System for cyclically generating power by utilizing gravitational energy

A system for cyclically generating power by utilizing gravitational energy comprises a first power generation system body and a second power generation system body which are the same in structure, wherein the first power generation system body and the second power generation system body are connected with each other through a first belt conveyor and a second belt conveyor which are obliquely arranged. The first/second power generation system body comprises a gravitational energy machine, a mounting seat, a coupling, a transmission and a generator; the gravitational energy machine comprises a rotating shaft and a rotating device, the rotating device is installed on the rotating shaft, hoppers are evenly and movably connected to the periphery of the rotating device, the hoppers are connected with the spokes through installing shafts, material pouring rods are arranged at the bottom ends of the hoppers, and a material pouring device for triggering the material pouring rods is arranged on the installing base; the
