  • Patent number: 10731622
    Abstract: Device for converting mechanical energy from sea waves into electric energy including at least a float and two rigid rods. The rods are preferably anchored to the seabed at one end, and to the float at another end. There are also two ballasts that effect their weight towards the sea bed to keep the free ends of the rods constantly in traction and free to rotate around their hinges. The float oscillates up and down along a vertical line due to waves. There are at least two cables that connect the free ends of the rods to a transmission shaft of a generator positioned along the vertical line so that the vertical, horizontal, or rotary oscillatory motion of the float caused by the waves generates an oscillatory motion of the rods which are pivoted on their respective hinges, and thus transfers rotary motion to the transmission shaft of the generator.

  • Patent number: 9062649
    Abstract: Device (100) for conversion of mechanical energy from sea waves to electric energy, characterized by:—at least a float (101) and two rigid rods (102), (103), preferably anchored at one end to the seabed (108), and at the other end to the float (101) through flexible cables (106), (107); two respective masses (104), (105) keep the free ends of that rods (102), (103), constantly in traction condition pulled towards the sea bed (108);—at least a power generator (109), or other similar device suitable to convert and/or transmit energy, that is placed close to its respective hinge (110), (111), placed at the bottom parts of the rods (102), (103), so that the oscillatory motion of the float (101), following the waves level (112), causes a force with a vertical component that leads to a rotatory and oscillatory motion of the rods (102), (103), which are pivoted on its respective hinge (110), (111), and generates therefore electric energy by motion of gears of the same generator (109); the horizontal component of the
