FIELD: turbines or turbomachines.
SUBSTANCE: invention relates to device for wave energy extraction. Device comprises floating platform (2), cylinder (1) and piston (5) with rod (6) connected to mooring element (10). At least one pressure pipe is in fluid communication at its lower end with lower section of cylinder (1) under piston (5). At least one pressure pipe is provided along cylinder (1) and has a hole on the upper end facing water turbine (4) located above cylinder (1). Turbine (4) is connected to generator (15). Cylinder (1) has at least one hole in lower section and is provided with one-way valve (22) made with possibility of water passage into lower section of cylinder (1). Cylinder (1) has at least one hole in upper cylinder section made with possibility of water passage into upper section of cylinder (1). Upper hole of at least one pressure pipe additionally contains one or more adjustable nozzles made with possibility to adjust pressure and speed of water leaving at least one pressure pipe.
EFFECT: invention is aimed at creation of effective and powerful device for wave energy extraction.
