PURPOSE: A waterpower generation device which can be easily installed underwater by submerging a barge is provided to use tide vertically and extract a lot of energies by easily installing a tidal current generator on the bottom of a sea using a barge. CONSTITUTION: A waterpower generation device which can be easily installed underwater by submerging a barge is constituted as follows. A bearing case(23) is fixed at the center and bottom of a lower barge(18) in the shape of a diamond. A thrust bearing(25) is fitted into the lower part of a rotary shaft(1) and inserted into the case to stand the rotary shaft. A main blade(3) is formed on the rotary shaft. A buffer stopping device(6) is fixed on the bottom of a partitioned space in order to prevent the blade from being separated from the partitioned space. |
