Abstract

The utility model discloses a solar focusing device, which comprises a prism, wherein the cross section of which is a quadrangle; the prism is divided into a positive prism, a transitional mirror and negative prism which constitute a light gathering monomer. Both side surfaces and short-edge surfaces of the light gathering monomer are all plated with a silver coating; a half surface where a long-edge surface is adjacent to the negative prism is plated with a semi silver coating. More than one light gathering monomer is connected, is encircled, and forms a ring shape, and then, rings with unequal diameter are encircled and constitute a light gathering empty cone; more than one light gathering empty cone is encircled in the form of adjacency and constitutes a light gathering hemisphere body. The utility model has the advantages of simple structure and low cost and realizes focusing all day without following the rotation of the sun.

Description

A kind of solar energy focusing device

Technical field

The utility model relates to the device that a kind of solar energy utilizes, especially a kind of solar energy focusing device.

Background technology

A kind of Fresnel prism focalizer that is was arranged in the utilization of sun power in the past, and it is higher to the energy conversion rate that sun power utilizes, but it also has weak point, be that it is in order to focus on necessary all-weather traction sun rotation, thereby apparatus structure complexity, the cost height, a lot of users are difficult to bear economically.

Summary of the invention

The utility model aims to provide the focalizer that a kind of sun power utilizes, and it is simple in structure, and cost is low, must not follow the sun and rotate and can whole day focus on.Task of the present utility model is done in such a way that a kind of solar energy focusing device, and it includes prism; The xsect of prism is a quadrilateral, be divided into positive prism, transition mirror, negative prism three parts, this three part is formed optically focused prism monomer, two sides and the minor face face of optically focused prism monomer all are coated with silver coating, the long limit face demifacet adjacent with negative prism is coated with half silver coating that can stop most of light to see through, more than one optically focused prism monomer coupled together surround ring-type, optically focused is empty bores around forming with the unequal ring of diameter again, and adjacent the centering on of the empty awl awl of more than one a plurality of optically focused point formed the optically focused hemisphere.The utility model is simple and compact for structure, and cost is low, must not follow the sun and rotate and can whole day focus on.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.In the utility model, optically focused prism monomer is the most basic structural unit, as shown in Figure 1, its xsect is quadrilateral, it is divided into positive prism 1, transition mirror 2 and negative prism 3, and this three part fuses, and has formed optically focused prism monomer 9 jointly, two sides 4 of optically focused prism monomer 9 and minor face face 5 all be coated with can reflection ray silver coating 7, and its long limit face 6 and negative prism 3 adjacent demifacets are coated with half silver coating 8 that can stop most of light to see through.More than one optically focused prism monomer 9 coupled together surrounds ring-type, again with each ring around forming the empty awl 10 of optically focused, as shown in Figure 2.During actual fabrication, can once the empty awl 10 of optically focused be poured into an integrated entity.It is hemispherical that the empty awl 10 of more than one optically focused is assembled into outer shape, and the empty awl of each optically focused all can focus on to same point, forms focus point 11, promptly becomes a kind of solar energy focusing device of the utility model.

The utility model mainly works by the positive prism 1 on the optically focused prism monomer 9, when irradiate light is to positive prism 1, produce reflection and refraction, the refraction angle that reflects increases than reflection angle, light takes a step forward to the vertex of a cone in the empty awl 10 of optically focused, reflect so repeatedly and reflect, last light focuses at the vertex of a cone and has formed focus point 11.When irradiate light is to negative prism 3, because the most of light of the effect of half silver coating 8 is reflected away.Must some impinge upon the progressive refraction of generation on the positive prism after reflecting away, refraction back several times forms focusing, because the sun is with the empty awl 10 of parallel rays directive optically focused, and the empty awl 10 of optically focused is taper on the whole, thereby sunshine always have the part be to be radiated on the positive prism facets 1, promptly be the light that shines negative prism 3, transition mirror 2, after reflection or refraction, also have an opportunity to shine on the positive prism facets.As long as just will inevitably cause focusing so sunlight can shine on the empty awl 10 of optically focused.

After whole solar energy focusing device installs, owing to be semisphere, so the empty awl 10 of the optically focused of its top, the left and right sides, both sides, front and back all has an opportunity to be subjected to the irradiation of sunlight, always there is the empty awl 10 of part optically focused focused on by light in a certain particular moment, thereby formed and must not follow the sun and rotate the focalizer that can focus on.

Claims

1, a kind of solar energy focusing device, it includes prism; It is characterized in that: the xsect of prism is a quadrilateral, be divided into positive prism, transition mirror, negative prism three parts, this three part is formed optically focused prism monomer, two sides and the minor face face of optically focused prism monomer all are coated with silver coating, the long limit face demifacet adjacent with negative prism is coated with half silver coating that can stop most of light to see through, more than one optically focused prism monomer coupled together surround ring-type, optically focused is empty bores around forming with the unequal ring of diameter again, and adjacent the centering on of the empty awl awl of more than one a plurality of optically focused point formed the optically focused hemisphere.
