The invention relates to the technical field of water sample collection, and particularly discloses a multi-point water quality sampling instrument and a sampling method thereof. The multi-point water quality sampling instrument comprises a power mechanism, a sampling mechanism and a storage mechanism, the power mechanism provides power for the sampling mechanism, and the storage mechanism stores a water sample taken by the sampling mechanism; wherein the sampling mechanism comprises a transmission part, a sampling piston, an external water inlet and a sampling pipe, the transmission part is connected with the power mechanism and the sampling piston, the sampling piston is arranged in the sampling pipe, the bottom of the sampling pipe is in a non-closed state, the transmission part drives the sampling piston to move in the sampling pipe, and the top of the sampling pipe is communicated with the external water inlet; the storage mechanism comprises a plurality of water storage bottles, and the sampling water outlet is connected with water inlets of the plurality of water storage bottles. The sampling piston is driven by the transmission part to move, an external water sample is quickly sucked into the sampling pipe under the action of pressure difference, one-time water drainage and multiple sampling can be realized, and the heavy buoyancy of the whole device before and after water taking is ensured to be unchanged.

    本发明涉及水样采集技术领域,具体公开了一种多点位水质采样仪及其取样方法。该多点位水质采样仪包括动力机构、取样机构以及存储机构,动力机构为取样机构提供动力,存储机构存储取样机构取入的水样;其中取样机构包括传动件、取样活塞、外部进水口以及取样管,传动件连接动力机构与取样活塞,取样活塞设置于取样管内,取样管的底部为非封闭状态,传动件带动取样活塞在取样管内进行运动,且取样管的顶部与所述外部进水口连通;存储机构则包括多个储水瓶,取样出水口连接多个储水瓶的进水口。本申请通过传动件带动取样活塞运动,在压差的作用下使外部水样被快速吸入取样管内,且可实现一次下水、多次取样,保证取水前后整个装置的重浮力不变。
