Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a concentrating device for a solar power generation,

More particularly, the present invention relates to a condensing apparatus for a solar power generation, and more particularly, to a condensing apparatus for a solar power generation, in which the sun moves in accordance with the direction of sunlight changing with altitude change and reflects sunlight to a solar panel, And more particularly, to a condensing apparatus for a solar power generation system capable of preventing the efficiency from being lowered due to pollution and weather conditions, thereby increasing power generation efficiency.

Generally, photovoltaic power generation is used as renewable energy as alternative energy due to problems of depletion of fossil fuel and environmental pollution.

These solar power generators are largely classified into a fixed system and a position tracking system. The fixed system is based on a comprehensive analysis of the altitude and sunshine of the sun to fix the system at the most appropriate angle and orientation. And the angle of the solar panel is changed.

At this time, the solar panel is calculated so that the sunlight can be collected on the flat large-scale site, the mountainous terrain, etc., and can be installed efficiently on the site.

However, when a plurality of solar panels is installed through precise calculation, shading occurs when the angle of the solar panel is adjusted according to the amount of sunshine, and the sunlight can not be absorbed sufficiently because it can not rise above a certain angle.

In addition, as the four seasons change in the domestic environment, the sun altitude and the amount of sunshine change, and it is necessary to calibrate from time to time.

In order to solve such a problem, the conventional art is provided with reflector means installed on one side of the PV module to increase the amount of incident light of the sun to reflect the amount of light incident on the outside of the PV panel to induce the PV panel to increase efficiency .

However, as the reflector means is installed outside the PV panel, the PV panel shading increases and the efficiency of the PV panel installed at the front or rear is lowered due to the shading.

Also, as the shade increases, the installation interval of the PV panels is widened, and relatively low PV panels are installed in a certain space.

The frame 110 may further include a first sensing sensor 135 for monitoring whether the reflective film 133 moves due to the rotation of the drive shaft 131.

This is because when the light condensing is not smooth due to the contamination of the reflective film 133 moving along the drive shaft 131 and the trajectory of the driven shaft 132, the reflective film 133 positioned at the bottom is moved upward, Identify the moved state.

The drive shaft 131 and the driven shaft 132 can be mutually displaced according to the installation of the drive motor 134 and the first detection sensor 135 detects the movement of the reflection film 133 It can be installed in various positions.

As shown in FIG. 4, the winding system has the same configuration as that of the drive shaft 131, the driven shaft 132, the drive motor 134, and the reflection film 133.

The reflective film 133 is wound on the driven shaft 132 in a roll manner and an end of the reflective film 133 is coupled to the drive shaft 131 and is moved by the rotation of the drive shaft 131.

Accordingly, the light collecting unit 100 is installed on the upper side of the solar panel 200 and on both sides of the moving unit 120 installed on the ground to adjust the angle.

Accordingly, it is possible to reflect the amount of incident light incident between the solar panel 200 and the solar panel 200 provided with a plurality of solar panels 200 according to the rise of the sun and the amount of incident light, To be condensed.

Hereinafter, as shown in FIG. 5, the sunlight is reflected and the condensing operation is performed through the solar panel 200.

First, a plurality of solar panels 200, such as a flat or mountainous area, are installed to install the light collecting means 100 in a facility where electricity is generated, as described above.

In order to increase the efficiency, the solar panel 200 analyzes the angle of altitude and incident amount of sunlight according to the installation area, and then controls the angle and distance of the solar panel.

That is, it is preferable to set the light source so that light can be condensed easily through the sun information in the installation area at the time of initial installation.

In addition, after the initial setting is made, the condensing means 100 can be manually and automatically operated.

In order to do this, the user may directly manipulate the condenser 100 by a user or a manager through a control unit that can operate a separate motor, and it is preferable that the operation method includes all the methods described below.

These algorithms and programs are achieved through separate control modules.

Accordingly, the reflector 130 is adjusted in the following manner through a manual and automatic control method.

First, as described above, the angle of incidence is changed so that light is incident on the solar panel 200 positioned at the rear by reflecting the amount of light incident on the sun.

In consideration of the overall efficiency, the angle of the solar panel 200 can be adjusted in real time according to the fixed angle and the altitude of the sun to adjust the angle of reflection.

At this time, the movement of the reflection film 133 is rotated within a range of moving along the rail part 121 in the longitudinal direction, so that the rail part 121 can be adjusted in length Adjust it.

The reflector 130 and the rail 121 can be supported by tension through the tension member 123 at a position close to the interval between the reflector 130 and the rail 121, The tension member 123 can be supported by the tension of the tension member 123.

The tension member 123 can be adjusted when the tension member 123 is installed so that the tension member 123 can be supported at a position close to the gap.

In addition, when the reflection film 133 is contaminated, it can be operated through a track system and a winding system, and can be condensed through the uncontaminated part. In addition, the reflection film 133 can detect snowfall in winter, Can operate.

First, when the condensing efficiency of the reflective film 133 is reduced, the drive motor 134 rotates the drive shaft 131 to move the reflective film 133 located on the rear surface upward to condense sunlight .

At this time, the light-condensing efficiency is detected by directly sensing the contaminated state of the reflection film 133 through the sensor or by detecting the condensed state of the plurality of the solar panels 200 and the condensed light efficiency data of the previous period, The part can be measured.

At this time, the moving part of the reflection film 133 is sensed through the first sensing sensor 135 and precise movement is performed, so that it is possible to prevent the movement of the driving shaft 131 and the driven shaft 132 from being unstable.

When the rain is detected, the contaminated part is exposed to the outside and cleaned through the rainwater.

In addition, the weight of snow covered in the winter can be detected through a separately installed load cell or the like, and the snow may be cleaned by rotating the reflection film 133 when the weight of the reflection film 133 is increased.

And, the winding method can judge the contamination state in the same way as the orbit method.

When the contaminated state is determined, the reflective film 133 wound around the driving shaft 131 is moved to expose the uncontaminated portion to the outside, and the contaminated portion is wound around the driving shaft 131.

At this time, the movement of the reflective film 133 can accurately determine whether the reflective film 133 is moved through the rotation speed of the driving shaft 131 or the driving motor 134 rotated through the second sensing sensor 136.

In addition, when the snow weight of the snow is sensed, the snow may be cleaned by moving the reflection film 133.

In this way, the efficiency of focusing can be improved by operating fluidly according to the change of the altitude of the sun. Even if it is contaminated by the external environment, it can be detected in real time and used for a long time.

In addition, it can prevent damage and breakage caused by winter snow, and can be individually cleaned depending on whether it is contaminated.
