空胴部９Ｃの外部の適当な位置に船着台１３を設け、空胴部９Ｃ内に人が入るための図示しない入口に扉が設けてあり、人が空胴部９Ｃ内に入って、発電機等の保守点検などができるようになっている。
A landing 13 is provided at an appropriate position outside the cavity 9C, a door is provided at an entrance (not shown) for allowing a person to enter the cavity 9C, a person enters the cavity 9C, and generates electricity. Maintenance inspections of machines etc. can be performed.
潮流は一定の速度で流れており、停止することはないので、風力よりも安定した発電をさせることができる。１本の横長主軸３に複数のロータ６が固定されており、揚力型横長ブレード７は、流れの方向に関わらず回転するので、潮流が低速度で、かつ向きが変っても、大きなトルクが得られ、効率の良い発電をさせることができる。
The tidal current flows at a constant speed and does not stop, so it can generate more stable power than wind power. Since a plurality of rotors 6 are fixed to one horizontal main shaft 3 and the lift type horizontal long blades 7 rotate regardless of the flow direction, a large torque can be obtained even if the current is low and the direction is changed. It is possible to generate power efficiently.
また、１本の横長主軸に複数のロータが固定されており、流速の遅い場所においても、水流による大なトルクで、効率の良い発電をさせることができるので、水路上や水中における発電に広く利用することができる。
In addition, because multiple rotors are fixed to one horizontal main shaft, and efficient torque can be generated with a large torque by the water flow even at locations with low flow velocity, power generation on waterways and in water is widely used. It can be used.
