Description

Technical Field

[0001] This utility model relates to the field of farmland water-saving irrigation technology, specifically a pilot-scale device for the research and verification of farmland water-saving irrigation. Background Technology

[0002] Water-saving irrigation technology for farmland is a key support for achieving sustainable agricultural development and national food security strategies. With the increasingly severe water shortage problem, integrated water and fertilizer management, safe reuse of reclaimed water, and off-grid energy-driven technologies have become the core directions of water-saving irrigation research and development.

[0003] Current technology verification methods have fundamental limitations: traditional field trials are constrained by factors such as long crop growth cycles, significant environmental disturbances, and destructive sampling, making it difficult to quickly obtain dynamic data. While scaled-down simulations of industrial equipment can accelerate the experimental process, their fixed design makes them unsuitable for verification in multivariate scenarios. Pilot-scale devices, as a necessary link between laboratory research and large-scale field application, can quickly optimize and iterate parameters to assess the feasibility and economic viability of the technology. However, existing technologies lack suitable pilot-scale devices to comprehensively simulate the process of water-saving irrigation in farmland, making it difficult to simultaneously meet the research and development needs of "process visualization," "multi-parameter linkage control," and "rapid scenario reconstruction." There is an urgent need for a multivariate verification pilot-scale device specifically designed for agricultural water-saving irrigation research and development to fill this technological gap. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pilot-scale device for the research and development of water-saving irrigation for farmland, thus solving the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a pilot-scale device for multi-experiment research and verification of water-saving irrigation in farmland, comprising a platform component. The platform component includes a frame, with multiple sets of casters fixedly installed at the bottom for frame movement. A water supply component, a fertilization component, an irrigation component, a water purification and reuse component, a control component, and a solar panel are fixedly installed on the platform component. The water supply component, fertilization component, irrigation component, and water purification and reuse component are interconnected and transport materials via pipes and pumps. Rubber flexible joints connect the pipes. The control component controls the devices within the pilot-scale device. The irrigation component includes a simulation box fixed to the frame, used to simulate crop cultivation, irrigation, and fertilization. The water supply component supplies water to the simulation box, and the fertilization component applies fertilizer to the simulation box. The fertilization component's application of fertilizer to the simulation box allows the pilot-scale device for multi-experiment research and verification of water-saving irrigation in farmland to better simulate farmland conditions, thus improving the practicality of the device.

[0006] Furthermore, the water supply assembly includes a raw water tank fixedly installed at the rear left side of the frame. A self-priming dissolved air pump is fixedly installed on the upper surface of the raw water tank. The water supply assembly also includes an air vent valve, a check valve, a flow meter, a Y-type filter, an electric three-way valve, and a disc filter located on the frame. The water supply assembly also includes a bottom valve located at the bottom of the raw water tank. The water supply assembly also includes a pressure gauge located at the inlet of the self-priming dissolved air pump. The bottom valve is used to intercept scum in the water and protect the self-priming dissolved air pump and the entire pipeline network. The outlet of the self-priming dissolved air pump is connected to a transparent rigid pipe. After the water flows through the outlet of the self-priming dissolved air pump, it passes sequentially through the air vent valve, check valve, flow meter, Y-type filter, electric three-way valve, and disc filter before entering the irrigation assembly. The other outlet of the electric three-way valve is connected to the fertilizer assembly. The connection between the other outlet of the electric three-way valve and the fertilizer assembly improves the smoothness of the internal structure of the pilot-scale device for water-saving irrigation in farmland.

[0007] Furthermore, the fertilization assembly includes a fertilizer tank located at the front end of the original water tank. The assembly also includes a proportioning pump fixedly mounted on a frame. The pump's suction inlet is connected to the fertilizer tank via a hose, its inlet is connected to the water supply assembly via an electric three-way valve, and its outlet is connected to a filter. The filter's output is connected to the irrigation assembly. The fertilization assembly also includes a float level switch located inside the fertilizer tank. A fixing plate is fixedly mounted on the top of the fertilizer tank, and a speed-regulating motor is fixedly mounted on the fixing plate. A stirring rod is located at the lower end of the speed-regulating motor, inside the fertilizer tank. The stirring rod's location within the fertilizer tank allows for rapid agitation of the materials, improving the efficiency of the pilot-scale testing device for water-saving irrigation in farmland.

[0008] Furthermore, the irrigation assembly includes a pressure reducing valve, a solar solenoid valve, and an irrigation network. The liquid input from the raw water tank and the fertilizer tank passes through the solar solenoid valve and the pressure reducing valve in sequence before entering the irrigation network set in the simulation box. The irrigation network mainly includes sprinkler irrigation, drip irrigation, and seepage irrigation.

[0009] Furthermore, the water purification and reuse assembly includes a rainwater pipe network located on the simulation tank and an outer shell fixedly installed at the upper left end of the frame. The rainwater pipe network is used to send wastewater or rainwater generated by the simulation tank into the outer shell. Multiple filling layers are movably arranged inside the outer shell. The filling layers are filled from top to bottom with coarse quartz sand, fine quartz sand, activated carbon, and biological purification filler.

[0010] Furthermore, the control components include a housing fixedly mounted on a frame. A touchscreen, a pH sensor, a function meter, a conductivity meter, and a controller are located at the front end of the housing. The touchscreen, pH sensor, function meter, and conductivity meter are all electrically connected to the controller. The touchscreen displays both an operating software interface and an alarm monitoring interface. These interfaces enhance the intelligence of the pilot-scale test device for water-saving irrigation in farmland.

[0011] Furthermore, the solar panel is electrically connected to the control component. This electrical connection allows the energy harvested by the solar panel to be quickly transferred to the control component, improving the energy efficiency of the pilot-scale device for water-saving irrigation in farmland. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention improves R&D efficiency through the collaborative innovation of seven core modular systems: platform components, water supply components, fertilization components, irrigation components, water purification and reuse components, control components, and solar panels. These systems include a transparent flow path system, a closed-loop water and fertilizer control platform, and an adjustable off-grid energy module. This allows the pilot-scale R&D device for water-saving irrigation in farmland to simultaneously meet the R&D needs of process visualization, multi-parameter linkage control, and rapid scenario reconstruction, thereby enhancing the practicality of the pilot-scale R&D device for water-saving irrigation in farmland.

[0022] Example

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A pilot-scale experimental device for water-saving irrigation in farmland includes a platform component 1. The platform component 1 includes a frame 11, with multiple sets of casters 12 fixedly installed at the bottom of the frame 11 for movement. A water supply component 2, a fertilization component 3, an irrigation component 4, a water purification and reuse component 5, a control component 6, and a solar panel 7 are fixedly installed on the platform component 1.

A self-priming dissolved air pump 22 is fixedly installed on the upper surface of the raw water tank 21. The water supply component 2 also includes an air vent valve 16, a check valve 15, a flow meter 17, a Y-type filter 18, an electric three-way valve 29, and a disc filter 20 located on the frame 11. The water supply component 2 also includes a bottom valve 24 located at the bottom of the raw water tank 21. The water supply component 2 also includes a pressure gauge 23 located at the inlet of the self-priming dissolved air pump 22. The bottom valve 24 is used to intercept scum in the water, protect the self-priming dissolved air pump 22 and the entire pipe network. The outlet of the self-priming dissolved air pump 22 is connected to a transparent rigid pipe, and the water flows through the self-priming dissolved air pump 22. After the outlet of the air pump 22, the water flows sequentially through the exhaust valve 16, check valve 15, flow meter 17, Y-type filter 18, electric three-way valve 29, and disc filter 20 before entering the irrigation assembly 4. The other outlet of the electric three-way valve 29 is connected to the fertilizer assembly 3. The fertilizer assembly 3 includes a fertilizer tank 31 located at the front end of the raw water tank 21. The fertilizer assembly 3 also includes a proportional pump 32 fixedly mounted on the frame 11. The suction inlet of the proportional pump 32 is connected to the fertilizer tank 31 via a hose, and the inlet is connected to the water supply assembly 2 via the electric three-way valve 29. The outlet is connected to a filter 27, and the output of the filter 27 is connected to the irrigation assembly 4. The fertilizer assembly 3 also includes a float level switch 33 located inside the fertilizer tank 31. A fixing plate 35 is fixedly installed on the top of the fertilizer tank 31. A speed-regulating motor 36 is fixedly installed on the fixed plate 35. A stirring rod 34 is provided at the lower end of the speed-regulating motor 36. The stirring rod 34 is located inside the fertilizer box 31. The irrigation component 4 includes a pressure reducing valve 42, a solar solenoid valve 44, and an irrigation network 43. The liquid input from the raw water tank 21 and the fertilizer box 31 enters the irrigation network 43 set in the simulation box 41 after passing through the solar solenoid valve 44 and the pressure reducing valve 42 in sequence. The irrigation network 43 mainly includes sprinkler irrigation, drip irrigation, and seepage irrigation. The water purification and reuse component 5 includes a rainwater network 51 located on the simulation box 41 and a shell 53 fixedly installed on the upper left end of the frame 11. The rainwater network 51 is used to send wastewater or rainwater generated by the simulation box 41 into the shell 53.

The touchscreen 62, pH sensor 63, function meter 64, and conductivity meter 65 are all electrically connected to the controller 66. The touchscreen 62 has an operating software interface and an alarm monitoring interface. The solar panel 7 is electrically connected to the control component 6.

[0024] The working principle of the controller 66 can be divided into four basic steps: input, processing, output, and feedback. First, the controller 66 receives input signals from external devices or users, such as button presses or information detected by sensors. Next, the controller 66 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of the external devices. Since the controller 66 and the electronic components in the pilot test device for water-saving irrigation in farmland are electrically connected, the controller 66 can directly control the components in the pilot test device for water-saving irrigation in farmland. Furthermore, the controller 66 and its internal microcontroller chip are mature existing technologies, so this utility model does not elaborate on them.

[0025] In this application, since the components inside the pilot-scale devices for water-saving irrigation in farmland are all mature existing technologies, and this utility model only connects and utilizes them, the technical solution of this application does not improve them and does not affect the integrity of the technical solution of this application; and the parts not involved or not disclosed in detail are the same as the existing technology or are implemented using the existing technology.

[0026] The control component 6 mainly consists of a power control box, a touch screen 62, a pH sensor 63, a function table 64, a conductivity meter 65, a power switch, and a controller 66. It is equipped with a user-friendly and easy-to-use software interface and an alarm monitoring interface to control the entire pilot device and monitor key parameters in real time.

[0027] Among them, the solar panel 7 is connected to multiple corresponding lines for solar energy storage, powering the system and achieving energy-saving effects, and the energy can be directly transferred to the control component 6.

[0028] All enclosures and pipes are made of transparent material, making it easy to observe system operation and pipe network blockage. All joints are made of rubber flexible joints, which have the effect of flexibility and slight twisting, and are used to reduce the damage to the pipes caused by water pump vibration.

[0029] The working principle of this utility model is explained below: When using the pilot-scale test device for water-saving irrigation in farmland, different lighting areas in the laboratory can be switched for testing via the frame 11 and casters 12. The water supply system supplies water from the raw water tank 21 to the simulated farmland via a water pump. The self-priming dissolved air pump 22 is fixed to the upper surface of the raw water tank 21, providing the power for the entire water supply. No water filling is required, avoiding cavitation in the pump, and simultaneously achieving oxygenation in the water, promoting crop growth. In the raw water tank 21… The inlet of the self-priming dissolved air pump 22 is sequentially equipped with a foot valve 24 and a pressure gauge 23. The foot valve 24 intercepts scum in the water, protecting the pump and the entire pipe network. The outlet of the self-priming dissolved air pump 22 is connected to a transparent rigid pipe, which sequentially passes through an air vent valve 25, a check valve 26, a flow meter 27, a Y-type filter 28, an electric three-way valve 29, and a disc filter 210 before connecting to the irrigation assembly 4. The other outlet of the electric three-way valve 29 is connected to the fertilization system. A valve and a buffer pipe are installed before the pressure gauge for protection, extending the service life of the pressure gauge and providing additional protection. With the advantage of non-stop maintenance, the fertilization component 3 delivers the liquid fertilizer prepared in the fertilizer tank 31 to the irrigation component 4 via the proportioning pump 32. The stirring rod 34 can effectively stir the material inside the fertilizer tank 31. The liquid input from the raw water tank 21 or the fertilizer tank 31 passes through the solar solenoid valve 44 and the pressure reducing valve 42 before entering the irrigation network 43 set in the simulation box 41. The irrigation network mainly includes sprinkler irrigation, drip irrigation, and seepage irrigation, which can simulate different irrigation modes. The water purification and reuse component 5 collects the wastewater generated by the simulation box 41 through the rainwater network 51. Rainwater can be purified and reused within the outer shell 53 and filling layer 52 to achieve water conservation. The outer shell 53 and filling layer 52 adopt a drawer-type design, filled from top to bottom with coarse quartz sand, fine quartz sand, activated carbon, and biological purification filler. This can be adjusted as needed. Through the combination of the above structures, the pilot-scale test device for farmland water-saving irrigation can simultaneously meet the research and development needs of process visualization, multi-parameter linkage control, and rapid scene reconstruction, thereby improving the practicality of the pilot-scale test device for farmland water-saving irrigation.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
