Embodiment
As shown in Figures 1 to 4, the light explosive ordnance disposal helm of the present embodiment, comprise helmet shell 1 and face shield 2, be provided with embedded transparent window 3 on the described face shield 2, described embedded transparent window 3 is fixedly embedded on face shield 2 by screw, described face shield 2 is connected with described helmet shell 1 by rigid structural member 4, described face shield 2 is provided with location and locking device 5 with the junction of described helmet shell 1, slit between described face shield 2 and the described helmet shell 1 is provided with caulking gum 6, described helmet shell 1 inner surface is provided with liner 14 and suspention 12, is provided with camera 7 on the described helmet shell 1, illumination head lamp 8, ventilation duct interface 9, ventilation duct 10, earphone 11 and microphone 13.Described liner 14 is the polystyrene liner, and described liner 14 is cellular with the contact portion of described helmet shell 1.Described suspention 12 is 4 sus-pension settings.The thickness of described liner 14 is 30 millimeters.The total pretective acreage of the described helmet is 0.24 square metre, and weight is 3 kilograms.The thickness of described embedded transparent window 3 is 22 millimeters, and area is 2 square decimeters, and anti-fragmentation performance V50 is 800m./s; Described helmet shell 1 thickness is 9 millimeters, and anti-fragmentation performance V50 is 840m./s; The thickness of described face shield 2 is 9.5 millimeters, and anti-fragmentation performance V50 is 900m./s; The radius of curvature of described embedded transparent window 3 is large, makes the wearer comfortable, reduces dizzy.The outer surface of described helmet shell 1 is provided with carbon fibre material, to increase the intensity of the helmet and face shield.
Described face shield 2 can start or put down by location and the locking device 5 of regulating described helmet shell 1 both sides, and guarantees that the described face shield 2 under two states is fixing.Slit between described face shield 2 and the described helmet shell 1 is tight with the encapsulants such as rubber envelope, effectively stops shock wave to enter inner helmet.The size of described face shield 2 is decided according to the size of described helmet shell 1, tightly cooperates with the size of described helmet shell 1, guarantees the seal protection of wearer's Head And Face and neck front portion.Described liner 14 absorbs the energy of high speed impact, delays the action time of impulsive force, improves the surge guard ability of the helmet.Described liner 14 is cellular with the contact portion of described helmet shell 4, effectively reduces the impulsive force that the helmet is subject to.The set-up mode of described suspention 12 can effectively disperse the weight of described helmet shell 1 and described face shield 2, can adjust according to wearer's head circumference, length, adapts to different size head dummy personnel and wears.
The characteristic value of human body women's head-ornaments three-dimensional dimension data is determined design among the dimension reference standard GB/T 10000-1988 " Chinese adult human dimension " of the described helmet shell 1 of the present embodiment light explosive ordnance disposal helm and the GB/T 2428-1998 " adult's Head Face Dimensions ".The size of described helmet shell 1 is chosen according to adult's head queen size, so that various device is carried in the inside of described helmet shell 1, the inside of described helmet shell 1 is reserved than large space, helps to improve the protective capacities of shock wave.
The light explosive ordnance disposal helm of the present embodiment has following useful technique effect: head and neck that (1) can be the wearer provide protection, reduce to greatest extent the injury that wearer's head is caused because of accidental explosion.(2) possesses good safeguard function, comprehensive protection can be provided wearer's head, except the injury of prevent exploding fragmentation to wearer's head, can also reduce explosion wave to the impact injury of wearer's neck, reduce blast superpressure (negative pressure) to damage and prevent exploding high temperature and high light the burning to eyes, face of the organs such as ear, nose, brain.(3) possess good work efficiency and comfortableness: helmet weight is suitable, and position of centre of gravity is reasonable, and sprung parts system is solid easy, and the inside dimension adjusting device adapts to each size head dummy to be worn, and under various job states, does not affect the visual field and hearing after the helmet is worn; When carrying out explosive operation, the helmet is stable, does not affect motion and various tactical operation; Thermal comfort and contact comfort are good, are conducive to the wearer and keep physical efficiency and lasting work capacity.(4) possess preferably environmental suitability: helmet equipment ventilation equipment, face shield have anti-fog function, can adapt to the explosive job requirements under the various environment.(5) easily carry various device: when satisfying requirement of shelter, can provide the functions such as voice communication, illumination, also can be according to explosive operation needs as carrying platform, the flexible configuration equipment special.(6) provide general protection for wearer's head and neck, and to the without hindrance effect of the proper motion of wearer's head.(7) considered the aspects such as quality, function, protective capacities, comfort level of the helmet, made every effort to design and adapt to the high-level light explosive ordnance disposal helm that domestic explosive is disposed job requirements, met the Chinese visible human biological characteristic.
In some other embodiment, the thickness of described helmet shell 1 can be any number between the 6-12 millimeter, and the thickness of described face shield 2 can be any number between the 6-12 millimeter; The thickness of described embedded transparent window 3 can be any number between the 10-30 millimeter, and area can be any number between the 1.5-2.5 square decimeter; Described liner 14 can be combination layer or polypropylene liner or the nylon inner lining of polystyrene liner or polyurethane kind liner or polystyrene liner and the formation of polyurethane kind liner; The thickness of described liner 14 can be any number between the 10-50 millimeter; All can realize goal of the invention of the present invention.Described helmet shell 1 and described face shield 2 main parts are all made of high performance fibre material, especially adopt the little superhigh molecular weight polyethylene fibers layer of density and polyparaphenylene's benzo twoport oxazole fibrage, under the condition that can guarantee the anti-fragmentation function admirable of the helmet, reduce to greatest extent helmet gross weight, reduce the wearer's head sense of discomfort that causes owing to the weight reason; Outside carbon coated fibrous material is to increase the intensity of described helmet shell 1 and described face shield 2.
