Description

[0001] The present invention relates to a smart maintenance unit for a floating solar cell and a hybrid generator system using a condensing solar cell having self-

The present invention relates to a structure of a photovoltaic device arranged in a water subtype, and more particularly, to a self-cleaning function of a photovoltaic module and a device for self-production of basic power for attitude control of the photovoltaic module.

When two different semiconductors or metals are connected and a temperature difference is given to the junction, an electromotive force is generated. This phenomenon is referred to as a Seebeck effect, and the electromotive force generated at this time is referred to as a thermoelectric power.

The thermo-electromotive force varies depending on the temperature difference of the junction point. The larger the temperature difference? T, the larger the thermo-electromotive force.

For example, when power is produced using the surface temperature of the seawater in the summer and the temperature difference of the solar heat, the temperature in the sea surface water is usually 20 ° C to 25 ° C, and the indoor temperature of the closed automobile , It can be seen that the radiant heat of the sunlight condensed through a plurality of reflectors is higher than this. However, when considering only the closed automobile temperature, the temperature becomes Δt = 65 ° C ~ 80 ° C, and this value satisfies Δt> 40 ° C, which is the feasible temperature difference.

Therefore, for the efficient development, it is necessary to continuously supply the heat source and the cooling source in order to maintain the temperature difference continuously with the maximization of the temperature difference (Δt). Considering that the thermoelectric power generation is a method using a temperature difference, it is natural that the heat source can not be solely discussed. As a heat source, there can be mentioned generally solar heat, waste heat, and methane gas combustion heat. The present invention adopts solar heat, which is an economical and sustainable heat source. Cooling source is the most important factor in the temperature difference power generation as the heat source. Cooling method is divided into air cooling type and water cooling type. The water-cooling method is a method of cooling using water circulation. The reason why water is used for cooling is that the specific heat of water is larger than other liquids. The water-cooled cooling system is divided into a natural circulation system and a forced circulation system. The forced circulation system has excellent cooling characteristics. The natural circulation method is a method in which the water is circulated by the convection of the water in the tank. However, the cooling efficiency is not high, which is inadequate for the thermoelectric power generation. In the forced circulation method, the cooling efficiency is high but energy is consumed. The efficiency is low and the cost is high.

Particularly, in the case of implementing solar power generation, the need for an efficient structure for cooling a high heat source generated when condensing for solar power generation is becoming more urgent for power generation efficiency. In order to increase solar power generation efficiency, It is necessary to have a function of tracking.

Further, in the case of a power generation module which is floated in the water phase, there is a problem that maintenance is difficult and practical use is very difficult. Therefore, it is necessary to implement the cleaning of the equipment itself, even if no personnel for maintenance are mobilized.

Referring to FIGS. 1 to 4 and 5 and 6, as described above, the wave power control module 400 is disposed inside the thermoelectric power generation module 300 and has a function of generating additional auxiliary power using wave energy .

FIG. 6 illustrates the structure of the above-described piezoelectric module constituting the wave power control module 400 described above. The piezoelectric module may comprise a piezoelectric material network structure 402 comprised of a piezoelectric material and a piezoelectric material 404 disposed on the piezoelectric material network structure 402.

To this end, the wave power control module includes a plurality of piezoelectric modules. In general, the piezoelectric module used for power generation and oscillation control is used for cleaning a solar cell module using low frequency ultrasonic waves in a range of 20 KHz to 40 KHz . Such a mechanism has an advantage of consuming low power, and particularly, it has a very excellent effect for particle removal of several μm or more.

Hereinafter, the configuration and operation of the position control module that receives the basic power formed in the thermoelectric module of the present system will be described. The function of the position control module will be described with reference to an enlarged view of the position control module 200 shown in FIG. 8, with reference to the structural views of FIGS. 1 to 4. FIG.

8 is an enlarged view showing the structure of the position control module 200 according to the embodiment of the present invention shown in Figs. 1 to 4, (a) and (b) .

The position control module 200 is disposed adjacent to the reflector module and functions to adjust the inclination of the light incident surface of the reflector module.

Specifically, the position control module 200 adjusts the center of gravity of the rear of the reflector module to control the angle of the reflector so as to adjust the incidence angle of the sun.

The position control module 200 includes a position control plate 210 disposed adjacent to the reflection module support unit 130 that contacts and supports the reflector module 100, And a position control unit 220 which includes a position control unit which is disposed and moves via an outer periphery and a central portion of the position control plate.

In particular, in this case, the position adjusting unit 220 includes at least two guide plates 222 disposed on the position control plate 210 and disposed in the central portion of the outer side of the control plate 210, And a weight adjusting unit 224 that moves the center of gravity of the control plate along the guide unit 222 to move the center of gravity of the control plate.

8 (b), when the weight adjusting part 224 moves toward the center along the guide part 222, the center of gravity moves toward the central part, and the weight adjusting part 224, (224) is not moved, the weight is directed in that direction. Such a mechanism enables the degree of adjustment to be controlled by using the sensing information of the illuminance sensor having the position tracking sensing function disposed in the light-emitting module.

1 and 3, when the center of gravity moves to one side due to the movement of the center of gravity of the position adjusting unit 220, The light incidence surface of the reflector also tilts constantly. The adjustment of the inclination makes it possible to adjust the incidence plane according to the movement of the sunlight.

Basically, the sun moves in a limited manner with a certain rule, which is usually based on the traveling path of the sun moving along the ecliptic. After setting the altitude of the southern part, the weight control unit is moved according to the sun position So that it can cope with the fluctuation of the position of the sunlight.

Alternatively, the inclination of the light collecting module may be changed by correcting the degree of movement according to the degree of sensor detection of the position tracking sensor of the present system, so that the incidence intensity of the sunlight can be always realized with the highest efficiency.

The power required for the movement mechanism of the position control module can be secured by using the basic power generated by the thermoelectric power generation module or the wave power control module. To this end, the position control module 200 may further include a battery unit for receiving power supplied from the thermoelectric module and the wave power control module. In addition, in order to simplify the structure, the battery unit can be mounted inside the housing of the weight adjuster 224.

The solar cell module according to the present invention may further include a solar light oil hole 230 through which solar light is condensed at the reflector module 100 and is transmitted to the solar cell module 500 at a central portion of the position control plate 210 , So that the sunlight to be condensed can be efficiently transmitted to the photovoltaic device on the lower solar power generation module.

Therefore, the sunlight oil hole 230 can be arranged to coincide with the center of the transmission hole 112 provided in the light collecting module 110 of the reflector module.

Through the above position control module, in this system, it is possible to track the sun and secure the incident angle of the sunlight incident on the solar module, generate the basic electric power for driving the solar module through the thermoelectric module, So that the tracking of the sunlight can be realized without supplying any external power source. Further, such a position tracking of the sunlight is provided with a system capable of implementing the inclination control of the reflector, thereby enabling the position control for the solar light incidence to be implemented efficiently.

Hereinafter, the structure of the reflector module 100 for controlling the incident angle of sunlight by the position control module and the operation of the adjacent structures will be described.

With reference to Figs. 1 to 4, the operation will be described with reference to the structure of the light-collecting module shown in Fig. 9 and the structure of the light-transmitting module shown in Fig.

The reflector module 100 of the present system includes a light collecting module 110 having a first reflecting surface 111 having a curvature in a first direction A and a second reflecting surface 111 of the light collecting module 110, And a light emitting module 120 having a second reflecting surface 121 having a curvature opposite to the first reflecting surface 121 and spaced apart from the light collecting module 110.

Particularly, the light condensed by the condensing module 110 is transmitted to the light-emitting module, and the condensed light reflected from the light-emitting module can be transmitted to the photovoltaic module 500.

Therefore, the light-collecting module 120 and the light-transmitting module 120 are spaced apart from each other. Particularly, the light-transmitting module 120 is provided with a fixing member P fixed to the reflecting module supporting unit 130, As shown in FIG.

1 and 3, the reflector module 100 and the position control module 200, the thermoelectric module 300, and the thermoelectric module 300 are disposed in a floating manner in the water, The photovoltaic power generation module 500 is sequentially arranged in a structure in which the vertical central axes X are aligned with each other and the load on the lower portion of the horizontal central axis Y of the thermoelectric power generation module 300 is larger than the load on the upper portion . In this case, the vertical center axis X is defined as a center axis of the reflector module extending in a first direction, and the horizontal center axis Y is defined as a horizontal extension line at a half of the height of the thermoelectric module .

Fig. 9 is an enlarged view of the light collecting module 110 shown in Figs. 1 to 4, and Fig. 9 (a) and Fig. 9 (b) Fig. 10 shows an enlarged view of the light-transmitting module 120 shown in Figs. 1 to 4, and Fig. 10 (a) and Fig.

9 and 10, the light-collecting module 110 includes a first reflection surface 111 having a curvature in a first direction A and a transmission hole 113 ) Can be implemented as a through-hole structure. The light collecting module 110 corresponds to a configuration in which sunlight is primarily incident. The solar light reflected from the reflection surface 121 of the light-transmitting module 120 is placed at the lower portion of the present system. To the solar cell module. The light collecting module 110 is disposed on the opposite side of the reflecting surface 111 so that the reflecting module supporting unit 130 and the supporting unit mounting unit 140 described in FIG. As shown in FIG.

The reflector module 100 according to the exemplary embodiment of the present invention may be configured such that the reflection module support unit 130 and the support unit mount unit 140 are inserted into the light condensing module 110, Respectively. However, as another embodiment of the structure, the light collecting module 110 is removed, the reflector module 100 is implemented by only the reflecting module supporting unit 130 and the supporting unit mounting unit 140, And reflected from the surface of the substrate 130. [

The density of sunlight condensed through the structure of the condensing module of the present system is condensed by the high-density solar light, and condensation is performed at an intensity of 10 to 100 times the incident light. As will be described later, in order to realize such a degree of light condensing, it is possible to control the direction of the incident surface by detecting the change in the position of the southward middle or high altitude of the sunlight through the position control module 200.

The structure of the light collecting module 110 may be embodied in a material that can be floated on the water to match the characteristics of the negative type system. For example, a reflector shape is implemented using a heat resistant plastic structure, A reflective material such as Al may be coated on the slope, and then a water repellent coating may be implemented. Furthermore, a structure such as a joint which is basically connected to the structure of the light collecting module 110 can prevent corrosion by black anodizing.

The structure shown in FIG. 10 shows a structure of a light-transmitting module 120 disposed at a position opposed to the light-collecting module 110.

The light-transmitting module 120 includes a second reflecting surface 121 having a curvature that is opposite to the first reflecting surface of the light-collecting module 110, and is disposed apart from the light-collecting module 110 do. Accordingly, the light condensed by the condensing module 110 is transmitted to the light-emitting module, and the condensed light reflected by the light-emitting module can be transmitted to the photovoltaic module 500.

For this, the light-collecting module 120 concentrates the light condensed by the light-collecting module 110 at one point at the center of the reflecting surface 121 of the light-transmitting module, and adjusts the reflection angle of the concentrated light, So that the angle of the reflecting mirror can be adjusted so as to be perpendicularly incident on the reflecting mirror.

The light-transmitting module 120 may be formed of a material that can be floated on the water to meet the characteristics of the negative type system. For example, after the reflector type is implemented using the heat-resistant plastic structure, ) May be coated with a reflective material such as Al, followed by a water repellent coating. Further, it is possible to provide a heat insulating material on the aluminum (Al) material, and to provide a position tracking sensor 125 such as an illuminance sensor thereon. As will be described later, in the case of the heat insulating material, the heat of the light-transmitting module heated by the condensed light is transmitted to the thermoelectric module through the fixing member ('P' in FIGS. 1 and 2) can do. Accordingly, the high temperature portion of the thermoelectric power generation module is formed at a higher temperature and the temperature difference (Δt) between the thermoelectric power generation module and the low temperature portion can be further increased. This realizes the effect of further increasing the efficiency of generating the basic power in the thermoelectric module described later.

Hereinafter, the configuration and operation of the reflection module support unit 130 for supporting the above-described reflector module will be described with reference to FIGS. 11 and 12. FIG.

11 and 12, Fig. 11 is an enlarged view of the reflection module supporting unit 130, and Fig. 11 (a) is an enlarged view of the reflection module supporting unit 130 in the A direction (b) FIG.

In this case, the light-collecting module 110 functions as a kind of cover member and can have a first reflecting surface having the same curvature as the curvature surface of the surface of the reflecting module supporting unit 130.

The light collecting module 110 is removed and the reflecting module supporting unit 130 and the supporting unit mounting unit 140 are inserted into the light collecting module 110. [ It is also possible to implement the reflector module 100 with only the support unit 130 and the support unit seating unit 140 and to reflect the sunlight on the surface of the reflector support unit 130.

The reflection module supporting unit 130 is disposed on the rear side of the light collecting module 110 and is disposed on the rear side of the light collecting module 110. The light collecting module 110 is disposed on the position control module 200, And an inner surface 131 having the same curvature as that of the inner surface 131.

The basic function of the reflection module supporting unit 130 is to realize a function of stably supporting the light collecting module 110 and to provide a function of the light collecting module 110 Function can be substituted. In this case, the configuration of the light collecting module 110 can be omitted in the present system, and the load on the entire apparatus can be further reduced. That is, the reflection module supporting unit 130 and the condensing module may be integrated.

Accordingly, the material of the reflection module supporting unit 130 may be formed of a lightweight porous heat insulator so as to have a negative type property. In the case of the support unit seating part 140, Al and the like.

The reflection module supporting unit 130 has a second through hole 132 formed in the center thereof and is disposed so that the central axis coincides with the through hole 111. Light reflected by the light- .

Fig. 12 illustrates a support unit seating portion 140 in which the reflection module support unit 130 of Fig. 11 can be seated in an engaging manner. That is, the protrusions a, b, and c of the reflection module support unit 130 of FIG. 11 are seated in the space between the seating protrusions 141 and 142 in a fitting manner. Such a structure can make it possible to support the reflector with a more stable structure.

FIG. 13 is a schematic diagram of a photovoltaic power generation module for performing photovoltaic generation in the photovoltaic device according to the embodiment of the present invention.

In this case, the solar power generation module 500 is defined as a structure including a solar module including a solar module and a module for receiving solar heat to perform power generation.

1 and 3, the photovoltaic power generation module 500 is mounted on the seating groove portion 605 at the center of the cooling module 600 disposed in contact with the rear of the solar power generation module 500 .

The low temperature portion of the thermoelectric module 300 is disposed in the upper direction of the solar power generation module 500 and is disposed opposite to the plan structure of the wave power control module 400 disposed on the cavity portion.

In particular, the photovoltaic module 500 having the structure shown in FIG. 13 is seated in a structure to be inserted into a seating part 605 implemented on a cooling plate 610 of the cooling module 600. As shown in FIG. 14, in the cooling module 600, a heat source generated from the solar power generation module 500 can be transmitted to the outside by contacting the cooling module. In order to maximize the heat dissipation effect, a plurality of protrusive cooling fins 620 may be formed on the outer surface of the cooling module 600. The cooling fins 620 can widen the surface area to further widen the contact area with water and further improve the heat radiation efficiency.

The shape of the cooling module is not limited to the structure shown in FIGS. 1 to 4, but may be variously modified. For example, referring to FIG. 18, this illustrates one embodiment of the cooling module 600. The structure of the cooling module may be a structure having a plurality of cooling fins for widening the contact area. However, the present invention is not limited thereto, and a known structure such as a cooling fin or a cooling pattern can be employed.

The reason why the cooling module 600 is installed in the present system is that, as shown in FIG. 15, a temperature rise due to light condensation occurs in the light oil of a structure for generating solar power in general and a high efficiency solar module, Drop.

That is, referring to the graph of FIG. 15, it can be seen that as the temperature of the panel increases, the power generation efficiency sharply decreases as the maximum power generation rate of the solar panel increases.

Therefore, a cooling function for preventing such power generation efficiency is essential. In this system, the heat dissipation is realized by the water-cooling type, and the heat dissipation effect can be further improved by using the cooling module.

In addition, in the present system, a part of the system is applied as a submerged structure (submerged type), which is considerably effective in terms of cooling effect because light is modulated within a range of 10 cm to 30 cm The energy transfer efficiency is equal, and since water cooling can be performed, the semi-submergible structure of the present system is advantageous for cooling.

16 is a sectional view of a combined photovoltaic device according to the present invention as shown in FIG. 1 through FIG. 4, when a unit structure is realized with a regular polygonal structure in order to secure an effective space, A power generation system can be constructed.

That is, a plurality of unit complex solar photovoltaic devices pw ₁ to pw _n may be disposed adjacent to each other to realize a large floating structure. Of course, in this case, as described above, it is possible to secure a space by implementing a hexagonal close-packed structure. However, such a shape can be realized by a rectangular structure. In order to minimize local stress due to algae and wave, It is also possible to arrange it.

17 is an image for explaining the application principle of the present invention with respect to the use efficiency of the sunlight. Fig. 17 (a) shows the efficiency of the high efficiency solar module, and Fig. 17 (b) is an image of the water penetration depth according to the wavelength of sunlight.

In the case of the solar module, the efficiency is increased by a certain amount as the light is condensed, but there is a problem that the power generation efficiency is lowered when the temperature rises. Therefore, in the case of a solar power generation module as a main power source, it is necessary to provide a high efficiency solar module and a heat dissipation structure. However, in the case of a high efficiency photovoltaic module, the material is expensive and the structure is complicated.

In order to cool an efficient photovoltaic module, a heat dissipation structure having a large surface area is essential. However, there is a limitation in a modular structure having a limited size. In order to increase the cooling efficiency, cooling of the submerged structure It is highly desirable to implement. In the case of an underwater immersion type structure, when the portion where the solar cell is placed is shallowly immersed in water, and the light is within 10 cm from the water surface, the light enters the module almost equally. Even if immersed in water, There is no concern. It is possible to simultaneously enhance the effect of cooling, and it is also based on this principle that the semi-submerged arrangement of the embodiment of the present invention can effectively implement the effect.

That is, as shown in FIG. 17 (b), it is possible to increase the power generation efficiency by using only the wavelength region band (blue, green) used for power generation and the other wavelengths are portions with low energy density, There is almost no influence on the efficiency.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical idea of the present invention should not be limited to the embodiments of the present invention but should be determined by the equivalents of the claims and the claims.
