Description

FISH FARMING CAGES

The present invention relates to a cage farm.

In general, a sea cage farm refers to a facility that installs a cage net within a certain range of waters such as coastal waters or open seas and grows various fish within it. In most cases, a scaffold structure in the form of a rough "田" is manufactured to provide a space and a passage, and then a buoyant body is connected to the lower part of the scaffolding structure, and the cages are connected along the inner circumferential surface of the scaffolding structure.

As seawater inside and outside the cage passes freely through the mesh of the cage, the exchange of seawater and the supply of oxygen are made smoothly, and wastes and feed debris generated in the process of metabolism of aquaculture fish are also automatically discharged to the outside through the cage. Therefore, it is widely used in large-scale aquaculture due to the advantage of not deteriorating the quality of water inside the street net even if a large amount of fish is farmed at high density.

On the other hand, natural disasters such as red tides and typhoons may occur in the sea area where such a cage farm is installed. Red tide is a natural phenomenon in which the color of seawater changes to red, yellow, reddish brown, etc. due to the mass reproduction of phytoplankton. Phytoplankton rapidly consumes the amount of dissolved oxygen in the water, secreting a large amount of mucus, and the mucus adheres to the fish gills to block the supply of oxygen, resulting in collective death of fish. Red tide appears only when ocean currents and tidal currents do not communicate well and a marine environment suitable for mass propagation of red tide organisms such as sunlight, water temperature, salinity, and nutrients is created.

These natural phenomena had a problem that aquaculture companies had to endure huge economic losses.

In order to solve such a problem, it is most desirable to move the cage farm itself to a safe place such as the inner port side of the breakwater or the water body where the red tide does not flow using a ship when a red tide occurs.

However, the cage net itself becomes a large-sized net bag having a cylindrical or polygonal shape, so while the cage is moved using a vessel, the cage is excessively pulled in the direction opposite to the towing direction of the vessel, and the cage is deformed There was a problem that this largely occurred.

In addition, in the process of moving the position of the cage by using a ship, excessive pull of the cage occurs, and the internal space of the cage becomes relatively very narrow, and the farmed fish trapped inside the cage is subjected to considerable stress. Fish body damage occurred as aquaculture fish swept on the surface of the cage or collided with each other, and when such stress and damage were severe, a serious problem of mass death of farmed fish occurred.

Conceived on the basis of the above technical background, the present invention is to provide a cage farm that improves the frictional power of an anchor so that it can be fixed more stably in the water while preventing the drift of the cage so that it can be moved more easily. do.

A cage farm according to an embodiment of the present invention, a cage frame located at the top of the buoyancy body and connected to the cage frame, a guide portion located inside the cage frame and having a locking member connected to the cage cage, and the cage frame It may include an elevating portion connected to the guide portion from the upper portion to raise and lower the guide portion.

In addition, it is connected to the guide frame, it may further include an anchor having a weight body in which a plurality of protrusions are formed on the outer surface.

In addition, the guide portion may be formed in a grid-like frame shape by cross-connecting a plurality of guide members in a grid structure.

In addition, the locking member may have one end connected to an intersection point at which the guide member is cross-connected, and the other end connected to the cage rig.

In addition, the elevating portion, by rotating the wire rope connected to the rim of the guide portion, the drum on which the wire rope is wound, and the drum in one direction or another direction, to wind or loosen the wire rope to the drum to raise the guide portion And a driving unit that descends.

In addition, the weight body may include an insertion groove in which a cross-sectional area decreases toward the inside is formed on the bottom, and a protrusion in which a cross-sectional area decreases as the cross-sectional area decreases is formed at an upper portion thereof.

The cage farm according to an embodiment of the present invention prevents excessive tilting of the cage net when moving, so that when a red tide occurs, it can easily move to a nearby water area where damage does not occur, thereby preventing damage caused by the red tide. , It can improve the friction of the anchor so that it can be fixed more stably in the water.

The anchor 190 may be connected to the other end of the mooring rope 107, so that the cage frame 100 may be fixed at a certain place by the anchor 190. At this time, the anchor 190 may be seated on the sea floor while being connected to the cage frame 100 through the mooring rope 107.

Figure 2 is a side view of the buoyancy body according to an embodiment of the present invention, Figure 3 is the other side view of the buoyancy body according to an embodiment of the present invention.

2 and 3, a buoyancy body 110 may be connected and installed on the lower surface of the frame 100.

A metal bar-shaped reinforcing member 101 may be disposed on the lower surface of the border frame 100, and the reinforcing member 101 is integrated with the border frame 100 by an overlay layer 103 formed with a predetermined thickness. Can be formed. The overlay layer 103 may be formed over the surface of the reinforcing member 101, and the buoyancy body 110 is engaged with the reinforcing member 101 including the overlay layer 103 and the lower surface of the frame 100 It can be connected and installed integrally with.

The buoyancy body 110 has a cylindrical shape having an internal space and may store ballast water 117. For example, the buoyancy body 110 may have a cylindrical shape having a "∪" shape in cross section. As another example, the buoyancy body 110 may be formed of a polymer resin material such as polyethylene (PE) or fiber-reinforced plastic (FRP). The buoyant body 110 made of a polymer resin material is light and sturdy, and at the same time has excellent corrosion resistance, so that it can well withstand external impacts received in seawater.

The buoyancy body 110 has a first partition wall 112 disposed in the horizontal direction to partition the storage space of the ballast water 117 in the lower inner side, and the ballast water in the storage space at one lower side of the buoyancy body 110 ( An injection valve 115 for injecting 117 may be connected and installed, and a check valve 119 may be installed at an upper portion of one side.

At this time, at least one second partition wall 113 extending in a direction perpendicular to the upper surface of the first partition wall 112 may be installed on the inner upper portion of the buoyancy body 110. Accordingly, since the inner space of the buoyancy body 110 is partitioned by the second partition wall 113, even if a crack or breakage occurs in a part of the buoyancy body 110, seawater does not flow into the entire inner space of the buoyancy body 110. May not. In addition, a connection groove 111 may be formed on the outer upper surface of the buoyancy body 110 so that the reinforcing frame 101 of the cage frame 100 may be engaged and coupled to each other.

For example, the check valve 119 may be composed of a check valve 119 for inflow of external air and a check valve 119 for discharge of internal pressure, and accordingly, the condensation phenomenon inside the buoyancy body 110 and the corresponding internal pressure In addition to the drop, it is possible to prevent an increase in internal pressure of the buoyancy body 110 due to an external high temperature phenomenon.

Referring to FIG. 4, the guide part 150 may include a guide member 151 and a locking member 155.

The guide member 151 is formed in a rod shape and may be made of a metal material. For example, the guide member 151 made of metal may be coated with a polyvinyl chloride (PVC) coating layer on its outer surface.

The guide member 151 made of metal is excellent in mechanical strength and durability, so even if it is disposed in seawater, it can withstand impacts such as ocean currents or waves, and corrosion resistance is improved by the coating layer to prevent corrosion to seawater.

A plurality of guide members 151 may be cross-connected to each other to form a closed frame shape having a lattice structure. For example, the guide unit 150 is formed in a grid structure by a plurality of guide members 151, and the guide members 151 are connected to form an outer border to form a closed frame. The border may have a rectangular frame shape to correspond to the shape.

The guide members 151 may be connected and fixed to each other by welding. Accordingly, the guide unit 150 can be easily disposed inside the border frame 100.

The locking member 155 is formed under the guide part 150 and may have a curved end so that the net can be caught.

For example, the locking member 155 may be formed at a location of an intersection point 153, which is a point at which the plurality of guide members 151 intersect. Accordingly, the guide unit 150 may include a plurality of locking members 155.

The elevating unit 170 may include a wire rope 171, a drum 173, and a driving unit 175.

The wire rope 171 is for connecting the guide unit 150 and the elevating unit 170 and adjusting the position of the guide unit 150 using the power of the elevating unit 170.

For example, the elevating unit 170 may be spaced apart at a predetermined interval on the upper surface of the border frame 100 and a plurality may be installed, and each elevating unit 170 has a point symmetry based on the center of the border frame 100 It can be arranged to achieve. Accordingly, each of the wire ropes 171 may be connected to the rim of the guide unit 150 at a predetermined distance apart from each other.

The drum 173 is wound with a wire rope 171 and may be rotatably connected to the driving unit 175. When the drum 173 rotates in one direction, the wire rope 171 is wound along the outer circumferential surface of the drum 173 and the length of the wire rope 171 sinking in the sea water is shortened, and the drum 173 rotates in the other direction. When the wire rope 171 is released from the drum 173, the length of the wire rope 171 sinking in seawater may be lengthened.

The driving unit 175 is for rotating the drum 173 in one direction or the other direction, and the drum 173 is connected to a rotation shaft (not shown) of the driving unit 175 so that the drum 173 can rotate together along the rotation axis. I can.

For example, the drive unit 175 may be equipped with a reducer 176 to adjust the rotational force and rotational speed of the drum 173, or may be a geared motor integrated with a reducer. The driving unit 175 may adjust the length of the wire rope 171 sinking in seawater by rotating the drum 173 in one direction or the other direction.

Meanwhile, a mounting table 179 is connected to an upper portion of the frame 100 so that an elevating unit 170 may be installed on the upper surface of the mounting table 179. In addition, the elevating unit 170 may further include a bracket 177 for assembling and supporting the driving unit 175 and the drum 173.

The elevating unit 170 may receive power for operating the driving unit 175. For example, a power source may be installed on a ship and a platform (not shown) moored at the sea level, and power required for the operation of the driving unit 175 may be provided by connecting a power cable extending from the power source to the driving unit 175. have.

As another example, a battery, a receiver, and a control device are built into the mounting table 179 to remotely control the operation of the driving unit 175 from the ship.

In addition, the elevating and descending operations of the guide unit 150 are accurately performed by the elevating unit 170, so that each driving unit 175 is simultaneously turned on (On) / off (Off), the cage frame 100 is electrically Wiring (not shown) may be provided.

6 and 7, the guide unit 150 is disposed inside the cage rig 130 and can move upward and downward according to the operation of the elevating unit 170.

The guide unit 150 may be connected to the wire rope 171 of the elevating unit 170 to the rim, and may be disposed inside the cage rig 130 in a state in which the wire rope is connected.

At this time, since the plurality of elevating units 170 are disposed at positions that are point symmetrical to each other on the cage frame 100, the guide unit 150 is not greatly displaced, so that it is possible to maintain a horizontal state in seawater.

When the drum 173 rotates in one direction by the driving unit 175, the wire rope 171 wound around the drum 173 is unwound, and at this time, the guide unit 150 can move downward by its own weight. . In this case, the wire rope 171 may be formed to have a sufficient length so that the guide portion 150 can be positioned at the lower end of the cage rig 130.

Accordingly, the guide portion 150 is disposed at the lower end of the street net 130 so that the locking member 155 of the guide portion 150 can be caught in the mesh of the bottom surface of the street net 130.

On the other hand, when the drum is rotated in the other direction by the driving unit 175, the wire rope 171 can be wound around the drum 173 according to the rotation of the drum 173, and the guide unit by the tension of the wire rope 171 (150) can be pulled and moved upwards. At this time, the lower net of the cage rig 130 may be pulled together by the locking member 155.

For example, as the point at which each of the locking members 155 is hung in the street rig 130 is pulled upward, the mesh adjacent to the point where the locking member 155 is hung is also pulled together.

Accordingly, the connection point at which the locking member 155 is hung in the lower net moves upward, and the mesh adjacent to the connection point forms a parabolic line, and the inner space of the cage rig 130 can be partitioned based on the connection point. have.

At this time, since the guide unit 150 is formed in a frame shape, it is possible to prevent each side of the cage rig 130 from getting entangled with each other even when moving in the vertical direction from the inside of the cage rig 130.

In addition, when the guide unit 150 moves upward while the locking member 155 is connected to the lower surface of the cage rig 130, the space inside the cage rig 130 is partitioned, so that during the towing process of the cage farm 1 It is prevented from being pulled to one side according to the resistance of seawater and the movement of the fish group, and damage to the cage 130 and fish can be prevented.
