Description

Technical Field

[0001] This utility model relates to the field of fire protection, and in particular to a precise and reliable three-dimensional rotating fire extinguishing device. Background Technology

[0002] Fire prevention is the core of fire protection engineering, encompassing multiple fields such as building fire protection facilities, fire extinguishing systems, fire risk management, and fire science. Fire compartments are defined through building structural designs such as fire separation and fire separation distances. Active fire suppression systems, such as automatic sprinkler systems and gas extinguishing systems, are used to control the fire, and fire risk assessment and management are combined to reduce the probability of fire. Therefore, important fire-prone areas are equipped with automatic fire extinguishing systems. Gas extinguishing systems mainly consist of gaseous extinguishing agent storage cylinders, a drive unit, piping, and nozzles. When a fire detector detects a fire signal, the control system issues a command to deliver the gaseous extinguishing agent from the storage cylinder through the piping to the protected area, where it is sprayed from the nozzles to extinguish the fire. Foam extinguishing systems consist of foam liquid storage devices, foam proportioning devices, and foam generating devices. When a fire occurs, foam liquid and water are mixed in a specific ratio, and foam is generated by the foam generating device. The foam covers the surface of the burning material, isolating it from air and providing cooling. For example, in an oil depot fire, a foam extinguishing system can generate a large amount of foam to cover the oil surface, preventing oil vapor from mixing with air and cooling the oil surface temperature, thus achieving the effect of extinguishing the fire.

[0003] However, the traditional fire extinguishing system mentioned above has fixed nozzles and pipelines. Once a fire is detected, the entire fire extinguishing system will be activated, which will result in the entire space being extinguished when a single point catches fire. This will waste fire extinguishing gas, foam, and water, and all items in the space will be wetted by foam and water, resulting in property damage. Utility Model Content
