Dish-sort concentrating solar thermal energy technology is presently the most effective solar power era method with a most efficiency of 29.4%. It is anticipated that sooner or later, industrialized massive-scale software can be realized, and iTagPro smart device its cost can be greatly diminished, and it will turn into a new vitality power era that competes with the cost of giant-scale conventional power plants. 5-a hundred KW, in order that it might notice separate distributed power technology, and it can also perform massive-scale energy generation by multiple single-unit networks. The appliance vary may be very wide, and it is at present the global photo voltaic energy technology. 01 and a two-axis tracking device, and the two-axis tracking device can understand the horizontal rotation and the tilting motion of the concentrating machine 01, so that the concentrating machine 01 can simultaneously track the sun's place and Height adjustments. 041 is connected to the connecting plate 02 of the slewing support through a joint bearing.

03 is vertical, in order that the horizontal rotation of the concentrating machine may be realized when the slewing bearing 03 rotates (that is, the rotation concerning the vertical axis, the vertical axis is the axis of the slewing help), iTagPro product and iTagPro support the screw of the screw jack may be expanded and contracted. Achieve the pitching motion of the concentrating system. FIG. 1) is just not located on the pitch rotation axis, and iTagPro product the geometric symmetry point of the condensing disk (the horizontal dotted line in FIG. 1 and The intersection of the vertical dashed line always deviates from the pitching movement rotation axis as the pitch movement modifications, iTagPro product so the construction increases the issue and instability of the center of gravity configuration. It is an object to supply a concentrating disc system including the above-described two-axis tracking device. The intersection of the axis of the rotating shaft and the axis of the slewing bearing coincides. The middle of gravity of the disc system is always on the axis of the spindle.

Because the above-described two-axis tracking device has the above technical results, the photo voltaic concentrating disk system having the two-axis tracking device should even have corresponding technical results. FIG. 3 is a schematic structural diagram of a concentrating optical disc system in response to an embodiment of the present invention. FIG. Four is a schematic structural diagram of one other state of a concentrating optical disc system in keeping with an embodiment of the current invention. FIG. 5 ng ring 2 are perpendicular to one another and intersect one another. 6 is fastened on the truss 7, and the telescopic member 6 has a telescopic rod 61 that can be telescoped.
