Embodiment

Further explanation in detail in conjunction with the accompanying drawings;

Shown in Fig. 1～3, being contained on the support 1 of integral type planar shaped Fresnel Lenses 2 detachable property, support 1 is regulated rotating shaft 4 automatically with the angle of pitch in the solar two-dimension real-time automatic tracking device 3 and is solidly installed, it is adjustable and with the function transaxle 5 of spacing rotating mechanism that the position also is housed on the support 1, heat collection function body 6 is housed on this axle, heat collection function body 6 must be positioned near the focus position of Fresnel Lenses 2, heat collection function body 6 is plate shaped, it simultaneously is a photovoltaic battery panel 7, photovoltaic battery panel 7 can be converted to electric energy with sunlight and also export near described focus position, store, its another side is the completely reflecting mirror 8 with certain focal length, completely reflecting mirror 8 can reflex to heated object 9 with sunlight near described focus position, heated object 9 is contained on the carrier 10, carrier 10 is contained on the support 1, and the heated object 9 that is equipped with on the carrier 10 must be able to be in completely reflecting mirror 8 near the opticpath of the sunlight that reflects the described focus position; 7 generatings of solar light irradiation photovoltaic battery panel, or irradiation completely reflecting mirror 8 heating that is reflected, can change mutually by spacing rotating mechanism between two functions, photovoltaic battery panel 7 near the focus position of Fresnel Lenses with after directed spacing the turning an angle of function transaxle 5, sunlight could be reflexed on the heated object 9 by completely reflecting mirror 8, and it is heated.

As shown in Figure 1, 2, the structure of the spacing rotating mechanism of function transaxle 5 is, the two ends of function transaxle 5 are contained on the support 1 by axle sleeve 11, the connecting lever 12 of tight handle 13 with lock is housed on one end of function transaxle 5, other has the position-arresting disk 15 of band circular arc slideway 14 to be packed on the frame 1, circular arc slideway 14 is supporting with the directed spacing rotation of set lever 13 and function transaxle 5, the free end with connecting lever 12 that the end of thread of set lever 13 can pass, also can slide in circular arc slideway 14 is screwed onto, simultaneously can clamp position-arresting disk 15, make function transaxle 5 location; Unclamp and rotation lock handle 13, thereby rotate connecting lever 12 and promptly drive 5 rotations of function transaxle, photovoltaic battery panel 7 is from spending the directed spacing α that turns an angle with function transaxle 5 since 0 near the focus position of Fresnel Lenses, when angle [alpha] is spent greater than 90, sunlight just can be radiated on the completely reflecting mirror 8 when spending less than 180, and be reflected on the heated object 9 that is contained on the carrier 10, to heated object 9 heating;

" orientation " in described " the 5 directed spacing rotations of function transaxle " is orientation with the orientation that the position was determined that is contained in the heated object 9 on the carrier 10, is the direction of generating, the function transaxle 5 spacing rotations when changing mutually of heating two functions.

Shown in Fig. 1,3, the structure that is contained on the frame 1 of integral type planar shaped Fresnel Lenses 2 detachable property is, has the support bar 19 that supports Fresnel Lenses 2 on the support 1, its top has axial internal thread hole 16, bolt 17 pass on the Fresnel Lenses 2 install connecting hole 18 after be tightened in the internal thread hole 16, Fresnel Lenses 2 is packed on the support bar 19; Unload bolt 17 and promptly can easily unload Fresnel Lenses 2.

Because photovoltaic battery panel 7 is subjected to solar light irradiation near the focus position of Fresnel Lenses 2, temperature is higher, the high temperature resistant type photovoltaic battery panel of selecting for use GaAs or gallium arsenide-phosphide to make.

The described angle of pitch is meant the angle that optical axis and ground level were of integral type planar shaped Fresnel Lenses to be called elevation angle in the astronomy.

Completely reflecting mirror 8 is plating deielectric-coating or a metal film on the metal substrate.
