Clamp assembly for solar tracker
In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first anchoring region and a 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 and 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.
1. A clamp assembly for a solar tracker comprising:
a frame having a loop structure defining an opening, the opening including a first stop region and a second stop region, and at least one flat region extending between the first stop region and the second stop region;
an anchor region configured to connect the frame to a support; and
a pivot device operably connected to the frame and configured to support a torque tube and enable the torque tube to swing within the loop structure.
2. The clamp assembly of claim 1 , wherein the opening defined by the frame is heart shaped.
3. The clamp assembly of claim 1 , wherein the opening defined by the frame is butterfly shaped.
4. The clamp assembly of claim 1 , wherein the pivot device includes a pin.
5. The clamp assembly of claim 4 , further comprising a sleeve mounted in the fame and configured to receive the pin.
6. The clamp assembly of claim 4 , further comprising a bearing mounted in the fame and configured to receive the pin.
7. The clamp assembly of claim 4 , further comprising a U-bolt structure secured to the pin and configured to receive the torque tube.
8. The clamp assembly of claim 7 , wherein the U-bolt structure includes a clamp member configured to receive the pin.
9. The clamp assembly of claim 8 , wherein the clamp member includes a protrusion configured to engage an opening formed on the torque tube.
10. The clamp assembly of claim 4 , wherein the first stop region limits movement of the torque tube, rotating about the pin within in the opening, in a first direction.
11. The clamp assembly of claim 10 , wherein the second stop region limits movement of the torque tube, rotating about the pin within the opening, in a second direction.
12. A solar tracker comprising:
a plurality of clamp assemblies, each clamp assembly including a frame having a loop structure defining an opening, the opening including a first stop region and a second stop region, and at least one flat region extending between the first stop region and the second stop region and an anchor region configured to connect the frame to a support;
a torque tube extending between the plurality of clamp assemblies; and
a pivot device operably connected to the fame and configured to support the torque tube and enable the torque tube to swing within the loop structure between the first stop region and the second stop region.
