Filed: 2020-02-11
Abstract: It is t an object of the present invention to provide an improved smart sun tracking systems that are expanding in three different directions, configured with multiple two-axis sun- trackers integrated with various single or step-aside double layers of hybrid Dual faces PV thermal panels to only two swiveling couplers in different directions with two driven main cables in closed loops (North-South and East-West), define the 4-dimension structure, and strong enough to withstand wind loading and the like without the structural reinforcement here to for required. Another object of the present invention is to provide an improved sun tracking systems for solar energy radiation receivers, which can be built from a minimum number of inexpensive parts and minimum maintenance. Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the prior art upon examination of the following or may be learned by application of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims. two electric motorized pulley attachments, connecting the closed loops cables to each 3- solar energy radiation receivers' to sub-assembly support beam, mounted on mast pillars at different lengths allow to provide a wide range of adjustments, i.e. wherein the 3- units of solar energy radiation receivers, reversing directions according to the seasons and when is needed. A clockwise and counter-clockwise electric motorized pulley, connected to dual direction main cables design is biased to maintain differential positions. When underneath the 3- units of solar energy radiation receivers connected central support beam which connected to swivel coupler and a pair of differential locations hooks. The smart sun-trackers system comprising multiple two-axis sun-trackers connected with cables in closed loops, provides required forms of multiple at least one or more 3- units of solar energy radiation receiver's mounted above sub-support beam assembly, when the cables are moving back and forth. The mechanism includes an electric motorized pulley shaft rotating in a different direction parallel to the cable portion to which the mechanism is attached. Because the cables connected in 2 different locations attached to the central support beam, allow the central main mast pillars swivel with the same cables length displacement following the movements which occur between all differential step-aside main mast pillars, respectively to North-South positions, providing the necessary solar energy radiation receiver adjustment desired. The same principles works with the East-West differential movements' when main mast pillars step-aside relative to solar energy radiation receivers sub-assembly modules of multiple units of 3-solar energy radiation receivers as described above. The solar energy radiation receivers could be of the; solar flat-plate type, or other configurations, such as various single or step-aside double layers of hybrid Dual faces PV thermal panels.
