It is an invention about.

The devastation of coastal fishing grounds is worsening due to the phenomenon of coastal greening. Whitening refers to the disappearance of foliate seaweed in various shapes and colors from coastal rock areas, where white calcareous algae proliferates, causing rocky areas to dry out. It means turning white.

When this phenomenon of coastal greening occurs, marine forests disappear, which not only leads to the destruction of ecosystems such as fish spawning grounds and juvenile fish breeding grounds, resulting in the depletion of fishery resources, but also reduces edible seaweed such as kelp and seaweed, which is a major blow to fishermen's income source. will be given.

Therefore, as one of the measures to overcome the recent coastal greening phenomenon and restore the ecosystem, a sea forest creation project using marine forest reefs is being actively promoted. The sea forest creation project involves directly transplanting seaweed into marine forest reefs, which are artificial structures within the coastal green areas. By creating a marine forest using various methods, such as seed transplantation, to create an environment suitable for the habitat, spawning, and growth of aquatic life, it not only increases the productivity of fishing grounds with reduced productivity by attracting coastal sessile aquatic life as well as migratory fish. Rather, it is a project being carried out for the purpose of improving the fishing environment.

More specifically, the marine forest used to create a marine forest is intended to create a marine forest, that is, a sea forest, by growing various types of seaweed seedlings on plates or ropes installed on a reef frame. The biggest problem with such marine forest is that This means that seaweed seedlings growing on plates or ropes are eaten by predatory animals such as conches and sea urchins before they grow beyond a certain size.

Feeding damage by these predators is a major cause of preventing the creation of marine forests, and is pointed out as a problem that must be solved in order to restore marine ecosystems devastated by coastal greening and at the same time prevent pollution of coastal waters.

In this regard, Japanese Patent Laid-Open No. 09-285250 (1997.11.04) discloses a cone-shaped insectivore prevention tool installed on the surface of an artificial reef.

Japanese Patent Publication No. 09-285250 discloses an insectivorous damage prevention tool consisting of an installation part attached to the surface of an underwater structure for creating a marine forest such as a marine forest plant, and a theater part that is provided radially from the installation part to prevent the entry of predatory animals. is disclosed, but the insectivorous pest prevention tool disclosed in the above-mentioned Japanese published patent has a limitation in that it is difficult to effectively prevent predatory animals from climbing onto marine forest plants.

Next, there is Registered Utility Model No. 20-186775 (April 11, 2000), which relates to a simple artificial reef and does not disclose any structure that can prevent predators from climbing, such as the present invention or the above Japanese published patent. There is a clear difference in that it is not there.

Therefore, there is a need for a predatory animal access prevention device that can be easily installed by divers and can effectively prevent the ascent of predatory animals.

An insertion groove 120 is formed at one point of the insertion portion 110, and a fixing portion 400, which will be described later, can be inserted into the insertion groove 120. A detailed explanation of this will be provided later.

At one end of the main body 100, a first defense part 200 is formed extending in the longitudinal direction, and the first defense part 200 and the main body 100 form a predetermined angle and the first defense part 200 is preferably formed inclined toward the direction in which the insertion portion 110 is formed.

In order to prevent predators from approaching the marine forest, the first defense unit 200 is preferably made of a light and hard material, for example, copper, ceramic, aluminum, nickel, titanium, plastic, etc. You can.

In other words, the first defense unit 200 is effective in preventing the approach of relatively small predatory animals.

At the other end of the main body 100, a second defense part 300 is formed extending in the width direction, and the second defense part 300 and the main body 100 form a predetermined angle and the second defense part 300 is preferably formed inclined toward the direction in which the insertion portion 110 is formed.

A protrusion 311 is formed at one end of the second defense unit 300, and the 2-1 defense unit 310 is coupled to the protrusion 311. At this time, the second defense unit 300 is made of a hard material like the above-described first defense unit 200, and the 2-1 defense unit 310 is made of a flexible or elastic material such as rubber or silicon. It is desirable.

That is, after a relatively large bird-feeding animal passes the first defense unit 200, it approaches the second defense unit 300, and when the bird-feeding animal hangs on the 2-1 defense unit 310, the weight of the bird-feeding animal Therefore, it cannot pass through the 2-1 defense unit 310.

In other words, the second defense unit 300 is effective in preventing the approach of relatively small predatory animals.

After extending an imaginary line in the direction perpendicular to one end of the main body 100, the angle between the main body 100 and the first defense part 200 is set to 'a', and the angle between the main body 100 and the second defense part 200 is set to 'a'. The angle between the defense units 300 is referred to as 'b'.

At this time, it is preferable that the angle (b) between the main body 100 and the second defense unit 300 is smaller than the angle (a) between the main body 100 and the first defense unit 200, and the first defense unit ( 200) and the second defense unit 300 serve to block predators approaching the midsea forest reef.

That is, the first prevention unit 200 primarily blocks access by predatory animals, and the second prevention unit 300 secondarily blocks access by predatory animals.

Figure 2 is a plan view from the top of the device for protecting the marine forest ecosystem from invertebrates that eat seaweed according to the present invention.

The first defense portion 200 is formed in plural pieces at one end of the main body portion 100, and is preferably formed in a radial shape. The second defense portion 300 is formed in plural pieces at the other end of the main body portion 100 and is preferably formed in a radial shape. It is preferable to be formed as

In addition, it is preferable that the number of the first defense units 200 and the second defense units 300 are the same, for example, the number of the second defense units 300 is greater than the number of the first defense units 200. If is less or more, blocking access of predatory animals may not be performed effectively because one of the steps of primarily blocking access to predatory animals and the secondary blocking step is skipped.

Figures 3 and 4 show how the present invention blocks the approach of the predatory animals when they approach the marine forest reef.

Figure 3 shows a case where a relatively large predator approaches the first defense unit 200 and the second defense unit 300.

The bird-feeding animal located at one end can be seen trying to pass through the first defense unit 200, and the bird-feeding animal located at the other end passes through the first defense unit 200 and then passes through the second defense unit 300. You can see the shape you are trying to achieve.

That is, when the feeding animal located at the other end tries to pass through the 2-1 defense unit 310, the flexibility and elasticity of the 2-1 defense unit 310 and the weight of the feeding animal cause the 2-1 defense unit 310 to ), you can see that it does not pass.

Therefore, according to an embodiment of the present invention, the plurality of first defense units 200 and the plurality of second defense units 300 block the path of the predatory animals or prevent the predatory animals from climbing onto the complex ecological block or seabed seedbed. In this case, it can provide a blocking function such as bending under the weight of the feeding animal to prevent it from rising further and dislodging the attached feeding animal by the flow of the ocean current.

Figure 4 shows a case where a relatively small bird-feeding animal approaches the first defense unit 200 and the second defense unit 300.

The bird-feeding animal located at one end can be seen as having failed to pass through the first defense unit 200 due to the first defense unit 200, and the bird-feeding animal located at the other end can be seen passing through the first defense unit 200 and then passing through the first defense unit 200. 2 It can be seen that it cannot pass through the defense unit 300 and thus cannot approach the mid-sea forest.

In other words, it is difficult for birds of a relatively small size to pass through the first defense unit 200 and the second defense unit 300 and access the marine forest reef, and in creating a marine forest in the sea, it is difficult for the bird-feeding animal to pass through the first and second defense units 200 and 300. This has the advantage of effectively preventing them from climbing up and eating.

Therefore, according to an embodiment of the present invention, the first defense unit 200 and the second defense unit 300 have a structure in which the first defense unit 200 and the second defense unit 300 surround the mid-sea forest reef. If the path of the feeding animal is interrupted or the feeding animal comes up on the first defense unit 200 and the second defense unit 300, it may be bent by the weight of the feeding animal to prevent it from going up any further.

In addition, it provides a blocking function such as dislodging predatory animals attached to the first defense unit 200 and the second defense unit 300 by the flow of the ocean current, thereby protecting the ecosystem such as marine forest plants created on the upper part of the marine forest structure. It can be protected from predatory animals such as sea urchins.

Referring to Figure 5 (a), the hook 510 is formed toward the bottom, and referring to Figure 5 (b), the hook 510 is formed toward the top.

In other words, when connecting the main body 100 to a complex ecological block or an underwater forest structure, the hook 510 can be used, and the part where the main body 100 should be installed can be selected and installed, so that it can be installed by selecting the part where the main body 100 should be installed. It is possible to prevent the main body 100 from being separated from the underwater forest reef structure.

In addition, when the main body 100 is formed on a flat surface such as a seabed seedbed or a composite ecological block, the hanging portion 500 can be easily installed and released depending on the underwater environment, and the length of the separately provided hook 510 can be adjusted by the operator. It has the advantage of being able to be easily changed depending on the underwater environment.

In addition, the angle at which the hook 510 is formed is not uniform, but can be easily changed depending on the underwater environment, thereby increasing convenience of use.

Figure 6 shows a shape in which a plurality of first defense units 200 and second defense units 300 according to the present invention are combined.

The block 10 shown in FIG. 6 is preferably the above-described composite ecological block, and when a plurality of body parts 100 are formed on the surface of the block 10, the insertion groove formed in the insertion part 110 ( The fixing part 400 can be inserted into the interior of 120 so that the plurality of main body parts 100 are positioned on the same line.

At this time, the fixing part 400 is preferably formed of a metal such as stainless steel, stainless steel, or copper, and is formed of a flexible material because a plurality of body parts 100 must be connected and fixed to the block 10. It is desirable.

If the block 10 is installed as shown in FIG. 6, even if the first defense unit 200 and the second defense unit 300 are installed densely, when the block 10 is viewed in the width direction, the A space is created between the first defense unit 200 and the second defense unit 300, and this space allows sea urchins to invade.

Therefore, when the block 10 is installed, it is preferable that the first defense unit 200 is located at the bottom and the second defense unit 300 is located at the top, as shown in FIGS. 3 and 4.

In addition, due to the locking portion 500 formed on the other side of the main body 100, it can be installed not only on the simple square block 10, but also on underwater forest reefs and seabed seedbeds of various shapes. There is.

In addition, it is effective in preventing the approach of predatory animals while allowing divers to easily install it regardless of the specific shape of the underwater forest plant.

Next, Figure 7 shows the shape of the device for protecting the underwater forest ecosystem from invertebrate herbivores that eat seaweed according to the present invention coupled to the underwater forest structure 600.

Specifically, the underwater forest reef is formed on the upper part of the underwater forest reef structure 600, and a plurality of pillar parts 610 are formed by extending in the vertical direction at the lower part of the underwater forest reef structure 600.

The main body portion 100 may be coupled to the pillar portion 610, and in this case, the first defense portion 200 is preferably formed to be positioned vertically lower than the second defense portion 300.

That is, when an avian animal attempts to approach the underwater forest reef structure 600 along the pillar portion 610, the approach of the avian animal can be blocked by the first defense unit 200 and the second defense unit 300.

In Figure 7, the number of main body parts 100 coupled to one pillar part 610 is shown as one or two, but the number of main body parts 100 coupled to one pillar part 610 is not limited to this. , For example, the main body portion 100 may be formed along the outer peripheral surface of the pillar portion 610.

Therefore, as the number of main body units 100 increases, the number of first defense units 200 and second defense units 300 also increases, making it possible to block access to predators more effectively.
