图4是本实用新型一种环保型船舶通风装置的平稳板的结构示意图。
具体实施方式
下面结合附图说明，对本实用新型作进一步详细说明。
如图1-4所示，一种环保型船舶通风装置，包括船舱1、以及分别与船舱1连通的进风管道2和排风管道3，排风管道3的出风口处设有通风头4。
其中，进风管道1内设有多个相互平行设置的半导体制冷片21，半导体制冷片21可以通过支架固定安装于进风管道1的内壁，多个半导体制冷片21沿进风管道2的径向均匀分布，每个半导体制冷片21均与进风管道2的轴线呈45°夹角，由此能够使半导体制冷片与空气的充分接触，提高干燥效果，进风管道2内设有进风机22，进风机22可以通过支架固定安装于进风管道2的内壁，进风机22能够将船舱外的空气吸进船舱内。
其中，排风管道3内设有排风机31，排风机31可以将船舱内的空气排到船舱外，排风管道3包括U形管32，在本实施例中，U形管32的一端可以通过一根直管连通于船舱1，另一端也可以通过另一根直管连通通风头4。U形管32内装有洗涤液，U形管32靠近排风管道3出风口的一端内设有平稳板33，平稳板33位于洗涤液的液面上，平稳板33四周边缘与U形管32内壁之间具有空隙34，平稳板33的四周可以通过连接杆与U形管32的内壁固定连接，平稳板33均布有多个孔道35，每个孔道35均包括位于同一平面且依次连接的第一通道36、第二通道37和第三通道38，第一通道36与第二通道37之间呈钝角设置，第二通道37与第三通道38之间呈钝角设置，第一通道36与第三通道38平行，在本实施例中钝角为120°角，由此能够对洗涤液液面的晃动起到缓冲作用。由此，洗涤液的液面与平稳板33保持一致，这样当排风机31开始运转时，气体能从孔道35中被吸出，U形管32中的的洗涤液液面不会大范围晃动，能保持工作的稳定性。平稳板33与U形管内周壁的空隙34，可以使得洗涤液可以在空隙34的范围内进行晃动，能保证排风机吸气的正常运转，且也能保证洗涤液的稳定。
其中，通风头4包括一端开口的筒体41，筒体41倒扣于排风管道3的出风口处，筒体41底部与排风管道3出风口之间通过支撑部42支撑连接，筒体41的开口处与排风管道3外壁之间环形均布有多个S形金属片43，每个S形金属片43均沿筒体41轴线方向设置，S形金属片一侧边缘与排风管道3的外壁焊接，另一侧可以与筒体41开口处的内壁嵌合连接。由此，能够有效防止雨水和海水进入到排风管道3内，还能使排气时更加稳定，降低噪音。
此外，进风管道2内沿轴向方向还设有第一干燥板23和第二干燥板24，第一干燥板23和第二干燥板24的四周边缘可以固定连接于进风管道 2的内壁，第一干燥板23和第二干燥板24表面均开设有多排蜂窝孔25，第一干燥板23的第奇数排蜂窝孔25内填充有干燥剂26；第二干燥板24的第偶数排蜂窝孔25内填充有干燥剂26，第一干燥板23和第二干燥板24均沿进风管道2的径向设置。由此，通过干燥剂能够进一步对空气进行干燥，且通过设置两个干燥板，每个干燥板上设置的干燥剂也不对称，能够使空气与干燥剂充分接触，提高干燥效果。
此外，进风管道2位于半导体制冷片21正下方处开设有排水槽27。由此，空气中的水汽在液化后能够通过排水槽27排出。
此外，U形管32靠近船舱1的一端设有金属过滤网39，金属过滤网39的四周边缘可以焊接连接于U形管32的内壁。由此，可以对空气进行初步净化，也能防止较大的杂物进入U形管内。
此外，支撑部42包括底座44和设置于底座44的气缸45，底座44设置于排风管道3内靠近出风口处，气缸45输出端固定连接于筒体41底部，底座44包括两个交叉设置的支撑杆，支撑杆的端部固定连接于排风管道3的内壁。由此，能够通过调节筒体底部与排风管道出风口处之间的距离来调节排风量的大小。
此外，排风管道3位于出风口处的端部边缘包裹有橡胶圈46。由此，当需要将排风口关闭使，橡胶圈能够提高筒体底部与排风管道出风口处之间的密封性。
综上，本实用新型通过在进风管道加装半导体制冷片，利用水汽遇冷液化的原理，对空气进行干燥，使得吸进船舱内的空气比较干燥，提高船员生活质量，防止对船舶设备造成腐蚀；还通过在排风管道内加装洗涤液的U型管，通过洗涤液将舱室内的空气进化后再排出去，有利于环境保护；在出风口处设置筒体形状的罩体，在罩体开口处设置S形金属片，能够有效防止雨水和海水进入到排风管内，还能使排气时更加稳定，降低噪音。
以上所述仅是本实用新型的一种实施方式，应当指出，对于本领域普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出若干相似的变形和改进，这些也应视为本实用新型的保护范围之内。
