## Background
CROSS-REFERENCE TO RELATED ART
This Invention is a continuation-in-part of U.S. Ser. No. 13/760,162, entitled “Wave-Making and Power Generating System” filed on Feb. 6, 2013 and currently pending.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to power generation technology, and more particularly to a wave-driven power generation system, which moves wave-making barrels in water reservoirs alternatively up and down to create water waves, forcing float boards to move a transmission gearbox in transferring rotary driving force through an inertial wheel set to a power generating unit for generating electricity.
2. Description of the Related Art
Although nuclear power is an effective source of power, the problems of nuclear waste disposal and nuclear power safety have always been controversial. At present, thermal power can provide livelihood electricity, however it is not in line with the principles of environmental protection and its cost is also high. Further, wind-driven and solar power generators are environmentally friendly; however, their cost is high. Further, wind-driven and solar power generators are subject to weather restrictions. Further, hydroelectricity is the production of electrical power through the use of the gravitational force of falling or flowing water, however, the level of gravitational force of falling or flowing water affects the performance of hydroelectric power generation. Further, hydroelectric power plants must be built near dams and water sources, so they are likely to be small and geographically limited.
Therefore, it is desirable to provide a power generation system that is free from geographical limitations, cost-effective and environmentally friendly, and that does not cause pollutions or produce waste materials.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a wave-driven power generation system consisting of a rocker bar, two wave-making barrels, a motor reducer, a water reservoir, a float board, second and third links, first and second rocker arms, and two transmission mechanisms, wherein the wave-making barrels that are respectively pivotally connected to the two opposite ends of the rocker bar have a respective beveled bottom face; the double beveled protruding block of the water reservoir defines two reversed bevel surfaces that respectively face toward the beveled bottom faces of the wave-making barrels in a parallel relationship; the float board is pivotally supported on the rod member in the water reservoir and has two beveled lateral faces respectively located at two opposite lateral sides thereof and respectively sloping in direction reversed to the sloping directions of the beveled bottom faces of the wave-making barrels; thus, the wave-making barrels can effectively create water waves in the water reservoir to move the float board and the transmission mechanisms and to further drive the power generators to generate electrical power supply efficiently.
It is another object of the present invention to provide a wave-driven power generation system, which consumes simply a small amount of electricity to drive wave-making barrels in creating water waves for moving power generators to generate electrical power supply efficiently.
It is still another object of the present invention to provide a wave-driven power generation system, which is free from geometrical limitations, less expensive for a wide range of applications and in line with the principles of environmental protection, and, which does not cause pollution or produce waste materials and allows repeated use of the supplied water.

a float board 6 that is supported on and movable up and down with the water level in the water reservoir 5 and that comprises a bottom recess 61 located at a bottom side thereof and adapted for receiving an upper part of the double beveled protruding block 53 of the water reservoir 5 when the float board 6 is lowered in the water reservoir 5, two bottom guide surfaces 611 and 612 that are defined in the bottom recess 61 at two opposite lateral sides and respectively kept away from the double beveled protruding block 53 when its upper part is received in the bottom recess 61, and two beveled lateral faces 62 and 63 respectively located at two opposite lateral sides thereof and respectively sloping in direction reversed to the sloping directions of the beveled bottom faces 31 and 32 of the wave-making barrels 3;
a second link 64 and a third link 65 respectively pivotally connected with respective bottom ends thereof to opposing left and right sides of the float board 6;
a first rocker arm 66 and a second rocker arm 67 respectively pivotally connected with respective one ends thereof to respective opposite top ends of the second and third links 64 and 65;

Further, the transmission mechanisms 7 and 7′ each comprise a first transmission gearwheel 71 or 71′ respectively pivotally connected with the respective opposite ends of the first and second rocker arms 66 and 67 (see FIG. 1, FIG. 4 and FIG. 5), a second transmission gearwheel 73 or 73′, a first transmission shaft 72 connected between the first transmission gearwheel 71 or 71′ and the second transmission gearwheel 73 or 73′, a small idle gear 741 or 741′ meshed with the second transmission gearwheel 73 or 73′, a second small gear 75 or 75′ meshed with the small idle gear 741 or 741′, a second transmission shaft 76 or 76′ rotatable with the second small gear 75 or 75′, a plurality of sprocket wheels or belt pulleys 77 or 77′ mounted on and rotatable with the second transmission shaft 76 or 76′, a third transmission shaft 79 or 79′ disposed in parallel to the second transmission shaft 76 or 76′, a plurality of chains or belts 78 or 78′ respectively coupled between the sprocket wheels or belt pulleys 77 or 77′ and the third transmission shaft 79 or 79′, a fourth transmission shaft 701 or 701′ coupled with the respectively power generators 8 or 8′, and a plurality of inertia wheel sets 70 and 70′ respectively coupled between the third transmission shaft 79 or 79′ and the fourth transmission shaft 701 or 701′.
Thus, when the motor reducer 4 is started to rotate the output shaft 41, the eccentric wheel 42 is rotated to bias the rocker bar 2 on the pivot member 1, moving the first links 33 and 34 and the wave-making barrels 3 alternatively up and down to create water waves in the water reservoirs 5. At this time, the float board 6 is turned about the rod member 10 alternatively up and down to move the transmission mechanisms 7 and 7′ via the second and third links 64 and 65 and the first and second rocker arm 66 and 67, and thus the inertia wheel sets 70 and 70′ of the transmission mechanisms 7 and 7′ are rotated to move the power generators 8 and 8′, driving them to generate electrical power supply.
Further, the float board 6 is selected from the material group of metal, cement, metal reinforced cement and cement mixture.
Further, the water reservoir 5 can be made of high-strength metal, high-strength plastics, cement, cement mixture, or any other high-strength material, in the form of a top-open water container.
In conclusion, the invention provides a wave-driven power generation system that has advantages and features as follows:
1.
