  • Patent number: 11592004
    Abstract: Provided is a vertical axis wind power generation device including a wind turbine of a vertical axis type including a support column, a main shaft disposed on an upper portion of the support column so as to be rotatable, a plurality of blades coupled to the main shaft through arms; a power generator; and a container having a standard dimension for freight transport. The wind turbine is accommodatable in a folded or disassembled state in the container together with the power generator. The container is provided with a support-column fixing part configured to fix the support column of the wind turbine to the container. The container may include an inclining mount inside the container, the inclining mount being configured to accommodate a folded body of the wind turbine.
