Description

Technical Field [0001] The present invention relates to a submersible cage system for fish farming,

The present invention relates to aquaculture technology of aquatic animals and relates to a cage aquaculture device of International Patent Classification A 01 K 61/00. More specifically, the present invention relates to a breeding facility and a cage apparatus belonging to aquatic animal culture related to a cage aquaculture apparatus having a four-sided screening device for harmful creatures outside a cage mold frame.

The production of aquatic products in Korea is more than 50%. Most of these aquaculture production facilities are located on the coast near the coastline. The reason that the aquaculture production farm is located in the coast is convenient because it is easy to manage with a close distance, but it is easy to maintain the facility because of the low flow of birds, and it is possible to install it at low cost, have.

For large-scale aquaculture facilities, aquaculture farms are being discussed, and some aquaculture facilities may be installed and operated in offshore distances more than one mile from the coast. However, due to the high cost and difficulties in management, most aquaculture facilities are installed around the coast, and these coastal aquaculture facilities have the effect that the organic matter contained in the sewage introduced from the land enters the farm as it is. Although such an effect has many advantages, it is very difficult to formulate remedial measures in case of red tide.

Red tide is generally called red tide in the sense of red water because it is often reddish, but the actual color changes depending on the color of the plankton causing it. Orange, reddish brown, brown, etc. This is because the creatures causing red tide have carotenoids like red and brown pigments in addition to chlorophyll. Phytoplankton such as diatom and dinoflagellate are the most common plankton causing red tides, and red tide standards in Korea also use the amounts of these two plankton. In addition, cyanobacteria (cyanobacteria), prototypes (noctiluca), and protozoan (mesodinium) may occur in the red tide.

When red tide occurs, the concentration of oxygen dissolved in the water is lowered, so that the fish and shellfish breathing using oxygen in the water suffocate and die. In addition, there are some cases where plankton is physically suffocated by fish gills, and there are some algae that are toxic among the plankton causing red tides, which are dead due to this toxicity. Because of this, when red tide occurs, it may not only hurt fishery, especially aquaculture, but it may also cause symptoms of poisoning by ingesting fish and shellfish that accumulate toxic substances.

The reason for the difficulty in remediation in the event of breeding in the inland waters near the coastline is that there is a restriction on the use of the loess application method, which is a representative red tide remedy method currently implemented, directly affecting the aquaculture fish, It is very slow. The slow rate of diffusion of red tide organisms due to slower tidal currents increases the density of red tide organisms in the same area, thereby increasing the damage of the aquaculture fish. The cause of suffocation is mainly due to oxygen depletion due to oxygen consumption of the red tide organism and the mucus of the red tide organism is adsorbed on the gill of the aquaculture fish and the fish can not breathe.

In Korea, the farms are concentrated in the inland waters near the shoreline, so that it is easy to inflow the red tide farms, which causes a great deal of damage when red tide occurs. However, the damage of red tide can be greatly reduced if countermeasures are established in advance and the prevention activities are reduced. According to the Ministry of Maritime Affairs and Fisheries, after the biggest red tide damage occurred in 2013, the "Red Tide Full-Year Comprehensive Measures" were established and executed. As a result, the damage decreased every year and the red tide damage decreased to about 5.3 billion won in 2015.

Currently, red tide remedies include spraying loess and red tides (four types approved by the sea) or diluting the sterilized water in seawater and re-discharging the water. Reducing the density of red tide creatures by dispersing seawater in the red tide . Horticultural spraying is the most common red tide remedy, but there are some opposing opinions such as secondary pollution, waste of resources, and controversy about harm.

In recent years, red tide remediation using electric stimulation has been sought to minimize the risk of secondary contamination of the marine environment due to red tide remedies and to reduce direct waste of resources. The sterilization water redistribution method that generates sterilized water by using electric energy and discharges it after mixing with water in the red tide area is one of very effective remedies. The sterilization water red tide salvage method is to supply the electric energy to the water in which the red tide is generated, thereby changing the physical properties of the water to kill the red tide organism. This method has a very high efficiency of remediation compared to the method of loess spraying and other methods, especially the risk of secondary contamination is very low. However, there are disadvantages such as excessive remediation cost and large remediation facilities, and it is urgent to research for applying them to red tide remediation efficiently.

Birds near coastal farms move at a very late rate, so harmful organisms, including red tide, on coasts occur on all four sides of the farm. In order to relieve these types of harmful organisms, ships equipped with relief devices should be circulated around the farm. However, in reality, it is not desirable to operate a long-time vessel around a narrow farm in a circular manner, not only in terms of safety but also in cost and efficiency. For more efficient relief in coastal aquaculture, hazardous bioremediation must be carried out on four sides of the farm, and the peak use of electrical energy for the rescue of harmful organisms should be limited and the electrical stimulation signal should not be harmful to the aquaculture.

This red tide remedy method by electric stimulation is characterized by less occurrence of secondary pollution than the yellow clay foaming method. However, since there is inherent risk of damage to fish caused by electric stimulation within electric stimulation range for harmful biological remedy, it is necessary to install a mesh to block the access to fish around the electrode outputting electric stimulation signal, It is operated by a limited number of streets.

The present invention, 'a device for restraining the four sides of a caged aquaculture poultry farm', is provided with an electrode for electric stimulation signal for poultry rescue on all four sides of a farm, thereby relieving harmful organisms generated in the vicinity of the farm. A low-cost, high-efficiency red tide salvage system for farms with low peak usage of electrical energy without causing damage to fish was constructed.

FIG. 1 is a view showing a development of a main body case front of a cage aquarium of the present invention, and FIG. 2 is a view showing an appearance of a main body case. A total of 12 three-phase contactors were used to control 24 electrodes for remediation. A more detailed description follows.

1. Structure

3 is a schematic diagram showing the configuration of the cage aquaculture apparatus of the present invention. The 'cage aquaculture device' of the present invention comprises a power supply device 1, a power supply device 2, a circulating contact output device, and an electrode. The 'cage aquaculture device' of the present invention is characterized in that a sequential output method is applied to limit the peak usage of electric energy, and electric stimulation signals are simultaneously output on two sides for quick relief, Two fully-isolated power supplies operate simultaneously.

2. Power supply

4 is a schematic view showing a power supply unit of the cage aquaculture apparatus of the present invention. The power supply device 1 and the power supply device 2 have the same configuration. Power supply 1 and power supply 2 are electrically isolated from the same power source through Transformer T1, which has a very high insulation resistance. The value of electrical insulation of the power supply 1 and the power supply 2 electrically isolated by the transformer T1 is about 100 MΩ or more, which means that the output of the two power supply devices does not cause any electrical short circuit. More detailed operation is as follows.

When AC220V, which is a general power source, is input to the transformer T1, 12V 1A of the circuit driving power and 25V 100A of the red signal are output to the secondary side of the transformer T1. The red tide relief electric signal 25V 100A is rectified by the diodes D1 and D2 and charged to the output capacitor C1. At this time, the voltage becomes E = 25 * √2 = 35.35VDC. 35.35 VDC are input to the electromagnetic contactors MC12 and MC2 connected in parallel with each other.

In the electromagnetic contactors MC1 and MC2, the drive coils are connected to the contact B of the other side so that they can not be driven simultaneously, and only one electromagnetic contactor is necessarily driven. The outputs of MC1 and MC2 are connected in parallel with opposite polarities. This configuration means that the polarity of the output is inverted according to the electromagnetic contactor operating among the electromagnetic contactors MC1 and MC2.

FIG. 5 is a schematic view showing the operation of the electromagnetic contactor MC1 of the cage aquarium of the present invention, and FIG. 6 is a schematic view showing the operation of the electromagnetic contactor MC2 of the cage aquarium according to the present invention. The electromagnetic contactor MC1 operates to output the electric signal for redeye relief with +/- polarity. The electromagnetic contactor MC2 operates to output the polarity of the polarity of the reversed electric signal for red-eye relief. The repetitive operation of the electromagnetic contactors MC1 and MC2 generates an AC power source having a constant frequency, thereby preventing the electrode from being burned down and solving the problems caused by the use of the DC power source.

7 is a schematic diagram showing a twin timer circuit for driving the electromagnetic contactors MC1 and MC2. The operation of the electromagnetic contactors MC1, MC2 is determined by a twin timer. When power is applied to the TWIN TIMER, the TWIN TIMER outputs the AC voltage to the A contact. The AC voltage output to the TWIN TIMER A contact is applied to the contactor through the contact B of the magnetic contactor MC1. MC2. ≪ / RTI > When an AC voltage is applied to the coil of the electromagnetic contactor MC2, the electromagnetic contactor MC2 is driven to output an electric signal - / + for redeying relief. When the electromagnetic contactor MC2 is operated, the B contact of the electromagnetic contactor MC2 is turned off, and the electromagnetic contactor MC1 becomes impossible to drive. This operation prevents the breakdown of the circuit due to the short circuit caused by the simultaneous operation of the electromagnetic contactors MC1 and MC2.

When the time set in the TWIN TIMER is completed, the TWIN TIMER switches the output to the B contact. When the output of the TWIN TIMER is switched to the B contact, it is inputted to the coil of the electromagnetic contactor MC1 through the contact B of the electromagnetic contactor MC2. When an AC voltage is applied to the coil of the electromagnetic contactor MC1, the electromagnetic contactor MC1 is driven to output an electric signal +/- for redeying relief. At this time as well, when the electromagnetic contactor MC1 is operated, the B contact of the electromagnetic contactor MC1 is turned off and the electromagnetic contactor MC2 becomes impossible to drive.

3. Circular contact output device

8 is a schematic diagram showing a circuit for generating an operation signal of the circulating contact output device. The present invention 'a cage aquaculture device capable of blocking four sides of harmful creatures' is realized with a total of 24 electrodes. Depending on the size of the farm, the number of electrodes can be variable. Twenty-four electrodes are grouped into three, and twelve pairs of electrodes are stacked to eliminate gaps in harmful organisms. Each set is operated by three phase magnetic contactors, and the total number of the contactors is 12 according to the 12 electrodes of the electrode. Twelve electromagnetic contactors were assembled in total of six with a magnetic contactor operating opposite electrodes to improve the speed of relief. This means that all of the remediation signals are output to 24 electrodes with a total of 6 output signals, which means that it takes 18 seconds to rescue four sides of the farm if 3 seconds is required per signal.

As shown in FIG. 8, the circuit for generating the operation signal of the circulating contact output device includes a timer S1 for generating a basic redeye recovery time of 3 seconds, an IC1 4017 for generating the initial signal every 6 times by dividing the signal of the timer S1, IC2 2003, which amplifies the output signal of IC1 and drives relay, and relay. The user sets the time of the timer S1 according to the density of the red tide. The longer the timer time, the greater the relief efficiency and the longer the four-sided relief time. When the signal of the first timer S1 is inputted, IC1 outputs Q0. When the signal of the timer S1 is inputted again after 3 seconds, IC1 outputs Q1. Whenever the timer S1 signal is input, IC1 outputs Q1 → Q2 → Q3 → Q4 → Q5. When the signal of timer S1 is input again, IC1 outputs Q6. Q6 is connected to IC1 reset (reset) And then IC1 outputs Q1. This operation is repeated infinitely for every six timer signals.

9 is a schematic diagram showing a relay circuit for operating an electromagnetic contactor in accordance with an output of a circuit for generating an operation signal among circulating contact output devices. The relay circuit is a total of six sets, each of which drives two electromagnetic contactors.

10 is a schematic view showing an electrode connected to an electromagnetic contactor of a cage aquarium according to the present invention. Since each electrode is operated in superposition, there is no space for remedy.

4. Electrode

11 is a view showing a configuration of a single-sided pest control 100 of a cage aquarium according to the present invention. The electrode was made of stainless steel electrode containing silver and installed vertically. And a buoy 140 is provided at the lower end to provide a weight 150 and a buoyancy at the upper end so that the structure of the electrode can be stably floated on the sea surface. Electric wires are drawn out from each electrode and fixed to the electrode holder 130 and the electrode holder 131, and extend vertically below the cage farm. The electrode holder 130 is fixed to the upper electrode frame 110 and the lower electrode holder 131 is fixed to the lower electrode frame 111 so that the gap between the upper and lower electrode frames 110, ). The weights 150 are placed under the lower electrode frame 111 so that the gap between the upper electrode frame and the lower electrode frame is kept constant and the electrode 120 is allowed to act in a certain range without being influenced by the flow around the farm.

The electrodes 120 are disposed at regular intervals and perpendicular to the water surface. The distance between the electrodes is determined by the distance between the electrode holders. In this case, since the electrode for harmful biohazard and the electric energy are used in pulse form in which strong impact energy is easily generated by using AC 60 Hz electricity, it is characterized by using an AC power source for generating a strong impact. There are many kinds of electrical stimulation signals used in red tide remedy using electrical stimulation. However, by using 60Hz pulsed alternating current power, it is easy to generate strong impact energy and it is possible to maintain persistence of relief. Such a pulse method has a low relief speed but is easy to use even in a region where the strength is high and the resistivity is low.

FIG. 12 is a view showing a configuration of a device 400 for blocking four pests of a cage aquarium according to the present invention. The electrode is composed of a cage pond at the center and one side surrounded by four sides of the pest control (100). At this time, the electrodes 120 are maintained at a constant interval, and the operation regions of the respective electrodes are overlapped and operated, so there is no space for remedy.
