Water conservancy flood prevention monitoring system

The invention relates to the technical field of water conservancy projects, in particular to a water conservancy flood prevention monitoring system which comprises a floating body shell, and a support is fixedly mounted at the upper end of the floating body shell. When an eccentric wheel rotates to the front side, the eccentric wheel is separated from a piston rod, at the moment, the piston rod is reset under the action of a third spring, and water absorption is stopped; an eccentric wheel is in contact with a push frame and extrudes the push frame, the push frame is forced to slide forwards on a support, the push frame drives an inclined block to slide forwards on a floating body shell, the inclined block extrudes a movable rod, so that the movable rod moves downwards on the floating body shell, a spring IV is compressed, the movable rod drives a filter plate to move downwards, and the filter plate is separated from a liquid inlet pipe; when the eccentric wheel rotates and is separated from the push frame, t
