Non-electrically-powered sun-tracking solar system

Abstract

A non-electrically-powered sun-tracking solar system has a shaft, a solar panel, two roll drivers, a roll transmitter, two pitch drivers and a pitch transmitter. The shaft has a lower shank and an upper shank pivotally mounted upon the lower shank. The solar panel is pivotally mounted on the upper shank. The two roll drivers are ecliptically and bilaterally attached to the solar panel. The roll transmitter pivotally connects the upper shank and the solar panel and communicates with the two roll drivers. The two pitch drivers are meridionally and bilaterally attached to the solar panel. The pitch transmitter pivotally connects the lower shank and the upper shank and communicates with the two pitch drivers. Uneven heating by sunlight activates the roll drivers to change pitch and roll of the solar panel with the roll transmitter and the pitch transmitter for improved efficiency.

1 . A non-electrically-powered sun-tracking solar system comprising
 a shaft comprising
 a lower shank; and 
 an upper shank pivotally mounted upon the lower shank; 
   a solar panel pivotally mounted upon the upper shank of the shaft and comprising a support surface;   two roll drivers ecliptically and bilaterally attached to the solar panel and each roll driver comprising
 a roll energy storage attached to the support surface of the solar panel and partially protruding from the solar panel; and 
 a medium stored in the roll energy storage and capable of converting into a gaseous state when heated; 
   a roll transmitter pivotally connecting the upper shank and the solar panel, communicating with the two roll drivers and capable of expanding and contracting when receiving the gaseous medium of the roll drivers for rotating the solar panel to face the sun;   two pitch drivers meridionally and bilaterally attached to the solar panel and each comprising;
 a housing attached to the support surface of the solar panel and comprising
 a protruding portion protruding from the solar panel; and 
 an opening defined on protruding portion; 
 
 a pitch energy storage received in the housing and positioned under the opening; and 
 a medium stored in the delinational energy storage and capable of converting into a gaseous state when heated; and 
   a pitch transmitter pivotally connecting the lower shank and the upper shank, communicating with the two pitch drivers and capable of expanding and contracting at receiving the gaseous medium of the pitch drivers for rotating the solar panel to face the sun.   
     
     
         2 . The non-electrically-powered sun-tracking solar system as claimed in  claim 1 , wherein
 the roll transmitter further comprises
 a hollow cylinder and comprising
 a top pivotally attached to the solar panel; and 
 an air chamber; and 
 
 a piston comprising
 a piston bottom pivotally attached to the upper shank; and 
 a roll plunger slidably mounted in the cylinder and dividing the air chamber of the cylinder into a first chamber and a second chamber respectively receiving the gaseous media from the two roll drivers. 
 
   
     
     
         3 . The non-electrically-powered sun-tracking solar system as claimed in  claim 1 , wherein
 the pitch driver further comprises
 a hollow cylinder hollow and comprising
 a top pivotally attached to the upper shank; and 
 an air chamber; and 
 
 a piston comprising
 a piston bottom pivotally attached to the lower shank; and 
 a pitch plunger slidably mounted in the cylinder and dividing the air chamber of the cylinder into a first chamber and a second chamber respectively receiving the gaseous media from the two pitch drivers. 
 
   
     
     
         4 . The non-electrically-powered sun-tracking solar system as claimed in  claim 2 , wherein
 the pitch driver further comprises
 a hollow cylinder hollow and comprising
 a top pivotally attached to the upper shank; and 
 an air chamber; and 
 
 a piston comprising
 a piston bottom pivotally attached to the lower shank; and 
 a pitch plunger slidably mounted in the cylinder and dividing the air chamber of the cylinder into a first chamber and a second chamber respectively receiving the gaseous media from the two pitch drivers. 
 
   
     
     
         5 . The non-electrically-powered sun-tracking solar system as claimed in  claim 1 , wherein each of the two roll drivers further comprises a sunshades attached upon the roll energy storage. 
     
     
         6 . The non-electrically-powered sun-tracking solar system as claimed in  claim 2 , wherein each of the two roll drivers further comprises a sunshade attached on the roll energy storage.
