JP, 2018-16288, A

In the float aggregate as disclosed in Patent Document 1, the float on the outer periphery of the float aggregate may be used as a passage without installing a solar panel. Such floats may invert as the waves pass through the float.

Provided is a float aggregate which is filled with a filler and which is arranged at a position facing an outer periphery of the aggregate surrounding the float aggregate.

In the float aggregate of the present invention, the filled float in which at least a part of the hollow portion is filled with the filler is arranged on the outer periphery of the float aggregate. Since the sinking amount of the filling float is larger than that of the float on which the load is not mounted, it is possible to prevent the float from reversing when the wave passes through the float.

It is a perspective view of the float aggregate 1. FIG. 3 is a plan view of the float aggregate 1. It is the schematic diagram which extracted the outer peripheral float 2A from FIG. 2, and displayed each float 2 typically. The outer peripheral float 2A includes a mooring float 2B, a filling float 2C, and a free float 2D, and in FIG. 3, these floats 2B, 2C, and 2D are displayed by being distinguished by different patterns. It is the figure which displayed typically the state which looked at outer peripheral float 2A and joint 3 contained in field A of Drawing 2 from the north side. It is the figure which displayed typically the state which looked at peripheral float 2A and solar panel 4 contained in field B of Drawing 2 from the east side.

Embodiments of the present invention will be described below with reference to the drawings. The various features shown in the embodiments described below can be combined with each other. Further, the invention is independently established for each characteristic item.

As shown in FIGS. 1 and 2, a float aggregate 1 according to an embodiment of the present invention is used by being floated on water such as a pond or a lake, and is configured by connecting a plurality of floats 2. In the following description, East (E), West (W), South (S), and North (N) follow the definitions shown in FIG.

The plurality of floats 2 are connected directly or via a joint 3. More specifically, the two floats 2 adjacent to each other in the north-south direction are directly connected, and the two floats 2 adjacent to each other in the east-west direction are connected via a joint 3.

Each float 2 is manufactured, for example, by blow molding in which a molten cylindrical parison is sandwiched between a plurality of split molds and expanded, and various thermoplastic resins can be used as a molding material. A polyolefin resin such as polyethylene or polypropylene can be preferably used. The float 2 has a rectangular outer shape (rectangular shape) as a whole, and has a structure having a hollow portion for containing gas (air or the like) therein. As shown in FIGS. 4 to 5, on the side surface of the float 2, a parting line PL originating from the divided surface of the divided mold during blow molding is provided. The joint 3 is similarly formed by blow molding and has a structure having a hollow portion.

A load such as a solar panel 4, a cable, a power conditioner, and a connection box is mounted on the float 2 (the load other than the solar panel 4 is not shown). Many floats 2 are equipped with a solar panel 4, and the solar panel 4 can generate electricity. The solar panel 4 is mounted in a state in which the light receiving surface is inclined so that the light receiving surface faces the south so that the power generation efficiency becomes high. The electric power generated by the solar panel 4 is transmitted through the cable. DC power from the plurality of solar panels 4 is collected in a connection box through a cable, and the DC power from the connection box is converted into AC power by a power conditioner. The connection box and the power conditioner may be installed on the ground instead of being installed on the float 2. Hereinafter, the float 2 on which the loaded object is mounted is referred to as a “mounted float”, and the float 2 not mounted is referred to as a “non-mounted float”.

The float 2 facing the aggregate outer periphery 1a surrounding the float aggregate 1 is usually used as a passage without being loaded with a load such as a solar panel 4. Hereinafter, such a float 2 will be referred to as an “outer peripheral float”, and the remaining floats 2 will be referred to as “inner floats”.

The outer peripheral float 2A is arranged along the outer periphery 1a of the assembly so as to surround the inner float. As shown in FIG. 4, one end of a mooring member 5 such as an anchor rope is fixed to part or all of the outer peripheral float 2A. The other end of the mooring member 5 is connected to an anchor submerged in the bottom G of the pond or lake, or fixed to the land around the pond or lake. This suppresses the float 2 from floating and the float aggregate 1 from flowing.
Hereinafter, the float 2 to which one end of the mooring member 5 is fixed is referred to as a "mooring float", and the float 2 to which one end of the mooring member 5 is not fixed is referred to as a "non-mooring float".

As shown in FIG. 3, the number of non-mooring floats continuously existing between two adjacent mooring floats 2B (“continuous non-mooring float number”) is preferably 10 or less, and 5 or less. It is more preferable that it is 3 or less. If this number is too large, the non-mooring floats are particularly likely to float. In this embodiment, the number of continuous non-mooring floats is three.

The ratio of the number of mooring floats 2B to the number of peripheral floats 2A is preferably 5 to 100%, more preferably 20 to 80%. If this proportion is too low, non-tethered floats will be particularly prone to lifting. If this ratio is too high, the labor of installing the mooring member 5 tends to be excessive. Specifically, this ratio is, for example, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100%, and falls within a range between any two of the numerical values exemplified here. It may be. In this embodiment, the above ratio is 25%.

The ratio of the number of mooring floats 2B to the number of peripheral floats 2A is preferably the north end or the east end or the west end≧the south end. When the solar panel 4 is inclined to the south and the north wind blows, a force in a direction of lifting the solar panel 4 is applied in the vicinity of the north end of the float assembly 1 and the float 2 easily floats. Therefore, in order to suppress the float 2 from floating, it is preferable to increase the above ratio at the north end of the float aggregate 1. Further, in the present embodiment, the two floats 2 adjacent to each other in the north-south direction are directly connected by overlapping the floats 2, while the two floats 2 adjacent to each other in the east-west direction are connected via the joint 3. Has been done. The joint 3 is an elongated member and is easily deformed when a bending force in a direction perpendicular to the longitudinal direction of the joint 3 is applied. Therefore, the float 2 located at the east end or the west end also easily floats, and it is preferable to increase the above ratio at the east end or the west end of the float aggregate 1 in order to suppress the float 2 from floating. On the other hand, when the south wind blows, a force in the direction of pressing the solar panel 4 is applied in the vicinity of the south end of the float aggregate 1, and the float 2 is prevented from rising. Therefore, at the southern end of the float aggregate 1, the above ratio may be small. Therefore, it is preferable that the above relational expression holds.

In some or all of the floats 2A of the outer peripheral float 2A, at least a part of the hollow portion is filled with the filling material. Hereinafter, such a float 2 is referred to as a “filled float”, and a float 2 not filled with a filling material is referred to as a “non-filled float”. The filled float and the non-filled float preferably have the same shape, and in that case, the only difference between them is the presence or absence of filling of the filling material.

The filling material is any substance that can be filled in the hollow portion of the filling float 2C to increase the sinking amount of the filling float 2C. Therefore, the sinking amount of the filled float 2C in a state where the float aggregate 1 is floated on the water surface WS is larger than the sinking amount of the non-loaded float, and the reversal of the filled float 2C is suppressed. Further, since the reversal of the filling float 2C is suppressed, the reversal of the other floats 2 connected to the filling float 2C is also suppressed. Further, since the filling float 2C has a lower center of gravity position than the non-filling float, the filling float 2C has high stability as a passage.

The method of filling the filling material is not particularly limited, and the filling material may be filled by forming an opening communicating with the hollow portion on the wall surface after the filling float 2C is manufactured. May be inserted. In the former case, it is not necessary to distinguish between the filled float and the unfilled float until the filling is filled, so the former is preferable. Further, in the former case, it is preferable to close the opening after the filling in order to suppress the leakage of the filled material.

The filling material is preferably a fluid such as liquid or powder, and more preferably water. When the filling is a fluid, if the filling float 2C slightly tilts, the fluid moves toward a lower direction along with the tilt, and the center of gravity of the filling float 2C becomes lower, so that the filling float 2C is inclined. Stabilize. Water is preferable because it is easy to locally procure water when filling the float assembly 1 at the installation site and there is little risk of environmental pollution in the case of leakage. That is the reason.

The filling ratio of the filling material is not limited, and the volume of the filling material in the hollow portion of the filling float 2C is preferably 1 to 70%, more preferably 30 to 50%, and specifically, for example, 1, 5, 10, 20, 30, 40, 50, 60, 70, %, and may be within a range between any two of the numerical values exemplified here. As a result, the buoyancy of the filling float 2C does not become too small, so that the filling float 2C is prevented from being submerged when an operator rides on the filling float 2C.

The filled float 2C preferably has a buoyancy of 50 kgf or more when submerged in water, and more preferably 100 kgf or more. This buoyancy is, for example, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300 kgf, and even if it is in a range between any two of the numerical values exemplified here. Good.

As shown in FIG. 5, the filling float 2C is preferably inclined so that the sinking amount becomes larger toward the outer periphery 1a of the aggregate, and the upper surface 2Ca of the filling float 2C is also preferably inclined. In this case, when the wave passes through the filling float 2C, a force in a direction of pressing the filling float 2C is applied, so that the reversal of the filling float 2C is further effectively suppressed. The inclination angle is preferably 1 to 20 degrees, and specifically, for example, 1,2,3,4,5,6,7,8,9,10,20 degrees, as exemplified here. It may be in the range between any two of the numerical values.

Further, in a state in which the float aggregate 1 is floated on the water surface WS, the filling float 2C has a portion 2Cb on the side surface facing the aggregate outer periphery 1a, which is above the water surface WS (preferably below the water surface WS and above 5 cm). 2Cb, and more preferably, below the water surface WS, the portion 2Cb above 10 cm) is an inclined surface that decreases toward the outer periphery 1a of the assembly. In this case, when the wave passes through the filling float 2C, a force is applied in the direction of pressing the filling float 2C, so that the reversal of the filling float 2C is further effectively suppressed. Further, due to the vertical movement of the water surface caused by the wave, the water surface may be lowered immediately before the wave passes, and the water surface may be lower than in normal times. Considering such a decrease in the water surface, it is preferable that the portion 2Cb above the water surface WS and above 5 cm or 10 cm is an inclined surface. The inclination angle of the inclined surface is preferably 1 to 45 degrees, and specifically, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, It is 45 degrees and may be within a range between any two of the numerical values exemplified here.

Further, as shown in FIG. 5, it is preferable that at least a part of the parting line PL of the filled float 2C is located below the water surface WS in a state where the float aggregate 1 is floated on the water surface WS. The parting line PL is usually provided in the vicinity of the vertical center of the filled float 2C, and in the non-filled float, the parting line PL is generally located above the water surface WS. In the present embodiment, at least a part of the parting line PL is located below the water surface WS, so that the center of gravity of the filling float 2C is lowered and the reversal of the filling float 2C is further effectively suppressed.

The number of unfilled floats that continuously exist between two adjacent filled floats 2C (“continuous unfilled float number”) is preferably 10 or less, more preferably 5 or less, and 3 or less. Is more preferable. If this number is too large, the unfilled float will be easily inverted. In this embodiment, the number of continuous unfilled floats is 3.

The ratio of the number of filled floats 2C to the number of peripheral floats 2A is preferably 5 to 100%, more preferably 20 to 80%. If this proportion is too low, the unfilled float is particularly liable to be inverted. If this ratio is too high, the trouble of filling the filling material tends to be excessive. Specifically, this ratio is, for example, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100%, and falls within a range between any two of the numerical values exemplified here. It may be. In this embodiment, the above ratio is 25%.

The filling float 2C may be a mooring float or a non-mooring float, but is preferably a non-mooring float. The mooring float has a fixed mooring member 5 so that it is difficult to reverse when the waves pass through. Therefore, the technical effect of using the mooring float as the filling float 2C is not great. On the other hand, since the mooring member 5 is not attached to the non-mooring float, the non-mooring float is filled with the filling float 2C to suppress the reversal, so that the technical effect is great. However, the water level of the pond or the like is not constant, and the length of the mooring member 5 is usually determined assuming the maximum water level. Therefore, when the water level is lower than the maximum water level, the mooring member 5 is in a loose state. In this state, when the float assembly 1 is hit with a wave, the entire float assembly 1 moves to mitigate the effect of the wave collision, but when the wave force is strong, the entire float assembly 1 moves. Before that, the floats 2 in the end row of the float aggregate 1 are lifted up, and even a mooring float may be inverted when the waves pass through. Therefore, by making the mooring float the filling float 2C, the reversal of the mooring float when the water level is lowered is suppressed.

The ratio of the number of filled floats 2C to the number of non-tethered floats is preferably 5 to 100%, more preferably 20 to 80%. If this ratio is too low, the non-filled float is particularly likely to float. If this ratio is too high, the trouble of filling the filling material tends to be excessive. Specifically, this ratio is, for example, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100%, and falls within a range between any two of the numerical values exemplified here. It may be. In this embodiment, the ratio is 33%.

The ratio of the number of filling floats 2C to the number of peripheral floats 2A is preferably the north end, the east end, or the west end≧south end. The reason is as described for the mooring float 2B.

Here, a float that is a non-mooring float and a non-filling float in the outer peripheral float 2A is called a "free float", and a float that is a mooring float or a filling float in the outer peripheral float 2A is called a "non-free float". ..

The ratio of the number of free floats 2D to the number of peripheral floats 2A is preferably 0 to 80%, more preferably 10 to 60%. If this ratio is too high, inversion of the free float 2D is likely to occur. If this ratio is too low, the trouble of mooring or filling may be too great. This ratio is specifically, for example, 0, 10, 20, 30, 40, 50, 60, 70, 80%, and may be within a range between any two of the numerical values exemplified here. .. In the present embodiment, the above ratio is 50%.

The average number of consecutive free floats 2D is preferably 3 or less, more preferably 2 or less, and further preferably 1.5 or less. This is because if the free float 2D continuously exists, the free float 2D is likely to be inverted. The continuous number of free floats 2D means the number of free floats 2D existing between two adjacent non-free floats. In the present embodiment, the number of consecutive free floats 2D is 1 and the average thereof is 1 in all parts.

The ratio of the number of non-free floats to the number of peripheral floats 2A is preferably the north end or the east end or the west end≧south end. The reason is as described for the mooring float 2B.
