Helicopter fire extinguishing method by adding water system fire extinguishing agent

Abstract

The invention discloses a forest fire extinguishing method with water extinguishing agents added into a helicopter. The method comprises the steps of 1, adding the water extinguishing agents, specifically, enough fire extinguishing agents are added into a fire extinguishing agent device arranged on the helicopter before fire extinguishment; 2, adding pure water, specifically, a water containing device arranged on the helicopter is filled with the pure water before fire extinguishment; 3, extinguishing fire, specifically, a flow control mechanism adjusts the output quantity of the fire extinguishing agents and the output quantity of the pure water and the fire extinguishing agents and the pure water are sprayed to the forest fire after being mixed; 4, executing the step 5 and continuously extinguishing the fire if the forest fire is not extinguished, and otherwise completing the fire extinguishment; and 5, supplementing the water, specifically, the helicopter is supplemented with the water after landing or flies to a qualified water source surface for drawing water. According to the method, the fire extinguishing agents can be directly added into the water containing device, and therefore the fire extinguishment efficiency of the existing fire extinguishment modes of the helicopter can be improved, the flight cost can be lowered, the forest fire extinguishing technology adopting the helicopter can be popularized in prevention and control of the forest fire of power grids, and a powerful scientific and technological means can be provided for prevention and control of the forest fire of the power grids.

Description

technical field [0001] The invention belongs to the technical field of disaster prevention and reduction for power transmission lines in electric power systems, and in particular relates to a method for extinguishing mountain fires by helicopters by adding water-based fire extinguishing agents. Background technique [0002] Since the 1950s and 1960s in the world, helicopter fire extinguishing technology has been applied to forest fire fighting. The characteristics of using helicopters to fight forest fires are strong mobility, high efficiency, and convenient water intake and replenishment. Especially for some large-scale forest fires, when ground firefighting equipment cannot reach the scene or carry out fire-fighting operations near the fire scene, helicopter fire-fighting is almost the only feasible fire-fighting measure. However, the biggest disadvantage of using helicopters to put out fires is the high cost of flying the planes. Usually, the cost of flying a single plan...

AI Technical Summary

Problems solved by technology

However, the biggest disadvantage of using helicopters to put out fires is the high cost of flying the planes. Usually, the cost of flying a single plane can reach tens of thousands to hundreds of thousands of yuan per hour.

[0003] Compared with forest fires, although small-area wildfires near transmission lines are less harmful to forest resources, they seriously endanger the safe and stable operation of transmission lines and affect the reliability of power supply of large power grids. Its fire fighting is a social problem

If the existing helicopter is used to carry pure water to fight wildfires, it is bound to achieve a good fire extinguishing effect, but its high flight cost makes fire fighting economical, so it is rarely used in power grid wildfire fighting.
