Shaking stopping device for B-type enclosure system of large-scale LNG ship

Abstract

The invention relates to a shaking stopping device for a B-type enclosure system of a large-scale LNG ship. The shaking stopping device arranged above the enclosure system is characterized by comprising a lower retainer ring, a laminating flitch arranged in the lower retainer ring, and an upper baffle wedged in the upper part of the laminating flitch, wherein a metallic material is embedded in the laminating flitch; the upper baffle comprises an upper toggle plate and an upper panel; the lower retainer ring comprises a lower toggle plate and a lower panel; a first gap is formed between each of the two lateral sides of the upper part of the laminating flitch and the upper toggle plate; a second gap is formed between each of the left side and the right side of the bottom of the laminating flitch and the lower toggle plate; a third gap is formed between the bottom of the laminating flitch and the lower panel; a fourth gap is formed between each of the front side and rear sides of the laminating flitch and the lower toggle plate; stopping laminating wooden wedge blocks are respectively embedded in the first gap and the second gap, and low temperature resistant epoxy resins are poured in the third gap and the fourth gap. Through the adoption of the shaking stopping device for the B-type enclosure system of the large-scale LNG ship, disclosed by the invention, the structure is simple, the manufacturing is convenient, the situation that liquid cargoes on the ship are evaporated does not occur, the low temperature resistance is good, and the shaking stopping device has a high practical value.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an anti-sway device for a B-type containment system of a large LNG ship. Background technique [0002] The new "Type B" containment system of large LNG ships is characterized by an independent self-supporting containment system, the bottom of which is supported by a support, and there is no other structural connection between the containment system and the hull components. When the hull rolls, the containment system must Lateral shaking will also occur and relative to the hull, which will cause damage to the structure of the containment system, and will cause further sloshing of the liquid cargo, increasing the evaporation rate of the liquid cargo. [0003] Therefore, a anti-sway device that can overcome the above-mentioned shortcomings, has a simple structure, is convenient to manufacture, does not cause evaporation of liquid cargo on board, and has good low-temperature performance i...
