  First, in FIG. 1 to FIG. 3, reference numeral 11 denotes a power generation device. The power generation device 11 includes a hull 2 that floats on running water, a drum-type turbine 12 provided on both sides of the hull 2, and a drum-type turbine 12.

  The hull 2 is formed in a ship shape or a bowl shape, moored in a river or an irrigation canal, etc. and floated on the running water.

  As shown in FIGS. 4 and 5, the drum-type water turbine 12 includes a drum-shaped cylinder body 14 and a plurality of blades 15 provided on the cylinder body 14.

As shown in FIG. 5, the blade 15 is formed in a substantially L shape, and includes one blade 15 a provided along the outer peripheral portion 14 a and the one side portion 14 b of the cylindrical body 14, and the cylindrical body 14. A pair of blades 15 is formed by the other blade 15b provided along the outer peripheral portion 14a and the other side portion 14c, and a gap 16 is provided between the one blade 15a and the other side portion 14c. ing.
A plurality of pairs (eight pairs in FIG. 4) of the pair of blades 15 are provided at predetermined intervals.
In addition, the code | symbol 25 in FIG.4 and FIG.5 shows the shaft hole provided in the cylinder 14. FIG.

Further, the blades 15 (one blade 15a and the other blade 15b) are bent in the state where the water flow (see arrow B) is bent along the edge portion at a position separated from the cylindrical body 14. Is formed (see FIG. 5).
Due to the presence of the bent portion 17, the water flow hits the bent portion 17 and the pressing force increases, and as a result, the torque and rotational force of the drum-shaped water turbine 12 are amplified.

  The axle 4 passes through the central portion of the drum-type water turbine 12, rotates with the rotation of the drum-type water turbine 12, and transmits the rotation of the drum-type water turbine 12 to the first gear 5a.

  The first gear 5a is connected to the axle 4 and serves to transmit the rotation to the first shaft 6a by changing its direction.

  The end of the first shaft 6a is connected to the transmission 13 and its rotation is transmitted.

  The transmission 13 is connected to the end of the first shaft 6a to change the rotation speed ratio, and transmits the rotation from the transmission 13 to the generator 7 via the second shaft 6b. .

  The generator 7 is connected to the end of the second shaft 6b, and the rotation of the generator 7 is transmitted to generate power. Unlike the conventional example, only one generator 7 is provided to improve power generation efficiency.

As shown in FIG. 6, the screw-type water turbine 21 has four (or a plurality of) blade pieces 23 along the central portion 22 at the center.
As for the blade | wing piece 23, the outer edge 24 is bent in the receiving surface side of a water flow (refer arrow B). The water flow hits the bent edge 24 to increase the pressing force, and as a result, the torque and rotational force of the screw type turbine 21 are amplified.

  The screw-type water turbine 21 is connected to the long third shaft 6c, and the end of the third shaft 6c is connected to the second gear 5b to transmit the rotation.

As shown in FIG. 3, the ship bottom 2b of the hull 2 is formed with an inclined portion 20 having a required inclination angle from the center portion 2c to the stern 2a side. Thus, the front part of the screw-type water turbine 21 is opened by forming the inclined portion 20 on the ship bottom 2b.
Accordingly, since the water flow flowing through the open portion, in other words, the water flow flowing along the inclined portion 20 hits the front surface of the screw-type water turbine 21, the pressing force increases, and as a result, the torque and rotation of the screw-type water turbine 21 are increased. The power is amplified.

  Further, as shown in FIG. 3, wall-like side portions 19 are provided on both sides of the inclined portion 20. Due to the presence of the side portion 19, the water flow flowing through the inclined portion 20 does not flow in both directions of the ship bottom 2 b but concentrates on the front surface of the screw-type water turbine 21, and as a result, the pressing force of the screw-type water turbine 21 further increases. To do.

Since the generator is used at the same time to generate power, the amount of power generation increases and more efficient power generation becomes possible.
In addition, the arrow B in FIGS. 1-3 shows the water flow direction.
Moreover, it is also possible to generate electric power with a generator by selectively using either one of the drum type turbine 12 and the screw type turbine 21.

  As described in the conventional example, the power generated in this manner is sent to the support column 8 standing on the land by the power transmission line 9 and further from the power transmission line 9 to the predetermined power supply facility via the external power transmission line 10. Is supplied with power (see FIG. 10).
