Abstract
The invention discloses a scale for solar tracking deviation. The scale comprises a collimation cylinder, a conical tube and a base, wherein the collimation cylinder is vertically arranged in the center of the base; a small-diameter opening of the conical tube is upward, and the conical tube is sleeved on the collimation cylinder; the inner wall of the conical tube and the outer wall of the collimation cylinder are in interference fit; scale marks are formed on the outer surface of the conical tube; installation holes are formed in the base; and the collimation cylinder is made of stainless steel. When incident sunlight is not parallel to the collimation cylinder, the collimation cylinder shades the sunlight to generate a shadow, the shadow is projected to the conical tube, the length of the shadow on the outer surface of the conical tube is measured, and the solar tracking deviation of a biaxial tracking system is calibrated. The scale is simple in structure, convenient to install, accurate in calibration, easy, general, convenient to produce, low in cost and applicable to widely popularize.
Description
Technical field
The present invention relates to a kind of scale of sun tracing deviation.
Background technology
Sun power is the regenerative resource of the abundant and clean environment firendly of a kind of reserves; Its application prospect is very wide; Solar energy concentration generating system is an important way of utilizing sun power; It requires tracker to have the characteristics of precision height, good stability; The double-axis tracking system is the most effective solar tracking automatic tracking system of the maximum tracking of following range that is widely used in solar energy concentration generating system; The characteristic that but sun power has that energy density is little, the illumination process is discontinuous, direction of illumination and intensity constantly change in time makes and fully collects and efficiently utilize sun power that certain degree of difficulty is arranged that research data shows the increase along with the tracing deviation of double-axis tracking system; The optics of dish formula optically focused heat generating system and light gathering photovoltaic power generating system blocks the efficient straight line and descends, and the sun tracing deviation of therefore accurate measurement and demarcation double-axis tracking system and precision are for the efficient that significantly improves solar energy concentration generating and effectively utilize solar energy resources to have great significance.
At present, also have some to be applied to the sun tracing deviation caliberating device that the double-axis tracking system mentions problem more than being used to solve on the market, thereby but device volume is huge, complex structure, inconvenient installation are difficult for carrying out batch detection and demarcation.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of simple general use, easy for installation, simple in structure, demarcate the scale of sun tracing deviation accurately.
Technological means of the present invention is following:
A kind of scale of sun tracing deviation comprises: collimation tube, tapered tube and base; Said collimation tube vertically is located at the center of said base; Said tapered tube smaller diameter end opening is socketed on the collimation tube up; The outer wall interference fit of the inwall of said tapered tube and collimation tube; The outside surface of said tapered tube is provided with scale mark; Said base is provided with mounting hole;
Further, said collimation tube is made up of stainless steel.
Owing to adopted technique scheme; The scale of a kind of sun tracing deviation provided by the invention; Through adopting integral structure and the tapered tube outside surface constitute by collimation tube, tapered tube and base to be provided with scale mark, utilize when incident sunshine and collimation tube are not parallel keep the sun off generation shade and projecting on the tapered tube of collimation tube; And then the shade length of measuring on the tapered tube outside surface is demarcated the sun tracing deviation of double-axis tracking system; Simple in structure, easy for installation, demarcate accurately, simple general use, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.

Fig. 2 is the structural representation that the double-axis tracking system of scale according to the invention is installed.
Among the figure: 1, collimation tube, 2, scale mark, 3, base, 4, mounting hole, 5, tapered tube, 6, the scale of sun tracing deviation, 7, the four-quadrant photoelectric sensor, 8, follow-up control apparatus, 9, biaxial tracker.
Embodiment
In conjunction with accompanying drawing the present invention is elaborated:
The scale of a kind of sun tracing deviation as shown in Figure 1 comprises: collimation tube 1, tapered tube 5 and base 3; Said collimation tube 1 vertically is located at the center of said base 3; Said tapered tube smaller diameter end opening is socketed on the collimation tube up; The outer wall interference fit of the inwall of said tapered tube and collimation tube; The outside surface of said tapered tube 5 is provided with scale mark 2; Said base 3 is provided with mounting hole 4; Further, said collimation tube 1 is made up of stainless steel.
The double-axis tracking system of this caliberating device of installation as shown in Figure 2 comprises scale 6, follow-up control apparatus 8 and the four-quadrant photoelectric sensor 7 of biaxial tracker 9, sun tracing deviation.During the double-axis tracking system works; Send trace command by follow-up control apparatus 8; Biaxial tracker 9 is carried out and is followed the tracks of action; If the collimation tube 1 that the accurate then scale 6 of sun tracing deviation of tracking is provided with is parallel with the incident sunshine; Keep the sun off and produce shade and project on the tapered tube 5 that the scale of sun tracing deviation is provided with if to have tracing deviation be collimation tube 1 with the not parallel then collimation of incident sunshine tube 1; Thereby and then measure the sun tracing deviation that shade length reads biaxial tracker 9 through the scale mark 2 that tapered tube 5 outside surfaces are provided with, the output signal through adjustment four-quadrant photoelectric sensor 7 makes the parallel calibration that realizes the double-axis tracking system with the incident sunshine of collimation tube 1.The scale of a kind of sun tracing deviation provided by the invention; Through adopting the integral structure and the tapered tube outside surface that constitute by collimation tube, tapered tube and base to be provided with scale mark; Utilize when incident sunshine and collimation tube are not parallel; The collimation tube keeps the sun off and produces shade and project on the tapered tube, and then the shade length of measuring on the tapered tube outside surface demarcates the sun tracing deviation of double-axis tracking system, simple in structure, easy for installation, demarcate accurately, simple general use; Not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
