Sun tracking support device for high-concentration module

The utility model discloses a sun tracking support device for a high-concentration module. The sun tracking support device includes at least one group of support units. Each support unit includes two columns, a toque pipe, a swing assembly and an overhead push-pull rod. The torque pipe straddles the top ends of the two columns. The swing assembly is installed in the middle part of the torque pipe. The swing assembly includes a support pipe frame, a gate-shaped frame, a rotation shaft, module supports and ball bearings. The module supports are fixed onto the support pipe frame. Lower ends of the gate-shaped frame are fixed on the middle part of the support pipe frame. Upper ends of the gate-shaped frame are hinged to the overhead push-pull rod. Both ends of the rotation shaft are rotationally mounted in the middle part of the gate-shaped frame through the ball bearings, and the rotation shaft movably penetrates through the middle part of the torque pipe. The gate-shaped frame on the swing assembly is connected with the torque pipe through the rotation shaft; both ends of the rotation shaft are rotationally mounted in the middle part of the gate-shaped frame through the ball bearings; and the ball bearings do not fall off easily. Therefore, the sun tracking support device is of high reliability.
