Problems solved by technology

[0006] At present, the deployment and recovery of the OBS device has become a technical problem in this field: (1) Since the interior of the OBS device is packaged as a glass ball, strict requirements are placed on the impact force at the moment of bottoming; (2) Due to the working principle of the OBS device In order to ensure the credibility of the observation data, the OBS device after deployment needs to be well coupled with the seabed; (3) It is difficult to ensure the separation of the counterweight by a single acoustic release device

Abstract

The invention relates to submarine seismic observation, in particular to a submarine seismograph laying recoverer and a method. The submarine seismograph laying recoverer comprises a deep sea lander frame, an acoustic release mechanism, a floating body material, a communication detection instrument and an OBS device, and the deep sea lander frame sequentially comprises a communication detection instrument mounting frame, a floating body material mounting frame, an OBS mounting frame and a one-way latch mounting frame from top to bottom; the communication detection instrument mounting frame, the floating body material mounting frame, the OBS mounting frame and the one-way latch mounting frame are all fixedly connected with the vertical supporting rods, and the balance weight is located at the bottom of the frame and connected with the acoustic release mechanism. The OBS device is arranged and recycled, the one-way clamping teeth are arranged between the OBS device and the seabed, the OBS device is prevented from directly colliding with and making contact with the seabed, meanwhile, the OBS device and the seabed are well coupled, and the working quality is guaranteed.

Description

technical field [0001] The invention relates to submarine seismic observation, in particular to a submarine seismograph deployment recovery device and method. Background technique [0002] The deep seabed can be used to observe the evolution process of the crust and even the mantle, and to deeply explore the internal structure of the earth. Therefore, the deep-sea seabed is the best place for crustal structure, movement observation, and natural disaster prevention. [0003] Ocean Bottom Seismometer (OBS) originated in the 1960s and 1970s. It is mainly used for artificial or natural seismic observations at sea. It is widely used in oil and gas resource exploration, offshore engineering, and earth structure. . [0004] All countries in the world have carried out independent research and development of OBS. Although there are some differences in type and function, the difference in structure and working principle is relatively small. OBS is generally composed of seismograph,...
