The invention relates to a cargo machinery room top structure integrated with a liquid accumulation groove, which comprises a deck, a deck cross beam, a deck longitudinal bone, a wing structure, a liquid accumulation groove bottom plate and a liquid accumulation groove side wall plate, the deck is positioned at the top of a cargo machinery room, the liquid accumulation groove is arranged above the deck, and the deck cross beam and the deck longitudinal bone form a supporting framework to support the deck. The edge of the deck protrudes and is supported by a wing structure, the wing structure is fixed on a side wall plate of the liquid accumulation tank, and an isolation space is formed between the lower part of a bottom plate of the liquid accumulation tank and the deck. According to the cargo mechanical chamber top structure integrated with the liquid accumulation groove, the top of the cargo mechanical chamber is of a common carbon steel plate structure, and the cost is reduced; the liquid accumulation tank and related components are of stainless steel structures and are prevented from being damaged by low-temperature liquefied natural gas; a wing structure is adopted to support the liquid accumulation tank, so that the liquid accumulation tank is combined with the cargo mechanical chamber, and materials and space are saved; the deck of the cargo machinery room is provided with holes, so that welding operation of constructors is facilitated.

    本发明涉及一种集合积液槽的货物机械室顶部结构,包括甲板、甲板横梁、甲板纵骨、翅膀结构、积液槽底板、积液槽侧壁板,甲板位于货物机械室的顶部,积液槽布设在甲板的上方,甲板横梁和甲板纵骨组成支撑骨架以支撑甲板,甲板的边缘凸出并通过翅膀结构支撑,翅膀结构固定在积液槽侧壁板上,积液槽底板下方与甲板之间形成隔离空间。本发明的一种集合积液槽的货物机械室顶部结构,货物机械室顶部采用普通碳钢板结构,降低了成本;积液槽及其相关构件采用不锈钢结构,以防被低温的液化天然气损伤;采用翅膀结构支撑积液槽,使积液槽和货物机械室结合,节省了材料和空间;在货物机械室甲板上开孔,便于施工人员进行焊接操作。
