Description
Technical field
The present invention relates to the pressure water cushion type biscrew hydraulic turbine that a kind of hydroelectric power is used.
Background technique
Present hydroelectric water turbine adopts water bucket type or jet-type or worm-gear type more, these water turbine all are the impulse force works done that utilizes water, so require that the water yield is very big could be moved, usually to set up dam at the scene, invest very high, and the level of resources utilization is lower, makes the development of China's electric power can not satisfy and adapt to the development of modernization paces.”
Summary of the invention
The object of the present invention is to provide a kind of little investment, the press water cushion double-shaft spiral water turbine that the level of resources utilization is high.
Technological scheme of the present invention is: be provided with a hemisphere or columniform fixed wheel and driving wheel, fixed wheel is fixed on the fixed base, coaxial being nested of outer wheel face of the interior wheel face of fixed wheel and driving wheel, have the opposite V-arrangement spiral water flow wire casing of direction at fixed wheel inwall and driving wheel outer wall, the rotating shaft of driving wheel is connected with the rotating shaft of generator, fixed wheel bottom centre is provided with the water intake that communicates with the press water pipeline, and fixed wheel top is provided with bypass channel, and the bypass channel bottom is provided with the water return pipeline that overflow water is discharged to wet pit.Under the effect of pressure flow, make driving wheel realize that reverse acting spiral rotates, and drives the generator rotary electrification.
Spiral water flow wire casing on the fixed wheel by wheel bottom centre ring along ball or the post internal surface spiral that makes progress, driving wheel spiral water flow wire casing by axle center, wheel bottom along ball or the outer surface of column spiral that makes progress.
When fixed wheel and driving wheel were hemisphere, spherical surface and driving wheel ectosphere surface had the opposite V-arrangement spiral water flow wire casing of direction in fixed wheel.
When fixed wheel and driving wheel when being cylindrical, barrel surface and round bottom surface have the opposite V-arrangement spiral water flow wire casing of direction in fixed wheel, driving wheel exterior cylindrical surfaces and round bottom surface also have the opposite V-arrangement spiral water flow wire casing of direction, and the fixed wheel inner cylindrical wall from bottom to top has the V-arrangement spiral water flow line that is connected round bottom portion spiral water flow line with the driving wheel outer cylindrical wall.
Principle of the present invention is:
(1) according to Pascal's law: must equivalently arrive everywhere along liquid transfer to the added pressure of fluid-encapsulated arbitrary part.Can learn water turbine pressure piping sectional area S

0During for certain value, moving water wheels surface area is big more, the pressure F that is then born
2Big more.
(2) by Archimedes' principle: " object suffered buoyancy in fluid equals this object and arranges weight with the volume flow, and the buoyancy direction is constant upwards." when generator amature weight adds driving wheel weight trend and equals buoyancy, the frictional force f on the generator bearing → 0, this moment, driving wheel can convert hydrodynamic pressure to the rotating force distance on to greatest extent.
(3) utilize the corresponding surface of two-wheeled to go up the oppositely bourn acting force and the reaction force of " V " dimorphism helix groove, when fixed wheel restrained when static, the vector of the flow action of driving wheel and driving wheel reverse flow active force is superimposed, generation is to the rotating force distance of driving wheel, when " V " shape helix groove close more, its stressed surface area is big more, and the running torque of generation is just big more.
(4) as can be known, when big more its inertia of quality of driving wheel is big more, the big more moment along driving wheel cylindrical tangent direction of diameter is just big more by the law of inertia.
When pressure equals P
0Fluid when carrying along the two-wheeled gap from fixed wheel and driving wheel bottom centre, fixed wheel bears the lifting that upwards pressure.When pressure fluid flows out along fixed wheel " V " the shape helix groove of driving wheel spiral water flow " V " shape wire casing and reverse acting spiral, produce running torque, to the generator transmitting torque, drive the generator set generating by rotating shaft to driving wheel.
The water turbine of this structure utilizes Pascal's hydraulic principle, the water flow pressure that driving wheel bottom is born by on two wheel interfaces on the contrary to spiral water flow " V " shape wire casing be transformed into rotating force efficiently and generate electricity apart from drive the vertical type generator group with this, it is efficient, energy-conservation, water saving, easy for installation; This water turbine need not to set up at the scene dam, so investment is little, level of resources utilization height is applicable to the region of lack of water; Also can utilize existing elevated reservoir to improve electric motor power, resource is fully used.
