Alignment adjusting device used for radiation sensor on sun follower

The invention relates to an alignment adjusting device used for a radiation sensor on a sun follower. The alignment adjusting device comprises a sensor fixing frame supported on a vertical adjusting base, the vertical adjusting base is supported on a horizontal adjusting base, and a mounting plate is arranged on the horizontal adjusting base. A vertical rotating shaft is arranged on the sensor fixing frame, and the sensor fixing frame can rotate around the vertical rotating shaft in the vertical direction. A horizontal rotating shaft is arranged below the vertical rotating shaft and is perpendicular to the vertical rotating shaft, and the sensor fixing frame can rotate around the horizontal rotating shaft in the horizontal direction. The horizontal adjusting base is provided with a horizontal rotation adjusting mechanism used for adjusting the sensor fixing frame to rotate around the horizontal rotating shaft, and the vertical adjusting base is provided with a vertical rotation adjusting mechanism used for adjusting the sensor fixing frame to rotate around the vertical rotating shaft. The alignment adjusting device is simple and compact in structure, low in cost, convenient to adjust, capable of ensuring that a light spot falls at the center of an alignment base, safe and reliable.
