一种储罐罐底与壁面接触的直角区域检测装置
摘要：
本发明公开了一种储罐罐底与壁面接触的直角区域检测装置，属于储罐缺陷检测装置技术领域。该检测装置包括直角衔铁、第Ⅰ磁铁、第Ⅱ磁铁、传感器、中央处理器和显示系统。该检测装置能够对储罐罐底与壁面接触的直角区域进行全面扫描，通过对漏磁数据的采集、处理和显示，能够对储罐罐底与壁面接触的直角区域的缺陷位置和尺寸给出准确的量化结果，为储罐维修决策提供依据。该检测装置能够使检测精度达到壁减的25%。
摘要（英）：

The invention discloses a device for detecting right-angle region formed by bottom of storage tank and wall surface and belongs to the technical field of storage tank flaw detection devices. The detection device comprises a right-angle armature, a first magnet, a second magnet, a sensor, a central processing unit and a display system. The detection device can be used for comprehensively scanning the right-angle region formed by bottom of storage tank and wall surface, through the magnetic flux leakage data acquisition, processing and display,giving out accurate quantification results for the position and the size of the flaw at the right-angle region formed by bottom of storage tank and wall surface and providing reference for a storage tank maintenance decision. The detection device can be used for ensuring that the detection accuracy is up to 25% of wall thinning.
