Abstract: A synchronous driving device includes a driving source and a driving drive mechanism. The driving drive mechanism includes a first housing and a driving transmission assembly arranged in the first housing and engaged in transmission. The driving transmission assembly includes an input shaft, a first output shaft, a second output shaft and a third output shaft. A driving end of the driving source is connected with the input shaft. The third output shaft is perpendicular to the first output shaft and the second output shaft. The first output shaft, the second output shaft and the third output shaft are configured to be driven by the driving source to rotate synchronously. A photovoltaic tracking bracket system having the synchronous driving device is also disclosed.

Abstract: A photovoltaic support spindle, including at least a long shaft, where the long shaft includes a first flat panel, a second flat panel, a third flat panel, a first arc panel, a second arc panel, and a third arc panel; the first arc panel is connected between the second flat panel and the third flat panel; the second arc panel is connected between the first flat panel and the second flat panel; and the third arc panel is connected between the first flat panel and the third flat panel. The first arc panel, the second arc panel and the third arc panel are three arc surfaces distributed on a same cylindrical surface. The disclosure saves a material, reduces a cost and improves a bending resistance.

Abstract: Multi-point parallel synchronous drive device, which includes a drive mechanism and several stages of driven mechanisms drivingly connected. The drive mechanism comprises a first power output for rotatably connecting with a power output shaft, and a second power output disposed below the first power output and parallel to the first power output along a power output direction. The several stages of the driven mechanism are arranged at intervals in the power output direction. The second power output of the drive mechanism is drivingly connected with a power input of the adjacent driven mechanism along the power output direction, and the adjacent two-stage driven mechanisms are drivingly connected along the power output direction. The driven mechanism at any stage comprises a power output for rotatably connecting with the power output shaft. The device can be applied to the a solar tracking system, with the main shaft as the power output shaft.

Abstract: A torque tube with a pentagonal cross-section includes a tube body and a cavity disposed in the tube body. The cross-section of the tube body of the length direction is a convex pentagon including a first side, a second side, a third side, a fourth side, and a fifth side that are connected end to end in a circumferential direction to form a closed structure. The tube body is a symmetrical structure with a perpendicular bisector of the third side as an axis, such that the second side is symmetrical with the fourth side, the first side is symmetrical with the fifth side, and the second side and the fourth side are vertically connected to the third side. A solar structure is further provided. The special pentagonal structure of the torque tube provides an additional cross-section for selection while ensuring strength and flexural performance and saving on material costs.
