This invention discloses a high-sealing, flip-type flood-proof baffle structure, comprising a base plate installed inside the ground, with two walls symmetrically arranged on both sides of the top surface of the base plate, and a flip-type baffle positioned between the two walls. This invention utilizes the impact of accumulated water to cause the flip-type baffle to rotate synchronously with the sealing element via a G-shaped groove during the flipping process. The U-shaped part of the sealing element moves on the surface of the decorative panel, while always maintaining contact with the decorative panel. The U-shaped part expands and deforms under compression, achieving a waterproof seal between the flip-type baffle and the decorative panel throughout the flipping process.
