Description

Fire-fighting rescue container

Technical Field

The invention mainly relates to the technical field of fire fighting, in particular to a fire-fighting rescue container.

Background

Along with the development of the world economy, the number of urban high-rise and super high-rise buildings is increasing, and once a fire disaster happens to a high-rise building with dozens of meters or even hundreds of meters, the fire-fighting problem can be met. At present traditional fire-fighting equipment such as high-pressure squirt, fire control aerial ladder, high altitude unmanned aerial vehicle all have as follows not enoughly:

(1) the traditional high-pressure water gun is difficult to reach more than 80 meters for fire extinguishing and fire rescue due to the water pressure, the structural weight of the aerial ladder and other reasons, and the existing aerial ladder fire truck is limited by the smooth degree of the area and the street, the fire fighting truck cannot arrive at a fire scene in the first time under many conditions; moreover, fire fighting is mainly carried out by firemen who are directly close to the fire scene, so that high danger is generated and unnecessary casualties are even caused sometimes;

(2) in the face of high-rise fire fighting, a plurality of fire trucks are sometimes required to perform combined operation, the preparation time is long, aerial ladders are adopted to perform high-rise rescue, and the aerial ladders are unfolded to have a slow process, so that the rescue response is slow;

(3) for the high-altitude unmanned aerial vehicle, in view of the performance parameters of the current battery, the unmanned aerial vehicle carries the load and the self weight required by fire extinguishment, the operation time length is limited, the load of fire extinguishment is less, the air operation time is short, and the air and the ground need to be reciprocated for many times; if the carried load is more, the air operation time is short, so the fire rescue unmanned aerial vehicle powered by the battery cannot carry out high-rise fire rescue operation for a long time under a large load, and the precious time of fire rescue is delayed;

(4) in the face of complex fire rescue situations, the traditional fire fighting mode is difficult to meet the diversified and configurable fire fighting requirements of window breaking, large-flow water spraying, dry powder spraying, foam spraying and the like;

(5) due to the limitation of the operation height, the traditional fire fighting means is difficult to provide emergency rescue equipment (such as gas masks, fire blankets, strong light flashlights, interphones and the like) for people trapped at high floors and in urgent need of rescue;

(6) the single-machine operation of the existing fire-fighting unmanned aerial vehicle can complete the fire-fighting operations such as dry powder spraying fire extinguishing, water spraying and the like, and the function of a fire-fighting rescue system is not fully established.

At present, the technology of adopting the mooring unmanned aerial vehicle to carry out fire fighting is adopted, but because the fire fighting equipment is fixed on a fire fighting vehicle, the appropriate fire fighting equipment can not be selected according to the actual situation on site, so that the application scene is single, and the arrangement of the fire fighting equipment is messy, and the maintenance and management of the fire fighting equipment are inconvenient.
