Abstract
The invention discloses a parabola type photoelectricity reflector. The photoelectricity reflector comprises two pieces of internal reflectors and two pieces of external reflectors, wherein the two pieces of the internal reflectors and the two pieces of the external reflectors are symmetrically arranged along a central shaft, and the two pieces of the internal reflectors are located at the inner sides of the two pieces of the external reflectors and form a parabola of which focal length is in a heat collecting pipe with the two pieces of the external reflectors. According to the novel solar power generation reflector, in the crosswise direction, namely, in the length direction, the reflector is composed of four pieces of reflector units and is matched with and arranged on a metal support through a bolt, the reflector can effectively resist the destroying of the natural environment, a heat collecting area is increased at the same time, and the heat collecting temperature is effectively raised. The four reflectors can be divided into two pieces of internal reflectors which are located at the center and two pieces of external reflectors which are symmetrically arranged at the outer side, the radians of these two kinds of reflectors are different, thus these two kinds of reflectors can form into a whole parabola, and the solar rays can be effectively reflected on the heat collecting pipe with focal length being 1810mm.
