Wave power plant and transmission
InactiveCN102016294AReduce complexityHigh capacity factorWorking fluid for enginesMachines/enginesCouplingBuoy
A wave power generating equipment (1) includes a buoy (3) and a power train (2). In the transmission unit there is a driveshaft (11), which is driven to rotate either when the buoy rises or sinks, yet always in the same direction. The driveshaft is mechanically coupled to one of the rotating parts (21') of an electric generator (21) and drives this to generate electric current. Further on there is provided an energy accumulation device (105), which is also coupled to the driveshaft to accumulate energy when the buoy rises or sinks and the driveshaft rotates and which is then used to drive the generator at the other of the rising- and sinking motions. The coupling between the energy accumulation device and the driveshaft can go by the generator's second rotatable part (21'), the air gap between the generator's parts and the generator's first part. The coupling over the air gap gives a torque, which drives the second part to rotate along and which also counteracts the rotation of the driveshaft. The generator's second part is driven by the energy accumulation device to rotate in the other direction, when the torque from the driveshaft does not exceed the counteracting torque.
