The utility model relates to the technical field of power generation equipment, and particularly discloses a gravity power generation ferris wheel device which comprises a rotating wheel support, a rotating wheel
assembly is installed on the rotating wheel support, the rotating wheel
assembly comprises a rotating wheel, a ball falling
pipe is arranged over the rotating wheel, a ball return opening is formed under the rotating wheel, and a plurality of ball grooves are formed in the outer circumference of the rotating wheel. Ball cover assemblies capable of being opened and closed are installed on the ball grooves, a turning cover closing area is formed on the outer circumference of one side of the rotating wheel, a turning cover opening area is formed on the outer circumference of the other side of the rotating wheel, an arc-shaped
handrail is arranged on the turning cover opening area and located between the ball cover assemblies, and a cover pressing wheel is arranged above the end, close to the ball falling
pipe, of the turning cover closing area; the ferris wheel device prevents the floating ball from accidentally falling off, meanwhile, it is guaranteed that when the floating ball falls off from the ball falling
pipe, the situation that the floating ball fails to fall off due to the
closed state can be prevented, the whole structure is relatively simple, the equipment cost is reduced, and operation is smooth and stable.
