The invention discloses a sample collection device for marine pollutants in the field of sample collection, and the sample collection device comprises a suspension assembly and a collection box, and the collection box is divided into a plurality of sample bins; each sample bin is communicated with a sample injection pipeline, and a connecting plate, a through groove, a bracket, a spring and a baffle plate are arranged on each sample injection pipeline. When the device is used, the collecting box is put into the sea, and in the sinking process of the collecting box, the pressure of seawater on the periphery can be gradually increased. When the spring deforms, the baffle is separated from the connecting plate, and at the moment, seawater enters the sample bin through the through groove and the sample feeding pipeline. By using the springs with different elastic coefficients, the sampling box opens the sample introduction pipeline at different ocean depth positions, so that the ocean pollutant samples with different depths automatically enter the sample bin, the ocean pollutant samples with different depths in the ocean are collected, and the problem that the ocean pollutant samples with different depths cannot be collected is solved.

    本发明公开了样本采集领域的一种用于海洋污染物的样本采集装置,包括悬浮组件和采集箱,采集箱分为若干样本仓;样本仓均连通有进样管道,进样管道上设有连接板、通槽、支架、弹簧和挡板。使用该装置时,将采集箱投放于海中,采集箱在下沉过程中,四周所受到海水的压力会逐渐变大。此时挡板及所连接的弹簧受到的压力逐渐增大,当弹簧簧发生变形时,挡板脱离连接板,此时海水将经过通槽及进样管道进入样本仓中。通过使用不同弹性系数弹簧,采集箱在不同海洋深度的位置开启进样管道,使不同深度的海洋污染物样本自动进入样本仓内,采集海洋中不同深度的海洋污染物样本,解决了不能采集不同深度的海洋污染物样本的问题。
