Described main thermal-protective coating 4 and time thermal-protective coating 2 are made up of the heat-insulated container 6 and 7 of the multiple parallelepipeds be set up in parallel according to regular pattern.Described heat-insulated container 6 and main heat-insulated container 7 form a kind of surface of substantially flat, and described surface carries described hermetic barrier layers 3 and primary seal blocking layer 5 respectively.
Described heat-insulated container 6 and main heat-insulated container 7 are fixed in described carrier walls 1 by fixed block 8 and 9.Especially, the fixed block 8 of described thermal-protective coating 2 is fixed in carrier walls 1 by pin 10, and described pin 10 is vertically welded to carrier walls 1.As seen from Figure 1, fixed block 8 and 9 is arranged on the corner regions of container 6 and 7.In the same way, the fixed block 8 or 9 being positioned at container corner region can fix four adjacent containers 6 or 7.Other fixed block 8 and 9 is arranged in the center region of container 6 and 7.
Described time hermetic barrier layers 3 is made up of parallel invar strake 11 with primary seal blocking layer 5.These parallel invar strakes 11 are arranged alternately by elongated welding support 13, and described welding support 13 is also invar, and it comprises the edge 12 to the inner bulge of described tank.
Especially, each welding support 13 is forms of invar bar, and it is folded to have L shape cross section.Described welding support 13 is left on the lower floor of thermal-protective coating 2 or 4, and is contained in a sliding manner in groove 15 with the inverted T-shaped formula in the cover plate 14 being provided at container 6 and 7.In the same way, a part for L shape band from T-slot to the inner bulge of described tank, and perpendicular to described carrier walls 1.The raised brim 12 of described invar strake 11 is soldered along welding protuberance 13.
Fig. 2-4 shows the structure of the container 16 for this tank skin.
Container 16 comprises lower panel 17, and it is distributed plate 18 and fixes.At each occurrence, pillar 19 or 23 is adjacent in a row, and is fixed in corresponding distribution grid 18.Especially, often arrange thickness that the pillar 20 of pillar 19 or 23 exceedes container 16 to extend and on direction therefore perpendicular to carrier walls 1.Pillar 20 has a solid rectangular cross section.It is parallel relative to a side 21 of container 16 for often arranging pillar 19 or 23.Number row shore supports one strengthens cover plate 22.Especially, pillar 20 allows the stress propagation being applied to cover plate 22 to wall 1, therefore has the function of resistance against compression.
The pillar 19 and 23 of continuous two rows relative to each other makes up.This is because the pillar 20 of the pillar 19 and 23 of continuous two rows comprises the pillar 20 with identical regular spacing; But two row's pillars 19 and 23 make up mutually in the half spacing in the direction of its length.
The not shown hot insulating lining being filled in the space between pillar 20, can be formed by being such as filled in pillar 20 spaced heat foam or being processed to the foam block be suitable between pillar 20.
Strengthen cover plate 22 and comprise upper plate 24 and lower plate 25, the thickness had separately is 6.5cm.Upper plate 24 and lower plate 25 are separated by series of parallel solid crossbeam 26.Especially, the side 21 that described crossbeam 26 is parallel to container 16 extends.In each situation, crossbeam 26 is set to along and is often arranging on pillar 19 or 23.Crossbeam 26 has rectangular cross section, and its thickness is 6.5cm.Crossbeam 26 is connected in a rigid manner with plate 24,25.This reinforcement cover plate allows the power load distributing of the cover plate being applied to described several pillar due to its rigid element.
Each crossbeam 26 separates with other crossbeams 26, to delimit space between two crossbeams 26 and between plate 24 and 25.These spaces are that the liquid between each bar limit of heat insulating element forms circulation canal.Therefore the allowing side by side of heat-insulated container 16 forms loop at tank skin, and wherein, loop also can introduce inert gas, with in and tank skin, thus to prevent in the presence of oxygen because revealing the blast caused.In addition, so a kind of gas circuit can be used for detecting in hermetic barrier layers 3 and 5 leaking.In order to improve the temperature capacity of described heat-insulated container 16, porous heat-insulating lining can be set at circulation canal.
Fig. 3 and Fig. 4 shows behavior when container is placed in rigid plane, and Fig. 3 and 4 illustrates the load of varying strength respectively.
Fig. 3 is that container 16 stands a schematic side elevation along the load 27 of the little local of centre strut 28, and the base portion of described pillar 20 is fixed.
It should be pointed out that strengthening cover plate 22 in this example there occurs very little deformation.The major component of the pressure 29 of corresponding load is absorbed by centre strut 28.Sub-fraction along the load 30 of described centre strut 28 applying is absorbed by adjacent struts 31, and described adjacent struts 31 is nearest relative to the position of power 27 applying thereon.This is because the rigidity strengthening cover plate 22 and centre strut prevents the distortion of cover plate 22.In this manner, little power (shown in arrow 30) is only had to be absorbed by adjacent pillar 31.
Fig. 4 illustrates that this identical container applies more heavy load 32 along centre strut 28.In this embodiment, centre strut 28 stands great horizontal stress and especially causes bending load.These high-caliber stress cause the slight sedimentation of centre strut 28 and strengthen the slight deformation of cover plate 22.The slight deformation permissible load of this reinforcement cover plate 22 is distributed in adjacent struts 31 better.But because pillar 28 has the rigidity of higher level, sedimentation is still relatively little.Under this mode, be distributed to adjacent struts 31 the distortion of the less degree of panel 22 and load are therefore relatively weak.In addition, be applied to the stress that centre strut 28 is excessive, the breakage of pillar 28 may be caused.
In order to improve the distribution of load in tank skin in Fig. 1, pillar 20 is configured to it and allows to be deposited to larger degree.Particularly, the pillar of primary tank 7 is not superimposed upon on the pillar of time container 6.The advantage of this layout of heat insulation main stor(e)y pillar and time thermal-protective coating, can understand better with reference to Fig. 5 and 6.
The schematic side elevation of Fig. 5 container is listed in such arrangement especially, and described container forms main thermal-protective coating 4 and time thermal-protective coating 2 of tank skin described in Fig. 1.
Especially, it should be noted that container 16 constitutes master's heat insulation stop container 7 of main heat insulation barrier layer 4 and secondary thermal-protective coating comprises time heat-insulated container 6, described time heat-insulated container 6 has the structure different from container 16.
This is because secondary container 6 comprises lower plate 33, upper plate 34 and an insulated lining 35 be disposed between upper plate 34 and lower plate 33.Can find out in the drawings, the stepped setting of pillar 36 extends through insulated lining 35.The stepped setting of pillar 36 is by being connected to upper plate 38 and being formed along the secondary pillar 37 of lower plate 39 terminal of pillar extension.In the mode that the pillar 20 with container 16 is identical, the stepped setting of pillar 36 allows a part of compressive force to be absorbed by tank skin.
It should be pointed out that primary tank 7 is set to adjacent with secondary container 6, under making often kind of situation, row's pillar 19 or 23 is arranged on the centre between two kinds of stepped settings of pillar 36.Especially, main pillar 40 in this embodiment, is positioned in often kind of situation between two pillars 37.
Being provided with like this is beneficial to dispersion better and is applied to the load of pillar.This is because be applied to Fig. 3 and Fig. 4 in a similar fashion, partial load 41 is shown in Figure 5.This partial load 41 is applied on the centre strut 28 of primary tank.Because centre strut is located between time container pillar 36 two kinds of stepped settings, lower plate 17 and upper plate 33 disperse applied pressure by centre strut 28.This resiliently deformable shows the deformation at upper plate 34 and lower plate 17 by line 42 and 43.By this way, centre strut 28 is positioned on elastic surface, and this makes it to be lowered.This motion allows to produce elastic strain to the reinforcement cover plate 22 of pressure that brings of adjacent struts.Line 44 shows the deformation of upper plate 24 and lower plate 25, has its arrow in the region of centre strut 28 towards carrier walls 1 separately.This deformation allows described load to be better scattered in lateral struts, as arrow 45 indicates.
Fig. 6 illustrates identical tank skin, and another advantage of this set of main pillar and time pillar is shown.
This is because Fig. 6 shows the load 46 that tank skin stands to be distributed on multiple pillar.Such load may relate to, and such as, in tank, fluid rocks.This rocking needs a large amount of fluid impact tank skins.
In this case, be similar to Fig. 5, the lower plate 17 of primary tank 7 and the upper plate of time container 6 become the deformation of the pressure initiation of the bridge generation formed by main pillar 40 and time pillar 37.These deformation are illustrated by line 47.Part that therefore these plates 17 and 33 have, has the arrow be directed towards carrier walls between each stepped setting of pillar.The main pillar 40 being positioned at above-mentioned arrow points moves towards carrier walls.In this manner, strengthen cover plate 22 and produce the resiliently deformable similar with plate 17 and 33, as shown in line 48.
These elastic strains of primary tank 7 and time container 6 thus allow the part energy deriving from impact flexibly to be absorbed by tank skin, such as, after shock is movable or weight drops in tank.This energy after an impact, then returns in the mode of vibration damper.
In addition, this set of pillar prevents the punching press, particularly distribution plate 18 and panel that are formed the parts of container by pillar 40 and 37.In addition, this resiliently deformable can prevent pillar 40 and 37 damaged after tank skin is subject to remarkable dynamic stress.By this way, with this set of main pillar 40 and time pillar 37, container 6 and 7 thus serve as " mattress " that decay is applied to the load of tank skin.
Another embodiment of tank skin please refer to Fig. 7.
In this figure, the container 7 of main thermal-protective coating 4 and the container 6 of time thermal-protective coating 2 is only had to be illustrated.It should be pointed out that two thermal-protective coatings 2 and 4 are made up of container 16.Described container 16 superposes in an offset manner.By this way, main pillar 40 and time pillar 140 are not applied.
The position of pillar 40 and 140 is shown in Figure 8.This is because Fig. 8 is the atop part projection of main pillar 40 and time pillar 140 in the plane parallel with tank skin.Merely illustrate nine adjacent pillars 40 and 140 in this embodiment, it corresponds to a part for the pillar of the container 6 and 7 of Fig. 7.
