Abstract

PURPOSE:To contrive the storing of grain for a long period of time on the bottom of the sea where the temperature is low and small in its variations by installing a control tank and storage tanks adjacent thereto on the sea bottom and unloading grain thereinto through a carry-in hopper on a floating operating platform. CONSTITUTION:When a transport ship A is brought alongside a floating operating platform 4, grain is unloaded therefrom into a carry-in hopper 5 and sent successively into individual storage tanks 2 through a transfer pipe 6. To carry the grain out, compressed air is delivered into an air introducing part 12a by operating a compressor 14 and the discharge opening 2b of the storage tank 2 is opened to send the grain into a discharge hopper 10 through an air supply pipe 12. The grain is then delivered into a carry-out hopper 8 on the floating operating platform 4 by a belt 16 with buckets.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an underwater storage facility for storing stored materials such as grains in the sea.

Conventional technology Traditionally, grains such as rice were stored in silos built above ground.

Problems to be solved by the invention By the way, when storing grain for a long period of time in an above-ground silo,
It is necessary to keep the temperature constant, which poses a problem in that the amount of storage cannot be increased very much and refrigeration equipment is required.

Therefore, an object of the present invention is to provide an underwater storage facility that can solve the above problems.

Means for Solving the Problems In order to solve the above problems, the underwater storage facility of the present invention includes:
A control tank and a plurality of storage tanks adjacent to the control tank are sunk on the seabed, and a work platform provided at a predetermined position above the sea surface is connected to the control tank with a guide tube, A transfer pipe is provided to transfer the stored material unloaded by the stored material transport hopper to each of the storage tanks, and a transport device for transporting the stored material in the storage tank to the control tank, and a transport device for transporting the stored material in the storage tank to the control tank. It is equipped with a conveyor device that transports stored items to a hopper for carrying out on a workbench.

Effect: In the above configuration, when storing stored items such as grains,
When the grain is loaded from the carrier into the loading hopper on the workbench, the grain is transferred to the storage tank via the transfer pipe and stored at a low temperature for a long period of time. In addition, when transporting grain from a storage tank, the grain is first transported from the storage tank to a control tank by a transport device, then transported to a workbench by a conveyor device, and then transferred to a transport vessel via an unloading hopper on the workbench. loaded.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3. 1 is a cylindrical control tank sunk on the seabed, and 2 is a plurality of cylindrical storage tanks, for example six, arranged adjacent to the control tank 1. Note that these tanks 1 and 2 are made of concrete, for example. A guide frame 3 is provided above the sea surface to protrude from the control tank 1, and this guide f! ? i3
a specified height above the sea level (a position unaffected by waves)
A work platform (drawer's base) 4 for mooring a transport ship A for storing stored goods, such as grain, and for loading and unloading the grain is fixed to the base. This workbench 4 is provided with a carry-in hopper 5 for carrying in grain from the carrier ship A, and this carry-in hopper 5 and each storage tank 2 are connected via a transfer pipe 6 inserted through a guide frame 3. It is connected. Note that a distribution valve (not shown) is installed between the chute portion 5a of the carry-in hopper 5 and the six transfer pipes 6 from each storage tank 2 in order to transfer the grains to the storage tanks 2 in order. A distribution pipe 7 having a structure is interposed therebetween. Further, the workbench 4 is provided with a carry-out hopper 8 for carrying out the grains to the carrier ship A, and the grains in each storage tank 2 are transported once to the control tank 1 by a pneumatic transport device (transport device) 9. After being dispensed into the dispensing hopper 10 inside, the guide f! J
A conveyor device 11 inserted into the workbench 3 conveys the workpiece to the unloading hopper 8 of the workbench 4 . That is,
An air transport pipe 1 is connected to the outlet 2b at the center of the bottom of the hopper-like bottom wall 2a of each storage tank 2 via an on-off valve (not shown).
2 is connected, and the other end is inserted through a communication path 13 between the storage tank 2 and the control tank 1 and opened into the dispensing hopper 10, and air is introduced into one end of the air transport pipe 12. A compressed air supply pipe 15 from a compressed air supply device 14 disposed in the control tank 1 is connected to the portion 12a and the air transport pipe 12 midway.

Therefore, when compressed air is supplied from the compressed air supply pipe 15 to the air introduction section 12a and the air transport pipe 12, the grains in the storage tank 2 are discharged into the air transport pipe 12 by the ejector action, and the compressed air It is transported into the dispensing hopper 10. Further, the conveyor device 11 (also referred to as a particle belt conveyor) includes an outlet 1 of a dispensing hopper 10 in the control tank 1.
A belt with packets 16 (the packets are also made of rubber) is wound endlessly between the lower position of 0a and the upper position of the input port 8a of the carry-out hopper 8 on the workbench 4, and its guide shaft 17 and a drive +1618. The control tank 1 includes each storage tank 2.
A monitoring center 19 is provided that can monitor the internal state of the
Furthermore, an elevator device 20 for transporting workers between the work platform 4 and the control tank 1 is disposed within the guide frame 3. Note that 21 is a control room for the entire storage facility provided on the workbench 4.

In the above configuration, when storing grains in the storage tank 2, the carrier ship A is brought alongside the workbench 4, and the grains are unloaded into the carry-in hopper 5 by the unloading device of the carrier ship A, and then the grains are unloaded. Grain is sequentially transferred to each storage tank 2 via a distribution pipe 7 and a transfer pipe 6. After the transfer of the grains is completed, dry air is sealed to prevent moisture, and the distribution valve of the distribution pipe 7 (or other appropriately placed on-off valve) is closed to store the grains. In this way, storing grains on the ocean floor allows them to be stored at low temperatures (
For example, at a depth of 80 to 100 meters under the sea, grains can be stored in large quantities with little temperature change (about 10 to 15 degrees Celsius).

Next, when carrying out grains from the storage tank 2, first operate the compressed air supply device 14 to supply compressed air to the air introduction section 1.
2a and the air transport pipe 12, and the on-off valve of the discharge port 2b of the storage tank 2 is opened to transport the grains into the payout hopper 10 via the air transport pipe 12. Next, the conveyor equipment W , 11 (of course, they may be activated in advance) and the discharge port 10a of the unloading hopper 10 is opened, the grains are conveyed into the unloading hopper 8 of the workbench 4 by the belt 16 with packets. ,
Then, it is loaded onto the carrier ship A via this unloading hopper 8.

Effects of the Invention According to the configuration of the present invention described above, stored materials such as grains can be stored on the seabed at low temperatures and with little temperature change, so a large amount of stored materials can be stored for a long period of time without the need for a refrigeration device. It can be stored.
