The invention belongs to the field of LNG equipment, and relates to the technology of floating stopping devices, in particular to a floating stopping device for an LNG liquid tank, which comprises a tank body, a floating stopping gap is formed between the inner walls of the tank body, a cover plate is fixedly installed between the inner walls of the floating stopping gap, and a floating stopping mother plate and a floating stopping top plate which are symmetrical are fixedly installed on the inner wall of the floating stopping gap. A processor is arranged on the side surface of the tank body;the processor is in communication connection with a floating stopping detection module, a matching module, a safety detection module, a service life analysis module and a storage module. According tothe floating stopping device, the floating stopping detection module can detect and analyze the assembling gap between the floating stopping mother plate and the floating stopping top plate, and continuously detect and analyze the density and the surface flatness of the floating stopping mother plate and the floating stopping top plate when the assembling gap does not meet the use requirements, sothat the quality coefficient of the floating stopping device is obtained; and the quality coefficient is compared with a quality coefficient threshold value, and the quality grades of the anti-floating mother plate and the anti-floating top plate are evaluated.

    本发明属于LNG设备领域,涉及止浮装置技术,具体是一种LNG液罐止浮装置,包括罐体,所述罐体内壁之间开设有止浮间隙,所述止浮间隙内壁之间固定安装有盖板,所述止浮间隙内壁固定安装有两个相对称的止浮母板与止浮顶板,所述罐体侧面设置有处理器;所述处理器通信连接有止浮检测模块、匹配模块、安全检测模块、寿命分析模块以及存储模块。本发明通过设置的止浮检测模块可以对止浮母板与止浮顶板的装配间隙进行检测分析,并且在装配间隙不满足使用要求时继续对止浮母板与止浮顶板的密度以及表面平整度进行检测分析,得出止浮装置的质量系数,将质量系数与质量系数阈值进行对比,对止浮母板与止浮顶板的质量等级进行评定。
