Hydraulic-Based Rotational System For Solar Concentrators That Resists High Wind Loads Without A Mechanical Lock
US Patent:
2010004, Feb 25, 2010
Filed:
Aug 20, 2009
Appl. No.:
12/544910
Inventors:
Randall C. Gee - Arvada CO, US
Assignee:
SkyFuel, Inc. - Albuquerque NM
International Classification:
F24J 2/46, B21D 51/16
US Classification:
126571, 2989009
Abstract:
A rotational system is provided for controlling rotation of one or more solar collectors to track the movement of the sun, to automatically keep the collectors locked in stow position during high wind conditions, and advantageously also to prevent damage to the rotational system due to high pressures caused by high temperature conditions. The system utilizes a bi-directional hydraulic rotational actuator hydraulically connected to a control system. The actuator advantageously includes a system of helical gears and a piston, and the control system includes hydraulic lines equipped with check valves that prevent circulation of hydraulic fluid through the hydraulic lines and the actuator when backpressure is exerted in one of the hydraulic lines as a result of high wind force on the collectors. In addition, the control system advantageously comprises a pressure-relief system to prevent damage to the actuator during high temperature conditions. A single actuator can be used to operate up to sixteen or more large solar collectors.
Space Frame Connector
US Patent:
2010000, Jan 14, 2010
Filed:

Assignee:
SkyFuel, Inc. - Albuquerque NM
International Classification:
E04H 12/22, E04H 12/00
US Classification:
526551, 527452
Abstract:
A space frame connector is provided for attaching an oblique strut tube to an axial chord of a space frame. The space frame connector includes a collar adapted to fit over an axial chord. The collar is equipped with one or more attachment flanges. The space frame connector also includes a strut tube having an extrusion flange formed in at least one of its ends. The extrusion flange is made up of two parallel leaves that define a slot between them. The slot is sized and shaped to fit over an attachment flange on the collar that is positioned over the axial chord. The extrusion flange can be formed using simple press and punch tools. Space frames used to support solar energy collector arrays can be assembled in the field, including formation of the extrusion flanges on the oblique strut tubes, or multiple strut tubes can be attached to axial chords and compactly packed and transported to the field for use in constructing space frames, for example for supporting large parabolic trough solar collectors.

Abstract:
Provided herein are solar collectors having reflective sheets which are slidably insertable and/or removable for quick installation, construction, removal, repair, and/or replacement. Also provided are solar collectors having reflective sheets under tension. Further provided are methods for constructing solar collectors. In another aspect, provided herein are guide rails for guiding and/or retaining slidably removable reflective sheets and holding the reflective sheets in a prescribed shape.
