The invention discloses a liquefied natural gas tank body structure which comprises a shell, a secondary barrier object is arranged in the shell, a main barrier object is arranged in the secondary barrier object, a detection space is formed between the main barrier object and the secondary barrier object, and detection equipment is installed in the detection space. The detection equipment comprises a methane sensor and an alarm which are electrically connected, and the methane sensor is mounted in the detection space; a barrier space is formed in the shell, two partition plates are arranged inthe barrier space, and the barrier space is divided into three horizontally-distributed barrier units through the partition plates, and the three barrier units are the first main barrier unit, the second main barrier unit and the third main barrier unit respectively. The three main barrier units are arranged in the device, the early-stage manufacturing and fixing difficulty is small, the cost islow, and later-stage maintenance is convenient; a detection space is formed between the main barrier object and the secondary barrier object, and detection equipment can be installed in the detectionspace so as to detect gas leakage.

    本发明公开了一种液态天然气舱舱体结构,包括:外壳,所述外壳内部设置有次屏障物,所述次屏障物内设置有主屏障物,所述主屏障物和次屏障物之间形成有检测空间,所述检测空间内安装有检测设备,所述检测设备包括电性连接的甲烷传感器和报警器,所述甲烷传感器安装在检测空间内;所述外壳内部设置有屏障空间,所述屏障空间内设置有两个隔板且采用隔板分隔为三个水平分布的屏障单元其分别为主屏障单元一、主屏障单元二和主屏障单元三。本发明内部设置了三个主屏障单元,前期制作和固定难度较小,且成本较低,后期维护方便;主屏障物和次屏障物之间形成有检测空间,可以在检测空间内安装检测设备,以对燃气泄漏进行检测。
