摘要: 针对储氢气瓶金属内胆表面缺陷检测效率低、检测质量不佳等问题,研制了一种视频检测与涡流检测相结合并配备自动扫查机构的综合检测系统。该系统采用模块化设计,主要包括一体化检测装置、行进及居中对准机构、瓶体放置装置及控制盒等,结构紧凑且易于拆装,可实现气瓶瓶身部分的内壁螺旋扫查,同步保存涡流检测数据与视频图像数据,可根据时间信息定位缺陷实际位置。试验结果表明,该系统不仅缺陷检出率高,还可满足工业检测中的自动扫查要求,提高储氢气瓶内胆表面缺陷的检测效率。Abstract: In order to solve the problems of low efficiency and poor quality of the inspection of defects on the metal liner of hydrogen storage cylinders, an integrated inspection system combining eddy current inspection with video inspection and equipped with an automatic sweeping mechanism was developed. The system was modular in design and consisted of an integrated inspection device, a travel mechanism, a center alignment mechanism, a bottle placement device and a control box, etc. It was compact and easy to disassemble. The system enabled spiral sweeping of the inner liner surface of the cylinder body section, simultaneous storage of eddy current inspection data and video image data, and can locate the actual position of the defect based on time information. The test results showed that the system not only had a high defect detection rate, but also met the requirements of automatic sweeping in industrial inspection, and improved the efficiency of detecting surface defects on the inner liner of hydrogen storage cylinders.
