Abstract

The invention provides an ice area environment ocean bottom seismograph (OBS) recovery device and method, and belongs to the technical field of ocean exploration, the ice area environment ocean bottom seismograph recovery device comprises an underwater recovery device, an ocean bottom seismograph and a mother ship, and the upper part of the underwater recovery device is provided with a stranded wire seat. The device provided by the invention is a compact device, can realize grabbing operation of the slipknot under the monitoring of a camera with smaller volume and weight, so that the grabbing operation can be quickly completed with high reliability, and the recovery efficiency of the seismograph is improved; cleaning operation of the propeller is achieved through the dredging piece, and sundries are prevented from blocking the propeller and affecting use of the dredging piece; according to the underwater recovery device, a vertical propeller is used for applying periodic upward and downward alternating force, so that the seismograph is quickly released from the extrusion of crushed ice.

Description

technical field [0001] The invention relates to the technical field of marine exploration, in particular to a recovery device and method for an ocean bottom seismograph (OBS) in an ice area environment. Background technique [0002] Undersea seismographs are seismometers designed to observe microvibrations caused by earthquakes and other tectonic events on the ocean floor. Every year, our country sends polar scientific research ships to the polar regions to carry out the measurement of submarine earthquakes, and spends a huge amount of money every year to deploy submarine seismometers. Because there is no cable connection between the submarine seismometers and the mother ship, and the submarine earthquakes The amount of data collected by the instrument used to be so large that it could not be transmitted to the mother ship through sound waves. Therefore, the data stored by the submarine seismograph will mainly rely on the recovery of the data after the submarine seismograph ...
