Embodiment 1

[0038] Example 1: A composite material explosion-proof box is composed of three parts: inner box 1, outer box 2 and parcel bag 3, see figure 1 shown.

[0039] Wherein, the inner box 1 is a drawer-like structure, which adopts a box-shaped structure with an open upper end, and each wall of the inner box 1 is composed of three-layer structure, which are respectively the inner box flame-retardant layer 11 and the inner box main protective layer 12 from the inside to the outside. And inner box waterproof layer 13, refer to figure 2 shown.

[0040] Wherein, the outer box 2 is a drawer-like structure, adopting a hexahedral box-shaped structure with side openings, and from the inside to the outside are the outer box flame-retardant layer 21, the outer box main protective layer 22, and the outer box waterproof layer 23, see image 3 shown.

[0041] Wherein, the wrapping bag 3 is a flexible cylindrical structure, which respectively includes a wrapping bag flame-retardant layer 31...

Embodiment 2

[0048] Example 2: The package bag 3 in the implementation example 1 is not changed, and the explosion impact bearing surfaces of the inner box 1 and the outer box 2 in the implementation example are strengthened. Specifically, the following measures are adopted: the bottom of the inner box 1 (not shown in the figure) is padded with a high-strength fiber board with the same shape and size as the bottom of the inner box 1, and the surface density of the high-strength fiber board is 8~10kg / m 2 ; On the inner wall (not shown) of the outer box 2 corresponding to the opening surface of the inner box 1, the high-strength fiber composite board with the same shape and size as the inner wall of the outer box 2 is compositely produced, and the surface density of the high-strength fiber composite board is 8~10kg / m 2 .

[0049] In this implementation example, 200g standard TNT explosives are placed in the geometric center of the inner case 1, then the inner case 1 is received into the...

Embodiment 3

[0051] Example 3: The inner box 1 in the implementation example 1 is not changed, and an electromagnetic shielding layer (not shown in the figure) is added to the exposed surfaces of the wrapping bag 3 and the outer box 2 in the implementation example. The electromagnetic shielding layer can use materials such as surface-coated film shielding materials, filled composite shielding materials, conductive coating-type shielding materials, or nanometer shielding materials.

Abstract

The invention provides a composite material explosion-proof box which comprises an inner box, an outer box and a parcel bag, wherein the inner box is a drawer-shaped structure; the outer box is a drawer cabinet-shaped structure; and the parcel bag is a flexible cylindrical structure. When the composite material explosion-proof box is in a carried transportation state, the parcel bag is folded andthen accommodated in the inner box, and the inner box is accommodated in the outer box so as to obtain good portable mobility; and when the composite material explosion-proof box is in a stored transportation state, a suspected explosive is accommodated in the inner box, the inner box is accommodated in the outer box, and the outer box is accommodated in the parcel bag so as to obtain omnibearingprotection. Compared with the prior art, the invention provides the composite material explosion-proof box which has the advantages of small size, light weight, all-sided protection and no secondary killing and is suitable for occasions with limited spaces, such as airplane passenger cabins, motor train carriages, offices, and the like.

Description

technical field [0001] The invention belongs to the field of explosion protection, and relates to an explosion-proof container, in particular to a light-weight, non-secondary damage-free, high-strength composite material explosion-proof box suitable for limited spaces such as aircraft cabins, train compartments, and offices. Background technique [0002] Explosion-proof container is a professional equipment used for temporary storage or transportation of explosives that can suppress the lethal effect of shock waves and fragments produced by explosives on the surrounding environment. At present, the commonly used explosion-proof containers are mainly explosion-proof tanks, explosion-proof balls, explosion-proof boxes, explosion-proof fences and explosion-proof blankets and other products. Explosion-proof tanks are mostly open type, and the upper side is used for venting, which is easy to cause greater damage to the upper (lower) tank body, and has higher noise and greater imp...
