摘要
水电厂尾水闸门在出现事故、检修等紧急工况时下落,保证机组的安全,其重要性不言而喻。针对某水电厂尾水闸门抓梁放不到,挂不上闸门的情况,本文采用三维声学成像声呐技术对尾水闸门门槽进行了详细的测量。测量结果显示三维成像声呐技术不仅能够精确测量门槽数据,而且能够提供清晰的三维图像,可快速有效地检测水电站尾水闸门门槽,在水库、堤防等工程水下结构测量领域有广阔的应用前景。
The tail lock of hydropower plant falls down under emergency conditions such as accident and overhaul to ensure the safety of the unit. In this paper,a three-dimensional acoustic imaging sonar technique is used to measure the tail lock gate slot in detail. The measurement results show that the 3 D imaging sonar technology can not only accurately measure the tail lock gate slot data,but also provide a clear three-dimensional image. It can quickly and effectively detect the tail lock gate slot of the hydropower station. It has a broad application prospect in the field of underwater structure measurement,such as the reservoir and the embankment.
