A stable power-output device with a linear long-shaft driven by wave

This invention relates to a stable power-output device driven by waves, the power-output device consists of buoys (1), and a scaffold with buoys (1), guiding tracks (2) and rotating shafts (3) installed. The scaffold floats on the wave, roller wheels (4) are installed at two sides of the buoys (1), with each two of the roller wheels (4) are sandwiched between the related guiding track (2) and the related side of each buoy (1) so that the roller wheels (4) and the guiding tracks (2) can work together. Guiding devices (5) are installed on top of the buoys (1); rotating shafts (3) are connected to the guiding devices (5) and float horizontally on the waves. Ratchets are installed on the short shafts (3); they are in contact with the guiding devices (5). A shaft connector (6) is adapted to connect each two of the rotating shafts (3) together and form a long shaft (7).
