As shown in the drawings, an aquatic photovoltaic power generation system in which a buoyancy member and a frame are integrated according to the present invention is characterized in that when the buoyancy member 10 and the frame 20 are integrally connected and the support 1 and the supports 1 are connected A connecting member 3 for providing a passage, and a solar panel 5 for generating solar light to be irradiated.

The buoyancy member 10 provides buoyancy that allows it to float in water (i.e., to the aquifer).

The buoyancy member 10 includes a foam layer 11 to be foam molded and a coating layer 13 coated on the outer surface of the foam layer 13 to be coated.

The foam layer 11 is made of foamed polystyrene (EPS) foam or foamed urethane foam which is light in weight and excellent in buoyancy. The coating layer 13 is made of an external polyurea resin or polyurea which is eco-friendly and excellent in durability, Is made of mixed hybrid resin.

The material of the foam layer 11 is preferably polystyrene or polyurethane which is excellent in buoyancy and relatively inexpensive.

The foamed polystyrene has various densities ranging from high density to low density depending on the density and the compressive strength. However, considering the volume-to-volume buoyancy, the expanded polystyrene has a density of 10 to 30 kg / m 3 and a compressive strength of 4 to 16 N / Polystyrene is suitable.

The polyurea resin as the coating layer 13 is excellent in properties such as durability, impact resistance, abrasion resistance, adhesion, water resistance, heat resistance, cold resistance, corrosion resistance, tensile strength and tear strength. This polyurea resin 13 is coated on the surface of a foamed foam or a foamed foam with the foamed layer 11 by a high pressure spray coating method to form a protective film integrated with the surface to thereby break the foamed foam 11 into foamed foam or urethane foam And the lifetime can be increased.

In addition, a coating layer of a hybrid resin in which a polyurea resin or polyurea and polyurethane are mixed with a coating layer 13 having excellent durability such as impact resistance, abrasion resistance, etc. may be damaged from external shock to the foam layer 11 by styrofoam or urethane foam, The life of the buoyancy member 10 can be remarkably increased. In addition, the foam layer 11 separated from the buoyancy member 10 can prevent serious marine pollution and damage to the ecosystem caused by the foamed styrofoam or urethane foam pieces.

Since the hybrid resin in which the polyurea resin or the polyurea and the polyurethane are mixed with the coating layer 13 is excellent in water resistance, the polyurea coating layer blocks moisture from penetrating the foamed layer 11 into the foamed foam or the urethane foam, It is possible to use semi-permanently without decreasing the buoyancy due to moisture penetration, and the polyurea coating layer is elastic and smooth, so that the attached organisms can not be easily fixed.

The hybrid resin in which the polyurea resin or polyurea and polyurethane are mixed with the coating layer (13) is resistant to ultraviolet rays and prevents contraction or expansion due to a change in temperature of solar heat and season.

A ventilation hole 17 is formed in the buoyancy member 10 so as to cool the solar panel 5 in which the cold air passing through the ventilation hole 17 is disposed thereon so as not to lower the power generation efficiency, Also serves to reduce the shaking of the support 1 by the wings of the water phase.

The frame 20 fixes the buoyancy member 10, and the solar panel 5 is mounted thereon.

It is not an easy task to connect the frame 20 and the buoyancy member 10 to each other so that the frames 20 are stably installed. Thus, in assembling the photovoltaic power generation apparatus to the watercraft, the combination of the frame 20 and the buoyancy member 10 requires much time, manpower, and cost.

In order to solve such a problem, the present invention is a method for manufacturing a support (1) in which a frame (20) and a buoyancy member (10) So that installation time and installation cost are significantly reduced.

The buoyancy member 10 and the frame 20 are integrally formed in the buoyancy member 10 so that the buoyancy member 10 and the frame 20 are integrated with each other so that the body 21 and the vertical bar 22, (1).

As a method of embedding the frame 20 in the buoyancy member 10, the styrofoam 11 of the buoyancy member 10 is foamed, and the frame 20 is inserted into the mold for foaming, 11) is foamed to produce an insert. Such an insert method is advantageous in that the buoyancy member 10 and the frame 20 are strongly and intermittently engaged with each other, however, it is troublesome to insert the frame 20 into the mold for foaming and the mold becomes complicated and occupies a large space .

As another method for embedding the frame 20 in the buoyancy member 10, the buoyancy member 10 may be formed as a powder 10A or 10B having a groove structure 19 in which the frame 20 can be embedded And bonding the powders 10A and 10B to each other using an adhesive.

For example, when two frames 20 are embedded in one buoyancy member 10 as shown in the figure, the buoyancy member 10 is made of three powders of the center powder 10A and the two side powder 10B, A contact agent is applied to the inner surfaces of the three powders (i.e., the middle powder and the two side powder), and the frame 20 is embedded in the groove structure 19 formed on the inner surface of the fine powder, 10 so that the frame 20 is embedded.

As another method of embedding the frame 20 in the buoyancy member 10, a plurality of through holes are formed in the buoyancy member 10, and a through hole of the buoyancy member 10 is formed in the through- The frame 20 is embedded in the buoyancy member 10 by passing the vertical bar 22 of the frame 20 through another through hole and assembling the same to the built-in body 21 There is an assembly method.

That is, the buoyancy member is provided with a horizontal through hole (not shown) in the horizontal direction and two vertical through holes (not shown) vertically connected to the inside through the horizontal through hole, And the vertical bar 22 is inserted into the two vertical through holes and assembled to the body 21.

At this time, a hollow pipe is inserted into each of the horizontal through holes and the vertical through holes, an adhesive is applied to the outer surface of the hollow pipe to adhere to the buoyancy members forming the horizontal through holes and the inner surfaces of the vertical through holes, The body may be inserted into and inserted into the hollow pipe of the horizontal through hole, and the vertical bar may be inserted into the hollow pipe of the two vertical through holes before being assembled to the body.

It is to be noted that the frame 20 is embedded by the insert method and the bonding method is the styrofoam 11 of the buoyancy member 10 and the styrofoam 11 is embedded in the frame 20 by the insert method or the bonding method The primer is applied to the surface of the styrofoam 11 and then the polyurea resin 13 is applied on the surface of the styrofoam 11 so that the bonding clearance between the styrofoam 11 and the frame 20 is sealed by the polyurea resin 13.

The frame 20 includes a body 21, vertical bars 22 vertically connected to both front and rear sides of the body 21, a solar panel 5 coupled to the upper portion of the vertical bar 22, As shown in FIG.

The hinge plate 211 is provided on both front and rear sides of the body 21 so that the connector 3 is hinged. The hinge plate 211 protrudes from the outer surface of the buoyancy member 10.

The vertical bars 22 are vertically connected to both front and rear sides of the upper surface of the body 21, respectively. The solar panel 5 has to be obliquely arranged so that the amount of daylight is large. Thus, the two vertical bars 22 have different protrusion lengths. That is, the rear vertical bar 22 is longer than the front vertical bar 22, and the solar panel 5 mounted on the two vertical bars 22 is inclined so as to descend toward the front side.

The profile 23 connects two vertical bars 22 provided on the front and rear sides of the body 21, and a solar panel 5 is mounted thereon.

The inclination angle of the solar panel 5, which increases the amount of sunshine depending on the season, is changed. That is, it is preferable that the angle of the solar panel 5 can be adjusted in order to increase the power generation efficiency by increasing the amount of sunshine.

A length adjusting block 24 is coupled to the vertical bar 22 and a hinge bracket 25 is coupled to the profile 23 to adjust the angle of the solar panel 5.

The vertical bar 22 has a hollow 221 formed therein and a length adjusting portion 241 inserted into the hollow 221 of the vertical bar 22 is formed at a lower portion of the length adjusting block 24, A plurality of length adjusting holes 243 are formed in the length adjusting portion 241 and a plurality of length adjusting holes 243 are formed in the length adjusting portion 241. The length adjusting holes 243 are formed in the fixing holes 223, In the hole 243, the length of the length adjusting block 24, through which the adjusting pin 26 is inserted and fixed, is adjusted to protrude above the vertical bar 22.

A hinge hole 245 is formed at an upper portion of the length adjusting block 24 and a hinge bracket 25 hinged to the hinge hole 245 by a hinge pin 27 is formed at a lower portion of the profile 23 So that there is no obstacle to connecting the profile 23 even if the projecting length of the length adjusting block 24 is changed.

When the length of the protrusion of the length adjusting block 24 is adjusted, the distance between the two vertical bars 22 is also changed so that the position of the hinge bracket 25 in the profile 23 is adjusted. In order to easily adjust the position of the hinge bracket 25, a slit groove 231 is formed on the outer surface of the profile 23 in the longitudinal direction. The slit groove 231 receives the head of the bolt 28 and allows the pin portion of the bolt 28 to pass therethrough so that the bolt 28 can freely adjust its position in the slit groove 231. The pin portion of the bolt 28 passes through the hinge bracket 25 and is then fastened with a nut to fix the hinge bracket 25 at that position. That is, the head and nut of the bolt are tightened and the hinge bracket 25 is pressed and fixed to the propane therebetween.

A mounting bracket 29 for mounting the solar panel 5 is coupled to the profile 23.

The mounting bracket 29 can also be easily positioned in the profile 23 like the hinge bracket 25. In other words, a slit groove 231 is formed in the upper portion of the profile 23, and a bolt, in which the head is freely movably inserted into the slit groove 231, is fixed by fastening the mounting bracket 29.

The mounting bracket 29 includes a vertical portion 291 having a length corresponding to the thickness of the solar panel 5 and a first portion 291 horizontally connected to the lower portion of the vertical portion 291, And a second horizontal portion 295 horizontally connected to the upper portion of the vertical portion 291 to cover the upper portion of the solar panel 5. The second horizontal portion 295 is moved along the vertical portion 291 to adjust the position thereof so as to pressurize and fix the surface of the solar panel 5 and to prevent damage to the solar panel 5 to be pressed It may be desirable to have a rubber pad on the contact surface.

The support 1 composed of the buoyancy member 10 and the frame 20 can float on its own in the water phase, but the stability is weak.

Thus, the supports 1 are connected to each other through the connecting body 3 to increase the stability, and the connecting bodies 3 are connected to each other to form a passage through which the worker can pass.

The supporting body 1 is connected to both sides of the connecting body 3 in the longitudinal direction, and another connecting body 3 is connected to both sides in the left and right direction.

The surface of the water changes with the weather. In other words, the support 1 and the connecting body 3 floating in the water are shaken sometimes weakly and sometimes strongly by the wave, and are also shaken by the load of the worker passing over the connecting body 3. The degree and direction of this fluctuation varies from point to point.

Therefore, when the connecting body 3 and the supporting body 1 are fixedly connected, the load due to the swinging tends to be concentrated at the connecting portion and is likely to be broken. Therefore, it is preferable that the connecting body 3 and the supporting body 1 are fluidly connected to some extent Do.

Thus, the link body 3 and the support body 1 are hinged so as to be fluidly connected.

A hinge plate 211 is provided on the body 21 of the frame 20 of the support body 1 for hinge coupling and hinge plates 211 of the support body 1 are provided on both sides of the connector body 3 in the front- And a hinge pin 33 is inserted through the hinge plate 211 and the hinge plate 31 so that the hinge plate 31 and the hinge plate 31 are hinged to each other in the horizontal direction. At this time, if the hinge plate 211 or the hinge plate 31 is rotatably coupled to the supporting body 1 or the connecting body 3, fluidity can be increased.

A hinge plate 211 and a hinge plate 31 are provided on both side surfaces of the connecting body 3 in the right and left direction so that the connecting bodies 3 arranged in the left and right longitudinal direction are hinged to each other.

It is preferable that holes 35 are formed in the connecting body 3 so as to penetrate the connecting body 3 in the vertical direction so that snow, dirt, and the like are not accumulated thereon.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention has been described with respect to a solar photovoltaic power generation system in which a bumpy member having a specific shape and structure and a frame are integrated, Such variations and modifications are to be construed as falling within the scope of protection of the present invention.
