Description

一种钻探装置及其钻探方法 技术领域
本发明属于地外天体探测领域，具体地说是一种用于地外天体、针对原位探测方法使用的钻探装置及其钻探方法。
背景技术
自20世纪以来人类一直未停止对外太空的探测，多种探测手段也随着时代不断加深人类对地外天体的认识与理解；而原位探测通过直接将传感器置入地外天地以探测其土壤的物理成分等特征，是一种重要的地外天体探测手段。
原位探测往往需要将传感器布放于星壤表面以下，而传统的钻探方式往往需要携带较长的钻杆；因此直接导致钻探装置重量体积较大，不太适合于对有效载荷体积以及质量都有严格要求的航天任务。
发明内容
针对传统钻探方式存在的上述问题，本发明的目的在于提供一种冲击式贯入无人自动钻探装置及其钻探方法。
本发明的目的是通过以下技术方案来实现的：

所述安装筒包括依次螺纹连接的电机后盖、电机安装筒、轴承安装筒及冲击锤滑动套筒，所述电机位于电机安装筒内，输出端通过联轴器与轴系的一端相连，该轴系通过轴承转动安装于轴承安装筒内，所述凸轮与轴承安装筒之间留有供凸轮抬升的空间；所述冲击冲击锤可滑动地容置于冲击锤滑动套筒内；
所述外壳的上端连接有后盖，下端连接有头锥，该外壳内设有限位套，所述限位套的上端抵接于安装筒的下端，该限位套的下端抵接于外壳；

具体实施方式
下面结合附图对本发明作进一步详述。
如图1～4所示，本发明的钻探装置包括电机4、安装筒5、轴系7、凸轮8、冲击锤9、驱动弹簧10及外壳12，其中外壳12为内部中空结构，上端连接有后盖1、下端连接有头锥13，该头锥13可与外壳1为一体结构，或螺纹连接；后 盖1上有卡榫，外壳12的上端设有槽，卡榫卡入槽中、从而将外壳12与后盖1固定在一起。外壳12和头锥13以及后盖1组成的封闭壳体，钻探装置被外壳12所保护，不会受外界灰尘环境的影响；头锥13为锥状，有利于实施贯入。
安装筒5安装于外壳12内，包括由上至依次螺纹连接的电机后盖3、电机安装筒14、轴承安装筒15及冲击锤滑动套筒16，外壳12的内壁上胶结有限制安装筒5位置的限位套17，限位套17的上端抵接于冲击锤滑动套筒16的下端，限位套17的下端抵接于外壳12。
电机4、轴系7、凸轮8、冲击锤9及驱动弹簧10分别容置于安装筒5内，电机4固定在电机安装筒4内，轴系7通过轴承转动安装于轴承安装筒15内，轴系7的一端(上端)通过联轴器6与电机4的输出端相连，另一端(下端)设有支撑凸轮8的支撑部件。
凸轮8可沿轴向相对滑动地套设在轴系7上，在凸轮8上沿轴向开设有豁口19；凸轮8的底面沿轴向具有高度差，即凸轮8的底面由豁口19的一侧向另一侧轴向高度逐渐增加。凸轮8的底面通过支撑部件支撑，凸轮8上的豁口19的宽度大于支撑部件的宽度，该支撑部件在凸轮8处于初始状态时支撑于凸轮8底面的一侧，凸轮8在支撑部件转至豁口19处时带动冲击锤9进行释放。本发明的支撑部件为凸出于轴系7另一端外表面的挡块18。凸轮8与轴承安装筒15之间留有供凸轮8抬升的空间20。
冲击锤9的一端内部为中空结构，该端与凸轮8相连，轴系7的下端插入冲击锤9该端的内部，冲击锤9的另一端为冲击端。冲击锤9的另一端外部设有压板11，并且另一端外部套设有驱动弹簧10，驱动弹簧10的一端抵接于该压板11上，另一端抵接于冲击锤滑动套筒16。压板11与冲击锤9的另一端为一体结构，或通过与冲击锤9另一端螺纹连接的螺母21限位；本实施例的压板11与冲击锤9通过螺母21连接在一起。
外壳12上端的后盖1与安装筒5上端的电机后盖3之间的空隙内设有缓冲弹簧2，该缓冲弹簧2的两端分别与后盖1和电机后盖3抵接。驱动弹簧10压缩释放以后产生的反作用力产生的功则转化为缓冲弹簧2的弹性势能和安装筒5向上运动的动能。
本发明钻探装置的钻探方法为：
电机4驱动轴系7旋转，在转动过程中，该轴系7另一端的挡块18始终抵接于凸轮8的底面，带动凸轮8沿轴向抬升，进而通过凸轮8带动冲击锤9抬升，冲击锤9在抬升的过程中通过压板11向上挤压驱动弹簧10；凸轮8在挡块18转至豁口19处被释放，通过驱动弹簧10驱动冲击锤9撞击连接于外壳12下端的头锥13，提供外壳12向下贯入的冲击力。撞击后，再通过驱动弹簧10的弹力复位，凸轮8轴向高度较小一侧的底面复位至挡块18上方，再通过电机4驱动轴系7旋转，实现凸轮8带动冲击锤9进行抬升、释放循环。
