CROSS-REFERENCE TO RELATED ART 
       [0001]    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 
       [0002]    1. Field of the Invention 
         [0003]    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. 
         [0004]    2. Description of the Related Art 
         [0005]    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. 
         [0006]    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 
       [0007]    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. 
         [0008]    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. 
         [0009]    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.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0015]    Referring to  FIGS. 1-5 , a wave-driven power generation system in accordance with the present invention is shown. The wave-driven power generation system comprises: 
         [0016]    a rocker bar  2  having a pivot member  1  located on the middle thereof and pivotally connected to a water reservoir  5  in a balanced manner, two opposite ends thereof respectively pivotally coupled with a respective wave-making barrel  3  and coupling means, for example, a coupling groove  21  located at one side relative to the pivot member  1  and coupled to a motor reducer  4 ; 
         [0017]    two wave-making barrels  3  each having a respective first link  33  or  34  pivotally provided at a top side thereof and respectively pivotally connected to two opposite ends of the rocker bar  2  and alternatively movable up and down with the rocker bar  2  to oscillate water in the water reservoir  5 , and a respective beveled bottom face  31  or  32  sloping in a reversed direction relative to each other; 
         [0018]    a motor reducer  4  comprising an output shaft  41  for power output and an eccentric wheel  42  mounted at the distal end of the output shaft  41  and coupled to the coupling groove  21  of the rocker bar  2  and rotatable to move the rocker bar  2  alternatively up and down; 
         [0019]    a water reservoir  5  comprising a support frame  50  affixed to two opposite upright walls  51  thereof (see  FIG. 2 ), a pivot support  501  located at a middle part of a top side of the support frame  50  to pivotally support the pivot member  1  of the rocker bar  2  (see  FIG. 2 ), a rod member  10  transversely connected between the two opposite upright walls  51  at a suitable elevation (see  FIG. 2 ) for pivotally supporting a float board  6  (see  FIG. 1 ), and a double beveled protruding block  53  raised from a top surface of a bottom wall thereof (see  FIG. 1 ) and defining two reversed bevel surfaces  531  and  532  that respectively face toward the beveled bottom face  31  and  32  of the wave-making barrel  3  in a parallel relationship; 
         [0020]    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 ; 
         [0021]    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 ; 
         [0022]    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 ; 
         [0023]    two transmission mechanisms  7  and  7 ′ respectively pivotally connected with respective opposite ends of the first and second rocker arms  66  and  67  (see  FIG. 1 ,  FIG. 4  and  FIG. 5 ); and 
         [0024]    a plurality of power generators  8  and  8 ′ drivable by the transmission mechanisms  7  and  7 ′ to generate electrical power supply. 
         [0025]    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 ′. 
         [0026]    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. 
         [0027]    Further, the float board  6  is selected from the material group of metal, cement, metal reinforced cement and cement mixture. 
         [0028]    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. 
         [0029]    In conclusion, the invention provides a wave-driven power generation system that has advantages and features as follows: 
         [0030]    1. The wave-making barrels  3  that are respectively pivotally connected to the two opposite ends of the rocker bar  2  have a respective beveled bottom face  31  or  32 ; the double beveled protruding block  53  of the water reservoir  5  defines two reversed bevel surfaces  531  and  532  that respectively face toward the beveled bottom face  31  and  32  of the wave-making barrel  3  in a parallel relationship; the float board  6  is pivotally supported on the rod member  10  in the water reservoir  5  and has 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 ; thus, the wave-making barrels  3  can effectively create water waves in the water reservoir  5  to move the float board  6  and the transmission mechanisms  7  and  7 ′ and to further drive the power generators  8  and  8 ′ to generate electrical power supply efficiently. 
         [0031]    2. The wave-driven power generation system consumes simply a small amount of electricity to drive wave-making barrels in creating water waves for moving the power generators to generate electrical power supply efficiently. 
         [0032]    3. The wave-driven power generation system 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.
