The diversion structure includes a diversion plate 12, a second sealing plate 13 and a push cylinder 14. The diversion plate 12 is fixedly connected to the column 10. The same side of the two columns 10 are rotatably connected to the same second sealing plate 13. The second sealing plate 13 is pushed and turned over by the push cylinder 14 to form a funnel-shaped guide channel. The push cylinder 14 includes a cylinder and a push rod part. The push rod is slidably connected to the cylinder, the cylinder is rotatably connected to the diversion plate 12, and the push rod is rotatably connected to the second sealing plate 13. In this solution, the first sealing plate 11 is limited by the two columns 10. The first sealing plate 11 needs to be used in conjunction with a winch. The first sealing plate 11 is lifted by the winch. The sealing plate 11 is hoisted, and two columns 10 are installed on both sides of the inner wall of the irrigation ditch. The first sealing plate 11 rises, so that water flows between the two columns 10. By energizing the push cylinder 14, the push cylinder 14 pushes the corresponding second sealing plate 13 to flip, and the two second sealing plates 13 are distributed in an inward-facing shape, and then the two second sealing plates 13 form a funnel-shaped channel with a gradually narrowing opening to guide the water discharged from the two columns 10, so that the flow area of ​​the water is reduced, thereby realizing the acceleration and convergence of the convective water, so that when the first sealing plate 11 is opened to irrigate the field, the initial velocity of the water is greater, and it can flow along the ditch to a farther field, reducing the probability of over-irrigation of the farmland near the column 10, and ensuring uniform irrigation.
