A sun position detection device for sun automatic tracking

The utility model relates to a sun position detection device for sun automatic tracking has a first light section of thick bamboo and the second of leading to and leads to a light section of thick bamboo, and two lead to the hollow cylindricality structures that a light section of thick bamboo be coaxial setting, and the last bottom surface that the second leads to a light section of thick bamboo is connected and the intercommunication with the first lower bottom surface that leads to a light section of thick bamboo, and diameter that the second leads to a light section of thick bamboo is greater than the first diameter that leads to light tin, is equipped with one on the last bottom surface of a logical smooth section of thick bamboo and leads to the unthreaded hole, arrange the first photosensitive sensor of group on the lower bottom surface of the logical light section of thick bamboo of second, the first lateral wall that leads to a light section of thick bamboo and the logical light section of thick bamboo of second is the light enclosed construction. The utility model discloses measuring sun position that can be more accurate, can with detect the sun azimuth deviation circumstances convert into directly perceivedly the sun elevating angle and the ascending angular shift in azimuth side, detectivity high, can shield the sun position detection device of the interference of environment light, can detect and can follow the tracks of solar device by controlling means for sun tracker provides one.
