Description

Solar photovoltaic device installed in agriculture and livestock area}

The present invention relates to a photovoltaic device, and more particularly, it is installed in an agricultural and livestock farming area, such as paddy fields, fields, or barns, and is based on an agricultural and livestock farming area that can increase income by performing photovoltaic power generation while farming or raising livestock. It relates to a photovoltaic device.

In general, a solar cell is a cell that generates electricity by using sunlight. In other words, solar power is used to generate electricity, and the electricity is used to operate various machines and apparatuses.

Photovoltaic power generation is a technology that allows you to convert the sunlight without any pollution into electricity directly. Power generation using solar power uses infinite clean energy. It requires no additional energy or driving source, and the construction of the system is simple from small to large. It has the advantage that it is not affected by the installation limitations due to environmental problems, while the amount of power generation depends on the solar radiation time, and a large number of solar modules are required to obtain large power, which is expensive compared to commercial power and is used daily. There is a disadvantage that direct current is obtained first rather than alternating current.

In recent years, large-scale photovoltaic panels are installed on farmland, plastic house, livestock house, or fruit farm to cultivate crops, and produce electricity by using electricity or by buying and selling electricity. Are increasing.

Such solar panels can use the power generated directly during the day when sunlight can be received, but since the power is not produced at night, to use the power continuously, a circuit is formed to charge the storage battery during the day when the power is produced. It should be kept and used.

In reality, however, the sun moves from east to west during the day, and the earth revolves around the sun with its 23.5 ° tilted, causing seasonal variations in the latitude of the earth, changing the sun's altitude for each season.

For example, if the current latitude is 35 ° north latitude, the sun's altitude for each season is about 35 ° in spring and autumn, about 12 ° in winter, and 58 ° in summer. The altitude will change to an extent.

On the other hand, the power generation efficiency by the solar panel may vary depending on a number of factors, in order to obtain the optimal power generation efficiency it is necessary to maximize the energy collected. For this purpose, it is required that the angle between the photovoltaic panel and the photovoltaic line is perpendicular.

Therefore, as described above, the conventional fixed solar panel structure has a problem that the angle between the solar light and the solar panel is not perpendicular to each other except for a specific season, so that the maximum output is not obtained and the economic effect is inferior. It would be necessary to have a tracking device that is driven so that the panel tracks along the path of the sun.

A support hole 721 is formed in the inclination adjustment rod bracket 720 so that the end of the inclination adjustment rod 200 penetrates and is supported. The bearing b is inserted between the inclination adjusting rod 200 and the support hole 721 to rotatably support the inclination adjusting rod 200.

At this time, the inclination adjusting rod 200 is made of a rectangular beam as a whole, the portion inserted into the support hole 721 is made of a circular rod shape.

In addition, a connection member bracket 730 is formed on the outer circumference of the joint 700.

The connecting member bracket 730 is formed in the shape of a plate member protruding from the outer periphery of the joint 700 or coupled by welding or the like.

One end of the connection member 300 may be fixedly coupled or rotatably coupled to the connection member bracket 730.

Here, the other end of the connection member 300 is coupled to the inclination adjustment rod bracket 720 of the joint bound to the other strut 100. To this end, the other end of the connection member 300 is inserted between the inclination adjustment rod bracket 720 and may be coupled by a coupling pin 740.

On the other hand, when the binding piece 710 of the joint 700 is fastened, the joint 700 is in close contact with the support 100. As described above, since the support 100 is tapered, the joint 700 is No matter how large the load is, it does not slide downward along the surface of the support 100. That is, it can withstand the load received by the inclination adjustment rod 200 and the connection member 300 in a state caught on the support (100).

Next, the mount and the daily tracking unit will be described with reference to FIG. 3. Figure 3 is a front view showing the mounting and the daily tracking portion of the present invention shown in FIG.

The mount 400 is fixed to the inclination adjustment rod 200 as a frame that can be mounted directly to the solar panel is rotated together in accordance with the rotation of the inclination adjustment rod 200.

Specifically, the mounting bracket 400 is inclined to both sides of the rectangular rectangular frame frame 410 and the rectangular frame frame 410 is coupled to the inclined frame 420 and the lower portion of the inclined frame 420 to distribute the support force It is composed of a support member 430 rotatably coupled to the inclination adjustment rod 200.

At this time, the inclined frame 420 is coupled to the pair inclined and meet at the center of the square frame 410 is coupled to the support member 430.

On the other hand, the daily tracking unit 500 for rotating the mount 400 along the sun from east to west during the day is a rotary support 510, a rotating shaft 520, a rotating sprocket 530, a rotating chain 540 ), It may be configured to include a daily control motor (not shown).

The rotation support 510 is coupled to and fixed to the upper surface of the inclination adjustment rod 200 to support the rotation shaft.

A rotating shaft is rotatably inserted into the rotating support 510 and coupled to the supporting member of the mounting unit 400 at one end of the rotating shaft 520. Accordingly, the support member 430 may rotate in the rotation support 510 together with the rotation shaft.

And the other end of the rotary shaft 520 is coupled to the rotary sprocket 530. In addition, the rotating sprocket 530 is wound around the rotating chain 540, and interlocks with the rotating sprockets 530 'and 530' 'coupled to other rotating shafts.

At this time, two rotating sprockets 530 are coupled to the rotating shaft 520 in parallel so that one rotating sprocket 530 is interlocked with another rotating sprocket 530 'on the right side, and the other rotating sprocket 530 is It is interlocked with another rotating sprocket 530 '' on the left side.

In this manner, the plurality of daily tracking units 500 may be linked to each other to drive only one rotation shaft 520, thereby driving all the daily tracking units 500 simultaneously to track the sun. That is, the mount 400 is always perpendicular to the sun.

To this end, the daily control motor drives any one of the rotating shafts (520).

The daily control motor may be installed at any position although not shown. And by installing a reduction gear box (not shown) to properly control the speed can be rotated slowly so that the mount 400 is perpendicular to the sun during the day.

Next, the seasonal tracking unit will be described with reference to FIG. 4. 4 is a front view showing a seasonal tracking unit of the present invention shown in FIG.

The seasonal tracking unit 600 is configured to adjust the inclination of the mounting bracket 400 coupled to the inclination adjustment rod 200, the inclination sprocket 610, the inclination chain 620, the seasonal control motor It is configured by.

Since the sun changes seasonally in the south during the year, it is necessary to adjust the inclination of the mount 400 so that the mount 400 is vertically disposed at a different mid-sea height.

To this end, the inclined sprocket 610 is respectively coupled to the end of the inclined adjustment rod 200.

In addition, the inclined sprocket 610 is interlocked with each other by the inclined chain 620.

Therefore, when any one of the inclined sprocket 610 is driven to rotate all the inclination adjusting rod 200 can be rotated at the same time.

Although not illustrated, the seasonal control motor may be installed to drive any one of the inclination adjusting rods 200. Of course, a separate reduction gear box (not shown) may be further provided to control the inclination adjusting rod 200 to rotate periodically.

Alternatively, the handle may be attached to any one of the inclination adjusting rods 200 without using the seasonal control motor and may be manually rotated according to the season.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 5. Figure 5 is a perspective view showing a rural based solar power generation device according to another embodiment of the present invention.

In the present invention, the strut 100, the inclination adjusting rod 200 and the connecting member 300 is subjected to a really large load.

Specifically, the inclination adjustment rod 200 receives a very large load because a plurality of mounting base 400 and the daily tracking unit 500 is installed on the top. Due to such a large load, deflection occurs in the inclination adjustment rod 200, and the truss structure 810 may be further coupled to the lower portion of the inclination adjustment rod 200 to reinforce it.

At this time, the shape of the truss structure 810 may be any shape, but it is preferable to avoid too heavy material or weight because the inclination adjusting rod 200 is rotated.

In addition, a wire 820 connecting the post and the inclination adjustment bar 200 may be further provided to prevent sagging of the inclination adjustment rod 200.

The wire 820 may connect the upper ends of the both sides of the support 100 and both sides of the inclination adjustment rod 200 or connect the central portion where the sag occurs most in the inclination adjustment rod 200.

In addition, the upper end of the support 100 due to the wire 820 is subjected to the bending moment. As a result, bending may occur at the upper end of the support 100, and in order to reinforce it, it is preferable to further attach the reinforcement member 830 to the upper part of the support 100.

The reinforcing member 830 may be formed in a separate beam or tube or plate shape.

In order to attach the reinforcing member 830 to the support 100, a member such as the joint 700 may be additionally used.

Hereinafter, an operation process of the present invention will be described with reference to FIG. 6. 6 is an operational state diagram of the present invention.

First, the process of tracking the sun from the east side to the west side 400 during the day will be described. (See Figure 6 (a))

In the morning when the sun rises, the mounting unit 400 is located to face east, as the sun rises and the altitude increases, the daily control motor (not shown) rotates the rotating shaft 520 at a constant speed .

If the sun is located at the south mid- altitude in the afternoon, the mount 400 is horizontal and continues to rotate westward at sunset.

And after dark, the daily control motor is controlled to automatically rotate in reverse so that the mount 400 is returned to the east.

As described above, since the daily tracking unit 500 is interlocked, it is controlled to rotate at the same time by one daily control motor.

Next, the process of adjusting the inclination so that the mount 400 tracks along the southern height of the sun for one year will be described. (See Figure 6 (b))

The southern height of the sun changes with the seasons. In other words, the height of the south is the highest when not based on Korea, and the lowest when it is a winter solstice.

At the same time, the inclination adjusting rod 200 may be manually or automatically rotated to adjust the inclination of the mount 400 coupled to the inclination adjusting rod 200.

That is, since the height of the south of the sun is the lowest during the winter solstice, the inclination of the mount 400 becomes the largest so that the sun and the mount 400 are not perpendicular to each other.

From the winter solstice through the vernal equinox, the sun's height in the middle of the sun increases, so that the inclination of the mount 400 is reduced by rotating the inclination adjustment rod 200 in one direction.

And since the lower half of the sun is lowered toward the winter sol through the autumnal fall from the lower ground, the inclination of the mount 400 can be increased by rotating the inclination control rod 200 in the opposite direction.

Similarly, all seasonal tracking unit 600 is also interlocked, so if one drive the inclination adjustment rod 200, all inclination adjustment rod 200 can be inclined at the same time.

In this way, the mount 400 rotates along the east and west on a daily basis and at the same time seasonally inclined is adjusted so that it is always located vertically toward the sun, thereby maintaining the maximum power generation efficiency.

Although the exemplary embodiments of the present invention have been described above with reference to the drawings, those skilled in the art will be able to perform various applications and modifications within the scope of the present invention based on the above contents. Therefore, the scope of the present invention should not be limited to the embodiments described, but should be defined by the claims below and equivalents thereof.
