A movable column 323 is rotatably installed on the lower side of the movable support platform 322. The movable column 323 is in rolling contact with the rotating arm 316 and the driving roller 317. The circumference of the gear 314 is consistent with the distance between two adjacent movable columns 323.

[0045] The floating support module 33 includes a fixed support cylinder 331, a floating support cylinder 332 and a floating support assembly. The fixed support cylinders 331 are evenly and evenly fixedly installed on the mobile support platform 322; a floating support cylinder 332 for supporting the liquid nitrogen barrel 2 is provided on the upper side of the fixed support cylinder 331; the fixed support cylinder 331 is sleeved on the outside of the floating support cylinder 332; the floating support assembly is installed between the fixed support cylinder 331 and the floating support cylinder 332;

[0046] The floating support assembly includes a support spring 333, a slider 334 and a slide groove 335. A plurality of support springs 333 are evenly arranged on the bottom of the fixed support cylinder 331.

[0048] The mounting frame 42 is selected from commercially available mature equipment in this field.

[0049] In this embodiment, when the mobile storage mechanism 3 and the detection module 4 are working normally, the driving motor 315 drives the gear 314 to rotate. The rotation of the gear 314 drives the driving platform 313 to move in cooperation with the rack 312. The driving platform 313 moves horizontally under the limiting action of the first guide rail 311; thereby, the gear 314 rotates while moving horizontally; the gear 314 drives the rotating arm 316 to rotate while moving horizontally, thereby pushing the moving column 323 through the rotating arm 316 and the driving roller 317; the moving column 323 drives the mobile support platform 322 to move along the second guide rail 321.

The stability of the floating support cylinder 332 is ensured; the floating support cylinder 332 is floated and supported by the support spring 333; when the liquid nitrogen content in the liquid nitrogen barrel 2 is high, the liquid nitrogen barrel 2 and the liquid nitrogen in the liquid nitrogen barrel 2 press down the floating support cylinder 332, thereby pressing down the support spring 333 to compress the floating support module 33; at this time, the position of the floating support cylinder 332 and the liquid nitrogen barrel 2 on the floating support cylinder 332 is lower; thereby, the position of the mounting bracket 42 and the reflector 43 on the upper side of the liquid nitrogen barrel 2 is lower; in the initial state, the laser emitted by the laser position sensor 41 passes through the two reflectors 43 If the liquid nitrogen in the liquid nitrogen barrel 2 evaporates and causes the liquid nitrogen level to drop, the support spring 333 will reset and drive the floating support cylinder 332 and the liquid nitrogen barrel 2 to move vertically upward under the limiting action of the slider 334 and the slide groove 335, thereby driving the mounting bracket 42 and the reflective sheet 43 to move vertically upward until the laser emitted by the laser position sensor 41 contacts the reflective sheet 43 on the lower side; at this time, liquid nitrogen is replenished into the liquid nitrogen barrel 2 where the reflective sheet 43 contacts the laser of the laser position sensor 41 through the liquid supply mechanism 5 until the reflective sheet 43 on the upper side of the mounting bracket 42 contacts the laser of the laser position sensor 41.
