Rotary movable anti-flood wall

The invention discloses a rotary movable anti-flood wall which is arranged on an opening section of a standard anti-flood wall on the top of a dike pond and comprises a gate, an embedded part, a hoist and a hoist chamber. A foundation pit is formed in the upstream side of the top of the embankment pond, the hoist is located in the hoist chamber, and the hoist chamber is located on one side or two sides of the gate and closely connected with the standard anti-flood wall on the corresponding side; the hoist is connected with a bottom shaft of the gate through a coupler, and the hoist outputs large torque to drive the bottom shaft of the gate to rotate; the gate can rotate around a supporting hinge fixed to the foundation pit, the gate rotates upwards and stands up to form a water retaining structure, and the gate is laid down to cover the foundation pit to form a dike top road. The system is linearly arranged, is compact in structure and small in occupied area, does not have any structure on the exposed ground,
