【具体实施方式】
下面结合附图和实施例进行详细说明。 在附图中采用相同或者类似 的图标记来标示类似的部件, 为了筒洁起见, 有时同一部件在不同视图 中出现, 但是仅在某些视图中对其进行了标示。 为了表示方便, 图中的 侧壁、 分隔片以及壳体等构件均以线条表示。 并未显示其宽度或者厚度。
请参考图 1和图 2, 图 1是本发明的气压液压组合动力装置的一实 施例的结构示意图; 图 2是本发明的气压液压组合动力装置的另一实施 例的结构示意图。
如图 1所示, 在本发明的一实施例中, 气压液压组合动力装置主要 包括: 第一压力缸 110、 第二压力缸 120、 动力输出单元 200、 离心压力 泵 300、 气泵 400以及动力接收装置 500。 应当注意的是, 在本发明的实 施例中, 仅示出了两个压力缸来描述本发明的工作原理, 但压力缸的数 目并不限于此, 压力缸的数目可以是四、 五、 六、 七、 八个等, 多个压 力缸旨在形成交替做功系统, 以提供持续稳定的流体动力输出。
第一压力缸 110具有中空柱状结构且大致竖直设置,第一压力缸 110 的一侧设有第一流体出口 112和第一流体入口 113 , 第一流体出口 112 和第一流体入口 113进一步分别与第一流体出口通道 115和第一流体入 口通道 116流体连通, 第一流体出口通道 115通过导管与动力输出单元 200连通, 用于引导第一压力缸 110 内的压力流体来驱动动力输出单元 200, 第一流体入口通道 116通过导管与离心压力泵 300连通, 离心压力 泵 300在第一压力缸 110内没有压力流体时向第一压力缸 110提供压力 流体。
第一压力缸 110的另一侧设有第一气体出入口 114, 第一气体出入 口 114进一步与第一入气通道 117相连通, 第一入气通道 117通过导管 与气泵 400连通, 用于接收气泵 400提供的气压来推动第一活塞 111产 生液压动力, 以及用于在离心压力泵 300向第一压力缸 110提供压力流 体时排放气体(下文介绍) 。
第一活塞 111设于第一压力缸 110内, 将第一压力缸 110分隔成第 一气体腔室 1111 以及第一流体腔室 1112两个部分, 第一活塞 111 由于 流体和气体的推动作用而在第一压力缸 110内部往复运动, 第一流体入 口 113和第一流体出口 112与第一流体腔室 1112相连通,第一气体出入 口 114与第一气体腔室 1111相连通。
与第一压力缸 110类似, 第二压力缸 120亦具有中空柱状结构且大 致竖直设置, 第二压力缸 120的一侧设有第二流体出口 122和第二流体 入口 123 , 第二流体出口 122和第二流体入口 123进一步分别与第二流 体出口通道 115和第二流体入口通道 126流体连通, 第二流体出口通道 115通过导管与动力输出单元 200连通, 用于引导第二压力缸 120内的 压力流体来驱动动力输出单元 200, 第二流体入口通道 126通过导管与 离心压力泵 300连通, 离心压力泵 300在第二压力缸 120内没有压力流 体时向第二压力缸 120提供压力流体。
第二压力缸 120的另一侧设有第二气体出入口 124, 第二气体出入 口 124进一步与第二入气通道 127相连通, 第二入气通道 127通过导管 与气泵 400连通, 用于接收气泵 400提供的气压来推动第二活塞 121产 生液压动力, 以及用于在离心压力泵 300向第一压力缸 110提供压力流 体时排放气体(下文介绍) 。
第二活塞 121设于第二压力缸 120内, 将第二压力缸 120分隔成第 二气体腔室 1211以及第二流体腔室 1212两个部分, 第二活塞 121由于 流体和气体的推动作用而在第二压力缸 120内部往复运动, 第二流体入 口 123和第二流体出口 122与第二流体腔室 1212相连通,第二气体出入 口 124与第二气体腔室 1211相连通。
应当注意的是, 附图 1和附图 2中所示出的导管是分别从第一压力 缸 110和第二压力缸 120出来, 再合并起来一起与动力输出单元 200、 离心压力泵 300或气泵 400连通, 然而, 并不限于此, 在实际情况中可 采用各导管分别连通的方式。
在本发明的实施例中, 第一流体出口 112和第二流体出口 122产生 的压力流体用于驱动动力输出单元 200, 动力输出单元 200是一种增强 型动力输出装置 200, 该增强型动力输出装置 200包括动力轴 260 , 来自 第一流体出口 112和第二流体出口 122的流体驱动该增强型动力输出装 置 200 , 进而带动动力轴 260转动并对与其同轴的离心压力泵 300、 气泵 400以及动力接收装置 500做功, 动力接收装置 500可以是发电机、 发 动机曲轴等设备, 例如, 该动力轴为汽车发动机的曲轴。 进一步, 从增 强型动力输出装置 200的第三流体出口 214 (下文介绍)排出的流体 12 可以回流入流体容器 10内, 供循环使用, 节约资源。
如图 2所示, 在本发明的另一实施例中, 气压液压组合动力装置主 要包括: 第一压力缸 2110、 第二压力缸 2120、 动力输出单元 2200、 离 心压力泵 2300、 气泵 2400以及动力接收装置 2500。
类似于上述实施例, 第一流体出口 2112和第二流体出口 2122产生 的压力流体用于驱动动力输出单元 2200, 动力输出单元 2200是一种增 强型动力输出装置 2200,该增强型动力输出装置 2200包括动力轴 2260 , 来自第一流体出口 2112和第二流体出口 2122的流体驱动该增强型动力 输出装置 2200, 进而带动动力轴 2260转动并对与其同轴的离心压力泵 2300以及动力接收装置 2500做功, 动力接收装置 2500可以是发电机、 发动机曲轴等设备。 然而, 与上述实施例不同, 气泵 2400独立于该动力 输出单元 2200的动力轴 2260, 也就是说, 驱动气泵 2400所需要的动力 不再由动力输出单元 2200提供, 而是由发电机、 汽车电瓶等提供, 由此 可降低该气压水压组合动力装置的复杂程度, 从而增强该气压水压组合 动力装置的可靠性。 本实施例的另一个不同之处在于, 气缸内没有设置 活塞。 这是由于气体与液体可以自然地相互隔开, 所以还可以省掉活塞。 不过省掉活塞之后, 根据需要可以在气缸内设置感应器, 以感应液面的 位置, 进而控制各个气缸的工作进程。
需要说明的是, 本实施例是采用例如水的流体作为动力介质的。 但 是并不限于此, 比如可以采用蒸汽来作为介质。 则此时的流体供给单元 可采用蒸汽锅炉, 相应的动力输出单元可采用蒸汽发电机组等。
接下来, 请参照图 3 , 图 3是本发明一实施例的动力输出单元的结 构示意图。
动力输出单元 200是一种增强型动力输出装置 200, 该增强型动力 输出装置 200主要包括: 圓形腔体 210、 第三流体入口 212、 第三流体出 口 214、 主转轮 220、 叶轮 222、 外齿轮 230、 行星齿轮 240、 齿轮托架 250、 动力轴 260以及中心齿轮 270。
圓形腔体 210具有中空的圓柱结构, 该圓形腔体 210的上部设有第 三流体入口 212 ,第三流体入口 212上进一步设有第三流体入口通道 216, 该第三流体入口通道 216大致竖直设置, 使得进入圓形腔体 210的流体 具有一竖直入射角度, 因而能够更好的沖击叶轮 222以得到较大的初始 驱动力。第三流体出口 214设于圓形腔体 210的下部,第三流体出口 214 上进一步设有第三流体出口通道 218 , 流体 12从第三流体入口通道 216 进入圓形腔体 210沖击叶轮 222对其做功, 并随着叶轮 222转过一段圓 弧行程之后从第三流体出口通道 218排放回流入流体容器 10内,供循环 使用。
主转轮 220设于圓形腔体 210内部, 叶轮 222大致均勾设置在主转 轮 220的外圓周上, 叶轮 222具有中间下凹的圓弧状结构, 由此可将流 体的沖击力更有效的转换为驱动主转轮 220转动的驱动力。
外齿轮 230以预定距离间隔主转轮 220设置, 外齿轮 230的两端由 固定装置 (未示出) 固定, 外齿轮 230的内圓上设有轮齿 (未标识)。
动力轴 260设于外齿轮 230的中心处, 动力轴 260上设有中心齿轮 270, 动力轴 260与主转轮 220同步转动, 中心齿轮 270随着动力轴 260 一起旋转。
外齿轮 230与中心齿轮之间设有多个行星齿轮 240, 该多个行星齿 轮 240由齿轮托架 250固定连接, 每一行星齿轮 240均具有偏心结构, 即行星齿轮 240的一个半边相对于另一个半边较轻, 附图 2中用阴影部 分来表示较重的半边, 这种偏心结构可通将行星齿轮 240加工出一定空 间或在行星齿轮 240上附加配重块以及采用密度不同的两种材料来配置 行星齿轮 240的左右半边等方式来实现。
在本实施例中, 通过适当地设定中心齿轮 270、 外齿轮 230以及多 个行星齿轮 240的齿数, 可使得增强型动力输出装置 200的整个旋转部 分在旋转的任一时刻, 多个行星齿轮 240的整体重心均偏于旋转部分的 转动方向, 从而与流体的沖击力产生叠加效果, 使该增强型动力输出装 置 200具有较大的动力输出。
请参见图 4 , 其显示了增强型动力输出装置的另一结构类型, 在该 实施例中, 该增强型动力输出装置与上述实施例具有大致相同的结构, 其包括: 圓形腔体 410、 第四流体入口 412、 第四流体出口 414、 主转轮 420、 叶轮 422、 行星齿轮 440、 齿轮盘 450、 动力轴 460以及中心齿轮 470。 在本实施例中, 省去了上述实施例的外齿轮 230和齿轮托架 250, 而是采用齿轮盘 450进行替换, 齿轮盘 450相对固定, 该齿轮盘 450上 设有多个旋转轴 452, 多个行星齿轮 240设置在该多个旋转轴 452上, 当动力轴 460旋转时, 中心齿轮 470带动设于旋转轴 452上的行星齿轮 440绕旋转轴自转, 由于行星齿轮 440具有偏心结构, 所以各行星齿轮 440旋转时会产生促进旋转轴 460的惯性力, 进而增强该增强型动力输 出装置的动力输出。
接下来将描述与增强型动力输出装置 200同轴并由其驱动的离心压 力泵 300。
请一并参见图 5和图 6, 图 5是本发明一实施例的离心压力泵的外 部结构示意图; 图 6是本发明一实施例的离心压力泵的剖面示意图。
大体而言, 本发明一实施例的离心压力泵 300主要包括外壳体以及 旋转机构。 下面分别介绍二者的具体结构。
离心压力泵 300的外壳体主要包括: 第一侧壁 310、 第二侧壁 320 以及第一弧形壁 330。 该第一弧形壁 330显示为规则的一段圓周, 但是, 不受限于此, 根据需要, 此第一弧形壁 330也可为表面不规则的其他形 状的表面。
第一侧壁 310是具有一定厚度的板料, 其上设有第五流体入口 312, 该第五流体入口 312上进一步延伸有第五流体入口通道 314, 第一弧形 壁 330上设有第五流体出口 332, 该第五流体出口 332上进一步设有第 五流体出口通道 334, 第五流体出口通道 334通过导管接入第一压力缸 110和第二压力缸 120 ,以将离心压力泵 300产生的压力流体传输给第一 压力缸 110和第二压力缸 120。
第二侧壁 320是具有一定厚度的板料,第二侧壁 320与第一侧壁 310 具有相同的外围形状以及外围尺寸。 不同的是, 第二侧壁 320上设有轴 孔 322 , 轴孔 322上匹配设置有轴 7 机构 324, 轴 机构使用密封防水装 置保护, 以防止流体通过轴孔 322流出, 同时可延长轴承座和轴承的使 用寿命。
第一弧形壁 330也是具有一定厚度的板料, 第一弧形壁 330连接于 第一侧壁 310和第二侧壁 320的边缘,此三者固定连接形成圓形泵腔(未 标示 ) 。
下面请一并参见图 7和图 8 , 图 7是本发明一实施例的离心压力泵 的内部结构示意图; 图 8是本发明一例实施例的离心压力泵的的工作原 理示意图。
本发明一实施例的离心压力泵 300的旋转机构主要包括: 旋转压力 腔体 360和多个分隔片 370。
旋转压力腔体 360具有圓形中空结构, 该旋转压力腔体 360包括第 三侧壁 362和设于该第三侧壁 362边缘的第二弧形壁 364,第三侧壁 362 与第二弧形壁 364均是具有一定厚度的板料。 该第三侧壁 362以一定距 离与第二侧壁 320间隔开, 该第二弧形壁 364上设有若干开口 366。 旋 转压力腔体 360以一定距离间隔外壳体并形成环形集液通道 340。 第二弧形壁 364在与第三侧壁 362相对的一侧还具有收口部 3641 (参见图 5所标示)。 收口部 3641大致呈圓形, 且在圓形的中间具有中 心开口 (未标识 ) , 以便于来自第五流体入口 312的流体通过该中心开 口进入旋转压力腔体 360。 需要说明的是, 为了清楚显示内部结构, 在 图 6的剖面图中, 未显示第二弧形壁 364的收口部 3641。
在本的实施例中, 仅示意性地示出三个开口 366, 当然, 开口 366 的数量可以根据需要进行增加或者减少。 在优选实施例中, 该开口 366 上进一步设置有较短的导管 368 , 该导管 368倾斜设置以在旋转压力腔 体 360旋转时引导旋转压力腔体 360内的流体周向进入集液通道 340并 最终从第五流体出口 332排出。
增强型动力输出装置 200的动力轴 260的一端贯穿第二侧壁 320, 在本实施例中, 动力轴 260与第三侧壁 362 的外侧固定连接, 该固定连 接的可以采用螺丝、 焊接等方式实现。 也就是说, 当动力轴 260旋转时, 包括第三侧壁 362和第二弧形壁 364的旋转压力腔体 360在外壳体 310 的圓形泵腔内一同旋转。
分隔片 370分布式固定于旋转压力腔体 360的内部,每一分隔片 370 具有如图所示之适于产生离心势能的弧形状, 当然, 分隔片 370的形状 并不限于此, 还可以是其他形状。 分隔片 370固定于第二弧形壁 364上 的一端靠近相应的开口 366设置, 使得从该若干开口 366出来的流体具 有较大的势能。 在本实施例中, 仅示意性地示出三个分隔片 370, 当然, 分隔片 370的数量可以根据需要进行增加或者减少。 分隔片 370也是具 有一定厚度的板料, 分隔片 370将旋转压力腔体 360所包围形成的腔室 划分为若干区域, 分隔片 370的一侧连接第二弧形壁 364 , 另一侧连接 第三侧壁 362。 图中所示的若干区域的个数为三个, 分隔出的区域的个 数与分隔片 370 的个数相对应, 每个分隔区域上对应设置有一个开口 366。 在工作时, 第三侧壁 362、 第二弧形壁 364以及分隔片 370连同动 力轴 260—起旋转。
下面结合图 7来介绍离心压力泵的工作情况, 首先, 整个离心压力 泵 300内充满流体, 当动力轴 260在外力带动作用下开始旋转时 (如图 7中箭头 R所示的方向旋转), 离心压力泵 300内的流体开始向外输出, 同时, 第五流体入口通道 314开始吸进流体, 并充满旋转压力腔体 360 , 由于第二弧形壁 364上设置的开口 366较小, 旋转压力腔体 360内的流 体在其旋转的过程中同时充当了离心配重块的作用, 并储蓄有较大的离 心势能, 使得从开口 360进入集液通道 350的流体携带较大势能并从第 五流体出口 332进入第一压力缸 110或第二压力缸 120, 由此供给第一 压力缸 110和第二压力缸 120所需要的液压流体。图 6中的虚线 W示意 性地显示了离心压力泵工作时流体的大致流向。
该离心压力泵 300相对于现有技术的泵腔体而言, 新设计出了第二 腔体, 也即旋转压力腔体 360所形成的腔体。 第五流体入口 312的大小 大于第五流体出口 332的大小, 从而令大量流体留于腔内, 利用第二腔 体内的流体作为离心配重块, 增强流体的势能。 在本发明的实施例中, 该离心压力泵 300由增强型动力输出装置 200驱动。 该离心压力泵 300 利用第二腔体内的流体作为离心配重块, 可增强流体的势能。
气泵 400可采用市场上通用的压力气泵, 气泵 400上设置有入气口 (图未示)和出气口 410, 该出气口 410通过导管与第一气体出入口 114 和第二气体出入口 124连通, 用于提供压力气体给第一压力泵 110和第 二压力泵 120以推动第一活塞 111或第二活塞 121产生压力流体。当然, 也可采用其他类型的高压气泵。 在本发明的气压液压组合动力装置处于 初始工作状态时, 气泵 400需要由初始启动马达 401启动, 在气压液压 组合动力装置进处于稳定工作状态时, 气泵 400由动力输出单元 200提 供动力, 此时可适当减小初始启动马达的驱动力或直接撤除初始启动马 达 401。
在本发明的实施例中, 采用第一压力缸 110和第二压力缸 120交替 提供压力流体的方式驱动动力输出单元 200, 因此, 相应的导管上设有 对应的互锁开关控制器 (未示出) , 使得在某一时刻, 第一压力缸 110 由于气泵 400产生压力气体推动第一活塞 111的作用而产生压力流体来 驱动动力输出单元 200, 而第二压力缸 120由于离心压力泵 300产生压 力流体的作用而将压力流体提供到该压力缸内。 而在另一时刻, 第一压 力缸 110接收来自离心压力泵 300的压力流体, 第二压力缸 120则在气 泵 400的作用下产生压力流体来驱动动力输出单元 200。 市场上有许多 这种互锁开关控制器, 在此不再赘述。
下面结合以上各部件来介绍本发明的气压液压组合动力装置的工作 情况, 气压液压组合动力装置启动时首先经历初始工作状态, 后续再进 入稳定工作状态。 在初始工作状态下, 首先启动初始启动马达 401 , 气 泵 400由初始启动马达 401带动工作, 进而带动第一压力缸 110驱动增 强型动力输出装置 200。 在稳定工作状态下, 该气压液压组合动力装置 的工作情况可分为第一工作阶段和第二工作阶段。
在第一工作阶段, 第一压力缸 110内充满流体, 第二压力缸内没有 流体, 气泵 400开始工作产生高压气体, 气泵 400产生的高压气体经第 一气体出入口 114进入第一气体腔室 1111并推动第一活塞 111 , 此时, 与第一压力缸 110连通的导管上的开关控制器呈打开状态, 而与第二压 力缸 120连通的导管上的开关控制器呈关闭状态, 第一活塞 111在高压 气体的作用下将第一流体腔室 1112内的流体经第一流体出口 112压出, 进而驱动增强型动力输出装置 200, 增强型动力输出装置 200开始工作, 该增强型动力输出装置 200的旋转轴 260开始带动离心压力泵 300工作, 离心压力泵 300 产生高压流体经第二流体入口 123 进入第二流体腔室 1212,第二活塞 121在高压流体的作用下朝向第二气体出入口 124滑动, 将第二气体腔室 1211内的气体经第二气体出入口 124排出,当第一流体 腔室 1112内的流体完全流出时,第二流体腔室 1212内的流体完全充满, 第二气体腔室 1211内的气体完全排出,且第一活塞 111滑动至第一压力 缸 110的端部并靠近第一流体出口 112, 第二活塞 121滑动至第二压力 缸 120的端部并靠近第二气体出入口 124。
在第二工作阶段, 来自气泵 400的高压气体经第二气体出入口 124 进入第二气体腔室 1211 , 此时, 与第一压力缸 110连通的导管上的开关 控制器呈关闭状态, 而与第二压力缸 120连通的导管上的开关控制器呈 打开状态,第二活塞 121在高压气体的作用下将第二流体腔室 1212内的 流体经第二流体出口 122压出, 进而驱动增强型动力输出装置 200, 同 时, 来自离心压力泵 300的高压流体经第一流体入口 116进入第一流体 腔室 1112, 第一活塞 111在高压流体的作用下朝向第一气体出入口 114 滑动, 将第一气体腔室 1111内的气体经第一气体出入口 114排出, 当第 二流体腔室 1212内的流体完全流出时, 第一流体腔室 1112内的流体完 全充满, 第一气体腔室 1111内的气体完全排出, 且第二活塞 121滑动至 第二压力缸 120的端部并靠近第二流体出口 122, 第一活塞 111滑动至 第一压力缸 110的端部并靠近第一气体出入口 114。
在气泵 400不断供应高压气体的情况下, 第一工作阶段和第二工作 阶段交替进行。
在第一压力缸 110和第二压力缸 120交替工作期间, 增强型动力输 出装置 200能够获得持续稳定的流体动力, 从而带动离心压力泵 300和 气泵 400工作形成循环工作系统, 因而, 与增强型动力输出装置 200同 轴的动力接收装置 500也能够获得持续稳定的动力输入, 该动力接收装 置 500可为汽车发动机、 轮船发动机、 飞机发动机等, 因此, 本发明的 气压液压组合动力装置可在汽车驱动、 轮船驱动、 飞机驱动、 发电等领 域广泛应用。
需要指出的是, 在本发明一实施例中提到的 "第一" 、 "第二" 以 及 "第三" 等用语仅是根据需要采用的文字符号, 在实务中并不限于此, 并且该文字符号可以互换使用。
在上述实施例中, 仅对本发明进行了示范性描述, 但是本领域技术 人员在阅读本专利说明书后可以在不脱离本发明的精神和范围的情况下 对本发明进行各种修改。
