Inner core is by least two post shell mould thin plate stacks around forming, and the angle that superposes between thin plate is 5-30 degree, and inner core adopts high strength alloy steel.
Urceolus adopts glass fiber compound material.
End cap is spherical, adopt three-decker, comprise the shell of spherical, the inner casing of spherical, end foam aluminium interlayer and end spring, end foam aluminium interlayer is between inner casing and shell, end spring is arranged in end foam aluminium interlayer, one end is fixed on inner casing, and the other end is fixed on shell, and the spacing between end spring is 10cm-30cm; Inner casing adopts high strength alloy steel, and shell adopts glass fiber compound material.
It at the bottom of tank, is spherical, adopt three-decker, comprise the shell of spherical, the inner casing of spherical, end foam aluminium interlayer and end spring, end foam aluminium interlayer is between inner casing and shell, end spring is arranged in end foam aluminium interlayer, one end is fixed on inner casing, and the other end is fixed on shell, and the spacing between end spring is 10cm-30cm; Shell and urceolus are connected as a single entity, and inner casing adopts high strength alloy steel, and shell adopts glass fiber compound material.
End cap is fixed on it anti-explosion tank by padlock.
The inner side of inner core arranges the string bag, and the bottom of the string bag is positioned at the center of can body, guarantees that explosive is in the geometric center blast of can body.
Support adopts universal wheel or is directly fixed on vehicular platform.
The utility model compared with prior art, its remarkable advantage:
1, inner core is by least two post shell mould thin plate stacks around forming, and not one is sealed complete cylindrical shell, can reduce like this reflection overpressure of shock wave, makes inner core be unlikely to occur compared with large plastometric set.Also can effectively stop the impact of the fragment that explodes simultaneously.
2, simultaneously inner core can the form by stress wave pass to aluminium foam sandwich by the energy of shock wave.Aluminium foam sandwich generation plastic deformation, absorbs blast impulse energy, thereby reduces the blast pressure that inner core bears, and has improved the explosion-proof impact capacity of inner core.Through the buffering energy-absorbing function of aluminium foam sandwich, urceolus is in elastic deformation always.
3, urceolus mainly bears hoop tension as calculated, so adopt glass fiber compound material in the situation that meeting tensile strength, can greatly alleviate the quality of tank body.
4, foamed aluminium material density is little, can obviously alleviate the weight of anti-explosion tank, is divided into four, can conveniently assemble and disassemble.
5, elliposoidal end cap adopts three-layer composite structure, and the spherical foamed aluminium of interlayer filling is conveniently replaced.
6, groups of springs also can play buffering energy-absorbing function.The bending plate of four reed-types can be fixed on urceolus, guarantee to recover reset condition after pressure release simultaneously.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model is the anti-explosion tank of the built-in aluminium foam sandwich of post shell group spring, comprises at the bottom of inner core 1, can body aluminium foam sandwich 2, urceolus 3, can body spring 4, end cap 5, tank 12 and support 13.Inner core 1 is by four post shell mould thin plate stacks around forming, and inner core 1 adopts 4 groups of can body springs 4 to be connected with urceolus 3, and can body spring 4 adopts and is threaded with inner core 1 and urceolus 3 respectively, and there is nut constant bearing front and back, and every group of spacing is 20cm.Can body aluminium foam sandwich 2 inserts between can body spring 4.End cap 5 also adopts three-layer composite structure, and inner casing 8 adopts end spring 9 to be connected with shell 6.End foam aluminium interlayer 7 fillers are spherical foamed aluminium, so that change sandwich material, the spacing between end spring 9 is 20cm.The inner casing 8 of end cap 5 covers on one end of inner core 1, both can guarantee sealing under the effect of explosion wave, can realize slippage again.End cap 5 is used padlock 10 to be buckled on cylindrical shell.At the bottom of tank, 12 is spherical, adopt three-layer composite structure, comprise the shell 14 of spherical, the inner casing 8 of spherical, end foam aluminium interlayer 7 and end spring 9, end foam aluminium interlayer 7 is between inner casing 8 and shell 14, end spring 9 is arranged in end foam aluminium interlayer 7, one end is fixed on inner casing 8, and the other end is fixed on shell 14, and the spacing between end spring 9 is 20cm; Shell 14 is connected as a single entity with urceolus 3, and inner casing 8 adopts high strength alloy steel, and shell 14 adopts glass fiber compound material.Inner core is provided with a string bag 11, combustible and explosive articles can be placed in one, and guarantees that it explodes in geometric center, is conducive to like this stable of structure.Urceolus 3 also adopts glass fiber compound material.
Universal wheel 13 is installed at the bottom of tank, is realized moving freely of anti-explosion tank.
When can body aluminium foam sandwich 2 and 7 compressions of end foam aluminium interlayer excessive, can use new foamed aluminium material to replace, urceolus 1 and urceolus 3 and end cap 5 can be reused after assessment.
The utility model can be used for the emergency action of the important public arena combustible and explosive articles such as subway, airport, conference centre.The following TNT equivalent of 1kg can be reused; 1 ~ 3kgTNT equivalent, can guarantee that plastic deformation does not occur inside and outside cylindrical shell, only needs to change aluminium foam sandwich reusable; Maximum safe bearing capacity is 5kgTNT.
