Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an artificial floating island, and more particularly to an artificial floating island having a structure in which a plurality of floating islands are connected and integrated.

[0002]

2. Description of the Related Art Conventionally, it has been generally practiced to install artificial floating islands in lakes and marshes and to vegetate aquatic plants such as reeds to purify the water quality of the lakes or to maintain the landscape.

As shown in FIGS. 8 and 9, for example, an artificial floating island of this type includes a plurality of small floating islands 50 (unit floating islands 50).
Are connected to each other to have a desired size or shape, and the periphery thereof is moored via a chain 51 to an anchor 52 such as a concrete block submerged in a lake bottom or the like.

In this case, the number of moorings and mooring points on the artificial floating island, that is, the number of anchors 52 and the position where the chain 51 is tied to the floating island are determined by the size of the floating island and the size of the floating island so as to prevent displacement and inundation of the floating island. The shape and the environment of the lake, for example, the wind direction, the wave, the flow, or the shape of the lake bottom are determined in consideration of the shape.

[0005]

In the above-mentioned artificial floating island, the size of the floating island is changed later by increasing or decreasing the number of unit floating islands, for example, for the purpose of water purification. If a floating island is provided, reduce the unit floating island and reduce the floating island when the water quality of the lake improves, and conversely, if there is no improvement in the water quality, increase the unit floating island and expand the floating island Is performed.

However, if the size of the floating island is changed by increasing or decreasing the number of the unit floating islands as described above, the mooring balance of the floating island may be disrupted. For example, as shown by a dashed line in FIG. It may be necessary to change the mooring position with the increase.

In such a case, in addition to the work of adding unit floating islands, a work of changing the mooring position is required, and an excessive amount of labor is required for the worker.

The present invention has been made to solve the above problems, and has as its object to provide an artificial floating island mooring structure whose size and shape can be freely changed by simpler operations.

[0009]

In order to solve the above-mentioned problems, the present invention relates to an artificial floating island comprising a plurality of unit floating islands connected to each other at an arbitrary center position and at least three directions from the center position. A rope extending radially along the surface of the water is provided, and a float is connected to a tip of each rope to moor each float, and a unit floating island is connected to the rope, and the unit floating island is connected to the rope. (See claim 1).

[0010] In this case, since the ropes moored via the floats form a framework, even if the number of unit floating islands is increased or decreased, the mooring balance of the entire artificial floating island is not easily impaired. Therefore, the size and shape of the artificial floating island can be easily changed only by attaching and detaching the unit floating island without changing the mooring location and the number of mooring as in the conventional artificial floating island of this type.
Further, since the cords are provided in at least three directions, the displacement of the artificial floating island can be effectively suppressed even when the water level of a lake or the like falls. In consideration of the structure of the artificial floating island, the installation work, and the effect of preventing movement when the water level is lowered, it is most practical to provide the above-mentioned cords in the cross direction (claim 2).

In the artificial floating island, a unit floating island may be connected to the cord as the float (Claim 2), or the unit floating island may be provided at the center at the center, and If the base end is connected to this unit floating island (claim 3), the number of unit floating islands can be increased. In particular, providing a unit floating island as a float is advantageous in maintaining the landscape.

[0012] In the description of the claims, "cord strip"
The meaning is that a chain or the like is included in addition to a so-called wire rope.

[0013]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic plan view showing an artificial floating island of the present invention, and shows a state where the artificial floating island is installed on the water surface of a lake or marsh. The artificial floating island 10 shown in the figure is provided for the purpose of purifying the water quality of a lake, and as shown in the figure, a cross-shaped mooring base 12 floating in the water surface is used as a framework. A large number of unit floating islands 24 are connected, and aquatic plants such as reeds are planted on each unit floating island 14.

As shown in FIG. 2, the mooring base 12 is
A unit floating island 14 and floats 16 arranged at regular intervals in the direction of a cross with the unit floating island as a center,
The unit floating islands 14 and the respective floats 16 are connected to each other via wire ropes (cored strips) 18.

Each float 16 is formed of a material having a sufficient buoyancy. As shown in FIG. 3, an anchor 22 made of a concrete block or the like submerged in the lake bottom is used.
Is moored via a chain 20. Float 16
Mooring of anchor 2 in consideration of the water level of lakes and marshes
2, the length of the chain 20 and the like are set, and thereby each wire rope 18 is given an appropriate tension. In addition, mooring of the float 16 may be performed using a wire rope instead of the chain 20, for example, as necessary.

The unit floating island 14 provided at the center of the mooring base 12 has the same structure as the other unit floating islands 24 connected to the mooring base 12, and in this embodiment,
The unit floating islands 14 and 24 are configured as follows.

As shown in FIG. 4 and FIG.
4 and 24 have an annular metal frame 30 at the lowermost part, and a cylindrical float member 34 formed in a regular hexagonal shape in a plan view on the upper part of the frame 30. The float member 34 is formed of a material having a sufficient buoyancy such as, for example, foamed polyethylene, and is fixed to the frame 30 by bolts and nuts. A connection hook 31 is provided around the frame 30, and a mooring hook 32 is provided at the bottom.

On the other hand, above the float member 34, a vegetation base 36 made of synthetic fiber is provided. The vegetation base 36 is, as shown in FIG.
5 is provided so as to intervene from the periphery thereof, thereby forming a vegetation space 38 of a plant recessed from the surface (upper surface) in the center of the unit floating island 14. And
In this vegetation space 38, aquatic plants (not shown) such as reeds are planted on the vegetation base 36.

That is, in a state where the unit floating islands 14 and 24 are installed on the water surface, the bottom of the unit floating islands 14 and 24 is appropriately set below the water surface by the balance between the buoyancy of the float member 34 and the weight of the frame 30 and the vegetation base. 36 is immersed in the water surface, so that the water necessary for growing the aquatic plants planted on the vegetation base 36 is supplied from the lake.

As shown in FIG. 1, the unit floating islands 24 configured as described above are connected to the unit floating islands 1 of the mooring base 12.
4 or the mooring base 1 connected to the wire rope 18
The unit floating islands 24 are connected to each other around the mooring base 12 in such a manner that the unit floating islands 24 are further connected around the unit floating islands 24 connected to the artificial floating islands 10. In this case, each unit floating island 24 is
As shown in the drawing, each side wall of the unit floating island 24 is parallel to the wire rope 18 and the adjacent unit floating island 2
The four side walls are connected so as to correspond to each other.

The unit floating island 24 with respect to the mooring base 12
Or the unit floating islands 24 are connected to each other by using the connecting hooks 31 provided on the unit floating islands 14 and 24 via a rope, a chain or the like. Although not shown, the adjacent unit floating islands 14 and 2
A cushioning material made of urethane foam or the like is interposed between the four as required, so that damage due to collision between unit floating islands can be prevented.

According to the artificial floating island 10 configured as described above, the unit floating islands 24 are sequentially connected to the cross-shaped mooring base 12 moored to the anchor 22 as described above. As long as the area is within a circle having a radius from the unit floating island 14 to the float 16 with the twelve unit floating islands 14 as the center, even if the unit floating island 24 is increased or decreased, the mooring balance of the artificial floating island as a whole is hardly impaired. .

Therefore, when the size of the artificial floating island 10 is changed according to the state of the water quality of the lake, the unit floating island 24 with respect to the mooring base 12 or the unit floating island 24 already connected to the mooring base 12 is used. By simply attaching and detaching the floating island 24, the size and shape of the artificial floating island 10 can be changed without changing the mooring location, the number of moorings, and the like of the artificial floating island 10. Therefore, when comparing the size and shape of the artificial floating island 10, it is extremely easy to change the size and shape of the artificial floating island 10 as compared with the conventional artificial floating island of this type, which often involves changes in the mooring points and the number of moorings when the size of the artificial floating island is changed. It is possible to greatly reduce the labor required for such a change operation.

The structure of the artificial floating island 10 described above is one embodiment of the artificial floating island according to the present invention,
The specific structure can be appropriately changed without departing from the gist of the present invention.

For example, in the mooring base 12 of the artificial floating island 10 of the above embodiment, floats 16 are arranged in four directions around the unit floating island 14, and these floats 16 and the unit floating island 14 are connected by wire ropes 18. However, as shown in FIG. 6, floats 16 are provided in three directions around the unit floating islands 14 and
The float 16 may be provided in at least five directions around the unit floating island 14, and these may be connected to the unit floating island via a wire rope 18, though not shown. The mooring base 12 connected to the base 14 may be configured. In short, unit floating island 1
The mooring base 12 may be configured so that the floats 16 are provided in at least three directions around the center 4 and are connected to the unit floating islands 14 by the wire ropes 18.

That is, for example, as shown in FIG. 7, two floats 16 are connected by a wire rope 18 and a mooring base 12 'for mooring the float 16 to an anchor 22 so as to apply an appropriate tension to the wire rope 18. In this case, when the water level of the lake drops and the mooring chain 20 receives a wind or a wave from a specific direction under a loose state, specifically, from a direction orthogonal to the wire rope 18. When wind or the like is received (indicated by an arrow in the figure), the mooring base 12 is deformed as shown by a broken line in the figure, and the entire artificial floating island moves largely. However, when the floats 16 are provided in three or more directions and are moored to the anchor 22 as in the present invention, the floats 16 are moored in three or more directions. One of the chains 20 effectively works, whereby the deformation of the mooring base 12 is suppressed. Therefore, the movement of the artificial floating island can be effectively suppressed. Therefore, in the structure of the mooring base 12, it is necessary to provide the floats 16 in at least three directions as described above, and to connect them to the unit floating islands 14 with the wire ropes 18. In consideration of the structure of the mooring base 12, the mooring operation, the effect of preventing the movement of the artificial floating island 10, and the like, it is most practical to form the cross-shaped mooring base 12 as shown in FIG.

Further, the mooring substrate 12 of the artificial floating island 10 described above.
In the above, the floats 16 are connected to the unit floating islands 14 via the wire ropes 18 and the floats 16 are moored to the anchors 22. For example, the unit floating islands 14 are provided instead of the floats 16 and the unit floating islands 14 are moored. You may. In this way, the number of unit floating islands 14 constituting the artificial floating island 10 can be increased, and this is also advantageous in maintaining the landscape of the lake. Conversely, a float 16 may be provided instead of the unit floating island 14 at the center. In addition,
Depending on the scale of the artificial floating island 10, it is not always necessary to provide the unit floating island 14 or the float 16 at the center of the mooring base 12, and for example, by adopting a structure in which two wire ropes cross each other, the unit floating island 14 at the center, etc. May be omitted. However, in this case, the wire ropes need to be connected not only at the center position of the mooring base 12 but also at the center position. Note that, in the configuration in which the unit floating island 14 at the center is omitted as described above, when the scale of the artificial floating island 10 is increased and the distance from the center of the mooring base 12 to the float 16 or the like is increased, the wire rope 18 is likely to sink. When constructing a large artificial floating island 10, the wire rope 18
It is desirable to provide a unit floating island 14 and a float 16 at the center of the mooring base 12 in order to prevent sinking of the water.

Further, the mooring substrate 1 of the artificial floating island 10 described above.
2, the distance from the unit floating island 14 to each float 16 is set to be equal.
Different lengths may be set so that 0 is obtained. Also, in the mooring base 12, the floats 16 are arranged in the cross direction, so that the wire ropes 18 are stretched around the unit floating islands 14 at circumferential intervals of 90 degrees. However, this angle may be appropriately selected so that the artificial floating island 10 can be stably installed.

Further, the specific structure of the unit floating islands 14 and 24 and the method of mooring the unit floating islands 24 to the mooring base 12 are not limited to the example of the artificial floating island 10 of the above embodiment, and a desired artificial floating island 10 can be obtained. The configuration or selection may be made as appropriate so that it can be performed.
