Fit tightly therewith after ogee changeover portion.
Wind energy the most according to claim 8-wave energy-tide energy combination electrification structure, it is characterised in that: described electromotor
Quantity be 2, be symmetrically distributed in the both sides of tube-in-tube structure.
10. the construction method of wind energy-wave energy-tide energy combination electrification structure, it is characterised in that comprise the steps:
(1) type oscillating floater wave energy generating set and the manufacturing of tidal current energy generating equipment it are combined, simultaneously at dock
In prefabricated compound bucket foundation；
(2) compound bucket foundation towage to offshore is assembled place, carry out the assembling of wind-driven generator and tidal current energy generating equipment；
(3) utilize the buoyancy of compound bucket foundation by wind-driven generator and tidal current energy generating equipment towage to designated mounting marine site,
And carry out the negative pressure sinking installation on basis；
(4) on the basis of combined oscillating floater wave energy generating set being installed to compound cartridge type, thus electrification structure is completed
Construction.
