Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a hydrogen energy unmanned aerial vehicle hydrogen storage cylinder fixing device. Background Art

[0002] Hydrogen energy has been widely used as a clean energy. Hydrogen energy needs to be packaged in hydrogen storage cylinders. The interior of a hydrogen energy drone needs to be fixed with hydrogen storage cylinders at designated locations.

[0003] After searching, the existing patent (Announcement No.: CN217674104U) discloses a hydrogen energy hydrogen cylinder transportation fixing device, which relates to the technical field of hydrogen cylinder transportation devices. The hydrogen energy hydrogen cylinder transportation fixing device includes a base plate, a vertical plate, a threaded rod, an upper bevel gear, a transmission rod, a lower bevel gear, a knob, a sliding hole, a lifting rod, a fixing plate, a fixing hole, an airbag, a cushion block, a hydrogen cylinder, a buffer column, a support leg, a buffer spring, a limit groove, and a limit block. The upper surface of the base plate is fixedly installed with a vertical plate. In the hydrogen energy hydrogen cylinder transportation fixing device, the shaking generated by transportation will be absorbed by the airbag, thereby avoiding collisions on the outer surface of the hydrogen cylinder. At the same time, the vibration generated by transportation will also be transmitted to the buffer spring through the support leg and cause the buffer spring to deform. The buffer spring's own elasticity can absorb the vibration generated by transportation, thereby maintaining the stability of the base plate and the hydrogen cylinder and avoiding violent shaking of the hydrogen cylinder.

[0004] However, in the implementation of the relevant technology, it was found that the above-mentioned problems exist: in the above-mentioned method, after the hydrogen cylinder is placed in the fixing hole on the fixing plate, gas is pumped into the airbag through an inflation tool to expand the airbag and tightly wrap the outer surface of the hydrogen cylinder, thereby completing the fixation of the hydrogen cylinder. When the hydrogen cylinder needs to be removed, the staff first discharges the gas in the airbag and lowers the fixing plate to the upper surface of the bottom plate. The staff needs to lift the hydrogen cylinder upwards to move it out of the fixing hole. After that, the staff needs to lift the hydrogen cylinder in a vertical direction to remove it, which makes the removal process of the hydrogen cylinder very inconvenient. Utility Model Content
