Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fire fighting equipment, and specifically relates to a mobile fire fighting isolation mechanism. BACKGROUND

[0002] With the continuous increase of charging station construction, the number of charging piles increases geometrically, it is difficult to extinguish the fire after the charging vehicle catches fire, and the safety risk also increases synchronously. The mainstream new energy vehicles are generally installed with lithium ion batteries, and lithium is a lively metal. The fire is induced by the short circuit of the circuit, the leakage of the circuit and the fault of the single battery, and the problem of thermal runaway occurs. The flame sprayed by the on-fire vehicle is easy to ignite the surrounding vehicles or equipment when the flame is effectively isolated.

[0003] The charging vehicle fire accident has strong randomness, fast ignition speed, long burning time, great potential danger, and the risk of toxic gas release and explosion. At present, part of the charging stations in the system is constructed separately, and part of the charging stations is constructed together with the gas station. The gas station has many vehicles entering and leaving, and the gas filling area and the oil tank area are flammable and explosive places. In related experiments, it is shown that during the burning experiment of the new energy vehicle battery, the battery needs only five or six seconds from the beginning of burning to violent burning, and there is a possibility of flame and a large amount of spatter during the burning process. Since the charging station has no flame isolation measures during the waiting for fire rescue, it is easy to cause the spread of fire, ignite the surrounding charging vehicles, and even affect the safe operation of the gas station equipment, forming secondary disasters.

[0004] At present, there is no effective way to prevent the fire caused by the thermal runaway of the battery, and the root cause is the battery itself. The current extinguishing method can only isolate the fire, continuously spray water to the part of the power battery to cool it down, prevent the spread of the fire, and wait for the power battery to burn out. At present, each charging station is only equipped with a fire extinguisher at the charging site, and there is no measure to isolate the fire of the on-fire vehicle. UTILITY MODEL CONTENTS
