Description

Technical Field

[0001] This application relates to the technical field of water conservancy irrigation, and particularly to a water conservancy irrigation diversion design structure. Background Art

[0002] When conducting water conservancy irrigation, it is often necessary to use an irrigation water diversion structure to control the direction of water flow and the irrigation area. In existing water conservancy irrigation systems, most irrigation water diversion structures are usually relatively simple. Usually, diversion pipes are used for water diversion, and flanges are commonly used as connectors between the diversion pipes. The ends of the water diversion pipes are threadedly connected to the flanges, which can only achieve water diversion in fixed directions and fixed ratios, and cannot be flexibly adjusted according to factors such as crop water requirements and weather changes, resulting in serious waste of water resources. Utility Model Content

[0003] In order to solve the problem that most irrigation water diversion structures in existing water conservancy irrigation systems are usually relatively simple and cannot be flexibly adjusted according to factors such as crop water requirements and weather changes, this application provides a water conservancy irrigation diversion design structure.

A number of diversion branch pipes are provided on the water supply main pipe for irrigation water diversion. A monitoring unit is provided on the diversion branch pipes, and a water flow regulating assembly is also provided on the diversion branch pipes. The water flow regulating assembly includes a pressure regulating valve provided on the diversion branch pipe, which is used to adjust the water supply ratio of the diversion branch pipe for irrigation water diversion.

[0006] Preferably, the pressure regulating valve adopts a pressure regulating valve with a control actuator for automatic control or remote control.

[0011] Through the combined use of a water supply main pipe, shunt branch pipes, and a water flow regulation component, the control system of the irrigation is used to set the thresholds of soil humidity and air temperature. When the thresholds are reached, the control system starts the water supply facility, remotely controls the opening and opening ratio of the corresponding pressure regulating valve, and ensures the stable water pressure in the shunt branch pipes through a pressure stabilizing valve. The water flow sensor measures the water supply volume.

[0016] The following further elaborates on the present application Figures 1-3 in further detail.

[0017] An embodiment of the present application discloses a water conservancy irrigation shunt design structure. Referring to Figures 1-2 , a water conservancy irrigation shunt design structure, a water supply main pipe 1 connected to the water outlet end of the water supply facility, several shunt branch pipes 2 are installed on the water supply main pipe 1, a water flow regulation component 3 is installed on the shunt branch pipes 2, the water flow regulation component 3 includes a pressure regulating valve 301 installed on the shunt branch pipe 2, and the pressure regulating valve 301 adopts a pressure regulating valve with a control actuator, and the control actuator can be selected as electric control or pneumatic control according to needs;

[0018] The pressure stabilizing valve 302 is installed downstream of the pressure regulating valve 301 through a pipeline, and the pressure stabilizing valve 302 stabilizes the water pressure in the pipeline located downstream, avoiding the influence of unstable water pressure on the irrigation effects of sprinkler irrigation, drip irrigation, sub-surface irrigation, and micro-irrigation, and at the same time improving the monitoring effect of the water flow sensor 303;

[0019] Downstream of the pressure stabilizing valve 302 is connected to a monitoring unit through a pipeline. The monitoring unit includes a water flow sensor 303 installed on the shunt branch pipe 2. The water flow sensor 303 is used to monitor the water flow of the shunt branch pipe 2 in real time, facilitating the precise control of the pressure regulating valve 301 by the control system and avoiding waste of water sources.

[0020] The water supply facility, pressure regulating valve 301, and water flow sensor 303 can establish communication with the irrigation control system. The irrigation control system is used to set the soil humidity and air temperature thresholds. When the thresholds are reached, the control system starts the water supply facility, remotely controls the opening of the corresponding pressure regulating valve 301 and the opening ratio, and ensures the stable water pressure in the shunt branch pipe 2 through the pressure stabilizing valve 302. The water flow sensor 303 measures the water supply volume. After reaching the water supply threshold or soil humidity threshold, the pressure regulating valve 301 on the corresponding shunt branch pipe 2 is closed to stop irrigation, achieving flexible control of the irrigation shunt ratio. Refer to Figure 3 , the irrigation control system can be composed of a meteorological monitoring system installed beside the water supply facility and a soil monitoring module in the irrigation area;

[0021] Among them, the meteorological monitoring system can be composed of a controller equipped with an STM32 series chip, an AI processing module of the NVIDIA Jetson series, and a temperature and humidity sensor. It can use machine learning algorithms to predict the crop water demand and weather change trend based on historical data, adjust the irrigation strategy in advance, and can also add a rain drop sensor according to requirements to monitor the rainfall amount to obtain more comprehensive information to support decision-making.

[0022] The implementation principle of a water conservancy irrigation shunt design structure in an embodiment of this application is as follows:

[0023] In the irrigation control system, set the thresholds of soil humidity and air temperature, as well as the start and stop conditions of irrigation. Use the meteorological monitoring system to collect temperature and humidity data in real time, and analyze and predict the weather change trend and crop water demand through the AI processing module. The soil monitoring module monitors the soil humidity in the irrigation area and feeds the data back to the irrigation control system. The water flow sensor 303 monitors the water flow of each shunt branch pipe 2 in real time to ensure the accuracy and real-time nature of the data.

[0024] When the meteorological monitoring system predicts that the crops need water or the soil monitoring module detects that the soil humidity is lower than the set threshold, the irrigation control system starts the irrigation process. The control system adjusts the opening ratio of the pressure regulating valve 301 through remote control according to the soil humidity, weather prediction, and irrigation demand, and controls the water supply volume from the water supply main pipe 1 to each shunt branch pipe 2. The water flow sensor 303 continuously monitors the water flow, and the data is fed back to the control system in real time, realizing precise control of the pressure regulating valve 301 and avoiding waste of water sources.

[0025] When the set soil humidity threshold or water supply threshold is reached, the control system closes the corresponding pressure regulating valve 301 to stop irrigation.

[0026] After irrigation, the system records the data of this irrigation (such as water consumption, irrigation duration, soil humidity change, etc.), providing data support for optimizing subsequent irrigation strategies.
