Solar energy condensing electricity-generating device with summit-cutting curve condensing lens

Abstract

The invention discloses a solar energy condensing electricity-generating device with a summit-cutting curve condensing lens, which comprises a plurality of solar energy condensing electricity-generating modules and a sun-pursuing track bracket system for installing the solar energy condensing electricity-generating modules a, wherein the solar energy condensing electricity-generating modules comprise a plurality of solar energy condensing electricity-generating units which are arranged in a matrix way, the solar energy condensing electricity-generating units comprise summit-cutting curve condensing lenses and condensing cells which are arranged in the condensing areas of the summit-cutting curve condensing lenses; and each condensing cell of the solar energy condensing electricity-generating modules is connected with each other in series to outwards output electric energy. By adopting the summit-cutting curve condensing lens, the solar energy condensing electricity-generating device leads the solar energy condensing lens not only to have the optical advantage of a curve fresnel lens but also to have the machining advantage of a plane fresnel lens, which is simpler than that of the curve fresnel lens, thereby reducing the machining cost, improving the condensing effect, and greatly increasing the cost performance thereof.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a solar concentrating power generation device using a top-cut curved surface concentrating lens as the solar concentrating device. Background technique [0002] In the 1920s, physicist Fresnel proposed the theory of lens manufacturing: the imaging characteristics of a continuous optical surface mainly depend on the curvature of the surface, while the axial thickness is a secondary factor. In most cases, the increase in thickness It is caused by surface curvature or aperture requirements. Therefore, if the thickness between the two surfaces of the lens is reduced, the optical element can still focus the light on the original thick lens focus. According to the above theory, a plane Fresnel is produced. lens, see attached figure 1 . [0003] The curved Fresnel lens evolved from the plane Fresnel lens (see attached figure 2 ) mainly has two types: one is the tooth surface on...

Problems solved by technology

However, since the top of the curved Fresnel lens is a curved surface, it is difficult to release the mold and lens material, so it is difficult to realize the process, so the processing cost of the curved Fresnel lens is much higher than that of the flat Fresnel lens
