Abstract
The utility model relates to a vertical single-phase alternating-current permanent magnetic water turbine-generator which is composed of bearing covers, an upper and a lower covers, rolling bearings, thrust bearings, stators, a water turbine casing, a connecting rod, a water turbine assembled by a flywheel and blades as integration and rotors which are arranged uniformly along the axial direction on the cylinder surface of the rotor shaft by long bar shape permanent magnets. As long as the water head is 10 meters high and the water stream is 5-12 millimeters thick, the generator generates electricity of 100-250 watts, and the utility model is suitable for a dispersed single farmer family which lacks water and electricity in a mountain area.
Description
The utility model relates to the hydraulic turbine generator in the synchronous alternating-current generator, is a kind of vertical single-phase AC permanent-magnet generator of miniature multi-pole type, and the rural households that are specially adapted to the few electricity of mountain area lack of water use.
At present, global generated energy almost all is by alternator, and wherein the overwhelming majority is that steam turbine generator and hydraulic turbine generator send.In sixties end in this century, the hydraulic turbine generator single-machine capacity has reached 500,000 kilowatts in the world.Existing large-scale hydraulic turbine generator is the three-phase AC excitation type, only be suitable for having abundant water resources, the area that industrial development is concentrated, and the vertical single-phase AC permanent-magnet hydraulic turbine generator that is applicable to the rural households of the few electric single household of mountain area lack of water be nobody shows any interest in, from existing data, also there is not such hydraulic turbine generator.Permanent magnet generator just as the pilot exciter of large turbo-type generator (its frequency be 400 or 500HZ), just causes makers' research of each motor both at home and abroad and attention in recent years.The vast rural area of China solves single household's electrical problem now, what comparatively generally adopt is way with shunt capacitance on the existing squirrel-cage asynchronous motor staor winding, asynchronous motor is used as generator, because the birth defect in the design, the shortcoming of this way is that generating is unstable, need the charging excitation, and water usage is big, is a kind of makeshift.
The utility model will be made a kind of few electricity of mountain area lack of water, vertical single-phase AC permanent-magnet hydraulic turbine generator that rural area single household uses of being suitable for exactly.
The utility model is a kind of by bearing cap; loam cake, lower cover; rolling bearing; thrust-bearing, stator, water wheels casing; coupling rod; incorporated water wheels of flywheel and vane group, and be arranged in the vertical single-phase AC permanent-magnet hydraulic turbine generator that the rotor on the garden cylinder of rotor shaft constitutes by the long strip permanent magnet vertically equably, bearing cap are used for seal protection generator rolling bearing.Loam cake is used for protecting generator unit stator and rotor, and stator is fixed on down and covers, and rolling bearing is fixed on the upper end of the axle of rotor, and thrust-bearing is fixed on the lower end of the axle of rotor, is used for reducing friction and bearing axial load.Coupling rod is used for connecting lower cover and water wheels casing.The water wheels casing is used for covering water wheels, and a current water intake is arranged on it usually.The arc shaped blade of water wheels is welded equably on the garden cylinder around the flywheel, under the impact of current, drives the generator amature rotation.This water wheels structure has been simplified the whole generator structure, has reduced volume, has saved steel.The rotor that is arranged in equably vertically by the long strip permanent magnet on the garden cylinder of rotor shaft produces rotating magnetic field, and induced potential in staor winding makes generator for electricity generation, makees generator amature with permanent magnet, makes rotor magnetic pole need not exciting winding.Show that according to experiment motor number of pole-pairs P of the present utility model is between 5～12.This arrangement mode of the utility model permanent magnet is convenient to fixedly secure so numerous magnetic pole on generator amature, be suitable for the generator high speed rotating, and electric energy loss is little.The generator heating is few, and potential waveform is good, and is reliable, and noise is little.
Current water intake on the water wheels casing of the present utility model can be three, and the garden that is evenly distributed in the water wheels casing is on week, and this evenly distributed a plurality of water intakes make the water of the small water flow water wheels of also getting excited, and make generator starting easy.After on the water intake gate being installed, can open and close water intake easily according to the current size, be convenient to the regulator generator rotating speed, reach the purpose of voltage stabilizing.
Turbine blade of the present utility model can be a hemisphere face shape, and the blade of this shape is convenient to produce in batches with mould, and the spherical blade that makes can be welded on the flywheel of water wheels, makes the making of water wheels simpler.
The utility model is a kind of reasonable in design, the simple vertical single-phase AC permanent-magnet hydraulic turbine generator of small capacity.Motor number of pole-pairs P is chosen between 5～12, and the capacity of can designing is 100～250 watts a alternator.In the mountain area of lack of water, as long as 10 meters high heads are arranged, 5～12 millimeters thick current just can make generator for electricity generation.The water of the small water flow of China's mountain area dispersion can unlikelyly be run off in vain, sent electric energy here for huge numbers of families' hill farmer again, for the hill farmer of single household dispersedly use household electric appliance provide real may, for quickening China's building of the four modernizations and changing the mountain area backwardness, will play immeasurable contribution.
