[0015] Please refer to Figures 1 to 4 ;

[0016] The present embodiment provides a natural gas storage tank, comprising a tank body 1 for storing natural gas and a plurality of rollable universal balls 3 embedded in the bottom thereof, a rotatable protective support 2 is sleeved on the outer side of the bottom of the tank body 1, an inner guide rod 21 of the protective support 2 is slidably embedded in a track guide groove 11 of the tank body 1, and the protective support 2 can slide up and down under the tank body 1 when rotating.

[0017] Preferably, the bottom surface of the bottom support frame of the tank body 1 is provided with a plurality of spherical snap-fits 12 distributed in a circular array, and a reducing step with a plurality of track guide grooves 11 distributed in a circular array is provided below the side wall of the main body of the tank body 1, and the track guide groove 11 is a Z-shaped guide groove composed of a high horizontal groove, a counterclockwise downward inclined groove and a low horizontal groove.

[0018] In a specific embodiment, when the inner guide rod 21 of the protective support 2 is located in the high horizontal slot area of ​​the track guide groove 11, the bottom surface of the protective support 2 is higher than the bottom surface of the bottom support frame of the tank body 1, and the universal ball 3 embedded in the bottom of the tank body 1 is in contact with the ground, and the tank body 1 can be manually dragged to slide on the bottom surface. When the tank body 1 needs to be fixed, it is only necessary to rotate the protective support 2 so that the inner guide rod 21 of the protective support 2 slides along the track guide groove 11 to its low horizontal slot area.
