Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating device for storing and drawing water.

[0002]

BACKGROUND OF THE INVENTION Irrigation water, for example drinking water, is expected to be in short supply worldwide in the future. In countries that consume drinking water, desalination plants are installed to supply the drinking water. However, desalination plants generally have high installation and operating costs. In addition, there are environmental problems in securing the installation location and operating the desalination plant.

[0003] Therefore, it is conceivable to transport water for use by sea by tanker or the like, but tanker transport is too costly. On the other hand, it has been studied to transport water in large-capacity bags.

[0004]

In order to transport a large amount of service water in a large-capacity bag and transported by sea, the bag containing the service water must be floated on the seawater. For this reason, an air reservoir is provided in the bag to provide buoyancy. However, the provision of the air reservoir reduces the space for storing the water and reduces the transportation efficiency of the water. On the other hand, storing water on the ground must solve the problem of storage facilities and locations.

It is an object of the present invention to be able to transport or store a large amount of water on water.

[0006]

In order to solve the above problems, the present invention provides a structure having a space for storing water,
An object lighter than water attached to the structure, and a water-impermeable covering member for covering the structure and the lighter object, so that the water can be transported or stored by floating on the water. It is characterized by becoming.

By doing so, the water can be stored in the space of the structure. By attaching an object lighter than water to the structure, buoyancy can be imparted to the structure storing water. By covering the structure and an object lighter than water with a covering member that is impermeable to water, the structure storing the water can be floated. further,
The stored water is prevented from leaking to the outside of the covering member. At the same time, water outside the cover member can be prevented from entering the water side. Therefore, the structure storing the water is floated on the water so that the water can be transported or stored. By using the present floating body device, water can be transported over sea or lake water or stored on sea or lake water.

If the structure has a space for storing water, the structure is integrally formed as a whole, a plurality of substructures are connected, or a plurality of unit members (made of a lightweight material) are used. It may be a combination of “unit members” described later). Further, the structure may have a strong rigidity with a small deformation, or a structure or a rigidity capable of deforming flexibly. The degree of rigidity of the structure is appropriately selected according to the material to be used, use conditions, and the like.

It is preferable that the structure is divided into a plurality of blocks by partitions. During the transportation or storage of water, even if the outer wall of one block is damaged and the water stored in the block spills out or the outside water infiltrates and this water becomes unusable, the water in other blocks will not be usable. Secured. further,
By providing a partition in the structure and dividing the structure into a plurality of blocks, movement of water due to tilting of the structure during transportation or storage is prevented, and stability of the floating body device is secured.

[0010] When the structural members are formed by connecting the unit members, the shape of the unit members may be a frame shape, a box shape, a container shape, or a shape in which a columnar portion is projected from a base as described below. . In particular, in the case of a box shape, a container shape, and the like, it is preferable to provide a through hole in the side wall of the box shape, the container shape, or the like so that water can move between the unit members. In short, the unit member has a space inside which communicates with the outside, and can have an appropriate shape as long as it has necessary strength or rigidity. In the structure, since unit members having a small weight are assembled, connection construction of the unit members is easy. Therefore, the structure can be assembled in a short time. In addition, an object lighter than water may be provided along the outside of the structure. Since an object lighter than water is provided outside the structure, the structure is protected and buoyancy can be imparted to the structure.

The unit member has a base having a flat surface on one side and a columnar portion protruding from the other side of the base, and the structure connects the bases and the tips of the columnar portions to each other. I hope you do it. Since the bases of the unit members are connected to each other, the flat surfaces of the base and the edges of the base are connected. Furthermore, since the tips of the columnar portions of the unit members are connected to each other, the columnar portion is located between the bases, and a space for storing water is formed. By connecting the unit members in this manner, the entire structure is formed by stacking the unit members in a plurality of stages and expanding in a plane, so that a three-dimensional three-dimensional structure can be formed.

Further, it is preferable that the structure has a recess that opens upward. After transporting the irrigation water to the destination and transporting the irrigation water, the burrs of the structure can be loaded and the burrs can be transported.

The water for use is not particularly limited, such as drinking water, emergency water, or water containing specific components. An object lighter than water is a synthetic resin, for example, a synthetic resin foam such as styrene, an air mat, or the like. Also, an object lighter than water may be attached along the outer surface of the structure, but the inside of the structure, for example, by forming a columnar portion into a cylindrical shape,
The cylindrical hollow portion may be filled. Furthermore, as an object lighter than water to give buoyancy to the structure, a protective material lighter than water, that is, a protective sheet such as a nonwoven fabric, may be used to surround the outer surface of the structure. The covering member is not particularly limited as long as it is impermeable to water, but is preferably, for example, a synthetic rubber sheet or a metal plate having excellent corrosion resistance to water.

The unit member is preferably made of a lightweight material having strength and rigidity. By making the unit members have rigidity, it is possible to easily make the structure assembled therefrom also have rigidity. In addition, since one unit member is light in weight, it can be easily transported and assembled in a short time. Examples of the material of such a unit member include a synthetic resin such as polypropylene, a light metal such as an aluminum alloy, lightweight concrete, and the like. In particular, a material having corrosion resistance to water is preferable.

The unit member may have a base and a columnar portion as described above. It is preferable that the base of the unit member has an edge connecting portion provided near the edge of the base. By using an edge connecting member that can be engaged with the edge connecting portion, the bases are connected via the edge connecting member. The shape of the base is not particularly limited as long as one side has a substantially flat surface and the other side has a columnar portion protruding. For example, a rib structure having a plate member and an edge frame provided on the other side along the edge of the plate member, and further reinforcing ribs provided between the edge frames is preferable.

This reduces the weight of the base and reduces the amount of material used. The shape of the plate member may be, for example, a polygon such as a square or a rectangle. The edge connection portion provided near the edge of the base is, for example, an engagement hole (or engagement hole) provided on a substantially flat surface on one side of the base, and the edge connection member is provided with an engagement hole. Projections may be provided. The position where the edge connecting portion is provided is preferably near the edge. In particular, when the plate member is rectangular, holes or projections may be provided at the four corners. By using the edge connection portions provided at the four corners and the edge connection members engaging with the edge connection portions, the connection can be made in a state where the corners of the eight unit members at the top and bottom are gathered at one point.

[0017] The base may have a through hole through which one side and the other side pass. When storing water, it allows water to move through this through hole.

The outer cross-sectional shape of the columnar portion of the unit member is not particularly limited, but may be circular or polygonal. Further, it is preferable that the columnar portion is formed in a cylindrical shape.
The columnar portion formed in a tubular shape is lightweight, rigid, and excellent in load resistance. In particular, it is preferable that the columnar portion is formed in a cylindrical shape whose diameter gradually decreases toward the tip. By doing so, when transporting or transporting the unit members, it is possible to transport and transport by overlapping the cylindrical columnar portions of several unit members, and it is possible to improve transport and transport efficiency.

The number of columnar portions projected or extended from the base is one or more. In particular, when four pillars are projected, a stable multi-stage structure can be obtained. The columnar part may have an end connecting part at this tip. By using an end connecting member that can be engaged with the end connecting portion, the ends of the columnar portions can be connected via the end connecting member. The end connecting portion may be provided with, for example, an engaging hole (or an engaging hole) on the tip end surface of the columnar portion, and a protrusion engaging with the engaging hole may be formed on the end connecting member side. When the columnar portion is cylindrical or cylindrical, the position of the engagement hole of the end connecting portion provided at the tip of the columnar portion is provided at an appropriate position on the circumference thereof.

The porosity or porosity S of the unit member, ie, S = (V1-V2) / V1, where V1: the volume of one member forming the space V2: the mass is converted from the mass of one member forming the space The larger the volume, the better, but if the porosity S is too large, the load resistance to a load applied from above and the strength to a load applied from the side may be reduced.

The upper limit of the space ratio S is up to 97%. Conversely, if the space ratio S is small, the strength of the member can be increased, but the volume occupied by the member increases, and the space formed by the columnar portion decreases. The size, thickness, etc. of the base and the columnar portion should be large enough to support the load applied to the structure. It is preferable in terms of manufacturing that the materials of the base and the columnar portion be the same.
