Description

  In the event of an emergency disaster such as a red tide or a typhoon, the present invention enables the body of the sacrifice to sink to a certain depth with a simple machine operation, thereby damaging aquaculture facilities due to waves, red tides, etc. In addition to making it possible to prevent damages such as these, the aquaculture facility can be easily operated even in the open sea area, and the sinking operation of the ginger body is made more effective and quick while simplifying the overall structure of the sinking device. The present invention relates to a subsidence type fish farming apparatus using an underwater motor that can be carried out and can easily perform the position grasping and restoration of the sinked ginger body by a display float.

  In general, a ginger is a facility in which various aquatic products such as fish are confined to grow for a certain period of time, stored for a short period of time for shipping adjustment, or temporarily stored for direct sales to consumers. To tell. There are various types of cages, such as the well-known net-type cages, box-type cages like aquariums, or tank-type cages for transportation and storage, and shellfish like molluscs and shellfish as well as fish. It is also used for aquaculture and the growth of juveniles, fry and fry.

  As shown in FIG. 1, a net-type sacrifice facility installed on a near sea area for cultivating fish is a sacrifice facility 1 by connecting a pair of steel bars, steel bars or high-strength PVC bars in the horizontal and vertical directions. A lattice frame that forms the foundation of A working step 3 is formed by binding a plywood or a wood board integrally with the lattice frame on the upper surface of the lattice frame. A PVC float 4 is attached to the lower part of the work platform 3 so that the lattice frame floats on the water surface together with the work platform 3. A bag-shaped net 2 is connected to the inside of the lattice frame and is installed so that the bottom of the grate is submerged in seawater by a sushi 5. The sacrifice facility 1 installed in this way is connected by an anchor 6 and a rope 7 that fix the outer edge of the lattice frame to the sea bottom so that it does not flow due to the flow of waves or tidal water.

  In the conventional sacrifice facility 1 that is mainly installed in the near sea area using the net 2, the seawater inside and outside the sacrifice can freely pass through the mesh of the net 2, so that the exchange of seawater and the supply of oxygen are made smooth. In addition, the waste from the metabolic activity of the cultured fish and the remaining residue of the cultured fish sink to the bottom of the sea through the mesh, so there is no need to separately remove and separate the waste and debris. Therefore, even if a large amount of fish is cultivated inside the net 2 in a narrow space, the water quality in the ginger does not deteriorate rapidly, and therefore it can be easily applied to large-scale aquaculture.

  However, the conventional sacrificial facility 1 has a wave frame like the Tokai (Sea of Japan) because the lattice frame that forms the foundation and the work platform 3 are connected and fixed by the anchor 6 and the rope 7 fixed to the sea bottom. When installed in a place where the area is relatively intense and rough, or in a seawater area where the waves are severe, the lattice frame and the work platform 3 may not be able to withstand the impact of the waves, or the PVC frame may be crushed from the work platform 3 There was a problem that the sacrificial facility 1 could be easily damaged, such as 4 being detached.

  Since the conventional sacrifice facility 1 can be used only on the relatively weak south coast and the nearby sea, there is a problem that it is not possible to advance to an open sea fishing ground that has higher water quality and higher productivity than the nearby sea, and the aquaculture farms are concentrated in a specific area. Therefore, there was a problem that the water quality in the near sea was rapidly polluted by a large amount of waste and food left from the farm.

In the event of a natural disaster such as a typhoon or red tide, it is necessary to move the sacrifice facility 1 to a safe place by using a ship. There was a risk of serious damage.

When the anchor according to the present invention is used while being fixed to the sea bottom, the anchor is fixed to the sea bottom within a relatively early time, and the support strength of the sacrifice body by the anchor can be improved.

Hereinafter, the content of the present invention will be described in detail with reference to the drawings.
FIGS. 2A and 2B are side views showing a sinking fish farming apparatus according to an embodiment of the present invention, and FIGS. 3A and 3B according to another embodiment of the present invention. It is a side view which shows a subsidence type fish farming apparatus.

The overall structure of a subsidence type fish farming apparatus using an underwater motor according to the present invention is as shown in FIGS. 2 and 3, and an opening is provided in the center of the upper part, and a bag-shaped net 12 is provided. A management float 13 for obtaining buoyancy is integrally connected to the net 12 at the upper opening of the.
The middle frame 11 and the sacrifice body 10 are connected to the lower part of the management float 13. The middle layer frame 11 maintains the shape of the net 12 together with the tension rope 15, and the sacrifice body 10 floats on the water surface by the buoyancy of the management float 13.

  A display float 20 having buoyancy is attached to the center of the management float 13 so as to float on the water surface, and a hydraulic hose 26 extends from the bottom of the display float 20 to the inside of the sacrifice body 10. In the embodiment of FIG. 2 (a), since the device for winding the hydraulic hose 26 inside the display float 20 is not installed, the hydraulic hose 26 is maintained in a zigzag form inside the sacrifice body 10 before the sacrifice body 10 sinks. ing. In the other embodiment of FIG. 3 (a), a device for winding the hydraulic hose 26 is installed inside the display float 20. Therefore, even before the sacrificial body 10 sinks, the hydraulic hose 26 keeps the interior of the sacrificial body 10 straight. It penetrates. The internal structure of the display float 20 for entraining the hydraulic hose 26 will be described in more detail in the following description.

A hydraulic hose 26 extended from the display float 20 is coupled to the underwater hydraulic motor 31 at the bottom of the sacrifice body 10. A number of tension ropes 15 for supporting the net 12 are coupled to a rope wheel 34, and the rope wheel 34 is attached to a settlement device 30. An anchor 40 is fixedly installed on the sea bottom just below the subsidence device 30. The anchor 40 is connected to the rope wheel 34 via a sinking rope 44.
The submersible hydraulic motor 31 is actuated by the hydraulic pressure flowing in through the hydraulic hose 26, and the sinking rope 44 is wound around the rope wheel 34, so that the sacrifice body 10 is kept at a certain depth as shown in FIGS. 2 (b) and 3 (b). You can sink.

Hereinafter, the contents will be described in more detail with reference to FIGS.
4 (a) and 4 (b) are a front sectional view and a side sectional view showing a preferred embodiment of a display float used in the subsidence fish farming apparatus of the present invention. A body rod 23 including a buoyancy chamber 24 is formed inside the display float, and a plug post 22 and a control ball 21 are integrally formed and attached to the upper portion of the body rod 23. The control ball 21 is provided with a coupler panel 25 for connecting a hydraulic device, and has a hydraulic injection socket 25a, a hydraulic discharge socket 25b, and a leakage discharge port 25c.

  The coupler panel 25 preferably uses a quick-coupling that is the most quick and convenient to disassemble and assemble among various means capable of supplying hydraulic pressure from the hydraulic device to the submersible hydraulic motor 31. . In the quick coupling, the plug on the hydraulic device side is inserted into the sockets 25a and 25b installed on the coupler panel 25 by inserting, and at the same time the valve seat of the plug is pushed by the valve seat of the socket 25a and 25b supported by the spring. The flow path is opened, and the structure and type of such a quick coupling corresponds to a technical matter already known.

  The leakage pressure discharge port 25c formed at the center of the coupler panel 25 is configured to automatically discharge the leaked hydraulic pressure from the coupler panel 25 to the submersible hydraulic motor 31 through the hydraulic hose 26 to the outside. This is to prevent the underwater hydraulic motor 31 from being stopped or broken. The inside of the hydraulic hose 26 is a triple pipe structure in which a hose pipe connected to the lower side of the hydraulic injection socket 25a and the hydraulic discharge socket 25b of the coupler panel 25 and a hose pipe communicating with the leakage pressure outlet 25c are independent of each other. It has become. A lid 21a is installed on the control ball 21 into which the coupler panel 25 is inserted so that seawater does not flow through the coupler panel 25 so that it can be opened and closed with a hinge.

The hydraulic hose 26 extends from the coupler panel 25 of the control ball 21 to the lower part of the display float 20 through the plug post 22 and the body rod 23, and is directly connected to the submersible hydraulic motor 31 of the subsidence device 30.
Before the sacrificial body 10 sinks, the hydraulic hose 26 is zigzag inside the sacrificial body 10 because the length of the hydraulic hose 26 is longer than the distance between the display float 20 and the submersible hydraulic motor 31 as shown in FIG. Although maintained in the form, even in such a case, there is no significant effect on the settlement operation of the ginger body 10 and the culture of fish confined in the ginger body 10.

  In order to further rationalize the sinking of the sacrificial body 10 and its restoring operation to further secure an effective space within the sacrificial body 10, the hydraulic hose 26 is extended from the display float 20 when the sacrificial body 10 is sinked. When the lift is restored, the hydraulic hose 26 is automatically wound inside the display float 20. For this purpose, a machine room 27 partitioned separately from the buoyancy chamber 24 is formed inside the fuselage rod 23, and an auto-winder wheel 28 (Auto-winder wheel) of the hydraulic hose 26 is installed inside the machine room 27. It is desirable to do.

  The auto-winder wheel 28 is the same system as an industrial tape measure, a film winder of a photographic machine, or a winder generally applied to various automatic winding systems, and a pair of brackets on both side walls of the machine room 27. 28b is installed, and the fixed shaft 28a is installed on the bracket 28b. A spiral spring (not shown) is provided inside the right fixed shaft 28a and the auto-winder wheel 28 in FIG. 4A, and the auto-winder wheel is moved when the sacrificial body 10 is lowered by the operation of the sinking device 30. As the hydraulic hose 26 is fed out by rotating 28, a spiral spring installed therein is elastically wound around the fixed shaft 28a. When the sacrificial body 10 is lifted and restored, the force wound around the spiral spring is removed and the spiral spring is elastically released from the fixed shaft 28a. Is supposed to wind up.

  The auto-winder wheel 28 can easily adjust the load that the hydraulic hose 26 is fed out of the auto-winder wheel 28 by adjusting the type of spiral spring and its elastic force. In the case of the present invention, the hydraulic hose 26 is easily drawn out even with a force less than the buoyancy of the display float 20, and the display float 20 is raised by the force that the hydraulic hose 26 is drawn out when the sacrifice body 10 sinks. Along with that, it will not sink.

  4A is provided with a wheel casing 29 for supporting the rotation of the auto-winder wheel 28. A hydraulic hose 26 extending from the coupler panel 25 through the plug post 22 is provided with the wheel casing 29. And is connected to the center side of the auto-winder wheel 28. One end of the hydraulic hose 26 wound around the auto-winder wheel 28 is rotationally connected to the hydraulic hose 26 passing through the wheel casing 29, so that the auto-winder wheel 28 can be connected from the coupler panel 25 regardless of the rotation of the auto-winder wheel 28. The hydraulic pressure can be transmitted to the hydraulic hose 26 wound around. A pair of guide rollers 26 a for lowering the hydraulic hose 26 directly below the display float 20 is installed on the lower side of the machine room 27.

FIG. 5 is a perspective view showing a connection structure of a sacrifice body and a sinking device used in the sinking type fish farming apparatus of the present invention. As shown in FIG. 5, the management float 13 coupled to the upper part of the net 12 (not shown) has a hollow disc and the trunk itself forms a working platform. The body is made of a material having buoyancy, for example, a material such as high strength PVC or a styrofoam covered with a cover, so that the sacrifice body 10 is automatically levitated on the water surface.
A handrail 14 for safety of workers is installed on the outer peripheral edge of the management float 13, and the net fixing port 17 is provided on the inner peripheral edge of the trunk so that the hollow portion 18 of the management float 13 can be covered with a net. Is installed.

  The middle layer frame 11 for maintaining the shape of the net 12 is made of a pipe and is formed in a circular or polygonal shape (preferably 6 to 12 corners). By extending a number of tension ropes 15 for fixing the net 12 from the management float 13 to the lower part through the intermediate layer frame 11, the net 12 can be maintained in the form of the intermediate layer frame 11. By fixing the rope wheel 34 of the sinking device 30 to the lower end of each extended tension rope 15, the sinking device 30 is coupled to the sacrifice body 10 integrally. The middle frame 11 can also be manufactured using a material having a buoyancy or a hollow pipe so that the load of the sinking device 30 connected to the lower part of the sacrifice body 10 can be supported together with the management float 13.

  The rope wheel 34 that forms the foundation of the subsidence device 30 has a body plate 341 through which the submersible hydraulic motor 31 penetrates at the center thereof, and a large number of joints integrally formed with the body plate 341 on the outer peripheral edge of the body plate 341. Frames 343 are arranged radially. A ring-shaped wheel frame 342 is integrally formed at the outer end of each connection frame 343, and a connection ring 16 that is coupled to the tension rope 15 of the net 12 is formed integrally on the upper surface of each connection frame 343.

  FIGS. 6 and 7 are a front sectional view and a bottom perspective view of a waist puller showing a sinking device according to an embodiment of the present invention. The submersible hydraulic motor 31, the speed reducers 32 and 32 ', and the bearing case 33a are installed through the body plate 341 of the rope wheel 34, and a rotor is provided on the output shaft 33 of the submersible hydraulic motor 31 protruding below the rope wheel 34. 35 disc bodies 351 are fixed. A winding roller 36 that rotates following the wheel frame 342 of the rope wheel 34 is installed at the tip of the roller arm 352 extending from the disc body 351.

A central roller 39 is installed below the disc body 351 of the rotor 35. The central roller 39 winds a sinking rope 44 extending upward from an anchor 40 fixed to the sea bottom. The bracket 353 attached to the tip of the roller arm 352 of the rotor 35 is provided with first and second direction changing rollers 37 and 38.
When the submersible hydraulic motor 31 operates and the rotor 35 rotates together with the winding roller 36, the sinking rope 44 passes through the center roller 39, the first and second direction changing rollers 37 and 38, and the winding roller 36. And the sinking device 30 sinks into the water together with the sacrifice body 10.

  In the present invention, in FIG. 7, a hollow rail pipe 344 is installed in close contact along the wheel frame 342 of the rope wheel 34, and a ratchet portion 36 b that meshes with the rail pipe 344 is formed on the winding roller 36. The roller shaft 36a is rotated around the rail pipe 344. However, any roller structure may be applied as long as the take-up roller 36 can rotate following the wheel frame 342. The structure of the roller for winding the sinking rope 44 from the central roller 39 through the winding roller 36 into the wheel frame 342, the number of installation and the installation position thereof are not limited to those shown in the drawings, and various types of roller structures are possible. Applicable.

  FIG. 8 is a front sectional view showing another embodiment of the subsidence apparatus used in the subsidence type fish farming apparatus of the present invention. A rotor 35 is installed below the body plate 341 of the rope wheel 34 so as to be rotatable about a rotation shaft 354. Instead of penetrating the submersible hydraulic motor 31 at the center of the body plate 341 of the rope wheel 34, the submersible hydraulic motor 31 is directly connected to the winding roller 36 installed at the tip of the roller arm 352 of the rotor 35. On the upper surface of the body plate 341 of the rope wheel 34, a rotating body 35 ′ for connecting a hydraulic hose 26 extending from the display float 20 through the sacrifice body 10 to an underwater hydraulic motor 31 directly connected to the winding roller 36 is rotatable. It is installed in.

  When the submersible hydraulic motor 31 is directly connected to the take-up roller 36, the wheel frame 342 itself of the rope wheel 34 serves as a reducer for the submersible hydraulic motor 31, so that the submersible hydraulic motor 31 having a relatively large capacity has speed reducers 32, 32. It is possible to use a submersible hydraulic motor 31 having a smaller capacity than the subsidence device 30 according to an embodiment in which 'is connected in two stages. For this reason, it is possible to simplify the overall structure of the subsidence device 30 and reduce the production cost of the fish farming device.

  FIG. 9 is a front sectional view showing a preferred embodiment of an anchor used in the subsidence fish farming apparatus of the present invention. A metal arm 42 protrudes in all directions from the lower side of the concrete body portion 41 and is integrally formed with the body portion 41, a flange 43 is formed at the center of the body portion 41, and a sinking rope is formed at the bottom of the flange 43. A rotating wheel 45 for fixing 44 is installed. Instead of the anchor 40 having such a configuration, a general anchor used for fixing a sacrifice can also be used. However, in the anchor according to the present invention, as the arm 42 digs deeply into the sea bottom with the passage of time, various floating substances are deposited on the anchor 43, so that the anchor 40 is fixed to the sea bottom early and the anchor 40 There is an advantage that the support strength of the sacrifice body 10 can be further improved.

  Hereinafter, the operation of a subsidence type fish farming apparatus using an underwater motor according to the present invention will be described in detail with reference to the accompanying drawings.

  First, in the state where there is no forecast of typhoon or red tide and the waves are not so severe, as shown in FIG. 2 and FIG. 3A, the salmon body 10 is floated on the water surface by the buoyancy of the management float 13 of the sacrificial body 10. . Then, an operator can enter the management float 13 of the ginger body 10 and perform a general operation such as feeding the cultured fish. In the present invention, the sacrifice body 10 is connected to the anchor 40 fixed to the bottom of the sea by a single sinking rope 44, so that the impact caused by the waves can be effectively absorbed. Further, since the sacrifice body 10 is reinforced by the middle layer frame 11 and the tension rope 15, it can be operated not only in the near sea area but also in the outside sea area where the waves are severe.

  When a forecast such as a typhoon or red tide appears and the sacrificial body 10 is to sink, a portable hydraulic device or a medium or small hydraulic device is loaded on the boat and carried to the sacrificial body 10. After the operator enters the management float 13 and covers the hollow portion 18 of the management float 13 with a lid mesh, the lid 21a installed on the control ball 21 of the display float 20 is opened as shown in FIG. 25 is exposed. When the hydraulic hose plug of the hydraulic device loaded on the boat is inserted through the hydraulic sockets 25a, 25b of the exposed coupler panel 25, the underwater hydraulic pressure of the subsidence device 30 passes through the display float 20 and the hydraulic hose 26 of the sacrifice body 10 from the hydraulic device. The hydraulic pressure can be supplied to the motor 31.

  When the hydraulic device is operated, hydraulic pressure is applied from the hydraulic device to the submersible hydraulic motor 31 of the subsidence device 30 through the hydraulic hose 26, and the submersible hydraulic motor 31 is activated. 6 and 7, the rotor 35 fixed to the lower end output shaft 33 of the submersible hydraulic motor 31 is gradually rotated at a speed reduced by the reducers 32 and 32 '. As a result, the take-up roller 36 installed at the tip of the roller arm 352 of the rotor 35 also rotates following the wheel frame 342 of the rope wheel 34 and rotates from the lower center roller 39 of the rotor 35 to the bracket 353 at the tip of the roller arm 352. The sinking rope 44 is wound around the wheel frame 342 via the first and second direction changing rollers 37 and 38 and the winding roller 36 installed in the wheel frame 342.

  In the case of the sinking device 30 in FIG. 8, a hydraulic hose 26 that penetrates the rotating body 35 ′ of the rope wheel 34 is connected to one side of the submersible hydraulic motor 31 that is directly connected to the winding roller 36. Since the submersible hydraulic motor 31 directly rotates the take-up roller 36 by supplying hydraulic pressure through the hydraulic hose 26, the rotor 35 and the rotating body 35 ′ rotate together with the take-up roller 36 and are installed below the rotor 35. The sinking rope 44 is wound around the wheel frame 342 through the first and second direction changing rollers 37 and 38 and the winding roller 36 installed on the bracket 353 at the tip of the roller arm 352 from the central roller 39 thus formed.

  When the sinking rope 44 is wound around the wheel frame 342 of the rope wheel 34, the sacrifice body 10 sinks to a certain depth as shown in FIGS. 2 and 3B. However, since the sinking device 30 is in a floating state, the rope wheel 34 tries to rotate in that direction by the force by which the sinking rope 44 is wound. The rope wheel 34 is not only integrally connected to the sacrifice body 10 by the multiple tension ropes 15 but also the entire load of the sinking device 30 is pulling the sacrifice body 10 downward. The force with which the sinking rope 44 is wound is much smaller than the force to rotate. As a result, the sinking rope 44 is easily wound around the rope wheel 34, and the sinking operation of the sacrifice body 10 is performed without difficulty.

  If the sacrificial body 10 is submerged about 10 to 15 m from the sea surface, it will escape from the sphere of influence of waves and red tides. Since the diameter of the rope wheel 34 is about 4 to 5 m, the sacrificial body 10 quickly sinks to the required depth by simply rotating the winding roller 36 following the rope wheel 34 and rotating it about once or twice. it can. In the case of the display float 20, it can rotate from the water surface, and the sinking rope 44 is also connected to the anchor 40 by a rotating wheel 45. Therefore, the entanglement phenomenon between the hydraulic hose 26 and the sinking rope 44 due to the operation of the sinking device 30 does not occur, and the sinking operation of the sacrifice body 10 can be performed more rationally and safely.

In the case of FIG. 2, the zigzag state of the hydraulic hose 26 that has been maintained in a zigzag shape before the sacrificial body 10 sinks disappears as the sacrificial body 10 sinks.
In the case of FIG. 3, the hydraulic hose 26 is fed out from the auto-winder wheel 28 of the display float 20 simultaneously with the sinking of the sacrifice body 10, but the display float 20 is kept floating on the sea surface even after the sinking body 10 sinks. Is done. Thus, the position of the sacrificial body 10 sunk by the display float 20 can be quickly and accurately grasped even after the sacrificial body 10 is sunk.

  The sacrifice facility of the present invention sinks the sacrifice body 10 to a required depth only by a simple mechanical operation in which a hydraulic device is connected to the coupler panel 25 installed on the control ball 21 of the display float 20 to operate the submersible hydraulic motor 31. Therefore, it is possible not only to prevent damage such as damage to the sacrifice facility due to a typhoon or red tide and mass death of cultured fish, but also to simplify the entire structure of the settlement device 30 for the settlement of the sacrifice body 10.

  In addition, even when an alarm such as a typhoon or red tide is released with the sacrificial body 10 settling down and the sacrificial body 10 is to be raised and restored again, the sacrificial body 10 is displayed by the display float 20 floating on the sea surface. The position can be grasped and the restoration work can be performed quickly. Such a restoration operation of the sacrifice body 10 is performed by using a boat or the like in the same manner as the subsidence operation, and then the lid 21 installed on the control ball 21 of the display float 20 after reaching the position where the display float 20 floats. Is connected to the coupler panel 25 of the control ball 21 by connecting a portable hydraulic device installed in the boat or a medium or small hydraulic device. At this time, by connecting the coupler panel 25 to the hydraulic device in a direction opposite to the connection direction when the sacrifice body 10 is lowered, the submersible hydraulic motor 31 can be operated in the direction opposite to that when the sinking device 30 is depressed. At the same time as the sinking rope 44 is fed out from the wheel 34, the sacrificial body 10 is raised and restored to the sea level by the buoyancy of the management float 13 of the sacrificial body 10.

  The present invention has been described in detail with reference to the embodiments. However, the present invention is not limited to the embodiments, and so long as it has ordinary knowledge in the technical field to which the present invention belongs, without departing from the spirit and spirit of the present invention, The present invention may be modified or changed.
