Natural gas can be liquefied at normal pressure and around -162°C. The volume of liquefied natural gas is about 1 / 625 of the gaseous volume. Under normal pressure, the density of LNG is about 430-470kg / (slightly different due to different components), the ignition point is about 650°C, the calorific value is 52MMBtu (1MMBtu=2.52×108cal), and the explosion limit (volume) in air is 5%-15%. The storage of liquefied natural gas is one of the natural gas storage methods.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model proposes a protective device for natural gas storage tank transportation, including a base 1, a protective seat 2, an anti-sway structure 3 and a positioning structure 4. The protective seat 2 is arranged on the base 1, the anti-sway structure 3 is arranged on the protective seat 2, and the positioning structure 4 is arranged on the protective seat 2. The anti-sway structure 3 includes a rotation groove 5, a groove 6, a rotation axis 7, a clamping seat 8 and a support spring 9. The rotation groove 5 runs through the protective seat 2, the groove 6 is arranged at the bottom of the protective seat 2, the rotation axis 7 is fixed on the protective seat 2, the rotation axis 7 runs through the rotation groove 5 and is fixed on the wall of the protective seat 2, the clamping seat 8 is rotatably arranged on the rotation axis 7, the clamping seat 8 is arranged in an L shape and the angle is sixty degrees, the clamping seat 8 is arranged on the circumference of the protective seat 2 and is evenly arranged at sixty degrees, and one end of the support spring 9 is supported on the clamping seat 8 and the other end is supported on the bottom of the groove 6.
