Described first cone gear 5 and second largest cone gear 7 are steel component.
In the present invention, elliposoidal pendulum mass is swung the working procedure converting unidirectional rotary motion to:
When electricity generating device is started working by state of rest, elliposoidal pendulum mass 1 swings from the top down, rotating shaft 3 turns clockwise in X direction, first overrunning clutch 4 is in jointing state, first cone gear 5 is driven to turn clockwise along X-axis direction, drive small conical gear axle to be rotated counterclockwise along Y direction, second largest cone gear 7 is rotated counterclockwise along X-axis direction under the drive of small conical gear 9.Because of the second overrunning clutch 6 and the first overrunning clutch 4 mirror antisymmetry, the second overrunning clutch 6 is in separated state, and second largest cone gear 7 dallies, and only plays the effect of flywheel, reduces the wave properties of running for stored energy.When elliposoidal pendulum mass 1 moves from lower to upper, rotating shaft 3 is rotated counterclockwise along X-axis direction, first overrunning clutch 4 is in separated state, first cone gear 5 dallies, in the short period of time, the speed of rotating shaft 3 is also less than the speed of second largest cone gear, second overrunning clutch 6 does not engage, the rotation function now stored primarily of two large conical gears drives small conical gear 9 to rotate, because the load effect of generator, two large conical gear speed reduce slightly, elliposoidal pendulum mass 1 moves to a certain moment from bottom to top, the speed of rotating shaft 3 starts the rotating speed being greater than the second cone gear 7, second overrunning clutch 6 engages, second largest cone gear 7 is driven to continue to rotate counterclockwise along X-axis direction, drive small conical gear axle 9 to continue to be rotated counterclockwise along Y direction simultaneously.Elliposoidal pendulum mass 1 replaces reciprocally swinging, the first overrunning clutch 4 and the second overrunning clutch 6 driven, drive electrical generators 14 continuous and stable electric generation, and two bevel gear wheels of alternately idle running serve the effect of flywheel, significantly fall slow-revving wave properties.
When wave is larger, elliposoidal pendulum mass 13 has and larger rotates freely angle around the shaft, can not be impacted, improve the ability of anti-wave because corner restriction.After elliposoidal pendulum mass 1 overturns 180 °, turning to of small conical gear 9 is constant, and electricity generating device is consistent with not overturning front performance characteristic.When after upset, elliposoidal pendulum mass 1 moves from the top down, the second overrunning clutch 6 engages, and when moving from bottom to top, the first overrunning clutch 4 combines.Elliposoidal pendulum mass 1 has rotational symmetry, and the upper and lower wave energy of dominant absorption wave, when propagation of ocean waves direction changes, the S. E. A. of elliposoidal pendulum mass 1 is constant.
