The invention relates to the technical field of water environment sampling, in particular to a flow velocity self-adaption-based floating island type water environment sampling device which comprises a floating island with a built-in driving device, and a sampling mechanism for sampling water and a guide mechanism for guiding the sampling mechanism are arranged in an inner cavity of the floating island. According to the floating island type water environment sampling device based on flow velocity self-adaption, a floating island driving and guide rope counterweight system ensures that a sampling cylinder is lowered along a vertical track, a guide rope penetrates through the center of the sampling cylinder, transverse displacement of the sampling cylinder is limited, lateral impact of water flow on the sampling cylinder is reduced, water layer disturbance is reduced, layered independent sampling and sealing guarantee are achieved, and the sampling efficiency is improved. The corresponding relation between the communication port and the water inlet tank is rotationally controlled, so that single-time lowering and multi-depth sampling are realized, and water samples are prevented from being mixed.

    本发明涉及一种基于流速自适应的浮岛式水环境采样装置,包括内置驱动设备的浮岛,所述浮岛的内腔分别设置有用于对水进行取样的取样机构和用于对取样机构进行导向的导向机构,本发明涉及水环境采样技术领域。该一种基于流速自适应的浮岛式水环境采样装置,浮岛驱动+导向绳配重系统:确保采样筒沿垂直轨迹下放,导向绳贯穿采样筒中心,限制其横向位移,降低水流对采样筒的侧向冲击,减少水层扰动,分层独立采样与密封保障,通过转动控制连通口与进水槽的对应关系,实现单次下放、多深度采样,避免水样混合。
