The invention provides an in-situ layered acoustic measuring sampler detection system, comprising an in-situ measuring head, a synchronous sampling tube and a master control case, wherein the in-situ measuring head is fixed on the outer wall of the bottom end of the synchronous sampling tube, the master control case is arranged on the top end of the synchronous sampling tube, a sampling hole is formed in the synchronous sampling tube, and a sediment sample collecting tube is installed in the sampling hole. The system further comprises a sampling valve which is mounted on the bottom end of the synchronous sampling tube, a radio communication unit, an attitude detection unit, an penetration state and bottoming stability detection unit and an accelerometer, wherein the attitude detection unit comprises a gyroscope and an inclination sensor. Thus, the in-situ layered acoustic measuring sampler detection system can detect the attitude and position of a sampler in the process of sinking in a seabed, especially the state of the sampler from beginning to stabilization of penetration of the sampler into seabed sediments, which facilitates rapid determination of distribution of the seabed sediments which are measured via in-situ acoustics and synchronously sampled along the longitudinal direction of the seabed, makes possible identification of demarcation points between seawater and the seabed sediments and is beneficial for further research on the seabed sediments.
Description
technical field [0001] The invention relates to the technical field of marine monitoring, in particular to an in-situ layered acoustic measurement sampler detection system. Background technique [0002] Seabed sediment, as the lower boundary of underwater acoustics, undertakes the acoustic boundary and sound wave propagation layer necessary for engineering practice and scientific research such as exploration and exploitation of marine mineral resources, ship and submarine navigation, detection of submarine geological structures, and marine engineering construction. It is very important in sound field forecasting and matching field positioning. The current sampler does not have a detection system, but simply samples the seabed sediments, and cannot detect the distribution of the seabed sediments, which is not conducive to further research on the seabed sediments. Contents of the invention [0003] The purpose of the present invention is to propose a detection system for in...
