Description

Bullet-proof glass launching breaker for army and police and fire protection

Technical Field

The invention relates to the field of window breaking for army and police and fire protection, in particular to a bullet-proof glass launching breaker for army and police and fire protection.

Background

Bullet-proof glass is a high strength glass that resists gunshot, explosions, and ballistic damage. The rapid breaking and dismantling of the bulletproof glass is urgently needed by the military police and fire protection under special conditions, and the breaking and dismantling tool is convenient, effective, rapid, convenient to carry, safe and reliable and does not depend on gunpowder and air pressure gas as kinetic energy. The company develops the compression strong spring storage force, instantly releases pressure to push the breaking and dismantling rod to irradiate to the special electric breaking and dismantling emitter such as target bulletproof glass, the gunpowder type breaking and dismantling device on the market at present has potential safety hazards of false explosion, and transportation, storage and the like have certain requirements on environmental temperature, and the effective use time is short. The existing window breaker is a four-pipe remote breaking and dismantling system for military police and fire protection, which comprises a breaking and dismantling assembly, a transmitting assembly and a connecting assembly, as disclosed in application number 202021467562.4. The principle of the launching is that after two wires are electrified, electric arcs are generated between two ends of the two wires, which are positioned in the combustion agent bag, so that the combustion agent in the combustion agent bag is ignited, and air in the launching tube, which is positioned between the closing end of the breaking tube and the electronic explosion point bottom plate, is rapidly expanded, so that the columnar tungsten steel structure with the conical pointed end on the breaking tube and the front end of the breaking tube is launched and contacted with an object to be broken, such as toughened glass. Essentially, huge explosion pressure generated by combustion is adopted to push the columnar tungsten steel structure to emit so as to finish the window breaking and working of the toughened glass.

The technical scheme adopted in the existing market is mainly the above, and has the following problems: first, the huge air pressure generated by blasting easily causes bursting of the pipe fitting, which in turn causes serious casualties. Secondly, the requirement on the pipe fitting material of the sleeved columnar tungsten steel structure is higher, so that burst caused by the fact that the pipe fitting cannot bear pressure is avoided. In addition, a certain accidental explosion risk exists in the process of transportation and storage.

In the market, a high-pressure gas cylinder is used as a pneumatic breaking device with kinetic energy, and when the pneumatic breaking device is used, a high-pressure switch is opened, high-pressure gas is sprayed out to push a breaking rod to shoot the target glass to break the toughened glass to a certain thickness. The air pressure of the air storage tank of the emitter is 160 kg, so that the effective kinetic energy of breaking glass can be achieved. The high-pressure glass breaker has unexpected explosion potential safety hazards in the transportation, storage and use processes, and the explosion consequences are serious when the high-pressure gas storage tank falls down accidentally or is broken by collision of other objects in the process of overhigh temperature. The ordinary gas tank can cause the casualties of surrounding people to be severe due to the 8 kg of accidental explosion, and the surrounding people feel frightened. If the accidental explosion destructive power of the gas tank of the 160 kg pressure pneumatic breaking device is twenty times of that of the gas tank, the result of serious casualties is conceivable, so that the defects of the two breaking and tearing transmitters are overcome by our company, an electric high-pressure powerful spring transmitter is developed successfully, 150 mm-thick bulletproof glass can be broken and torn by remote transmission, and the gap of the bulletproof glass breaking technology at home and abroad is filled. The invention scheme and detailed implementation description are presented as follows:
