除此之外，连接单元7包括与外壳601内圈内侧壁滑动连接的圆弧形结构的连接杆702，且连接杆702沿外壳601的轴线方向滑动，连接杆702的两端均滑动套接有与相邻防护板901顶部固结的第三导向管701。
值得说明的，移动车1内部设置有中空结构的存储腔，移动车1的底部安装有用于移动的滚轮。
更进一步的，升降组件2包括与移动车1活动套接的第一升降管102，且第一升降管102相对移动车1沿竖直方向滑动，第一升降管102伸出移动车1顶部的一端滑动套接有沿其长度方向移动的第二升降管103，且第二升降管103伸出第一升降管102的一端与推动组件3底部固接，第二升降管103的内圈螺纹套接有第一转动管104，第一转动管104底部内圈滑动套接有沿其长度方向滑动的转接杆105， 转接杆105的底部固接有与主动杆106，主动杆106的外圈滑动套接有与第一升降管102内圈螺纹套接的第二转动管101，第二转动管101伸出第一升降管102的一端外圈固接有驱动机构107。
实施例一：
驱动机构107包括与第二转动管101底部外圈固定套接的齿轮圈，齿轮圈的一侧啮合有第二齿轮，第二齿轮的内圈固定套接有第一转轴，第一转轴的底部安装有与移动车1存储腔底部内侧壁固接的第一电机，齿轮圈的一侧安装有与第二转动管101活动套接的保持板，且保持板与存储腔内侧壁固接，主动杆106伸出第二转动管101底部的一端固接有与存储腔底部内侧壁固接的第二电机；
实施例二：
转轴508伸出推动组件3输出端的一侧安装有第三电机，存储腔的内部安装有控制器和蓄电池，移动车1的一侧安装有显示器、电源接口、数据接口和船型开关，推动组件3采用推杆电机，控制器采用ARM单片机，控制器与第一电机、第二电机、推杆电机、第三电机、蓄电池、显示器、电源接口、数据接口和船型开关电连接。
工作原理：首先将装置放置待检测的电缆一侧地面上，之后根据电缆与地面的位置高度，控制器控制第一电机，当第一电机启动的时候，带动第一转轴转动，使第二齿轮和齿轮圈转动，之后第二转动管101转动，第二转动管101转动的时候在螺纹作用下，第一升降管102沿竖直方向向上运动，此时由于第二电机没有启动，主动杆106不转动，使得转动杆105和第一转动管104均不转动，此时第一转动管 104和第二升降管103之间的螺纹达到锁死效果，在第一升降管102向上运动的时候将位于其顶部的推动组件3向上推动，这时候推动组件3底部的第二升降管103随推动组件3的带动下向上运动，同时转动杆105沿第一转动管104内圈向下滑动；
为了确保推动组件3升降平稳，移动车1顶部开设有与其内部存储腔连通的滑道，且滑道与第一升降管102滑动套接，第一升降管102的外圈和第二升降管103的外圈均固接有沿竖直方向设置的引导条，且通道的内圈以及第一升降管102的内圈均预留有与引导条滑动套接的引导槽，同时转动杆105的横截面与第一转动管104内圈横截面均为正多边形结构，从而确保转动杆105、第一转动管104随主动杆106同步转动；
当第一电机启动之后使第一升降管102向上运动的之后，还需要向上调整推动组件3的位置的时候，第二电机启动，带动主动杆106转动，从而在转动杆104的带动下第一转动管104转动，第一转动管104在螺纹作用下使第二升降管103向上运动，实现推动组件3的二次升降；
在检测的时候，位于转轴508上的第三电机启动，使与转轴508固定套接的活动连接板509向下偏转，然后位于下方的罩壳501向位于上方的罩壳501远离的方向转动，从而将检测机构5打开，使两组圆弧形结构的罩壳501向相互远离的方向运动，从而使与之连接的外壳601向相互远离的方向移动，同时在开启的时候，由于底部的外壳601相对顶部外壳601相对移动，由于位于底部外壳601上的推动单 元8上的推动板802与顶部外壳601内侧壁固接，位于顶部外壳601上的推动单元8上的推动板802与底部外壳601内侧壁固接，在两组外壳601向相互远离的方向运动的时候，位于顶部外壳601上的推动单元8上的推动板802相对顶部外壳601向下运动，位于底部外壳601上的推动单元8上的推动板802相对底部外壳601向上运动，这时候两组推动单元8上的推动板802相对齿轮905移动，从而均带动防护单元9上的齿轮905转动，然后齿轮905带动螺杆904转动，在螺杆904的作用下，使活动杆903向罩壳501的方向运动，从而带动防护板901向罩壳501的方向运动，在连接单元7的带动下，同一个外壳601开口处的防护板901同步移动，在防护板901移动的时候，位于外壳601上的推块907将防护板901向外壳601的开口处外侧推动，从而使移动至罩壳501开口处的防护板901能够覆盖在罩壳501的开口处，从而对罩壳501的开口处进行封堵，有效的避免检测的时候异物灰尘从罩壳501的开口处进入，避免灰尘异物粘附在磁芯502的两端以及接触块505上，有效避免磁芯502和接触块505接触不良的情况出现，提高检测组件4的防护强度和质量；
当检测机构5开启之后推动组件3启动将检测组件4向待检测的电缆的方向运动，使电缆处于罩壳501的内圈中间位置，之后转轴508上的电机启动，安装上述相反的步骤，使两组罩壳501向相互靠拢的方向运动，使检测机构5合拢形成圆环形结构将检测电缆包覆在其内圈，在合拢的时候上下方罩壳501上的磁芯502向抵触，接触块505向抵触，同时上方罩壳502外圈的线圈503的一端与上方罩壳502 其中一个接触块505连接，上方罩壳502外圈的线圈503的另一端与接线管506其中一个接线柱连接，连接管506的另一个接线柱并联有一电阻和电容，电阻和电容的另一端均与上罩壳501的另一个抵触块505固接，同时位于下方罩壳501的线圈503的两端分别与下方罩壳501上的接触块505连接，当合拢的时候，上下方的磁芯502上的线圈503形成一个导通的检测回路；
在检测的过程中在罩壳501和外壳601相互远离的一侧外侧壁镶嵌接触开关，当检测组件4运动至用于放置线缆的托架的时候，接触开关被触发，这时候转轴508上的第三电机启动，首先将检测机构5开启，然后推动组件3启动，将检测机构5向电缆远离的方向移动，之后移动车1前进，跳过安装电缆的托架位置，然后安装上述方式继续进行检测；
综上所述该设计能够实现对电缆金属护层的环流的自动快速检测操作，在检测的时候自动跳过安装电缆的托架，有效的避免异物灰尘在操作的时候进入检测机构的内容，提高防护功能和质量，方便对接地电缆金属护层的环流进行检测，提高检测效率，降低劳动强度。
