Description

CONCRETE ARTIFICIAL FISH REEF

The present invention relates to an artificial fish candle, and more particularly, to a concrete artificial fish candle providing a living environment for aquatic organisms.

Artificial ground reef is an artificial structure that is installed in the sea to create an environment in which aquatic organisms such as seafood and seaweed can be inhabited. It is mainly installed in a sea of 10 to 50 m in depth and gently flows the sea water It is known that the density of marine organisms in the places where artificial fishes are installed is 3 to 4 times higher than that of natural fisheries, as it plays a role of providing spawning grounds by gathering fishes and also acts as an obstacle.

Therefore, artificial fishes are used for the purpose of protecting the fisheries from the trawler with a great fishing ability and the fishing net, and fostering fishery resources by creating spawning grounds and hiding places for various fishes and shellfishes.

On the other hand, in recent years, due to marine pollution and rising water temperature, the frequency of occurrence of the back rust (whitening phenomenon) is becoming frequent. The whitening phenomenon is a phenomenon in which calcium carbonate floating in a solid state precipitates in the seawater and becomes white as a result of scattering of the incident light due to the scattering of the incident light. The calcium carbonate floating in the sea gradually precipitates, So that seaweeds and fish and shellfish are killed and the coastal bottom layer is devastated.

In order to overcome the above-mentioned problem, in order to provide spawning grounds and habitat for abalone, sea urchin and sea urchin such as abalone, sea urchin, and sea urchin which feed seaweeds in the sea floor, Research on technology is underway.

Therefore, it is required to develop an artificial fish which has a simple manufacturing process and is free of corrosion when exposed to seawater and easy to activate seaweeds.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

FIG. 1 is a perspective view showing the construction of the artificial ear candle 100 according to the present invention, and FIG. 2 is a sectional view showing a sectional structure of the artificial ear candle 100.

The artificial fish candle 100 according to the present invention includes a plate-shaped lower structure 110, a central structure 120 protruding from the upper center of the lower structure 110 and having a central passage 121, Side structures 130 and 130a coupled to both sides of the upper surface of the lower structure 110 and having side passages 131 formed therein and a loop structure 140 protruding from the outer circumference of the central structure 120. [

Here, the artificial fish candle 100 according to the present invention is integrally manufactured through concrete, and has a simple manufacturing process and strong durability.

The substructure 110 is formed in a horizontal plate shape so as to be in contact with the sea floor. The lower structure 110 may be formed in a rectangular shape, a circular shape, or the like, and may have various other shapes.

Although not shown in the drawing, the lower structure 110 may be inserted through one or more spikes so as to be in contact with the sea floor and to be easily fixed to the seabed of sand or the like.

The central structure 120 protrudes from the central upper surface of the lower structure 110 to provide a space for marine life to enter and exit. The central structure 120 has a central passage 121 formed therein.

Here, both surfaces of the central structure 120 may be formed in a trapezoidal shape having an inclination angle. At this time, both sides of the central structure 120 are formed at an inclination angle of 3 ° to 45 ° so that the amount of sunshine at the upper and lower portions of the artificial ear candle 100 can be constant. When the angle of inclination of the both side inclined surfaces of the central structure 120 is less than 3 degrees, the sunlight is blocked by the upper part of the artificial ear 100 and the amount of reaching the lower part is insignificant so that it is difficult to form the sea water in the lower part of the artificial ear 100, When the angle is greater than 45 °, there is a problem that formation of another structure is difficult, and both sides of the center structure 120 can be formed at an inclination angle of preferably 3 ° to 45 °, more preferably 5 ° to 30 ° .

On the outer circumferential surface of the central structural body 120, concavo-convex grooves 123 are formed at regular intervals along the longitudinal direction. The uneven grooves 123 facilitate the activation of seaweeds and prevent slippage. When algae are deposited on the uneven groove 123, it can be used as a hideout for fishes or octopuses.

The side structures 130 and 130a are disposed on both sides of the upper surface of the lower structure 110 to provide a living space for marine life. A side passage 131 is formed in the middle area of the side structures 130 and 130a.

The side structures 130 and 130a may be circular or arc shaped. At this time, the side structures 130 and 130a provided on both sides may have different diameters, though they may have different shapes or same shapes.

For example, the side structures 130 and 130a formed on both sides of the upper surface of the lower structure 110 may have a diameter of 20 cm and 30 cm, respectively, so that the habitat space can be separated according to the size and species of marine life .

Side surface irregular grooves 133 are also provided on the outer circumferential surfaces of the side structures 130 and 130a to facilitate seaweed migration.

The loop structure 140 may include a loop structure 140 protruding from the outer surface of the central structure 120 and the side structures 130 and 130a. The loop structure 140 is looped so as to capture a fishing net of a fishing net or a fishing net fishing boat with one or more fixedly connected to the outer circumferential surface of the central structure 120.

The lower portion of the loop structure 140 is embedded in the central structure 120 by the coupling means 141.

By providing the loop structure 140, it is possible to protect the fishing ground and to provide spawning grounds and hiding places for various fishes and shellfishes.

.

In addition, a plurality of vertical passages 125 and 135 may be provided on the surfaces of the central structure 120 and the side structures 130 and 130a. The seawater can freely flow through the vertical passages 125 and 135 into the inner space of the artificial fish pond 100.

As a result, it is possible to provide a habitat as a vegetation space of aquatic plants and fish such as seaweeds, and to smooth the flow of ocean currents encountered on the surface of the artificial fish.

In some cases, a mesh network (not shown) including yellow soil may be provided inside the central structure 120 and the side structures 130 and 130a. The mesh network (not shown) has an effect of maximizing the surface area of the artificial fish pellets 100 without interfering with the passage of the fishes, thereby helping the seaweeds to grow.

3 is a cross-sectional view illustrating a cross-sectional configuration of an artificial fish 100a according to another embodiment of the present invention.

As shown in the figure, the artificial fish pail 100a according to another embodiment is provided with a scattering groove 150 formed at an inner wall surface forming the central passage 121 and formed with a certain depth toward the outside of the central structural body 120. The scattering grooves 150 provide more habitat for fish to be habituated or hiding, and can further increase the area of attachment, which is the habitat for attached organisms.

Particularly, the artificial aqueduct 160 is inserted into the scattering groove 150 to provide an optimal environment for scattering. The artificial aquatic plant 160 is formed in the form of fibers that can naturally flow into the water stream. For this purpose, the artificial ear 160 may be embodied as nylon, loess, fiber, microfiber, film, vinyl, or the like.

The artificial aquarium 160 is attached and fixed to the wall surface of the scattering groove 150. At this time, it is difficult to directly attach the artificial aquatic plant 160 to the inside of the central structure 120 formed of concrete. To this end, the inner wall surface of the scattering groove 150 may be thermoplastic resin or thermosetting resin to easily join the artificial aqueduct 160.

A plurality of artificial aquatic plants 160 are provided in the scattering grooves 150 to maximize the scattering efficiency of fishes, shellfishes and octopus fishes, and to increase the adhesiveness and scattering properties.

The artificial fish candle 100 according to the present invention is manufactured using concrete. The artificial ear candle 100 may be manufactured by placing and curing concrete in a mold having a skeleton corresponding to the shape of the lower structure 110, the central structure 120 and the side structures 130 and 130a.

Here, the artificial fish candle 100 according to the present invention can be applied to an echo concrete in which a coarse aggregate having a large particle size is used as a skeleton and the use of fine aggregate is restricted to secure a void in concrete. This eco-concrete has permeability and durability due to innumerable micro spaces. It enhances the rate of early seeding and germination of seaweeds and is suitable for growth and reproduction of fish by living in small space. Compared with the case of the reared fish.

In addition, eco-concrete is an eco-friendly biomedical concrete that has the basic mechanical properties of vegetation function and concrete, so that it can function smoothly. In addition, it minimizes the environmental burden and has a pollution-free and acid-proof nature, thus fulfilling its role as an artificial fish candle.

As described above, the artificial fish weeds according to the present invention are combined with the central structure and the side structure on the upper part of the lower structure to form various types of habitats. In addition, since it is formed of a concrete material, the durability can be improved and the manufacturing process can be simplified.
