Rigid and flexible mixed supporting device of solar parabolic concentrating heat collector

The utility model belongs to the technical field of solar collection and relates to a rigid and flexible mixed supporting device of a solar parabolic concentrating heat collector. An integrated frame consists of a main beam, main sections and a main rope between the main sections, an installation matrix of a parabolic lens is provided by a pre-tightening steel rope structure which is formed by combining an auxiliary rope and a positioning rope, an automatic tensioning compensation device is arranged inside a steel rope and used for compensating the deformation of a supporting mechanical structure caused by environment change, and a plurality of concentrating units are connected in series and share the main sections. By structural topological optimization, rigid and flexible mixed supporting structure parameters are obtained, and a material performance is fully realized, so few materials are required by the supporting mechanical structure of the solar concentrating heat collector, the rigid and flexible mixed supporting device is light in weight and low in cost, and the strength and rigidity of the device meet using requirements.
