The invention belongs to the field of environment monitoring equipment, and particularly relates to a water body micro-plastic collecting device which comprises a collecting unit. The filtering device comprises a filter screen and a collecting pipe connected with the tail part of the filter screen; the screen head fixing piece is used for connecting the outlet of the sample injection box and the head of the filter screen; the net opening opening and closing control assembly is arranged on the sample injection box, is connected with the net head fixing piece and is used for controlling the net opening of the filtering device to be closed; and the trawl control component is in communication connection with the network port opening and closing control assembly and controls the operation of the network port opening and closing control assembly after receiving the instruction. The invention further provides a water body micro-plastic three-dimensional collection system which comprises a plurality of sets of collection devices which are sequentially connected in the depth direction of a water body. By controlling the opening and closing of the screen opening of the filter, not collecting a water sample before the screen opening reaches a specified depth, and directly closing the screen opening to stop filtering when sampling is finished, the filtering time node can be accurately controlled, the loss of a sample in the filter in the process of collecting and releasing equipment is avoided, and the data reliability and accuracy are ensured.

    本申请属环境监测设备领域,具体涉及一种水体微塑料采集装置,包括采集单元,采集单元包括:进样箱;过滤装置,包括滤网和与滤网尾部连接的收集管;网头固定件,用于连接进样箱的出口和滤网的头部;网口开闭控制组件,设置于进样箱上,与网头固定件连接,用于控制过滤装置的网口关闭;拖网控制部件,与网口开闭控制组件通信连接,接受指令后,控制网口开闭控制组件的运行。还提供一种水体微塑料三维采集系统,沿水体深度方向包括依次连接的多组上述采集装置。通过控制过滤器网口开闭,在网口到达指定深度前不采集水样,采样结束时直接关闭网口停止过滤,可精确控制过滤时间节点,避免在收放设备过程中过滤器内样品损失,保证数据可靠性和准确性。
