Description

Technical Field

[0001] The utility model relates to the field of forest fire rescue, in particular to a forestry fire emergency foam fire extinguishing and rescue device. Background Art

[0002] As we all know, since the occurrence of forest fires requires the presence of combustibles, oxygen and fire sources, the fire-fighting measures taken should be able to isolate the combustibles, or reduce the amount of combustible vapor to below the ignition limit; isolate the air, or make the oxygen content in the air lower than 14-18%; and the temperature of the combustibles should be reduced to below the ignition point. According to this principle, various forest fire-fighting methods can be summarized as: 1. Suffocation method, such as covering with soil, spraying fire extinguishing agents and beating, which can isolate the air required for combustion and achieve the purpose of fire extinguishing, and is suitable for the initial stage of fire; 2. Cooling method, that is, covering the burning combustibles with wet soil or sprinkling water, so that the temperature of the burning combustibles drops below the ignition point and extinguishes the fire.

[0003] Existing forest fire emergency foam fire extinguishing and rescue devices are generally composed of a sprinkler, a water pump, a foam box, a water tank and a vehicle body. The staff starts the water pump to rescue the forest fire.

[0004] Although the existing forestry fire emergency foam fire extinguishing and rescue device can be used to rescue forest fires, the fire extinguishing efficiency is greatly reduced due to the uneven mixing of foam and water, resulting in economic losses. In addition, since the nozzle needs to be held by the staff for flexible fire extinguishing, it is easy to pose a threat to the personal safety of the staff. Therefore, a forestry fire emergency foam fire extinguishing and rescue device is needed. Utility Model Content
