Description

喷射流体集束推进器
技术领域
本发明是有关于一种喷射流体集束推进器，尤指一种由管内壁的螺旋或直线导流凸 片或导流凹槽， 增加流体的磨擦力， 使得原来呈散开疏松的流体， 在受到加压或旋转、 挤压时， 可扭结成集束状， 该集束状流体可产生强大的推进力。 背景技术
船舶靠着引擎及螺旋桨推进，但是螺旋桨的空蚀现象往往造成螺旋桨空转而拖慢船 速。 依 "伯努利原理"， 螺旋桨转速越快水流压力就越小， 水流也因此产生汽化现象， 当螺旋桨叶片表面压力低于海水蒸气压时， 会产生"螺旋桨空蚀"现象， 叶片所带出的 气泡是造成船只震动与噪音的主因， 而气泡破裂情况严重会造成螺旋桨效率下降， 螺旋 桨空转而拖慢了船速， 甚至使得螺旋桨叶片产生如齿轮状的麻点， 造成螺旋桨损坏。
同时， 传统式螺旋桨推进器在旋转时， 叶片后方会产生阻力面及拖力面， 使得船速 下降， 螺旋桨的叶面大小， 除了与推力大小有关之外， 也同时形成船舶的阻力面与拖力 面， 从而抵消了船只部份速度。 此外， 螺旋桨易被水中杂物缠绕或撞击， 使得螺旋桨易 损毁。
已知国际专利公告 EP0 334737 "Rotary non-positive machine"以螺纹状螺旋 桨叶片结构， 虽可加强水流并改善所产生的阻力及拖力， 但是终究还是螺旋桨及叶片的 结构， 无法克服上述 "伯努利原理"所产生的种种不良现象。
现今较为先进的喷水推进器 （JetPropulsor), 其主要的改良是将传统式螺旋桨推进 器改装在管内； 由于螺旋桨在管内， 所以螺旋桨所产生的流体阻力与拖力可降至最小， 使得推进速度提髙。 但是喷水推进器仍然使用螺旋桨， 易为杂物缠绕， 无法克服 "伯努 利原理 "所产生的现象， 也仍然无法完全解决阻力与拖力的问题； 喷水推进器无法使用 较长的管筒， 因此无法制造更大的压力使得推进效能增高。
已知国内专利 5 72 842、 5475 73、 52 86 9 9、 33 9 756 , 以及 美国专利 US 0 0 5 1 8 1 86 8 A> US 0 0 5 0 8343 5 A均以不同的巧思建构了 不同功能的推进器， 但是因为仍然使用螺旋桨， 所以无法解决上述已知技术的问题。 发明内容
本发明喷射流体集束推进器的设计， 在装置内壁设计螺旋或直线集束导流凸片或导 流凹槽， 以增加流体的磨擦力， 使得原来呈散开疏松的流体， 在受到加压或旋转、 挤压 时， 可扭结成集束状， 该集束状流体可产生强大的推进力； 同时， 因为此集束流体所含 空气量较少， 气泡磨擦力较小， 故而大幅度降低噪音。 由于本发明不采用传统式螺旋桨 当作推进装置， 所以不会产生 "伯努利原理"所造成的空蚀现象， 也无流体的阻力及拖 力的问题， 因此使得推进力大幅度增加。
本发明目的之一在于提供一种由管内壁螺旋或直线导流凸片或凹槽， 使流体在受到 加压或旋转或挤压时， 可扭结成集束状， 以产生强大推进力及久聚不散的喷射流体集束 推进器。

本发明目的之一在于提供一种喷射流体集束推进器的流体调压器， 以调整管内流体 向外流出的压力。
本发明目的之一在于提供一种喷射流体集束推进器的滚轴装置，使得导流集束中空 管， 得以滚动， 并确保喷射流体集束推进器正常运作。
本发明目的之一在于提供一种喷射流体集束推进器的分流转向器装置，使流体产生 向左、 向右、 向前等不同方向的流动， 进而达到喷射流体集束推进器的转向动作。
本发明目的之一在于提供一种喷射流体集束推进器的反向推力装置，方便船舶需要 倒车时使用， 使得流体完全改变原来的行进模式， 产生反射后的反向推力动作， 达到倒 车的目的， 其反射后的流体不会产生回头冲堵现象降低推力效能。
本发明目的之一在于提供一种隐藏式又可多处布建于船底的喷射流体集束推进器， 善加运用滚筒式与加压式喷射流体集束推进器的特征与隐藏式的优点，混合布建于船底 各处， 以分散船舶的动力源， 并可引进较具环保概念的油、 电引擎机组相互运用， 使得 各部动力引擎机组可依实际需求或动能状态使用， 以避免引擎机组过度运作造成损伤， 达到最佳的航运经济效能。 本发明目的之一在于提供一种可应用于消防管滚筒式喷水头装置、消防管加压式喷 水头装置、 液体或气体输送管加压装置、 流体强力吸出管装置 （如马桶装置）， 以大幅 增加其流体流动效能的喷射流体集束推进器。
本发明目的之一在于提供一种由加压装置， 配合管内壁螺旋或直线导流凸片或凹 槽， 以及前宽后窄或直筒的中空管状体， 以产生强大推进力的喷射流体集束推进器。
本发明目的之一在于提供一种具有集束流体功能以产生强大推进力、解决因传统式 螺旋桨造成的气泡所产生的震动及噪音问题， 以及解决因传统式螺旋桨所形成的 "螺旋 桨空蚀伯努利现象"的多功能喷射流体集束推进器。
根据本发明所实施的喷射流体集束推进器的优点包含如下：
(一） 经济效益： 船舶速度及货物承载量两者兼顾
1、 由于喷射流体集束推进器不须如螺桨所需的大空间， 推进器的位置可重新设计 布置， 以增加置放货物的空间。
2、 一般而言， 船弦的稳定翼加大， 其速度减缓， 但因喷射流体集束推进器的速度 效能高， 因此一旦加大船弦的稳定翼， 其船舶速度仍然可以提高。
目前使用螺旋桨的船舶只能就上述速度及承载量二选一。
(二）节省维修保养方面的成本
1、 喷射流体集束推进器乃属隐藏式推进器装置， 置于船舱内的底部， 整体动力推 进系统不外露， 较不易受到外力损伤， 且因维修时不必进船坞， 可节省大量时间和金钱 成本。
2、 喷射流体集束推进器具有多层滤网装置， 且其管筒为中空， 可改善螺桨易于被 杂物缠住或碰撞毁损的缺点。
3、 喷射流体集束推进器采模块化结构性设计， 因此可依各种不同船舶所需动力的 需求， 设计成 "主动力"或 "辅助动力"系统。
4、 喷射流体集束推进器釆模块化式设计， 装拆维修更新简单， 因此一旦受到海中 生物粘着时， 可以拆卸方式清理或维修， 不必特别雇人下水处理。
(三） 能源耗用： 喷射流体集束推进器可采油电混合使用低速时用电， 中、 高速时 用油， 可节省石油能源。
(四） 推进动力不须集中于一处
1、 喷射流体集束推进器采船底多处分段式布建， 其动力不集中于船尾一处， 可采 分散动力的方式让船体的推力平均 （主动力与多具辅助动力）， 以避免引擎负荷过重导 致故障或降低效率。 其概念如同四轮传动的汽车因动力分散， 是故其在低速、 越野及爬 坡时的动力较二轮传动车为佳。
2、 喷射流体集束推进器可 动力需求采混合方式布建， 如滚筒式或加压式等多种 不同的型式及马力， 以求其最适性。
3、 亦可视船舶的长短、 载重量的大小， 分别在船舶左、 右船舷的吃水线下， 依转 向的动力需求， 装置一个或数个本推进器装置。
(五） 噪音较低喷射流体集束推进器因所产生的气泡量极微， 因此其噪音较低。
(六）管内不会出现压力过高及反压、 逆流等效应， 由于管筒呈头大尾窄的中空管 状体， 管内壁上为螺旋状导流片而非螺旋桨叶片， 流体在一定管内压力下， 形成集束流 体自管尾喷出，因此管筒在高速旋转时，管内不会出现压力过高及反压、逆流等的效应， 进而影响到推力。
(七） 螺旋桨的空化现象不易产生
1、 筒内流体经扭结或视需求给予外部加压后， 所形成的压力高于海水蒸气压力。
2、 管内螺旋状导流片和流体的接触面， 并非如螺桨叶片表面的以点接触， 而是从 头到尾的和螺旋线全面接触， 再加上管内的压力高于海水蒸气压力， 因此空化现象不易 产生。
( Λ)船底水漂现象， 可减少船底的磨擦阻力、 提高航速， 加压式 （或滚筒式） 置 于船底， 除产生推进力之外， 尚可在船底产生水漂现象， 如此将减少船底与流体间的磨 擦力， 有利于航速的提高。
. (九） "集束状导轨流体"形成强力喷射流体动力， 喷射流体集束推进器不是以螺 旋桨为推力来源， 而是透过滚筒内的螺旋状导流片的滚动， 将流体滚动扭结成一股加压 后的 "集束状导轨流体"， 经反射力的原理， 而产强力的喷射流体动力。
(十）可提升推进效率 "集束状导轨流体"推力， 可聚久不散， 其推力大于螺桨散 状推力。
(十一）船舶的流线型设计， 喷射流体集束推进器隐藏在船舱底部， 因此其船舶整 体造形可朝流线型方向设计，以符合船舶运动时的流体力学；亦可强化船舶的扭力强度， 增强船舶的结构体。
(十二） 效能优于 Water Jet及传统螺旋桨； Water Jet管筒短， 可制造的压力较小， 且不是中空管无法将流体集束， 螺旋桨叶片易为杂物缠住， 其效能自然远不如管筒长， 且为中空管的喷射流体集束推进器。 (十三） 螺旋桨及 Water Jet无法克服的伯努利现象， 喷射流体集束推进器视需求 可将流体经由外部加压后送至中空管内， 让管内的流体压力尽量保持高于海水蒸气压 力， 所以就可以克服伯努利现象， 并增加转速及其推进力。
本发明提供一种滚筒式喷射流体集束推进器， 包含- 一导流集束中空管，具有导流结构在其内壁且该中空管为前宽后窄端的内径或前后 同宽的内径； 及
一驱动装置， 用以驱动该导流集束中空管旋转， 以使该导流结构可使管内流体扭结 成集束状， 并形成管内压力， 用以产生推进力。
由管内壁的螺旋状导流凸片或导流凹槽的导流结构， 可增加流体的磨擦力， 经过一 种驱动装置的动力转动， 或导入加压后的流体， 使得原来呈散开疏松的流体， 在受到旋 转及挤压时， 可将管内的流体扭结成集束状， 并形成管内压力， 因而该集束状流体可产 生强大的推进力； 同时， 因为此集束流体所含空气量较少， 气泡磨擦力较小， 故而大幅 度降低噪音。 由于本发明不采用传统式螺旋桨当作推进装置， 所以能够克服 "伯努利原 理"所造成的空蚀现象， 也无流体的阻力及拖力的问题， 因此使得推进力大幅度增加。

请参考图 1，是显示本发明喷射流体集束推进器 1 0 0的导流集束中空管的示意图 与剖面图。该导流集束中空管 1 0的内径为前宽后窄， 以加强流体通过时在中空管 1 0 的中心呈集束作用， 如虚线所示位置处； 管壁 1 2具有一或复数管内壁导流凸片 1 5 。 在本发明的一种实施例中， 该管内壁导流凸片 1 5呈螺旋状， 用以在该导流集束中空管 1 0受到旋转时， 在管内中心处产生螺旋集束流体； 而在管内壁导流凸片 1 5的表面上 具有一或复数个凸条 1 4， 以加强流体经过时的扭结集束力。在本发明的另一种实施例 中， 该管内壁导流凸片 1 5呈直线状， 用以在流体受到加压或挤压时， 产生直线集束流 体。
请参考图 2，是显示使用本发明喷射流体集束推进器 1 0 0的推进气箱 9 4及推进 器舱 9 5的图与该导流集束中空管模块结构的图。在本发明的一种实施例中， 喷射导流 集束推进器装置 1 0 0安装在推进器箱 9 4内，而推进器箱 9 4则组装在推进器舱 9 5 内.； 推进气箱 9 4是用来装置、 保护及检修喷射导流集束推进器装置 1 Q 0之用。 推进 器舱 9 5经加压后可让舱内压力同等于海平面的大气压力，如此当推进气箱 9 4与推进 器舱 9 5安装于船舱内部底层时， 位在船底部的海水就不会溢到舱内， 以便打幵推进气 箱 9 4，在船舱内进行各种喷射导流集束推进器装置 1 0 0的维护、检修、保养等工作， 而不必派员至船外吃水线下或须等进船坞后才能处理，可为业者节省船舶进船坞的次数 及维修时间与费用，亦可省去进船坞后停止营运的各种损失。可视船舶的大中小型船体、 吨位与船舶的吃水深度， 而决定是否需设推进器舱 9 5 , 但是推进气箱 9 4的装置则是 有其必要性。
导流集束中空管模块结构设计， 使得导流集束中空管 1 0的产制与维修较为便捷、 省时； 本发明导流集束中空管模块结构设计是在模块 9 0与模块 9 0之间放置垫圈片 9 1， 再以螺丝 9 2锁紧， 以结合不同的模块而组成一导流集束中空管 1 0。 在此一实施 例中， 导流集束中空管 1 0例示性地由三个导流集束中空管模块 9 0组成， 以方便组装 及维修； 在导流集束中空管模块 9 0上至少有一个清理盖 9 3， 可随时掀盖进行维护或 清理导流集束中空管 1 0， 以保持最佳的运作状况。
请参考图 3，是显示本发明喷射流体集束推进器 1 0 0的导流集束中空管 1 0与转 向器装置 2 0的结合图及该转向器装置 2 0的侧视图。该转向器装置 2 0的前后各有一 个转向衔接页片框 2 1， 以连结转向衔接页片 2 2， 形成一可弯折的中空管； 一或复数 个伸缩杆器 2 3置于转向器装置 2 0前端， 用以牵动本装置 2 0的尾端出口的左右转 向； 在此一实施例中， 导流集束中空管 1 0的尾端与转向器装置 2 0的前端相连结， 利 用伸縮杆器 2 3的伸缩功能， 以及一或复数个转向衔接页片 2 2所形成的弯折管， 牵动 转向器装置 2 0运作， 使得该折管成为弯状， 而达到左右转弯或方向控制的目的。' 请参考图 4， 是显示本发明喷射流体集束推进器 1 Q 0的流体调压器 3 0的结构 图。流体调压器 3 0具有一或复数个伸缩杆器 2 3以及一或复数个调压页片 3 1； 在此 一实施例的显示中， 导流集束中空管 1 0与转向器 2 0相连结之后， 再与一流体调压器 3 0相连结， 在导流集束中空管 1 0的管壁 1 2内装置伸縮杆器 2 3， 以调控调一或复 数个压页片 3 1的张縮功能， 如此即可形成管内流体向外流出的压力， 当调压页片 3 1 逐渐下压时会形成管口缩小， 一旦管内压力大增， 流体向管外喷出产生高速流体， 反之 当调压页片 3 1回升时， 管内压力不大， 流体向外喷速渐弱而产生低速， 其中管壁 1 2 内的该等箭头表示导流集束中空管 1 0的流体的螺旋状导流方向，并藉由流体调压器 3 ◦来提升螺旋状集束流体的推力。 如此在同一管内的流体， 因管口大小造成管内不同的 压力值， 而形成流体喷出速度的高低不同。
请参考图 5， 是显示本发明喷射流体集束推进器 1 0 0的导流集束中空管与转向 器、 流体调压器的结合图与管内集束流体的示意图。 在此一实施例中， 该导流集束中空 管 1 0可结合至少一个转向器 2 0或是一般的方向舵， 以改变方向； 以及至少一个流体 调压器 3 0 , 调整流体流出时的压力大小，一旦在管内形成的螺旋状集束流体流出管外 时， 即形成集束状导轨流体， 而产生高效能推力。 其中， 图 5下方的管内集束流体的示意图， 斜线表示导流集束中空管 1 0被驱动旋 转使管内流体呈螺旋状流体， 而中心虚线则为产生螺旋状集束流体的推力及其方向。 在 前宽后窄的内径中， 流体经过螺旋式导流集束中空管 1 0的旋转后， 含气量少， 而形成 一集束状流体的结构， 呈导轨流体， 使其推力大增且寂静无声。
请参考图 6 A与图 6 B， 是显示本发明喷射流体集束推进器 1 0 0的滚轴装置的结 构图。 螺旋式导流集束中空管 1 0需要滚动才能产生集束状流体的动能， 因此导流集束 中空管 1 0的管外需要加装滚轴装置 1 1 0以便能滚动； 在此一实施例中， 将本发明应 用于船舶推进， 可用螺丝 9 2锁住 U型滚轴固定基座 1 1 1并固定在船舶底部， 然后用 螺丝 9 2将固定式滚轴固定支架 1 1 2固定在 U型滚轴固定基座 1 1 1上，另利用活页
1 1 4连结可掀式滚轴固定支架 1 1 3， 以及可掀式滚轴固定支架密合夹器 1 1 5， 而 形成滚轴固定支架 4 4 (如图 7所示）。 '
固定式滚轴固定支架 1 1 2具有一或复数个滚轴固定架座 1 2 0；滚轴固定架座 1
2 0上端连结橡胶滚轴 1 2 1， 以托起导流集束中空管 1 0， 并使其得以滚动。 可掀式 滚轴固定支架 1 1 3亦具有一或复数个加压器 1 2 4；加压器 1 2 4连结橡胶滚轴 1 2
1， 以夹紧及固定导流集束中空管 1 0， 并使其得以滚动。 当橡胶滚轴 1 2 1经长时间 滚动而产生磨损时， 仍然可利用加压器 1 2 4的加压， 使得导流集束中空管 1 0旋转时 保持中心点稳固， 不会发生偏斜抖转或转动效能降低， 或造成其它机械故障的现象。
另外利用螺丝 9 2将滚轴固定环 1 2 3及 V型滚轴垫 1 2 2锁在导流集束中空管 1 0管外壁上， 使得 V型滚轴垫 1 2 2与滚轴装置 1 1 0的胶滚轴 1 2 1相密合。 V型 滚轴垫 1 2 2设计的主要目的， 是使得导流集束中空管 1 0在高速滚动时， 永远保持固 定在此凹槽中滚动， 在滚动时不会发生跑位或偏移现象， 以确保喷射流体集束推进器 1 0 0正常运作。
再请参考图 6 B， 杂物铲清器 1 3 0装置在滚轴固定支架 4 4内侧， 其主要的目的 是铲除留在 V型滚轴垫 1 2 2上附着的杂物，使导流集束中空管 1 0在滚动时不会因异 物碰撞产生跳动， 或是损伤胶滚轴 1 2 1而降低运作效能。 当导流集束中空管 1 0高速 滚动时， 会卷动滚轴装置 1 1 0内的流体， 使得杂质到处流窜或碰撞， 影响导流集束中 空管 1 0的效能， 所以杂物铲清器 1 3 0会在导流集束中空管 1 0滚动时， 会铲除 V型 滚轴垫 1 2 2上附着的杂物， 同时抽水帮浦 1 3 4也会激活， 将滚轴装置 1 1 0内的流 体向外抽， 以将流体中的杂物透过杂物导入器 1 3 1的引导， 将杂物引入杂物留置网 1

请参考图 8，是显示本发明喷射流体集束推进器 1 0 Q的滚筒式推进装置的实施例 之二的示意图。 该滚筒式喷射流体集束推进器 5 0 , 包含： 置于滚筒式导流集束中空管 3 5的驱动装置 4 1， 该驱动装置直接带动滚筒式导流集束中空管 3 5； 在此一实施例 中，流体由滚筒式导流集束中空管 3 5的侧面开口注入，并以进水口滤网 4 8过滤流体； 该滚筒式导流集束中空管 3 5的内径为前宽后窄， 因此在接受动力后， 可加强流体的集 结力量；而其管内壁一或复数个螺旋状管内壁导流凸片 1 5，使流体在受到旋转及 /或挤 压时， 扭结成集束状， 再经转向器 2 0、 流体调压器 3 0， 以产生强大推进力； 滚轴固 定支架 4 4则将滚筒式导流集束中空管 3 5固定在滚筒外壳 4 5内； 加压管入口 4 9用 于当滚筒式喷射流体集束推进器 4 0需要外部加压时使用。
请参考图 9，是显示本发明喷射流体集束推进器 1 0 0的滚筒式推进装置的实施例 之三的示意图。 该滚筒式喷射流体集束推进器 6 0， 包含： 置于滚筒式导流集束中空管 3 5前端的驱动装置 4 1，该驱动装置 4 1经万向接头器 5 1直接带动滚筒式导流集束 中空管 3 5； 在此一实施例中， 流体由滚筒式导流集束中空管 3 5的前端开口注入， 并 经进水口 4 6、 以进水口挡网 4 7、进水口 4 6经进水口挡网 4 7及进水口滤网 4 8过 滤流体； 该滚筒式导流集束中空管 3 5的内径为前宽后窄， 因此在接受动力后， 可加强 流体的集结力量； 而其管内壁一或复数个螺旋状管内壁导流凸片 1 5， 使流体在受到旋 转及挤压时， 扭结成集束状， 以产生强大推进力。 滚轴固定支架 4 4则将滚筒式导流集 束中空管 3 5固定在滚筒外壳 4 5内；加压管入口 4 9用于当滚筒式喷射流体集束推进 器 4 0需要外部加压时使用。 请继续参考图 1 Q， 是显示本发明喷射流体集束推进器 1 0 Q的加压式推进装置的 实施例之四。 该加压式喷射流体集束推进器 7 0， 包含： 加压流体储存槽 7 1， 可提供 加压之后的流体； 该加压流体储存槽 7 1具有一压力安全气阀 8 0 , 当加压流体储存槽 7 1所储存的流体压力过大时，将由压力安全气阀 8 0将过多的 力释出，以确保安全; 且该加压式喷射流体集束推进器 7 0经由信道管 7 5、压力输出幵关阀 7 6、 反逆流开 关阀 7 7及加压流体输送槽 7 9， 将加压流体输送至固定式导流集束中空管 2 5， 该加 压流体输送槽 7 9为固定式导流集束中空管 2 5的缓冲及固定装置；而该固定式导流集 束中空管 2 5的内径为前宽后窄， 可加强流体的集结力量， 且连结转向器 2 0及流体调 压器 3 0 , 以产生最适合需求的流体推进力。
在此一实施例中， 液体经进水口 4 6、 进水口挡网 4 7、 进水口滤网 4 8过滤， 或 者气体经空气滤清器 7 8过滤后， 可由信道管 7 5进入本装置， 因此可由流体切换器 7 4视环境选择 /切换液体或空气的进入；流体进入本装置后，经流体进量控制器 7 3及增 压器 7 2增压处理后， 即进入加压流体储存槽 7 1储存； 加压流体储存槽 7 1保持一定 量的加压流体储存， 以实时供应加压式喷射流体集束推进器 7 0的需求； 同时也可视需 要提供滚筒式喷射流体集束推进器 4 0 / 5 0 / 6 0的加压流体。
请参考图 1 1 A、 图 1 1 B 与图 1 1 C， 是显示本发明喷射流体集束推进器 1 0 0 的分流转向器装置的结构图。在此一实施例中， 流体经由信道管 7 5后会受到分流切换 板 2 4 0的不同置放位置， 使流体产生向左、 向右、 向前等不同方向的流动， 进而达到 喷射流体集束推进器 1 0 0的转向动作。 参考图 1 1 A所示， 当要向右转时， 转向器 2 1 0会向左转动分流转向筒 2 2 0，而在分流转向筒 2 2 0内的左边分流切换板操控线 起点端 2 6 0 , 会牵动分流切换板操控线 2 5 0， 经过分流切换板中心点 2 3 0及右边 的分流切换板操控线终点端 2 7 0后， 会自动拉动分流切换板操控线 2 5 0 , 将分流切 换板 2 4 0向右拉动到达分流切换板操控线终点端 2 7 0的位置， 因此流体经由信道管 7 5进入后经分流切换板 2 4 0的阻挡， 就会由右边的分流转向筒 2 2 0内向左喷出， 而达到右转的目的。 反之若要左转， 参考图 1 1 B所示， 只要将转向器 2 1 0转向右边 即可， 其过程相同不在此重述。
请参考图 1 1 C所示， 另当要向前时， 只要将转向器 2 1 0转至中间处， 让分流切 换板 2 4 0停在中间位置， 如此就可以达到向前喷出的目的。 本分流转向器装置 2 0 0 较适合用于加压式喷射流体集束推进器 7 0转向之用，可用于当辅助推进器或倒车或减 速或船舷两侧的转向器。 请参考图 1 2 A、 图 1 2 B、 图 1 2 C、 图 1 2 D， 是分别显示本发明喷射流体集束 推进器 1 0 0的船舶外其它应用的示意图。在各种不同的实施例中， 本发明尚可应用于 消防管滚筒式喷水头装置 6 0 0 (如图 1 2 A所示）、 消防管加压式喷水头装置 6 5 0 (如图 1 2 B所示）、 液体或气体输送管加压装置 7 0 0 (如图 1 2 C所示）、 流体强力 吸出管装置 7 5 0 (如图 1 2 D 所示）； 其各应用的组件连结关系和前述相关组件的连 结相同， 在此不再赘述。
请参考图 1 3 ,是显示本发明喷射流体集束推进器 1 0 0的反向推力装置的示意图 与实施例一的结构图。 在此实施例中， 将反向推力 （倒车 /减速）装置 3 0 0安装在船 尾近喷射流体集束推进器 1 0 0的后方处， 当船舶需要倒车或减速时， 利用伸缩杆器 2
3将反向推力板 3 1 0徐徐放下； 由于反向推力板 3 1 0近喷射流体集束推进器 1 0 0 喷出流体面， 具有双凹圆弧形向外侧流动的设计， 所以当所喷出的流体经反向推力板 3
1 0的反射后， 其流体完全改变原来的行进模式， 产生反射后的反向推力动作， 达到倒 车或减速的目的。由于反向推力板 3 1 0的设计是由中心点内向外呈双凹圆弧状向外侧 流动， 因此反射后的流体不会产生回堵现象而降低推力效能。
请参考图 1 4 A、 图 1 4 B， 是显示本发明喷射流体集束推进器 1 0 0的反向推力 (倒车 /减速）装置的示意图与实施例二的结构图。 在此实施例中， 将反向推力 （倒车
/减速）装置 3 5 0安装在船尾近喷射流体集束推进器 1 0 0的后面相连接， 当船舶需 要倒车或减速行驶时， 中空管体 3 5 5两侧的反向推力板 3 6 5， 经后端的伸缩杆器 2
3的伸出， 带动反向推力板 3 6 5 CB) 端向中空管体 3 5 5的中心移动， 然后再以轴 心 3 6 0为中心点， 于是反向推力板 3 6 5 (A) 端就随着伸缩杆器 2 3的所伸出的距 离长短， 而让两侧反向推力板 3 6 5张开不同大小的角度， 让流体从中空管体 3 5 5两 侧开口处向管外流出， 而改变原先流体的流向及流量大小。 由于伸缩杆器 2 3的伸出会 使得反向推力板 3 6 5 (B) 端渐接近中空管体 3 5 5的中心位置， 因此原本直线流出 的流体受到两侧反向推力板 3 6 5 (B) 的向内挤压， 于是就会迫使流体由中空管体 3
5 5两侧的反向推力板 3 6 5 (A) 端开口处， 顺着向推力板 3 6 5的张开角度大小， 而改变原流体的流向及流量大小， 转而向前流出， 如此就可以简单的装置， 而达到反向 推力的目的， 因此就可有效做到船舶倒车或减速行驶的功能。
图 1 5 A、 图 1 5 B、 图 1 5 C 显示本发明喷射流体集束推进器的船底布建结构图 以及引流切板装置与流体阻力装置图。 在图 1 5 A的实施例中， 喷射流体集束推进器 1
0 0可多处布建于船底， 且具隐藏性； 本发明可善加运用滚筒式与加压式喷射流体集束 推进器的特征与隐藏式的优点， 混合布建于船底各处， 以分散船舶的推进动力源， 并可 引进较具环保概念的油、 电引擎机组相互运用， 使得各部动力引擎机组可依实际需求或 动能状态使用， 以避免引擎机组过度运作造成损伤， 达到最佳的航运经济与环保效能。
请继续参考图 1 5 B及图 1 5 C, 为配合本发明装置， 其船底设计具有引流切板装 置 4 0 0， 以及流体阻力装置 5 0 0的特殊结构。 当高速运转时喷射流体集束推进器 1 0 0需要大量流体进入时， 引流切板装置 4 0 0可满足其需求； 在船底的进水口管处后 方可装置引流切板 4 1 0，经伸缩杆器 2 3的伸张后，可将引流切板 4 1 0自船底伸出， 其与船底的流体产生斜切面， 因此经流体经引流切板 4 1 0导引，将船舶外的流体经进 水口大量引入管内， 而达到大量引流的目的。 当不需引流时， 可将引流切板 4 1 0透过 伸缩杆器 2 3缩回即可。
当船舶需要减速时， 可利用流体阻力装置 5 0 0 , 而达到减速的效能， 是为有效的 煞车辅助器。船舶可视实际需求于船底或船舷两侧， 装置一或复数个流体阻力装置 5 0 0， 透过伸缩杆器 2 3的伸张， 可将流体阻力板 5 1 0张开， 以增加流体在流动时的阻 力面积， 进而达到减速的目的， 当船舶减速之后即可将阻力板 5 1 0缩回。
上述诸多实施例虽以应用于船舶为例， 但本发明不限使用于船舶， 亦可使用于水陆 两栖车辆、 水上娱乐机具、 帮浦、 引擎、 压缩机、 涡轮等， 凡是可由其促进推进力的设 备或装置。
在详细说明本发明的较佳实施例之后， 熟悉该项技术人士可清楚的了解， 在不脱离 下述申请专利范围与精神下可进行各种变化与改变， 亦不受限于说明书的实施例的实施 方式。
