Abstract

The utility model is a screw-dial automatic declination following apparatus which makes the angle between a lighting surface of a particle carrying frame and the earth's axis at any day equal to the declination angle of the sun in the day. The utility model can make the energy collection pipe arranged at due south and north receive the optimum exposure of the sun, and change an automatic sun follower with a single polar axis into an all-direction automatic sun follower with double polar axis. The utility model has the advantages of reliable and accurate tracking and low cost without the need of special motor to drive. The apparatus comprises a screw and nut mechanism, a slide block which can move along the particle carrying frame, a bi-directional single driver and a dynamic dial rod. The automatic declination following apparatus is realized by means of the dial of the dynamic dial rod to a rocking handle of the bi-directional single driver when an hour angle automatic following system returns to the east. The utility model also provides an automatic double-return apparatus.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail explanation.

Declination support 2 among the Accompanying drawing 1 and Fig. 2 are respectively front view of the present utility model and vertical view. figure (the declination support is for realizing the various in addition carriers of parts of declination motion) is consolidated in main shaft 1; Luggage carrier 4 is articulated in declination support 2 by declination axis 3; Nut gear 14 all is flexibly connected with declination support 2 with the base gear 13 of two-way patrilineal line of descent with only one son in each generation device; By its support; The slide block 5 that screw rod 11 upper ends connect can be along the luggage carrier translation; When the hour angle axle is subjected to external force to return east 1 every day; The rocking handle 9 of two-way patrilineal line of descent with only one son in each generation device is subjected to the stirring the power of revolting simultaneously return spring 15 of power driving lever 10 and turns to an angle; Because between rocking handle 9 and the base gear 13 the ratchet drive connection is arranged; So when rocking handle 9 is stirred by power driving lever 10; May drive base gear 13 rotates; Also not directly driven gear 13 rotations; In such cases; When rocking handle 9 is subjected to dial end; Return spring 15 resets because spurring rocking handle 9; So must drive the base gear rotation; So; In any case; Rocking handle is subjected to dial the gear 13 that all will drive two-way patrilineal line of descent with only one son in each generation device turns to an angle; The nut gear 14 that is meshed is also turned to an angle; So make 11 liters of screw rods or fall a distance; Screw rod makes luggage carrier rotate an angle around declination axis by slide block; This angle equates with the angular displacement of declination motion of the sun on the same day; When going to the winter solstice; Winter driving lever 6 so that the commutation handle 7 that together rotates with base gear 13 oppositely turn to; After this; When rocking handle 9 is stirred by power driving lever 10; Base gear 13 and nut gear 14 have all changed rotation direction; Thereby screw rod becomes rising by original decline; To during the summer solstice; Summer driving lever 12 make commutation handle 7 Rotation With Changing to; When the rocking handle 9 of two-way patrilineal line of descent with only one son in each generation device is stirred by power driving lever 10; Screw rod moves downward; As long as calculate and adjust group angle that is subjected to of rocking handle 9, the reciprocating one-period of screw rod and revolution of the earth cycle are equated. Realize the declination automatic sun tracing of luggage carrier 4.

Realize two to returning, though easy power saving again is not exclusively reliable sometimes with mechanical driving lever.

Fig. 3 and Fig. 4 are electromagnetism two to one of embodiment of return mechanism, promptly in Fig. 3, inhale the seat of honour 16 and be divided into two, be fixed on the pedestal of two-way patrilineal line of descent with only one son in each generation device 19, fixedly magnetic source 18 is permanent magnets, is fixed on to inhale the seat of honour 16, moving magnetic source 17 is solenoids, be fixed on commutation handle 7, constitute and inhaled parts, their installation situation in whole device as shown in Figure 4.In Fig. 4, snail fan, worm screw and weight are represented in double dot dash line successively, summer support 22 is fixed on the snail fan, summer electrode 21 is a support and being connected with it with it, summer contact 20 is fixed on the commutation handle, Fig. 4 represents that summer contact 20 contacts with summer electrode 21 and makes solenoid 17 produce the magnetic figured stones, and Fig. 3 represents that it is with speed V permanent magnet N utmost point benz upward.After the commutation, the power transmission direction of rocking handle 9 will change.Winter electrode 25 is fixed on snail fan lower end.Winter contact 24 is fixed on worm screw, and worm screw is supported by luggage carrier fishplate bar 23.

So-called herein two-way patrilineal line of descent with only one son in each generation device is meant overrunning clutch mechanism, for example the ratchet transmission mechanism of box spanner and so on.

Though the device of walking about of present embodiment is an example with snail fan worm screw, also be applicable to the walk about situation of device of bolt and nut fully.

The utility model has a lot of use, except making the polar mounts of forming by hour angle single shaft sun-following system become twin shaft with day with a day machine, if solar water heater vacuum tube or heat-pipe vacuum-tube is when being contained on the luggage carrier described in the utility model, can be fixed on the declination support on the stationary gantry, drive one time rocking handle 9 every day with electromagnet, or power driving lever 10, because of garden shape pipe has the natural uniaxiality tracking of east-west direction, be the twin shaft automatic sun tracing so will become it.

Advantage of the present utility model is: (1) is simple in structure, and cost is low; (2) reliable in action, accurate; (3) Do not want ad hoc motor-driven, save cost and the energy.
