Embodiment
As shown in Figure 1, it comprises photo-voltaic power supply automatic tracking controller 4, main shaft 3, position angle detecting device 5, DC electromagnet 6, ratchet and pawl arrangement 7, pattern guide rail 2, and position angle detecting device 5 is arranged on main shaft 3; As shown in Figure 4, ratchet 18 is arranged on main shaft 3, and fixes with main shaft 3, can rotate with main shaft 3; Ratchet 19 is arranged on a rocking arm 20, is kept being adjacent to ratchet 18, and be connected with DC electromagnet 6 through electromagnet push-rod 21 by extension spring 22; Photo-voltaic power supply automatic tracking controller 4 is arranged in the main shaft cover 8 outside main shaft 3; As shown in accompanying drawing 2,3, pattern guide rail 2 is annular, be enclosed within main shaft 3 top, one end is hinged on pattern guide rails assembling plate 17, the hinged adjustment screw mandrel 12 of the other end, regulate screw mandrel 12 through pattern guide rails assembling plate 17, on the above and below adjustment screw mandrel 12 of pattern guide rails assembling plate 17, each installation setting nut 13,16 and spheric washer 14,15; When needs reduce elevation angle, first inhour setting nut 13 above can be rotated, and then the setting nut 16 below that turns clockwise; In like manner, when needs increase elevation angle, first inhour can rotate setting nut 16 below, and then the upper setting nut 13 in the face that turns clockwise; Pattern guide rails assembling plate 17 is horizontally fixed on main shaft cover 8 upper end; Main shaft 3 is hinged on below solar cell array plate 1 through pattern guide rails assembling plate 17 top, a transfer roller 10 is had to be arranged on below solar cell array plate 1 through a transfer roller support 11, be close to pattern guide rail 2, when main shaft 3 drives solar cell array plate 1 to rotate, transfer roller 10 is close to pattern guide rail 2 and is rolled.
Principle of work of the present utility model is: mode that photo-voltaic power supply automatic tracking controller 4 adopts " closed loop time control tracking ", with reference to the principle of celestial navigation, according to the earth along equatorial plane rotation and the rule around the revolution of sun ecliptic plane, the sun sometime relatively the real time position of certain coordinate points of the earth be relatively-stationary, namely solar cell array plate 1 is also relatively-stationary relative to sun position angle sometime and elevation angle.The utility model uses high performance STM8(or STM32) position angle in each moment of solar cell array plate 1 and the mathematical model of elevation angle be solidificated in the program of single-chip microcomputer inside with the form of database by one-chip computer, simultaneously, by being arranged on the position angle detecting device 5 on main shaft 3, the bearing data that real-time detection solar cell array plate 1 is current, then by STM single-chip microcomputer, the theoretical position angle in current time database and the true bearing angle detected are compared, and send instruction according to its error timing, electromagnet push-rod 21 is driven to drive ratchet 19 action by DC electromagnet 6, promoting ratchet 18 drives main shaft 3 to turn an angle, while main shaft 3 rotates, solar cell array plate 1 is driven to rotate, when solar cell array plate 1 rotates, transfer roller 10 below it is close to pattern guide rail 2 and is rotated.Accurately follow the tracks of the sun due to solar cell array plate 1 to run, thus substantially increase the control reliability of tracking, the tracking out-of-control phenomenon caused by the factor such as weather effect or cloud cover can not be occurred again.
After position angle detecting device 5 detects that the sun sets, single-chip microcomputer sends instruction, electromagnet push-rod 21 is driven to drive ratchet 19 continuous action fast by DC electromagnet 6, promoting ratchet 18 drives main shaft 3 to rotate half cycle, solar cell array plate 1 is made to arrive initial position, the i.e. position of sun initial rise, prepares the work of next circulation.
In horizontal system of coordinates double-axis tracking process, higher to the Bearings tracking accuracy requirement of east-west direction, so adopt electromagnet 6 driving pawl detent mechanism 7 to follow the tracks of, and the elevation angle change of North and South direction is smaller, regulate screw mandrel 12 to regulate the north and south elevation angle of solar cell array plate 1 by adjustment, rotating adjusting nut 13,16 can make adjustment screw mandrel 12 drive pattern guide rail 2 and solar cell array plate 1 to rise or decline certain angle.Quarterly manual adjustments elevation angle, the angle of annual adjustment is roughly about 10 degree, ensures the tracer request of the elevation angle that still can meet North and South direction while reducing costs.
