Description

Technical Field

[0001] The utility model relates to the technical field of transport ships, in particular to a novel cargo hold insulation structure of a liquid hydrogen transport ship. Background Art

[0002] Liquid hydrogen is a liquid obtained by cooling hydrogen gas. It is widely used. When using ships to transport liquid hydrogen, it is necessary to ensure that the cargo hold of the ship has good thermal insulation to avoid the vaporization of liquid hydrogen.

[0003] The existing patent document with technical disclosure number CN217100375U provides a type B liquid cargo tank spray insulation inner layer leakage protection structure for ships. The type B liquid cargo tank spray insulation inner layer leakage protection structure for ships in this application adopts a polyurethane open-cell foam layer to solve the problem of diversion channels when liquid cargo leaks when the type B tank spray method occurs, and at the same time enhances the low-temperature adhesion and crack resistance between the insulation layer and the storage tank, so that when the storage tank cools and shrinks, the insulation layer remains attached to its surface, avoiding penetrating cracks and falling due to low-temperature shrinkage.

[0004] However, the existing cargo hold insulation structure of transport ships is not easy to ensure that it has a good buffering effect when in use. During the transportation of liquid hydrogen by the ship, when it is impacted by external force, it will easily cause a certain amount of shaking to the cargo hold.
