The foundation utilizes a steel-concrete structure and comprises a plurality of tanks which are respectively provided with an opening; a lower end of the tower column is installed on the foundation; and the wind turbine set is installed on an upper end of the tower column. When the offshore wind turbine complete set floats on water, the openings of the plurality of tanks are under the water, and the tank is injected with air or water, and the buoyancy and uprighting force are provided by the plurality of tanks, so as to keep the entire structure in a vertical floating state consistent with the state of installation on the offshore site, but without external force on the water. The use of the offshore wind turbine complete set of the present invention eliminates the need for large hoisting machinery and transportation vessels in the offshore operation, the operation can be easily performed with high ratio of success, and greatly reduces the cost. Moreover, the technical solutions of the present invention have advantages such as low construction noise, small area of sea bed disturbance, and no pollutant leakage during the offshore operation and are environment-friendly. ## Claims ### Claim 1 An offshore wind turbine complete set, characterized in comprising: a foundation utilizing a steel-concrete structure and including a plurality of tanks which are respectively provided with an opening, wherein the plurality of tanks include a middle tank surrounded by a plurality of side tanks that are symmetrically distributed around the middle tank, wherein the plurality of side tanks are further away from a center of gravity of the offshore wind turbine complete set than the middle tank so as to provide uprighting force, and wherein a volume of the middle tank is larger than the volume of each of the plurality of side tanks; a tower column, a lower end of which is installed on a pile cap of the foundation, a ballast tank being provided inside the pile cap of the foundation; and a wind turbine set, which is installed on an upper end of the tower column; wherein the openings of the plurality of tanks are under water when the offshore wind turbine complete set floats on the water, and the tanks are injected with air or the water, and the buoyancy and uprighting force are provided by the plurality of tanks, so as to keep the entire structure in a vertical floating state on the water consistent with the state of installation on the offshore site, but without external force. ### Claim 2 (depends on 1) The offshore wind turbine complete set according to claim 1, wherein each of the plurality of tanks is provided with a switchable through hole through or from which the air may be injected or released, so as to control negative pressure of each tank. ### Claim 3 (depends on 1) The offshore wind turbine complete set according to claim 1, wherein the center of gravity of the offshore wind turbine complete set lies in a center of the middle tank. ### Claim 4 (depends on 1) The offshore wind turbine complete set according to claim 1, wherein a cross section of the middle tank being square and wherein the side tanks include four side tanks symmetrically distributed around the middle tank. ### Claim 5 (depends on 2) The offshore wind turbine complete set according to claim 2, wherein the foundation is columnar in its entirety, with a ratio of its diameter to a height of the offshore wind turbine complete set not less than 0.2. ### Claim 6 (depends on 2) The offshore wind turbine complete set according to claim 2, wherein the foundation is columnar in its entirety, with a cross section being polygonal and a ratio of the polygonal span to a height of the offshore wind turbine complete set not less than 0.2. ### Claim 7 (depends on 2) The offshore wind turbine complete set according to claim 2, wherein the foundation is cylindrical, and a center upside of a cover of the foundation is fixed with the pile cap, an upper end of which is provided with an adapter ring by which the lower end of the tower column is installed on the pile cap. ### Claim 8 (depends on 7) The offshore wind turbine complete set according to claim 7, wherein the foundation is provided with wave-resistant and ice-breaking structures in a position of the pile cap, so as to weaken an influence of wave run-up and ice on the foundation. ### Claim 9 (depends on 2) The offshore wind turbine complete set according to claim 2, wherein the tower column employs a hollow steel-concrete structure. ### Claim 10 (depends on 2) The offshore wind turbine complete set according to claim 2, wherein internal and external surfaces of the foundation are further provided with a plurality of kinds of pressure sensors.
