[0033] When in use, nitrogen is introduced through the air inlet pipe 2, and then the sealing plug 22 moves upward, and the winding assembly winds up the pull rope 10. When the pull rope 10 is wound up, the pull rope 10 rubs against the matching wheel 19, causing the matching wheel 19 to rotate, and the touch rod 20 contacts the contact 18 in the spiral groove 17, so that the marking lamp bead 8 on the top of the contact 18 is energized and lights up. After the nitrogen is introduced, the matching wheel 19 stops rotating, and the touch rod 20 contacts different contacts 18 to determine the number of rotations. When storing nitrogen, if nitrogen leaks, the sealing plug 22 moves downward, causing the matching wheel 19 to reverse, and the contact 18 contacted by the touch rod 20 changes. At this time, when the control panel 7 receives the dynamic change of the marking lamp bead 8, an alarm is generated to avoid excessive leakage of nitrogen.

[0034] The winding assembly includes a side plate 9 and a mounting box 12, wherein the mounting box 12 is welded to the outer side wall of the storage tube 5, and the inner side wall of the mounting box 12 is rotatably connected to a winding column 15, and a coil spring 11 is sleeved on the outer side wall of the winding column 15, and the two ends of the coil spring 11 are respectively in contact with the outer side wall of the winding column 15 and the inner side wall of the mounting box 12, and the other end of the pull rope 10 is wound around the outer side wall of the winding column 15, and the side plate 9 is welded to the outer side wall of the storage tube 5, and an anti-wear column 36 is rotatably connected between the outer walls on the opposite side of the side plate 9, and the anti-wear column 36 is in contact with the pull rope 10;

[0037] When the control panel 7 detects nitrogen leakage, the micro motor 13 is controlled to start driving the gear 25 to engage and rotate the ring gear 24. When the ring gear 24 rotates, the bending rod 27 moves outward under the cooperation of the matching rod 23 and the arc groove 16, and disengages from the clamping of the sealing ring 29. The sealing ring 29 slides downward. When it slides to the top of the protective cylinder 4, the sealing strip 30 cooperates with the sealing groove 31 to achieve the sealing of the outside of the storage cylinder 5, so as to avoid excessive leakage of nitrogen and the impact on the surrounding environment.

[0038] Working principle: When in use, nitrogen is introduced through the air inlet pipe 2, and then the sealing plug 22 moves upward, and the winding column 15 is driven to rotate by the winding spring 11, thereby winding the pull rope 10, and the pull rope 10 rubs against the matching wheel 19, so that the matching wheel 19 rotates, and the touch rod 20 contacts the contact 18 in the spiral groove 17, so that the marking lamp bead 8 on the top of the contact 18 is powered on and lights up. After the nitrogen is introduced, the matching wheel 19 stops rotating, and the touch rod 20 contacts different contacts 18 to determine the number of rotations. When storing nitrogen, if nitrogen leaks, the sealing plug 22 moves downward. The mating wheel 19 is reversed, and the contact point 18 contacted by the touch rod 20 is changed.

[0041] Working principle: When the sealing ring 29 slides downward, the second card plate 35 on the inner wall of the sealing ring 29 squeezes the first card plate 33. At this time, the first card plate 33 generates a reverse resistance force on the second card plate 35. The spring 32 pushes the card plate seat 34 downward, thereby making the first card plate 33 resist the second card plate 35 downward, and pressing the sealing strip 30 and the sealing groove 31 into a tight fit.
