Abstract

An apparatus for converting dynamic solar energy to controllable one for cooking, electric generation, lighting, etc is characterized by that a large parabolic reflector is used for tracking the sun and gathering the sunlight to a focuse point, a small parabolic reflector at said focus point is used to make the gathered sunlight become dense parallel light beams, and serially connected 4 right-angle turning units are used to convert the direction-changing parallel light beams to the dense ones with the direction controlled manually.

Description

Moving solar energy is transformed into the device of controllable solar energy

The present invention relates to a kind of will move solar energy be transformed into controllable solar can device

The existing main device of solar energy that uses has, semi-conducting material photoelectric conversion device, direct-type solar water heater, rice steaming box etc., but they all exist certain shortcoming.As the optical semiconductor electrical switching device, material cost height, conversion ratio are only about 17%; The direct-type solar water heater, though cost is lower than the former, the practicality dullness, the invalid reflection at inside and outside four interfaces of glass of heat insulation layer will take place in its incident ray again, so its thermal efficiency is also only below 65%.Become solar energy therefrom and can not get popularizing the main cause of utilizing.

Purpose of the present invention is exactly at above-mentioned shortcoming, provides a kind of practical degree wide, and manufacturing cost is low again, and thermal efficiency height, and easy to use again will move the device that solar energy is transformed into the controllable solar energy.

In order to achieve the above object, the present invention is by the following technical solutions: collect in focus after at first will dredging the parallel sunray reflection of formula with the paraboloidal concave surface of big circle that can follow the tracks of the sun, be that the paraboloidal convex surface of small circular of virtual focus is reflected into close formula parallel rays again with the light that accumulates with this real focus then, it promptly is exactly circular light harvesting bundle, after promptly being exactly the turning of light right-angled bend device by four incident raies and the rectangular level crossing reflector of reflection ray at last, arrive desired location.Because every light right-angled bend device all is made up of two pipes that plane mirror is connected with the right angle, and the junction between per two light right-angled bend devices can light beam be that axle rotates, promptly form three-dimensional light path, so can be arbitrarily directed and become controlled at the emitted light beam of the light right-angled bend device of the last.

The present invention has the following advantages: the solar energy of moment break-in can be transported to fixed position arbitrarily 1.; 2. the luminous energy of gained is concentrated, and the temperature height is so practical degree is wide; 3. whole light transmission course all is a usable reflection, and promptly energy loses seldom, so thermal efficiency height; 4. all material is based on common reflecting material, so at the bottom of the cost; 5. owing to simple in structure, so stable performance.

Cooking during the present invention can be used for living cooked, the heating of solar electrical energy generation, room lighting, can replace conventional energy resource in the industry, can be used to steady standard in the military affairs and hits enemy's flying object etc. soon.

The present invention is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 for of the present invention will move solar energy be transformed into controllable solar can device the circular paraboloidal line of centres of a big young waiter in a wineshop or an inn and the tracking sun through section plan that axis became; Accompanying drawing 2 is for setting the median plane cutaway view through the framework of axle and latitude axle.

As shown in Figure 1, of the present invention will move solar energy be transformed into controllable solar can device mainly by the parabolic convex surface reflector of the parabolic concave surface reflector 2 of big circle, small circular 1, four light right-angled bend devices 3 and 5 with other two turning devices that do not draw in the drawings be located at forming through spindle nose 6 (one of them) by two of this reflector center of gravity on the big parabolic reflector 2 through axis (chain-dotted line among the figure).Every light right-angled bend device all is made up of two pipes that are slightly larger than the light harvesting beam diameter and plane mirror 4, and wherein two pipes join with the right angle, and minute surface is located on the vertical plane of right angle bisector plane, and satisfies the light harvesting bundle and all reflect.First light right-angled bend device 3 is located at the line of centres between big young waiter in a wineshop or an inn's parabola with on the intersection point of axis, and an end standard of turning device is to little parabolic reflector 1, and other end standard is to wherein once spindle nose 6.Second light right-angled bend device 5 be located at beyond the reflecting layer of big parabolic reflector through spindle nose with interior on the intersection point of axis and latitude axis, and an end standard of turning device is to the light ejecting end of first turning device 3, and join connection to change the crack cover, the other end is the wherein end of the ejecting end standard of light to the latitude axle, third and fourth light right-angled bend device continue with second successively cover join and be connected into three-dimensional light path.Its major technique structure and light reflection process be, the concave surface of the big relatively parabolic reflector 2 of the convex surface of little parabolic reflector 1, and the virtual focus of little parabolic reflector 1 is located at the real focus of big parabolic reflector 2 and is overlapped (O point among the figure).As F as shown in the figure ₁And F ₂After any two parallel sunrays incide big reflector 2, be reflected and converge to little reflector 1, because the big paraboloidal focus of young waiter in a wineshop or an inn's reflector coincides together, so little reflector 1 can be reflected into parallel intensive light to the whole light that pool again, promptly be exactly the light harvesting bundle, inject first light right-angled bend device 3 then, after 3 right-angled bends of turning device, inject second turning device 5 again, and head-on penetrate after the right-angled bend again.Since the beam center line that first turning device 3 reflects with through dead in line, so the beam direction that first reflector 3 penetrates can not change because of the rotation through axle.In like manner the beam direction that reflects of the second turning device 5 can not change because of the rotation of latitude axle yet.Become therefrom, no matter how reflector 2 to turn to, the beam direction that turning device 5 is head-on penetrated remains unchanged, and to be subjected to the people be the light beam that controls direction through penetrating behind two light right-angled bend devices, just can becoming again at last.

As shown in Figure 2, of the present invention will move solar energy be transformed into controllable solar can the longitude and latitude axle framework of device by being located at forming on the rectangle frame 1 through axis hole 4 (two) and latitude spindle nose 2 (two), it is through

axis

5 and 3 orthogonal intersecting of latitude axis, and latitude axis 3 departs from the center in edge.Two being provided in respectively in axis hole 4 through spindle nose 6 in Fig. 1, the latitude spindle nose 2 on the rectangle frame 1 sets on the unillustrated in the drawings base support.When the sun rotates from east orientation is western, parabolic reflector among Fig. 1 can be that axle is followed the tracks of rotation through axis just, in tracing process, when the extended line of the paraboloidal line of centres of a big young waiter in a wineshop or an inn and solar orbit break away from, parabolic reflector among Fig. 1 can the latitude axis be that axle connects the frame rotation just, thereby makes extended line and solar orbit not to break away from.

Of the present invention will move solar energy be transformed into controllable solar can device, applicable to preparing food in the life cook, generating, inner room illuminating and heating; Industrial alternative conventional energy resource; Can hit flying object etc. on military.
