附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的列车新风进气融雪装置的轴测图；
图2为本发明实施例提供的列车新风进气融雪装置的俯视图；
图3为图2中B处的局部放大图。
其中，1为进风格栅；2为雨水分离器；201为拱形挡板；202为电加热管；203为V形挡板；204为第一导流板；205为第一U形挡板；206为排水孔；207为第二导流板；208为折边；209为第二U形挡板；3为压力波阀板。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-图3，图1为本发明实施例提供的列车新风进气融雪装置的轴测图，图2为本发明实施例提供的列车新风进气融雪装置的俯视图，图3为图2中B处的局部放大图。
本发明实施例提供了一种列车新风进气融雪装置，该列车新风进气融雪装置包括进风格栅1、雨水分离器2以及加热装置。
其中，雨水分离器2沿进风方向设置于进风格栅1之后，用于分离进风中夹带的雪水，雨水分离器2具有迷宫型进风通道以及排水孔206，迷宫型进风通道对进风进行阻挡、碰撞，使其变向、变速，从而将其夹带的雪水分离出来从排水孔206中排出，排水孔206通常形成于雨水分离器2的底部，雨水分离器2内在靠近进风格栅1的一侧设置有加热装置。
综上所述，与现有技术相比，本发明实施例提供的列车新风进气融雪装置当其进风格栅1进风口处形成积雪时，可开启加热装置融化积雪，同时雨水分离器2的迷宫型进风通道能够将由于融雪而夹带在进风中的水分离出来并从排水孔206排出，由此可见，上述列车新风进气融雪装置在雨水分离器2上集成了加热装置，占用空间小，无需对现有结构进行改变，能够将进风格栅1进风口处的积雪融化，消除进风阻力，保证空调进风量，同时避免雪水进入空调系统，保证在暴雪天气和低温工况下的列车空调系统性能。
作为优选地，上述雨水分离器2包括相对于进风格栅1由近及远依次设置且相互错落的一排拱形挡板201以及至少一排U形挡板，拱形挡板201向进风格栅1方向拱起，即拱形挡板201的拱面影响进风，对进风进行分流引导，进风从两个拱形挡板201的间隙进入雨水分离器2内部，由于U形挡板的开口朝向进风格栅1方向，从两个拱形挡板201的间隙进入的进风经U形挡板的开口中部进入U形挡板的内部，在U形挡板的内部经U形挡板的内壁导流变向后从U形挡板的开口边缘流出，并经拱形挡板201与U形挡板的间隙继续向后移动，该种结构的雨水分离器2结构简单，仅需要几排错落布置的挡板即可实现迷宫型进风通道，便于批量制造。
更进一步，雨水分离器2还包括壳体，壳体上形成由朝向进风格栅1的开口，U形挡板以及拱形挡板201均设置于壳体内，且U形挡板以及拱形挡板201的两端分别于壳体的顶板以及底板连接。
当然上述结构仅仅是本发明实施例提供的一种优选实施方案，实际并不局限于此，本领域技术人员可根据实际需要对其进行适当调整，在此不做限定。
进一步地，由上述进风流动过程可知，进风与雨水的分离主要发生在U 形挡板内，因此，为便于将雪水排出，在本发明一种实施例中，每个U形挡板下方均设置排水孔206，即在雨水分离器2壳体的底板上的对应位置开设有排水孔206，这样，当进风与U形挡板的内壁发生碰撞后，U形挡板的内壁上会形成由雪水形成的水滴，水滴汇集向下流入排水孔206排出。
在其他实施例中，也可以在所有的U形挡板下方设置集水盘，并在集水盘的最低点设置排水孔206。
作为优选地，在本发明实施例中，加热装置包括电加热管202，电加热管202一一对应地设置于拱形挡板201远离进风格栅1的一侧。
需要说明的是，加热装置也可以为加热膜、加热丝等，设置于拱形挡板201的表面或内部，当然，除拱形挡板201外，U形挡板上也可以设置加热装置。
为避免电加热管202与雨水、雪水接触，在本发明实施例中，雨水分离器2还包括V形挡板203，该V形挡板203的开口朝向拱形挡板201，且V形挡板203与拱形挡板201连接围成容纳电加热管202的容腔，这样V形挡板203与拱形挡板201以及雨水分离器2的顶板以及底板能够围成一封闭的容腔，将电加热管202与外界隔离。
进一步优化上述技术方案，为提高雨水分离器2的分离效果，在本发明实施例中，雨水分离器2包括一排第一U形挡板205以及一排第二U形挡板209，进风需要经过两次滤水后才能够进入空调系统，同时经过U形挡板后的进风的流向发生改变，为避免同一排各个U形挡板流出的进风相互干扰，V形挡板203的尖端形成有延伸至相邻两个第一U形挡板205之间的第一导流板204，第一U形挡板205上形成有延伸至相邻两个第二U形挡板209之间的第二导流板207，这样进风从第一U形挡板205流出后，在第一导流板204的作用下流向第二U形挡板209，从第二U形挡板209流出后在第二导流板207的作用下流入空调系统。
可以理解的是，雨水分离器2的构成并不局限于上述的拱形挡板201、U形挡板、V形挡板203等等，还可以采用其他的规则或不规则结构以形成迷宫型通道。
为进一步提高U形挡板对雨水的分离效果，在本发明实施例中，U形挡 板的开口两侧形成有向U形挡板内延伸的折边208，两个折边208沿延伸方向间距逐渐缩小，利用U形挡板开口处的两个折边208能够在进风流出U形挡板时再次迫使其变向，从而使进风在U形挡板内形成两次变向，更好地实现分离效果。
作为优选地，列车新风进气融雪装置还包括温度传感器以及控制器，温度传感器设置于进风格栅1的进风口处，用于测量进风格栅1的进风口处的温度，温度传感器与控制器信号连接，控制器用于在进风格栅1的进风口处的温度低于预设值时控制加热装置启动以及在进风格栅1的进风口处的温度高于预设值时控制加热装置关闭，以实现对融雪装置的自动控制，便于使用。
进一步地，列车新风进气融雪装置还包括与控制器信号连接的温度传感器，温度传感器用于监测加热装置的温度，当加热装置发生过热，控制器关闭加热装置避免其因过热而失效。
进一步优化上述技术方案，在本发明实施例中，列车新风进气融雪装置还包括沿进风方向设置于雨水分离器2后的压力波阀板3。
基于上述实施例中提供的，本发明还提供了一种轨道列车，该轨道列车包括如上任一项所述的列车新风进气融雪装置。由于该轨道列车采用了上述实施例中的列车新风进气融雪装置，所以轨道列车的有益效果请参考上述实施例。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
