Ocean power turbine

An ocean power turbine for converting a slow water flow energy comprising

• two endless rotation chains having a plurality of plate holders arranged in said two endless rotation chains, each of said plurality of plate holders comprising at least one plate attached therein,
• wherein:
• each endless rotation chain runs in an extended path around and engages with at least one drive wheel in one end arch of said extended path via at least one engagement device comprising at least one pair of upper and lower coupling pins,
• each of said at least one plate is pivotably attached to a corresponding one of said plurality of plate holders to switch between an open position with a primary flow direction of water flow and a closed position towards said primary flow direction,
• said at least one drive wheel has a turbine shaft coupled to a generator device for utilizing a rotational energy,
• said extended path of each endless rotation chain is slanted relative to said primary flow direction of the water flow, arranged in a fully or partially submersible support structure,
• the two endless rotation chains comprising said plurality of plate holders are oppositely arranged in a plow formation,
• said fully or partially submersible support structure comprises a partition wall arranged along said extended path of a web inside said extended path of said each endless rotation chain in a full height of said at least one plate,
• said fully or partially submersible support structure is sub divided into a top section and a bottom section respectively above and below an operating structure, outer walls of said top section comprise at least a sloping lower wall portion towards the operating structure, and outer walls of said bottom section comprise at least a sloping upper wall portion towards the operating structure,
• said at least a sloping lower wall portion, said at least a sloping upper wall portion and together with the partition wall form a lateral concave duct for guiding water towards said at least one plate and increase water current in a slow water flow and thus power to said at least one plate and further power to said ocean power turbine, and
• wherein each of said plurality of plate holders has a circular frame structure in a vertical direction of said circular frame structure and holds the at least one plate, each of the at least one plate being a half circle and accommodated within the circular frame structure provided with a full diameter in the vertical direction and laterally pivotally attached to the circular frame structure in at least an upper and lower position of the at least one plate and with a stop device for a full open co-current position.
