Description

Technical Field

[0001] The present invention relates to the technical field of ships, and more specifically, to an anti-rotation structure for a single-ear C-type CO2 tank. Background Art

[0002] For ships using single-ear C-type CO2 tanks, due to the characteristics of their cabin types, whether it is a liquid cargo tank arranged inside the ship's cabin or a fuel tank arranged on the deck, during the sea voyage, due to the influence of ship movement, the tank body will generate a rotational movement or tendency around its own axis. To ensure the safety of the tank body and the ship structure, a structure that can limit its rotational movement needs to be designed. As Figure 4 shown in the currently common method: disconnect the insulating wooden blocks directly below the storage tank, set up a steel structure in the open space and connect it to the storage tank and the saddle below, so as to achieve the purpose of anti-rotation. In this design method, a relatively small construction space will be generated near the insulating wooden blocks in the discontinuous area, resulting in construction difficulties; in addition, the steel structure will form a heat transfer channel between the storage tank and the saddle components, destroying the integrity and airtightness of the adiabatic system, which is not conducive to structural safety.

The inner side is a circle concentric with the tank body wall and is bonded to the tank body wall with glue; the outer side is designed as a straight edge and is bonded to the panel of the ship's saddle with glue;

[0008] Fixed baffles are respectively arranged at both ends of the straight-edge insulating wooden block, and the fixed baffles are directly welded to the tank body wall to further limit the rotational movement of the insulating wooden block relative to the tank body wall;

[0009] The height of the fixed baffle is h1, and the preferred range of h1 is 1 / 3 to 2 / 3 of the thickness of the annular insulating wooden block;

[0011] The hull saddle consists of a saddle web, saddle support brackets, a saddle panel, and a gusset plate;

[0012] The saddle panel matches the outer shape of the special-shaped insulating wooden block, being designed as an arc in the annular insulating wooden block section and as a flat panel at the straight-edge insulating wooden block;

[0013] The saddle web is located in the vertical plane, perpendicular to the saddle panel, and is provided with a plurality of saddle support brackets for strengthening the structure of the saddle;

[0014] Gusset plates are designed on both sides of the saddle panel and are directly welded to the panel structure to limit the movement of the insulating wooden block relative to the saddle structure;

[0015] The height of the gusset plate is h2, and the preferred range of h2 is 1 / 3 to 2 / 3 of the thickness of the annular insulating wooden block;

[0016] In the design scheme of the present invention, by arranging two straight-edge insulating wooden blocks, the rotational movement between the insulating layer and the tank bulkhead is restricted, and at the same time, the rotational movement between the insulating layer and the hull saddle is restricted, thereby restricting the rotational movement between the saddle and the tank.
