Description

Submerged Artificial Reef as Shelter of Sea Creatures Including Sea Cucumber}

The present invention relates to a submerged agent, and more particularly, to a submerged agent having a function of a habitat for marine organisms including sea cucumbers.

The environment of the East Sea of Korea was very barren to inhabit sea cucumbers along the coast, unlike the environment of the West Sea. On the other hand, seabed erosion in the East Sea is reaching a very serious point.

Various organic matters are mixed in coastal soil and sand, and the types of aquatic organisms that feed on them are very diverse. In particular, sea cucumbers live by eating organic matter from soil and sand, and seaweed erosion is the result of removing the food from sea cucumbers. Therefore, in order to inhabit sea cucumbers and protect individuals, it is essential not only to provide shelter for sea cucumbers to be protected from natural enemies, but also to provide an environment in which sea cucumbers' food can be continuously supplied.

In addition, the strong waves injure or kill soft-skinned marine creatures such as sea cucumbers. In other words, if sea cucumbers swept by the waves hit the hard reefs around them and are injured or killed, it is difficult to protect the sea cucumbers in the water.

For sea cucumbers, the purpose is not to simply preserve the individual, but it is important that the sea cucumbers must reproduce and inhabit in an environment where it is easy for humans to collect sea cucumbers. In other words, the coast is barren to inhabit, and if a deeper seabed becomes a more suitable environment for sea cucumbers to live, the sea cucumbers gradually move to the seabed and inhabit, making it difficult to collect sea cucumbers.

Therefore, the habitat for the habitat of sea cucumbers should not be hard, the sea cucumbers and their species should not be swept away by tide or waves, and the sea cucumbers should be continuously supplied around the habitat, so that food for sea cucumbers should be supplied continuously. In particular, the protection of the sect is a very important factor. On the other hand, if continuous seabed sedimentation is induced, not only sea cucumber food is continuously supplied, but also coastal erosion can be prevented.

A plurality of submerged units of the present invention are connected and installed to function as submerged units (see FIGS. 8 to 10). In addition, by using the principle that floating matter in the seawater settles inside the submerged unit as ocean currents are dissipated, the submerged unit can be used as a habitat for marine organisms such as sea cucumbers by utilizing the fact that organic matter can be constantly supplied to the submerged unit. Use it as a point.

In particular, sea cucumbers can live by eating organic substances that have sunk on the surface of stone due to their habits, but since it is difficult to eat organic substances from pure sand, the submerged unit of the present invention is very useful as a habitat for sea cucumbers.

1 to 7, the submerged unit of the embodiment according to the present invention is made of a base 20, a side mesh 30, a longitudinal box 40, and a stone 50.

[Base]

Hereinafter, a base will be described with reference to FIGS. 1 to 3. The base 20 provides a flat bottom surface.

The base 20 may include a frame 21 including an outer frame 211 and an inner frame 212 made of a metal material. The outer frame 211 may have a square frame shape. The outer frame 211 may be manufactured by cutting a section steel or a square tube into a predetermined length and connecting each other to form four sides of a square. The shape of the section steel or each tube may vary. For example, the outer frame may be made of a "ㅁ"-shaped square tube or a "a" shaped steel. The inner frame 212 may have a shape connecting members corresponding to each side of the outer frame 211 to each other. The inner frame 212 may be a member of a "+" shape or a "#" shape disposed in the outer frame 211. The inner frame 212 may also be made of a section steel or a square tube.

The outer frame 211 and the inner frame 212 may be manufactured by fixing the square pipes or sections to each other by bolting or by fixing them by welding or the like.

The base 20 may include the outer frame 211 and the bottom mesh 22 installed on the inner frame 212. The floor mesh 22 may be made of a metal mesh such as metal lath or steel lath. The bottom mesh 22 may have a square shape, may be placed on the inner frame 212, and its edge may be fixed to the outer frame 211. The bottom mesh 22 may be fixed to the inner frame 212 or may be placed on it. The edge of the bottom mesh 22 and the outer frame 211 may be welded. The bottom mesh 22 may be fastened in a fastening manner using a fixing member 23 (see FIG. 4) including a washer, a bolt, and a nut instead of or with the welding. That is, the bolt penetrates the bottom mesh, but a washer inserted into the bolt presses the bottom mesh, so that the bottom mesh is fixed to the outer frame 211.

Referring to FIG. 6, a lifting ring 29 may be installed on the outer frame 211. The lifting ring may be installed on the outer frame 211 at a portion where the outer frame 211 and the inner frame 212 are connected to each other. That is, the lifting ring 29 may be fixed to the edge of the base 20 and exposed to the outside.

In addition to this, the base 20 may be configured by an extension base 60 (see FIG. 11) to be described later. That is, the upper end of the extension base 60 may replace the function of the base 20. The lifting ring 29 may be installed on the extension base 60.

[Side mesh]

1 to 5, the side mesh 30 is installed on the base 20 so as to extend upward from the edge of the base 20. That is, the lower end of the side mesh 30 may be fixed to the edge of the base 20. Referring to FIG. 4, in detail, the lower end of the side mesh 30 may be fixed to the outer frame 211. The lower end of the side mesh body 30 is welded and fixed to the external frame 211 by overlapping or overlapping with the edge of the mesh body 22 (or fixed), and the external frame ( 211) can be fixed.

The side mesh 30 may use a mesh having the same structure as the bottom mesh 22 or a different mesh. Since steel lath or metal lath has no welding area, it can reduce rust intensively on the welding area in seawater.

The side mesh body 30 may have a rectangular plate shape, and may be installed on the base 20 in a form in which the lower end is erected while being fixed to the base 20. The side net body 30 may have a rectangular shape elongated laterally. The bottom surface of the base 20 has a square shape, and the side mesh body 30 may be formed of four mesh bodies having a left and right rectangular shape.

Edges of the first side mesh body 30-1 and the second side mesh body 30-2 adjacent to each other of the four side mesh bodies may overlap each other to form an overlapping portion 303. The overlapping portion 303 may increase the width of the overlapping portion from the base to the top so that the side mesh body 30 may be inclined toward the base. That is, the overlapping portion 303 may have a triangular shape erected so that the pointed vertex portion is downward. By adjusting the length at which the upper portions of the overlapping portions 303 overlap, the degree of inclination of the side mesh body 30 inward may be adjusted. The longer the overlapping length of the upper portion of the overlapping portion 303 is, the more inclined the side mesh body 30 may be.

[Backing member]

1 to 3 and 5, the inner side of the overlapping portion 303, that is, near the boundary between the overlapping portion 303 and the portion where the side mesh body 30 does not overlap, the overlapping portion 303 ) May be installed to support the overlapping state.

The backing member 31 may be an elongated rectangular plate made of a metal material. A plurality of fastening holes 311 may be formed in the backing member 31 at predetermined intervals along the length direction. A pair of backing members 31 are formed by interposing both sides of the overlapping portion 303 between the pair of backing members 31 and fastening the fastening members 32 through the fastening holes 311. By compressing the corresponding part of 303), the overlapping portion 303 can be firmly supported without a separate welding operation, and the side mesh body 30 when filling the stone material 50 to be described later You can resist the force you receive in the direction that opens. The fastening member 32 may be a conventional bolt, nut, washer, or the like.

In addition, the backing member 31 supports the overlapping portion 303 with a widely distributed compression force in a state that is not fixed to the base 20, which is the same as a rigid body, so even if an external force acts in the direction of spreading the overlapping portion 303 , External force is appropriately distributed and supported by the pair of backing members, and accordingly, a phenomenon in which a load is concentrated and damaged in one part can be minimized.

The base 20 and the side mesh 30 define the inner space A of the submerged unit 10. The inner space A may have a square truncated shape. Since the backing member 31 supports the overlapping portion 303 of the side mesh body 30 in a state that is not fixed to the base 20, the square truncated cone shape may have a particularly flexible side structure to some extent.

[Death]

Referring to FIGS. 1 to 3 and 7, a longitudinal box 40 is installed in the central portion of the inner space A. The seed box 40 provides a safe space for the chisam to inhabit, thereby increasing the survival rate of the chisam. The seed box 40 may be made of a metal plate. The lower end of the longitudinal box 40 may be fixed to the base 20. The lower end of the longitudinal box 40 may be fixed to the frame 21, more specifically to the inner frame 212, through welding and/or fastening means such as bolts and nuts.

The longitudinal box 40 may be in the shape of a hollow square column extending vertically. Specifically, the longitudinal box 40 may include sidewall portions 41 extending vertically. The side wall part 41 has the same shape as a square tube. The opening provided at the upper end of the side wall part 41 may be covered by the upper surface part 42. In addition, a door 422 capable of opening and closing the inner space of the longitudinal box 40 may be installed on the upper surface portion 42. When the door 422 is opened, the hollow portion of the longitudinal box 40 may be opened upward.

Meanwhile, holes 411, 412, and 413 having different sizes and/or shapes through which marine organisms such as sea cucumbers can enter and exit may be formed in the side wall part 41.

A plurality of first holes 411 having a first area may be formed on the sidewall part 41 at a predetermined interval. Further, a plurality of second holes 412 having a second area larger than the first area may be formed under the sidewall part 41 at a predetermined interval. In addition, a third hole 413 having a long hole shape extending laterally may be formed in the central portion of the side wall portion 41. In addition, a plurality of fourth holes 421 having a size corresponding to the first hole 411 may be formed in the upper surface portion 42.

The first hole 411 and the fourth hole 421 may have a size such that tooth ginseng can enter and exit. The third hole 413 may have a size such that sea cucumber, which is an adult, can also enter and exit.

The second hole 412 may have a size such that ocean currents can smoothly enter and exit the hollow portion of the longitudinal box 40.

[stone]

Referring to FIGS. 1 and 7, the inner space A of the submerged unit 10 is filled with stone. The size of the stone may be such that it does not pass through the side mesh body 30 and the floor mesh body 22. The size of the stone may be 0.00001 m ³ /EA (a cubic volume having a side length of about 2 cm) or more. If the size of the stone is smaller than this, the pores are not sufficiently formed, making it difficult for the stone to retain food for sea cucumbers, and it may not be easy for sea cucumbers to move. In addition, the size of the stone may be less than 0.05 m ³ /EA (a cubic volume with a length of about 35 cm on one side). If the size of the stone is larger than this, the pores will become larger than necessary, making it easier for marine organisms to access sea cucumbers.

The stone 50 is filled in the remaining inner space ( A ) except for the seed box. In addition, the stone 50 may fill a part of the inner space A.

The stone 50 may be filled by 1/3 to 2/3 of the height of the inner space A. More preferably, the stone 50 may be filled by 1/2 of the height of the inner space A.

The stone materials 50 filled in the inner space ( A ) are in contact with the side mesh body 30 on the outside, and the central portion in contact with the longitudinal box 40. Even if the plurality of stone materials 50 receive an external force by the ocean current, the load is distributed by itself, and the load can be further distributed by the side mesh body 30 in which the edge portion of the side is flexibly fixed by the backing member 31. have. As such, the stone 50 supports the lower part of the seed box 40 while dispersing or dissipating the current, so even if only the lower end of the seed box 40 is fixed to the base 20, the phenomenon that the seed box 40 is damaged. It can be prevented enough.

In addition, the stone 50 supports a predetermined section under the backing member 31. Accordingly, the backing member 31 can maintain its posture. For example, even if an external force in the direction in which the backing member 31 lies down toward the inner space is applied, or if an external force is applied in a direction extending outward, by the supporting force of the stone 50 and the tension of the side mesh 30, the backing member ( 31) It is possible to maintain this posture. In other words, the side mesh body 30 is able to maintain a flexible erected state by the backing member 31 not fixed to the base 20.

The first hole 411 and the third hole 413 may be positioned above the stone filled in the inner space and exposed to the outside of the stone, and the second hole 412 is located under the stone filled in the inner space. It may be placed and not exposed to the outside of the stone.

The upper space (a) in which the stone material 50 is not filled in the inner space ( A ) becomes a space in which sea cucumbers exiting from the seed box 40 can grow on the stone for a certain period of time.

The ocean current passes through the space between the stones 50 having a predetermined void, and the flow velocity is lowered. Accordingly, the drift sand mixed with the ocean current passes through the wire mesh and sinks in the void of the stone.

Since the side mesh body 30 is inclined inward, even if the two submerged units 10 are installed adjacent to each other, a space through which an ocean current can flow is formed between the two submerged units 10. Therefore, even if a plurality of submerged units 10 are clustered and mounted, seawater can smoothly flow to the submerged unit 10 therein.

[rope]

8 to 10, a rope 70 through which seaweed can be transplanted may be connected to the side net body 30. The rope 70 may be in the form of a net having a net, or may be in the form of a rope. The rope 70 is very strong in tension and easy to transplant seaweed.

Therefore, the submerged units 10 are formed by mounting on the sea floor, but when the side nets 30 of neighboring submerged units are interconnected with the rope 70, a solid submerged structure as a whole can be constructed. The submerged units 10 may be connected by a net-shaped rope 70 and/or may be connected by a plurality of rope-shaped ropes 70 extending parallel to each other.

The side net body 30 may be in a flexible state because its upper end is not connected to a separate rigid structure. Therefore, when the centers of the upper ends of the side nets 30 of the two submerged units 10 are connected to each other with the rope 70, the side nets may open outward. However, if the two side nets 30 of one submerged unit 10 are connected together, it may not be easy for a diver to access the submerged unit 40 or the inner space A.

Accordingly, the rope 70 may be connected to the overlapping portion 303. Of course, since it is in the form of a mesh, a portion to which the rope 70 can be connected is provided in the overlapping portion 303. 8 illustrates a structure in which the rope 70 is connected to the upper portion of the overlapping portion 303. The overlapping portion 303 is stronger because at least two side meshes 30 are overlapped, and the backing member 31 provides additional support, so that the rope 70 can be firmly supported.

Of course, the present invention excludes connecting the middle of the upper ends of the side nets 30 of the two submerged units 10 to each other with a rope 70 and connecting the two side nets 30 of one submerged unit 10 together. Is not.

In addition, if a living seaweed seedling is directly tied to a net and transplanted with a thread, or if it is attached to the side net body 30, it can be attached and grown well. Therefore, the submarine structure formed by mounting a plurality of the submerged units 10 may be formed as a submarine forest, so that a ranch where abalone and fry can live well may be formed.

[Extended base]

On the other hand, if the submerged unit is installed on the bottom of the sea, such as the west coast, the submerged unit may settle. Accordingly, an extension base 60 may be further installed in the submerged unit 10 as shown in FIG. 11. The extension base 60 may have a rectangular parallelepiped shape extending downward by a predetermined depth from the edge of the base 20. The height (depth) of the extension base 60 may be determined according to a result of evaluating the quality of the soil on the sea floor. That is, if the extension base 60 is configured by predicting the depth at which the submerged units will settle, the upper part of the base 20 is exposed to the outside even if the submerged units settle, so that a desired purpose can be achieved.

The extension base 60 may be a gabion or gabion in the form of a rectangular parallelepiped filled with stone material therein. The extension base 60 in the shape of a gaebion may be installed under the frame 21 of the base 20. The upper frame of the extension base 60 may share the frame 21 of the base 20. That is, the frame 21 of the base 20 may be an upper frame of the extension base 60.

Alternatively, the extension base 60 may be a concrete block. When the extension base 60 is composed of a concrete block, the upper end of the extension base 60 may form the base 20. That is, when the extension base 60 is made of a concrete block, the frame 21 and the floor mesh 22 of the base 20 may be omitted, and the upper surface of the extension base 60 may be utilized as a frame. At this time, the lower end of the side mesh 30 and the lower end of the longitudinal box 40 may be fixed to the upper surface of the extension base 60 through an anchor or the like. In addition, in the process of curing the concrete block, it is also possible to integrally manufacture the lower end of the side mesh 30 or the lower end of the seed box 40 to be buried. The longitudinal box 40 may have a separate bottom, or the extension base 60 may form the bottom of the longitudinal box 40.

According to the above-described invention, the seed box 40 becomes a place for discharging the chisam, and the inner space ( A ) and the upper space (a) of the submerged unit 10 become a habitat for sea cucumbers. Food can be supplied naturally. Nutrients or food may be periodically added to the seed box 40 to promote the growth of tooth ginseng.

In addition, as the plurality of submerged units 10 are connected with the rope 70, an underwater structure may be formed, and seaweeds may be attached to the rope 70 and the side mesh body 30 and transplanted to form a submarine forest. Marine forests can provide a good environment for fry and abalone. In addition, the rope 70 may provide a site for cultivating algae such as kelp in coastal structures.

In addition, since it can be produced by adjusting the size of the base of the extension base 60 according to the soil quality, there is no problem of sedimentation, so that the function of the submerged material can be faithfully performed. The submerged structure may be installed at the boundary of the fishing village system. In addition, it can function to prevent seabed erosion by blocking the path of movement of dianthus.

As described above with reference to the drawings illustrated for the present invention, the present invention is not limited by the embodiments and drawings disclosed in the present specification, and various by a person skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can be made. In addition, even if not explicitly described and described the effects of the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effects of the configuration should also be recognized.
