Embodiment

Below in conjunction with accompanying drawing, the present invention is further elaborated.

Shown in figure 1, one embodiment of the present of invention are the reflective heat build-up of a kind of solar generator and heat reservoir, described system comprises energy gathering cap 1, the cumulative center position of described energy gathering cap 1 is provided with reflecting means 2, the position that described energy gathering cap 1 coincides with the normal of reflecting means 2 is provided with energy boot media 3, described energy boot media 3 is for the outside of the solar energy to guide to energy gathering cap 1 that will come from reflecting means 2, and energy boot media 3 is divided into two-way in the outside of energy gathering cap 1, wherein an end, road 31 close to or access solar generator 4 energy input end, heat-storing device is accessed on another road 32.

In the present embodiment, consider that the solar energy of collection energy loss can occur in the process of conduction, therefore reflecting means is adopted to reflect through energy gathering cap 1 and the sunlight converged, again converge and reflex in energy boot media 3, due to sunlight is passed through twice convergence, therefore the temperature after it injects energy boot media 3 is greatly improved, and then conducted by energy boot media 3 again, even if there is aforesaid energy loss, also its energy conducted can be made to play due effect, be namely used directly and store rear indirect utilization.

According to another embodiment of the present invention, can directly adopt heat storage box (not shown) of the prior art as above-mentioned heat-storing device, and heat storage box is also accessed by heat-transfer tube 7 or end close to the energy input end of solar generator, when energy gathering cap 1 directly cannot gather solar energy, by the energy input end transmission heat of heat-transfer tube 7 to solar generator 4, thus ensure that it continues to run.

As shown in Figure 1, in another embodiment of the invention, with reference to optical principle of the prior art, it can be the concaver of spherically shape by energy gathering cap 1, to form the reflecting focal of sunlight, the pole 8 that above-mentioned reflecting means 2 is extended by energy gathering cap 1 edge is fixed on the cumulative central position of energy gathering cap 1, can make like this to keep at a distance between itself and energy gathering cap 1, with the angle facilitating adjustment second time to converge back reflection light, twice convergence of above-mentioned sunlight is reflected and more easily realizes; The quantity being placed in aforementioned pole 8 can be arranged arbitrarily, is as the criterion reflecting means 2 can be fixed on specified position and keep stable.

Shown in Fig. 1, in the embodiment that the present invention is more preferably for technical solution problem, inventor considers that sunlight incident angle is all the time all not identical, need the angle of constantly adjustment energy gathering cap that its concave surface just can be made to remain at best daylighting position, therefore go out as shown in Figure 2, need on the one hand in above-mentioned reflecting means 2 to arrange the optical concentration mirror 21 being used for second time reflecting focal sunlight, need to arrange sunlight direction follower head 22 on the other hand, optical concentration mirror 21 is placed in the below of sunlight direction follower head 22, the effect of this sunlight direction follower head 22 is by Microprocessor S3C44B0X, the real time position of energy gathering cap 1 is adjusted by three-axis parallel 5, inject direction with sunlight to be consistent, its method controlled is as follows:

Steps A, sunlight direction follower head, with the angle of sunlight incidence, export corresponding optical signal to photoelectric conversion module, by photoelectric conversion module, optical signal are converted to address signal, and export microprocessor or temporary address signal to and call for microprocessor;

Step B, microprocessor call pre-configured orientation displacement data according to address signal from the first data storage device, and from the second data storage device, obtain the instant displacement data following the tracks of displacement actuator, obtain the difference displacement amount of the two through computing, then export tracking displacement actuator to after choosing chip port by code translator; In this step, for ensureing that above-mentioned difference displacement amount exports temporal consistency when following the tracks of displacement actuator to, and there is verifying function, microprocessor before calling pre-configured orientation displacement data from the first data storage device, preferably first send to tracking displacement actuator the chip port that Received signal strength opens its data receiver, and then export difference displacement amount to tracking displacement actuator after choosing chip port by code translator.

Step C, tracking displacement actuator drive three-axis parallel 5 that energy gathering cap 1 is rotated towards set direction according to this difference displacement amount, and rotational displacement is equal with this difference displacement amount.

Further, above-mentioned three-axis parallel 5, at least two axles in three-axis parallel 5 are provided with actuating motor, namely above-mentioned tracking displacement actuator, for choosing according to code translator and the motion of the difference displacement amount inputted drive three-axis parallel; Microprocessor gathers the displacement data of three-axis parallel by displacement transducer and transfers to the second data storage device.According to above-mentioned structure, above-mentioned solar generator 4 can be arranged on the below of energy gathering cap 1, and directly be placed on installation table top, the load of energy gathering cap 1 can be reduced like this, thus the requirement reduced to three-axis parallel 5 power when it rotates, adopt low power motor to drive.

Shown in figure 3, according to another embodiment of the present invention, for making above-mentioned minimizing energy loss of trying one's best in conductive process through the sunlight of twice reflecting focal, can directly adopt optical fiber catheter of the prior art as above-mentioned energy boot media 3, namely as described above, after outside the bottom that optical fiber catheter extends to energy gathering cap 1, bifurcated is two-way, and part realizes two-way optical fiber catheter all has identical or approximate solar energy to conduct, the bifurcation site of the also fine catheter interior of light requirement sets up optical prism 6, namely acting as in the two-way reflected respectively by the solar energy coming from reflecting means 2 as optical fiber catheter bifurcated of this optical prism 6 carries out heat transfer, its principle is that namely optical prism 6 self has reflective functions, again can by light penetration, therefore when it is arranged on the crotch of optical fiber catheter with the position being similar to miter angle, sunlight after twice convergence arrives rear portion and is reflected by optical prism 6, a wherein road along optical fiber catheter arrives heat-storing device, another part directly injects the energy input end of solar generator 4 through optical prism 6, namely when sunlight abundance, carry out solar generator 4 thermal transition mechanical work and heat storage box heat accumulation simultaneously.

According to another embodiment of the present invention, as mentioned here above, above-mentioned solar generator 4 can directly adopt stirling generator of the prior art, for converting solar energy into the running of mechanical energy drive electrical generators.And stirling generator is a kind of can be the closed loop regenerative engine of the energy with pluralities of fuel; Or being referred to as heat engine, it is the another class reciprocating power machinery except steamer and internal-combustion engine; It both can use as prime mover, also can use as refrigerator, heat pump or pressure generator.
