Description

一种气流收集装置、风力发动机及机动车 技术领域
本发明涉及一种气流收集装置及发动机，特别适合于各种机动车。
 背景技术
用燃料作为能源的发动机需要消耗大量的燃料，且又排放大量的废气、热气，污染环境。为了节省燃料能源，保护地球环境，人类更渴望一种无需燃料消耗，杜绝废气、热气排放、无污染的发动。
为了能更直接地利用风能，特别是为了能够将动力机械在行驶过程中所遇到的风阻气流直接加以利用，本发明的申请人提出了专利号为200580044218.6、发明名称为“风气发动机即采用风力气压取代燃料能源的发动机”的中国专利。该发明公开了一种风气发动机及机动车，包括至少一个叶轮室、装设在叶轮室内的叶轮和用于将压缩气体喷入叶轮室的喷气系统，该发明的主要特点在于在叶轮室上设置了设置喷气系统和用于接收外部风阻气流的进风口。使用时，该发明的风气发动机安装在能够行驶的动力机械上（特别是机动车），通过设置喷气系统，采用压缩气体作为主动力，无燃料消耗，无废气、热气排放、无污染。通过设置接收外部风阻气流的进风口，可以将动力机械在行驶过程中所遇到的风阻气流直接加以利用，变阻力为动力。
虽然，上述发明首创性地提出了直接利用风阻气流作为辅助动力以及同时采用压缩气体作为主动力的风气发动机及采用该风气发动机的机动车，不但不需要将风阻气流转换成电能，因而没有复杂的机电能量转换系统和电路控制系统，大大简化了动力机械、特别是机动车的结构，而且为节约能源和寻找环保型的燃油代用品提供了一个新的途径。但是，为了能够更好地利用风阻气流和压缩气体，使主动力和辅助动力之间产生最佳的配合，提高主动力的使用效率，发明人又提出了一种申请号为200780030483.8、发明名称为组合式风气发动机及机动车的发明专利申请。该发明的主要特点是分别设置独立结构的压缩气体（压缩气体）发动机和风阻（风力）发动机，可根据压缩气体的流速高、相对集中，而风阻气流的流速低、相对分散的特点，分别有针对性地对叶轮进行优化设计（如：风阻发动机的叶轮叶面设计得要小，风阻发动机的叶轮叶面设计得要大），以提高能量转换效率。采用该组合式风气发动机的机动车既采用压缩气体作为主动力，又直接采用动力机械在行驶过程中所遇到的风阻气流作为辅助动力，还可以使压缩气体和风阻气流能够更好地配合使用。
但是，上述新型的以压缩空气作为主动力、以接收利用风阻气流作为辅助动力的新能源汽车，仍还有大量的技术工作要做。
 技术问题
本发明要解决的主要技术问题是，进一步优化气流收集的装置，使收集的气流更集中，使风力发动机更有效地利用收集的气流产生更强的动力。
 技术解决方案
解决上述技术问题的技术方案：
一种气流收集装置，包括外口大、内口小的气流收集通道，在所述气流收集通道内设置有导流体。
一种风力发动机，包括气流收集装置、至少一个叶轮室、通过动力输出轴装设于所述叶轮室内的至少一个叶轮，所述气流收集装置包括外口大、内口小的气流收集通道，在所述气流收集通道内设置有导流体，在所述叶轮径向的外周面上固定有叶片，所述导流体与所述气流收集通道之间形成的气流通道与所述叶片相通，使得气流通道内收集的气流直接作用于所述叶片上。
进一步地，所述导流体基本固定在靠近内口处的气流收集通道的中轴线上，所述导流体基本呈从内口沿外口方向延伸的凸出部。
进一步地，所述导流体基本呈从内口沿外口方向延伸的锥形体，所述气流收集通道与所述导流体之间形成环形气流通道，所述环形气流通道与所述叶轮外周面上对应呈环形设置的叶片相通，使得气流通道内收集的环形气流直接作用于所述叶轮外周面上环形设置的叶片上，从而驱动叶轮旋转。
进一步地，所述叶轮的侧面固定有用于将气流引导至周围叶片上的导流罩。
进一步地，所述至少一个叶轮室为至少两级叶轮室，各级叶轮共用动力输出轴装设于各级叶轮室内，在所述各级叶轮径向的外周面上固定有叶片，从前一级叶轮室流出的气流经气流通道作用于后一级叶轮室内的叶片上。
一种风能收集装置，包括前述风力发动机、气体压缩装置和储气罐，所述风力发动机输出的动力传动气体压缩装置，所述气体压缩装置产生的压缩气体输入储气罐储存。
一种装有前述风力发动机的机动车，风力发动机通过动力输出轴向机动车的传动轴输出动力。
进一步地，还包括至少两级压缩气体发动机，每一级压缩气体发动机包括至少一个叶轮室、通过转轴装设于所述叶轮室内的至少一个叶轮，每一级叶轮室上开设有至少一个进气口和至少一个排气口，其中前一级叶轮室上的排气口与后一级叶轮室上的进气口相通，每一级叶轮通过转轴向机动车的传动轴输出动力。
 有益效果
采用上述技术方案，本发明有益的技术效果在于：
通过在气流收集通道内设置导流体，能够根据需要，灵活地改变导流体的大小和形状，使收集的气流更集中、更具有方向性。特别是，当应用于发动机时，可以将气流（风阻）直接导流到叶轮端部的叶片，产生更大的扭矩输出。另外，将气流（风阻）直接导流到叶轮端部的叶片上，避免了当气流流经叶轮叶片中心部位时因气流遇阻所产生的气流紊乱现象，提高发动机对风能的利用率。

压缩气体发动机200包括左侧压缩气体发动机、右侧压缩气体发动机和传动轴19，左右两侧压缩气体发动机呈左右对称结构。以左侧压缩气体发动机为例，左侧压缩气体发动机包括第一级压缩气体发动机210和第二级压缩气体发动机220，第一级压缩气体发动机210与第二级压缩气体发动机220共轴装设在同一转轴203上，左右两侧压缩气体发动机产生的动力经转轴203传动机动车的传动轴300。第一级压缩气体发动机210与第二级压缩气体发动机220的结构相同。
以第一级压缩气体发动机210为例，第一级压缩气体发动机210包括叶轮室215、通过转轴203装设于叶轮室215内的叶轮220，叶轮219上具有多个等分设置的叶齿216，叶轮室215上开设有多个进气口211和排气口212，进气口211上装设有喷嘴217，第一级叶轮室215上的排气口212与第二级叶轮室225上的进气口221相通。
如图4和图5所示，为了提高动力性能，在叶轮室215的内表面上开设有沿转动周面设置的、与进气口211相通的喷气导入槽213，接近进气口211时的喷气导入槽213深而宽，远离进气口211时的喷气导入槽213浅而窄（图5），喷气导入槽213的长度大于两个相邻叶齿216之间的距离L（标号218），使得从喷气导入槽213导出的压缩气体一是能够同时作用于二个或两个以上的叶齿216上，二是能够按照预设的导出路径作用在希望的叶齿部位，以产生更强的推力。另外，为了加大喷气力度，本实施例同一喷气导入槽213上装设两个喷嘴217。
在叶轮室215的内表面上开设有与转轴轴线平行的排气槽214，排气槽214与排气口212相通。为了更好的排气，排气槽214的宽度与叶轮220的宽度基本相一致。
第一级压缩气体发动机210的叶轮直径小，第二级压缩气体发动机220的叶轮直径大。为了使气体顺畅，第一级排气口212的直径是第一级进气口211的2—10倍，第二级排气口222的直径是第二级进气口221的2-10倍，可根据需要灵活设置。
为了防止漏气，避免刚喷入的气体直接从排气槽214排出，喷气导入槽213末端与最近的排气槽214之间的距离应大于两个相邻叶齿之间的距离L。
工作时，首先通过机动车的喷气系统（未画）经喷嘴217向第一级压缩气体发动机210内喷入压缩气体，经第一级压缩气体发动机210减压、稳压后进入第二级压缩气体发动机220。第一级压缩气体发动机210既起减压、稳压作用，又将释放压缩气体过程中产生的能量充分利用起来，第一级压缩气体发动机210同时提供部分动力。第二级压缩气体发动机220提供主动力。当机动车达到一定速度时，风阻气流经气流收集装置进入风阻发动机100产生辅助动力。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
