Description

Technology Field

[0001] The present invention relates to a seafood farm using underground sea salt water, and more specifically, to a seafood farm using underground sea salt water that treats the salinity of sea salt water pumped from underground and circulates it into a fish tank, which is a space for cultivating seafood, thereby maintaining an optimal environment for cultivating seafood. Background Technology

[0002] The methods of collecting marine organisms for food are broadly divided into natural capture (hunting) and artificial farming. Here, artificial farming involves setting up a net at a point in the nearby sea to form an artificial boundary, and then confining and farming marine organisms within the range of this formed boundary.

[0003] Since such artificial farming allows for the artificial mass growth of marine organisms in their actual habitat and makes it easy to collect as many as needed, artificial farming is a widely practiced fishing activity in coastal fishing villages.

[0004] However, since artificial fish farms are established in the sea that is in direct contact with nature, they are inevitably directly affected by natural disasters and various other disasters. Since these effects have adverse effects on the marine organisms being farmed and cause them to die, artificial farming of marine organisms was not an easy sector of fisheries. Prior art literature

Specific details for implementing the invention

[0017] The terms used in the embodiments have been selected to be as widely used as possible, taking into account their functions in the present invention; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the corresponding description of the invention. Therefore, the terms used in the present invention should be defined not merely by their names, but based on their meanings and the overall content of the invention.

[0019] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0021] FIG. 1 is a cross-sectional view schematically illustrating an embodiment of a seafood farm according to the present invention, and FIG. 2 is a cross-sectional view schematically illustrating an embodiment of a salinity control tank configured in a seafood farm according to the present invention.

[0023] Referring to FIGS. 1 and 2, a seafood farm according to the present invention comprises: an underground seawater pump (10) that pumps seawater (S1) to be supplied through a supply pipe (UP) piped from an underground space (U) where underground seawater (S1) is buried to the surface; a filtering tank (20) that stores seawater (S1) for a specified period so that sludge and sand and gravel settle in the seawater (S1) discharged from the supply pipe (UP); a disinfection tank (30) connected to the filtering tank (20) by a first transfer pipe (P1) and stores seawater for a specified period so that the seawater discharged from the filtering tank (20) is chemically disinfected; and a salinity control tank (40) connected to the disinfection tank (30) by a second transfer pipe (P2) and stores seawater (S2) for a specified period so that the seawater (S2) discharged from the disinfection tank (30) is exposed to sunlight for salinity control. A fishery tank (50) connected to a salinity control tank (40) and a third transfer pipe (P3), which stores sea salt water (S3) transferred from the salinity control tank (40) and is configured to allow seafood to inhabit; and an air supply unit (60) that sprays air into the sea salt water (S3) stored in the fishery tank (50).

[0024] Each component of the seafood farm according to the present invention is described sequentially according to the process in which the buried sea salt water (S1) is utilized in the aquaculture tank (50).

[0025] The process of exploring underground sea salt water (S1) and pumping it into the ground is generally accomplished by identifying the location of the underground space (U) through underground exploration, inserting an anchor pipe (SP) into the underground space (U) during the drilling process, and inserting a supply pipe (UP) into the anchor pipe (SP) into the underground space (U). Therefore, when a sea salt water pump (10) is installed in the supply pipe (UP) and mechanical pumping is started, the sea salt water (S1) buried in the underground space (U) is transported to the surface through the supply pipe (UP).

[0026] The sea salt water (S1) transferred in this way has been mixed with numerous foreign substances in the silt for a long time, so it is transferred to a filtering tank (20) for filtering and stored for a designated period to separate the mixture of sludge and sand and gravel by sedimentation.

[0027] The sea salt water drained from the filtering tank (20) is transferred to the disinfection tank (30) via the first transfer pipe (P1) and is disinfected through antibiotic and chemical processes. In addition, in the disinfection tank (30), various organic and inorganic substances and other microorganisms that inhabit ordinary seawater are injected into the sea salt water to treat it so that it has the properties of seawater.

[0028] Meanwhile, the average salinity of underground sea saltwater (S1) is 15 to 17‰, whereas the average salinity of ordinary seawater reaches 30 to 40‰. Therefore, a process is required to treat the underground sea saltwater (S1) to match the salinity of ordinary seawater. The seafood farm according to the present invention controls salinity by a natural evaporation method using sunlight, rather than by a method of forcibly injecting salts such as sodium chloride (NaCl, also known as salt), magnesium chloride (also known as brine), calcium sulfate, and potassium sulfate. To this end, the sea saltwater (S2) drained from the disinfection tank (30) is transferred to a salinity control tank (40) through the second transfer pipe (P2) and supplied, and in the salinity control tank (40), the sea saltwater (S2) is exposed to sunlight for a specified period to forcibly evaporate water from the sea saltwater (S2). During this process, the sea salt water (S2) stored in the salinity control tank (40) gradually evaporates as shown in Fig. 2, and when the sea salt water (S3) has a salinity comparable to that of ordinary seawater, it is forcibly transferred to the aquaculture tank (50) through the third transfer pipe (P3) as shown in diagram (c) of Fig. 2.

[0029] The process of treating sea salt water in the filtering tank (20), the disinfection tank (30), and the salinity control tank (40), respectively, requires a relatively long time. Therefore, the supply of sea salt water to the aquaculture tank (50) cannot be continuous, and only after the salinity control of the sea salt water within the salinity control tank (40) is completed can the sea salt water be supplied to the aquaculture tank (50) in an amount equal to the capacity of the salinity control tank (40). To resolve this problem, the seafood aquaculture farm according to the present invention is configured such that at least two of the selected one or more of the filtering tank (20), the disinfection tank (30), and the salinity control tank (40) are configured, and the corresponding supply pipe (UP), first transfer pipe (P1), or second transfer pipe (P2) are branched toward the filtering tank (20), the disinfection tank (30), or the salinity control tank (40) configured with at least two. Accordingly, when the sea salt water (S1) buried in the underground space (U) is pumped and supplied to the surface, the sea salt water (S1) is transferred to a supply pipe (UP) branched to connect to an injectable filtering tank (20) among a plurality of filtering tanks (20). In addition, the sea salt water drained from the filtering tank (20) is transferred to a first transfer pipe (P1) branched to connect to an injectable disinfection tank (30) among a plurality of disinfection tanks (30). In addition, the sea salt water (S2) drained from the disinfection tank (30) is transferred to a second transfer pipe (P2) branched to connect to an injectable salinity control tank (40) among a plurality of salinity control tanks (40). Ultimately, since the treatment of sea salt water in the filtering tank (20), the disinfection tank (30), and the salinity control tank (40) is carried out without blockage according to the site conditions, the supply of sea salt water (S3) to the aquaculture tank (50) has relative continuity.

[0030] The aquaculture tank (50) stores sea salt water (S3) to allow seafood to inhabit. The seafood may include various fish, shellfish, and other birds that inhabit the sea and can be used for food. An environment similar to the seabed may be created within the aquaculture tank (50).

[0031] Since the seafood being farmed also needs to breathe, the air supply unit (60) sprays air into the sea salt water (S3) stored in the aquaculture tank (50) so as to increase or maintain the oxygen concentration of the sea salt water (S3) at a constant level.

[0032] Since the sea salt water (S3) stored in the aquaculture tank (50) becomes contaminated over a long period of time, the contaminated sea salt water (S3) is pumped from the bottom of the aquaculture tank (50) and transferred back to the ground, and the sea salt water (S3) transferred in this way is discharged to the outside through purification treatment. To this end, the fourth transfer pipe (P4) has its end piped to the bottom of the aquaculture tank (50), and further includes a purification pump (75) that pumps the sea salt water (S3) from the aquaculture tank (50) through the fourth transfer pipe (P4). Additionally, it further includes a purification tank (70) in which the pumped sea salt water (S3) is stored and purification treatment is performed.

[0033] Meanwhile, for a specific seafood being farmed, it is necessary to ensure that a constant flow is generated in the sea salt water (S3) stored in the aquaculture tank (50). However, if a propeller or turbine is used artificially to generate the flow of the sea salt water (S3), the rapid movement of the propeller blades or turbine blades may have an adverse effect on the seafood. Therefore, a technology to resolve this problem is described below.

[0035] FIG. 3 is a cross-sectional view schematically illustrating another embodiment of a seafood aquaculture farm according to the present invention, FIG. 4 is a schematic drawing illustrating one embodiment of an air supply unit configured in a seafood aquaculture farm according to the present invention, FIG. 5 is a schematic unfolded view showing the inner surface of a fish tank configured in a seafood aquaculture farm according to the present invention, FIG. 6 is a cross-sectional view schematically illustrating a part of a fish tank with a spray nozzle installed, and FIG. 7 is a plan view schematically illustrating the appearance of flow occurring in the sea salt water stored in the fish tank.

[0037] Referring to FIGS. 3 to 7, in order to generate a flow of stored sea salt water (S3) in the aquaculture tank (50) of the seafood aquaculture farm according to the present invention, the aquaculture tank (50) has an inner surface (50a) in the shape of a curve, and a concave air passage (51) is formed in a spiral shape along the inner surface (50a). The width of the air passage (51) itself and the pitch spacing between other air passages (51) located above or below the inner surface (50a) may vary depending on the volume, height, or cross-sectional area of ​​the aquaculture tank (50).

[0038] The air supply unit (60) comprises an air tank (61) for receiving air, an air pump (64) for pumping air from the air tank (61), a plurality of sub-pumps (65, 65', 65") each installed in at least two supply pipes (AP) branched out from the air pump (64) to pump air, a plurality of injection nozzles (62, 621, 622, 623) installed at arbitrary intervals along the ventilation passage (51) as shown in FIG. 5 and forcibly injecting air downward in the longitudinal direction of the ventilation passage (51), and a portion of the width of the ventilation passage (621, 622, 623) covered and closed by a certain distance starting from the placement position of the injection nozzles (621, 622, 623) so that the air injected from the injection nozzles (621, 622, 623) travels along the ventilation passage (51) for a certain distance or more. It includes a cover (63) formed so that one side is tapered so that the opening range of the passages (621, 622, 623) gradually widens. Thus, air is injected at high pressure through the powerful pumping of the sub-pump (65, 65', 65") and moves the sea salt water (S3) downward along the passage (51). Eventually, the sea salt water (S3) creates a flow by causing a screw at low speed but relatively low water pressure as shown in Fig. 7.

[0039] It is desirable to place a cover (63) so that the air sprayed into the ventilation passage (51) remains within the ventilation passage (51) without escaping, and at a distance where the water pressure gradually decreases, the opening of the ventilation passage (51) is expanded so that the air escapes the ventilation passage (51) and contributes to increasing the oxygen concentration of the sea salt (S3).

[0040] Since multiple spray nozzles (621, 622, 623) are installed at random intervals along the air passage (51), the thrust for the sea salt water (S3) stored in the aquaculture tank (50) is not actually small.

[0041] Meanwhile, the end of the third transfer pipe (P3) is positioned so that sea salt water is sprayed from the aquaculture tank (50) in the same direction as the air spraying direction of the spray nozzles (621, 622, 623), and further includes a water spraying pump (45) that pumps sea salt water (S3) from the aquaculture tank (50) at high pressure. Thus, through the aforementioned air spraying and sea salt water (S3) spraying, a flow can be created in the sea salt water (S3) stored in the aquaculture tank (50) without collision with seafood.

[0042] Meanwhile, the output of the sub-pump and the capacity of the air supply pipe are differentiated so that the injection nozzle placed in the deep layer of the aquaculture tank (50) can inject a relatively large amount of air at high pressure. Accordingly, in the aquaculture tank (50) where sea salt water (S3) is stored, a constant flow is generated in both the deep layer, where the water pressure is relatively high, and the surface layer, where the water pressure is relatively low.

[0043] Since the air passage (51) of the aquaculture tank (50) has a concave shape, various foreign substances can accumulate over a long period of time and form a closed section. Therefore, it is desirable to install a vibrator (80) to make the air passage (51) vibrate so that the accumulated foreign substances can be separated and the accumulation rate can also be reduced.

[0045] Although the detailed description of the present invention described above has been explained with reference to preferred embodiments of the invention, those skilled in the art or those with ordinary knowledge in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and technical scope of the invention as described in the claims set forth below.
