Be provided with an arm of force beam 21 formed as one with girder truss in the middle part of described girder truss, described arm of force beam 21 extends and in the horizontal direction perpendicular to the bearing of trend of girder truss.Described arm of force beam 21 is fixed with balancing weight 22, and described balancing weight 22 is positioned at the opposite side of photovoltaic module plate 6 and mirror board 7, for making the center of gravity of biaxial sun-tracking follower near vertical turning axle, strengthens stability and the resistance to capsizing of the first supporting construction 2.Be fixed with a roller 20 bottom the two ends of arm of force beam 21 respectively, described roller 20 to be fixedly installed under described girder truss and to roll and is installed on round circular orbit 10.
Described first driving mechanism 4 comprises windlass 41 and wire rope 42, windlass 41 is fixed on the arm of force beam 21 of girder truss, the output terminal of windlass 41 is intertwined by wire rope 42 with basis 4 or round circular orbit 10, described windlass 41 drags girder truss by wire rope 42, is rotated on basis 1 by roller 20 along round circular orbit 10.Particularly, in embodiments of the present invention, windlass 41 is fixed on one end of arm of force beam 21, and wire rope 42 is wound around a circle and fixes with it in basic 1 southern side on basis 1, also on the output terminal roll shaft of windlass 41, is wound around a few simultaneously.When windlass 41 rotates, by the dragging effect of wire rope 42, windlass 41 self is rotated around basis 1, drag the first supporting construction 2 axis vertically simultaneously and rotate.
Described second supporting construction 3 is articulated with on the top boom at described girder truss top by least two bearings 30.Described second driving mechanism 5 comprises at least two electric pushrod parts, and the lower stiff end of described electric pushrod parts is articulated with on the web member of girder truss side, and upper movable end and second supporting construction 3 of electric pushrod parts are hinged.
Be fixed on the photovoltaic module plate 6 in the second supporting construction 3 parallel with the bearing of trend of girder truss with the length bearing of trend of mirror board 7.Described photovoltaic module plate 6 is identical with the pattern length of mirror board 7, and the pattern length of photovoltaic module plate 6 is 1.5 to 5 times of the combined width of photovoltaic module plate 6, and namely the pattern length of photovoltaic module plate 6 is much larger than its combined width.This makes the combined area of photovoltaic module plate 6 be flattening, causes array center of gravity lower.It should be noted that, the plate of photovoltaic module described in the embodiment of the present invention 6 can be formed by some sub-photovoltaic module plate permutation and combination, described mirror board 7 can be formed by some sub-mirror board permutation and combination, therefore the pattern length of the photovoltaic module plate 6 described in the present embodiment and combined width refer to entire length and the width of the photovoltaic module plate 6 after combination respectively, the pattern length of mirror board 7 and combined width refer to mirror board 7 entire length after combination and width respectively.
Described second driving mechanism 5 is connected with the controller of windlass 41 with an outside, in the photovoltaic arrays of multiple biaxial sun-tracking follower composition, second driving mechanism 5 of all biaxial sun-tracking followers and windlass 41 can be connected to unified controller, to realize colony's synchro control.During biaxial sun-tracking follower work of the present invention, windlass 41 is under the electric signal instruction that controller sends controls, drag girder truss along vertical axis rotary motion by wire rope 42, thus realize the azimuthal variation of photovoltaic module plate 6, namely according to the azimuthal variation of the sun and real-time change; Electric pushrod parts, under the electric signal instruction that controller sends controls, promote the second supporting construction 3 along horizontal axis rotary motion, thus realize the luffing angle change of photovoltaic module plate 6, namely change and real-time change according to the elevation angle of the sun.Generally speaking, first driving mechanism 4 and the second driving mechanism 5 close fit, drive the first supporting construction 2 and the second supporting construction 3 respectively around vertical axis and horizontal axis rotary motion, make photovoltaic module plate 6 keep vertical relation with the projecting direction of direct sunlight A all the time, keep maximum generation income amount to make photovoltaic module plate 6.
Biaxial sun-tracking follower in hinge structure, the greatest improvement of the embodiment of the present invention is: mirror board 7 has been set up in the bottom of the second supporting construction 3, and within the shade behaviour area of mirror board between each array photovoltaic panel, and mirror board 7 is relative fixing with photovoltaic module plate 6 position, synchronous axial system.Be greater than 90 degree because mirror board 7 and photovoltaic module plate 6 have one and be less than the angle α of 135 degree, and photovoltaic module plate 6 keeps vertical with the projecting direction of direct sunlight A all the time, so the sunshine received can reflex on photovoltaic module plate 6 by mirror board 7, strengthen the light radiation that photovoltaic module plate 6 receives, and then increase generated energy income.
Especially, consider the Cost Problems of mirror board 7, to make the sunlight that mirror board 7 reflects obtain the most sufficient and equally distributed utilization, then need to make the sunlight of mirror board 7 low order end edge incidence in shown in Fig. 1 just reflex to the top edge of photovoltaic module plate 6.Now, the angle α between photovoltaic module plate 7 and mirror board 6, the combined width L of mirror board 2with the combined width L of photovoltaic module plate 1between there is following relation:
L 2=L 1×[sin(180°-α)×cot(α-90°)-cos(180°-α)]
According to above relational expression, as the combined width L of mirror board 2with the combined width L of photovoltaic module plate 1when determining, the best value of the angle α between photovoltaic module plate 7 and mirror board 6 can be calculated very soon.
Based on above-mentioned improvement, the present invention has following beneficial effect:
1, annual generated energy income significantly increases.
In China's To Golmud of Qinghai area, according to statistics display, use the biaxial sun-tracking follower not with mirror board 7 in prior art, comparable fixed angle support mode increases annual generated energy about 35%.
The biaxial sun-tracking follower of the embodiment of the present invention, the direct sunlight A received by mirror board 7 all and reflex on photovoltaic module plate 6 equably, significantly can increase the generated energy of photovoltaic module plate 6.
Suppose the combined width L of mirror board in Fig. 1 2the combined width L of photovoltaic module plate 150%, namely the area of mirror board 7 is 50% of photovoltaic module plate 6 area.Now, mirror board 7 is 126.5 ° with the optimum angle α of photovoltaic module plate 6, is about 29.5% by calculating the light radiation of known increase.Then compared to fixed angle support mode, the annual generated energy that can increase is (1 × 1.35 × 1.295-1) × 100%=75%, and namely increasable annual generated energy is about 75% in theory.Consider the consume in Practical Project, still can increase about 60% of annual generated energy.
Suppose the combined width L of mirror board in Fig. 1 2the combined width L of photovoltaic module plate 1100%, i.e. the area of mirror board 7 and the area equation of photovoltaic module plate 6.Now, mirror board 7 is 120 ° with the optimum angle α of photovoltaic module plate 6, is about 50% by calculating known increase light radiation.Then compared to fixed angle support mode, the annual generated energy that can increase is (1 × 1.35 × 1.50-1) × 100%=102.5%, and namely increasable annual generated energy is about 100% in theory.Consider the consume in Practical Project, still can increase about 80% of annual generated energy.
2, the utilization ratio of land resource improves greatly.
In prior art, in order to the light radiation intensity improving photovoltaic module plate 6 unit area must increase the consumption of land resource.Biaxial sun-tracking follower of the present invention, adds mirror board 7 at the lower eaves of photovoltaic module plate 6, and in photovoltaic array, the distance between adjacent biaxial sun-tracking follower still remains unchanged.Its nature and feature the optical radiation resource be wasted in shade zone of action between former array is carried out excavating and utilizes.Its feature being different from prior art is: the light radiation intensity improving photovoltaic module plate 6 unit area, and does not increase the consumption of land resource.This raising land resources utilization rate, to improve the theory of soil natural endowment development of resources quantum of output, has important social and economic significance, especially for south, the Middle East densely inhabited district that China's land resource is precious.
In To Golmud of Qinghai area, the land use index of existing photo-voltaic power generation station is: identical installed capacity, and traditional solar tracking follower is than the soil of fixed angle support scheme multiplex 75% ~ 80%; Comparatively speaking, when adopting traditional solar tracking follower, although the generated energy of installed capacity improves 30% ~ 40%, the output generated energy in unit area soil greatly reduces 25% ~ 30%.
But adopting the biaxial sun-tracking follower of the embodiment of the present invention, the shade behaviour area due to Appropriate application between adjacent biaxial sun-tracking follower, decreases the waste of land resource; Comparatively speaking, when adopting novel solar tracking follower, the generated energy of installed capacity improves more than 60%, and the quantum of output in unit area soil also improves more than 30%.
3, array resistance to overturning is better.
The biaxial sun-tracking follower of single column of the prior art due to center of gravity higher, single-point support upper load, column root bending moment is very large, need the solid foundation configuring larger-diameter steel column and the larger scale of construction, therefore be difficult to build component palette area more economically more than 100 ㎡, installed capacity is more than single array product of 15KW.And adopting technical scheme provided by the invention, then lower cost can be used to build component palette area more than 100 ㎡, and installed capacity is more than single array product of 15KW.
Because the second supporting construction 3 is that multi-point support is in the first supporting construction 2, and the first supporting construction 2 multi-point support is on round circular orbit 10, round circular orbit 10 is contacted by face or multi-point support is fixed on basis 1, basis 1 be contacted by face or multi-point support on soil base, therefore each level is all multi-point support from top to bottom, and the spacing dimension between each layer strong point is comparatively large, makes array resistance to tipping moment comparatively large, improve resistance to overturning.Again owing to employing girder truss, make the flattening of array component plate combined shaped area, make biaxial sun-tracking follower center of gravity lower, improve resistance to overturning further.Each part of the present invention is simple and practical, and cost relative moderate, makes that the overall manufacturing cost of biaxial sun-tracking follower reduces greatly and technical feature greatly improves.
4, above-mentioned three beneficial effects, impel cost of electricity-generating to reduce further and online sales rate of electricity reduces, and accelerate the development of photovoltaic generation industry.In addition, the embodiment of the present invention had both been applicable to power station, roof and had also been applicable to surface power station.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
