The rotating plate 39 and the top cover 40 are fixed to the upper rotating shaft 11 of the rotating body 8 by fastening bolts 41 (see FIGS. 3, 4, and 5), and fixedly installed. A nut hole 42 is formed on the upper rotating shaft 11, and through holes 43 and 43 a are formed in the rotating plate 39 and the top cover 40, and the through holes 43 are formed by the fastening bolts 41. Through 43a is fixed to the nut hole 42.

The rotating plate 39 is formed on the rail 28 of the support plate 21 by forming the fixing piece 44 in various places of the periphery and installing the roller 45 on the fixing piece 44. To flow from side to side.

The solar panel S combined with the automatic solar tracking sensor Q is coupled to the upper side of the top cover 40 by the height adjustment frame 46 and the support bar 47.

In addition, a circuit board (PCB) 48 having a circuit device (not shown) is installed at the bottom of the upper bottom surface 3.

The configuration of the present invention as described above is rotated by the drive of the drive motor 5, the coil spring 37, the rotating plate 39 and the top cover 40 is rotated according to the rotation of these components The altitude angle adjusting frame 46 and the support bar 47 and the solar panel S coupled to the upper side of the top cover 40 rotate.

The drive device of the present invention is used fixedly installed on the support (G).

Referring to the operation of the present invention configured as described above are as follows.

The sun rises daily from east to west as shown in FIG. 11 (which corresponds to the northern hemisphere of the earth, and in the southern hemisphere the sun rises from the west to the east), thus shifting the sun's position as described above Azimuth angle change) to accurately detect and track the solar panel (S) at all times will be able to increase the power generation efficiency of the solar panel (S).

In order to increase the power generation efficiency of such a solar panel (S) by rotating the solar panel (S) in accordance with the movement of the sun by the drive device of the present invention according to the change in the azimuth angle of the sun to always face the sun. will be.

When the sun rises and moves along the orbit of the sun, when the sunlight is detected by the automatic solar tracking sensor Q, the driving motor 5 is driven by a command of a circuit device (not shown) configured on the circuit board 48. .

When the driving motor 5 is driven, the driving force drives the driving gear 7 via the reduction gear 4, and as the driving gear 7 is driven, the driving force is the rotational gear 20 and the worm shaft 18. ), The worm 19 and the worm gear 13 are sequentially transmitted in this case, in this case, the rotating body 8, the rotating plate 39, the top cover 40 is rotated and the top cover 40 is rotated for altitude angle adjustment The frame 46, the support bar 47, and the solar panel S rotate.

Therefore, the solar panel S is always facing the sun as the sun moves.

The driving device of the present invention is driven until the sun rises and the sunset is made, the driving device that was driven along the sun stops driving.

That is, when the sunset of the sun is made, the automatic tracking sensor (Q) detects the sunset and stops the driving of the driving motor 5 through a circuit device (not shown). In the case of an unexpected issue such as a mistake, the driving motor 5 may not stop driving and may continue to operate even after sunset.

In this case, the rotor 8 rotates together with the solar panel S by driving the driving motor 5 according to the movement of the sun for safe driving, and the rotor 8 rotates. The first and second spring bars 35 and 36 of the coil spring 37 also rotate together (see FIG. 9), and when the sun sets, the second spring bar (as shown in FIG. 9C) 36 touches the upper portion of the lever piece 29.

In this case, the lever piece 29 rotates the pivot pin 30 as a starting point, and the lower side stops the driving of the driving motor 5 being driven by the first latch lever 33 of the first limit switch 31. At the same time, the drive motor 5 is again driven.

At this time, the drive gear 7, the rotation gear 20, the worm 19, the worm gear 13 and the rotating body 8, the coil spring 37, the rotating plate 39, the top cover 40 and the forward rotation The altitude angle adjustment frame 46, the support bar 47, and the solar panel S are rotated back to the initial state, and the first spring bar 35 is the lever piece 29 as shown in FIG. 9A. Touch the upper side of the

At this time, the lever piece 29 rotates the pivot pin 30 from the starting point, and the lower side stops the driving of the driving motor 5 being driven by the second latch lever 34 of the second limit switch 32. The solar panel S is returned to its initial position to prepare for the next day.

On the other hand, the idling holes 14 and 14a are formed at both sides of the metal worm gear band 15 coupled to the rotating body 8 so that the rotation of the worm 19 is over driven by the driving motor 5. Even if the worm (19) is inserted into the idle hole (14) (14a), the idling is made, so that the rotation by blocking the transmission of the rotational force of the rotating body (8) and all the components connected thereto. It can be stopped. Therefore, the safety can be further secured.

And since the solar panel (S) is exposed to the wind in the open air as it is, when the typhoon or strong wind blows the wind as it is, in this case by the strong wind and the solar panel (solar panel) (S) and There is a risk of breakage of the organically coupled components.

In order to solve this problem, in the present invention, as shown in FIGS. 5 and 10, the roller 45 of the rotating plate 39 is mounted on the rail 28 of the support plate 21, and thus flows from side to side along the rail 28. Will be done.

Therefore, even when a typhoon or strong wind blows, the flow is smoothly, and the components organically combined with the solar panel S can be safely protected from breakage.

In addition, since the rotating plate 39 is supported at various places by the plurality of rollers 45 on the rail 28 of the support plate 21, it is possible to withstand large loads so that a solar panel having a larger capacity can be mounted. It can be.

As described above, the present invention enables the solar panel S to be driven to face the sun according to the orbit of the sun (ie, the change in the azimuth angle of the sun) so that the solar panel S can be received more effectively. It will increase the power generation efficiency of), and also ensure the safety of the driving device and improve the accuracy of tracking according to the change of azimuth angle of the sun by precise driving.

In addition, the driving device of the present invention can install a larger capacity solar panel to maximize the power generation efficiency.
