Drive mechanism for a solar concentrator assembly

A drive mechanism for a linear solar concentrator assembly which includes an elongate reflector support frame which is rotatable about an axis which is parallel to the length of the frame and is defined by a support for the frame, the drive mechanism comprising:

• a first elongate arm fixable at one end to the frame for rotation about the axis with the frame;
• a second elongate arm rotatable at one end about the axis independently of the first arm,
• a first reversible linear drive device coupled between the second arm and the first arm which is operable to rotate the first arm about the axis relative to the second arm;
• and
• a second reversible linear drive device coupled between the support and the second arm which is operable to rotate the second arm about the axis;
• wherein the first and second rams are positioned to apply forces in substantially the same plane normal to the axis.

A drive mechanism for a linear solar concentrator assembly which includes an elongate reflector support frame which is rotatable about an axis which is parallel to the length of the frame and is defined by a support for the frame, the drive mechanism comprising:

• a pair of spaced apart first elongate arms fixable at one end to the frame for rotation about the axis with the frame;
• a second elongate arm rotatable at one end about the axis independently of the first arm, the second elongate arm being at least partly rotatable between the first elongate arms;
• a first reversible linear drive device coupled between the second arm and the first arms which is operable to rotate the first arms about the axis relative to the second arm;
• and
• a second reversible linear drive device coupled between the support and the second arm which is operable to rotate the second arm about the axis.
