A photovoltaic module is a solar cell module in which a minimum unit of a solar cell that generates electricity using such a photoelectric effect is a cell, and a plurality of cells are connected in series or in parallel to generate a predetermined amount of power. A typical photovoltaic power generation system generates electricity by connecting a plurality of solar modules in series or in parallel.

A photovoltaic power generation system is disclosed in Patent No. 0959554. The disclosed photovoltaic power generation system is fixed to a flat or inclined place by a plurality of support pillars.

Such conventional photovoltaic generation system is fixed to the ground by the pillars, and thus it is impossible to transfer the photovoltaic generation module until the lifetime of the photovoltaic module is over. Therefore, if the land where the PV system is installed should be used for other purposes, there is a problem of complicated demolition process.

In addition, there is a problem that maintenance work is costly when the ground subsidence occurs because the civil works are not properly performed when the solar power generation system is installed.

To solve these problems, a water solar power generation system that is installed on a water surface of a reservoir, a dam, and the like is recently being developed. However, the pilot solar photovoltaic power generation system, which has been installed and operated to date, is still in the test phase, requiring 1.5 ~ 3 times of the land installation cost, and durability and stability are not ensured.

 On the other hand, in the case of a solar photovoltaic power generation system, when the solar power generation module sinks on the bottom surface in the wet season, the photovoltaic generation module can not be flexibly faced to the uneven floor surface, There is a problem in that the connection portion of the second lens unit is twisted and damaged.

However, development of a technique capable of solving such a problem in the past has been limited.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a water solar power generation system in which the solar power generation module is improved in structure so as not to be damaged even when the solar power generation module touches the floor.

Another object of the present invention is to provide an aquarius solar power generation system capable of maintaining the solar power generation efficiency constant by minimizing the shade that can be generated by the front solar power generation module by adjusting the separation distance between neighboring support frames .

 It is still another object of the present invention to provide an aquarius solar power generation system capable of preventing damage when a plurality of neighboring support frames collide with each other by wind or wave.

It is still another object of the present invention to provide an aquarium photovoltaic power generation system that can be easily expanded and reduced in various sizes depending on the purpose of use and installation location.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention by those skilled in the art.

The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1 is a perspective view, a plan view, and a side view showing a configuration of an aquatic power generating system 100 according to a preferred embodiment of the present invention.

As shown in the drawings, the aquarium power generation system 100 of the present invention includes a support frame 110, a solar power generation module 120 installed on the support frame 110, a solar power generation module 120, A buoyant body 140 accommodated in the support frame 110 to form a buoyancy force to move the support frame 110 up and down according to a water level, And a connecting wire 150 connecting the frames 110 to each other.

The support frame 110 receives the buoyant body 140 therein and moves up and down according to the height of the water surface. The support frame 110 is formed to correspond to the size of the plurality of solar power generation modules 120. At this time, the number of the photovoltaic modules 120 accommodated in the support frame 110 is determined in consideration of the installation site and the flow rate of water.

The support frame 110 is formed of a metal material having durability. In some cases, the support frame 110 may be coupled with a reinforcing member (not shown) on the plate surface to reinforce the strength.

Fig. 2 is an enlarged perspective view of the structure of the support frame 110. Fig. As shown in the figure, a wire holder 111 and a cross holder 113 for supporting the connection wire 150 are provided on the side of the support frame 110 at regular intervals. The wire holder 111 is provided such that the connection wires 150a and 150b penetrate the inside thereof. The cross holder 113 supports the plurality of connection wires 150 coupled to the vertex area of the support frame 110 and connected to each other in a crossed manner to be connected together. The wire holder 111 and the cross holder 113 are formed larger than the diameter of the connection wire 150 so that the connection wire 150 can be easily inserted.

The cross holder 113 is formed in a " + "shape, and the connection wire 150 is inserted into the cross holder 113 and then fastened with bolts so that the connection wire 150 is fixed inside the cross holder 113. The structure of the cross holder 113 allows the connection wire 150 coupled to the side surface of the support frame 110 and the connection wire 150 connecting between the neighboring support frames 110 to be coupled to each other. In addition, since the plurality of support frames 110 can be coupled and separated by the connection wires 150 through the cross holder 113, the scale of the entire aquarius solar power generation system 100 can be easily expanded and contracted .

The solar power generation module 120 is provided on the support frame 110 to absorb solar light and convert it into electrical energy. A plurality of solar power generation modules 120 are coupled together on the support frame 110. The module supporting part 130 supports the solar cell module 120 on the support frame 110 so that the solar cell module 120 is disposed at a predetermined angle. The module support unit 130 adjusts the angle of the solar power generation module 120 such that the solar power generation module 120 is arranged at an angle to absorb sunlight as much as possible according to the altitude of the sun.

The buoyant body 140 is accommodated in the support frame 110 to form buoyancy so that the support frame 110 on which the solar power module 120 is installed is floated on the water surface. The buoyant body 140 may be integrally formed or assembled in accordance with the size of the support frame 110. The support frame 110 is moved up and down according to the water level by the buoyancy member 140. [

The connection wires 150 connect the neighboring support frames 110 to each other. The photovoltaic power generation system 100 of the present invention is divided into a plurality of support frames 110 and the photovoltaic modules 120 are dispersedly disposed on the support frames 110. Then, the support frame 110 is connected by the connection wire 150. Since the connecting wire 150 has elasticity to be bent, each supporting frame 110 connected to the connecting wire 150 can be independently moved up and down. The connection wire 150 is formed of a material having elasticity within a certain range.

Accordingly, in the flood season, a plurality of support frames 110 are floated on the water as shown in FIG. 1 (c) by the buoyant member 140, and even in the wet season when the water level is lowered due to drought or the like Each support frame 110 is seated on the floor G as shown in Fig. 3 (a).

At this time, since the height of the floor G is different from each other, the connecting wire 150 having elasticity is bent so that the plurality of supporting frames 110, 110a, 110b and 110c are also different in height h1, h2, h3 and h4 And is seated on the floor (G).

However, the connection wire 150 is provided to have strength and rigidity to support the support frames 110 stably without being easily broken by the wind or the flow velocity even if they have elasticity. For this purpose, the connecting wire 150 is formed in such a manner that a plurality of steel wires are twisted together.

The connection wire 150 is coupled to the outer circumferential surface of the support frame 110 while being accommodated in the wire holder 111 of the support frame 110. The adjacent support frames 110 are joined by the cross holder 113.

The spacing 12 between adjacent supporting frames 110 is selected so as not to affect the solar power generation module 120 located behind the shadow of the solar power generation module 120 located at the front. As the distance between the spacing 12 increases, the solar absorption rate is not affected. However, the flow range of the support frame 110 can be increased due to the flow velocity.

On the other hand, the fender 151 for preventing the impact and maintaining the gap is connected to the outside of the connection wire 150 in a single or a plurality. The fender 151 means a buffer used to mitigate the impact caused by contact and prevent damage to each other. Urethane fenders using urethane, cork fenders using cork, wooden fenders using logs, fenders using dunnil wood, rubber fenders using rubber, and tire fenders using old tires can be used. In the present invention, the connecting wire 150 is elastic and can be bent. As described above, when the solar power module 120 is seated on the bottom surface in the rising season, (120). At this time, the photovoltaic power generation module 120 or the support frames 110 may collide with each other and collide with each other. The fender 151 plays a role as a buffer to buffer shocks. In addition, when the connection wire 150 is bent due to wind or flow velocity, the support frame 110 is prevented from being hit and damaged. Since the fender 151 is provided to have a predetermined shape, the interval between the neighboring support frames 110 is maintained as much as the length of the fender 151.

7 is an exemplary view showing a state of connection between the connection wire 150 and the fender 151. FIG. As shown in FIG. 7 (a), the fender 151 may be formed to be coupled with the outer surface of the connection wire 150. That is, the connection wire 150 is received in the fender 151.

In addition, as shown in FIG. 7 (b), the connecting wire 150 is coupled to both ends of the fender 151a. In this case, both ends of the fender 151a and the end of the connecting wire 150 are detachably coupled to each other in the form of a loop. When the adjacent fenders 151a are connected by the separated connecting wires 150, a plurality of bending points are formed between the fenders and the fenders, so that the wire fender structure having a more flexible structure can be formed.

The operation of the aquatic solar power generation system 100 according to a preferred embodiment of the present invention having such a configuration will be described with reference to FIGS. 1 to 3. FIG.

The support frame 110 is formed to correspond to the number of the plurality of solar power generation modules 120. [ 1, the four solar power generation modules 120 are supported by one support frame 110. However, this is only an example, and various numbers of the solar power generation modules 120 may be supported by the support frame 110 As shown in FIG.

The buoyant body 140 is coupled to the inside of the support frame 110. Then, the connection wire 150 is coupled to the wire holder 111 formed on the side surface of the support frame 110. The connection wire 150 is inserted into the wire holder 111 and the four sides of the support frame 110 are coupled to each other in such a manner as to surround the connection wire 150.

When the connection wires 150 are coupled to all of the plurality of support frames 110, the plurality of support frames 110 are connected to each other by the connection wires 150. To this end, the connection wire 150 is connected to the cross holder 113 of the support frame 110 as shown in FIG. The connection wire 150 is inserted into the cross holder 113 and the bolt is fastened to the insertion end to fix the position of the connection wire 150. [

At this time, the connecting wire 150 is covered by the fender 151. [

In this process, the plurality of support frames 110 are connected to each other by a connecting wire 150 in a lattice form. As shown in FIGS. 1 (a) and 1 (b), a plurality of support frames 110 coupled by a connection wire 150 are spaced apart from each other at regular intervals.

In this state, as shown in FIG. 1 (c), the solar power generation is performed by being located in the water.

3 (a) and (b), when the bottom G is exposed, the lower portions of the support frames 110, 110a, 110b, (G). Since the height of the floor G is not constant at this time, the supporting frames 110, 110a, 110b, and 110c contacting the floor G having different heights are also bent at different heights h1, h2, h3 and h4, respectively. Due to the elasticity of the connecting wire 150, the supporting frames 110, 110a, 110b, and 110c can be seated to correspond to the curvature of the bottom surface. At this time, when the connecting wire 150 is bent, the fender 151 prevents the support frames 110 from being hit by each other to be damaged.

On the other hand, the length of the connection wire 150 may be different depending on the position. For example, as shown in FIG. 1C, the length of the connecting wire 150 may be different (W1? W2) depending on the arrangement position of the support frame 110. The length of the connecting wire 150 can be adjusted in consideration of the illuminance of the sunlight and the shadow forming area.

4 and 5 are views showing a configuration of an aquamarine solar power generation system 100a according to another embodiment of the present invention.

The water PV system 100 according to the preferred embodiment of the present invention is implemented in such a manner that one support frame 110 supports a plurality of solar power generation modules 120 together. On the other hand, the aquamarine solar power generation system 100a according to another embodiment of the present invention is realized in such a manner that one support frame 160 supports one solar power generation module 120. That is, the aquamarine solar power generation system 100a of another embodiment than the aquatic solar power generation system 100 of the preferred embodiment is partitioned and formed into smaller units.

In the aquamarine solar power generation system 100a according to another embodiment, a module support unit 130 and a solar power generation module 120 are installed on a support frame 160. A side surface buffer member 170 for supporting the connection wire 150 is provided outside the support frame 160.

Here, the support frame 160 is formed of a material having buoyancy. That is, the support frame and the buoyant body of the preferred embodiment described above are integrated.

As compared with the aquarium power generation system 100 according to the preferred embodiment described above, since the support frames 160 of a relatively small size are individually supported by the connection wires 150, the flow of the support frames 160 may be large have. A side surface cushioning member 170 for relieving the impact on the side surface of the support frame 160 to prevent the support frame 160 from being damaged by collision with the neighboring support frame 160, .

As shown in FIG. 5, the side cushioning material 170 is made of a material having elasticity, and a space through which the connection wire 150 moves is formed inside. The connection wire 150 extends to the vertex side of the support frame 160 through the side cushioning material 170 and is coupled to the cross holder 173. [

In this combined photovoltaic power generation system 100a, each of the support frames 160 to which one photovoltaic module 120 is coupled can be independently positioned at the floor G at different heights, Even if installed in a place with a high level of unbalance, the position can be adjusted according to the height of the floor (G), thereby preventing breakage of the PV module and using the PV module without twisting or warping at the connection portion connecting the PV module.

On the other hand, Fig. 6 is an exemplary view showing a modified example (100b) of the aquamarine power generation system of the present invention. As shown, the photovoltaic power generation system 100b can be provided with a footing 180 on the connecting wire 150 to facilitate management of the manager.

The pedestal 180 may be provided at both ends in the form of hooks 181 and 183 to facilitate mounting on the connecting wire 150. The hook 181 is inserted into the connecting wire 150 so that the position of the foot plate 180 can be fixed without a separate restraining member. The pedestal 180 is preferably provided in the form of a perforated plate to facilitate water drainage.

As described above, the water photovoltaic generation system of the present invention is formed by separating the entire solar photovoltaic module into a form in which the support frame does not support one support frame and a few solar PV modules are supported by the support frame. Further, even if the separated plurality of support frames are connected to each other by the connection wire and reach the bottom of the floodgate, the height of the plurality of support frames can be independently adjusted to match the shape of the floor.

Accordingly, breakage of the solar cell module can be prevented, and warpage and twisting of the connecting portion connecting the neighboring supporting frame can be prevented, so that it can be used stably for a long period of time.

Also, by adjusting the length of the connecting wire, the shading between the solar modules provided in the neighboring supporting frames can be minimized, thereby maximizing the solar power generation efficiency.

In addition, since the connection wire is light in weight and low in unit price compared to a frame made of a conventional metal material, there is an advantage in that the weight of the entire aquatic power generation system can be lightened.
