The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of solar real-time tracing apparatus, comprise base support 1 and solar attachment 2, the two ends of base support 1 have been wholely set connecting rod 11 respectively, respectively be provided with a bearing 12 on each connecting rod 11, solar attachment 2 comprises solar panel 21 and is used for fixing the mounting bracket 22 of placing solar panel 21, solar panel 21 and the fixedly connected mode that can adopt existing any maturation being connected of mounting bracket 22.Be connected with the rotating shaft 23 of south-north direction on the middle position of mounting bracket 22, the two ends of rotating shaft 23 are connected on the connecting rod 11 by bearing 12 respectively, mounting bracket 22 is installed on the base support 1 by rotating shaft 23 and bearing 12, like this mounting bracket 22 just can be in base support 1 be that the center is rotated with rotating shaft 23.
An outside side is fixedly connected with headstock 3 on the connecting rod 11, offer a shaft hole (not shown) on the headstock 3, one end 231 of rotating shaft 23 passes shaft hole and is connected with headstock 3, be provided with shaft gear 4 in the headstock 3, be arranged on shaft gear 4 belows reciprocating stroke switch 5, drive motors 6, have the reduction box 7 of a stable drive ratio and the worm screw 8 of matching with shaft gear 4.One end 231 of rotating shaft 23 is provided with gear pin 232, and shaft gear is provided with cotter way 43, and gear pin 232 embeds in the cotter way 43, can drive rotating shaft 23 rotations like this when shaft gear 4 rotations; Shaft gear 4 is provided with and is used for and reciprocating stroke switch 5 contacted first plectrum 41 and second plectrums 42, the position of the position of first plectrum 41 and second plectrum 42 is symmetrical, when shaft gear 4 running make first plectrum 41 or second plectrum 42 just arrives below the time, first plectrum 41 or second plectrum 42 can just be stirred reciprocating stroke switch 5.Be connected with the power line 9 that is used to insert the external power source (not shown) on the reciprocating stroke switch 5, one end of power line 9 is connected with drive motors 6 by reciprocating stroke switch 5, the rotating shaft of drive motors 6 is connected with the power shaft of reduction box 7, can drive the mutual transmission of each gear (not shown) in the reduction box 7 like this when drive motors 6 runnings, the output shaft of reduction box 7 is connected with worm screw 8.
Reciprocating stroke switch 5 and reduction box 7 all adopt existing technology in this specific embodiment.In order to reach the real-time tracking sun, the rotary speed that must guarantee solar panel 21 is identical with the speed that liter west, sun east falls, so rotating speed of drive motors 6, the transmission of the reduction box 7 when tooth number of shaft gear 4 is wanted suitably, promptly after the rotating speed of drive motors 6 is determined, can select reduction box 7 and shaft gear 4 according to (the rotating speed * of drive motors 12 hours)/(the tooth number of gearratio * shaft gear)=1/2, as long as make that the rotating speed of rotating shaft is 0.0006944 rev/min, the real-time tracking purpose of final realization, rotating speed as drive motors 6 is 1000 rev/mins, if turn round 12 hours, then can select gearratio is that 24000: 1 reduction box and tooth number are 60 shaft gear.Reciprocating stroke switch 5 effect that cooperates that contacts with first plectrum 41 or second plectrum 42 in the present invention mainly is to make solar panel 21 keep the back and forth rotation of 180 degree, rather than 360 degree rotations, can effectively avoid solar panel 21 phenomenon of the power supply output line (not shown) of solar panel 21 when 360 degree rotations, to occur twining like this because of rotation.Select for use worm screw 8 and shaft gear 4 to match in the present invention and carry out transmission, this structure can make the kinetic force of drive motors 6 pass to the mounting bracket 22 of fixed solar power generation plate 21 smoothly, if worm screw 8 is used common gear instead, though can realize the purpose of following the tracks of, but under the influence of extraneous wind-force, ordinary gear may drive solar panel 21 counter-rotatings, thereby will influence the rotating speed of drive motors 6, causes tracking error the most at last.
With the 6:00 AM is starting point, the sun is in the ground level in east, this moment, original state of the present invention was that solar panel 21 is vertical with the horizon, the sensitive surface of solar panel 21 is towards east, this moment, first plectrum 41 just contacted with reciprocating stroke switch 5, the feasible opposite current that is input to drive motors 6, thereby make drive motors 6 turn clockwise, the rotating speed of drive motors 6 outputs is 24000: 1 reduction box 7 deceleration adjustment by gearratio, rotating speed after slowing down is passed to shaft gear 4 by worm screw 8, the shaft gear 4 drive solar panels 21 that are connected in the rotating shaft 23 turn clockwise, when running after 6 hours during just to 12, the sun is under the vertical irradiation situation, because the rotating speed of drive motors 6 is 1000 rev/mins, so this moment drive motors 6 corotation 360000 change, by gearratio be 24000: 1 reduction box 7 back worm screw 8 corotation 15 change, be the shaft gear 4 of 60 teeth again by the tooth number, final solar panel 21 rotates 1/4 commentaries on classics has just changeed 90 degree, still keeps vertical with the sun; Again when running after 6 hours the time just at 18 in evening, the sun is on the ground level in west, this moment, drive motors 6 changeed 360000 commentaries on classics again, by gearratio is that 24000: 1 reduction box 7 back worm screws 8 have changeed 15 again and change, pass through the shaft gear 4 of 60 teeth again, final solar panel 21 rotates 1/4 commentaries on classics has again just changeed 90 degree, the solar panel 21 of this moment is vertical with the horizon again, just the sensitive surface of solar panel 21 is exposed to the west, second plectrum 42 on the shaft gear 4 is just stirred reciprocating stroke switch 5 at this moment simultaneously, make that the electric current that is input to drive motors 6 is opposite again, drive motors 6 is rotated counterclockwise, and drive solar panel 21 and be rotated counterclockwise, meet next sunrise.
Because the present invention only used a rotating shaft 23, belong to uniaxiality tracking, therefore in using process of the present invention, should according to the different latitude of different regions adjust towards south to the elevation angle, elevation angle theta as shown in fig. 1.
