Camera fixing assembly for surveying and mapping of unmanned aerial vehicle

The camera fixing assembly comprises an arc-shaped plate, a protection box and a mounting plate, a sliding plate is arranged at the lower end in the protection box, connecting rods are mounted on the periphery of the bottom end of the sliding plate, and the mounting plate is mounted at the bottom ends of the connecting rods. A fixing plate is mounted at the upper end in the protection box, a sliding groove is formed in the top end of the protection box above the fixing plate, guide rods are arranged on the two sides in the sliding groove, an arc-shaped plate is mounted at the top ends of the guide rods, and a cleaning brush is mounted on one side of the arc-shaped plate. The driving motor works to drive the disc to rotate, so that the guide rod is driven to rotate in the sliding groove, then the arc-shaped plate is driven to rotate, finally, the sweeping brush sweeps the surface of the camera, impurities or mist are swept away, surveying and mapping work is well guaranteed, and therefore the problem that clea
