Hydrogen storage device for unmanned aerial vehicle

Abstract

The invention discloses a hydrogen storage device for an unmanned aerial vehicle. The hydrogen storage device comprises an unmanned aerial vehicle body; a hydrogen energy storage mechanism is arrangedat the lower end of the unmanned aerial vehicle body; a hydrogen cylinder switching mechanism is arranged on one side of the hydrogen energy storage mechanism; and a hydrogen cylinder butt joint mechanism is arranged on one side of the hydrogen cylinder switching mechanism. According to the hydrogen storage device of the invention, a plurality of hydrogen cylinders can be separated under the action of the hydrogen energy storage mechanism, so that grave threats to the unmanned aerial vehicle due to the leakage and burst of the hydrogen cylinders can be prevented, the safety of fuel is effectively improved; the hydrogen cylinders can provide stable energy for an engine under the action of the hydrogen cylinder switching mechanism, the phenomenon of gas supply interruption is effectively prevented, and stable flight of the unmanned aerial vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydrogen kinetic energy unmanned aerial vehicles, and more specifically, relates to a hydrogen storage device for unmanned aerial vehicles. Background technique [0002] Hydrogen is a colorless gas. Burning one gram of hydrogen can release 142 kilojoules of heat, which is three times the calorific value of gasoline. The product of its combustion is water, without ash and waste gas, and will not pollute the environment. Hydrogen The weight of hydrogen is very light, it is much lighter than gasoline, natural gas, and kerosene, so it is more inconvenient to carry and transport, but hydrogen as a fuel is still considered to be the most ideal energy source in the 21st century. The outstanding characteristics of hydrogen fuel as an energy source are No pollution, high efficiency, recyclable. [0003] At present, hydrogen is also the most ideal energy source for drones. Gaseous hydrogen is compressed and stored...

Problems solved by technology

[0003] At present, hydrogen is also the most ideal energy source for drones. Gaseous hydrogen is compressed and stored in hydrogen cylinders. Generally, there is only one large hydrogen cylinder, but its safety factor is low. Once the hydrogen cylinder leaks or bursts, it will It poses a greater threat to the flight of drones; and the larger hydrogen cylinders are cumbersome and inconvenient for manual inflation or installation; in order to ensure the endurance of hydrogen kinetic energy drones, the device is equipped with multiple smaller hydrogen cylinders, When a hydrogen cylinder is almost used up, it is necessary to switch to the next hydrogen cylinder. During this operation, the gas supply is likely to be interrupted, resulting in unstable working conditions of the hydrogen kinetic energy engine.
