Description

More particularly, the present invention relates to a hydroelectric generator that is suitable for further improving power generation efficiency.

In the top turbine type hydroelectric power generation system, water is dropped from above to rotate the turbine, and power is generated by the driving force of the rotating turbine. Therefore, in order to obtain large power generation energy, a water turbine having a larger diameter is required. In addition, it is made of wood and is expensive and heavy, so it is inefficient, and has become a barrier when considering practical use as a household or small-scale hydroelectric generator using tap water.

That is, when considering a configuration that can be applied to ordinary households by using a small hydroelectric generator, it is necessary to solve both the miniaturization of the entire apparatus and the improvement of power generation efficiency at the same time.
For that purpose, double power generation by the upper part and the lower part is possible by changing the power generation system by rotating the chain belt from the top-wheel type hydropower generation system so that the entire device can be downsized and more energy can be obtained. Become.
Conventionally, as shown in Patent Document 1, for example, a power generation system based on the rotation of a chain belt using buoyancy using bubbles obtained by the self-pressure of water has been proposed.

Patent Publication 2010-275992

According to the disclosed technology of Patent Document 1, it is possible to simultaneously realize both downsizing of the entire device and improvement of power generation efficiency by combining two forces of water gravity and bubble buoyancy. Since the lower part is in the water, it is difficult to generate electricity in the lower part, and there are drawbacks of creating a water tank and a lower tank.

However, according to the disclosed technique of Patent Document 1, it is possible to realize both downsizing of the entire device and improvement of power generation efficiency at the same time by combining the two forces of water gravity and bubble buoyancy. However, since the lower part is in the water, it is difficult to generate electricity in the lower part, and it is necessary to make a water tank and a lower tank.

Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to reduce the energy of falling water by reducing the size of the entire device and improving the power generation efficiency, particularly by the upper part and the lower part. It is to provide a hydroelectric power generation apparatus that can realize both of them simultaneously by incorporating double power generation.

In order to solve the above-described problems, the hydroelectric power generation apparatus according to the present invention is provided up and down by a transport chain and a transport belt in the air without the water supply means for supplying the water to the water tank and the lowermost part. A generator chain or bicycle rim that is connected to a rotation chain of at least one of the gears and that generates power in accordance with the rotation of each of the gears. Electricity is generated by a hub dynamo with a pad.

In the transport chain, water is dropped from the top to a plurality of containers provided at predetermined intervals by dropping water in the circulating movement direction, and the upper gear or bicycle By circulating and moving between the hub dynamo with rim and the lower gear and the bicycle rim dynamo, the gear and the bicycle dynamo for bicycle are rotated to generate double power generation by the upper part and the lower part.

According to the present invention having the above-described configuration, a pair of upper gear and lower gear provided up and down by a conveying chain and a conveying belt in the air without the water tank and the bubble supplying means for supplying bubbles to the lowermost part. By rotating the transport chain and belt that are looped between them and at least one of the above gears, the entire system can be downsized and power generation efficiency can be improved. It can be realized at the same time.

Further, by eliminating the bubble supply means for supplying bubbles to the water tank or the lowermost part, natural energy power generation with low power generation efficiency can be achieved.

It is a figure which shows the structural example of the hub dynamo with a bicycle rim and the bicycle rim dynamo of the hydroelectric generator to which this invention is applied. It is a figure for demonstrating the structure of the electric power generation by two places, the upper gear part and the lower gear part in the hydroelectric generator to which this invention is applied.

Hereinafter, a hydroelectric generator to which the present invention is applied will be described in detail with reference to the drawings.

FIG. 1 shows a configuration example of a hydroelectric generator 1 to which the present invention is applied. The hydroelectric generator 1 generates power using potential energy when water supplied from the supply pipe 2 falls from the upper cup 3a to the lowermost cup 3b. The hydroelectric generator 1 includes an upper bicycle hub dynamo 7a and an upper bicycle hub dynamo 7a that are looped between a pair of rim 5 with a bicycle hub dynamo and a rim dynamo 6 with a pulley for a bicycle. A rim dynamo 7b with a lower bicycle pulley and a plurality of containers 3 provided on the conveyor belt 8 are provided.

In FIG. 1, a rim 5 with a bicycle hub dynamo is attached to the upper part, and a rim dynamo 6 with a bicycle pulley is attached to the lower part so that a water drop of 1.5 m can be obtained. The size of the rim 5 with the hub dynamo for the upper bicycle and the rim dynamo 6 with the pulley for the lower bicycle was set to 1/5. Thus, when the rim 5 with the hub dynamo for the upper bicycle makes one rotation, the rim dynamo 6 with the pulley for the lower bicycle makes five rotations. The belt 8 used a thin plastic hose, and the water receiving cup 3 was made by cutting the bottom of the plastic bottle so that 80 cc of water could enter. Twenty-six water receiving cups 3 were attached to the vinyl hose belt 8 at intervals of 15 cm. The upper hub dynamo 7a was provided with a 6w 2.5w bicycle LED light 10a, and the lower rim dynamo 7b was also provided with a 6v 2.5w bicycle LED light 10b.

The lower rim dynamo 6 with the bicycle pulley was attached so that the vinyl hose belt 8 with the water receiving cup 3 attached was perpendicular to the upper rim 5 with the hub dynamo for the bicycle so that the water force was applied directly below. .
When tap water was put into the cup 3a and pushed down from a height of 1.5 m, it began to move slowly, and eventually it turned faster and the upper LED light 10a and the lower LED light 10b were turned on.

In this device, the upper and lower pulleys may have the same size, but since the falling speed of water is fast, it is better not only to top the pipe but also to supply water by piping 9 from the side in the vertical direction. If the height is high, it is better to supply water from the side.

FIG. 2 shows a configuration example of the hydroelectric generator 11 to which the present invention is applied. The hydroelectric generator 11 generates power using potential energy when water supplied from the supply pipe 12 falls from the upper cup 13a to the lowermost cup 13b. The hydroelectric generator 11 is connected to a transporting chain 19 that is looped between a pair of upper and lower gears 15 and 16 provided at the top and bottom, and a rotation shaft of at least one of the gears. A generator that generates electric power according to the rotation of the conveyor, and a plurality of cups 13 provided at predetermined intervals so as to be the bottom surface in the circulating movement direction of the conveyor chain 19, and the conveyor chain 19 includes: Since the sizes of the upper gear 15 and the lower gear 16 are the same, the water fall speed is fast. Therefore, it is preferable that the water supply pipe 14 can supply water in the vertical direction from the side as well as the top. In addition, when the height is high, the water supply from the side is the same. Based on the gravity of the water supplied to the container by the water supply means, the power is circulated between the upper gear 15 and the lower gear 16, thereby generating double power generation by the upper part and the lower part.
