Title:
GRAVITY TYPE OF ELECTRIC POWER GENERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/178626
Kind Code:
A1
Abstract:
Provided is a gravity type of electric power generating apparatus, comprising: a main body case; an operating unit; a direction changing unit; and an electric power generating unit. The main body case has a plurality of guide rods that have a predetermined length and are vertically installed therein. The operating unit includes: an upper operating plate assembled to the center of the guide rods so as to be movable up and down; a lower fixed plate secured to the guide rods; and a bellows disposed between the upper operating plate and the lower fixed plate and having an internal space filled with a predetermined amount of air, and the operating unit repeatedly contracts and expands the bellows by a load that is transmitted to the upper operating plate so as to be repeatedly created or dissipated. The direction changing unit includes: a vertically moving member that is connected, at the upper end thereof, to the upper operating plate and passes through the bellows to reciprocate up and down along with the upper operating plate; a spiral groove that is formed on the inner peripheral surface of an insertion hole into which the end portion of the vertically moving member is correspondingly inserted, and allows a guide ball provided on an end portion of the vertically moving member to be guided and moved therethrough; and a rotating member assembled to a rotation support member between the bottom of the main body case and the lower fixed plate so as to be rotatable, and the direction changing unit converts a vertical motion into a rotary motion. The electric power generating unit includes: a rotor having a drive gear engaged with a gear that is formed on the outer peripheral surface of the rotating member; and a stator corresponding to the rotor, and the electric power generating unit generates an induced current.
