The invention discloses an unmanned ship-borne seawater sampling method. The method comprises the following steps: S1, fixing sampling bottles on an unmanned ship; and S2, the unmanned ship is started to reach the first water taking point position. And S3, the driving assembly drives the winding drum to rotate to lower the water taking pipe, the winding drum stops rotating after reaching the set depth, and the lower end opening of the water taking pipe is kept at the set depth. And S4, the adjustable throttling valve is opened, the flushing pump starts to work, and seawater enters the water taking pipe to flush the water inlet main pipe. And S5, opening a two-way electromagnetic valve between the first sampling bottle and the water inlet main pipe as well as between the first sampling bottle and the water outlet main pipe, and opening a sampling pump to sample seawater. And S6, the steps S2 to S5 are repeated, seawater sampling of other water taking points is completed in sequence, and the unmanned ship returns. The depth of a seawater sampling point is accurate, water flow interference is avoided, a pumping mode is replaced by a drawing mode, seawater does not need to pass through a pump before entering a sample bottle, the influence of the pump on a water sample is eliminated, the requirement for load miniaturization of the unmanned ship is met, and the water quality detection accuracy is improved.

    本发明公开了一种无人船载海水取样方法,包括如下步骤:S1、将各取样瓶固定于无人艇上。S2、无人艇启动,到达首位次取水点位。S3、驱动组件驱动卷筒转动将取水管下放,到达设定深度后卷筒停止转动,取水管下端口保持在设定深度。S4、可调式节流阀开启,冲洗泵开始工作,海水进入取水管对进水主管进行冲洗。S5、开启首位次取样瓶与进水主管和出水主管之间的二通电磁阀,开启取样泵,进行海水取样。S6、重复步骤S2至S5,依次完成其余位次取水点位的海水取样,无人艇返回。本发明海水取样点深度精确,不受水流干扰,以汲取方式替代泵送方式,海水进入样品瓶前不需经过泵,消除泵对水样影响,满足无人艇载荷小型化要求,提高水质检测准确性。
