Go out as shown in Figure 2 A and 2B, reflector element 204 can comprise generally mirror assembly, torque tube 202 and the connector 208 in the instruction of 206 places.(be appreciated that, in Fig. 2 A and 2B, mirror 104 is depicted as transparent, with the element for after contributing to illustrate.) each support arm 102, and two braces 112 that are attached to support arm, and connector 208 forms truss 210 together.Connector 208 is against torque tube 202, thus reinforcement truss 210, and simultaneously for supporting torque tube, thereby contribute to the motion of torque tube to be transferred to mirror 104.Connector 208 can be formed by a kind of, two or more assemblies.For example, some embodiments of (seeing Fig. 2 B) comprise torque tube and are hereinafter referred to as assembly and the torque tube between the support arm of A shape plate and are hereinafter referred to as the assembly between the brace of U-shaped rod.
Fig. 3 A illustrates adaptive for supporting 202, two mirrors of torque tube of two mirrors for example to have three U-shaped rods and three the A shape plates 306 in every half of torque tube 202, and this torque tube 202 is adaptive for supporting the support arm of each mirror.As above stated, the quantity of support arm can be 2 or 4 or any other numeral.In some embodiments, torque tube 202 can also comprise a pair of azimuth axis supporter 310 and elevation angle tip drivers supporter 312.
Torque tube 202 can be the hollow tube at two ends band opening.Torque tube can be made up of the material of any appropriate, and have enough mechanical strengths so that the mechanical energy in the form of rotatablely moving is transferred to mirror assembly 206 not experience degree be enough to can adverse effect the distortion of operation of mirror.
As shown in Fig. 3 A-3C, can limit along the position of the connector of torque tube 208 curvature (, the concavity of the mirror at least one axis) of mirror, this can limit the focal length of mirror.In some embodiments, connector 208 can be U-shaped rod 304 and A shape plate 306.U-shaped rod 304 can design and be adaptive for accepting and be attached to the end of brace, and the support arm by from heliostat of brace launches.A shape plate 306 can be attached to support arm itself, preferably wedges in the groove of support arm.At the sectional view of U-shaped excellent 304 and the A shape plate 306 that expand shown in Fig. 3 B.
