Overwater inflatable platform spiral wind power generation device

The utility model belongs to the technical field of overwater wind power generation, and particularly relates to an overwater inflatable platform spiral wind power generation device which comprises an overwater inflatable platform, a rotary base, a stand column, a generator, an outer rotating ring, an inner rotating ring and a spiral wind power rod. The rotary base is rotatably arranged at the top of the overwater inflation platform; the outer rotating ring is connected to the rotary base through a stand column and can vertically turn over. The inner rotating ring is rotationally connected into the outer rotating ring and can turn over in the horizontal direction and the vertical direction in an inclined mode; the generator is fixed in the center of the inner rotating ring; and the spiral wind power rod is provided with a spiral blade and is coaxially connected with a rotating shaft of the generator. Wind power transmission is carried out through the spiral wind power rod which is obliquely arranged, so that
