The invention discloses a hydro-automatic flap gate. The hydro-automatic flap gate comprises a pier and an outrigger, wherein the pier is arranged at the storage dam weir crest and provided with an arc-shaped wheel, and the outrigger is connected with the pier movably and provided with a slide groove connected with the arc-shaped wheel. The hydro-automatic flap gate is further provided with a limiting connection rod and a large connection rod, wherein two ends of the limiting connection rod are hinged to the arc-shaped wheel and the outrigger respectively, a limiting groove is formed in one end, close to the outrigger, of the limiting connection rod, one end of the large connection rod is hinged to the pier, and the other end of the large connection rod is connected in the limiting groove slidably. The hydro-automatic flap gate has the advantages that the problem of outrigger cement cracking caused by the fact that a guide plate is excessively narrow to result in excessive concentration of stress points during long-term use is solved; the problem that the hydro-automatic flap gate is blocked by impurities in a riverway is eradicated completely, so that safety of the hydro-automatic flap gate in use is ensured; the hydro-automatic flap gate is simple to manufacture, symmetrical in structure, convenient to mount and lower in cleaning cost and maintenance cost.
