A power generation device that utilizes gravity and buoyancy, with an external elevating guide equipped with shock absorbing means.

摘要

Disclosed is a power generating apparatus driven by a combination of gravity and buoyancy and having a shock absorbing member in an outer elevation guider. More specifically, in a power generating apparatus driven by a combination of gravity and buoyancy to generate electrical energy, a stopper member and a shock absorbing member are installed to an upper portion of an outer elevation guider, and a shock absorbing spring is installed to a lower portion of the outer elevation guider, so that a repulsive force of an inner elevation part which is moved up by buoyancy of compressed air is absorbed by the shock absorbing member, thereby preventing the outer elevation guider and the inner elevation part from being damaged and thus using the inner elevation part in the outer elevation guider for a long time, without being failed or damaged.
