Description

Solar photovoltaic device by tracking sun day and year}

The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device capable of tracking the sun by day and season and capable of generating power while tracking the sun for a day and a year.

In general, solar cells are cells that generate electricity using sunlight. That is, solar power is called as a method of generating electricity using sunlight and using this electricity to operate various machines and devices.

Solar power generation is a technology that allows unlimited, pollution-free sunlight to be directly converted into electricity, and solar power generation uses infinite clean energy. No additional energy or driving source is required, and system construction from small to large scale is simple. While it has the advantage of not being affected by installation restrictions due to environmental issues, the amount of power generation depends on the insolation time, and a lot of solar modules are required to obtain large power, and it is expensive compared to commercial power and is used on a daily basis. The disadvantage is that direct current is obtained first, not alternating current.

Recently, methods of generating electric power by installing large-scale solar panels in water such as sea or lake have been attempted.

These solar panels can use the power directly generated during the daytime when they can receive sunlight, but they cannot produce power at night, so to use power continuously, configure a circuit and charge the storage battery once during the day when power is produced. It should be kept and used.

However, in the conventional fixed solar panel structure, a solar panel equipped with a photovoltaic cell is installed and fixed at a certain angle toward the direct south direction or the direct north direction.

However, during the day the sun moves from east to west.

And because the earth orbits the sun with its axis tilted by 23.5°, seasons occur according to the latitude of the earth, and the altitude of the sun changes for each season.

For example, if the current latitude is 35° north latitude, looking at the altitude of the sun for each season, the sun's altitude is about 35° in spring or autumn, the sun's altitude is about 12° in winter, and 58° in summer. Until the altitude of the sun changes.

Meanwhile, the power generation efficiency of the solar panel may vary depending on various factors, but in order to obtain optimal power generation efficiency, it is necessary to maximize the concentrated energy. To this end, the angle between the solar panel and the sunlight is required to be perpendicular.

Therefore, as described above, the conventional fixed solar panel structure has a problem in that the angle between the sunlight and the solar panel is not perpendicular except for a specific season, so that the maximum output cannot be obtained and the economic effect is inferior.

Therefore, there is a need for a tracking device that is driven to track the solar panel according to the movement path of the sun on a daily and seasonal basis.

A rotation shaft to which the mount is coupled while being coupled, and a drive motor that is installed on the base plate and controls rotation so that the rotation shaft rotates according to the position of the sun for one day, so that the mount can be rotated to be perpendicular to the sun. .

At this time, a plurality of daily tracking units are continuously arranged in parallel on one side of the daily tracking unit, and a sprocket is coupled to one end of each rotation shaft, and each sprocket is mutually interlocked by a chain, so that all the daily tracking units are used with one drive motor. It can be controlled at the same time.

And the season tracking unit, the second support means, a pair of adjacent to the vertical plate and rotatably coupled to the lower link and the lower end are rotatably coupled to the upper end of the lower link by a hinge pin, and the upper end is the Consisting of an upper link rotatably coupled to the rotating shaft, an inclination adjustment rod having a male thread on one side penetrates the hinge pin at the same time, but a female thread is formed in any one of the hinge pins, so that the inclination adjustment rod is screwed together Thus, it is possible to adjust the inclination by rotating the inclination control rod to raise and lower one end of the mounting.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

For reference, the description with reference to the drawings is for easier understanding of the present invention, and the scope of the present invention is not limited thereto. Further, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, a detailed description will be omitted.

1 is a perspective view showing the overall structure of a photovoltaic device capable of tracking daily and seasonal solar according to an embodiment of the present invention.

The present invention largely supports the frame portion 100, the mounting plate 200 disposed on the upper side of the frame portion 100, and is installed on the frame portion 100 to support the mounting plate 200 A daily tracking unit 300 that rotates to follow the position of the sun during the day, and a seasonal tracking unit installed in the frame unit 100 to control the inclination angle so that the mounting base 200 follows the southern altitude of the sun that changes according to the season It may be configured to include the unit 400.

First, the frame unit 100 and the mounting table 200 will be described.

The frame unit 100 may include a horizontal plate 110 and a vertical plate 120.

The horizontal plate 110 has a flat plate shape and is disposed horizontally. And vertical plates 120 are formed vertically on both sides of the horizontal plate 110. Accordingly, the frame portion 100 may have a shape such as'┗┛' in cross section.

A mounting table 200 for mounting a solar panel is mounted on the upper side of the frame unit 100.

The mounting table 200 may include a rectangular frame member 210 and a support member 220 coupled to both sides of the rectangular frame member 210.

One of the support members 220 is a relatively long first support member 221, the other is a second support member 222 having a relatively short length, and is coupled to the vertical plate 120, respectively.

At this time, the first support member 221 may be rotated by being coupled to the daily tracking unit 300 provided on any one of the vertical plates 120, and the second support member 222 is the vertical plate ( 120) is coupled to the seasonal tracking unit 400 provided in the other one.

Next, a daily tracking unit will be described with reference to FIGS. 2 and 3 together. 2 is a front view showing the detailed structure of the daily tracking unit of the present invention shown in FIG. 1, and FIG. 3 is a front view showing the detailed structure of the seasonal tracking unit of the present invention shown in FIG.

The daily tracking unit 300 may include a first support means 310, a second support means 320, a rotation shaft 330, and a drive motor 340.

The first support means 310 is a configuration for rotating while supporting one side of the mounting table 200. The lower part is coupled to the vertical plate 120 on one side as a plate shape, and the rotation shaft 330 is rotated at the upper part. It can be combined as much as possible.

Preferably, as shown, a fixing plate 311 attached to the vertical plate 120 and a rotating plate 312 hinge-coupled to an upper portion of the fixing plate 311 and rotatably coupled to the rotation shaft 330 The folding structure made of is good.

This will be described later, but because the inclination of the rotating shaft 330 coupled to the rotating plate 312 is changed, the inclination of the rotating plate 312 is changed in response thereto.

The second support means 320 is a configuration for rotating while supporting the other side of the mounting table 200, and the lower portion is coupled to the vertical plate 120 on the other side, and the rotation shaft 330 is rotatably coupled to the upper portion. Can be.

However, as will be described later, in the present invention, the second support means 320 supports the mount 200, but has a structure in which the height of the mount 200 is adjusted so as to rise or fall.

That is, as shown, the second support means 320 may include a lower link 321 and an upper link 321.

The lower link 321 may be formed in a bar or beam shape, and a pair is provided, and each lower end is rotatably coupled to the vertical plate 120. In this case, the lower ends of the lower link 321 may be disposed adjacent to each other.

And the upper link 321 may also be formed in a bar or beam shape, and a pair is provided, and each lower end is rotatable by a hinge pin 323 at the upper end of the lower link 321 Are combined.

In addition, upper ends of the upper links 321 are arranged to overlap each other, and the rotation shaft 330 is rotatably coupled to the overlapped portion.

Therefore, when the pair of lower links 321 is opened, the upper link 321 is also opened and the height of the rotation shaft 330 is lowered, and when the lower link 321 is narrowed, the upper link 321 is also It is operated so that the height of the rotation shaft 330 increases while being narrowed. That is, it works like a hydraulic jack.

Meanwhile, the rotation shaft 330 is vertically disposed between the vertical plates 120 facing each other, and both ends are rotatably coupled to and supported by the first support means 310 and the second support means 320, respectively. The mounting base 200 is coupled and fixed to both sides of the rotation shaft 330 so that the mounting base 200 may rotate together with the rotation of the rotation shaft 330.

The driving motor 340 is installed on the horizontal plate 110 and the driving shaft of the driving motor 340 is interlocked with the rotation shaft 330 to rotate the rotation shaft 330.

Of course, it is natural that a gearbox 370 is provided between the drive shaft of the drive motor 340 and the rotation shaft 330 to transmit power such as deceleration.

Accordingly, the drive motor 340 controls the rotation of the rotation shaft 330 so that the mounting table 200 may slowly rotate so as to be perpendicular to the sun for one day.

However, in general, solar power generation increases the amount of power generated by installing numerous solar panels. Therefore, although the size of the mount 200 may be increased, it is reasonable to have a plurality of mounts, and the drive motor does not need to be installed for each mount.

Instead, it may be configured so that the power supplied from one of the driving motors 340 drives all of the plurality of daily tracking units 300.

That is, this is possible by allowing each of the daily tracking units 300 to interlock, specifically, a plurality of daily tracking units 300 are arranged in succession, but arranged in parallel at regular intervals.

In addition, sprockets 350 are respectively coupled to one end of the rotation shaft 330 included in each daily tracking unit 300, and the sprockets 350 are interlocked with each other by a chain. For example, as shown, two sprockets 350 are coupled to one rotation shaft 330, and any one sprocket 350 is a sprocket 350 and a chain 360 of one rotation shaft 330. It is connected and the other sprocket 350 may be connected to the sprocket 350 of the other side rotation shaft 330 by a chain.

Therefore, when the rotation shaft 330 of any one daily tracking unit 300 directly linked to the drive motor 340 rotates, the rotation axis of the other daily tracking unit 300 by the sprocket 350 and the chain 360 330 can also rotate together. That is, all mounts 200 can simultaneously track the sun during the day.

Next, a seasonal tracking unit will be described with reference to FIGS. 3 and 4. 4 is a plan view of a seasonal tracking unit of the present invention shown in FIG. 3.

The seasonal tracking unit 400 is provided with the second support means 320 and can adjust the inclination of the mounting table 200 by raising and lowering the mount 200 coupled to the second support means 320. It can be configured.

That is, since the sun changes in namjung altitude for each season for one year, the inclination of the mount 200 must be adjusted so that it is vertically disposed at different namjung altitudes for each season.

To this end, the seasonal tracking unit 400 may include a second support means 320 and a hinge pin 323, and may be configured as an inclination adjustment rod 410.

Since the second support means 320 and the hinge pin 323 are the same as described above, detailed descriptions are omitted.

The inclination adjustment rod 410 is formed in a rod shape and is inserted so as to penetrate the hinge pin 323 facing each other at the same time.

At this time, a female thread is formed on the inner circumferential surface of any one of the hinge pins 323.

In addition, a male thread 411 is formed on one side of the inclination adjustment rod 410 and is screwed with the female thread 411.

Therefore, when the inclination adjustment rod 410 is rotated, the hinge pin 323 on which the female thread () is formed moves along the male thread 411 of the inclination adjustment rod 410, so between the hinge pins 323 facing each other The spacing of the cells becomes longer or shorter. Accordingly, since the lower link 321 and the upper link 321 are opened or folded, one side of the mounting table 200 is elevated.

Here, it is preferable that the lower ends of the lower links 321 are gear-coupled to each other.

In other words, a gear tooth 324 is formed at the lower end of the lower link 321 and disposed so as to be in contact with each other, so that the lower link 321 is smoothly opened and narrowed, and the inclination adjustment rod ( The lower link 321 coupled by the hinge pin 323 through which the 410 simply passes is slid and widened by its own weight if there is no gear tooth.

However, when the gear teeth 324 formed on the two lower links 321 are bitten together, the hinge pin 323 screwed with the male thread 411 does not slide, so the other hinge pin 323 does not move. .

For reference, the inclination adjustment rod 410 may be rotated manually or automatically rotated by controlling with a separate motor.

As another embodiment of the present invention, the bottom of the horizontal plate 110 is formed in a hollow shape with both ends sealed or a buoyant body 500 filled with a foamable resin is combined therein to perform solar power generation on the water. .

That is, power generation may be performed by floating the horizontal plate 110 in the sea, river, or lake.

In addition, the buoyancy body 500 may be made into a hollow shape by blocking both ends of the blank, or may be filled with a foamable resin inside without blocking both ends to float in water.

Hereinafter, the operation of the present invention will be described with reference to FIG. 5. Figure 5 is an operating state diagram of the present invention.

First, a description will be given of a process of operating the mount 200 to track the sun from east to west during a day (see Fig. 5(a)).

In the morning when the sun rises, the mounting base 200 is positioned to face east, and as the sun rises and the altitude increases, the drive motor 340 rotates the rotation shaft at a constant speed.

When the sun is located at a southern mid-high altitude in the afternoon, the mount is horizontal and then continues to rotate to the west at sunset.

And after the sun goes down, the drive motor 340 is automatically controlled to rotate in reverse, so that the mounting base is returned to its original position to face east.

Next, a description will be given of a process of adjusting the inclination so that the mounting plate 200 tracks along the southern middle altitude of the sun for one year (see Fig. 5(b)).

The sun's southern altitude varies with season. In other words, when Korea is the standard, the Namjung altitude is the highest and the winter solstice is the lowest.

When the inclination adjustment rod 410 is manually or automatically rotated during the winter solstice so that the lower link 321 and the upper link 321 are the most open, one side of the mounting table 200 becomes the lowest and the mounting table ( 200) is the largest.

As the sun goes from the winter solstice through the vernal equinox to the summer solstice, the altitude of the sun rises, so if the inclination adjustment rod is rotated in one direction so that the lower link and the upper link are narrowed, one side of the mount is raised and the slope of the mount is reduced.

As the sun goes through the autumnal equinox from the lower extremity and goes back to the winter solstice, the altitude of the sun decreases, so the inclination adjustment rod 410 is rotated in the opposite direction so that the lower link 321 and the upper link 321 open again, so that the mounting base ( By lowering one side of the 200), the inclination of the mounting table 200 increases.

In this way, the mounting plate 200 rotates along the east-west per day and at the same time adjusts the inclination for each season, and is always positioned vertically toward the sun, thereby maintaining maximum power generation efficiency.

Although the exemplary embodiments of the present invention have been described above with reference to the drawings, a person of ordinary skill in the field to which the present invention belongs 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 is limited to the described embodiments and should not be determined, and should not be determined by the claims to be described later, but also by those equivalents to the claims.
