Support frames for solar trackers
A pier for a solar tracking system includes a bearing housing assembly, a frame, the frame defining an A-profile having a pair of legs and a crown at a center portion thereof, and a mounting bracket, the mounting bracket coupled to a portion of the crown of the frame at a first portion thereof and coupled to a portion of the bearing housing assembly at a second portion thereof.
1. A damper assembly for use with a solar tracker, comprising:
an upper damper mount, the upper damper mount operably coupled to a portion of a torque tube of the solar tracker;
a lower damper mount, the lower damper mount operably coupled to a portion of a pier of the solar tracker, the lower damper mount including an upper plate, a lower plate, and a split collet interposed between the upper plate and the lower plate, the upper plate and the lower plate each having a tapered surface thereon, the tapered surfaces of the upper plate and the lower plate configured to abut corresponding tapered surfaces of the split collet; and
a strut, the strut operably coupled to the upper damper mount at a first end portion thereof and operably coupled to the lower damper mount at a second, opposite end portion thereof,
wherein rotation of the upper damper mount effectuates a compression or an extension of the strut between the upper damper mount and the lower damper mount, and
wherein drawing the upper plate and the lower plate towards one another causes the tapered surfaces of the upper plate and the lower plate to abut the tapered surfaces of the split collet and effectuate a perpendicular translation of the split collet relative to the upper plate and the lower plate.
2. The damper assembly according to claim 1 , wherein an interior surface of the split collet defines a plurality of ridges thereon.
3. The damper assembly according to claim 1 , wherein an outer surface of the split collet includes a hoop disposed therein, the hoop defining an elongated hole therethrough that is configured to receive a portion of a fastener therein.
4. The damper assembly according to claim 1 , wherein the upper plate defines a lower surface, the lower surface including a tab disposed thereon and extending therefrom, the tab including a post disposed thereon that is configured to be operably coupled to a portion of the strut.
5. The damper assembly according to claim 4 , wherein the tab includes a protuberance disposed on a lower surface thereof that is configured to be received within a corresponding bore defined in an upper surface of the lower plate to inhibit movement of the upper plate relative to the lower plate.
6. The damper assembly according to claim 1 , wherein the perpendicular translation of the split collet effectuated by drawing the upper plate and the lower plate towards one another causes the split collet to clamp the portion of the pier of the solar tracker.
7. A damper assembly for use with a solar tracker, comprising:
an upper damper mount, the upper damper mount operably coupled to a portion of a torque tube of the solar tracker;
a lower damper mount, the lower damper mount operably coupled to a portion of a pier of the solar tracker, the lower damper mount including an upper plate and a lower plate, the upper plate defining a lower surface, the lower surface including a tab disposed thereon and extending therefrom, the tab including a post disposed on the tab, the tab including a protuberance extending from a lower portion of the tab, the protuberance configured to be received within a corresponding dimple defined in an upper surface of the lower plate to inhibit movement of the upper plate relative to the lower plate; and
a strut, the strut operably coupled to the upper damper mount at a first end portion thereof and operably coupled to the lower damper mount at a second, opposite end portion thereof, the strut configured to be operably coupled to the post,
wherein rotation of the upper damper mount effectuates a compression or an extension of the strut between the upper damper mount and the lower damper mount.
8. The damper assembly according to claim 7 , further comprising a split collet interposed between the upper plate and the lower plate.
9. The damper assembly according to claim 8 , wherein an interior surface of the split collet defines a plurality of ridges thereon.
10. The damper assembly according to claim 8 , wherein an outer surface of the split collet includes a hoop disposed therein, the hoop defining an elongated hole therethrough configured to receive a portion of a fastener therein.
11. The damper assembly according to claim 8 , wherein the upper plate and the lower plate each have a tapered surface, wherein drawing the upper plate and the lower plate towards one another causes the tapered surfaces of the upper plate and the lower plate to abut corresponding tapered surfaces of the split collet and effectuate a perpendicular translation of the split collet relative to the upper plate and the lower plate.
12. The damper assembly according to claim 7 , wherein the dimple defined in the upper surface of the lower plate passes through the lower plate.
13. The damper assembly according to claim 7 , wherein when the protuberance is received within the corresponding dimple, rotation of the upper plate and the lower plate relative to one another is inhibited.
