Abstract
A sea wave power plant for generating electricity, and for supplying high pressure fluids to a water purification system. The power plant includes two compartments adjustable differential hydro cylinders that are assembled on floaters, an axial piston variable motor, a system for protecting the floaters in periods of storm in a way that the floater are positioned horizontally outside the water, and an automation sub-system. The wave power plant is combined of several modular units that each one of them serves as independent sea water power plan.
Claims5
A sea wave power plant that comprises a floater (1), a hydro cylinder (3), an accumulator (17), a hydro motor (22), a generator (24) that is associated with the hydro cylinder (3), and an automation system (34);
- wherein the hydro cylinder (3) includes a main chamber (62) and a secondary chamber (61) that are separated by a piston (701) that is connected to a piston rod (700), wherein the hydro cylinder (3) is designed to compress oil from the main chamber (62) to the accumulator (17);
- wherein the main chamber (62) is designed to contain oil and is further designed to be connected to a high pressure line (12) by a first valve (64) and to a hydraulic tank (28) by a second valve (63),
- wherein when the floater (1) rises upwards the piston rod (700) is designed to be pushed inwards and to reduce a volume of the main chamber (62) so that the oil from the main chamber (62) can flow to the high pressure line (12) through the first valve (64);
- wherein the main chamber (62) and the secondary chamber (61) are connected by a selector (70) that is capable to enable the oil in the main chamber to flow from the main chamber (62) to the secondary chamber (61) when the piston rod (700) is pushed inwards, so that the volume of oil that flows into the high pressure line (12) is equal to a volume of the part of the piston rod (700) that penetrates inside the secondary chamber (61).
