Abstract

The invention relates to multistage marine water quality stratified sampling equipment and a sampling method thereof. The multistage marine water quality stratified sampling equipment comprises a floating plate, a pay-off device and a sampling device, wherein the floating plate is of a rectangular structure, the pay-off device is installed at the upper end of the floating plate, the sampling device is arranged below the floating plate, and the sampling device is connected with the pay-off device through a steel wire rope. The problems as follows are solved: when the existing equipment is usedfor sampling the ocean water quality, the sampling effect is poor and the sampling is inaccurate, and stratified sampling cannot be effectively carried out on seawater with different depths, which isnot conducive to the study of ocean water quality; and the existing equipment cannot effectively seal the sampled seawater when sampling the ocean water quality, so that the sampled seawater is easilymixed with seawater in areas with different depths, the sample is inaccurate, and the accuracy of a water sample analysis result is influenced.

Description

technical field

[0001] The invention relates to the field of seawater sampling, in particular to a multi-stage marine water quality layered sampling device and a sampling method thereof. Background technique

[0002] With the implementation of the national ocean development strategy, people are turning more and more attention to the ocean, which is rich in mineral resources, marine biological resources and energy. Ocean research is one of the research priorities of countries all over the world. In order to grasp first-hand ocean data, researchers need to sample and analyze seawater at different depths.

[0003] At present, the existing sea water quality usually has the following defects when sampling the sea water quality: 1. The existing equipment has poor sampling effect and inaccurate sampling when sampling the sea water quality, and cannot effectively analyze sea water at different depths; Layer sampling is not conducive to the research of marine water quality; 2. When ...
