Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a port fire extinguishing auxiliary device. Background Technology

[0002] A port is a transportation hub located along the coast of the sea, river, lake, or reservoir, equipped with water-land intermodal transport facilities and conditions to allow ships to enter, exit, and berth safely. It is also a gathering point and hub for water and land transportation, a distribution center for industrial and agricultural products and foreign trade import and export goods, and a place for ships to berth, load and unload cargo, embark and disembark passengers, and replenish supplies.

[0003] Port fire safety is of paramount importance, affecting the safety of personnel and property, and indirectly impacting economic operations and global trade. When cargo is stored or transported in high-temperature environments, poor ventilation can prevent heat dissipation, increasing the risk of spontaneous combustion. While port water sources are used for firefighting, existing port firefighting auxiliary devices struggle to effectively utilize water to suppress fires, and their limited coverage area hinders fire suppression. Therefore, we propose a port firefighting auxiliary device to address these issues. Utility Model Content
