SOLAR CONCENTRATOR, AND HEAT COLLECTION APPARATUS AND SOLAR THERMAL POWER GENERATION APPARATUS INCLUDING SAME

摘要

A center of gravity Q1 of a mirror structure 31, which has a plurality of mirrors 32, is located between the plurality of mirrors 32. A driving mechanism 40 that rotates the mirror structure 31 includes a first rotational shaft 52 that has a first rotational axis A1 as a central axis and is supported by a supporting base 80 to be rotatable, a first drive device 60 that rotates the first rotational shaft 52, a second rotational shaft 42 that has the mirror structure 31 fixed thereto, has a second rotational axis A2 which is orthogonal to the first rotational axis A1 as a central axis, and is mounted on the first rotational shaft 52 to be rotatable, and a second drive device 45 that rotates the second rotational shaft 42. The center of gravity Q1 of the mirror structure 31 is located in the first rotational shaft 52 and in the second rotational shaft 42.
