In addition, since the detailed description of the transmission device and the rotational force transmission device and the like known in the prior art document is omitted, the detailed description of the function or configuration is disclosed in the Republic of Korea Patent Publication No. 10-2004-0033161, Republic of Korea Refer to Patent 10-1050134, Republic of Korea Patent Publication No. 10-2011-0086676, Republic of Korea Patent Registration 10-1037711.

1 is a conceptual diagram of a water flow energy conversion device for converting the water flow energy to the electric energy adopted by the present invention, Figure 2 is a perspective view of the water flow energy conversion device to which the present invention is adopted, showing a water flow energy conversion device to which the present invention is adopted Doing.

As shown in Figure 1 and Figure 2 of the present invention, the water flow energy conversion device 1 of the present invention installed in the sea is a floating body (3) floating on the fluid by buoyancy of the seawater, which is a fluid (2), and Three or more support guides 40 which are installed in the floating body 3 and which support the water column to slide in the longitudinal direction in accordance with the change of the position of the floating body according to the change of the water level, and which are resistant to the force of the fluid flow. Three or more flow columns that act as a column and resist water flow as a whole, including a plurality of water flow vanes 20 that are coupled to the outer side of the central axis 30 having strength and rotated by water flow. (5), and a portion of the upper end is inserted into the support guide 40 of the float (3) is supported to slide in the longitudinal direction to the support guide 40 of the float (3), the end is below the water surface The three or more supported on the ground formed in the The water column 5, the floating body 3, the water column 5, and the ground formed under the water surface form a truss-shaped structure, and the water column 5 which is bent by the force of the water flow is differentiated ( differential) means for straightening the central axis of rotation of the water flow vane 20 and rotational force transmission means for transmitting the rotational force between adjacent differential elements differentiated by the differential means, the central axis 30 of the water column (5) Or an energy conversion device connected to the water flow wing 20 to convert mechanical energy including a rotational force of the central axis or the water flow wing into electrical energy or physical energy.

Here, the meaning of straightening the axis of rotation of the water flow vanes 20 by differentially forming the water flow columns 5 is the same as mathematically differentiating the curves to form straight lines having a constant slope. This means that the unit rotation center axis is closer to the straight line by dividing the entire center of rotation axis of (20) into a straight line having a constant slope.

The differentiating means of the first embodiment of the differentiating means is a plurality of water flow vanes 20 which rotate while sliding relatively slidingly supported by the central shaft 30 formed as a rigid body and supported by the central shaft 30, the rotational force transmission The means may be a rotary transfer hole 27 connecting each water flow wing to be able to bend relatively, as shown in Figs. At this time, it is preferable that two or more rotation transfer holes 27 are inserted into the rotation transfer holes 23 formed in the respective water flow vanes shown in FIG. 5 so as to transmit rotation, and the rotation transfer holes 27 are shown in FIG. 8. As can be stretched as described above, each water flow wing can follow the rotational center axis bent by the water flow and rotate in an inclined state to transmit rotational force.

Meanwhile, in FIG. 2, the rotational force is transmitted through the support guide gear 41 shown in FIG. 10 formed on the outer circumference of the support guide 40. However, the outer diameter of the support guide is large, so that the cost of forming the support guide gear 41 is high. Since it takes a lot, the water flow wing 20 of the portion close to the support guide 40, as the differential means of the second embodiment to be described later as a rigid body so that the central axis 30 and the water flow wing 20 do not rotate relatively Forming, connecting the water flow wing of the lower end adjacent to the water flow wing 20 with the rotary transfer port 27, the central axis 30 of the bottom is connected to the rotary connector 38 so that the rotational force is not transmitted to all the water flow As the rotational force of the blade is transmitted to the upper center shaft 30, and as shown in Figure 6, the rotational transmission gear 45 is installed on the upper central shaft 30 to be axially slidable to transmit the rotational force.

The shaft 30 follows the rotation center axis that is bent by the water flow, and rotates while being inclined with each other, thereby transmitting rotational force. The power connector 31 has a lower support collar 32 formed at the lower end of the shaft insertion hole 33 and the divided central shaft 30 into which the divided central shaft 30 is inserted, as shown in the left figure of FIG. ) And a support collar (39) in which a support collar insertion hole (34) into which the upper support collar (32) formed at the upper end of the divided central shaft (30) is inserted is formed, and the inserted central shaft (30) is not bent from each other. And a rotary joint 37 formed in the support sleeve 39 and a universal joint for rotatably connecting the lower support collar 32 and the upper support collar 32.

At this time, the central axis of the part in contact with the ground is connected to the rotation connector 38, which is relatively rotatable but without bending, as shown in the right drawing of FIG. 7 so that the rotational force is not transmitted to the ground. .

From this configuration, the floating body 3, the three or more water column 5, and the ground 6 formed below the water surface become a structure having rigidity, so that a table having three or more legs is fixed to the ground. It is fixed to the ground (6) formed below the water surface without the support of the, even if the water column (5) is bent in accordance with the movement of the float (3) in accordance with the water flow is a form that differentiates the arc according to the bending, so the center of the linear axis Will rotate.
