The invention belongs to the technical field of hydraulic gates, and discloses a flood prevention gate for hydraulic engineering and an operating method thereof. The flood prevention gate comprises a gate body, wherein four drainage holes are formed in the bottom of the gate body, valve plates are arranged on the inner sides of the drainage holes, inserting buckles are arranged at the bottoms of the valve plates, and a hydraulic rod, a rack and a gear are embedded in a dam body below the gate body. According to the flood prevention gate, when the gate body is closed, the valve plates are kept to be normally open to the maximum extent, when water flow impacts the gate body in the front face, the part, which flows to the drainage holes, of the water flow can flow away along the opening space of the valve plates, and the water flow cannot directly impact the gate body in the front face, so that the impact area borne by the gate body is reduced, the impact force of the water flow is reduced, the working load borne by a corresponding opening and closing device is correspondingly reduced, sleeve buckles are started to drive the valve plates to rotate during small-flow drainage, the valve plates are opened for small-flow flood discharge, and the high-power opening frequency of the gate body is reduced.
本发明属于水利闸门技术领域，且公开了一种水利工程用防汛闸门及其操作方法，包括闸门本体，所述闸门本体的底部开设有四个排水孔，所述排水孔的内侧设有阀板且阀板的底部设有插扣，所述闸门本体下方的坝体埋设有液压杆、齿条和齿轮。本发明通过令闸门本体在关闭时保持阀板最大常开，水流对闸门本体正面冲击时，流到排水孔的部分会顺着阀板开启的空间流走，而不会直接对闸门本体造成正面冲击，从而减小了闸门本体所受到的冲击面积，减小了水流的冲击力，相应的起闭装置所受到的工作负荷也会相应的减小，小流量排水时，启动套扣带动阀板转动，将阀板开启进行小流量泄洪即可，减少闸门本体的大功率开启频次。
