Underwater vehicle head section packaging box suitable for being vertically placed

The invention provides an underwater vehicle head section packaging box suitable for being vertically placed, belongs to the field of packaging boxes, and particularly relates to an upper cover opening type cast aluminum alloy packaging box which can be internally filled with nitrogen, has a sealing function, a humidity display function, a grounding function and a damping function and can be stored and transported for a long time. A barrel type upper cover opening structure is adopted as a whole, an upper box body and a lower box body are in weight reduction design, thus the self weight is greatly reduced, the structure is light, and the transferring and mounting operation is convenient. An inflation valve, a pressure equalizing valve and a humidity display are designed in the device to ensure air tightness inspection and humidity display. A damping trim is made of a polyurethane damping material and is bonded in the box bodies and a box cover, so that a head section is prevented from being in direct contact
