实施例 1
如图1-图12所示，本实施例提供了一种智能钻柱2，包括钻柱本体1、纳米发电机110、传感器单元111、电源单元19和主控单元18；
钻柱本体1包括钻柱上接头11、钻柱下接头16和钻柱管体15，钻柱上接头11设置在钻柱管体15的一端，钻柱下接头16设置在钻柱管体15的另一端；
钻柱下接头16上设有若干安装单元孔117，纳米发电机110、传感器单元111、电源单元19和主控单元18分别单独位于对应的安装单元孔117内；
具体的，图4和图5中安装单元孔117的数量为四个，安装单元孔117的数量可以根据实际需求和工况进行布置；
在此基础上，安装单元孔117还可以同时安装在钻柱下接头16和钻柱下接头11上；
在有更大的功率需求时，还可以在钻柱上接头11上设置纳米发电机110和电源单元19；
还可以在钻柱上接头11上额外设置传感器单元111，使得钻柱上接头11上的传感器单元11和钻柱下接头16上的传感器单元111可以测量不同的物理参数或测量关键的相同的物理参数；
相邻安装单元孔117之间设有第一过线孔113，第一过线孔113内设有第一线缆114，第一线缆114用于电气连接纳米发电机110、传感器单元111、电源单元19和主控单元18；
具体的，纳米发电机110为纳米压电发电机或纳米摩擦发电机；纳米发电机110可以通过钻井液流经管柱时形成的波动压力或钻柱钻进时产生的机械振动进行发电，产生的电能一般为交流电；
电源单元19包括整理电路和电源管理模块，整理电路可以将纳米发电机110产生的交流电整流成可利用的直流电，电源管理模块可以将整流的直流电传输给主控单元18和传感器单元111进行利用；
同时电源管理模块还可以为主控单元18和传感器单元111进行供电，
或者；电源单元19还可以包括可充电电池，纳米发电机110整流换成的直流电可以为可充电电池进行充电，当井下无钻井液循环以及钻进时，此时纳米发电机110无法工作，就可以通过电源单元19中的可充电电池为主控单元18和传感器单元111进行供电；
钻柱管体15、钻柱上接头11和钻柱下接头16上均布置有第二过线孔13，第二过线孔13沿钻柱本体1长度方向设置，钻柱上接头11上设有上部天线安装环槽116，钻柱下接头16上设有下部天线安装环槽115，上部天线安装环槽116通过第二过线孔13与对应的一个安装单元孔117连通，下部天线安装环槽115通过第二过线孔13与对应的一个安装单元孔117连通；

钻柱管体15的钻柱管体内表面120灌注有化合物保护层119，具体的，化合物包括环氧树脂、橡胶或聚氨酯；
在本实施例中，因为钻柱管体内表面120的厚度太薄不适宜进行开孔，因此通过灌注化合物保护层119的方式进行隔绝；
在实施化合物保护层119时，先把第二线缆14依托重力放置在钻柱管体15的底部，化合物保护层119在施工时具备流动性，灌注在钻柱管体15内部后，沿重力平铺流动，当有足够的量后，就可以覆盖过第二线缆14，并具备一定的保护厚度，同时与钻柱管体内表面120有足够的接触面。
本实施例还提供了一种井下数据传输系统，包括地面系统、井下系统和至少两个上述的智能钻柱2；
相邻智能钻柱2之间通过钻柱上接头11或钻柱下接头16连接在一起，地面系统和井下系统通过智能钻柱2双向通讯连接；

主控单元18是一个小型的单片机系统，具备数据存储、传输和读写等功能，传感器单元111能够实时测量当下的钻柱或环境的物理量，例如流体压力、温度和振动等，主控单元18可以读取传感器单元111测得的物理量，储存数据，并与地面系统或其余的智能钻柱2上的主控单元18进行通信，传输数据；主控单元18利用上部线圈12和下部线圈17与邻近的智能钻柱2通过无线通信方式进行通信，该无线通信方式包括Wi-Fi，Wi-Fi Direct，蓝牙，低功耗蓝牙和ZigBee等；
至少两个智能钻柱2连接在一起后，每个智能钻柱2上的传感器单元111可以测量不同的物理量，也可以测量相同的物理量；
相邻两个智能钻柱2中，其中一个智能钻柱2上的上部天线安装环槽116与另一个智能钻柱2上的下部天线安装环槽115对接；
相邻两个智能钻柱2中，其中一个智能钻柱2上的上部线圈12与另一个智能钻柱2上的下部线圈17通讯连接；
如图6所示，当三个智能钻柱2连接在一起后，可以取消位于中间位置的智能钻柱2的传感器单元111，利用存储单元118代替传感器单元111，以存储更多的数据，此时位于中间位置的智能钻柱2就形成了中继存储点，地面系统可以只与中继存储点通信，中继存储点可以与相邻的智能钻柱2通信，实际组合结构可以根据现场需求来确定。
本实施例提供的一种智能钻柱2及井下数据传输系统的有益效果在于：
安装单元孔117能够为纳米发电机110、电源单元19、主控单元18和传感器单元111的安装提供安装位置，由于第一线缆114位于钻柱本体1的腔内，第一线缆114连接纳米发电机110、电源单元19、主控单元18和传感器单元111时需要从外向内进行安装，安装单元孔117能够方便纳米发电机110、电源单元19、主控单元18和传感器单元111的安装；
