The legs 1 can be fixed on the deck of an offshore wind power installation vessel. For example, the height of the outrigger 1 may be about 10 m in general, but the height of the outrigger 1 is not particularly limited and may be determined according to the height of the tower, for example, the height of the outrigger 1 may be set to a predetermined proportion of the height of the tower, such as the height of the outrigger 1 may be set to about 1/10 or higher of the height of the tower. The legs 1 may be provided with lifting points to facilitate assembly of the support frame 21.

By symmetrically arranging the first telescopic parts 10, the tower is uniformly stressed, and the alignment and fine adjustment effects between the flanges can be conveniently ensured. In order to accurately monitor the alignment condition of the bottom flange of the tower and the fixing flange, the tower fixing device for the offshore wind power installation vessel can be further provided with a detector and a controller. For example, a sensor may be disposed on at least one of the bottom flange and the fixed flange to accurately determine the alignment condition of the bottom flange and the fixed flange, so as to achieve real-time monitoring, control and precise adjustment of the relative positions of the bottom flange and the fixed flange. In addition, under offshore tower section of thick bamboo vertical type transportation operating mode, can also keep certain transverse force to a tower section of thick bamboo above through first pars contractilis 10, increase the stability of tower section of thick bamboo vertical type transportation.

For example, the second stretchable and contractible portions 17 are arranged at equal angular intervals radially in the circumferential direction around the fixing flange 19. To facilitate adjusting the position of the bottom flange of the tower in all directions into alignment with the fixing flanges 19, three or more second telescopic parts 17 may be arranged in the circumferential direction of one fixing flange 19. For example, four second stretchable and contractible portions 17 may be arranged at 90-degree angular intervals in the circumferential direction. However, the embodiment of the present invention is not limited thereto, and the number of the second telescopic parts 17 may also be less than four, for example, three or two, and as the number of the second telescopic parts 17 decreases, for example, the structure thereof becomes simpler, but the alignment and fine adjustment effect of the bottom flange and the fixing flange of the tower may become worse; or the number of the second telescopic parts 17 may be more than four, for example, five, six, seven, eight, etc., and as the number of the second telescopic parts 17 increases, the structure thereof becomes complicated, and the aligning and fine-tuning effects of the bottom flange of the tower and the fixing flange thereof are better.
