  • FLOATING OSCILLATING WATER COLUMN-TYPE WAVE ENERGY POWER GENERATION APPARATUS
    Publication number: 20230366369
    Abstract: A floating oscillating water column-type wave energy power generation apparatus includes a first runner chamber and a protective cap, wherein a nozzle is mounted inside the first runner chamber, a flow-guiding cone is coaxially mounted below the nozzle, the flow-guiding cone is conical and arranged with a tip facing down; an impeller is coaxially mounted above the nozzle; a power generator is coaxially mounted above the impeller; the protective cap is mounted at the top of the first runner chamber; and a gap is provided between an edge of the protective cap and an edge of the first runner chamber for air circulation. According to the floating oscillating water column-type wave energy power generation apparatus, as the nozzle with the flow-guiding cone structure is used, the flow-guiding cone can guide air flowing, and increase the air flowing speed in the apparatus.

  • Constant tension anchoring system
    Patent number: 10486774
    Abstract: A constant tension anchoring system mounted on a floating body in the ocean includes an anchor, an anchor chain, an anchor windlass, a towing cable, a load and a chain stopper. During the oscillatory motion of the waves, the constant tension anchoring system repeats the release and retraction so as to maintain a generally constant tension force and thereby ensure the safety of the anchoring system and the floating body.
