POWER GENERATING SYSTEM USING DRAINAGE OF BUILDING

摘要

PURPOSE: A power generating system is provided to generate power using the head of water drained from a building or an apartment. CONSTITUTION: A power generating system comprises a drainpipes(14,16) guiding drained water from each floor of a building; a drainpipe making water fall downward; a turbine rotated by making water fall in the lower portion of the drainpipe; a generator generating power by the rotation of the turbine; and a battery storing power from the generator. An intermediate water collecting reservoir(20) is installed between the drainpipes(14,16) to temporarily drain water. The intermediate water collecting reservoir consists of a floating(22) and an opening cover(24). The floating and the opening cover are connected by a connecting member(26). When the floating ascends with the increase of water, the opening cover is separated from the entrance of the drainpipe(16) to open the drainpipe(16). Thus, the turbine is rotated by water from the drainpipe(16).
