Description

Buoyancy for Solar Module Structure

The present invention relates to a buoyancy body for an aquatic solar module, and more specifically, a hollow part is provided inside the outer skin, and a hollow part is formed inside the upper half and the outer skin in which a coupling part for coupling the structural frame is formed on the upper surface. It relates to a buoyancy body for an aquatic solar module in which the lower half to be provided is coupled by thermal fusion, and a fusion line formed by thermal fusion is formed above the height center of the buoyancy body.

In recent years, as interest in eco-friendly energy increases, the use of solar power generation is more active, and such solar power generation is generally generated by forming a structural frame on the ground and installing a solar module on the top. On the other hand, due to the nature of the narrow downtown area, most of the solar modules are installed on top of buildings or structures, and recently, solar power generation in the concept of solar farm is also being made on suburban land, but the storage and efficient transmission of the produced energy is There is a difficult limit.

In order to overcome the limitations of the above ground and promote power generation efficiency, efforts are being made to actively perform power generation by forming a structure for a photovoltaic module on the water surface and mounting the photovoltaic module. Typically, a floating solar module is provided with a buoyant body (buoy) floating on the water, and is mounted by installing a structure on the top of the buoyant body.

However, conventional buoyancy bodies were generally made of styrofoam materials, but in recent years, as a problem of environmental pollution has emerged, by injection molding so that a hollow part is provided inside using a synthetic resin material, the buoyancy body that generates buoyancy is actively used. It is being produced.

Since the buoyant body made of synthetic resin material produced through such injection molding is produced by heat-sealing the divided pieces together, there is a limit to the possibility of breakage in the fusion line joined by heat-sealing. As water flows into the hollow part between the pieces, there is a problem that the original function as a buoyancy body is completely lost.

As a prior art document related to this, there is Korean Patent Registration No. 1990541 "Rich" (registered on June 12, 2019, hereinafter referred to as "prior art document"). The prior art document is structurally simple by forming a convex portion and a concave portion at the edge formed at the end of each half body to melt the convex portion and flow into the concave portion during heat fusion in bonding a pair of divided half bodies to each other by heat fusion. We propose a rich man who can withstand the wave force well because the bonding strength is secured.

However, in the prior art document, the fusion line is located at the center of the height of the father, as a pair of half bodies formed in a symmetrical shape is formed, and when the fusion line is damaged by an external force such as wave force, the water line is the fusion line. Since it is provided at a location corresponding to (half of the buoyancy is designed to be twice the required self-weight), water easily flows into the hollow part and thus the buoyancy is lost.

In addition, the conventional buoyancy bodies including the prior art documents have a structurally weak problem when the lift force is generated by wind pressure, and there is a limit in that the power generation efficiency of the solar module decreases as the structure itself rotates by the wind pressure. In order to solve this problem, a separate binding wire is sometimes provided, but construction is cumbersome and the air is inevitably longer.

Furthermore, there is an additional problem in that the position is moved along the flow of the water by receiving resistance by the shape of the buoyant body when the flow is generated on the water surface by wind.

The present invention was devised to solve the above problems, and the fusion line of the half body is located above the water line to prevent rapid flooding even if damage occurs, and to secure buoyancy for a long time, and to prevent resistance due to the flow of running water. It is an object of the present invention to provide a buoyant body for an aquatic solar module capable of minimizing and stably constraining the structure to the correct position and preventing the structure from being turned or rotated by wind pressure.

In order to solve the above problems, the buoyancy body (B) supporting the structural frame (F) for installing the aquatic solar module of the present invention is entirely surrounded by the outer skin portion 110 and the hollow portion 120 therein Is provided, the lower part is opened to form the lower opening part 130, and the upper half body in which the coupling part 140 for coupling the structural frame F is formed on the upper surface 111 of the outer skin part 110 ( 100); And a lower half body 200 that is entirely surrounded by the outer skin 210 and provided with a hollow part 220 therein, and the upper part is opened to form an upper opening part 230. The outer skin portions 110 and 210 of the half body 100 and 200 are formed to have a streamlined horizontal and vertical cross section of the side surfaces 112 and 212, and the outer skin portion 110 of the upper half body 100 The upper end of the outer skin 210 of the lower half and the lower half 200 are combined by heat fusion, and the fusion line 300 formed by heat fusion is formed above the height center (C) of the combined buoyancy body (B), The outermost protrusion in the vertical cross section of the outer skin portion 110, 210, side surface 112, and 212 is formed below the fusion line 300 and formed on the side surface 212 of the lower half body 200, and the lower portion At least one vertical plate 250 is formed to protrude downward on the bottom surface 211 of the outer skin 210 of the half body 200.

According to the buoyancy body for a floating photovoltaic module of the present invention, even if the fusion line of the half body is located above the water line, even if damage occurs, the inflow of water is blocked, so that rapid flooding can be prevented.

In addition, a plurality of partition walls are formed in the hollow portion of the half body, so that even if damage occurs, water inflow is blocked for a certain period of time, so that buoyancy can be secured for a long time.

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the accompanying drawings.

1 shows a photovoltaic power generation structure having a buoyant body (B) for an aquatic solar module according to an embodiment of the present invention, wherein a plurality of frames (F) are supported by the buoyancy body (B). It shows the shape provided on the water in a state, Figure 2 is a perspective view showing in detail the buoyancy body (B) according to an embodiment of the present invention.

As shown in FIG. 2, the buoyancy body (B) is composed of an upper half body 100 and a lower half body 200, and is preferably formed by injecting a synthetic resin material. At this time, as shown in FIG. 3, the upper half body 100 is entirely surrounded by the outer skin portion 110 and a hollow portion 120 is provided therein to secure buoyancy. However, the lower portion of the outer skin portion 110 is opened to form a lower opening portion 130, and a coupling portion 140 is formed on the upper surface 111 of the outer skin portion 110 to form a power generation structure (F) is combined to float in the water by the buoyancy body (B) of the present design.

In addition, the lower half body 200 is entirely surrounded by the outer skin 210 so that a hollow part 220 is provided therein to ensure buoyancy, and the upper part is opened to form an upper opening part 230.

On the other hand, the lower half of the outer skin 110 of the upper half 100 and the upper end of the outer skin 210 of the lower half 200 are bonded to each other by thermal fusion. Accordingly, since the hollow portion 120 of the upper half body 100 and the hollow portion 220 of the lower half body 200 are tightly blocked, buoyancy can be stably secured.

In general, as the buoyancy body is manufactured by a heat-sealing method, taking a symmetrical structure has the advantage of saving production cost and improving workability. In this case, in the completed buoyancy body, the fusion line formed by thermal fusion is located at the center of the height.

However, since the buoyancy is usually designed to be twice the required self-weight in manufacturing the buoyant body, under the premise that the half body is formed in a symmetrical shape, the water line is located at the center of the height of the buoyant body because half the fusion line is formed. For this reason, when damage occurs due to wave power in the fusion line, which is structurally weak, water flows into the hollow part, thereby losing buoyancy, which is its natural function.

Accordingly, the buoyancy body (B) of the present invention is formed by heat-sealing the ends of the upper and lower halves (100, 200), and the fusion line 300 is higher than the height center (C) of the combined buoyancy body (B). The upper half body 100 and the lower half body 200 are made asymmetrically so that they are formed, and the height of the upper half body 100 is formed to be lower than the height of the lower half body 200. 300) is located relatively higher than the height center (C).

As a result, even if some damage occurs in the fusion line 300 formed by heat fusion of the upper half and the lower half, the inflow of water is blocked, so that the loss of the structure due to the rapid submersion of the floating body B can be prevented in advance.

Meanwhile, a plurality of partition walls 221 may be formed in the hollow portion 220 of the lower half body 200, and a plurality of compartments 222 may be provided by the partition walls 221. The partition wall 221 may adopt a general shape arranged in a horizontal or vertical direction so as to have a lattice shape, but it is preferable to make it more structurally robust by adopting a curved shape or a honeycomb shape.

The partition wall 221 performs a function of reinforcing the hollow portion 220 of the lower half body 200, which is structurally weak, and at the same time, damage occurs in the fusion line 300, so that even if a partial flooding phenomenon occurs, By preferentially allowing water to flow into only the adjacent compartment 222, the time for water to flow into the damaged floating body B can be delayed to the maximum.

To this end, the partition wall 221 provided in the hollow part 220 is provided with a compartment 222 along the outer periphery, and an additional compartment 222 is provided inside the outer periphery. This inflow time can be further delayed.

In particular, a plurality of partition walls 121 are formed in a shape corresponding to the partition wall 221 formed in the lower half body 200 in the hollow portion 120 of the upper half body 100 that is heat-sealed to the lower half body 200. By being formed, a plurality of compartments 122 may be provided by the partition walls 121.

By forming the partition walls 221 and 121 in a shape corresponding to both the lower half 200 and the upper half 100, the compartments 222 and 122 can be integrally formed in a state completely blocked from the adjacent compartments. Therefore, even if a breakage occurs, since water flows only into the compartments 122 and 222 of the breakage, loss of buoyancy can be prevented. Therefore, there is an advantage that the buoyancy body (B) can be used permanently by removing water from the compartments 122 and 222 into which water has flowed and repairing the damaged area.

Meanwhile, as shown in FIG. 4(a), the outer skins 110 and 210 of the upper and lower half bodies 100 and 200 are formed so that the horizontal cross section of the side surfaces 112 and 212 has a streamlined shape. Can be. As the side surfaces 112 and 212 of the upper half 100 and the lower half 200 are manufactured to have a streamlined shape, the buoyancy body ( By preventing B) from moving out of position along the flow, the structure can be stably constrained in position.

In addition, as illustrated in FIG. 4A, the side surfaces 112 and 212 may be formed to have a streamlined cross-sectional view in the vertical direction. Accordingly, even if a wave is generated on the water surface, the buoyant body B has the effect of stably receiving the wave flow without being overturned or largely flowed by the wave.

On the other hand, the conventional buoyancy bodies have a structurally weak problem when the lift force is generated by wind pressure, and there is a limit in that the power generation efficiency of the solar module decreases as the structure itself rotates by the wind pressure.

Inevitably, conventional structures having a buoyant body have a limitation in that they have no choice but to have a separate binding wire in order to stably bind the structure to the lift force caused by wind power.

Accordingly, the buoyancy body (B) for an aquatic solar module of the present invention is formed by protruding outward a pair of horizontal wings 240 on the side 212 of the outer skin 210 of the lower half 200, which is submerged in water, Even if lift is generated in the buoyancy body B, the horizontal wing 240 is located in a state submerged in the lower part of the water surface, so that the buoyancy body B can provide a fixing force to resist lift based on the water pressure. . In addition, the pair of horizontal wings 240 also serves to balance the buoyancy body (B) to stably float from the irregular flow of the water surface.

Meanwhile, as shown in FIGS. 6A and 6B, at least one vertical plate 250 may be formed to protrude downward on the bottom surface 211 of the outer skin 210 of the lower half 200. The vertical plate 250 functions to prevent rotation based on resistance to water so that the buoyant body B is prevented from rotating due to the wind pressure even when the wind pressure acts, so that the solar module can be disposed in a desired direction.

The buoyancy body (B) for an aquatic solar module according to the present invention described above is to be implemented in other specific forms without changing the technical idea or essential features of the present invention by those of ordinary skill in the technical field to which the present invention belongs. You will understand that you can.

Therefore, the embodiments described above are illustrative in all respects and should be understood as not limiting, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description described above, and the meaning and scope of the claims and All changes or modified forms derived from the equivalent concept should be interpreted as being included in the scope of the present invention.
