Description

Technical Field

[0001] This utility model relates to the field of fire pump technology, and more specifically, to a backpack fire pump. Background Technology

[0002] When firefighters are fighting fires in areas inaccessible to fire trucks, they use small backpack fire pumps. While backpack fire pumps offer some convenience, existing models are quite heavy and cumbersome to carry, lacking suitable mobile support mechanisms. Furthermore, in environments where climbing or other mobile support mechanisms are unnecessary, disassembly and assembly are cumbersome, lacking suitable quick-assembly and disassembly mechanisms. Additionally, when not in use, the pump body is exposed to the elements for extended periods, making it susceptible to damage from external influences, and lacks adequate protective measures.
