Abstract

The utility model discloses a high efficient safety explosion protecting mechanism which comprises an explosion protecting blanket, an outer enclosure and an inner enclosure. The explosion protecting blanket comprises an outer blanket body and an inner blanket body. The inner blanket body is composed of 25 to 35 layers of Dupont aramid fabrics. An explosion protecting hole, the diameter of which is 30 to 40cm, is arranged in the middle of the inner blanket body. The outer blanket body is of a round or a square. The outer blanket body is composed of a lining and an outer skin; the lining is made of 10 to 15 layers of the Dupont aramid fabrics; the outer skin is made of a layer of oxford cloth wrapped outside. The area of an outer blanket body is larger than that of the inner blanket body. The outer blanket body wraps outside the inner blanket body. The outer blanket body is sewn with the inner blanket body tightly. The outer enclosure and the inner enclosure are both of a cylindrical shape. The outer enclosure and the inner enclosure are composed of an inner layer and an outer cladding; the inner layer is made of dozens layers of the Dupont aramid fabrics agglutinated by epoxy resin glue; the outer cladding is wrapped outside. An inner flank of the outer cladding is made of nylon taffeta and the outer flank is made of oxford cloth. The high efficient safety explosion protecting mechanism adapts to be used for covering the explosive to avoid destructive explosion of explosive, and has perfect structure, safe and convenient application, and excellent explosion prevention and safety performance.

Description

The highly effective and safe explosion-protection equipment

Technical field

The utility model belongs to a kind of explosion-protection equipment, and concrete is a kind of explosive that is used to cover, and prevents the device of explosive injury surrounding environment.

Background technology

Prevent the improper blast of explosive,, prevent that the injury to Field Force and facility from being a very important job as eliminating explosive in the explosion-proof activity of anti-terrorism.Along with the development of society, implement the aggravation of terrorist activity and struggle against terror, the explosion-proof work in the middle of anti-terrorism is explosion-proof is also more and more important.At present, when preventing the catastrophic explosion of explosive, generally use a kind of explosion-proof blanket, this explosion-proof blanket has various materials and specification, generally can both play the certain protection effect.But more existing explosion-proof blanket effects also need to improve, and its structure also needs to improve, and makes it more complete.

The utility model content

The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of high safety anti-explosive device, and this apparatus structure is perfect, and is easy to use, and explosion-proof effect and security performance are very good.

The purpose of this utility model is achieved through the following technical solutions: the highly effective and safe explosion-protection equipment is characterized in that: be provided with explosion-proof blanket, outer fence, described explosion-proof blanket is made of outer blanket body and interior blanket body, and interior blanket body is made of 25-35 layer Du Pont aramid fiber cloth; Outer blanket body is rounded or square, area is greater than interior blanket body, blanket is external in wrapping in, be to constitute by 10-15 layer Du Pont aramid fiber cloth internal layer and one deck oxford skin that wraps in the outside, the centre of inside and outside blanket Du Pont aramid fiber layer of cloth is equipped with the explosionproof hole of a diameter 30-40cm, and outer blanket body and interior blanket body closely are sewed together; Described outer fence is cylindrical, the Du Pont's aramid fiber cloth internal layer of making and one deck surrounding layer that wraps in the outside that are bonded together with epoxide-resin glue by the 45-55 layer constitute, the inboard Nylon Taffeta of this surrounding layer, the outside makes of oxford, and user mode is that explosion-proof blanket covers on outer fence.

The utility model further improves and the additional project of enforcement is:

Also be provided with an interior fence in described outer fence the inside, fence is also cylindrical in being somebody's turn to do, constitute with epoxide-resin glue Du Pont's aramid fiber cloth internal layer that is bonded together and one deck surrounding layer that wraps in the outside by the 35-45 layer, the inboard Nylon Taffeta of this surrounding layer, the outside makes of oxford, and its diameter and height are less than outer fence.

The upper edge of the surrounding layer of described outer fence and interior fence is provided with the waterproof zip.

The outer blanket body upper surface of described explosion-proof blanket is fixed with several belts, and this belt is made of the Oxford band.

When the utility model uses, inside and outside fence is buckled on the explosive explosion-proof blanket on the upper cover, detonation of explosives then.Owing to be provided with inside and outside fence, and all be to use the tough and tensile nonflammable lining of multilayer to make, on profile, structure and material, all have very high antiknock, impact resistance; The explosion-proof blanket that is provided with also very strong the preventing of tool explodes to mince and impacts the performance of dispersing, and the centre is provided with interior blanket body, has further strengthened performance, and the centre is provided with explosionproof hole, can discharge air blast well, greatly reduces blast impulse power and destructive power.Therefore, it is complete, easy to use to the utlity model has structure, the explosion-proof and very superior advantage of security performance.
