[0034] A third column 7 is connected to the bottom of the vertical wave energy generator set, and a plurality of auxiliary support columns 8 are welded to the third column 7 .

[0035] A horizontal wind turbine 2 is installed on the top of the first column 1 , and blades 3 are installed on the horizontal wind turbine 2 .

[0042] The blade fan 11 rotates under the push of waves, thereby driving the sleeve 6 to rotate.
