Hydropower facilities using tidal currents and their use in flood control

摘要

The disclosed contents relate to a hydroelectric power plant using tide and tide and a use thereof for flood control. The present invention relates to a water inflow storage facility (10) in which water is flowed and stored; And a second water gate (31) provided at a position in contact with the sea to maintain a water surface that is always lower than the water surface in the water inflow and storage facility (10), temporarily accommodates water flowing from the water inflow and storage facility , An outlet only facility (30) for opening the second water gate (31) at the time of low tide and discharging the accommodated water; And a hydroelectric power generating facility installed between the water inflow and outflow storage facility and the discharge only facility for generating energy by flowing the water stored in the water inflow and outflow storage facility to the downstream by an aquifer, (20). The water-power plant is characterized by the use of the tide. The present invention is superior in that a hydroelectric power generation facility can be provided regardless of the topography.
