Hereinafter, as shown in detail in FIG. 1 , a direction in which sunlight is irradiated the most during the day and can collect the most sunlight is referred to as a front, and directions of the side and the rear are defined based on this.

As shown in these drawings, the water photovoltaic power generation system according to the first embodiment of the present invention includes a photovoltaic power module 100 , a water support module 200 , and an overturn prevention module 300 .

First, the photovoltaic power module serves to perform photovoltaic power generation by condensing sunlight and directly converting it into electric energy.

In the case of a photovoltaic power generation system installed on the ground, a plurality of photovoltaic power generation unit modules are combined to form one large photovoltaic power generation module, but the photovoltaic power generation module 100 installed on the water is a plurality of photovoltaic power generation units It is provided with the module 110, but is arranged to be spaced apart from each other with a predetermined interval.

This type is called a stand-alone type to distinguish it from the fixed type installed on the ground, which has the advantage of preventing the large type of combined solar power module from being damaged by the sloshing of the water surface.

However, in this way, when the wind blows while the plurality of photovoltaic unit modules 110 are floating on the water surface, each photovoltaic unit module 110 is easily affected by the wind, If the influence becomes large, a problem that a part or all of the solar power module may be overturned or damaged may occur.

In addition, if the solar power generation unit module 110 is slanted so that the solar panel faces the front, which is the direction in which sunlight is irradiated the most during the day, in order to increase the collecting efficiency of sunlight, this risk becomes greater do.

Therefore, the floating photovoltaic power generation system according to the present invention further includes a water support module 200 and an overturn prevention module 300 to be described below, so that it has a simple structure that can be easily installed and can reach the photovoltaic module It is possible to effectively block the influence of the existing wind, and it is possible to prevent a part or all of the solar power module from being overturned or damaged.

Next, the water support module 200 is coupled to the photovoltaic power module 100 serves to support the photovoltaic power module 100 to float on the water.

The water support module 200 includes a plurality of water support vertical modules 210 , a plurality of water support horizontal modules 220 , and a plurality of unit water support standing walls 230 .

A plurality of water support vertical modules 210 are provided to be spaced apart from each other, and each serves to support the solar power unit module 110 at an angle.

As shown in detail in Figure 2, a plurality of water support vertical modules 210 are coupled adjacent to each other to form one vertical support line (L1, L2, L3, L4), a plurality of vertical support lines (L1) , L2, L3, L4) are arranged side by side to form the basis of a floating photovoltaic power generation system having an overall rectangular shape.

At this time, all water support vertical modules of the outermost vertical support line (L1) and all vertical support lines L1, L2, L3, L4 water support vertical modules 210 located at both ends of the solar power generation unit module (110) ) is not coupled, and the rollover prevention module 300 to be described later is coupled.

That is, instead of the solar power unit module 110 being disposed on the edge of the floating photovoltaic power generation system having an overall rectangular shape, the overturn prevention module 300 is provided to blow the wind blowing inward from the outside first along the slope. By flowing it, it is possible to prevent the wind from being transmitted to the solar module disposed in an adjacent position, thereby reducing the influence of the wind, and the remaining force applied to the overturn prevention module 300 by the wind is also directed toward the water surface. While forming a downforce that pushes the buoyancy body supporting the solar panel toward the water and offsetting it with the buoyancy force of the buoyancy body, it reduces the force transmitted to the photovoltaic module disposed in an adjacent position to stabilize the structure. Thus, it is possible to effectively protect not only the photovoltaic unit module 110 located outside but also the photovoltaic unit module 110 located inside.

On the other hand, the water support horizontal module 220 is arranged spaced apart from each other to serve to connect the water support vertical module 210, as shown in detail in Figure 2, a plurality of vertical support lines (L1, L2, L3) , L4) are arranged to be spaced apart from each other by a predetermined interval and both ends are respectively coupled to the water support vertical module 210 of the different vertical support lines (L1, L2, L3, L4).

For example, between the vertical support lines L1 and L2, water support

horizontal modules

220a, 220b, 220c are coupled to fix the vertical support lines L1 and L2.

According to an embodiment of the present invention, the water support vertical module 210 and the water support horizontal module 220 are formed in grooves at staggered positions so that parts can overlap each other, and by providing a connection hole in each groove, It has been provided to enable binding by a connecting member such as, but the present invention is not limited thereto and may be coupled in various ways.

Since this water-supporting horizontal module 220 may serve as a footrest on which the operator can move, it may have a concave-convex structure in which a plurality of protrusions are formed to prevent the operator from slipping.

On the other hand, the unit water support standing wall 230, as shown in detail in FIG. 5, is placed upright on the water support vertical module 210 to support one side of the photovoltaic unit module 110.

By supporting one side of the photovoltaic power generation unit module 110 in this way, the photovoltaic power generation unit module 110 can be disposed to be inclined toward the front, thereby increasing the solar light collecting efficiency.

However, by arranging the photovoltaic unit module 110 inclined in this way, the front, which is the direction in which the solar panel of the inclined surface faces, can increase the light collecting efficiency, but in the case of the rear, by the wind blowing from the rear There is a risk that the photovoltaic unit module 110 may be overturned or damaged, and such overturning or damage may also occur by wind blowing from both sides.

The overturn prevention module 300 for preventing some or all of the photovoltaic power generation module from being overturned or damaged by blocking the influence of such wind will be described in detail later.

Hereinafter, the coupling structure of the water support vertical module 210 and the photovoltaic unit module 110 will be described with reference to FIGS. 4 to 6 .

As shown in detail in Figures 5 and 6, the unit water support erected wall 230 has a locking jaw 231 is formed so as to be engaged with one side of the photovoltaic unit module 110, and as shown in detail in Figure 4 Likewise, the water support vertical module 210 includes an anchor set 211 for fixing the other side of the photovoltaic unit module 110 .

First, in a state in which the water support vertical module 210 and the unit water support erecting wall 230 are coupled, one side of the photovoltaic power generation unit module 110 is placed on the protrusion 231 of the unit water support standing wall 230. When hanging, the photovoltaic unit module 110 is fixed to the unit water-supporting wall 230 by a natural load action by the inclined arrangement of the photovoltaic unit module 110 (see FIG. 6).

At this time, the unit water support standing wall 230 may be further provided with a support protrusion 232 to more firmly hold the photovoltaic unit module 110 .

Next, at the position where the other side of the photovoltaic unit module 110 meets the vertical water support module 210, the hooking part 211a of the anchor set 211 is hung on the other side of the photovoltaic unit module 110, and the anchor When the unit is fixed by inserting it into the vertical water support module 210 , the combination of the water support module 200 and the photovoltaic unit module 110 is completed.

As such, by having a coupling structure in which one side is simply engaged and the other side is engaged and coupled at the same time, the photovoltaic unit module 110 can be simply and easily fixed, while maintaining a strong coupling.

On the other hand, the overturn prevention module 300 is coupled to at least one edge of the water support module 200 serves to prevent the at least one solar power generation unit module 110 from overturning by the wind.

The overturn prevention module 300 is inclined along at least one edge of the water support module 200 to prevent the solar power generation unit module 110 from being overturned by the wind. do.

It is possible to turn over, while preventing the solar power unit module 110 from overturning, it is possible to stably maintain the floating solar power system.

Here, the part described as an obtuse angle means a shape lying by a predetermined angle toward the photovoltaic unit module 110, and the predetermined angle is determined in relation to the inclination angle at which the photovoltaic unit module 110 is disposed. do. For example, if the solar power unit module 110 is inclined at an inclination angle of 12 degrees to 15 degrees, the overturn

prevention wall parts

310 and 320 may also be inclined at an inclination angle of 12 degrees to 15 degrees. This arrangement allows the most sunlight to be condensed, while allowing the blowing wind to flow naturally. However, the present invention is not limited to the above inclination angle, and if the inclination angle of the photovoltaic power generation unit module 110 is changed according to the south-middle altitude of the sun, the inclination angle of the overturn

prevention wall parts

310 and 320 may also be changed.

In addition, the upper ends of the overturn

prevention wall parts

310 and 320 are disposed higher than the highest height of the upper surface of the photovoltaic unit module 110 , so that the wind cannot affect the photovoltaic unit module 110 .

At this time, as described above, in relation to the inclined arrangement of the photovoltaic unit module 110 , the front toward which the solar light collecting plate, which is the upper surface part of the photovoltaic power unit module 110 , is directed is the wind blowing in the inclined plane. The risk of overturning is reduced by being stabilized by the downforce formed by the , but in the case of the rear and both sides, there is a risk that the solar power unit module 110 may be overturned or damaged by the blowing wind. .

That is, as described above, the rollover prevention module 300 is provided to flow the wind blowing from the outside in the inward direction first along the inclined surface, thereby preventing the wind from being transmitted to the solar module disposed in the adjacent position. It is possible to reduce the influence of the wind, and the remaining force applied to the overturn prevention module 300 by the wind also forms a downforce that pushes the buoyancy body supporting the solar panel toward the water while facing the water surface direction, and this buoyancy body By offsetting the buoyancy of the photovoltaic module 110 located on the inside as well as reducing the force transmitted to the photovoltaic module disposed in the adjacent position to serve to stabilize the structure, as well as the photovoltaic power unit module 110 located outside It is possible to effectively protect even the power generation unit module 110 .

Therefore, in this embodiment, the rollover
