[0081] It should be noted that:

[0082] In this application, two first telescopic rods 13 and two second telescopic rods 14 are respectively provided. The first telescopic rods 13 and the second telescopic rods 14 are arranged at intervals. The connection line of the two first telescopic rods 13 and the connection line of the two second telescopic rods 14 are in a cross state. The first telescopic rods 13 and the second telescopic rods 14 are respectively hinged to the first seat body and rotate vertically around the first seat body. Thus, when used as a handling handle, the other ends of the first telescopic rods 13 and the second telescopic rods 14 are respectively connected to the second seat body located on the same helium storage tank 1; when in transportation or storage, the other ends of the first telescopic rods 13 and the second telescopic rods 14 are respectively connected to the corresponding places on the second seat bodies of adjacent helium storage tanks. When shaking occurs during transportation, the connection of the first telescopic rods 13 and the second telescopic rods 14 serves as the second buffer part of adjacent helium storage tanks 1, avoiding direct collision between the two tanks;

[0083] In this application, the mutual connection of the first seat bodies in two adjacent helium storage tanks 1 is realized through a third connecting member 16 and a connecting cavity 15. The third connecting member 16 and the connecting cavity 15 are circumferentially arranged at intervals on the outside of the first seat body. The third connecting member 16 and the connecting cavity 15 are arranged at intervals and are respectively located directly below the first telescopic rods 13 and the second telescopic rods 14. One end of the third connecting member 16 is fixedly connected to the first seat body, and the other end of the third connecting member 16 is correspondingly inserted into the connecting cavity 15 of the adjacent helium storage tank 1, forming the first buffer part of the adjacent helium storage tanks 1. When shaking occurs during transportation, direct collision between the two tanks is avoided;

[0084] In this application, the third connecting member 16 can also be other elastic members. In an embodiment of this application, the third connecting member 16 includes a spring and a slider. The two ends of the spring are respectively connected to the first seat body and the slider. The slider is inserted into the connecting cavity 15, and a protective sleeve is arranged outside the spring;

[0085] In an embodiment of this application, the connection between the first telescopic rods 13 and the second telescopic rods 14 and the second seat body is realized through a fourth connecting member 17 and a sixth connecting member 8. In an embodiment of the present invention, the sixth connecting member 8 is a connecting shaft, and the fourth connecting member 17 is in the shape of a hook; the sixth connecting member 8 is arranged circumferentially along the second seat body, is respectively located directly above the first telescopic rods 13 and the second telescopic rods 14, and is fixedly connected to the second seat body; the fourth connecting member 17 is respectively rotatably connected to the ends of the first telescopic rods 13 and the second telescopic rods 14, and the fourth connecting member 17 can respectively rotate around the axial and radial directions of the first telescopic rods 13 and the second telescopic rods 14;

[0086] In an embodiment of the present application, the hinged connection between the first telescopic rod 13 and the second telescopic rod 14 is achieved through a connecting column 18 and a fifth connecting member 11. The axes of the connecting column 18 and the fifth connecting member 11 are parallel to each other. The connecting column 18 and the fifth connecting member 11 are respectively arranged at intervals on the same side of the first telescopic rod 13 and the second telescopic rod 14 and are on the same horizontal line. The connecting column 18 is perpendicular to the first telescopic rod 13 and the second telescopic rod 14. One end of the connecting column 18 is fixedly connected to the first telescopic rod 13 or the second telescopic rod 14; one end of the fifth connecting member 11 is correspondingly rotatably connected to the second telescopic rod 14 or the first telescopic rod 13, and a circular connecting hole 12 is provided at the other end of the fifth connecting member 11. The circular connecting hole 12 is correspondingly rotatably connected to the connecting column 18;

[0087] In the present application, the tank mouth protection assembly 4 includes an inner shell 5, an elastic layer 6, and a flame retardant layer 7 that are hermetically connected in sequence from the inside to the outside;

[0088] In an embodiment of the present application, the tank mouth protection assembly 4 is hermetically connected to the top of the second seat body through a sealing ring. The second seat body and the helium storage tank 1 are also hermetically connected through a sealing ring, so that the tank mouth of the helium storage tank 1 is in a sealed space. Under normal circumstances, the elastic layer 6 does not contact the pressure sensor 10. When helium leaks, the leaked helium contacts the elastic layer 6 through the air holes on the inner shell 5. After the elastic layer 6 is inflated, it will expand and approach the flame retardant layer 7, resulting in touching the pressure sensor 10. After the pressure sensor 10 senses it, it sends this information to the controller. When the controller receives the signal, it sends an alarm command to indicate that helium has leaked.

[0089] In the controller, the pressure sensors 10 in each tank mouth protection assembly 4 are numbered respectively. After a leak occurs, the specific leaking helium storage tank 1 can be quickly found, and the loss can be reduced to the minimum;

[0090] The inner shell 5 is provided to prevent the elastic layer from being damaged by contacting the outside;

[0091] While indirectly detecting whether helium leaks through the elastic layer 6, the leaked helium is collected in the tank mouth protection assembly 4 to avoid unnecessary losses.

[0092] It should be noted that during the transportation of helium, the gas cylinders filled with helium shall not be close to the fire source, shall not be exposed to sunlight, shall not be impacted, and the helium cylinders shall be stored upright. Moreover, the temperature of liquid helium is -268.9°C, which can cause severe frostbite when coming into contact with the skin. Therefore, in this application, a transportation device is provided to prevent the self-standing helium storage tanks from colliding with each other. Additionally, the first telescopic rod 13 and the second telescopic rod 14 can be used as handles during handling to avoid direct contact with the helium storage tanks. Meanwhile, a tank mouth protection component 4 is provided to prevent open flames and promptly detect whether there is gas leakage and identify the leaking storage tank in a timely manner, thereby reducing losses.

[0093] The helium tank transportation device involved in this application can also be applied to similar gases that prevent collision and leakage.

[0094] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
