Effect of the present invention is: sun tracker apparatus of the present invention, be the hydraulic actuator of two trackers directly to be transmitted by fluid pressure type be linked together, like this, when one of them solar energy equipment with sun when operation, nature moves with the sun another solar energy equipment under the situation of any additional control need not.If solar energy equipment and (or) parts of the alterable height of one of them tracker are used as the counterweight of the storage power of another solar energy equipment, so, this energy consumption by the system that two trackers are formed just can be especially little, and this brings lot of advantages especially can for heavy solar energy equipment.
To be described in detail the present invention by accompanying drawing at this:
Illustrate:
The unit that Figure 1A and Figure 1B are made up of two single shaft sun trackers constitutes the structural representation of sun tracker apparatus of the present invention.
The unit that Fig. 2 is made up of two biaxial solar trackers constitutes the structural representation of sun tracker apparatus of the present invention.
The system that Fig. 3 A and Fig. 3 B are made up of three unit constitutes the structural representation of sun tracker apparatus of the present invention.
Figure 1A, 1B represents tracker I a, an I b respectively, it has a pillar 2,20 that moves in guide pipe 4,22, solar energy equipment 1 of the last end bearing of this root pillar, its lower end is then supported by the cylinder 12,27 of a single effect, this tracker is according to hydraulic pressure balance principle, be coupled to each other together by the transmission of fluid pressure type power and the counterweight as energy storage device, this hydraulic pressure balance is made up of 12,27, the hydraulic tubes 13,14 of cylinder of a single effect and the cylinder 12 ', 27 ' of another single effect.At this, the power transmission of an also available machinery replaces the hydraulic coupling transmission.The tracker II a that solar energy equipment is identical with another structure, the parts of the alterable height of II b are as counterweight.Tracker is that so mutual lotus root is closed, and when the pillar 2,2 ', 20,20 ' of one of two trackers was in the decline process, meanwhile another then was in the uphill process, and, the rotation direction unanimity of two solar energy equipments.According to Figure 1A, can make the tracker that has vertical rotation axis realize rotating in the same way by the opposite gathering sill 16 and 16 ' of the hand of spiral (helicla flute 16,16 ' has pin 15,15 ' in the drawings).This spiral guide slot moves the straight line of pillar and is transformed into corresponding rotational motion.According to Figure 1B, the rotation in the same way that has the tracker of horizontal rotating shaft can realize by bar 21,21 ', these bars are connected with the supporting structure 28,28 ' of solar energy equipment by a turning joint in the different side of tie point on the one hand, and these tie points are connected pillar 20,20 ' with supporting structure 28,28 ' accordingly; On the other hand, bar 21,21 ' can be swung, and with guide pipe 22,22 ' or another fixing point link to each other.Another kind of version can be: bar 21,21 ' is not swung, and guide pipe 22,22 ' can be swung, and is fixed simultaneously on the ground; Perhaps, can pillar 20,20 ' and supporting structure 28,28 ' between add an additional bar of swinging respectively, simultaneously, guide pipe 22,22 ' and bar 21,21 ' do not move.Two solar energy equipments are just in a direction motion (for example daytime), because the solar energy equipment and the parts of alterable height that have a tracker I a (Figure 1A) just can make two solar energy equipments move to another way (for example night) than the solar energy equipment weight of another tracker II a by a pump 26.Shown in Figure 1B, the control of tracker realizes by moving a single weight 29; This weight links to each other with the supporting structure 28 of tracker I b, also can have driven by power.At this, the then natural interlock of another tracker II b is correct.
Two two axis trackers of closing of phase lotus root each other shown in Figure 2, they are combinations of the uniaxiality tracking device described among Figure 1A and Figure 1B.An interior pillar 20 can move in the pillar 2 outside one, and this outer pillar moves in guide pipe 4.Outside each the piston 11,11 ' of pillar around individual annulus 18,18 ' is arranged, piston interconnects by hydraulic tube 14, and by hydraulic tube 25,25 ' with one accordingly, belong to interior pillar 20,20 ' cylinder 27,27 ' links to each other.Annular space 18,18 ' minimum length are equivalent to the haul distance of pillar 2, and all there is piston packing 23 its above and below.Like this, transmit 12,13 in the hydraulic coupling between the pillar 2,2 ', 12 ' and pillar 20,20 ' between hydraulic coupling transmission 27,25,18,14,18 ', 25 ', 27 ' all be separated from each other in each position of pillar.Bar 21,21 ' sunwise can device rotation direction be rotatably connected to supporting structure 28,28 ' and outer pillar 2,2 ' on.
Fig. 3 A and Fig. 3 B represent the system that is made up of three unit a, b, c, and wherein, each unit comprises two trackers according to Figure 1A and Figure 1B.Here, pillar 2,2 ', 20,20 ' is supported by beidirectional cylinder 17,17 ', 37,37 '.Unit a, b, c are connected with each other by first chamber of beidirectional cylinder, and at this, first chamber of the tracker I of a unit links to each other by a hydraulic tube 19,39 with first chamber of the tracker II of another unit respectively.For example: described as Figure 1A and Figure 1B, only need tracker of control, every other tracker will rotate according to correct direction naturally.Generally speaking, the gross weight of the motion parts of all the tracker I among Fig. 3 A is greater than the gross weight of the motion parts of all tracker II.
