Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to an underground fire hydrant for fire protection engineering. Background Art

[0002] Firefighting is a general term for preventing and resolving man-made, natural, and accidental disasters encountered in people's lives, work, and studies. It primarily encompasses fire scene rescue, the preservation of important facilities and equipment, cultural relics, the protection and rescue of valuable property, and fire extinguishing. Its purpose is to minimize the damage caused by fires, reducing casualties and property losses. In times of war, firefighting efforts are under the unified command of civil air defense headquarters at all levels, with professional firefighting forces as the backbone. Firefighting efforts are mobilized from professional firefighting brigades in enterprises, institutions, and townships, volunteer teams, and the general public. Firefighting operations primarily include: determining the extent of the fire and damage; understanding the terrain and wind direction at the fire scene; the structure and entrances and exits of the burning building; and the location of trapped individuals. Firefighting operations are conducted on the spot, organizing forces to rapidly respond to the fire scene; selecting extinguishing agents and equipment based on the nature of the fire; and employing appropriate firefighting tactics tailored to the fire scene. Key methods include preventing fire, establishing firebreaks, blocking fire routes, extinguishing residual fire, and securing the fire scene. Trapped individuals must be rescued promptly, and the injured must be transferred and evacuated. Dangerous items near the fire scene must be promptly removed or isolated to prevent secondary disasters. Firefighting uses water and chemical extinguishing agents, utilizing fire trucks, fire extinguishers, motorized water pumps, and other equipment. Adhering to the principles of prioritizing people over materials, controlling fires before extinguishing them, and ensuring that key areas are addressed, fire hydrants are used when fire hoses require water for firefighting operations, as society evolves.
