Submarine geophysical data detection device

Abstract

The invention discloses a submarine geophysical data detection device, and belongs to the technical field of geophysical detection. A seabed geophysical data detection device comprises a base, the top of the base is connected with a cover body, a detector is arranged in the cover body, the cover body is provided with a pulling rope used for pulling a device body, a working groove is formed in the center of the bottom wall of the base, and a sampling mechanism used for sampling is arranged in the working groove; a mounting plate is arranged at the top of the base, a mounting groove is formed in the mounting plate, a counterweight ring is connected to the inner wall of the mounting groove and sleeves the outer wall of the base, a supporting plate is connected in the base, one end, far away from the mounting groove, of the counterweight ring abuts against the supporting plate, and an anchor body is connected to the bottom wall of the base; the counterweight ring is additionally arranged on the base, the stability of the device is guaranteed, the device is prevented from shaking on the seabed, stable sampling work can be conveniently carried out in the sediment detection process, seabed sediments are effectively sampled through the sampling mechanism, and the accuracy of data monitoring is guaranteed.

Description

technical field [0001] The invention relates to the technical field of geophysical detection, in particular to a seabed geophysical data detection device. Background technique [0002] The ocean is a dynamic, continuous, and fuzzy space-time information carrier. With the continuous development of detection equipment and information technology, there are more and more means of ocean data acquisition, which are generally obtained by collecting ocean sediments. Marine sediment refers to the general term for seabed sediments formed by various marine sediments. The substances deposited on the seabed with seawater as the medium can generally be divided into three different processes: physical, chemical and biological. Because of these Processes are often not carried out in isolation, so sediments can be regarded as geological bodies produced by comprehensive actions. At present, when data acquisition and detection of seabed sediments are carried out, detectors are usually used to...

Problems solved by technology

[0004] However, due to the large fluctuations in the seabed water flow, the above-mentioned device is fixed close to the anchor, which is easy to shake and has poor stabilization effect, which affects the normal operation of the sampling work, and the device scrapes the material through the scraper teeth during sampling, and the sediment is mixed with the seawater. Only a small part of the sediment falls into the sampling bucket, and the sampling sample is small and the effect is poor, which affects the detection and analysis of the data
