Abstract

The invention discloses a retractable light self-suction aviation fire extinguishing device and a use method thereof. The device comprises a fire extinguishing agent adding device, a light telescopic water tank and a water suction device connected to the light telescopic water tank, wherein the light telescopic water tank comprises a light telescopic water tank fixing frame arranged at the lower portion of a cabin of a helicopter, a foldable and retractable soft water bag and a throwing device arranged at the bottom of the soft water bag, the water suction device comprises a water suction pipe capable of extending downwards, when water is not taken, the light telescopic water tank and the throwing device are folded and retracted in the light telescopic water tank fixing frame, when water is added, the water suction device sucks water from the lower portion into the light telescopic water tank by means of the water suction pipe so as to enable the light telescopic water tank to stretch downwards, and in a flying and water storage state, the light telescopic water tank and the throwing device are suspended in air after being stretched. According to the device, the water tank can be retracted when no water is stored, so that a height is very small, rising and falling of the aviation fire extinguishing device are not affected, and an application range is wider.

Description

technical field [0001] The invention relates to the technical field of mountain fire prevention and control, in particular to a shrinkable light-weight self-priming aviation fire extinguishing device and its use method. Background technique [0002] The use of helicopters to extinguish fires is an important way to extinguish forest fires. Helicopters fly fast, and the air flight is not restricted by road traffic conditions, so it can carry out fire extinguishing in a more timely manner. However, helicopters often need to carry water and fire extinguishing agents to improve fire extinguishing efficiency and prevent the resurgence of wildfires, so that large-scale wildfires can be effectively extinguished. [0003] The commonly used helicopter fire extinguishing devices are mainly buckets and belly water tank fire extinguishing devices, which have played an effective role in the rapid fire extinguishing of helicopters. The buckets are connected by flexible slings, and the swi...
