摘要
新型磁悬浮检波器采用磁悬浮技术替代传统振动传感器中的弹簧或簧片,增大探测频带宽度,提高探测灵敏度。磁悬浮次声波检波系统具有机动灵活、成本低、用途广、操作简单的优势,在地下管道渗漏、设备设施运行监测等行业应用广泛。新型磁悬浮检波器被创新性地应用于地体工程渗漏的调查,证实了该设备在地下动水检测方面具有一定优势。
A new magnetic levitation detector is an instrument using technology of magnetic levitation,instead of traditional vibration sensor using spring or reed. The magnetic levitation detector increases detection frequency band width and improves detection sensitivity. Furthermore,a system of maglev infrasound detection possesses advantages of moving flexible,low cost,widely used and simple to operate. It has been widely used in fields like underground pipeline leakage,monitoring operation of equipment and facilities,with significant importance. The maglev detector is pioneering applied in investigation of seepage of ground engineering objects. Results of the investigation prove that the equipment has good advantages in the detection of underground moving water.
