PONTOON TIDAL POWER PLANT Russian patent published in 2012 - IPC F03B13/12 

FIELD: electricity.

SUBSTANCE: pontoon tidal power plant comprises pontoon vertical cylindrical shells (1), generators, water intake and discharge pipes (20), a system of ropes (8) and anchors (9). Shells (1) are installed with a gap between adjacent shells along a longitudinal line, perpendicular to direction of tide (4). In the middle part of pontoon shells (1) at both sides there are ropes (8) fixed as connected to anchors (9). In the pontoon vertical cylindrical shell (1) there is a water-receiving (10) and dry (11) chambers concentrically arranged. The water-receiving chamber (10) is divided by a partition (12) into sections. In each section there are outlet nozzles (13), a perforated flow distributor (14), a central perforated riser (16), an inlet nozzle (19) of a discharge pipe (20). Outlet nozzles (13) are installed tangentially for flow swirling. The flow distributor (14) is made as a truncated cone with an open upper base and a lower base (15) closed by a wall. The perforated riser (16) is made in the form of a pipe. The lower hole (17) of the pipe is opened, and the upper one is connected to a fish-discharge pipe (18). A dotted line (26) shows position of the pontoon vertical cylindrical shell (1) at the maximum level of water in the sea.

EFFECT: exclusion of fish passage via working elements of generators provides for higher efficiency of fish protection.
