Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a simple underwater oil storage tank equipped with a large number of small tanks.

(Prior Art) Conventionally, as technical documents regarding oil storage tanks moored in the sea, the following proposals have been made, for example.

That is, Japanese Utility Model Publication No. 58-42315 discloses a breakwater and water-shielding levee that cuts off the sea and divides it into a seawater space of a required size, a plurality of oil storage tanks floating in the seawater in the seawater space, An underwater oil storage device is described that is mainly configured with a connecting passage arranged between oil storage tanks.

In addition, Publication No. 58-42316 describes a moored type oil storage tank for ice seas that includes a truncated cone-shaped disk-shaped oil storage tank moored on the sea, and a crane, tanker mooring device, and oil transfer pipe installed on the upper part of this oil storage tank. tank is listed.

(Problems) In the above-mentioned conventional technology, since the oil storage tank is installed floating in the sea, there is no need to secure land for an oil storage base, and it is possible to avoid ground subsidence and fire prevention risks, etc. Advantages are listed. However, these conventional technologies result in a large-scale oil storage base and the cost of constructing the equipment is high. Another problem was that the oil storage tank could not be installed or removed individually and could not be used as a simple small-scale oil storage tank.

(Means for Solving the Problems) The present invention has been devised in view of the above problems, and is a simple oil storage system that is inexpensive to construct and that allows small tanks to be increased, decreased, or removed as needed. The purpose is to provide tanks, and the gist is as follows.
An outer fence made of a mesh of synthetic resin fibers, glass fibers, animal fibers, metal wires, etc., which is moored in the sea, and a polyurethane rubber, etc., which is moored with appropriate gaps within this outer fence. An inner fence formed by appropriately connecting fence pieces;
It consists of a large number of small tanks each having a mouth and a rope locking recess that are housed within this inner fence.
The number of the small tanks can be increased or decreased according to the amount of oil stored, and the inner fence can be expanded and contracted by lengthening or shortening the length of the fence pieces.

(Function) The outer fence is made of synthetic resin fibers, glass fibers, animal fibers, metal wires, etc., and is therefore inexpensive, and can be easily installed underwater, requiring only a short installation time. good. Furthermore, this outer fence can block large floating objects such as driftwood. In addition, since inner fences made of rubber such as polyurethane rubber are installed at appropriate intervals in the seawater space divided by the outer fence, even small floating objects can be blocked from the inner fence. , the small tank housed inside the inner fence can be sufficiently protected. Furthermore, since this inner fence is composed of consecutive fence pieces, it is easy to adjust the seawater space divided by the inner fence by increasing or decreasing the number of consecutive fence pieces. By increasing or decreasing the number of consecutively installed inner fences, it is possible to lengthen or shorten the inner fence, and the number of small tanks to be stored inside the fence can be increased or decreased. A plurality of the small tanks to be stored can be easily connected by ropes or the like through the rope locking recesses, and the small tanks can be firmly connected to each other and can be easily removed. Therefore, each small tank can be easily taken out as needed, and since each small tank is equipped with a mouth that can be opened and closed, the storage inside each tank can be easily carried out. You can extract as much oil as you need.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows an overall plan view of the oil storage tank of this example, and FIG. 2 shows a side view thereof. Note that FIG. 3 is a side view of the inner fence, and FIG. 4 shows the connected state of the small tanks housed in the inner fence.
FIG. 5 shows how the fence pieces constituting the inner fence are connected.

In the figure, reference numeral 1 denotes an outer fence, which is made of a net of filaments made of synthetic resin fibers, glass fibers, animal fibers, metal wires, etc., and is framed in the shape of a rectangular frame, with a seawater space inside the frame. K, and is connected to the seabed and moored in the ocean via a chain 2 or the like.

Reference numeral 3 in the figure indicates floats arranged at equal intervals on the upper edge of the outer fence 1, which float the upper edge of the outer fence 1 above the sea surface.

4 in the figure is an indicator flag provided on this float 3 and erected above the sea surface.

In the figure, reference numeral 5 denotes an inner fence which is moored and connected to the seabed via a chain 6 with a gap between the outer fence 1 and the seawater space K in the outer fence 1, and is shaped like a box frame with an open top. A seawater space Y is formed within the frame. The inner fence 5 is composed of a large number of rectangular plate-shaped fence pieces 7 made of reinforced rubber such as polyurethane rubber or other rubber, arranged vertically and horizontally. In order to facilitate connection with the fence pieces 7, for example, protruding pieces 8 and fitting recesses 9 are provided, and by fitting the protruding pieces 8 into the fitting recesses 9, the fence pieces 7 are successively connected. It becomes wall-like as a whole (see Figure 5).

In the seawater space Y formed by the inner fence 5, a large number of rectangular box-shaped small tanks 10 are housed in a stacked manner.

Each small tank 10 has an opening 11 that can be opened and closed.
is provided, through which the small tank 10 can be filled with oil or the oil stored in the tank 10 can be taken out to the outside. Further, a rope locking recess 12 is vertically provided in the shape of a groove in the center of the side outer wall of each small tank 10.
This rope locking recess 12 can increase the wall strength of the small tank 10, and by winding and locking a rope etc. in the groove, each of the stacked small tanks 10 can mutually connect the rope, etc. connected by.

The oil storage tank of this example configured in this way is
The outer fence 1 can be constructed from an easily available and inexpensive net, and the outer fence 1 can block relatively large floating objects such as driftwood floating in the ocean. Also, inner fence 5
Since it is constructed by connecting a large number of fence pieces 7, the seawater space Y can be easily increased or decreased by lengthening or shortening the length of the fence pieces 7. The number of tanks 10 can be increased or decreased. Moreover, since the inner fence 5 is made of easily available rubber, it is easy to manufacture, and its elasticity can sufficiently protect the small tank 10 housed inside. It is also believed that mooring will be made easier without surfacing out of the sea.

Furthermore, each small tank 10 can be easily taken out and carried one by one, and oil can be taken out or filled through its mouth 11, allowing for relatively small amounts of oil to be taken out and taken out frequently. Become.

Therefore, the oil storage tank of this example is expected to be used as a fuel storage tank at marine airports, etc., for example.

Since the oil storage tank of this example is moored in the sea, it does not require special land and is safe against earthquakes, as well as being superior in terms of fire safety.

(Effects) The present invention consists of an outer fence made of a mesh of synthetic resin fibers, glass fibers, animal fibers, or metal wires, which is moored in the sea, and a polyurethane fence moored at appropriate intervals within the outer fence. An inner fence consisting of fence pieces made of reinforced rubber or other rubber, and a large number of small tanks having openings that can be opened and closed and rope locking recesses housed within the inner fence. By increasing or decreasing the number of small tanks according to the amount of oil stockpiled, and by making the inner fence expandable and retractable by lengthening and shortening the length of the fence pieces, it can be constructed easily and inexpensively, and can be constructed as needed. The number of installed small tanks can be easily increased or decreased, and this has a highly practical effect as a relatively small-scale underwater oil storage tank.
