Advantageous Effects of the present utility model embodies in the following areas:
1. the utility model can provide the square hot spot of a 2m*2m, and uniform irradiation, the total irradiation of whole day can be made to bring up to more than 16MJ by 12MJ, meet the irradiation requirement of solar water heating system heat property test.Can ensure that the heat exchange situation of solar water heating system does not change simultaneously.
2., for Hefei district, 52% can be brought up to by 32% through the annual detectable number of days of statistical computation.Thus make can to detect the whole year of solar water heater about number of days is increased to twice.
3. be can Validity Test domestic solar water heater on the market, then the Validity Test area of this platform at least will more than 4 square meters, and can the use inclination angle scope of cover heating hydrophone.For make test surfaces irradiation increase and uniformity coefficient is consistent with natural light, then can not adopt curved surface condenser (as parabola dish-style optically focused and compound parabolic upper thread optically focused etc.).Must be then planar concentrating device as adopted optically focused.From whole day irradiation incident angle variation range on test surfaces, the effective focusing ratio of whole day of planar concentrating is very limited, improves focusing ratio a little, and the volume of device will have the increase of several times.For the Uniform Irradiation area making test surfaces have at least 4 ㎡, then device height and the width of simple non-tracking spot mode (mode such as composite plane and composite parabolic) may more than 15m, even more than 20m.Device is too huge, and effect is very limited, obviously can not adopt.For making test surfaces test environment identical with water heater environment for use, then water heater is immutable with the angle of surface level in testing, and water heater cannot have and obviously rocks.So, double-axis tracking mode just can not be adopted to obtain heat to the day irradiation improving water heater.Draw based on above analysis: adopt variable plane optically focused to coordinate the mode of east-west direction uniaxiality tracking, all requirements above-mentioned can be met simultaneously.Adopt variable plane optically focused can select whether use optically focused as required, and on the basis ensureing test surfaces uniform irradiation, can significantly reduce the geometric volume of device.
4. need diameter to be about the platform horizontally rotated of 3.5m and platform rotation direction can according to direction change at sunshine, tracking accuracy is at about 1 degree.The rotation of platform can self-locking, and when extraneous wind-force etc. acts on platform, platform is unlikely to be rotated.Platform needs enough rigidity, does not have and significantly teetertotters.Need a length of side to be about the plane high reverse--bias plate of 2.5m, this plate is that light ware energy within 280nm to 2.5um has almost consistent reflectivity for wavelength, and has high absorptivity for light wave in addition.This high reverse--bias plate needs fabulous flatness, the uniformity coefficient of collected light to ensure.The length of side is that the high reverse--bias plate of 2.5m will have enough intensity, can resist at least 8 grades of strong wind and not topple over and damage.When demeanour is within 4m time, this reflecting plate can not have relative to turntable plane and significantly rocks, and especially delivers direction.The length of side is that the high reverse--bias plate of 2.5m is wanted along with the change of direction of illumination, to make corresponding change of pitch angle, and pitch angle control precision needs within 2 degree.Due to reflecting plate enormous size, and excessive to windage resistance, because enough driving forces and self-lock force must be had, the position of reflecting plate just can be ensured.Due to the impact of reflecting plate and wind-force etc., platform rotate plane must have enough resistance to capsizings, maximum can resist at least 60KNm(be roughly equal to 6 tons of weights be positioned over distance fulcrum 1m place outrigger on) upsetting moment.Platform, under above acting force, all can effectively rotate.Platform velocity of rotation, except having tracking velocity, also should be regulated the speed, and is convenient to rapid adjustment contraposition.Platform has control system easily, can according to the time Automatic-searching of input and adjustment position.
