and combined to facilitate rapid deployment in different scales and application scenarios.

[0013] Standardized interfaces: The modules are connected using standard interfaces such as flanges and quick-connects, which reduces the difficulty of on-site installation and improves the system's compatibility and maintainability.

[0014] Strong centralized monitoring and control capabilities: The central control unit can centrally monitor and regulate water and fertilizer mixing parameters and operating status, thereby improving the stability of water and fertilizer ratio and the controllability of irrigation operations.

[0015] Pipeline and communication network deployment: Reserving communication cable channels in the transmission and distribution pipeline network is beneficial for unified wiring of equipment such as valves and sensors, reducing repeated construction.

[0016] Good adaptability and scalability: The system can flexibly add or remove modules according to the scale of farmland, and is suitable for a variety of agricultural irrigation application scenarios. Attached Figure Description
