Solar elevation tester

Abstract

The invention discloses a solar elevation tester which mainly comprises a measuring stick, a measuring disk and a longitudinal regulating nut, wherein the measuring stick has a special length comprising four grades: 20mm, 50mm, 100mm and 200mm, different measuring sticks are selected according to different solar elevations; the measuring disk has a diameter of 160mm and is divided into four regions respectively corresponding to the measuring stick; 1 / 4 concentric circles with different diameters are marked in each region, elevation degrees are marked on the concentric circles, the solar elevation can be conveniently read through the projection of the measuring stick; and the longitudinal regulating nut is used for regulating the measuring disk so as to be leveled with the measuring disk. The solar elevation tester has the minimum resolution of 0.2 and the elevation measurement range of 14.0 DEG-90.0 DEG. The invention has the characteristics that the measuring disk is divided into the regions, thus the radius of the measuring disk is effectively reduced, and the solar elevation tester is convenient for carrying; partitioning measurement is adopted, the radiuses of the concentric circles in different regions are different, thus the measurement precision of the solar elevation is increased; and the cost performance is high, the design cost of the solar elevation tester is low, and the longitudinal regulating nut is provided, thus personal errors are reduced.

Description

technical field [0001] The invention relates to a device for measuring the elevation angle of the sun, in particular to an instrument for measuring the elevation angle of the sun. Background technique [0002] In recent years, solar energy has attracted more and more people's attention, and some solar energy products have gradually entered people's lives, such as solar street lights, solar water heating, and solar photovoltaic power generation. However, the measurement of some parameters related to the sun, such as the sun's elevation angle, spectrum, energy density, etc., is still in the Institute of Precision Measurement, mainly due to the high price and complex structure of such precision measuring instruments. For some general research institutes and individuals interested in solar energy utilization, it is undoubtedly an astronomical figure. The lack of low-cost instruments seriously hinders the development of the solar energy industry. Contents of the invention [0...
