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.
In history; In the solar energy system of the front tracking sun; Because mirror battle array and speculum have M * N control point; A series of problems such as the cost that equipment drops into, gross weight of equipment amount, wind resistance, sandstorm are the puzzlement solar thermal utilizations always, and particularly the large-scale solar generating realizes business-like difficult point.There is the expert to break the sun tracing method at Traditional use azimuth-elevation angle; Proposed to adopt the tracking formula at the spin-elevation angle; The system of computerizeing control has realized that M * N control module is reduced to M+N control module; Be M * N=M+N, before this, do not find that all a good mirror battle array focuses on scheme; Big, the hot cost of electricity-generating of unit installation investment is high, photoelectric conversion rate is low and none surpasses 30% so that produce, and is difficult to the solar energy thermal-power-generating factory of butterfly that commercialization promotes, slot type, tower cumulative.Like the tower technology that extensively is employed in such technology, numerous heliostats is set up around central tower, and floor space is huge; Each heliostat need carry out bidimensional control separately, and the control system is extremely complicated; In order to reduce the cosine effect of numerous heliostats, central tower must be built enough highly, invests excessive.
China once had in parabolic focus installs a speculum, and central authorities at the bottom of the paraboloidal mirror are passed in the polymerization light reflection, uses the one side mirror reflects to the target heat collector again in coaxial place, one Chinese patent application numbers 201010153222.9.This method, it is easy controlling a mirror, still, controls a mirror and just needs 2 motors, so, the speculum of the reflection second time of M * N mirror battle array of control just needs M * N * 2 motor.And, to each speculum, the control that the warp that has again, latitude deflection have nothing in common with each other, this obviously is very complicated.
