FIG. 28 and FIG. 29 show another example of a water conserving power generation system that uses the flow energy of water flowing in waterways and rivers in the same manner as in rural areas. 28 is a plan view of FIG. 29, and FIG. 29 is a cross-sectional view taken along line HH of FIG. Reference numeral 400 denotes a water channel, and the water channel 400 can be constructed in the middle of a newly provided one or an old water channel. At the end of the water channel 400, a circular water channel 401 having a large circular shape with a diameter of several tens of meters is formed in a continuous shape with a width of 1 to 3 or 5 m, and a part of the bottom hole 402 comes out to the outside. The entire water channel is configured by communicating the outlet water channel 403. Further, in the center of the circle water channel 401, a fixed shaft 405 is erected via a foundation 404, and a rotating body 406 is supported around the shaft, and a main arm 407 is extended around the outer periphery thereof so as to extend in all directions. It is .

A rotating ring 409 is attached to the outer end of the main arm 407, and turbine blades 411... Are provided in a lower part via the ring 409 via a plurality of lower stays 410 to rotate in the circle water channel 401. It is supposed to be. As shown in the lower right column of FIG. 28, a rubber seal 412 is attached to the outer edge of the blade 411 so that water does not easily escape in the circle water channel 401 and the blade 411 does not interfere with the water channel 401. A suspension wire 413 is attached and supported at the upper end of a wire receiving plate 414 rotatably supported by a bearing at the upper end of the fixed shaft 405. A driving wheel 415 is attached to the lower side of the rotating body 406 of the fixed shaft 405, and a generator 418 is configured to be freely driven through a conduction unit 417 that is hung between the driving wheel 415 and the driven wheel 416. The whole of the fixed shaft 405 and the like can be installed in an inclined posture according to the inclined surface that is lowered in the direction of the arrow S in FIG. 28 and can be configured to effectively apply the flow energy of water that maintains momentum to the blades 411 .

When the water flowing from the water channel 400 enters the circle water channel 401 in the tangential direction as indicated by the arrow P in FIG. 28, the water turbine blades 411 are driven to rotate the entire water turbine in the direction of the arrow R. If it is left as it is, it stays in the circle water channel 401, and is extracted from the bottom hole 402 to the outlet water channel 403. Electricity can be generated by rotating the entire turbine. Reference numeral 419 denotes a reinforcing frame that reinforces and constructs the main arm 407 .

In such a power generator, the circle water channel 401 includes a main body a that is U-shaped (may be V-shaped or square-shaped) and has a short arc shape, except for portions corresponding to the water inlet and outlet, and both ends thereof. It is comprised by joining of the joining type groove unit 421 which consists of the joining flange b provided in this. The groove unit 421 can be integrally formed of FRP, concrete, wood, vinyl resin, or the like .

In order to reduce the bending of the main arm 407, as shown in FIG. 29, a circular auxiliary groove 423 may be provided to float the float 424 from the arm 407 to obtain buoyancy.
In addition, a roller 426 that travels on a circle-shaped guide rail 425 can be provided and supported on the main arm 407. In this case, the roller 426 may be run and supported along the upper edge of the circle water channel 401.
Further, as shown in the upper right column of FIG. 28, the water turbine blade 411 may be a sphere (including a spherical shell) 427, or may be a hemisphere 428 or a spherical shell shape as shown in the right column. .

30 and 31 show an embodiment of a water turbine type power generation device in a river 430. FIG.
The apparatus is installed in a water level following manner through a square fixed column 431 perpendicular to the river 430. Fixed post 431 is fixed extending higher by a This attaching stopped under the flange 434 by an anchor 435 with plugs into pile 433 of base blocks 432 embedded fixed to the center between the width of the river 430. As shown by phantom lines in FIG. 30, the fixed column 431 is swung from four directions by a checker wire 436 whose one end is fixed to the bank side so as not to swing .

A square cylinder-shaped elevating guide cylinder 437 can be moved up and down around the support column 431 without rotating, and the outer circumference of the guide cylinder 437 has an inner circumference that matches the guide cylinder 437 and an outer circumference that is cylindrical. A middle cylinder 438 formed as a surface is provided so as to move up and down together with the guide cylinder 437.
A flange 438a protrudes from the outer periphery of the upper and lower ends of the middle cylinder 438, and an outer cylinder 439 whose inner and outer circumferential surfaces are cylindrical surfaces is disposed on the outer circumference of the middle cylinder 438 corresponding to the gap between both flanges 438a. It is provided so as to be rotatable with respect to 438 .

On the outer periphery of the outer cylinder 439, a main arm 440 is provided extending in all directions, and a drive wheel 441 is provided. A ring 442 is attached via the outer peripheral end of the main arm 440, and a turbine blade 445 with a rubber seal 444 is attached via a plurality of stays 443 suspended from the ring 442. Floats 446 are arranged on the inside and outside, float on the water surface of the river, and are rotatable in a circle water channel 447 of a water level following type .

From the flange 438a, a pedestal 448 is provided so as not to rotate and can be moved up and down. A generator 449 is installed on the pedestal 448 and a driven wheel 450 is provided below the generator 449. The conductive member 451 hung between 441 and 441 transmits the rotation while moving up and down. Reference numeral 452 denotes a guide guide plate that collects the water flow of the river 430 and is connected and fixed so as to guide the river water tangentially to the recessed inlet 453 upstream of the circle water channel 447. An outlet 454 is formed in a recessed shape on the downstream side of the circle water channel 447. Incidentally, reference numeral 455 denotes a lower limit stopper, and reference numeral 456 denotes a rotation-preventing wire, which restricts the circle water channel 447 from rotating by pulling the circle water channel 447 from the bank side .

The river water is collected by the guide guide plate 452 and flows into the circle water channel 447 as shown by an arrow G in FIG. These waters are discharged through the outlet 454 after rotationally driving the water wheel blades 445 in the circle water channel 447. The main arm 440 is rotated by the rotation of the water turbine blade 445 and the outer cylinder 439 is also rotated. When the outer cylinder 439 rotates, the drive wheel 441 rotates and the driven wheel 450 is rotated via the conductive member 451 to drive the generator 449 .

When the water level of the river fluctuates, the circle water channel 447 is moved up and down by the float 446, and this moves the outer cylinder 439 up and down through the water wheel blades 445. During this time, the outer cylinder 439 rotates, so that the outer peripheral drive wheel 441 also rotates while moving up and down. The outer cylinder 439 moves up and down in preparation for the fixed column 431 via the middle cylinder 438 and the lifting guide cylinder 437. Since the cradle 448 protrudes from the middle cylinder 438 that does not rotate but only moves up and down, it only moves up and down while maintaining the state shown in FIG. 31, and thus the driven wheel 450 maintains the same height as the drive wheel 441. Power generation is possible by transmitting rotational motion .

Incidentally, the water wheel blades 445 may be provided obliquely so as to guide the flow of the introduced water as close to the outer periphery as possible, as indicated by phantom lines in FIG.
Further, when the amount of water in the river increases drastically due to flooding or the like, the apparatus may be lifted and retracted by a lifting device 459 driven by a handle 458, as indicated by a virtual line in FIG .
