Solar rooftop

Abstract

Provided herein is a solar rooftop, comprising a prop having a crossbeam; a plurality of hollow solar collector tubes parallel disposed on the prop; a waterproof film contacted with the hollow solar collector tubes; a plurality of glass tubes parallel disposed on the waterproof film; and a glass plate disposed on the glass tubes; wherein the glass tubes are disposed between two adjacent vacuum collector tubes. The solar rooftop of the invention has high transparency, good heat insulation, heat accumulation, heat retention and sealing performance, long lifetime, and an automatic temperature adjustment function.

       3 . The solar rooftop of  claim 2  further comprising a pad ( 7 ) disposed on the crossbeam of the prop ( 1 ), wherein the pad ( 7 ) improves intensity of solar radiation at the hollow solar collector tubes ( 2 ). 
   
   
       4 . The solar rooftop of  claim 3 , further comprising a pressing plate ( 14 ) disposed on the pad ( 7 ). 
   
   
       5 . The solar rooftop of  claim 4 , further comprising a nail ( 13 ) passing through the pressing plate ( 14 ) and being received in the pad ( 7 ), so as to fix the pressing plate ( 14 ) to the pad ( 7 ). 
   
   
       6 . The solar rooftop of  claim 1 , wherein the glass tubes ( 4 ) are all-glass vacuum collector tubes. 
   
   
       7 . The solar rooftop of  claim 6 , further comprising a pad ( 7 ) disposed on the crossbeam of the prop ( 1 ) and operating to improve intensity of the glass tube ( 4 ). 
   
   
       8 . The solar rooftop of  claim 7 , further comprising a pressing plate ( 12 ) disposed on the pad. 
   
   
       9 . The solar rooftop of  claim 8 , further comprising a fixing device ( 10 ) passing through the pressing plate ( 12 ) and being received in the pad ( 7 ), so as to fix the pressing plate ( 12 ) to the pad ( 7 ). 
   
   
       10 . The solar rooftop of  claim 9 , wherein the pressing plate ( 12 ) is concavely-shaped. 
   
   
       11 . The solar rooftop of  claim 1 , wherein the glass tubes ( 4 ) comprise a plurality of hollow glass tubes and all-glass vacuum collector tubes disposed alternately. 
   
   
       12 . The solar rooftop of  claim 1 , wherein the glass tube ( 4 ) is received in an upper gap formed between two adjacent hollow solar collector tubes ( 2 ). 
   
   
       13 . The solar rooftop of  claim 12 , wherein the glass tube ( 4 ) is contacted with an outer wall of the two adjacent hollow solar collector tubes ( 2 ) via the waterproof film ( 3 ). 
   
   
       14 . The solar rooftop of  claim 13 , wherein an outer diameter of the glass tube ( 4 ) is greater than a distance between two adjacent hollow solar collector tubes ( 2 ). 
   
   
       15 . The solar rooftop of  claim 1 , further comprising a pad ( 7 ) disposed on the crossbeam of the prop ( 1 ) and operating to improve intensity of the glass tube ( 4 ). 
   
   
       16 . The solar rooftop of  claim 14 , further comprising a pressing plate ( 9 ) disposed on the pad ( 7 ). 
   
   
       17 . The solar rooftop of  claim 16 , further comprising a fixing device ( 8 ) passing through the pressing plate ( 9 ) and being received in the pad ( 7 ), so as to fix the pressing plate ( 9 ) to the pad ( 7 ). 
   
   
       18 . A solar rooftop, comprising
 a plurality of hollow solar collector tubes ( 2 );   a plurality of glass tubes ( 4 );   a waterproof film ( 3 ); and   a glass plate ( 5 );   
     wherein
 the hollow solar collector tubes ( 2 ) are disposed in parallel to one another; 
 the glass tubes ( 4 ) are disposed in parallel to one another; 
 the hollow solar collector tubes ( 2 ) are disposed in parallel to the glass tubes ( 4 ); 
 the waterproof film ( 3 ) separates the hollow solar collector tubes ( 2 ) from directly contacting the glass tubes ( 4 ); 
 the distance between any two adjacent solar collector tubes is not greater than S; 
 the outer diameter of the glass tubes ( 4 ), Φ 0 , is greater than S; and 
 each the glass tube ( 4 ) is disposed on top of two adjacent solar collector tubes ( 2 ).
