US8810056B2 – Ocean Wave Energy Converter Utilizing Dual Rotors – Google Patents

Housed in the inner cavity of the main body 12, a control system may incorporate sensor networks including pressure sensors in the buoy 24. Due to independent buoy 24 motions, an associated sensor would require wireless data transmission to buoyancy chamber controls and such radio transmission has possibly deleterious effect to marine bio-forms. This method is very costly, difficult and dangerous as it involves expensive equipment and possibly diving to depths of the ocean with all the known hazards thereof. Also because wave energy converters are generally deployed in the ocean, they must be securely anchored lest they become navigation hazards or get damaged. FIG. 6 is a method of mooring the ocean wave energy converters of the present invention to the sea floor.

Furthermore is desirable to have a less costly method of anchoring the energy converters to the sea floor that minimizes the time that divers and submersibles must be used. However, traditional mooring methods involve setting multiple lines or fixed columns to the sea floor. 6, arrays 100 generally form neutrally buoyant, horizontal planes near below the hydroface 101. Typically of breadth spanning multiple wavelengths, in most instances some array 100 portions are influenced by downward gravity forces from wave troughs while other portions are influenced by upward buoyancy force from buoys 24 and buoyancy chambers. One end of the drive rod 22 is passed through an aperture 94 on the lower 82 shell and secured to the upper shell 80. Optional bracing elements 96 are secured to around the drive rod 22 and to the lower shell 82 to reduce the strain on the lower shell 82 and drive rod 22 from the force of the waves impacting the buoy 24. Prior to deployment of the assembly, the unassembled shells 80, 82 of the buoys 24 may be stacked together for ease of storage and transportation to the deployment site.

Pressure sensors may also be included in the inner cavity of the main body member 12 and in the buoys 24 and may be used to send control data to the pump 74 and bladders 76 for adjusting the assembly attitude. The sensor data form the inner cavity data integrates with the buoy pressure data. For the purpose, buoyancy chamber pressure sensor indicates its position relative to the hydroface.

The internal braces 92 are attached the drive rod 22 and radial cuff 90. Discopatia lumbar tratamiento del dolor . Each shell 80, 82 is lined with foam or other buoyant material to neutralize the buoyancy of material forming the shells 80, 82 and the internal braces 92 container therein, thereby enhancing the buoyancy effect of the empty chamber. Each shell 14, 16 is lined with structural foam or other buoyant material to neutralize the buoyancy of the chassis, strengthen the material forming the shells 14, 16, and insulate the components contained therein.

The coils are further configured to be isolated from the circuit sot that the load on the buoy may be adjusted, resulting in near fully submerged buoy that more precisely follows complex waves while also providing maximal buoyancy force for power take-off. The result at most times enables near fully submerged, wave-following buoys (most buoyancy force and driveshaft travel length responding to subject wave). At such instant buoys 24 and module 10 lower portions become more dependent systems than in normal operating conditions.

Sauro Rossi in-line swivel joint 1/2 inch BSP (M to F.. In operation, the assembly 10 floats in a body of water with the buoys 24 partially submerged at the surface, and the remaining part of the assembly 10 submerged in the water. The main body member 12 of the assembly 10 includes a top shell 14 and a bottom shell 16. The top shell 14 and bottom shell 16 are secured together around a chassis to form a water-tight inner cavity to contain the generator 18 and ballast control components. Referring to FIGS. 1, 2 and 5, each buoy 24 includes an upper shell 80 and a lower shell 82. The upper shell 80 and the lower shell 82 are secured together with rivets 84, or other suitable fasteners, around a superstructure 86 to form a water-tight chamber, thereby making the buoy 24 highly buoyant.

The drive rods 22 also may be partially or wholly filled with foam, or other buoyant material, to neutralize the buoyancy of the drive rod 22, thereby enhancing the buoyancy of the buoy 24. A secondary shock absorber 40 is attached to the lower end of the drive rod 22. The secondary shock absorber 40 of the drive rod 22 works in conjunction with the upper shock absorber 34 in the respective tubular framing member 20 to limit the upward travel of the drive rod 22 and reduce the stress thereon. In a typical deployment the module 10 are sized for deployment in an environment with wave size complimentary to the size of the module 10. The shock absorbers 32, 34 provide a mechanism to reduce stress and wear on the module during heavy seas.
