[0002] Irrigation is a crucial element in wheat cultivation, ensuring both growth and yield. Traditional irrigation methods, such as flood irrigation, result in significant water waste and uneven distribution, leading to water shortages in some areas and poor growth in others due to excessive moisture. Existing irrigation distribution equipment struggles to achieve precise and uniform water distribution across large wheat fields, failing to meet the varying water requirements of different growth stages. This negatively impacts overall growth and final harvest. Furthermore, irrigation water may contain sediment and impurities, easily clogging pipes and sprinkler heads. For instance, the small outlets of micro-sprinklers and drip irrigation systems allow impurities to enter, causing blockages, affecting irrigation efficiency, and reducing equipment lifespan.

Detailed Implementation

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] Example

[0018] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, a uniform water flow distributor for wheat field irrigation includes a main inlet pipe 1 and multiple branch water pipes 2, wherein the branch water pipes 2 are connected to the main inlet pipe 1; each branch water pipe 2 is equipped with a flow regulating device.

[0019] A diverter 3 is provided at the connection between the main water inlet pipe 1 and the branch water pipe 2;

[0020] The diverter 3 is equipped with a filter assembly, which includes a filter chamber 4 and a filter screen 5. The filter chamber 4 is fixedly installed inside the diverter 3. The inlet of the diverter 3 is connected to the filter chamber 4. The filter screen 5 is installed inside the filter chamber 4. A collection tank 6 is provided at the bottom of the filter chamber 4. A leakage hole 7 is provided between the filter chamber 4 and the collection tank 6. A waste discharge port 8 is provided at the bottom of the collection tank 6. A gate 9 is provided at the position of the waste discharge port 8. Limiting grooves 10 are provided on both sides of the gate 9 to cooperate with the gate 9.

[0021] The flow regulation device includes a regulating valve 11 and a flow sensor 12. The regulating valve 11 is electrically connected to the flow sensor 12. The flow sensor is used to detect the water flow rate in the branch water pipe and transmit the signal to the regulating valve. The regulating valve adjusts its opening degree according to the received signal to control the water flow rate.

[0022] The branch water pipe 2 is also equipped with a pressure regulating device, which includes a pressure pump 13 and a pressure sensor 14. The pressure pump 13 is electrically connected to the pressure sensor 14. The pressure regulating device is used to regulate the water pressure in the branch water pipe to ensure that the water flow pressure in each branch water pipe is uniform.

[0023] The diverter 3 has a conical structure. Its small end is connected to the main water inlet pipe 1, and its large end has multiple outlets 15 evenly distributed. Each outlet 15 is connected to a branch water pipe 2. The diverter evenly distributes the water flow from the main water inlet pipe to each branch water pipe.

[0024] It also includes a central controller, which is electrically connected to the flow regulating device and the pressure regulating device. The central controller is used to receive signals from the flow sensor and the pressure sensor, and to control the operation of the regulating valve and the pressure pump.

[0025] A flow equalizer 16 is installed at the end of the branch water pipe 2. The flow equalizer 16 is a perforated plate structure with multiple micropores. The flow equalizer 16 is fitted inside the cylindrical protective shell 17. A rubber sealing ring 18 is provided at the contact position between the flow equalizer 16 and the cylindrical protective shell 17. The purpose is to ensure that the water flow velocity and flow rate at the end of the branch water pipe are consistent with those at the front end. During water transport, the water flow velocity may slow down and the flow rate may decrease at the end of the branch water pipe, affecting the irrigation effect in the terminal area. The flow equalizer adopts a perforated plate structure with multiple micropores. The size and distribution of these micropores are precisely calculated and designed based on the actual water flow in the branch water pipe. Through the regulating effect of these micropores on the water flow, the water flow velocity and flow rate at the end of the branch water pipe can be effectively improved, ensuring the uniformity of irrigation along the entire branch water pipe.

[0026] Working Principle: Irrigation water enters from the main inlet pipe and reaches the distributor. The distributor has a conical structure, with the small end connected to the main inlet pipe and multiple outlets evenly distributed at the large end. This structure allows the water flow to be more evenly distributed to each branch pipe during distribution, reducing water flow impact and energy loss, and achieving initial water flow distribution. The filter components inside the distributor filter the water flow. Water enters the filter chamber from the distributor's inlet, where the filter screen intercepts sediment, impurities, and other contaminants. The filtered water continues to flow to the branch pipes. The intercepted impurities fall into the collection tank through the drain holes at the bottom of the filter chamber and can be periodically discharged through the waste outlet.

[0027] A flow sensor monitors the water flow rate in the branch pipes in real time and transmits the signal to the central controller. The central controller controls the opening of the regulating valve according to the preset flow rate value, thereby precisely regulating the water flow rate in the branch pipes to meet the water requirements of wheat at different growth stages and in different plots.

[0028] Pressure sensors monitor the pressure in the branch water pipes in real time, and the central controller controls the operation of the pressure pump based on the feedback information from the pressure sensors. When the pressure is insufficient, the pressure pump increases the pressure; when the pressure is too high, the pressure pump stops or reduces its power to maintain a stable and appropriate pressure in the branch water pipes, ensuring irrigation effectiveness.

[0029] A flow equalizer is installed at the end of the branch water pipe. The flow equalizer is a porous plate structure with multiple tiny pores, which can further disperse the water flow evenly as it passes through, ensuring that all areas of the wheat field receive uniform irrigation water.

[0030] In summary, this utility model, through the internal filtration components of the diverter, including a filter chamber and a filter screen, can filter the water flowing into the branch water pipes, intercepting sediment, impurities, etc., preventing them from clogging pipes and nozzles, and extending the service life of the irrigation system. Impurities are intercepted in the filter chamber and fall into the collection tank through the drain hole at the bottom of the filter chamber, and can be discharged periodically through the waste outlet for easy cleaning. The regulating valve and flow sensor in the flow regulation device are electrically connected. The flow sensor monitors the water flow in real time and transmits the signal to the central controller. The central controller controls the regulating valve to operate according to the preset value, precisely regulating the water flow in the branch water pipes to meet the water requirements of different wheat growth stages and different plots. The pressure pump and pressure sensor in the pressure regulation device are electrically connected. The pressure sensor monitors the pressure in the water pipes in real time. The central controller controls the pressure pump to operate based on the feedback information from the pressure sensor, maintaining a stable and appropriate pressure in the branch water pipes to ensure irrigation effect.
