摘要： A drainage device for placement on a housing includes an external plug component and a liquid expandable component. The external plug component has a first cap section and a second attachment section. The first cap section is positionable over an exterior side of a housing wall. The first attachment section is adapted to attach the drainage device to an opening in the housing wall. The liquid expandable component contacts the external plug component and is adapted to contact a structure within the housing when the drainage device is placed on the housing. Characteristically, the liquid expandable component has a higher volume when contacted with liquid than when dry. The liquid expandable component pushes the internal plug component away from the structure within the housing when the liquid expandable component transitions from a non-liquid-containing state to a liquid containing state thereby providing a path for liquid to escape.
摘要翻译：用于放置在壳体上的排水装置包括外部塞子部件和液体可膨胀部件。外部插头部件具有第一盖部分和第二连接部分。第一盖部分可定位在壳体壁的外侧上。第一附接部分适于将排水装置附接到壳体壁中的开口。液体可膨胀组件接触外部插头部件，并且当排水装置放置在壳体上时适于接触壳体内的结构。特别地，当与液体接触时，液体可膨胀组分具有比干燥时更高的体积。当液体可膨胀部件从非液体状态转移到液体容纳状态时，液体可膨胀部件将内部塞子部件推离壳体内的结构，从而提供液体逸出的路径。
