Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a water-saving and drought-resistant intelligent irrigation system for rice. Background Technology

[0002] Rice is one of my country's main food crops, requiring a large amount of water during its growth. Traditional irrigation methods, such as flood irrigation, suffer from uneven irrigation, high labor costs, and significant water waste. Especially in hilly and mountainous areas or regions with limited irrigation water, traditional irrigation methods are ill-suited to rice's growth needs, leading to low yields and frequent late-stage diseases. While some existing irrigation systems attempt to monitor soil moisture and automatically control irrigation using sensors, they still have the following shortcomings: 1. Irrigation systems rely on mains power or batteries, resulting in limited endurance and hindering long-term operation in the field; 2. They lack comprehensive assessment of meteorological conditions and soil moisture, leading to simplistic irrigation decisions and water waste; 3. They fail to utilize the hydraulic resources within the irrigation channels, resulting in low system energy efficiency; 4. Filters lack self-cleaning mechanisms and have insufficient anti-clogging capabilities.

[0003] Therefore, there is an urgent need for a smart irrigation system for rice that integrates energy self-sufficiency, intelligent decision-making, efficient execution, and anti-blockage and cleaning functions. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a water-saving and drought-resistant intelligent irrigation system for rice, which solves the problems of low energy efficiency, poor anti-clogging ability, and limited application scope of existing irrigation systems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water-saving and drought-resistant intelligent irrigation system for rice is provided, comprising a shell, an irrigation channel located at the bottom of the shell, a sluice gate located within the irrigation channel, and an environmental sensing unit, a self-cleaning filtration unit, a power supply unit, and a control unit integrated on the shell. The environmental sensing unit includes a meteorological monitor for real-time collection of meteorological, soil, and water level data, a soil sensor, a water level gauge, and a water level evaporator. The self-cleaning filtration unit includes a filter screen located at the front end of the irrigation channel, a hydroelectric generator and a brush in contact with the filter screen located at the rear end of the filter screen, and the hydroelectric generator and brush are mounted on a lifting mechanism. The power supply unit provides power to the system, and the control unit collects environmental data and controls the opening and closing of the sluice gate, the hydroelectric generator, and the lifting mechanism.

[0006] Furthermore, the lifting mechanism includes a vertical rack that is slidably disposed within the housing, the vertical rack meshing with a gear, the gear being disposed on the rotating shaft of the drive motor, and the hydroelectric generator and brush being disposed at the bottom of the vertical rack.

[0007] Furthermore, the brush is a horizontally arranged strip structure, and the width of the brush is equal to the width of the filter screen.

[0008] Furthermore, the hydroelectric generator is a reversible water turbine that can reverse the flow of water.

[0009] Furthermore, the sluice gate includes two vertically spaced sluice gate baffles. Both sides of the sluice gate baffles are slidably mounted on vertical guide rails. The two sluice gate baffles are fixedly connected by a connecting plate. A telescopic rod is provided above the connecting plate, and the connecting plate is connected to the telescopic end of the telescopic rod via a transmission connection.

[0010] Furthermore, the upper surface of the connecting plate is provided with several limiting posts, the telescopic end of the telescopic rod is provided with a pressure plate, the several limiting posts slide through the pressure plate, the top of the limiting posts is provided with a limiting head for abutting against the pressure plate, and a spring is sleeved on the limiting post located between the pressure plate and the connecting plate.

[0011] Furthermore, the vertical guide rail is equipped with a guide rail rubber strip for sliding and sealing contact with the sluice gate baffle.

[0012] Furthermore, the bottom of the sluice gate is provided with a rubber plate for sealing contact with the bottom of the sluice gate baffle.

[0013] Furthermore, the power supply unit includes a solar panel mounted on the top of the casing, and both the solar panel and the hydroelectric generator are electrically connected to the battery.

[0014] Furthermore, a camera is installed on the casing.

[0015] The beneficial effects of this utility model are as follows: 1. This solution uses a meteorological monitoring instrument to collect meteorological parameters such as temperature, humidity, and light in real time, a soil sensor to accurately monitor the soil moisture in the paddy field, and a water level gauge to dynamically provide feedback on the field water level data, thereby achieving comprehensive monitoring of environmental parameters. Combined with the evaporation rate calculated by the water level evaporator, it provides data for judging the optimal irrigation time and amount, avoiding excessive or insufficient watering caused by traditional timed irrigation. At the same time, based on multi-source data, the system automatically opens the sluice gate after the paddy field water level drops, realizing unattended intelligent irrigation management.

[0016] 2. When the filter screen is clogged by moss or impurities, the hydroelectric generator can switch to battery power mode, driving the generator blades to reverse and generate reverse water flow. This, in conjunction with the drive motor and brush, performs an up-and-down cleaning action, thereby automatically removing the blockages from the filter screen surface, ensuring long-term unobstructed irrigation channels, and solving the clogging problem that is prone to occur in outdoor irrigation systems.

[0017] 3. The sluice gate in this solution forms a double-sealing structure through two sluice gate baffles, four vertical guide rails, guide rail rubber strips, and rubber plates, ensuring zero leakage when the sluice gate is closed; by setting a spring buffer mechanism, it can effectively deal with foreign objects such as small stones and branches when the sluice gate baffles are closed, preventing them from getting stuck and causing overload damage to the telescopic rod motor, thus improving the safety of system operation.

[0018] 4. This solution adopts a hybrid power supply mode of solar panels and hydroelectric generators. The solar panels serve as the main power source, providing clean electricity to the system and ensuring its continuous operation. When the sluice gate is opened for irrigation, the water flow drives the generator blades to rotate and generate hydroelectric power to charge the battery, thus realizing energy recovery and self-sufficiency, which greatly expands its application scope.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] like Figures 1 to 6 As shown, the proposed intelligent irrigation system for water-saving and drought-resistant rice includes a shell 1, an irrigation channel 2 located at the bottom of the shell 1, a water gate 3 located within the irrigation channel 2, and an environmental sensing unit, a self-cleaning filter unit, an energy supply unit, and a control unit integrated on the shell 1.

[0032] The environmental sensing unit includes a meteorological monitor 4, a soil sensor 5, a water level gauge 6, and a water level evaporator 7 for real-time acquisition of meteorological, soil, and water level data. The meteorological monitor 4 collects meteorological parameters such as temperature, humidity, and light in real time, the soil sensor 5 accurately monitors the soil moisture in the paddy field, and the water level gauge 6 dynamically feeds back the water level data in the field, thus achieving comprehensive monitoring of environmental parameters. In addition, a camera 24 can be installed on the housing 1 to provide images of the actual environment of the paddy field.

[0033] like Figure 3 and Figure 4 As shown, the self-cleaning filter unit includes a filter screen 8 located at the front end of the irrigation channel 2. A hydraulic generator 9 and a brush 10 in contact with the filter screen 8 are located at the rear end of the filter screen 8. The hydraulic generator 9 and the brush 10 are mounted on a lifting mechanism. The lifting mechanism includes a vertical rack 11 slidably mounted within the housing 1. The vertical rack 11 meshes with a gear 12, which is mounted on the shaft of the drive motor 13. The hydraulic generator 9 and the brush 10 are both located at the bottom of the vertical rack 11. The hydraulic generator 9 is a reversible water turbine that can reverse the flow of water. The brush 10 is a horizontally arranged strip structure, and its width is equal to the width of the filter screen 8. This solution... When the sluice gate 3 is opened, the drive motor 13 can drive the hydroelectric generator 9 to descend, thereby driving the blades 25 of the hydroelectric generator 9 to generate water power through the water flow. In addition, this solution can also achieve accurate measurement of water flow and irrigation volume by integrating the rotation speed of the blades 25 with the water level data. When the filter screen 8 is blocked by moss or impurities, the hydroelectric generator 9 can switch to battery power mode, drive the blades 25 of the hydroelectric generator 9 to reverse, generate reverse water flow, drive the motor 13 to rotate forward and reverse, and use the brush 10 to clean the filter screen 8 up and down, thereby automatically removing the blockage on the surface of the filter screen, ensuring that the irrigation channel 2 is unobstructed for a long time, and solving the problem of blockage that is prone to occur in the field irrigation system.

[0034] like Figure 5 and Figure 6 As shown, the sluice gate 3 of this scheme includes two vertically spaced sluice gate baffles 14. Both sides of the sluice gate baffles 14 are slidably mounted on vertical guide rails 15. Guide rail rubber strips 22 are provided inside the vertical guide rails 15 for sliding and sealing contact with the sluice gate baffles 14. A rubber plate 18 is provided at the bottom of the sluice gate 3 for sealing contact with the bottom of the sluice gate baffles 14. The two sluice gate baffles 14 are fixedly connected by a connecting plate 16. A telescopic rod 17 is provided above the connecting plate 16, and the telescopic ends of the connecting plate 16 and the telescopic rod 17 are connected in a transmission manner. Specifically, a plurality of limiting posts are provided on the upper surface of the connecting plate 16, and the telescopic ends of the telescopic rod 17 are provided with… There is a pressure plate 19, and several limiting posts slide through the pressure plate 19. The top of the limiting post is provided with a limiting head 20 for abutting against the pressure plate 19. A spring 21 is sleeved on the limiting post located between the pressure plate 19 and the connecting plate 16. The water gate 3 of this scheme forms a double sealing structure through two water gate baffles 14, four vertical guide rails 15, guide rail rubber strips 22 and rubber plates 18, which ensures zero leakage of water gate 3 in the closed state. By setting the spring 21 buffer mechanism, it can effectively deal with foreign objects such as small stones and branches when the water gate baffle 14 is closed, prevent them from jamming and causing overload damage to the motor of telescopic rod 17, and improve the safety of system operation.

[0035] The power supply unit is used to provide power to the system. The power supply unit includes a solar panel 23 installed on the top of the housing 1. Both the solar panel 23 and the hydroelectric generator 9 are electrically connected to the storage battery. This scheme adopts a hybrid power supply mode of solar panel 23 and hydroelectric generator 9. The solar panel 23 serves as the main power source, providing clean power to the system and ensuring continuous operation. When the sluice gate 3 is opened for irrigation, the water flow drives the blades 25 of the hydroelectric generator 9 to rotate and generate hydroelectric power to charge the storage battery. This realizes energy recovery and self-sufficiency, thereby greatly expanding its application range.

[0036] The control unit collects environmental data and controls the opening and closing of the sluice gate 3, the hydroelectric generator 9, and the lifting mechanism. Based on multi-source data, the system automatically opens the sluice gate 3 after the paddy field water level has receded, achieving unattended intelligent irrigation management. Simultaneously, the control unit can incorporate an intelligent computing module, combining climate conditions and the unit evaporation rate calculated by the water level evaporator 7 to provide data for judging the optimal irrigation timing and amount, avoiding excessive or insufficient watering caused by traditional timed irrigation. Furthermore, the system can execute an alternating wet and dry irrigation mode, ensuring the rice's water needs while allowing the soil to dry periodically. When rice needs to be dried to control tillering, ensuring the field surface is dry guarantees the effectiveness of tiller control, promotes rice root growth, enhances drought resistance, effectively inhibits ineffective tillering, and reduces field humidity, reducing diseases susceptible to high temperature and humidity, such as sheath blight, thus achieving water conservation and increased yield.

[0037] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, they should not be construed as limiting the scope of protection of this patent; various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims are still within the scope of protection of this patent.
