Description
Technical field
The present invention relates to a kind of optical test path system, especially a kind of indoor light path test system of solar energy reflection formula condenser belongs to technical field of solar utilization technique.
Background technology
The energy is the important substance basis that the national economic development and living standards of the people improve, along with growing continuously and fast of economy, the environmental problem that the resource-constrained of fossil energy and development and use bring more and more becomes the restraining factors of the sustainable development of economic and society.The development and use of accelerating regenerative resource are important channel and the measures that solve the energy and environmental problem.Sun power is cleanliness without any pollution and the never exhausted energy, and solar electrical energy generation is one of regenerative resource with fastest developing speed, also is the emphasis that various countries competitively develop.
Traditional detection method for solar concentrating system has two kinds, and a kind of is the asterism observation procedure, and another kind is the resolving power test target observational technique.These two kinds of methods are fairly simple, mainly are fit to visual observation, and empirical requirement is very strong, the focal spot size, differ picture element etc. and are difficult to accurately measure.Device for detection of focal spot can adopt the visual measurement mechanism of traditional parallel light tube, but the inconvenience of use, human eye is tired easily, and measurement result also might vary with each individual.
But owing to need highly to rely on weather conditions in the solar concentrating system development process, if fine few, the time that direct light occurs is not long, will cause the time of test condenser light path very limited, thereby greatly prolongs the R﹠D cycle of solar concentrating system.Moreover there is the inconvenience part in outdoor light modulation, needs the platform of the complicated tracking sun, and under the aerial work condition light path is revised also comparatively difficulty.
Therefore the present invention proposes a kind of indoor light path test system, can test easily and adjust on ground the light path of solar concentrating system, and do not rely on outdoor sunlight conditions, whole day all can test and adjust in 24 hours, can greatly shorten the R﹠D cycle thus.
The product that the present invention also can be used for the large-scale production condenser detects.
The present invention also can be used for the condenser group is adjusted in indoor basic installation, and then going up only needs fine setting to satisfy on the outdoor support.More can be directly substantially the mirror group both sides of installation in position temporary track is set, the direction along ng a path mobile device.Even the work progress of large solar optically focused engineering also can be carried out with night overcast and rainy, significantly shorten the construction period.
The present invention also can be used for the energy flux density test of optically focused focal spot inside and adjusts.The homogeneity of focal spot energy flux density is extremely important performance assessment criteria of concentration photovoltaic system, and is domestic owing to there is no effective energy flux density method of testing, so this system fills the domestic gaps, and can greatly promote development and the scale of concentration photovoltaic system.
