The invention discloses an unmanned helicopter fuel filling and pumpback device which is characterized by comprising a compressed air source, a fuel filling system and a fuel pumpback system, whereinthe fuel filling system utilizes a pneumatic fuel pump to fill fuel to the fuel filler of an unmanned helicopter; the fuel pumpback system utilizes another pneumatic fuel pump to pump residual fuel inan unmanned helicopter fuel tank in a waste fuel collecting box; and the two compressed air output ends of the compressed air source are used for driving the pneumatic fuel pumps of the fuel fillingsystem and the fuel pumpback system. The unmanned helicopter fuel filling and pumpback device has the following advantages: the fuel filling and pumpback efficiency of the unmanned helicopter can be effectively improved and the unfolding and folding time of the unmanned helicopter is greatly shortened. The unmanned helicopter fuel filling and pumpback device adopts the compressed air as the powersource of the fuel pump to improve the operating safety; and a fuel medium flows in a sealed pipeline and a closed container, so that fuel volatilization is avoided, and possible fuel pollution is also avoided.
一种无人直升机燃油加注及回抽装置,其特征在于,包括压缩空气源、燃油加注系统和燃油回抽系统,该燃油加注系统利用气动燃油泵为无人机加油口加注燃油;该燃油回抽系统利用另一气动燃油泵将无人直升机燃油箱中残余的燃油抽入废油收集箱;该压缩空气源的两个压缩空气输出端分别用于驱动燃油加注系统和燃油回抽系统的气动燃油泵。本发明的优点是:能够有效提高无人直升机燃油加注、回抽的工作效率,大幅缩短无人直升机展开、撤收时间。装置采用压缩空气作为燃油泵的动力源,提高了操作的安全性。燃油介质在封闭管道和密闭容器中流动,避免了燃油的挥发,同时也避免了可能出现的燃油污染。
