This utility model discloses an aerosol intelligent fire protection system for highway tunnels, comprising several mounting slots evenly arranged on the side wall of the tunnel body. An aerosol fire extinguishing material storage tank is placed in each mounting slot. A first discharge pipe and a second discharge pipe are respectively installed on the side surface of the aerosol fire extinguishing material storage tank. A nozzle is installed at the end of both the first and second discharge pipes. A shape memory alloy valve that opens at high temperatures is installed on the first discharge pipe, and a solenoid valve is installed on the second discharge pipe. The two discharge pipes on the aerosol fire extinguishing material storage tank are respectively equipped with a solenoid valve and a shape memory alloy valve. The solenoid valve can be used for active fire extinguishing, while the shape memory alloy valve can achieve passive fire extinguishing when the solenoid valve fails (power failure, damage), thus improving the reliability of the fire protection system.

The utility model relates to an electric automobile fire extinguishing device, including car bottom shower device and at least one set of fireproof partition, the main part of car bottom shower device is metal pipe frame, the axis direction of the upward side of metal pipe frame sets up a plurality of first spout for from below to upward water spray, the downward side of metal pipe frame is fixed with first wheel, the bottom of fireproof partition is fixed with second wheel, the metal pipe frame still is fixed with the horizontal quick -wired port of intercommunication with it, to connect fire -fighting water pipe with convenience, the utility model discloses a movable car bottom shower device and fireproof partition to realize the quick isolation of accident vehicle and surrounding vehicle and the directional fire extinguishing cooling of battery part, the car bottom shower device of the utility model adopts the pipe frame structure, and the simple structure is convenient to operate, through the telescopic moving rod, it can be pushed to the bottom of the vehicle on fire safely, the utility model adopts the fireproof partition of splicing to the quick isolation of accident vehicle, can effectively control the spread of fire.

The application relates to the technical field of fire extinguishing agents, and particularly discloses a foam fire extinguishing agent compounded by anionic Gemini surfactants and a preparation method thereof, which comprises the following components in percentage by mass: 5-15% of anionic Gemini surfactants; 0.5-3% of fluorocarbon surfactants; 3-9% of hydrophilic monomer oligomers; 2-5% of zwitterionic surfactants; 1.0-2.5% of nonionic surfactants; 3-12% of anti-burning agents; 2-7% of cosolvents; and the balance of water. The biodegradable short-chain fluorocarbon surfactants are precisely compounded with anionic Gemini surfactants of specific structures, hydrophilic monomer oligomers and the like, and a preparation process of step-by-step construction is adopted, so that the environmental friendliness is remarkably improved, the performance of the fire extinguishing agent is comprehensively broken through, the water film on the oil surface is ensured to be rapidly spread and rapidly extinguished, the foam covering layer is endowed with super-strong mechanical stability and thermal stability, the anti-reignition time is greatly prolonged, and the purposes of efficient fire extinguishing, long-lasting anti-burning and environmental friendliness are finally achieved.
