Description

油井平台附近溢油监测装置及操作方法 技术领域
本发明涉及溢油监测设备技术领域，尤其是一种油井平台附近溢油监测装置及操作方法。
背景技术
现有采用探测油荧光(采用紫外光激发)的海洋溢油监测装置，基本采用光电二极管作为探测器，灵敏度极低，而油荧光信号比较微弱，探测装置离目标溢油水面较远时，例如在海上石油钻井平台使用，则无法探测到溢油的发生。有采用光电倍增管作为探测器的装置，采用氙灯作为激发光源，发光频率较低，不适合实时监测，对光源滤光片要求较高，只能实现某些高荧光油的探测，且经常对溢油现象发生误判。
发明内容
本发明针对现有技术的不足，提出一种油井平台附近溢油监测装置及操作方法，能实时监测海洋面溢油情况，避免大面积污染海洋面。
为了实现上述发明目的，本发明提供以下技术方案：一种油井平台附近溢油监测装置，包括发射模块、接收模块、自动对准模块和控制模块，
所述发射模块包括：
漂浮设备，用于使发射模块漂浮在海洋面上，所述漂浮设备包括推进模块， 所述推进模块位于所述漂浮设备上，用于驱动所述漂浮设备在海洋面上运动；

另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
如图1所示，本发明一个实施例，一种油井平台附近溢油监测装置，包括发射模块、接收模块、自动对准模块和控制模块，
所述发射模块包括：
漂浮设备，用于使发射模块漂浮在海洋面上，所述漂浮设备包括推进模块，所述推进模块位于所述漂浮设备上，用于驱动所述漂浮设备在海洋面上运动；
激光发射模块，固定在所述漂浮设备上，能发射激光信号；
所述接收模块包括：
激光接收模块，用于接收激光发射模块发出的激光信号；所述激光信号为海洋面反射过来的激光信号；所述激光接收模块可转动地固定所述油井平台上；
所述自动对准模块5包括：
测距模块，用于测量所述激光发射模块和所述激光接收模块的距离；
光传感器，用于感应所述激光发射模块发出的激光信号；
计算模块，根据光传感器感应到所述激光发射模块发出的激光信号方向，以及所述测距模块获得的所述激光发射模块和所述激光接收模块的距离，计算所述接收模块的转动角度，以使得所述激光发射模块对准所述激光接收模块；
所述控制模块根据所述激光接收模块接收由所述激光发射模块向沿所述接收模块方向的海洋面发射激光而发射的激光，若损耗的能量差大于海洋面无溢 油时的能量差，确认所述海洋面上有溢油。
上述油井平台附近溢油监测装置的操作方法，包括：
驱动漂浮设备在油井平台周围游弋；
利用测距模块，测量漂浮设备与油井平台之间的距离；再结合光传感器和计算模块，获得使得所述激光发射模块对准所述激光接收模块的角度和方向；
启动激光发射模块向海洋面倾斜向下发射激光，该激光在与海洋面接触时会产生发射现象，若该反射点被溢油覆盖，会造成激光损耗；
利用海洋面对激光反射，激光发射模块发出的激光经反射后被激光接收模块所述接收；
所述控制器根据所述激光接收模块收到的激光信息，与无溢油时的预设值进行比较，若该激光损耗的能量差大于无溢油时能量差，确认所述海洋面上有溢油。
由于深海采油的油井平台1，是安设零部件最多的位置，导致容易出现漏油现象，在油井平台1上设置激光接收装置12，同时在远离油井平台1的地方设置激光发射装置12，利用激光发射装置13对油井平台1附近海洋面4发射激光，产生发射光线至激光接收装置12。
在海洋面4无溢油污染的情况下，激光发射装置13发出的激光与激光接收装置12接收的激光，存在强度差(或能量差)，设定该差值为参考值。若海洋面4存在溢油时，由于激光在油污面与海洋面4上的损耗存在差异，必然使得上述强度差不同，若差值大于参考值，表明该海洋面4上存在油污。不然就没有被油污污染。上述强度差是通过油井平台1上的控制器11来操作完成。
所述发射模块设有若干个，分散在所述油井平台1上周围；相应的所述激光发射装置13和所述激光接收装置12设有若干个。采用若干个发射模块结合相应的激光发射装置13和所述激光接收装置12，分散在油井平台1周围，能快速对油井平台1周围的海洋面4进行监测，效率高。
所述发射模块设为可移动机构，相应的所述激光接收装置12为可活动地设在所述油井平台1上。
在选用小船结构的发射模块，可以以所述油井平台1为圆心转动，所述激光接收装置12在所述油井平台1上转动。对油井平台1周围进行全方位的监测，防止溢油扩散。
所述海洋面4溢油监测装置还包括自动报警装置，所述自动报警装置与所述控制器11连接，在确认所述海洋面4有溢油时，所述自动报警装置进行报警提示。由于上述监测过程可自动进行，结合自动报警装置，当检测到海洋面4上的油污存在，可及时提醒进行清污处理，防止进一步扩大污染面积。
所述激光发射模块和/或所述激光接收模块设有3-5个，可均匀分散在油井平台1的周围，或根据洋流方向或风向在下游设置较多的反射站2。
所述漂浮设备2、所述激光发射装置12和所述激光接收装置13为同步转动。对于游弋在油井平台1附近的反射站2，以提高检测的稳定性，同步转动使得检测效果更好。
所述转动为间歇式，每转动一次停止10s发射一次激光，每次转动7-13°。
所述监测装置包括无线通讯模块，用于将所述控制模块中信息传输至数据中心，例如云中心。
所述无线通讯模块优选包括Wi-Fi模块或移动网络模块。
本发明海洋面溢油监测装置，能对油井平台1附件的海洋面4进行实时监测，以免发生漏油现象而污染整个海洋环境。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
