Small-size passive double-shaft solar tracking device

Abstract

The invention provides a solar tracking device, and particularly relates to a small-size passive double-shaft solar tracking device. The small-size passive double-shaft solar tracking device has the technical scheme that a system consists of five parts including a sensor, comparators, a driver, a direct current deceleration motor and a solar panel, wherein the sensor is used for recognizing light intensity, the light intensity change is converted into the photoresistance value change and is then converted into voltage change, the comparators are used for comparing the voltage size in north and south directions and east and west directions, the four voltage comparators are adopted in the small-size passive double-shaft solar tracking device and are used for comparing the voltage in the four directions, in addition, the comparison result is transmitted to the driver, the driver sends out signals to drive the direct current motor to rotate, and the driver drives the motor to rotate according to results obtained by the comparators; the direct current deceleration motor drives shafts to rotate, and the deceleration motor drives the two shafts to rotate according to signals sent out by the driver; the solar panel converts received solar light rays into electric energy, and the solar panel is fixedly arranged on the shafts, and is driven by the motor to rotate in the direction vertical to sunshine. The solar tracking device has the characteristics that the operation is simple and convenient, the manufacturing cost is low, the tracking range is wide, and the like.

Description

technical field [0001] The invention provides a solar tracking device, in particular a small passive dual-axis solar tracking device. Background technique [0002] Solar energy is clean, abundant, renewable and widely distributed. The earth gets 6xl0 energy from the sun every year 17 Kw.h, which is tens of thousands of times more than the total energy consumed by human beings every year, has a huge development prospect. At present, most of the solar panels are arranged in the form of flat panels and fixed angles. Although the fixing method is simple in molding, the utilization efficiency of solar energy is low. [0003] In order to overcome the above problems, the present invention discloses a small passive dual-axis solar automatic tracking device, which can make the solar panel automatically track the light source, perpendicular to the sunlight, improve the utilization rate of solar energy to the greatest extent, and has the advantages of simple operation and low cost. ...
