Claims

[Scope of utility model registration request]

a generator casing in which a generator is housed and installed above a waterway; a rotating shaft having an upper end connected to the generator and a lower part located in flowing water passing through the generator casing and flowing through the waterway; a bearing located above the water surface of the flowing water, interposed between the generator casing and the rotating shaft and receiving the radial load and thrust load applied to the rotating shaft; A plurality of launch blades are attached to the tips of spokes protruding from the shaft and drive and rotate the rotating shaft with the flowing water, and the launch blades are opposed to each other with the launch blades sandwiched in between, and their lower ends are connected to each other, and their upper ends are connected to the A once-through water turbine comprising: a frame-shaped bracket supported by a generator casing; and an underwater bearing interposed between a lower end of the bracket and a lower end of the rotating shaft.
