Fig. 1 installs and uses schematic representation for the utility model; Fig. 2 is the utility model main impeller structural representation; Fig. 3 is the utility model sub-propeller structural representation.

Embodiment:

Below in conjunction with embodiment, the utility model is done further narration.

Embodiment 1: as shown in Figure 1, the end of aqueduct A (1) leads to the bottom (or bottom) of the eminence water surface (2), the pipeline A the other end leads to fixed base A (3), on fixed base A, longitudinal central axis (4) is arranged by bearing support and bearing fixing, axis is arranged in the pipe tunnel B (5), pipeline B is for fixing, axis is rotatable in pipeline B, near the axis and the pipeline B bottom lower water surface (6), be provided with fixed base B (7), in fixed base B,, on the undersurface axis below the fixed base B, be provided with sub-propeller (8) and main impeller (9) by bearing support and bearing fixing axis, when power demand little or water can hour, main impeller can only be set, when big or water can be big when power demand, sub-propeller and main impeller can be set simultaneously, sub-propeller can be provided with some groups, and present embodiment is provided as two groups; Below main impeller, be provided with fixed base C (10), lower end by bearing support and bearing fixing axis in fixed base C; On the axis above the fixed base A, be provided with electricity generating device (11), by the rotation of axis, drive the rotation of electricity generating device.

As required, sub-propeller and main impeller also can promote and be arranged on the above axis of the water surface.

As shown in Figure 2, top is the plan view of main impeller, the bottom is the front view of main impeller, being configured to of main impeller: whole is cylindric box, axis is positioned at the central authorities of main impeller, and fix with main impeller, the middle part of main impeller is water intake (12), the water inlet is in the top of main impeller, opening upwards, identical with pipeline B bore, and dock with pipeline B, water intake can be set to recessed as required, plane or protruding upward, on the edge of main impeller, be provided with water outlet (13), generally, the gross area of water outlet equates with the gross area of water intake or is close, also can be set to the gross area of the gross area of water outlet less than water intake as required; The opening direction of water outlet is identical with the tangent direction at the edge of main impeller, is communicated with by water channel (14) between water intake and the water outlet; As required, water channel can be set to several, generally can select 2-10, is preferably 3-8, is set to 6 in the present embodiment, and for reducing the resistance that flows of water, water channel can be set to from top to bottom, one section helical arc from the inside to the outside.

As shown in Figure 3, the structure of sub-propeller and main impeller structure are basic identical, and distinctive points is that sub-propeller sets up the baffle plate (15) of ring-type around the water outlet, because the existence of baffle plate can make water be back to the water intake of next sub-propeller (or main impeller) again.After first sub-propeller was set, the water intake of the sub-propeller below first sub-propeller (or main impeller) adopted plane or slightly recessed setting, so that entering through first sub-propeller recirculation water.

Impeller can be provided with the size of its diameter as required, I show by experiment, under the condition of about 25 Kilograms Per Seconds of testing of water flow, the employing diameter is 14 centimetres a impeller, and just can drive object (electricity generating device) diameter is that 40 centimetres of weight are 20 kilograms cylindrical body rotation.

Electricity generating principle of the present utility model is: water enters pipeline B by pipeline A, finally enter the sub-propeller water intake, enter the water intake of main impeller again by the water outlet of sub-propeller, water in sub-propeller and main impeller by water intake by water channel in the water outlet flow process, and water is when water outlet flows out, according to momentum conservation and active force reaction force principle, the water of ejection is under the effect that is subjected to smooth water resistance, produce a kind of reaction force, under the effect of reaction force, the rotation of the axis that has promoted sub-propeller and main impeller and be fixed thereon, axis finally drive the rotation of electricity generating device, thereby realize generating.

Why sub-propeller of the present utility model and main impeller place hydrostatic, are that the reaction force that it produced is twice at least owing to place hydrostatic than placing air.

During use, two kinds of methods are arranged, one, the water that the water power plant is discharged utilizes again, the utility model can be installed on the water orifice place in water power plant, connects by pipeline, electricity generating device is installed on the place of barrage below away from dam, for the water power plant, neither influence the generating of normal main water turbine, can the current of ejection be utilized once more again; Its two, self-built barrage leads to the bottom of barrage with pipeline A of the present utility model, and electricity generating device is installed on barrage below or away from the place on dam, directly utilizes the water of barrage to generate electricity.

Because the active force that the utility model water turbine produces is big, builds the barrage that 20 meters high water level poor (referring to the height difference of high water level face to sub-propeller) are arranged and to realize generating.By the utility model, also the current of waterfall can be used generating.The utility model also can wait as mill to other rotatable thing power is provided, and this moment, electricity generating device was replacements such as mill.
