Abstract

The invention discloses a handheld bottom sediment columnar sample profile acoustic full-automatic measurement device and method, and belongs to the field of marine geological detection. The device comprises a reflector used for reflecting laser; a laser ranging probe used for emitting ranging laser; an acoustic emission acquisition control unit; an acoustic transducer; a central processor; a lithium battery; and a display. According to the device disclosed by the invention, the sound velocity and sound attenuation of the seabed sediments in the transverse direction and the longitudinal direction of the box-type sampler and in the longitudinal direction of the columnar sampler can be quickly, conveniently and accurately obtained on a deck after sampling on the sea.

Description

technical field [0001] The invention relates to the technical field of marine geological exploration, in particular to a hand-held acoustic fully automatic measuring device and method for a seabed sediment sample profile. Background technique [0002] Acoustic parameters of seabed sediments have very important application value for marine engineering geological exploration, analysis of ocean acoustic field, development of seabed oil and gas and other mineral resources, monitoring of seabed geological disasters, etc. [0003] At present, there are two main methods for direct measurement of acoustic parameters of seabed sediments: seabed in-situ measurement and laboratory measurement. In-situ measurement on the seabed can reduce temperature, pressure, and sediment disturbance, but the measurement cost is high, the operation is complicated, and the reliability of the equipment is low; laboratory measurement has the characteristics of low cost and convenient operation, but due t...
