| 20110258998 | DEVICE FOR A WINCH-OPERATED WAVE-POWER PLANT - A device for a winch-operated wave-power plant with a self-tightening winch connecting a wave-energy-absorbing body via a winch wire to a reference point. A winch cable drum is connected via a mechanical energy absorption- and conversion system to a rotating outgoing axle. The mechanical energy absorption- and conversion system is connected to a slip clutch. The slip clutch is arranged between the winch axle and the outgoing axle. The slip clutch can be set to slip, thereby reducing the flow of mechanical rotational energy from the rotating winch through the mechanical energy absorption- and conversion system, so that the amount of energy per time unit absorbed by the mechanical energy absorption- and conversion system is limited by how much the slip clutch slips. The system further includes a governing system controlling the slip clutch by acting upon excessive speed and/or forces in the winch and the winch axle. | 10-27-2011 |
| 20100064679 | DEVICE FOR A WINCH-OPERATED WAVE-POWER PLANT - A device for a wave-power plant includes a self-tightening winch with a winch wire. The winch wire is connected to a wave-power-operated absorption element at one end and to a cable drum of the self-tightening winch at the other end. The cable drum is connected via a transmission system to an outgoing axle which is further connected to an energy-storing restructuring machinery. Movement of the absorption element results in rotation of the cable drum and transmission of mechanical energy from the cable drum to the rotating outgoing axle and to the restructuring machinery. The transmission system includes a slip clutch connected to the outgoing axle, which protects the components in the wave-power plant, particularly the components in the restructuring machinery, against overload in the event of large wave amplitude. The engagement of the slip clutch varies depending on the rotational speed or torque of the outgoing axel, thereby providing a maximum threshold for how great an amount of energy per time unit can be transmitted to the outgoing axle and to the energy-storing restructuring machinery. | 03-18-2010 |
