[0046] S3. During drainage, the cylinder 24 in the switch 8 is energized to extend the telescopic end of the cylinder 24 and drive the blocking plate 23 to move and block the internal channel of the irrigation component. At this time, the interior of the drainage component is in an unobstructed state, and the sliding frame 5 is controlled by the walking mechanism to move back and forth on the track frame 1. The water pump 10 is started to pump water through the suction pipe 14 as the sliding frame 5 moves. At the same time, the pumped water is discharged into the drainage circular pipe 4 through the drainage pipe 12, and flows into the recovery pipe 13 due to the slope in the drainage circular pipe 4. The water is recovered and stored through the recovery pipe 13 for subsequent irrigation use, thereby achieving the purpose of water-saving irrigation.

[0048] By setting up the water level sensor, the amount of water in the paddy field can be detected through its sensing end, and the standard range data of the current amount of water in the paddy field can be input into the database module through conventional technical operations in the prior art. The data processor can compare with the database module to determine whether it is irrigation processing, drainage processing or no response, and automatically select to control irrigation or drainage, so that the water-saving irrigation and drainage device can be used intelligently. Specifically, when the water level sensor detects that the amount of water in the paddy field is less than the standard range data of the current amount of water in the paddy field, the irrigation component will be started to spray water; when the water level sensor detects that the amount of water in the paddy field is greater than the standard range data of the current amount of water in the paddy field, the drainage component will be started to pump water, and when the water level sensor detects that the amount of water in the paddy field is within the standard range data of the current amount of water in the paddy field, no response will be given;

[0049] During irrigation, the water inlet short pipe 9 in the irrigation assembly is placed into the water source by connecting the external connecting pipe in the conventional operation of the prior art, and the water is pumped into the short pipe 7 through the water inlet short pipe 9 by starting the water pump 10, and sprayed out from the water spray hole of the nozzle pipe 6, and the walking mechanism is started at the same time, so that the slide frame 5 moves back and forth on the rail frame 1 and sprays water to irrigate the rice field. Through this operation, the irrigation water per unit area of ​​the rice field can be more uniform, avoiding the situation of over-irrigation in some areas; during drainage, the air in the switch 8 is switched on. The cylinder 24 is energized to extend the telescopic end of the cylinder 24 and drive the blocking plate 23 to move and block the internal channel of the irrigation component. At this time, the interior of the drainage component is in an unobstructed state. The sliding frame 5 is controlled by the walking mechanism to move back and forth on the track frame 1. The water pump 10 is started to pump water through the suction pipe 14 as the sliding frame 5 moves. At the same time, the pumped water is discharged into the drainage circular pipe 4 through the drainage pipe 12, and flows into the recovery pipe 13 due to the slope in the drainage circular pipe 4.
