Abstract:

A three-column two-shaft-type solar tracking apparatus using a cross-shaped connection piece and a direct cylinder of the present invention is applied with a cross-shaped connection piece or a ball joint for detecting the azimuth and the altitude angle of the sun, so that a solar heat collection panel or a solar cell panel (101) constantly directly faces the sun for maximized efficiency, and applied with a fixed main column (105) and two movable auxiliary columns (106, 107) for establishing a structure having a total of three columns so as to be stable to the perpendicular load of the structure and to external force, thereby enabling a larger size and a larger capacity. Also, the present invention is a solar tracking apparatus, which can comprise a more stable three-column one-shaft type solar tracking apparatus having two fixed columns and one movable auxiliary column when some functions are reduced to have the one movable auxiliary column, can minimize damage to green space by not requiring facilities on the ground other than the three columns, and which can also allow flexible land usage. The three-column two-shaft-type solar tracking apparatus using the cross-shaped connection piece and the direct cylinder of the present invention is the solar tracking apparatus which is applied with the cross-shaped connection piece or the ball join for tracking the azimuth and the altitude angle of the sun, wherein the entire structure would be vulnerable to twisting with the main column (105), which is a fixed column, at the center when the cross-shaped connection piece is applied, due to the property of the cross-shaped connection piece having two free angles. Therefore, to eliminate the vulnerability, a locking function for locking relative movement to the cross-shaped connection piece is provided so that the entire structure has a strong body. The three-column two-shaft-type solar tracking apparatus using the cross-shaped connection piece and the direct cylinder of the present invention is the solar tracking apparatus characterized by being designed so as to only rotate for routine and repeated azimuth tracking while the altitude angle is fixed until an altitude change signal is generated from a random altitude angle, thereby significantly reducing the operation frequency of a driving portion so as to increase durability and simplicity of control of machinery. The three-column two-shaft-type solar tracking apparatus using the cross-shaped connection piece and the direct cylinder of the present invention is the solar tracking apparatus, which allows accommodation of electric and machine apparatuses for a power generation facility, in addition to housing and office spaces in which a person can stay, inside the main column (105), by achieving the large size and the large capacity.
