According to the saddle structure of the B-type liquid cargo tank, the liquid accumulation disc composite structure is added, so that low-temperature damage caused by leakage is avoided; meanwhile, a liquid accumulation disc and a liquid storage disc are used; the tanks are connected, so that secondary pollution is avoided; simultaneously this application's saddle structure simple structure, reasonable in design, greatly reduced the cost.

Description

Saddle structure of B type cargo tank

Technical Field

The utility model relates to a novel saddle structure with a small liquid accumulation disc for a B-type liquid cargo tank, which is suitable for an ultralow-temperature B-type liquid cargo tank saddle area with leakage risk.

Background

The ultra-low temperature B-type liquid cargo tank for the ship is designed according to fatigue fracture mechanics and crack propagation, and the liquid cargo leakage risk exists. After liquid cargo is leaked, the liquid cargo needs to be guided to the secondary shielding and cannot be in direct contact with a nearby ship structure, and low-temperature damage to the accessory ship structure is avoided. The saddle area needs to support the tank body, and belongs to a fatigue analysis key area. And meanwhile, the saddle is directly contacted with the low-temperature tank body and the ship body, and once the tank body leaks, the saddle can directly flow to the bottom ship body structure along the saddle area, so that serious low-temperature damage can be caused.

Among the prior art, the structure that B type cargo tank saddle field adopted is used to the ultra-low temperature ship: multilayer staggered floor processing is made to saddle laminated wood through machine tooling, then arranges on different staggered floors through the insulation construction that closes on, rationally avoids directly revealing, reaches the regional sealed effect of saddle. But laminated wood machining causes higher waste, complex structure and higher cost; meanwhile, the overall design of the saddle is complex.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a saddle structure of a B-type liquid cargo tank, which overcomes the defects in the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the saddle structure of the B-type liquid cargo tank comprises saddle laminated wood arranged on the surface of the B-type liquid cargo tank, wherein a liquid accumulation disc is arranged at the bottom of the saddle laminated wood, and the liquid accumulation disc is welded below the saddle laminated wood.

Preferably, the hydrops dish is hopper-shaped, the hydrops dish bottom is provided with the evacuation mouth, the evacuation mouth is connected with the liquid storage pot pipeline, just be provided with control valve body between evacuation mouth and the liquid storage pot.

Preferably, the upper part of the liquid accumulation disc is provided with an overflow port, and the overflow port is connected with a liquid storage tank pipeline.

Preferably, the edge the hydrops dish center upwards extends and is formed with the support column, support column one end and hydrops dish welded fastening, the other end and saddle laminated wood fixed connection.

Compared with the prior art, the saddle structure of the B-type liquid cargo tank has the advantages that the liquid accumulating disc composite structure is added, so that low-temperature damage caused by leakage is avoided; meanwhile, a liquid accumulation disc and a liquid storage disc are used; the tanks are connected, so that secondary pollution is avoided; simultaneously the saddle structure simple structure of this application, reasonable in design, greatly reduced the cost.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a schematic structural view of a saddle structure of a type B tank according to an embodiment of the present invention;

wherein: 1. a B-type liquid cargo tank; 2. laminating wood for the saddle; 3. a liquid accumulation plate; 301. a support pillar; 302. emptying the air; 303. an overflow port; 4. a liquid storage tank.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1, the saddle structure of the B-type liquid cargo tank comprises saddle laminated wood 2 installed on the surface of the B-type liquid cargo tank 1, wherein a liquid collecting disc 3 is arranged at the bottom of the saddle laminated wood 2, and the liquid collecting disc 3 is welded below the saddle laminated wood 2.

In this solution, the leaked liquid is collected by the liquid collecting tray 3, and the cryogenic protection of the B-type cargo tank 1 is prevented from being damaged.

Preferably, the accumulated liquid disc 3 is funnel-shaped, a drain 302 is arranged at the bottom of the accumulated liquid disc 3, the drain 302 is connected with a liquid storage tank 4 through a pipeline, and a control valve body is arranged between the drain and the liquid storage tank 4.

In this technical scheme, the hourglass liquid dish 3 that leaks can effectual collection, can discharge into liquid storage pot 4 through evacuation mouth 302 with the liquid of collecting simultaneously.

Preferably, the upper part of the liquid accumulation disc 3 is provided with an overflow port 303, and the overflow port 303 is connected with the liquid storage tank 4 through a pipeline.

In this solution, the overflow port 303 prevents the overflow caused by the excessive amount of liquid in the liquid collecting tray 3.

Preferably, a support column 301 extends upwards along the center of the liquid accumulation disc 3, one end of the support column 301 is welded with the liquid accumulation disc 3, and the other end of the support column 301 is fixedly connected with the saddle laminated wood 2.

In the technical scheme, the connection is not limited to the mode of welding the supporting column 301, but can also be realized in a mode of installation.
