Flexible and convenient water conservancy building device

The invention discloses a flexible and convenient water conservancy building device. The flexible and convenient water conservancy building device structurally comprises a gate frame groove, a coil wheel disc gate plate, a pushing screw rod, a shell frame groove and a hand dragging wheel disc seat. According to the flexible and convenient water conservancy building device, the coil wheel disc gate plate is matched with the pushing screw rod, the adjusting and controlling operation effect that screw blade pipes are twisted to be matched with the screw rod to ascend and descend is formed at the two ends of a rotor fan plate disc, the subsequent screw blade pipes on the two sides obtain the pad brush dredging fluid spiral sedimentation operation effect, the flood discharge surging amount during gate opening of a gate truss hanging plate is reduced, the impact force of the water flow downward discharge amount is reduced, and therefore the overall water conservancy building maintenance degree and the timely gate o
