Abstract

A cryogenic liquid storage apparatus includes an inner container configured to store a cryogenic liquid, an inner holder disposed at the inner container, an outer container that surrounds the inner container, an outer holder disposed at the outer container, and a support wire that is a single body defining a closed-loop shape passing through the outer holder and the inner holder. The support wire is configured to support the inner container with respect to the outer container.

First claim

What is claimed is:

1 . A cryogenic liquid storage apparatus comprising:
an inner container configured to store a cryogenic liquid; an inner holder disposed at the inner container; an outer container that surrounds the inner container; an outer holder disposed at the outer container; and a support wire that is a single body defining a closed-loop shape passing through the outer holder and the inner holder, the support wire being configured to support the inner container with respect to the outer container.

2 . The cryogenic liquid storage apparatus of claim 1 , wherein the outer holder comprises a plurality of outer holder members that are circumferentially spaced apart from one another and arranged about an axis of the inner container, and
wherein the support wire passes through the plurality of outer holder members.

3 . The cryogenic liquid storage apparatus of claim 2 , wherein at least any one of the plurality of outer holder members is configured to move relative to the outer container in a direction toward or away from a center of the outer container.

4 . The cryogenic liquid storage apparatus of claim 3 , wherein the plurality of outer holder members comprise:
a movable outer holder member configured to move relative to the outer container in a direction toward or away from the center of the outer container, the movable outer holder member being configured to adjust tension of the support wire based on moving relative to the center of the outer container; a first stationary outer holder member disposed at the outer container and spaced apart from the movable outer holder member in a clockwise direction about the axis of the inner container; a second stationary outer holder member disposed at the outer container and spaced apart from the first stationary outer holder member in the clockwise direction; and a third stationary outer holder member disposed at the outer container and spaced apart from the second stationary outer holder member in the clockwise direction.

5 . The cryogenic liquid storage apparatus of claim 4 , wherein the movable outer holder member and the second stationary outer holder member are disposed on a first reference line crossing the axis of the inner container, and
wherein the first stationary outer holder member and the third stationary outer holder member are disposed on a second reference line crossing the first reference line.

6 . The cryogenic liquid storage apparatus of claim 5 , wherein:
the movable outer holder member is disposed at a 12 o'clock position with respect to the axis of the inner container; the first stationary outer holder member is disposed at a 3 o'clock position with respect to the axis of the inner container; the second stationary outer holder member is disposed at a 6 o'clock position with respect to the axis of the inner container; and the third stationary outer holder member is disposed at a 9 o'clock position with respect to the axis of the inner container.

7 . The cryogenic liquid storage apparatus of claim 2 , wherein each of the plurality of outer holder members comprises:
an outer holder body that is disposed at the outer container and defines an outer holder accommodation portion accommodating the support wire.

8 . The cryogenic liquid storage apparatus of claim 7 , wherein the outer holder accommodation portion comprises an outer curved seating portion that is in contact with the support wire.

9 . The cryogenic liquid storage apparatus of claim 4 , comprising:
a holder mover configured to be disposed at the outer container and to move the movable outer holder member in the direction toward or away from the center of the outer container.

10 . The cryogenic liquid storage apparatus of claim 9 , wherein the holder mover comprises:
a fixing block configured to be fixed to the outer container, the fixing block having a through-hole; and an adjustment bolt configured to pass through the through-hole and to be fastened to a bolt hole defined in the movable outer holder member, and wherein the movable outer holder member is configured to be moved in the direction toward or away from the center of the outer container based on rotation of the adjustment bolt.

11 . The cryogenic liquid storage apparatus of claim 1 , wherein the inner holder comprises a plurality of inner holder members that are circumferentially spaced apart from one another and arranged about an axis of the inner container, and
wherein the support wire passes through the plurality of inner holder members.

12 . The cryogenic liquid storage apparatus of claim 11 , wherein the inner container has a first quadrant region, a second quadrant region, a third quadrant region, and a fourth quadrant region that are defined about the axis of the inner container, and
wherein the plurality of inner holder members comprise:
a first inner holder member disposed in the first quadrant region of the inner container;
a second inner holder member disposed in the second quadrant region of the inner container and spaced apart from the first inner holder member in a clockwise direction about the axis of the inner container;
a third inner holder member disposed in the third quadrant region of the inner container and spaced apart from the second inner holder member in the clockwise direction; and
a fourth inner holder member disposed in the fourth quadrant region of the inner container and spaced apart from the third inner holder member in the clockwise direction.

13 . The cryogenic liquid storage apparatus of claim 12 , wherein the first inner holder member and the third inner holder member are symmetric with respect to the axis of the inner container, and
wherein the second inner holder member and the fourth inner holder member are symmetric with respect to the axis of the inner container.

14 . The cryogenic liquid storage apparatus of claim 11 , wherein each of the plurality of inner holder members comprises:
an inner holder body that defines an inner holder accommodation portion accommodating the support wire.

15 . The cryogenic liquid storage apparatus of claim 14 , wherein the inner holder accommodation portion comprises an inner curved seating portion that is in contact with the support wire.

16 . The cryogenic liquid storage apparatus of claim 1 , wherein the inner holder is disposed at an end of the inner container, and
wherein the outer holder is disposed at an end of the outer container facing the end of the inner holder.

17 . The cryogenic liquid storage apparatus of claim 1 , wherein the inner holder comprises an inner holder drum disposed at the inner container, and
wherein the support wire is wound around the inner holder drum along a circumferential direction of the inner holder drum.

18 . The cryogenic liquid storage apparatus of claim 17 , wherein the inner holder drum comprises:
a drum main body that is disposed at the inner container and defines a drum accommodation portion accommodating the support wire.

19 . The cryogenic liquid storage apparatus of claim 18 , wherein the drum accommodation portion comprises a drum curved seating portion that is in contact with the support wire.

20 . The cryogenic liquid storage apparatus of claim 1 , wherein the support wire is made of at least one of Zylon® or Kevlar®.
