Abstract

PROBLEM TO BE SOLVED: To respond flexibly to a force larger than expected and to allow free expansion and reduction by making a floating solid stable in the vertical direction to the wave motion due to balance between a weight of a portion above the sea level and a buoyancy in the water, by surrounding the floating solid with a net, a frame, and the like, or tying them up with line, rope, and the like. SOLUTION: Spherical solids 1 which are slightly lighter than water of place to be used are filled in the place here and there close to one another, so that gravity of the solids 1 above the sea level and a buoyancy in the water are balanced. Then, a fence 2 made of net or the like, a middle solid 4, and an inner solid 5 are provided with the sizes getting smaller in that order. In addition, size of each portion may differ. In addition, an intermediate partitioning net 6, an inner partitioning net 7, a side partitioning net 8, and a middle floating body are installed, and a number of the middle partitioning net is increased or decreased as necessary, to form a stable floating island. This enables creation of small sized, small range, inexpensive, and safe water floating structure.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications]

[0002] The present invention relates to a floating structure.

[Prior art]

Conventionally, the stability of floating structures depends on the theory of ship stability, which is 1.5 times the wavelength.

[Problems to be solved by the invention]

When the wavelength becomes 1.5 times, the wavelength becomes 150 m even if the wavelength is 100 m, which is very large. This is effective in a small area.

[Means for solving the problem]

[0005] A group of suspended solids (hereinafter abbreviated as solids) slightly lighter than the specific gravity of the water at the place of installation is surrounded by a net or the like so as not to flow out. The structure shall be stable depending on the balance.

[Action]

[0006] The buoyancy of the underwater portion thereby pushes the upper solids above the water surface. On the other hand, the solid material that comes out of the surface of the water is slightly lighter than the water, restrains the buoyancy and keeps the balance. (I think that bell stability means that the balance of a large force does not move with a small force, but a hanging bell does not move even if it is pushed from the side even if the stress in that direction is 0, the same applies to the top and bottom.) In this case, the same effect is obtained and the operation is stabilized. Also, complexly, the waves are eliminated by the same effect as the tetrapot by slipping through the solids.

【Example】

In the figure, 1 indicates a solid, and dots indicate that it is closely filled. 2 is an enclosure made of a net or the like,
3 indicates the water surface, and the arrows indicate the balance between the gravity of the solid on the water surface and the buoyancy of the solid in the water. Numeral 4 indicates a medium solid, and numeral 5 indicates an inner solid, which may be sequentially reduced. Reference numeral 6 denotes a middle partition net, 7 denotes an inner partition net, 8 denotes a horizontal partition net, and 9 denotes a middle floating body. The number of partitions is increased or decreased as necessary. The solids 1 stabilize the structure by balancing the buoyancy of the underwater portion with the gravity of the overwater portion pushed up by the buoyancy. The stability of suspended solids in water is longer and the cycle is slower and unstable and easier to move, but in the present invention, it can be stabilized by making the solid layer deep and thick. Also, each time the incoming wave passes between the solids, it is sequentially eliminated by the same effect as in the tetrapot. FIG. 2 is a partial plan view in the case of a circular shape,
FIG. 3 shows a partial sectional view thereof. If it is installed on the coast, it will be semicircular as shown in the figure. Therefore, the conventional technology is sufficient to float the middle floating body because it is the same as floating on a still water surface.However, if a solid material having buoyancy and cushioning properties such as a tennis ball is used, the elasticity is further increased. It is also possible to constitute a surface body having a property. If waste plastics are used as solid materials, resources can be conserved and two birds per stone.

【The invention's effect】

[0008] A small-scale, small-range, inexpensive and safe floating structure can be manufactured as compared with a conventional ship stability theory-based structure. It can be freely expanded or reduced in structure. Ideal for local airports, heliports, etc. Broadly, you can expand the land of Japan. Fortunately, now that territorial waters have become internationally recognized, taking advantage of the features of island nations and utilizing the method of the present invention will be much more enjoyable than having residential land on land. (Rice seems to grow at natural seawater concentration,
It will be easier if you use biotechnology. You can grow vegetables if you pile up the soil, you can keep livestock if you can, fish can eat fresh, fishing, swimming, boating, etc. are free on the spot. Electricity can be more than generated by wave power generation around the structure, and seawater can be desalinated accordingly. Desalination is also possible with solar heat. The position can be fixed / moved by attaching a sail, screw, etc.)

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications]

[0002] The present invention relates to a floating structure.

[Prior art]

Conventionally, in order for a waterborne structure to be stable, its length is required to be at least 1,5 times as long as the wavelength, based on a ship stability theory.

[Problems to be solved by the invention]

When the wavelength becomes 1.5 times, the wavelength becomes 150 m even if the wavelength is 100 m, which is very large. In order to further satisfy the effect, the structure must be a rigid non-bending rigid body like a ship. Still, if a force exceeding the design value is applied, it will be cut as seen in a tanker accident. These disadvantages are eliminated and small and affordable.

[Means for solving the problem]

[0005] A group of suspended solids (hereinafter abbreviated as solids) that are slightly lighter than the specific gravity of the water where they are installed are surrounded by a net or tied with a rope or the like so as not to flow out, and the weight of the part that emerges on the water surface and the underwater part The structure is stabilized by the balance of buoyancy. The former has a horizontal stability and the latter has a vertical stability, and the former has a rigid structure and a flexible structure.

[Action]

[0006] The buoyancy of the solids in the underwater portion thereby pushes the upper solids above the water surface. On the other hand, solid matter that comes out of the water weighs only a little lighter than water, suppressing buoyancy and keeping the balance. (I think that the stability of the bell is that the balance of a large force does not move with a small force, but the heavy bell that hangs does not move even if the horizontal component force is pushed too much.) In this case, the resistance to vertical movement is mainly the inertial resistance It depends. To give an example of 1.2,
Small floating trees move with ripples, but large vertical floating trees with a slight head above the water surface do not move with ripples. Even if a volcano blows out millions of tonnes of rocks or hits a great meteorite, the Earth's orbit will not change. In addition to such an effect, a resistance effect caused by the wave moving up and down between the solids is added to stabilize. This is naturally the case for flexible structures.

In the figure, 1 indicates a solid, and dots indicate that it is closely filled. 2 is an enclosure made of nets, etc.

The solids 1 stabilize the structure by balancing the buoyancy of the underwater portion with the gravity of the overwater portion pushed up by the buoyancy. The stability of suspended solids in water is longer and the cycle is slower and unstable and easier to move, but in the present invention, it can be stabilized by making the solid layer deep and thick. Incoming waves are sequentially eliminated by moving up and down between solids by the same effect as that of a tetrapod, but this effect also contributes to stability in the vertical direction. Therefore, a stable floating island can be obtained by enlarging FIG. 1 three-dimensionally, but a large one can be economically produced by using the structure shown in FIGS. FIG. 2 is a partial plan view in the case of a circular shape, and FIG. 3 is a partial sectional view thereof. If it is installed on the coast, it will be semicircular as shown in the figure. Therefore, the conventional technology is sufficient to float the middle floating body because it is the same as floating on a still water surface.However, if a solid material having buoyancy and cushioning properties such as a tennis ball is used, the elasticity is further increased. It is also possible to constitute a surface body having a property. If solid materials are selected from industrial waste and general waste, or if they are mixed and used, they will help the solution of the dust disposal site and conserve resources. .

In the figure, 1 is a spherical solid that is slightly lighter than the water at the place of use, and the dots indicate that it is closely packed. Reference numeral 2 denotes an enclosure made of a net or the like, reference numeral 3 denotes a water surface, and arrows indicate a balance between the gravity of the solid on the water and the buoyancy of the solid in the water.

[0002] The present invention relates to a floating structure.

[Prior art]

Conventionally, in order for a waterborne structure to be stable, its length is required to be at least 1,5 times as long as the wavelength, based on a ship stability theory.

[Problems to be solved by the invention]

When the wavelength becomes 1.5 times, the wavelength becomes 150 m even if the wavelength is 100 m, which is very large. In order to further satisfy the effect, the structure must be rigid and non-flexible, such as a ship. Then, if a force higher than the design value is applied, it will be cut as seen in a tanker accident. These shortcomings will be eliminated to allow for a small scale and small range, and allow for more force than expected.

[Means for solving the problem]

[0005] Floating solids, which are slightly lighter than the specific gravity of the water at the place where they are installed, are surrounded by nets, frames, or connected by wires, ropes, etc., and depend on the balance between the weight of the part that comes out above the water surface and the buoyancy of the underwater part. Structure. Therefore, the former rigid structure becomes a flexible structure.

[Action]

[0006] The buoyancy of suspended solids (hereinafter abbreviated as solids) in the underwater portion thereby pushes the upper solids above the water surface. On the other hand, solid matter that comes out of the water weighs only a little lighter than water, suppressing buoyancy and keeping the balance. (I think that the stability of a bell means that the balance of a large force does not move with a small force, but the heavy bell that hangs does not move even if the stationary inertia and the horizontal component force are pushed too much.) Resistance mainly depends on inertial resistance. To give an example of 1.2, a small vertical floating tree moves with ripples, but a large vertical floating tree with a slight head above the water surface does not move with ripples. Even if a volcano blows up millions of tonnes of rock above the sky or a large meteorite hits the earth, the orbit of the earth remains unchanged. In the case of a floating structure (hereinafter abbreviated as a structure), when a wave peak comes, the buoyancy of the wave first breaks its static inertia, and then lifts it, causing an upward kinetic inertia in the structure. When the wave bottom comes, the downward force by the gravity acts on the structure, but in order for the structure to actually move downward, it first wins the upward kinetic inertia and starts moving downward through the stationary state, It takes some time. In the meantime, the next wave peak comes, so the actual movement is much smaller than the height of the wave. The effect is shorter when the wave cycle is shorter, and becomes larger as the mass of the structure increases. When a wave dives between solids, the vertical movement energy of the wave is consumed by the same effect as a tetra pot, and the water level difference that raises and lowers the structure is the water level difference of the surrounding empty area Smaller and positive for the stability of the structure. In the case of the vertical floating tree with a curtain shown in Fig. 5 and the flange shown in Fig. 6, the vertical movement of the wave decreases rapidly as it goes down, and finally becomes stationary, so the curtain and the collar are sandwiched by water. Up and down movement is inhibited, and the structure is further stabilized. For a flexible structure, this is naturally the case in structure, so that even a force larger than expected can be flexibly deformed without destroying it immediately.

In the figure, 1 is a spherical solid that is slightly lighter than the water at the place of use, and the dots indicate that it is closely packed. Reference numeral 2 denotes an enclosure made of a net or the like, reference numeral 3 denotes a water surface, and arrows indicate a balance between the gravity of the solid on the water and the buoyancy of the solid in the water. Numeral 4 indicates a medium solid, and numeral 5 indicates an inner solid, which may be sequentially reduced. Either part may be used by mixing large and small. Reference numeral 6 denotes a middle partition net, 7 denotes an inner partition net, 8 denotes a horizontal partition net, and 9 denotes a middle floating body. The number of partitions is increased or decreased as necessary. If FIG. 1 is made three-dimensionally large, a stable floating island can be obtained, but the one shown in FIGS. FIG. 2 is a partial plan view in the case of a circular shape, and FIG. 3 is a partial sectional view thereof. If it is installed on the coast, it will be semicircular as shown in the figure. Up-and-down movement of the invading waves is eliminated by the same effect as the tetrapot, and the middle floating body is the same as floating on a still water surface. If a solid material having buoyancy and cushioning properties is used, a more elastic surface can be formed. If solid materials are selected from industrial waste and general waste, or if they are mixed and used, they will help the solution of the dust disposal site and conserve resources. . FIG.
Put a heavy object such as sand, earth and stone, or lead into the bottom of the hype that closed the bottom, fill it with a hollow one or fill it with a light object such as styrofoam, close the upper part so that water does not enter, and put a little head on the water surface. It is a group of things that have been adjusted to appear, and the dots indicate sets. You may mix or use together with the spherical solid of FIG. Instead of such a pipe, one having the same structure as the vertical fishing float may be used. Fig. 5 shows a part of the case where a large object of the pipe is used and the gap between solids is opened and a perforated curtain is attached below. Indicates a link. In this case, the upper structure may be designed by considering each solid as a pillar, but it is basically necessary to have a flexible structure. Fig. 6 shows a pipe with a strong flange that is thin and reinforced so that it is not easily bent below the pipe.
In the meantime, curtains and nets are stretched and used as a fence, and are suitable for fences and fish farms. Reference numeral 10 denotes a curtain or a net, and 11 denotes a flange. The number of flanges is one in the figure, but a plurality may be provided at appropriate intervals, and the effect increases as the area increases.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications]

[0002] The present invention relates to a floating structure.

[Prior art]

Conventionally, in order to stabilize a floating structure (hereinafter abbreviated as a structure), its length is required to be at least 1,5 times as long as the wavelength, based on a ship stability theory.

[Problems to be solved by the invention]

When the wavelength becomes 1.5 times, the wavelength becomes 150 m even if the wavelength is 100 m, which is very large. In order to further satisfy the effect, the structure must be rigid and non-flexible, such as a ship. Then, if a force higher than the design value is applied, it will be cut as seen in a tanker accident. In addition, it is difficult to enlarge or reduce the structure. These shortcomings will be eliminated, and the scale will be small and small, and will be able to flexibly respond to unexpected forces and expand and contract freely.

[Means for solving the problem]

[0005] Floating solids (hereinafter abbreviated as solids), which are slightly lighter than the specific gravity of the water at the place where they are installed, are surrounded by a net or frame, or connected by a line or rope, and the weight of the part that comes out on the water surface is
By balancing the buoyancy of the underwater part, the stability in the vertical direction against the wave motion is measured, or the stability is complemented by using a vertical floating wooden solid material and attaching a curtain or a flange below it.

[Action]

[0006] The buoyancy of the solids in the underwater portion thereby pushes the upper solids above the water surface. On the other hand, solids on the surface of the water weigh a little lighter than ice, which suppresses buoyancy and maintains balance.However, the structure made by the method of the invention is large, and the balance is extremely high. It is a big thing, and it is commonly known as a stable bell. (I think that the stability of a bell means that the balance of a large force does not move with a small force, but the heavy bell that hangs does not move even if the stationary inertia and the horizontal component force are pushed too much.) Resistance mainly depends on the inertial resistance of the solid. As an example of 1.2, a small vertical fishing float can move with ripples, but a large vertical fishing float with a slight head above the water surface does not move with ripples. Even if a volcano blows up millions of tonnes of rock above the sky or a large meteorite hits the earth, the orbit of the earth remains unchanged. In the case of this structure, when the wave peaks, the buoyancy of the waves first destroys its static inertia, and then lifts it, creating an upward kinetic inertia in the structure. When the wave bottom comes, the downward force by the gravity acts on the structure.However, in order for the structure to actually move downward, it first overcomes the upward kinetic inertia and starts moving downward through the static state. , It takes some time. In the meantime, the next wave peak comes, so the actual movement is much smaller than the height of the wave. The effect is shorter when the wave cycle is shorter, and becomes larger as the mass of the structure increases. Also, when a wave dives between solids, the energy of the vertical movement of the wave is consumed by the same effect as a tetra pot, and the water level difference that raises and lowers the structure is the water level of the wave in the surrounding empty area Smaller than the difference, which is a plus for the stability of the structure. In the case of a vertical solid floating type solid body (hereinafter, abbreviated as a vertical floating type) with a curtain of FIG. 5 and a flanged pipe of FIG. 6, which will be described later, the vertical movement of the wave decreases rapidly as it goes down, Eventually, the curtain or the brim is hindered from moving up or down due to little movement or still water, and has an effect of further stabilizing the structure. For a flexible structure, this is naturally the case in structure, so that even a force larger than expected can be flexibly deformed without destroying it immediately.

【Example】

In the figure, 1 is a spherical solid that is slightly lighter than the water at the place of use, and the dots indicate that it is closely packed. Reference numeral 2 denotes an enclosure made of a net or the like, reference numeral 3 denotes a water surface, and arrows indicate a balance between the gravity of the solid on the water and the buoyancy of the solid in the water. Numeral 4 indicates a medium solid, and numeral 5 indicates an inner solid, which may be sequentially reduced. Either part may be used by mixing large and small. Reference numeral 6 denotes a middle partition net, 7 denotes an inner partition net, 8 denotes a horizontal partition net, and 9 denotes a middle floating body. The number of partitions is increased or decreased as necessary. If FIG. 1 is made three-dimensionally large, a stable floating island can be obtained, but the one shown in FIGS. FIG. 2 is a partial plan view in the case of a circular shape, and FIG. 3 is a partial sectional view thereof. If it is installed on the coast, it will be semicircular as shown in the figure. Up-and-down movement of the invading waves is eliminated by the same effect as the tetrapot, and the middle floating body is the same as floating on a still water surface. If a solid material having buoyancy and cushioning properties is used, a more elastic surface can be formed. If solid materials are selected from industrial wastes and general wastes, and processed or mixed as necessary, they can be used as a solution for dust disposal sites and contribute to resource conservation. Become three birds. Fig. 4 shows sand, earth and stone,
Put a heavy object such as lead, make a cavity above or fill it with a light object such as styrofoam, block the upper part so that water does not enter, and adjust the vertical floating wood type that adjusts so that a little head comes out above the water surface The dots indicate sets. You may mix or use together with the spherical solid of FIG. Instead of the vertical floating type, a vertical floating type for fishing may be used. Fig. 5 shows a part of the case where a large object of the pipe is used and the gap between solids is opened and a perforated curtain is attached below. Indicates a link. In this case, the upper structure may be designed by considering each solid as a pillar, but it is basically necessary to have a flexible structure. Fig. 6 shows a case in which a thin, strong flange reinforced so as not to be easily bent is attached in parallel below the vertical floating block type, and curtains, nets, etc. are stretched between them and used as an enclosure. It is suitable for enclosures of fish farms and fish farms. Reference numeral 10 denotes a curtain or net, and 11 denotes a brim.
The number of flanges is one in the figure, but a plurality may be provided at appropriate intervals, and the effect increases as the area increases.

【The invention's effect】

(B) Compared with conventional ship stability theory-based structures, it is possible to manufacture small-scale, small-range, inexpensive, and safe floating structures. C Suitable for local airports and heliports. D) It can broaden Japan's land. Fortunately, the territorial waters have become widely recognized internationally, and utilizing the features of the island nation and utilizing the method of the present invention makes it much more enjoyable than having a residential land on land. Paddy rice is likely to grow at natural seawater concentrations, making it easier if biotechnology is used. You can grow vegetables if you pile up the soil, you can keep livestock if you can, fish can eat fresh, fishing, swimming, boating, etc. are free on the spot.
Electricity can be generated more than necessary by wave power generation around the structure,
The seawater can be desalinated accordingly. Desalination is also possible with solar heat. The position can be fixed / moved by attaching a sail, electric screw, etc., and can be moved on the tide. If such floating islands of various sizes are formed on the ocean, the history of humanity may have changed. (E) In the case of FIG. 4, the oil fence can have a higher water wall than the current bag type, and is stable and effective even in stormy weather. It has the effect that it can be installed in the open sea as a culture pond.
