PURPOSE:To attain a stable power supply source utilizing a small-sized water current by a construction wherein rotaty blades are rotated with water passing through an outer tube, and this rotation of the rotary blades is transmitted via speed-up gears to a generator water-tightly built in the outer tube. CONSTITUTION:Inlet side stationary guide blades 3 and outlet side stationary guide blades 6 fixedly provided with a bracket 5 and a generator chamber 7, respectively, are fised in an outer tube 1 which includes at its inlet portion a conical opening 4 for collecting current water. Rotary blades 2 rotatably fitted to a shaft 12 through bearings 10 are disposed between the inlet and outlet side stationary guide blads 3 and 6. Acceleration gears 11 is coupled to the distal end of the shaft 12, and a generator 8 is connected to the final step of the speed-up gears 11. |
