Description

一种落水用安全自救包 技术领域
本发明涉及安全防护装置的技术领域，尤其是涉及一种落水用安全自救包。
背景技术
在交通出行过程中经常碰到突发状况，每年都会有交通工具落水、水浸事故的发生，造成车内人员死亡的悲剧，严重威胁了人民群众的生命安全。
当交通工具落水后，由于水造成的内外压强差导致门无法打开，这时也不能直接用破窗器击碎玻璃，因为外面的水会涌进来，人也无法游出去。这时应该等待车内外水压基本无差再用破窗器击碎玻璃进行逃生。
经调研发现，普通人在水下那么危险的情况下，闭气时间通常为30秒左右，而从找到破窗器，并用它击碎玻璃，再游上岸一路顺利的情况下所用的时间最少也是45秒左右，而现有的交通工具落水后的自救防护装置(如破窗器)不能在水下给落水者逃生提供充分的自救时间，因此有待进一步改进。
发明内容
本发明的目的是提供一种落水用安全自救包，其具有给落水人员提供应急呼吸、延长自救时间的效果。
本发明的上述技术目的是通过以下技术方案得以实现的：
一种落水用安全自救包，包括设置于交通工具外的包体、设置于包体内的纺锤形的防水气囊以及控制包体自动打开的水控组件，所述防水气囊的底端连接有出气管，所述出气管的末端连接有位于车内的呼吸面罩；所述防水气囊的侧面颈口处开设有供空气进入的进气孔一，所述进气孔一处转动连接有用于覆盖进气孔一的盖板，所述盖板上设置有启闭组件，启闭组件可以控制盖板启。
本发明进一步设置为：所述启闭组件包括连接在盖板外壁上的连接杆以及连接在连接杆末端的浮体，所述浮体内设置有钢珠，所述防水气囊的颈口外壁 上连接有扭簧，所述扭簧的一端抵接于防水气囊外壁；所述钢珠、浮体、连接杆的重力之和大于扭簧最大形变量的弹力，所述防水气囊的侧面上开设有用于容纳浮体的让位槽，所述让位槽处覆盖有滤网一。
本发明进一步设置为：所述防水气囊的颈口处环绕设置有滤网二。
本发明进一步设置为：所述进气孔一与出气管之间连通有管道一，所述防水气囊的侧面颈口处开设有供空气进入的进气孔二，所述进气孔二与让位槽分别位于防水气囊相对的侧面上，所述进气孔二与出气管之间连通有管道二，所述管道二上连接有氧气机。
本发明进一步设置为：所述启闭组件电连接有用于控制进气孔二与氧气机的开关。
本发明进一步设置为：所述出气管的末端分别连接有储气袋一与储气袋二，所述出气管与储气袋一之间连接有转接管一，所述出气管与储气袋二之间连接有转接管二，所述转接管一与转接管二的末端同连通于供气管，所述供气管的末端连接于呼吸面罩。
本发明进一步设置为：所述出气管的末端设置有多功能转接阀门，所述防水气囊的底面上设置有与出气管相通的连接口，所述连接口处连接有辅助氧气机，所述辅助氧气机上连接有支管，所述支管连接于连接口或多功能转接阀门。多功能转接阀门可以接快速充气组件，比如主动打开压缩气瓶等。

本发明进一步设置为：所述防水气囊的顶面上设置有报警器以及与报警器电连接的锂电池。
综上所述，本发明的有益技术效果为：
1、通过水控组件与防水气囊的设置，交通工具落水后，水浸传感器将检测 到的信号传到控制器，在控制器的作用下开启包体，使得防水气囊从包体中逸出，防水气囊上浮到水面后，外界空气从进气孔一经过出气管到达呼吸面罩，给落水者继续提供应急呼吸，延长自救时间；
2、通过储气袋一与储气袋二的设置，交通工具落水后，水浸传感器将检测到的信号传到控制器，在控制器的作用下开启包体，使得防水气囊从包体中逸出；防水气囊从水下上浮到水面的过程中，落水者戴上呼吸面罩，可先从储气袋一与储气袋二中获取需要的氧气；
3、通过启闭组件的设置，防水气囊上浮到水面后，让位槽中水透过滤网一散去，浮体失去浮力的支撑，在钢珠的重力作用下，向下拉动连接杆，连接杆拉动盖板打开，扭簧被压缩，此时，外界空气从管道一进入，给落水者继续提供应急呼吸，连接杆拉动盖板打开的同时，进气孔二与氧气机也打开，空气从管道二进入，给落水者继续提供应急呼吸，延长自救时间。

具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和 特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
参照图1与图2，为本发明公开的一种落水用安全自救包，包括设置于交通工具外的包体、设置于包体内的纺锤形的防水气囊1以及控制包体自动打开的水控组件，防水气囊1的颈口处较中部窄。防水气囊的形状也可以根据实际需求改变。当然，防水气囊也可以用浮体结构代替。水控组件包括设置于交通工具驾驶室前引擎盖下的水浸传感器、与水浸传感器电连接的控制器，控制器密封连接有蓄电池应急电源。防水气囊1的底端连接有出气管2，出气管2的末端连接有位于车内的呼吸面罩3。防水气囊1的侧面颈口处开设有供空气进入的进气孔一11，进气孔一11处转动连接有用于覆盖进气孔一11的盖板4，盖板4上设置有用于控制盖板4启闭的启闭组件。启闭组件电连接有用于控制进气孔二12与氧气机7的开关。交通工具落水后，水浸传感器将检测到的信号传到控制器，在控制器的作用下开启包体，使得防水气囊1从包体中逸出。
参照图1与图2，启闭组件包括连接在盖板4外壁上的连接杆41以及连接在连接杆41末端的浮体5，浮体5内设置有钢珠51，防水气囊1的颈口外壁上连接有扭簧13，扭簧13中部固定在颈口外壁上，扭簧13的一端固定于盖板4，另一端抵接于防水气囊1外壁；钢珠51、浮体5、连接杆41的重力之和大于扭簧13最大形变量的弹力，防水气囊1的侧面上开设有用于容纳浮体5的让位槽6。扭簧13未受力时，盖板4处于闭合状态。进气孔一11与出气管2之间连通有管道一21，管道一21的末端设置有单向进气阀，防水气囊1的侧面颈口处开设有供空气进入的进气孔二12，进气孔二12与让位槽6分别位于防水气囊1相对的侧面上。在水下时，水充盈在让位槽6中，浮体5受到向上的浮力，盖板4未受到连接杆41向下的拉力，因此盖板4始终盖合在进气孔一11上，同时，进气孔二12与氧气机7均处于关闭 状态。为了防止在水下时，水下漂浮的杂物进入让位槽6中，让位槽6处覆盖有滤网一61。
参照图1与图2，出气管2的末端分别连接有储气袋一8与储气袋二9，出气管2与储气袋一8之间连接有转接管一81，出气管2与转接管一81之间设置有单向进气阀，出气管2与储气袋二9之间连接有转接管二91，转接管一81与转接管二91的末端同连通于供气管31，供气管31上设置有医用调节开关，供气管31的末端连接于呼吸面罩3。防水气囊1从水下上浮到水面的过程中，落水者戴上呼吸面罩3，可先从储气袋一8与储气袋二9中获取需要的氧气，同时落水者呼出的气体也能返回至储气袋一8中，增加其浮力使其上浮。
参照图1与图2，防水气囊1上浮到水面后，由于防水气囊1呈纺锤形，防水气囊1倾斜漂浮在水面上时，进气孔二12处于背离水面的一侧。进气孔二12与出气管2之间连通有管道二22，管道二22上连接有氧气机7。防水气囊1上浮到水面后，让位槽6中水透过滤网一61散去，浮体5失去浮力的支撑，在钢珠51的作用下，向下拉动连接杆41，连接杆41拉动盖板4打开，扭簧13被压缩，此时，外界空气从管道一21进入，给落水者继续提供应急呼吸。连接杆41拉动盖板4打开的同时，进气孔二12与氧气机7也打开，空气从管道二22进入，给落水者继续提供应急呼吸。为了防止水草等杂物堵塞进气孔二12，防水气囊1的颈口处环绕设置有滤网二14。
参照图1与图2，防水气囊1的底面上设置有与出气管2相通的连接口15，连接口15处连接有辅助氧气机16，辅助氧气机16上连接有与连接口15相通的支管23，连接口15处设置有C式自锁快速接头。授权公告号为CN207921557U的中国专利已相应公开了C式自锁快速接头的具体结构，在此不做赘述。支管23可以连接连接口15，也可以连接2下方的多功能转接阀门24，当支管23与连接口15或者多 功能转接阀门24接通后，启动辅助氧气机16，实现储气袋一8与储气袋二9的快速充气。无需使用辅助氧气机16时，支管23无需接入连接口15。当出气管2的长度较长时，支管23连接多功能转接阀门24，可以使得辅助氧气机16与氧气机7同时开机，增大吸力，可以快速给储气袋一8与储气袋二9充气。一种使用中，连接口15用于连接充气气囊，用于辅助防水气囊稳定平衡。
参照图1与图2，防水气囊1的顶面上设置有报警器17以及与报警器17电连接的锂电池18，防水气囊1上浮到水面后，报警器17闪烁，给搜救人员提供搜救信号，进一步提高落水者生还的可能性。
本实施例的实施原理为：交通工具落水后，水浸传感器将检测到的信号传到控制器，在控制器的作用下开启包体，使得防水气囊1从包体中逸出；防水气囊1从水下上浮到水面的过程中，落水者戴上呼吸面罩3，可先从储气袋一8与储气袋二9中获取需要的氧气；
在水下时，水充盈在让位槽6中，浮体5受到向上的浮力，盖板4未受到连接杆41向下的拉力，因此盖板4始终盖合在进气孔一11上，同时，进气孔二12与氧气机7均处于关闭状态；
防水气囊1上浮到水面后，让位槽6中水透过滤网一61散去，浮体5失去浮力的支撑，在钢珠51的重力作用下，向下拉动连接杆41，连接杆41拉动盖板4打开，扭簧13被压缩，此时，外界空气从管道一21进入，给落水者继续提供应急呼吸，连接杆41拉动盖板4打开的同时，进气孔二12与氧气机7也打开，空气从管道二22进入，给落水者继续提供应急呼吸，延长自救时间。本申请中的扭簧13也可以用也为感应开关替代。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
