Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a floating storage tank for storing jet fuel.

[Conventional technology]

At airports where jet aircraft take off and land, multiple sets of jet fuel receiving storage tanks, stationary storage tanks, and dispensing storage tanks are installed on land.

[Problems that the invention attempts to solve]

However, at airports with a large number of flights arriving and departing, the amount of jet fuel supplied is large, so many large storage tanks must be installed.

Therefore, the cost for constructing the foundation of the storage tank is high, and the construction period is also long. Furthermore, since the area occupied on land will be large, a large land area must be secured for the airport.

[Means for solving problems]

In order to solve the above-mentioned problems, in the present invention, intermediate storage tanks with approximately the same capacity are formed on both sides of a central storage tank formed in the center of the floating body, and further outer tanks with approximately the same capacity are formed on the outside of each intermediate storage tank. The storage tank is divided into sections, and these three types of central storage tank, each intermediate storage tank, and each outer storage tank are arbitrarily used as a jet fuel receiving tank, a static storage tank, and a discharge storage tank, and the intermediate storage tanks and each outer storage tank are arranged at the bottom, respectively. A jet fuel floating storage tank was constructed by connecting and communicating with the pipes.

[Effect]

After the jet fuel floating storage tanks are constructed in a dock, they are towed and moored in parallel in a pool.

Since the central storage tank is located at the center of the floating body, even if the amount of liquid changes due to liquid injection and drainage, the floating body remains horizontal and only the water depth changes.

The intermediate storage tank and the outer storage tank are also located symmetrically with respect to the longitudinal direction of the floating body, and each intermediate storage tank and the outer storage tank are communicated with each other, so that the liquid level is the same, and even if the liquid volume fluctuates, the floating body will not change. It simply floats and sinks while remaining horizontal.

If these three types of storage tanks are used as a receiving storage tank, a stationary storage tank, and a discharging storage tank for jet fuel, foundation work becomes unnecessary and the structure becomes compact.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figures 1 to 4 show an embodiment of the present invention,
A central storage tank 3 for a stationary storage tank 2 is partitioned in the center of a floating body 1 made of concrete, and intermediate storage tanks 5 of approximately the same capacity for dispensing storage tanks 4 are partitioned on both sides of the central storage tank 3. On both sides of each intermediate storage tank 5, outer storage tanks 7 are formed for receiving storage tanks 6 and have approximately the same capacity. Each of the storage tanks 3, 5, and 7 has an iron plate on the inside, and the surface thereof is coated with an epoxy resin lining.

Each intermediate storage tank 5 is connected to its bottom with a pipe 8 so as to communicate with each other, and each of the outer storage tanks 7 is similarly connected with a pipe 9 so as to communicate with each other.

A steel roof 10 is provided above each of the storage tanks 3, 5, and 7.
A pan 11 is floated on the liquid surface of each storage tank 3, 5, and 7 to suppress evaporation of the jet fuel oil, and the space above the pan 11 is naturally ventilated by a ventilation fan installed at a required position. It is set as.

A suction port 14 of a bendable nozzle 13 for injecting and discharging fuel oil is provided at the lower part of each pan 11, and a pipe 15 is connected to the base of each bendable nozzle 13, and each pipe 15 is connected to the central storage tank. switchably connected to the pump in the pump chamber 12 provided in the center of 3,
Oil can be conveyed between the receiving, standing, and discharging storage tanks 3, 5, and 7.

Further, a foam fire extinguishing device is provided in each of the storage tanks 3, 5, and 7, and the entire surface of the pan and seal is covered with foam in the event of a fire. Also, water sprinkler equipment is installed on the roof 10, and in the event of an adjacent fire, water is sprinkled over the entire surface.

After the jet fuel floating storage tanks 16 described above are constructed in a dock, they are towed, a plurality (in this embodiment, five sets) are arranged in parallel, and they are housed in a pool 17 with the four sides closed. The water in the pool 17 is communicated with the open sea 20 through a water pipe 18. As a result, the water level in the pool 17 can always be kept the same as the water level in the open sea 20. Each of the floating storage tanks 16 is moored to the ground. Furthermore, there is a mixed liquid storage tank 1 on the ground.
9 is installed close to the floating body storage tank 16.

When jet fuel oil is stored in the jet fuel floating storage tank 16 installed close to the airport as described above, the oil is pumped into the outer storage tank 7, which is the receiving storage tank 6, by the oil pump in the pump room 12. Since the outer storage tanks 7 are mutually connected through piping 9, the liquid level in each outer storage tank 7 gradually increases while maintaining the same liquid level, and storage is completed. Since the outer storage tanks 7 are arranged symmetrically, even if the amount of stored liquid increases, the liquid level remains the same as described above, so that it is balanced and does not tilt.

Next, the oil pump in the pump chamber 12 is used to transport fuel oil from the receiving tank 6 to the central storage tank 3, which is the stationary storage tank 2. in this case,
The liquid level in each outer storage tank 7 gradually decreases while remaining at the same level, and the liquid level in the central storage tank 3 gradually rises. However, since the central storage tank 3 is located in the center of the floating body 1, the floating body
balance is maintained.

Furthermore, when the supernatant liquid is sent from the stationary storage tank 2 to the left and right intermediate storage tanks 5, which are the payout storage tank 4, the same procedure as described above is carried out, and the left and right intermediate storage tanks 5 are also communicated with each other by piping 8. Moreover, since they are arranged symmetrically, the liquid height is at the same level and balance is maintained.

Similarly, when the supernatant liquid is discharged from the dispensing storage tank 4 to the mixed liquid storage tank 19 on land, even if the amount of stored liquid decreases, it decreases equally on both sides, so the floating body storage tank 16 is kept horizontal without tilting.

The jet fuel floating storage tank of the present invention is not limited to the above-described embodiments, and the uses of the central storage tank, intermediate storage tank, and outer storage tank may be changed as desired without departing from the gist of the present invention. Of course, various changes can be made.

[Effect of idea]

As described above, the jet fuel floating storage tank of the present invention can produce various excellent effects as described below.

() Because it is a floating structure, there is no need for foundation work as in the past, significantly reducing construction costs.
The construction period can be significantly shortened.

() Since each intermediate storage tank and each outer storage tank are arranged on the left and right with the central storage tank in the middle, and each intermediate storage tank and each outer storage tank are connected and communicated with each other through piping, the liquid volume in either storage tank does not increase or decrease. Also, the floating body is balanced and kept horizontal.

() Since the central storage tank, intermediate storage tank, and outer storage tank can be used as storage tanks for receiving, standing, or discharging, a set of storage tanks can be placed adjacent to each other, making it possible to install multiple sets compactly. I can do it.

() Construction is easier because it can be built inside the dock and then towed.

() All pumps are installed in the pump room, making maintenance easier.

() If the floating body is made of concrete, maintenance of the external surface is not required.
