Description
Technical field
The utility model relates to a kind of solar energy equipment, especially relates to a kind of solar energy tracking device.
Background technology
Existing photovoltaic illuminator generally adopts the collocation of fixing solar panels-energy-storage travelling wave tube, since the position of the sun on high in time with seasonal variations, the efficient of generating depends on the amount of raying, if sunlight is P to the incident angle of solar panels, then specification is that the raying area in the daylight is actual at this moment is cosPA for the solar panels of A (m) * A (m)
2(m
2), efficiency value is cosP.Common solar panels layout is a Due South, and sunlight incidence angle sooner or later changes for the 0-180 degree, and efficiency value also directly changes at 0-1 so, obviously has only the solar energy that utilizes of the meridian hour ability more efficient, and the radiant energy major part of all the other periods has been wasted.
According to being the calculating of vertical incidence angle 1 of high noon, the radiation cross-section that this moment, solar panels obtained is long-pending maximum, it is the energy output maximum, the solar panels utilization ratio reaches the highest, and front and back difference 2 hours 11 and 3 o'clock, the efficiency value of the solar panels that solar incident angle causes in radiation path is cos30 °=0.866, be offset 2 hours and 5 points again at 9, efficiency value has only cos60 °=0.5, as shown in Figure 1, is positive south orientation solar panels raying intensity.Also the average of positive as can be known south orientation solar panels raying intensity has only about 0.5 from figure.
There are many solar tracking apparatus to occur now on the market, most of angle identifier at sunshine of complexity that adopts is determined the angle at sunshine, and then do day and rotate, though played the effect of solar tracking, but during the Practical Calculation input-output, expensive and angle identifier at sunshine that grasped patent has abroad occupied very big cost, makes the losing more than gain of generating quantitative change of amplification.And be not suitable for the application of small-sized off-grid type independent solar system, only could really play practical advantageous effects in large-scale solar power plant.
The utility model content
For overcoming deficiency of the prior art, the purpose of this utility model is to provide a kind of solar energy tracking device, this device is used for the Angular Trackong at sunshine of solar power system, guarantee solar panels and sunshine angle angle remain the right angle, it is long-pending to make solar panels obtain maximum radiation cross-section at sunshine, thereby the times all in whole day can obtain maximum energy, improve whole generating efficiency.
In order to solve the problems of the technologies described above, realize above-mentioned technique effect, the utility model has adopted following technical scheme:
A kind of solar energy tracking device, comprise lamp stand link and solar panels, described solar panels are fixed on the solar energy seat board, described solar energy seat board is fixed on the intermediate support, described intermediate support both sides are fixed with right support and left socle respectively, also be fixed with a countershaft bearing and a main bearing seat on the described lamp stand link, all be provided with bearing in described countershaft bearing and the main bearing seat, one transmission device is installed on the described bearing, described transmission device comprises a motor, described motor is connected with machine shaft, described transmission device is by inserting the two ends of described machine shaft respectively in the described bearing, thereby on the fixing described bearing, be separately installed with pipe spreader on described machine shaft two arms, described pipe spreader and described right support and left socle are fixed.
Preferably, on the bearing of an end of described machine shaft a bearing cap is installed, machine shaft is covered.
Preferably, the other end of described machine shaft is fixed on the bearing by a locking nut.
Preferably, be provided with an axle sleeve between described locking nut and the bearing.
Preferably, described axle sleeve is outside equipped with an accessory cover.
Preferably, be provided with a bearing circlip between described accessory cover and the described bearing.
By analyzing the generating curve of regular solar plate, be the peak value that its daylight utilizes 3 hours high noons, that is in incidence angle positive and negative deviation 15 degree, efficient COS15 °=more than 96.5%, improve the error precision of incidence angle again, at most also can only bring up to 100%, just extra 3.5% efficient, be unnecessary like this, so, if allowed every 3 hours its by tumbler proofread and correct once towards, maintenance is not more than 15% to the incidence angle of daylight, can keep 96.5% efficient power generation state so from sun to sun, can each altitude of the sun tables of data constantly of very simple setting by inquiring about local longitude and latitude, so only need solar panels to be turned to fixing angle, can raise the efficiency greatly in the fixing moment; Rising such as morning and evening sun east that the west falls is 180 to spend the cycle, along with dimension raises the earliest and several hrs the latest be can't see the sun in fact, it is fixing that but the incident angle of the sun remains, so according to calculating good angle, sunrise sunset N hour, the incident angle deviation is calculated less than 15, only need every day Rotate 180/15x2=6 time to satisfy, long in conjunction with local daytime so again when season, can set the concrete cycle of rotation, such as daytime long 9 hours, be exactly that rotation in 1.5 hours 30 degree get final product so, to night rev 180 spend and get back to initial point.
Do not increasing the solar panels area like this, do not using under the situation of expensive day angle of light tracker, relying on simple and collocation reasonably is set and just can improve day energy output of solar panels more than 1 times.
