Abstract
The invention belongs to the technical field of tower-type photo-thermal power generation, and particularly relates to a supporting frame for a reflecting mirror of a tower-type photo-thermal power station. The gravity of a mirror surface rack assembly and the gravity of a sub mirror assembly are concentrated on two supporting shafts through two bases, and then transmitted to the connecting position of a stand column and a pivoted piece. The two bases form two supporting parts, and the two supporting parts are relatively stable in position in the vertical direction in the working process. The two supporting parts bear the gravity respectively and cannot be changed greatly along with pitching motion or because of encountering strong wind, so that structural stability is good and reflecting precision is guaranteed. Under the condition that the reflecting precision is guaranteed, it is expected that the mounting area of the mirror surface rack assembly can reach 200 square meters, a supporting frame with larger area even can be constructed, and thus more sub reflecting mirrors can be mounted. In addition, steel consumption of unit reflecting area is lowered, the number of integral control systems in a mirror field is reduced, processing, mounting and debugging are simplified, and unit construction cost is greatly lowered.
