The support body 140a is coupled to both sides of the rotation body 141 so that the solar cell plate 110 is fixed.

The support 140a may be partially inserted into the rotation body 141 and extend to the outside of the rotation body 141. [

The outer circumferential surface of the supporter 140a may be formed of a cylindrical pipe and a part of the solar photovoltaic plate 110 may be fixedly coupled to the outer circumferential surface of the supporter 140a or the solar cell plate 110 may be tilted Can be combined.

The rotation body 141 may further include an extension shaft 140b extending to the upper portion of the support shaft 120 such that the rotation body 141 is separated from the upper portion of the support shaft 120. [

The extension shaft 140b is provided to eliminate interference between the support shaft 120 and the low power drive motor 142, which will be described later, when the rotation body 141 is rotated.

The length of the extension shaft 140b may be longer than the length of the low power drive motor 142 extending to the outside of the rotary body 141.

The extension shaft 140b may include a rotary gear shaft portion 140b-1 that is partially accommodated in the rotary body 141 and to which a rotary gear 143b to be described later is rotatably fixed.

The rotation gear shaft portion 140b-1 is formed in a cylindrical shape and a bearing (not shown) is coupled to the outer circumferential surface to minimize rotation interference of the rotation gear 143b.

The low power driving motor 142 is provided with a driving shaft 142a coupled to the outer surface of the rotating body 141 and extended to be inserted into the rotating body 141.

The low power driving motor 142 preferably uses a DC 24V low power motor. The organic coupling and the effect of the low power driving motor 142 will be described in the following description of the gear 143 to be described later.

The gear 143 is formed of a pair of shafts facing each other, and the drive shaft 142a is disposed on one side of the gear 143. The gear 143a is rotatably coupled to both sides of the rotation body 141 The rotary gear 141 is rotatably mounted on the other side of the transmission gear 143a and fixed to the lower portion of the inner side of the rotary body 141, (143b).

The transmission gear 143a includes a first gear portion 143a-1 that is rotated in different directions by the drive shaft 142a and is rotatably coupled to the outer circumferential surface of the drive shaft 142a, And a second gear portion 143a-2 rotatably coupled to the outer circumferential surface of the first gear portion 143a.

The drive shaft 142a, the first and second gear portions 143a-1 and 133a-2, and the rotary gear 143b are formed of worm gears.

The first gear portion 143a-1 is formed of a warm wheel, the second gear portion 143a-2 is a worm shaft, the rotation gear 143b is a worm wheel, .

The gear ratio between the driving shaft 142a and the first gear portion 143a-1 may be a ratio of 100: 1.

The gear ratio between the second gear portion 143a-2 and the rotary gear 143b may be a ratio of 100: 1.

The solar-cell-plate-position-adjusting device 140, which is provided as described above, calculates the position of the sun measured by the solar-light-position sensor (not shown) in the solar- The position value of the sun or the position values of any one of the sun positions in the same time zone collected in the previous day or in 10 years.

In the photovoltaic power generation system, the low-power drive motor 142 is driven so that the drive shaft 142a rotates a predetermined portion, and the first gear portion 143a-1 Is rotated.

As the first gear portion 143a-1 is rotated, the second gear portion 143a-2 is simultaneously operated and the second gear portion 143b is rotated, (Not shown).

Since the drive shaft 142a, the first and second gear portions 143a-1 and 133a-2 and the rotary gear 143b are formed of worm gears and have the effect of deceleration, .

For example, when the driving shaft 142a rotates 100 times, the first gear portion 143a-1 rotates once, and when the second gear portion 143a-2 rotates 100 times, The rotation gear 143b is rotated once.

Accordingly, when the drive shaft 142a rotates 10,000 times, the rotation gear 143b rotates once.

This is because even if the rotation amount of the drive shaft 142a is large, the rotation body 141 rotates within a range smaller than the rotation amount of the drive shaft 142a, so that a blind spot is formed at a position between the solar panel 110 and the sun There is an effect that can be eliminated.

Further, since the low-power driving motor 142 is mounted, the efficiency of using electric energy is also increased.

When a strong wind or other external force is generated in the solar cell plate 110, a deviation occurs between the first and second gear portions 143a-1 and 133a-2. In order to prevent this, The rotation gear 143b can be more stably fixed.

6 is a schematic use state diagram of the solar photovoltaic cell plate position adjusting device according to FIG.

The tilting unit 130 tilts the solar cell plate 110 according to the position of the solar cell plate 110, thereby more efficiently transmitting the sunlight to the solar cell plate 110, As shown in FIG.

The rotation unit 140 of the photovoltaic plate position adjusting device may use a gear ratio of the gear 143, the transmission gear 143a, and the rotary gear 143b to hold a strong wind or other external force Further, since the low-power driving motor 142 is used, the amount of power used to drive the rotation unit 140 can be reduced.

As described above, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims. And such modifications are within the scope of the present invention.
