PURPOSE:To make water flow always in one and the same direction in a water introduction chamber, by disposing check-valves in water inlet and outlet ports, respectively. CONSTITUTION:Upon low tide, water from a lake flows into a water introduction chamber 3 through a water inlet port 4B formed in the upper section, then flows down through a barrel chamber 12, and is discharged to the sea through a water outlet port 6A formed in the lower section. Upon high tide, water from the sea flows into the introduction chamber 3 through a water inlet port 4A, then flows down through the introduction chamber 3, and is discharged to the lake through a water outlet port 6B. A hydraulic turbine 8 of a generator 10 is rotated in one direction by water stream flowing down through the water introduction chamber 3. |
