Problems solved by technology

[0005] The existing passive automatic fire suppression method for automobiles has low reliability, limited monitoring area, and is prone to false alarms; if it is not timely, it will start only after the entire area catches fire; more dry powder fire extinguishing agents are used, which is easy to cause damage to automobile engines and electrical components; The installation method is unreasonable, and it is easy to cause damage to the system itself, environmental components and occupants

Embodiment Construction

[0020] Automobiles in the present invention refer to various types of vehicles, not limited to passenger cars, MPVs, SUVs, engineering vehicles, passenger cars, commercial vehicles and the like.

[0021] The fire extinguishing agent can be selected but not limited to heptafluoropropane fire extinguishing agent, carbon dioxide fire extinguishing agent, haloalkane fire extinguishing agent and the like.

[0022] The hose can be selected but not limited to the preparation of materials whose softening temperature does not exceed 200°C.

[0023] Such as figure 1 Shown, automobile engine cover 1 also claims engine cover, front face cover, arranges and fixes a replaceable fire extinguishing agent container 2 (preferred steel seamless bottle) at its root (near the vehicle front windshield side), If it is fixed by structures such as not limited to snap rings and buckles, the container 2 contains the fire extinguishing agent; The fire extinguishing agent outlet of the container is conn...

Abstract

The invention discloses a passive type automobile fire automatic suppressing method and device. A container containing fire extinguishing agents is arranged in an automobile; a pressure valve is arranged at a fire extinguishing agent outlet of the container for the fire extinguishing agents, an outlet of the pressure valve communicates with a pressure storage hose in a linkage mode, and the pressure in the container is not larger than the pressure of the pressure storage hose; and when the interior of the automobile is on fire and burns, the pressure storage hose bursts, the fire extinguishingagents in the container are sprayed out under the pressure in the container for suppressing burning. The mounting position is reasonable, and damage to a system, environment pieces and passengers isavoided; damage of the used fire extinguishing agents to an engine and electrical parts of the automobile is avoided; and arrangement is convenient, a monitoring area is not limited basically, no power source is needed and thus reliability is high, and a fire origin can be automatically detected and suppressed timely during the fire initial period.

Description

technical field [0001] The invention belongs to the technical field of vehicle fire protection, and in particular relates to a technology capable of automatically suppressing vehicle fires after a vehicle catches fire. Background technique [0002] In the limited space of a car, electrical components and their circuits are densely arranged; gasoline is flammable. Automobile fires usually start from one part of the fire and then spread. In about one minute, there is a flame at the ignition point accompanied by a slight white smoke, which can be extinguished with a small amount of fire extinguishing agent; It is only possible to extinguish the fire area if the agent covers the fire area; in about three minutes, the fire is basically out of control, and even if it can be extinguished, the vehicle is basically scrapped. [0003] Existing methods use vehicle-mounted portable fire extinguishers more. When the car is caught on fire and the fire extinguisher is manually operated, t...
