Description

B-type storage cabin liquid collecting tank capable of limiting

Technical Field

The invention relates to the field of ship construction and design, in particular to a liquid collecting tank arranged on a secondary screen wall of a B-type storage cabin.

Background

A plurality of supporting structures are generally welded at the bottom of a main screen wall of an existing B-type cabin, each supporting structure comprises a secondary screen wall supporting mechanism and a main screen wall limiting mechanism, the steel structure of each supporting structure is welded at the bottom of the main screen wall, a plurality of welding points exist, and a stress concentration area and larger fatigue failure and crack propagation risks exist.

The prior art has been to use the secondary screen wall as a small liquid trap box, which is placed in a region where it does not interfere with the support structure (to avoid placing in the vicinity of the support structure, which could create or enhance stress concentrations during the flight), while introducing leakage liquid into the secondary screen wall via the drainage means.

The problem that this kind of arrange the existence is, to the leakage liquid of main screen wall bottom bearing structure welding point department, need rationally arrange drainage device, ensure that drainage device can successfully dock the welding point department and reveal liquid, will reveal liquid drainage to the secondary screen wall in, drainage device trend is complicated, and is crossing each other very easily, and the work load of local processing is very big, design and construction not convenient for.
