The invention provides a mounting structure of a liquid cargo tank sensor. The mounting structure comprises a base fixed on a liquid cargo tank shell, a sensor assembly perpendicular to the liquid cargo tank shell is inserted into a bolt hole of the base, and a heat insulation layer covers the outer surface of the liquid cargo tank shell and wraps the sensor assembly. The sensor assembly comprises a probe, a fixing body and a spring body, and the spring body can provide support and can effectively compensate telescopic deformation of the sensor assembly caused by thermal expansion and cold contraction of the liquid cargo tank shell. The heat insulation layer comprises the first heat insulation layer, the second heat insulation layer and the third heat insulation layer which are mutually embedded, the heat insulation layers are mutually clamped, installation is convenient, and stability can be improved. The outer end portion of the sensor assembly is fixed through an aluminum foil covering the outer surface of the heat insulation layer and a fixing nut, a heat preservation sealing layer formed by polyurethane foaming is laid on the outer surface of the aluminum foil, and the sealing effect is guaranteed. The installation structure is simple in overall design, convenient to disassemble and maintain, good in sealing performance and suitable for large-scale application and popularization.
本发明提供一种液货舱传感器的安装结构,该安装结构包括固定于液货舱壳体上的底座,传感器组件垂直所述液货舱壳体插入底座的螺栓孔内,绝热层覆盖于液货舱壳体外表面并包覆传感器组件。传感器组件包括探头、固定体及弹簧体,弹簧体既能提供支撑,又能有效地补偿液货舱壳体热胀冷缩对传感器组件形成的伸缩变形。绝热层包括相互嵌合的第一保温层、第二保温层、第三保温层,保温层之间相互卡合,即便于安装,又能提升稳固性。传感器组件的外端部通过覆盖于绝热层外表面的铝箔片及固定螺母实现固定,铝箔片外表面敷设有聚氨酯发泡形成的保温密封层,保证了密封效果。该安装结构整体设计简单,拆修方便,同时具有良好的密封性能,适于大规模推广应用。
