Technical field
The utility model relates to a kind of light-chasing device, is a kind of solar panel automatic spot-following device in particular.
Background technology
Solar energy be on the earth the most directly, the most generally, the most clean, be also the energy that resource is the most unlimited.But the shortcoming that solar energy density is low, dispersiveness large, unsteadiness is large and spatial distribution constantly changes, make the utilance of solar energy lower.The utilization ratio how improving solar energy just becomes the focus of research both at home and abroad.Theory analysis shows, the accurate tracking of the sun is compared with non-tracking, and the acceptance rate of energy differs 38%.Therefore, realizing the accurate tracking of the sun is one of effective way improving solar energy utilization ratio.The mode of current solar tracking mainly contains photoelectric type and mechanical type.Photoelectric type is passive tracking, and its precision is lower, and mechanical type is active tracing, and its principle is that the sun followed the tracks of by control step motor by program computation sunny position.Current most domestic adopts mechanical type to follow the tracks of, but because of without testing agency in this method, cumulative errors is increased gradually, and effect is not very good.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of solar panel automatic spot-following device, can improve tracking accuracy, thus improves the operating efficiency of solar panel.
For solving the problems of the technologies described above, a kind of solar panel automatic spot-following device of the utility model, comprises ARM920T controller, solar panel, PSD detector, motor driver, motor, Twin-shaft machinery support and liquid crystal touch screen.Detect sunray by PSD detector and be irradiated to the electric current that solar panel produces, the ADC given by electric current in ARM920T controller carries out analog-to-digital conversion, is judged the position of the sun by ARM920T controller.Then controlled quentity controlled variable is sent to motor driver with the rotation of the driving motor control Twin-shaft machinery support, reach the attitude of adjustment solar panel, i.e. adjustment direction angle and the angle of pitch, thus make solar panel vertical with sunray, make solar panel receive solar energy to greatest extent.In order to increase human-computer interaction function, collection and control result are shown by liquid crystal touch screen by ARM920T controller.
In order to improve tracking accuracy, this solar panel automatic spot-following device adopts double-axis tracking method, and namely solar panel changes deflection and the angle of pitch by vertical axes and trunnion axis self contained function.The mechanical part of this solar panel automatic spot-following device is made up of PSD transducer, solar panel, motor I, T-shaped support, motor II, turbine, universal coupling I, connecting rod, universal coupling II, cam, deceleration box and worm screw.PSD transducer is fixed on the middle part of solar panel, is irradiated to for detecting sunray the electric current that solar panel produces.The lower end of solar panel is movably connected in T-shaped cantilever tip, and the upper end of solar panel is movably connected on cam by universal coupling I, connecting rod and universal coupling II.Cam is fixedly connected on motor I, and motor I is fixed on T-shaped support.Be with moving cam to make solar panel around horizontal axis by motor I, just can realize the adjustment to the angle of pitch.Motor II is connected on deceleration box, by motor II through the T-shaped support of deceleration box deceleration rear drive, just can realize horizontal direction and rotate, be i.e. azimuthal adjustment.Deceleration box is made up of turbine and worm screw, and speed reducing ratio is 40%.By the control to motor I and motor II, just can reach control solar panel being carried out to the angle of pitch and deflection, thus make solar panel vertical with sunray, improve the operating efficiency of solar panel.
