Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
In order to realize the collection of the sunshine to X-direction, Y-direction and Z-direction, improving the accurate location of solar tracking system, embodiments providing a kind of for the light measurer in solar tracking system, see Fig. 1, Fig. 2 and Fig. 3, described below:
This light measurer comprises: photovoltaic battery panel 1, and the X-axis and Y-axis of photovoltaic battery panel 1 are respectively arranged with Photometer 2, and Photometer 2 comprises: Photometer framework 3, and Photometer 3 is the rectangular parallelepiped of a upper end open, all the other five face lucifuges.The side surface upper part of Photometer 3 is provided with lens groove 31, lens groove 31 is respectively arranged with lens approach rail 32 and lens carrier 33; Rectangle convex lens 34 are provided with between lens approach rail 32 and lens carrier 33.Be provided with optical filtering board slot 35 in the middle part of the side of light filter 3, optical filtering board slot 35 be respectively arranged with filter approach rail 36 and filter support 37, between filter approach rail 36 and filter support 37, be provided with filter 38; The bottom of Photometer 3 is provided with a convergent hole 39, and the position of convergent hole 39 is corresponding with the focus of rectangle convex lens 34, convergent hole 39 is provided with the first phototriode 40; The Z axis of photovoltaic battery panel 1 is also provided with the second phototriode 41.
Wherein, this Photometer 2 is symmetrical, filter 38 can direct in optical filtering groove 35 by filter approach rail 36 on left and right side frame smoothly easily, and filter 38 is stuck on filter support 37, this structure is convenient to install and the rear filter 38 of installation is more firm, rectangle convex lens 34 can direct in lens groove 31 by the lens approach rail 32 on same left and right side frame, rectangle convex lens 34 are stuck on lens carrier 33 simultaneously, and rectangle convex lens 34 are rigidly mounted in lens groove 31; Convergent hole 39 is focal positions of rectangle convex lens 34, and place light-sensitive semiconductor element, i.e. phototriode 40, the upper frame of Photometer can prevent the slide anteroposterior of rectangle convex lens 34.
During specific implementation, the second phototriode 41 on Z axis, in order to judge the presence or absence of sunshine; X-axis Photometer is a rectangle Photometer paralleled with terrestrial meridian; Y-axis Photometer is the rectangle Photometer paralleled with terrestrial latitude line.
The principle of work of this Photometer 2 is as follows: the principle of work utilizing convex lens, the refraction of parallel rays planoconvex lens can intersect at a point later, this point is exactly the focus of convex lens, and the focus point shape of convex lens is only relevant with the curvature of convex lens with size, has nothing to do with the shape of convex lens.Convex lens in this Photometer are as material with epoxy resin, rectangle convex lens 34 are made, namely be a middle part for complete convex lens, when there being directional light to irradiate, although be the convex lens of strip, but its focus remains a round dot, and be the focus of lens, due to employing is strip convex lens, the light of warp direction can be pooled to so as far as possible at warp direction, light can converge to focus, phototriode 40 is placed in this focus, just the directional light of the sun can be responded to, other scattered lights will be filtered out by filter, due to rectangle convex lens 34 be strip and with through line parallel, so this inductive head only responds to the vertical light of warp direction, in order to adjust the horizontal angle of photovoltaic cell 1, as a same reason, Y-axis Photometer has come the azimuthal induction of sunshine.
More than the total of Photometer 2, this structure complete judge sunshine presence or absence, at the position of the position of warp and horizontal angle, dimension and the Ye Cheng elevation angle, position angle.For whole solar tracking system provides the process of information employing.
Wherein, the shape of lens groove 31, lens approach rail 32, lens carrier 33, optical filtering board slot 35, filter approach rail 36, filter support 37, structure and material are known in this area, and the embodiment of the present invention does not limit this.
During specific implementation, the model of the embodiment of the present invention to above-mentioned device does not limit, as long as can complete the device of above-mentioned functions.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, the invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
