Embodiment
With reference to specific embodiment, the invention will be further described.
A kind of many bell-type free of sun tracking energy beam condensing units of single column, including hollow metal trunk 1, photomask 2, reflecting piece 3,
Some photomasks 2, the collection are provided with window 4, fixing bolt 5, spring 6 and base 7, 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 the center sunny slope of photomask 2
Owner dry 1 is provided with a window 4, and there are an inclination reflecting piece 3, vertical height of the size of window 4 with reflecting piece 3 in the inner side of window 4
Degree is consistent, and window 4 is covered by clear glass;The reflecting piece 3 is male type reflective mirror, its curvature and the curvature one of photomask 2
Cause;The angle of inclination of reflecting piece 3 increases successively from upper to small in each photomask 2.
Cross the aperture of axis provided with a pair of lines every a segment distance on the metal trunk 1, the spacing distance is bigger
In the diameter of photomask 2, the fixing bolt 5 of a pair of fixation photomasks 2 is passed by aperture respectively inside metal trunk 1, and
Including the major part of fixing bolt 5, and it is connected between symmetrical two fixing bolts 5 by spring 6.Under normal circumstances, Gu
Determining bolt 5 can be because spring 6 be acted on, and is projected into the outside of metal trunk 1, if firmly from outside extruding, fixing bolt 5 can be received
It is reduced in metal trunk 1.
The photomask 2 is spherical structure, and its material is glass or acrylic transparent material, and it, which crosses the centre of sphere, size etc.
The cylindrical void of the diameter of metal trunk 1 is same as, is easy to photomask 2 to be punctured on metal trunk 1.
