AN OFFSHORE FLOATING WIND TURBINE FOR ELECTRIC POWER GENERATION

摘要

An offshore floating wind turbine for electric power generation comprising a tower (1) with a bottom portion (1 b) water-tightly connected to an upper portion of a water-tight container body (1d) which comprises an inner machine room (12) housing an electric power generator (22); an inner hollow (1c) of the tower (1) extending into the machine room (12); transmission means (4) extending through the inner hollow (1c) of the tower (1), for transmitting rotational movement of the rotor (25) to the electric power generator (22); receiving portion (2a) of the floating base (2) into which at least a lower portion of the container body (1d) is rotatably inserted; driving means (11) driven by at least one electric motor (3) and arranged around an outer peripheral portion (1 e) of the container body (1d) to engage the peripheral portion (1e) to rotate the container body (1d) within the receiving portion (2a).
