本发明涉及直升机甲板的排水系统及其排水方法。 直升机甲板的排水系统包括：以规律的间隔安装在直升机甲板的地板上的多个排水孔; 一个储存一个液体的腔室，它移动穿过排泄物; 用于检测存储在所述室中的流体的污染的检测装置; 用于通过检测装置储存腔室的污染流体的罐; 以及控制单元，用于根据由检测装置检测到的流体的污染将流体排放到水箱或海面。 腔室临时存储从直升机甲板排出的液体，并且储存罐临时储存受污染的流体，以根据流体是否被污染来选择性地排出流体。 被污染的液体和非污染的液体可以单独排放，以防止环境污染。 流体的输送可以通过阀门自由调节。 安装简单，结构简单。

Relates to a drainage system and drain method of the heli-deck, a plurality of hibiscus buffer, a chamber in which the moving fluid through the hibiscus buffer storage provided at regular intervals on the floor of the heli-deck, sensing for detecting contamination of a fluid stored in the chamber It means, by the fluid, depending on whether contamination of the fluid sensed by that the contaminated fluid reservoir, said sensing means providing a control unit for controlling such that the discharge to the tank or sea level drained from Heli deck of the chamber by said sensing means the fluids temporary storage tank for storing the contaminated fluid and the chamber date that is provided can be selectively discharged in accordance with the pollution if the fluid to remove the contaminated fluid and uncontaminated fluid pollution can be discharged installation can be prevented, it is possible to freely control the feeding of fluid by a valve, made in a simple structure The effect is obtained that easy.
