Description
Technical field
The present invention relates to adopt tracking cell to utilize sun power, relate in particular to and adopt tracking cell to utilize a kind of one dimensional driving bidimensional output device robot mechanism towards solar tracking in sun power.
Background technology
Solar automatic tracking system can increase the sun power that photovoltaic module receives, and improves daily power and year output power, but higher than fixed system cost, and more complicated.There are the problems such as the product systems reliability can not meet the demands, tracking error large, high cost in solar tracking system, how to design a kind of sexual valence high solar tracking system of gain that when generates electricity, both improved generated energy, and reduced again cost of investment and become problem demanding prompt solution.Existing solar tracking system mainly contains one-axis system, Twin-shaft machinery tracing-positioning system, and is specific as follows:
(1) uniaxiality tracking
Uniaxiality tracking generally adopts: the thing that 1. is in tilted layout is followed the tracks of; 2. focal line north and south is horizontally disposed, and thing is followed the tracks of; 3. the focal line thing is horizontally disposed, and follow the tracks of in north and south.The north-south that these three kinds of modes are all single axle rotation or east two are to tracking, and principle of work is substantially similar.The the principle of 1. planting tracking mode is that the rotating shaft north and south of tracking means is arranged, and the geographic latitude angle of the locality that tilts, east-west direction is followed the tracks of the sun, the Spring Equinox, the Autumnal Equinox two days among 1 year, sunray is vertical with cell panel, and all the other time sunray incident angles-23.5 ° and+23.5 ° between; The the principle of 2. planting tracking mode is that the rotating shaft North and South direction of tracker is arranged, according to the variation of the solar hour angle of calculated in advance, solar panel is done around the shaft uniform rotation and followed the tracks of the sun.Adopt this tracking mode, among 1 year, sunray is all oblique fire, and only the cell panel angle of incidence of sunlight is minimum constantly at high noon every day, and this moment, photovoltaic cell output was maximum; The 3. to plant tracking mode be that the rotating shaft thing is horizontally disposed, automatically adjusts cell panel according to the variation of the declination angle of calculated in advance and make around the shaft pitch rotation and follow the tracks of the sun, and the sun is followed the tracks of in the position of perhaps manually adjusting rotating shaft according to variation throughout the year.Theoretical analysis, among 3 kinds of uniaxiality trackings, 1. plant the mode optimum, and 3. to plant mode the poorest.Although single shaft tracking structure is simple, because incident ray can not be parallel with rich optical axis all the time, the effect of collecting sun power is unsatisfactory.
(2) double-axis tracking
Just can obtain maximum sun power if can both follow the tracks of the sun in the variation at altitude of the sun and declination angle, comprehensive trace is that double-axis tracking designs according to such requirement.Double-axis tracking can be divided into dual mode again: polar mounts comprehensive trace and elevation angle orientation angie type comprehensive trace.
The polar mounts comprehensive trace.One axle of its tracking means points to celestial sphere arctic, namely parallels with earth's axis, therefore be called pole axis; Another axle is vertical with pole axis, is called declination axis.During work, cell panel turns round around pole axis, and the setting of its rotating speed is opposite with rotational-angular velocity of the earth size equidirectional to be changed in order to the hour angle of following the tracks of the sun; Cell panel is in order to follow the tracks of the variation at declination angle around declination axis as pitch rotation.This tracking mode is also uncomplicated, but structurally the weight of cell panel is not by the pole axis axis, and the design comparison of pole axis fulcrum arrangement is difficult.
Elevation angle-orientation angie type solar tracking.Elevation angle and orientation angie type sun tracing method are called again horizontal system of coordinates double-axis tracking, and the azimuth axis of cell panel is perpendicular to ground level, and another root axle is vertical with azimuth axis, is called pitch axis.During work, cell panel rotates around azimuth axis according to the change in location of the sun and changes the position angle, does around pitch axis the pitch angle that luffing changes cell panel, thereby makes the normal of cell panel parallel with sunray all the time.The characteristics of this tracker are that tracking accuracy is high, and the weight of heat collector remains in the plane at Z-axis place, and the design comparison of supporting structure is easy.
Existing two axle solar tracking mechanisms have two classes basically, and a class is position angle/pitching angie type, and another kind of is polar mounts.Because the solar tracking mechanism load-bearing of polar mounts is uneven, be unsuitable for using in large-scale tracker.The follower principle of position angle pitching angie type is simple, needs the driving of diaxon, and manufacturing cost is high.There is document to propose spherical mechanism in parallel with three axles as follower, this mechanism structure complexity, and need Three-axis drive, manufacturing cost is higher.
