Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The present invention includes be installed on the electric pole 3 and can around its central axis carry out 180 ° of rotations main shaft 2, be fixedly mounted on main shaft 2 left parts or the right part and the solar energy photovoltaic panel 1 that rotates synchronously with main shaft 2, the driving mechanism 4 that main shaft 2 is driven and driving mechanism 4 is carried out the controller of corresponding control to realize that control main shaft 2 carries out intermittent rotation according to the altitude of the sun angular data of each period that calculates in advance; Said main shaft 2 is in transmission connection with driving mechanism 4 and driving mechanism 4 is electrically connected with controller, and said main shaft 2, driving mechanism 4 and controller are formed the horizontal adjusting mechanism that adjustment is controlled at the position angle of in 2 spinning movements of control main shaft, tackling solar energy photovoltaic panel 1 mutually.Said driving mechanism 4 comprises pulse producer, is carried out the solenoid valve 8 of drive controlling, can drive tooth bar 5 that main shaft 2 rotates synchronously when can pump and pump and carried out 360 ° of rotations and rotation drives the disk 7 that tooth bar 5 pumps simultaneously by solenoid valve 8 controls by pulse that pulse producer produces; Said pulse producer and solenoid valve 8 join; Disk 7 be installed on the solenoid valve 8 and disk 7 and tooth bar 5 between be in transmission connection through gear train; Be in transmission connection between said tooth bar 5 and the main shaft 2, said pulse producer is controlled by controller and itself and controller join.
In the present embodiment; Left part top and the main shaft 2 that said solar energy photovoltaic panel 1 is installed in main shaft 2 plug-in mounting from left to right gone into electric pole 3 inside; The corresponding plug-in opening that supplies main shaft 2 to install that is provided with on the said electric pole 3; Said tooth bar 5 is vertically to laying and it is laid in electric pole 3 right sides, and relative and right part main shaft 2 of the installation position of the installation position of tooth bar 5 and main shaft 2 directly contacts with tooth bar 5.
The actual laying when installing, said disk 7 is laid in tooth bar 5 belows.Said gear train is a connecting rod 6, and the both ends up and down of said connecting rod 6 are installed in respectively on tooth bar 5 and the disk 7, and all is connected through bearing between the both ends up and down of connecting rod 6 and tooth bar 5 and the disk 7.
Because in fact sun altitude is equivalent to sunray (supposing that sunray is a directional light) through the angle between the local disc tangent line (being the local horizon); The direct sunlight line is perpendicular to earth surface, the inevitable horizontal line vertically of direct projection light so, and the extended line of direct sunlight line must be crossed the earth's core.Usually represent sun altitude with h, it is numerically equal to the altitude of the sun in the coordinate system of celestial horizon.Sun altitude along with LZT and the variation of the declination of the sun and changing.Solar declination representes with δ, and observation ground geographic latitude representes with φ, LZT (hour angle) represent that with t the computing formula of sun altitude is arranged: sinh=sin φ sin δ+sin φ cos δ cost.Day rises sunset, and sun altitude is constantly to change in the same place one day.Angle all is a zero degree during sunrise sunset, and just the period of the day from 11 a.m. to 1 p.m, sun altitude was maximum.Because the LZT t=0 in the time of high noon, so the sun altitude high noon the time can calculate with formula: for the Northern Hemisphere, h=90 °-(φ-δ); For the Southern Hemisphere and the side, h=90 °-(δ-φ).Summer solstice, the sun direct projection tropic of Cancer, i.e. north latitude 23.5 degree; The winter solstice sun direct projection tropic of Capricorn, i.e. south latitude 23.5 degree.Centre 47 latitudes of being separated by, be 365.26/2=182.63 days half a year.From Winter Solstice in the Summer Solstice; Subsolar point moves from north latitude 23.5 degree southwards, moves 47/182.63=0.2574 latitude every day, after half a year is to move on to south latitude 23.5 degree the winter solstice; Northwards put again then; With the speed of 0.2574 latitude every day, through 182.63 days, promptly the summer solstice was got back to north latitude 23.5 degree equally.Thereby in advance when each period, the altitude of the sun angular data was calculated, can very accurately find the latitude of subsolar point every day, i.e. solar declination δ according to the aforementioned calculation method.
The course of work of the present invention is: according to the altitude of the sun angular data of each period of realizing calculating; Through driving pulse rationally is set solenoid valve 8 is driven; And it is corresponding through 7 rotations of solenoid valve 8 control disks; The disk 7 that rotates drives tooth bar 5 through connecting rod 6 and pumps, and is rotated through tooth bar 5 control main shafts 2 at last, reaches adjustment solar energy photovoltaic panel 1 azimuthal target.Fall along with the east of one day sun rises the west, control and tackle mutually solenoid valve 8 through controller paired pulses generator and carry out intermittence and drive, adjustment solar energy photovoltaic panel 1 towards, guarantee the light-receiving area maximization of solar energy photovoltaic panel 1.During actual the use,, just can adjust the anglec of rotation and the rotational time of solar energy photovoltaic panel according to the sun altitude data setting pulse control electromagnetic valve that precomputes.
In the actual use, solar energy photovoltaic panel 1 can be made into shapes such as rectangle, circle and ellipse as the case may be; Main shaft 2 passes through Bearing Installation on electric pole 3, and contacts with driving mechanism 4 interior tooth bars 5; Driving mechanism 4 comprises tooth bar 5, connecting rod 6, disk 7 and solenoid valve 8, through suitable solenoid-driven pulse is set, makes main shaft 2 by the predetermined angular rotation, changes the position angle of solar energy photovoltaic panel.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any restriction, every technical spirit changes any simple modification, change and the equivalent structure that above embodiment did according to the present invention, all still belongs in the protection domain of technical scheme of the present invention.
