Abstract
Disclosed is a heliostat assembly having a circular, ring mounted reflector which is driven and supported by an arrangement of elongated levers. A pair of levers are spaced apart and pivotally mounted at their lower ends, and have upper ends which are linked to the heliostat ring at diametrically opposite horizontally spaced location, by way of ball-and-socket type joints. A third lever has a first end similarly mounted to the heliostat ring at a location below and mid-way between the connections of the lever pair. Assuming the assembly is located in a south-facing heliostat field, the third lever extends generally southward to its second end which is mounted for movement about a horizontal axis. By driving each one of the lever pair in opposite directions the heliostat may be turned for solar tracking. The heliostat may also be driven to a protective stow position by pivoting the lever pair southwardly together in parallel, until the heliostat is turned to a horizontal, face-down position.
