Abstract

A conventional water turbine comprises blades of fixed length and when the water turbine is in rotation, torques caused by the weight of the blades exactly cancel each other so that the driving force of the water turbine is provided by the blades driven by water flows only. In view of such a condition, the present invention provides a novel water turbine device, which is characterized by comprising length-adjustable blades, whereby when the blades are lifted to move away from the water surface toward an upright position, the blades are acted upon by the gravity to become folded, which shortens the arm of force of the blades, and when the blades pass the upright position, the blades are acted upon by the gravity and expand, increasing the arm of force of the blades. The increased arm of force results in the difference in torques among the blades, which effectively increases the driving force of the water turbine.

Description of the invention (1) '~~ i Background of the invention: I The length of the blades of a traditional water turbine is fixed, so when the water wheel rotates, its blade weight The force and distance caused by the turning car just offset each other. I The thrust of this water wheel is only generated by the blades pushed by the flowing water, that is, the amount of energy it extracts is proportional to the area of the blades under force. If you want to increase the thrust of the water wheel, the supporting structure of the blade must have a relative size to match the displacement of the blade before it leaves the water surface, both of which bear the negative work of drainage. The small blade area cannot be enlarged as the main reason because it cannot capture the power of deeper water. 'For example, the Republic of China Patent: No. 32582 0, a pontoon-type power pump pumping and storing water generator device, the blades of the turbine of the device are in a fixed state, and the blades are driven by the flowing water to drive the turbine, and the blades are rotated With horizontal plane; vertical.

Description of the invention (2) The device is characterized in that the length of the blades can be extended by 1, that is, Each round can be extended to connect it so that it can capture more kinetic energy of flowing water. At the same time, after the blade 轮 leaves enter the water, one side of the blade is subject to the thrust of the flowing water. In order to push the water, this surface forms a resistance. Therefore, when the wheel is more than its resistance, the blade will be in a stretched state. When the force is less than its resistance, the blade will be deflected towards the axis to become zigzag | so the blade is leaving the water during the rising stroke. The thrust force it receives will gradually decrease, and the thrust force on the water 4 will be combined by the gravity of the center of gravity, which will cause the resistance to be greater than the thrust force 5 | The gravitational force shifts towards the sleeve center in a zigzag state | Ye's arm value decreases. ’

Use an appropriate length to increase its working area, because its resistance to squeezing water is reduced, and its blade force arm = will add to the thrust of the water wheel. The operation of the device is described in the column diagram. Fu Zhengyan ‘the depth of the flowing water is the required length.

This figure shows that the blade can be stretched into a straight line I to increase the power distance of the water wheel. 7 sides of each of the blades (5) are provided with a pulley (54), which is in contact with a cam (55), and the cam (55) is connected by a link (9) Let's support two and two = on the body (11), the rotating shaft (1) of the water wheel is supported by the bearing. When the two lambda two water wheel rotates, before the blades (51) approach the level, its pulley (54) The row of blades < one (55) and the thrust of the delta cam (55) accelerates the blades to rise, as shown by the leaves (in), when the blades (56) are displaced beyond the vertical line (57), the wheels Leaf rq ^ M0 / the gravitational force caused by the gravitational pull makes it fall, then it will be linear with the impeller, as shown in the impeller (58), so the impeller can be stretched into a straight line earlier.丨 Figure 6 Schematic diagram of the reduction of the resistance of the blade extension. This figure shows that the resistance of the blade can be reduced when the blade is stretched into a straight line earlier. The blade in the figure is a hollow body, which contains about 3/4 of the liquid. Therefore, when the blade (51) is approaching the cam / 55 (a) at a rising displacement, as shown in the blade (56), the fluid in the body will be displaced, and when the blade (56) exceeds the level, The liquid will be inclined to the other side, so if the center of gravity of the blade (56) is closer to the axis, the rising resistance of the blade (56) will also be reduced, which is conducive to the improvement of the blade (56).
