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.
