Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, each [a] is a plan view, each [b] is a side view, each [c] is a three-dimensional view,

"A" of FIG. 3 is a view showing another example of the corresponding site.

As shown in Figures 1 to 3, the system block for offshore wind power support structure according to the present invention,

And comprises a bottom block 10, a middle block 20 and a top block 30.

Looking at each configuration,

Bottom block 10 is

As shown in FIG. 1,

It is put in a spoon,

Female or male fitting portion 11 formed on the upper portion, and

Final insert 12 formed through the top and bottom

It is made, including.

The bottom block 10 serves as a base (foundation frame) to be initially placed on the seabed,

By forming the seawater flow passage 13 in the form of open to the lower side on each side slope (four sides), the seawater has a flow structure that can naturally flow in and out.

In addition, the upper opening 14 penetrating downward from the upper central region to be connected to the seawater flow passage 13 is formed, so that the unit area through which the hydraulic pressure acts as compared with the non-formed upper opening 14 is formed. Can be reduced.

In the present invention, the fitting portion 11 has a protruding male configuration,

In addition, the fitting portion 11 is arranged in four places radially from the upper center.

The final insertion portion 12 is arranged radially at four locations from the upper center, and is arranged between the fitting portions 11 arranged at the four locations.
