Abstract

A heliostat includes a pedestal, a transmission system, a heliostat frame assembly, and a mirror assembly. The heliostat frame assembly generally includes a first heliostat frame set and a second heliostat frame set mounted to the transmission system which is mounted upon the pedestal. Each heliostat frame set includes a stackable heliostat inner frame assembly and a stackable heliostat outer frame assembly. Each stackable heliostat inner frame assembly is identical and each stackable heliostat outer frame assembly is identical such that a multiple of heliostat inner frames and a multiple of heliostat outer frames are readily stackable in a nested arrangement for storage and transport.

Claims (27)

1. A heliostat comprising:

a heliostat frame assembly including at least one stackable heliostat inner frame assembly mountable to a stackable heliostat outer frame assembly, said heliostat frame assembly includes a first heliostat frame set having a first stackable heliostat inner frame assembly and a first stackable heliostat outer frame assembly and a second heliostat frame set having a second stackable heliostat inner frame assembly and a second stackable heliostat outer frame assembly, said first stackable heliostat inner frame assembly stackable at least partially within said second stackable heliostat inner frame assembly and said first stackable heliostat outer frame assembly stackable at least partially within said second stackable heliostat outer frame assembly; and

a transmission system mountable to said first stackable heliostat inner frame assembly and said second stackable heliostat inner frame assembly, said transmission system operable to position a mirror assembly mounted to said first heliostat frame set and said second heliostat frame set.

2. The heliostat as recited in claim 1 , wherein said first heliostat frame set is generally parallel to said second heliostat frame set.

3. The heliostat as recited in claim 1 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly are generally trapezoidal shaped in cross-section.

4. The heliostat as recited in claim 1 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly each include a rectilinear back frame and four side frames to define a basket-like configuration.

5. The heliostat as recited in claim 1 , wherein said stackable heliostat inner frame assembly mounts at least partially within said stackable heliostat outer frame assembly.

6. The heliostat as recited in claim 1 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly each include a rectilinear back frame and four side frames, each of said side frames define an obtuse angle relative said respective rectilinear back frame.

7. The heliostat as recited in claim 1 , wherein said at least one stackable heliostat inner frame assembly is mountable to a center section of a said stackable heliostat outer frame assembly.

8. A heliostat comprising:

a first heliostat frame set having a first stackable heliostat inner frame assembly and a first stackable heliostat outer frame assembly;

a second heliostat frame set having a second stackable heliostat inner frame assembly and a second stackable heliostat outer frame assembly, said first stackable heliostat inner frame assembly stackable at least partially within said second stackable heliostat inner frame assembly and said first stackable heliostat outer frame assembly stackable at least partially within said second stackable heliostat outer frame assembly; and

a transmission system mountable to said first stackable heliostat inner frame assembly and said second stackable heliostat inner frame assembly, said transmission system operable to position a mirror assembly mounted to said first frame set and said second frame set.

9. The heliostat as recited in claim 8 , wherein said first heliostat frame set is generally parallel to said second heliostat frame set.

10. The heliostat as recited in claim 8 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly are generally trapezoidal shaped in cross-section.

11. The heliostat as recited in claim 8 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly each include a rectilinear back frame and four side frames to define a basket-like configuration.

12. The heliostat as recited in claim 8 , wherein said stackable heliostat inner frame assembly mounts at least partially within said stackable heliostat outer frame assembly.

13. The heliostat as recited in claim 8 , wherein said stackable heliostat inner frame assembly and said stackable heliostat outer frame assembly each include a rectilinear back frame and four side frames, each of said side frames define an obtuse angle relative said respective rectilinear back frame.

14. A method of assembling a heliostat comprising the steps of:

(A) unstacking at least one stackable heliostat inner frame assembly from a multiple of stackable heliostat inner frame assemblies;

(B) unstacking at least one stackable heliostat outer frame assembly from a multiple of heliostat outer frame assemblies;

(C) nesting the at least one stackable heliostat inner frame assembly at least partially within a central section of the at least one stackable heliostat outer frame assembly to assemble a first heliostat frame set;

(D) unstacking at least one stackable heliostat inner frame assembly from the multiple of stackable heliostat inner frame assemblies:

(E) unstacking at least one stackable heliostat outer frame assembly from the multiple of heliostat outer frame assemblies; and

(F) mounting the at least one stackable heliostat inner frame assembly at least partially within the at least one stackable heliostat outer frame assembly to assemble a second heliostat frame set; and

(G) mounting a transmission system between the first heliostat frame set and the second heliostat frame set; and

(H) mounting a mirror assembly to the first heliostat frame set and the second heliostat frame set.
