Abstract
A multi-scissor jack-operated single-shaft solar tracking apparatus. A scissor jack is provided at regular intervals on a rotation beam of the single-shaft tracking solar support, thereby forming a multi-drive rotation. Lifting screw of each scissor jack is connected by a drive shaft so as to be lifted in synchronization. One of the scissor jacks can be driven by a motor, and the lifting screws of the other scissor jacks are driven by the transmission shaft, thereby synchronously driving the rotation beam of the single-shaft tracking solar support to rotate. The scissor jacks can be driven by manpower, in order that the angle of the tracking solar support can be adjusted by hand.
Claims3
A solar tracking apparatus comprising:
- a master scissor jack driven manually or by a motor, the master scissor jack having a lifting screw,
- one or more slave scissor jacks each having a lifting screw,
- a drive shaft connecting the lifting screw of the master scissor jack and the lifting screw of the slave scissor jack,
- a rotating beam having a plurality of support brackets,
- one or more photovoltaic modules each having one or more supporting beams,
- one or more rockers each connecting the rotating beam either to the master scissor jack or to the driven scissor jack, and
- a plurality of supporting scaffolds,
- wherein:
- the master scissor jack and the slave scissor jack are individually fixated on the supporting scaffold;
- the rotating beam is secured by the support brackets to the supporting scaffolds;
- the master scissor jack and the slave scissor jack is lifted in synchronization through the drive shaft;
- the master scissor jack and the slave scissor jack control the rotation of the rotating beam through the rocker, and
- the rotating beam is connected to the supporting beam thereby controlling the rotation of the photovoltaic module;
