The single axis type is used to rotate the solar panels to each other in response to a change in the azimuth angle of the sun. Since the altitude is not tracked, there is only one rotating axis, which is simple and easy to install by forming a colony. In comparison, the operation is relatively easy, but the energy collected is low.

On the other hand, the biaxial type is designed to rotate the solar panels in the east and west to track the altitude of the sun in response to changes in the azimuth and altitude of the sun and to track the altitude of the sun in the vertical direction. And it is difficult to operate.

The panel rotation shaft 25 is preferably configured to be rotatable in a state supported by the fixing unit 15 on the upper portion of the support (10). The panel rotating shaft 25 may be integrally formed with the solar cell panel 20, and as illustrated in the drawing, the panel rotating shaft 25 may be separately configured such that the solar cell panel 20 and the guide member 40 are formed. It is also possible to configure the combination to rotate together.

3, the panel rotation shaft 25 may be configured to have a dual shaft structure. The panel rotation shaft 25 may include a support rod 26 installed therein and a rotation rod 27 installed outside thereof. In this case, the support rod 26 is installed in a state fixed to the upper end of the support 10 through the fixing portion 15, the rotary rod 27 is rotated in a state fitted to the outside of the support rod 26. Of course, it is preferable that a bearing 16 or a bushing is installed between the support rod 26 and the rotary rod 27 so that the rotary rod 27 can rotate smoothly.

Next, the solar cell panel 20 is basically configured to convert solar energy by installing solar cells to convert light energy into electrical energy, and as shown in FIG. 1, a plurality of solar cells are disposed on the top of the panel. It is configured to absorb sunlight. Here, the solar cell panel 20 is not limited to the flat plate structure illustrated in the drawings, and may also include a solar collection structure having a light collecting structure using a reflecting plate or the like depending on the embodiment conditions.

Next, as shown in FIG. 2, when the solar cell panels 20 are disposed on both sides of the driving mechanism 50, two driving bars 30 are provided in the center support 10.

One drive bar 30A is directly driven by the drive mechanism 50, and the other drive bar 30B is connected to one drive bar 30A and the bar rotation shaft 32 with reference to FIG. 3. And to rotate. Of course, the other drive bar 30B may also be directly connected to and driven by the drive mechanism 50.

The drive bar 30 is formed of a long rod-like structure, one end is coupled to the bar rotation shaft 32 installed to penetrate the support 10 is configured to rotate at one point, the other end is The guide member 40 is connected to the relative movement in a sliding manner.

The portion where the drive bar 30 and the guide member 40 are coupled to allow relative movement is connected to the drive bar 30 to allow linear movement along the guide member 40.

With this structure, when the drive bar 30 is rotated by the drive mechanism 50, one end of the drive bar 30 is rotated about the bar rotation axis 32, the other end is The guide member 40 can be rotated about the panel rotation shaft 25 while the guide member 40 is moved along the side in a sliding manner.

Next, the guide member 40 is provided with a guide rail 45 on one side or both sides thereof so that the other end of the driving bar 30 is coupled to move linearly.

In the drawing of this embodiment, the guide rail 45 is configured on both sides of the guide member 40 to show the configuration in which the drive bar 30 is coupled. In addition, the guide rail 45 is formed in an elongated groove structure, the drive bar 30 is inserted into the guide rail 45 shows a configuration in which the roller 35 is installed so that the rolling motion along the guide rail.
