Abstract:
1. A solar collecting and utilizing device, comprise: one or more paraboloidal light collecting mirrors, each having a paraboloidal open surface with a focus for collecting/converging the sunlight; one or more light guiders, each including a light guider mirror, having a focus, for receiving sunlight converged by a corresponding one of said paraboloidal light collecting mirrors and converting it into horizontal and substantially parallel light beams in desired direction; one or more curved surface condenser mirrors for receiving and converging the horizontal and substantially parallel light beams from said light guider; a solar storage and conversion device for storing/converting the solar energy converged by said curved surface condenser mirrors; and a solar tracking equipment for tracking automatically the sunlight so as to keep the opening surface of said paraboloidal light collecting mirrors substantially vertical to the sunlight; wherein, the focus of said light collecting mirrors superposes the focus of the corresponding light guider mirror; and wherein said light guider is hinged to the guider support, the lower part of said guider support is fixed to the light collecting mirror or a mirror basket; said light guider comprises a rotation axis in a direction of east to west, a mirror bracket which is hinged to the guider support by said rotation axis, and a rotation mechanism which drives said mirror bracket to rotate about said rotation axis; said mirror bracket is structured and sized, such that the mirror axis of light guider mirror points at the curved surface condenser mirror horizontally and the focus of the light guider mirror always superposes the focus of the corresponding light collecting mirror.
