Description
Technical field:
The present invention relates to a kind of device of solar generating, belong to application of solar.
Background technology:
Countries in the world are all in active research exploitation renewable energy technologies, solar energy is because of the inexhaustible favor that particularly is subjected to the various countries researcher, but in short supply and cost an arm and a leg and make cost of electricity-generating high because of the highly purified silicon materials that are used for solar energy power generating, so restricting applying of solar energy industry.A lot of for this reason scientific workers are at research optically focused and tracking means, to reach the utilance that improves photovoltaic cell and the receiving efficiency of solar energy.
The beam condensing unit of current research mainly is divided into level crossing optically focused, curved mirror optically focused and convex lens optically focused three major types, optically focused compares from several times to hundred times, but the optically focused more than 2 to 3 times is than making photovoltaic cell must change traditional packaging technology because of temperature is high, have to dispel the heat at the back side of photovoltaic cell with sheet metal or heat radiation, optically focused is than higher photovoltaic power generation apparatus, the back side of photovoltaic cell also must increase recirculated water and cool off, make concentrating generation device make production technology and complex structure because of solving heat dissipation problem, thereby make that the cost increase is bigger, the optically focused mode of some non-planar mirror makes that because of optically focused is inhomogeneous the generating efficiency of photovoltaic cell can not be improved fully, reduces the useful life of photovoltaic cell on the contrary because of the focus of part.
Summary of the invention:
The object of the invention is by low-concentration and double-shaft auto-tracking the energy output of photovoltaic module to be increased, thereby reduces the cost of solar energy power generating.
In order to realize above purpose, the ∧ type speculum optically focused of ∧ type optically focused double-axis tracking solar energy photovoltaic generator is than only designing between 1.3 times-2 times, be to adopt two plate plane speculums to be the ∧ type to install, because of optically focused than little, the temperature that photovoltaic cell increased is very low, in the scope that photovoltaic cell and conventional encapsulant EVA etc. bears, do not need to adopt metal or fin substrate and heat sink material as the photovoltaic cell encapsulation, the photovoltaic module that only needs industrialization, so its cost is lower, and good reliability.
The double-axis tracking device that is provided with, place near the center of gravity of optically focused and power generation part, the also bosom position under ∧ type speculum just in time, make that the tracking energy consumption is very low, this tool face azimuth trail angle maximum can reach 170 °, and through present inventor's Theoretical Calculation, only the energy output that increases because of tracking is about 39%, if add ∧ type optically focused, the sample calculation that increases energy output is as follows:
For example, the drift angle of design ∧ type speculum is 60 degree, the optically focused ratio is 1.5 times, then this Blast Furnace Top Gas Recovery Turbine Unit (TRT) increases (1+0.39) * 1.5=2.085 times approximately because of the energy output of optically focused and the hard-wired photovoltaic module of tracking ratio use equal area, button goes the influence of direct reflection efficient and follows the tracks of energy consumption, energy output still increases about 2 times than dull and stereotyped fixed photovoltaic module energy output, simultaneously reliable, simple in structure because of its technology, be easy to cleaning and heat radiation, all even low cost and other advantages of optically focused, have higher utility, be easy to apply.
In order to realize above purpose, technical scheme of the present invention is: optically focused partly adopts two flat glass mirrors or metallic mirror to be the ∧ type and installs, and two photovoltaic modulies are installed in the bottom in the outside, ∧ type speculum two inclined-planes respectively.For the solar energy that is radiated on the speculum is covered on whole photovoltaic modulies, make the solar energy of photovoltaic module acceptance stack even, so be provided with the double-axis tracking device.It has two following embodiments:
Description of drawings
Fig. 1 is the embodiment of the invention one
Fig. 2 is the embodiment of the invention two
Embodiment one:
As shown in Figure 1, the ∧ type optically focused double-axis tracking solar energy photovoltaic generator of present embodiment, comprise and be two condenser mirrors 1 that the ∧ type is installed, two photovoltaic modulies 2 are installed in the bottom in the outside, 1 liang of inclined-plane of ∧ type speculum respectively, it is parallel with east-west direction that ∧ type speculum is installed on ∧ type bus, export direction rotating shaft 6 and elevation rotating shaft 9 vertical or that intersect on the casing 11 of tracking means, direction rotating shaft 6 is installed on North and South direction.
The tracking of azimuth direction is to be rotated by the azimuth-drive motor 7 on the control circuit control casing 11 of clock rate, the rotation of motor 7 drives the rotation of direction rotating shaft 6 by casing inner orientation deceleration transmission chain, direction rotating shaft 6 two ends are fastened on the hand adjustment latch segment 5, hand adjustment latch segment 5 is fixed on the photovoltaic module support 3, therefore the rotation of direction rotating shaft 6 also drives photovoltaic module support 3, condenser mirror 1, photovoltaic module 2 and does azimuth rotation together, realizes that the azimuth follows the tracks of and return night daytime.Aim at the solar time apace at azimuth direction when first installation or because of other reason need make photovoltaic module 2, can unclamp the lock screw 4 on the hand adjustment latch segment, carry out manual fast tuning.
The tracking of elevation direction is to be rotated by the elevation angle motor on the maximum power point control circuit control cabinet body 11 of gathering photovoltaic module 12, the rotation of motor 12 drives the rotation of elevation angle deceleration transmission chain in the casing, because of elevation rotating shaft 9 is fixed on the supporting fork 10, supporting fork 10 is fastened on again on the column 13, so force the parts of casing 11 and deceleration transmission chain to rotate around elevation rotating shaft 9, photovoltaic module support 3, condenser mirror 1, photovoltaic module 2 are also done the rotation of elevation direction together at this moment, realize elevation angle tracking.Aim at the solar time apace at elevation direction when first installation or because of other reason need make photovoltaic module 2, can unclamp the lock screw 8 that supporting is stuck, carry out manual fast tuning.
Moving because of the orientation of the sun is uniform motion, thereby adopts returning automatically of tracking on daytime of time speed control azimuth motor and night, designs the spacing shutdown switch that tracking end in afternoon is arranged and turn back to initial tracing positional in morning night on direction rotating shaft.Because it is less that change elevation angle every day of the sun, and its variation is non-linear, so the tracking mode of gathering maximum power point is adopted in the tracking of elevation direction, and 12 runnings of may command elevation angle motor.
Embodiment two:
As shown in Figure 2, the basic principle of present embodiment is identical with embodiment one with structure, and unique different place is that the ∧ type that the is installed on bus of ∧ type speculum is parallel with North and South direction.The shortcoming of this embodiment comparing embodiment one is, for long place of some hours of daylight, just there have been the sun or afternoon to follow the tracks of when also not beginning to follow the tracks of in the morning the solar time has still been arranged when stopping, ∧ type speculum has just blocked the sunray of a sidelight photovoltaic assembly, influence the generating of assembly, and embodiment there is not this phenomenon first.
