Description

Low latitudes single monocrystal solar cell spotlight tracking device

The utility model relates to a kind of low latitude monocrystalline solar cell condensing tracking device.

At present in order to make full use of solar energy, to day the tracking means kind more, but obviously have following deficiency: (1) some motionless automatic control; (2) certain structures is complicated; (3) cost is higher; (4) following the tracks of the region is restricted.

It is a kind of reliable that the purpose of the low latitude monocrystalline solar cell condensing tracking device of the utility model provides with regard to being to overcome weak point of the prior art, with low cost to the day tracking means, is particularly suitable for the torrid zone, the subtropical zone is used.

The purpose of this utility model reaches by following measure: it is gone out ［ 12 ］ four most of compositions of fixed support of formula gearbox ［ 5 ］, low latitudes by open low-concentration season axle track frame ［ 1 ］, secondary condensation and heat dissipation type solar module ［ 2 ］, two first day of the lunar year shaft extensions; Its open secondary condensation system forms by being installed in the two plane toughened glass lens ［ 4 ］ on the track frame ［ 1 ］ and cooperating with solar module speculum ［ 3 ］ at an angle; Solar cell in assembly ［ 2 ］ adopts the low-resistivity monocrystalline silicon between the 0.3--3 Ω .cm, and between 1.8--2.5mm, heating panel is installed at the assembly back side to grid line at interval; Sleeve pipe ［ 6 ］ and day axle ［ 8 ］ are stretched out in gearbox ［ 5 ］ two ends, and season axle ［ 7 ］ is vertical mutually with day axle ［ 8 ］, and two cover optically focused season axle track frames ［ 1 ］ of symmetry are installed respectively on day axle ［ 8 ］; Fixed support ［ 12 ］ is herringbone by having arc groove ［ 9 ］ and becoming 65 ° with horizontal plane--and the directed hound ［ 11 ］ and the fastening bolt ［ 14 ］ at 85 ° of angles are constituted with latitude axle bolt ［ 10 ］ and four anchor bolts ［ 13 ］.

Be welded with two screw rods on the gearbox ［ 5 ］, wherein Shang Mian a screw rod can slide in arc groove ［ 9 ］, back to be positioned is fixing with fastening bolt ［ 14 ］, and another root screw rod (being positioned at the circle centre position of arc groove ［ 9 ］) is made latitude axle usefulness, and it is fixing with bolt ［ 10 ］ to pass hound ［ 11 ］.

The drawing explanation of accompanying drawing:

Figure one: condensing tracking device overall structure figure;

Figure two: optically focused season axle track frame stereogram.

The utility model will be further described below in conjunction with drawings and Examples:

The utility model adopts a kind of sunlight that makes through direct projection, scattering, refraction and reflect the secondary condensation system of four part combinations, its secondary condensation system goes up the plane toughened glass lens ［ 4 ］ of installation by spotlight tracking frame ［ 1 ］ and forms with solar module ［ 2 ］ speculum ［ 3 ］ at an angle, at the solar module back side heating panel is housed, makes solar module have good ventilation and heat performance; And adopt the monocrystalline solar module that can be preferably adapts with low-concentration, the matrix resistivity of monocrystalline is lower, between 0.3--3 Ω .cm, the series resistance of solar module is reduced as far as possible, make it under low-concentration, still keep fill factor, curve factor preferably, the annual opto-electronic conversion ability that reaches the monocrystalline solar module improves more than three times.

The utility model stretches out a day axle ［ 8 ］ from gearbox ［ 5 ］ two ends symmetry and links with spotlight tracking frame ［ 1 ］, season axle ［ 7 ］ is vertical mutually with day axle ［ 8 ］, the regular vernier knob of season axle ［ 7 ］ also is installed on the spotlight tracking frame ［ 1 ］ at two ends, finely tuned in 3-10 days, and can reach the annual required precision of the sun of following the tracks of.Screw rod and fastening bolt ［ 14 ］ that fixed mount ［ 12 ］ can slide in arc groove ［ 9 ］ by latitude axle and latitude axle bolt ［ 10 ］ and when loosening, can make gearbox ［ 5 ］ all rotate to 30 ° with interior arbitrary position from horizontal level shown in Figure 1 around the latitude axle together with the spotlight tracking frame at two ends, inclination angle up to day axle ［ 8 ］ is identical with local latitude, just fastening bolt ［ 14 ］ is tightened, adjust the orientation of fixed support ［ 12 ］ again, the perpendicular that makes hound ［ 11 ］ be positioned at positive north and south is fixed fot screw and can be realized day is followed the tracks of.

The utility model has following advantage compared to existing technology: it can make the annual photoelectric conversion capacity of monocrystalline solar cell improve more than three times, combine with any existing one dimension autotracker and just can realize annual accurate tracking to the sun, simple in structure, reliable and with low cost, the tropical and subtropical region that is best suited between 30 ° of 30 °-north latitude of south latitude uses.
