NOVELTY - The system has a non-linear solar energy lens bracket arranged on a tracking bracket of a solar energy tracking device, and rotating shafts arranged on solar energy linear focusing optical lenses. The rotating shafts of every group of optical lenses are arranged on the solar energy lens bracket. A power driving device is used for driving a power transmission mechanism to make the optical lenses to move so as to realize a condition that focal lines of every group of optical lenses is held in a columnar area where a solar energy utilizing device is located.    USE - Solar energy linear multi-mirror zooming single-direction tracking and utilizing system. Uses include but are not limited to photovoltaic power generation field, thermal power generation field, high temperature steam generation field, heating application and cooking application.    ADVANTAGE - The solar energy utilizing device is arranged in an interval of columns and on ground or building and is not moved when the solar energy mirror moves to track focal length by zooming so as to realize multiple utilizations of solar energy for focusing and tracking. The system provides array structure, which is suitable for the systems with different scales.    DETAILED DESCRIPTION - The solar energy utilizing device is provided with secondary reflectors. The solar energy lens bracket is formed in shape of parabola, arc, round, polygonal bracket or compound parabola. The solar energy utilizing device is selected from a group consisting of a solar energy device for directly converting solar energy into electric energy, a hot tube for converting solar energy into heat energy, a heat energy fluid heat exchanger for converting solar energy into fluid, a solar energy stove, a device for converting the solar energy into heat energy and generating power via the heat energy and a device for drying and cracking solar energy. The optical lenses and the secondary reflectors are selected from a group consisting of linear compound paraboloid reflectors, linear Fresnel lenses or reflectors, linear concave and convex lenses, linear paraboloid reflectors and glass, metal or non-metal plane reflectors.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a solar energy linear multi-mirror zooming single-direction tracking and utilizing system.
