Description
Technical field
The present invention relates to the solar collecting device that a kind of array type optical focuses on from axle; Be meant a kind of solar collecting device that focuses on from axle with the array type optical of one-body molded formation; The global design of this structure has clever thought; Have not shading, light weight, be prone to make, the precision advantages of higher, be particularly suitable for generating electricity or the usefulness of the high-efficiency solar collection of heat collector etc.
Background technology
Solar energy is used in the collection of energy of generating, needs preferable optically focused design, and the side is able to efficient collection and gets daylight; As commonly use the patent of solar energy system, in No. the 7109461st, United States Patent (USP) and No. 5153780 patent, exposure all be to place condenser and solar panels near the focus before a large reflective mirror; Make this large reflective mirror with sunshine reflection and concentrate in this condenser, supply solar panels to absorb energy, but this simple with sun beam reflection; Can the daylight of vast area be gathered together, but focus on high than not, generally can only have 400-500 times between; For the solar panels of costliness, the cost of paying is still high for too; In addition, this condenser is located at the large reflective mirror dead ahead and is still had the shading problem of a little, is its main shortcoming; To disclose 2009/0277498A1 number be to utilize a glass marble to be placed on the big reflecting surface mirror foci to United States Patent (USP) for another example; The rear is placed pyramid light conductor and solar panels again; Though but owing to glass marble itself does not have focussing force, and the plane angle cone focuses on than very little, so the slightly lifting of whole focusing ratio; But limited really, still have the shortcoming of shading simultaneously.The tradition thermal-arrest is many to focus on long tube with the cylindro-parabolic mirror, and interior logical heat absorption material like United States Patent (USP) 4611575,6080927 etc., though the simple long tube heat build-up after heat of optical system is prone to scatter and disappear, is all shortcomings of commonly using case.
Therefore, the design of newer solar energy equipment has large reflective mirror is made as asymmetrical arc such as United States Patent (USP) 5459996; The light that makes the sun is after being reflected by large reflective mirror, and inclined to one side side projection is absorbed by condenser or other devices again towards the place ahead; But, during the energy that applies to generate electricity, need to collect daylight in a large number and obtain sufficient energy with the permutation and combination of array because this kind belongs to the solar energy equipment of optics from shaft type; But each solar energy equipment; Be that each array element all needs individual (locking or interlocking) and the check and correction position of else large reflective mirror being assembled, ten minutes trouble on assembling, and the technology of labor intensive; Cost is very high, is the major defect of commonly using.
