Sun tracing device

Abstract

A sun tracing device includes a power unit having an elevating element, a supporting plate carrying a photoelectric transformation unit, and an adjusting unit coupled to the power unit and the supporting plate. The power unit is used to lift/lower the adjusting unit, so that the adjusting unit can rotate and/or lift/lower the supporting plate.

1 . A sun tracing device, comprising:
 a power unit having at least one elevating element;   a supporting plate carrying a photoelectric transformation unit; and   an adjusting unit connected to the elevating element and the supporting plate, wherein the power unit is used to lift/lower the adjusting unit, and the adjusting unit changes a tilt angle of the supporting plate.   
   
   
       2 . The sun tracing device according to  claim 1 , wherein the power unit is further connected to a containing unit substantially, and the power unit and the containing unit contain a fluid flowing between the power unit and the containing unit. 
   
   
       3 . The sun tracing device according to  claim 2 , wherein the power unit and/or the containing unit are further connected to an external power unit, and the external power unit provides a power for driving the fluid flowing from the containing unit to the power unit. 
   
   
       4 . The sun tracing device according to  claim 2 , wherein the fluid is selected from liquid, gas, and their combination. 
   
   
       5 . The sun tracing device according to  claim 2 , wherein a valve is disposed between the power unit and the containing unit, and the valve controls a flowing state of the fluid flowing from the power unit to the containing unit. 
   
   
       6 . The sun tracing device according to  claim 1 , wherein the adjusting unit further comprises:
 a connecting element connected to the elevating element; and   at least three shaft arms coupled to the connecting element and the supporting plate, wherein each of the shaft arms has at least one end located on the same plane and connected to a surface of the supporting plate.   
   
   
       7 . The sun tracing device according to  claim 6 , wherein the shaft arms are extensible and/or compressible. 
   
   
       8 . The sun tracing device according to  claim 6 , wherein the movement of the shaft arms includes a linear movement or a rotation. 
   
   
       9 . The sun tracing device according to  claim 1 , further comprising:
 a wind protection unit connected to the power unit and the adjusting unit for forcibly enabling the power unit and the adjusting unit if a wind speed reaches a preset value.   
   
   
       10 . The sun tracing device according to  claim 1 , further comprising:
 a sensing unit disposed on at least a periphery and/or a back surface of the supporting plate and/or the photoelectric transformation unit for controlling the adjusting unit so as to activate the adjusting unit.   
   
   
       11 . The sun tracing device according to  claim 10 , wherein the sensing unit is a photoelectric sensing unit. 
   
   
       12 . The sun tracing device according to  claim 1 , wherein the photoelectric transformation unit is a solar panel. 
   
   
       13 . The sun tracing device according to  claim 12 , wherein the solar panel is a concentrating solar panel or a flat solar panel.
