ABSTRACT:
The arrangement enables power generation on both ebb and flow tides, and is characterized in that one or more turbines (8) is used of a type designed for unidirectional flow, in that the or each turbine is mounted in a wall (7) which divides an enclosed space into a first area (4a) which can be brought into communication with the tidal water source (3) and a second area which can be brought into communication with a basin (2) separated from said source, and in that adjustable sluices (9a, 9b, 10a, 10b) are associated with each area and arranged so that, irrespective of the tide direction, the sluices can be adjusted to cause water to flow only in said uni-direction through the turbine.
The enclosed space may be provided by a walled enclosure which includes a part (1a) of the length of a barrage wall (1) extending across the water source.
Preferably the walled enclosure is rectangular comprising two side walls (5) and a rear wall (6) and the wall (7) in which the turbine (8) is mounted extends from said part length (1a) of the barrage wall to said rear wall.
In a development of the invention, the turbine wall (7) is extended to divide the basin into two subbasins (2a, 2b) to enable prolonged power generation to occur and economy in turbine numbers to be made by double use of them.
