Description

绳控水上救生装置
技术领域
本发明涉及一种救生装置,尤其涉及一种绳控水上救生装置,其可以把救生浮体(如救生圈)准确投放到远超过直接抛投的距离。
背景技术
目前,水上救生主要依靠船及救生圈来实施救生的工作。标准的2.5公斤重通用成人救生圈在抛投时一般只能达到几米至十几米,因此只能救援很近的距离。当遇到洪水等水流流速较大时要实现准确抛投更加困难,有时还会发生即使抛投位置到位而被救者未能及时抓住救生圈,使得救生圈被水冲走从而造成救援失败。
远距离准确投放救生圈和在湍急水流中救援问题一直没有简便有效的解决方法。目前关于远距离投放救生圈的专利主要有两类,一类是以压缩气体、火药或者机械弹簧抛投未充气的救生圈,救生圈被抛投入水后自动充气,如中国专利CN101982371A、CN201842236U和CN202609055U等公开的都是此类产品。这些产品都不适用于湍急的水流中救生,且其结构复杂,很难操作,只有一次抛投机会,如果一次抛投失败需要花较长时间收回已抛出的救生圈并装填压缩气体、火药或者设置机械弹簧才能进行再次抛投。另一类是以电动遥控自航救生圈的方式,如CN202609055U和CN202439834U等专利中所公开的,这种产品同样不适用于湍急水流,其控制困难,维护成本很大,可靠性低。
另外,中国专利CN202368768U (急流救援系统)公开了以组合杆一端固定河岸基座一端连接充气船,利用洪水冲击力使组合杆绕基座转动,以尼龙绳、滑轮和绞盘控制组合杆转速实施救援。但是,该实用新型结构复杂,体积重量大,运输困难,装配耗时,需要一组人员协同操作。
因此,本领域的技术人员致力于开发一种绳控水上救生装置,利用救援绳、安全钩、定位环及导向舵板实现简单方便地精确控制救生圈位置。

进一步地,本发明还提供了一种导向舵板,其特征在于,包括受力迎水面;所述导向舵板上连接有绑带、绳索和/或夹具,所述绑带、绳索和夹具用于将所述导向舵板固定在救生浮体本体上;当所述救生浮体本体漂浮在水面上时,所述导向舵板至少部分地浸没于水中,所述受力迎水面和所述水面的夹角在30°到150°之间。
进一步地,所述导向舵板的一端具有突起部,所述突起部用于与所述救生浮体本体上的开孔配合。
在第一个实施例中,本发明绳控水上救生装置通过在救生浮体本体(救生浮体本体优选地为通用标准救生圈,参见标准:GB4302-2008)上以固定的、或可折叠的、或可拆卸的方式安装导向舵板,导向舵板具有为矩形平面或等效为等效矩形平面的受力迎水面(此处的等效是指两者的受力和力矩相同);在救生浮体本体的侧部上设置两个定位环,两个定位环(第一定位环和第二定位环)在相对于导向舵板的受力迎水面的矩形平面的中心处的法线呈一定角度的二对称位置处固定设置,在替代的实施例中,定位环的位置可调节;定位环到导向舵板的受力迎水面的矩形平面的两个侧边(第一侧边和第二侧边)的距离不相等,或者,定位环到导向舵板的受力迎水面的等效矩形平面的两个侧边(第一等效侧边和第二等效侧边)的距离不相等;救援绳的一端设置有安全钩,另一端用于供救援者握持;救援绳通过安全钩与定位环的配合连接到救生浮体本体上,在替代的实施例中,救援绳可以直接捆绑在定位环上或救生装置浮体本体上。绳控水上救生装置在水上使用时,救生浮体本体漂浮在水面上,导向舵板浸没于水中且其受力迎水面在30°到150°之间,较佳地,该受力迎水面垂直于水面或大致垂直于水面。
由于定位环和导向舵板的受力迎水面的矩形平面(或等效矩形平面)的两个侧边(或等效侧边)的距离不相等,在水流的冲击作用下,救生浮体本体受到水流对导向舵板的作用力及水流对救生浮体的作用力的合力是偏离河岸的,由此救援者在岸边以一定速度释放救援绳可使救生浮体本体漂离岸边,向水中的被救援者漂去;并且只要救援绳长度足够,救援者通过控制救援绳的长度和调整在岸边的位置,可以把本发明的绳控水上救生装置以类似放风筝的方式准确投放到远超过直接抛投救生浮体本体的距离,并可以按需要微调其位置,从而使救生浮体本体准确地到达被救援者处。
导向舵板的受力迎水面可以为平面也可以为曲面,可以为矩形、圆角矩形、梯形、三角形、半圆形、椭圆形、半椭圆形,多边形或不规则形,优选地,受力迎水面为矩形平面,从实用和安全的考虑导向舵板优选地为圆角矩形平板或者同救生圈部分形状重合的扇环形平板。
救援绳可使用各种柔性绳状材料,优选地采用可漂浮的4毫米至8毫米丙纶高强度专用水上救援绳(参见规范:DB37/T 1989-2011)。
救生浮体本体可以是一切可提供浮力的物体,如各种形状的泡沫塑料、木制品、轮胎及空心物体等。为利用现有器材和技术减少成本以及实现安全的救援,优选地,救生浮体本体使用通用标准救生圈(参见标准:GB4302-2008),本文以下描述及附图将以救生圈为作为救生浮体本体的实例,阐述本发明的结构和使用方法。使用救生圈以外的其他物体作为救生浮体本体时如果使用与本发明同样的原理,即救生浮体本体提供浮力,导向舵板提供横向推力(水流对导向舵板的作用力的一个分力的方向垂直于水流方向),救援绳提供对救生浮体本体的拉力,则这类应用也被包括在本发明保护范围内。
定位环是被救援绳直接绑缚或通过诸如安全钩的连接部件连接的受力点,可以为刚性环状体,如金属圈,也可为柔性环状体,如高强度尼龙绳圈,另外,救生浮体本体上的开孔也是定位环替代形式。
虽然救援绳可以直接绑缚在定位环或救生浮体本体上,为了减少救援时间,优选地,救援绳的一端安装安全钩,例如卡扣式安全钩,安全钩可以快速地与定位环配合从而将救援绳连接到救生浮体本体上。在替代的实施例中,救生浮体本体的侧部可以设置多于两个的定位环,以将救援绳连接到救生浮体本体上的不同位置处。
上述绳控水上救生装置的使用方法如下:
步骤一、救援者根据被救援者相对于自己的位置和水流的方向,将安全钩与第一定位环或第二定位环配合。救援者判断选择合适位置的定位环以与救援绳上的安全钩配合的方法可以有多种,例如通过受力分析,一种较简单的判断方法是:救援者面向被救援者站立在岸边,平持救生浮体本体并保证其上的导向舵板在救生浮体本体的下方且导向舵板的受力迎水面的矩形平面(或其等效矩形平面)平行于水流方向,将该矩形平面(或等效矩形平面)的两条侧边(或等效侧边)定义为上游边和下游边,则从上游边到下游边的方向为水流方向,选择到上游边的距离小于到下游边的距离的定位环作为与救援绳上的安全钩配合的定位环,如果符合要求的定位环有多个,则可以根据水流速度再作选择,例如在水流较快的水中救援可以选择距离上游边较近的定位环,而在水流较慢的水中救援则可以选择距离上游边较远的定位环。
步骤二、确定导向舵板相对于救生浮体本体的位置为绳控水上救生装置在水上使用时导向舵板相对于救生浮体本体的位置,即确定以可折叠的方式安装的导向舵板被打开并固定到位,以可拆卸的方式安装的导向舵板被安装到位。
步骤三、抛投绳控水上救生装置,使救生浮体本体浮于水面且导向舵板浸没于水中。
步骤四、救援者释放救援绳,使绳控水上救生装置在水流的推动下向被救援者漂去。其中,当水流速越大,救生浮体本体漂航到位的时间越短,救援使用效果越好。在急流水域,救援者只要站在上游适当距离(相对于被救援者),通过以小于水流的速度释放救援绳,就可以快速投放救生浮体本体到指定位置(被救援者处)。在水流速度较慢或者静水水域救援仍然可以使用,具体为:在被救援者的下游稍远的地方投放救生浮体本体入水,救援者向上游奔跑,边奔跑边释放救援绳,释绳速度小于奔跑速度,通过控制释绳长度和奔跑速度可以控制救生浮体本体离岸的距离。在完全静止水域不容易微调救生浮体本体的位置,可以适度增加释绳长度,让连接救生浮体本体和救援者的救援绳扫过被救援者,被救援者抓住救援绳可顺绳抓到救生浮体本体。
本发明的绳控水上救生装置的最远救援距离同救援绳的长度、导向舵板的受力迎水面的面积、与救援绳相连的定位环的位置、水流的速度、救援绳的吸水性、救援绳的单位长度重量、岸的高度及救援技巧等因素相关。例如,救援绳吸水性越大,救援绳沾水后重量越大,其下垂量也越大,当救援绳浸没于水中时,水的阻力会改变救援绳的准直度,使其向下游方向偏移呈摆线形状,由此严重影响救援绳的拉力角度。再例如,导向舵板的受力迎水面的面积和水流对导向舵板的受力迎水面的冲击力成正比,面积太小则救援绳的张力不够,使救援绳不易绷直,垂入水中影响拉力方向,面积太大则救援绳的拉力过大,增加救援人员控制难度。在救援绳为绷紧的情况下,优选的定位环的位置为其与导向舵板的质心的连线和该质心处的受力迎水面的法线方向的夹角(第一夹角)在约10°至60°之间,各个位置适用不同的水流速度,可以按需要选取。在流速较大水域如洪水中,水流对导向舵板的受力迎水面的冲击力相当大,选择第一夹角较大的定位环效果较好,例如,流速约2米/秒时优选的定位环的第一夹角约为45°,流速约1米/秒时优选的定位环的第一夹角约30°,选择合适的定位环与救援绳连接可以减小救援绳的拉力并能快速漂放救生浮体本体到位。在静水水域或流速较小水域,选择第一角度为10~20°的定位环获得的救援效果较好,这可以减少救援者的奔跑距离。一般地,在救生浮体本体的侧部设置两个第一夹角为30°的定位环,这可以适用于大多数河流流速的快速救援,另外,可以再设置一个或多个可调节位置的定位环来用于特殊情形(例如静水救援、水流速度非常低的水域中的救援或者水流速度非常大的水域中的救援)。在救生浮体本体上设置可调节位置的定位环有多种方法,例如,根据需要使用背对背魔术贴绑扣将定位环绑在救生浮体本体的合适位置上。
实验表明,在1 米/秒左右流速的状态下且河岸高7米,导向舵板的受力迎水面的面积约1000平方厘米,选择第一角度为30°的定位环连接救援绳,使用100米长的4mm高强度丙纶专用水上救援绳足以把一个通用标准救生圈漂放到离岸约60米远的地方。
在第二个实施例中,本发明的绳控水上救生装置的导向舵板是可折叠的,并且为了便于安放、携带和保存,并可作为无漂航功能的救生浮体本体使用,在救生浮体本体上设置有凹槽,供处于不使用状态的绳控水上救生装置的导向舵板嵌入其中,由此导向舵板贴合于救生浮体本体。导向舵板的一端通过铰链连接到救生浮体本体,导向舵板可绕铰链相对于救生浮体本体转动,救生浮体本体上还设置有卡口,导向舵板上具有突出部分。绳控水上救生装置在水上使用时,通过卡口咬合导向舵板的突出部分来使导向舵板相对于救生浮体本体的位置不变化,即相对于救生浮体本体固定。该突出部分和导向舵板相连的位置处设置有加强筋,以改善导向舵板受力时的强度和刚度。救生浮体本体上可以设置多个如上所述的可折叠的导向舵板,这在本发明的第六个实施例中有描述,其每个导向舵板都由铰链连接到救生浮体本体,相应地救生浮体本体上设有多个卡口,分别用于咬合各个导向以使其相对于救生浮体固定。使用时可按照水流速度决定使用导向舵板的个数,进而改变导向舵板的受力迎水面的总有效面积。导向舵板的受力迎水面的总有效面积为处于打开状态的导向舵板的受力迎水面的矩形平面(或等效矩形平面)之和。
在第三个实施例中,本发明的绳控水上救生装置的导向舵板是可拆卸的,其中的导向舵板以绑缚或者绑扣方式固定在救生浮体本体上,导向舵板具有一个或多个契合于救生浮体本体(本实施例中为标准救生圈)的底座,底座上连接有一个或多个柔性或刚性的绑缚绑扣结构,例如绑带或绳索,可以将导向舵板牢固地绑定在救生浮体本体上并使导向舵板相对于救生浮体本体固定。优选地,底座或者绑缚绑扣结构上有突起部,例如定位钉或定位销,其可以嵌入在救生浮体本体上的开孔,这可以避免导向舵板和绑缚装置发生相对于救生浮体本体的移动,例如发生沿救生圈圈体截面的周向和轴向滑动。
在第四个实施例中,本发明的绳控水上救生装置的导向舵板是可拆卸的,其中的导向舵板具有一个或多个突出部,例如定位杆或定位榫,在救生浮体本体上相应地具有一个或多个开孔,较佳地开孔为通孔。通过将导向舵板的定位杆或定位榫插入救生浮体本体上的开孔中并贯穿救生浮体本体,并通过在导向舵板的定位杆或定位榫的顶端露出救生浮体本体的开孔的部位横向地插入定位销,使导向舵板的定位杆或定位榫相对于救生浮体本体固定,并由此使导向舵板相对于救生浮体本体固定。当仅使用一个定位杆或定位榫时,其杆头或榫头的长度、厚度和高度应足够大以保证导向舵板相对于救生浮体本体的定位牢固且不会偏转。优选地,采用两个定位杆或定位榫。
在第五个实施例中,本发明的绳控水上救生装置的导向舵板是可拆卸的,其中的导向舵板具有一个或多个契合于救生浮体本体(本实施例中为标准救生圈)的底座,和一个或多个契合于救生浮体本体(本实施例中为标准救生圈)的夹持座,通过螺杆和夹紧螺母把底座和夹持座牢固夹持于救生浮体本体上,本实施例中夹持在救生圈的圈体上,可以使导向舵板相对于救生浮体本体固定。
导向舵板的受力迎水面可以是平面,也可以是曲面。第七个实施例中给出了受力迎水面为曲面的情况,此时可以把该曲面的受力迎水面分割成很多个小的平面,用微积分方程或有限元法求出与其等效的平面的受力迎水面。算法很复杂,可以以经验公式代替,例如认为曲面的受力迎水面的最大投影面为与其等效的平面地受力迎水面。导向舵板的受力迎水面的形状可以为矩形,也可以为圆角矩形、三角形、梯形、半圆形、腰圆形、环形、扇形、扇环形或不规则形状,对于为圆角矩形、三角形、梯形、半圆形、腰圆形、环形、扇形、扇环形或不规则形状的平面地受力迎水面也可以用上述的微积分方程或有限元法求出其等效矩形平面的受力迎水面。由此,对于任意形状的导向舵板的受力迎水面均可以找到一个与其等效的等效矩形平面的受力迎水面,然后可以根据该等效矩形平面的受力迎水面,通过应用前述的方法判断选择合适位置的定位环与救援绳相连。一般地,只要受力迎水面的矩形平面具有100平方厘米以上的面积,本发明的绳控水上救生装置即可工作。导向舵板的受力迎水面的面积越大,其接受水流的冲击力越大。在洪水中,过大的受力迎水面的面积(如大于5000平方厘米)可能造成救援绳拉力过大而绷断或者把救援者拉入水中。优选地,导向舵板的受力迎水面为平面,面积为200平方厘米至5000平方厘米。其中,面积在1000平方厘米以下的小受力迎水面面积的导向舵板用于洪水等急流情况下,其救援可减少救援绳的拉力;面积在2000平方厘米以上的大受力迎水面面积的导向舵板用于平缓水流及静水水域救援。更优选地,导向舵板的受力迎水面的面积在1000至2000平方厘米,其可适用于水流速度0.2-2米/秒的大多数情况下救援。
在第八个实施例中,本发明的绳控水上救生装置的救援绳的一端设置有安全钩(第一安全钩),另一端用于供救援者握持,在两端的中间,即绳身上也设置有一个安全钩(第二安全钩);救生浮体本体的侧部至少设置两个定位环,分别为第一定位环和第二定位环;第一安全钩和第二安全钩之间的救援绳长度大于第一定位环和第二定位环的距离。可以知道,当将救援绳上的第一安全钩与第一定位环(或第二定位环)配合,第二安全钩与第二定位环(或第一定位环)配合时,第一安全钩和第二安全钩之间的救援绳呈松弛状,救援绳对救生浮体本体的拉力的作用点在第二定位环(或第一定位环)处;继而当解除第二安全钩与第二定位环(或第一定位环)的配合时,救援绳对救生浮体本体的拉力的作用点转变为第一定位环(或第二定位环)处。由此,本实施例中的绳控水上救生装置不仅适用于将救生浮体本体浮航到被救援者处,还适合于将救生浮体本体带着被救援者拉回到救援者处,具体的使用方法如下:
步骤一、救援者根据被救援者相对于自己的位置和水流的方向,将第一安全钩与第一定位环或第二定位环配合,并且将第二安全钩与第二定位环或第一定位环配合。救援者判断选择合适位置的定位环以与救援绳上的第二安全钩配合的方法与第一个实施例中描述的绳控水上救生装置的使用方法中的步骤一内的判断方法相同。在此不赘述。然后将第一安全钩与第一定位环或第二定位环配合,优选地,与第一安全钩配合的定位环和与第二安全钩配合的定位环是关于导向舵板的受力迎水面的矩形平面的中心处的法线对称的。
步骤二、确定导向舵板相对于救生浮体本体的位置为绳控水上救生装置在水上使用时导向舵板相对于救生浮体本体的位置,即确定以可折叠的方式安装的导向舵板被打开到位,以可拆卸的方式安装的导向舵板被安装到位。
步骤三、抛投绳控水上救生装置,使救生浮体本体浮于水面且导向舵板浸没于水中。
步骤四、救援者释放救援绳,使绳控水上救生装置在水流的推动下向被救援者漂去。该步骤与第一个实施例中描述的绳控水上救生装置的使用方法中的步骤一内的判断方法相同。在此不赘述。
步骤五、被救援者抓住绳控水上救生装置后,解除第二安全钩与第二定位环或第一定位环的配合,即解除第二安全钩与和其相连的定位环的配合。此时的救援绳通过第一安全钩与第一定位环(或第二定位环)连接到救生浮体本体。在解除上述的安全钩和定位环的配合之前,被救援者可以先穿戴救生浮体本体,例如将作为救生圈的救生浮体本体套在身上。
步骤六、救援者回收救援绳,使绳控水上救生装置带着被救援者在水流的推动下向救援者漂回。
由此可见,本发明的绳控水上救生装置通过在救生浮体本体上设置导向舵板并将救援绳连接到救生浮体本体的合适位置处,能够利用水流的冲击力将救生浮体本体浮航到需要的水上位置以供被救援者抓取,本发明的绳控水上救生装置还可以利用水流的冲击力将救生浮体本体和被救援者拉回。本发明结构极为简单、成本极低且实施较方便,使用者个人即可灵活操作,具有极强的实用性。本发明应用范围广,在各种水流速度的水域均可使用。

具体实施方式
图1-3显示了第一个实施例中本发明的绳控水上救生装置,其包括救生浮体本体1、导向舵板2、第一定位环3、第二定位环4、救援绳6和安全钩5。本实施例中的救生浮体本体1是标准救生圈;导向舵板2固定设置在救生浮体本体1上,其是一个矩形平板,具有为矩形平面的受力迎水面;第一定位环3和第二定位环4分别设置在救生浮体本体1的侧部;救援绳6的一端设置安全钩5,并通过安全钩5与第一定位环3或第二定位环4的配合连接到救生浮体本体1,救援绳6的另一端供救援者握持。救生浮体本体1上还设置有位置可调节的定位环8,定位环8通过绑扣带7固定在救生浮体本体1的侧部。在调节定位环8的位置时,可以解除绑扣带7对定位环8和救生浮体本体1的绑扣,然后将定位环8放置到需要的位置,使用绑扣带7将定位环8和救生浮体本体1绑扣起来。
图4和5显示了在两种不同的水流方向的水域使用本发明的绳控水上救生装置的示意图,并显示了受力情况。图4对应的是左岸救援,图中的箭头表示水流方向,救援者20站在岸10上,手中握持救援绳6的一端,此时救援绳6连接的是第二定位环4。图中显示了救生浮体本体1受到导向舵板2的作用力f1、水流的冲力f2和救援绳6的拉力f3,可以看出,救生浮体本体1将在水流的推动下离岸漂航,救援者20通过控制救援绳,可以使救生浮体本体1漂航到被救援者处。具体地,如果被救援者位于水域中离岸10距离50米处的礁石上,救援者20站在距离被救援者约70~80米处的上游的岸10上,以小于水流流速的速度稳定地释放救援绳6,就可以快速投放救生浮体本体1到被救援者处。如救生浮体本体1到达离岸10距离50米处时处于被救援者的下游(或上游),救援者20可以在岸10上向水流的上游(或下游)的方向移动,例如奔跑,以调整救生浮体本体1的位置。
图5对应的是右岸救援,图中的箭头表示水流方向,救援者20站在岸10上,手中握持救援绳6的一端,此时救援绳6连接的是第一定位环3。图中显示了救生浮体本体1受到导向舵板2的作用力f1、水流的冲力f2和救援绳6的拉力f3,可以看出,救生浮体本体1将在水流的推动下离岸漂航,救援者20通过控制救援绳,可以使救生浮体本体1漂航到被救援者处。具体地,如果被救援者位于水域中离岸10距离50米处的礁石上,救援者20站在距离被救援者约70~80米处的上游的岸10上,以小于水流流速的速度稳定地释放救援绳6,就可以快速投放救生浮体本体1到被救援者处。如救生浮体本体1到达离岸10距离50米处时处于被救援者的下游(或上游),救援者20可以在岸10上向水流的上游(或下游)的方向移动,例如奔跑,以调整救生浮体本体1的位置。
在低流速或静水水域,救援者通过沿岸10奔跑可以造成救生浮体本体1和水的相对运动,起到与上述的左岸救援和右岸救援同样的效果。例如,当岸10右侧有较长的施救空间时,采用与上述的右岸救援时相同的方式连接定位环,救援者20在岸10上被救援者的右边80米处抛投救生浮体本体1入水,然后向左边一边奔跑一边释放救援绳6,当奔跑150米距离时救生浮体本体1大约离岸60米,继续奔跑,救生浮体本体1和救援者20之间的救援绳6将扫过被救援者,救援者20停止运动,被救援者抓住救援绳6,并顺着救援绳6抓住救生浮体本体1,这样救援者20就可把被救援者拉向岸10。
图6-10显示了第二个实施例中本发明的绳控水上救生装置,其导向舵板12是可折叠的。图6和7显示了导向舵板12闭合的状态,其贴合在救生浮体本体11上,较佳地,救生浮体本体11上具有凹槽,导向舵板12嵌入其中。图8和10显示了导向舵板12打开的状态。导向舵板12的一个端部通过铰链13连接在救生浮体本体11上,该端部还设置有突出部分16,两者之间连接有加强筋14以改善导向舵板12受力时的强度和刚度。救生浮体本体11上还设置有卡口15,导向舵板12打开到位后,卡口15咬合突出部分16,由此固定导向舵板12。另外,如图9给出的放大的示意图所示的,救生浮体本体11上的这个凹槽具有突出的边缘17,由此可以在导向舵板12闭合时限制导向舵板12,以保证导向舵板12在本发明的绳控水上救生装置不使用时处于闭合状态。
图11显示了第三个实施例中本发明的绳控水上救生装置,其导向舵板22是可拆卸的。导向舵板22具有契合于救生浮体本体21(本实施例中为标准救生圈)的底座23,底座23与导向舵板22之间具有加强筋24,底座23上连接有绑缚绑扣结构,具体地为绑带25和紧固扣26。优选地,底座23上有突起部27,例如定位钉或定位销,其可以嵌入在救生浮体本体21上的开孔以避免导向舵板22发生相对于救生浮体本体21的移动。
图12显示了第四个实施例中本发明的绳控水上救生装置,其导向舵板32是可拆卸的。导向舵板32具有两个突出部33,例如定位杆或定位榫,突出部33与导向舵板32之间具有加强筋34,在救生浮体本体31上相应地具有两个通孔35。通过将导向舵板32的突出部33插入救生浮体本体31上的通孔35中,并通过在突出部33的顶端露出通孔35的部位横向地插入定位销36,使导向舵板32相对于救生浮体本体31固定。
图13显示了第五个实施例中本发明的绳控水上救生装置,其导向舵板42是可拆卸的。导向舵板42具有契合于救生浮体本体41(本实施例中为标准救生圈)的底座43和契合于救生浮体本体21的夹持座45,通过螺杆44和夹紧螺母46把底座43和夹持座45牢固夹持于救生浮体本体41上,以使导向舵板42相对于救生浮体本体41固定。
图14显示了第六个实施例中本发明的绳控水上救生装置,包括四个可折叠的导向舵板52,每个导向舵板皆通过铰链54连接在救生浮体本体51上,救生浮体本体51上还相应地具有四个凹槽。处于闭合状态的导向舵板52嵌入凹槽55内,贴合于救生浮体本体51。救生浮体本体51的侧部还设置有两个定位环53。
图15显示了第七个实施例中本发明的绳控水上救生装置,其中的导向舵板62是弯曲的板,具有曲面的受力迎水面。导向舵板62设置在救生浮体本体61上,救生浮体本体61的侧部设置有定位环64,救援绳66通过安全钩65与定位环64的配合连接到救生浮体本体61上。使用时,救援者20站在岸10上,握持救援绳66的一端,通过控制救援绳66,使救生浮体本体61浮航到被救援者处。图中的箭头表示水流的方向,救生浮体本体61在水中受到导向舵板62的作用力f1、水流的作用力f2和救援绳66的拉力f3。其中,通过将曲面的受力迎水面的受力等效为平面的受力迎水面的受力,弯曲的导向舵板62可以被等效为平板的导向舵板621。
图16和17显示了第八个实施例中本发明的绳控水上救生装置,其包括救生浮体本体71、导向舵板72、第一定位环75、第一安全钩76、第二定位环73、第二安全钩74和救援绳77。实施例中的救生浮体本体71是标准救生圈;导向舵板72固定设置在救生浮体本体1上,其是一个矩形平板,具有为矩形平面的受力迎水面;第一定位环75和第二定位环73分别设置在救生浮体本体71的侧部;救援绳77的一端设置第一安全钩75,绳身设置第二安全钩74,通过第一安全钩75和/或第二安全钩74与第一定位环75和/或第二定位环74的配合连接到救生浮体本体71,救援绳77的另一端供在岸10上的救援者20握持。
图16和17显示了在箭头所示的水流方向的水域使用本发明的绳控水上救生装置的示意图,并显示了受力情况。图16显示的是投放救生浮体本体71,此时,第一安全钩76与第一定位环75配合,且第二安全钩74与第二定位环73配合,救援绳77对救生浮体本体71的拉力的作用点在第二定位环73处。救生浮体本体71受到导向舵板72的作用力f1、水流的作用力f2和救援绳77的拉力f3,在这些力的作用下漂离岸10。救援者20通过控制救援绳77,可以将救生浮体本体71浮航到被救援者处。
图17显示的是回收救生浮体本体71,被救援者抓到救生浮体本体71后,解除第二安全钩74与第二定位环73的配合,保留第一安全钩76与第一定位环75的配合,此时救援绳77对救生浮体本体71的拉力的作用点在第一定位环75处。救生浮体本体71受到导向舵板72的作用力f1、水流的作用力f2和救援绳77的拉力f3,在这些力的作用下漂向岸10。救援者20通过控制救援绳77,可以将救生浮体本体71连带被救援者拉回到岸10。
当使用本发明的绳控水上救生装置的水域的水流方向与图16和17所示的相反时,可以相应地调整第一定位环75和第一安全钩76与第二定位环73和第二安全钩74的配合方式。具体地,投放救生浮体本体71时,将第一安全钩76与第二定位环73配合且将第二安全钩74与第一定位环75配合;回收救生浮体本体71时,被救援者解除第二安全钩74与第一定位环75的配合而保留第一安全钩76与第二定位环73的配合。
以上详细描述了本发明的较佳具体实施例。应当理解,本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此,凡本技术领域的技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应在由权利要求书所确定的保护范围内。
