海底地震仪水下投放装置的设计
|
摘要
针对联合采集观测系统设计中对OBS精确布阵的要求,设计并制作了OBS水下投放装置。该装置通过机械运动机构和声学释放器的有机结合,并借助船载绞车的牵引和水下定位系统的引导,实现了在接近海底区域准确投放OBS的目的,投放精度达到20 m以内,成功率为95%。海上试验结果表明:该装置设计合理,工作可靠、安全,操作简便。水下投放装置在OBS布阵中的应用,为OBS阵列数据采集质量的提高提供了必要的条件。
For the requirements of accurate embattled OBS in the design of unite collection observation system,the underwater launch device of OBS is designed and produced.The device combines the mechanism and acoustic release unit and achieves the purpose of OBS accurate launch close to the seabed,which is towed by ship-borne winch and led by underwater localizer.The experiments show that the launch is within 20m accuracy with success probability 95%.The results also show that the device is reasonably designed,reliable,safe and easy to be operated.The application of underwater launch device improves OBS array data quality.
