Embodiment Construction

[0018] like figure 1 As shown, the photoelectric conversion part of the present invention includes: an infrared filter, a visible light anti-reflection film, a double-convex aspheric lens, a photoresistor array and a fixing device, and the visible light anti-reflection film is coated on the double-convex aspheric lens, and the fixing device Infrared filters, biconvex aspheric lenses (both sides coated with visible light anti-reflection coatings) and photoresistor arrays are firmly fixed. The infrared filter is located in front of the double-convex aspheric lens, and the center of the photoresistor array is located at the focal point of the double-convex aspheric lens. The pins of the photoresistor are connected to the control circuit through wires, and the control circuit is connected to the two stepping motors through wires.

[0019] like figure 2 As shown, the functions and relationships of the various parts of the present invention are described. In the present inventio...

Abstract

The invention is a solar tracking locator in energy source technical field for the sunlight collecting system, where the visible light antireflex coating is coated on two surfaces of a biconvex nonspherical len, a fixer fixes an infrared filter, the biconvex nonspherical len, a photosensitive resistor array and a step motor, the infrared filter is located in front of the biconvex nonspherical len, and the center of the photosensitive resistor array is located on the focus of the biconvex nonspherical len; the sunlight firstly passes through the infrared filter, then passes through the visible light antireflex coating, and then passes through the biconvex nonspherical len and focuses on the photosensitive resistor array, a control circuit judges the solar position variation according to the current variation of the photosensitive resistor array and outputs control signals to control the step motor, the step motor regulates the pitching and horizontal angles of the whole system according to the control signals, so as to ensure the system to be right opposite to the sun. And the invention raises visible light collecting efficiency, improves solar tracking accuracy and largely reduces system cost.

Description

technical field [0001] The invention relates to a device in the field of energy technology, in particular to a sun tracking and positioning device used in a sunlight collection system. Background technique [0002] In my country, economically developed cities with strong lighting demand are often located in power-deficient areas, and power supply is tight; and electric energy is a secondary energy source, most of which are generated by non-renewable resources such as coal, natural gas and nuclear energy in my country; in addition, power generation The process often inevitably produces various environmental pollutants. [0003] Sunlight is the cleanest and most energetic natural light source, and it is inexhaustible. Especially under the condition of providing the same illuminance, the heat brought by natural light is less than that of most artificial light sources; energy consumption. At present, most of people's use of sunlight is to take light through glass windows or sk...
