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 deployment recovery device and method. Including deep-sea lander frame, acoustic release mechanism, buoyant material, communication detection instrument and OBS device, deep-sea lander frame from top to bottom includes communication detection instrument installation frame, floating body material installation frame, OBS installation frame and one-way bayonet installation The frame, the installation frame of the communication detection instrument, the installation frame of the floating body material, the OBS installation frame, and the one-way bayonet installation frame are all fixedly connected with several vertical support rods, and the counterweight is located at the bottom of the frame, and the counterweight is connected with the acoustic release mechanism. It realizes the deployment and recovery of the OBS device. By setting the one-way locking teeth between the OBS device and the seabed, it avoids the OBS device from directly colliding with the seabed, and at the same time enables a better communication between the OBS device and the seabed. coupling to ensure the quality of work.

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,...
