Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floating coupling structure in which a plurality of float solar photovoltaic devices are combined,

The present invention relates to a floating coupling structure to which a plurality of float solar photovoltaic devices are combined, and which can easily combine floating bodies of a plurality of float solar photovoltaic devices and generate waves (for example, The present invention relates to a floating coupling structure to which a plurality of float solar photovoltaic devices are coupled so as to stably maintain the state of engagement of the floating bodies with respect to the float.

The development and use of renewable energy is actively being done in conjunction with the energy problem. Among them, solar power generation is the most attracted to solar power generation because it is easy to install and operate, and it is possible to secure relatively stable power generation power, compared to other power generation methods using other energy, and the installation and operation proportion is also relatively large.

Such photovoltaic power generation is constituted based on a solar cell that receives solar light and generates electric power by a photoelectric effect, and a converter that converts generated electric power produced by the solar battery into AC power or converts it into direct DC power.

This photovoltaic power generation is relatively easy to install and operate compared to other power generation methods, but it can be installed quickly. However, since the amount of power generated is proportional to the installation area, it is inevitable to secure a site for installation and operation to be. However, it is not easy to secure sites that meet site conditions.

In order to avoid the difficulties and to secure the development site, the method of using the wall, roof and small scale of the building is used, and it is possible to secure some site. However, this also causes a difficulty in installing and designing a solar cell structure, resulting in an increase in the unit price of power generation, and the difficulty in maintenance due to the scarcity of a small power generation facility is increased. In order to solve this problem, it is being sought to install and operate water and marine facilities such as rivers, lakes and reservoirs.

It is anticipated that water and maritime space will be used as a farm or leisure space for only a part of the space.

However, contrary to this expectation, the fact that the photovoltaic power generation facilities are actually installed and operated in the waterfront and sea areas is very low. This is because solar power generation greatly changes in the amount of generated power due to factors such as variations in the incidence of sunlight, that is, changes in incident angle, generation of shadows such as clouds, and factors such as water or dust particles in the air. However, in the case of water or sea, there are many factors that inhibit the incident light amount of solar light on the ground surface, especially solar cell is fluctuated according to the waves of water surface or sea surface, and it is very difficult to maintain optimal generation amount. Further, it is assumed that a plurality of solar cell structures include the meaning of 'water' and 'sea' such as 'sleep', 'lake', 'river', 'reservoir' ) Is also a factor that makes operation of marine photovoltaic power generation difficult.

Particularly, in the case of floating solar power generation devices floating on the water surface, an external force due to natural phenomena such as waves of the surface of the sea surface or typhoons acts on the solar power generation device as compared with the ground-mounted solar power generation device, There has been a problem that the supporting body and the float must be firmly fixed to external forces due to natural phenomena such as wave or sea waves or typhoons.

Particularly, a method for fixing a plurality of float solar photovoltaic devices together at a mounting position more stably on the water surface is being sought.

To this end, a coupling structure of a plurality of floating solar power generation devices according to the related art is configured to be coupled to a plurality of floating bodies using a bracket or the like.

However, when a plurality of floating bodies are connected by a bracket or the like, the connecting means such as a bracket does not have any damping function for absorbing or canceling vibrations or external forces. Therefore, the external force such as waves or strong winds propagating along the water surface There has been a problem that the bracket is easily broken due to periodic stress applied to the bracket, and there is a problem that the connection of the coupling structure is easily released.

Further, in the case of connecting a plurality of floating bodies by using a bracket or the like, there is a difficulty in installing the bracket by fastening bolts and nuts or by performing riveting after mounting the bracket at the installation position.

Hereinafter, a method of coupling the floating bodies 200 in the floating coupling structure 2000 according to the present invention will be described in more detail with reference to the drawings.

FIG. 2 is a schematic perspective view of a coupled state of the floating body 200 according to an embodiment of the present invention, and FIG. 3 is a perspective view of a floating body 200 and a coupling member 500 according to an embodiment of the present invention. And FIGS. 4A and 4B are schematic longitudinal sectional views of the floating body 200 according to an embodiment of the present invention.

2, the floating body 200 according to the present invention includes a rail-shaped insertion groove 210, and two rail-shaped insertion grooves (not shown) of two floating bodies 200, 210 form an insertion space into which a coupling member 500 to be described later can be inserted while being in contact with each other, and the coupling member 500 has a rail shape of two floating bodies 200, And inserted into the insertion space formed by the insertion grooves 210, thereby coupling the two floating bodies 200. In this way, the other plurality of floating bodies 200 are coupled to each other by the rail-shaped insertion groove 210 and the coupling member 500 which is inserted in the rail-shaped insertion groove 210 in an insertion manner, Thereby forming a floating coupling structure 2000 to which the floating bodies 200 are coupled.

The coupling member 500 will be described in more detail later in the description of FIG. 4, although it will be described below.

The floating body 200 is formed in a rectangular parallelepiped shape having four side surfaces. This is to bring the side surfaces of the plurality of floating bodies 200 into contact with each other.

The floating body 200 has a square cross section. That is, the floating body 200 has a square shape with reference to a plan view. This makes it possible to manufacture the floating body 200 in the same shape irrespective of the position of the floating body 200 in the floating coupling structure 2000 so that the manufacturing speed and productivity of the floating body 200 can be improved have.

The floating body 200 includes a rail-shaped insertion groove 210 at each of four sides and a through-hole 230 having a predetermined width passing through the floating body 200.

The rail-shaped insertion groove 210 is formed to a predetermined depth in the thickness direction of the floating body 200 on all sides of the floating body 200.

Specifically, the rail-shaped insertion groove 210 is formed in a thickness direction from a top edge of the floating body 200 to a predetermined depth, and includes a first insertion portion 211 and a second insertion portion 213 .

The first inserting portion 211 is formed to be spaced a predetermined distance from the edge of the floating body 200 toward the center of the floating body 200 and is formed long in the lateral direction with a predetermined width w1 do. The first insertion portion 211 is a portion into which the floating body fixing portion 510 of the coupling member 500 to be described later is inserted.

The second inserting portion 213 is connected to the edge of the floating body 200 from the outer side of the first inserting portion 211 and has a width w1 smaller than the width w1 of the first inserting portion 211 w2. The second insertion portion 213 is a portion into which the intermediate connection portion 520 of the coupling member 500 to be described later is inserted.

In other words, the rail-shaped insertion groove 210 has a T shape as a whole when viewed from a plane view, and when the side surfaces of adjacent floating bodies 200 are in contact with each other, The rail-shaped insertion grooves 210 are in contact with each other to form an overall shape based on the plan view. As will be described later, the coupling member 500 has an overall shape based on the plan view corresponding to the shape of the rail-shaped insertion grooves 210 contacting with each other.

The width d of the first insertion portion 211 may be greater than the thickness t of the floating body fixing portion 510. In this case, As described below, the coupling member 500 is inserted into the rail-shaped insertion groove 210 in a state in which the compression elastic restoring force is applied to the coupling member 500, and the side surfaces of the adjacent floating body 200 are connected to each other So that the insertion of the coupling member 500 into the rail-shaped insertion groove 210 is facilitated and at the same time, an inner nut (not shown) for adjusting the overall length of the coupling member 500 531 and the outer nut 533 can be rotated.

The floating body 200 includes at least one positioning projection 250 projecting in a hemispherical shape on each side and at least one positioning groove 250 having a shape and size corresponding to the positioning projection .

2 to 4B, the floating body 200 includes the positioning protrusions on both sides of the rail-shaped insertion groove 210 at the upper portion of one side surface thereof, The rail-shaped insertion groove 210 is provided at the lower portion with the positioning groove 250 on both sides of the rail-shaped insertion groove 210, and on the opposite side of the other side, And the positioning protrusions 240 are provided on both sides of the rail-shaped insertion groove 210 at a lower portion of the other side surface.

4A, the positioning protrusions 240 and the positioning grooves 250 are engaged with each other. When the plurality of the floating bodies 200 are engaged with each other, The alignment protrusions 240 and the positioning recesses 250 can be easily aligned with each other so that the engaging operation can be facilitated The coupling force concentrated on the coupling member 500 is relaxed because the coupling member 500 is constrained to the lateral (i.e., lateral) departure from the adjacent floating bodies 200 and restrains to a predetermined range with respect to the vertical direction The coupling force of the whole of the plurality of floating bodies 200 can be improved while improving the life of the coupling member 500.

4B, when the floating bodies 200 swing up and down against external forces such as waves (e.g., waves) or strong winds propagating to the water surface, due to the nature of hemispherical shape, The floating body 200 can be prevented from being detached from the floating coupling structure 2000 since the floating body 200 can be guided to the horizontal position of the floating body 200 again after vibrating up and down within a predetermined range, Can be stably maintained. As a result, breakage of the floating body 200 due to dislocation can be prevented, and the maintenance cost can be reduced.

A wire groove 260 accommodating a certain portion of the wire w is provided along the longitudinal direction of the floating body 200 on all sides of each of the plurality of floating bodies 200. This is because the external force such as a wave (for example, a wave or the like) propagating to the water surface as a groove in which the wire w surrounding the entire side surface of the floating coupling structure 2000 is accommodated The wire w can be prevented from being detached from the side surface of the floating body 200 even if it acts on the coupling structure 2000 and the coupling force of the floating coupling structure 2000 can be further improved.

The floating body 200 has a through opening 230 configured to penetrate the upper surface and the lower surface of the floating body 200. The through openings 230 are configured to have a predetermined area (i.e., a predetermined surface area). The plurality of penetrating openings 230 may be provided in the floating body 200.

The floating body 200 of the floating solar cell 1000 according to the related art is not provided with the penetrating opening 230 and can transmit the water waves transmitted along the water surface without being reduced, The floating state of the floating body 200 can not be stabilized and the entire floating body 200 covers the entire surface of the water so that there is no oxygen supply area in the water surface and water located in the lower part of the floating body 200, There is a problem that if the floating body 200 is installed in a considerably large number on the water surface, serious water pollution is caused.

However, as shown in FIG. 2, since the floating body 200 of the floating solar power generation apparatus 1000 according to the present invention has the through-hole opening, the surface wave transmitted along the water surface is reduced at the through-hole The floating state of the floating body 200 can be continuously stabilized and at the same time, even if several floating units 200 are provided on the water surface, the oxygen supply area can be secured in the water surface and water through the through openings, .

That is, due to the penetration opening 230, the present invention can reduce the wave resistance of the water surface acting as an external force on the floating body 200, thereby stabilizing the floating state of the floating body 200, It is possible to increase the exposed surface area of the water surface for exposing the water surface to the atmosphere so as to be in contact with the atmosphere, thereby preventing water contamination due to insufficient oxygen supply to the water surface.

5 is a schematic exploded perspective view of a coupling member 500 according to an embodiment of the present invention.

5, the coupling member 500 includes two rail-shaped insertion grooves 210 which are provided in two floating bodies 200 adjacent to each other among the plurality of floating bodies 200 and are arranged to face each other, So that the two floating bodies 200 are connected to each other.

A handle 513 is provided on the upper portion of the floating body fixing portion 510. Therefore, the worker can more easily and safely carry out the process of inserting the floating body fixing portion 510 into the rail-shaped insertion groove 210.

A frictional force increasing portion 515 is provided on one side of the floating body fixing portion 510, which is positioned near the intermediate connecting portion (i.e., on the inner side in both surfaces). By providing the frictional force increasing portion 515 in this way, the one side surface presses the rail-shaped insertion groove, and the frictional force between the floating body fixing portion and the rail-shaped insertion groove is significantly increased due to the frictional force increasing portion. It is possible to prevent the floating body fixing portion from being detached from the rail-shaped insertion groove when an external force is applied.

Preferably, the frictional force increasing portion 515 may be formed of a rubber pad. By constituting the frictional force increasing portion with the rubber pad, it is possible to prevent the floating body fixing portion from being detached from the rail-shaped insertion groove, while at the same time, shock and impact are buffered between one side of the floating body fixing portion and the rail- It is possible to prevent the main body fixing portion and / or the rail-shaped insertion groove from being damaged from each other.
