ソーラー・収集および追跡機構
Document Type and Number:
Japanese Patent JP5311697
Kind Code:
B2
Abstract:
A solar energy collector and tracker has at least one north-south oriented torsion tube supporting an array of flat rectangular solar panels. At least one pier, supported in the earth, has pivot member in which the torsion tube is journalled. A linear actuator has a body portion mounted on a footing separate from the pier footing and supported in the earth at a distance spaced from pier, and has a rod coupled to a torque arm on the torsion tube. The actuator can be horizontally or vertically oriented. The torsion tube is generally square cross section. The torsion tube may be formed of two or more sections joined end to end. In such case, one of the sections may have one end swaged to fit tightly into the end of a next successive section to form a tight, secure coupling between sections. The pivot member can have four plastic resin inserts within a cylindrical journal on respective sides of the square torsion tube. The horizontal driver can be used to drive multiple rows of solar panels, with a linkage mechanism connecting the torque arms of the multiple rows. The linkage mechanism can include a series of rigid link members articulated to one another, permitting use on uneven terrain. Wires can be concealed within the tubular members.
