Solar Collector and Solar Automatic Tracking Device Using Solar Electricity

摘要

The advantage of using sunlight as lighting is that it can use the natural light of the electric field as it is and save energy. In addition, the use of parabolic mirrors in collecting solar light can be considered to be excellent in terms of equipment and efficiency. However, in collecting light using a parabolic mirror, the loss of light generated by incidence of diagonally collected sunlight from the focal point into the optical cable, the loss of parts due to the solar heat collected at the focal point, and the parabolic mirror to the altitude of the sun. In other words, the external energy, for example, electric energy must be moved as a power source. In order to overcome this disadvantage, we propose a solar collector and solar automatic tracking device using solar electricity. The solar collector collects sunlight through a parabolic mirror and collects light coming from diagonal lines from a focal point with a convex lens, and transmits sunlight by injecting light vertically into an optical cable. The automatic tracking device installs a vertical bar in the parabolic mirror and arranges photoelectric elements around it so that the CPU can calculate the spot where the vertical bar's shadow does not occur and use the vertical motor to track the sun automatically. All power sources used here use the power produced by solar panels installed around parabolic raceways, which can be rotated 180 ° vertically or horizontally to protect the parabolic mirror and reduce the discomfort caused by light reflection. It may be fixed. In addition, high heat is generated at the focal point of the parabolic mirror where solar light is collected. Heat generated at this time may cause a loss due to the heat of the component, and thus a thermoelectric heat pump is used to remove it. The power source for all this is using solar energy too.;By collecting and tracking sunlight in this way, it can automatically track the sun, collect and deliver sunlight maximally without additional energy supply, and reduce heat loss. It is a way to pursue both energy saving and natural light.
