[0033] The working principle and use process of the present invention are as follows: when using this device, the staff first stores water in the irrigation canal and always keeps the water level of the canal 40 cm to 50 cm higher than the rice field. Then the staff moves the carrying handle 6 to carry the irrigation device to the rice field, and installs and fixes the irrigation device through the base plate 10, the fixing hole 13 and the supporting leg 14. Then, according to the irrigation water level requirement of the rice field, the adjusting bolt 20 is loosened to loosen the adjusting rod 3, and the float 15 is adjusted to the appropriate water level. Tighten the adjusting bolt 20 to adjust the float 15, complete the artificial setting of the water level, then connect the connecting soft water pipe in the canal with the connecting water head 9, use the height difference of the water level in the canal to inject the irrigation water into the water storage tank 12 through the water inlet pipe 29, and then continuously inject the water into the irrigation water tank 24 through the water delivery pipe 25. When a certain amount of water is stored in the irrigation water tank 24, the internal water pressure squeezes the water delivery pipe 25, the blocking plate 36 and the water stop rubber pad 23 downward, releasing the blocking plate 36. 6 and the sealing state of the water outlet 40 by the water-stop rubber pad 23, the irrigation water flows out and flows out through the U-shaped irrigation device 37 to automatically irrigate the rice field. When the water in the rice field exceeds the set water level, the float 15 senses that the water level is one centimeter lower than the artificially set value. The float 15 moves downward to make the upper and lower floating switch valve head 28 block the drain pipe 27 and close the drain outlet of the irrigation water tank 24. At this time, the irrigation water tank 24 continues to store water. When the water level rises to a certain level, the water pressure gravity pushes the water pipe 25 again. And the blocking plate 36 moves downward to release the blocking state of the water outlet 40 again, and the rice field is irrigated again. When the water level in the field rises to the set value, the float 15 senses and causes the upper and lower floating switch valve heads 28 to float up and open the drain pipe 27. At this time (the drainage is greater than the inlet water), the water in the irrigation water tank 24 is discharged, and the water pressure in the canal pushes the blocking plate 36 and the water-stopping rubber pad 23 to rise and close the water outlet to stop irrigation, thereby realizing artificial water level setting and fine-tuning the automatic irrigation facility of one centimeter to realize the positioning automatic irrigation of the rice field.
