Abstract

The invention provides an in-situ acoustic measurement component of seafloor sediment. The component comprises an in-situ measurement sleeve, connecting arm plates and probing rod installation pipes,wherein the in-situ measurement sleeve is respectively connected with a sampling pipe and a tool bit; the connecting arm plates are arranged on the outer surface of the in-situ measurement sleeve; theprobing rod installation pipes are welded on the outer surfaces of the connecting arm plates, and the bottom ends are provided with threads, which are used for connecting with acoustic probing rods;the number of the connecting arm plates, the probing rod installation pipes and the acoustic probing rods are all in one-to-one correspondence. By additionally arranging the in-situ measurement sleeveon a current sampling pipe and arranging the connecting arm plates and the probing rod installation pipes, which are used for in-situ acoustic measurement, on the in-situ measurement sleeve, the fixation and installation of an in-situ acoustic transducer are realized, so that the seafloor sediment sampling and in-situ acoustic measurement are realized in a two-in-one mode, two sets of different equipment do not require to be used, the whole efficiency of sediment measuring and sampling is improved, and the equipment is more convenient to carry. In addition, the in-situ measurement sleeve further strengthens the connecting stability of the tool bit and the sampling pipe.

Description

Technical field [0001] This application relates to the technical field of acoustic detection, and in particular to an in-situ acoustic measurement component of seabed sediments. Background technique [0002] In order to obtain the in-situ acoustic characteristics of seabed sediments, a variety of acoustic measurement instruments have been developed on the basis of in-situ measurement technology, such as in-situ sediment acoustic measurement systems, acoustic spears, etc. These devices can independently perform in-situ acoustic measurements . However, since in-situ measurement equipment cannot obtain samples of seabed sediments, it is not possible to describe the types of sediments and physical characteristics parameters. [0003] Currently, the gravity sampler is one of the basic equipment for seabed sediment sampling. It has the characteristics of simple structure and convenient operation, but it can only perform sediment sampling operations. If in-situ measurement and simultane...
