Systems and methods of automated deployment of mounting devices for photovoltaic modules for solar plant installation
Automated systems and methods for deployment of mounting tubs that support photovoltaic modules are provided in which a feeder assembly includes a screw thread assembly and a pivot arm. The screw thread assembly has at least one rotatable threaded component, and two such components in exemplary embodiments, positioned within the feeder assembly. The rotatable threaded component supports the stack of mounting tubs and rotates to separate the individual mounting tub from the stack of mounting tubs and lower the individual mounting tub onto the pivot arm. The pivot arm is configured to interact with an individual mounting tub and pivots to dispense the individual mounting tub onto a mounting surface. A sensor may be provided to detect the positions of the individual mounting tubs as they are moved, and a control system communicates with the sensor and the feeder assembly. The feeder assembly and a hopper holding the stack of mounting tubs may be mounted on an autonomous cart.
1. An automated system for deployment of mounting tubs supporting photovoltaic modules, comprising:
a feeder assembly including a screw thread assembly and a pivot arm having two arms;
the screw thread assembly having at least one rotatable threaded component positioned within the feeder assembly, the at least one rotatable threaded component supporting the stack of mounting tubs;
the two arms forming a profile configured to engage with indents defined in a rim of an individual mounting tub;
wherein the at least one rotatable threaded component rotates to separate the individual mounting tub from the stack of mounting tubs and lower the individual mounting tub onto the pivot arm; and
wherein the pivot arm pivots to dispense the individual mounting tub onto a mounting surface.
2. The automated system of claim 1 wherein the at least one rotatable threaded component comprises two rotatable threaded components.
3. The automated system of claim 2 wherein the two rotatable threaded components support the stack of mounting tubs while separating and lowering the individual mounting tub.
4. The automated system of claim 1 wherein the two arms are joined in a U-shape.
5. The automated system of claim 1 further comprising one or more sensors configured to detect positions of one or more individual mounting tubs.
6. The automated system of claim 5 further comprising a control system in communication with the feeder assembly and the one or more sensors.
7. The automated system of claim 1 further comprising a hopper configured to hold the stack of mounting tubs and align the stack of mounting tubs with the feeder assembly.
8. The automated system of claim 7 further comprising an autonomous cart, wherein the hopper is mounted on the autonomous cart.
9. The automated system of claim 8 wherein the feeder assembly is mounted on the autonomous cart.
10. An automated method of deploying mounting tubs supporting photovoltaic modules, comprising:
stacking mounting tubs on a hopper;
separating a first mounting tub and lowering the first mounting tub onto a pivot arm having two arms such that the two arms engage with indents in a rim of the first mounting tub; and
dispensing the first mounting tub onto a mounting surface.
11. The method of claim 10 wherein the separating and lowering steps comprise rotating at least one threaded component.
12. The method of claim 10 wherein the dispensing step comprises pivoting the pivot arm to lower the first mounting tub onto the mounting surface.
13. The method of claim 12 further comprising pivoting the pivot arm so it is clear of the first mounting tub.
14. The method of claim 13 further comprising separating a second mounting tub and lower the second mounting tub onto the pivot arm.
15. The method of claim 14 further comprising dispensing the second mounting tub onto the mounting surface.
16. The method of claim 15 further comprising dispensing the first and second mounting tubs in a row with specified spacing within the row.
17. An automated system for deployment of mounting tubs supporting photovoltaic modules, comprising:
a hopper configured to hold a stack of mounting tubs;
a feeder assembly aligned with the hopper, the feeder assembly including a screw thread assembly and a pivot arm having two arms joined in a U-shape;
the screw thread assembly having at least one rotatable threaded component positioned within the feeder assembly, the at least one rotatable threaded component supporting the stack of mounting tubs;
the pivot arm being configured to interact with an individual mounting tub;
wherein the at least one rotatable threaded component rotates to separate the individual mounting tub from the stack of mounting tubs and lower the individual mounting tub onto the pivot arm; and
wherein the pivot arm pivots to dispense the individual mounting tub onto a mounting surface.
18. The automated system of claim 17 further comprising an autonomous cart, wherein the hopper and the feeder assembly are mounted on the autonomous cart.
19. The automated system of claim 17 further comprising one or more sensors configured to detect positions of one or more individual mounting tubs and a control system in communication with the feeder assembly and the one or more sensors.
