It is a method that stores electricity in a capacitor and uses it independently from the power supply source, and is mainly used in mountainous areas where there are no telephone poles.

In addition, in order to install the solar panel, an installation space of a certain area is required, and the solar panel must be arranged at a certain angle facing the sun to maximize the power generation efficiency of the solar panel. To this end, a frame and fixing means are provided so that the solar panel is fixed in a state arranged at a certain angle. Here, the conventional frame and fixing means are mainly made of metal such as high-strength iron to provide support to the solar panel.

However, conventional frames and fixing means for supporting and fixing solar panels are exposed to a high humidity environment due to rain for a long period of time, and corrosion occurs, resulting in a decrease in supporting power and deterioration of the solar panels. there was.

In addition, when the solar panel is installed in a marine environment, corrosion of metals such as iron by chloride ions contained in seawater is promoted, so that the durability of salt damage is significantly reduced.

These fiber-reinforced plastics have reduced material cost, light weight, and easy processing compared to metal materials, but are excellent in strength, durability, impact resistance, and abrasion resistance, and are excellent in corrosion resistance and are not rusted. In addition, the fiber-reinforced plastic is a material that combines nylon fibers such as glass fiber, carbon fiber, and Kevlar, and thermosetting resins such as unsaturated polyester and epoxy resin. When the unsaturated polyester is heated, it is entangled in a three-dimensional network shape through reaction. It hardens to a physically and chemically stable state. Here, the fiber reinforced plastic is preferably understood as a concept encompassing carbon fiber reinforced plastic and glass fiber reinforced plastic. At this time, the glass fiber-reinforced plastic material uses a plurality of glass fibers obtained by melt-processing glass containing silicate as a reinforcing agent, and has heat resistance and chemical durability, so corrosion is prevented, and not only has strong tensile strength, but also has insulation.

Therefore, unlike a conventional metal frame, the pull-out buoyant body 51 and the base frame part 60 of the fiber-reinforced plastic-coupled buoyancy body 50 are pultruded as fiber-reinforced plastic material through a pultrusion molding machine (not shown). Therefore, even when exposed to a marine environment with a high proportion of moisture and chloride ions for a long period of time, corrosion does not occur and the production cost is low while providing a solid support, and corrosion resistance and economy can be remarkably improved.

Moreover, the pull-out buoyancy body 51 of the fiber-reinforced plastic binding buoyancy body 50 is manufactured in a hollow shape, and the base frame portion 60 is manufactured with a minimized thickness, so that the weight is reduced and the occurrence of cracks is minimized. It can be improved.

Here, the fiber-reinforced plastic binding buoyancy body 50 preferably includes a pull-out buoyancy body 51, a watertight cover 52, and a curable resin 53.

At this time, it is preferable that the pull-out buoyancy body 51 is pull-molded as a fiber-reinforced plastic material in a hollow shape with both ends open and the circumference closed. In addition, in some cases, the pull-out buoyancy body 51 is fitted in the longitudinal direction from the inner ends of both ends of the pull-out buoyancy body 51 to the outer side in the longitudinal direction so as to be inserted into the slit groove 52c to be described later (not shown) May be extended integrally. Accordingly, when the watertight cover is coupled to both ends of the pull-out buoyancy body pultruded with fiber-reinforced plastic, the expansion protrusion and the insertion protrusion and the insertion protrusion are intersected in multiple stages along the radial direction, and a curable resin is interposed therebetween. With a structure that is filled and hardened, the watertightness and support of the fiber-reinforced plastic bonded buoyant body can be remarkably improved.

That is, it is preferable that the buoyancy space (f) is formed in the inside of the pull-out buoyancy body 51 and the watertight cover 52 coupled to each other.

Here, it is preferable that the total amount of buoyancy provided by the buoyancy space (f) inside the fiber-reinforced plastic bonded buoyancy body 50 exceeds the total weight of the floating solar cell device 200. For example, when the total weight of the floating solar cell device 200 is 320KG, it may be provided so that the total amount of buoyancy by the fiber-reinforced plastic binding buoyancy body 50 is 655KG.

Moreover, since each component of the floating solar cell device 200 is manufactured and combined with fiber-reinforced plastic or engineering plastic, which is a lightweight material, not metal as in the prior art, it is required for floating on the water even when installed in a marine environment. The resulting buoyancy can be reduced and economic feasibility can be improved.

In addition, it is preferable that the inner protrusion 52b extends integrally in the longitudinal direction along the circumferential direction from the inner end of the cover body 52a so as to fit into the inner circumferential profile of the pull-out buoyancy body 51. At this time, it is preferable that the outer diameter of the inner insertion protrusion 52b is formed to substantially correspond to the inner diameter of the pull-out buoyancy body 51.

Moreover, the length of the inner protrusion 52b in the longitudinal direction may extend to a length different from the length of the expansion protrusion 52d in the longitudinal direction so as to improve water tightness. That is, as the positions of the longitudinal ends of the interpolation protrusion 52b and the expansion protrusion 52d are formed to be different from each other, the protrusions may be formed in multiple stages along the radial direction, but may be staggered so that the lengths of the longitudinal ends are different. have.

Through this, when the pull-out buoyancy body 51 and the watertight cover 52 are coupled together, the expansion protrusion 52d and the interpolation protrusion 52b are joined in multiple stages along the radial direction, so that watertightness can be significantly improved. have.

Moreover, since a pair of watertight covers 52 cover and support both ends of the pull-out buoyancy body 51, the shape of the pull-out buoyancy body 51 can be firmly supported even with external forces such as wave force.

On the other hand, the curable resin 53 is preferably hardened by being filled between the pull-out buoyancy body 51 and the watertight cover 52. At this time, the curable resin 53 is most preferably provided with an epoxy resin.
