The specific embodiment
Referring to Fig. 1 and Fig. 2, in the present embodiment slot type twin shaft to day tracking heat collection device structure be set to: follow the tracks of power sources for two and be respectively truss reducing motor 1 and the reducing motor 7 of bowing that inclines; Truss reducing motor 1 and the inclining reducing motor 7 of bowing drives the rotation of slot type mirror pivoted frame 9 and north and south pivoted frame 8 respectively;
As shown in Figure 3, thermal-collecting tube 2 is fixed on left socle 15 and the right support 16, and heat-conducting medium pipe 25 places thermal-collecting tube 2; Solar azimuth tracker 4 is installed in north and south pivoted frame 8 upper ends; Following the tracks of switch board 3 is arranged on the base 6; Solar azimuth tracker 4, incline bow reducing motor 7 and truss reducing motor 1 with follow the tracks of switch board 3 and be connected by electric wire.
As shown in Figure 4, the bow reducing motor 7 of inclining is connected with north and south pivoted frame 8 by key 20, north and south pivoted frame 8 and the inclining reducing motor 7 of bowing is installed on the bearing block 24, and bearing block 24 is provided with radial ball bearing 21, bearing gland 22 and bearing end cover plate 23, and bearing block 24 is fixed on the base 6 by screw;
As shown in Figure 3, truss reducing motor 1 is fixed on by securing cover plate 13 on the left bearing plate 14 of north and south pivoted frame 8 one ends, is connected by flat key with left rotary shaft 12; Be respectively equipped with left rotary shaft 12, right spindle 19 on the left bearing plate 14 at north and south pivoted frame 8 two ends and the 17 right bearing plates; Left rotary shaft 12 is through left bearing 10, plane bearing 11 location, and right spindle 19 is through right bearing 18 location; Fixedly connected with right spindle 19 with left rotary shaft 12 in slot type mirror pivoted frame 9 two ends; Slot type reflective mirror 5 is fixed on the slot type mirror pivoted frame 9 by screw.
Existing solar light automatic tracking controller mainly contains two kinds: one is to use a light sensor and Schmidt trigger or monostable flipflop, constitutes light-operated Schmidt trigger or light-operated monostable flipflop and controls stopping, changeing of motor; Two are to use two light sensors and two comparators to constitute the rotating that two light-operated comparators are controlled motors respectively.Because throughout the year, sooner or later and noon surround lighting and the strong and weak excursion of sunlight all very big, so above-mentioned two kinds of controllers are difficult to make the big sun energy round-the-clock tracking sun of the receiving system four seasons, and solar energy time tracking controller is to realize controlling by the position at the sun and earth relative motion place now, be on the earth certain longitude and latitude by calculating the relative angle with the sun, the movement locus of the sun and the earth is producing faint variation, so this type of shortcoming of following the tracks of the control existence is followed the tracks of accurately low exactly, now based on time control, light-operated be calibrated to auxilliary, be that time control does not allow to rerun, heat collector navigates to Position Approximate by time control, then by light-operated accurate calibration.
Control procedure:
Real-time tracking by 4 pairs of sun of solar azimuth tracker, elevation angle variation and the horizontal direction of the sun are changed conduction to following the tracks of switch board 3, follow the tracks of switch board 3 and send to follow the tracks of and adjust signal, drive truss reducing motor 1 and the reducing motor 7 of bowing of inclining is done to the day pursuit movement.Truss reducing motor 1 drives left rotary shaft 12 and transmits power to slot type mirror pivoted frame 9, slot type mirror pivoted frame 9 drive the slot type mirrors do between east and west to tracking rotate; The bow reducing motor 7 of inclining drives north and south pivoted frames 8, and north and south pivoted frame 8 drives slot type mirror pivoted frames 9, slot type reflective mirror 5, thermal-collecting tube 2 and does North and South direction and follow the tracks of and rotate.Truss reducing motor 1 and the inclining reducing motor 7 of bowing drives the tracking of thing, north and south both direction respectively, make the motion mutually noninterfere of thing, north and south both direction, superpose by the motion of north and south pivoted frame to thing, north and south both direction, form comprehensive to the day high precision tracking.
East-west direction control: it is 0.01rpm that truss reducing motor 1 is set rotating speed, and then the angle that turns over of east-west direction per minute is 3.6 °, returns the east time: 50 minutes.
North and South direction control: reducing motor 7 rotating speeds of bowing of inclining are 0.02rpm, 0-90 ° at control inclination angle, north and south, resetting time: 25 minutes.
The structure shape tracking accuracy of present embodiment can reach 0.05 °, is that its solar thermal utilization rate of example is 90%-95% with the glass reflector.
