| 摘要 |
The invention relates to a tracking support system for solar modules (4), especially photovoltaic modules, comprising module support frames (2) which are rotatably mounted between two support legs (1). The module support frame (2) is coupled, via a swivel bar (8), to a linear antifriction bearing (9) that is arranged on a support leg (1) and to an electric cylinder (10) for performing swiveling movements. The module support frame (2) is provided with spaced-apart bearings (11) for the rotational shafts (12) of the module supports (3), said rotational shafts extending perpendicular to the pivot axis (7) of the module support frame (2). The outer dimensions of the module support and module are designed such that the module support and the module can be swiveled across the plane defined by the module support frame (2). Each rotational shaft (12) of the module supports (3) is provided with one swiveling lever (13) which is connected to a split push rod (16) via a joint (17) that connects adjacent sections of the push rod. A push rod (16) can be displaced by means of an electric cylinder (15) that is placed on the module support frame (2). The movement of the electric cylinders (10, 15) depends on the position of the sun or is controlled as a function of time. Also disclosed is a method for controlling a tracking support system for solar modules. |
