FIG. 7 is a side view of another embodiment of the same invention.

  Hereinafter, the breeding method of the floating and sinking ginger and fish and shellfish in the present invention will be described in detail.

  As shown in FIGS. 1 and 2, a circular frame 1 on the inner peripheral side and a circular frame 2 of the same diameter are arranged concentrically at a predetermined interval T up and down, and the circumference of these frames 1 and 2 At the plurality of locations along the line, the frames 1 and 2 are connected by the vertical rod members 3 in the vertical direction, and the outer circumference circle on the outer circumference side larger in diameter than the frame 2 at the same level position as the lower frame 2 The frame 4 is arranged concentrically, and at the installation position of the vertical rod 3, the circular frame 2 and the outer peripheral circular frame 4 are concentrically connected by the horizontal rod 5 in the radial direction, and the vertical rod At the installation site 3, the circular frame 1 and the outer peripheral circular frame 4 are connected by the inclined rod member 6 from the upper circular frame 1 toward the outer peripheral circular frame 4, and a high strength annular ring of truss structure Group of To form a frame 10. In addition, it is preferable to use a galvanized steel pipe in terms of corrosion resistance as a constituent material of the basic frame 10 such as the frames 1, 2 and 4 described above.

  Between the lower circular frame 2 and the outer peripheral circular frame 4, a pair of float holding members 11 and 11 are connected and fixed in a radial direction between the two frames 2 and 4 at nine positions along the circumference. The resin floats 12 (9 pieces) are connected and fixed to the lower side of the float holding members 11, 11, respectively.

  The float 12 is formed by processing a lightweight resin into a hollow cylinder of the same shape and size, filling the inside with air or other gas, and having the same buoyancy. These floats 12 are used as the outer periphery of the basic frame 10 By arranging the basic frame 10 evenly at a constant angle (every 40 degrees), the basic frame 10 can be floated horizontally above the sea in a balanced manner. That is, a plurality of floats (floating bodies) 12 are equally installed along the basic frame 10 so that the basic frame 10 floats horizontally on the water surface.

  The float 12 is not limited to a resin, and various floats such as a float made of foam polystyrene can be used. However, the floats 12 disposed in the basic frame 10 are of the same type (the same shape and size), and the floats 12 have the same buoyancy.

  An electric winch 13 having a waterproof function fixed between the circular frame 2 and the outer peripheral circular frame 4 is provided at three places at constant angles in the circumferential direction of the outer peripheral circular frame 4, ie, 120 degrees. It is fixed in three places with an angular difference. That is, a plurality of electric winches (wire winding machines) 13 are fixed at a plurality of (three) positions where horizontal balance of the frame 10 can be taken along the basic frame 10.

  These electric winches 13 are fixed to both frames 2 and 4 by fixing fixed bottom plates 13 'between the circular frame 2 and the outer peripheral circular frame 4 at their installation points, and these fixed bottom plates The above-mentioned electric winches 13 are respectively fixed on 13 '.

  These electric winches 13 have an electric motor 14 capable of rotating in forward and reverse directions having a waterproof function, and a wire winding shaft 15 connected to the pulley of the electric motor 14. One end of a wire 16 is connected and fixed, and the other end of the wire 16 is connected and fixed to an anchor 17 installed (fixed) on the seabed 28. The three electric motors 14 have the same characteristics of rotating at the same number of rotations (the same rotation speed), and simultaneously start and stop rotation at the same timing by simultaneously turning on and off.

  The anchor 17 is, for example, a quadrangular pyramid heavy weight obtained by cutting a head made of concrete horizontally, and has a weight capable of being mounted on the sea bed 28 with the large diameter portion facing downward. These anchors 17 are respectively mounted and fixed at three positions on the seabed 28 corresponding to the installation places of the electric winch 13 with an angle difference of 120 degrees along the imaginary circle P concentric with the outer peripheral circular frame 4 It is done.

  A wire fixing ring 18 is fixed to the upper surface of each of the anchors 17, and the wire 16 is connected and fixed between the ring 18 and the wire winding shaft 15. The wire winding shaft 15 is rotated in the forward direction (the electric motor 14 is rotated in the forward direction), so that the wires 16 can be wound by the winding portions 15. The wires 16 are configured to be able to be pulled out of the wire winding portions 15 by rotating the wire winding shafts 15 in the reverse direction (rotation of the electric motor 14 in the reverse direction).

  Each wire winding shaft 15 is provided with a known ratchet mechanism, and when winding the wire 16, the wire winding shaft 15 rotates in the winding direction (forward direction), but in the opposite direction The lock is configured to be locked by the pawl. Therefore, the rotation of the wire winding shaft 15 can be locked by stopping the driving of the electric winch 13 when the wire 16 is wound by a predetermined distance. Further, when the electric winch 13 is driven in the reverse direction, the lock by the pawl of the ratchet mechanism is released, and the wire take-up shaft 15 is rotated in the reverse direction so that the wire 16 can be pulled out.

  The lengths of the three wires 16 between the electric winches 13 and the anchors 17 are the same, and in the non-operating state of the electric winches 13, the buoyancy of the floats 12 causes the wires 16 to expand. Thus, the basic frame 10 is configured to float horizontally on the sea. Then, by simultaneously driving the three electric winches 13 and rotationally driving the electric motors 14 in the same direction (forward direction) at the same rotational speed, the three wires 16 at the same speed. The winding shaft 15 is configured to be simultaneously wound in the same direction. Therefore, the winding amount of the wires 16 of the three electric winches 13 is the same.

  By thus simultaneously winding the three wires 16 in the three electric winches 13, the basic frame 10 is maintained in its horizontal state, against the buoyancy of the float 12, The electric winch 13 can be sunk well in a well-balanced manner.

  In addition, since the buoyancy of the floats 12 constantly and uniformly acts on the basic frame 10 in a submerged state, the wires can be rotated simultaneously by rotating the electric winch 13 at the same speed. At the same time, the basic frame 10 can be floated on the sea by the buoyancy of the floats 12 while maintaining the horizontal state of the basic frame 10 by simultaneously pulling out the wire 16 from the wire winding shafts 15. Therefore, the amount of withdrawal of the wires 16 of the three electric winches 13 is the same.

  Even when the basic frame 10 floats up, the buoyancy of the float 12 always acts equally on the basic frame 10, so the drawn out wires 16 maintain the extended state while maintaining the basic frame 10 in an extended state. It can be floated horizontally with a good balance.

  The drive unit (motor, speed reducer, wire take-up shaft, etc.) of each of the above-mentioned electric winches 13 is completely waterproof and has a waterproof function housed in a salt-proof housing (waterproof case). There is no problem if it sinks into the sea itself. In addition, it is preferable to use a water-soluble non-toxic harmless glycol-based lubricant for the reduction gear of each electric winch 13.

Reference numeral 29 denotes a single-axis inclination sensor horizontally fixed to the housing or circular frame 1 of each of the electric winches 13 (see FIGS. 1 and 13), each housing or circular of the three electric winches 13 described above It is installed in each of the frames 1 (all three). The inclination sensor 29 is fixed in the direction of the center P 'of the circular frame 2 and its rotation axis 29a (see FIG. 13) is provided orthogonal to a straight line L toward the center P' of the circular frame 2. It is done. Therefore, when the circular frame 2 is inclined in the direction of the center P ', that is, when the inclination sensor 29 is inclined in the direction of the center P' (-direction), a negative voltage proportional to the inclination angle is output. 2 is configured to output a positive voltage proportional to the inclination angle when the center P 'is inclined in the opposite direction, that is, when the inclination sensor 29 is inclined in the direction (+ direction) opposite to the center P' There is. The inclination sensor 29 indicates an output voltage of "0" when the horizontal state is maintained.

  Each of these three inclination sensors 13 is connected to the above-mentioned on-board or land control unit 34 by a connection cable 31 (electric cable) (see FIGS. 4 and 7).

  Further, a depth sensor 30 is fixed to one position of the outer peripheral circular frame 4 of the circular frame 2. The depth sensor 30 senses water pressure and outputs a voltage proportional to water depth. The depth sensor 30 is connected to the control unit 34 on the ship or on land via a connection cable 32 (see FIGS. 4 and 7).

  The electric winches 13, the inclination sensors 29 and the depth sensors 30 are connected to the underwater cable (electric cable) 20 by connection cables (electric cables) 19, 31 and 32, and the underwater cable 20 is relayed on the water floating on the sea It is connected to the box 21 (see FIG. 4).

  Then, the water relay box 21 and the control panel 23 of the ship 22 on the sea or the control panel 23 of the land are connected by a connection cable (electric cable) 25, and the generator 24 of the control room 22 ′ on the ship 22 or on land is connected. And the control panel 23 are electrically connected. As a result, the generator 24 of the control room 22 'on the ship 22 or on land is driven, and power is supplied to the connection cable 25, the water relay box 21, the underwater cable 20, the connection cable 19, and the power via the control panel 23. The three electric winches 13, the three inclination sensors 29, and the depth sensor 30 can be supplied via the sensors 31 and 32. The water relay box 21 has a float so as to float in the sea, and has a connector to which the connection cable 25 and the underwater cable 20 can be attached and detached.

  A net for mesh (wire mesh) 26 is attached to the circular frame 2 downward along the entire circumference, and the net 26 is suspended downward from the circular frame 2 in a cylindrical shape. . A similar mesh (wire mesh) 26a is formed on the bottom of the mesh 26 and is closed by the mesh 26a. The upper surface 26b is normally open, but the upper surface 26b can also be closed with a mesh. Is configured as.

  FIG. 6 is a view showing a state in which the floating sink-type ginger according to the present invention is installed on the sea, and in the present embodiment, the electric winch 13 is equally spaced at four positions every 90 degrees of the basic frame 10. The four anchors 17 are provided corresponding to the four electric winches 13 on the seabed 28, and the electric winches 13 and the anchors 13 are connected by four wires 16.

Next, a drive control configuration of each of the electric winches 13 and the like will be described.
FIG. 7 is a block diagram of the control unit 34 according to the present invention, and the control unit 34 is provided in the control panel 23 of the ship 22 or in the control panel 23 of the control room 22 'on land. The three electric motors 14 are connected to the control unit 34 by the connection cable 19 via three drive circuits 33 as drivers corresponding to the electric motors 14, and the three electric motors 14 are provided. The inclination sensor 29 is connected by the connection cable 31, the depth sensor 30 is connected by the connection cable 32, and the operation panel 35 is connected. In the block diagram, the relay box 21 is omitted for convenience (the same applies to FIG. 8).

  The control unit 34 is configured of a programmable controller having a CPU and the like, and controls the electric motor 14 in accordance with an instruction input from the operation panel 35, and performs processing in accordance with the programs shown in FIGS. It is something to execute.

Each drive circuit 33 is provided in a control board 23 adjacent to the control unit 34. Incidentally, the electric motor 14, drive circuit 33, like the inclination sensor 29, for which there are a plurality, if pointing individually are denoted the subscripts of ₁₄ 1, 33 _2.

  The operation panel 35 (see FIG. 8) is provided with a simultaneous drive switch 40 for turning on and off the electric motor 14 simultaneously. The simultaneous drive switch 40 is composed of a forward direction (wire winding) switch (+) and a reverse direction (wire withdrawal) switch (−), both of which drive circuit when the switch is pressed. The three electric motors 14 are simultaneously driven via 33, and when the switch is released, the three electric motors 14 are simultaneously stopped via the drive circuit 33 (see FIG. 9). ).

The above operating panel 35, the electric motor ₁₄ 1-14 ₃ on-off individually separately driven switch ₄₁ 1-41 ₃ are provided. The individual drive switches 41 _{1 to} 41 ₃ turn on and off the respective electric motors 14 _{1 to} 14 ₃ individually, and any one of them is a forward direction (wire winding) switch (+) and a reverse direction (wire pulling out) 2.) It is composed of two switches (-). Both, in pressing the switch, one of the electric motor ₁₄ 1-14 ₃ through the driving circuit _{33 to} 333 corresponds to the switch ₄₁ 1 to 41 ₃ is driven, when released from the switch, the drive circuit The electric motors driven via 33 _{1 to} 33 ₃ are configured to be stopped (see FIG. 10).

  Furthermore, the operation panel 35 is provided with a ten key 42 for specifying the depth, and is configured to be able to arbitrarily set the depth from the water surface when the ginger is sunk from the ten key 42 (see FIG. See Figure 11).

FIG. 8 is a functional block diagram of the control unit 34. The control unit 34 controls the electric motors 14 _{1 to} 14 ₃ through the drive circuits 33 _{1 to} 33 ₃ based on pressing of the simultaneous drive switch 40. At the same time, the electric motors 14 _{1 to} 14 ₃ can be individually driven via the drive circuits 33 _{1 to} 33 ₃ based on the pressing of the individual drive switches 41 _{1 to} 41 ₃ simultaneously and reversely driving, simultaneous on / off means 39 for stopping driving. The corresponding electric motors 14 _{1 to} 14 ₃ are driven forward or reverse based on the inclination signals from the individual on / off means 36 _{1 to} 36 ₃ for each electric motor to drive or stop driving and the inclination sensors 29 _{1 to 2 3 3} Horizontal stop means 37 which keeps the basic frame 10 horizontal by judging whether it is horizontal or not while stopping driving, the depth signal from the depth sensor 30, And a depth control means 38 for making the basic frame 10 (raw) sink or float to the input predetermined depth by comparing the input depth with the input depth. Note that the horizontal stabilizing means 37, when the signal from the inclination sensor 29 _{1-29 3} becomes all "0" (horizontal), and the like to light the horizontal display portion 44 of the operation panel 25, the basic It has a function of displaying to the operator that the frame 10 is horizontal.

  Since the float-sink type ginger according to the present invention is configured as described above, its operation will be described next.

  First, as shown in FIG. 4, the basic frame 10 is floated on the sea surface 27 by the float 12 and the net 26 is suspended in the sea, in three places of the seabed 28 at positions corresponding to the three electric winches 13 Anchors 17 are fixed, wires 16 are respectively connected between the respective anchors 17 and the wire winding shafts 15 of the respective electric winches 13, and the basic frame 10 is made the above-mentioned sea surface 27 with these wires 16 as the same length. It floats on top horizontally.

  The submersible cable 20 connected to each connecting cable 19 of each electric winch 13 and further to the connecting cable 31 of the inclination sensor 29 and the connecting cable 32 of the depth sensor 30 is connected to the on-water relay box 21 via the sea surface 27 or the sea. On the other hand, the connection cable 25 connected to the control panel 23 of the ship 22 is connected to the above-mentioned water relay box 21. In this state, fish (for example, yellowtail, yellowtail, amberjack, etc.) can be cultured in the net 26.

If it is necessary to sink the net 26 into the sea, the forward switch of the simultaneous drive switch 40 of the operation panel 35 of the operation panel 23 may be pressed (see FIG. 9P1). Then, the simultaneous on / off means 39 of the control unit 34 simultaneously drives the electric motors 14 _{1 to} 14 ₃ in the forward direction through the drive circuits 33 _{1 to} 33 ₃ (see FIGS. 9P 2 and P 3). Are driven to rotate simultaneously at the same rotational speed in the positive direction.

  Then, since the wire winding shafts 15 of the three electric winches 13 are simultaneously rotationally driven in the positive direction at the same rotation speed, the winding of the three wires 16 is simultaneously started at the same speed. As a result, the basic frame 10 is wound evenly at the same speed with the wires 16 at three locations (four locations in the embodiment of FIG. 6) which are equal in the circumferential direction in which the electric winch 13 exists. The basic frame 10 sinks into the sea downward against the buoyancy of the floats 12 while maintaining the horizontal state.

Then, for example, as shown in FIG. 5, the pressing operation of the forward switch of the simultaneous drive switch 40 is performed at a position where the upper circular frame 1 of the basic frame 10 is completely sunk from the sea surface 27 to a predetermined depth. It is sufficient to stop it (see FIG. 9P3). Then, the driving of the electric motor ₁₄ 1-14 ₃ is stopped simultaneously, driving of the respective electric winch 13 is stopped at the same time.

  That is, the wire winding shafts 15 of the electric winches 13 are simultaneously stopped (see FIG. 9P4), the wire winding shafts 15 are locked, and the winding of the wires 16 is simultaneously stopped. At this time, since the three wires 16 are wound around the wire winding shaft 15 by the same length, the basic frame 10 remains horizontal even after the wire winding, as shown in FIG. It can be kept submerged as shown in.

  At this time, although the vertical upward buoyancy acts evenly along the entire circumference of the basic frame 10 by the nine floats 12, the wire winding shafts 15 of the respective electric winches 13 stop and Since the rotation is locked, the basic frame 10 remains submerged in the sea shown in FIG. 5 without rising. Further, since the respective electric winches 13 and the respective wires 16 are provided at three positions of the basic frame 10 at every 120 degrees where horizontal balance can be obtained, the reaction force of the vertical downward with respect to the buoyancy against the basic frame 10 It acts equally, so that the basic frame 10 can stay submerged in the sea while maintaining its horizontal position.

  In order to raise the basic frame 10 to the sea from the state where the basic frame 10 sinks into water as shown in FIG. 5, it is sufficient to press the reverse direction switch (-) of the simultaneous drive switch 40 (see FIG. 9P1) ). Then, similarly, while pushing the reverse direction switch, the three electric motors 13 are simultaneously driven in the reverse direction at the same rotation speed, and the wires 16 are simultaneously pulled out from the three electric winches 13 (FIG. 9P1 to FIG. See P3). Since the buoyancy by the float 12 always acts on the basic frame 10 uniformly, the basic frame 10 floats while maintaining the level by the buoyancy of the float 12 when the wire 16 is pulled out.

  Then, when the pressing of the reverse direction switch is released, the three electric motors 14 simultaneously stop (see FIG. 9P4), so that the respective wire winding shafts 15 are locked at the levitation position, and produced at the levitation position. It can be stopped in the horizontal state.

The electric motors 14 _{1 to} 14 ₃ can also be individually driven by the individual drive switches 41 _{1 to} 41 ₃ . For example, in the case where the bottom of the floor is uneven and the position of the anchor 17 is high and low, in order to maintain the level of the basic frame 10, it is necessary to make the lengths of the wires 16 different. For this reason, it is necessary to drive the said electric winch 13 separately.

For example, if only the wire 16 of the electric winch 13 ₁ (electric motor 14 ₁ ) needs to be slightly shortened in order to keep the basic frame 10 horizontal, pressing the forward direction switch of the individual drive switch 41 ₁ Good (see Figure 10P1). Then, for driving the electric motor 14 ₁ in the forward direction corresponding individual on-off means 36 ₁ through the driving circuit 33 ₁ (see FIG 10P2, P3), only the electric winch 13 ₁ of the wire 16 is taken up, the Only the wires 16 can be shortened, which keeps the basic frame 10 horizontal. Incidentally, when the pressing of the forward direction switch is released, the winding operation of the wire 16 is similarly stopped.

Wire may be pressed, by the same operation, the electric winch 13 ₁ - Conversely, when it is necessary to slightly longer only the electric winch 13 ₁ of the wire 16 is reverse switch individual drive switch 41 ₁ () 16 can be extracted (see FIGS. 11P1 to P4).

  As described above, since the electric winches 13 can be driven individually, the basic frame 10 can be maintained horizontal regardless of the topography of the seabed. At this time, the operator of the operation panel 35 can easily confirm that the basic frame 10 has become horizontal since the horizontal display portion 44 of the operation panel 35 is lit and the like. Thus, the simultaneous on / off means 39 and the individual on / off means 36 of the control unit 34 can be operated separately.

  Next, when it is desired to sink the ginger to a predetermined depth, the desired depth may be input from the ten keys 42 of the operation panel 35. Here, in order to sink the basic frame 10 to a position 10 m from the sea surface, "10 m" is input from the ten key 42 (see FIG. 11P1). Then, the depth control means 38 (detection means 38a) of the control unit 34 detects the depth signal from the depth sensor 30, and recognizes the depth of the current basic frame 10. In the case of this embodiment, since the basic frame 10 exists above the sea level (0 m in depth), the depth control means 38 (comparing means 38 b) compares the current depth (0 m) with the input depth (10 m). It is judged that the input depth is deeper than the current depth (FIG. 11P2), and the simultaneous on / off means 39 is instructed to rotate (roll up) the three electric motors 14 in the forward direction (see FIG. 11P3) .

  Then, the simultaneous on / off means 39 simultaneously drives the three electric motors 14 in the positive direction, and as a result, the three electric winches 13 simultaneously wind up the wires 16 (see FIG. 11P3). Therefore, the basic frame 10 sinks in a state of maintaining the horizontal, but the depth control means 38 (detection means 38a) detects the depth signal from the depth sensor 30 (see FIG. 11P5), and the depth The drive of the three electric motors 14 is stopped at the same time as the depth (10 m) at which the X.sub.1 coincides with the input depth (10 m) (see FIGS. 11P6 and P7). Then, the wire winding shaft 15 is simultaneously locked, and when the basic frame 10 reaches a depth of 10 m, it stops while maintaining the horizontal state.

  The depth of ginger can be set to any depth according to the type of fish and shellfish bred in ginger. For example, a position of 10 m from the sea surface, a position of 20 m from the sea surface, a position of 30 m from the sea surface, etc. It is possible.

  In the case of feeding or the like, when it is necessary to surface the ginger, it is sufficient to input, for example, a depth of 3 m from the sea surface from the ten keys 42 (see FIG. 11P1). Then, the depth control means 38 (depth calculation means 38c) compares the current depth (10 m) with the inputted depth "3 m" and judges that 7 m should be levitated to set the depth "3 m". The simultaneous on / off means 39 is instructed to rotate the three electric motors 14 in the reverse direction (-) (see FIG. 11P4).

  Then, the simultaneous on-off means 39 simultaneously drives the three electric motors 14 in opposite directions, and as a result, the three electric winches 13 draw the wires 16 simultaneously (see FIG. 11P4). Therefore, although the basic frame 10 floats up in a state of maintaining the horizontal, the depth control means 38 (the inspection means 38a) detects the depth signal from the depth sensor 30 (see FIG. 11P5), and the depth The drive of the three electric motors 14 is stopped at the same time when the depth D (d) coincides with the input depth (3 m) (see FIGS. 11P6 and P7). Then, the wire winding shaft 15 is simultaneously locked, and when the basic frame 10 reaches a depth of 3 m, it stops while maintaining the horizontal state. Thus, the production can be set to a predetermined depth simply by inputting the desired depth from the ten key 42.

Next, the operation of the ginger automatically maintaining the level will be described.
The horizontal maintenance means 37 of the control unit 34 receives inclination signals from the _three inclination sensors 29 _{1 to 2 3 3} , and each of the electric motors 14 _{1 to} 14 ₃ is individually selected according to plus or minus of each inclination signal. Drive control (see Figure 12).

For example operation of the horizontal stabilizing means 37, when the inclination signal from the inclination sensor 29 ₁ is, for example, negative (slope of the center P 'side) will detect it (see FIG 12P1, P2), the corresponding electric motor 14 ₁ is rotationally driven in the forward direction, and only the wire 16 is wound (FIG. 12P3). Further, when the inclination signal from the inclination sensor 29 _1, for example, positive (inclined to the side opposite to the center P ') will detect it (Fig 12P1), the rotation of the corresponding electric motor 14 ₁ in the opposite direction driving Then, only the wire 16 is pulled out (see FIG. 12P4).

Thereafter, the horizontal stabilizing means 37 detects whether or not the signal from the inclination sensor 29 ₁ becomes "0" during the horizontal, unless set to "0", repeating the same operation returns to Step P1 (See FIGS. 12P1 to P4 and P13). If the signal from the inclination sensor 29 ₁ and the other tilt sensors ₂₉ 2, 29 ₃ becomes all "0", after displaying the horizontal display unit 44 (FIG 12P14), whether to end the process A determination is made (FIG. 12P15), and if the process has not ended, the process returns to step P1 and the same operation is repeated again.

Note that the horizontal stabilizing means 37, the inclination sensor 29 _2, the signal from the tilt sensor 29 ₃ is also received, respectively, by the inclined vibration or negative or positive as well, the electric winch ₁₃ 2, 13 ₃ of the winding Alternatively, it is pulled out (see FIGS. 12P5 to P8, see P9 to P12 in FIG. 12), and finally it is detected whether it is horizontal or not (see FIG. 12P13), and the same operation is repeated until the processing is finally finished. Thus, the horizontal stabilizing means 37 the inclination sensor 29 _1-29 "0" output voltage in all sensor ₃ next, when it is determined that the horizontal in all of the sensors are horizontal to the horizontal display unit 44 The display of the effect, for example, the lighting of the horizontal display unit 44 is performed.

By the horizontal maintenance operation, always has detected a signal from the inclination sensor 29 _{1-29 3,} based on the inclination signal, by the electric motors for forward and reverse drive, the winding of three wires 16 And by constantly pulling out, the level of the basic frame 10 can be maintained. Therefore, although the basic frame 10 is constantly tilted and oscillated in any direction under the influence of waves, wind, etc., the above-mentioned swing is performed by performing the horizontal attitude control. (Swaying) can be minimized and the horizontal attitude of the ginger can be maintained.

  The horizontal attitude control (control in FIG. 12) may be performed only when the horizontal attitude control switch 45 is provided on the operation panel 35 and the switch 45 is turned on.

Further, as a method of rearing fish and shellfish using the floating and sinking ginger according to the present invention, the depth suitable for the type of fish and shellfish (for example, yellowtail, yellowtail, etc.) to be reared is inputted from the ten keys 42. Then the control unit 34 (the depth control means 38), based on the input depth, simultaneous on-off means 39 each wire winder (three, the electric motor 14 _{1-14 3)} simultaneously driven, the The basic frame 10 can be sunk or floated to a predetermined depth, and the ginger can be maintained at the depth suitable for the fish and shellfish.

  With this configuration, for example, when rearing (including aquaculture) fish in ginger on the sea, it is possible to easily sink or float the ginger to an optimum depth according to the type of fish and shellfish.

  Further, as a method of rearing fish and shellfish using the floating and sinking type ginger according to the present invention, an introduction pipe (for example, flexible hose 46, see FIG. 6) reaching the inside of the ginger from a ship or land on water is provided The fish and shellfish in the ginger can be sprinkled with food through 46.

  With this configuration, even if the ginger is in deep water, for example, the flexible hose 46 can feed bait to the inside of the ginger, and the fish and shellfish can be efficiently reared without wasting the bait. can do.

  In the present invention, as described above, by sinking the floating and sinking ginger in the sea, the ginger can be maintained at the water level (any depth) of the appropriate temperature of the fish and shellfish, and aquaculture can be performed under appropriate conditions. it can.

  In addition, it is possible to sink the ginger into the sea temporarily for only a short time temporarily at the time of a typhoon, a stormy weather, or the like when the weather is severe.

  In addition, fish and shellfish can be bred (including aquaculture) in the state of being sunk into the sea, which is less affected by waves and winds, so the waves and winds that have been considered unsuitable in the past (offshore etc. Breeding etc. can be made possible.

  In addition, by sinking ginger to about 3 m or less from the sea surface, it is possible to reduce the generation of aura, algae and the like adhering to the net.

  Furthermore, even if a spill accident such as heavy oil or red tide etc. occurs (on the surface of the sea), the damage caused by the heavy oil etc. can be reduced by maintaining the state where ginger is sunk in the sea.

  Further, since the floating and sinking ginger according to the present invention can be electrically controlled on board or on land, a plurality of the floating sinking ginger according to the present invention is installed on the sea, and the plurality of floating sinks are concentrated on the ship or on land. You can control the ups and downs.

  What is shown in FIG. 14 and FIG. 15 is another embodiment of the floating and sinking ginger according to the present invention. This floating and sinking ginger is used for cultivating shellfish such as oyster 43 and the like. The float-sink type ginger has the same basic structure as that of the above embodiment, so the corresponding parts are denoted by the same reference numerals. The difference from the above embodiment is that the basic frame 10 is a square, and only one electric winch 13 is provided at the central portion (center of gravity) of the basic frame (square frame) 10, and the electric winch Only one anchor 17 is provided on the seabed corresponding to 13, and the one anchor 17 and the one electric winch 13 are connected by one wire 16.

  In addition, the oysters 43 to be cultured have a plurality of strings (linear shellfish culture linear bodies) 47 hanging down along the outer peripheral square frame 4 and grow oysters along the strings 47.

  Further, a plurality of support frames 48 are arranged and fixed in parallel inside the outer peripheral rectangular frame 4 of the basic frame 10, and a fixed bottom plate 13 'is fixed between a pair of support frames 48, 48 at the center. The electric winch 13 is fixed on the fixed bottom plate 13 ′, and the wire 16 is suspended downward from the opening 13 ′ ′ provided in the fixed bottom plate 13 ′. It is a support frame of bottom plate 13 '.

  The drive control configuration of the electric winch 13 is the same as that of the above embodiment, and the electric winch from the control panel 23 of the control room on the ship 22 or on the land via the connection cable 25, the water relay box 21, the underwater cable 20 and the like. 13 are connected to the generator 24. Then, the control stop of the electric winch 13 is controlled by the operation panel 23.

  Also in the floating and sinking ginger of this embodiment, by driving the electric winch 13 forward and reversely, the ginger can be submerged in the sea, and the same effect as that of the above embodiment can be obtained. At this time, since the electric winch 13 is located at the center of gravity of the basic frame 10, when it sinks, the basic frame 10 can sink in a balanced manner while maintaining the horizontal state against the buoyancy of the float 12. By rotating the electric winch 13 in the reverse direction, it is possible to levitate in a balanced manner by the buoyancy of the float 12 while maintaining the horizontal state of the basic frame 10. Alternatively, the depth sensor 30 may be installed and configured to sink or rise to a predetermined depth, as in the embodiment of FIG.

  Further, according to this embodiment, since only one each of the electric winch 13, the wire 16 and the anchor 17 is sufficient, the floating structure can be realized with a simple structure and with less electric power.

  In the embodiment of FIG. 2, the net 26 may be replaced by a linear member (string) 47 for shellfish culture, or in the embodiment of FIG. 9, a cylindrical net 26 may be used instead of the string 47. good.

  As described above, the present invention simultaneously drives the plurality of wire winders 13 via the plurality of forward and reverse drive motors 14 simply by turning on or off the simultaneous drive switch 40 to perform the wire winding operation or the drawing operation. Can be performed simultaneously, and the floatation and sinking operation of the ginger in the state of maintaining the horizontal posture can be performed by an extremely simple operation.

  In addition, by driving the forward and reverse drive motor 14, only the specific wire winding machine 13 can be wound up or pulled out. For example, the water bottom is not horizontal, and it is specified to make the production horizontal. Even if the length of the wire 16 needs to be shortened or lengthened, the ginger can be placed horizontally without any problem.

  Also, by keeping the horizontal maintaining means 37 in the operating state at all times, the horizontal attitude of the basic frame 10 can be maintained at all times, and the swinging of the basic frame 10 due to the influence of waves or wind can be minimized.

  Further, for example, the ginger can be sunk or floated to a predetermined depth simply by inputting from the depth input unit 42 a depth suitable for fish and shellfish reared in ginger.

  In addition, for example, when rearing fish and shellfish in the sea on the sea, it is possible to easily sink or float the ginger to an optimum depth corresponding to the type of fish and shellfish.

  Moreover, even if ginger is in deep water, for example, it is possible to feed bait to the inside of ginger by the introduction tube, and fish and shellfish can be reared efficiently without wasting bait.

  According to the floating and sinking ginger according to the present invention, since it can be installed without being influenced by the weather, the temperature of the seawater, the ocean current, etc., the floating and sinking ginger can be installed in an optimum environment for fish and shellfish to be cultured. is there.
