Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<First embodiment>

As shown in Figs. 2 and 3, the waterwheel rotary power generation apparatus of the first embodiment includes a motive unit 10, a driven unit 20, a pivot unit 30, a power generation unit 40, and a falling water ( It is composed of a water supply unit 50 to generate electricity by using a drop of water falling from above.

The motive part 10 is composed of a motive roll 12 and a motive shaft 14 for supporting the motive roll 12 to rotate smoothly.

The motive roll 12 is a means for transmitting a rotational force to the driven part 20 due to the falling water provided through the falling water part 50.

In this case, the motive roll 12 is composed of a chain sprocket that facilitates long-distance power transmission.

The motive shaft 14 supports the motive roll 12 so that it rotates smoothly, and both ends are supported by a bearing housing (not shown) fixed to the ground or frame.

The driven part 20 is composed of a driven roll 22 and a driven shaft 14 that supports the driven roll 22 to rotate smoothly.

The driven roll 22 is configured at a position spaced apart from the motive part 10 by a certain distance, and is a means for exerting a rotational force so as to generate electricity as it rotates in connection with the motive part 10.

In this case, the driven roll 22 is composed of a chain sprocket that facilitates long-distance power transmission.

The driven shaft 24 supports the driven roll 22 so that it rotates smoothly, and both ends are supported by a bearing housing (not shown) fixed to the ground or frame.

In addition, the prime mover 12 and the driven roll 22 of the prime mover 10 and the follower 20 are configured in plural to be spaced apart at a predetermined interval, and a turning part 30 is configured between the spacings.

The pivoting part 30 includes a plurality of chains 32 configured to pivot between a plurality of prime mover rolls 12 and driven rolls 22 at regular intervals, and in the longitudinal direction of the plurality of chains 32 It consists of a basket 34 fixed at both ends of the chain 32.

The chain 32 is configured to swing between the prime mover roll 12 and the driven roll 22, and performs a function of transmitting the rotational force of the prime mover 12 to the driven roll 22. In this case, the chain 32 is not limited to the chain, and can be changed according to the structure of the prime mover 12 and the driven roll 22. For example, when the driving roll 12 and the driven roll 22 are composed of a belt pulley, they are composed of a belt.

The basket 34 has a receiving space for storing water falling through the dripping portion 50, and a plurality of the baskets 34 are formed along the chain 32 at regular intervals.

In addition, the end of the basket 34 is formed with an inclined surface 36 downwardly inward, so that the water stored in the basket 34 is concentrated inward, thereby minimizing water loss during movement.

The power generation unit 40 is connected to one side of the driven unit 20, that is, a driven shaft 24 to convert kinetic energy by rotation of the driven unit 20 into electric energy to generate electricity. In this case, since the power generation unit 40 is a general technical idea, specific configurations and operational relationships are omitted.

The falling water part 50 is configured to be spaced apart at a predetermined interval above the motive part 10 so that water is filled in the basket 34 of the turning part 30 located in the motive part 10. In this case, the falling water part 50 is not limited to water, and various fluids may be used depending on the purpose of use and the installation location, such as oil or a gas such as wind, which is a kind of liquid.

Looking at the state of use of the waterwheel rotary power generator configured as described above is as follows.

First, water is dripped downward from the dripping part 50 configured above the motive part 10.

At this time, it is accommodated in any one of a plurality of baskets 34 of the turning part 30 connected to the motive roll 12 of the motive part 10 configured below the falling water part 50.

In addition, water accommodated in the basket 34 is concentrated inward by the inclined surface 35 configured at one end of the basket 34, and when a certain amount of water is filled in the basket 34, its own weight As a result, the basket 34 moves downward.

Subsequently, while the basket 34 located above the basket 34 moving downward is filled with water provided from the dripping water part 50, water is sequentially transferred to the upper basket 34 as described above. As soon as it is filled, kinetic energy moving downward is generated.

In addition, the basket 34 moving downward has the chain 32 fixed at one end, so that the chain 32 moves from the motive part 10 to the driven part 20, By rotating the driven roll 22 of the eastern part 20, and by rotating the driven shaft 24 configured in the driven roll 22, in the end, the power generation unit 40 configured on one side of the driven shaft 24 Electricity is generated through it.

In particular, by being configured to be spaced at a predetermined interval so as to have a linear distance on a vertical line between the motive unit 10 and the driven unit 20, the basket 34 is formed at a linear distance along the vertical line by gravitational acceleration. It accelerates the moving speed.

For this reason, as in the prior art, in the power generation device simply made of a waterwheel type, power generation was made only through a rotational force according to a position change of the rotation radius of the waterwheel, but in the case of the present invention, the motive part 10 and the driven part 20 As the kinetic energy due to the rotation radius of) and the kinetic energy due to the gravitational acceleration due to the spaced linear distance are combined, the rotational force of the driven part is accelerated, so that improved power generation capacity can be obtained under the same conditions.

<Second Example>

The same reference numerals are used for the same configuration as in the first embodiment, and detailed descriptions thereof will be omitted.

The turning part 30 of the second embodiment is a chain 32 configured to swing between the motive part 10 and the driven part 20, and a space configured in the chain 32 and capable of receiving water inside It is composed of the formed basket 34.

In addition, the revolving part 30 includes a structure to accelerate the rotational force by delaying the residence time of water in the basket 34 that moves downward by the water provided from the dripping water part 50, thereby increasing power generation efficiency. Let it improve.

That is, the turning part 30 includes a support plate 31 fixed between a plurality of chains 32, as shown in FIG. 4.

In addition, a fixed housing 36 fixed to one side of the support plate 31 so as to be located at the upper end of the basket 34, and configured at the upper end of the basket 34 and inserted into the fixed housing 36 to be inserted into the basket ( A hinge shaft 38 is configured to support 34) so that it can freely rotate.

In addition, a first fixing shaft 37 fixed to the support plate 31 so as to be located at the lower end of the basket 34, a second fixing shaft 39 configured at one side of the lower end of the basket 34, and the A spring configured between the first and second fixed shafts 37 and 39 to intercept the rotational range when the basket 34 rotates about the hinge shaft 38 at a certain angle and provide an elastic force to return to its original position. It consists of (35).

It looks at the operating state of the turning portion of the waterwheel rotary power generation device configured as described above.

As shown in FIG. 5, when the basket 34 in which water provided through the dripping part 50 is stored reaches the position of the driven roll 22 of the driven part 20, the horizontal line of the driven roll 22 is The basket 34 is maintained in a horizontal state.

And, the basket 34 is gradually moved downward by the rotation radius of the driven roll 22, at this time, the hinge shaft 38 configured at the upper end of the basket 34 is the center of the fixed housing 36 By being configured to rotate at a certain angle, the weight of the water stored in the basket 34 and the weight of the basket 34 itself are rotated to a portion where the force is parallel. Accordingly, the water stored in the basket 34 is not completely drained to the outside and stays in a certain amount, thereby increasing the acceleration of gravity by the load acting on the basket 34.

That is, in the conventional waterwheel type power generation device, water is drained from the rotation angle of the basket after 45° based on the vertical center line of the waterwheel, and when it is located on the horizontal center line of the waterwheel, the water is completely drained from the basket. By doing so, an increase in rotational force cannot be expected.

On the contrary, the present invention maintains a state in which a certain amount of water is retained in the basket 34 moving along the driven roll 22, as shown in FIG. 5, thereby adding an acceleration under the load by the amount of retained water. , The rotational force of the driven roll 22 is increased, and power generation efficiency is improved due to the increase in the rotational force.

What has been described above is only one embodiment for implementing the waterwheel rotary power generation device, and the present invention is not limited to the above embodiment. Those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications can be implemented without departing from the gist of the present invention.
