The suspension assembly 10 'may adopt a plurality of suspension assemblies 10' according to the installation area of the solar power generator 400. In this embodiment, the 20 suspension assemblies are divided into two first and second space portions 20) 30 are formed.

The solar power generator 400 includes a solar module 410 having a plurality of solar panels and support frames 420 and 430 supporting the solar modules 410.

3, the floating assembly 10 'includes a float 11 floated in the water phase, a metal plate 12 mounted on the float 11 and supporting the body weight of the operator, A first angle 13 provided along the vertical edge of the float 11 and a second angle 14 provided along the horizontal edge of the upper side of the float 11, A plurality of side plates 16 connected between the second angle 14 and the third angle 15 and supporting the side of the float 11, .

The float 11 supports the solar power generator 40 while floating in the sea, a river, a lake or a reservoir. The float 11 is in the form of a box having a rectangular parallelepiped as a whole. The float 11 preferably has a size of 180 cm long, 90 cm long, Or 135 cm in width, 70 cm in height, and 60 cm in height. The float 11 is preferably made of styrofoam or urethane foam which floats well in water and has excellent chemical resistance.

On the surface of the float 11, a strength reinforcing layer 11a made of a resin, for example, a polyurea coating film, is formed to improve corrosion resistance and strength. This strength reinforcing layer 11a has excellent mechanical properties, thereby preventing the float 11 from being broken in a severe aquatic environment.

The metal plate 12 is provided with a check plate or a lattice-type wire net on the upper side in which a plurality of protrusions 12a for preventing slippage are formed in a check form. The metal plate 12 is provided with a work space for an operator to install or manage the solar power generator 400. At this time, a plurality of projections or lattice grids 12a are formed to generate frictional force with the shoe so as not to slip during the work .

The first angle 13 reinforces the vertical edge side of the float 11 by wrapping the longitudinal side edge of the float 11. It is preferable that the first angle 13 is an angle whose cross section is "a ".

The second angle 14 is located along the edge of the upper side of the float 11. At this time, the second angle 14 has a second horizontal end 14a which is in close contact with the upper corner side surface of the float 11 and a second vertical end 14b which is bent at the second horizontal end 14a, And a plurality of fastening holes h1 are formed in the second vertical end 14b.

The third angle 15 is located along the edge of the lower end side of the float 11. The third angle 15 includes a third horizontal end 15a which is in close contact with the bottom edge side surface of the float 11 and a third vertical end 15b which is bent at the third horizontal end 15a, And a plurality of fastening holes h2 are formed in the third vertical end 15b.

That is, the first, second, and third angles 13, 14, and 15 are coupled in a hexahedron along the edge of the float 11 to reinforce the float 11. At this time, the first, second and third angles 13, 14 and 15 are interconnected by fastening various types of clamps or clamps with fastening members such as bolts B and nuts.

The side plate 16 is connected between the second angle 14 and the third angle 15 to support the side surface of the float 11. The side plates 16 are connected to the second and third horizontal ends 14b and 15b of the second and third angles 14 and 15 by fastening members B and N such as bolts and nuts Thereby reinforcing the side surface of float 11 again.

With the above structure, the floating assembly 10 and the other floating assembly 10 'are coupled to each other by the fastening member B (N). That is, in a state in which the suspension assembly 10 and the other suspension assembly 10 'are in close contact with each other, as shown in FIG. 4, the second and third vertical ends 14b and 15b of one suspension assembly The bolts B pass through the fastening holes h1 and h2 formed in the second and third vertical ends 14b 'and 15b' of the floating assembly and then the nut N is fastened to the bolt B, A number of suspension assemblies 10, 10 'can be coupled together without welding.

The first and second space portions 20 and 30 are formed on the inner side of the floating structure 100 as shown in FIG. 2 and are completely blocked from the outside of the floating structure 100. Water filled in the first and second space portions 20 and 30 causes the water filled in the first and second space portions 20 and 30 to be repelled when the floating structure 100 moves due to wind or storm So as to minimize the movement (fluctuation) of the floating structure 100. That is, the water filled in the first and second space portions 20 and 30 acts as a brake to prevent the floating structure 100 from moving. Accordingly, the photovoltaic device 400 installed in the floating structure 100 can maintain a stable position. Furthermore, since the movement of the floating structure 100 can be minimized, the configuration for fixing the floating floating station to the water phase can be simplified, and the installation cost and effort can be reduced.

1 and 5, the photovoltaic module 410 is located on the upper side of the first and second space portions 20 and 30 in the photovoltaic device 400 described above. Accordingly, the water filled in the first and second space portions 20 and 30 is spouted or evaporated to cool the solar cell module 410, thereby increasing solar power generation efficiency.

In general, due to the characteristic of the light module, the conversion efficiency decreases when the temperature rises. When the temperature rises 30 degrees from the reference temperature (15 ° C), the light conversion efficiency is reduced by about 11%. However, in the present invention, since the solar module 410 is located on the upper side of the first and second space parts 20 and 30, the water is splashed or evaporated in the first and second space parts 20 and 30, It is possible to prevent the solar module 410 from being cooled down, thereby lowering the power generation efficiency.

The first connection support bars 200 and 200 'and the second connection support bars 300 and 300' are for rigidly positioning the floating assembly 10 and 10 'coupled to each other. Since the water floating station of the present application is installed in the waterfront, the assembled state of the boo assembly 10 ', 10' and the spatial structures 40, 50 can be weakened by the wind. In particular, the floating suspension assembly 10 (10 ') and the spatial structure 40 (50) must be very tightly coupled, especially since the floating suspension station is installed on the airstream and is very difficult to maneuver and difficult for an operator to access. To this end, the first connecting support bars 200 and 200 and the second connecting supporting bars 300 and 300 'rigidly couple a plurality of float assemblies 10 and 10' in the transverse and longitudinal directions .

The first connecting support bars 200 and 200 'and the second connecting supporting bars 300 and 300' are angles of the 'A' shape and are formed of various types of brackets, clamps, fastening members B and N, 15 and the second and third angles 14,

At this time, a clamp C for fastening the first and second connection supporting bars to each other is installed at a portion where the first connecting supporting bars 200, 200 'and the second connecting supporting bars 300, 300' do. The clamp C includes first and second connecting supporting bars 200, 200 ', 300 (300', 300 ', 300', 300 ', 300' ) 300 ', it is possible to complete a robust floating suspension station capable of withstanding wind and storm surges.

As such, according to the present invention, the float assembly 10, 10 'and the spatial structures 40, 50 are configured such that the float 11 is located at the first, third, and third angles 13, 14, It is possible to increase the structural durability to maintain the box shape even though it generates large buoyancy. Therefore, it is possible to implement the floating structure 100 having a large installation area by connecting the plurality of suspension assemblies 10 and 10 'and the spatial structures 40 and 50 firmly in the lateral direction and the longitudinal direction, The solar cell generator 400 may be installed in the structure 100 to enable large-scale photovoltaic generation in the aquarium.

Also, since the floating assembly 10 and the other floating assembly 10 'and the spatial structures 40 and 50 can be connected to each other by using bolts and nuts without welding, it is possible to easily construct a non-welded structure.

Further, by forming the first and second space portions 20 and 30, it is possible to minimize the movement (rocking) even when the wind or the storm is severe, and the configuration for fixing the floating station can be simplified, Effort can be reduced.

Since the solar module 410 is located on the upper side of the first and second space portions 20 and 30 so that the water filled in the first and second space portions 20 and 30 is splashed or evaporated, It is possible to cool the solar cell 410, thereby preventing the solar power generation efficiency from being lowered.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
