Abstract
The utility model relates to a double bottom structure of a liquid cargo tank, including an upper base board and a lower base board, which are arranged with an interval. A plurality of parallel main rib plates and a plurality of parallel bottom girders arranged with intervals are arranged with intervals between the upper base board and the lower base board. The bottom girders and the main rib plates are arranged perpendicularly with each other. The double bottom structure is characterized in that the bottom girders are welded with transverse toggle plates, and the transverse toggle plates on the adjacent bottom girders are arranged oppositely with intervals. Compared with the prior art, the declinate transverse toggle plates of the double bottom structure of the liquid cargo tank provided by the utility model can not only increase the intensity of the double bottom structure, but also effectively reduce the shaking of the ballast water in the double bottom and improve the stability of ships, and can reduce the speed of leakage, extend the leakage time, be conducive to the emergency processing of oil tanker damage accidents, and help to win time for rescue and salvation in the burst accidents of liquid cargo tank shell partly damaged or broken.
Description
Technical field
The utility model relates to ship structure, specifically refers to a kind of boats and ships cargo tank double bottom structure.
Background technology
Cargo tank exists when boats and ships move because of damage leaks and causes the huge safety and the risk of pollution.The safety of the bilge structure influence cargo tank of cargo tank.When the cabin cabinet loaded liquid goods, there was huge potential safety hazard in the cabin cabinet wall particularly bilge under the effect of external and internal pressure, and is high to material requirements.And when cargo tank generation damage leaked, liquid goods can directly leak to out of my cabin, caused gross pollution.Simultaneously, holes can strengthen along with leaking further.Therefore there is the people propose the leakage that double bottom structure prevents cargo tank.Double bottom structure comprises the upper plate of steel and the lower shoe of steel; Upper plate and lower shoe are provided with at interval; Between upper plate and lower shoe, be interval with the bottom boom that the polylith main floor that is parallel to each other and polylith parallel interval are provided with, described bottom boom is vertical each other with main floor.
The cargo tank of double bottom structure has improved structural rigidity and safety greatly, but when boats and ships load ballast water, can produce huge rocking, and still has the risk of cargo tank damage.
Summary of the invention
The utility model technical matters to be solved is to prior art, provides a kind of and can be reduced in that boats and ships when loading ballast water rock and the cargo tank double bottom structure of stored liquid goods leakage rate can reduce the cargo tank damage time.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this cargo tank double bottom structure; Comprise the upper plate and the lower shoe that are provided with at interval; Be interval with the bottom boom that main floor that polylith is parallel to each other and polylith parallel interval are provided with between said upper plate and the lower shoe; Described bottom boom and main floor vertical setting each other it is characterized in that being welded with horizontal bracket on the described bottom boom, and the horizontal bracket subtend on the adjacent bottom boom are provided with at interval.
Preferably, described horizontal bracket is obliquely installed to said lower shoe direction from the position of being welded.
As preferably, adjacent horizontal bracket is that center line is symmetrical set with both center lines.
Compared with prior art, the horizontal bracket that has a down dip that the cargo tank double bottom structure that the utility model provided increases can also effectively reduce rocking of the interior ballast water of double bottom except the intensity that can increase double bottom structure, improve the stability of boats and ships; In the burst accident of damage of cargo tank shell part or breakage, the speed that can reduce to leak prolongs leak time, helps the emergency handling of oil carrier damage accident simultaneously, and relief gains time in order to speedily carry out rescue work.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment (local structure).
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this cargo tank double bottom structure comprises:
Comprise the upper plate 1 and lower shoe 2 that are provided with at interval; Be interval with the bottom boom 4 that main floor 3 that polylith is parallel to each other and polylith polylith parallel interval are provided with between upper plate 1 and the lower shoe 2; And bottom boom 4 and main floor 3 mutual vertical settings; Be welded with horizontal bracket 5 on the bottom boom 4, adjacent horizontal bracket 5 is that center line is symmetrical set with both center lines.Horizontal bracket is obliquely installed to the lower shoe direction from the position of being welded in the present embodiment.The horizontal bracket 5 that has a down dip can also effectively reduce rocking of the interior ballast water of double bottom except the intensity that can increase double bottom structure, improve the stability of boats and ships; In the burst accident of damage of cargo tank part or breakage, the speed that can reduce to leak prolongs leak time, helps the emergency handling of oil carrier damage accident simultaneously, and relief gains time in order to speedily carry out rescue work.
Claims (3)
1. cargo tank double bottom structure; Comprise the upper plate and the lower shoe that are provided with at interval; Be interval with the bottom boom that main floor that polylith is parallel to each other and polylith polylith parallel interval are provided with between said upper plate and the lower shoe; Described bottom boom and main floor vertical setting each other it is characterized in that being welded with horizontal bracket on the described bottom boom, and adjacent horizontal bracket subtend are provided with at interval.
2. cargo tank double bottom structure according to claim 1 is characterized in that described horizontal bracket is obliquely installed to said lower shoe direction from the position of being welded.
