Patent ID: 7679204

Claim:
A power device for generating power, comprises: a turntable, provided pivotally at equal interval along its peripheral direction with a plurality of rod bodies, wherein said rod bodies are provided at their ends near the periphery of the turntable with heavy blocks, while said rod bodies are engaged at their front ends near the center of the turntable with a spring that has its other end engaged on the turntable, thereby the swinging of said rod bodies would drive the spring to stretch or contract; and a top-pushing rod, driven by a motor such that said top-pushing rod can move reciprocally along a linear direction in which it can push the heavy block on a rod body above said turntable so as to bring said heavy block returning to the highest position of the turntable, wherein said turntable is provided with four said rod bodies at the upper, lower, left and right sides of said turntable, respectively, wherein said rod bodies above and below said turntable is in vertical position, and springs above them is in a state of contraction; said rod body at the left side of said turntable is in horizontal position, and the spring on it is in a state of contraction; while the rod body at the right side of said turntable is in vertical position, and the spring on it is in a state of stretching, whereby, when said turntable rotates counterclockwise, the rod body above the turntable is driven to rotate to the left side of the turntable, and is in a horizontal position, and the spring on it is in a state of contraction, the rod body at the left side of the turntable is driven to rotate to the lower side of the turntable, and is in a vertical position, and the spring on it is in a state of contraction, the rod body originally in vertical position below the turntable is driven to the right side of the turntable and becomes in vertical position, and the spring on it becomes in a state of stretching due to the vertical position of said rod body, while the rod body originally in vertical position at the right side of the turntable is driven to rotate to the upper side of the turntable and is in a horizontal position, which becomes in a vertical position due to the top pushing of the heavy block by the top-pushing rod, thereby the originally stretched spring will become contracted, the power device further comprises a stopping block provided on said turntable to prevent said rod body from shaking.
