Specific implementation mode
The present invention is further explained in the light of specific embodiments.
A kind of more bell-type free of sun tracking energy beam condensing units of single column, including hollow metal trunk 1, photomask 2, reflecting piece 3,
Window 4, fixing bolt 5, spring 6 and pedestal 7 are provided with several photomasks 2, the collection on the metal trunk 1 from top to bottom
Light shield 2 is uniformly fixed on metal trunk 1 successively by fixing bolt 5;Positioned at the gold of 2 center sunny slope of photomask
Owner dry 1 is equipped with a window 4, and there are an inclination reflecting piece 3, vertical height of 4 size of window with reflecting piece 3 in 4 inside of the window
Degree is consistent, and window 4 is covered by transparent glass;The reflecting piece 3 is male type reflective mirror, 2 curvature one of curvature and photomask
It causes;The angle of inclination of reflecting piece 3 is sequentially increased from upper to small in each photomask 2.
It is equipped with the aperture that a pair of of line crosses axis every a distance on the metal trunk 1, the spacing distance is bigger
In the diameter of photomask 2, the fixing bolt 5 that a pair fixes photomask 2 is pierced by by aperture respectively inside metal trunk 1, and
Including the major part of fixing bolt 5, and it is connected by spring 6 between symmetrical two fixing bolts 5.Under normal circumstances, Gu
Determining bolt 5 can be acted on due to spring 6, and be projected into 1 outside of metal trunk, if firmly squeezed from outside, fixing bolt 5 can be received
It is reduced in metal trunk 1.
The photomask 2 is spherical structure, and material is glass or acrylic transparent material, and crossing the centre of sphere has size etc.
