Description

A new type of mine-sweeping protective gear

technical field

The invention relates to a personal protective equipment, in particular to a new type of mine-sweeping protective gear.

Background technique

Demining refers to the search and removal of landmines, mines and other explosives. Its purpose is to ensure the freedom of movement of the army and the safety of residents' lives and property, and to restore normal production and living order as soon as possible. The main means of demining in one's own area is manual demining, that is, manually disabling explosives such as landmines, sea mines and unexploded bombs, or removing and destroying them.

Manual demining is the earliest and is still used today as a simple and reliable method of demining, usually implemented by well-trained personnel or teams. Military special work clothes are a kind of protective clothing. They are standard work clothes worn by military personnel when they perform special duties. Their function is to ensure the safety of special service personnel working in an environment harmful to the human body. In order to effectively reduce the injuries caused by accidents in mine-sweeping operations, engineers must be equipped with mine-sweeping protective equipment when performing manual mine-sweeping operations, usually including mine-proof boots, protective helmets and protective suits: the helmet body and the mask are integrated as a head and face. The main body of protection; the top of the mask and the protective suit jointly protect the neck; the top, bottom and lightning protection boots are three independent protection bodies, and the top and bottom jointly protect the chest, crotch, and legs; the bottom and lightning protection The boot joint protects the ankle and foot. Among them, the chest protector in the protective suit is extremely important. However, the chest protector in the existing protective clothing mostly adopts a single integrated bulletproof plate, which has poor cushioning performance and is likely to cause serious damage to the wearer when being impacted by the blast wave. Shock damage.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a new mine-sweeping protective gear, which has excellent cushioning performance and can effectively avoid serious damage to the human body caused by blast waves.

The technical solution adopted by the present invention to solve the technical problem is: a new mine-sweeping protective gear, including a chest protector, the chest protector is composed of an inner buffer layer and an outer explosion-proof layer, and the explosion-proof layer includes a front side In the explosion-proof shell with openings, there are limit plates on both sides of the explosion-proof shell. A deformation space is formed between the limit plate and the side of the explosion-proof shell. The inside of the explosion-proof shell between the two limit plates is provided with first The perforated metal layer, the second perforated metal layer and the push plate, the first perforated metal layer is composed of several perforated metal bodies, and the aperture and porosity of each perforated metal It gradually increases toward both sides, and the pores of each open-hole metal body are filled with liquid resin. The second open-hole metal layer is integrally formed, and the two sides of the push plate are slidably connected to the limit plate.

Preferably, the push plate is composed of an inner push plate and an outer push plate, a shock-absorbing space is left between the inner push plate and the outer push plate, and several reinforcing ribs are also provided between the inner push plate and the outer push plate, and the inner push plate and the outer push plate A plurality of through holes are respectively arranged on the pusher plate.

Preferably, the through holes on the inner push plate and the through holes on the outer push plate are arranged alternately and staggered.

Preferably, the distance between adjacent reinforcing ribs is 1-2 cm.

Preferably, the buffer layer is formed by laminating 3-5 layers of ultra-high molecular weight polyethylene fiber fleece.

Preferably, the liquid resin is liquid rosin resin.

The positive effect of the present invention: firstly, the arrangement of the buffer layer of the present invention has a good protective effect on the human chest, and the ultra-high molecular weight polyethylene fiber fleece used in it has excellent shock-absorbing and explosion-proof performance. Secondly, the present invention adopts a unique explosion-proof layer design, and the double-layer push plate forms a shock-absorbing space, which, combined with the second metal layer with holes, can initially absorb and buffer the blast wave. At the same time, the blast wave pushes the push plate to slide, Squeeze the second perforated metal layer and the first perforated metal layer, the first perforated metal layer deforms and absorbs energy, and at the same time, both sides of the arc-shaped push plate generate side pressure on the limit plate, and the limit plate moves into the deformation space Oblique deformation, the first open metal layer is also deformed when squeezed, and the fluid resin inside is forced out from both sides, so as to absorb and dissolve the energy of the blast wave. In addition, the design of the arc-shaped explosion-proof layer is conducive to the dispersion and transfer of the explosion wave to both sides, and the open-hole metal body in the middle is less likely to be squeezed than the open-hole metal body on both sides due to its relatively small porosity and pore diameter. Therefore, the open-hole metal bodies on both sides are more likely to deform during the impact of the blast wave and increase the arc of the explosion-proof layer, which is more conducive to the dispersion of the blast wave to both sides and greatly reduces the direct impact of the blast wave on the human body. As one of the key points, the present invention fills the pores of the open-pore metal body with fluid resin, which effectively improves the toughness and elastic modulus of the first open-pore metal layer, which is beneficial to the shock absorption of a large amount of blast wave energy. In a word, the present invention adopts a novel and unique structural design, which can provide good explosion-proof protection for the wearer.
