Solar module support device

A solar module support device is formed by at least one group of support units and used for supporting a solar module. Each support unit comprises at least two columns for supporting a torque tube, a torque tube motor for driving the torque tube to rotate is arranged at one end of the torque tube, a swinging assembly at the middle portion of the torque tube comprises a longitudinal shaft and two supporting rods, the longitudinal shaft penetrates through the middle portion of the torque tube, and the two support rods are arranged at on two sides of the torque tube and vertically hinged on the longitudinal shaft in crossed mode. The lower ends of the support rods are respectively connected onto a solar module fixing support, the upper ends of the support rods are connected with a movable rod, a push rod driven to extend and contract by a lead motor is arranged on the torque tube, the other end of the push rod is connected at the front end of the movable rod, and the rear end of the push rod is hinged with the t
