Limitable B-type storage tank liquid collecting tank

Abstract

The invention discloses a limitable B-type storage tank liquid collecting tank, aplurality of limiting pieces are welded to the bottom of a B-type storage bin and on a main screen wall, a downwards-sunken liquid collecting groove is welded to the position, below the limiting pieces, of a body and on a secondary screen wall, the limiting pieces are inserted into the liquid collecting groove and suspended in the liquid collecting groove, first clamping grooves are formed in the two sides of the bottom of each limiting piece, the first laminated wood is inserted into the clamping groove and clamped between the limiting piece and the liquid collecting groove. A second clamping groove is fixed to the outer wall of the liquid collecting groove and corresponds to the first clamping groove in position, a third clamping groove is fixed to the vertical supporting mechanism and corresponds to the second clamping groove in position, and the second laminated wood is clamped between the second clamping groove and the third clamping groove. According to the structure adopted by the invention, through the structural relationship between the liquid collecting tank and the limiting piece, the displacement of the secondary screen wall caused by ship vibration can be effectively limited, the stability of the structure of the secondary screen wall is ensured, and the purposes of avoiding stress concentration and releasing the stress generated by the liquid collecting tank and the limiting piece due to the shrinkage of the secondary screen wall at low temperature can be achieved.

Description

technical field [0001] The invention relates to the field of ship building and design, in particular to a liquid collection tank arranged on a secondary barrier wall of a B-type storage tank. Background technique [0002] The bottom of the main screen wall of the existing B-type cabin is generally welded with multiple support structures. The support structure includes the secondary screen wall support mechanism and the main screen wall limit mechanism. The steel structure of the support structure is welded at the bottom of the main screen wall. There are many welding points and there is stress concentration. area and greater risk of fatigue damage and crack growth. [0003] The existing technology is to use the secondary barrier as a small liquid collection box, and arrange it in the area where it does not interfere with the supporting structure (avoiding the area adjacent to the supporting structure, which will generate or enhance stress concentration during navigation), an...

Problems solved by technology

[0004] The problem with this arrangement is that for the leaked liquid at the welding point of the support structure at the bottom of the main screen wall, it is necessary to arrange the drainage device reasonably to ensure that the drainage device can successfully connect to the leaked liquid at the welding point and drain the leaked liquid into the secondary screen wall. The direction of the drainage device is complicated, and it is easy to cross each other, and the amount of local treatment is huge, which is not convenient for design and construction
