Hydrogen leakage detection equipment for hydrogen transporting long tube trailer

The invention relates to the technical field of hydrogen detection, in particular to hydrogen leakage detection equipment for a hydrogen transporting long tube trailer. The technical problems that through vibration generated by different road surfaces, aging generated by long-time use, vehicle collision and the like, a hydrogen storage bottle of the long-tube trailer may leak, even combustion or explosion can be caused, so that life safety of passersby and drivers is threatened, meanwhile, when leaked hydrogen burns, flames cannot be extinguished in time, and the safety of the long-tube trailer is affected are solved. And therefore, equipment around the flame is burnt by the flame, and great economic loss is caused. According to the technical scheme, the hydrogen leakage detection equipment for the hydrogen transporting long tube trailer comprises a bearing box, a movable door and the like; the upper side of the bearing box is movably connected with a movable door. By observing the alarm sent by the hydrogen
