发烟型增程防暴枪榴弹Smoke-type extended-range anti-riot grenade

技术领域technical field

本实用新型涉及防暴弹技术领域，具体为发烟型增程防暴枪榴弹。The utility model relates to the technical field of anti-riot bombs, in particular to a fuming type extended-range anti-riot grenade.

背景技术Background technique

发烟弹也叫烟幕弹，战时用于生成烟幕，迷盲和干扰对方的观察、射击和指示目标，平时在演习行动中可以营造战场氛围，在日常训练中因不产生刺激性烟雾，可作为催泪弹的训练弹使用。发烟弹按投射方式可分为枪发发烟弹、手投发烟弹和发射器发射式发烟弹三种类型，发烟弹按成烟原理可分为爆炸型和升华型两种类型。爆炸型发烟弹弹体内装黄磷或易挥发的液体发烟剂。装有黄磷的发烟弹爆炸时，爆管将弹体炸裂，黄磷被分散到大气中与氧燃烧生成五氧化二磷形成烟幕。装有液体发烟剂的发烟弹，其发烟剂则吸收大气中水分形成烟幕。升华型发烟弹弹体内装有粗蒽、六氯乙烷或有色发烟剂，在投放后点燃，从发烟孔喷出而成烟幕。其中枪发发烟弹升华型居多，枪发的爆炸型发烟弹存在潜在的炸膛危险；手投发烟弹既有升华型也有爆炸型，但投掷距离均过短，手投爆炸型发烟弹则存在易炸手等安全隐患；发射器发射式发烟弹也是升华型居多，采用电底火发射，保存需要防静电。因此，如何解决现有枪发爆炸型发烟弹容易炸膛，手投发烟弹投掷距离过短的问题成为困扰学术界和军警部门的重大难题。Smoke bombs are also called smoke screen bombs. They are used to generate smoke screens during wartime, blind and interfere with each other's observation, shooting, and target indication. They can create a battlefield atmosphere during exercises in peacetime. Because they do not produce irritating smoke in daily training, they can be used as a smoke bomb. Tear gas training rounds are used. According to the projection method, the smoke bombs can be divided into three types: gun-fired smoke bombs, hand-thrown smoke bombs and launcher-fired smoke bombs. . Explosive smoke bombs are filled with yellow phosphorus or volatile liquid smoke agent. When the smoke bomb containing yellow phosphorus explodes, the burst tube will burst the bomb body, and the yellow phosphorus will be dispersed into the atmosphere and burned with oxygen to form phosphorus pentoxide to form a smoke screen. The smoke bomb is equipped with liquid smoking agent, and its smoke agent absorbs moisture in the atmosphere to form a smoke screen. The sublimation type smoke bomb is filled with crude anthracene, hexachloroethane or colored smoke agent, which is ignited after being put in, and is sprayed from the smoke hole to form a smoke screen. Among them, most of the gun-fired smoke bombs are sublimated, and the explosive-type smoke bombs fired by guns have potential danger of explosion; hand-thrown smoke bombs have both sublimation and explosive types, but the throwing distance is too short. The pods have potential safety hazards such as being easy to blow hands; most of the pods fired by the launcher are sublimation types, which are launched by electric primer, and need to be protected against static electricity for storage. Therefore, how to solve the problem that the existing gun-fired explosive smoke bombs are easy to explode and the throwing distance of hand-thrown smoke bombs is too short has become a major problem that plagues the academic circles and the military and police departments.

The delay time of 1 s of the primary delayed ignition tube 14 corresponds to the primary propulsion process of the present invention, and the delay time of 4 s of the secondary delayed ignition tube 8 corresponds to the secondary propulsion process of the present invention.

如图1所示，所述冲击钢珠17的直径略大于钢珠导轨16的内径，使得在平常的储存、运输等环节中，因抵靠牢固，不会出现冲击钢珠17意外击发后火帽15的情形，同时在正常发射时缓冲器18受子弹收集器19的撞击，能顺利将冲击钢珠17快速挤入钢珠导轨16，并完成对后火帽15的高速击发。As shown in FIG. 1 , the diameter of the impact steel ball 17 is slightly larger than the inner diameter of the steel ball guide rail 16, so that in ordinary storage, transportation and other links, due to the firm abutment, there will be no accidental firing of the impact steel ball 17. At the same time, when the buffer 18 is hit by the bullet collector 19 during normal firing, the impact steel ball 17 can be quickly squeezed into the steel ball guide 16 smoothly, and the high-speed firing of the rear fire cap 15 can be completed.

本实施例中，所述尾管13受子弹冲击动能和自动步枪枪管火药燃气作用，实现一次推进，一次推进距离为100米；所述推进剂腔9内装的推进剂10燃烧产生高温燃气喷射助推，实现二次推进，二次推进距离为400米。In this embodiment, the tail pipe 13 is affected by the impact kinetic energy of the bullet and the gunpowder gas of the automatic rifle barrel to achieve one push, and the distance of one push is 100 meters; the propellant 10 in the propellant cavity 9 is burned to generate high-temperature gas injection Boost, achieve secondary propulsion, and the secondary propulsion distance is 400 meters.

工作原理：working principle:

使用本实用新型时，将尾管13套在自动步枪枪管上，关闭自动步枪导气孔，将保险置于单发位置，扣动扳机，发射一发实弹，子弹弹头撞击子弹收集器19，并被子弹收集器19收集，子弹弹头动能和自动步枪火药燃气推力转化为子弹收集器19的冲击力，子弹收集器19撞击缓冲器18，缓冲器18撞击冲击钢珠17，迫使其挤入钢珠导轨16，同时，冲击钢珠17完成对后火帽15 的快速击发，子弹弹头飞行动能和自动步枪火药燃气推力转化为本实用新型的飞行动能，视为对本实用新型的一次推动，一次推进距离约为100米。随后，后火帽15点燃一级延期点火管14内，一级延期点火管14经过1s的延期时间后，点燃推进剂腔9内的推进剂10，推进剂10猛烈燃烧产生大量高温高压火药燃气，火药燃气烧蚀尾喷口11内的热熔胶，从尾喷口11高速喷出，实现对本实用新型的二次推动，二次推进距离约为400米，推进剂10燃烧产生的燃气同时点燃二级延期管8，二级延期管8经过4s的延期时间后，点燃抛射药腔7-1内的抛射药7-2，抛射药7-2猛烈燃烧，产生高温高压燃气，使得抛射药腔7-1的压力升高，推盘7-3边沿的热熔胶被烧蚀，在压力作用下，推盘7-3带动撞针7-4快速撞击前火帽6，同时推盘7-3推动发烟罐4，迫使发烟罐4冲破风帽1，飞离弹体7，在此过程中，前火帽6点燃高压管2内的引燃药3，引燃药3燃烧产生的燃气烧蚀泄压孔2-1内的热熔胶，点然发烟剂 5，促使发烟剂5猛烈燃烧，烧蚀斜形发烟孔4-1和直形发烟孔4-2内的热熔胶，大量烟雾从斜形发烟孔4-1和直形发烟孔4-2内高速喷出，实现500米距离开外的烟雾迷盲。由于斜形发烟孔4-1的设计，发烟罐4着地后会出现不规则窜动，不易被捡起转移。When using the utility model, the tail pipe 13 is set on the barrel of the automatic rifle, the air guide hole of the automatic rifle is closed, the safety is placed in the single-shot position, the trigger is pulled, a live ammunition is fired, and the bullet hits the bullet collector 19, and Collected by the bullet collector 19, the kinetic energy of the bullet warhead and the thrust of the automatic rifle gunpowder gas are converted into the impact force of the bullet collector 19, the bullet collector 19 hits the buffer 18, and the buffer 18 hits the impact steel ball 17, forcing it to squeeze into the steel ball guide 16 At the same time, the impact steel ball 17 completes the rapid firing of the rear flash cap 15, and the flying kinetic energy of the bullet warhead and the automatic rifle gunpowder gas thrust are converted into the flying kinetic energy of the present utility model, which is regarded as a push to the present utility model, and a propelling distance is about 100 Meter. Subsequently, the rear cap 15 ignites the first-stage delayed ignition tube 14, and after the delay time of 1 s, the first-stage delayed ignition tube 14 ignites the propellant 10 in the propellant cavity 9, and the propellant 10 burns violently to generate a large amount of high-temperature and high-pressure gunpowder gas , the hot melt glue in the tail nozzle 11 is ablated by the gunpowder gas, and ejected from the tail nozzle 11 at a high speed to realize the secondary push of the present utility model. The first stage delay tube 8 and the second stage delay tube 8 ignite the propellant 7-2 in the propellant chamber 7-1 after the delay time of 4s. The pressure of -1 increases, and the hot melt adhesive on the edge of the push plate 7-3 is ablated. Under the action of the pressure, the push plate 7-3 drives the striker 7-4 to quickly hit the front flash cap 6, and at the same time the push plate 7-3 pushes The smoke canister 4 forces the smoke canister 4 to break through the hood 1 and fly away from the projectile 7. During this process, the front fire cap 6 ignites the pilot charge 3 in the high-pressure pipe 2, and the combustion of the pilot charge 3 produces gas ablation. The hot melt adhesive in the pressure relief hole 2-1 ignites the smoking agent 5, which causes the smoking agent 5 to burn violently, and ablate the hot melt in the oblique smoking hole 4-1 and the straight smoking hole 4-2. Glue, a large amount of smoke is ejected from the oblique smoke hole 4-1 and the straight smoke hole 4-2 at a high speed, realizing smoke blindness at a distance of 500 meters. Due to the design of the oblique smoking hole 4-1, the smoking can 4 will move irregularly after it hits the ground, and it is not easy to be picked up and transferred.
