Patent ID: 8438790

Claim:
A support structure for a solar collector of a type used in cylindrical parabolic collectors to support a cylindrical parabolic reflector and an absorbing tube, comprising: a main bearing structure ( 1 ), the main bearing structure ( 1 ) further comprising two identical rectangular lattice grids ( 4 ); a plurality of laterally arranged support arms ( 2 ) adapted to support a plurality of parabolic mirrors ( 3 ), the support arms ( 2 ) being supported on the main bearing structure; wherein the two identical rectangular lattice grids ( 4 ) are arranged as a top rectangular lattice grid ( 4 ) and a bottom rectangular lattice grid ( 4 ), in a parallel and overlaying arrangement; wherein the two identical rectangular lattice grids ( 4 ) are linked together by four laterally-disposed mini-lattices ( 5 ) and by a plurality of external lateral tie bars ( 6 ) and internal diagonal tie bars ( 7 ); and wherein the main bearing structure ( 1 ) has, at both ends, by two end plates ( 11 . 12 ) that include a plurality of support points for legs anchored to a ground surface that give the solar collector the necessary rotation axis.
