| 摘要 |
The present invention relates to a new structure of a sunlight tracking device, which can move along and track the daily-changing azimuth angle and seasonally-changing height of the sun, among the components of a solar system (generator which generates electricity by concentrating sunlight) installed at a pole such as a streetlight, a security light, a traffic light, a telephone pole, etc. The sunlight tracking device (300) installed at a pole-installed solar system comprises: a fixed housing (320) which is installed on top of a base frame (310) at one side, wherein the base frame is combined with an installation combining unit (100), and has an X-axis driving shaft (321) rotated around X-axis by a first-axis driving unit (325); a rotary housing (330) which is installed at one side of the fixed housing (320) and rotated forward or backward around the X-axis within a fixed range according to the rotation of the X-axis driving shaft (321); a Y-axis driving shaft (331) which is installed at the rotary housing (330) and rotated around Y-axis, which is different from the direction of the X-axis driving shaft (321) in the fixed housing (320), by a second-axis driving shaft (335); and a solar frame combining unit (340) which is installed on top of the rotary housing (330) containing the Y-axis driving shaft (331) and combined with a bottom part (10) of a solar frame on which a solar cell module (11) is installed. |
