Abstract

The invention provides a multi-point sampling device for the offshore water quality and sediment. The multi-point sampling device comprises a support assembly. A water sampling assembly and a sedimentsampling assembly are arranged on the support assembly circumferentially. The support assembly includes an upper support plate, a lower support plate and a main support frame that are integrated intoone; the upper support plate is horizontally disposed above the lower support plate; and the main support frame is vertically fixed between the upper support plate and the lower support plate. The water sampling assembly includes a plurality of sampling tubes; the tops of the sampling tubes folded outwardly to form a horizontally arranged sampling inlet that is arranged outwardly; and a plug assembly is arranged at the sampling inlet. In addition, the sediment sampling assembly includes a sampling assembly shell based on a positive quadrangular prism structure; and a sampling cavity with an open bottom is formed in the sampling assembly shell. Therefore, water different depths as well as sediments on the seabed can be sampled; and device having advantages of diversified functions and great convenience in operation is capable of carrying out sampling effectively and rapidly.

Description

technical field [0001] The invention relates to a sampling device, in particular to a multi-point sampling device for offshore water quality and sediment. Background technique [0002] Due to the increasingly intensified competition for global marine resources, the composition analysis of seabed sediments has gradually become the top priority of marine strategies of various countries, and the extraction of underwater sediments has naturally become an increasingly critical link. Abroad already has a batch sampling plan such as the "ARGO plan", while my country has just started, and is still in the initial stage of manual throwing and artificial take-up fixed-point sampling. Most of the large-scale seabed sampling in our country is carried out by large ships sailing to the sampling point, throwing the sampler and staying there until the sampling is finished, then take up the line and return. Such sampling methods are expensive and time-consuming. [0003] Moreover, the exist...
