海洋XBT投放系统中探头插销自动拔取机构设计

针对现有人工手持式投弃式温度深度剖面仪（XBT）探头投放方式存在的人为因素对测量的干扰等问题，设计了一种用于XBT自动投放系统的探头插销自动拔取机构。通过杠杆对力的放大作用，实现在有限行程范围内的探头插销自动拔取。实验结果表明，该机构有效可靠，投放成功率达到95%以上，投放平均时间节省50%以上，并可通过简单的外形或接口调整用于多种探头自动投放系统中，应用范围较广。

Design of an automatic drawing mechanism of probe plug in marine Expendable Bathythermograph launching system

According to the problems of the handheld launching method of expendable bathythermograph (XBT) , such as measurement disturbances from operators, an automatic drawing mechanism for the probe plug in the sea trials was proposed in this work. The lever was adopted here to magnify the tensile force in order to draw out the plug in limited stroke, which would make sure the full-automatic launching of expendable probes. The effectiveness and reliability of this mechanism has been verified by the corresponding laboratory tests. The success rate of probes deployment is over 95% and the mean time of the operation time is shortened more than 50%. The mechanism can also be used into various automatic launchers of expendable probes through a little configuration adjustment, which has a wide field of applications.
