Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
With reference to 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, comprise energy gathering cap 1 in the described system, the cumulative center position of described energy gathering cap 1 is equipped with reflecting means 2, the position that coincides with the normal of reflecting means 2 on the described energy gathering cap 1 is provided with energy boot media 3, described energy boot media 3 is used for will coming from the solar energy to guide of reflecting means 2 to the outside of energy gathering cap 1, and energy boot media 3 is divided into two-way in the outside of energy gathering cap 1, wherein one tunnel 31 end approaches or inserts the energy input end of solar generator 4, and heat-storing device is inserted on another road 32.
In the present embodiment, energy loss can take place in the solar energy of considering collection in the process of conduction, therefore adopt the reflecting means will be through energy gathering cap 1 reflection and the sunlight that converges, converge and reflex on the energy boot media 3 again, because sunlight is converged by twice, therefore its temperature of injecting after the energy boot media 3 is greatly improved, and then conducted by energy boot media 3 again, even if there is aforesaid energy loss, also can make the energy of its conduction play due effect, namely directly be utilized and storage back 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 also inserts by heat-transfer tube 7 or the end near the energy input end of solar generator, can't directly gather under the situation of solar energy at energy gathering cap 1, by the energy input end transmission heat of heat-transfer tube 7 to solar generator 4, thereby guarantee that it continues operation.
As shown in Figure 1, in another embodiment of the present invention, with reference to optical principle of the prior art, can be with energy gathering cap 1 for being the concaver of spherical shape, converge in order to form sun reflection of light, 2 of above-mentioned reflecting meanss are fixed on the cumulative central position of energy gathering cap 1 by the extended pole 8 in energy gathering cap 1 edge, can make like this between itself and the energy gathering cap 1 to keep at a distance, with the convenient angle that converges back reflection light for the second time of adjusting, make and converge the easier realization of reflection twice of above-mentioned sunlight; Place the quantity of aforementioned pole 8 to arrange arbitrarily, be as the criterion reflecting means 2 can be fixed on specified position and keep stable.
Again with reference to shown in Figure 1, be used for the embodiment that the technical solution problem is more preferably in the present invention, the inventor considers that sunlight incident angle all the time is all inequality, the angle that needs constantly to adjust energy gathering cap just can make its concave surface remain at best daylighting position, therefore go out as shown in Figure 2, need be provided for the optical concentration mirror 21 that sunlight is converged in reflection for the second time in the above-mentioned reflecting means 2 on the one hand, need to arrange sunlight direction follower head 22 on the other hand, optical concentration mirror 21 places the below of sunlight direction follower head 22, the effect of this sunlight direction follower head 22 is to be controlled by microprocessor, adjust the real time position of energy gathering cap 1 by three-axis parallel 5, inject direction with sunlight and be consistent, the method for its control is as follows:
Steps A, sunlight direction follower head are exported corresponding optical signal with the angle of sunlight incident to photoelectric conversion module, by photoelectric conversion module optical signal are converted to address signal, and export microprocessor to or temporary address signal calls for microprocessor;
Step B, microprocessor call default azimuthal displacement amount data according to address signal from first data storage device, and from second data storage device, obtain the instant displacement data of following the tracks of displacement actuator, obtain the two difference displacement amount through computing, choose to export to behind the chip port by code translator again and follow the tracks of displacement actuator; In this step, for guaranteeing that above-mentioned difference displacement amount exports the sequential conformity when following the tracks of displacement actuator to, and has a verifying function, microprocessor is before calling default azimuthal displacement amount data from first data storage device, preferably at first send and receive signal and open the chip port that its data receive to following the tracks of displacement actuator, and then choose behind the chip port to following the tracks of displacement actuator output difference displacement amount by code translator.
Step C, tracking displacement actuator drive three-axis parallel 5 according to this difference displacement amount makes energy gathering cap 1 rotate towards set direction, and rotational displacement equates with this difference displacement amount.
Further, above-mentioned three-axis parallel 5 is equipped with actuating motor at least two axles in the three-axis parallel 5, i.e. above-mentioned tracking displacement actuator, and the difference displacement amount that is used for choosing and import according to code translator drives the three-axis parallel motion; Microprocessor is gathered the displacement data of three-axis parallel and is transferred to second data storage device by displacement transducer.According to above-mentioned structure, above-mentioned solar generator 4 can be installed in the below of energy gathering cap 1, and directly place on the installation table top, can reduce the load of energy gathering cap 1 like this, thereby to the requirement of three-axis parallel 5 power, adopt low power motor to drive when reducing its rotation.
With reference to shown in Figure 3, according to another embodiment of the present invention, be the minimizing energy loss that the above-mentioned sunlight that converges through two secondary reflections is tried one's best in conductive process, can directly adopt optical fiber catheter of the prior art as above-mentioned energy boot media 3, namely mention as above-mentioned, optical fiber catheter extends to that the back bifurcated is two-way outside the bottom of energy gathering cap 1; And a part realization two-way optical fiber catheter all has identical or approximate solar energy to conduct, also set up optical prism 6 on the bifurcation site of the fine catheter interior of light requirement, namely the solar energy that will come from reflecting means 2 that act as of this optical prism 6 reflects respectively as for carrying out the heat conduction in the two-way of optical fiber catheter bifurcated, its principle is that optical prism 6 self namely has reflective functions, again can be by light penetration, therefore when it is installed in the crotch of optical fiber catheter with the position that is similar to miter angle, sunlight after converging for twice arrives a back part and is reflected by optical prism 6, wherein one tunnel arrival heat-storing device along optical fiber catheter, another part passes the energy input end that optical prism 6 is directly injected solar generator 4, namely under the situation of 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, to mention as above-mentioned, above-mentioned solar generator 4 can directly adopt stirling generator of the prior art, and to be used for conversion of solar energy be that mechanical energy drives generator operation.And stirling generator be a kind of can be that closing of the energy loops back the hot type motor with the 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 be used as prime mover and had used, and also can be used as refrigerator, heat pump or pressure generator and used.
