Description

一种可自动化折叠的孔压探杆装置及其工作方法 技术领域
本发明涉及海底探测技术领域，具体而言，特别涉及一种可自动化折叠的孔压探杆装置及其工作方法。
背景技术
我国是全世界受海洋灾害影响最严重的国家之一，海洋灾害具有灾种多、分布广、频率高和防范难度大等特点。近年来，受全球气候变化的影响，阵发性强、持续时间长和波及范围广的极端风暴海况发生频率显著增加、强度屡破历史记录。极端风暴条件下的波浪和海流等环境荷载作用于海底表层土体，所造成的海底局部冲刷、土层液化和变形滑动易导致平台失稳倾覆。其中土层液化在我国黄河水下三角洲地区频发，可造成海洋构构筑物桩基础承载力下降、海床失稳滑坡，由此判断土层液化及揭示特征成为黄河水下三角洲防灾减灾的重点工作之一。
极端风暴条件下土层液化是指土层内部孔隙水压力累积，土体总应力不变，有效应力降低，导致土层丧失强度，使土体呈流体态。因此监测极端风暴条件下土层内部孔隙水压力响应成为判断土体液化、揭示液化机制的重要手段之一。目前关于海床内部孔隙水应力监测装置的研发较多，多采用杆体贯入方式。这种杆体贯入方式的装置，其贯入深度往往受限于设备尺寸，同时装置复杂且昂贵。

贯入系统包括储杆轮、储杆轮电机、旋紧机构、贯入驱动马达、一级传动齿轮、固定支架、固定螺栓、摩擦轮；旋紧机构包括探杆限位桶、旋转轴、液压机、旋转驱动液压机、液压传动杆、连接头、可旋转固定架、固定架、支撑柱和旋转架，旋转驱动液压机一端焊接于贯入支撑架上，另一端连接有液压传动杆，旋转轴上端连接旋转驱动液压机的液压传动杆，旋转轴下端焊接有旋转架，旋转驱动液压机可驱动液压传动杆的水平移动，带动旋转架的旋转，旋转架上表面固定有液压机，其一端连接有液压传动杆，并通过连接头与可旋转固定架连接，通过液压机可带动液压传动杆的水平移动，使得可旋转固定架旋转，下端的模块化的孔压探杆由摩擦轮加紧，探杆限位桶通过4个支撑柱连接于旋转架上表面；
储杆轮由正五边形钢架构成，包括固定链和限位板，储杆轮上焊接有固定链，一端固定于储杆轮上，一端固定于孔压探杆末段，限位板设置于五边形钢架转角处，储杆轮的中心通过其轮轴连接于储杆轮支撑架上，储杆轮电机焊接于储杆轮支撑架一侧，并通过储杆轮电机的转轴连接储杆轮，储杆轮电机带动储杆轮的转动，贯入驱动马达包括两个电力驱动的电机，分别焊接于贯入支撑架两侧，两个贯入驱动马达通过电机的转轴与一级传动齿轮连接，为两个摩擦轮的转动提供动力，两个相同大小的固定支架通过固定螺栓固定于贯入支撑架内的两端，左、右两端的固定支架上连接有若干的传动齿轮，实现两个摩擦轮的反向旋转；
量测系统包括孔压探杆、孔压探杆控制舱、CPTU探头、孔压传感器、探杆连接件、连接件外螺纹、连接件内螺纹、卡条、连接螺栓、水密插件公头、水密插件母头及数据传输与供电缆绳、位移传感器、甲板单元；孔压探杆分为1米等距的五段，每段内部设置有孔压传感器(304)，水密插件公头位于孔压探杆顶部，水密插件母头位于孔压探杆底部，孔压探杆控制舱焊接于储杆轮支撑架一侧，每段孔压探杆之间通过探杆连接件连接，CPTU探头位于孔压探杆的最底部，位移传感器位于孔压探杆中部。
作为优选方案，六边形支撑框架通过316L不锈钢材质的空心圆柱管焊接而成。
作为优选方案，支撑底座为四个等大的圆盘。
作为优选方案，分离机构还包括支撑腿固定螺母，支撑腿固定螺栓、上卡槽和下卡槽，支撑腿环扣内部开有上卡槽和下卡槽，用于固定上支撑腿和下支撑腿的顶端凸起，支撑腿固定螺母及支撑腿固定螺栓位于支撑腿环扣之上，用于箍紧支撑腿环扣。
作为优选方案，位于贯入支撑架左端的固定支架上固定有二级传动齿轮、三级传动齿轮及摩擦传动齿轮，贯入时，贯入驱动马达带动一级传动齿轮转动，同时通过二级传动齿轮、三级 传动齿轮及摩擦传动齿轮之间的齿轮咬合，可使传动杆及连接于传动杆上的摩擦轮转动；右端的固定支架上多设有一个尺寸与三级传动齿轮相同的四级传动齿轮，四级传动齿轮可改变右侧摩擦传动齿轮转动方向，由此实现两个摩擦轮的反向旋转，并通过摩擦作用将孔压探杆贯入至预定深度。

一种可自动化折叠的孔压探杆装置其工作方法，具体包括以下步骤：
S1:连接装置的数据传输与供电缆绳与船载的甲板单元及电源，确保孔压探杆存储在储杆轮，然后通过船载绞车将可自动化折叠的孔压探杆装置布放于平稳的海床表面；
S2：设备布放平稳后，打开甲板单元，向装置的贯入系统提供电力及贯入指令，贯入过程需要储杆轮电机、位移传感器、旋紧机构及贯入驱动马达的协同作用；
S3：贯入指令下达后，储杆轮电机带动储杆轮旋转并以20±2mm/s的速度将孔压探杆不停送入旋紧机构，此时旋紧机构将不会工作。同时两个贯入驱动马达共同转动，并带动摩擦轮将孔压探杆以20±2mm/s的速度连续贯入土体；
S4：当贯入深度达1米后，位移传感器将探杆运动距离反馈至孔压探杆控制舱，孔压探杆控制舱控制储杆轮电机及贯入驱动马达停止转动的同时，并控制旋紧机构开始工作，其中下端模块化孔压探杆由两个摩擦轮固定，防止转动，而旋紧机构上的液压机首先带动液压传动杆的水平移动，使可旋转固定架旋转，减少可旋转固定架与固定架间的间距，以固定上端模块化孔压探杆，然后旋紧机构上的旋转驱动液压机驱动液压传动杆的水平移动，从而带动旋转架的旋转，以此带动上端模块化孔压探杆旋转，旋转角度为30°；
S5：探杆连接后，旋紧机构会将指令反馈至孔压探杆控制舱，由此孔压探杆控制舱继续操控储杆轮电机及贯入驱动马达工作，将探杆贯入土体中，以此重复不断接杆，完成贯入过程。
S6：贯入完成后即可开始进行原位观测工作，数据储存于孔压探杆控制舱。
本发明由于采用了以上技术方案，与现有技术相比使其具有以下有益效果：
(1)解决了海底垂直剖面孔隙水压力监测的难点。本装置采用摩擦贯入方式，通过装置的贯入系统，将孔压探杆贯入至预定深度，可探测海床内部0-5米范围内的孔隙水压力，可判断极端风暴条件下海床液化的发生。同时孔压探杆头部设有CPTU探头，可实现海床0-5米范围内的土体力学性质探测；
(2)解决了由于孔隙水压力探杆过长而导致整体设备庞大、稳定性降低的难题。本装置将孔压探杆进行模块化，进行自动化折叠，不仅降低监测装置的整体高度，还提高了整体装置的稳定性，为海床孔隙水压力长期在位监测提供安全保障。
(3)解决了观测装置因掩埋而难以回收的难点。极端风暴事件频发时，长期在线原位监测装置的支撑底座极易发生沙土掩埋事件，从而大幅增加装置整体回收时的阻力。本装置将支撑底座与装置主体设计为分离模块，支撑底座掩埋时，通过潜水员打开分离机构，即可实现支撑底座与装置主体分离。

  7. 如权利要求1-6之一所述的一种可自动化折叠的孔压探杆装置的工作方法，其特征在于,具体包括以下步骤：
    S1:连接装置的数据传输与供电缆绳(312)与船载的甲板单元(314)及电源，确保孔压探杆(301)存储在储杆轮(201)，然后通过船载绞车将可自动化折叠的孔压探杆装置布放于平稳的海床表面；
    S2：设备布放平稳后，打开甲板单元(314)，向装置的贯入系统提供电力及贯入指令，贯入过程需要储杆轮电机(202)、位移传感器(313)、旋紧机构(203)及贯入驱动马达(204)的协同作用；
    S3：贯入指令下达后，储杆轮电机(202)带动储杆轮(201)旋转并以20±2mm/s的速度将孔压探杆(301)不停送入旋紧机构(203)，此时旋紧机构(203)将不会工作；同时两个贯入驱动马达(204)共同转动，并带动摩擦轮(212)将孔压探杆(301)以20±2mm/s的速度连续贯入土体；
    S4：当贯入深度达1米后，位移传感器(313)将探杆运动距离反馈至孔压探杆控制舱(302)，孔压探杆控制舱(302)控制储杆轮电机(202)及贯入驱动马达(204)停止转动的 同时，并控制旋紧机构(203)开始工作，其中下端模块化孔压探杆(301)由两个摩擦轮(212)固定，防止转动，而旋紧机构(203)上的液压机(2032)首先带动液压传动杆(2034)的水平移动，使可旋转固定架(2036)旋转，减少可旋转固定架(2036)与固定架(2037)间的间距，以固定上端模块化孔压探杆(301)，然后旋紧机构(203)上的旋转驱动液压机(2033)驱动液压传动杆(2034)的水平移动，从而带动旋转架(2039)的旋转，以此带动上端模块化孔压探杆旋转，旋转角度为30°；
    S5：探杆连接后，旋紧机构会将指令反馈至孔压探杆控制舱，由此孔压探杆控制舱继续操控储杆轮电机(202)及贯入驱动马达(204)工作，将探杆贯入土体中，以此重复不断接杆，完成贯入过程；
    S6：贯入完成后即可开始进行原位观测工作，数据储存于孔压探杆控制舱(302)。
