Detailed description of the invention
See Fig. 1 and Fig. 2, in the present embodiment slot type biaxially day tracking heat collection device vibrational power flow be: 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 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 right support 16, and heat-conducting medium pipe 25 is placed in thermal-collecting tube 2; Solar azimuth tracker 4 is arranged on north and south pivoted frame 8 upper end; Tracing control cabinet 3 is arranged on base 6; Solar azimuth tracker 4, the reducing motor 7 of bowing of inclining are connected by electric wire with tracing control cabinet 3 with truss reducing motor 1.
As shown in Figure 4, the reducing motor 7 of bowing of inclining is connected with north and south pivoted frame 8 by key 20, north and south pivoted frame 8 and inclining reducing motor 7 of bowing is arranged on 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 by screws on base 6;
As shown in Figure 3, truss reducing motor 1 is fixed on the left bearing plate 14 of north and south pivoted frame 8 one end by securing cover plate 13, is connected by flat key with left rotary shaft 12; Left bearing the plate 14 and 17 right bearing plate at north and south pivoted frame 8 two ends is respectively equipped with left rotary shaft 12, right spindle 19; Left rotary shaft 12 is located through left bearing 10, plane bearing 11, and right spindle 19 is located through right bearing 18; Slot type mirror pivoted frame 9 two ends are fixedly connected with right spindle 19 with left rotary shaft 12; Trough reflectors 5 is fixed by screws on slot type mirror pivoted frame 9.
It is use light sensor and Schmidt trigger or monostable flipflop that existing solar light automatic tracking controller mainly contains two kinds: one, forms light-operated Schmidt trigger or light-operated monostable flipflop to control the stopping of motor, to turn; Two is that use two light sensors and two comparators form the rotating that two light-operated comparators control motor respectively.Due to throughout the year, sooner or later and noon surround lighting and the strong and weak excursion of sunlight all very large, so above-mentioned two kinds of controllers are difficult to make the large sun energy receiving system four seasons round-the-clock tracking sun, and solar energy time tracking controller realizes controlling by the position at the sun and earth relative motion place now, namely 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 change, so the shortcoming that this type of tracing control exists is followed the tracks of accurately low exactly, now based on time control, light-operated be calibrated to auxiliary, namely time control does not allow to rerun, heat collector navigates to Position Approximate by time control, then by light-operated accurate calibration.
Control procedure:
By the real-time tracking of solar azimuth tracker 4 pairs of sun, the change of the elevation angle of the sun and horizontal direction change are conducted to tracing control cabinet 3, tracing control cabinet 3 sends tracking adjustment signal, drives truss reducing motor 1 and the reducing motor 7 of bowing of inclining does to day pursuit movement.Truss reducing motor 1 drives left rotary shaft 12 to transmit power to slot type mirror pivoted frame 9, and the tracking that slot type mirror pivoted frame 9 drives slot type mirror to do east-west direction is rotated; The reducing motor 7 of bowing of inclining drives north and south pivoted frame 8, and north and south pivoted frame 8 drives slot type mirror pivoted frame 9, trough reflectors 5, thermal-collecting tube 2 to do North and South direction and follows the tracks of and rotate.Truss reducing motor 1 and inclining reducing motor 7 of bowing drives the tracking of thing, north and south both direction respectively, make the motion of thing, north and south both direction non-interference, superposed by the motion of north and south pivoted frame to thing, north and south both direction, formed comprehensive to day high precision tracking.
East-west direction controls: truss reducing motor 1 setting speed is 0.01rpm, then the east-west direction angle turned over per minute is 3.6 °, returns the east time: 50 minutes.
North and South direction controls: reducing motor 7 rotating speed of bowing of inclining is 0.02rpm, controls inclination angle, north and south 0-90 °, resetting time: 25 minutes.
The structure shape tracking accuracy of the present embodiment can reach 0.05 °, for its solar thermal utilization rate of glass reflector for 90%-95%.
