specific Embodiment approach

[0017] figure 1 , 2 The structure of an embodiment of the present invention is shown. As shown in the figure, the solar position finder of the present invention utilizes the light-sensing performance of the photosensitive element to realize the purpose of tracking the sunlight at all times when the whole device is tracking the sun's trajectory on a single axis.

[0018] The present invention includes: a light-shielding body 1 , a first photosensitive element 2 , a dust cover 3 , a base 4 and a second photosensitive element 5 . Among them, the first photosensitive element 2 and the second photosensitive element 5 are blocked by the light-shielding body 1 to ensure that sunlight will not irradiate the two photosensitive elements at the same time; since the photovoltaic power generation system allows an error within 5°, the light-shielding The body 1 is a wedge-shaped body with an included angle of 5° on both sides; the first photosensitive element 2 and the second photosensitiv...

Abstract

The invention provides a sunlight position finder simple in structure and low in cost for a single-axis solar trajectory tracking device. The sunlight position finder mainly comprises a light-shielding body, a first photosensitive element, a dustproof cover, a base and a second photosensitive element; wherein the first photosensitive element and the second photosensitive element are separated by the light-shielding body which is a wedge with two side surface having an intersection angle of 5 degrees; the first photosensitive element and the second photosensitive element are fixed on the base and form an angle of 45 degree with the base; the lead wire of the photosensitive members are led out of the lower portion of the base, and is connected to the single-axis solar trajectory tracking device; the dustproof cover covers the light-shielding body, the first photosensitive element, the base and the second photosensitive element and is entirely transparent. The sunlight position finder user a few components, is low in overall cost, and simple in structure and can precisely control the single-axis solar trajectory tracking.

Description

technical field [0001] The invention relates to the field of angle measurement of sunlight, and is specifically applied to the measurement of sunlight position in a sun tracking device. Background technique [0002] For a long time, the world's energy has mainly relied on fossil fuels such as petroleum and coal. As a one-time non-renewable resource, these minerals have limited reserves, and when burned, a large amount of carbon dioxide is produced, causing the earth's temperature to rise and the ecological environment to deteriorate. According to the forecast of the International Energy Agency, mankind is facing the serious threat of fossil fuel depletion. This global energy crisis has forced governments to invest a lot of manpower and financial resources in research and development of new energy sources, such as solar energy. Solar energy is an inexhaustible clean energy, and the use of solar photovoltaic power generation has very broad application prospects. [0003] The...
