| 摘要 |
<p>The invention relates to a structure having a torsion lattice girder for a parabolic trough solar collector, consisting of: a torsion girder (23) having a square cross-section, which in turn includes: frames (1) at both ends that transmit torque, enable connection with another adjacent collector and support the rotational shaft (2) of the collector; a girder body formed by four struts (3); X-braces (16); and rigid welded assemblies (20) that are attached onto the two upper struts (3) of the girder to bear each supporting means (18) for the absorber tube (19). Said structure further consists of cantilever supporting means (7) anchored to the girder (23) and on which belts (5) are placed, in which belts the clamps (6) that hold the reflectors are located; and supporting means (18) for the absorber tube (19) that are joined to the struts (3) by means of the rigid welded assemblies (20).</p> |
