Abstract

In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure, a torque tube suspending on the pivot device and aligned within an opening of the support, and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

First claim

What is claimed is:

1. A clamp assembly for a solar module to be configured on a solar tracker system, the assembly comprising:
a thickness of rigid material;
a planar surface region configured from a first portion of the thickness of rigid material, the planar surface region having a length and a width;
a saddle region configured from a second portion of the thickness of rigid material, the second portion being configured within an inner region of the planar surface region, the saddle region having a first surface and a second surface opposite of the first surface, the second surface shaped as a circular arc to be configured over a peripheral portion of a cylindrical torque tube structure;
a first recessed region on a first side of the saddle region and a second recessed region on a second side of the saddle region;
a first opening within the first recessed region; and
a second opening within the second recessed region,
wherein the first recessed region has a slope configured from the saddle region to a first end of the planar surface region;
wherein the second recessed region has a slope configured from the saddle region to a second end of the planar surface region;
wherein the planar surface region and the saddle region are formed from the thickness of rigid material;
wherein the planar surface region has a first part disposed on a first side of the saddle region, and a second part disposed on a second side of the saddle region, the first and second sides of the saddle region being opposing sides of a width dimension of the saddle region;
wherein the circular arc of the saddle region is arranged to accept the cylindrical torque tube structure when a longitudinal axis of the cylindrical torque tube structure in oriented the width dimension; and
the solar module is coupled to the cylindrical torque tube.

2. The assembly of claim 1 wherein the saddle region comprises a key structure to be inserted into a notch structure configured on the peripheral portion of the cylindrical torque tube structure such that the key structure is a male portion to be inserted into a female portion of the notch structure to intimately connect the saddle region to the peripheral portion of the cylindrical torque tube structure.

3. The assembly of claim 1 wherein the first recessed region is a mirror image of the second recessed region.

4. The assembly of claim 1 ,
wherein the saddle region comprises a first wider region within a vicinity of the first recessed region, and a second wider region within a vicinity of the second recessed region.

5. The assembly of claim 1 further comprising:
a U-bolt configured on a lower portion of the peripheral portion of the cylindrical torque tube structure such that a first bolt protrudes through the first opening and a second bolt protrudes through the second opening, and
a first fastener coupled to the first bolt and a second fastener coupled to the second bolt to secure the saddle region to the torque tube structure by sandwiching the torque tube structure between the second surface and a bottom portion of the U-bolt.

6. The assembly of claim 1 ,
wherein the saddle region comprises a first wider region within a vicinity of the first recessed region, and a second wider region within a vicinity of the second recessed region;
wherein the first recessed region, the saddle region, and the second recessed region are configured as an hour glass type shape when viewed from a spatial location normal to the planar surface region.

7. The assembly of claim 1 wherein the thickness of rigid material comprises steel.

8. The assembly of claim 1 further comprising a first border configured on a first edge of the planar surface region and a second border configured on second edge of the planar surface region.

9. The assembly of claim 1 further comprising a first border configured on a first edge of the planar surface region and a second border configured on second edge of the planar surface region; and further comprising a pair of first openings within a vicinity of a first end of the planar surface region and a pair of second openings within a vicinity of a second end of the planar surface region.

10. A clamp assembly for a solar module to be configured on a solar tracker system, the assembly comprising:
a thickness of rigid material;
a surface region configured from a first portion of the thickness of rigid material, the surface region having a length and a width;
a saddle region configured from a second portion of the thickness of rigid material, the second portion being configured within an inner region of the surface region, the saddle region having a first surface and a second surface opposite of the first surface, the second surface shaped as a circular arc to be configured over a peripheral portion of a cylindrical torque tube structure;
wherein the planar surface region has a first part disposed on a first side of the saddle region, and a second part disposed on a second side of the saddle region, the first and second sides of the saddle region being opposing sides of a width dimension of the saddle region;
wherein the circular arc of the saddle region is arranged to accept the cylindrical torque tube structure when a longitudinal axis of the cylindrical torque tube structure in oriented the width dimension;
wherein the saddle region comprises a key structure to be inserted into a notch structure configured on the peripheral portion of the cylindrical torque tube structure such that the key structure is a male portion to be inserted into a female portion of the notch structure to intimately connect the saddle region to the peripheral portion of the cylindrical torque tube structure;
a first recessed region on a first side of the saddle region and a second recessed region on a second side of the saddle region; and
a first opening within the first recessed region and a second opening within the second recessed region;
wherein the first recessed region has a slope configured from the saddle region to a first end of the surface region;
wherein the second recessed region has a slope configured from the saddle region to a second end of the surface region; and
the solar module is coupled to the cylindrical torque tube.

11. The assembly of claim 10 wherein the first recessed region, the saddle region, and the second recessed region are configured as an hour glass type shape when viewed from a spatial location normal to the surface region;
wherein the surface region comprises a planar surface region;
wherein the thickness of rigid material comprises steel;
a first border configured on a first edge of the surface region and a second border configured on second edge of the surface region; and
wherein the surface region comprising the planar surface region configured from the thickness of material extends from a first outer end to a second outer end of the thickness of material.

12. A clamp assembly for a solar module to be configured on a solar tracker system, the assembly comprising:
a thickness of rigid material;
a planar surface region configured from a first portion of the thickness of rigid material, the planar surface region having a length and a width;
a saddle region configured from a second portion of the thickness of rigid material, the second portion being configured within an inner region of the planar surface region, the saddle region having a first surface and a second surface opposite of the first surface, the second surface shaped as a circular arc to be configured over a peripheral portion of a cylindrical torque tube structure;
a first recessed region on a first side of the saddle region and a second recessed regi
