Description
Technical field
The present invention relates to a kind of solar energy boundling optically focused control system, be widely used in the 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 large, 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, people are making great efforts to invent a kind of focal position always and are maintaining static, only the pursuit movement by speculum just can converge the concentrator of sunshine, proposes the design of various different thinkings, and what have develops product and successfully apply.But this class speculum can only be called " accurate fixing " in fact, or low usefulness is fixing, although this class device focus fix, 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 by focus, to adjust axle be a horizontal line by focus and face upward, so no matter how motion focus of reflecting surface always immobilizes, but shortcoming is the focal plane moves along with reflecting surface, can't form fixing focal spot on recipient.
In history, in the solar energy system of the front tracking sun, because mirror battle array and speculum have M * N control point, the series of problems such as the cost of equipment investment, gross weight of equipment amount, wind resistance, sandstorm, be the puzzlement solar thermal utilization, particularly the large-scale solar generating realizes business-like difficult point always.There is the expert to break the sun tracing method at traditional employing 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 invention proposes, all do not find a good mirror battle array focus program, large, the hot cost of electricity-generating of unit installation investment is high, photoelectric conversion rate 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.As 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 to carry out separately bidimensional to be controlled, and 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 polymerization light is reflected through central authorities at the bottom of paraboloidal mirror, uses the one side mirror reflects to the target heat collector in coaxial place again, 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 reflection for the second time of controlling M * N mirror battle array just needs M * N * 2 motor.And, for each speculum, the warp that has again, the different control of latitude deflection, this is obviously very complicated.
