Problems solved by technology

However, it is undeniable that the rotation of the mirrors in the system may block sunlight from each other during tracking, so the flat mirrors in the light-concentrating array are often arranged sparsely, which makes the utilization of sunlight low. correspondingly requires very large

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, which does not constitute any limitation to the present invention.

[0034] When sunlight 1 is incident in the initial direction, by figure 1 As shown, the sunlight is reflected by the V-shaped mirror 2 to two focusing targets 10 and 20. As time goes by, the incident direction of sunlight 1 changes, such as figure 2 As shown, the V-shaped mirror 2 also rotates at a corresponding angle, and the sunlight is still reflected by the V-shaped mirror 2 to the two focusing targets 10 and 20 . Certainly the two mirrors of V-shaped mirror 2 can not be limited to plane mirror, can be designed into certain radian, as image 3 As shown, the arc-shaped V-shaped mirror 4 can also have a certain auxiliary light-gathering effect while reflecting. Figure 4 It is shown that several V-shaped mirrors form an array 5, and each V-shaped mirror reflects ...

Abstract

The invention discloses a solar reflecting concentration array, which comprises a series of V-shaped rotary mirrors, a plurality of rotating mechanisms, a control chip, a concentration target and other components, wherein the V-shaped mirror array operates around an axis according to a specific rule through the rotating mechanisms; and due to different array arrangement modes, the included angles of the V-shaped mirrors are different, but the rotating speeds of the mirrors are consistent. The array can keep the optimal solar incidence angle and refraction angle, so that the concentrated sunlight is always aligned with the concentration target. Due to the design of the V-shaped mirrors, various mirrors do not block light rays, the sunlight utilization rate is high, and the V-shaped mirror array is small in occupied space, suitable for different sites, simple in structure and easy to install; and compared with compound parabolic concentration, the solar reflecting concentration array is lower in cost.

Description

technical field [0001] The invention relates to a concentrating array, in particular to a solar reflective concentrating array composed of a series of mirrors, which belongs to the technical field of solar concentrating. Background technique [0002] Solar concentrating refers to the use of a special mirror to gather light to generate high-intensity light energy by using the reasonable arrangement of light refraction, reflection and direct radiation, which is often accompanied by high temperature on the concentrating target. The form of energy is then converted, for example to generate electricity, by means of optoelectronic semiconductors or heat engines. At present, it is mostly used to generate high temperature by concentrating light and then applied to various occasions, such as to increase the temperature of water, and advanced applications such as industrially use the high temperature generated by concentrating light to melt various objects. [0003] At present, compo...
