Referring to the ninth and tenth diagrams, when the hull 200 arrives at the second location, the user only needs to increase the ballast of the hull 200 to land the hull 200 on the seabed 300. The hull 200 can be stably positioned at the second location to avoid the influence of the sea waves and further improve the safety of the operation. After that, the user simply removes the platform 400 and lowers the base 10 to the second position. At the two locations, the column 40 is pulled out of the through hole 11 of the base 10 to form a space between the base 10 and the column 40, so that the user can further deposit the connector previously stored on the hull 200. 20 sets are arranged on the base 10, and finally the user can complete the assembly of the wind power generator 100 by simply assembling the tower 40 to the connecting member 20.

Referring to FIG. 11 and FIG. 12 again, after the user completes the assembly of the wind power generator 100, the user only needs to release the ballast of the hull 200 as shown in FIG. Passing the hull 200 away from the seabed 300 and driving away from the ship as shown in Fig. The body 200 can complete the installation of the wind turbine 100.

Thereby, the present invention can complete the pre-set wind turbine 100' prior to the first location, and then directly transport the pre-grouped wind turbine 100' to the second location through the hull 200 for assembly. Installation, in order to greatly shorten the installation time of the wind power generator 100, and during the transportation, since the tower 40 is threaded through the through hole 11 of the base 10, the height of the wind power generator 100 can be greatly reduced to shorten The length of the arm reduces the sloshing caused by wind and waves, which not only improves the stability of the transportation, but also enables the invention to be transported using a hull with a smaller tonnage to achieve a cost saving effect.

Referring to the thirteenth, fourteenth and fifteenth drawings, a partial exploded view, a partially enlarged cross-sectional view and a sectional view of the cushioning member of the second preferred embodiment of the present invention, the wind power generator The assembly structure of the 100 is different from the foregoing first preferred embodiment in that the connecting member 20 is further provided with at least one positioning post 23, and the column 40 is provided with a positioning corresponding to the positioning post 23.
