在布置竖直磁棒测量磁场分量时，需要挖较深的坑，在填埋磁棒的过程中非常容易导致磁棒晃动而引起角度误差，当磁棒固定在地表时，磁棒又会受到风力的影响而产生晃动，影响磁场分量的正常测量；
在布置水平磁棒时，不仅需要使水平磁棒处于特定的方向，还得使水平磁棒保持在水平状态，布置起来十分的麻烦，费时耗力；
市面上也有一些针对于磁棒安装设计的支架，但是这些支架一方面只能单独的针对水平安装或者竖直安装，局限性较大，另一方面整体结构也较为复杂，效率低下；
基于此，我们提出了一种大地电磁用磁棒平稳测量安装支架，希冀解决现有技术中的不足之处。

竖直调节组件设置在竖直固定板21与水平固定板13之间，用于调节使竖直磁棒处于竖直状态，或调节竖直固定板21与水平固定板13之间的间隔。竖直调节组件包括与竖直固定板21螺纹连接的丝杆19，丝杆19的底端通过轴承18与水平部转动连接，丝杆19的顶端设 有转把20，丝杆19、轴承18以及转把20在竖直固定板21与水平固定板13之间设置有三套。竖直固定板21的底面还设有压垫22，当确定好水平磁棒的位置时，可通过竖直调节组件将竖直固定板21底面的压垫22压在水平磁棒上，以固定水平磁棒的位置，防止水平磁棒晃动。插座23顶部设有安装板26，安装板26上开设有罗盘槽27，罗盘槽27的底部开设有与插座23连通的通槽。罗盘槽27内可放有罗盘，从而可通过罗盘与水平固定板13上的刻度配合，调节水平磁棒的角度；亦可放置有水平尺14，从而用于检测竖直磁棒的安装精度。。
在具体使用的时候，可通过三组安装支架分别对两个水平磁棒和一个竖直磁棒进行安装固定，亦可通过一组安装支架同时固定一个水平磁棒和一个竖直磁棒，利用另一组安装支架固定另一个水平磁棒，达到安装固定磁棒的目的。
在磁棒安装之前，首先需要通过插杆2将整体支架***地面，固定柱底板1的位置。
在安装水平磁棒的时候，先把磁棒放置在托槽17内，然后利用转动水平调节组件的螺纹套7，结合水平尺14将水平固定板13调节至水平，之后转动转盘15依照罗盘槽27内的罗盘和水平固定板顶部的刻度对水平磁棒的角度进行调节，确定水平磁棒的水平以及角度后，通过转动竖直调节组件的转把20使丝杆19转动，将竖直固定板21下降，使压垫22压住水平磁棒，完成水平磁棒的固定。
在安装竖直磁棒的时候，先通过转动旋钮36将挤压板31之间的环形空间展开，然后将磁棒从罗盘槽27内***至插座23的插槽24内，之后通过转动旋钮36，带动螺旋盘28转动，使移动块29向螺旋盘28的中心运动，令挤压板31紧压固定柱磁棒，完成竖直磁棒的固定。固定之后，最后通过微调竖直调节组件，竖直固定板21的位置进行调整，使竖直磁棒处于竖直的状态。
在磁棒安装完成后，通过螺旋把保护罩5底部的翼沿4固定在安装环3上，进而对保护罩5内的结构进行保护。
上述实施例只是为了说明本发明的技术构思及特点，其目的是在于让本领域内的普通技术人员能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡是根据本发明内容的实质所做出的等效的变化或修饰，都应涵盖在本发明的保护范围内。
