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.

First claim

What is claimed is:

1. A vertical axis wind power generation device comprising:
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 about a vertical axis, a plurality of blades extending in a vertical direction around the main shaft and coupled to the main shaft through arms;
a power generator configured to generate electric power by rotation of the main shaft; and
a container having a standard dimension for freight transport,
wherein
the wind turbine is accommodatable 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, and
the support-column fixing part includes a two-pronged metal fitting having a semicircular receiving part matching a part of an outer periphery of the support column and a base end fixed to a lower surface of a ceiling of the container.

2. The vertical axis wind power generation device as claimed in claim 1 , wherein the wind turbine of the vertical axis type is foldable or able to be disassembled.

3. The vertical axis wind power generation device as claimed in claim 1 , wherein the container includes a double door configured to open and close the opening at the longitudinal end of the container, and the door in an opened state serves as outriggers.

4. The vertical axis wind power generation device as claimed in claim 3 , wherein the container includes an inner door disposed an inner side of the double door and configured to prevent entry from an outside.

5. The vertical axis wind power generation device as claimed in claim 1 , comprising: a solar panel assembled with a stand so as to be installable outside or on the container and configured to photovoltaically generate electric power; and a secondary battery configured to store the generated electric power, the solar panel and the secondary battery being accommodatable in the container together with the wind turbine in the folded or disassembled state.

6. The vertical axis wind power generation device as claimed in claim 1 , comprising: a main-shaft-unit folding mechanism configured to allow a main shaft unit including the support column and the main shaft to be folded; and a blade-unit folding mechanism configured to allow blade units, which are constituted by the blades and the arms, to be folded along the main shaft unit in a folded state.

7. The vertical axis wind power generation device as claimed in claim 6 , wherein the main-shaft-unit folding mechanism includes a support-column tilting mechanism coupling the support column to a wind turbine mount in a tiltable manner.

8. The vertical axis wind power generation device as claimed in claim 6 , wherein the main-shaft-unit folding mechanism includes a main-shaft tilting coupling mechanism coupling a main-shaft lower-end supporting member located at an upper end of the support column and rotatably supporting the main shaft at a lower end of the main shaft to the upper end of the support column such that the main shaft is tiltable, the main-shaft tilting coupling mechanism being configured to cause the main shaft in a laid state to assume a posture along the support column.

9. The vertical axis wind power generation device as claimed in claim 6 , wherein the blade-unit folding mechanism includes rotary coupling members provided to the respective blades and disposed around the main shaft so as to be rotatable, the rotary coupling members being coupled to base ends of the respective arms.

10. The vertical axis wind power generation device as claimed in claim 6 , wherein the blade-unit folding mechanism includes arm-base-end bending coupling parts coupling base ends of the arms to the main shaft in a bendable manner and arm-tip-end bending coupling parts coupling tip ends of the arms to the blades in a bendable manner.

11. The vertical axis wind power generation device as claimed in claim 1 , wherein the container is provided with a linear guiding device configured to guide the wind turbine so as to allow the wind turbine to be lifted and lowered between a use position at which the blades project upward from a height range of the container and an accommodation position at which the blades are accommodated within the height range of the container.

12. The vertical axis wind power generation device as claimed in claim 11 , comprising a lifting device of a winding type configured to wind a winding member connected to an upper portion of the container and a lower portion of the support column such that the wind turbine can be lifted and lowered.

13. The vertical axis wind power generation device as claimed in claim 12 , wherein the lifting device is of an electrically-powered type which is configured to be driven by an electric motor to perform winding operation.

14. The vertical axis wind power generation device as claimed in claim 11 , wherein the container has a ceiling surface having an upper opening configured to allow the wind turbine to move in and out therethrough, and the support column is provided with an inner lid configured to tightly close the upper opening when the wind turbine is raised.

15. A vertical axis wind power generation device comprising:
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 about a vertical axis, a plurality of blades extending in a vertical direction around the main shaft and coupled to the main shaft through arms;
a power generator configured to generate electric power by rotation of the main shaft; and
a container having a standard dimension for freight transport,
wherein
the wind turbine is accommodatable 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,
