The intermittent rotation of the operating motor (M) is operated by the program set in the timer (T) and the control box (C), and the operating motor (T) rotates according to the distance of the sun, so that the solar module 80 ) Is always set to be located close to the sun and on a vertical line.

When the sun sets, the operating motor (M) continuously operates in reverse rotation and returns to the direction in which the sun rises in the morning, waiting for operation the next day.

The height adjustment of the lifting platform 62 constituting the rear support 60 may be set manually, but in the present invention, for convenience of operation, the lifting screw rod 90 was simply rotated to adjust the height.

That is, the connection section 91 is double-installed on the fixing table 61, the screw tube body 92 is fixedly installed in the center of the connection section 91, and the lifting screw rod 90 is screwed to the screw tube body 92. Combine.

At the same time, the rear support 60 is installed inclined in the direction of the rotation axis of the rotating shaft bar 10, so that there is no obstacle to the height adjustment of the lifting platform 62.

In configuring the solar module holder 10 of the present invention, it may be operated by interlocking with another adjacent solar module holder 10 using one operating motor (M).

That is, as shown in FIG. 8, an interlocking pulley (75) is additionally installed at the tip of the rotating shaft bar (70), and then, an interlocking pulley (75) and a belt (73) installed on another solar module holder (10) located on the side are used.

At this time, there is no need to install a separate operating motor (M) on the solar module holder 10 located at the side or rear.

Adjustment of the inclination angle of the solar module 80 of the solar module holder 10 configured as described above is performed as follows.

First, the altitude of the sun changes according to the season. Since the high altitude of the sun is low in winter and is maintained high in the summer, it is necessary to optimally adjust the vertical inclination angle of the solar module 80 according to the altitude of the sun.

Therefore, the angle of the solar module 80 is adjusted in consideration of the altitude of the sun according to the season, and it is manually operated.

That is, when the handle 95 of the lifting screw rod 90 installed on the rear support 60 is rotated, the lifting screw rod 90 coupled to the screw tube body 92 rises or descends.

Therefore, in the case of the winter season, by rotating the lifting screw rod 90, the lifting rod 62 inserted in the fixing rod 61 rises, so that the rear end of the rotary shaft rod 70 rises, thereby increasing the inclination angle of the solar module 80, It is adjusted so that it has almost vertical contact with the low-altitude sun in winter.

In addition, in the summer season, by rotating the lifting screw rod 90 so that the lifting platform 62 inserted in the fixing table 61 descends, the inclination angle of the solar module 80 decreases as the rear end of the rotation shaft rod 70 descends. , Adjust so that you can get almost vertical contact with the high-altitude sun in summer.

When adjusting the inclination angle of the photovoltaic module 80 as described above, the center of the rotation axis of the rotation shaft bar 70 moves up and down while making a circular motion around the vertical rotation body 32 installed on the bracket 31 of the front support 30. Therefore, when the rotary shaft rod 70 is raised and lowered around the vertical rotary body 32, the distance may vary depending on the position.

Therefore, it is installed on the rear support (60), and after loosening the fastening bolt (64) of the bracket (63) supporting the rear end of the rotating shaft (70), the bracket (63) is moved along the long hole (65) a certain distance.

As described above, the inclination angle of the solar module 80 is optimally adjusted and used according to the season in which the altitude of the sun varies, thereby increasing the efficiency of converting solar energy into electric energy.

In addition, adjustment according to the position of the sun, which changes by time zone from sunrise to sunset, is made by an operation motor (M) that intermittently rotates by a program set in the timer (T) and the control box (C), and the operation motor ( The operating time of M) is also set differently for each season and used.

The initial setting is to set the solar module 80 in the optimal condition in the direction of the sunrise angle, then divide it into several steps until sunset time, and operate the operating motor (M) intermittently step by step to rotate the rotary shaft bar (70). By doing so, since the solar module 80 moves along with the sun, the solar module 80 always faces the sun in optimal conditions.

After sunset, the operating motor M rotates in reverse to restore the solar module 80 to its initial state, and waits for operation the next day.

In addition, when adjusting the angle of the solar module 80 using a single actuating motor (M), as shown in Figs. 8 and 9, the adjacent solar module holder 10 is connected to an interlocking pulley 75, 77 and a belt 76 ( 78), it is possible to reduce the cost according to the equipment and facilities, as well as save energy by driving the operating motor (M).

As described above, in the case of the solar module holder to be provided by the present invention, the vertical angle of the solar module is adjusted according to the altitude of the sun that changes according to the season, and at the same time, the solar light is adjusted according to the position of the sun that changes according to time.
