Abstract

The utility model provides an explosion proof carpet including an outer casing(1) and an explosion-proof layer (2), which is characterized in that the explosion-proof layer (2) consists of a basic layer (3), a collecting layer (4) and a strengthened layer (5). The collecting layer (4) is arranged between the basic layer (3) and the strengthened layer (5). And the basic layer (3), the collecting layer (4) and the strengthened layer (5) are all of laminated structure formed by overlapping more than two kinds of bulletproof and explosion-proof material layers phase to phase. The utility model can be used in not only open area, but also plane, cinema and other interior architectures. And when an exploder with 70g TNT or less explodes, people and things 0.5m far away can be prevented from injury effectively.

Description

Explosion-proof blanket

One, technical field:

The utility model relates to a kind of explosive, explosion-protection equipment, especially relates to a kind of explosion-proof blanket.

Two, background technology:

At present, international terrorism and the pernicious case of explosion of domestic terrified crime are in rising trend, national security is taken precautions against department, many public places even general family and individual all might face precipitate explosive incident, and in order to ensure people's life security, existing had explosion-proof blanket to come out.The effect of explosion-proof blanket is used for covering explosive, and when bomb blast, explosion-proof blanket can play and weaken and alleviate explosion wave, shell fragment in the horizontal direction to human body and killing and wounding and damage effect of target on every side.Single, the simple lamination of explosion-proof blanket material therefor, structure on the market is single now, from truly being difficult to prevent after explosive (as the 70-1 type grenade) blast in the horizontal direction injury to the people, explosion-proof blanket is ignited under the effect of blast flame and fuel factor as easy as rolling off a log after the blast, and this type of explosion-proof blanket can only be used for field and can't be used for occasions such as indoor, aircraft, cinema.

Three, summary of the invention:

The utility model provides a kind of can be used for field, can be used for aircraft, cinema and other interior architecture again, and can effectively prevent the explosion-proof blanket that the following explosive explosion time of 70gTNT equivalent makes 0.5m come to harm with people far away.

The technical solution of the utility model is:

A kind of explosion-proof blanket, comprise fire prevention overcoat and explosion-proof layer, it is characterized in that: described explosion-proof layer is made up of basal layer, collecting layer and enhancement Layer, the collecting layer is between basal layer and enhancement Layer, and basal layer, collecting layer and enhancement Layer are the alternate overlapping layer structure that forms of two or more shellproof explosion-proof lamp layers.

The utility model is because ripple is thrown to the space and the distribution situation all around the time is designed to layering, subdivision structure being inflated according to explosion product, and multiple high performance ballistic, explosion-proof lamp organically made up, and alternate overlapping setting, the experiment proved that, do not adding under the situation of any affiliated facility, the explosive hole that uses the back explosion-proof blanket has improved the capability of antidetonance greatly all less than state specified standards.

Four, description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the sectional view of annex arched roof cover in the utility model.

Five, the specific embodiment:

By Fig. 1, Fig. 2 as can be seen, the utility model is made up of fire prevention overcoat 1 and explosion-proof layer 2, it is characterized in that: described explosion-proof layer 2 is made up of basal layer 3, collecting layer 4 and enhancement Layer 5, collecting layer 4 is between basal layer 3 and enhancement Layer 5, and basal layer 3, collecting layer 4 and enhancement Layer 5 are the alternate overlapping layer structure that forms of two or more shellproof explosion-proof lamp layers.

Basal layer 3 is made up of two kinds of shellproof explosion-proof lamp layers of same size in the utility model, and they are by alternate overlapping placement, totally eight layers; Collecting layer 4 is made up of two kinds of shellproof explosion-proof lamp layers of same size, and they are by alternate overlapping placement, totally six layers; Enhancement Layer 5 is formed by three kinds of shellproof explosion-proof lamp plies of same size.

It can also be seen that by Fig. 1, basal layer 3 in the utility model, collecting layer 4 and enhancement Layer are square, and the size dimension size is successively decreased successively, and wherein basal layer 3 is overlapping with the diagonal of collecting layer 4, the diagonal angle at 45 of enhancement Layer 5 and basal layer 3 and collecting layer 4.

Fire prevention overcoat 1 is seamed into an integral body by flameproof fabric, wherein contains three inner bags for pack into basal layer 3, collecting layer 4 and enhancement Layer 5.

Four drift angles at described fire prevention overcoat 1 are provided with fixed band 6, are used for fixing the position of four drift angles on fire prevention overcoat 1 of basal layer 3 and collecting layer 4.

Can also be found out further that by Fig. 3 the utility model also can have an annex arched roof cover 7, arched roof cover 7 is made of several layers super-strength explosion-proof lamp and is archivolt, places the bottom during use, and covers on the explosive.

When finding explosive, the user of service fastens the fixed band clasp that explosion-proof blanket puts outward with both hands, vertical retaining is made blindage in front, (keep certain distance as far as possible near explosive with the chest abdomen, in case explosive explodes at any time), it is covered in above the explosive (should makes explosive be in the explosion-proof blanket centre as far as possible), test with the military grenade of 77-1, explosion-proof blanket central authorities break, form starlike hole in irregular shape, the about 30cm * 30cm of area, periphery turns up, according to GA69-94 explosion-proof blanket national standard: " it is qualified that the hole that the blanket center is blown, aperture are not more than 35cm.

If place its annex arched roof cover in the bottom, and the arched roof cover is covered on the explosive, then can avoid the primary wave of grenade instant of detonation, explosion product more than 95% is collected by the arched roof cover, do not cause explosion-proof blanket to pierce, increase by 0.5 meter with the people far away and the safety of thing, improved its explosive, explosion-proof performance greatly.
