6, another embodiment of the present invention may include the base member 100, the connecting member 200, the buoy member 300 and the power generation unit 400. Unlike the foresaid embodiment, only a single number of the base member 100, the connecting member 200 and power generation unit 400, respectively, may be provided, not the plural number.
The worn and damaged buoy member 300 would need to be replaced with new one. To prepare for the case in which the buoy member 300 needs to be replaced with new one, the buoy member 300 may be coupled detachably to the connecting member 200 using a coupling means 310 so that the buoy member 300 can be disassembled from the connecting member 200 when needed. Although the present embodiment refers to a power system using a combination of the wave force and the current force, depending on the location where the system is installed, the buoy member 300 to be installed in a location where the current force is relatively larger may have a circular cross-sectional shape, and the buoy member 300 to be installed in a location where the wave force is relatively larger may have an oval or airfoil cross-sectional shape.
Typically, the directions of wave force and current force will be the same at flood tide, and the magnitudes of wave force and current force may vary depending on the location within the ocean. The wave force and the current force may be different in magnitudes depending on marine environments or places where the buoy member 300 is installed. 8, since the buoy member 300 is less affected by the current force compared to the case of FIG. Since such a power generation principle is generally accepted as a well-known technology, a detailed description thereof is omitted in the specification.

The buoy member 300 may move together with the connecting members 200 due to the coupling of the buoy 300 to the connecting members 200. Since the buoy member 300 directly receives an external force such as the wave force and the current force, in a long term, the buoy member 300 may be worn and damaged.
