The invention discloses a dual-fuel large container marine LNG fuel tank, and relates to the field of LNG fuel tanks, the dual-fuel large container marine LNG fuel tank comprises an upper fixing frame and a lower fixing frame, the upper fixing frame and the lower fixing frame are detachably installed in a buckled mode, a tank body is arranged on the inner wall of the lower fixing frame, and a fixing seat is arranged on the inner wall of the upper fixing frame and the inner wall of the lower fixing frame in a connected mode. The tank body is placed between the upper fixing frame and the lower fixing frame, the weight of the tank body is borne by the spring steel plate and the lower fixing frame, the spring steel plate can achieve a certain damping effect in the bearing process, and furthermore, a plurality of damping mechanisms are arranged between the upper fixing frame and the lower fixing frame, so that the damping effect is improved. And the damping mechanism is composed of a spring, a fixed shell and a movable rod, the spring can effectively buffer the vibration force on the side face of the tank body, multiple damping of the tank body is achieved through cooperation with a spring steel plate, and the vibration force generated to the tank body in the movement process of the container ship is reduced.
本发明公开了一种双燃料大型集装箱船用LNG燃料罐,涉及LNG燃料罐领域,包括上固定架与下固定架,所述上固定架与下固定架为可拆卸卡扣安装,所述下固定架的内壁设置有罐体,所述上固定架与下固定架的内壁接设置有固定座。本发明通过将罐体放置于上固定架与下固定架之间,罐体的重量由弹簧钢板与下固定架进行承受,而弹簧钢板在承重过程中还可以起到一定的减震作用,进一步的,上固定架与下固定架之间设置有多个减震机构,减震机构由弹簧、固定壳与活动杆组成,弹簧可以有效的将罐体侧面的震动力进行缓冲,配合弹簧钢板实现罐体的多重减震,降低了集装箱船运动过程中对罐体产生的震动力。
