Referring to Figures 3, 5, 7, and 9, the hydropower unit 200 is fixed to the bottom surface of the topography 1 by screwing, and the water flow in the water passage 11 flows along the flow direction L to the hydraulic power. At the time of the power generating device 200, the blades 53 of the partial blade assembly 5 are subjected to the impact of the water flow and rotate around the first axis A (see FIG. 5) in the first rotational direction R1, and are blocked by the second limiting blocks 55. The front side 534 of the blade 53 is made to be perpendicular to the flow direction L to greet the water flow (the upper left blade 53 as shown in Fig. 9). Thereby, the blade 53 can be pushed by the water flow and drive the connecting rod 41 and rotate the rotating assembly 3 around the pivot 23 in a third rotation direction R3.

Referring to Figures 3, 5, 8, and 9, when the blade 53 of another portion of the blade assembly 5 is subjected to a water flow and is rotated about the first axis A (see Figure 5) in the second rotational direction R2, the blade 53 is subjected to the The first limiting block 54 is stopped to make the angle between the blade 53 and the connecting rod 41 120 degrees (the lower blade 53 as shown in FIG. 9) to reduce the rotating component 3 along the third rotating direction R3. The resistance experienced when rotating about the pivot 23. In general, the flow of water in the flow direction L drives the blade assembly 5 to rotate about the pivot 23 in the third rotational direction R3. The assist force is greater than the resistance of the blade assembly 5 when rotating in the third rotational direction. . Therefore, the water flow can smoothly drive the blade assembly 5 of the water turbine 20 and rotate the rotating assembly 3 to enhance the turbine 20 to drive the generator 60 through the transmission mechanism 70 (shown in FIG. 4) (as shown in FIG. 4). The efficiency of running electricity.

In summary, the present invention has a hydro-power generating device for a water turbine. When the front surface 534 of each blade 53 of the water turbine 20 is impacted by the water flow, it will rotate around the first axis A in the first rotational direction R1 until it receives the second limiting block. The stop 55 is such that the front surface 534 of the blade 53 is substantially perpendicular to the flow direction L to greet the flow of water, whereby the flow of the water is pushed and the link rod 41 is driven and the rotary assembly 33 is rotated about the pivot 23 in the third rotational direction R3. When the rotating assembly 3 is rotated to bring the back surface 535 of the blade 53 toward the fluid, the blade 53 is rotated around the first axis A in the second rotational direction R2 until it is blocked by the first limiting block 54 to reduce the force receiving area. This reduces the resistance of the water flow when the turbine 20 rotates, and the efficiency of the turbine 20 to drive the generator 60 to generate electricity is improved, so that the object of the present invention can be achieved. Further, since the water turbine 20 is fixedly connected to the bottom surface of the water channel 11 and is located below the water surface of the water flow, the water turbine 20 is completely flooded by the water flow without occupying the space on the water flow surface. Further, when the water flow in the water passage 11 is swollen by heavy rain, the water turbine 20 is not arbitrarily drifted by the water flow or blocks the water passage 11.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
