Abstract

The invention provides an offshore floating type wind turbine foundation, an offshore wind turbine and a mounting method of the offshore wind turbine. The wind turbine foundation comprises a supporting platform, a plurality of floating cylinders and a plurality of movable arms. The plurality of movable arms are distributed in the circumferential direction of the supporting platform, one end of each movable arm is movably connected with the supporting platform, the other end of each movable arm is provided with one floating cylinder, and the plurality of movable arms have first positions and second positions; and the height of the end, provided with the floating cylinder, of each movable arm at the first position is larger than that of the end at the second position, and the supporting platform is in the same posture when the offshore wind turbine is transported and the offshore wind turbine works. The offshore wind turbine comprises the wind turbine foundation. The mounting method of the offshore wind turbine is used for mounting the offshore wind turbine. According to the scheme, in the transportation process of the offshore wind turbine, the plurality of movable arms are locatedat the first positions, and after the offshore wind turbine is transported in place, the plurality of movable arms are switched to the second positions from the first positions so that mounting of theoffshore wind turbine can be achieved, and the transportation and installation processes of the offshore wind turbine are simplified.

Description

technical field [0001] The present application relates to the technical field of wind power, in particular, to an offshore floating wind turbine foundation, an offshore wind turbine and an installation method for the offshore wind turbine. Background technique [0002] Offshore wind resource reserves are abundant, mainly distributed in deep and open sea areas. For example, more than 80% and 58% of the offshore wind energy in Europe and the United States are located in areas with a water depth of more than 60 meters, and more than 85% of the offshore wind energy in Japan is located in sea areas with a water depth greater than 100m. In the face of harsh environmental conditions in the deep sea, the technical and economic challenges of traditional offshore fixed wind power have increased sharply, and wind power giants are gradually focusing on the research and development of floating wind power technology. [0003] Many new floating wind turbine foundations have emerged, such ...
