Tracker motor support for truss foundations
A truss foundation for supporting single-axis solar tracker drive motors and center structures. An adapter joins a pair of adjacent truss legs and provides a mounting platform to support a drive motor and/or center structure of a solar tracker. The adapter has a pair of connecting portions that are received in the legs of the truss foundation. The adapter may be a unitary structure or consist of a pair of slidably connected members that are joined with fasteners to accommodate truss legs spaced apart at different distances.
1. A truss foundation system for a solar tracker motor comprising:
a pair of truss legs; and
an adapter for joining a pair of truss legs, the adapter comprising:
a first member; and
a second member, wherein the first and second members each terminate in a connecting portion and are adapted to be slidable connected to one another so that the distance between opposing connecting portions is adjustable, wherein each connecting portion is adapted to be received within an end of one of the truss legs and comprises a crimp connector having a plurality of grooves formed in an outer circumference thereof and an alignment tab substantially parallel to the grooves to align a crimper joining the connection portion to one of the truss legs over the plurality of grooves.
2. The truss foundation system according to claim 1 , wherein when slidably connected, the first and second members provide a mounting surface for receiving a tracker drive component.
3. The truss foundation system according to claim 2 , wherein the tracker drive component is selected from the group consisting of a drive motor and a center structure.
4. The truss foundation system according to claim 2 , wherein an axis through each connecting portion intersects at a common point over the mounting surface.
5. The truss foundation system according to claim 1 , wherein the first and second members are adapted to receive at least one fastener passing through them so that they remain interconnected while a distance between their respective connecting portions is adjusted.
6. A tracker motor support comprising:
an elongated main body;
a bridge portion proximate to a middle of the elongated main body;
a pair of connecting portions at distal ends of the elongated main body portion extending away from the elongated body, wherein each connecting portion is adapted to be received in an open end of a truss leg and comprises a crimp connector having a plurality of grooves formed in an outer circumference thereof and an alignment tab substantially parallel to the grooves to align a crimper joining the connecting portion to one of the truss legs.
7. The tracker motor support according to claim 6 , wherein the bridge portion comprises a mounting surface with a plurality of through holes to support a tracker drive component.
8. The tracker motor support according to claim 7 , wherein the tracker drive component is selected from the group consisting of a drive motor and a center structure.
9. A system comprising:
a pair of adjacent truss legs extending above and below ground; and
an adapter joining the pair of adjacent truss legs, the adapter having a bridge portion positioned between a pair of connecting portions, each connecting portion received in one of the adjacent truss legs of the pair, wherein the connecting portions each comprise a crimp connector having a plurality of grooves formed in an outer circumference thereof and an alignment tab on the adapter proximate to each connecting portion that is substantially parallel to the groves on the connecting portion to align a crimper joining the connecting portion to one of the truss legs; and
a tracker drive component attached to the adapter.
10. The system according to claim 9 , wherein the adapter comprises first and second elongated members that terminate at one end in one of the connecting portions and that are adapted to be slidably fit together so that distance between their respective connecting portions may be adjusted.
11. The system according to claim 9 , wherein the adapter comprises a mounting surface with a plurality of through holes to support the tracker drive component.
12. The system according to claim 9 , wherein the tracker drive component is selected from the group consisting of a drive motor and a center structure.
