Description

Nursing System for Raising Fishes Having Buoyancy-Control Function and Balance-Floating Function and Method of Using the System}

Field of invention

The present invention relates to cage farms. More specifically, the present invention relates to a cage farm structure that can float on the sea surface or submerge into the sea by injecting air into the inside of the farm frame or by releasing the air. The present invention also relates to a method of allowing cages to float on the sea surface or to submerge into the sea. The present invention relates to a cage farm that can be installed on the coast as well as offshore by allowing the cage to float on the surface of the sea or to dive into the sea. The present invention relates to a cage farm that can float on the sea surface and submerge into the sea while keeping the cage farm structure horizontal without being tilted when the cage farm structure is floated or submerged on the sea surface.

Background of the Invention

Cultivated farms for aquaculture are widely used around the coast of the sea adjacent to the land. Because offshore areas are deep and deep, the cages have been actively used in coastal areas where the waves are not severe and deep.

The conventional cage farm fishing net structure is installed so that the cage is floating above the sea surface, the fishing net is located in the sea inside the frame. Fishing nets are secured to the cage by means of strings at the top. The bottom of the fishing net is extended to secure the anchor. The inside of the fishing net is the activity space of the fish to be farmed, and the fish grows in this space. The cage is fixed to the bottom of the buoyant material as necessary to float on the sea by buoyancy. The cage is a floating quadrilateral shape, about 60cm ~ 1m wide, where people walk over it to feed into fishnets or do other necessary work.

So far, the cage has been made to form a certain shape like a quadrilateral by combining wood (wood) and iron pipes with fastening means such as nails, and fixing the rich man made of Schiropol to the bottom of the frame so that the cage is floating on the surface of the water. Let's do it. The upper part of the cage is a structure that people can walk along the periphery of the frame, while walking on the frame to feed or take care of the fish and shellfish that are farmed inside the fishery. However, since the conventional cage is made of wood and iron pipes, the wood is broken in the severe waves, and the broken woods rot to pollute the coast. In addition, the traditional cages are supported by dragging the rich made of Schiropol to the lower portion of the cage, and as time passes Schiropol can be crushed to maintain proper buoyancy, the crushed Schiropol is scattered on the sea surface causing a lot of environmental pollution have. Due to the above problems, Schiropol rich man usually has to replace about once a year, wood should be replaced about once every 2-3 years. In particular, when a typhoon occurs, the cage is frequently broken. Therefore, the conventional caged float floating on the surface of the water can be installed around the coast with relatively little typhoon damage.

Conventional cage farm net structure has a length of about 5 to 15 m on one side of a quadrangular structure, and the depth of the fishing net is usually about 3 to 4 m. In some cases, fishing net structures with a depth of about 10 m are used.

Conventional fishing net structure is mainly installed on the coast, the fishing net maintains the unfolded state by the gravity of the fixed weight installed in the sea. Conventional fishing net structures cannot be installed in the offshore area where the water depth is 20 to 30 m beyond 10 m. If a short-length fishing net structure is installed in a place where the waves are severe, the fishing net will be inverted, causing all the farmed fish to flow out into the sea. In addition, fishing net structures with long lengths of fish nets are entangled with each other when the waves are severe, and as a result, farmed fish die.

In the conventional fishing net structure, the depth of the fishing net is changed due to the large change in the water depth in the west coast region where the tidal current is severe or the tidal difference is large, and the fishing net is twisted or flipped. Therefore, the conventional fishing net structure has been used mainly installed in the shallow coastal area.

Cage farms in coastal areas also cause other problems. In cage farming, the large amount of feed used to feed the farmed fish causes pollution in coastal areas. On the other hand, coastal seawater is contaminated by land contaminated rivers and factory wastewater, resulting in contaminated farmed fish. Because of these problems, many studies and attempts have been made to establish caged farms in the offshore area.

In addition, the conventional caged fish farming structure is installed in a shallow coastal area, and when a red tide occurs, the fish do not have a space to avoid the red tide layer, so that almost all fish are dead.

The present inventors can solve the above-mentioned limitations of the cage farm, and develop a cage farm net structure of the present invention that can be installed without any problem in coastal areas as well as offshore areas patent application No. 98-28383 (1998. 7. 14 applications) and 98-31310 (filed July 31, 1998). The present inventor has developed a cage farm structure that can be installed without any problem in the offshore areas where waves are severely hit by having the ability to dive into the sea, and the patent application No. 98-37930 (filed Sep. 15, 1998) Patent No. 98-31310 (filed on July 31, 1998), which was further improved to file a cage farm structure with a smooth diving function as patent application No. 99-23727 (filed on June 23, 1999). It was.

The invention of patent application 99-23727 is a nearly complete form of cage farm structure with a diving function. However, when the cages are submerged or floated to the surface of the sea, the structure is tilted to one side. In the case of submerging or floating the structure, water and air are exchanged inside the frame, so when water is biased to one side of the frame due to the difference in specific gravity, the structure is inclined. If the structure is tilted to one side, the fishing net installed underneath it also tilts, so the fish inside the fishing net may be severely damaged or die.

Therefore, the present inventors have made a dive or submerged structure while maintaining the substantially horizontal state without tilting to either side when the submerged structure or the submerged structure is floated to the sea surface to compensate for the shortcomings of the invention of Patent Application No. 99-23727. To develop the cage cage structure of the present invention that can rise.

An object of the present invention is to provide a cage farm structure having a diving control function to be able to float on the surface of the sea or to dive to a certain depth in the sea.

Another object of the present invention is to provide a cage farm structure that can be safely installed in coastal areas as well as offshore areas having a depth of 30 ~ 40m by having a diving control function.

Another object of the present invention is to provide a cage farm structure that can prevent the death of fish even if the red tide phenomenon occurs on the surface of the sea or the surface layer of a certain depth by installing in the deep water area.

Another object of the present invention is to provide a cage farm structure that can be installed in the offshore to prevent seawater pollution in the coastal area and to farm clean fish.

Still another object of the present invention is to provide a cage farm structure that can protect fish from various diseases by installing in a deep water area and further reduce the cost of treatment, thereby reducing the cost of farming.

Another object of the present invention is to provide a conventional rich rich cage farm structure to float the cage on the sea surface by adjusting the buoyancy of the air by injecting air or draining air and injecting seawater into the frame tube of the cage It is to provide.

Still another object of the present invention is to provide a cage structure that is semi-permanent and can be recycled by manufacturing the frame tube of the cage with a synthetic resin such as polyethylene.

Still another object of the present invention is to provide a cage farm structure that can eliminate environmental pollution of the sea by not using conventional wood and Schiropol rich.

It is still another object of the present invention to provide a cage farm structure that can be submerged or floated while maintaining a substantially horizontal state without tilting to either side when submerging the cage farm structure or floating the submerged structure onto the sea surface. It is to.

The above and other objects of the present invention can be achieved by the present invention described below.

Summary of the Invention

The cage farm structure of the present invention forms an outer portion of the structure and has a water outlet at the bottom to have a diving and floating function, and an air valve is formed on the upper side and is provided in a plurality of inner frames of the outer frame made of a synthetic resin pipe. A frame composed of an inner frame 3 formed of a synthetic resin pipe with an air valve formed at an upper portion thereof so that a fishing net is assembled at a lower portion thereof and has a water inlet and a lower portion to have a diving and floating function; A plurality of balance riches (4) fixed to the outer frame and having a water outlet at the top thereof so that the structure can be submerged or floated in a horizontal state; A plurality of fishing nets (17) assembled to the respective inner frames and provided with a load frame having a sufficient load to submerge the structure into the sea; Fixing means consisting of a plurality of rich (14, 15) and the anchor (16) for supporting the structure; And a control system 7 for injecting air into the frame and the balance rich and automatically opening an air valve to discharge the air of the frame and the balance rich and to inject water.

The cage farm structure of the present invention farms fish in a state in which air is injected into the frame tube so that the cage is floating on the sea surface. At this time, if the storm is so severe that you want to submerge the cage structure into the sea, the control system measures the wind speed and when the wind speed reaches a certain speed, the air valves of the frames 2 and 3 open automatically. When the air valve of the frame is opened, the air inside the frame pipe is discharged to the outside. At this time, the seawater is injected into the frame tube through the water entrance. When seawater is injected, cage cage structures submerge into the sea under the load of the lower frame. At this time, since a plurality of balancing riches 4 are provided on the upper portions of the frames 2 and 3, the structure is prevented from tilting to either side due to the buoyancy of the balancing riches. When the frames 2 and 3 submerge into the water and the balance rich floats on the surface of the sea, the air valve of the balanced rich opens automatically. When the air valve of the balanced rich is opened, the air inside the balanced rich is discharged to the outside, and the sea water is injected into the balanced rich through the water outlet of the lower part. The frames 2 and 3 and the balance rich man 4 dive while keeping the level substantially.

At this time, the cage farm structure is submerged by the length of the rope 18 because it is connected to the rich (14) by the rope (18). When the sea is calm after the storm passes, a person takes a boat to approach the control system 7 to close the balance valve and the air valves of the frames 2 and 3 and to operate the compressor to inject air into the balance cylinder. When the balance rich man 4 rises first, air is then injected into the frames 2 and 3. Since the air is filled in the frames 2 and 3, the frames 2 and 3 float on the sea surface. Since the balance richer rises before the frames 2 and 3, the frame rises, so that the structure does not tilt to either side during the injury.

Figure 6 is a schematic diagram for understanding the principle that the water and air is injected and discharged to the frame and the balance rich of the present invention.

As can be seen in Figures 1 and 6, the frame, that is, the frame is composed of a rectangular outer frame (2) forming the outer portion of the structure and a plurality of inner frame (3) assembled inside the outer frame. In FIG. 1, ten inner frames are all installed inside the outer frame, and ten fisheries are formed. Of course, the size of the outer frame and the size and quantity of the inner frame can be changed according to the fishery environment. The frame is a cylindrical tube made of synthetic resin, and a frame made of polyethylene is most preferred. The frame preferably has a diameter in the range of 200 to 800 mm, more preferably in the range of 300 to 500 mm. As shown in FIG. 6, a plurality of connection members 30 are inserted between the outer frame 2 and the inner frame 3 and assembled at predetermined intervals by the fastening band 31. 8 is a schematic perspective view of a connecting member used therebetween for assembling an inner frame and an outer frame;

Figure 2 is a schematic perspective view of the caged farm structure of the present invention floating on the surface of the sea in water, Figure 3 is a schematic perspective view of the structure submerged in the sea underwater. 4 is a schematic front view showing the principle of the structure of the present invention floating on the sea surface, Figure 5 is a schematic front view showing the principle of the structure submerged into the sea.

The cage farm structure 1 is supported by fixing means composed of a plurality of rich people 14 and 15 and the anchor 16 as a whole. The anchor 16 is fixed to the bottom of the sea where the structure 1 is installed, is connected to the rich 15 by a rope, the rich 15 is again connected to the rich 14 by a rope. The rich 14,15 are all floating in the water. The structures 1 are each connected to the rich 14 by rope 18. In Figure 2, the rope 18 is shown taut but need not be kept taut. Because, as shown in Figure 3, the length of the rope 18 adjusts the length of the structure (1) diving. Therefore, as shown in Fig. 4, the rope 18 may be in a loose state.

When the structure 1 of the present invention is submerged or floated, the principle of diving or floating while not being inclined to one side is almost described with reference to FIG.

As shown in FIG. 6, the outer frame 2 and the inner frame 3 are assembled by fastening means such as a connecting member 30 and a fastening band 31, and are provided with a plurality of balances so as to be located on the upper side of the outer frame. The rich man 4 is installed. In the embodiment of FIG. 1, all 10 balanced rich persons are installed, but are not necessarily limited thereto, and may have a buoyancy such that the structure does not tilt when the structure is submerged or floated. This can be easily carried out by those skilled in the art.

The principle of diving or floating while the structure 1 is horizontal is as follows. First, air is injected into the frames 2 and 3 to form fish while the structure 1 is floating on the sea surface. At this time, if the structure 1 is to be submerged, open the air valve 11a (not shown) of the air frame 11a installed in the upper part of the frame 2, 3 and into the frame. Water inlet is injected through the water outlet).

Frames 2 and 3 infused with water are slowly submerged. At this time, the structure is not inclined to either side due to the plurality of balance rich parts 4 installed on the upper part of the structure 1. When the structure 1 submerges into the water and the balance rich man 4 floats on the sea surface, the air valve 11b of the balance rich man is automatically opened by the control system 7. When the air valve of the balance rich part is opened, the air inside the balance rich part is discharged to the outside, and the sea water is injected into the balance rich part through the water outlet 13b of the lower part. The frames 2 and 3 and the balance rich man 4 dive while keeping almost horizontal. At this time, the structure 1 is submerged by the length of the rope 18 because it is connected to the rich (14) by the rope (18). In order to float the submerged structure (1) to the surface of the sea, a person aboard the ship approaches the control system (7), closes both the balance rich and the automatic valve installed on the frame, and operates the compressor (8) to balance the rich rich (4). Inject air inside.

When the balance rich man 4 rises first, air is then injected into the frames 2 and 3. Since the air is filled in the frames 2 and 3, the frames 2 and 3 float on the sea surface. Since the balance richer rises before the frames 2 and 3, the frame rises, so that the structure does not tilt to either side during the injury.

The outer frame 2 may be formed with a plurality of water inlet and outlet 13a at regular intervals. A plurality of water entrances and exits (not shown) may be formed in each of the inner frames 3 at regular intervals. However, it is preferable that one water outlet 13b is formed in each of the balance rich parts 4.

The outer frame 2 may be formed with a plurality of air valve (11a) at a predetermined interval. A plurality of air valves (not shown) cannot be formed in each of the inner frames 3 at regular intervals. However, it is preferable that one air valve 11b is formed in each of the balance rich parts 4.

The operation of opening or closing the air valves installed in the frames 2 and 3 and the balance rich part 4 or injecting air into them is performed by the control system 7. The control system is a separate device from the structure 1 and floats on the sea surface away from the structure. The control system is basically provided with an automatic valve 9 for opening and closing the air valve and a compressor 8 for injecting air into the frame and the balance rich part.

In normal times without typhoons, the structure floats on the sea surface. If a typhoon is expected, wind speeds should be detected to submerge the structure into the sea. Therefore, the anemometer 10 is connected to the automatic valve 9, the automatic valve is activated when the wind speed is detected over a certain speed.

First, if the wind speed is detected over a certain speed, the automatic valve 9 is operated to open all the air valves installed in the frame (2, 3) at the same time. When all the internal air of the frames 2 and 3 is discharged and water is injected, the frames 2 and 3 start to dive, and the balance rich man 4 floats on the sea surface. At this time, the automatic valve 9 opens all the air valves installed in the balance rich (4) at the same time.

Once all of the balance rich air is exhausted and water is injected, the balanced rich and the frame begin to dive again. All air valves installed in the frames (2, 3) is preferably connected to the automatic valve by connecting a single hose, it is preferable that all the air valves installed in the balance rich (4) is also connected to the automatic valve by a single hose. desirable. Eventually, the automatic valve connects the automatic valve by two hoses.

In order to float the submerged structure 1, the boat approaches the control system 7 and first closes all air valves. Compressor (8) is operated to first lift the balance rich (4). When the balance rich 4 rises, air is injected into the frames 2 and 3 continuously to float.

Frames 2 and 3 may be formed with a plurality of air inlets, but it is preferable to be connected to the compressor by one hose, and the air inlet formed on the balance rich part 4 is also preferably connected to the compressor by one hose. Do. Eventually the air inlet is connected to the compressor by both hoses.

Fig. 7 is a sectional view of the air valve of the present invention, Fig. 7A is a sectional view of the air valve in the open state, and Fig. 7B is a sectional view of the air valve in the closed state. The air valve is composed of a cylindrical housing 111, a balloon 114 acting as a valve, a pair of caps 112 and 113 assembled to the upper and lower parts for protecting the balloon. A bent portion may be formed inside the housing 111 for a sealing effect. A plurality of holes are formed in the caps 112 and 113 to allow air to pass therethrough. As shown in FIG. 7A, when the air in the balloon is discharged through the hose 5, the air valve is opened. When air is injected into the balloon, the air valve is closed.

When the cage farm structure of the present invention is submerged into the sea, a cover net (not shown) should be installed to cover the entrance of the cage to protect the fish inside the net. If no cover net is installed, the fish in the net 17 will go out into the sea when diving into the sea.

The cage farm structure of the present invention can facilitate the operation of feeding the feed into the fishing net while the person walks on it by installing wooden planks and the like above the cage.

When the fish in the fishing net 17 are to be grown and harvested, the fishing net containing the fish must be lifted. Fishing nets can be lifted by installing four to twenty ropes (not shown) on the sides of each fishing net and winding these ropes with a motor (not shown) on top of the cage.

The cage farm structure of the present invention can automatically submerge the fish cage structure to a certain depth in the sea in case of severe storms such as a typhoon, so that the fish can always be safely farmed, and in coastal areas as well as the usual depth of 30 It can be safely installed in offshore areas of ~ 40m.

An object of the present invention is to have a dive control function to float on the surface of the sea or to dive to a certain depth in the sea, and having a dive control function can be safely installed in coastal areas as well as offshore areas having a depth of 30 ~ 40m. In addition, it is possible to prevent the death of fish even if red tide occurs on the surface of the sea or a certain depth of the sea by installing in the deep sea area. In addition, it is possible to protect the fish from various diseases by installing it in the deep sea area, and further reduce the cost of treatment, and thus reduce the farming cost, and the structure that submerged or submerged the farm structure onto the sea surface. In this case, the structure is not tilted to either side The invention has the effect of providing a cage farm structure that can be submerged or floated while maintaining a horizontal state.
