BACKGROUND

[0002] In the prior art, such as CN202411674665.0, a full-automatic device for preventing fire spread of new energy vehicles on roll-on / roll-off ships is provided: the device pushes the fireproof cloth to form a closed vehicle cover through a hydraulic support, which belongs to passive physical isolation, relies on a single mechanical structure and lacks intelligent spraying and hierarchical response mechanism, and is difficult to meet the complex needs of different stages of thermal runaway.

[0003] In the prior art, such as CN202211420060.X, a vehicle roll-on / roll-off ship cargo hold safety hazard early warning system and a use method thereof are provided: the system focuses on cargo hold temperature field early warning and only realizes early monitoring function, does not involve three-dimensional protection, active cooling and equipment linkage disposal after thermal runaway, and lacks a complete emergency response closed loop.

[0004] In the prior art, such as CN202311811198.7, a safety fire extinguishing system for vehicle sea transportation and a method thereof are provided: the system proposes a burning vehicle throwing device and a fixed fire extinguishing cabin, which belongs to an end disposal means and does not construct a whole-process protection system of “prevention - inhibition - blockage”, and the throwing operation has the risk of ship balance and environmental limitation.

[0005] In the prior art, such as CN202410703462.3, a safety protection system based on new energy vehicle roll-on / roll-off ships is provided: the system realizes local heat insulation and fire extinguishing through a hanging type protection organ case, and the device layout is fixed and the function is single, lacking three-dimensional spraying coverage for the chassis and the top and heat radiation blockage design for adjacent vehicles, and the system cannot form a multi-level protection network.

[0006] In the prior art, such as IMO MSC.493 (99 “Lithium Battery Transportation Safety Guidelines”), only principle suggestions are provided without specific technical solutions. In the prior art, such as UL9540A “Energy Storage System Fire Test Standard”, the standard is for fixed energy storage and is not applicable to mobile transportation scenarios.

Existing technologies still have shortcomings: land-based solutions (such as fixed sprinklers) are not suitable for ship swaying or multi-deck environments; traditional insulation materials (such as ordinary fireproof cloth) have insufficient temperature resistance and cannot block heat radiation for long periods; and there is a lack of a comprehensive "monitoring-early warning-response" process, relying on manual judgment leading to delays and other technical problems.
