Layered water intake, but the use of stacked beam doors to achieve layered water intake, the operation is cumbersome, the management is complicated, the sealing between the stacked beam doors is poor, and there is leakage. Equipped with telescopic sliding device to realize the automatic operation of the water inlet with the water level.
