Description

Sinking and rising type fish cultivation cage of open-sea using floating type ocean wind power generator}

The present invention relates to a floating offshore wind power generator in which a wind power generator is located at the upper part of the sea level along with a floating structure, and sea water is placed to a predetermined depth on the center side of the lower surface of the center support of the floating structure that supports the tower post of the wind power generator at the bottom. A guide post extending in the middle is connected and installed, and the sinking and rising operation of the cage aquaculture equipment is guided by the guide post, while a feeding passage for sedimentable feed through the inner space of the cage rig is also provided based on the guide post. This is about a sinking floating type open sea cage aquaculture device using a floating offshore wind power generator.

In general, marine cage aquaculture equipment is designed to cultivate various types of fish by installing cage nets in water areas such as coastal waters or the open sea. The exchange of seawater and the supply of oxygen are carried out smoothly through the cage nets. Of course, waste products and feed residues generated during the metabolic process of farmed fish are also automatically discharged to the outside through the cage water, and the water quality inside the cage water does not deteriorate even if a large amount of fish is cultivated at high density, so in terms of large-scale fish farming, It can provide several beneficial advantages.

Despite the various advantages mentioned above, due to the nature of cage nets being installed at sea, there is a high risk of being exposed to natural disasters such as typhoons and red tides, and the periodic and stable supply of feed is also difficult due to the ship-based approach. There were some disadvantages, and as a result, offshore cage aquaculture equipment has been mainly installed in the inner bays of coastal waters, which are not greatly affected by natural disasters and are easily accessible. However, recently, due to water pollution in coastal waters, cage aquaculture equipment has been installed. Measures to install it in open seas are being explored.

As a representative example, the sinking-floating type open-sea cage aquaculture device allows the cage aquaculture device to float above sea level in normal times and sink to seawater when a typhoon or red tide occurs. It is known that the applicant has previously applied for and registered patents (No. 10-1185861 and 10-1448808) under Patent Application No. 97912 in 2011 and Patent Application No. 117773 in 2013, and the sinking flotation device and feeder of the cage aquaculture equipment are used at sea. It is known that installation and operation in connection with a wind power generator is described in Korean Patent Publication No. 10-2021-0058211.

As described above, the wind power generator as a base for installing a cage aquaculture device in the open sea is known to have a tower post installed vertically from sea level to a certain height and a power generation unit built in. A nacelle connected and installed at the top of the tower post to allow relative rotation, a hub installed to be rotatable at the front end of the nacelle while connected to the input shaft of the power generation unit, and a radial hub along the outer peripheral surface of the hub. It consists of at least two blades that are connected and installed.

In addition, the wind power generator is mostly of a fixed type in which a tower post is connected with a transition piece interposed on the upper side of a monopile pressed into the seafloor to a predetermined depth, In Korean Patent Publication No. 10-2021-0058211, which is referred to as prior art, the cage aquaculture device is installed to sink and float along the monopile of this fixed wind power generator, while the cage aquaculture device is installed from a feeder installed inside the tower post. Feed was supplied using a feeding hose extending to the cage water side.

However, since the above-mentioned fixed offshore wind power generators are mainly installed in sea areas with a water depth of about 30 to 40 m, the cage aquaculture equipment installed based on the monopile of the wind power generator is also limited to a water depth of about 30 to 40 m. There was no choice but to sink and float, which made it somewhat difficult to operate the cage aquaculture equipment more safely from the effects of high temperatures in the summer as well as natural disasters such as typhoons and red tide.

In particular, due to the influence of high temperatures in the summer, it is almost impossible to cultivate high value-added cold climate fish species such as bluefin tuna and grouper, which prefer water temperatures as low as 18℃, and common fish species that can be easily cultured in coastal waters cannot be cultivated in cage culture equipment in the open sea. Despite the considerable costs required for the facility and operation of cage culture equipment, the actual income through shipment and sale of farmed fish was very low, which further increased the economic burden on fish farmers. there was.

On the other hand, as the feeder installed inside the tower post of the wind power generator and the cage water of the cage aquaculture equipment are connected with a flexible feeding hose, changes in sea level and waves due to the difference in tides occur. There was a problem with the feeding hose not being able to stably maintain its straight shape and easily bending in an unspecified direction due to the shaking of the feeding hose, etc. As a result, feed was trapped in the curved part of the feeding hose and stagnated, etc. Undesirable problems have arisen in terms of fixed-quantity feeding, which involves accurately adding a fixed amount of feed.

It is desirable to distribute it through the controller 40, and if the function can be achieved, the controller 40 can be installed in other internal spaces of the tower post 1 or the inside of the nacelle 2 in addition to the machine room. It is possible, and various other auxiliary facilities, such as an auxiliary feed storage bin (17a), can be additionally installed inside the machine room, and the worker's access passage through the machine room remains the passage already provided in the floating offshore wind power generator. It can be utilized, or a separate passage can be additionally provided.

It is desirable to install a railing 26 along the edge of (24), and the self-buoyancy of the cage aquaculture device 20 is set to have a negative buoyancy (sedimentation force) slightly lower than the neutral buoyancy, so that the cage aquaculture device 20 It is desirable to minimize the power of the drum motor 31 or the amount of compressed air required for levitation.

In addition, the feed supply path applied to the present invention so that sedimentable feed can be supplied into the cage net 23 of the cage aquaculture device 20 is that of the guide post 13, as shown in FIGS. 4, 5, and 8. It is provided by a feed supply pipe 19 that extends vertically downward for a predetermined length along the internal space, and the feed supply pipe 19 is preferably arranged in the form of a double pipe in the center of the guide post 13, and the feed It will be installed so that the upper entrance of the supply pipe 19 passes through the bottom surface of the center support 5 and lies below the feed outlet of the feed feeder 16, that is, the front end exit of the fixed dose dispenser 18.

To this end, the upper surface of the guide post 13 may be formed as an opening and the opening may be installed to penetrate the center of the bottom surface of the center support 5. However, as shown in FIG. 8, the guide post 13 A flange-type cover plate (13a) is installed on the upper side so that the cover plate (13a) is additionally fastened to the bottom surface of the center support (5), and the upper inlet side of the feed supply pipe (19) is connected to the cover plate. It is preferable to install it so that it penetrates the central part of (13a), and the lower outlet of the feed supply pipe (19) is connected to the wall of the guide post (13) based on a location selected from among the sinking and floating positions of the cage aquaculture device (20). It will be installed to communicate with the inner space of the fence net (23) through the part.

As described above, since the lower outlet of the feed supply pipe 19 is exposed to seawater, seawater flows in at a certain level along the feed supply pipe 19, but the upper entrance of the feed supply pipe 19 is open to the outside through the machine room ( Since atmospheric pressure is applied), the sea water level inside the feed supply pipe 19 is limited to a level almost similar to sea level or slightly higher, and the capillary at the level through which sea water flows into the machine room along the feed supply pipe 19 This phenomenon does not occur, and sedimentation feed is used because the feed must be introduced into the cage net (23) through the feed supply pipe (19) into which seawater flows.

If necessary, the feed supply pipe (19) immediately below the reinforcement support (15) is overloaded so that the seawater that has risen to the relevant location due to the rise in water level during high tide can be discharged to the outside of the guide post (13). A flow pipe may be installed, and it is preferable to install the overflow pipe slanted upward across the space between the feed supply pipe 19 and the guide post 13 to prevent sedimentation feed from escaping with seawater along the overflow pipe. , It is desirable to prevent seawater from flowing into the inner space of the guide post 13 for the installation of the injection pump and the wiring of the cable, etc., which will be explained later.

In addition, the portion where the lower outlet of the feed supply pipe 19 communicates with the internal space of the cage fish 23 is based on a position selected from the sinking position and the floating position of the cage fish farming device 20. It is desirable to ensure that it is at the top of the inside of the feed pipe (19), and the reason is to maximize the sedimentation distance (fall distance) of the feed introduced into the cage net (23) through the outlet of the feed supply pipe (19) so that the farmed fish can consume the feed. This is because sufficient time can be provided, that is, enough time for the feed to remain inside the cage net 23.

In addition, when the lower outlet of the feed supply pipe 19 is installed according to the floating position of the cage aquaculture device 20, the overall length of the feed supply pipe 19 and the settling time of the feed can be shortened, but the Considering the fluctuation range of the water level of the sea level, the outlet location must be adjusted to the lowest height of the sea level at low tide, so there is a disadvantage that the feed input location changes frequently depending on the water level of the sea surface, and the lower outlet of the feed supply pipe 19 is connected to the cage aquaculture device. When installed according to the sinking position of (20), the overall length of the feed supply pipe (19) and the sinking time of the feed become long, but the feed input position is kept constant at the optimal position regardless of changes in the water level of the sea level. There is an advantage.

It is desirable to finally determine the outlet location of the feed supply pipe 19 by considering the above-mentioned advantages and disadvantages, so that the sedimentable feed supplied to the inner space of the cage net 23 can be distributed more evenly in the space. 8 to 10, at least two (a total of four in the drawing) feed distribution pipes (28) are radially inclined downward in the direction of the wall of the guide post (13) on the lower side of the feed supply pipe (19). It is preferable to connect and install, and the outlet side of each feed distribution pipe (28) communicates with the inner space of the cage net (23) through the wall portion of the guide post (13).

As described above, it is possible to more reliably perform uniformly distributed input of sedimentable feed using the feed distribution pipe 28, while at the bottom of the feed supply pipe 19 to which each feed distribution pipe 28 is connected. In order to prevent unnecessary accumulation of feed on the surface, the bottom surface of the feed supply pipe (19) excluding the portion where each feed distribution pipe (28) is connected is formed into an opening, and then the cone-shaped distribution cover (29) is formed through the opening. ) is preferably inserted in a fitting manner, and the distribution cover 29 will be integrally assembled or welded with the lower portion of the feed supply pipe 19.

More preferably, as shown in FIGS. 11 and 12, the injection pipe is provided with a suction pipe 43 and a discharge pipe 44 of seawater inside the space provided between the guide post 13 and the feed supply pipe 19. With the pump 41 installed together with the pump motor 42, the tip inlet side of the suction pipe 43 is exposed to the seawater through the wall of the guide post 13, and the discharge pipe 44 is It penetrates the wall of the feed supply pipe 19 and then extends vertically downward for a predetermined length along the central axis direction of the feed supply pipe 19, and a foreign matter filter is installed inside the tip entrance of the suction pipe 43. desirable.

Through the above-described method, the feeding operation of the sedimentable feed that is introduced from the feed supply pipe (19) through each feed distribution pipe (28) into the inner space of the cage net (23) is performed in a more efficient and reasonable pressurized distributed spraying form. This can be done, and in the drawing, the injection pump 41 is placed with the pump motor 42 on a holder 45 connected horizontally between the feed supply pipe 19 and the guide post 13. , the pump motor 42 is connected to the controller 40 by a cable (not shown) introduced into the machine room through the cover plate 13a on the upper side along the space between the feed supply pipe 19 and the guide post 13. It will be connected and installed.

In addition, when the injection pump 41 is installed at the floating position of the cage aquaculture equipment 20 together with the feed distribution pipe 28, the inlet side of the suction pipe 43 is below the floating deck 21 (sea level). However, when the injection pump 41 is installed at the sinking position of the cage aquaculture equipment 20 together with the feed distribution pipe 28, as shown by the dotted line in Figures 11 and 12 , the inlet side of the suction pipe 43 can be penetrated at any position of the adjacent guide post 13 wall, and each feed is attached to the distal end of the discharge pipe 44 of the injection pump 41 as shown in the direction of the arrow in FIG. 12. It is desirable to install a spray head (44a) capable of spraying seawater radially along the passage space provided by the distribution pipe (28).

On the other hand, in order to reliably achieve the input of sedimentable feed through the feed supply pipe 19 and the feed distribution pipe 28, a cage net 23 installed only on the outside along the cage frame 22 is applied. However, in this case, a predetermined gap must be maintained between the guide hole 24 of the floating deck 21 and the bottom plate 27 and the guide post 13 to ensure smooth sinking of the cage aquaculture equipment 20. Due to the structural characteristics that must be provided, there is a very high risk that small-sized farmed fish will escape out of the cage net 23 through the gap space.

Due to the above-mentioned factors, farmed fish could not be raised by introducing them into the cage net 23 from the fry stage, and the inconvenience of having to grow the fry for a certain period of time in an indoor fish farm on land or a cage fish farm in coastal waters arose. In order to prevent this inconvenience, if the gap between the guide hole (24) and the guide post (13) is made too narrow, it will interfere with the smooth sinking and floating operation of the cage aquaculture device (20), and the floating deck (21) ) and the guide hole 24 of the bottom plate 27 are connected to the vertical cylindrical net 23a, the input operation of the settling feed is significantly interfered with by the mesh structure of the cylindrical net 23a.

Of course, it is possible to inject sedimentary feed to a certain level into the inner space of the cage net 23 through the cylindrical net 23a using the injection pump 41 described above, but the injection pump 41 Even when applied, it is not possible to completely prevent the phenomenon of a part of the settling feed colliding with the mesh of the cylindrical net (23a) and then settling downward along the space between the cylindrical net (23a) and the guide post (13). As a result, unnecessary waste of feed is caused as the feed escapes to the outside of the cage net (23) through the gap between the guide hole (24) of the bottom plate (27) and the guide post (13).

Focusing on the above situation, the inner peripheral surface of the guide hole 24 of the floating deck 21 and the floor plate 27 is connected with a vertical cylindrical net 23a as shown in FIG. 11, while the guide post 13 The sinking position and floating position of the cage aquaculture device 20 are passed through the guide hole 24 of the floating deck 21 through the cylindrical net 23a and the guide hole 24 of the bottom plate 27. An upward water flow that suppresses the fall of sedimentary feed into the inner space of the guide post (13) corresponding to the inner lower side of the cage net (23) based on a selected position among the cage nets (23) and induces re-inflow into the cage net (23). An injection pump (41) for composition was additionally installed.

In the case of the injection pump 41 for creating an upward water flow as described above, it is provided with a seawater suction pipe 43 and a discharge pipe 44 and is installed in the inner space of the guide post 13 together with the pump motor 42. , the pump motor 42 will be connected to the controller 40 by a cable (not shown) introduced into the machine room through the cover plate 13a on the upper side of the guide post 13, and the injection pump 41 When installing at the floating position of the cage aquaculture device (20), it is desirable to provide a separate holder (45) on the inner side of the wall of the guide post (13), and the corresponding spray pump (41) is installed on the cage aquaculture device (20). ), it is desirable to arrange the injection pump 41 and the pump motor 42 on the upper side of the bottom of the guide post 13, as shown by the dotted line in FIG. 11.

In addition, the inlet of the suction pipe 43 of the injection pump 41 for forming an upward water flow can be exposed to seawater through the wall of the adjacent guide post 13 or the bottom of the guide post 13, and the injection pump for forming an upward water flow The discharge pipes (44) of (41) are radially connected and installed on the distribution head (41a) provided at the discharge port of the injection pump (41) in a number of at least three, and each discharge pipe (44) is connected to the distribution head (41a). After extending from (41a) upwardly toward the wall side of the guide post (13), the outlet of each discharge pipe (44) penetrates the wall of the guide post (13) and faces the lower part of the cylindrical net (23a). It is placed to be seen.

Just in the same manner as above, the feed that settles downward along the space between the cylindrical net (23a) and the guide post (13) can be pushed upward using the seawater current injected at an upward angle from each discharge pipe (44). However, so that the seawater sprayed from each discharge pipe 44 can form a strong water current in the vertical direction, each discharge pipe 44 exit and It is more preferable to install the water flow control plate 46 or the water flow control sheet according to the facing position, and the water flow control plate 46 or the water flow control sheet is integrally connected or glued to the mesh portion of the cylindrical net 23a. .

As an additional matter, as shown in FIG. 13, at least two or more (a total of four in the drawing) sterilizing lamps 47 are radially arranged along the outer peripheral surface of the guide post 13, so that the inside of the cage net 23 It is desirable to allow sterilization of seawater in parallel, and each sterilization lamp (47) is installed inside a part of the wall of the guide post (13) so as not to interfere with the sinking of the cage aquaculture equipment (20). In the state of being inserted into the concave lamp receiving part 48, the controller 40 is introduced into the machine room through the cover plate 13a on the upper side along the inner space of the guide post 13. ) is connected and installed.

The sterilizing lamp 47 may be a rod-shaped ultraviolet ray lamp having a predetermined length as a representative example, but any type may be used as long as it can sterilize seawater, and the location where the sterilizing lamp 47 is installed is It is desirable to use the guide post (13) corresponding to the inner center of the cage net (23) in accordance with the selected position among the sinking or floating position of the cage culture device (20), and if necessary, the cage culture device ( It is also possible to arrange all of the sterilizing lamps (47) according to the sinking and floating positions of 20).

On the other hand, the water temperature, dissolved oxygen (DO), and salinity of the open sea area where the cage aquaculture device 20 of the present invention is installed are measured by water depth to determine whether the cage aquaculture device 20 is sinking or floating and feeding feed. In order to more accurately determine whether the Like the sterilizing lamp 47 described above, the sensor unit is also inserted into the sensor storage portion in which a part of the wall of the guide post 13 is concave inward, and is positioned at the top along the inner space of the guide post 13. It will be connected to the controller 40 by a cable introduced into the machine room through the cover plate 13a on the side.

It is most economical to use the water temperature sensor alone as the sensor unit, but select at least one of several sensors that can detect conditions other than water temperature, such as a DO sensor, salinity sensor, and turbidity sensor, to use the water temperature sensor and the water temperature sensor. It is also possible to install them together, and instead of installing the sensor unit directly on the guide post (13), the present applicant applied for patent application No. 87289 in 2014 and patent application No. 98908 in 2021, and applied for patent application No. 10-1531321 and 10-2311739. We would like to clarify that it is also possible to install each patented marine observation buoy in the sea area surrounding the cage aquaculture device (20) and utilize the data transmitted from the observation buoy.

According to the present invention, which has the above configuration, the water temperature is around 18°C, which is suitable for breeding high-quality cold-temperature fish species such as bluefin tuna and grouper using the deep water depth (100-150m) of the open sea where floating offshore wind power generators are installed. It is possible to naturally secure a water depth layer of at least 50 m or more, while using the feed supply pipe (19) inside the guide post (13) to guide the sinking and rising of the cage aquaculture device (20) from the water depth layer to the sea level. It is possible to supply settling feed to the inner space of the cage net (23).

Through this, the cage aquaculture device 20 can be submerged to a water depth of at least 50 m or less, thereby maximizing the influence of high summer temperatures as well as natural disasters such as typhoons or red tides, and the inside of the guide post 13 By using the feed supply pipe (19) installed in the form of a double pipe, it is possible to accurately inject a fixed amount of feed at a set time, allowing high value-added fish species such as bluefin tuna and grouper to be safely reared in an efficient and economical manner. It can greatly contribute to increasing the income of farmed fish through the shipment and sale of farmed fish.

In addition, a plurality of radial feed distribution pipes 28 provided at the lower end of the feed supply pipe 19 and an injection that sprays seawater from the lower center side of the feed supply pipe 19 through each feed distribution pipe 28. By using the pump 41, the feeding operation of sedimentable feed through the internal space of the cage net 23 can be performed in a more efficient and reasonable pressurized distributed spraying form, so that the form introduced into the cage net 23 It can promote healthy and even growth of fish.

In addition, by arranging the sterilization lamp 47 and the sensor unit on the concave storage space provided at a random position on the outer surface of the guide post 13, the sinking and floating operation of the cage aquaculture device 20 is not hindered. By performing sterilization and monitoring work on the seawater inside the cage net 23 under conditions that are (23) Farmed fish introduced into the system can be raised more healthily and safely.

In particular, since it is possible to fundamentally block the phenomenon of cultured fish escaping into the gap space between the guide post 13 and the guide hole 24 by using the cylindrical net 23a, the fish can be stored from the fry stage to the adult stage. In addition to making it possible to raise farmed fish over a wide period of time, some of the feed that was not input into the cage net (23) from the feed distribution pipe (28) through the cylindrical net (23a) is transferred to the cylindrical net (23a). While sinking along the space between the guide post 13 and the guide post 13, the cylindrical net 23a is guided again to the inner space of the cage net 23 by riding the upward water current caused by the injection pump 41 and the water flow control plate 46. Unnecessary feed loss due to application can also be minimized.
