Abstract
The invention discloses a polar shaft type photovoltaic power generation apparatus. The apparatus comprises a base, a polar shaft and an arc tooth bar. The base is composed of a cross beam and a longitudinal beam. A pillar is fixed on the longitudinal beam. A shaft sleeve is hinged to the top of the pillar and is in rotatable connection with the polar shaft. Linkages are fixed at the two ends of the polar shaft. A first reduction motor is mounted at the bottom of the shaft sleeve. A pinion is mounted on an output shaft of the first reduction motor. A bull gear is mounted on the polar shaft. The pinion and the bull gear are engaged. A photovoltaic assembly is arranged above the shaft sleeve. The bottom of a frame is fixedly connected with the top portions of the linkages. A bend beam is mounted on the linkage at the left end of the polar shaft. A light tracer is mounted at the top of the bend beam. One end of the arc tooth bar is fixedly connected with the left end of the shaft sleeve while the other end of the arc tooth bar passes through the lower part of the pillar and is in sliding connection with the pillar. A support bar is fixed on the cross beam. A second reduction motor is mounted at the top of the support bar. A worm is connected with the end part of an output shaft of the reduction motor, and the helical teeth of the worm mesh with the teeth on the arc tooth bar. The tracking mechanism of the polar shaft type photovoltaic power generation apparatus itself is quite energy-saving.
Description
Technical field
The invention belongs to photovoltaic power generation technology field, specifically relate to a kind of polar mounts photovoltaic generation dressPut.
Background technology
In fact geographic latitude is equivalent to the line in certain any same the earth's core (center of circle) on the earth, with equatorBetween angle; Sun altitude, is in fact equivalent to sunray and (supposes that sunray is parallelLight) with the angle between excessively local disc tangent line (horizon); Direct sunlight line is perpendicular toEarth surface (disc), the inevitable vertically horizontal line of direct projection light, and sun direct projection soThe extended line of light must be crossed the earth's core. Conventionally we represent somewhere height of the sun at noon with h, itOn numerical value, equal the altitude of the sun in the coordinate system of celestial horizon. Sun altitude along with local timeWith the variation of the declination of the sun and change. Solar declination represents with δ, observes ground geographic latitude show with φShow, local time (hour angle) represent there is the computing formula of sun altitude with t: sinh=sin φSin δ+sin φ cos δ cost. Day rises sunset, and in same place one day, sun altitude is continuousChange. When sunrise sunset, angle is all zero degree, positive period of the day from 11 a.m. to 1 p.m sun altitude maximum. Because the positive period of the day from 11 a.m. to 1 p.mThe local time t=0 waiting, so the sun altitude when high noon can be with following formula calculating: forThe Northern Hemisphere, H=90 °-(φ-δ); For the Southern Hemisphere, H=90 °-(δ-φ).Summer solstice, the sun direct projection tropic of cancer, north latitude 23.5 is spent; The winter solstice sun direct projection tropic of Capricorn,Be that south latitude 23.5 is spent. Centre 47 latitudes of being separated by, be 365.26/2=182.63 days half a year. From the summerTo Winter Solstice, subsolar point moves southwards from north latitude 23.5 degree, moves 47/182.63=0.2574 every dayIndividual latitude, is to move on to south latitude 23.5 winter solstice to spend after half a year, then northwards puts again, equally with every dayThe speed of 0.2574 latitude, through 182.63 days, the summer solstice got back to north latitude 23.5 and spends. By thisCan very accurately find the latitude of subsolar point every day, i.e. solar declination δ.
In this case, when adopting solar declination and pole axis, we follow the tracks of track of sun, significantly,The excursion of solar declination is very little, and namely the motion frequency of this direction and motion amplitude are less, because ofThis is very energy-conservation; But existing tracking mode often only adopts uniterminal axis or traditional twin shaft to followTrack, it does not possess power saving function.
