Abstract

A foamed metal sandwich explosion-weakening anti-explosion jar comprises a jar body 3. Foamed metal 4 is filled between an inner panel 1 and an outer panel 2 of the jar body 3. Explosives are moved into the jar body 3 with a mechanical arm, then the jar body 3 is transported to a safe area and finally the explosives are taken out and destroyed by burning. If explosion happens during the transportation process, the inner panel 1 of the jar body 3 and the foamed metal 4 can be compressed and deformed together to absorb explosion energy; the outer panel 2 can constrain the deformation of the inner panel 1 and the foamed metal 4; and while decaying, explosive blast wave is released upwards from the open mouth of the jar to take effect in the protection of surrounding people and facilities. The jar is characterized by simple structure and high safety.

Description

The weak quick-fried anti-explosion tank of a kind of foam metal sandwich

Technical field

The utility model relates to a kind of anti-terrorism anti-explosion tank, the weak quick-fried anti-explosion tank of particularly a kind of foam metal sandwich.

Background technology

Foam metal has the platform stress higher than high molecular polymer, so energy absorption characteristics is excellent more, and this new structural material is used to energy absorption in a lot of fields.Anti-explosion tank is a critical facility of safeguarding public safety, traditional anti-explosion tank is generally entity steel construction or MULTILAYER COMPOSITE sandwich structure, the tank body quality of entity steel construction is big, too heavy, and the MULTILAYER COMPOSITE sandwich structure often adopts materials such as buffered fiber, sandy soil, steel pipe, PVC plate, high molecular polymerization foam as the sandwich filler, the antiknock ability relatively a little less than.

Summary of the invention

In order to overcome the defective of above-mentioned prior art; the novel purpose of this use is to provide a kind of contactless foam metal sandwich weak quick-fried anti-explosion tank; adopt the laminboard layer of closed-cell aluminum foam as anti-explosion tank; absorb energy by the compression under the blast load; personnel and facility around the protection; and the capability of antidetonance is better than traditional composite multi-layer structure anti-explosion tank, has characteristics simple in structure, that security performance is high.

For for achieving the above object, the design that the utility model adopts is: the weak quick-fried anti-explosion tank of a kind of foam metal sandwich, comprise a tank body 3, and be filled with foam metal 4 between the wainscot 1 of tank body 3 and the outer panels 2.

The thickness of described outer panels 2 is greater than the thickness of wainscot 1.

Described foam metal 4 is foamed aluminium, foam aluminium alloy or blister steel.

Because the energy absorption characteristics of foam metal 4, use it for antiknock energy-absorbing field, when the design anti-explosion tank, as the tank body sandwich, can absorb a large amount of explosion energies, compare, significantly reduction is being arranged qualitatively with traditional entity anti-explosion tank, and compare with traditional MULTILAYER COMPOSITE anti-explosion tank, on the antiknock ability, be greatly improved again.

Description of drawings

Fig. 1 is a structure principle chart of the present utility model.

Fig. 2 is a vertical view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model and operation principle are done and to be described in detail.

With reference to accompanying drawing, the weak quick-fried anti-explosion tank of a kind of foam metal sandwich comprises a tank body 3, is filled with foam metal 4 between the wainscot 1 of tank body 3 and the outer panels 2, and the thickness 2 of outer panels is greater than the thickness of wainscot 1, so that the constraint sandwich makes its compression fully.

Operation principle of the present utility model is: explosive is moved in the tank body 3 with mechanical arm, tank body 3 is transported to the safety area takes out destruction; In the process of transporting; if blast; wainscot 1 meeting and together compression of foam metal 4 of tank body 3; absorb explosion energy; the distortion of outer panels 2 constraints wainscot 1 and foam metal 4; explosion wave is discharged up by the jar mouth that opens wide in decay, can protect the effect of personnel's facility on every side. and the utility model can become the antiknock device of department's anti-terrorism special uses such as public security.
