In this embodiment, the coupling plate 328 is provided in a pair, and the coupling plate 328 is provided only at the coupling position with the solar panel support structure 140, thereby reducing the overall weight of the floating body 120. There is an advantage.

Meanwhile, a plurality of upper compartments 326 partitioned by upper grids 324 are formed inside the upper structure 320, and a plurality of upper compartments 326 partitioned by the lower grids 344 are formed inside the lower structure 340. A plurality of lower compartments 346 are formed.

The upper compartment 326 includes first upper compartments 326A and third upper compartments 326C adjacent to both sides 302 and 304 of the body 300, and adjacent first upper compartments 326A. And second upper compartments 326B disposed between the fields and the third upper compartments 326C, that is, at the center side of the upper compartment 326. In this case, the first upper compartments 326A are located outside the upper structure 320 and the third upper compartments 326C are located relatively inside the upper structure 320. Due to the curvature shape of both sides 302 and 304, the first upper compartment 326A and the third upper compartment 326C may be formed to have one side round, and the volume of the third upper compartment 326C is the most It is large, and the volume of the second upper compartment 326B is formed to be the smallest.

21 and 22 are views showing a part of the water solar panel installation structure according to another embodiment of the present invention. Here, FIG. 21 is a side view showing an enlarged portion of the floating solar panel installation structure, and FIG. 22 is a perspective view of the solar panel installation structure of FIG. 21.

In this embodiment, there is only a difference in some configurations of the solar panel installation structure, and in other configurations, since the configurations of the solar panel installation structures of FIGS. 1 to 16 are the same, hereinafter, characteristic parts of the present invention It will be explained mainly.

21 and 22, a solar panel with respect to a second square tube 144 on one side adjacent to the end of the solar panel support 146 of the solar panel support structure 140 according to an embodiment of the present invention A fixing frame 148 for fixing the support 146 is installed. The end of the solar panel support 146 having one side mounted on the fixed frame 148 is located at a position spaced upward by a predetermined distance d with respect to the second square tube 144, and the solar panel support ( The photovoltaic panel 160 installed at 146 is also positioned to be spaced upward with respect to the second square 144 by a separation distance d.

According to the present embodiment, in the process of installing and operating an aquatic solar panel installation structure on the water surface, the solar panel 160 is upward by a separation distance (d) with respect to the second square tube 144 forming a support surface. As it is spaced apart from each other, there is an advantage of suppressing the external force such as waves.

However, when the end of the solar panel 160 is disposed to be spaced apart by a separation distance d with respect to the second square tube 144, the support of the solar panel 160 to the solar panel installation structure 140 It can become unstable.

Therefore, the solar panel installation structure 140 according to the present embodiment further includes a triangular bracket 170 for stably supporting the end 161 of the solar panel 160 with respect to the second square 144 .

The triangular bracket 170 may have a substantially triangular cross-section in a vertical direction, and for example, the cross-section of the triangular bracket 170 may be a right triangle.

The triangular bracket 170 includes a support bracket body 171 formed of a plastic material that is light and resistant to corrosion, such as polyethylene or waste carbon fiber reinforced plastics, and supports The bracket body 171 has a first surface 172 that forms a lower edge of the support bracket body 171, and a front edge of the support bracket body 171, and a solar panel support 146 and a solar panel A second surface 173 on which the end of the 160 is supported, and a third surface 174 forming a rear edge of the support bracket body 171 are formed.

The first surface 172 has the largest area, the third surface 174 has the smallest area, and the area of the second surface 173 is larger than the area of the first surface 172 and the third surface 174 It is formed smaller than the area of ). That is, the first surface 172 having the largest area abuts on the second square 144 so that the samganghyuk bracket 170 can be supported with respect to the second square 144 more stably.

A portion of the second surface 173 is recessed by a predetermined depth and a recessed portion 177 on which the end of the solar panel support 146 and the solar panel 160 are seated is formed, and one end of the recessed portion 177 A first stopper portion 176 and a second stopper portion 178 are formed in which the end portions 161 of the solar panel 160 and the solar panel support 146 are respectively caught and the seating positions are maintained.

Further, fastening holes (not shown) are formed in the recessed part 177, and a fastening member passing through the solar panel support 146 and the solar panel 160 is fixed to the fastening holes, so that the solar panel ( 160) more stable support can be performed.

In addition, the end 161 of the solar panel 160 and the end of the photovoltaic panel support 146 are caught on the first stopper portion 176 and the second stopper portion 178 formed on one side of the depression 177 As a result, the solar panel 160 may be more firmly supported. In this embodiment, the end 161 of the solar panel 160 is formed to extend more than the end of the solar panel support 146, and the end 161 of the solar panel 160 and the solar panel 160 Some of the lower surfaces are seated and supported on the triangular support 170.

At this time, the depression depth of the depression 177 is formed larger than the sum of the thickness of the solar panel support 146 and the thickness of the solar panel 160, and the thickness of the solar panel support 146 and the solar panel ( It is formed smaller than twice the size of the sum of the thicknesses of 160).

In addition, the side of the triangular bracket body 171 is in a direction parallel to the plane in which the first side 172, the second side 173, and the third side 174 are formed, that is, a triangle toward the side of the triangular bracket body 171 Bracket side through-hole 175 is formed. The triangular bracket side through hole 175 is formed in a shape corresponding to the triangular bracket body 171, and may be formed in a reduced shape at a predetermined ratio with respect to the shape of the triangular bracket body 171.

The triangular bracket side through hole 175 is formed in a reduced shape with respect to the shape of the triangular bracket body 171, so that the first side 172, the second side 173, and the third side 174 are located in a triangle Since the thickness of the bracket body 171 is uniformly formed, there is an advantage that the load applied to the triangular bracket 170 can be properly distributed.

In addition, as a part of the triangular bracket 170 is formed through penetration, the weight may be reduced, and when an external force such as waves or wind is applied toward the side of the triangular bracket 170, the side of the triangular bracket 170 Without resisting the external force, the external force passes through the triangular bracket side through-hole 175, thereby increasing the stability against the external force.

In the above, preferred embodiments of the present invention have been described, but the present invention is not limited thereto, and various modifications can be made within the scope of the claims, the detailed description of the invention, and the accompanying drawings. It is natural to fall within the range.
