The invention discloses a helicopter lifting bucket capable of adding water extinguishing agent series. The helicopter lifting bucket comprises a lifting bucket wall, a base provided with a plurality of liquid exhaust holes and a lifting rope, wherein a bottom valve for starting and closing the liquid exhaust holes is arranged above the base, and is controlled to open and close by a pneumatic actuator; the inner side of the lifting bucket wall is tightly attached to an annular fire extinguishing agent bag which is internally sleeved by an air bag; the maximal volume of the air bag is equivalent to the volume of the fire extinguishing agent bag which is provided with a fire extinguishing agent bag liquid injection valve and a plurality of unidirectional valves; the air bag is provided with an air bag air charge valve and an air bag air discharge valve; the air bag air charge valve and the pneumatic actuator are both communicated with an air pump installed on a helicopter via air pipes; the air pump is controlled by a controller installed on the helicopter. The helicopter lifting bucket can obviously enhance the fire extinguishing efficiency of the lifting bucket of the helicopter, can reduce the flight cost of the helicopter, accelerate the fire extinguishing speed, can obviously reduce the loss of a power grid due to forest fire, and has the advantages of simple and compact structure, good fire extinguishing effect, high efficiency, wide application range and the like.
