Efficient fine-water-mist fire extinguishing aviation bomb used for forest surface fire

Abstract

The invention provides an efficient fine-water-mist fire extinguishing aviation bomb used for forest surface fire. The efficient fine-water-mist fire extinguishing aviation bomb comprises a bomb body (2) and a bomb tail (6). The bomb body (2) is in threaded connection with the bomb tail (6). The bomb body (2) comprises a gas generator (1) and a water system fire extinguishing containing part (4), and the gas generator (1) and the water system fire extinguishing containing part (4) are both arranged in the bomb body (2). The gas generator (1) is in threaded connection with the head end of the bomb body (2). The bomb tail (6) is provided with a fine-water-mist spray head assembly (5) comprising a liquid guide pipe (3) and a spray head (12) provided with a pressure valve (11). One end of the liquid guide pipe (3) is connected with the spray head. The opening end of the liquid guide pipe (3) is arranged at the head end of the bomb body. According to the efficient fine-water-mist fire extinguishing aviation bomb used for the forest surface fire, a helicopter or aircraft release mode is adopted, so that a large number of the fire extinguishing aviation bombs are carried without the limitation of release altitude and fall in target fire areas accurately.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a high-efficiency fine water mist fire extinguishing aerial bomb used for forest surface fires. Background technique [0002] There are more than 220,000 forest fires in the world every year, and the burned forest area exceeds 6.4 million hectares, accounting for more than 0.23% of the world's forest coverage. my country's forest area is 120 million hectares, and the forest area engulfed by fire every year is 1.1 million hectares, accounting for 0.8% to 0.9% of the national forest area. Therefore, forest fire fighting has always been the national disaster prevention and mitigation work. One of the main content. [0003] Forest fires are usually divided into three types: surface fires, tree crown fires, and underground fires according to their burning objects and burning parts. Surface fire is the most common forest fire, which accounts for 94% of all forest fires. Surface fires ca...

Problems solved by technology

[0004] For extinguishing forest surface fires, practice shows that Fengshui fire extinguishers have the longest fire extinguishing time, and the water spray volume is small, mainly relying on wind to disperse the fire; water pump spray fire extinguishing is the most primitive fire extinguishing method, which takes the shortest time and has the best fire extinguishing effect. It is good, but the equipment is bulky, and it is difficult to transport and replenish water. This is also a problem that is difficult to solve in forest firefighting. Compared with water pumps, water guns save water, but the water flow is small, and the fire extinguishing time is long. Operators are manual and easy to fatigue. Can be used to fight small-scale fires, not suitable for fighting forest fires

When using airplane or helicopter to lift water or dry powder to extinguish the fire, it is difficult for the fire extinguishing agent to fall on the ground due to the high temperature air waves of the crown fire, and the cost of fire extinguishing is extremely high
