BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copper alloy cage net,

In the present invention, a first cage net made of a synthetic fiber material is formed on the upper part, and a second cage net made of a copper alloy material is provided on the lower part, thereby preventing marine adhered creatures such as barnacle or seaweeds from adhering to the mesh, The present invention relates to an overturning cage apparatus using a copper alloy and a method of manufacturing the same, which can prevent the marine adventitious creatures from interfering with the bird communication of the cage net by blocking the mesh.

Abalone, which has been loved for its excellent texture and nutrition, has been continuously increasing in demand despite its high price. Abalone, which is loved by people not only in Korea but also in the world, belongs to the Haliotidae and Haliotis, and lives in coasts of temperate, tropical and subtropical regions all over the world. Haliotis discus hannai, Haliotis discus discus, Haliotis madaka, and Haliotis gigantea are the most abundant species in Korea. have.

Abalone is known to be effective for prevention of obesity, protection of liver, recovery of fatigue, protection of eyesight and prevention of myocardial infarction because of high protein content and low fat content. Abalone, which is recognized as a high quality aquatic product, is called a shellfish emperor. It is traded at a high price in aquatic products, and its value is recognized because of increasing demand not only in domestic but also overseas like China and Japan. However, the amount of offshore abalone has been decreasing due to overfishing of overcrowded biomass and industrialized urbanization, while the abalone aquaculture industry occupies 53% of the total shellfish production of 560.3 billion won in 2014, It is growing.

As abalone farming techniques were established in the 1980s, abundant farming methods were developed from choral to cage farming to terrestrial farming. Particularly, sea cage methods are being used to make cages in the sea, and to feed seaweed and kelp in the seaweeds and artificial houses.

Recently, however, the fishery environment of marine caged fishery, which is the most abalone fishery, is getting worse. The marine cages, which are installed in the offshore waters around the West Sea and the South Sea, are experiencing worsening of the aquaculture environment due to poor distribution of seawater due to erosion, seaweeds used as feeds, and compound feed residue. As a result, the mortality rate is high and productivity is rapidly decreasing.

In addition, aquaculture facilities are damaged due to weather changes such as typhoons that come from the seasons. Most of the marine cage facilities are constructed by enclosing a mesh in a frame with a skeleton below the water surface. These structures are connected at regular intervals, and the upper frame including the scaffolding is connected to the bottom of the scaffold, And the lower abalone part is configured to be located 2 to 3 m below the surface of the water. These maritime cage devices are rope-secured to the sea floor.

Under the web of the abalone farming area, abalone attaches to the structure which can grow, and when feed such as seaweed, kelp, etc. is supplied, the food waste or abalone excrement passes through the net and is released to the bottom of the sea floor. Most of the abalone marine cage facilities are installed in dense waters near the sea, making it difficult to circulate clean water because the birds are stagnant and the communication is not smooth. As a result, the amount of dissolved oxygen in the farms is also lowered, which deteriorates the farming environment. In other words, it is inevitable that the aquaculture will receive the damage of environmental pollution caused by the aquaculture facility

In addition, the conventional abalone cage net is made of chemical fiber and plastic, and if left in the sea for a long time, there is a problem that marine adhered creatures block the mesh. The use of antifouling paint on the net or the use of a plastic net with less marine organisms was attempted. However, the antifouling paint not only increased the marine pollution on the bottom of the cage farm, but also affected the growth of abalone. I am using a net.

Therefore, in recent years, it has been attempted to manufacture a cage made of a copper alloy, which is not attached to any marine organisms, in the case of a cage network that cultivates fishes domestically and externally. Korean Patent No. 10-1358180 discloses a patent relating to a manufacturing method of a cage net using a copper alloy net, but the prior art is formed in the form of a chain link net, and the mesh is used as a mesh size It is difficult to make it small and there is a disadvantage that it contains a lot of cost and material. In addition, since abalone is an attached organism, it lives on the abalone house or directly attached to the net. Therefore, when living in contact with the copper alloy network, there is a possibility that the growth rate may drop due to stress or the like.

In Korean Patent No. 10-1358180, a PE pipe is formed by forming a square upper frame (subframe, reinforcing frame) such as a circular or main cage frame into one line and connecting it with a copper alloy to be inserted into the main cage frame, And a reinforcement plastic frame is reinforced on the bottom to prevent the bottom copper alloy net from being hung down due to its own weight. The present invention relates to a method of manufacturing a cage net using a copper alloy net.

In Korean Patent No. 10-1341945, a plurality of reinforcing piles are arranged in a vertical direction at regular intervals from the outer periphery of the cage main body, and the reinforcing pile is moved along the reinforcing pile in the up and down direction together with the cage main body And the center rope of the bottom of the cage main body is connected to a floating sphere floating on the water surface by the adjustment rope, and the adjustment rope is provided with a "∪" shaped movement path by a tension bar provided on the lower side of the reinforcing pile Thereby enabling stable settlement and floating operation of the cage main body while keeping the shape of the cage main body to a maximum, thereby minimizing the stress or injury of cultured fishes due to distortion of the cage main body, deformation such as overlapping or leaning At the same time, natural disasters caused by high and strong waves or typhoons Which can greatly prevent the damage of the cage main body and the economic loss due to the escape of the cultured fish, can be prevented in advance. Korean Patent Registration No. 10-1172032 discloses a method for manufacturing a fish, comprising: a plurality of bottom members arranged horizontally and vertically so as to constitute a movement path of an operator while partitioning a space for culturing fish; A plurality of bonding members for connecting the plurality of bottom members to each other so that the bottom member forms a frame having a predetermined shape and a plurality of floats fixed to the bottom of the bottom member so as to float on the surface of the plurality of bottom members and the bonding members; Wherein the bottom member, the joining member and the float are composed of a fiber-reinforced composite material.

In order to solve the above-mentioned problem that a conventional copper alloy cage network has a high manufacturing cost and an increase in merchandise or mortality when an abalone is adhered, a first cage net of a synthetic fiber material is formed on the upper side of the side panel The lower part of the side plate is formed with a second cage net made of copper alloy and the lower plate provided with the abalone housing in which abalone lives is formed with a third cage net made of synthetic fiber material And to provide an overturning cage apparatus using the copper alloy to be installed.

In addition, when the side plate is formed of a copper alloy network, it is not as flexible as a fiber net. In the nature of the abalone cage, the worker enters the inside of the net to install the abalone house, and the abalone house must be collected again at the harvest time. ≪ / RTI >

Conventional cage aquaculture apparatuses are constructed such that a net having a skeleton below the water surface is surrounded by a net and these structures are connected at regular intervals, and the upper frame including the footplate of the structure is connected to the bottom of the footplate by styrofoam, And the lower overturned part is configured to be located 2 to 3 m below the water surface, and this marine cage device is rope-secured to the sea floor.

However, when the mesh is formed of synthetic fibers such as polyethylene and is installed in the sea for a long period of time, a large amount of shellfish and seaweed that are inhabited in seawater are adhered to prevent seawater communication inside the cage, There is a problem that the lack of dissolved oxygen causes massive death of aquaculture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an abalone grinding apparatus using the copper alloy of the present invention and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.

1 shows a perspective view of a rollover cage apparatus using the copper alloy of the present invention. The overturning cage apparatus using the copper alloy of the present invention has a polygonal chemical fiber upper frame (10) installed on the upper part; An intermediate frame 20 is installed at a predetermined distance from the upper frame; A first cage net (30) is formed surrounding the space between the upper frame and the middle part; A lower frame 40 spaced downwardly from the intermediate frame by a predetermined distance; A second cage net (50) is formed in the space between the intermediate frame and the lower frame; The lower frame 60 may be formed in the lower frame.

The upper frame and the intermediate frame may be formed of a material or structure capable of maintaining a frame shape in water or underwater by a pipe or a rigid rope structure. The upper frame and the intermediate frame are spaced apart from each other by a predetermined distance. The first frame may surround the spacing space.

It is appropriate that the height of the first cage net according to the present invention, that is, the distance between the upper frame and the middle frame, is formed to a water level higher than a water level of the water surface or a substantial living space of the attached creature or shelter.

Since the first cage net is formed of a synthetic fiber material as described later, marine life such as a barnacle can be adhered after a certain time after installation in seawater, which may interfere with the flow of birds into the cage net, In order to prevent damage to the apparatus.

The first cage net 30 of the present invention is a cage net used for a conventional marine cage, and is formed of a synthetic fiber material. The term synthetic fiber referred to in the present invention refers to a synthetic fiber obtained by chemically reacting a raw material such as natural gas, air, water, oil or fat, a plant or the like, and polymerizing the low molecular weight compound with a high molecular weight compound, And may be formed of a material selected from at least one of polyester, polyvinyl alcohol, polyvinyl chloride, and polyethylene.

The lower frame may be installed at a predetermined distance from the lower portion of the intermediate frame. The lower frame 40 is formed in the same structure as the upper and middle frames and surrounds the spacing space between the middle frame and the lower frame, and a second cage net is provided, and a lower net is formed on the inner side of the lower frame. The above structure stores at least one aquaculture organism and forms an internal aquaculture facility where a plurality of shelters to which aquaculture organisms adhere can be installed.

The second cage net 50 of the present invention is a copper alloy composed of a composite material of copper (Cu), zinc (Zn), manganese (Mn), nickel (Ni), tin (Sn) . Therefore, it is excellent in strength and resistant to corrosion, so it can be applied not only to the inner cage but also to the outer sea. In addition, it can reduce management cost compared to chemical fiber network and reduce netting damage and breeding environment deterioration, and it can improve productivity by promoting cultured fish growth rate due to its antibacterial property, and also has high reuse rate, There is an advantage that it can be reduced. The horizontal and vertical corners forming the surface of the second cage network can be fixed by a snapping method and can be fixed in a spring-fastened manner by snapping the mesh and the mesh.

Fig. 2 shows an enlarged view of the second cage network of the present invention. The second cage network of the present invention may be formed of the copper alloy material described above and may include a mesh network 51 forming a frame structure of a constant diameter of the cage network and a mesh network 52 formed inside the mesh network.

The mesh of the present invention comprises a horizontal mesh network formed by one or more horizontal and vertical meshes, and a vertical mesh network vertically intersecting the mesh meshes to form square or rectangular woven netting or crimp. The mesh is formed into a square or a rectangle so that it has superior tidal currents as compared with a mesh of a typical rhombus shape and has excellent durability such that deformation does not occur even in the current flow.

In the case where the horizontal to vertical mesh networks are formed with concave portions at regular intervals and the horizontal to vertical mesh networks are crossed up and down, the horizontal or vertical paints are accommodated in the recessed structure, so that the mesh is pushed out of the existing weave, It is possible to prevent the shape from being deformed.

As shown in FIG. 2, the finishing of the climbing net is finished by bending the end line of the horizontal line and the next line to the concave portion of the vertical line and bending the cut portion of the vertical line. Then, the portion contacting the fiber net is wound with the sling band, Do not wear out.

The planar area of the second cage net according to the present invention is formed to be smaller than the planar area size of the first cage net, so that the overturning cage apparatus according to the present invention is formed into a structure having a vertical sectional shape in which the width of the horizontal cross- do. When the overturning cage apparatus of the present invention is stored in a ship or on land before being installed in the sea, the second cage network is formed of an alloy material that maintains its shape, and the first cage network is formed of a synthetic fiber material having a flexible frame form, If it is formed to have the same or smaller size than the second cage net, the second cage net is overlapped with the synthetic fiber net, and the shelter and the net formed therein are entangled and can be lost.

Therefore, when the size of the first cage net is larger than that of the second cage net and is located at the bottom of the water deck outside the sea, the first cage net is prevented from entering the inner opening formed by the second cage net The net can be prevented from being entangled or broken by spreading it to the outside of the second cage net.

The lower network is formed of the same structure and material as the first network. Typically, the abalone style is made up of at least one house (shelter) where abalone can live in a rectangular cage net and provides food such as seaweed or kelp. Also, the living radius of abalone in the cage is the shelter, the bottom net, and the side net on all sides, the most active radius being the base of the abalone house and the net.

The copper alloy is a material that is not suitable for direct attachment of the abalone, which is an adhered creature, and the subnetwork according to the present invention is formed of a synthetic fiber material in which the abalone is inhabited mainly, Can be prevented from falling.

In the case of the second cage net formed on the side of the whole structure, it is formed as a climatic form of copper alloy material, minimizing attachment of marine organisms, thereby facilitating communication of algae inside the cage during installation in the ocean for a long time, Improvement is possible. The first cage net minimizes the cost of production when the entire cage is formed of a copper alloy material and minimizes the biostresses in the cage by reducing the resistance due to external forces such as waves by using synthetic fibers at a portion of the upper net The durability of the copper alloy network can be enhanced.

Fig. 3 shows Embodiment 1 of an overturning cage apparatus using the copper alloy of the present invention. In the first embodiment according to the present invention, the first cage net is 0.5 to 1 meter in height, and the second cage net made of copper alloy is a climbing net, and the side plate is 1.5 to 2 meters in height. , And the second cage net is not folded but always maintains the vertical shape, so that the operator can not easily go in and work. Therefore, the side door 100 may be formed on one side of the side wall of the second cage net so that the operator can enter the second cage net.

The door is difficult to enter into the cage network when stocking into the cage network or harvesting after the cage network. The entrance door is an inner cage network which not only facilitates shelter and aquaculture hatching, Workers can get inside without having to dismantle the device.

The door may be formed in the form of a hinged door in the horizontal or vertical direction, and the hinge fixing the door may be formed by spring-connecting some of the edges of the climbing net and the hinged door which form the second rim network.

Figs. 4 to 6 show a second embodiment of a rollover cage apparatus using the copper alloy of the present invention. The second cage net of the present invention has a crimped structure made of a copper alloy and is difficult to bend flexibly as a net formed of conventional synthetic fibers. In the second embodiment according to the present invention, a square net or a rectangular net is provided, a second net is connected to one side of the lower net, and a second net is formed in the middle of each side of the second net, The hinge device 200 can be installed to fold the cage net like a book (Figs. 5 and 6). The foldable foldable hinge is formed by spring-connecting the edges of the climbing net made up of the two sides of the second cage net divided into two sides (Fig. 5).

The hinge device according to the present invention is formed of a copper alloy spring structure, one side of a second cage net is connected to one side of the lower net 4, and both side ends of the at least one second cage network are connected via a fixing device such as a rope .

Accordingly, when the fixing device is released, the overturning cage apparatus according to the present invention may be in the form of being unfolded on the floor. Therefore, when the operator collects the overturning cage apparatus of the present invention on the ground or the work line as shown in Fig. 6, it can be easily operated or stored inside the cage.

Fig. 7 shows a photograph of an overturning cage apparatus using the copper alloy of the present invention. When a fixed rope is provided on the overturning cage apparatus of the present invention, the first cage net and the second cage net are developed upward and downward to form a cage shape when installed in water.

7 is a side view of the second cage net formed by a copper alloy net, which is different from FIGS. 5 to 6, and is divided into upper and lower heights so that small squares can be vertically stacked inside the large squares. Accordingly, when the cage apparatus is lifted from the sea above the deck and the worker is working, the square plate of the upper copper alloy net is vertically overlapped on the outer side of the square side plate of the lower copper alloy net constituting the second cage net, . In FIG. 7, a side plate formed by the second cage net is divided into upper and lower portions, so that a lower copper alloy net overlaps the upper copper alloy net and is formed.

The fixed rope is connected to the edge of the first ridge net, and when the fixed rope ridge is lifted up, the upper copper alloy net overlapped with the lower copper alloy net separated by the upper and lower ridges rises along the edge of the lower copper alloy net The upper and lower copper alloy chains can be lifted and transferred to the water by being joined to the connecting device formed at the lower end of the upper copper alloy network and the upper end of the lower copper alloy network. In this case, the side faces of the lower net constituting the second cage network are not fixed to each other,

≪ Experimental Example 1 > Effect of installing abalone cage device

8 is a photograph showing an installation of an overturning cage apparatus using a copper alloy according to an experimental example of the present invention. Experimental Example 1 was conducted in order to confirm the effect of installing the abalone cage apparatus using the copper alloy of the present invention in seawater. The experiment was carried out in Wando fishing grounds, and it was installed in September 2017, Confirmed in November.

FIG. 9 shows a process of performing a confirmation operation in November 2018 according to an experimental example of the present invention, and FIG. 10 shows an abalone harvested after culturing according to an experimental example of the present invention. As a result, mortality rate of the copper alloy was significantly decreased in the copper alloy compared to 30 ~ 50% in the case of abalone mortality, but it was 10 ~ 20 % Growth.

In the case of a conventional aquaculture apparatus installed in the sea, a marine creature such as a barnacle or seaweed adheres to a cage net by time, thereby obstructing the communication of the cage net by blocking the mesh, It is possible to prevent an increase in the incomes of fishermen because it is possible to prevent the degradation of the growth rate or to reduce the growth rate and to prevent the marine garbage from being thrown after using the device as compared with the conventional cage apparatus formed of a copper- It is possible to provide an environmentally superior future-oriented aquaculture device, which is industrially applicable.
