Helicopter fire-fighting pod for forest fire prevention

Abstract

The invention belongs to the field of forest fire prevention equipment, and particularly relates to a helicopter fire-fighting pod for forest fire prevention. The helicopter fire-fighting pod comprises a lifting mechanism and a pod body, the pod body is connected with the lifting mechanism through a lifting rope, the pod body structurally comprises a square groove, two side overturning plates, a floating plate, an upper cover and a soft liner, the square groove is of a rectangular structure, the four vertical edges of the square groove are of the same height, the two side overturning plates are hinged to the two short vertical edges of the square groove correspondingly, the floating plate is made from lightweight materials with the density less than that of a fire extinguishing agent, bending parts bending inwards are arranged on the upper side edges of the side overturning plates, and the bending parts hook the upper cover to prevent the upper cover from coming out from the position between the two side overturning plates. According to the helicopter fire-fighting pod for forest fire prevention, the floating plate is arranged in the pod body, flowing of the fire extinguishing agent can be effectively controlled in the transportation process of a helicopter, the change of the center of gravity of the pod body caused by flowing of the fire extinguishing agent is avoided, thus the potential safety hazard in the flight is eliminated, and the technical requirements for a pilot are lowered.

Description

Technical field [0001] The invention belongs to the field of forest fire prevention equipment, and in particular relates to a helicopter fire pod for forest fire prevention. Background technique [0002] Forest fire prevention is an important work content in forestry management, and helicopter fire fighting is an important means of fire fighting. In the prior art, there are two main ways to extinguish fires by helicopters, but they all have drawbacks: one is to use dedicated fire-fighting helicopters. The drawback is that the purchase cost of dedicated fire-fighting helicopters is high and the utilization rate is low, so the comprehensive use cost is very high. High; the other is to use ordinary helicopters to lift and spray the fire extinguishing agent. When using this method to extinguish the fire, the pod is freely suspended under the helicopter through the wire rope. This transportation method will seriously affect the stability of the helicopter flight and slow down The fly...

AI Technical Summary

Problems solved by technology

In the prior art, there are two main methods for helicopter fire extinguishing, but both have disadvantages: one is to use a special-purpose fire-fighting helicopter. The other is to use ordinary helicopters to hoist and spray fire extinguishing agents. When using this method to extinguish the fire, the pod is freely suspended under the helicopter through wire ropes. This transportation method will seriously affect the flight stability of the helicopter and slow down At the same time, when the helicopter accelerates or decelerates, the liquid fire extinguishing agent will flow uncontrollably under the action of inertia in the pod. This flow will suddenly change the center of gravity of the pod, seriously affecting the center of gravity of the helicopter during flight. The layout of the aircraft poses a huge hidden danger to the flight safety of the aircraft and puts forward extremely high requirements on the pilot's driving skills.
