Bio-adhesion preventing in-situ seawater sample and particulate automatically collecting device and method

Abstract

The invention discloses a bio-adhesion preventing in-situ seawater sample and particulate automatically collecting device and method. The bio-adhesion preventing in-situ seawater sample and particulate automatically collecting device comprises a control system, a piston system, a port system and a collecting and filtering system, wherein the collecting and filtering system comprises N water samplecollectors and N particulate collectors connected with the inlets of the water sample collectors, the inside of every particulate collector is provided with a filter mesh, and the upper layer and thelower layer of every filter mesh are provided with copper mesh cushions; the control system executes and achieves fully-automatic rotation of ports as well as movement of a piston, and collection ofa fixed quantity of water samples and particulates at equal time intervals. The bio-adhesion preventing in-situ seawater sample and particulate automatically collecting device can adopt different materials or sealing techniques such as PVC (polyvinyl chloride or titanium alloy) and meet the requirements on offshore or remote and deep full-depth collection of water samples and particulates, and meanwhile, is applicable to in-situ online application for a long time.

Description

technical field [0001] The invention belongs to the field of seawater chemical in-situ on-line monitoring, and provides an easy-to-operate device for collecting water samples and particulate matter in-situ automatically and at equal time intervals in the ocean for a long time, and at the same time performs pre-pollution-free filtering treatment, and specifically relates to a source for preventing biological adhesion A device and method for automatically collecting seawater samples and particulate matters. Background technique [0002] The collection of seawater samples and particulate matter is an important link in ocean monitoring and seawater research. For medium and long-term collection work, the automatic operation function of the device used is particularly important. Seawater samples and particulate matter are collected and stored at the same time. Anti-biological adhesion in seawater environment is also one of the difficult problems that the sampling system must overc...

AI Technical Summary

Problems solved by technology

In general, two sets of devices are used for the collection and storage of seawater samples and particulate matter in the medium and long term. At present, the commercialized in-situ filtration devices at home and abroad are expensive and prone to biofouling (such as Pall TM 、Millipore TM and other brands), and the automation link in operation is relatively weak; most of the automatic collection devices are for the collection of phytoplankton and suspended particles (such as McLane TM and other brands), lack of collection and preservation of seawater samples in the same period, and lack of direct data support in the process of studying the exchange of nutrients in the ecosystem
