Preferably, the first water inlet pipes 2 are spaced by 0.5 m.

Preferably, the peripheral wall 1 and the enclosing wall 4 are both 0.25 m higher than the field ground 5.

The working principle is as follows:

when the water level of the field ground 5 is lowered, the water inlet valve 7 senses that the water level is lowered, the water inlet valve 7 opens the valve installed on the second water inlet pipe 3, water in the tap water pipe or the water tank enters the ditch 6 through the second water inlet pipe 3, and the water enters the field ground 5 through the first water inlet pipe 2 through the ditch 6. When the water level reaches a certain height, the water inlet valve 7 closes the valve arranged on the second water inlet pipe 3, and the water supply is stopped. When the water level exceeds the closing height of the water inlet valve 7 to reach the height of the water outlet pipe 8, the water is discharged from the water outlet pipe 8 to prevent excessive rainwater. By the above measures, the water level of the paddy field is kept at a proper position.

The water inlet valve 7 may be a solenoid valve and used in conjunction with a level sensor placed in a fixed position within the trench 6, the level sensor controlling the water inlet valve 7 to open when the water level is low and controlling the water inlet valve 7 to close when the water level is high.

The inlet valve 7 may be a mechanical valve. As shown in FIG. 3, when the water level is low, the float ball 70 floats on the water surface 10. At this time, the valve core 72 is in an open state, and the water in the water inlet pipe 9 enters the ditch 6 through the ball valve 72 and the second water inlet pipe 3. As the water level gradually rises, the float ball 70 gradually rises, the rack 76 rises, and the gear 75 and the valve rod 74 are driven to rotate, and the valve core 73 is driven to be gradually closed. As shown in fig. 4, when the water level reaches the proper position, the valve spool 73 is completely closed, and the valve spool 73 is rotated 90 degrees relative to the position of the valve spool 73 in fig. 3. Similarly, as the water level decreases, the valve spool 73 gradually moves from the closed position to the open position. Thereby realizing real-time water level maintenance. The inlet pipe 9 may be a pipe communicating with a water tank or a tap water pipe.

The present invention has been described above by way of example, but the present invention is not limited to the above-mentioned embodiments, and any modification or variation based on the present invention is within the scope of the present invention.
