Utility model content
The technical problem to be solved by the utility model is in view of the deficiency of the prior art, provide a kind of sun
Energy condenser, structure is simple, it is convenient to realize, using dual paraboloid structure, carries out optically focused by the paraboloid of no color differnece, relatively
There is no color differnece in traditional condenser, be simple to manufacture, the high advantage of light gathering efficiency, suitable for the various fields for needing to collect solar energy
It closes, solar energy utilization ratio can be greatly improved.
In order to solve the above technical problems, the technical solution that the utility model is taken is as follows:
A kind of solar concentrator, including concentration module and sun tracker are constructed, the concentration module includes first
Paraboloid, the second paraboloid and concave spherical surface, first paraboloid is identical as the second paraboloid curved surface face type, second parabolic
Face can no color differnece reflected sunlight to the second paraboloidal focus, the centre of sphere of the concave spherical surface and the second paraboloidal focal position
It is overlapped, the sun tracker is mounted below concentration module, is welded with concentration module, and the sun tracker has south
Two north, thing tracking directions, can real-time tracking solar azimuth, make the concentration module face sun, the solar concentrator peace
Mounted in roof and by positive metope.
Compared to the prior art the utility model has the advantage that
Firstly, the solar concentrator uses dual paraboloid structure, optically focused is carried out by the paraboloid of no color differnece, relative to
Traditional condenser has no color differnece, is simple to manufacture, the high advantage of light gathering efficiency, suitable for the various fields for needing to collect solar energy
It closes, solar energy utilization ratio can be greatly improved.
Secondly, the solar concentrator includes sun tracker, there is two north and south, thing tracking directions, it can be real-time

Specific embodiment
In order to which technical solutions of the utility model and beneficial effect are more clearly understood, with reference to the accompanying drawings and embodiments,
The present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used for explaining this reality
With novel, it is not used to limit the utility model.
As Figure 1-Figure 2, a kind of solar concentrator, including concentration module 1 and sun tracker 2, the optically focused
Module 1 includes the first paraboloid 11, the second paraboloid 12 and concave spherical surface 13, and first paraboloid 11 and the second paraboloid 12 are bent
Face face type is identical, second paraboloid 12 can focus of the no color differnece reflected sunlight to the second paraboloid 12, the concave spherical surface
13 centre of sphere is overlapped with the focal position of the second paraboloid 12, and the sun tracker 2 is mounted on 1 lower section of concentration module, with
Concentration module 1 weld, the sun tracker 2 have two north and south, thing tracking directions, can real-time tracking solar azimuth,
Make the 1 face sun of concentration module, the solar concentrator is mounted on roof and by positive metope.
In the present embodiment, the concentration module 1 of single solar concentrator might not meet photovoltaic power generation light harvesting area
It is required that therefore array can be carried out to meet photovoltaic power generation light harvesting area requirements to concentration module 1 according to practical usable condition.
The specific design method of the present embodiment includes the following steps:
Step S1 establishes the parabolic equation of concentration module 1 first paraboloid 11 and the second paraboloid 12, rotary parabolic
Line constructs the first paraboloid 11 and the second paraboloid 12, carries out boolean to the entity of the first paraboloid 11 and the second paraboloid 12
The parabolic equation of intersection operation, the first paraboloid 11 and the second paraboloid 12 is defined by the formula:
Y=az2
Wherein a is parabolic coefficient, and the distance between the first paraboloid 11 and the second paraboloid 12 are 1/2a.
Step S2, determines the height bound of concentration module 1, intercepts the height h of concentration module 1, height bound by
Following formula determines:
Wherein hmaxFor 1 maximum height of concentration module, hminFor 1 minimum constructive height of concentration module, n1For the refraction of concentration module 1
