Description
Technical field
The utility model relates to a kind of solar energy boundling optically focused and controls system, is widely used in fields such as solar energy thermal-power-generating, solar airconditioning, heating, hot water.
Background technology
At solar energy heat utilization field, rotational paraboloid mirror is to converge sunshine the most effectively to install always, but its focus is along with speculum moves together.This just makes the size of recipient and quality all be restricted, and size is big, and design, manufacturing, installation accuracy are had any problem, if slot type, towerly also can block speculum, quality has weighed and can increase the load of support bar; Simultaneously, the thermal-arrest recipient is kept in motion and also is unfavorable for the derivation of energy and the design of insulation.In order to address this problem; It is fixed that people are making great efforts a kind of focal position of invention always; Only just can converge the concentrator of sunshine through the pursuit movement of speculum, propose the design of various different thinkings, what have develops product and successfully applies.But this type speculum can only be called " accurate fixing " in fact; Or low usefulness is fixing, though this type device focus is fixed the plane at focal spot place; Be that rich focussing movement is but enclosed in the focal plane, so their performance is not as real fix-focus type condenser mirror.Modal is exactly that a kind of focus of enclosing is made the orientation---the solar cooker that follow the tracks of at the elevation angle; Its orientation adjustment axle is a vertical line through focus; And face upward the adjustment axle is a horizontal line through focus; So no matter how motion focus of reflecting surface always immobilizes, but being the focal plane, shortcoming moves along with reflecting surface, can't on recipient, form fixing focal spot.
