Technical Field
The utility model relates to the technical field of fire fighting equipment, in particular to a forest fire prevention helmet with an oxygen respirator.
Background
In recent years, as China continuously promotes the national landscaping on a large scale, the total quantity of forest resources is rapidly increased, the ecological environment is improved day by day, the forest fire prevention battle line is longer and longer, regional fire prevention is changed into national fire prevention, and seasonal fire prevention is changed into comprehensive fire prevention. Although China continuously perfects the forest fire prevention system with Chinese characteristics, the forest fire prevention situation in China is still very severe. Recently, in parts of domestic areas, forest fires frequently occur, a large amount of manpower, financial resources and material resources are invested, the ecological environment is irreversibly damaged, the development of regional economy and afforestation results are seriously affected, and in addition, the dense smoke pavement is frequently damaged and casualties are frequently caused due to wind direction mutation in the forest fire suppression process.
At present, in the process of putting out a forest fire, a forest fire prevention team member has few emergency means for dealing with dense smoke pavement caused by sudden change of wind direction, and in the process of putting out a forest fire, protective equipment such as an oxygen bottle, an oxygen tank and the like is inconvenient to carry and cannot achieve the purpose of emergency, so that the research of an effective emergency protective measure which is convenient to carry and use is urgent.
Through published patent searches, the following comparison documents were found:
CN202020412742.6, discloses a multifunctional fire-fighting helmet, which comprises a helmet shell; the top end of the outer wall of one face, opposite to the face, of the helmet shell is provided with an emergency illuminating lamp, an air sampling hole is formed in the helmet shell on one side of the emergency illuminating lamp, the air sampling hole is communicated with an air quality detector through a sampling hose, and the air quality detector is electrically connected with an alarm device; a built-in respirator is arranged in the helmet shell below the emergency illuminating lamp, a control valve is arranged on the respirator, and the respirator is communicated with an external oxygen supply device through an oxygen supply pipe; a first high-definition camera used for collecting the fire rescue situation in front of a fire fighter in real time is installed below the emergency lighting lamp, and a second high-definition camera used for collecting the fire rescue situation on the rear side of the fire fighter in real time is arranged on the rear side of the helmet shell. The multifunctional fire-fighting robot is simple in structure and multifunctional, effectively guarantees personal safety of fire fighters, reduces potential safety hazards and improves rescue efficiency.
Through the analysis, above-mentioned fire helmet still does not possess oxygen storage function, still need wear the oxygen cylinder during its use, can't judge and adjust the oxygen suppliment on-off state by the fire fighter by oneself according to wind direction and condition of a fire etc. consequently does not influence the novelty of this application.
