A solar heat collecting system includes a collecting mirror (1), a receiver (3), an electrical control unit for controlling the collecting mirror (1) to track the sun, a projection mirror disposed coaxially and integrally with the collecting mirror and the focus of which is coincident with that of the collecting mirror (1), a through hole (11) disposed at the collecting mirror (1) and the size of which is larger than that of the light spot of the projection mirror (2) and far smaller than the through hole of the collecting mirror (1), and a reflecting mirror (5) disposed at the side of the collecting mirror (1) opposite to the projection mirror (2). The reflecting mirror (5), the collecting mirror (1), and the projection mirror (2) form a mirror assembly, and the receiver (3) is fixedly disposed at the extending direction of the primary optical axis line of the reflecting mirror (5). A first motor, disposed at the primary optical axis line for driving the whole mirror assembly to rotate around the center of the reflecting mirror, is connected to the electrical control unit and runs under control thereof. The solar heat collecting system can effectively improve solar concentration ratio. |
