The invention relates to the technical field of forest fire control, in particular to a helicopter fire extinguishing device. The helicopter fire extinguishing device comprises a bucket, a solid powder conveying system, a fire extinguishing agent dissolving container and a water pumping system, wherein the bucket is suspended on a helicopter; the fire extinguishing agent dissolving container surrounds the outer wall of the bucket; the solid powder conveying system is used for conveying fire extinguishing agent raw material solid powder in a helicopter inner cabin into the fire extinguishing agent dissolving container; the water pumping system is used for pumping water in the bucket into the fire extinguishing agent dissolving container; and the fire extinguishing agent dissolving container is used for dissolving the fire extinguishing agent raw material solid powder to form a liquid fire extinguishing agent and conveying the liquid fire extinguishing agent into the bucket. According to the helicopter fire extinguishing device provided by the invention, the fire extinguishing agent dissolving container is arranged around the outer wall of the bucket, and an aqueous solution and the liquid fire extinguishing agent do not need to flow through the helicopter inner cabin, so that the safety risk caused by leakage of the aqueous solution or the liquid fire extinguishing agent is avoided; and the gravity center distribution of the helicopter is not changed, so that the flight safety and the flight stability of the helicopter are ensured.
本发明涉及山火防治技术领域,尤其涉及一种直升机灭火装置。该直升机灭火装置,包括吊桶、固体粉剂传输系统、灭火剂溶解容器和泵水系统,吊桶悬挂在直升机上,灭火剂溶解容器环绕在吊桶的桶外壁;固体粉剂传输系统用于将直升机内舱内的灭火剂原材料固体粉剂输送至灭火剂溶解容器内;泵水系统用于将吊桶内的水泵入灭火剂溶解容器内;灭火剂溶解容器用于溶解灭火剂原材料固体粉剂以形成液态灭火剂,并将液态灭火剂输送至吊桶内。本发明提供的直升机灭火装置,灭火剂溶解容器环绕吊桶的桶外壁设置,水剂及液态灭火剂无需流经直升机内舱,避免水剂或液态灭火剂泄漏带来安全风险,且不改变直升机的重心分布,确保直升机飞行的安全性与平稳性。
