Automatic ups and downs cage form system {AUTO SUBMERSIBLE FISH CAGE SYSTEM}

The present invention relates to a cage farming system, and more particularly, to a submerged cage farming system that automatically sinks or floats to the surface according to the external environmental conditions.

In recent years, cage farming has been active.

In general, cage farming is a method of farming fish by forming an evacuation facility with various nets on the beach, away from land.

However, the conventional cage is installed in the near sea, but in recent years, the water quality is tending to advance to the far sea for farming in clean water. As a result, when the conventional cage facilities are used, the cages are damaged depending on the condition of the ocean such as blue, causing enormous damage to the fisherman.

In addition, there is a problem that it is difficult to secure a stable power unless the generator is installed in the distant sea.

Finally, because the location of the cage is away from the land, there was a problem that fisheries frequently visited and manually controlled the cage to check the status of the cage. In addition, poor sea conditions often result in the destruction of cage facilities by surges, since the manager cannot even access the cage.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention, in particular to detect the outside pressure or more than the threshold value that can be damaged according to the external environmental conditions, the cage is detected the cage It will provide an ups and downs cage system to automatically sink below the surface of the water and automatically raise it back to the surface when environmental conditions return to normal.

To this end, the automatic ups and downs cage farming system according to the present invention, the cage farming system, frame-shaped cages with a net for farming fish; A reinforcing device for reinforcing the frame constituting the cage; A mooring device for fixing the cage to a predetermined position on the surface of the water; Float into which gas or sea water flows in and out to increase or decrease the buoyancy to sink the cage below the surface or to rise to the surface; And a main control device that regulates the inflow and outflow of gas or seawater to the rich to automatically control the buoyancy to subside the surface or to automatically float to the surface.

According to the present invention, there is an effect of preventing the cage breakage by automatically sinking down the surface of the cage to prevent breakage according to external environmental conditions.

In addition, according to the present invention, by controlling the cage remotely from the remote location there is an effect that the controller does not have to move for the control of the cage style.

Finally, according to the present invention, the power used for the automatic control of the cage is liquefied gas, so it is also suitable for the marine environment difficult to secure power.

Hereinafter, with reference to the accompanying drawings will be described in detail the automatic ups and downs cage system according to an embodiment of the present invention.

The basic principle of the present invention is to sense the marine environmental conditions to prevent the breakage of the cages and to sink below the surface when the environmental conditions are poor and to rise to the surface again when the environmental conditions return to normal.

In describing the present invention, when it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic diagram showing an automatic ups and downs cage system according to an embodiment of the present invention.

Referring to FIG. 1, the automatic ups and downs cage system 100 according to the present invention includes a frame 110 having a frame 120 and a frame constituting the cage 110. A reinforcement device 130 for reinforcement, a mooring device 140 for fixing the cage 110 at a predetermined position on the water surface, one or more rich people 150 for maintaining or adjusting the buoyancy of the cage 110, and And a main control device 160 for controlling outflow of gas or seawater to at least one variable buoyant rich 152 to automatically control the cage 110 to subside below the surface of water or to automatically rise to the surface. It is configured by.

Referring to the operation of the automatic ups and downs cage system 100 according to the present invention configured as shown in Figure 1 as follows.

First, the cage 110 is fixed to a certain point of the ocean by at least four mooring device 140.

Here, the mooring device 140 sinks to a certain position of the ocean to fix the cage 110 by the mooring rope 141 and the buffering rope 142.

Referring to FIG. 2B, the shape of the cage 110 fixed to the surface of the water by the mooring device 140 may be confirmed.

Figure 2 is an exemplary view showing the operation of the automatic ups and downs cage system according to an embodiment of the present invention.

FIG. 2 describes the same reference numerals for the same members of FIG. 1.

Thereafter, the main control unit 160 detects the marine environment at the point where the cage 110 is located, and the value of the detected marine environment is a threshold that destroys the cage 110 or kills the fish inside the net 120. If judged, the cage 110 is lowered into the water.

Here, if the main control device 160 to briefly describe the operation of lowering the cage 110 in the water as follows.

First, the main control device 160 reduces the buoyancy of the cage 110 for the lowering of the cage 110.

Because the cage 110 to rise to the surface of the at least one float (Float) 150 must be filled with gas.

Therefore, in order to reduce the buoyancy it is necessary to discharge the gas of one or more Float (150) and inflow of sea water.

Here, although the position of the rich man 150 is shown on the upper end of the cage 110, the type and function of the rich man 150 will be described with reference to FIG. 3 for explaining an embodiment of the cage 110 model.

As such, when the buoyancy of the rich man 160 provided in the cage 110 is reduced, the cage 110 is positioned below the water surface by the main control device 160 with reference to FIG.

Because the external force due to the blue damage damaging the cage 110 decreases exponentially as it goes down the surface of the sea, if the cage 110 descends to a certain depth from the surface, the cage 110 may escape from the risk of breakage. In addition, since most of the red tide inhabitants of the water depth of about 10m from the surface of the cage 110 or more can be lowered to prevent the death of farmed fish.

Preferably, the threshold value is the density of numerical values and red tide creatures derived from various hydraulic model tests, numerical analysis, and strength tests when manufacturing the cage 110.

In addition, the marine environment sensed by the main control device 160 is preferably wind speed, wind pressure, water depth, water temperature, wave height and red tide information.

As such, when the cage 110 descends below the surface to avoid the external force, the main control device 160 continues to collect the marine environment at regular time intervals.

If the main control unit 160 collects marine environment information again, if it is determined that it is safe to raise the cage 110 again, it raises the cage 110 again.

This can be realized by reversing the operation of reducing the buoyancy for the lowering of the above-mentioned cage 110.

That is, since at least one rich man 150 provided in the cage 110 is filled with sea water, the seawater is discharged and the gas is supplied to increase the buoyancy of the rich man 150.

The cage 110 then rises back to the water surface by the main control device 160 as shown in FIG.

Therefore, it is possible to greatly reduce the probability that the cage 110 is damaged or the farmed fish dies due to external force and red tide creatures applied to the cage 110.

Preferably the main control device 160 is filling a fuel, such as liquid nitrogen.

Therefore, the main controller 160 vaporizes the liquid nitrogen and converts the gas into gas, and injects gas at a pressure sufficient to push the seawater of the rich 150 to the outside to increase the buoyancy by replacing the seawater.

In addition, unlike the cage 110, unlike the cage 110 is always located on the surface of the water can periodically transmit the status of the cage 110 and the environment information of the point where the cage 110 is located.

Therefore, the remote site can know if the material that is fueled in the rise of the cage 110, such as liquid nitrogen, or if there is a defect in the device for controlling the cage 110.

In addition, the cage may be injured or lowered based on the information received from the main control device 160 at a remote location.

Therefore, it is economical because the number of manpower for managing the cage moves to the point where the cage 110 is located through the vessel is very low.

3 is a detailed view showing the cage 110 and the main control device 160 of the automatic ups and downs cage system 100 in accordance with an embodiment of the present invention.

FIG. 3 describes the same reference numerals for the same members of FIG. 2 and FIG. 1.

3, the configuration of the cage 110 and the main control unit 160 of the automatic ups and downs cage system 100 according to an embodiment of the present invention is as follows.

First, the entire skeleton of the cage 110 is formed in a frame structure.

The skeleton consists of a combination of top (a), mid (b), bottom (c) and vertical (d) frames.

That is, the upper surface (a), the middle surface (b), the lower surface (c) frame forms a horizontal frame of the cage (110).

And it is provided with a complementary device 130 to complement the skeleton.

Complementary device 130 is located on the top of the cage 110, the upper inner ring frame for hanging the upper tension line 133 on the at least one clasp 152 and the upper tension line 133 in the upper edge of the cage 110 ( 131 and a lower inner ring frame 132 positioned under the cage 110 to surround the lower tension line 134 in the vertical frame e and cross the lower tension line 134 in the lower portion of the cage 110. .

As such, by providing the fastening lines 133 and 134 at the upper and lower edges of the cage 110, the structures of the frames a to d constituting the cage 110 can be strongly complemented.

As such, the frame of the cage 110 is formed of the frame and the supplementary device 130 for reinforcing the frame.

And at least one rich person 150 is provided to adjust the buoyancy of the cage.

The rich man 150 is composed of a fixed rich 151, an absolute rich 152, a variable rich 153.

The fixed rich man 151 means a rich man having a fixed buoyancy, the buoyancy is always constant.

Absolutely rich 152 means a rich man the controller can manually adjust the buoyancy.

The variable rich man 153 means a rich man who can adjust the buoyancy of the rich man in the main control device 160.

Therefore, the main controller 160 controls the variable rich 153 to increase or decrease the buoyancy of the cage 110 according to a preset threshold of the external environment.

That is, gas is injected to increase the buoyancy of the variable rich 153, and sea water is injected to decrease the buoyancy.

Referring to the buoyancy control of the variable rich 153 is as follows.

First, the main control device 160 detects whether the marine environment is above or below a predetermined threshold.

Since the description of the threshold is described in FIG. 1, it is omitted.

If it is above the threshold, the main control device 160 controls the internal buoyancy of the variable rich 153 through the control line 161.

Although one control line 161 is illustrated in one variable rich unit 153, the control line 161 is connected to each variable rich unit 153.

First, the buoyancy of the variable rich 153 is reduced in order to control the cage 110 positioned on the water surface to descend below the water surface.

To this end, the main control device 160 opens the passage so that the variable rich 153 can enter the sea water through the control line 161.

Thereafter, the main control device 160 opens a passage for discharging the gas filling the variable rich 153 to the outside through the control line 161.

Therefore, the variable rich 153 is the gas is discharged to the outside and the sea water is introduced to the buoyancy decreases to fall below the surface of the water.

On the other hand, the buoyancy of the variable rich 153 is increased in order to control the cage 110 which is lowered below the surface of water to rise up to the surface of water.

To this end, the main control device 160 opens a passage for discharging the seawater filling the variable rich 153 through the control line 161 to the outside.

Therefore, the seawater inside the variable rich 153 is discharged to the outside.

At this time, the discharge of sea water is made possible by converting the liquid nitrogen into gas by vaporizing the liquefied nitrogen in the main control device 160 and injecting the variable rich 153 to a pressure capable of discharging sea water to the outside.

As such, when all of the seawater is discharged into the variable rich 153 and the gas flows in, the variable rich 153 increases in buoyancy and floats to the surface of the water.

Here, the control line 161 is composed of a line for sending the gas to the variable rich 153 and a line for controlling the variable rich 153 with an electrical signal.

Preferably, the main control device 160 is connected to the cage 110 and always floats on the surface of the water.

To this end, the main control device 160 has a connection line 163 connected to at least one of the cages (110).

However, when the cage 110 rises to the surface, the connecting line 163 is stretched, which adversely affects the fish of the cage 110 and the net 120.

Thus, to prevent this, the main control device 160 is provided with an automatic winding means 162 to prevent sagging of the connecting line 163.

Preferably, the automatic winding means 162 has a constant elasticity so as to be automatically wound when the control line 161 and the connection line 163 are stretched.

This automatic control reduces the risk of damage to cages or the loss of farmed fish, enabling safe cage farming.
