FLOATING APPARATUS FOR INSTALLATING SOLAR CELL PANEL FOR SOLAR PANELS

The present invention relates to a buoyant body for installing a solar cell panel. More particularly, the present invention relates to a solar cell panel for an aquarium solar power generation capable of effectively preventing buoyancy loss of a buoyant body and enhancing the durability of a structure by preventing external force such as algae, wind, .

Recently, global warming is accelerating due to air pollution caused by excessive use of fossil fuels such as petroleum, and various alternate energy is being studied to prepare for depletion of fossil fuels.

One of these alternative energies is solar technology using solar cells.

A solar cell is a photovoltaic cell designed to convert solar energy into electrical energy. It is a semiconductor device that converts light energy generated from the sun into electrical energy. When light is irradiated on a solar cell, electrons and holes are generated by light energy (photons). In p-type semiconductors, many carriers are holes and minor carriers are electrons, so that the difference in density formed due to electrons and holes generated by light (photons) undergoes a more rapid change in the case of electrons and vice versa in n-type semiconductors . When the electrons and holes diffuse to the periphery due to the density difference and reach the p-n junction where the potential difference is formed, the separation occurs due to the strong electric field. The electrons diffused from the p-type semiconductor migrate toward the n-type semiconductor, and the holes diffused from the n-type semiconductor migrate toward the p-type semiconductor and the current flows.

Such solar power generation has various advantages such as prevention of environmental pollution, but there is a limit that a large installation area is required to produce a required amount of electric power because the electric power generation amount depends on the amount of sunshine and the power generation efficiency is relatively low.

In order to overcome these limitations of photovoltaic power generation technology, aquatic photovoltaic technologies are being developed, in which power generation devices such as lakes, dams, reservoirs, rivers, and oceans are installed with a high amount of sunshine and few restrictions on the installation area.

As a conventional solar photovoltaic power generation technology, Korean Patent Registration No. 10-0936597 (Patent Document 1) proposes a solar water internal surface solar panel device in which a solar cell panel is installed on a solar cell frame that can float on the surface of a water such as a lake In Korean Patent Laid-Open Publication No. 10-2012-0026924 (Patent Document 2), a power generating support is buoyant to the surface of a river, a lake, a reservoir, a sea, a dam, and the like, And a power generation means for storing the energy converted into energy is installed.

However, the conventional technologies for aquatic photovoltaic power generation including the patent documents 1 and 2 have the following problems.

First, there is a problem in that buoyancy is lost due to permeation of water into the buoyant body over time. In reality, the loss of such buoyancy often causes solar PV structures to go below the surface of the water, and this is a serious problem considering the fact that PV facilities are quite expensive.

Second, buoyancy bodies installed in the aqueducts are bonded to each other in close contact with each other, so that external forces such as algae and wind are concentrated to the entire buoyant structure, and thus the durability of the structure There is a problem that it is rapidly weakened.

Third, since the weight of the buoyant body itself is large, there is a problem that it is difficult to provide sufficient buoyancy to the structure in a state where the solar battery panel is installed on the buoyant body.

Fourth, since the structure of the buoyant body is complicated, there is a problem in that time and cost efficiency for installation and maintenance is low.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing a buoyant body, that is, a buoyant body for installing a solar cell panel according to an embodiment of the present invention, a structure in which a plurality of buoyant bodies are interconnected will be described with reference to FIG.

Referring to FIG. 1, there is disclosed an arrangement structure in which buoyant bodies for interconnecting solar panels according to an embodiment of the present invention are connected to each other. Each buoyant body 1 is connected through a linear connecting member 2 . The linear connecting member 2 functions to connect the adjacent buoyant bodies to each other and to provide fluidity to the buoyant bodies by spacing the connected buoyant bodies at a predetermined distance. For example, the linear connecting member 2 may be composed of a metal chain or a rope.

Connecting buoyancy bodies with this structure has the following effects.

For the aquatic power generation, the buoyant bodies installed on the aqueduct receive external forces such as algae and wind. If a large number of buoyant bodies are combined in close contact, the external force is concentrated and transferred to the entire buoyant structure , There arises a problem that the durability of the structure is weakened.

However, according to the structure proposed by the present invention, since each buoyant body is connected by a linear connecting member 2 such as a metal chain with a certain distance, the buoyant body 1 corresponds to the length of the linear connecting member And the like. Because of this fluidity, the durability of the buoyancy structure for photovoltaic power generation is maintained for a considerable period of time, as compared with the conventional case, since the external force is not concentrated on the entire structure but dispersed in each buoyancy body 1 It is effective.

Hereinafter, the buoyant body 1 as a unit constituting the entire buoyant structure will be described.

FIG. 2 is an exploded perspective view of a buoyant body for installing a solar cell panel according to an embodiment of the present invention, FIG. 3 is an exploded perspective view of a portion where buoyant pipes are interconnected, which is a main part of an embodiment of the present invention, FIG. 4 is a plan view of FIG. 2, FIG. 5 is a cross-sectional view in AA 'direction of FIG. 4, and FIG. 6 is a cross-sectional view of a buoyancy pipe.

2 to 6, a buoyant body 1 for installing a solar cell panel according to an embodiment of the present invention includes a buoyancy providing unit 10 and a coupling unit 20.

The buoyancy providing unit 10 includes buoyancy pipes 11, 12, 13, and 14 filled with a waterproof buoyant material 111 therein.

For example, the materials of the buoyancy pipes 11, 12, 13 and 14 may be polyethylene (PE) or thermosetting reinforced plastic (FRP). Polyethylene is advantageous in light weight and low cost, and thermosetting reinforced plastic is a plastic composite material reinforced with glass and carbon fiber and is suitable as a lightweight structural material because of its excellent light weight, corrosion resistance and moldability. The specific gravity of FRP is about 2.0, about 1/4 of that of steel material, and the weight of FRP reinforced with carbon fiber (CF) is about 1.5, so it is lighter. In addition to the above, polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC), polyvinyl chloride (PVC) 14). ≪ / RTI >

For example, the buoyancy providing unit 10 may be configured to include four buoyancy pipes 11, 12, 13, and 14 arranged in a rectangular shape. Of these buoyancy pipes 11, 12, 13, and 14, adjacent buoyancy pipes are connected to each other by a coupling portion 20 described later. These buoyancy pipes 11, 12, 13 and 14 are referred to as a first buoyancy pipe 11, a second buoyancy pipe 12, a third buoyancy pipe 13 and a fourth buoyancy pipe 14. These four buoyancy pipes 11, 12, 13, 14 are substantially identical in structure and function. Therefore, in the following description, the first buoyancy pipe 11 is referred to as a reference and the second buoyancy pipe 12 adjacent to the first buoyancy pipe 11 is cited as necessary in order to avoid redundant description. .

Two through hole pairs penetrating the buoyancy pipe 11 vertically are formed near both ends of the buoyancy pipe 11. 6, through-hole pairs are formed near the left and right ends of the buoyancy pipe 11, respectively. With reference to the left end, reference numerals 112-1 and 112-2 denote upper Holes 113-1 and 113-2 are lower through-holes. As will be described later, coupling bolts are inserted and fastened to the pair of through holes, respectively. In the pair of through holes 112-1 and 113-1, coupling bolts 213-1 are inserted and fastened, And the coupling bolt 213-2 is inserted and fastened to the pair of through holes made of -2 and 113-2.

For example, the waterproof buoyant material 111 to be filled in the buoyancy pipe 11 may be configured to include expanded polystyrene. The foamed polystyrene which may be referred to as styrofoam is not only light but also excellent in water resistance and waterproofness so that the buoyant force of the buoyant body 1 can be increased and even if water penetrates into the buoyant pipe 11, The buoyancy is not lowered.

For example, in the inside of the buoyancy pipe 11, a damage preventive member 118 for preventing the waterproof buoyant member 111 from being damaged by contact with the buoyancy material connection bolt 114 is connected to the waterproof buoyant material 111 Bolts 114, as shown in FIG. Since the one surface of the damage preventing member 118 is in contact with the waterproof buoyant member 111 and the other surface of the damage preventing member 118 is in contact with the buoyancy connecting bolt 114, And is prevented from coming off and being supported by the buoyancy body connecting bolt 114. [

4, an example of a fastening structure between the buoyancy body connecting bolt 114 and the buoyancy pipe 11 will be described as follows.

4, a pair of holes (not shown) for fastening the buoyancy body connecting bolts 114 are formed in the buoyancy pipe 11, and the buoyancy body connecting bolts 114 penetrate these holes Respectively. Although not shown, nuts and packing members are additionally used for fastening the buoyancy pipe 11 and the buoyancy coupling bolt 114. [ The linear connecting member 2 is connected to the outer end region of the buoyant body connecting bolt 114. For example, when the linear linking member 2 is a metal chain, the linear linking member 2 may be welded to the end region of the buoyancy linking bolt 114.

For example, both ends of the buoyancy pipe 11 may be configured so as to be combined with the moisture permeation prevention members 116 and 117 for preventing the penetration of moisture into the buoyancy pipe 11.

The coupling unit 20 connects the four buoyancy pipes 11, 12, 13 and 14 included in the buoyancy providing unit 10 to each other to fix the buoyancy providing unit 10 so as not to be deformed by an external force, And four connection / securing means 21, 22, 23, 24 for providing a base on which the panel is installed. The structure and function of these four connecting / fixing means 21, 22, 23, 24 are the same. Therefore, the following description will be made with reference to the first connection / securing means 21 connecting the first buoyancy pipe 11 and the second buoyancy pipe 12 in order to avoid duplication of unnecessary description.

3 and 6, for example, the connecting / securing means 21 includes an upper plate member 211, a lower plate member 212, coupling bolts 213-1 and 213-2, The upper packing members 214-1 and 214-2, the lower nuts 215-1 and 215-2, the upper packing members 216-1 and 216-2, the lower packing members 217-1 and 217-2, (218-1, 218-2) and lower washers (219-1, 219-2).

The upper plate-shaped member 211 is disposed on the upper portion of the buoyancy pipe 11 and has upper fastening holes 211-1 and 211-2 opposing the upper fastening holes 112-1 and 112-2 formed in the buoyancy pipe 11, -2) are formed. An upper fastening hole not designated by the reference numeral in the upper plate-like member 211 is an upper fastening hole opposed to an upper through hole (not shown) formed in the second buoyancy pipe 12.

For example, the upper plate-shaped member 211 and the lower plate-shaped member 212, which will be described later, may be configured to have a triangular or rectangular shape or a "B" shape in a plane thereof, and the material thereof may be made of a metal material .

The lower plate-shaped member 212 is disposed at a lower portion of the buoyancy pipe 11 and has lower fitting holes 212-1 and 212-2 opposed to lower through holes 113-1 and 113-2 formed in the buoyancy pipe 11, -2) are formed.

The coupling bolt 213-1 is coupled through the upper through hole 112-1, the upper fastening hole 211-1, the lower fastening hole 113-1, and the lower fastening hole 212-1.

The upper nut 214-1 is fastened to an upper bolt region protruding from the upper surface of the upper plate-

The lower nut 215-1 is fastened to the lower region of the bolt protruding from the lower surface of the lower plate-shaped member 212. [

The upper packing member 216-1 has an elastic material and is partially inserted into the upper through hole 112-1 or coupled with the upper plate member 211 and the buoyancy pipe 11 interposed therebetween . The upper packing member 216-1 functions to prevent moisture penetration into the upper through hole 112-1.

The lower packing member 217-1 has an elastic material and is partially inserted into the lower through hole 113-1 or coupled with the lower plate member 212 and the buoyancy pipe 11 interposed therebetween . The lower packing member 217-1 functions to prevent moisture penetration into the lower through hole 113-1.

The upper washer 218-1 is provided between the upper plate member 211 and the upper nut 214-1 and prevents the upper nut 214-1 from being loosened due to weakening of the fastening force.

The lower washer 219-1 is provided between the lower plate member 212 and the lower nut 215-1 to prevent the lower nut 215-1 from being unwound due to weakening of the fastening force.

Since the fastening structure of the fastening bolt 213-2 is substantially the same as the fastening structure of the fastening bolt 213-1, a repetitive description will be omitted.

As described above in detail, according to the present invention, it is possible to effectively prevent the buoyancy loss of the buoyancy body provided with the solar cell panel for the aquaporized solar power generation, and to reduce the weight of the buoyant body.

Further, the unit buoyancy members are connected to each other through a linear connecting member while being spaced apart from each other by a predetermined distance, fluidity corresponding to the length of the linear connecting member is provided to the unit buoyancy members, It is possible to prevent the external force from concentrating on the entire buoyant structure and to enhance the durability of the structure.
