Preferably, be equipped with the hydrogen detector No. one on No. four cavity 94 right walls, be equipped with the hydrogen detector No. two on No. three cavity 93 left walls, be equipped with the hydrogen detector No. three on No. one cavity 91 left wall, be equipped with the alarm on the 11 left side of shell.

A use method of an emergency energy charging machine for a hydrogen-oxygen fuel cell comprises the following specific steps:

firstly, when the emergency hydrogenation is required, the hydrogen tank 12 is installed, at this time, a worker places the hydrogen tank 12 in the No. six cavity 96, then the worker connects the cylinder 28 in the No. three through hole 83 in a threaded manner, at this time, the right side surface of the abutting column 30 abuts against the upper side surface of the thread block 44 of the outer ring of the No. one flow channel 41 to realize sealing, then the worker continues to rotate the cylinder 28, when the driving block 63 of the right side surface of the cylinder 28 extends into the matching groove 42, the rotating cylinder 28 drives the thread block 44 to rotate, at this time, the thread block 44 moves inwards and drives the extension plate 39 to lose the sealing effect of the sealing block 40, at this time, hydrogen in the No. five cavity 95 sequentially passes through the No. two flow channel 43, the No. one flow channel 41, the No. one rubber tube 15 and the No. one through hole 81 to enter the No. two rubber tube 16, and the hydrogen in the No. two rubber tube 16 cannot continuously circulate because the No. two rubber tube 16 is extruded by the, then, the worker needs to fix the hydrogen tank 12, at this time, the worker enables the first motor 22 to be powered on, the first motor 22 drives the first rotating shaft 23 to rotate the rack 21 when being powered on, the second rotating shaft 25 is driven to rotate by driving the second gear 26 when the rack 21 moves, the second rotating shaft 25 drives the abutting block 27 in threaded connection with the second rotating shaft to move inwards, the abutting blocks 27 in the four clamping devices 101 synchronously move inwards and clamp the hydrogen tank 12, when the feedback pressure of the pressure sensor in the abutting block 27 reaches a threshold value, the first motor 22 is powered off, and at this time, the installation and the fixing work of the hydrogen tank 12 are completed;

the second step makes the invention move to the vicinity of the new energy automobile needing hydrogenation, the first spring 14 provides the function of shock absorption during the movement of the invention, and because the first rubber tube 15 is also made of flexible materials, the shaking of the hydrogen tank 12 cannot generate rigid collision, the safety is ensured, then a worker connects the hydrogenation gun 18 to a hydrogenation port of a new energy automobile, the worker enables the second motor to be electrified, the second motor 24 enables the three upright posts 35 to rotate through driving the disc 35 when being electrified, the three upright posts 35 drive the extrusion wheel 37 connected to the three upright posts to do circular motion when rotating, the second rubber tube 16 extruded by the extrusion wheel 37 and the inner annular surface of the arc-shaped plate 38 can enable hydrogen in the second rubber tube to flow into the second through hole 82 periodically and in a controllable amount, and then the hydrogen entering the second through hole 82 can enter the hydrogenation gun 18 through the third rubber tube 19 to hydrogenate the new energy automobile.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
