The solar panel (S) is rotated according to the movement of the sun by the automatic tracking driving device (H) as described above so that it can always face the sun.

When the sun rises and moves along the orbit of the sun, the solar light automatic tracking sensor (Q) (see FIGS. 1 and 14 to 15) detects sunlight and a circuit device configured on a circuit board (not shown) The driving motor 14 is driven by a command of (not shown).

When the driving motor 14 is driven, the driving force drives the driving gear 16 via the reduction gear 13 , and as the driving gear 16 is driven, the driving force is applied to the rotation gear 12 and the worm shaft 10 . ), the worm 11 and the worm gear C are sequentially transmitted.

Accordingly, the solar panel S always faces the sun according to the movement of the sun.

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

That is, when the sunset of the sun is made, the automatic solar tracking sensor Q detects that the sunset has been made and stops the driving of the driving motor 14 through a circuit device (not shown), but When an unexpected event such as a misunderstanding occurs, the driving motor 14 does not stop driving and continues to operate even after sunset may occur.

In this case, for safe operation, the first limit switch 23 is in touch with the first stopper 25 as shown in FIG. ], when the sunrise is made, the solar automatic tracking sensor (Q) detects that the sunrise has been made and starts driving the driving motor 14 through a circuit device (not shown).

The automatic tracking driving device (H) of the present invention as described above receives sunlight more effectively by driving the solar panel (S) to face the sun according to the orbit of the sun (that is, the change in the azimuth of the sun). It is possible to increase the power generation efficiency of the solar panel (S), and also to secure the safety according to the driving of the driving device, and to increase the accuracy of tracking according to the change of the azimuth of the sun by precise driving.

In addition, since it is coupled to the shaft and driven around the shaft, it can withstand strong typhoons or strong winds, and a larger-capacity solar panel can be installed to maximize power generation efficiency.

The solar automatic tracking sensor Q is installed with a circuit board (PCB) 51 built-in inside the body 50 configured as a case type as in FIGS. 8 to 13 , and is installed on the upper side of the body 50 . The sensor mounting unit (U) and the transparent body type lid 52 are combined.

The sensor mounting unit (U) is composed of a support frame body 54 and a frame body 55 for mounting the detection sensor, and the support frame body 54 is rear end mounted on which the bottom surface 56 and the sunset sensor 57 are mounted. The face 58 is configured vertically, and the frame 55 for mounting the detection sensor is mounted on the left side on both sides of which the eastern orientation sensor 59 is mounted and the right side on which the western orientation sensor 61 is mounted. It is constituted by forming a surface 62 .

The left mounting surface 60 and the right mounting surface 62 are inclined in a direction extending from the center of the sensor mounting frame 55 to both sides.

The sunset sensor 57, the east orientation sensor 59, and the west orientation sensor 61 are implemented as ordinary solar cells that output a voltage proportional to the received sun.

A coupling hole 56a is formed in the front portion of the bottom surface 56 of the support frame 54 as a coupling means between the support frame 54 and the detection sensor mounting frame 55, and both sides of the rear end mounting surface 58 A fastening groove 67 is formed in the part, and a coupling protrusion 68 is formed to protrude to the lower front of the frame for mounting the detection sensor 55 to be inserted and coupled to the coupling hole 56a, and the frame for mounting the detection sensor. Both ends of (55) are inserted and coupled to the fastening groove (67) (see FIG. 11).

The eastern orientation sensor 59 and the western orientation sensor 61 form a predetermined inclination angle θ (θ1) from the center of the frame 55 for mounting the detection sensor as a starting point as shown in FIG. 11, and these inclination angles θ and θ1 are the same, preferably each 45° to form 90°.

In addition, an O-ring groove 69 is formed in the lower portion of the transparent body-type lid 52 , an automatic pressure adjusting hole 70 is formed at one side of the O-ring groove 69 , and an O-ring having elasticity in the O-ring groove 69 . (71) is inserted and coupled.

A ventilation hole 72 is formed at the upper end of the transparent body type lid 52 and a sealing washer 73 for opening and closing the ventilation hole 72 and an adjustment bolt 74 are combined.

The upper and lower portions where the main body 50 and the transparent lid 52 are coupled are sealed with packings 75 and 76, and the fastening bolts 77 are fastened for safety of coupling.

The solar automatic tracking sensor (Q) as above is used in combination with the solar panel (S) constituting the solar generator.

Therefore, the solar panel (S) is used to increase the power generation efficiency by following the movement of the sun and always facing it.

As shown in FIG. 13 , the sun rises in the east and sets in the west every day, and the altitude of the sun is high in summer (summer) and low in winter (winter solstice).

Therefore, if the solar panel S is tracked by accurately detecting the positional movement of the sun, the power generation efficiency of the solar panel S can be increased.

When the sun rises, as shown in Fig. 13(a), the western orientation sensor 61 receives a large amount of sunlight, and the eastern orientation sensor 59 receives a small amount of sunlight, and each western orientation sensor ( 61) and the orientation sensor 59 output a voltage corresponding to the amount of sunlight, and compare the amount of sunlight information with a circuit device (not shown) configured on the circuit board 51 .

The comparison result at this time shows that the amount of sunlight detected by the western orientation sensor 61 is greater than the amount of sunlight detected by the eastern orientation sensor 59, and in this case, a circuit device (not shown) configured on the circuit board 51 . The azimuth driving motor (not shown) is operated from east to west so that more sunlight can be irradiated to the east orientation sensor 59 by the control of the solar panel S so that the solar panel S moves to the west.

That is, when the sun is positioned at the exact center of the sensor mounting unit U as shown in FIG. 11, the amount of sunlight detected by the eastern orientation sensor 59 and the western orientation sensor 61 is the same, and the sun ), the amount of sunlight reflected on the azimuth sensor 61 is greater than the amount of sunlight irradiated on the eastern orientation sensor 59, and accordingly, the solar panel S is moved to the west and the azimuth sensor ( 61) and the amount of sunlight detected by the azimuth sensor 59 are adjusted to be the same.

In this way, the sun is continuously tracked according to the movement of the sun until it sets to the west, whereby the solar panel S always faces the sun accurately.

On the other hand, as shown in FIG. 13(c), when the sun sets completely to the west and the sunset is made, it is detected that the sunlight illuminance is below a certain value (0.5KLux) by the sunset sensor 57, and the sunset detection information is displayed on the circuit board ( 51) is input to the circuit device (not shown), and after determining the sunset state in the circuit device (not shown), the azimuth driving motor (not shown) is returned to the initial position as shown in FIG. 13(d) to prepare for the next day. .

And, in the present invention, it is possible when the traceable solar illuminance is 30KLux or more, and when the sunlight is not detected because the weather is cloudy or foggy, the solar tracking operation is not performed.

On the other hand, when sunlight is received, the inside of the transparent body type lid 52 rises to a maximum of 85 ℃ depending on the region, and then drops to a minimum of -35 ℃ after sunset. will rise

Due to this, the function of the sunset sensor 57, the east orientation sensor 59, and the west orientation sensor 61 made of a solar cell is deteriorated due to the contraction and relaxation caused by the temperature difference and the pressure difference, and there is a problem in that the efficient reception of sunlight is reduced.

In addition, there is a problem in that a gap is formed in the coupling portion of the body 50 and the transparent body type lid 52 , moisture or dust flows in, and in particular, moisture occurs on the inner wall of the transparent body type lid 52 . These problems are solved in the present invention. was completely resolved.

That is, as shown in FIG. 10, when high temperature and high pressure of a certain degree or more is generated by the reception of sunlight inside the transparent body type lid 52, it is discharged to the outside through the automatic pressure control hole 70 formed in the O-ring groove 69. In this case, as the flexible O-ring 71 inserted and coupled to the O-ring groove 69 is relaxed, the automatic pressure adjusting hole 70 is automatically opened, thereby appropriately adjusting the temperature and pressure inside the transparent body type lid 52 . will do

When the temperature and pressure are lower than a certain level inside the transparent body-type lid 52 again, the flexible O-ring 71 is contracted to seal the automatic pressure adjusting hole 70 .

On the other hand, when assembling the main body 50 and the transparent lid 52, the packings 75 and 76 are combined, so that the inside of the transparent lid 52 is filled with air and cannot escape to the outside, so assembly is easy. It is not easy. In this case, when the vent hole 72 is opened and assembled using the adjustment bolt 74 and the sealing washer 73 configured at the upper end of the transparent body type lid 52, the vent hole 72 is As the air escapes, the assembly can be completed easily.

In addition, after the assembly is completed, purified air is injected through the vent hole 72 and sealed again.

Therefore, it is possible to protect the performance of the sunset sensor 57, the east orientation sensor 59, and the west orientation sensor 61 by injecting the purified air and extend the lifespan.

And in an emergency, such as when moisture is generated on the inner wall of the transparent body type lid 52 due to a severe temperature difference during use, the ventilation hole 72 is opened using the control bolt 74 and the sealing washer 73, and then When heat is applied to the transparent body type lid 52 , moisture can be quickly and easily removed.
