Description

  The present invention relates to a warehouse used by being submerged in the sea.

In the sea, there is little fluctuation in water temperature and an environment suitable for storing goods at a constant temperature is obtained, and because people cannot easily approach it, it is an extremely safe place for crime prevention. Not used.
The reason for this is that a structure that has a strength not to be crushed by a large water pressure is sealed in such a way that seawater does not enter the surroundings in order to secure a use space in the sea, in order to secure a use space in the sea. Although it is necessary to manufacture it in the sea, it is very difficult to manufacture it, and when using the structure, the surroundings are surrounded by seawater, so it is very difficult to put in and out articles such as stored products. It will be difficult.

Under such circumstances, for example, the following Patent Document 1 proposes a concept of constructing a continental shelf city on the sea floor, but its scale is huge, Enclosing with a structure that can withstand high water pressure requires enormous costs and long-term construction work, which is not a realistic proposal.
On the other hand, although the following patent document 2 proposes to provide a food storage facility for rice on the seabed, actual installation is difficult because construction on the seabed is necessary. In addition, the facility is used to carry in and out of the luggage by providing a passage with a moderate downward slope from the coast to the seabed, so that the installation location is limited to the vicinity of the coast and on the land near the coast. However, since it is necessary to secure the site and install related facilities, implementation will be subject to many restrictions in addition to technical aspects, such as human licenses. In addition, the use of the equipment is inefficient because materials cannot be directly taken in or out of the storage ship.

JP-A-6-221003 JP-A-8-225122

The proposals in each of the above patent documents are generated in a wide facility space because all facilities are installed so as to surround a certain space on the seabed, so that waterproof measures to prevent the ingress of seawater, water pressure measures to withstand high water pressure, and so on. Difficult measures such as buoyancy measures to prevent the buoyancy from being lifted against huge buoyancy are necessary, but an effective structure for that is not shown, and in addition, loading and unloading cargo from a carrier ship in the sea The structure is not suitable for going and using as a warehouse.
Therefore, although the present invention has no personal property and can be used freely, unlike the land, it is surrounded by seawater and is always surrounded by seawater and has a huge water pressure, buoyancy, etc. An object of the present invention is to provide an underwater warehouse capable of securing a large space in which stored items can be stored and in which the stored items such as grains can be easily taken in and out.

  In order to solve the above-described problems, the undersea warehouse of the present invention is capable of anchoring a horizontal cylindrical outer shell that can be levitated by the buoyancy of the internal space in the sea against a buoyancy with a mooring material fixed to the seabed. A) a storage room for storing stored items above the internal space, and a buoyancy adjustment room for adjusting buoyancy by exchanging seawater and air below the internal space And on the outer peripheral surface facing the storage chamber, a carry-in part for carrying in the stored goods and a carry-out part for carrying out the stored goods are arranged, and b) both ends of the outer shell and the mooring A water depth adjusting mechanism for adjusting the water depth position by changing the mooring width of the mooring material, and c) the mooring materials at the lower part of the both water depth adjusting mechanisms of the outer shell. Arrange sliders that can be reciprocated up and down and move both sliders in the circumferential direction of the outer shell. D) The buoyancy control chamber is provided with an outer periphery moving mechanism, and the indoor air is introduced into and removed from the air vent provided in the lower part of the room while the air in the room is taken in and out through a vent pipe opened to the sea from the air vent provided in the upper part of the room. A buoyancy control mechanism for inhaling and discharging seawater is provided.

  According to a second aspect of the present invention, in the above invention, the buoyancy control mechanism is provided with an air pump in the ventilation pipe and an electromagnetic valve that enables water absorption and drainage in the water passage, The buoyancy can be controlled by taking in and discharging the seawater in the buoyancy control chamber by opening and closing the electromagnetic valve from the water flow port while simultaneously taking in and out air in the buoyancy control chamber.

  According to a third aspect of the present invention, in the above invention, the water depth adjusting mechanism includes a winding drum that winds the mooring material by rotation of a motor provided in the outer shell, and the mooring material is rotated by forward and reverse rotation of the winding drum. The mooring width of the mooring material can be changed by winding and feeding.

  According to a fourth aspect of the present invention, in the above invention, the outer peripheral movement mechanism is provided with a track on which the slider moves around the outer shell body so that the slider can move along the track. It is possible to move through a wire.

  According to a fifth aspect of the present invention, in the above invention, the space of the buoyancy control chamber is divided into a plurality of portions, and dividing walls are provided to make each space airtight independently.

  A sixth aspect of the present invention is the airtight buoyancy maintenance chamber having a volume capable of ensuring the buoyancy that allows the outer shell body to float even when the buoyancy control chamber is full of seawater at both ends of the outer shell body. It is provided.

  A seventh aspect of the present invention is characterized in that, in the above-mentioned invention, a driving device such as a motor, a power source device such as a battery, a control panel, and wiring-related members are arranged in the buoyancy maintenance chamber.

  The invention according to claim 8 is characterized in that, in the above invention, an inclined guiding surface is provided on the floor surface so that the stored material flows by its own weight toward the carry-out portion.

The subsea warehouse according to the present invention is not a structure that is fixed and constructed on the sea floor, but has the above-described structure, so that the outer body is moored in the sea against the buoyancy by the mooring material fixed on the sea floor and installed in a floating state. Various stored items can be stored and stored in a storage chamber provided in the body.
And since the outer shell is cylindrical, it can withstand a large water pressure, so that the mooring material can be installed deep in the sea if the depth can be fixed to the seabed, and the mooring material can be separated from the seabed by a crane ship or the like. The installation location can be freely selected by lifting and moving.
The outer body can be moved up and down in the sea by the water depth adjusting mechanism. For this reason, the position where the optimum water temperature can be obtained is freely selected from the different water temperatures depending on the water depth in the sea so that the freshness of stored items such as grains can be maintained even if there is no air conditioning system. It can be stored.

  As for manufacturing, it is possible to assemble the whole equipment such as the outer body and floor surface at the onshore factory, and at that time, the environment is not in seawater but in the air on the ground, so the steel plates are joined by welding etc. Work etc. can be performed easily. For this reason, it becomes possible to easily obtain a strong structure that does not cause air leakage or water leakage in the sea and does not break even at high water pressure.

In the sea, the horizontal direction in the center direction of the cylindrical outer body is maintained by adjusting the length of the anchoring material connected to both sides of the outer body.
Further, when the slider moves along the outer periphery of the cylindrical outer shell by the rotation of the outer shell in the circumferential direction by the outer peripheral moving mechanism, the slider is held by the anchoring material gripped so as to be able to protrude and retract on the slider. Is always pulled down to the lowermost part of the outer shell, but this reaction causes the outer shell to rotate in the circumferential direction.
Therefore, by rotating the outer shell body in the circumferential direction by the outer peripheral movement mechanism, it is possible to maintain the horizontal direction of the outer shell body in the circumferential direction. By adjusting the outer shell body in the center direction and the circumferential direction in this manner, the floor surface of the storage chamber can be kept horizontal.
At the same time, the buoyancy control mechanism removes the air in the buoyancy control chamber below the outer body to reduce the buoyancy, thereby ensuring a reliable horizontal surface of the floor of the storage chamber containing the stored item on the upper side of the outer body. Stability can be maintained.
As a result, the water depth adjustment mechanism allows the outer body to be submerged deeply in the sea and stored in a stationary state for a long period of time in a storage room with a flat floor surface. At the same time, since the pulling force for pulling up the anchoring material is reduced by reducing the buoyancy in the buoyancy adjusting chamber, the load on the permanent anchoring material is alleviated and the life of the anchoring material can be extended.

  With regard to loading and unloading of stored items from the carry-in part and the carry-out part of the storage chamber, the water depth adjustment mechanism floats from the sea to the sea surface, the outer shell moves in the circumferential direction by the outer peripheral movement mechanism, and the buoyancy control. By adjusting the buoyancy of the outer shell body by the buoyancy adjustment chamber by the mechanism, it is possible to easily carry in / out work at sea.

  According to a second aspect of the present invention, the buoyancy control mechanism exchanges seawater and air in the buoyancy control chamber while constantly taking air in and out from the opening through the ventilation pipe to the sea that is always open to the atmosphere on the sea surface. It is possible to control the buoyancy of the outer shell floating in the sea by controlling the weight of the whole device and the weight of the storage in the storage chamber, the amount of air in the storage chamber and the amount of air in the buoyancy control chamber It becomes.

  According to a third aspect of the present invention, the winding drum is rotated in the forward and reverse directions by rotation of the motor of the water depth adjusting mechanism, and the mooring material is moored by winding and feeding the mooring material with the winding drum. It becomes possible to determine the depth position in the sea by changing the width.

According to a fourth aspect of the present invention, there is provided a track for moving the slider around the outer shell so that the slider can move along the track, and the slider is driven by a motor via a chain or a wire. Thus, the slider holding the anchoring material can stably move around the outer shell.
When the slider moves, the slider is always pulled down to the lowermost part of the outer shell by the mooring material tensioned by the buoyancy of the outer shell, thereby rotating the outer shell. Then, the floor surface is inclined by the rotation of the outer shell body. By this inclination of the floor surface, when it floats on the sea surface, it becomes easy to put in and out the stored items from the storage room floated on the sea surface.
Further, since the rotation allows the outer shell body to be exposed from the entire sea surface, the maintenance of the outer shell body at sea can be easily performed.

  In the invention of claim 5, the buoyancy control chamber is provided with a dividing wall for dividing the indoor space into a plurality of spaces, and the individual spaces partitioned by the dividing wall are each airtightly independent, whereby the amount of air in each space It is possible to assist the inclination of the outer shell body in the lateral direction by changing. Also, even if one of the independent spaces leaks due to an accident or the like, it can be lifted by the buoyancy of the other space.

  According to a sixth aspect of the present invention, an airtight buoyancy maintenance chamber having a volume capable of securing a buoyancy that allows the outer shell to float even when seawater is full in the buoyancy control chamber is provided at both ends of the outer shell. Thus, a certain amount of buoyancy that allows levitation can always be ensured by the capacity of the buoyancy maintenance chamber, and the risk that the buoyancy adjustment chamber or storage chamber sinks to the seabed even if a water leakage accident occurs can be avoided.

  In the invention of claim 7, various electric-related members used such as a driving device such as a motor, a power supply device such as a battery, a control panel, and wiring are arranged in the buoyancy maintenance chamber. Drive parts are isolated from the buoyancy control room and storage room, as well as from outside seawater, thus avoiding contact with seawater in the indoor air, preventing damage due to saltwater, and for maintenance such as repairs and inspections. It becomes possible to reduce the running cost.

  In the invention of claim 8, it is possible to allow the stored items to flow down on the floor surface by its own weight without using an unloading device such as a belt conveyor from the floor surface toward the unloading portion by the inclined guide surface. It becomes. And a stored thing can be discharged | emitted out of a storage room without a stagnation from the said carrying-out part, and a loading operation becomes easy.

It is a perspective view of the present invention. It is a vertical side surface of the present invention. (A) is a longitudinal side view showing a state where the outer shell body is placed at a shallow water depth, and (b) is a state where the outer shell body is placed at a deep water depth. (I) is a state where the floor surface is leveled, (b) is a state where the floor surface is being inclined (c) is a state where the floor surface is inclined, and (d) is a state where the floor surface is inclined. It is each vertical side view shown. It is each vertical side view which shows the state which (i) inclines the floor surface and is carrying out stored goods, (b) inclines the floor surface and is carrying in the stored goods.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the undersea warehouse 1 of the present invention is a floor surface that divides the interior space vertically into a horizontal cylindrical water-resistant outer shell 2 that covers the entire outer periphery in an airtight manner. 3 is provided, and the storage chamber 4 for storing the stored product C is provided above the floor surface 3, and the buoyancy of the outer shell 2 is adjusted by exchanging the amount of seawater and air below. The buoyancy control chambers 5 are respectively formed.
The outer shell 2 is made of a thick iron plate, and in order to improve the water pressure resistance, it is preferable to take measures such as providing a rib on the inner surface of the iron plate to reinforce the plate surface or forming a multilayered wall surface. In addition, the magnitude | size of the diameter of the said outer shell body and the length of a horizontal direction are not specifically limited, It can design to the size according to the capacity | capacitance of stored goods.

The target storage C is a granular fluid agricultural product such as corn, peanuts, coffee beans, and wheat, in which particles are separated when taken in hand, and includes seeds such as grains. When these stocks C are derived from plant seeds, temperature control for maintaining quality is important. Further, it can be stored in liquids such as fresh water, chemicals, waste liquids, and petroleum. In the sea, a large temperature change does not occur every day like the ground, and the temperature is easily controlled because the temperature is almost constant.
Note that air management such as temperature management and humidity management in the storage chamber 4 can be performed, and although not illustrated, for example, a heater, a cooler, a humidifier, a dehumidifier, a temperature sensor, humidity in the storage chamber 4 It is also possible to provide a sensor, a horizontal sensor, etc., and to automatically control these devices with a computer.

Further, a carry-in portion 10 is provided on the ceiling surface of the outer shell 2 above the storage chamber 4, and a carry-out portion 11 is provided on the floor surface 3 of the storage chamber 4 so as to continue to the top surface of the floor.
The carry-in unit 10 and the carry-out unit 11 are provided with pressure-resistant doors that hermetically partition the storage chamber 4 and the seawater side outside the storage chamber 4 and can withstand a large water pressure received from seawater at a deep water depth.
Although not shown, the carry-in unit 10 can also be used at the same place as the carry-out unit 11.

  Furthermore, each door of the carry-in part 10 and the carry-out part 11 is provided with a drive opening and closing device that can be automatically opened and closed by the operation of a motor controlled by an electrical command by a warehouse manager's button operation, and the doors can be opened and closed remotely. To do so.

Further, the anchor 26 is lowered by hanging on the seabed K from a string-like mooring material 7 such as a wire or chain, and the water depth of the outer shell 2 is changed by changing the mooring width L of the mooring material 7 at the upper part of the anchor 26. The outer shell body 2 floating in the sea U is connected like an ad balloon floating in the air through a water depth adjusting mechanism 6 that adjusts the D position.
At that time, sliders 8 each holding the anchoring material 7 so as to be able to reciprocate up and down are attached to the lower portions of both ends of the outer shell body 2, and the outer periphery for moving the slider 8 in the circumferential direction of the outer shell body 2. A moving mechanism 9 is provided.
That is, the slider 8 of the outer periphery moving mechanism 9 is provided so as to hold the mooring material 7 of the water depth adjusting mechanism 6 so that the outer periphery moving mechanism 9 and the water depth adjusting mechanism 6 can be interlocked.
As shown in FIGS. 1 and 2, the water depth adjusting mechanism 6 and the outer peripheral moving mechanism 9 are provided symmetrically on both ends of the cylindrical outer shell body 2 to adjust the lengths of the two anchoring materials 7, respectively. Thus, the central axis of the outer shell 2 is set in a horizontal state.

The anchor 26 is fixed to the seabed K of the anchoring material 7 such that the outer shell 2 when the storage C in the storage chamber 4 is emptied and the buoyancy control chamber 5 is filled with air is in the sea. A metal or concrete anchor 26 having a weight that is a force to pull all in the seafloor direction against the buoyancy received is used.
In the embodiment shown in FIG. 1, two anchors 26 mooring both sides of the outer shell body 2 are used to fix the anchoring material 7 to each, and each anchoring material 7 is fixed to both ends of the outer shell body 2. In the sea, the outer shell 2 can be stably moored while maintaining the horizontal center direction in the horizontal direction. Although not shown, the weight of one anchor 26 is not lifted. If there are two anchoring materials 7 from one anchor 26, or one deep anchoring material 7 below the deep water depth that will not sink further, the upper anchoring material 7 A form branched into two is also possible.

Further, in order to take air into the buoyancy control chamber 5, a styrofoam float 14 is attached, floats on the sea surface, and the base of the ventilation pipe 13 having a sea vent 13b opened to the atmosphere is connected to the buoyancy control chamber. 5 is connected to a vent 13a provided at the upper part of 5 and air is forcibly taken in and out from the vent 13a by an air pump 24, and at the same time, from the vents 15 and 16 provided at the lower part of the buoyancy control chamber 5. A buoyancy control mechanism 12 that performs the intake and discharge of seawater in conjunction is provided.
That is, the amount of air is adjusted by adjusting the water level W of the seawater taken into the buoyancy adjusting chamber 5, and the buoyancy applied to the outer shell body 2 to be lifted varies depending on the amount of air.
The forced air in / out of the buoyancy control chamber 5 is performed by an air pump 24 that is operated by a motor, and in conjunction with this operation, a water absorption electromagnetic valve provided at the water inlets 15 and 16 on the lower wall surface of the buoyancy control chamber 5. 15a and the drainage electromagnetic valve 16a are electrically controlled to open and close.
Although FIG. 1 shows a mode in which the water inlets 15 and 16 for performing water absorption and drainage are connected at one location, the water inlets 15 and 16 for water absorption and drainage are provided separately, and water absorption solenoid valves are provided respectively. A configuration in which 15a and a drain electromagnetic valve 16a are mounted is also possible. The water inlets 15 and 16 provided with the water absorption electromagnetic valve 15 and the drainage electromagnetic valve 16 are provided with a water absorption pump and a drainage pump, and can be operated by computer control linked with the intake of air to forcibly absorb and drain water. It is also possible to do so.

  Operations for operating the water depth adjusting mechanism 6, the buoyancy control mechanism 12, and the outer peripheral moving mechanism 9 are performed by communication from the sea. The communication can be performed by underwater ultrasonic communication or infrared communication, but a communication cable provided along with the ventilation pipe 13 by arranging an antenna in the atmosphere at the marine vent 13b. By connecting to the operation control unit, it is possible to reliably perform remote control from land or ship.

As shown in FIGS. 1 and 2, the water depth adjusting mechanism 6 has a winding drum 18 that winds the mooring material 7 by the rotation of a motor 17 provided in the outer shell 2 at the center of the end of the outer shell 2. The anchoring width L can be changed by winding and sending out the anchoring material 7 passing through the slider 8 by forward and reverse rotation of the winding drum 18.
Then, as shown in FIG. 3, the outer shell body 2 that is about to float by buoyancy floats when the mooring width L is increased and the water depth D becomes shallow, and when the outer shell body 2 that is pulled downward is shortened, It sinks and the water depth D becomes deep.

  The buoyancy control mechanism 12 simultaneously performs air suction control by the air pump 24 and the opening of the drain electromagnetic valve 16a to increase the amount of air in the buoyancy control chamber 5 to increase buoyancy, and vice versa. In addition, the air is discharged from the air pump 24 and the water flow control of the water flow port 15 by opening the water absorption solenoid valve 15a is performed at the same time, and air is discharged from the buoyancy control chamber 5 to reduce the buoyancy. While adjusting the amount of air in the chamber 4, the weight of the main body of the subsea warehouse 1 of the present invention and the weight of the stored item C in the storage chamber 4, the amount of air in the storage chamber 4, and the air in the buoyancy control chamber 5 Balance in quantity and maintain an arbitrary water depth D to float in the sea. When the amount of air in the storage chamber 4 and the amount of air in the buoyancy adjusting chamber 5 are smaller than the total weight of each part and the buoyancy is relatively reduced, the outer shell body 2 sinks to the seabed. The buoyancy is controlled so that the buoyancy that allows the body 2 to float is always obtained.

And as shown in (a) of FIG. 3, if the mooring width L of the mooring material 5 is lengthened, the outer shell body 2 will rise, but at the same time, the seawater in the buoyancy control chamber 5 is replaced with air. The buoyancy can be increased to assist the floating of the outer shell body 2.
On the contrary, as shown in FIG. 3B, if the mooring width L of the mooring material 5 is shortened, the outer shell body 2 will sink, but at the same time, the air in the buoyancy control chamber 5 is replaced with seawater. Thus, the buoyancy can be reduced and the settling of the outer shell 2 can be assisted.

As shown in FIGS. 1 and 2, the outer periphery moving mechanism 9 is provided with a track 19 on which the slider 8 moves around the outer shell 2, and the slider 8 is mounted so that the track 19 can move.
For this reason, the slider 8 is provided with front and rear free running wheels 30 that rotate on the track 19, and the mooring material 5 is held between the free running wheels 30 in the front and rear to smoothly move up and down. A mooring material guide roller 29 is provided.
As shown in FIG. 4, the slider 8 can move on the track 19 in the circumferential direction of the outer shell 2 by pulling a chain or wire 21 by driving a motor 20 provided in the upper part of the storage chamber 4. Like that.
In FIG. 4, (a) shows a state in which the slider 8 is not moved horizontally on the floor surface. 4 (b) shows a state in which the floor surface is being inclined. At this time, when the slider 8 moves to the left side of the figure, the mooring material 7 is moved by the reaction of buoyancy generated in the outer shell 2. A tension that pulls downward is generated, and the slider 8 is moved downward by this tension. As a result, as shown in FIG. 4C, the outer shell 2 rotates and the floor surface is inclined. When the slider 8 is further moved to the left side of the figure, it is in a state of being inclined so as to stand the floor as shown in FIG.

As shown in FIG. 2 and FIG. 3, the wire 21 circulates the outer shell body 2 around the guide body 27, hangs on a guide wheel 27, and hangs on a winding drum 28. It can be set as the structure which becomes possible to pull the chain or the wire 21 by rotating.
3 and 4, since the winding drum 28 is provided inside, a guide wheel 27 is provided that bends and guides the wire 21 from the track 19 to the winding drum 28.

The rotation of the outer shell 2 performed by pulling the chain or the wire 21 causes the floor surface 3 on which the stored item C in the storage room 4 is placed to be inclined as shown in FIG. C rolls down due to its own weight. If there is the carrying-out part 11 ahead, the stored matter C will go out naturally.
The storage chamber 4 is levitated to the sea surface by the water depth adjusting mechanism 6 and the buoyancy control mechanism 12, and the slider 8 is moved to incline the floor surface 3 of the storage chamber 4. FIG. As shown in FIG. 4, the carrier B is waiting under the carry-out portion 11 and naturally enters the storage room C so that the stored item C flows into the luggage compartment.
When carrying in, as shown in FIG. 5 (b), the water depth adjusting mechanism 6 sinks the outer shell body 2 until it sinks, and the receiving port of the carrying-in part 10 projects above the sea surface. The stored material C may be poured into the transport pipe of the transport ship B.

In addition, when the stored item C is a grain, even if the grain is being stored deeply in the sea, the stored grain is stirred by rotating the outer shell 2 and tilting the floor 3 at any time. Exposure to controlled air can prevent spoilage and maintain freshness.
The exchange of the air inside the storage chamber 4 uses the ventilation pipe 13 provided with the buoyancy control mechanism 12, the middle of the ventilation pipe 13 is communicated with the storage chamber 4, an air pump is provided in the communication passage, This is possible by controlling the operation of the pump.

The buoyancy adjustment chamber 5 can be provided with a dividing wall 22 that partitions the indoor space into a plurality of spaces.
In this embodiment, as shown in FIGS. 1 and 2, the space is partitioned by the dividing wall 22, and the individual spaces 5a, 5b, 5c, and 5d are each airtightly independent.
For example, FIGS. 1 and 2 show an embodiment in which four partitioned spaces 5a, 5b, 5c, and 5d are provided.
In these individual spaces 5a, 5b, 5c, and 5d, seawater is put into the water level W in each space, and air accumulates in the space above it, and the buoyancy is adjusted by the amount of this air.
The inclination of both sides of the outer shell body 2 can be adjusted by the amount of winding of the mooring material 7 on both sides. By making each space partitioned by the dividing wall airtight independently, By changing the amount of air and making the buoyancy in the lateral direction of the outer shell 2 different, the buoyancy balance becomes different, so that the inclination of the floor surface 3 of the storage chamber 4 can be facilitated.
At that time, by tilting the central axis of the outer shell body 2 separately from the inclination due to the rotation of the outer shell body 2, the grain flows in the direction of the central axis by its own weight, similar to the inclination due to the rotation, The freshness of the grain can be maintained by being exposed to air at a constant temperature in the storage chamber 4.
In addition, even if one of the independent spaces leaks due to an accident or the like, it can be lifted by the buoyancy of the other space, so that safety is improved.

In addition, airtight buoyancy maintenance chambers 23 having a volume that can ensure buoyancy that allows the outer shell 2 to float even when seawater is full in the buoyancy control chamber 5 can be provided at both ends of the outer shell 2. .
In this embodiment, since seawater does not enter the buoyancy maintenance chamber 23, corrosion of internal metal parts due to salt water can be prevented, and the buoyancy maintenance chamber 23 includes a motor, a driving device such as an air pump 24, a battery, and the like. Various components and members such as an electronic board such as a power supply device, a control panel, and wiring, and a telecommunication cable can be arranged.

Further, the floor surface 3 can be provided with an inclination guide surface 25 that is inclined toward the carry-out portion 11.
In this embodiment, when the floor surface 3 is tilted by the movement of the slider 8 of the outer peripheral movement mechanism 9, the granular stored material C on the floor surface 3 is guided to the inclined guiding surface 25, and the stored material C is self-weighted. Then, it flows out toward the door where the unloading part 11 is opened. At this time, as shown in FIG. 5 (a), if the transport ship B is placed under the door, agricultural products such as grains flow out into the ship, leaving the stored product C in the storage room 4 left. It is possible to quickly carry it out.

(Procedure for unloading work)
The procedure of the carrying-out work is to first increase the buoyancy of the outer shell 2 by increasing the buoyancy of the outer shell 2 by exchanging the seawater inside the buoyancy control chamber 5 with air.
And the mooring width | variety L of the mooring material 7 by the said water depth adjustment mechanism 6 is lengthened, and it is made into the state of (i) from the state of (b) of FIG. 3, so that it is shown to (c) of FIG. Then, the outer shell body 2 is floated up to the sea surface S.
Further, as shown in FIGS. 4A to 4C, the floor surface 3 of the storage chamber 4 becomes higher than the sea level by almost discharging the seawater inside the buoyancy control chamber 5 and filling it with air. As shown in FIG. 5 (a), the outer shell body 2 can be lifted up to raise the carry-out portion 11 of the storage chamber 4 to the transport ship B to a position higher than the deck.
Then, the floor surface 3 is inclined so that the unloading part 11 of the storage chamber 4 faces downward, the unloading part 11 is levitated above the deck of the transport ship B, and the slider 8 is moved around by the outer periphery moving mechanism 9. Rotate in the direction to incline the floor surface 3 so that the unloading portion 11 of the storage chamber 4 faces downward, and by opening the unloading portion 11, the stored item C flows down the floor surface 3, and the carrier B It is carried out to.
In this way, the stored item C can be easily carried out by its own weight outflow.

(Procedure for import work)
As shown in FIG. 5B, the carrying-in procedure is to close the carry-out portion 11 of the outer shell 2 that has floated in the carry-out procedure, and to put seawater into the buoyancy control chamber 5 to reduce air. Furthermore, the outer shell 2 is submerged to the state where only the carry-in portion 10 above the storage chamber 4 is floated on the sea surface S by shortening the mooring width L of the mooring material 7 by the water depth adjusting mechanism 6. As a result, the storage room 4 is located below the carrier ship B, and when the loading section 10 is opened, the stored material C in the carrier ship B is carried into the storage room 4 so as to flow down from the transfer pipe.

  In the present invention, a string-like mooring material is moored on the sea floor and installed in a floating state in the sea, but the entire outer shell can be submerged under the surface of the water and moored at the bottom with the mooring material. If the water depth is so deep, it can be installed in rivers and lakes.
