Flood control structure capable of being folded in self-adaptive mode

The invention discloses a flood control structure capable of being folded in a self-adaptive mode. The flood control structure comprises a movable block unit, a fixed support and a fixed unit, and the movable block unit can be switched between at least two states. The structure form and the structure height can be spontaneously changed under the impact of water flow, additional internal power is not needed, and the structure is driven to be rapidly in place to different heights only by means of self-adaptive change of hinges between the units so as to regulate and control the water level or adjust the flow overflowing through the device, so that the upstream water level is kept within a certain value, and the water level is kept within a certain range. Therefore, the purpose of flood control is achieved, and a new thought is provided for flood disaster prevention. According to the flood control structure capable of being folded in a self-adaptive mode, overall building and disassembling of the flood control s
