Specific embodiment
Thermal shield and use below in conjunction with the drawings and specific embodiments to a kind of correcting camera 6 proposed by the present invention
The camera calibration device of the thermal shield is described in further detail.According to following explanation and claims, of the invention is excellent
Point and feature will become apparent from.
Embodiment 1
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of 6 thermal shield of correcting camera, it is anti-that correcting camera 6 is set to 6 heat of correcting camera
The inside of shield, comprising: Stainless Steel Shell 2, heat-preservation cotton (not marked in figure), windowpane 7, insulating brick (not marked in figure) and
Barn door 3；Stainless Steel Shell 2 is sandwich structure, and the inner surface and outside table of Stainless Steel Shell 2 are coated with reflection paint, stainless steel
The top surface of shell 2, bottom center part and the back side are engraved structure, and before Stainless Steel Shell 2 and the angle of horizontal plane is
15 degree~45 degree, correcting camera 6 can be made to observe the heliostat 1 of different distance；Heat-preservation cotton is embedded in Stainless Steel Shell 2
At sandwich, windowpane 7 is set at the front openings of Stainless Steel Shell 2, and windowpane 7 is not less than the reflectivity of visible light
95%, windowpane 7 is not less than 70% to the reflectivity of infrared light, and the part sunray that multiple heliostats 1 reflect penetrates glass
Window 7 exposes to the inside of Stainless Steel Shell 2, and insulating brick is set to the junction of windowpane 7 Yu Stainless Steel Shell 2, and barn door 3 is set
It is placed in the inner face edge of windowpane 7.
Stainless Steel Shell 2 in the present embodiment uses sandwich structure, is embedded with heat-preservation cotton at the sandwich of Stainless Steel Shell 2,
In addition, the inner surface of Stainless Steel Shell 2 and outside table are coated with reflection paint, the top surface of Stainless Steel Shell 2, bottom center part with
And the back side is engraved structure, before Stainless Steel Shell 2 and the angle of horizontal plane is 15 degree~45 degree, before Stainless Steel Shell 2
The opening in face is equipped with windowpane 7, and windowpane 7 is not less than 95% to the reflectivity of visible light, reflectivity of the windowpane 7 to infrared light
Not less than 70%, the part sunray that multiple heliostats 1 reflect exposes to the inside of Stainless Steel Shell 2, glass through windowpane 7
The junction of glass window 7 and Stainless Steel Shell 2 is additionally provided with insulating brick and the inner face edge of windowpane 7 is equipped with barn door 3.The heat
Shield can reduce the temperature of correcting camera 6, and correcting camera 6 is protected not to be damaged.
In the present embodiment, due to 7 non-refractory of windowpane, and the temperature of Stainless Steel Shell 2 is higher when working, if directly
It is contacted with windowpane 7, then windowpane 7 can be made to be more than operating temperature and fail, windowpane 7 also will further result in school after failing
Positive camera 6 is destroyed.Therefore, it is damaged to protect windowpane 7 from heat that Stainless Steel Shell 2 passes over, at 7 liang of windowpane
It is provided with insulating brick between side and Stainless Steel Shell 2, to completely cut off the conduction to windowpane 7 of heat.
In the present embodiment, due to insulating brick non-refractory, 1 reflected light of heliostat need to be avoided directly to impinge upon on insulating brick,
Therefore 7 both sides of windowpane are provided with barn door 3, the Design of length of barn door 3 will not according to the solar radiation that windowpane 7 reflects
Criterion on insulating brick is fallen on, barn door 3 should meet hot spoke of the windowpane 7 by high temperature barn door 3 with the distance design of windowpane 7
It penetrates, still the use of temperature is criterion no more than the theory of windowpane 7.
In general, solar radiation energy is made of 50% visible light and 50% infrared light, reflection is generally sold on the market
Glass often only reflects visible or infrared light.Under 100kW peak value throwing power, even if monolithic infrared external reflection glass reflects
100% infrared energy, yet surplus 50kW visible light energy enters in thermal shield, and such energy-flux density quickly i.e. can be right
Correcting camera 6 damages.And the scheme for using a piece of infrared external reflection glass and a piece of visible reflectance glass to be superimposed, although energy
Make to be down to desirable level into shield internal energy, but the gap between two panels reflecting glass will generate strongly under strong light environment
Hui Ying, unacceptable influence is generated on the imaging of correcting camera 6, reduces the accuracy of correction.
The inclination of windowpane 7 in the present embodiment is not less than 95% to the reflectivity of visible light, not to the reflectivity of infrared light
Less than 70% so that into the energy inside thermal shield be only the 17.5% of gross energy.Under 100kW peak value throwing power,
After the reflection of windowpane 7, actually enters the energy inside thermal shield and only have 17.5kW, within the acceptable range, keep away simultaneously
Exempt to return shadow problem strongly caused by multi-disc rear reflector gap.
