Explosion soil covering and carbon dioxide releasing combined dual fire extinguishing system and method

Abstract

The invention provides an explosion soil covering and carbon dioxide releasing combined dual fire extinguishing system and method. The system comprises an unmanned aerial vehicle group, a control platform, an RTK positioning module, a 5G communication module, a fire extinguishing bomb and a dispenser, wherein the RTK positioning module and the 5G communication module are carried in an unmanned aerial vehicle body, the dispenser is located below the unmanned aerial vehicle body and connected with a power source and the 5G communication module in the unmanned aerial vehicle body, and the fire extinguishing bomb is carried in the dispenser. Compared with the prior art, the system has the beneficial effects that the unmanned aerial vehicle group is controlled to hang the carbon dioxide fire extinguishing bomb when a fire disaster occurs in forests and grasslands, fire spreading and development are prevented and controlled by exploding covering soil and releasing carbon dioxide which can doubly isolate an oxidizing agent and combustible materials, so that the fire can be controlled. The method has the advantages of being efficient, safe, easy to implement and the like, the problem of secondary disasters caused by explosion fire extinguishing is avoided, a reliable scheme is provided for forest and grassland fire-fighting in China, and the purposes of reducing resource consumption and improving fire extinguishing efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of forest and prairie fire protection, and relates to the technology of unmanned aerial vehicle bombing and explosion fire extinguishing, in particular to a dual fire extinguishing system and method of explosive covering soil and releasing carbon dioxide. Background technique [0002] At present, there are mainly four kinds of forest and grassland fire extinguishing technologies at home and abroad, namely mechanical ground fire extinguishing, wind fire extinguishing, aviation fire extinguishing and explosion fire extinguishing. Mechanical ground fire extinguishing and wind fire extinguishing are not only inefficient and time-consuming, but also seriously endanger the lives of firefighters. The advantage of aviation fire extinguishing technology is that it is highly maneuverable and not restricted by the terrain. The disadvantage is that in order to ensure the safety of the aircraft, the fire extinguishing age...

Problems solved by technology

[0002] At present, there are mainly four kinds of forest and grassland fire extinguishing technologies at home and abroad, namely mechanical ground fire extinguishing, wind fire extinguishing, aviation fire extinguishing and explosion fire extinguishing. Mechanical ground fire extinguishing and wind fire extinguishing are not only inefficient and time-consuming, but also seriously endanger the lives of firefighters. The advantage of aviation fire extinguishing technology is that it is highly maneuverable and not restricted by the terrain. The disadvantage is that in order to ensure the safety of the aircraft, the fire extinguishing agent needs to be sprinkled at a certain height, which leads to the fact that the fire extinguishing agent that actually works is greatly reduced due to wind and evaporation, and the cost of aviation fire extinguishing is expensive. , sometimes due to distance limitations, it is inconvenient to replenish fire extinguishing agents

[0003] With the maturity of UAV technology, the use of UAVs to throw fire extinguishing bombs to explode fires has the advantages of high efficiency, low cost, and no casualties. However, the existing fire extinguishing bombs only have dry powder fire extinguishing bombs and foam fire extinguishing bombs. The adhesion of the former The latter is difficult to last because of the foam itself. When the fire is large, the isolation zone formed by this method lasts for a short time, and it is difficult to achieve the purpose of fire extinguishing. Therefore, a carbon dioxide fire extinguishing bomb mounted on a drone is required to explode and release Carbon dioxide double fire extinguishing technology inherits the advantages of aviation fire extinguishing and explosion fire extinguishing technology at the same time. It can not only solve the problem of complex terrain and high danger in forest and grassland fire areas, but also has the characteristics of high efficiency, safety and easy implementation, and also avoids explosion fire extinguishing. The problem of secondary disasters
