By parity of reasoning, the second annular belt, the third annular belt, the fourth annular belt, the fifth annular belt and the sixth annular belt have the same shielding condition. And finally, fastening the positioning nut I and the positioning nut II to enable the annular plate to be rigidly connected with the adjusting plate I. Therefore, the effect of changing the quantity of light rays passing through the light through holes in a mode of rotating the adjusting plate II within the range of 0-30 degrees is achieved, and continuous and adjustable irradiation is achieved.
When the light shielding plate structure is used, the pitch angle of the light shielding plate structure relative to a rear light propagation path of a light condensing system is adjusted by changing the tightness of the pull screw I, the top screw I, the pull screw II, the top screw II, the pull screw III and the top screw III and utilizing a three-top three-pull principle, so that the light shielding plate structure has a certain angle relative to the light propagation path. At this moment, except the shading effect that the relative rotation of light screen with the regulating plate leads to logical unthreaded hole dislocation to bring, every logical unthreaded hole of light screen structure can bring extra shading effect because the every single move angle, and because every logical unthreaded hole for the every single move angle of light propagation path has the nuance, the extra shading effect that every logical unthreaded hole of light screen structure brought also has the nuance, and the logical unthreaded hole that is close condensing system is little to the extra effect of sheltering from of light, and the logical unthreaded hole of keeping away from condensing system is big to the extra effect of sheltering from of light, utilizes this kind of nuance to compensate irradiation surface irradiation and distributes inhomogeneous problem.

Fig. 7 is a schematic structural diagram of an auxiliary rotating structure of a shading device continuously adjustable for solar simulator irradiation according to an embodiment of the present invention. As shown in fig. 7, in the auxiliary rotating structure, the radial plate 31 is tightly attached to the adjusting plate i 12 from back to front through the positioning screw i 3411, the positioning screw ii 3421, the positioning gasket i 3412, the positioning gasket ii 3422, the positioning through hole iii 312, the positioning through hole iv 313, the positioning nut i 3413 and the positioning nut ii 3423 on the radial plate 31, and when the tightness of the positioning screw i 3411, the positioning screw ii 3421, the positioning nut i 3413 and the positioning nut ii 3423 is adjusted, the circumferential plate 31 and the adjusting plate i 12 achieve two states of rigid connection and relative displacement along the positioning through hole ii 125.

When in use, the substrate II21 is fixed on the adjusting plate I12 from front to back through the fixing screws I231, the fixing screws II 232 and the fixing screws III 233; then, the adjusting plate II22 is placed into the tapered hole 126 of the adjusting plate I12 from back to front, and meanwhile, the circular connecting shaft 2260 and the base plate II21 form loose interference fit; secondly, the annular plate 31 and the radial plate 32 are respectively in rigid connection with an adjusting plate I12 and an adjusting plate II22 through a positioning screw I3411, a positioning gasket I3412, a positioning nut I3413, a positioning screw II 3421, a positioning gasket II 3422, a positioning nut II 3423, a fixing screw IV 331 and a fixing nut 332; finally, the adjusting plate I12, a shading plate structure fixedly connected to the adjusting plate I12 and an auxiliary rotating structure are fixed on the base plate I11 through a pull screw I1311, a top screw I1312, a pull screw II 1321, a top screw II 1322, a pull screw III 1331 and a top screw III 1332, and the pitch angle of the shading plate structure relative to the rear light propagation path of the condensing system is adjusted by utilizing a three-top three-pull principle, so that light emitted from the condensing system vertically passes through each light through hole. At this time, the state is an initial state, and all the light-transmitting holes on the substrate II21 and the adjusting plate II22 are overlapped. If the positioning nut I3413 and the positioning nut II 3423 are loosened, the auxiliary rotating mechanism is enabled to cling to the surface of the adjusting plate I12 along the positioning through hole 125 to perform circular motion with the center of the adjusting plate I12 as the center of circle, meanwhile, the pentagonal connecting shaft 322 drives the adjusting plate II22 to closely attach to the surface of the substrate II21 for rotary displacement with the circular connecting shaft 2260 as the center of circle, therefore, the overlapping condition of the light through holes on the first ring belt of the adjusting plate II22 is changed, the light-tight part between the light through hole XIII22611 and the light through hole XIV22612 can shield a part of the light through hole II 21612 on the base plate II21, the light-tight part between the light through hole XIV22612 and the light through hole XV22613 can shield a part of the light through hole III 21613, the light-tight part between the light through hole XV22613 and the light through hole XVI22614 can shield a part of the light through hole IV 21614, the light-tight part between the light through hole XVI22614 and the light through hole XVII22615 can shield a part of the light through hole V226 21615, and the light-tight part between the light through hole XVII22615 and the light through hole XVIII22616 can shield a part of the light through hole VI 21616.

Finally, the positioning nut I3413 and the positioning nut II 3423 are fastened, so that the annular plate 31 is rigidly connected with the adjusting plate I12. Therefore, the effect of changing the quantity of light rays passing through the light through holes is achieved by rotating the adjusting plate II22 within the range of 0-30 degrees, and the irradiation is continuously adjustable.
In use, the pitch angle of the light shielding plate structure 2 relative to the light propagation path behind the light condensing system 5 is adjusted by changing the tightness of the pull screw i 1311, the top screw i 1312, the pull screw ii 1321, the top screw ii 1322, the pull screw iii 1331 and the top screw iii 1332, and the three-top three-pull principle is utilized, so that the light shielding plate structure 2 has a certain angle relative to the light propagation path. At this moment, except the shading effect that the relative rotation of base plate II21 and regulating plate II22 leads to logical unthreaded hole dislocation to bring, every logical unthreaded hole of visor structure 2 can bring extra shading effect because the every single move angle, and because every logical unthreaded hole for the every single move angle of light propagation path has the nuance, the extra shading effect that every logical unthreaded hole of visor structure 2 brought also has the nuance, and it is little to be close the extra effect of sheltering from of the logical unthreaded hole of condensing system 5 to light, and the logical unthreaded hole of keeping away from condensing system 5 is big to the extra effect of sheltering from of light, utilizes this kind of nuance to compensate the inhomogeneous problem of irradiation face irradiation distribution.
