Abstract

双推动器系统的目的是对WER核发电厂的蒸汽发生器管道进行涡流检查。它的功能是能够将两个探针同步推动和拉动而通过蒸汽发生器管道。此种设备包括两个技术对等段，在附图中显示了仅仅一段。探针被带到角度导向器(7)并利用机构和轮系统(8)进一步推动通过设置有校准块的导向装置(4)而被推动。探针经过系统在图中以虚线显示。机构包括多种嵌齿轮和橡胶轮(8)。

Description

用于推动两个涡流探针同时通过核发电厂的两个蒸汽发生器管道的DPS双推动器系统
发明的描述
发明的应用领域
本发明的应用涉及用于对WER核发电厂的蒸汽发生器管道进行非-破坏性检查(涡流检查)的设备。其目的是能够将探针推动和拉动通过蒸汽发生器管道。
技术问题
由于重复发生的问题例如：探针不完全通过管道，延长检查周期，艰苦的工作状况，我们得知的结论是可以加速和改进整个程序。
受到这种初衷的启发，双推动器探针已经被开发，其可同时并独立地推动两个探针通过管道。
技术状态
当前，世界上可用于蒸汽发生器检测的少量的探针推动器有例如：在蒸汽发生器的外部设置具有驱动马达的单个推动器，蒸汽发生器内部设置有探针滚筒(drum)的双推动器，设置有初级外部驱动马达和次级内部驱动马达的单个推动器。
发明内容
发明的主要目的是尽可能地在保证质量和缩小时间段的情况下推动探针通过WER蒸汽发生器的管道。
为了实现主要目的，已经采用了双推动器的解决方案。
设备本身包括两个技术对等段。每个段设置有驱动单元(图1位置3)，其包括马达和减速单元。
探针产生角度导向器(图6，位置7)并利用机构和轮系统(图6，位置8)进一步被推动通过设置有校准块的导向装置(图1，图2位置4)。探针经过系统在图6中以虚线显示。机构包括多种嵌齿轮和小橡胶轮(图6，位置8)，其被驱动单元驱动。
检测的整个过程利用两个照相机(图3，位置6)进行监视，所述照相机与设备本身设置的探针的导向相邻。
探针双推动器系统(DPS)也设置有电子开关板(图1，位置2)和气动分离块(图1，位置5)。
探针双推动器系统(DPS)经由计算机控制室而被控制。它可以利用手动远程，半自动或完全自动进行操作。
附图说明：
包括在说明书中并构成本发明说明书一部分的特征附图，是用来说明本发明目前的优选实施方式，并且有助于呈现发明的基本原理。图1显示了处于闭合位置的设备的立体图。图2显示了处于打开位置的设备立体图，图3为设备的设计图。图4显示了设备的布局图，图5为外形视图。在图6中显示了通过系统的探针的经过图。
机构系统(图9)
双推动器的每个段设置有一个系统驱动机构。机构的作用(图9)为可以所需的速度平滑地驱动小轮(图9，位置2)。
整个过程在这样的模式中发生，即：驱动元件驱动位于轴(图9，位置1)的下端的嵌齿轮(图9，位置3)。轴的上端设置有小轮(图9，位置2)，设计成无滑动的推动探针。
如果必要的话，每个小轮都可以在执行过程中被独立地开始运作或停止运作。可通过气动气缸(图9，位置4)执行这种操作。
导向系统(图8)
导向的目的是在双推进器的输出处直接把探针伸入到蒸汽发生器管道中。导向可以被控制为闭合或维护或打开以及操作位置。通过气动气缸(图8，位置5)能够从一个位置传输到另一个位置。
导向(图8，位置1)的塑料管设置有内部校准块(图8，位置8)用于校准探针。接下来进行测量，具有感应线圈的塑料气缸(图8，位置9)设计成当流经它时可使得探针停止。
角度导向器系统(图7)
角度导向器的主要目的是确保探针在运动方向光滑地转变90度，设计显示在图7中。
在半径回转的内部定位了小轮(图7，位置1和位置2)，其被设计成在运动方向上确保尽可能小地摩擦变化。
