A water gate for drawing water from farmland
The present invention belongs to the technical field of sluices, and discloses a sluice for drawing water from farmland, including a concrete slab. The present invention cooperates with structures such as a foundation and a concrete slab, and according to the water pressure difference, the water on the side of the foundation always flows and pushes the water into the first water trough. The water inside the gate trough will always spray upward and be carried away by the water flowing above the foundation. The water pressure on the gate trough will prevent garbage from entering. The notch on the sealing block is connected to the second water trough. Water needs to overcome gravity to enter the gate trough upward and will also lose potential energy when it hits the bend of the first water trough. It will flow directly away through the second water trough. The suction force at the end of the first water trough increases and extracts a portion of silt, reducing the possibility of the end of the first water trough being blocked.
