Gravity assisted rotary mechanism and matched power generation device thereof

A gravity assisted rotary mechanism (1) and a matched power generation device (5) thereof are provided. The gravity assisted rotary mechanism (1) includes a plurality of rotating elements (10, 11, 12, 13) rotating about a same rotation center (2), respectively having different sizes and symmetrically arranged in regard to the rotation center (2). Each of the rotating elements (10, 11, 12, 13) is driven by a plurality of actuating elements (30, 31, 32, 33) with a same balance weight, and is pivotally connected by at least one connecting element, so as to form a traction structure symmetrical to each other among the rotating elements (10, 11, 12, 13). The actuating elements (30, 31, 32, 33) and the connecting element can be respectively fitted at interference parts (101, 112) provided on at least parts of the rotating elements (10, 11, 12, 13) to interfere in and absorb the energy from the gravity, therefore, the energy of each actuating element (30, 31, 32, 33) is transferred to respective rotating elements (10, 11, 12, 13) and the connecting element via the interference parts (101, 112), thus the energy is cumulated and transferred. An autorotation device, which can continuously swing and provide a long time view, is formed under the condition of low energy loss. The gravity assisted rotary mechanism (1) is linked with the power generation device (5) to transform the cumulated gravity energy into electrical energy for the use.
