[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a water wheel is turned to receive the fallen water by a dish, push it up again with little power, circulate it, drop it again, and turn the water wheel again. This is an extremely efficient hydropower generation system capable of generating electricity from small to large scales, and particularly suitable for small-scale private power generation (about 5 to 100 kW). It is possible to generate 3 to 5 kW / hour by circulating 300 liters of water in the main tank 10 times / day.

[0006] The hydroelectric power generation is usually installed in a river where the water of the river falls naturally and flows more than a certain amount, but the power generation system of the present invention supplies only the natural consumption of water such as evaporation and scattering. Then the water can be continuously circulated. Therefore, it has a feature that it can be installed as appropriate in places other than rivers. The head drop from the main tank level to the turbine level should be at least 3-5
m or more is preferable. The present invention is also characterized in that a liquid other than water can be used.

[0007] The rotational speed of the water turbine is connected to a generator by changing the rotational speed using a transmission gear.

The water in the cylinder is returned to the main water tank through the return pipe. A check valve is provided between the return pipe and the cylinder so that the water accumulated in the return pipe does not flow back into the cylinder. Also, when the tank filled with water descends by its own weight and pushes the water in the cylinder to the return pipe, the pipe connecting the relay tank and the cylinder is also checked so that the water in the cylinder does not flow back to the relay tank. There is a valve.

The capacity of the relay water tank must be at least two tanks when the tank is full. Also, it is necessary that the amount of water for one tank remains even at the minimum.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an explanatory diagram of the power generation system of the present invention. Water falling from the main water tank 1 hits the blades of the water wheel 4 to rotate the water wheel. The rotation of the water turbine is changed to a high-speed rotation by the transmission gear 3 and the generator of the power generator 2 is turned to generate power. The water after turning the water wheel is the saucer 5
And injected into the piston tank or Infusion continues until one of the tanks is full. In this figure, it is injected into the tank. When the tank is full, it sinks under its own weight. The tank is connected to the piston 8, and presses down the piston 8 as the tank sinks to push out water accumulated in the cylinder to the return pipe 9. A check valve is attached to a pipe connecting the cylinder and the return pipe 9 so that water flows only in the direction of the main water tank, and water collected in the pipe does not flow back to the cylinder side. A check valve is also attached to the pipe connecting the cylinder and the relay water tank, so that the water pushed out from the piston does not flow back into the relay water tank. The water in the cylinder is pushed by the piston and flows only in the direction of the return pipe. Thus, the water in the cylinder is returned to the main tank again, and the water falls again.

On the other hand, the piston tank has a shape which is widened with a slope on the side as shown in the figure, and a guide roller is in contact with the slope. Therefore, when the tank sinks down, it is pushed down by the guide roller and falls downward while tilting to the left in the figure, and finally it is inclined to the position shown by the dotted line and the water in the tank is discharged into the relay water tank 7. Becomes

At this time, the inside of the cylinder is in an empty state by pushing out water, and the tank is in an inclined state by discharging water. On the other hand, the piston tank is connected with a rod, and the rod rotates around the fulcrum 6.
Thus, when the tank goes down, the rod rotates clockwise, falls to the right, and the tank goes up. When the tank is tilted and in the dashed line, the tank is lifted up and is in the dashed position.

At this time, the vertical relationship of the tray reversing plate connected to the rod is also reversed, so that the reversing plate comes down and the reversing plate goes up (reverse to the position shown in the figure). That is, as the rod rotates clockwise, the reversing plate moves down the long groove along the pin, while the reversing plate moves up the long groove along the pin. A tray is placed on the tip of the reversing plate, and the tip can slide freely along the inclined surface of the bottom of the tray, so that the position of the bottom of the tray changes according to the movement of the tip. That is, the inclination of the tray changes from the downward right shoulder to the upward right shoulder.

In other words, when the tank is tilted and empty, and when the cylinder is empty, the tank is empty with the tank standing straight at the position indicated by the dotted line, and the tray is in a state of rising to the right so that it can be poured into the tank. When the tank goes down and the tank goes up, the piston of the cylinder goes up together. At this time, the water in the relay water tank 7 is sucked, so that the inside of the cylinder is filled with water.

Here, when the water in the tank, which has been returned to the main water tank, starts falling again, the tank sinks down, and the water is pushed out from the cylinder to the return pipe. As described above, the power generation is continuously performed while the tank and the tank alternately repeat the same process.

Here, since the water in the main water tank and the relay water tank is naturally consumed by evaporation and scattering, it is necessary to provide a float switch and supply water so that the same liquid level can be always maintained.

In the present invention, the force for pushing water out of the cylinder depends on the weight of the water in the piston tank.
If the pressing force is insufficient, another power may be added as an auxiliary.

[0018]

The present invention has the following effects. The water after turning the water wheel can be recycled and used, and there is little recirculation cost. Equipment costs are extremely low. Suitable for small-scale in-house power generation.
