Active water storage irrigation device for hydraulic engineering

The invention discloses an active water storage irrigation device for a water conservancy project, and relates to the technical field of water conservancy water storage. The device comprises a storage tank, a filter screen plate is arranged in the storage tank, a rotating shaft is arranged below the filter screen plate, a water wheel is fixedly mounted on the rotating shaft, a cam is fixedly mounted on the rotating shaft, a water storage irrigation mechanism is arranged on the outer side of the storage tank, and the water storage irrigation mechanism comprises a water suction pipe arranged on the outer side of the storage tank; a water outlet nozzle is fixedly mounted at one end of the water suction pipe, and the other end of the water suction pipe is arranged in the ground suction pump. The gravity effect is generated when liquid water descends, so that a rotating shaft drives a cam to rotate, then a filter screen plate can be driven to vibrate up and down, filtered impurities move in the inclination directi
