An anti-flooding device with possible displacement of the waters for the
exploitation of water energy includes a double closing system with an
outer or inner cylindrical element with automatic, semi-automatic or
manual operation, a pipe-line provided with an opening at the surface
level which assures a constantly equal water level in the basin, and
below which there are a plurality of pipes which come out above the
surface for the air passage and for being guided to a float connected to
a tubular sluice-gate that closes an opening on the bottom of the main
pipe-line.
