<p>This invention relates to a device intended to harness the energy from the motion of sea waves for the generation of electric power. Said device is comprised of two identical floating bodies with a cylindrical shape (1), which will be exposed to the movement of waves. The two floating bodies are connected by means of arms (2) to a rotary axis (rotary in a plan perpendicular to the sea) (3), this being located on a rotating head (rotating m a plan parallel to the sea) (5), above the (usually predictable) reach of water, and around a mast (6) which is fixed to the sea bed. By action of sea waves, the floating cylinders, which have the buoyancy inherent to their volume and mass, will rise towards the crests and fall towards the troughs. So, an upward and downward circular movement is performed around the axis, where it will be harnessed by a hydraulic or other system (4). All the points which are susceptible of a dynamic seal will operate out of water. As a component of the system, the rotational movement of the rotating head (5) enables the floating cylinders (1) to be positioned according to the changing direction of waves propagation. The floating bodies (1) will be the selected structural element for application of the system designed to extract energy from the movement of structures without interference (7), as per the Portuguese patent PT103911. A part of the remaining structure will be used as ballast reservoirs {9} to control the movement of the floating cylinders.</p> |
