The present invention comprises a float unit body capable of supporting a heavy object in a predetermined range by appropriate buoyancy on various water surfaces such as the sea, lakes, and rivers, and a structure in which a plurality of these are connected in combination, such as solar power generation.

The use of land for the effective use of natural energy such as solar power generation is largely limited by the effective use of space and cost problems, and most of the proposals are experimental. In view of this, new technologies have been proposed for effective use of various water surfaces such as the sea, lakes, and rivers that have sufficient space and little use cost.

Specifically, some proposals have already been made to create an artificial floating island and float it on the surface of the water, and use it appropriately according to the purpose.

Also, recently, demonstration experiments have been carried out by floating a huge artificial floating island called Mega Float on the sea. Further, as a multi-purpose simple float structure, those shown in the following documents are disclosed.

The present invention is also characterized in that, in the above-described means for floating the water structure, a photovoltaic power generation panel or a solar thermal power generation device is arranged on the surface of the water surface of the floating float structure to provide power generation equipment using sunlight or solar heat. .

According to the present invention, in the water float structure of the above means, at least a part of the water float unit constituting the water float structure has a water purification function using activated coal material and microorganisms. Features.

The present invention is also characterized in that, in the above-described water float structure, a wind power generator or a wave power generator is disposed on the water float structure to provide a power generation facility using natural energy.

The present invention is also characterized in that in the water float structure of the above means, various plants can be grown on the water float structure.

(A) A connectable float unit that floats on the water, and uses a plurality of automobile waste tires filled with a buoyancy material as a main buoyancy body, and an effective buoyancy per 1 m ² is 30 kg or more, preferably 40 kg or more. By doing so, it is possible to use the surface float unit of the present invention for various purposes as long as the effective buoyancy can be used.

In other words, the effective buoyancy in this range is insufficient to safely and reliably float an object with a weight exceeding 100 kg per 1 m ² . However, for example, currently popularized panels for photovoltaic power generation have been reduced in weight, so the panel weight per 1 m ^{2 of the} floating unit can be 30 kg or less.

In other words, when it is intended to support such a lightweight article, there is no need for a float material that supports a considerable weight, and it is sufficient to have an effective buoyancy equivalent to the floating unit of the present invention. That's it. Therefore, there is no problem even if the effective buoyancy required in the present invention is less than 100 kg per 1 m ² , generally 80 kg or less.

In addition, in the case of aiming to support a relatively light article whose weight per 1 m ² does not exceed 100 kg, it is relatively compared with a float material that supports a considerable heavy object. It is understood that even if it has less strength and durability, it is sufficiently useful.

(B) Filling the waste tire with a specific gravity of 0.5 or less, preferably 0.3 or less so as not to leak so as to fill 90% or more, preferably 95% or more of the volume in the waste tire. By using the buoyancy body, the effective buoyancy of the float unit of the present invention can be realized. Although the waste tire itself sinks in water, the inventor has confirmed that the above-described effective buoyancy can be achieved by appropriately packing such a buoyancy material inside. It has also been experimentally confirmed that a rubber waste tire has sufficient strength and durability as a water float unit for use in the present invention.

If a float material having such strength and durability is to be industrially produced by conventional general technology, it will inevitably cost considerably, and new resources will have to be consumed. However, when the waste tires are reused, the cost can be significantly reduced and the consumption of new resources is not required.

(C) By using a foam material such as polystyrene foam that is divided into a plurality of shapes according to the shape of the waste tire as the buoyancy material, the specific gravity of the above buoyancy material is 0.5 or less, preferably 0.3. It is possible to satisfy the following conditions. There are various other buoyancy materials as long as these conditions are satisfied. However, it is understood that, in view of cost and stable supply, expanded polystyrene is optimal at present. In addition, the expanded polystyrene does not need to be new, and can be reused after being used for other purposes. In this case, it is understood that the cost is further reduced.

(D) Since the surface of the buoyancy material is surface-treated with a coating or a laminate so that elution of chemical substances into water does not occur, buoyancy materials such as styrene foam that will be left in water for a long time. It is possible to prevent chemical substances such as environmental hormones that are harmful to the environment from being dissolved. Such consideration is useful because the float unit of the present invention should reduce the load on the surrounding environment as much as possible.

Any coating and laminating material that can achieve this purpose may be used, but it is preferable to use natural rubber or silicon rubber. In addition, regarding waste tires, it has been confirmed that there is virtually no elution of chemical substances over a considerable period of time, but the same coating or laminating may be performed as necessary.

Also increase the overall buoyancy body buoyancy by incorporating an auxiliary buoyant material integral with the hollow portion of the (e) the tire center, 1 m ² per effective buoyancy of 45kg or more, preferably by a least 60 kg, more weight It is possible to achieve safe and stable buoyancy support even for articles with a certain size and to use them according to the purpose. It is understood that the waste tire itself has a donut shape, and the hollow portion in the middle is not such that buoyancy is produced when the water float unit is formed.

The effective buoyancy of the surface float unit itself can be improved by integrating the auxiliary buoyancy material in this part as well. There is no problem in strength and durability, and there is still a margin in effective buoyancy, so it can be used for more versatile applications. Further, the auxiliary buoyancy material may be a material in which various buoyancy materials are packed in a hollow cylindrical body such as a drum can having a size substantially the same as the hollow portion of the used tire.

(F) After sealing the number of empty cans and PET bottles sufficient to ensure a volume equivalent to 80% or more, preferably 90% or more of the tire internal volume, while maintaining the shape of the container, and arranging them inside the tire The buoyancy body (water float unit) with the buoyancy according to the application while taking advantage of the strength and durability of the tire itself by packing and sealing the opening and setting the water buoyancy per tire to 25 kg or more Will be able to make. Of course, tires, empty cans, and PET bottles may be recycled from used ones. Reduces material costs and enables environmentally friendly manufacturing through recycling.

(G) By filling with foamed polystyrene in an empty can or a plastic bottle and sealing it, it becomes possible to obtain a buoyancy body (water float unit) that does not lose buoyancy even if a hole is opened.

(H) Since the foamed polystyrene filled in empty cans and PET bottles is the waste foamed polystyrene crushed, it is possible to contribute to the recycling of waste foamed polystyrene.

(I) Sealing of empty cans and PET bottles is performed with an adhesive that does not harm the welding or water quality environment, so even if the floating unit of the present invention is installed in a natural water area, environmental pollution Risk can be eliminated. About the specific welding method and adhesive material, what is necessary is just to employ | adopt the well-known thing which the effect established.

(J) A buoyancy material is also packed in the hollow portion in the center of the tire, and is sandwiched between upper and lower plates and fixed by fasteners so that the water buoyancy per tire is 35 kg or more, preferably 40 kg or more, thereby further increasing the buoyancy. It becomes possible to realize a buoyancy body (water float unit body) that has it.

(K) Since the buoyancy material packed in the hollow portion in the center of the tire uses empty cans and PET bottles, further recycling of empty cans and PET bottles can be promoted.

(L) By making the tire used as a buoyant body connectable in the vertical and forward / backward / left / right directions, the water buoyancy per unit area can be increased or applied to the desired application area. This makes it possible to create a free floating unit regardless of the installation location, from the water area to the large lake or the sea.

(M) Since the upper / lower / front / rear / right / right connection structure uses rods and ropes, it is possible to make a floating unit of any size with a simple structure.

(N) A plurality of tires as buoyancy bodies can be placed horizontally and stacked, or if necessary, the tires can be rolled and placed vertically so that they can move on land, thereby adjusting the overall buoyancy of the float unit. Thus, the buoyancy per unit area can be increased or decreased according to the purpose. In other words, the inventor has demonstrated that a buoyancy of about 30 kg to 40 kg can be obtained per unit when a buoyant material is packed in a tire of a size used in a normal passenger car to form the water float unit of the present invention. However, for example, how many tires are arranged per square meter can be freely selected depending on how a plurality of tires are arranged.

Moreover, if the tires are vertically arranged as shown in the figure and a single mandrel is passed through each center, the whole can be rolled and moved on land or the like, and the float unit of the present invention By appropriately applying to the body, it is possible to roll and move the tires provided on the water float unit on land, and to float and move on the water.

(O) The floating float units themselves can be stacked and connected in multiple stages to increase the overall buoyancy, thereby providing an appropriate connection structure in addition to devising the arrangement relationship of multiple tires themselves as buoyancy bodies. In addition, it is possible to realize a target buoyancy by stacking and connecting the water float units themselves of the present invention in multiple stages. By appropriately adopting a well-known connection method with sufficient strength, the water float unit of the present invention can be reliably connected not only to the front / rear / left / right plane direction but also to the upper / lower vertical direction. .

(P) As long as the buoyancy required for the water float unit can be secured, by providing a part of the water float unit that is not supported by the buoyancy body, the part is daylighted in water, It can be used for purposes such as an opening for observing underwater conditions and an opening for water intake. It is sufficient that the effective buoyancy required for the floating body of the present invention is realized as a whole, and there is no problem even if there is a part that is not supported by the buoyancy body (tire). As such a configuration, as shown later, 1) a portion without the buoyancy body (tire) itself is provided, and 2) an auxiliary buoyancy material that does not incorporate an auxiliary buoyancy material in the center of the tire as a buoyancy body is used. For example, a method of connecting adjacent unit bodies in the form of bridging them in the horizontal direction of the front, back, left and right of the float units in the present invention is conceivable. In addition to the above, the effective use of this part can be considered as appropriate.

(Q) As the connection of the float unit on the water, it is possible to connect not only in the horizontal direction but also in the vertical direction in which the water float units are stacked in multiple stages. Can be realized. By calculating the effective buoyancy of each part, it is possible to realize a floating structure with an appropriate slope composition.

(R) When the shape of the floating unit is adapted to the shape of the loading platform such as a transport vehicle for transporting it, when it is necessary to transport it on land, It becomes possible to carry out easily and quickly. As the shape of the loading platform, it is desirable to adopt the greatest common divisor so as to be compatible with a wide variety of transportation vehicles.

(S) By using the floating unit on the surface as the installation equipment for the photovoltaic power generation panel, it is possible to construct an offshore (offshore) photovoltaic power generation facility easily and at low cost.

(T) By connecting a plurality of water float units of the present invention using waste tires to form a water structure (water float structure) having a desired area, various sizes according to the intended use can be obtained. The water structure can be easily completed by simple connection work at the construction site. The size of the float unit of the present invention is limited to a certain size, so how many and how to arrange it should be designed as necessary, and construction according to that should be done on site. It becomes.

(U) Within the range where the buoyancy required for the entire floating structure is secured, the effective buoyancy required for the entire structure is achieved by connecting the floating units in a bridging manner without bringing them into close contact with each other. While maintaining the above, it is possible to freely design a configuration in which a water channel or the like is provided at a desired location. As described above, while ensuring the effective buoyancy of the entire structure required in the present invention, it is sufficiently possible to include a portion that is not supported by a buoyancy body that partially reuses a tire or the like. Therefore, it is possible to configure a waterway that becomes a passage for boats and the like used for transportation and management.

(V) Floats by other technologies having strength, durability, large buoyancy, etc. that are difficult to realize with the technology of the present invention by combining with float units other than buoyancy bodies using waste tires. It becomes possible to make a floating structure with a composite structure in combination with the structure. In such a portion having strength, durability, and greater buoyancy, machinery or the like having a considerable weight that is difficult to support while securing safety can be disposed in the present invention.

Also, the structure to be combined is not limited to the float type, but may be a fixed structure using the bottom of the water or the land. Free design according to the purpose and the situation of the site is possible.

(W) By arranging solar power generation panels and solar thermal power generation equipment on the surface of the surface of the floating structure, and using solar power and solar power generation facilities, it is possible to use the sea where there is no object blocking the sunlight. And large-scale power generation facilities can be easily created.

Power generation facilities such as solar power generation panels and solar thermal power generation devices are relatively lightweight and must be kept on the water sufficiently safely with an effective buoyancy of about 30 kg to 40 kg per square meter realized with the floating structure of the present invention. Is possible. Those with sufficiently excellent power generation efficiency have been realized, and it is expected to implement solar power generation on a large scale in order to realize a low-carbon society. In order to install the photovoltaic power generation panel over a wide area, it is appropriate to use the sea or the like. However, there is no low-cost large-scale floating structure other than the present invention. It can be understood that the present invention is very effective as a technique for supporting buoyancy of a relatively lightweight article that can be effectively used on the sea and other water surfaces in a safe and large area.

Of course, when floating on the sea, sufficient care is taken to avoid the adverse effects of salty seawater, but it is sufficient to simply apply existing technology. A practical solution to a method for protecting a structure from the influence of waves can be achieved by appropriately combining known techniques.

In addition, it has been confirmed from the demonstration experiment such as mega float that the sea levitation equipment has almost no load on the surrounding natural environment, and it can be moved and can be easily restored to its original state before installation. Has advantages.

Cost is a problem for the spread, but in the case of the present invention that maximizes the reuse and recycling of waste tires etc., the unit cost per square meter can be reduced to several thousand yen or less, Not only is it cheaper than landfill, but it can also be implemented at a much lower cost than a heavy float capable of supporting heavy loads such as a mega float that has several decades of durability. Yes.

(X) At least a part of the water float unit constituting the water float structure has a water purification function using activated coal material and microorganisms, so that the water area where the water float structure of the present invention is installed can live. Even when it is contaminated by eutrophication with waste water or the like, it is possible to achieve the unique object of the present invention in combination while purifying it appropriately.

It is considered that the surface of the sea and the surface of the lake where the present invention is implemented may be subject to water pollution due to various human activities, while at the same time achieving various purposes while appropriately purifying this, and then reducing the environmental burden. It is possible to remove the floating structure of the present invention after restoring the original natural state without giving it. Further, not only activated coal but also various materials can be applied as long as the material has a fine structure sufficient to propagate microorganisms.

(Y) Since the floating structure is a power generation facility using various natural energies such as wind power generators, ocean currents, wave power generators, etc., various natural energies that can be used at the place where the present invention is implemented are not wasted. It becomes possible to generate electricity while using it effectively. Of course, possible combinations are made within the range of the capability of the floating structure of the present invention, but by combining with an appropriate management and adjustment system, the most efficient power generation can be performed from time to time depending on the situation. It is possible to design to adjust the means to be main.

(Z) By allowing various plants to be grown on the floating structure on the water, it is possible to effectively grow plants used for high-value-added applications such as bioenergy generation, food use, and ornamental use. It becomes possible to improve the property. Of course, since plants absorb carbon dioxide, it is not only a power generation facility that does not emit carbon dioxide, but it is also possible to effectively absorb carbon dioxide and make available resources at the same time. In general, it is normal that sunlight is abundant on a vast water surface, and it can be easily understood that it can be effectively used for plant growth by preparing an appropriate growth environment.

Some examples of specific embodiments of the present invention as described above will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic view when a waste tire 1 (for example, a waste tire for automobiles) used in the present invention is used as a buoyancy body 1a. Various materials can be used as the buoyancy material 2 packed in the waste tire 1 as long as it has a specific gravity within a predetermined range. Typically, various resins such as foamed polystyrene and foamed materials such as rubber are preferable. The foamed polystyrene may be recycled waste foamed polystyrene, but it is desirable to reshape the donut shape into some divided parts as shown in the figure and then pack it into the waste tire 1.

The foamed material 2 that is made by dividing the donut shape using this polystyrene (approximately 6 to 8 parts), if it is immersed in water, may gradually elute harmful chemical substances. In order to prevent this, it is necessary to laminate the surface with a safe material such as silicon rubber.

It has been confirmed that the standard buoyancy of the buoyancy body 1a constructed in this way is about 25 kg per waste tire 1, and the float unit of the present invention is formed by appropriately arranging the buoyancy bodies 1a. 3 (described later) can be understood that an effective buoyancy of 30 kg to 40 kg or more per 1 m ² can be achieved.

FIG. 2 shows some examples in which the effective buoyancy of the buoyancy body 1a is further improved by incorporating the auxiliary buoyancy material 5 integrally into the hollow portion 4 of the buoyancy body 1a. The auxiliary buoyancy material 5 has a cylindrical shape, and a central shaft member 6 can be provided in the middle. This center shaft member 6 can be used for the attachment structure when the floating unit 3 is constructed or for the connection between the buoyancy bodies 1a.

Further, when a plurality of waste tires 1 are stacked to form an integral buoyancy body 1a, the height of the cylindrical auxiliary buoyancy material 5 can be integrated according to the thickness of the number of tires. It is.

The inventor has confirmed that the effective buoyancy of the buoyancy body 1a is improved by about 30% to 50% by incorporating the auxiliary buoyancy material 5 integrally. That is, by this, the effective buoyancy of the surface float unit 3 of the present invention can be improved to about 60 kg in terms of 1 m ² .

FIG. 3 is an explanatory diagram showing the structure of the buoyancy body 1a using the waste tire 1 of the present invention as described above in a perspective view from the lateral direction.

That is, a case where two to three or more waste tires 1 are stacked and the auxiliary buoyancy material 5 is integrally incorporated in the hollow portion 4 to form the buoyancy body 1a is shown. It is what. Naturally, the effective buoyancy can be adjusted depending on how many waste tires 1 are stacked.

The water float unit body 3 of the present invention is configured by combining the buoyant bodies 1a formed in this way into a predetermined shape of a predetermined size. FIG. 4 shows a representative example of the water float unit 3 in a plan perspective view.

FIG. 4A shows a case where the buoyant bodies 1a of the waste tires 1 are arranged side by side (that is, the waste tires 1 are placed side by side so that the central axis thereof is in a substantially vertical direction). 1 shows a case where a rectangular floating unit 3 is formed. In FIG. 4B, the waste tires 1 are arranged vertically in the same size and shape on the surface of the float unit 3 (that is, the waste tires 1 are placed vertically with the center axis of the waste tires 1 being substantially horizontal). In this case, 28 waste tires 1 are required.

As described above, the number of tires required to form the same shape and size of the floating float unit 3 can be varied depending on whether the waste tires 1 are arranged vertically or horizontally. It is possible to use it.

FIG. 5 shows a case in which a portion (part where the waste tire 1 is partially missing) 7 that is not partially supported by the waste tire 1 is formed in the above-described water float unit 3 of the present invention. Some examples are shown. That is, as long as the buoyancy required per square meter is achieved on the average as the entire floating float unit 3, the portion 6 that is not supported may partially exist.

This part can be used for lighting in the water, entrances and exits for inspection / maintenance, and other purposes by providing a part like a window in the floating unit 3. Further, in the case of the configuration in which the waste tires 1 are arranged side by side, the same result can be obtained by making a part in which the auxiliary buoyancy material 5 is not partially incorporated.

FIG. 6 is an explanatory view showing some examples of the surface float unit 3 of the present invention in a side perspective view. FIG. 6A shows a case where the buoyant bodies 1a of the waste tires 1 are arranged vertically (that is, the waste tires 1 are arranged vertically). In this case, each waste tire 1 can be smoothly rotated by inserting the central shaft member 6, and a flat land surface or the like can be moved using the rolling of the waste tire 1. Of course, it is easy to tow and move on the surface of the water, but in this case, movement on land can also be easily performed.

FIG. 6B shows a case where the buoyant bodies 1a of the waste tires 1 are vertically stacked and arranged horizontally (that is, the waste tires 1 are horizontally placed and three stacked vertically). Show. Also in this case, it is shown that a set of three buoyancy bodies 1a is collected by the central shaft member 6 and these are arranged side by side to form the water float unit body 3 according to the present invention.

The water float unit 3 of the present invention made in this way can keep floating on the lake and sea water for a long time while ensuring an appropriate effective buoyancy, and since the upper surface is formed flat, It is understood that it can be used for various purposes.

As one of such utilization methods, it is conceivable to arrange the photovoltaic power generation panels 8 to constitute the constituent parts of the photovoltaic power generation equipment, and FIG. 7 shows an example in that case.

The weight of the present solar power generation panel 8 is not more than 30 kg per square meter even if it has a considerably high performance, and can be stably placed and held on the water float unit 3 of the present invention. Is possible. The illustrated one shows a state where nine photovoltaic power generation panels 8 are arranged.

When the floating unit 3 of the present invention is used as a component of such a photovoltaic power generation facility, a large number of floating

units

3, 3 are connected to the sea surface or the like in order to realize more efficient use. Need to be placed side by side. FIG. 8 shows an example of the case where such an interconnection is used to form the floating structure 9 on the water.

In this case, a total of 24 water float units 3 are arranged side by side to form a water float structure 9, but of course this is not limited to this, and the shape by interconnection is designed in various ways according to the construction site. Is possible.

The size of the float unit 3 according to the present invention is not particularly determined, and may be determined and determined appropriately from the situation of the construction site and the efficiency of the assembly work. Depending on the purpose of use, depending on the purpose, it is possible to make a huge floating structure 9 by interconnecting several hundred or more floating units 3.

The water float structure 9 does not need to be integrated as a whole. As shown in FIG. 9, the water float unit 10 partially lacks the water float unit 3 or the water float in a slightly separated place. A structure in which the structures 9 are connected to each other by a floating bridge 11 can also be adopted. That is, since the water float unit 3 having an appropriate size can be freely connected and designed, the water float structure 9 can be formed in various shapes according to the purpose of use.

Furthermore, the interconnection of the floating

unit bodies

3 and 3 of the present invention may be stacked one above the other. As shown in FIG. 10, it floats with respect to the water surface 12 in a state of being stacked in two steps or partially in three steps, and the plate 13 is passed over the step portion formed on the water surface to form the inclined portion 13a. Is possible. It is possible to increase the exposed portion of the water by multi-stage stacking, or to form a three-dimensional step or slope on the water.

FIG. 11 shows an example in which a partial passage portion 14 is provided in the floating float structure 9 of the present invention. That is, when the floating structure 9 is appropriately used for various applications such as photovoltaic power generation, human work, periodic maintenance, and the like are considered, and the weight exceeding the effective buoyancy assumed in the present invention is temporarily used. There are situations that must be supported. In this way, when it is necessary to support a weight that partially exceeds the assumed buoyancy, by attaching a portion having a larger buoyancy that supports it as the passage portion 14, various operations can be performed safely. This is what we consider. This part may be a fixed structure from the bottom of the water according to the situation of the construction site.

In addition, the present invention can also have a water purification function in the construction water area. That is, as shown in FIG. 12, a water quality purification member 15 in which microorganisms such as Bacillus bacteria having a water quality purification ability are attached to a light microporous structure granular material or the like is attached to the bottom of the floating unit 3 in water. Thus, it is possible to perform water purification in parallel while performing solar power generation with the solar power generation panel 8 on the water surface.

Regarding the combined use of such a floating float structure 9, it can be combined with wind power generation, ocean currents, wave power generation facilities, or cultivation of useful plants on the water surface, and within the effective buoyancy range. Even so, various purposes can be achieved.

FIG. 13 is a diagram (side view) showing an example in which the wave power generation device 20, the wind power generation device 21, and the solar power generation panel 8 are arranged on the floating float structure 9. In this example, a buoyant body 1 a made up of waste tires 1 is placed horizontally and stacked up and down to form a water float unit 3, and a plurality of the water float units 3 are arranged to form a water float structure 9. Yes.

And the wave power generation device 20 is disposed so that a part of the wave power generation device 20 is submerged under the water surface 12 between the water float units 3. In the wave power generator 20, the internal water surface 20b in the pipe-shaped conduit 20a moves up and down with the movement of the external wave, and the air in the upper air chamber 20c generated by the vertical movement of the internal water surface 20b. The turbine blade 20d is rotated by this flow to generate electric power.

In this way, by arranging the plurality of wave power generation devices 20 so as to be sandwiched between the plurality of floating unit bodies 3, the plurality of wave power generation devices 20 are efficiently arranged in a partially submerged state. can do. In particular, in this example, a plurality of buoyancy bodies 1a are stacked up and down to constitute the water float unit 3, so that it is possible to generate the necessary buoyancy without increasing the space occupied in the horizontal direction. .

Further, by arranging the plurality of wave power generation devices 20 so as to be sandwiched between the plurality of floating unit bodies 3, the exposed portion of the water above the floating structure 9 becomes an empty space. It becomes possible to arrange the equipment. Therefore, if the wind power generator 21 and the solar power generation panel 8 are arranged on the upper part of the floating structure 9 as in this example, the floating structure 9 is utilized as a combined power generation facility using natural energy. It becomes possible to do. The wave power generation device 20 is not limited to the structure shown in FIG. 13 and may have other structures. Moreover, you may make it arrange | position the electric power generation apparatus using other natural energy, such as a solar thermal power generation apparatus, an ocean current power generation apparatus, etc., for example.

FIGS. 14A and 14B are diagrams (plan views) showing an example of horizontal arrangement in the case where the wave power generation device 20 is arranged on the floating float structure 9. When the wave power generation device 20 is disposed on the water float structure 9, for example, as shown in FIG. 14 (a), the wave power generation device 20 is disposed between a plurality of water float unit bodies 3 arranged in a lattice pattern. Alternatively, as shown in FIG. 14B, the floating unit 3 and the wave power generator 20 may be arranged in a staggered manner. That is, the horizontal arrangement of the water float unit 3 and the wave power generator 20 is appropriately determined according to the size of the water float unit 3 and the wave power generator 20, the required buoyancy, the use conditions, and the like. Other arrangement methods may be employed.

It should be noted that it is practically convenient to design the floating float body 3 of the present invention so as to be suitable for the size of a carrier such as a transportation vehicle in consideration of convenience such as land transportation. That is, the water float unit 3 is set to a size that can be loaded on a loading platform of a general transportation vehicle such as a truck or a freight train, or a size corresponding to a standard such as a freight container. Since there is no need to prepare a vehicle or the like, land transportation can be facilitated.

Furthermore, as long as the water float structure 9 (water float unit 3) is used for the applications described above, no additional energy consumption is required, and various natural energies are easy to use and useful for humans. It can be said that it is supplied after being converted into a form, and it can be used meaningfully for the future global environment.

Next, some examples of other embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 15 is a side view of an example of the basic configuration of the buoyant body 31 of the present embodiment. That is, as shown in FIG. 15 (a), a tire (waste tire) 32, an additional buoyancy material 34 fitted into the hollow portion 33 at the center of the tire, and a rubber or the like that at least substantially seals the additional buoyancy material 34 from above and below. A disk-shaped sealing material 35 made of a flexible material, a disk-shaped fixing material 36 made of a rust- and salt-resistant metal that is also sandwiched and fixed from above and below, a metal rod or metal for forming an sandwich-fixed structure A shaft rod member 37 made of a pipe or the like, and a fixing material 38 for forming a fixed relationship by screwing or the like through the shaft rod member 37 are basically configured, and an empty can or A container 39 such as a plastic bottle is used.

A basic unit body of the buoyant body 31 of the present embodiment as shown in FIG. 15B is formed by combining these components. Among such constituent elements, at least the tire 32 and the container 39 such as an empty can or a plastic bottle may be recycled after being used normally (that is, a waste tire or a waste container).

FIG. 16 shows an example of a case where containers 39 such as empty cans and plastic bottles used as substantial buoyancy materials for the tire 32 and the additional buoyancy material 34 are aligned and packed so as to eliminate useless gaps. FIG. 16A shows a case in which containers 39 such as empty cans enclosed in the additional buoyancy material 34 are vertically arranged, and FIG. 16B shows that the containers 39 such as empty cans enclosed in the tire 32 are similarly arranged. This shows the case where they are aligned vertically. Of course, horizontal alignment or a mixture of the two may be used, and an alignment method necessary for packing without gaps may be selected as appropriate from the viewpoint of securing buoyancy as much as possible.

FIG. 16C is a perspective view showing a state in which the crushed foamed polystyrene 40 is sealed in the container 39. By filling a sufficient amount of crushed foamed polystyrene 40, the container 39 is not depressed by an external pressure or the like, and a constant buoyancy can be maintained.

The sealing method of the container 39 may be a known method such as welding or adhesive, but a method that impairs the water quality environment of the installation water area beyond the standard is not adopted. Further, the additional buoyancy material 34 can be used alone as an independent float material (buoyancy body).

FIG. 17 shows a few examples of a technique for connecting a plurality of buoyancy bodies 31 to each other to form a floating unit 43 on the water. FIG. 17A shows an example in which the shaft rod member 37 protruded up and down is used for connection by a linear rod member 41, and FIG. 17B shows the pipe-like shaft rod member 37. In this case, a case where a loop is formed by a rope 42 or the like through the pipe hole is shown.

Of course, there is no problem in adopting other known connection methods. The use of the bar 41 is stronger than the connection by the rope 42, but a flexible connection method may be suitable, and it may be selected as the appropriate material at the right place.

FIG. 18 shows an example in which the floating float body 43 is formed by using the bar 41 so as to have a planar extension in the front-rear and left-right directions. In this case, the bar 41 is also combined with the front, rear, left, and right characters in order to have a firm connection structure. In this way, the bowl-shaped water float unit 43 is completed. By freely changing the number and combination shape of the buoyancy bodies 31, it is possible to freely design the overall size and shape in conformity with the water topography at the installation location.

FIG. 19 shows an example of a case in which a connection method using a line-like material such as a rope 42 is employed when forming the floating unit 43 with the front / rear / left / right planar expansion similar to FIG. Yes. In this case, it is desirable that the connection be made firmer by adding not only a cross-shaped direction but also an oblique direction depending on the situation.

FIG. 20 shows an example in the case where the above-described water float unit body 43 by connecting a plurality of buoyancy bodies 31 of the present embodiment as described above is used for installing the photovoltaic power generation panel 44. In this way, the use of the water float unit 43 realizes the possibility of a solar power generation facility on the water (on the sea), which has been largely omitted in the past.

Using a buoyancy material 2 made of waste tire 1 and Styrofoam, a float unit 3 with a height of 3m, a width of 2m, and a height of 0.5m was created and floated on the surface of the water. It was confirmed that even if a solar cell panel was placed on the buoyancy structure with the solar cell power generation, no further trouble occurred. It was confirmed that the stability of the entire structure is increased and the influence of wind and waves is reduced by firmly connecting the plurality of floating units 3 by a known method.

In addition, regarding the strength and durability, the target object to be supported by buoyancy was a lightweight solar cell panel of 20 kg or less. There wasn't.

It was confirmed that the float unit 3 of the present invention is sufficiently effective as long as it supports an article within the range of effective buoyancy assumed in the present invention.

A water solar power generation facility was actually constructed experimentally using the water float unit 43 of the present invention shown in FIG. It was confirmed that solar power generation would be realized if it was on the surface of water with sufficient sunshine conditions.

On midsummer days, the temperature is kept lower on the surface of the water than on land, so good results can be expected for power generation efficiency decline due to high temperatures. If it is on freshwater bodies, there is no need for water resistance treatment on the panel itself. In the case of the sea surface, salt-resistant treatment is necessary, but this is also possible with existing technology, and it was judged that the cost could be sufficiently reduced by mass production.

In the case of eutrophication-polluted water areas and the like, sunlight in the water is suppressed, and the effect of preventing abnormal occurrences of phytoplankton such as sea lions was also observed.

According to the present invention as described above, a float material having effective buoyancy capable of appropriately and safely levitating and supporting a relatively light article having a weight of only about several tens of kg per square meter, and a float structure combining them. It is possible to obtain a large amount of goods at low cost, and it is possible to efficiently install facilities such as the installation of solar power generation panels on the surface of the water such as the ocean, At the same time, it can be applied to other purposes as appropriate, and it can be expected to be an invention that plays a major role in modern society where the purification of the global environment is regarded as a problem. It can be understood that this is an excellent invention.
