Definitions
- Liquid ⁇ projectile, projection device and delivery method thereof
- the invention relates to a fire-fighting equipment, in particular to a device capable of high-rise fire extinguishing, dangerous places, grassland and forest remote fire extinguishing, and an ecological protection equipment, especially equipment for soil and water conservation and vegetation restoration in arid areas, It is a liquid projectile and its projection device and delivery method.
- the fire truck uses a high-pressure pump to spray water from the high-pressure water dragon.
- the water column is gradually torn and dispersed by the air during the flight, so no matter how to increase the power of the water pump, only 80 can be realized.
- the height of the jet around the meter, and the current high-rise building is more than 100 meters, even reaching two or three hundred meters, which greatly exceeds the range of the high-pressure water dragon of the existing fire truck, although the fire-fighting medium used by it - water, is very Convenient, but the high-pressure water dragon is far from meeting the current fire protection requirements;
- fire-fighting devices such as the "rocket fire-fighting bomb" disclosed in CN2183551Y, which put the fire-extinguishing agent in the fire extinguisher and then use the rocket to Fire field, which can achieve long-distance fire extinguishing.
- gunpowder because of the use of gunpowder in such devices, it is a "fire” and is strictly regulated. It has high requirements for storage and transportation, and requires special professional operators. Such equipment also generally has the drawback of being expensive, and thus it is difficult to widely spread the application.
- the "Pneumatic Fire Cannon” disclosed in CN2234285Y and the “Supported Pneumatic Fire Extinguisher” disclosed by CN1765432A have proposed a technical solution for remotely delivering fire extinguishing bombs by using compressed air, which significantly improves the safety of operation.
- the launching of such devices is basically a single pipe plus manual, the launching speed is slow, and the degree of automation is low.
- the fire extinguishing bombs delivered by such devices are still filled with fire extinguishing agent as a fire extinguishing medium, and the maintenance and use thereof are strict, and once the fire extinguishing agent is damp, Expired failure will lose the function of fire extinguishing, and the price of fire extinguishing bombs is also relatively expensive.
- the projection device using compressed air has a very limited amount of bombs, and the fire is still not extinguished. The fire extinguishing bombs are used up. Therefore, the applicability is also greatly limited.
- the existing fire-fighting equipment can directly apply water for fire extinguishing, although it is easy to achieve local According to the material, but can not really achieve long-distance delivery; the existing fire-fighting bombs can be delivered very far, but because of the use of fire-extinguishing agents as a fire-fighting medium, there is a general need for maintenance, failure, limited amount of bombs, expensive, etc. Defects, correspondingly, existing remote fire-extinguishing devices also have defects such as the inability to process fire-fighting bombs on site.
- the market urgently needs a projection device with a long range, large or substantially unloaded capacity, better economy, better applicability, high degree of automation, and more reliable single-use projection devices and corresponding fire-fighting bombs.
- the liquid projectile of the present invention is realized in that it comprises a cartridge case, characterized in that the cartridge case is filled with a functional liquid, and the cartridge case is made of a flexible or hard material which is easily impacted and broken.
- the rupturable flexible material comprises a plastic film, a metal foil, a paper or a composite material of at least two of the above materials, and the hard material which is susceptible to impact cracking comprises a hard paper shell, a plastic or a composite material of the two.
- the functional liquid includes water, alcohol, fuel oil, and a mixture of water and an extinguishing agent, fertilizer or medicament.
- Water can be above-ground water and groundwater, including common surface water bodies such as rivers, rivers, lakes, seas, ponds and reservoirs. It also includes well water, tap water, fire water, etc., which are taken from underground water.
- the flexible or hard material constituting the bullet casing which is easily impact-broken is a flame-retardant material, or a casing made of a flexible or hard material which is easily impacted and broken is subjected to a flame-retardant treatment.
- the specific method of the flame-retardant treatment may be various, and the flame-retardant material layer may be disposed on the surface of the shell by using a paste, spray, or the like, or may be pre-soaked by the flame-retardant liquid.
- the flexible or hard material constituting the bullet casing which is easy to impact and rupture adopts an environmentally friendly material which can achieve rapid natural degradation.
- the tail shell is prevented from being damaged during the launching process, and the push base can be arranged on the shell.
- a stabilizer wing or/and a fairing may be disposed on the bullet casing.
- the fairing is disposed at the front end of the shell
- the stabilizing wing is disposed at the tail or the middle rear portion of the casing, wherein the stabilizing wing needs to be foldable when the stabilizer is disposed at the rear of the casing. Due to the provision of the stabilizing wing, the liquid projecting bomb of the present invention may not rotate or rotate along the longitudinal axis of the projectile during the flight after the projection.
- At least two chambers along the axial direction of the elastic shell may be disposed in the elastic shell.
- the chambers are completely independent or partially penetrated from one another.
- a casing rupture inducing device may be disposed on the casing or inside the casing to ensure that after the liquid projecting bomb of the present invention is delivered to the target ground, the casing may be broken by the impact to dissipate the internal functional liquid.
- the shell rupture inducing device may be a crack or a sharp object disposed on the shell shell or inside the shell; the shell rupture inducing device may also be at least one partial weak region disposed on the shell shell.
- the push housing may be disposed on at least a part of the outer surface of the outer casing.
- the push housing can be arranged in various ways. For example, it can be disposed on the bottom and part of the side of the shell, or on the bottom and all sides of the shell. In application, it can be selected according to actual needs.

Description
一种液^:射弹及其投射装置和投送方法 技术械
本发明涉及一种消防器材,尤其是一种可以用于高楼灭火、危险场所、 草原和 森林远程灭火的器材, 以及一种生态保护器材, 尤其是在干旱地区水土保持和植 被恢复的器材, 具体为一种液体投射弹及其投射装置和投送方法。
背景技术
近年来, 随着国民经济的不断快速发展, 人们的日常生产生活对消防工作提 出了越来越高的要求, 特别是油田、 油库、 森林、 草原、 高层建筑等场所, 一旦 发生火灾都火势迅猛, 人员不易靠近, 因此, 远距离灭火装置、 高射程灭火装置 成为急需的消防装备。
现有远距离灭火装置中, 消防车利用高压泵将水从高压水龙喷射而出, 水柱 在飞行过程中会被空气逐渐撕裂而分散落地, 因此无论如何提高水泵的功率, 也 只能实现 80米左右的喷射高度, 而目前的高层建筑动辄百米以上, 甚至达到二、 三百米, 大大超出了现有消防车的高压水龙的射程, 虽然其使用的灭火工质—— 水, 取材十分方便, 但高压水龙已远不能满足当前的消防要求; 此外, 市面上还 出现了诸如 CN2183551Y公开的"火箭灭火弹"的消防装置, 此类装置将灭火剂装 在灭火器中, 再利用火箭弹 至火场, 从而可以实现远距离灭火, 但是, 由于 此类装置中使用火药, 属于"火品", 受到严格管制, 其对于贮运、 发射都有较高 的要求, 需要特别专业的操作人员, 而且此类装备还普遍存在价格昂贵的缺陷, 因此难以大范围普及应用。
针对上述问题, CN2234285Y公开的 "气压消防炮 "和 CN1765432A公开的 "支 架式气动灭火炮"等专利中又提出了利用压缩空气远程投送灭火弹的技术方案,显 着提高了操作的安全性, 但是此类装置发射基本是单管加手动, 发射速度慢, 自 动化程度低, 尤其是此类装置投送的灭火弹中仍然是装填灭火剂作为灭火工质, 其维护使用严格, 灭火剂一旦受潮、 过期失效将失去灭火的功能, 灭火弹价格也 较为昂贵, 特别是野外作业时, 此类利用压缩空气的投射装置自身带弹量也十分 有限, 往往火还没有朴灭, 灭火弹就用完了, 因此适用性也大大受到限制。
综上可以看出, 利用现有消防装备直接应用水进行灭火, 虽然容易实现就地
取材, 但无法真正实现远距离投送; 现有的灭火弹虽然可以投送的很远, 但由于 采用灭火剂作为灭火工质, 又普遍存在需要维护、 会失效、 弹量有限、 价格昂贵 等缺陷, 相应的, 现有远程灭火装置也存在着不能现场加工灭火弹等缺陷。 市场 迫切需要一种射程远、 载弹量大或基本不受限制、 经济性更好, 适用性更好, 自 动化程度高, 应用更筒单可靠的投射装置及相应的灭火弹。
另一方面, 随着全球气候变暖恶化, 我国干旱地区的很多山坡、 荒地、 草原水土 流失和贫瘠化严重, 无法涵养森林草地, 吸纳緩释雨水, 结果是下雨发洪水、 旱 季黄枯秃,现有灌溉设备最大射程也只有 30米左右,无法将水或含肥料的水肥投 送抛洒到更远处; 靠人工运水时, 没有道路或山高路险时, 非常辛苦和危险。 在 灭虫和卫生防疫方面, 另外除了飞机播撒雾化的液体药剂外, 目前没有一种能够 远程(例如投送距离大于 100米) 为森林和草原抛洒农药的装备, 以及远程投射 抛洒液体防疫药剂的装备, 因此市场也急需一种能将水、 水肥或液体药剂投送抛 洒到远处、 草原、、 荒地、 沙漠或山坡上的生态保护设备和方法。
发明内容
为了克服上述缺陷, 本发明的目的之一在于提供一种易于取材并且适于进行 远程投送的液体投射弹。
本发明液体投射弹是这样实现的, 包括弹壳, 其特征在于弹壳内装有功能液 体, 弹壳由易撞击破裂的柔性或硬质材料制成。
所述易撞击破裂的柔性材料包括塑料膜、 金属箔、 纸或以上材料中至少二种 的复合材料, 易撞击破裂的硬质材料包括硬纸壳、 塑料或二者的复合材料。
所述功能液体包括水, 酒精, 燃油, 以及水与灭火剂、 肥料或者药剂的的混 合液。 水可以是地上水、 地下水, 包括了江、 河、 湖、 海、 池塘和水库等常见地 表水体, 也包括了井水、 自来水、 消防用水等取自于地下的水体。
优选的, 构成弹壳的易撞击破裂的柔性或硬质材料为阻燃材料, 或者易撞击 破裂的柔性或硬质材料制成的弹壳经过阻燃处理。 所述阻燃处理的具体方式可以 多种多样, 其可以是在弹壳表面利用粘贴、 喷涂等工艺设置阻燃材料层, 或者是 利用阻燃液体对弹壳进行预浸泡处理等。 此外, 出于环保的需要, 优选的, 构成 弹壳的易撞击破裂的柔性或硬质材料采用可以实现快速自然降解的环保材料。
为了便于进行远程投送, 防止弹壳在发射过程中尾部受力破损, 可以在弹壳 上设置推送底座。 此外, 为了保证本发明液体投射弹在投射过程中飞行稳定、 飞 行阻力小, 还可以在弹壳上设置稳定翼或 /和整流罩。 所述整流罩设置在弹壳前端
部, 稳定翼设置在弹壳的尾部或中后部, 其中, 当稳定翼设置在弹壳中后部时, 稳定翼需可折叠。 由于设置了稳定翼,本发明液体投射弹在投射后的飞行过程中, 液体投射弹沿弹体纵轴可以不旋转, 也可以旋转。 对于采用旋转姿态飞行的本发 明液体投射弹, 为保证投射过程中液体投射弹内部的功能液体随弹壳一起旋转, 从而保持姿态稳定, 可以在弹壳内设置至少两个沿弹壳轴向的腔室, 腔室间彼此 完全独立或局部贯通。另外,还可以在弹壳上或弹壳内部设置弹壳破裂诱发装置, 以保证本发明液体投射弹在投送至目标地后, 弹壳受到撞击会破裂从而将内部的 功能液体散出。 所述弹壳破裂诱发装置可以是弹壳壳体上或弹壳内部设置的脆裂 物或尖锐物;弹壳破裂诱发装置还可以为弹壳壳体上设置的至少一处局部薄弱区。
本发明液体投射弹中, 还可以在弹壳外部至少局部表面设置推送外壳。 所述 推送外壳的设置方式多种多样, 例如, 其可以设置在弹壳的底部及部分侧面上, 也可以设置在弹壳的底部及全部侧面上,在应用时,可以根据实际需要进行选择。
弹壳或推送外壳的外表面还可以设置减阻耐磨层。 所述减阻耐磨层由低摩擦 系数材料构成,例如可以采用特富龙材料等。 此外, 弹壳或推送外壳的外表面上还 可以设置压力平衡槽, 压力平衡槽设有向弹壳尾部开放的豁口。 由于弹壳或推送 外壳的外表面增设了压力平衡槽, 当本发明液体投射弹装入投射管后, 压力平衡 槽与投射管管壁一起构成气室, 气室与投射腔连通, 当液体投射弹在气体压力推 动下沿投射腔移动过程中, 气室减小了液体投射弹与投射管管壁的接触面积, 气 室中的空气还可以起到润滑作用, 能够有效避免液体投射弹在发射过程中意外破 损导致的弹壳中存储的功能液体提前散出。
本发明的第二个目的在于提供一种应用上面所述液体投射弹的投射装置, 其包括压缩气源、 投射开关和投射管, 投射管尾部设有投射腔, 其特征在于还包 括功能液体源、 弹体包装装置、 储弹箱、 送弹装置和蓄压调节罐, 功能液体源提 供功能液体, 弹体包装装置将功能液体源提供的功能液体包装成液体投射弹, 包 装好的液体投射弹储存于储弹箱内, 蓄压调节罐设有压力调节装置, 蓄压调节罐 通过投射开关与投射腔连通。
为了提高投射效率, 投射管数量可以超过一根, 将所有投射管平行排列成一 排、 两排或两排以上, 构成投射管组。 投射管分成至少两组, 每组包括至少一根 投射管, 每组投射管共用一个投射开关, 各组投射开关之间设有延时开启机构, 每个投射开关均设有自动关闭机构, 上一个投射开关的自动关闭机构与下一个投 射开关的延时开启机构联动, 这样就可以实现每组投射管的依次投射, 避免多组
投射管同时发射时, 蓄压调节罐压力消耗过大, 需要频繁地补压, 不容易保持压 力稳定导致液体投射弹偏离目标的问题。 此外也可以减轻发射时所产生的后座力 对本发明投射装置的影响。 为避免液体投射弹在投射管内损坏, 构成投射管组的 每根投射管的投射腔内还可以分别设有推送座管, 相应的投射管内还设有推送座 管复位机构, 投射时液体投射弹装填在推送座管内。 另外, 参照现有炮弹的装填 机构, 送弹装置可以采用上压入式、 侧压入式、 旋转压入式或后膛压入式。 还可 以在投射管的前端设置弹体出膛传感作动装置,投射开关设有自动关闭机构,弹体 出膛传感作动装置包括光电传感器或压力传感器, 弹体出膛传感作动装置引发自 动关闭机构动作关闭投射开关, 或 /和引发送弹装置开启投射腔。
由于本发明投射装置所应用的液体投射弹的弹壳采用易撞击破裂的材料制 成, 因此为了防止液体投射弹自投射管射出的过程中, 投射管管腔侧壁不光滑而 擦伤弹壳, 可以在投射管的管腔内设置低摩擦阻力材料构成的村套或镀膜, 所述 低摩擦阻力材料包括尼龙材料、 PVC材料、 氟化石墨烯材料、 特氟龙材料或可用 于电镀的金属材料等, 所述可用于电镀的金属材料包括辞、 镍、 铬等; 基于同样 的考虑, 当投射管的管腔内表面设置逐渐旋转的滑膛槽时, 滑膛槽的所有凹凸表 面应均为圓滑表面。
此外, 为了避免在液体投射弹离开投射管的瞬间, 由于压力急剧变化导致弹 壳发生强烈变形造成的弹壳破损, 可以在投射管上设置泄压装置, 以调节液体投 射弹离开投射管时的压力变化。 所述泄压装置的具体形式可以多种多样, 例如, 所述泄压装置可以是投射管上设置的泄压阀; 或者是投射管靠近出口端设置扩张 段, 扩张段的管腔直径由内端向外端逐渐增大; 或者是投射管在靠近其出口端设 置的泄压段, 泄压段的管壁上设有多个泄压通孔, 泄压段的长度大于液体投射弹 的长度。
所述弹体包装装置包括进料管、 计量装置、 进料开关、 弹壳夹持装置、 弹壳 开启装置和弹壳封闭装置, 另外, 弹体包装装置中还可以包括真空吸附装置。
由于本发明投射装置中包含了功能液体源, 利用弹体包装装置可以随时对液 体投射弹进行批量生产, 特别是由于本发明液体投射弹的十分易于就地取材, 因 此也可以在有水的地方就地进行生产,减少运输环节,非常适于野外大批量投射。 为更好地实现大批量投射的目的, 本发明投射装置中还可以包括压缩气源, 其中 蓄压调节罐与压缩气源相连, 压力调节装置设置在蓄压调节罐与压缩气源之间。 所述压力调节装置包括与蓄压调节罐连通的压力传感器和调压阀, 调压阀包含关
闭、 降压和增压三种功能阀或三种阀位状态。 经压力传感器检测, 蓄压调节罐内 的压力达到要求时调压阀自动关闭, 需降压时通过调压阀将蓄压调节罐与大气连 通泄压, 需增压时通过调压阀将蓄压调节罐与压缩气源连通增压。
为了提高投射精度, 投射管上还可以设有瞄准系统。 所述瞄准系统包括激光 测距仪、 光学瞄准仪、 仰角测量仪、 转角测量仪中的至少一种, 此外还包括转角 调节机构或 /和仰角调节机构。瞄准系统中还可以包括气象感知系统和弹道计算系 统, 气象感知系统包括风速计、 风向仪、 气压计、 温度计中的至少一种, 气象感 知系统的测量结果输入弹道计算系统,进而计算出投射压力和投射管组瞄准参数。 为了进一步提高投射的精确度, 本发明投射装置中还可以包括弹着点人工修正装 置或弹着点自动修正装置。
为了提高机动性、 便于瞄准, 本发明投射装置还可以包括旋转底盘、 固定底 盘和卡车, 旋转底盘可以相对于固定底盘转动, 至少送弹装置、 投射管、 蓄压调 节罐放置在旋转底盘上, 固定底盘牢固设置在卡车上, 组成投射车, 投射车设有 液压稳定支腿。 此外, 也可以将功能液体源、 弹体包装装置、 储弹箱设置在另一 辆卡车上, 组成弹体包装车, 可以到远处功能液体源处(例如水塘)进行弹体包 装生产, 利用弹体包装车与投射车配合, 将弹体包装车上包装好的液体投射弹储 存于储弹箱内, 再提供给投射车实施投送, 有利于进一步提高液体投射弹的生产 供应能力和远程投送能力。
本发明中功能液体源可以为储液罐或 /和液体输送泵。根据不同的用途, 本发 明投射装置在制造液体投射弹之前, 有时还需要在储液罐的水中混入灭火剂、 肥 料或农药等添加材料, 为了使添加材料混合均匀, 还可以在储液罐中设置搅拌装 置。
本发明的第三个目的在于提供一种应用所述投射装置投送液体投射弹的方 法,其特征在于包括以下步骤:
1 )利用弹体包装装置将功能液体源提供的功能液体的包装在弹壳内, 制成液 体投射弹;
2 )将液体投射弹存放在储弹箱内;
3 )根据射程将投射装置稳定放置于目标地附近;
4 )利用送弹装置将储弹箱内的液体投射弹装填到投射管的投射腔内, 封闭投 射腔;
5 )确定投射参数, 瞄准目标;
6 )根据投射参数, 利用压力调节装置精确调节蓄压调节罐的压力, 使蓄压调 节罐的压力达到设定的投射压力;
7 )开启投射开关使蓄压调节罐与投射腔连通, 蓄压调节罐内的高压气体进入 投射腔, 将投射腔内的液体投射弹推射出投射管, 在液体投射弹即将射出投射 筒的瞬间, 关闭投射开关;
8 )在投射过程中根据实际弹着点修正投射管的水平转角、 仰角或投射压力;
9 )利用送弹装置将下一轮液体投射弹装填到投射管中, 进行下一轮投射。 本发明应用投射装置投送液体投射弹的方法中, 当投射装置中的投射管超过 一根时, 对于不同的投射管组, 可以利用不同投射开关的延时开启机构及自动关 闭机构相互联动配合, 实现不同投射管组依次投射液体投射弹。
本发明液体投射弹, 主要利用各种易于获取的水作为功能液体, 容易实现就 地取材, 成本低, 不存在过期失效的风险, 经济可靠, 实用性好, 适用性强。 另 外根据用途不同, 还可以在水中混入灭火剂、 肥料或药剂等材料, 可以大大拓展 本发明液体投射弹的使用功能。
本发明投射装置利用压缩空气作为动力, 可以实现安全地远程投送, 特别是 本发明投射装置中设有弹体包装装置,可以实现液体投射弹的加工和投送全流程, 具有安全、 高效、 环保、 大投射量等优点, 其适用性和实用性都显着提高。 本发 明利用投射装置投送液体投射弹的方法, 操作方便, 安全实用。
由于本发明液体投射弹中的功能液体主要是水, 因此,基于所述的投送方法, 利用本发明投射装置投送液体投射弹, 不仅可以实现高层建筑、 森林、 油田等场 所的高射程或远程灭火, 还可以实现许多其他功能。 例如, 可以用于沙化地区的 生态恢复或緩解荒山、 草场的旱情, 具体操作时, 只需要将利用投射装置将本发 明液体投射弹直接投送到荒山、 草场或沙化地区即可; 也可以用于某些维持秩序 的场合的驱离制止, 如违法示威、 哄抢、 街头打斗等; 将本发明投射装置装配在 船上, 还可以用于实现朴灭水上船舶、 海上作业平台、 岸边工厂等场所的火灾, 当然, 也可以用于驱离海盗, 或用于驱离非法进入领海的船只的一般性执法。 此 夕卜, 还可以用于防治森林或草原的病虫害, 或是用于为草木追肥等。 根据要实现 的目的不同, 本发明液体投射弹中的功能液体还可以是混有灭火剂、 肥料或药剂 的水, 其实现的专用效果更好。 另外, 本发明液体投射弹中还可以设置酒精或燃 油等其他功能液体, 以实现不同的功能。 例如, 向疫区投射装有酒精作为功能液 体的液体投射弹, 可以实现远距离消毒作业, 当然也可以利用其他防疫药剂混入
水中作为消毒防疫使用; 利用装有燃油作为功能液体的液体投射弹, 可以安全快 速地实现垦荒作业。
在本发明的研究初期, 研究人员普遍认为, 如果液体投射弹的弹壳很厚, 投 射后不易破裂, 则失去了预期的功能; 如果液体投射弹的弹壳很薄, 虽然投射后 更容易破裂, 但是也容易在发射阶段在投射管内就爆裂。 这是因为, 为了达到较 远的射程, 本发明投射装置的投射压力通常达 0.3 ~ lMpa, 即 3 ~ 10个大气压, 理论上, 一个直径 120mm, 长 600mm,重 4.5千克的液体投射弹要承受 670千克 的推力。 乍一想, "弹壳是无法承受这么高的压力的", 要实现 "投射管内不破、 落 地时容易破"是不容易的。 经过发明人反复实验, 采用一些相应措施, 如液体投射 弹采用硬质材料的弹壳、 或在弹壳底部增设推送底座、 或在投射管内设置推送座 管都可以有效避免液体投射弹在发射阶段于投射管内发生爆裂。 最后, 经过仔细 分析和反复实验还发现, 即使采用较薄的柔性材料制成的弹壳也能避免液体投射 弹在投射阶段于投射管内发生爆裂。 其原理是: 在推送阶段,投射推力虽然很高, 达到数百千克, 但在液体投射弹的轴向, 投射推力与液体投射弹的惯性反力相平 衡, 液体投射弹在弹壳底部的压力内外平衡; 在弹壳侧面又有投射管管腔内表面 支承, 如果管腔内表面光滑, 也不会破裂; 在液体投射弹前端, 惯性反力产生的 压力是向后和径向的, 液体投射弹的柔性弹壳在前后方向的压力也是大致内外平 衡的, 只有径向压力不平衡, 但总量不大。 综上所述, 在投射过程中, 3 ~ 10 个 大气压的"投射气压"并非完全由液体投射弹的弹壳承受, 因此也不易爆裂。 但在 液体投射弹部分离开投射管出口的瞬间, 液体投射弹前后的压力瞬间失衡, 弹壳 易发生爆裂,需要采取特别措施给予控制。这也是本发明投射装置的技术方案中, 需要在投射管上设置泄压装置的原因所在。
综上所述, 本发明液体投射弹及其投射装置, 经济实用, 操作筒便, 本发明 利用投射装置投送液体投射弹的方法, 筒单易行, 投送效率高, 市场应用前景十 分广阔。

具体实施方式
实施例一
如图 1和图 2所示本发明液体投射弹, 包括弹壳 1 , 弹壳 1由塑料膜制成, 弹壳 1内设置功能液体, 功能液体为水 2。 其中, 弹壳 1前端用金属卡 81扎紧封 闭, 弹壳 1尾端设有进料通道 4, 进料通道 4靠近弹壳 1尾端利用热封合口 3给 予封闭, 保证弹壳 1中的水 2不会漏出。 此外, 为了便于进行远程投送, 防止本 发明液体投射弹的弹壳 1在投射过程中尾部受力破损, 在弹壳 1尾端还设有推送 底座 29。
需要指出的是, 由于本例所述液体投射弹的弹壳 1由柔性的塑料膜制成, 其 厚度较薄, 因此与推送底座 29装配后, 热封合口 3会折弯与弹壳底部贴合, 不会 占用很多推送底座 29内的空间, 此外, 推送底座 29的壁厚实际也较薄, 图 1与 图 2仅为了便于表示和说明液体投射弹的各部分结构,其对弹壳 1和推送底座 29 的壁厚及热封合口 3与推送底座 29的实际配合状态等均未作详实的反映,仅为示 意, 特此说明。
本发明液体投射弹的制造和投送由投射装置来实现。 如图 3、 图 4、 图 5和 图 6所示本发明投射装置, 包括压缩气源 50、 投射开关 7和投射管 8, 投射管 8 设有多根,按三排四列布置并利用框架 16支撑构成投射管组,投射管 8上设有泄 压装置, 泄压装置为投射管 8在靠近其出口端设置的泄压段, 泄压段的管壁上设 有多个泄压通孔 84, 泄压段的长度大于液体投射弹的长度, 泄压通孔与投射管内 壁圓滑过渡。 投射管 8尾部设有投射腔 25, 投射管 8上还设有瞄准系统, 此外还 包括储液罐 9构成的功能液体源、 弹体包装装置 10、 储弹箱 11、 送弹装置 12和 蓄压调节罐 5。 储液罐 9内装有功能液体——水, 弹体包装装置 10将储液罐内的 功能液体包装成液体投射弹, 包装好的液体投射弹储存于储弹箱 11 内, 储弹箱 11与送弹装置 12相连, 蓄压调节罐 5通过管路 27及投射开关 7与投射腔 25连 通, 蓄压调节罐 5设有压力调节装置 6, 压力调节装置 6设置在压缩气源 50与蓄 压调节罐 5之间。为满足大批量投送的需要,所述压缩气源 50为一大功率空气压 缩机。 所述瞄准系统, 包括瞄准具(未具体示出)及仰角调节机构, 仰角调节机 构包括框架 16下方设置的一个固定长度的后支脚 13 , 此外还有一个可以通过螺 杆 14及支座 15调节整体高度的前支脚。 每个投射管 8对应设置一个投射开关 7
进行控制, 此外,每个投射开关 7都设有自动关闭机构, 开关时间的设置原则是: 在液体投射弹前端即将离开投射管时, 关闭投射开关。 相邻投射开关 7之间设有 延时开启机构, 上一个投射开关的自动关闭机构与下一个投射开关的延时开启机 构联动, 通过不同投射开关的延时开启机构及自动关闭机构相互联动配合, 实现 不同投射管组依次投射液体投射弹。 由于带有自动开闭控制功能及延时控制的电 磁阀在现有技术中十分常见, 因此本文中不对投射开关结构作过多说明。
特别要说明的是, 本发明液体投射弹中, 推送底座 29 为圓柱形, 其套设在 弹壳尾端。为保证在投射管内投射过程中不泄压,一方面推送底座 29的外径尺寸 应与投射管内径严格对应,另一方面推送底座 29优先采用弹性聚氨脂、弹性橡胶 等具有一定弹性的材料制成,以便于与投射管侧壁形成密封,推送底座 29应比液 体投射弹壳体刚硬。 此外, 在附图中为表示清楚, 管路 27画的较细, 在实际应用 中, 为提供足够的推力, 管路 27的直径 ^艮粗。
压力调节装置 6包括与蓄压调节罐连通的压力传感器和调压阀 (图中未具体 示出), 调压阀包含关闭、 降压和增压三种阀位状态。 根据射程确定蓄压调节罐 5 的输出压力后,通过压力调节装置 6对蓄压调节罐 5中的气体压力进行精确调节。 具体调节过程如下: 经压力传感器检测, 蓄压调节罐 5中的压力达到要求时压力 调节装置 6中的调压阀自动关闭, 需降压时通过调压阀将蓄压调节罐 5与大气连 通泄压, 需增压时通过调压阀将蓄压调节罐 5与压缩气源 50连通增压。 当然,基 于上述原理, 压力调节装置 6中的调压阀也可以是包含关闭、 降压和增压三种功 能阀的组合, 也能实现同样的效果。 另外, 需要说明的是, 作为一种特例, 由于 有些高端品牌的大功率空气压缩机自身就带有较大容量的气包并配有压力稳定系 统, 例如英格索兰品牌的大型空压机等, 如果采用此类空压机作为本发明投射装 置的压缩气源 50使用, 也可以不再额外设置压力调节装置 6和蓄压调节罐 5 , 此 类空压机即可视为本发明技术方案中所提到的压力调节装置 6、 蓄压调节罐 5及 压缩气源 50的集成。本段文字记录的技术内容适用于本发明投射装置的所有技术 方案, 在此一并给予说明。
需要指出的是, 投射管 8在靠近其出口端的局部管壁上设置泄压段, 应保证 液体投射弹前端到达投射管出口处时,至少部分泄压通孔 84已经与外部空间保持 连通,这样才能保证投射管内的气体逐渐泄压, 当液体投射弹前端脱离投射管时, 液体投射弹的弹壳已能承受业已泄压的管内气压。 通过在投射管上设置泄压段, 可以有效避免投射过程中液体投射弹部分露出投射管时, 液体投射弹底部承受投
射高压, 而前端仅承受大气压, 巨大的压差容易引发弹壳爆裂的问题。 为实现上 下面结合图 5具体说明利用本发明投射装置制造液体投射弹的过程。 作为功 能液体的水储存在储液罐 9中, 当需要制造液体投射弹时, 本发明投射装置中的 弹体包装装置开始工作, 所述弹体包装装置包括进料管 17、 计量装置、 进料开关 19、 弹壳夹持装置 23、 弹壳开启装置 20、 弹壳封闭装置和真空吸附装置 32。 其 中, 计量装置由流量控制计 18、 信号控制装置 82和进料开关 19构成, 弹壳封闭 装置具体由热封合装置 22和切断装置 21组成, 热封合装置的工作原理与现有热 封口机的工作原理相同。 弹体包装装置的具体工作原理如下, 首先, 将一端已由 金属卡扎紧的半成品弹壳送至灌注工位,弹壳开启装置 20将弹壳 1的进料通道 4 撑开, 弹壳开启装置上设置的吹风孔向弹壳 1的腔室内送风使其内部腔室张开, 同时弹壳夹持装置 23从外部托持着整个被气体扩张后的弹壳; 然后, 储液罐 9 中的水经进料管 17进入弹体包装装置中,水经过计量装置的计量后,沿撑开的进 料通道 4灌入弹壳 1中, 当通过流量控制计 18的水达到设定的流体体积时,弹壳 1中已经灌满了水, 信号控制装置 82动作, 进料开关 19关闭, 停止向弹壳 1中 灌注水; 接着, 热封合装置 22动作, 将进料通道 4封闭, 再利用切断装置 21将 多余的弹壳部分裁切掉, 制成半成品液体投射弹 24, 弹壳夹持装置 23将半成品 液体投射弹夹持运送至下一工位, 在该工位设有真空吸附装置 32, 利用真空吸附 装置 32将推送底座 29运送并装配在半成品液体投射弹尾部, 完成一个本发明液 体投射弹的制造, 制造好的液体投射弹被放入储弹箱中, 按照上述流程弹体包装 装置开始制造下一个液体投射弹。
要说明的是, 在实际应用中, 可以采用一端已由金属卡扎紧的、 单个的半成 品弹壳用于本发明液体投射弹的制造; 也可以在本发明投射装置的弹体包装装置 中增设一个实施金属卡扎紧动作制造半成品弹壳的工位, 这样就可以利用塑料膜 管料带进行连续生产, 只需要在前一个液体投射弹的进料通道被热封合装置 22 封合后,在封合部位上方利用金属卡扎紧,然后利用切断装置 21在封合部位与金 属卡扎紧位置之间切断, 这样将已灌注功能液体的半成品液体投射弹转至下一工 位,下端被金属卡扎紧的塑料膜料带进入灌注工位,与弹壳夹持装置 23及弹壳开 启装置 20配合进行灌注功能液体作业。由于上述灌装作业的工作原理与现有粗火 腿及袋装液态食品的自动包装设备的工作原理基本相同, 在此不再作详细的附图 说明, 都在本发明要求的保护范围内。 当然, 本发明液体投射弹也可以采取两端
全用金属卡扎紧的结构, 也在本发明要求的保护范围之中。
下面结合图 1 ~图 6说明应用本发明投射装置投送液体投射弹的过程如下: ( 1 )利用弹体包装装置将水这种易取材的功能液体包装在弹壳 1内,制成液体投 射弹 24; ( 2 )将制好的液体投射弹 24存放在投射装置的储弹箱 11内; ( 3 )确定 投射目标, 根据射程将投射装置稳定安置于投射目标附近; ( 4 )利用送弹装置 12 将储弹箱 11内的液体投射弹 24装填到各个投射管 8的投射腔 25内并封闭投射腔, 液体投射弹 24在限位挡环 26的帮助下位于投射腔下部, 并与投射腔末端面保持 一定的距离, 如图 6所示; (5 )利用瞄准系统瞄准目标并确定投射参数; (6 )根 据参数, 利用压力调节装置 6精确调节蓄压调节罐 5的压力, 使蓄压调节罐 5的 压力达到设定的投射压力; (7 )如图 3和图 6所示, 启动第一支投射管 8对应的 投射开关 7, 使蓄压调节罐 5与第一支投射管 8的投射腔 25连通, 高压气体进入 第一支投射管的投射腔, 将投射腔内的液体投射弹 24推射出投射管 8, 在液体投 射弹尾端进入泄压段之时, 第一支投射管 8对应的投射开关 7关闭, 第二支投射 管 8对应的投射开关开启, 按本步骤前述说明将后续投射管 8中的液体投射弹依 次延时投射出去,投射弹到达目标后, 触地破裂, 功能液体分洒于大片面积; (8 ) 在投射过程中根据弹着点修正投射管 8的水平转角、 仰角或投射压力; (9 )利用 送弹装置 12将下一组液体投射弹 24分别装填到各投射管 8中,进行下一轮发射。
由于在液体投射弹的弹壳 1上增设推送底座 29,投送过程中液体投射弹的意 外损坏更少, 投送效果更好, 效率更高, 实用性也更强。 需要说明的是, 本发明 液体投射弹, 弹壳可以由易撞击破裂的柔性或硬质材料制成, 除了已经提到的塑 料膜以外, 所述易撞击破裂的柔性材料还包括纸、 金属箔或这三类材料中至少二 种的复合材料等其他材料, 此外, 可以用于制造弹壳的易撞击破裂的硬质材料包 括硬纸壳、 塑料或二者的复合材料。 这些材料都可以用于加工弹壳, 只要撞击后 可以破裂, 都可以实现相似的效果。此外, 本发明投射装置中的送弹装置 12的装 弹方式可以采用上压入式、 侧压入式、 旋转压入式或后膛压入式, 在现有送弹装 置中都有类似应用, 不再——附图说明。
本发明液体投射弹, 应用水这种功能液体, 容易实现就地取材, 成本低, 不 存在过期失效的风险, 经济可靠。 本发明投射装置利用压缩空气作为动力, 可以 安全地实现远程投送, 特别是本发明投射装置中设有弹体包装装置, 可以实现加 工和投送液体投射弹的全流程, 具有安全、 高效、 环保、 大投射量等优点, 其适 用性和实用性都显着提高。 本发明利用投射装置投送液体投射弹的方法, 筒单易
行, 操作方便。 由于本发明液体投射弹中采用水这种功能液体, 并且弹壳由易撞 击破裂的柔性或硬质材料制成, 在与地面或地表物体碰撞后, 弹壳会瞬间破裂, 将弹壳中设置的水四散开来。 尤其重要的是, 一般的水龙采用喷射原理, 水柱在 飞行过程中被空气撕裂雾化, 提前散落在地, 射程最多只能达 80米高, 150多米 远, 而本发明将功能液体包装在弹壳内, 避免了功能液体的雾化, 因此除了空气 阻力损耗外, 液体投射弹基本遵循抛物运动规律到达目标, 射高可以达到 200 ~ 500米, 满足高层和超高层建筑灭火高度要求, 射程可以达到 800 ~ 2000米远, 实现远程灭火, 是一种革命性的原理性技术创新。 当然射程越远, 越需要好的保 护措施, 例如在投射管内设置推送座管, 或液体投射弹上设置推送底座、整流罩、 稳定翼等, 防止液体投射弹在投射管内或在投射途中爆裂。 因此, 基于所述的应 用方法, 利用本发明投射装置投送液体投射弹, 不仅可以实现高层建筑、 森林、 油田等场所的高射程或远程灭火, 还可以实现许多其他功能。 例如, 也可以用于 沙化地区的生态恢复或緩解荒山、 草场的旱情, 具体操作时, 只需要将利用投射 装置将装有水的本发明液体投射弹直接投送到荒山、草场或沙化地区即可。此外, 还可以用于防治森林或草原的病虫害, 或是用于为草木追肥等, 或卫生防疫。 根 据要实现的目的不同, 本发明液体投射弹中的功能液体还可以是混有灭火剂、 肥 料或药剂的水, 然后利用投射装置将装有功能液体的本发明液体投射弹直接投送 到目标场所即可, 水中添加上月巴料可以施月巴, 水中添加上药剂可以灭虫或防疫。 将本发明投射装置装配在船上, 还可以用于实现朴灭水上船舶、 作业平台、 岸边 设施等场所的火灾。
由于利用本发明投射装置投掷液体投射弹的距离可以达数百米乃至过千米, 而一般的水龙采用喷射原理, 其射程不过百米, 因此在一些特殊场合应用, 也可 以获得远距离的优势。其可以用于某些场合维持秩序的远距离、低强度驱离制止, 如违法示威、 哄抢、 街头打斗等,; 当然, 也可以用于驱离海盗, 或用于驱离非法 进入领海的的船只的。
此外, 另外, 除了水作为功能液体外, 本发明液体投射弹中还可以设置酒精 或燃油等其他功能液体, 以实现不同的功能。 例如, 向疫区投射装有医用酒精作 为功能液体的液体投射弹, 可以实现远距离消毒作业; 利用装有高度酒精和燃油 作为功能液体的液体投射弹, 可以安全快速地实现远距离放火垦荒作业, 都在本 发明要求的保护范围之内。
试验表明, 应用本发明投射装置, 按照本发明所述的投射方法, 可以对所述
液体投射弹实现远距离的投送。 下表给出了二组经验数据给予佐证。
综上所述, 本发明液体投射弹及其投射装置, 经济实用, 操作筒便, 本发明 利用投射装置投射液体投射弹的方法, 可靠易行, 其适于大范围普及, 市场应用 前景十分广阔。
实施例二
如图 7所示本发明液体投射弹, 与实施例一中液体投射弹的区别在于, 弹壳 1由阻燃材料的塑料膜构成, 弹壳 1前部的外表面还设置有弹壳破裂诱发装置, 所述弹壳破裂诱发装置为弹壳壳体上一体化设置的尖锐物 28, 尖锐物 28的材料 与弹壳相同, 均为 PVC材料。
本例所述本发明液体投射弹采用一端已预先封闭好的半成品弹壳, 应用实施 例一所述的投射装置进行制造和投射, 其过程基本相同, 在此不再重复。 本例所 述技术方案中, 弹壳 1壳体上设置了尖锐物 28 , 当本发明液体投射弹在投送至目 标地后,弹壳受到撞击时尖锐物 28会反向刺入弹壳内,促使弹壳壳体破裂从而将 内部的功能液体散出, 使用效果更加可靠。
当然, 基于本例所述的技术原理, 尖锐物 28也可以采用其他结构形式, 此 夕卜, 尖锐物 28的材料也可以与弹壳的材料有所不同, 如金属、 尼龙、 聚碳酸酯, 都^^于本发明技术原理的筒单变化, 都在本发明要求的保护范围之中。 另外, 基于本例所述的原理, 也可以在弹壳表面通过热合或贴附设置脆裂物, 所述脆裂 物指受撞击后可以产生带尖角的碎片的物体, 例如硬塑料片等, 与尖锐物相似, 受撞击后, 脆裂物破碎, 其碎片尖角在弹壳变形的过程中会刺破弹壳壳体, 从而 达到促使弹壳内部功能液体散出的目的, 也在本发明要求的保护范围中。
实施例三
如图 8所示本发明液体投射弹, 与实施例二的区别在于, 弹壳 1的内部设置 弹壳破裂诱发装置, 所述弹壳破裂诱发装置为弹壳壳体内部设置的、 带尖角的圓 柱形硬物 28, 硬物 28与弹壳的材料不同, 其具体由硬质工程塑料制成, 与构成 弹壳的阻燃塑料膜预先热贴合成一体。
本例所述液体投射弹也可以应用实施例一所述的投射装置进行制造和投射, 其过程基本相同, 在此不再重复。
由于弹壳内部设置了弹壳破裂诱发装置, 本发明液体投射弹在投送至目标地 后, 弹壳受到撞击时, 带尖角的圓柱形硬物 28会辅助戳穿弹壳壳体, 帮助实现弹 壳壳体破裂, 从而将内部的功能液体散出, 使用效果更加可靠。
同样, 基于本例所述的技术原理, 除圓柱形以外, 硬物 28 的也可以设置成 其他结构形式, 例如可以设置成圓锥形、 三棱锥形、 四棱锥形等结构形式, 都可 以起到很好的效果。
对于弹壳采用柔性材料制成的本发明液体投射弹, 通过在液体投射弹的弹壳 1上增设推送底座 29, 投送过程中液体投射弹的意外损坏更少, 投送效果更好, 效率更高, 实用性也更强。
实施例四
如图 9所示本发明液体投射弹, 与实施例三的区别在于, 弹壳 1由阻燃且可 以自然降解的硬塑料制成, 弹壳 1前部的外表面还设置有弹壳破裂诱发装置, 所 述弹壳破裂诱发装置为弹壳壳体上设置的多处局部薄弱区 31 , 图 9中横竖交错设 置的筋肋 30之间围成的空间部分的壳体厚度小于筋肋及弹壳下部壳体的厚度,即 为所述的局部薄弱区 31。 需要指出的是, 由于本例所述技术方案中, 弹壳采用硬 质塑料材料制成, 其承受压力的能力较柔性的塑料膜强许多, 因此本例中弹壳上 不需要再设置推送底座。
如图 10所示, 本例所述本发明投射装置与实施例一中所述投射装置的区别 在于, 本例所述投射装置中, 弹体包装装置仅由进料管 17、 计量装置、 进料开关 19、 弹壳夹持装置 23、 弹壳开启装置 20、 弹壳封闭装置构成, 其余各部分结构完 全相同。下面结合图 10具体说明本例所述投射装置中弹体包装装置制造液体投射 弹的过程: 首先, 将弹壳送至灌注工位, 弹壳开启装置 20将弹壳 1的进料通道 4 撑开, 同时弹壳夹持装置 23从外部托持着整个弹壳; 然后,储液罐 9中的水经进
料管 17 进入弹体包装装置中, 水经过计量装置的计量后, 沿撑开的进料通道 4 灌入弹壳 1中, 当通过流量控制计 18的水达到设定的流体体积时,弹壳 1中已经 灌满了水, 信号控制装置 82动作, 进料开关 19关闭, 停止向弹壳 1中灌注水; 接着, 热封合装置 22动作, 将进料通道 4封闭, 再利用切断装置 21将多余的弹 壳部分裁切掉, 制成最终的本发明液体投射弹 24。 制造好的液体投射弹装填到投 射装置中各个投射管 8的投射腔 25内并封闭投射腔, 即可用于投射, 如图 11所 示。
利用本例所述投射装置投送图 9所示液体投射弹的过程与实施例一中所描述 的过程基本相同, 在此不再重复。
本例所述液体投射弹利用在弹壳上设置局部薄弱区 31 , 在投送至目标地后, 由于弹壳壳体各部分强度不均, 弹壳受到撞击时局部薄弱区 31更容易发生破损, 从而将弹壳内部的功能液体散出, 使用效果更加可靠。 另外, 由于采用了阻燃且 可以自然降解的材料, 本例所述液体投射弹的使用后不会污染环境, 环保效果更 好。
实施例五
如图 12所示本发明液体投射弹, 与实施例三的不同之处在于, 弹壳 1 由硬 塑料制成, 为了优化发射飞行时的空中姿态, 保证投射的精确度, 弹壳 1头部一 体化设有整流罩 35。 此外, 为了提高局部强度, 防止发射过程中弹壳尾部受力发 生意外破损, 弹壳 1的尾部设置局部加强层 33。 局部加强层 33处的弹壳壳体厚 度大于其他部位弹壳壳体的厚度, 以适应投射阶段液体投射弹在惯性反力的作用 下下半段的水压更高。 因此, 整个弹壳 1的前部均相当于所述的薄弱区。 另外, 为了密封弹壳 1中的水 2, 在弹壳尾部的进料通道处设置软橡胶塞 34。
由于弹壳前端设置了整流罩 35 , 提升了弹壳 1头部的强度, 其可以减少液体 投射弹前端在飞行过程中的变形, 从而减小空气阻力, 因此有利于提高投射的精 确度。 此外, 如果采用刚度大、 脆性强的材料制成整流罩 35, 在受到撞击时, 整 流罩破碎后产生的碎片也可以起到辅助戳穿弹壳壳体, 帮助实现弹壳壳体破裂, 从而将内部的功能液体散出的作用, 此时, 整流罩也可以等同于所述的弹壳破裂 诱发装置。
如图 13所示本发明投射装置, 与实施例一中所述投射装置的不同之处在于, 将每一列的三根投射管 8作为一组, 每组投射管共用一个投射开关 7, 每个投射 开关 7都设有自动关闭机构, 相邻投射开关 7之间设有延时开启机构, 上一个投
射开关的自动关闭机构与下一个投射开关的延时开启机构联动。 投射管 8上设有 泄压装置, 泄压装置为投射管 8靠近出口端设置的扩张段 83 , 扩张段 83的管腔 直径由内端向外端逐渐增大。 瞄准系统中还包括气象感知系统和弹道计算系统, 气象感知系统包括风速计 36,风速计 36的测量结果通过数据线 45输入弹道计算 系统 37, 弹道计算系统 37 自动计算出最佳投射弹道曲线, 进而计算出投射压力 和投射管组瞄准参数。 此外, 本例中投射装置的前支脚为液压支脚 38。 使用时, 根据弹道计算系统 37的计算结果, 通过控制液压支脚 38调整投射管组的仰角来 实现液体投射弹的投送路线为沿最佳投射弹道曲线。 此外, 如图 14所示, 本例所 述投射装置中的弹体包装装置的结构更加筒单, 与图 5所示弹体包装装置相比, 其弹壳封闭装置仅为软橡胶塞 34, 当弹壳 1中灌满水后, 弹壳夹持装置 23将半 成品液体投射弹托持运送至下一工位, 在该工位设有真空吸附装置 39, 利用真空 吸附装置 39将软橡胶塞 34运送并装配在半成品液体投射弹尾部, 实现弹壳的密 封, 制成如图 12所示最终的本发明液体投射弹 24成品。 另外, 如图 15所示, 本 例所述投射装置中,构成投射管组的每根投射管 8的投射腔内 25还分别设有推送 座管 41 , 相应的投射管 8内还设有推送座管复位机构, 所述推送座管复位机构由 投射管 8内壁上设置的限位台阶 42, 以及限位台阶 42上固定设置的复位弹簧 40 及组成。 为了满足长时间工作的要求, 本发明投射装置中功能液体源包括储液罐 9和液体输送泵 51 , 其中, 液体输送泵 51与储液罐 9相连, 可以就近取水注入储 液罐 9中。
应用本发明投射装置投送图 12所示液体投射弹的过程如下: (1 )利用弹体 包装装置将水这种易取材的功能液体包装在弹壳 1内, 制成液体投射弹 24; ( 2 ) 将制备好的液体投射弹 24存放在投射装置的储弹箱 11内; (3 )确定投射目标, 根据射程将投射装置稳定安置于投射目标附近; (4 )利用风速计 36和弹道计算系 统 37确定最佳投射弹道曲线及投射参数, 并通过液压支脚 38调整投射管组的仰 角; ( 5 )瞄准投射目标后,利用送弹装置 12将储弹箱 11内的液体投射弹 24装填 到各个投射管 8的推送座管 41内并封闭投射腔 25; ( 6 )根据投射参数, 确定蓄 压调节罐内的压力满足投射压力要求, 大于设定的投射压力时, 利用压力调节装 置 6泄压,小于设定的投射压力时,通过压力调节装置 6利用压缩气源给与增压, 直至蓄压调节罐 5内的压力达到设定的投射压力; (7 )如图 13和图 15所示, 启 动一个投射开关 7使蓄压调节罐 5与一组投射管的投射腔 25连通,高压气体进入 第一组投射管的投射腔, 将各投射腔中的推送座管 41及液体投射弹 24—起推射
出去,推送座管 41撞击限位台阶 42上的复位弹簧 40后回弹, 重新复位, 液体投 射弹 24则被推射出投射管 8,在液体投射弹射出投射管的同时,投射开关 7关闭, 点修正投射管 8的水平方向、 仰角或发射压力等参数; (9 )将下一组液体投射弹 24分别装填到各投射管 8的推送座管 41中, 继续下一轮发射。
本例所述投射装置中, 投射管 8靠近出口端设置了扩张段 83 , 扩张段 83的 管腔直径由内端向外端逐渐增大, 呈喇叭口状, 因此液体投射弹在发射过程中, 经过扩张段 83时,一开始液体投射弹的弹壳随着投射管管径变化逐渐变粗, 当受 弹壳原始尺寸和张力约束不再变粗时, 液体投射弹和投射管管壁之间出现间隙, 逐渐有气体从该间隙逸出, 投射管内的气体逐渐泄压, 当液体投射弹完全脱离投 射管时, 液体投射弹的弹壳已能承受业已泄压的气压。 可以有效避免投射过程中 液体投射弹部分露出投射管时, 液体投射弹底部承受投射高压, 而前端仅承受大 气压, 压差过大容易引发弹壳爆裂的问题。 此外, 推送座管复位机构中除了利用 复位弹簧帮助推送座管 41复位外,也可以利用在投射管上设置吹气孔等方式帮助 推送座管 41复位, 也在本发明要求的保护范围内。
基于本发明技术原理, 所述瞄准系统中的气象感知系统可以包括风速计、 风 向仪、 气压计、 温度计中的至少一种。 另外, 投射管组的设置也可以根据需要进 行组合, 例如除了象本例中说的每例三根投射管为一组外, 也可以将每一排的四 根投射管设为一组, 共用一个投射开关, 或者每一排的四根投射管两两一组, 共 用一个投射开关, 都可以实现很好的效果。
本例所述本发明投射装置的结构更加筒单, 由于在投射管内设置了推送座 管, 可以有效保护液体投射弹在投射过程中免受损坏, 投送效率更高, 使用效果 更好。 特别是当液体投射弹的弹壳采用易撞击破裂的柔性材料制成时, 保护效果 更好, 用于发射图 1、 图 7或图 8所示液体投射弹时, 液体投射弹甚至可以不必 设置推送底座, 有利于筒化液体投射弹的结构, 此外, 由于不用设置推送底座, 还可以相应筒化本发明投射装置中弹体包装装置的结构。 例如, 如果不用设置推 送底座, 图 6所示弹体包装装置中可以省略真空吸附装置 32。 上述技术方案仅为 本发明图示技术方案的筒单变化, 其技术原理相似, 在此仅以文字进行说明, 也 在本发明要求的保护范围之中。
要说明的是, 图 13所示本发明投射装置如果装配在船上, 还可以用于船舶、 石油平台等设施的水上灭火, 由于此类环境下水源充足, 取水容易, 因此投射装
置中功能液体源也可以仅由液体输送泵 51构成, 利用液体输送泵 51直接为弹体 包装装置提供功能液体, 也能实现同样的功能, 这一点也适用于本发明其他实施 例, 在此一并说明, 也在本发明要求的保护范围之中。
当然, 本例中虽然仅以水做为功能液体使用,但实际应用中,根据用途不同, 也可以在水中增设添加剂或使用其他功能液体。 例如, 本例所述的液体投射弹在 用于灭火时, 可以在水中添加灭火剂; 在治理荒山荒地时, 可以在水中添加液体 化肥; 在防治森林草原病虫害或灾区疫情时可以在水中添加农药; 实现疫区远距 离免疫消毒作业时, 可以投射装有医用酒精或混有药剂的水作为功能液体的液体 投射弹; 利用装有燃油作为功能液体的液体投射弹, 可以安全快速地实现垦荒作 业等, 都在本发明要求的保护范围中, 在此一并说明, 不再——举例。
实施例六
如图 16所示本发明液体投射弹, 与实施例五的区别在于, 弹壳 1 由硬纸壳 制成,硬纸壳内表面喷有拒水材料,硬纸壳还利用阻燃液体浸泡进行过阻燃处理, 另外, 弹壳 1上还同时设有整流罩 35和稳定翼 43。 整流罩 35由脆性强的硬塑料 制成, 粘贴在弹壳 1的头部。
如图 17 所示本发明投射装置, 与实施例五中所述投射装置的区别在于, 瞄 准系统中还包括转角调节机构, 转角调节机构为一旋转底盘 46。 将投射管组设置 在旋转底盘 46上, 并在投射管组与旋转底盘 46之间设置有仰角调节机构, 仰角 调节机构具体为液压支脚 38。 另外, 压缩气源 50、 蓄压调节罐 5、 多根投射管 8 构成的投射管组、 液体输送泵 51、 储液罐 9、 弹体包装装置 10、 储弹箱 11、 送弹 装置 12及旋转底盘 46等均设置在与卡车 47一体化设置的固定底盘 58上, 构成 投射车, 投射车上还设有液压稳定支腿 52。 利用本例所述投射装置制造和投射图 16所示液体投射弹的过程与实施例五中的描述基本相同, 在此不再重复描叙。 需 要指出的是,本发明投射装置在发射前,应利用液压稳定支腿 52将投射车的其余 部分顶起, 以保证水平和稳定。 另外, 由于设置了旋转底盘 46, 在调整好液压稳 定支腿 52后, 当需要水平调整投射方向时仅转动旋转底盘 46即可以实现, 不需 要再移动投射车的位置, 十分方便。 为了防止蓄压调节罐 5意外泄压, 在蓄压调 节罐 5与压缩气源 50之间的管路上设置单向阀 59。
本例所述的本发明液体投射弹由于同时设置了整流罩 35和稳定翼 43 , 飞行 过程中更加稳定, 投射的准确性更好。 本例所述本发明投射装置, 由于配备了卡 车 47, 因此机动性更好, 使用更方便, 更适于野外作业。 需要指出的是, 基于本
例所述液体投射弹的技术原理, 弹壳上也可以仅设置稳定翼, 也可以实现很好的 效果, 另外, 本例中以均匀布置四片稳定翼为例进行说明, 在实际应用中也可以 设置三片、 五片甚至更多片稳定翼, 一般来说稳定翼都采用均匀布置的方式, 都 可以实现相同的效果。 基于本例的技术原理, 根据用途不同, 瞄准系统中也可以 仅设置转角调节机构, 而不设置仰角调节机构。 由于使用脆性强的材料制成整流 罩 35, 在受到撞击时, 整流罩破碎后产生的碎片可以帮助戳穿弹壳壳体, 从而将 弹壳内部的功能液体散出, 因此本例中, 整流罩 35同时也是弹壳破裂诱发装置。
另外要指出的是, 本例将本发明投射装置的所有功能装置全部集成在一辆卡 车上, 实际应用中也可以将部分功能装置设置在其他卡车上, 例如可以将抽水泵 及储液罐设置在其他车辆上, 下面以灭火为例说明这种应用的好处, 当火灾较大 并且火场没有大量水源时, 可以利用多辆带有抽水泵及储液罐的专用运输车就近 取水, 并运往本发明投射装置的工作现场, 这样可以解决单个储液罐容量有限, 难以实现大投送量灭火任务的缺陷;同时还可以解决单辆专用运输车上空间有限, 难以同时容纳本发明投射装置的所有功能装置的问题; 此外, 机动性也更好, 有 利于实现大投送量的工作。 基于上述原理, 也可以将蓄压调节罐设置在另外的专 用运输车上。 将本发明投射装置的功能装置分别设置在一辆、 二辆或多辆专用运 输车上的技术方案, 其工作原理相同, 都在本发明要求的保护范围内。
基于本例的技术内容, 本发明液体投射弹的弹壳除了采用硬纸壳制成外, 还 可以采用塑料或硬纸壳与塑料的复合材料制成。 此外, 出于环保的考虑, 优先采 用可自然降解的材料。 都是基于本发明技术原理的筒单应用, 都在本发明要求的 保护范围中。 另外, 为了达到阻燃的目的, 构成弹壳的硬纸壳还利用阻燃液体浸 泡进行了阻燃处理, 在实际应用中, 阻燃处理的具体方式可以多种多样, 例如, 其还可以是在弹壳表面利用粘贴、 喷涂等工艺设置阻燃材料层等, 都可以实现同 样的效果, 也在本发明要求的保护范围中, 不再另外附图给予说明。
实施例七
如图 18 所示本发明投射装置, 与实施例六中所述投射装置的区别在于, 当 仅用城区内高层建筑消防灭火时, 由于城区内消防补水较容易, 为节省空间, 储 液罐 9不再额外设置抽水泵。 此外, 对于许多城区内火场来说, 其规模有限, 但 需要精准投射, 因此本例中本发明投射装置仅设置一根投射管 8, 并且适当增长 投射管的长度。 另外, 由于城区内灭火对投射精度要求更高, 因此本例中投射装 置的瞄准系统 62中同时包括激光测距仪、光学瞄准仪、仰角测量仪、转角测量仪,
瞄准系统 62中的气象感知系统包括风速计、 风向仪、 气压计、 温度计, 此外还包 括与实施例六中相同的转角调节机构或 /和仰角调节机构。气象感知系统的测量结 果输入弹道计算系统 37, 进而计算出投射压力和投射管瞄准参数, 并相应调整仰 角、 水平转角和投射压力。 为了进一步提高投射的精确度, 瞄准系统中还包括弹 着点人工修正装置 53。
弹着点人工修正装置 53根据测得的实际弹着点与设计弹着点的偏差, 计算 出投射压力或投射管瞄准参数的调整值, 再依靠人工通过手轮调整投射管的水平 转角、 仰角或蓄压调节罐的压力。 当然, 基于上述技术原理, 也可以利用弹着点 自动修正装置替代弹着点人工修正装置 53,依靠软件系统计算出投射压力或投射 管瞄准参数的调整值, 并向转角调节机构、 仰角调节机构或压力调节装置传达信 号指令, 自动调整投射管的水平转角、 仰角或蓄压调节罐的压力, 也可以实现对 弹着点位置的精确调整, 也在本发明要求的保护范围之内。
另外, 本例所述投射装置中瞄准系统中涉及的测量工具也更多更精确, 结合 弹着点人工修正装置共同使用, 可以显着提高投射装置的投射精确度, 减少投送 过程中因误投为周边带来的意外损失, 以满足城区消防的使用要求。
实施例八
如图 19 所示本发明投射装置, 与实施例六中所述投射装置的区别在于, 投 射装置中的储液罐 9、 弹体包装装置 10及储弹箱 11设置在另一辆卡车 63上, 组 成弹体包装车 60。 投射装置的其余部分及另一个储弹箱 11仍设置在卡车 47上, 构成投射车 61。 为了保证工作时的平稳, 弹体包装车 60及投射车 61上均设有液 压稳定支腿 52。
本例中将投射装置分别设置在二辆卡车上, 组成相互配合使用的弹体包装车 60和投射车 61。 弹体包装车 60负责筹集和储存功能液体、 制造液体投射弹和储 存液体投射弹, 并且在应用时向投射车提供液体投射弹, 投射车上设置储弹箱与 弹体包装车上设置的储弹箱可以互换, 当投射车将储弹箱内的液体投射弹全部投 射完毕以后,将空的储弹箱卸下,再将装存有弹体包装车 60制备的液体投射弹的 其他储弹箱整体吊运到投射车 61上, 与送弹装置 12对接, 就可以开始新一轮的 投射, 空的储弹箱送回弹体包装车, 重新装存液体投射弹。 实现储弹箱 11的循环 使用。 由于分在两辆车上设置, 空间相对宽松, 可以大大提高本发明投射装置存 储及制造液体投射弹的能力, 为大规模投射提供有力保障。 另外, 当工作地点旁 边没有水源时,可以利用两辆弹体包装车 60轮流去附近水源处取水并生产液体投
射弹以供应投射车 61使用,可以保证大投送量时的使用需求。当然为了方便取水, 如图 19所示, 在弹体包装车 60上设置液体输送泵 51与储液罐 9配套使用。
根据不同的用途, 本发明投射装置在制造液体投射弹之前, 有时还需要在储 液罐的水中混入灭火剂、 肥料或农药等添加材料, 为了使添加材料混合均匀, 还 可以在储液罐 9上设置搅拌装置 64。 当然, 基于本发明的技术原理, 也可以额外 单独配备搅拌装置 64, 需要时, 再利用人工操作搅拌装置进行搅拌作业, 都可以 实现同样的效果, 都在本发明要求的保护范围之内。 由于用来混合液体的搅拌装 置为生产中常用设备, 在现实生产生活中十分常见, 本发明中可以应用现有各种 混合液体的搅拌装置, 在此不对搅拌装置作过多说明。
根据本实施例记录的技术原理, 投射车 61 上也可以不设置储弹箱, 改为在 投射车的送弹装置 12上设置与储弹箱 11对接的接口, 应用时, 将弹体包装车 60 上的储弹箱与投射车的送弹装置 12直接对接,利用送弹装置 12从储弹箱 11接收 液体投射弹, 并装填至投射管 8的投射腔中, 进而完成投射, 也在本发明要求的 保护范围之中。
需要说明的是, 基于本例的技术原理, 本发明投射装置也可以设置在三辆车 上, 例如将压缩气源 50设置在第三辆车上。 一般来说, 投射车应包括旋转底盘、 固定底盘和卡车, 旋转底盘可以相对于固定底盘转动, 至少送弹装置、 投射管、 蓄压调节罐放置在旋转底盘上, 固定底盘牢固设置在卡车上。 其余的结构可以设 置在弹体包装车上, 也可以设置在第三辆车上。
实施例九
如图 20所示本发明投射装置, 与实施例七中所述投射装置的区别在于, 投 射管 8的前端设置弹体出膛传感作动装置,投射开关 7设有自动关闭机构,弹体出 膛传感作动装置包括压力传感器 65, 压力传感器 65通过线路(图中未具体示出 ) 与投射开关 7中的自动关闭机构相连。 此外, 投射管 8的前端设有一个加粗的扩 张段 85 , 扩张段 85中的管腔设有锥角, 具体的管腔由内侧到出口保持直径逐渐 增大, 呈喇叭口状。
本例中, 投射管中设置的扩张段 85与实施例五中投射管中设置的扩张段 83 的功能相同, 特此说明。 另外, 投射管 8由两种不同的管材拼接固定而成, 设有 喇叭口状管腔的扩张段 85选用外径更粗、壁厚更厚的管材,这种结构的投射管无 论是选材还是加工都更加容易, 有利于降低加工成本。 本例所述结构的投射管 8 也适用于本发明其他实施例中的投射装置, 在此一并以文字说明, 不再另外附图
说明。
投射过程中, 液体投射弹从投射管 8中射出的同时, 弹体出膛传感作动装置 中的压力传感器 65感知投射管 8中的压力变化,进而向投射开关 7传送一个电子 信号, 引发自动关闭机构动作关闭投射开关, 从而为下一次发射做准备。
基于本例所述的技术原理, 弹体出膛传感作动装置也可以由光电传感器及相 关线路来实现, 利用光电传感器感知液体投射弹的射出, 进而向投射开关 7传送 一个电子信号, 引发自动关闭机构动作关闭投射开关,从而为下一次发射做准备, 也可以实现同样的效果。 此外, 基于这种控制原理, 也可以将弹体出膛传感作动 装置通过线路与送弹装置 12以及投射开关 7中的自动关闭机构分别相连, 这样, 压力传感器感知液体投射弹发射以后, 将信号依次传送至投射开关 7中的自动关 闭机构和送弹装置 12, 进而引发自动关闭机构先关闭投射开关 7, 接着开启投射 腔,送弹装置 12进行再一次填装液体投射弹。这样可以提高投射装置的自动化程 度, 有利于进一步提高投射效率。 当然, 也可以仅利用弹体出膛传感作动装置提 供控制信号来控制送弹装置 12和开启投射腔,这些都是本发明技术方案的筒单演 变, 都在本发明要求的保护范围中。 另外要说明的是, 上述技术方案同样也适用 于本例的其他技术方案, 在此一并进行说明。
由于本例所述投射装置主要应用于城区消防, 相应的消防配套较完备, 易于 获取水源, 因此本例投射装置中, 功能液体源也可以利用液体输送泵替代储液罐 9。应用时,从消防水源或饮用水源取水, 利用液体输送泵直接向弹体包装装置提 供功能液体, 也能起到很好的效果。 另外, 由于取消了储液罐 9, 本发明投射装 置结构更加筒单,占用空间更小,利用较小尺寸和排量的卡车 47就可以实现送输, 有利于进一步提高机动性和降低消防成本。
实施例十
如图 21所示本发明液体投射弹, 与图 7所示液体投射弹的区别在于, 弹壳 1 表面设置的弹壳破裂诱发装置除了包括弹壳壳体上一体化设置的尖锐物 28外,还 包括尖锐物 28顶端通过热贴合固定设置的脆裂物 80, 脆裂物 80由硬塑料制成, 同时也作为整流罩使用。
本例所述本发明液体投射弹也可以应用实施例一所述的投射装置进行制造 和投射, 其过程基本相同, 在此不再重复。 本例所述技术方案中, 弹壳 1壳体上 设置了尖锐物 28及脆裂物 80构成的弹壳破裂诱发装置, 当本发明液体投射弹在 投送至目标地后,弹壳受到撞击时脆裂物会推动尖锐物 28反向刺入弹壳内,同时,
脆裂物 80破碎后的尖角也会帮助刺破弹壳壳体,促使弹壳壳体破裂从而将内部的 功能液体散出, 使用效果更加可靠。 增设脆裂物的另一个意义在于, 可以保护尖 锐物 28, 防止其意外受力脱落, 同时也便于存贮和搬运等, 此外, 还可以作为整 流罩使用, 减少飞行阻力。
上述实施例中给出了一些本发明液体投射弹的典型结构, 为了方便制图和说 明, 弹体外壳主要采用了炮弹形状的结构。 需要说明的是, 在实际应用中, 本发 明液体投射弹的外形并不局限于炮弹形状, 根据本发明投射装置中弹体包装装置 的不同, 还可以是输液袋形或大香肠形等其他形状, 为方便进行投射, 使用时可 以在底部增设推送底座, 只要便于自动包装和利用气压投送, 都可以应用于本发 明中。 由于输液袋形或大香肠形等形状的液体包装形式在生活中非常常见, 因此 本文中仅在此以文字进行说明, 不再另外附图。 本发明投射装置中弹体包装装置 的结构也并不局限于本发明的附图所示,其也可以采用现有的液体自动灌装装置, 例如安徽正远包装科技有限公司生产的 VFS系列的制袋充填包装机,或者上海星 飞包装机械有限公司生产的液体自动包装机等, 其原理都可以适用于本发明投射 装置中。 当然, 对于已成形的弹壳, 也可以仅利用液体自动灌注设备。 利用上述 液体自动灌注设备或包装设备作为弹体包装装置, 可以自动完成本发明液体投射 弹的全套加工工序, 快速地批量生产本发明液体投射弹。 以上说明适用于本发明 所有的实施例, 也在本发明要求的保护范围之中。
实施例十一
如图 22、 图 23和图 24所示本发明液体投射弹, 与图 16所示液体投射弹的 区别在于, 稳定翼 43—直延伸至弹壳 1的中部。 此外, 稳定翼 43沿弹壳 1外表 面呈螺旋状布置。弹壳内利用与弹壳 1设置成一体的隔板 89将弹壳内的空间分隔 成四个腔室, 隔板 89的中下部设置有若干个小孔 90将四个腔室连通。
要说明的是, 图 22、 图 23和图 24中为了表示清楚本发明液体投射弹的各部 分结构, 稳定翼 43呈打开状态, 在实际应用时, 纸板制成的稳定翼 43贴附弹壳 1 外表面设置, 仅在处于转动飞行状态时, 稳定翼才会张开, 如图示状。 此外, 设置隔板 89的目的在于,避免弹壳内的液体由于惯性作用,在液体投射弹在投射 后的旋转飞行中无法随着弹壳一起转动。 由于隔板 89的存在,可以在液体投射弹 旋转飞行过程中推动功能液体与弹壳一起转动, 因此飞行更加稳定。 另外, 由于 隔板 89将弹壳内分隔成四个腔室, 为了防止在向弹壳内灌注功能液体的过程中, 出现每个腔室中灌入的功能液体总量不同的情况,在隔板 89的中下部设置有若干
个小孔 90将四个腔室连通,从而保证四个腔室中的功能液体分配均匀。 当然, 本 例以隔板将弹壳内的空间分隔成四个腔室为例进行说明, 在实际应用中, 也可以 分成二个腔室、 三个腔室或四个以上的腔室, 都能实现同样的功能, 但为了方便 灌注功能液体, 腔室不宜过多。 基于上述技术原理, 当分隔出的腔室较少时, 例 如二个腔室, 为了加快灌注速度, 也可以使用两个管路分别对两个腔室灌注功能 液体, 因此也可以不在隔板上设置小孔将腔室彼此连通, 二个腔室保持彼此独立 即可。 上述技术都是基于本例所述技术原理的筒单变化, 都在本发明要求的保护 范围之中。
为了方便应用图 22、 图 23和图 24所示液体投射弹, 由图 25所示本发明投 射装置,与图 17所示投射装置的区别在于,投射管 8的管腔内表面设置旋转的滑 膛槽 86。 为了防止在投射液体投射弹的过程中划伤弹壳, 滑膛槽 86的所有凹凸 表面均为圓滑表面。 这样, 液体投射弹出膛时, 具有旋转动能, 飞行姿态更加稳 定。 另外, 投射管 8上设置了泄压阀 87, 以替代图 17所示投射装置中投射管前 端设置的扩张段带有锥角的结构。 其技术原理是, 当液体投射弹即将射出投射管 时, 泄压阀 87动作, 将液体投射弹尾端的投射压力释放, 液体投射弹依靠惯性射 出, 在离开投射管时, 液体投射弹的弹壳已能够承受前后两端的压力差。 这样, 就可以有效避免投射过程中液体投射弹部分露出投射管时, 液体投射弹底部承受 投射高压, 而前端仅承受大气压, 压差过大容易引发弹壳爆裂的问题。
应用本例所述投射装置制造和投射图 22、图 23和图 24所示液体投射弹的过 程与利用图 17所述投射装置制造和投射图 16所示液体投射弹的过程基本相同, 在此不再重复描叙。
实施例十二
如图 26和图 27所示本发明投射装置, 与图 3所示投射装置的区别在于, 投 射管 8的管腔内设置低摩擦阻力材料构成的村套 88,所述低摩擦阻力材料为 PTFE 材料。
本例所述本发明投射装置的应用方法与实施例一中对图 3所示投射装置的描 述完全相同, 在此不再重复。 由于在投射管的管腔内设置了村套 88, 可以有效防 止在投射过程中, 因投射管管腔侧壁不光滑而滑伤弹壳。
根据本例所述的技术原理, 除了在投射管管腔内设置低摩擦阻力材料构成的 村套外, 也可以在投射管的管腔内设置低摩擦阻力材料构成的镀膜, 所述低摩擦 阻力材料包括尼龙材料、 PVC材料、 氟化石墨烯材料、 特氟龙材料或可用于电镀
的金属材料等, 所述可用于电镀的金属材料包括辞、 镍、 铬等, 都能实现同样的 效果, 在此, 仅以文字的形式进行描述, 不再——附图进行说明, 也在本发明要 求的保护范围之内。
实施例十三
如图 28所示本发明投射装置, 与实施例八的区别在于, 在弹体包装车 60中, 弹体包装装置 10与储弹箱 11之间增设中间搬运工位 54。
应用时, 与实施例八的区别在于, 当弹体包装车 60制造液体投射弹时, 通过 弹体包装装置 10制成的液体投射弹首先被送至中间搬运工位 54, 在中间搬运工 位 54利用人工或者是码 4^几器人(图中未具体示出 )再将液体投射弹摆放在储弹 箱 11中。
实施例十四
如图 29所示本发明液体投射弹, 与图 1所示液体投射弹的区别在于, 弹壳 1 两端均用金属卡 81扎紧封闭。 此外, 弹壳 1的外表面还设有减阻耐磨层 160, 所 述减阻耐磨层 160由低摩擦系数材料构成,在此具体由特富龙材料构成。
由于在弹壳 1外部设置了特富龙材料构成的减阻耐磨层 160,在发射过程中可 以有效防止液体投射弹与投射管管壁磨擦造成的弹壳意外破损, 提高投送的可靠 性和投送的效率。 此外, 由于减阻耐磨层 160可以起到与实施例一中的推送底座 同样的作用, 因此本例中液体投射弹中不再设置推送底座, 实际应用中, 可以预 先在构成弹壳 1的塑料膜表面一体化设置特富龙材料构成的减阻耐磨层, 有利于 减化产品结构, 减少液体投射弹产品的制造工序, 降低制造和运输难度, 提高产 品的实用性。
实施例十五
如图 30和图 31所示本发明液体投射弹,与图 12所示液体投射弹的区别在于, 弹壳 1的外表面上还设有压力平衡槽 162, 所述压力平衡槽 162由弹壳 1表面一 体化设置的凸起 161围成, 压力平衡槽 162设有向弹壳 1尾部开放的豁口。
由于弹壳 1 的外表面增设了压力平衡槽 162, 当本发明液体投射弹装入投射 管, 凸起 161与投射管管壁接触后, 压力平衡槽与投射管管壁一起构成气室, 气 室与投射腔连通, 当液体投射弹在气体压力推动下沿投射腔移动过程中, 气室减 小了液体投射弹与投射管管壁的接触面积, 气室中的空气还可以起到润滑作用, 能够有效避免液体投射弹在发射过程中意外破损导致的弹壳中存储的功能液体提 前散出, 从而提高投送的可靠性和投送的效率。
实施例十六
如图 32所示本发明液体投射弹, 与图 1所示液体投射弹的区别在于, 弹壳 1 外表面设置推送外壳 163,推送外壳 163表面还设有减阻耐磨层 164,所述减阻耐 磨层 164由低摩擦系数材料构成,在此具体由尼龙材料构成。
由于在弹壳 1外部设置了尼龙材料构成的减阻耐磨层 164,在发射过程中可以 有效防止液体投射弹与投射管管壁磨擦造成的弹壳意外破损, 从而提高投送的可 靠性和投送的效率。
实施例十七
如图 33和图 34所示本发明液体投射弹, 仍采用水 2作为功能液体, 与图 1 所示液体投射弹的区别在于, 塑料膜制成的弹壳 1二端全部采用热贴合工艺进行 封闭。 此外, 在弹壳 1外表面局部套设推送外壳, 所述推送外壳包括摩擦保护壳 150和润滑保护壳 151 ,其中,润滑保护壳 151固定设置在摩擦保护壳 150的外侧 表面,润滑保护壳 151上设有多个压力平衡槽 152,压力平衡槽 152设有向弹壳 1 尾部开放的豁口。 摩擦保护壳 150和润滑保护壳 151均由硬纸壳制成, 并且润滑 保护壳 151与摩擦保护壳 150粘贴固定成一体。
与实施例一相比, 本例所述本发明液体投射弹在制造过程中弹壳 1二端全部 采用热贴合工艺进行封闭, 其投射过程与实施例一基本相同, 在此不再重复。 此 夕卜, 与实施例十五中描述的原理相似, 由于在弹壳 1外部套设了摩擦保护壳 150 和润滑保护壳 151构成的推送外壳, 并且润滑保护壳 151的外表面增设了压力平 衡槽 152, 当本发明液体投射弹装入投射管, 压力平衡槽 152周边的凸起部分与 投射管管壁接触后,压力平衡槽与投射管管壁一起构成气室,气室与投射腔连通, 而且发射过程中, 弹壳 1与投射管内壁无直接接触, 当液体投射弹在气体压力推 动下沿投射腔移动过程中, 气室减小了液体投射弹与投射管管壁的接触面积, 气 室中的空气还可以起到润滑作用, 能够有效避免液体投射弹在发射过程中意外破 损导致的弹壳中存储的功能液体提前散出,从而提高投送的可靠性和投送的效率。
综上所述, 本例所述液体投射弹的投送损失率更低, 投送效果更好, 使用效 果更加可靠, 效率更高, 实用性也更强。 根据实施例十六和实施例十七所述的技 术原理, 本发明液体投射弹中, 所述推送外壳的结构多种多样, 其设置方式也多 种多样, 例如, 其可以设置在弹壳的底部及部分侧面上, 也可以设置在弹壳的底 部及全部侧面上, 在应用时, 可以根据实际需要进行选择。
本发明液体投射弹中, 主要利用了水这种易取材的功能液体, 取材方便。 其
弹壳取材多样, 其可以由易撞击破裂的柔性或硬质材料制成, 所述易撞击破裂的 柔性材料包括塑料膜、 金属箔、 纸或上述材料中至秒二种的复合材料, 易撞击破 裂的硬质材料包括硬纸壳、 塑料或二者的复合材料。 本发明的实施例中所述的液 体投射弹的弹壳均可以根据使用要求选择上述二类材料制成, 其取材便利, 有利 于降低成本。 由于本发明投射装置可以实现加工和投送液体投射弹的全流程, 可 以避免传统灭火弹需要提前加工储存, 占用场地较大, 长期保存又容易出现过期 失效等问题,同时还可以有效解决野外作业大批量投射时投射弹的运输供应问题, 具有安全、 高效、 环保、 大投射量等优点, 其经济性、 适用性和实用性都显着提 高。 需要说明的是, 基于本发明中记录的投送原理, 本发明投射装置还可以用于 向交通受阻的受灾区投送生活用品或防护用品等, 以提高当地的救助能力, 保障 人们的生命财产安全, 也在本发明要求的保护范围中。 另外, 本发明并不局限于 上述实施例应用, 基于本文中记叙的技术原理, 相关技术方案也可以交叉使用, 都在本发明要求的保护范围中。
