However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. In addition, in order to clearly explain the present invention in the drawings, portions irrelevant to the present invention have been omitted, and like reference numerals are used for like portions throughout the specification.

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a sectional view showing an embodiment of a storage tank structure of the present invention, fig. 2 is an enlarged sectional view of a portion "a" in fig. 1, fig. 3 is a sectional view showing another embodiment of a storage tank structure of the present invention, and fig. 4 is a schematic view showing a support portion of a storage tank structure of the present invention.

Referring to fig. 1, 2 and 4, the storage tank structure according to an embodiment of the present invention includes a support part 110, a heat insulator 120, a heat insulator 130, a plate part 140, and an auxiliary plate 150.

The support 110 is provided on the bottom surface of the hull 20 to support the storage tank 10. The support 110 is provided between the foundation 30 contacting the bottom surface of the hull 20 and the storage tank 10, and supports the load of the storage tank 10 and transmits the load of the storage tank 10 to the bottom surface of the hull 20.

The supporting portion 110 may be made of wood, but the material of the supporting portion 110 is not limited to wood. The support portion 110 may be formed in a rectangular parallelepiped shape, but may also be formed in a cylindrical shape.

The heat insulating material 120 is closely attached to both side surfaces of the support part 110, and the heat insulating material 120 may be formed of a material such as urethane foam. The support portion 110 is provided with a groove 111 at a predetermined height, and the end of the plate portion 140 is fastened to the groove 111.

The groove 111 may be provided at a predetermined height of the support 110, and may be provided at a middle portion of the height of the support 110, but the groove 111 may be formed at a portion other than the middle portion in order to prevent leakage of the liquefied natural gas.

When the groove 111 is positioned at the upper portion of the support 110, a moving path of the leaked natural liquefied gas can be shortened.

Referring to fig. 4, it is shown that the groove portion 111 is provided at an intermediate height of the support portion 110, when the groove portion 111 is provided in the support portion 110When the height of the air conditioner is within the range,

shape or shape insertable into and fixable to said groove portion 111

The jig 180 having a shape other than the shape is inserted into and fixed to the groove 111, so that the support 110 can be stably transferred by the lifting rope 190(lifting rope) connected to the jig 180. In this embodiment toThe jig 180 is exemplified in shape, but as long as it can be stably inserted and fixed in the groove portion 111,

various shapes such as a shape, a T shape, etc. are possible and are not limited to

And (4) shaping.

In this case, in order to insert and fix the jig 180, the groove portion 111 is cut at a preset length and a preset height perpendicular to the height direction of the support portion 110.

Referring to fig. 2, the plate part 140 extends a predetermined length along the longitudinal direction of the groove part 111, and is provided to prevent leakage and further progress of the lng.

One end of the plate portion 140 is inserted into the groove portion 111 and is fastened to the inner surface of the groove portion 111 by a fastening means 143. The plate portion 140 may be formed in a straight line or T-shape in cross section, but may be formed in a cross section as shown in FIG. 2

And (4) shape. However, the section of the plate portion 140 is not limited to the "T" shape or

And (4) shaping.

Form a cross section

The shape means that one end of the plate portion 140 is bent by 90 degrees, and the other end of the plate portion 140 has a predetermined length and maintains a linear shape.

Since the plate portion 140 has

The shape of the plate portion 140 increases the coupling rigidity when the plate portion is fastened to the groove portion 111, and the plate portion is stably fixed to the inner surface of the groove portion 111, and since the other end portion maintains a straight shape, the thickness thereof can be reduced, and leakage of the liquefied natural gas and further leakage thereof can be prevented.

The groove 111 is filled with an adhesive 145. That is, a portion other than the plate portion 140 in the inside of the groove portion 111 may be filled with the adhesive portion 145. The adhesive portion 145 may be formed of a low-temperature adhesive or the like.

The thermal insulator 130 is disposed between the side surface of the support part 110 and the thermal insulator 120, and serves as a passage for transferring ultra-low-temperature goods (liquefied natural gas) loaded in the storage tank 10 when the ultra-low-temperature goods leak.

The flame-proof member 130 is formed to be porous, and one end of the flame-proof member 130 is connected to the plate 141 of the plate portion 140.

An auxiliary plate 150 is provided below the heat insulator 120, and the auxiliary plate 150 is fastened to a predetermined position by a fastener 151.

The auxiliary plate 150 stably supports the lower portion of the heat insulator 120 and prevents leakage of the lng leaking along another path in advance.

The auxiliary plate 150 may be formed longer than the plate part 140.

In the past, some of the heat insulators are formed to correspond to the thickness of the groove portions, and therefore, additional operations are required to seal the side surfaces of the support portions and the heat insulators and the flame insulators.

According to the present invention, since the plate portion is provided at the groove portion, the installation operation can be easily performed, and it is not necessary to perform an additional operation for sealing the gap between the support portion, the heat insulator, and the flame insulator, and the leakage of the liquefied natural gas can be stably prevented.

According to another embodiment of the present invention, the fuel barrier 130 extends from the upper portion of the support 110 to between the adjacent support 110, and the lng leaked through the discharge hole 160 is collected to the trap part 170. The discharge holes 160 are formed of a porous material. An end of the discharge hole 160 may be connected to at least one side of the flame-proof member 130. That is, in the present invention, the discharge hole 160 may refer to a member for discharging the leaked lng moving along the fuel barrier 130 to the trap part 170.

The lng that does not leak through the plate part 140 may move along the adiabatic member 130 extending between the support parts 110 and be trapped at the trap part 170 provided between the support parts 110.

The discharge hole 160 and the trap part 170 may be provided in one piece at an intermediate portion between the support parts 110, but may be provided in plural pieces adjacent to a portion corresponding to the horizontal extension length of the plate part 140 or the auxiliary plate 150.

The trap 170 may be provided on the hull bottom plate 20, but may be disposed adjacent to the lower portion of the heat insulator 120.
