Claim:
An anti-flooding device with displacement of the waters for the exploitation of the water energy, comprising: a pipeline having an upper opening ( 2 ) in an upper part of the pipeline and a lower opening ( 6 ) in a bottom of the pipeline, the upper opening for allowing an inflow of fluid from above the upper opening, the lower opening for allowing an outflow of the fluid via the lower opening; an extractable filtering net ( 5 ) for filtering the inflow of the fluid entering from the upper opening; a sluice-gate ( 3 ) that closes the lower opening ( 6 ), the sluice-gate having a section of one of a truncated cone and a cylinder; sealing gaskets for sealing the sluice-gate; a cable ( 4 ); a float ( 1 ) connected to the sluice-gate ( 3 ) by the cable ( 4 ) so that a rising operation of the float i) allows the inflow of the fluid into the pipeline via the upper opening ( 2 ) and ii) moves the sluice-gate to open the lower opening; an air pipe ( 11 ) having a first opening located above the upper opening ( 2 ) and a second opening located below the upper opening ( 2 ), the float sliding on the air pipe; a pipe ( 8 ) connected to the lower opening ( 6 ) and arranged to receive the outflow of the fluid; a plurality of valves ( 9 ) connected to the pipe ( 8 ) for closing the pipe ( 8 ) and preventing flow of the fluid; a plurality of rings ( 10 ) for fixing and sliding of the float ( 1 ); and a lever ( 12 ) for the manual rising of the float ( 1 ).
