The above structure allows a turbine having a pumping function to operate in a two-way flow.

Referring to FIG. 1 , FIG. 2 and FIG. 7 , the working principle of the water turbine with water pumping function according to the present invention will be described below:

When the water turbine having the pumping function of the present invention is used as a water turbine, the water turbine having the function of pumping water is placed in a place having a difference in water level, for example, a dam is installed at a suitable place on both sides of the river and the present invention is provided. The water pump with the function of pumping water, or set it in the place where the river and the ocean water flow are rich in energy, when the water flows from the high place or the fast flowing water flows through the water pipe from the water inlet 10, due to the difference between the right side of the water inlet 10 and the water outlet 11 The water blocking device 7 is provided, and the water flow can only flow from the opposite direction to the water blocking device 7. Since the size of the blade 17 matches the size of the inner ring and the outer ring of the water flow passage, the water flow into the turbine having the function of pumping water is made. All are blocked by the blade 17, which can only push the blade 17 of the turbine to rotate the water wheel shaft 4. When the water flow pushes the blade 17 from the water inlet 10 to the water outlet 11, the water flow is discharged from the water outlet 11 to the downstream, and at the same time, the blade The interaction between the blade control lever 13 and the blade opening and closing guide 12 and the blade cylinder 8 gradually form the entire cylinder and pass through the water blocking means 7. Thereafter, the blade 17 is gradually opened with the rotation of the rotor under the interaction of the blade control lever 13 and the blade opening and closing rail, and is fully opened when reaching the position of the water inlet 10, the opening angle is about 90 degrees, the blade control lever 13 and the blade The opening and closing guide rail 12 is separated. At the same time, the other blade opposite to the blade 17 is rotated by the water flow to the water outlet 11, and the two processes alternately complete the above process, thereby pushing the water wheel shaft 4 to continuously rotate to convert the kinetic energy of the water into mechanical energy.

When the water turbine having the pumping function of the present invention is used as a water pump, a water pipe is connected at the water inlet 10, water enters from the water outlet 11, and power (manpower, hydraulic power, etc.) acts on the water pump shaft 4 (when used as a water pump) ), the water pump shaft 4 and the vane 17 are rotated counterclockwise (Fig. 1 - Fig. 9). The blade 17 is fully opened by the interaction between the blade control lever 13 and the blade opening and closing rail 12 at the water outlet 11 and closes the water flow passages of the inner ring and the outer ring, and the axial cross-sectional area of the inner ring and the outer ring is not set by Etc., the areas of the first half leaf 171 and the second half leaf 172 are not equal, and the purpose is that the water flow pressures obtained on both sides of the blade 17 are not equal when the blade 17 is opened, thereby generating a force difference, and the force difference can be The blades 17 are pressed at the

ports

51 and 61 of the inner cylinder 5 and the outer cylinder 6, preventing the blades from being reversed. The water flow is all pushed by the vanes 17 from the water outlet 11 to the water inlet 10. The water is discharged from the water inlet and is pumped out through the water pipe, and then the blade 17 is closed under the interaction of the blade control rod 13 and the blade opening and closing rail 12, and forms a complete cylinder with the blade cylinder 8 to pass the water blocking device. 7. After the blade 17 passes through the water blocking device 7, the blade is gradually interacted with the blade control lever 13 and the blade opening and closing guide 12. When it is opened, it is fully opened when it is turned to the water outlet 11, and the blade control lever 13 is separated from the blade opening and closing rail, so that the water is continuously pumped out from the water inlet.
