Description
Technical Field
The invention relates to the technical field of ship liquid tanks, in particular to a novel liquid tank structure.
Background
The space of the internal dry tank area of the head and tail area of part of the ship is larger, and the degree of freedom of arrangement of the small liquid tanks is larger. The liquid tank is arranged close to a head tank bulkhead or a tail tank bulkhead, and on one hand, the head tank bulkhead and the tail tank bulkhead are used as a common plane of the liquid tank; on the other hand, these tanks are located close to the nacelle and the hold, which is more advantageous for reducing the length of the turbine piping.
The prior arrangement of the liquid tanks in the area of the first liquid tank has the following disadvantages:
(1) the ribbed flat plate is used as a component bearing lateral pressure and is slightly inferior in bearing efficiency; the flat bulkheads are more prone to buckling and yield failure, and real ships have had examples of buckling failure of fresh water tanks.
(2) Because the total area of the liquid tank boundary is larger, and the liquid tank boundary reinforcing ribs are generally arranged inside the liquid tank, the total area of the coating inside the liquid tank is larger. As a fresh water cabin and a drinking water cabin, the coating causes relatively greater pollution to water quality.
(3) Oil gas in the engine room can easily enter the fresh water cabin and the drinking water cabin.
(4) Since they are located closer to the bulkheads of the leading and trailing cusp compartments, and further away from their volumetric centers, the overall stiffness contribution to both is small.
