[0035] The implementation principle of the water-saving irrigation device for high-standard farmland construction in the embodiment of the application is as follows:

[0036] The irrigation water tank 11 as the main storage unit of the water source is located at the top of the frame 15, fixed by screws, and designed to store enough water to meet the irrigation needs. The water pump 12 is located at the top of the irrigation water tank 11, fixed by bolts, which is responsible for pumping water from the irrigation water tank 11 and sending it to the drain pipe 13 through the water inlet pipe 14. The total water delivery pipe 21 is responsible for delivering water from the irrigation water tank 11 to each irrigation point. It is located at the bottom of one side of the frame 15, with its outer wall connected to the top of the irrigation water tank 11 by bolts. Two three-way pipes 22 are symmetrically arranged and connected to the branch water pipes 23 through flanges. This pipeline constitutes a secondary network for distributing water flow from the total water delivery pipe 21 to the irrigation area.

The adjacent ends of the two L-shaped water pipes 24 are installed with an arc-shaped water pipe 26 through a rotary joint. The design of the arc-shaped water pipe 26 and the use of the rotary joint make the pipeline adaptable to different irrigation area layouts and sealed rotation. A plurality of U-shaped long pipes 27 and U-shaped short pipes 28 are staggered on the outer wall of the arc-shaped water pipe 26. This pipeline is the part that directly performs irrigation, allowing the water flow to evenly cover the irrigation area. The outer wall of the L-shaped water pipe 24 is connected to a motor seat 31 through bolts, and a servo motor 32 is connected to the top of the motor seat 31 through screws. The servo motor 32 is connected to the main gear 34 through the output shaft. The main gear 34 is designed to transmit the rotational power of the servo motor 32 to the secondary gear 33. Through this gear transmission mechanism, the rotation of the servo motor 32 can control the rotation of the secondary gear 33, thereby controlling the rotation of the secondary gear 33. The rotation of the arc-shaped water pipe 26 is driven by the secondary gear 33, which directly affects the specific irrigation position of the multiple U-shaped long pipes 27 and U-shaped short pipes 28.

The support 45 is arranged in an inclined manner.And through the drive shaft 43 and stepper motor 42 connection, so that the direction of the water can be adjusted according to the needs of multi-angle, the bottom of the cross rod 44 is connected with the cylinder 46, through the expansion and contraction of the cylinder 46, the height of the connecting pipe 47 can be adjusted, so as to change the coverage area of the water spray, the inside of the water spray cover 48 is installed with the cross spray pipe 49 connected with the connecting pipe 47, forming the final output part of the irrigation system, the outside wall of the cross spray pipe 49 is provided with a plurality of spray holes to realize the uniform distribution and accurate control of water flow, by adjusting the size and distribution of the spray hole, the spray intensity and range of water flow are accurately controlled, so as to ensure the uniformity and efficiency of irrigation, in general, the water irrigation device in this section realizes efficient use and accurate distribution of water resources through control of mechanical structure, not only improves the irrigation efficiency of farmland, but also significantly reduces the waste of water resources, at the same time, ensures that crops can get uniform and sufficient water supply, helps to improve the yield and quality of crops, the two groups of electromagnetic valves two 29 on the U-shaped long pipe 27 and the U-shaped short pipe 28 are controlled independently, the independent control mechanism makes the two kinds of pipes can be operated independently according to the specific irrigation demand, flexibly selects different water outlet modes to adapt to the irrigation demand of different crops and soil conditions, the U-shaped long pipe 27 and the U-shaped short pipe 28 enable the irrigation system to irrigate in a large range or for specific areas, which can realize extensive spraying and more concentrated and accurate drip irrigation, which is crucial for saving water resources, improving irrigation efficiency and ensuring that crops receive appropriate amount of water uniformly.

[0037] The water irrigation device in this section can include but not limited to the following different irrigation modes to adapt to the needs of different crops and soil conditions:
