DETAILED DESCRIPTION OF THE INVENTION In order to more fully and clearly disclose the technical means of the present invention and the effects achievable thereby, the present invention will be described in detail below in conjunction with the accompanying drawings and symbols disclosed.

(First embodiment)
Please refer to FIGS. FIG. 1 is a perspective view showing a hydraulic power generator according to a first embodiment of the invention. FIG. 2 is an explanatory diagram of the operation of the hydraulic power generator according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the hydraulic power generator 10 according to the first embodiment of the present invention includes at least one pair of fans 11, one transmission shaft 14, one pair of universal joints 15 and 17, It consists of one long rod 16, one short rod 161, one joint bearing 18, one transmission case 20, one connector 21, and one generator 22. Become.

Each fan 11 has one coupling portion 12 respectively. Three blades 13 extend from the outer surface of the connecting portion 12 in the direction of rotation. All the joints 12 are fitted on the transmission shaft 14, and the transmission shaft 14 is connected in series with a set of fans 11 so that they can rotate in the same direction. The universal joint 15 is connected to the long rod 16 and the transmission shaft 14, and the universal joint 17 is connected to the long rod 16 and the short rod 161, so that the set of universal joints 15, 17 are used as joints to connect the transmission shaft 14, the long rod 16 and the short rod 161 to each other. The transmission case 20 described above is also called a gearbox. Axial rods (not numbered, but see FIG. 4) extend from both sides of the gearbox. Two shaft rods have a predetermined ratio and are used as the import shaft and the output shaft respectively.

The import shaft is connected with the short rod 161 via the joint bearing 18 . The output shaft is connected to one shaft 23 of generator 22 via connector 21 . The generator 22 is connected with at least one electric wire 24 .

In actual use, since the horizontal connection relationship is maintained from the generator 22 to the universal joint 17, the connector 21, the transmission case 20, the joint bearing 18 and the short rod 161 are maintained in a straight state. The elongated rod 16 is slanted and forms an obtuse angle with the transmission shaft 14. The transmission shaft 14 is substantially parallel to the shaft 23 of the generator 22, and the fans 11 of the group have the same transmission shaft 14. It does not adversely affect rotating in any direction. Thus, the transmission case 20 can receive the torque of the transmission shaft 14 via the long rods 16 and the short rods 161 and change the magnitude or speed of the torque of the transmission shaft 14 . At the same time, the generator 22 converts the kinetic energy of the transmission shaft 14 into electrical energy and outputs it to the outside through the electric wire 24 .

The set of fans 11 floats in a conduit (not shown), thus preventing adverse effects on the inherent irrigation and drainage function of the conduit. In addition, since the fans 11 of this group generate a large torque, the power generation efficiency of the generator 22 can be increased, and the power supply capacity can be improved. In addition, the small-sized hydroelectric generator 10 has advantages of reducing investment costs and generating electricity while preventing environmental damage.

A set of floats 27 are connected in series with the transmission shaft 14 . The transmission shaft 14 can roll smoothly in the liquid flowing through the float 27 . In other embodiments, it is within the scope of the invention for hydroelectric power plant 10 to have at least one float 27 .

Next, the length of the pair of tracks 32 is greater than the length of the main case 30 . The main case 30 is arranged and fixed to one end of the two tracks 32 .

One sub-case 31 is attached to the other end of the pair of tracks 32 and can reciprocate with respect to the main case 30 . The sub-case 31 is connected to the transmission shaft 14 via a universal joint 25 and one connecting bar 26 . In other words, both ends of the transmission shaft 14 are connected with the elongated rod 16 and the connecting bar 26 respectively.

For example, the hydroelectric power plant 10 described above is moved near a ditch 40 and two tracks 32 are fixed to the top surfaces 42 of the two walls 41 of the ditch 40 . When the sub-case 31 approaches the main case 30 in the longitudinal direction of the track 32 by a manual method, an electric method, or an automatic method to reduce the distance between the two, the transmission shaft 14 and the associated assembly are moved by the elongated rod 16 and the connection bar 26. It sinks under the liquid surface 43 while supporting the fan 11 of .

The arrows in FIG. 4 represent flow directions 44 . Liquid in the ditch 40 (which is generally running water) hits the vanes 13 . Since the transmission shaft 14 and the coupling portion 12 are connected, the fans 11 of the set rotate the transmission shaft 14 in the same direction. The connection bar 26 idles with respect to the subcase 31 and does not operate. The transmission case 20 changes the torque of the transmission shaft 14 based on a predetermined value or gear ratio, synchronously operates the shaft 23 , generates electric power with the generator 22 , and outputs the electric power to the outside through the electric wire 24 .

Even if the set of fans 11 in the straightened state is suspended above the liquid surface 43 and the liquid in the ditch 40 continues to flow in the flow direction 44 of FIG.

In the second embodiment, the main case 30 is formed with an elongated hole (not shown) through which the elongated rod 16 can swing so that the sub-case 31 can smoothly reciprocate. is preferred.
