[0021] like Figures 1 to 3 As shown, this embodiment of the IoT-based farmland irrigation water-saving control device includes a water-saving control pipe 1, which is installed on the irrigation pipe 8 via an installation mechanism. A water-saving plate 2 is installed inside the water-saving control pipe 1, and the top of the water-saving plate 2 is connected to an actuator 3 via a rotating shaft. A flow meter 4 is installed on one side of the water-saving control pipe 1, and the flow meter 4 is connected to the actuator 3. The actuator 3 is connected to a control terminal via a communication module. A filter screen 5 is installed inside the water-saving control pipe 1 on the other side of the water-saving plate 2, and a cleaning mechanism is installed on the filter screen 5. A drain outlet 6 is installed at the bottom of the water-saving control pipe 1 on the side of the filter screen 5 away from the water-saving plate 2, and a drain valve is installed on the drain outlet 6. This enables IoT-based farmland irrigation water-saving control, improving the water-saving efficiency of farmland irrigation. The water-saving control pipe 1 has a water-saving filtration function, providing precise irrigation water-saving control. It also enables automatic cleaning and drainage of the filter surface of the filter screen 5 inside the water-saving control pipe 1, making cleaning convenient and providing strong anti-interference capabilities for water-saving control.
[0022] Specifically, the cleaning mechanism includes a cleaning plate 7, a cleaning brush 71, a connecting shaft 72, a worm gear 73, a worm 74, a connecting rod 75, and a servo motor 76. The cleaning plate 7 is located inside the throttling control pipe 1 on the side of the filter screen plate 5 away from the throttling plate 2. The cleaning brush 71 and the connecting shaft 72 are located on the side of the cleaning plate 7 closest to the filter screen plate 5. The connecting shaft 72 passes through the filter screen plate 5 via a shaft hole and connects to the worm gear 73. The worm 74 is located inside the throttling control pipe 1 on the side of the filter screen plate 5 away from the cleaning plate 7, via the connecting rod 75. 4 meshes with the worm gear 73. The top of the worm 74 is connected to the output end of the servo motor 76 through a coupling. The servo motor 76 is located on the top of the throttling control pipe 1 through a motor box. The servo motor 76 can rotate in both directions. The servo motor 76 drives the connecting rod 75 and the worm 74 to rotate. The rotation of the worm 74 drives the worm gear 73 that meshes with it to rotate. The rotation of the worm gear 73 drives the cleaning plate 7 and the cleaning brush 71 to rotate on the filter surface of the filter screen plate 5 through the connecting shaft 72, cleaning the dirt on the filter surface of the filter screen plate 5.
[0023] Furthermore, the actuator 3 consists of a first worm gear, a first worm, and an actuator motor. The first worm gear and the first worm mesh with each other. The first worm gear is connected to the throttling plate 2 via a rotating shaft. The output end of the actuator motor is connected to the first worm via a coupling. The output end of the flow meter 4 is electrically connected to the input end of the actuator motor via a control module. The actuator motor is connected to the control terminal via a communication module. The actuator motor can rotate in both directions. The irrigation flow data required for irrigation is input through the control terminal. According to the data input by the control terminal, the actuator motor of the actuator 3 drives the first worm to rotate. The rotation of the first worm drives the first worm gear meshing with it to rotate. The rotation of the first worm gear drives the throttling plate 2 to rotate inside the throttling control pipe 1 via the rotating shaft.
[0024] Furthermore, flow meter 4 adopts a Doppler ultrasonic flow meter, model HBY-400R. The Doppler ultrasonic flow meter uses the physical principle of Doppler frequency shift to measure the water flow velocity. Flow meter 4 accurately monitors the flow inside the throttling control pipe 1.
[0025] Furthermore, the installation mechanism includes flange 9 and flange 10. Flange 9 is provided at both ends of the throttling control pipe 1, and flange 10 is provided at the end of the irrigation pipe 8 near the throttling control pipe 1. Flange 9 and flange 10 are fixed together by bolts, making it easy to install between the throttling control pipe 1 and the irrigation pipe 8.
[0026] Furthermore, a sealing ring is provided between flange 9 and flange 10, a sealing gasket is provided between connecting rod 75 and throttling control pipe 1, a sealing gasket is provided between actuator 3 and throttling control pipe 1, flange 9 and flange 10 are assembled and sealed, connecting rod 75 and throttling control pipe 1 are sealed, actuator 3 and throttling control pipe 1 are sealed, and throttling control pipe 1 has good sealing performance, avoiding interference with irrigation throttling caused by leakage of throttling control pipe 1.
[0027] Furthermore, the inner wall of the throttling control pipe 1 is coated with a corrosion-resistant coating. A water quality monitoring probe is installed inside the throttling control pipe 1 on the side of the throttling plate 2 away from the filter screen plate 5. The output end of the water quality monitoring probe is connected to the input end of the actuator motor through the control module. The water quality monitoring probe is equipped with water quality detection sensors, including dissolved oxygen sensor, conductivity sensor, pH sensor, temperature sensor and chloride ion sensor. The water quality detection sensors on the water quality monitoring probe can detect the water quality of the irrigation water flowing through the throttling control pipe 1. When the irrigation water does not meet the standards, the irrigation water is not suitable for irrigation. This signal is transmitted to the control module, which controls the actuator motor to run. The actuator 3 drives the throttling plate 2 to close the throttling control pipe 1.
[0028] The usage method of this embodiment is as follows: Flange 9 and flange 10 are sealed together with bolts. The flow control pipe 1, equipped with a filter screen 5 and a flow throttling plate 2, is sealed and installed on the irrigation pipe 8. During farmland irrigation, the required irrigation flow rate data is input through the control terminal according to the irrigation needs. The actuator 3's motor drives the first worm gear to rotate according to the data input from the control terminal. The rotation of the first worm gear drives the first worm wheel meshing with it to rotate. The rotation of the first worm wheel drives the flow throttling plate 2 to rotate inside the flow control pipe 1 via a rotating shaft. The rotation of the flow throttling plate 2 opens the flow control pipe 1 for circulation. The flow meter 4 monitors the flow velocity inside the flow control pipe 1. When the flow meter 4 detects that the flow velocity inside the flow control pipe 1 reaches the required irrigation flow rate, the actuator motor stops driving the flow throttling plate 2, thus realizing farmland irrigation based on the Internet of Things. The irrigation throttling control operation improves the water-saving efficiency of farmland irrigation. The filter screen 5 installed inside the throttling control pipe 1 at the inflow end of the throttling plate 2 allows irrigation water to enter the throttling control pipe 1 and be filtered by the filter screen 5. The throttling control pipe 1 has a throttling and filtering function, and the irrigation throttling control is precise. The throttling control pipe 1 is closed by the actuator 3 and the throttling plate 2. The servo motor 76 drives the connecting rod 75 and the worm gear 74 to rotate. The rotation of the worm gear 74 drives the worm wheel 73 meshing with it to rotate. The rotation of the worm wheel 73 drives the cleaning plate 7 and the cleaning brush 71 to rotate on the filter surface of the filter screen 5 through the connecting shaft 72, cleaning the dirt on the filter surface of the filter screen 5. The drain valve on the drain outlet 6 is opened to discharge the wastewater. This realizes the automatic cleaning and sewage discharge of the filter surface of the filter screen 5 inside the throttling control pipe 1. The cleaning is convenient and the throttling control has strong anti-interference ability.
