The invention discloses a double-turnover gate structure. A gate is arranged between a water inlet of a storage tank and a water inlet pipe orifice of a drain pipeline, and is matched and sealed with the water inlet pipe orifice of the drain pipeline when the water level of a river exceeds a water outlet pipe orifice of the drain pipeline, or is matched and sealed with the water inlet of the storage tank when rainwater flows over a weir plate in a later period; a hydraulic oil cylinder is further arranged between the water inlet pipe orifice of the drain pipeline and the water inlet of the storage tank; a piston rod of the hydraulic oil cylinder is hinged to the gate. According to the double-turnover gate structure, a turnover gate structure can be used for sealing a flow passage which is bilaterally opened and closed to realize unilateral flow passage opening and closing to control a water flow path to control the drainage of rainwater and simultaneously prevent flood backflush; the double-turnover gate structure is simple in structure, small in size, easy to mount and operate, low in cost and high in working stability, and has high practicability and market application value.
