It is about a buoyancy assembly.

As pollution of the natural environment is worsening, much research is being conducted on the development of eco-friendly power generation facilities that can generate electricity using eco-friendly energy, and more specifically, solar power generation, wind power generation, geothermal power generation, etc. Research is being conducted to go beyond the level of obtaining a small amount of electricity and to replace the electricity produced by conventional power generation facilities.

In this regard, solar power generation facilities have been widely spread in recent years, but there is a disadvantage that the solar power generation facilities must be installed on a large scale in order to supplement the electric energy obtained through existing power generation means through the solar power generation facilities. , there is a problem that a large flat area is needed for this.

This solar power generation has the advantage of being relatively easy to install and operate and can be installed quickly compared to other power generation methods. However, since the power generation amount is proportional to the installation area, securing a site for installation and operation is essential to secure the desired power generation amount. am. However, it is not easy to secure a site that meets the location conditions.

Accordingly, in order to secure power generation sites, plans are being explored to install them in water and sea areas such as rivers, lakes, and reservoirs.

Since only a portion of water and marine space is used as a fish farm or leisure space, it is expected that a vast area of land can be secured as an operating space for power generation facilities compared to land land.

Typically, floating solar power generation facilities are formed with a certain thickness and a large area, and are made by installing a plurality of solar power modules at equal intervals on a barge that can float on the water surface by connecting a plurality of floats with supports.

Since the above-described buoyancy member or buoyancy body has a structure with an empty internal space, there is a problem in that when an external force is applied and the buoyancy body is damaged, water seeps into the buoyancy member through the damaged area.

In addition, there is a problem that the solar power generation device may be corroded as seawater flows into the floating solar power generation device due to waves or swells.

Hereinafter, a barge using a buoyancy assembly according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

1 to 7 show a barge using a buoyancy assembly according to the first embodiment of the present invention. Referring to the drawing, a barge using a buoyancy assembly according to the first embodiment of the present invention includes a plurality of buoyancy assemblies 100 arranged along the front, left, and right sides, a frame 110 connecting the buoyancy assemblies 100 to each other, and , and is provided with a deck portion 120 installed on the frame.

The frame 110 includes a plurality of first connection members 111 that integrally connect a plurality of buoyancy assemblies 100 arranged left and right, and a plurality of first connection members 111 arranged front and rear. It includes two second connection members 112.

The first connection member 111 is an H beam extending left and right. A plurality of first connection members 111 are arranged along the front-back direction. The first connection members 111 are arranged to be spaced apart from each other.

The first connecting member 111 is bolted to the covers of the plurality of buoyancy assemblies 100 arranged along the left and right directions. The buoyancy assembly 100 is installed to be spaced apart at regular intervals along the longitudinal direction of the first connecting member 111.

The second connecting member 112 is an H beam extending forward and backward. The second connecting member 112 is coupled to the first connecting members 111 above the first connecting members 112 to integrally connect them.

Unlike this embodiment, the first and second connecting members 111 and 112 may be made of square wood, pipes, or channels.

The deck portion 120 is installed on the frame 110 and includes a deck plate 121 with a drain hole 122 through which water can drain, and allows water on the deck plate 121 to drain, but is resistant to swells or waves. It includes an inflow prevention portion 130 installed in the drain hole 122 to prevent water bouncing from below from flowing onto the deck plate 121.

The deck plate 121 is formed in a rectangular plate shape. The deck plate 121 is disposed above the second connecting member 112 and is coupled to the second connecting member 112. The deck plate 121 may be made of one wide plate-shaped member or may be made of a plurality of plate-shaped members arranged front, back, left and right on the second connecting member 112.

The deck plate 121 is formed with a drain hole 122 penetrating along the vertical direction. A plurality of drain holes 122 are formed along the width and length directions of the deck plate 121. The deck plate 121 is supported by the buoyancy assembly 100 floating on the water to support cargo or personnel on the water or provides an area where a floating solar power generation device (not shown) can be installed.

In addition, it is preferable that a guard rail 150 is installed on the frame 110 or the deck plate 121 to cover the upper area of the deck plate 121 formed on the deck plate 121 from the side.

The guard rail 150 prevents cargo or personnel supported by the deck plate 121 from being separated from the deck plate 121 when the deck plate 121 is tilted by waves or swells.

The inflow prevention portion 130 includes a first inflow prevention film 131 that protrudes from the inner peripheral surface of the drain hole 122 in the direction of blocking the drain hole 122 and forms a first outflow hole 132 that is smaller than the drain hole 122, It is provided with a second inflow prevention film 133 that protrudes from the inner peripheral surface of the drain hole 122 to form a second outflow hole 134 that is arranged to be alternate with the first outlet hole 131 and is smaller than the drain hole 122.

The first and second inflow prevention films 131 and 133 may be formed integrally with the deck plate 121.

The first inflow prevention film 131 is formed to protrude from one inner peripheral surface of the drain hole 122. The first inflow prevention film 131 is formed in a plate shape that closes a portion of the drain hole 122.

The first outflow hole 132 is formed at the end of the first inflow prevention film 131.

The second inflow prevention film 133 is formed to protrude from the inner peripheral surface of the other side of the drain hole 122. The second inflow prevention film 133 is formed below the first inflow prevention film 131. The second inflow prevention film 133 is formed in a plate shape to close a portion of the drain hole 122 below the first inflow prevention film 131. The second inflow prevention film 133 is formed parallel to the first inflow prevention film 131.

The second outflow hole 134 is formed at the end of the second inflow prevention film 133. The second outflow hole 134 is covered on its upper side by the first inflow prevention film 131.

The first and second inflow prevention films 131 and 133 form a zigzag flow path in the drain hole 122 in the vertical direction.

This deck portion 120 allows water or seawater accumulated on the deck plate 121 due to rain or waves to flow out downward through the drain hole 122. At this time, the water or seawater flowing into the drain hole 122 sequentially passes through the first outlet hole 132 and the second outlet hole 134 and is drained downward from the deck plate 121.

Alternatively, when seawater bounces upward toward the deck plate 121 due to waves or swells, it is primarily blocked by the second inflow prevention membranes 131 and 133 to prevent it from flowing onto the deck plate 121. At this time, a portion of the seawater bouncing toward the deck plate 121 may flow into the drain hole 122 through the second outlet hole 134. In this situation, since the first inflow prevention membrane 131 covers the upper part of the second outflow hole 134, seawater passing through the second outflow hole 134 collides with the first inflow prevention membrane 131. Seawater passing through the second outlet hole 134 collides with the first inflow prevention membrane 131, loses kinetic energy, and can no longer pass through the drain hole 122.

The seawater that collides with the first inflow prevention membrane 131 is discharged downward again through the second outlet hole 134 due to its own weight.

The inflow prevention unit may be configured with a different structure.

Figure 9 shows another embodiment of the inflow prevention unit 140.

Referring to the drawing, the inflow prevention part 140 of a barge using a buoyancy assembly according to another embodiment of the present invention is formed on the inner peripheral surface of the drain hole 122 and is capable of flowing up and down so that seawater on the deck plate 121 flows through the drain hole 122. ) When seawater flows into the drain hole 122 from below, each end is provided with inflow prevention pieces 141 that come into contact with each other and block the drain hole 122.

The inflow prevention pieces 141 extend from the inner peripheral surfaces of one side and the other side of the drain hole 122 facing each other to close the drain hole 122 and face each other.

The inflow prevention pieces 141 extend obliquely downward at the same inclination relative to the horizontal. One end of the inflow prevention piece 141 is made of a material having elasticity that can move up and down. The inflow prevention piece 141 may be made of the same synthetic resin material as the deck plate 121 and may have a structure formed of a sufficiently thin thickness to enable elastic deformation. Additionally, the inflow prevention piece 141 may be formed of a separate rubber material attached to the inner surface of the drain hole 122.

The inflow prevention pieces 141 extend to a length where one end of each side comes into contact with each other. At this time, the sum of the extended lengths of the inflow prevention pieces 141 in contact with each other is formed to be larger than the diameter of the drain hole 122.

The inflow prevention pieces 141 are formed to have a thinner thickness at the other end adjacent to the inner peripheral surface of the drain hole 122, so that one end can easily flow up and down.

For this purpose, it is preferable that the inflow prevention pieces 141 have an inlet groove 143 formed on the lower surface of the other end adjacent to the inner peripheral surface of the drain hole 122 to facilitate the flow of the inflow prevention pieces 141.

The inlet groove 143 is formed to extend long along the width direction of the inlet prevention pieces 142.

A contact plate 142 is formed at one end of each of the inflow prevention pieces 141 to expand the surfaces in contact with each other.

The contact plate 142 extends downward from the end of the hydraulic pressure prevention piece 141. The contact plate 142 is formed in a plate shape integral with the inflow prevention piece 142.

When seawater accumulated on the deck plate 121 flows into the drain hole 122, the inflow prevention pieces 141 flow due to the load of the seawater, and the contact plates 142 in contact with each other are spread.

As the contact plates 142 open, the drain hole opens and the seawater in the drain hole 122 drains downward.

And when the seawater below the deck plate 121 bounces upward due to waves or swells, the bounced seawater interferes with the inflow prevention pieces 141 and is blocked from passing through the drain hole 122.

At this time, the inflow prevention pieces 141 that block the drain hole 122 effectively block seawater from flowing onto the deck plate 121 by improving airtightness by bringing each contact plate 142 into contact with each other.

Hereinafter, the buoyancy assembly 100 will be described in detail with reference to FIGS. 3 to 7.

The buoyancy assembly 100 includes a main body 10, a cover 30, a plurality of buoyancy bodies 40, a fixture 50, and a sealing portion.

In addition, a locking protrusion coupled to the lower end of the coupling flange portion 15 is further provided at the bottom of the coupling skirt portion 35. The locking protrusion extends a certain length from the bottom of the coupling skirt portion 35 toward the body portion or coupling flange portion 15. The locking protrusion 53 is coupled to the coupling skirt portion 35 to add a fixing force for fixing the cover 30 to the main body 10 together with the fixture 50.

The main body 10 and the cover 30 according to the present invention may be formed of the same material. For example, the main body 10 and the cover 30 may be made of polyethylene.

Differently, the main body 10 and the cover 30 can be formed of different materials, and polypropylene, polyurethane, steel, aluminum, fiber-reinforced composite, etc. can be used.

The buoyancy bodies 40 are arranged adjacent to each other along the front, left, and right directions within the accommodation space 12. The buoyancy body 40 has a buoyancy space 41 formed therein to provide buoyancy.

The buoyancy body 40 is formed in a hexahedral structure having a front side (40A), a back side (40B), a left side (40C), a right side (40D), an upper side (40E), and a lower side (40F).

A first reinforcement portion 42 is provided on the side of the buoyancy body 40 to prevent the buoyancy body 40 from being deformed when an external force acts on the buoyancy body 40.

The first reinforcement portion 42 has a structure formed on the front side 40A and the back side 40B, which are disposed to face both sides of the main body 10 in the longitudinal direction. In addition, in this embodiment, the first reinforcement portion 42 is formed with three first reinforcement portions 42 spaced apart from each other at regular intervals on the front side 40A and the rear side 40B of the buoyancy body 40.

The first reinforcement portion 42 is inserted from the side of the buoyancy body 40 toward the inside of the buoyancy body 40 at a certain depth to form a groove structure. The first reinforcement portion 42 extends along the longitudinal or width direction of the buoyancy body 40.

Within the accommodation space 12, a plurality of buoyancy bodies 40 are disposed along the front, rear, left and right sides, and thus a first buoyancy hole 42a is formed between the first reinforcement parts 42 adjacent to each other. The first buoyancy hole 42a is formed as a cylindrical space.

The first and second reinforcement parts 42 and 46 have a structure inserted into the buoyancy body 40 to increase the rigidity or resistance to bending stress of the buoyancy body 40 itself. The second reinforcement portion 46 effectively prevents the buoyancy body 40 from being distorted or damaged due to external force or impact applied to the buoyancy body 40.

In addition, between adjacent buoyancy bodies 40, a first buoyancy tube is installed inserted into the first buoyancy hole 42a to occupy the first buoyancy hole 42a and provides buoyancy between the buoyancy bodies 40. (43) is further provided. The first buoyancy tube 43 can be formed of a material that can expand and contract. The first buoyancy tube 43 is formed in a cylindrical shape identical to the shape of the first buoyancy hole 42a.

The first buoyancy tube 43 not only provides buoyancy between the buoyancy bodies 40, but is also interposed between adjacent buoyancy bodies 40 to support the buoyancy bodies 40 spaced apart at small intervals, thereby (buoyancy body) 40) It prevents the surfaces facing each other from being worn or damaged by friction. In addition, the first buoyancy tube 43 is interposed between the buoyancy bodies 40 and has a buffering effect to block shock or external force from being transmitted from the buoyancy body 40 on one side to the buoyancy body 40 on the other side. can do.

A second buoyancy tube inserted into the second buoyancy hole is further provided between the buoyancy body 40 and the inner surface of the main body 10.

The second buoyancy tube 43 is made of a material that can expand and contract. The second buoyancy tube is formed in a cylindrical shape with a semicircular cross section identical to the shape of the second buoyancy hole.

The second buoyancy tube 43 provides buoyancy between the inner surface of the main body 10 and the buoyancy body 40, and also allows the buoyancy body 40 to be spaced apart from the inner surfaces of the main body 10 at a fine interval. By supporting, the buoyancy body 40 flows due to external shock and is partially prevented from being worn or damaged due to friction with the inner surface of the main body 10.

Additionally, the third buoyancy tube 47 may act as a buffer to block shock applied from the outside of the buoyancy assembly 100 from being transmitted to the buoyancy body 40.

Meanwhile, Figure 8 shows a buoyancy body 40 according to another embodiment of the present invention. Referring to the drawings, the buoyancy body 40 of the buoyancy structure may have an embossed portion 45 formed on the side. The embossed portion 45 is formed to protrude outward on the left side 40C of one side of the buoyancy body 40 and the right side 40D of the other side buoyancy body 40, respectively, facing the inner peripheral surfaces on both sides in the width direction of the main body 10. .

The embossed portion 45 is formed to protrude from the side surface of the buoyancy body 40 in a semicircular shape.

The embossed portion 45 forms a space between the main body 10 and the buoyancy body and between the buoyancy bodies 40. The embossing portion 45 prevents the buoyancy body 40 from being worn by friction by reducing the contact area between the main body 10 and the buoyancy body 40 and the contact area between the buoyancy bodies 40. In addition, the embossing portion 45 cushions the shock transmitted to the buoyancy body 40 applied to the buoyancy assembly 100 from the outside.

The embossed portion 45 may be formed integrally with the buoyancy body 40. Alternatively, the embossed portion 45 can be formed separately from the buoyancy body 40 and then attached to the buoyancy body 40. When the embossing portion 45 is formed separately from the buoyancy body 40, the buoyancy body 40 is made of a rubber material with elasticity so that it can be elastically supported against the main body 10 or another buoyancy body 40. It can be formed by attaching formed members.

Returning to FIGS. 3 to 7, the buoyancy body 40 is preferably molded and formed by a blow molding method.

By molding the buoyancy body 40 using a blow molding method, it can be made lightweight, has a certain amount of elasticity, and can provide high buoyancy by forming a buoyancy space 41 inside.

The fixture 50 includes a plurality of hook pins 51 that pass through the main body 10 and the cover 30 to secure the cover 30 to the main body 10.

The hook pin 51 includes a head portion 51A, an extension portion 51B, and a locking piece 51C.

The head portion 51A has a circular cross-section and is formed with a larger diameter than the first through hole 18 and the second through hole 32. The head portion 51A contacts the upper surface 40E of the plate portion 31 to limit the depth at which the extension portion 51B is retracted.

The extension portion 51B protrudes downward for a certain length from the lower surface 40F of the head portion 51A so that it can pass through the first through hole 18 and the second through hole 32. The extension portion 51B is formed to be divided and divided into a plurality of parts based on the center of the axis so that the diameter can be varied.

The lower part of the extension portion 51B is located at the head portion 51A to minimize interference and jamming of the catching piece 51C, which will be described later, when passing through the first through hole 18 and the second through hole 32. It is formed in a tapered structure whose diameter gradually decreases as it extends downward.

The extension portion 51B has elasticity so that it can be compressed in the direction of the central axis or returned to its original state. The extension portion 51B may be hollow on the inside to reduce weight and save materials.

The locking piece 51C protrudes from the extension portion 51B in a direction perpendicular to the axial direction and comes into contact with the lower end of the vertical portion 17. The lower part of the catching piece 51C is inclined to minimize jamming when passing through the first through hole 18 and the second through hole 32.

When connecting the main body 10 and the cover 30 using the hook pin 51 as described above, the hook pin 51 has an extension portion 51B that forms the first through hole 18 and the second through hole 18. While being inserted into (32), it is retracted and passes through the first through hole (18) and the second through hole (32) in a state in which the diameter is reduced, and the locking piece (51C) completely passes through the second through hole (32). When it does so, it opens back to its original state due to elasticity and the upper end of the locking piece (51C) is caught at the lower end of the horizontal portion (16). In this state, separation of the hook pin 51 from the first through hole 18 and the second through hole 32 is restricted and suppressed.

The watertight member 71 may be made of the same material as the plate portion 31, or may be made of an elastic material such as rubber to increase watertightness.

Additionally, differently from this, a packing part formed of an elastic material such as rubber may be coupled to at least one side of the end of the watertight member 71 or the bottom of the watertight groove 13 to increase the watertightness of the sealing part.

The watertight member 71 has a width smaller than the width of the watertight groove 13, and its lower end is in close contact with the bottom of the watertight groove 13 to block water from entering the receiving space 12.

Although not shown in the drawing, an outwardly extending discharge hole (not shown) may be formed at the bottom of the watertight groove 13 so that water flowing into the watertight groove 13 can be discharged.

Meanwhile, the cover 30 of the buoyancy assembly according to the present invention protrudes upward from the plate portion 31 to protect the head portion 51A of the fixture 50 exposed above the plate portion 31. A head protection part surrounding the part 51A may be further provided.

Referring to FIG. 8, the head protection part 37 is fastened to the upper part of the plate part 31 with the hook pin 51 passing through the first through hole 18 and the second through hole 32. It is formed in a cylindrical shape to surround the side of the protruding head portion 51A.

As shown, the head protection portion 37 protrudes to a height equal to or higher than the height of the head portion 51A to protect the head portion 51A from impact or external force.

In the barge using the buoyancy assembly according to the present invention as described above, the buoyancy body 40 is inserted and arranged to occupy the receiving space 12 provided inside the main body 10, resulting in cracks or damage to the main body 10. Even if water flows into the receiving space (12) through the part, the buoyancy is maintained constant by the buoyancy body (40), so there is no problem such as the floating solar power generation device sinking into the water or leaning to one side. can be stably supported, and through this, stable power generation of the floating solar power generation device can be promoted.

In addition, the barge using the buoyancy structure according to the present invention can discharge seawater on the deck plate 121 through the drain hole 122, and seawater bouncing from the bottom of the deck plate 121 is blocked by the inflow prevention unit 130. This has the advantage of preventing corrosion of the floating solar power generation device.
