1 is a view of a marine aquaculture cage facility according to a first embodiment of the present invention, FIG. 2 is a view for explaining the feeding operation of the marine cage of the facility of FIG. 1, and FIG. 3 is a sea cage of the facility of FIG. 1 It is a diagram for explaining the volume control operation of.

As shown in FIG. 1, the marine aquaculture cage facility 100 according to an embodiment of the present invention includes a fixed jacket structure 111, a

rotating device

113, 121, a marine cage 131, and an external force drag 141. And some or all of the marine observation device 181.

Here, "part or all" is included in the external force drogue 141 or the marine observation device 181 is omitted so that the edging facility 100 is configured, or some components such as the external force drogue 141 are marine edging It refers to a thing that can be integrated and configured with other components such as (131), and will be described as including all in order to help a sufficient understanding of the invention.

The fixed jacket structure 111 corresponds to a jacketed structure that is fixed to the bottom of the ocean so that a part of it is exposed outside the ocean. In the embodiment of the present invention, the fixed jacket structure 111 may be referred to as a jacketed fixed structure. The jacketed type is one of the fixed methods of offshore plant foundation structures. The jacket structure is a structure in which piles, that is, piles, are mounted on the sea floor, and decks (eg, horizontal and inclined reinforcements, etc.) are mounted on the jacket, and the deck of the jacket can be used as treatment facilities and residential facilities. It is a structure that can support wind or wave loads and its own weight as a huge pile is embedded in the sea floor, and the size and drying cost of the jacket structure rapidly increase according to the depth of water, so a depth of about 400m is the current limit. However, the size of the fixed jacket structure 111 according to the embodiment of the present invention may be adjusted depending on how the marine cage 131 is configured and operated by connecting it to the fixed jacket structure 111.

The sea cage 131 may have various shapes, such as a circle and a square, and includes a floating body 132, a lower support structure 133, a net 134, a volume control line 161, and a food supply device 191. Can include. As long as the floating body 132 can have buoyancy like a buoy, it is irrelevant in any shape, and a (wire) rope 142 passes through it, and feeds into the inside of the marine cage 131 A feeding device 191 for may be provided inside. It can be seen that the floating body 132 and the lower support structure 133 are connected by a net 134 and a volume control line 161. In order to adjust the volume of the net 134 of the maritime border 131, the lower support structure 133 is provided with a volume control line 161 so that the position can be moved.

As can be seen in FIG. 3, the volume control ship 161 is a volume control ship 161 when invasion of bad weather conditions such as red tide, typhoon, high water temperature, etc. By adjusting the height of the sea cage 131, it can be moved and reinstalled. In particular, when a typhoon invades and it is necessary to move the sea cage 131 into the bay, the depth of the bay is not deep, so it is necessary to temporarily reduce the height of the cage to operate in the bay. This is very important. Here, the volume control line 161 is made of a wire rope or a polypropylene (PP) rope, and electricity required to reduce the length of the rope is supplied through a motor (not shown) installed in the floating body 132. For example, the principle of a pulley for winding and unwinding the volume control line 161 may be applied to adjust the volume. When adjusting the rope length in order to move the sea cage 131, an operation command (or control command) is issued from a control system, that is, a control device installed in the central upper structure 171. After the height of the cage is reduced, it is towed by the vessel 162, and the towing rope 163 is connected and moved.

The feeding device 191 may include a pump and a feeding pipe. The food supply pipe starts from the central upper structure 171 and is connected to the connection support 121 and can be installed in eight directions as shown in 2 through the floating body 132 of the marine edging 131. . Of course, the installation method and number of installations can be adjusted as much as possible. A total of eight are located in eight directions on the floating body 132 of the sea cage 131, and the food supply is adjusted according to the direction of the tide. Since tidal current means the flow of seawater periodically occurring due to high tide and low tide, the central upper structure 171 analyzes tide data obtained through observation of the marine environment from a control device, for example, to analyze the main tidal current direction and velocity, and this data By using the pump inside the upper central structure 171 to supply food. Since the pump controls the amount of food supplied through pumping, in order to control the amount of food supplied, a valve may be installed in the feed pipe and electronically controlled to control the amount of food supplied. When the algae is weak, food is supplied through all directions, whereas, for example, when the algae is strong in a specific direction, the food is controlled to be supplied from a food supply pipe located in the opposite direction. Both the strength and direction of the pump can be controlled. In Fig. 2, A represents the direction of the tide, and B represents the direction of feeding food through a food supply pipe.

When waves, tide, and wind act, the sea cage 131 rotates freely in the direction in which the load acts, and moves in the direction in which the external force is minimized. An external force drogue 141 is installed on one side of the periphery of the sea ridge 131 so that the sea ridge 131 rotates better according to the external force, and the external force drogue 141 has a surface area and It consists of a relatively large volume. The external force drogue 141 and the marine edging 131 are connected by a light rope 142.

The upper part of the fixed jacket structure 111, more precisely, a central upper structure 171 equipped with a part of the food supply device 191, a data storage and control system, that is, a control device, is mounted on a portion exposed to the outside of the ocean. The control device configured in the upper central structure 171 collects the measurement data of the marine observation device 181 installed near the sea edge 131, analyzes the collected data, and analyzes the collected data, and based on the analysis result, the feed supply device It is possible to control the volume control line 161 of 191 and the like. For example, the control device can control the supply of food from the feed pipe in the opposite direction to the direction of the tide as mentioned above, and adjust the operation cycle of the pump according to the strength of the tide to control the amount and direction of the feed. I will be able to.

A marine observation device 181 is installed on the periphery of the seabed 131 on the seabed. The marine observation device 181 is equipped with a small photographing device such as a camera or a sensor to observe waves and tide, and transmits information to the upper central structure 171 through the submarine cable 182. The upper central structure 171 collects and analyzes data to analyze the characteristics of the surrounding marine environment. In particular, it automatically controls feeding by accurately analyzing the direction and intensity of birds. Of course, various data, such as meteorological data from a meteorological station, may be used to observe the marine environment at sea or underwater. For example, if meteorological information such as a typhoon can be involved in the operation of the volume control ship 161, data of the underwater marine observation device 181 can be related to food supply. Therefore, in the embodiment of the present invention, there will be no particular limitation on what kind of data is used. For example, the government can establish a marine network underwater (e.g., composed of a data sink in the water and a number of sensors communicating around it), and collect and utilize a lot of marine information through the underwater sensor. It may be possible to receive and use data as much as possible. Moreover, by configuring the upper central structure 171 to enable wireless communication, automatic operation for observing ocean conditions may be possible as much as possible.

For example, in recent years, deep learning technology using artificial intelligence has developed a lot, so the control device analyzes the collected big data to predict the impact on the maritime border 131 in advance, and tells the manager of the maritime border 131 in advance. The facts can be notified so that appropriate action can be taken. For example, data is continuously collected in relation to the maritime border 131, and as the collected data increases over the years, efficient and safe operation of the maritime border 131 using big data and artificial intelligence may be possible.

4 is a diagram of a marine aquaculture cage facility according to a second embodiment of the present invention.

As shown in Fig. 4, the maritime surface edging facility 200 according to the second embodiment of the present invention is efficiently configured by connecting a plurality of floating maritime edgings 131 in series to a fixed jacket structure 111. As a form cage system, it includes a fixed jacket structure 111, a rotating device (113, 121), a plurality of sea cages (131A, 131B, 131C) connected in series with each other, some or all of the external force drag (141), , Here, "including some or all" is the same as the previous meaning.

Compared with the maritime aquaculture cage facility 100 of FIG. 1, the maritime aquaculture cage facility 200 of FIG. 4 has a difference in that a plurality of

maritime cages

131A, 131B, and 131C can be connected in series with each other. can see. Here, "connected in series" means that the second marine edging (131B) is connected to the first marine edging (131A) based on the fixed jacket structure 111, and the third marine edging again to the second marine edging (131B) (131C) means the structure to be connected.

When configured in this way, in the case of a large number of marine edgings (131A, 131B, 131C), the edgings (131A, 131B, 131C) are connected using a light rope 142, and the size of the external force drogue 141 receiving an external force Also increases. In other words, the connection between the maritime borders (131A, 131B, 131C) is connected by the rope 142, and above all, the external force drag 141 provided on one side of the third maritime border (131C) located at the outermost is Compared to 1, its size gradually increases in proportion to the number of connected

maritime borders

131A, 131B, and 131C. This is because the marine edgings (131A, 131B, 131C) located between the fixed jacket structure 111 and the external force drogue 141 are floating on the sea surface by the floating body 132, but the marine edging of FIG. 4 compared to FIG. 1 Since a larger external force (eg, gravity) is generated in (131A, 131B, 131C), the size of the external force drag 141 is increased in consideration of this. The larger the area, the greater the external force, so it can be considered that this is considered.

Except for the same points as described above, the details related to the maritime aquaculture cage facility 200 of FIG. 4 are not significantly different from the content of the maritime aquaculture cage facility 100 of FIG. 1, so the contents will be substituted.

anchor devices

155 and 156 that are built into the bottom of the water, where "including some or all" is the same as the previous meaning. .

As can be seen in (a) and (b) of FIG. 5, a plurality of marine edgings (131A, 131B) can be connected to the fixed jacket structure 111 using a connection support bar 121 to maintain the position. . On the other hand, the floating body 132 of the marine edgings 131A and 132B is supported using a mooring line 155 and an anchor 156 on the outside of the fixed jacket structure 111. While the food for aquaculture is stored inside the central upper structure 171, the automatic feed supply is automatically supplied to the inside of the cage through the riser system (or riser device) 151, the submarine pipe 152, and the food supply riser 153. do. Although different submarine pipes 152 may be configured to provide food supply, a plurality of submarine pipes 152 classified in one automatic feed supply riser system 151 are configured, and each submarine pipe 152 It regulates the supply path to be supplied to. A valve or switch may be configured and controlled at the beginning of each submarine pipe 152 classified as a representative.

Since food must be automatically supplied by monitoring and analyzing the condition of the fish being farmed, an underwater camera (not shown) may be further located inside the

marine cages

131A and 131B. By analyzing the current state of the surrounding tidal currents of the

marine cages

131A and 131B through the marine monitoring system, food is controlled to be supplied in a direction opposite to the tidal flow direction.

At the end of the food supply riser 153, a device capable of rotating the automatic feed supply direction control device 154 in a direction of 360 degrees may be installed so as to adjust the direction in which food is supplied. This is controlled by the upper central structure 171 to supply food, and the feed is supplied by a pump, and the strength of the pump is determined according to the size of the algae. Control of the automatic feed supply direction control device 154 may be possible by connecting the rotating gear to the drive shaft of the motor and then controlling the motor.

Except for the above, since the marine aquaculture cage facility 300 of FIG. 5 is not much different from the marine aquaculture cage facility 100 of FIG. 1, the contents will be substituted.
