  In the drum-type water turbine power generation device 1 of this conventional example, the electric power to be generated is increased by amplifying the rotational force and torque by adding the drum-type water turbine 3 or expanding the width of the drum-type water turbine 3. However, in the structure of the drum type water turbine 3, the amount of power generation is limited.

  Therefore, in the drum-type water turbine power generation device 1 in the conventional example, it is possible to perform more efficient power generation and increase the power generation amount by improving the structure of the water wheel and the shape of the blades provided in the water wheel. Has a problem that must be.

The gist of the present invention for solving the problems of the conventional example is a power generation device moored in a river or an irrigation channel and generating power by rotating a water turbine with a flow of water. A floating hull, a plurality of water wheels provided on both sides of the hull, an axle rotating through the center of the water wheel and rotating with the rotation of the water wheel, and a gear connected to the axle to transmit the rotation; A shaft connected to the gear to transmit the rotation; and a generator to which the shaft is connected and the rotation is transmitted to generate power. The water turbine is provided outside the cylinder and the cylinder. A disk-shaped outer frame with a diameter larger than the diameter of the cylinder, a disk-shaped inner frame with a diameter larger than the diameter of the cylinder, which is provided inside the cylinder, and an outer peripheral surface of the cylinder Eight or a plurality of sheets that are provided and arranged from the outer frame to the inner frame And a root, the the vane, bent portion which is bent perpendicularly to the receiving surface of the blade is formed, the bent portion, the center line of the blade, the bent portion The angle between the bent line when formed is in the range of 30 to 45 degrees, and the presence of the bent part provides a triangular gap through which water flows through the central part of the blade. It is.

According to the power generation device of the present invention, the water flow that presses against the receiving surface of the blade rises and presses the inside of the bent portion (the side continuous with the receiving surface), that is, the water flow is folded not only on the receiving surface. Since the curved portion is also pushed together, as a result, the pressing force of the water flow increases, and the torque and rotational force are amplified.
At that time, the water flow that flows out through the gap pushes the receiving surface of the other blades located behind and the bent portion, and further increases the pressing force and the rotational force, thereby generating more electric power. There is an excellent effect that increases.

(B) It is explanatory drawing of the structure of the blade | wing 16. FIG. It is a side view showing roughly power generator 11 concerning the present invention.

It is a side view of the drum type water turbine power generator 1 concerning a prior art example. It is explanatory drawing which shows the operation state of the drum-type watermill generator 1 which concerns on a prior art example.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. For ease of understanding, portions corresponding to the conventional example will be described with the same reference numerals as the conventional example.

  First, in FIG.1 and FIG.3, the code | symbol 11 shows an electric power generating apparatus, and this electric power generating apparatus 11 is the hull 2 which floats on flowing water, the water turbine 12 provided in multiple pairs on both sides of the hull 2, and the center part of the water wheel 12. An axle 4 that rotates along with the rotation of the water wheel 12 through a shaft, a gear 5a that is connected to the axle 4 and transmits the rotation, a shaft 6 that is connected to the gear 5a and transmits the rotation, and a shaft 6 It is comprised from the generator 7 which connects and the rotation is transmitted and generates electric power.

  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.

  The water wheel 12 includes a drum-shaped cylinder 14, a disk-shaped outer frame 13 having a diameter larger than the diameter of the cylinder 14, and a cylinder 14 provided on the inner side of the cylinder 14. A disc-shaped inner frame 15 having a diameter larger than the diameter of 14, and eight (or a plurality) blades provided on the outer peripheral surface 14 a of the cylindrical body 14 and arranged from the outer frame 13 to the inner frame 15. 16.

  As shown in FIGS. 2 (a) and 2 (b), the blades 16 are perpendicular to each other along the center line CL of the outer frame 13 and the inner frame 15 with an angle θ of 30 to 45 degrees on each side. A bent portion 17 is formed in a bent state on the water flow receiving surface 16a side.

  Due to the presence of the bent portion 17, a triangular gap portion 18 through which a water flow passes through the central portion of the blade 16 is provided.

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

  The gear 5 a is connected to the axle 4 and plays a role of transmitting the rotation to the shaft 6 by changing its direction.

  The shaft 6 is connected to the gear 5 a to transmit the rotation, and also serves to transmit the rotation from the gear 5 a to the generator 7.

  The generator 7 is connected to the shaft 6 and plays the role of generating electric power when its rotation is transmitted. Unlike the conventional example, only one generator 7 is provided to improve power generation efficiency.

  In the power generation device 11 configured as described above, the water flow pressed against the receiving surface 16a of the blade 16 rises and pushes the inner side of the bent portion 17 (the side continuous with the receiving surface 16a). Since not only the receiving surface 16a but also the bent portion 17 is pushed together, as a result, the pressing force of the water flow increases and the torque and the rotational force are amplified.

  At that time, the water flow that has flowed out through the gap 18 pushes the receiving surface 16a of the other blade 16 located behind and the inside of the bent portion 17 (the side continuous with the receiving surface 16a). As the pressure and the rotational force increase, the amount of electric power generated further increases. In addition, the code | symbol WL (water-line) in FIG.3 and FIG.4 shows a water line. Moreover, the arrow B in FIG.1 and FIG.3 shows a water flow direction, and the arrow C shows the rotation direction of the water turbine 12. FIG.

  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. 7).
