Traditional solar photovoltaic assembly mostly adopts fixed installation, and promptly cell panel is fixed on the supporting structure, does not move with the variation of position of sun, and such result is with having a strong impact on conversion efficiency.This is because the generated energy of solar photovoltaic assembly array is relevant with sunlight angle of incidence of light degree, and the light solar radiation quantity that photovoltaic array receives during perpendicular to the assembly plane is maximum, its generated energy maximum.For the photovoltaic module of high power concentrator, only under the prerequisite of sun direct projection, could realize high conversion.In order to address this problem, solar automatic tracking system arises at the historic moment.Adopt solar automatic tracking system can guarantee the vertical all the time of photovoltaic module and sunshine light to the full extent.
Use automatic tracking system widely now; Comprise two kinds of uniaxiality tracking and double-axis trackings; Wherein the double-axis tracking photovoltaic array moves along two turning axles; Can follow the tracks of the position angle of the sun and the variation of elevation angle simultaneously, the running orbit that can follow the tracks of the sun in theory fully is to realize the vertical incidence angle of light.At present, the double-shaft solar tracking means is the most general with column, the most cantilever designs that adopt of its elevation angle driving shaft, and driving shaft is the torsion tube formula.Indeformable in order to guarantee driving shaft, the common diameter of axle, wall thickness are selected for use all bigger, cause from great, and material and self power consumption are bigger, less economical.
The utility model content
The technical matters that the utility model will solve is that structure is light, cost is low, wasted work is few, the solar biaxial tracking means of good economy performance.
In order to solve the problems of the technologies described above, the utility model provides a kind of solar biaxial tracking means, comprises column; Said column upper end is provided with the position angle drive unit; Drive unit top, said position angle is provided with supporting part, and said supporting part top is provided with the elevation angle drive unit, and said elevation angle drive unit both sides are respectively equipped with the erecting frame that is used to install photovoltaic module; The middle part of erecting frame is provided with horizontal rotating shaft, and an end of said rotating shaft is connected to said elevation angle drive unit.
The solar biaxial tracking means of the utility model also comprises the U-shaped frame, and said U-shaped frame top is connected to the side of said supporting part, and the bottom contacts with the track that is located on said column bottom through supporting castor; The two ends of said rotating shaft are passed through Bearing Installation respectively to said U-shaped frame.
Said U-shaped frame is processed by hollow tubular.
Said U-shaped frame is processed by the truss-like casing.
The height of the truss-like casing of the horizontally set that is positioned at the bottom of said U-shaped frame is greater than the width of the truss-like casing of the vertical setting that is positioned at both sides.
Each said U-shaped frame bottom is provided with two support castors.
Said supporting part is a load-bearing casing.
The utility model has been realized the adjustment of position angle and elevation angle through setting two pole axis, and the structure stress of bipolar axle is reasonable, not yielding, and therefore the requirement to structural strength can reduce, thereby can reduce the use of material, saves production cost; Owing to reduced material, its weight also can alleviate, and can reduce operating power consumption, has reduced operating cost, has improved economy greatly simultaneously.

Fig. 2 is the partial top view of the solar biaxial tracking means of the utility model.
Fig. 3 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: 1. erecting frame, 2. bearing, 3.U shape frame 4. supports castor, 5. track, 6. column, 7. position angle drive unit, 8. supporting part, 9. elevation angle drive unit, 10. rotating shaft.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further so that those skilled in the art can better understand the utility model and implementing, but the embodiment that lifts not conduct to the qualification of the utility model.
Embodiment as depicted in figs. 1 and 2, the solar biaxial tracking means of the utility model comprises column 6; Column 6 upper ends are provided with position angle drive unit 7; Drive unit 7 tops in position angle are provided with supporting part 8, and supporting part 8 tops are provided with elevation angle drive unit 9, and elevation angle drive unit 9 both sides are respectively equipped with the erecting frame 1 that is used to install photovoltaic module; The middle part of erecting frame 1 is provided with horizontal rotating shaft 10, and an end of rotating shaft 10 is connected to elevation angle drive unit 9.In the use, photovoltaic module is installed on the erecting frame 1, and elevation angle drive unit 9 rotates through rotating shaft 10 drive installation framves 1, thus the elevation angle of adjustment photovoltaic module.The supporting part 8 that position angle drive unit 7 drives its top rotates along Z-axis with elevation angle drive unit 9, thereby can adjust the position angle of photovoltaic module.
Preferably; The utility model can also comprise U-shaped frame 3; The two ends of rotating shaft 10 are installed on the U-shaped frame 3 through bearing 2 respectively, and U-shaped frame 3 tops are connected to the side of supporting part 8, and the bottom contacts (referring to Fig. 3) through supporting castor 4 with the track 5 that is located on column 6 bottoms.U-shaped frame 3 obtains anchorage force through supporting castor 4 with contacting of track 5, offsets the downforce that outboard bearing bore, and can guarantee the right alignment of U-shaped frame 3 bearings at both ends, reduces the eccentric energy loss of bringing.Each U-shaped frame 3 preferably supports (being equivalent to a V-type groove) by 2 support castors 4, is easy to support the adjusting coaxial with column of castor 4 orbits, and 2 support castors 4 evenly are pressed on the track, guarantees 3 even runnings of U-shaped frame.
