When the power generating device (1) provided by the present invention is in use, the power generating device (1) can be installed at a seashore (3). When the seawater flows toward the seashore (3), a part of the wave (2) is allowed to flow into the resonating case (31) of the resonating member (30). At this moment, the wave (2) is moved towards the inward direction of the first chamber (11), the gas pressure inside the first chamber (11) is higher than the gas pressure inside the second chamber (12) thereby driving the quantitative liquid (20) to flow from the first chamber (11) to the second chamber (12), and the wave (2) flowing towards the second chamber (12) is enabled to pass the communicating hole (13) thereby driving the driving member (50) to rotate towards one direction (counterclockwise according to this embodiment).

Please refer to FIG. 6 and FIG. 7, wherein FIG. 6 is another schematic view illustrating the operation of the power generating device utilizing oscillating water for converting into wave power according to the first embodiment of the present invention; and FIG. 7 is another schematic view illustrating the water flowing status of the power generating device utilizing oscillating water for converting into wave power according to the first embodiment of the present invention. When the seawater flows away from the seashore (3), the wave inside the resonating case (31) flows towards the outward direction of the first chamber (11), at this moment the gas pressure inside the first chamber (11) is lower than the gas pressure inside the second chamber (12) thereby driving the quantitative liquid (20) to flow from the second chamber (12) to the first chamber (11), and the wave (2) flowing towards the first chamber (11) is enabled to pass the communicating hole (13) thereby driving the driving member (50) to continuously rotate towards the same direction (counterclockwise according to this embodiment).
Accordingly, during the reciprocal movement of the wave (2), the quantitative gas (40) inside the resonating case (31) is pushed and squeezed thereby enabling the quantitative liquid (20) to push the driving member (50), and the driving member (50) drives the power generating motor (60) to rotate so as to achieve the objective of generating electric power through the wave.
Please refer to FIG. 8, which is a schematic view illustrating the power generating device utilizing oscillating water for converting into wave power according to an alternative of the first embodiment of the present invention. As shown in FIG. 8, the driving member (50) is an axial turbine. The technical feature of the axial turbine is that the blades thereof are able to constantly rotate towards the same direction without being interfered by the water flowing direction.
Please refer to FIG. 9 and FIG. 10, wherein FIG. 9 is a schematic view illustrating the power generating device utilizing oscillating water for converting into wave power according a second embodiment of the present invention; and FIG. 10 is a schematic view illustrating the operation of the power generating device utilizing oscillating water for converting into wave power according the second embodiment of the present invention. The difference between this second embodiment and the first embodiment is that a driving member (50′) is disposed in the second chamber (12), and the driving member (50′) is a buoy (52) having a gear rack (51). Through a plurality of rollers (53), the gear rack (51) is able to guide the buoy (52) thereby enabling the buoy (52) to be upwardly/downwardly moved with the quantitative liquid (20) along the inner wall of the second chamber (12). In addition, the power generating motor (60) further includes a gear box (61) driven by the gear rack (51).
When the wave (2) flows towards the inward direction of the first chamber (11), the quantitative gas (40) drives the quantitative liquid (20) to be upwardly moved, and the buoy (52) is driven by the quantitative liquid (20) to be upwardly moved along the inner wall of the second chamber (12), at this moment the upward-moving gear rack (51) drives the gear box (61) to operate, then the gear box (61) further drives the power generating motor (60) to generate electric power so as to be outputted; on the other hand, when the wave (2) flows towards the outward direction of the first chamber (11), the quantitative liquid (20) is downwardly moved, at this moment the buoy (52) takes advantage of its self-weight for being downwardly moved along the inner wall of the second chamber (12); accordingly, the driving member (50′) is pushed by the quantitative liquid (20) for performing the reciprocal movement thereby driving the power generating motor (60) to generate electric power.
Please refer to FIG. 11, which is a schematic view illustrating the power generating device utilizing oscillating water for converting into wave power according a third embodiment of the present invention. This embodiment is substantially the same as the previous embodiment, but the difference is the driving member. According to the third embodiment, a driving member (50′′) is a buoy (52′′) having a mobile coil (51′′). The buoy (52′′) is upwardly/downwardly moved with the quantitative liquid (20) along the inner wall of the second chamber (12). In addition, the driving member (50′′) further includes a fixed coil (53′′) disposed in the second chamber (12) and fastened by a supporter (54′′). In actual practice, the mobile coil (51′′) forms a relative movement with the fixed coil (53′′) through the upward/downward movement of the buoy (52′′), the above-mentioned relative movement is able to cut magnetic fields thereby generating electric power.
Although the present invention has been described with reference to the foregoing preferred embodiment, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
