The helicopter has high flying speed, is not limited by road traffic conditions in air flight, can fly linearly, and can effectively solve the problems. The conventional helicopter is applied to forest fires, the field environment is relatively simple, and the safety is higher by adopting a bucket fire extinguishing mode to throw the fire extinguishing agent at high altitude at one time. Different from forest fire extinguishment, the power transmission line forest fire extinguishment has the following characteristics:

1. the mountain fire points of the power transmission line are multi-sided and wide, more than 30 mountain fires of one local power transmission line can be simultaneously generated, and the fire extinguishing with multiple fire points is required;

2. the power transmission line forest fire extinguishing agent generally adopts the extinguishing agent with higher viscosity, even mixed clay, so as to avoid the increase of evaporation capacity caused by the diffusion of water agents, and the mode that selectable water pumps and extinguishing agent pumps are less and even can not be suitable for water gun fire extinguishing is adopted.

3. Need to take water and put out a fire in the field for a long time, adopt fire extinguishing agent even, open-air water and fire extinguishing agent all have certain corrosivity, and traditional helicopter fire extinguishing system arranges the power cable in the water tank in order to drive opening and shutting of fire extinguishing system, and the power and the control cable to helicopter fire extinguishing system are corrosive big, and the reliability is low, the life-span is short, and is difficult for the maintenance.
