Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a free floating state in which a fry, a larvae and an aquatic larva are enclosed in a cage-like body surrounded by a mesh partition wall, and is immersed in seawater. A cultivation device for marine aquatic organisms that moor and grow under the sea surface while growing and harvesting by adjusting and maintaining the breeding environment at a desired water depth by mooring seagrass algae in the skeleton and growing under the sea surface. Things.

[Prior art] As a conventional aquaculture means, it is common to simply release fry or larvae into seawater adapted to the natural state, or to scatter them and wait for their growth to catch them. Is extremely low, and the labor is high together with the cost, and the economy is poor.

In addition, in the case of performing aquaculture by perforating the end of the juvenile shell with an electric cone every one and inserting and locking the cord and connecting it to the seawater,
Since they cannot be freely exercised because they are connected to each other, they cannot grow sufficiently.

Therefore, facilities such as pool pools suitable for inhabiting are provided, and enormous costs are applied to the pools or seawater pools of partition type which are well-suited to the terrain and separated into seawater pools such as abalone or sea urchin. Some fish are released from young animals.

[Problems to be Solved by the Invention] By the way, even in the above-mentioned partition type, unlike the natural state, the seawater must be circulated by mechanical force to constantly clean the environment, and abalone in such a culture facility For aquaculture, etc., algae such as Wakame (wakame) grow as feeders, so this chop is chopped and given, so fresh Wafu is always required, and its storage is difficult. Considerable effort is needed to remove the remaining Japanese fabric to keep it from becoming spoiled and to keep the stored water clean at all times. In addition, there is a problem that even during the growth process, the cost of maintenance and management is considerably increased due to the contamination due to the death and the decay.

The present invention has been made in view of the above-described problems, and has as its object to freely move in a cage-shaped body in which a fry, a larva and an aquatic larva are surrounded by a mesh partition wall. Enclosed in a state, moored in seawater to allow seagrass algae to thrive in the building and submerge and float below the sea surface, and grow and harvest at the desired water depth while adjusting and maintaining the growing environment. It is an object of the present invention to provide a marine aquaculture apparatus which is easy to obtain and manage.

Means for Solving the Problems In order to achieve the above object, the marine aquaculture apparatus of the present invention comprises a lower hollow box 1 having a hollow chamber 1a and a locking portion 4 interposed between the lower hollow box 1 and a main pillar 2. A cap body 8 is fixed, the cap body 8 and the barrier net 7 cover the entire peripheral wall to form a frame, and a holding box frame 9 having a hollow chamber 9b between the main columns 2 is provided. The movable protrusion 14 is protruded from the bottom surface of the holding box frame 9, and the lower hollow box 1 is attached to the side of the holding box frame 9 by the movable protrusion 14.
A ring shaft 20 interlocking with the movable projection 14 is provided by superimposing, so that the rope 11 inserted through the ring shaft 20 is tightly clamped and clamped together with the tie 10, and the storage pressure tank placed on the sea surface e The lower hollow box 1 is connected to the three-way switching valve 23 in the
The hollow chamber 1a is connected to the hollow chamber 9b of the holding box frame 9, and the lower hollow box 1 and the holding box frame 9 are provided with a suction / drain valve 26, respectively.

[Operation] While the culture device is floating on the sea surface e, the gas from the storage tank 22 fills the hollow chamber 1a of the lower hollow box 1 and the hollow chamber 9b of the holding box frame 9, and the lower hollow box The body 1 and the holding box frame 9 are in a superposed state, the lower hollow box 1 is located on the sea surface e, and the frame is in a state of protruding above seawater. Then, using the holding box frame 9 as a scaffold, preparation for aquaculture is prepared in the skeleton.

When the preparation for aquaculture is completed, the hollow chamber of the lower hollow box 1
The gas in 1a replaces seawater and increases the weight of the lower hollow box 1.

When the weight of the lower hollow box 1 exceeds the buoyancy due to the increase in the weight of the lower hollow box 1, the lower hollow box 1 is slightly settled down together with the frame, and the polymerization of the lower hollow box 1 and the holding box frame 9 is released. The movable projection 14 causes the distal end of the ring mounting shaft 20 to protrude further from the side surface of the holding box frame 9, thereby releasing the bent and clamped state of the rope 11. As a result, the holding box frame 9 is connected to the rope 11
It becomes movable with respect to.

Then, the holding box frame 9 floating on the sea surface abuts on the locking portion 4 of the cap crown 8 due to the sinking of the lower hollow box 1 with the frame, and thereafter the lower hollow box with the frame. Settles in the sea with 1.

When the device reaches near the desired depth, the holding box frame 9
The gas in the hollow chamber 9b is released to the atmosphere. Due to the release of the gas, seawater flows into the hollow chamber 9b and increases the weight of the holding box frame 9.

Due to the increase in the weight of the holding box frame 9, the holding box frame 9 approaches the lower hollow box 1 while being guided by the main pillar 2, and finally the lower hollow box 1 and the holding box frame. 9 becomes a polymerization state.

In this superposed state, the movable projection 14 is accommodated in the bottom surface of the holding box frame 9, and the tip of the mounting shaft 20 is drawn toward the side of the holding box frame 9, and is disposed on the side of the holding box frame 9. The rope 11 is bent and clamped to the provided fastening member 10. As a result, the entire apparatus is stopped by the rope 11 at a desired depth. Then, desired aquaculture is performed in this state.

When the apparatus needs to be floated, first, gas is supplied into the hollow chamber 9b of the holding box frame 9. Since the seawater in the hollow chamber 9b is pressurized by the supply of the gas, the seawater in the hollow chamber 9b is replaced with the gas by the action of the suction / drain valve 26 screwed into the hollow chamber 9b, and the hollow chamber 9b The interior will be filled with gas. Therefore, the holding box frame 9 is reduced in weight and is in a floating state.

By the way, since the holding box frame 9 is in a state of being overlapped with the lower hollow box 1, it is in a tightly clamped state with the rope 11 as described above. Therefore, the three-way switching valve 23 in the accumulator 22 is temporarily switched to the discharge pipe g to discharge the residual gas in the hollow chamber 1a of the lower hollow box 1 to the outside and additionally introduce seawater to the lower hollow box. The lower hollow box 1 is slightly settled by increasing the weight of the first hollow box 1 once, and the polymerization of the lower hollow box 1 and the holding box frame 9 is removed. As a result, the holding box frame 9 is released in the tightly clamped state with the rope 11, so that the holding box frame 9 rises in the seawater and comes into contact with the locking portion 4 of the cap crown 8.

Next, gas is also supplied into the hollow chamber 1a of the lower hollow box 1. Thereby, the seawater in the hollow chamber 1a is also replaced with the gas, and the hollow chamber 1a is also filled with the gas. Therefore, the weight of the lower hollow box 1 is also reduced, and the entire apparatus floats toward the sea surface.

Then, when reaching the sea surface, the holding box frame 9 stays partially floating above the water surface, the frame further rises and projects into the atmosphere, and finally the holding box frame 9 and the lower hollow box 1 are superposed, and the rope 11 is brought into the tightened and clamped state as described above.

It is screwed on the screw. A flow hole is formed in the valve jacket of the suction / drain valve 26, and an outer valve is disposed in the valve jacket. The outer valve is stretched between the outer valve spring presser and the outer valve. The outer valve spring is biased toward an inclined outer valve seat formed inside the valve jacket. An adjusting screw which penetrates through the outer cover from the outer valve spring retainer is screwed to the protruding crown so as to adjust the urging force of the outer valve spring. The outer valve has an outer valve cavity communicating with the water suction hole, and a mushroom-shaped valve is disposed in the outer valve cavity, and the mushroom-shaped valve is attached to a mushroom valve spring retainer. The mushroom valve spring is biased so as to be in close contact with the inner valve seat formed on the outer valve. Further, the mushroom valve spring presser screw screwed onto the mushroom valve is advanced and retracted by a screw piece to adjust the urging force of the mushroom valve spring.

Further, on the sea surface e, a storage tank 22 as shown in FIG. The animal pressure tank
A sealed operation chamber b is formed in the storage chamber 22 and partitioned from the pressure storage chamber a. Two three-way switching valves 23 are disposed in the operation chamber b. Each of the three-way switching valves 23 is connected to a storage chamber a, a discharge pipe g, and a hose connected to the hollow chamber 9b and the hollow chamber 1a by a pressure supply pipe c via an air supply stop valve d.
24 is selectively communicated with a communication pipe f penetrating the pressure storage chamber a to which it is connected. The supply pipe j is an on-off valve i
Is connected to the connection pipe h to the pressure storage chamber a via the pressure storage chamber a, and is used for replenishment of the pressure gas to the pressure storage chamber a. Reference numeral 25 denotes a ring fitting for collecting and holding the plurality of suspension ropes 11 and the two hoses 24.

In the culture device having the above-described configuration, while the culture device is floating on the sea surface e, the gas introduced from the storage tank 22 via each hose 24 is filled in the hollow chamber 9b and the hollow chamber 1a. Due to these buoyancy, the lower hollow box 1 and the holding box frame 9 are superimposed, the lower hollow box 1 is positioned on the sea surface e, and the frame is protruding above the sea. Then, using the holding box frame 9 as a scaffold, preparation for aquaculture is prepared in the skeleton.

When the preparation for aquaculture is completed, the other end of the hose 24 connected to the hollow chamber 1a is switched to the discharge pipe g by the three-way switching valve 23 in the storage tank 22, and the gas in the hollow chamber 1a is discharged to the discharge pipe g. Release to the atmosphere from. Since the pressure in the hollow chamber 1a is reduced by the release of the gas, the suction / drain valve 26 screwed into the hollow chamber 1a operates,
The mushroom-shaped valve is pushed out into the hollow chamber 1a by the mushroom valve spring and is separated from the inner valve seat, so that seawater flows from the flow hole of the valve jacket to the water absorption hole, the outer valve cavity, and the mushroom-shaped valve. To flow into the hollow chamber 1a to increase the weight of the lower hollow box 1.

When the weight of the lower hollow box 1 overcomes the buoyancy due to the increase in weight, the lower hollow box 1 is slightly settled down together with the frame, and the polymerization of the lower hollow box 1 and the holding box frame 9 is released. The movable projection 14 provided in the binding operation chamber 13 penetrates through the bottom surface of the holding box frame 9 and protrudes therefrom, and holds the tip of the ring mounting shaft 20 via the retaining rod 18 and the pivot 19 to hold the holding box frame 9. From the side surface of the rope 11 to release the bent and clamped state of the rope 11. Thereby, the holding box frame 9 becomes movable with respect to the rope 11.

Then, the holding box frame 9 floating on the sea surface is successively provided with the locking portions 4 of the cap crown 8 by the settling of the lower hollow box 1 with the frame.
And finally comes into contact with the locking portion 4 and thereafter sinks into the sea in the state shown in FIG. 2 together with the lower hollow box 1 with the frame. During the sedimentation, since the upward force acts on the upper part of the frame by the buoyancy applied to the holding box frame 9, the entire apparatus descends while maintaining the equilibrium state.

When the device reaches near the desired depth, the holding box frame 9
The other end of the hose 24 connected to the hollow chamber 9b
The gas in the hollow chamber 9b is discharged from the discharge pipe g to the atmosphere by switching to the discharge pipe g by the three-way switching valve 23 in the inside. Since the inside of the hollow chamber 9b is depressurized by the release of the gas, the suction / drain valve 26 screwed to the hollow chamber 9b is operated, and the hollow chamber 9b is operated similarly to the hollow chamber 1a.
The seawater flows into the inside, and the weight of the holding box frame 9 is increased.

Due to the increase in the weight of the holding box frame 9, the holding box frame 9 approaches the lower hollow box 1 while being guided by the main pillar 2, and finally the lower hollow box 1 and the holding box frame. 9 becomes a polymerization state.

In this overlapping state, the movable projection 14 provided in the working chamber 13
Fits inside the bottom surface of the holding box frame 9, and pulls the tip of the ring mounting shaft 20 toward the side surface of the holding box frame 9 via the retaining rod 18 and the pivot 19, and The rope 11 is bent and clamped with respect to the provided tie 10. As a result, the entire apparatus is stopped by the rope 11 at a desired depth. Then, in this state (see FIGS. 1 and 3), desired aquaculture is performed.

If the desired culture has been completed or the device needs to be lifted for other reasons, the hollow chamber 9b of the holding box frame 9 must first be
The other end of the hose 24 connected to the pressure storage tank 22 is switched to the pressure supply pipe c by the three-way switching valve 23 in the pressure storage tank 22, and the pressure storage chamber a of the pressure storage tank 22 is hollowed out through the pressure supply pipe c and the hose 24. The gas is supplied into the chamber 9b. Since the supply of this gas pressurizes the seawater in the hollow chamber 9b, the suction / drain valve 26 screwed into the hollow chamber 9b operates,
The mushroom-shaped valve sticks against the inner valve seat yo against the urging force of the mushroom valve spring. Further, when the pressure of the seawater in the hollow chamber 9b increases, the pressure pushes the outer valve together with the mushroom-shaped valve against the urging force of the outer valve spring, and the outer valve separates from the outer valve seat. The seawater in the hollow chamber 9b passes through the gap from the circulation hole e to the outer valve seat and is discharged from the circulation hole into the external seawater, and the seawater in the hollow chamber 9b replaces the gas supplied sequentially, and the hollow chamber 9b will be filled with gas. Therefore, the holding box frame 9 is reduced in weight and is in a floating state.

By the way, since the holding box frame 9 is in a state of being overlapped with the lower hollow box 1, it is in a tightly clamped state with the rope 11 as described above. Therefore, the other end of the hose 24 connected to the hollow chamber 1a is temporarily switched to the discharge pipe g by the three-way switching valve 23 in the accumulator 22 to discharge the residual gas in the hollow chamber 1a to the outside and add seawater. The lower hollow box 1 is slightly settled by increasing the weight of the lower hollow box 1 by introducing the lower hollow box 1 and the holding box frame 9.
The polymerization with is removed. Thereby, the rope 11 of the holding box frame 9 is
As a result, the holding box frame 9 rises in the sea and comes into contact with the locking portion 4 of the cap crown 8.

Next, the other end of the hose 24 connected to the hollow chamber 1a is switched to the pressure supply pipe c by the three-way switching valve 23 in the pressure storage tank 22, and the pressure in the pressure storage tank 22 is increased through the pressure supply pipe c and the hose 24. From pressure chamber a to hollow chamber
Gas is also supplied in 1a. As a result, the seawater in the hollow chamber 1a also replaces the gas supplied sequentially, and the hollow chamber 1a
1a is also filled with gas. Therefore, the weight of the lower hollow box 1 is also reduced, and the entire apparatus floats in a state as shown in FIG.

Then, when reaching the sea surface e, the holding box frame 9 stays partially floating above the sea surface, and the frame further rises and projects into the atmosphere, and finally the holding box frame 9 and the lower hollow box Body 1
Are superimposed, and the rope 11 is brought into the tightly clamped state as described above.

In the above embodiment, abalone cultivation has been described, but the present invention can also be applied to aquaculture of aquatic organisms such as sea urchins and larvae of fish.

FIG. 7 shows a modification of the above embodiment, in which the lower hollow box 1
And a square pyramid-shaped pyramid-shaped hollow box 29 is used as the cap crown 8, and there is no particular difference in its operation, so that the description is omitted. In addition, 2f is a hollow main pillar, 24d is a collective band of the rope 11 and the hose 24, 28 is a partition bottom plate, 30 is a joining flange, 31 is a support beam, 32 is a collective locking ring, and 33 is a through hole. Things.
