The invention provides a low-temperature liquid cargo leakage protection device of an independent liquid tank. The device comprises a liquid collecting part fixed on the side of the liquid tank and aliquid containing part fixed on the side of a ship body, wherein the liquid collecting part and the liquid containing part are separated and are correspondingly arranged up and down; the liquid collecting part is provided with a liquid outlet, the liquid containing part is provided with a liquid inlet, the liquid outlet and the liquid inlet are formed in an up-down corresponding mode, and the sizeof the liquid inlet is larger than that of the liquid outlet; and the low-temperature liquid cargo leakage protection device is simple in structure, capable of avoiding low-temperature brittle failure of a ship body structure due to the fact that low-temperature liquid cargo flows into the ship body structure, and safe and reliable; and heat transfer between the low-temperature liquid cargo in the liquid tank and the ship body structure in a normal operation state and a special damage state can be effectively isolated, so that the ship body structure can adopt a common steel plate instead oflow-temperature special steel, the economy is improved, the influence of the environment temperature on the evaporation rate of the low-temperature liquid tank is reduced, and the technical index is improved.

    本发明提供一种独立液舱的低温液货泄漏保护装置,包括固定在液舱侧的集液部和固定在船体侧的盛液部,集液部与盛液部隔空、上下对应设置;集液部设置有出液口,盛液部设置有进液口,该出液口与进液口上下对应设置,且进液口的尺寸大于出液口的尺寸,该低温液货泄漏保护装置结构简单,避免低温液货流入至船体结构导致船体结构产生低温脆性破坏,安全可靠;能够有效地隔绝了液舱低温液货与船体结构在正常运营状态和破坏特殊状态下的热量传递,使得船体结构可以采用普通钢板,而非低温特种钢,提高了经济性,也减少环境温度对低温液舱蒸发率的影响,提高了技术指标。
