WO2005103485A1 – Reciprocating Generator Wave Power Buoy – Google Patents

Electric current flowing through the generator coil 16 creates an induced force on the generator coil 16. The damping plates 18 attached to the coil extending out into the still water inhibit the movement of the coil caused by the induced force, thereby keeping the coil 16 stationary in relation to the movement of the magnetic housing. The relative motion of the magnetic field through the generator coil 16 creates an electro-motive force (emf) in the coil. In addition, an electromagnetic winding mounted behind each permanent magnet receives a small portion of the electric energy generated by the relative motion between the magnetic core and the bobbin coil. Each of these systems suffer from losses of efficiency in the process of converting wave motion into movement of a fluid and in turn uses the fluid motion to turn a turbine that turns a rotating generator. These systems lose more efficiency during the step of converting the linear fluid motion into rotating turbine motion that drives the generator.

A reciprocating piston inside the tube pumps water up the tube to turn a turbine that turns a rotating generator. The air motion in the shaft then turns the turbine that drives the electric generator. Prior art wave generating systems also use wave motion to drive a hydraulic pump to force a fluid through a turbine connected to an electric generator.

One such prior art system uses wave motion to force air through hollow shafts and uses a by- directional turbine placed in the air shaft to produce electric power. The reciprocating generator power buoy of the present invention uses a linear generator that directly converts the vertical motion of ocean swells into electric power. The reciprocating electric generator 11 for use in an oscillating fluid, as shown in Figures 4 and 5, has a magnetic core having a magnetic center pole 32 and radially configured outer poles 31 to form an elongated bore extending thereinto and capped on both ends with end caps 33. The magnetic core is adapted to be submerged in an oscillating fluid, such as ocean water. BACKGROUND OF THE INVENTION The present invention relates to an electrical generator and especially to a reciprocating generator attached to the underside of an ocean buoy that produces electric power responsive to movement of the buoy riding on an oscillating fluid.

Damping plates attached to the generator coil maintain the coil in a stable position as the generator’ s magnetic housing, solidly connected to the underside of an ocean buoy, reciprocates up and down with the passing ocean swells. The buoy member 13 floats on the surface of an oscillated fluid while the rigid structure 14, rigidly attached to the underside of the buoy member, holds the magnetic core and generator coil 16 at a fixed distance beneath the buoy member 13 so that the magnetic core moves responsive to movement of the buoy on an oscillating fluid and the generator coil 16 remains in a generally steady position with respect to the moving magnetic core. The buoyancy tanks 23 are attached to the generator coil 16 such that the generator coil is suspended in the fluid at a depth below the buoy as to be in a vertical center location of the annular bore during times when oscillating fluid has no oscillations on its surface.

Neutral buoyancy tanks 23 maintain the generator coil 16 at a specific depth below the buoy 13 and in the center of the magnetic housing stroke length. Dolor muscular intercostal . The rigid connecting structure places the generator at a depth below the ocean surface not effected by the surface ocean swells. DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, Figures 1 through Figure 4 show an electric generator 11 for generating electric power from ocean swells in a body of water 12, having a magnetic core supported on the underside of a buoy 13. A rigid structure 14 connects the reciprocating electric generator 11 to the buoy 13 and is of such a length as to place the generator 11 in still water below the surface swells and wind waves.

A small portion of the electric power created in the generator coil passes through the plurality of electromagnetic windings placed in series with the plurality of permanent magnets, increasing the magnetic field and hence the power output to the generator. In Figures 4 and 5, neutral buoyancy tanks 23 can be seen mounted to the reciprocating generator coil 16 between linear bearings 22. Electromagnetic windings 37 are wrapped on the outer poles 31. A plurality of electromagnetic windings 37 are mounted in series with the permanent magnets 21 along the outside diameter of the annular bore and are electrically coupled to the generator coil 16 to thereby generate an electromagnetic field within the annular bore when the magnetic core moves relative to the generator coil and permanent magnet magnetic field to increase the magnetic field in the magnetic core.

A plurality of permanent magnets 21 are mounted in the magnetic core along the outside diameter of the annular bore. The reciprocating generator consists of a permanent magnetic core that reciprocates with respect to a stationary coil that is annularly wound on a bobbin. The damping plates 18 maintain the generator coil 16 in a stable position while the magnetic core 31, 32, & 33 reciprocates linearly in response to external forces acting on the buoy by the passing ocean swells and wind waves.

The magnetic housing reciprocates linearly in response to an external force acting on the buoy by the passing ocean swell while a rigid connecting structure holds the reciprocating generator beneath the buoy. Patent Nos. 6,140,712 and 6,226,989, a Wave Energy Converter uses a tube attached to the underside of an ocean buoy. This design increases the efficiency of converting the energy in ocean swells and waves into electric power. They convert the motion of the ocean swells into linear motion of another fluid resulting in a loss of efficiency. This linear generator eliminates the conversion steps required to turn a standard rotating generator thereby eliminating the efficiency losses incurred by other systems. The increase in the magnetic field increases the efficiency in the power output of the linear generator. SUMMARY OF THE INVENTION A Reciprocating Generator Power Buoy generates electric power from the surface ocean swells. Pluralities of permanent magnets 21 mounted in the annular bore create a uniform magnetic field so that when the magnetic core moves up and down with respect to the stationary generator coil 16, electric power production occurs within the generator coil 16. Que hacer para aliviar el dolor de rodilla . Electromagnetic windings in series with the permanent magnets 16 receive a small portion of the electric energy generated in the generator coil 16. This, in turn, generates an electromagnetic field within the magnetic core, thereby increasing the magnetic field initially created by the permanent magnets 21, and hence increases the magnetic field in the generator annular bore 17 air gap.
