As shown in figure 18 be that photovoltaic array support of the present utility model can adopt flat uniaxiality tracking and the fixing adjustable mode combining.In other embodiment of the present utility model, also can adopt the axis of girder 11 horizontal by oblique uniaxiality tracking and the fixing adjustable mode combining of certain inclination alpha, as shown in Figure 25, Figure 26, but the inclination alpha of this oblique single shaft is unsuitable excessive, inclination alpha is crossed conference while making uniaxiality tracking and fixing adjustable mutual switching, operating difficulties, is even difficult to realize.This inclination alpha generally should not be greater than 10 °.
In conjunction with Figure 17 to Figure 26, the operation principle of this uniaxiality tracking and the fixing adjustable photovoltaic array support combining as described later simultaneously.
In the time that summer, spring, autumn, sun altitude was higher, photovoltaic array of the present utility model moves in flat uniaxial tracking bracket mode, and girder is arranged in parallel along north-south, as shown in Figure 17, Figure 18.Each girder section east-west direction spacing is definite value L; The girder segment length at the horizontally rotated position of girder is also got L(for ease of disassembling and rotating, and section length also can be slightly less than L); In every pack support, the quantity of girder be two and more than; The number of fragments of every girder be the quantity of girder section be two sections and more than.Photovoltaic module, under the driving of drive unit, is followed the tracks of the azimuthal variation of the sun, slowly rotates from east to west, makes photovoltaic module sensitive surface at East and West direction vertical sunlight all the time, and then improves the daily generation of photovoltaic module.
Arrive winter solar elevation angle step-down, flat uniaxial tracking bracket mode energy output is during lower than best fixed angle support mode, switching to best fixed angle support mode moves, as Figure 19, shown in Figure 20, girder is untied at connecting portion, untie the rotating latch of the rotating supporting member on main supporting member simultaneously, together 90-degree rotation of photovoltaic module by girder section together with top, girder section is arranged along East and West direction, then, again girder section is firmly connected with connector, and lock the rotating latch of main supporting member, simultaneously, according to the photovoltaic module of sun altitude situation adjustment at that time mounted angle, and lock recliner.Girder is along the postpone of East and West direction cloth, long if every row's thing two ends or the wherein girder of one end are encorbelmented, and can set up in this end a supplemental support, as shown in Figure 17, Figure 19.
The advantage of the photovoltaic array support of previous embodiment and other embodiment of the present utility model is as described below.
First, it has overcome flat uniaxiality tracking or the oblique uniaxial tracking bracket mode of small inclination in high latitude area generating electricity in winter amount deadly defect on the low side, and the advantages such as its floor space is little, convenient for installation and maintenance, cost is lower, generating increment is large are given full play to.
Secondly, adopting manual adjustments fixed support mounted angle mode is the most simple and effective method of one that increases energy output winter.A large amount of experimental results show, in the winter time because sun altitude is lower, hours of daylight is shorter, uniaxiality tracking mode is from east to west not remarkable compared with best fixed angle mode to the increase effect of photovoltaic module energy output, the daily generation of photovoltaic module depends primarily on its mounted angle, for this reason, people attempt adopting the oblique uniaxiality tracking mode of high inclination-angle to make up this defect, but what bring is that photovoltaic array floor space expands thereupon, technical requirement uprises, and installation difficulty becomes the problems such as large and the remarkable increase of cost.Taking China be relatively applicable to building large-scale ground photovoltaic plant the Northwest as example: in the time that the girder of oblique single shaft and horizontal plane inclination angle reach 20 °, the floor space of photovoltaic array will increase approximately 1 times than best fixed angle mode, and cost also will increase 30%-50%.And from actual effect, now the daily generation in winter is still low than best fixed angle mode, lowest amplitude still can reach more than 15%.On the other hand, in the time that the girder of oblique single shaft and horizontal plane inclination angle reach more than 25 °, the technical difficulty of its realization increases, and floor space and cost also all can further increase.And excessive mounted angle can produce adverse influence to the energy output increase in photovoltaic module summer.Therefore, adopting the oblique uniaxiality tracking mode of high inclination-angle is not to solve the generating electricity in winter amount best approach on the low side.And adopt uniaxiality tracking and the fixing adjustable photovoltaic array support combining, and both organically can be combined in the technical advantage of different periods, make its annual comprehensive electric generating performance reach best.In recent years, along with declining to a great extent of photovoltaic module and power plant construction cost, the advantage of uniaxiality tracking mode weakens gradually, and people adopt easy single optimum angle of incidence fixed support mode more.And utility model and the appearance of uniaxiality tracking and the fixing adjustable photovoltaic array support combining, will for people provide one more efficiently, more practical, the better photovoltaic array support of cost performance.
In addition, uniaxiality tracking and the fixing adjustable photovoltaic array support combining also have good energy-conserving action.Adopt this photovoltaic array support can make same photovoltaic module can send more electric energy in its identical life cycle, this also just means that whole photovoltaic industry chain will be still less with respect to the specific energy consumption of its final products electric energy.Therefore, its energy-saving effect is also apparent.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, not departing from spirit and scope of the present utility model, can make possible variation and amendment.Therefore, every content that does not depart from technical solutions of the utility model, any amendment, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection range that the utility model claim defines.
