This invention relates to the field of emergency repair technology for piping in dams, and discloses a flood control device for rapidly sealing piping in dams. The device includes a filter screen and a rubber plate positioned at opposite ends. Both screens have thickened sides forming a "U"-shaped rubber section with an internal support frame, which, together with the rubber frame, forms a chamber with an open top. The chamber is filled with a reverse-filtration counterweight medium. When high-pressure water impacts the rubber plate, fine particles enter the chamber, forming a dynamically graded sedimentation layer to release water pressure and prevent erosion of the dam foundation. The core of the device lies in the support frame being configured as a self-locking linkage mechanism based on mechanical feedback. When external water pressure pushes the rubber plate to cause a lateral overturning tendency, the support frame can mechanically force the bottom plate to press against the dam ground, increasing the positive pressure and frictional resistance between the device and the ground, and combining this with the passive resistance of the fixed frame to balance the overturning moment. This invention can quickly respond to emergencies, resist water flow impact, adapt to complex terrain, and achieve reliable reverse-filtration sealing.
