Description

Submersible fish cage by a central buoyancy control

The present invention by installing a buoyancy change device in the buoyancy center of the upper or lower or upper and lower parts of the frame for the body frame of the water cage, so that the body of the cage is submerged in the water in case of an emergency such as red tide or typhoon to rise to the surface again The present invention relates to a submerged floating cage device by the central force control, which enables the work to be carried out by the central force control method of the cage, thereby enabling the submerged or injured work of the cage body to be carried out very easily, stably and efficiently.

Generally, a water cage is a facility that installs cages to a certain extent in waters such as coastal waters or the open seas, and grows various fishes in the sea with high density. The cage is being moved to deep sea waters.

As the water cage passes freely inside and outside the cage through the mesh of cage leagues, the seawater exchange and oxygen supply are made smoothly, and the wastes generated in the metabolic process of farmed fish are also automatically passed through cage leagues. Because it is discharged from wastewater, there is no need to remove waste products separately, and the high quality of fish farms does not deteriorate the cages, which provides several advantages for large-scale farming.

When natural disasters such as red tide and typhoon occur during the process of operating and operating the above water cages, the water cage facility should be moved to a safe place by using ships, etc. Considering this, there was a problem that it is difficult to apply realistically, and thus, a submerged floating cage device is being used to sink the water cage into the water in case of an emergency such as a red tide or typhoon, and then float it to the surface again.

As above, place the water cage on the surface of the water, and in case of an emergency such as red tide or typhoon, the water cage can be submerged in the water for a certain depth, and after the red tide or typhoon has passed, the water cage will be used again. As a representative example of the submerged floating cage, the floating and submersible breakproof movable cages described in Korean Patent Publication No. 10-2008-88200 (published date: October 20, 2008) can be given.

In the conventional submerged floating cage device, by selectively injecting compressed air or seawater into the buoyancy pipe provided on the upper side of the cage league, so that the water cage is settled or floated by the buoyancy of the seawater weight or air. On the other hand, by connecting the buoyancy pipe to the large ball by the rope of a predetermined length, it was possible to confirm the sinking position of the water cage as a ball.

In the conventional submerged floating cage system, the process of submerging the water cage is performed by opening both the seawater valve and the air valve installed in the buoyancy pipe to allow seawater to flow into the buoyancy pipe, and to raise the water cage again. In the process, the air compressor provided in the vessel is connected to the air valve of the buoyancy pipe by an air hose while the seawater valve of the buoyancy pipe is opened, and the compressed air is stored in the buoyancy pipe as the compressed air is injected into the buoyancy pipe. After the seawater is discharged through the seawater valve, the seawater valve is finally closed.

However, according to the conventional submerged floating cage device, as the seawater flows into one side of the buoyancy pipe while the seawater flows in or out of one side of the buoyancy pipe having a diameter of about 10 m to 30 m, the buoyancy force is increased. The pipe does not maintain the balance in the horizontal direction, due to the eccentricity of the seawater due to the eccentricity, it is easy to swing while tilting in the up and down direction, due to this there was a problem that the settlement or floating work of the water cage is difficult to perform stably.

In particular, if the buoyancy pipe of the upper side of the water cage is inclined in the up and down direction, the deflection phenomenon occurs in the water cage, and since the overlapping or pulling of the water cage, which forms the water cage, occurs, Not only does fish suffer from a lot of stress, but it also causes damage to fish as fish farms tend to flock to one side of the cage, thereby lowering the value of farmed fish and providing factors that cause fish to die in severe cases. There was this.

As a countermeasure for this, the internal space of the buoyancy pipe is partitioned into compartments of a constant interval, and each compartment is introduced into each compartment using an electronic control device with an automatic seawater valve and an air valve installed. Although it is known to control sea water and air at the same time, this increases the overall facility cost of the water cage according to the application of a complicated valve device and a control device, and effectively sinks the water cage by effectively implementing the function of the control device. And injury work also had a problem that is very difficult.

On the other hand, it is known that the cylindrical buoyancy control device is installed along the inner center of the water cage, but the hydraulic resistance applied to the buoyancy control device is very large, which deteriorates the durability and service life of the water cage. The cylindrical buoyancy control device is not only difficult to operate the water cage effectively, but also has a problem that the facility cost and maintenance cost of the water cage are greatly increased, and the cylindrical buoyancy control device is located inside the cage. As a result, there was a problem in that the aquaculture space inside the cage is greatly reduced.

The present invention has been made to solve the above conventional problems, the submerged floating cage according to the central force control according to the present invention, the upper or lower or upper and lower centers of the cage body for water cages, that is, the cage Install a buoyancy controller in the shape of a cylindrical tank that can sink or float the cage body by selectively injecting seawater or air into the buoyancy center of the main body, and the buoyancy controller is provided with a top pipe or bottom pipe for the cage body by a plurality of radial connecting ropes. By being connected to the frame, subsidence or injury of the cage body can be performed very easily and reliably without deflection by controlling the central force, thereby minimizing stress and injury to farmed fish, and reducing water resistance. While keeping durability and service life enough, Facilities that value so as to costs or operating and maintenance costs are significantly reduced and as a technical challenge.

In addition, the present invention by installing an additional buoyancy pipe that is capable of selective injection of seawater or air to the outside of the upper pipe of the cage body, so that the settlement and floating operation of the cage body is performed more stably by the excess buoyancy pipe In the situation where the working condition of the sea is not good due to the high digging, it is possible to perform the sinking operation of the cage body by remote control method in ship or onshore, thus preventing the safety accident and human injury caused by the underwater work. Another technical challenge is to make it easier to carry out the operations of net cages without the movement of fish that are farmed in the cages. Shall be.

The present invention as a means for solving the above technical problem, the buoyancy body to settle or float the confinement body and the confinement body is connected to the frame based on the upper pipe and lower frame of a circular, square or polygonal shape The buoyancy controller comprises a controller, a buoyancy control tank providing an empty space therein, a cover plate assembled at an upper side of the buoyancy control tank, and a weight installed below the buoyancy control tank. And a seawater valve installed through the bottom side of the buoyancy control tank, and an air valve installed through the cover plate, wherein the air valve is connected to a control unit located on the water surface by an air hose. On the upper surface of the control unit, the submerged floating type equipped with air injection and discharge means connected to the air hose In the storage device, the buoyancy controller is disposed on the buoyancy center axis of the cage body, while the upper pipe or the bottom pipe of the cage body is formed by a plurality of radial connecting ropes that are coupled to the cover plate. It is installed connected to the frame, or connected to the upper pipe and the lower frame, respectively.

In addition, an excess buoyancy pipe is located outside the upper pipe and connected integrally with the upper pipe, and one partition is installed inside the excess buoyancy pipe, and an air valve and a seawater valve are disposed between the partition walls. It is installed through the upper side and the lower side of the surplus buoyancy pipe, respectively, characterized in that the air valve of the surplus buoyancy pipe is connected to the control unit by an air hose, the upper pipe and the lower frame by a plurality of tendons It is connected and installed, characterized in that the cage is suspended in the upper pipe and the lower frame by a net fixing line in a state located inside the tendon, the seawater valve and air valve is an automatic solenoid valve, the control unit This includes wireless transmitters and waves measuring sensors that can exchange signals with ships or onshore. , By the received control signal and the water valve and the control units are provided respectively for operating the air valve, the water valve and the air valve is characterized in that the installation control unit controls the buoy and connection by a cable.

According to the present invention as described above, as the buoyancy controller as a cylindrical tank is located at the center of gravity of the entire system constituting the cage main body, it does not affect the geometric balance change but only a scalar change called the sedimentation force of the cage main body. By inducing, it is possible to maintain a stable balance of the cage body and thereby to operate a stable settlement.

As described above, it is possible to operate a highly stable sinking body without deflection of the cage body, so that overlapping or deflection of cage cages constituting the cage body does not occur, thereby minimizing stress received by farmed fish during settlement of cage body. Not only is it effective, it also has the effect of preventing fish damage caused by fish farming on one side of the cage, thereby preventing the death of farmed fish and greatly improving the product value of farmed fish. There is.

In particular, due to the simple installation structure of buoyancy controller, easy operation method, easy grafting with water mooring circular cage, and convenience of repair or replacement, it is possible to effectively operate the cage facility. There is an effect of providing a submerged flotation cage which is very economical, functional and effective to perform sinking and floating operation very easily and easily while greatly reducing the overall facility cost and maintenance cost.

In addition, since a large buoyancy control device is not located inside the cage, and a small buoyancy controller in the shape of a cylindrical tank is located on the outside of the cage, the hydraulic resistance applied to the buoyancy controller is minimized to ensure durability of the cage body. In addition, it is effective in securing the service life of the cage, so that the operation of the cage system is hardly restricted by the buoyancy controller, and also secures the farming space inside the cage so as to improve the productivity of the fish.

On the other hand, in situations where the working conditions of the sea are not good, such as high digging, the sinking operation of the cage body can be performed remotely on ships or on land, thereby preventing the safety accidents and injury of workers. In addition, it is possible to perform net fishing of caged nets without the movement of fish farmed in aquatic cages, which makes it possible to operate the caged facilities more economically and efficiently.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Submerged floating cage device 1 according to the present invention, as shown in Figures 1 and 2, respectively, a cage body as a water cage containing a cage, and the cage body 10 is the water surface 8 As a means for supporting the state of being injured by the anchor), the anchoring (2) and the buoy (3) and the rope (4) (5) (6) (7) and the linking body (10) sinking and floating operation It includes a buoyancy controller 12 to perform, and a control unit 13 for the operation of the buoyancy controller 12.

The anchor 2 may be a conventional anchor or a metal pile, or may be a heavy concrete block, and the buoy 3 and the control unit 13 are usually made of a styrofoam or plastic material. Although it is common to manufacture in a shape or a cylindrical shape, it is a matter of course that various other materials which have moderate buoyancy and strength (wave resistance) are applicable.

The support means of the cage body (10), four anchors (2) fixed to the sea bottom in the outer direction of the cage body 10, and extends in the vertical direction from the anchor (2) buoys on the top Four support ropes (3) (3) are provided, and four outer ropes (5) connected in the horizontal direction to the upper side of the support ropes (6) and installed in the form surrounding the outer side of the cage body (5) (5). Based).

The cage body (10) is installed to be supported by four cage ropes (7) which are bound at each connection portion of the support rope (6) and the outer rope (5), while each cage rope (7) is a cage body By being connected to the upper pipe 11 of (10), as shown in (a) and (b) of Figure 2, each of the cage rope (7) of the cage body 10 by the buoyancy controller 12 It is a means for substantially supporting the floating and subsided state.

In addition, in order to further improve the facility strength of the cage device (1), a total of eight anchor ropes (4) for each of the connecting portion of the support rope (6) and the outer rope (5), respectively, downward Anchor 2 extending inclined and fixed to the bottom of each anchor rope 4 is installed, the anchor 2 may also be a conventional anchor or a metal pile, or may be a heavy concrete block. have.

The overall structure of the cage device 1 shown on the basis of Figs. 1 and 2 is just one representative embodiment, which stably installs the cage body 10 as a water cage on the water surface 8 while buoyancy. If it can support the settlement and floating operation of the cage body 10 by the controller 12, the cage using the anchor 2, the buoy 3, and the ropes 4, 5, 6 and 7 The installation structure of the main body 10 is to be understood that various structures other than the form shown in the drawings can be applied.

As shown more clearly in FIG. 3, the cage body 10 has a bag-shaped cage league based on the top pipe 11 and the bottom frame 15 of a round, square or polygonal loop shape. 10a) is formed in a connection configuration, the net reinforcement tendon is installed at a predetermined interval along the periphery of the cage 10a bar, which is a widely applied to ordinary water cages.

The upper pipe 11 is made of a plastic or synthetic resin such as high density polyethylene (HDPE) to be a buoyancy pipe in its empty state, and the lower frame 15 has the same shape as the upper pipe (11) However, it is preferable to use a corrosion-resistant metal frame such as stainless steel (SUS) which provides a predetermined settling force.

If necessary, one or two frame frames may be additionally installed between the upper pipe 11 and the lower frame 15 to more stably maintain the appearance of the cage 10a. In the state in which the lower frame 15 is not made of a metal frame but installed in a plastic frame, a needle is installed at the bottom of the lower frame 15 or the cage 10a, and the cage 10a. You can also let it hang down.

In addition, the upper cover of the cage 10a is not shown cover net is installed so that the submerged cultured fish of the cage main body 10 to the outside of course, the cover web is usually the inner peripheral surface of the upper pipe (11) On the other hand, it is generally installed to separate the cover net from the upper pipe (11) for the feeding and shipping of feed fish or the supply of feed.

The buoyancy controller 12 used to settle or float the cage body 10 as a constituent element of the first aspect of the present invention, as shown in Figure 3, the upper or lower or upper portion of the cage body (10) While located in the lower center, it is connected to the upper pipe 11 and / or the lower frame 15 of the cage body 10 by a plurality of radial connecting rope (17).

If only one buoyancy controller 12 is installed, the lower center side of the cage body 10 is more preferable than the upper center side of the cage body 10, and if two buoyancy controllers 12 are installed as shown in the drawing, Although the upper and lower centers of the cage body 10 are provided, one buoyancy controller 12 may be provided at the upper center side of the cage body 10, and the buoyancy controller 12 may have a cylindrical tank shape. Of course, the rectangular tank shape may be preferred.

As shown in (a) and (b) of FIG. 4, the buoyancy controller 12 has a buoyancy control tank 20 providing an empty space therein and an upper side of the buoyancy control tank 20. The cover plate 21 is assembled and coupled to the connecting rope 17, the weight 22 is installed below the buoyancy control tank 20, and installed through the bottom side of the buoyancy control tank 20. It consists of a seawater valve 18 and an air valve 19 installed through the cover plate 21.

Preferably, the buoyancy control tank 20 and the cover plate 21 are made of a corrosion-resistant metal material or a plastic material, and as shown in the drawing, an upper flange portion of the buoyancy control tank 20 using the assembling bolt 25. In the case of installing the cover plate 21 in a prefabricated manner, it is preferable to interpose a hermetic sealing ring between the upper surface of the buoyancy control tank 20 and the lower surface of the cover plate 21, and the buoyancy control tank 20 ) And the cover plate 21 can be assembled by adhesive or screwing.

In addition, a total of 12 connection ropes 17 are used in the drawing so that the buoyancy controller 12 can be suspended from the center side of the cage body 10 to the upper pipe 11 and / or the lower frame 15. Although shown, the number of connecting ropes 17 can be arbitrarily increased or decreased in consideration of the supporting force of the buoyancy controller 12, and each connecting rope 17 has a binding hole formed at the outer periphery of the cover plate 21 ( Although shown as bound to 24, instead of the binding hole 24, a binding ring or the like may be provided along the outer periphery of the cover plate 21.

In addition, in the case of the weight (22), it is most preferably inserted into the weight case 23 provided on the lower side of the buoyancy control tank 20, the weight (22) buoyancy control tank 20 It is also possible to be attached to the lower side of the installation or hanging, weight 22 is usually used lead, but due to the environmental pollution problem the use of lead is limited because other metal blocks or concrete blocks can be used. .

The most important point in the application of the weight (22) as described above is that when the cage is placed on the surface, the buoyancy of the entire cage should be "neutral buoyancy + α", the buoyancy of α is the cage body (10) ) Is a positive buoyancy that floats to the surface 8, which is a sedimentation force generated from the buoyancy controller 12 by the weight of the weight (22) and the sea water when the seawater is filled into the buoyancy controller (12) Must be smaller than the negative buoyancy).

In addition, so that the buoyancy controller 12 can support the cage body 10 more stably, even though the seawater is not filled into the buoyancy controller 12, the buoyancy controller 12 by the weight of the weight (22) ) Itself has a predetermined sound buoyancy, that is, the larger the settling force provided by the weight (22) than the buoyancy provided by the empty space inside the buoyancy control tank 20, buoyancy controller 12 The negative buoyancy of itself should be less than the positive buoyancy of α.

If the buoyancy value of α is greater than or equal to the sedimentation generated by the buoyancy controller 12 by the seawater and the weight weight 22, the buoyancy controller 12 is included even if seawater is filled into the buoyancy controller 12. The total buoyancy of the cage body (10) is "neutral buoyancy + positive buoyancy" or "neutral buoyancy + 0" to continue to float on the surface (8), the seawater is not filled in the buoyancy controller 12 If the non-invasive state is larger than the buoyancy value of α, the cage body 10 is always in the state of being submerged in water, and in consideration of this buoyancy relationship, the weight of the weight 22 should be appropriately adjusted.

And, as another component constituting the buoyancy controller 12, the seawater valve 18 is installed through the bottom surface of one side (right in the drawing) of the buoyancy control tank 20, the air valve 19 is As it is installed through the center of the cover plate 21, as shown in the figure, the installation of the seawater valve 18 at the bottom and the air valve 19 at the top, the natural inflow of seawater and compressed air It is preferable in terms of effective discharge of seawater.

As long as the seawater valve 18 and the air valve 19 are valves that can be used in seawater without fear of corrosion, any type of seawater valves may be used, but in the case of manual type, seawater ball valves are most preferable, in this case, seawater valves 18 and the air valve 19 are provided with known valve handles for manual opening and closing operations, respectively, and the air valve 19 of the buoyancy controller 12 is provided on the water surface 8 by the air hose 14. It is installed in connection with the control unit 13 is located.

The air injection and discharge means communicating with the buoyancy control tank 20 by the air hose 14 is provided on the upper surface of the control unit 13, the air injection and discharge means penetrates the control unit 13 The air hose 14 itself protrudes to the upper side, and as shown in Figure 7 for the convenience of the air injection and discharge operation hose pipe 27 made of metal or plastic material and the air hose 14 It is also possible to install it in the control part 13.

As described above, an end portion of the air hose 14 or the hose pipe 27 protruding to the upper side of the control unit 13 is connected to a pneumatic line extending from a ship air compressor or a high pressure oxygen tank. It is desirable to provide a pipe connector in the shape of a plug or a plug, and it is desirable to provide a separate plug to prevent the inflow of seawater.

As the components corresponding to the second main part of the present invention, as shown in Figs. 3 and 5, respectively, in the state where the surplus buoyancy pipe 16 is located outside the upper end pipe 11 of the cage body 10, The excess buoyancy pipe 16 is to be installed integrally with the upper pipe 11, and the excess buoyancy pipe 16 also uses a plastic or synthetic resin such as high density polyethylene (HDPE) like the upper pipe (11) The buoyancy pipe inside is empty.

Although a total of two redundant buoyancy pipes 16 are shown in the drawing, the number of installations of the redundant buoyancy pipes 16 may be at least one to three, and as shown in FIG. 6 more clearly, One partition 26 is installed inside the excess buoyancy pipe 16, while an air valve 19 and a seawater valve 18 are disposed on the partition 26 with an upper portion of the excess buoyancy pipe 16. It is installed through the side and the lower side respectively.

When the air valve 19 and the seawater valve 18 are installed on the upper side and the lower side, respectively, with the partition 26 therebetween, the seawater coming in from the lower side exits again through the upper air valve 19. Alternatively, the seawater can prevent the air discharge from being delayed by blocking the air valve 19. In the process of injecting air into the air valve 19, the air coming from the upper portion of the seawater is directly below the partition wall 26. It is possible to discharge the seawater in the surplus buoyancy pipe 16 without exiting through the valve 18, whereby the compressed air injected into the air valve 19 unnecessarily escapes through the seawater valve 18 It can prevent.

The air valve 19 and the seawater valve 18 for the surplus buoyancy pipe 16 also have the same technical configuration as that installed in the buoyancy controller 12, and the air valve 19 of the surplus buoyancy pipe 16 is likewise air. It is connected to the air injection and discharge means provided on the upper surface of the control unit 13 by the hose (14).

Therefore, only when both the buoyancy controller 12 and the excess buoyancy pipe 16 is applied, the air injection and discharge connected to the air hose 14 for the buoyancy controller 12 on the upper surface of the control unit 13 The means and the air injection and discharge means connected to the air hose 14 for the excess buoyancy pipe 16 should be provided separately, but the buoyancy controller 12 and the excess buoyancy pipe using one air injection and discharge means. Of course, it is also possible to simultaneously perform the air injection and discharge operations through (16).

The excess buoyancy pipe (16) is usually in the air flows to provide a sufficient buoyancy necessary for the rise of the cage body (10) together with the upper pipe (11), while the sedimentation of the cage body (10) inflow of seawater By canceling the buoyancy provided to the upper pipe (11), it is responsible for the function to more precisely control the settlement work of the cage body (10) by the buoyancy controller (12).

Of course, fluctuations of the surplus buoyancy pipe 16 may occur in the process of injecting or discharging seawater through the surplus buoyancy pipe 16, but the surplus buoyancy pipe 16 is connected to the upper pipe 11 and the upper pipe 11 Since it is supported by the buoyancy of the), the fluctuation width can be minimized as compared to the conventional case to inject or discharge the seawater to the upper pipe (11) itself.

Hereinafter, the working relationship of the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

First, as shown in (a) of FIG. 2, the cage body 10 is used in a state of floating on the water surface 8, and in case of an emergency in which natural disasters such as red tide and typhoon occur, the ship S is After moving to the sea area where the cage device 1 is installed, the worker enters the water and performs the settlement of the cage body 10.

In the settlement process of the cage body 10 as described above, the seawater valve 18 and the air valve 19 installed in the surplus buoyancy pipe 16 are primarily opened, so that the seawater valve 18 of the surplus buoyancy pipe 16 is opened. The natural water is introduced through the air) while the internal air of the excess buoyancy pipe 16 is automatically discharged through the air valve 19 and the air hose 14.

After the seawater is filled in the excess buoyancy pipe 16 through the above process, the seawater valve 18 is opened by opening the seawater valve 18 and the air valve 19 of the buoyancy controller 12. Sea water is introduced into the lower portion of the buoyancy control tank 20 while the internal air of the buoyancy control tank 20 is discharged upward through the air valve 19 and the air hose 14.

By going through the same process as described above, from the time when the sedimentation (sea water + weight weight) generated from the buoyancy controller 12 exceeds the positive buoyancy (α) of the cage body (10), the cage body (10) gradually sinks, Finally, the settlement of the cage body 10 is completed in the state as shown in FIG.

As described above, after the cage body 10 is submerged in water during an emergency such as a red tide or a typhoon, and after the red tide or the typhoon is completely extinguished, the cage (1) moves to the sea area where the cage device 1 is installed. Next, the worker enters the body of water to perform the injury operation of the cage body (10).

The floating process of the cage body 10 as described above, by connecting the air injection and discharge means installed in the control unit 13 with the air compressor or high-pressure oxygen tank for the ship (S), air hose 14 and buoyancy controller ( When compressed air is injected through the air valve 19 of 12), the seawater stored in the buoyancy control tank 20 is discharged through the seawater valve 18 at the bottom and the inside of the buoyancy control tank 20 It is filled with air.

Due to this, buoyancy as much as seawater is generated in the buoyancy controller 12 is generated, while the entire cage body 10 is converted to positive buoyancy, so that the cage body 10 gradually rises, and the buoyancy control tank 20 As soon as air is completely filled in the air bubbles in the seawater valve 18, the air valve 19 and the seawater valve 18 are sequentially closed.

As described above, when the air valve 19 is first closed while the air is completely filled in the buoyancy control tank 20, the seawater is no longer introduced due to the pressure of the air filled in the buoyancy control tank 20. Therefore, the seawater valve 18 may be closed after the floating operation of the cage body 10 is completed.

After the injection operation of air through the buoyancy controller 12 as described above or at the same time, by injecting compressed air through the air valve 19 of the excess buoyancy pipe 16, as shown in (b) of FIG. From the subsided state to restore the cage body 10 to the injured state shown in Figure 2 (a), as soon as the air is completely filled with air in the surplus buoyancy pipe 16 is discharged to the seawater valve (18) The air valve 19 and the seawater valve 18 of the excess buoyancy pipe 16 are sequentially closed.

In the manner as described above can be performed whenever necessary to settle and injure the cage body (10), the actual subsidence and floating process of the cage body (10) buoyancy controller (located in the center of the cage body (10) ( 12), a very stable sinking and floating operation is possible without deflection of the cage body (10).

In other words, as the seawater is directly introduced and discharged through the upper pipe 11 for the cage body 10, the upper pipe 11 does not maintain the balance in the horizontal direction, and due to the eccentricity due to the weight of the seawater, While completely overcoming the conventional problems that were rocking while tilting downward, it is possible to effectively settle and float using the buoyancy controller 12 located in the center of the cage body 10.

More precisely, the buoyancy controller 12 as a cylindrical tank installed on the upper, lower or upper and lower centers of the cage body 10 is located at the center of gravity of the entire system forming the cage body 10, thereby providing a geometric balance. By inducing only a scalar change called the sedimentation force of the cage body 10 without affecting the change, it means that the balance body of the cage body 10 and stable settlement operation through it are possible.

As described above, since a very stable settlement and floating operation are possible without deflection of the cage body 10, since the overlapping or pulling phenomenon of the cage league 10a constituting the cage body 10 does not occur, the cage body 10 is In addition to minimizing the stress of farmed fish during sinking or injured work, it is also possible to prevent damage to the fish caused by farmed fish being driven to one side of the cage (10a). It is possible to prevent the death of fish and to greatly increase the value of fish farmed.

In particular, a simple structure in which the buoyancy controller 12 having a cylindrical tank shape is suspended from the upper pipe 11 or the lower frame 15 and installed in the seawater or air selectively through the buoyancy controller 12 to provide a cage body. The stable sinking and floating operation of (10) is possible, and the buoyancy controller 12 can be easily grafted to the existing water mooring circular cage, and the buoyancy controller 12 is very easy to repair or replace. In this way, effective operation of cage facilities is also possible.

For this reason, when the upper pipe 11 is divided into a plurality of compartments, and then a valve device is installed in each compartment, the entire facility of the cage device 1 is compared with the conventional cage device, which is operated by a complicated control device. Since the sinking and floating operation can be performed very easily and easily while greatly reducing the cost or maintenance cost, it is possible to provide a sinking type cage device (1) which is very economical, functional and effective.

On the other hand, in the submerged floating cage device 1 of the present invention, a large buoyancy control device is not located inside the cage league 10a, and a small buoyancy in the shape of a cylindrical tank on the outside of the cage league 10a. As the controller 12 is located, the hydraulic resistance applied to the buoyancy controller 12 can be minimized to ensure sufficient durability or service life of the cage body 10, and the facility operation of the cage device 1 is a buoyancy controller. (12) can be hardly restricted, and can also contribute to the aspect of improving the productivity of farmed fish by securing enough aquaculture space inside the cage (10a).

As the components corresponding to the third main part of the present invention, as shown in Figs. 4, 6 and 7, respectively, the seawater valve 18 and the air valve 19 are automatic solenoid valves. 13, a radio transmitter 29 having an antenna 13a, a wave height measuring sensor 35, and a ship S or land (L) to exchange signals with the ship S or land (L). The control unit 30 for operating the seawater valve 18 and the air valve 19 in accordance with the control signal received from each is installed, the seawater valve 18 and the air valve 19 is controlled by a cable 14a The connection to the control unit 30 of the buoy 13 is to be installed.

The repeater 31 transmits the data measured from the wave height measuring sensor 35 to the radio transceiver 29 and transmits the data to the ship S or the land L. While remotely determining the height and the possibility of field work, and performs the function of inputting the control signal transmitted from the ship (S) or land (L) via the radio transceiver 29 to the controller 33, the controller 33 performs a function of processing the control signal input through the repeater 31 to operate the seawater valve 18 and the air valve 19 in an ON / OFF manner whenever necessary by the power of the battery 32. .

Therefore, in a situation where the height of the wave measured from the wave height measuring sensor 35 exceeds a threshold value, i.e., the situation of field work at sea is very poor, the remote control method is used in the ship S or the land L. Settlement operation of the cage body (10) by doing so, it is possible to prevent the accident and safety of workers due to dangerous underwater work in advance, the settlement operation of the cage body (10) by a remote control method Again, this is done in the same order as the field work described above.

On the other hand, the floating operation of the cage body (10) is to be carried out directly in the field by selecting a good weather conditions, the operation of the seawater valve 18 and the air valve 19 on the upper surface of the control unit 13 for this purpose The manual control unit 36 is provided for the bar, and the manual control unit 36 is provided with an ON / OFF switch or a button to perform an operation of the valve in connection with the controller 33, and the battery during the field work Filling hole (32a) is provided on the upper surface of the control unit 13 to enable the charging of the 32, the operation to injure the cage body 10 is also made in the same manner as described above.

The configuration of the control unit 13 shown in FIG. 7 is just one representative embodiment that can be applied to the present invention. In addition to the remote control of various other methods, the manual control unit 36 and While installing the airtight cover to block the inflow of sea water to the filling port (32a), the weight (22) for the stable mooring of the control unit 13 in the lower portion of the buoyancy cylinder 28 constituting the control unit 13 It is desirable to install.

Even in the automation of the remote control method as described above, it is possible to provide a simple and effective settling injury control device than the case in which a large number of valve devices are proportionally controlled using a complex control device as in the conventional case, thereby controlling Not only is there a much less chance of a device failure or malfunction, but also the maintenance costs to repair or replace a control device in the event of damage or failure of the control device can be significantly reduced.

Finally, as shown in FIG. 3 as a component corresponding to the fourth main part of the present invention, the upper pipe 11 and the lower frame 15 are connected to each other by a plurality of tendons 10c. The upper pipe 11 and the lower frame 15 are positioned at the inside of the tendon 10c at the same time, and the upper and lower sides of the cage 10a are fixed by a net fixing line 10b. It is installed to hang on, and if necessary, the central side of the cage 10a may be connected to each tendon 10c by a net fixing line 10b.

As described above, when the cage 10a is dually installed with the upper pipe 11 and the lower frame 15, the cage frame 10a and the buoyancy controller 12 are caged during the meshing operation of the cage 10a. It is possible to easily replace only the cage (10a) without the need to lift with the net (10a), as well as the netting operation is possible without moving the fish farmed in the cage (10a).

In other words, after a certain period of time after the installation of the cage league 10a, a variety of organisms are attached to the surface of the net and the mesh is blocked, which may threaten the health of the farmed organisms because the distribution of seawater is not made smoothly. In addition, since the breakage and deformation of the cage (10a) is caused by the resistance due to the increase in the net area, the net must be periodically changed during the operation of the water cage.

However, the sinking floating water cages developed to date are mostly installed without considering such netting, so it is not only expensive and time wasted when netting, but also can not be performed directly by the on-site management personnel. Because it often requires specialized facilities and methods of the bar, even when reluctant to use in the field occurs at all, according to the installation structure of the cage league (10a) corresponding to the fourth aspect of the present invention to completely solve these problems can do.

As a process of netting according to the present invention, as shown in (a) of FIG. 8, a new net (cylindrical net having an upper and lower opening) to be replaced on top of the existing net, and then the lower end of the new net It is connected to the upper end of the net. At this time, if there is a cover net in the existing net, the operation is performed with the cover net removed.

After completing the operation as described above, while tying the upper end of the new net to the upper pipe 11 of the cage body 10, while separating the upper end of the existing net from the upper pipe 11, then the As in) and (C), the new net is stretched downwards, while the existing net is folded downwards and folded.

In the above state, the bottom net of the existing net connected to the lower frame 15 of the cage body 10 is first separated from the lower frame 15, and then the lower end of the new net while cutting the trunk of the existing net When it is connected to the bottom net of the existing net, it is possible to easily and economically net, that is, the net of the trunk without the movement of the cultured creatures in the interior of the cage (10a), which allows efficient operation of the water cage facility It can provide many benefits to the side.
