Floating oscillating water column-type wave energy power generation

A floating oscillating water column-type wave energy power generation apparatus, comprising a first chamber and a protective cap,

• wherein a nozzle is mounted inside the first chamber;
• a flow-guiding cone is coaxially mounted below the nozzle with respect to a direction of gravity, and the flow-guiding cone is conical and arranged with a tip facing down with respect to said direction of gravity;
• an impeller is coaxially mounted above the nozzle with respect to said direction of gravity;
• a power generator is coaxially mounted above the impeller with respect to said direction of gravity;
• wherein the protective cap is mounted at a top of the first chamber;
• wherein a gap is provided between an edge of the protective cap and an outer circumferential edge of the first chamber for air circulation,
• wherein the protective cap is a semi-spherical shell structure and is disposed on the outer circumferential edge of the first chamber with a spherical surface of the semi-spherical shell structure of the protective cap facing upwards with respect to said direction of gravity;
• wherein the protective cap is uniformly provided with a plurality of air-permeable holes on the spherical surface;
• wherein the nozzle includes a disc structure in a middle of the nozzle and a ring structure at a periphery of the nozzle, and the nozzle includes flowing-guide vanes arranged such that the flowing-guide vanes are distributed radially and equidistantly between the disc structure and the ring structure, wherein the flowing-guide vanes are arranged such that an axis of the flowing-guide vanes is disposed at a center of the flowing-guide vanes;
• and
• wherein a second chamber is mounted under the first chamber and communicate s with the first chamber in the direction of gravity,
• wherein the first chamber is a cylindrical structure, is hollow and is provided with a plurality of circular air valves, wherein the tip of the flow-guiding cone is disposed at a same height as at least a portion of the plurality of circular air valves with respect to said direction of gravity such that the tip of the flow-guiding cone is enclosed between the plurality of circular air valves.
