A fire extinguishing device for spontaneous combustion of automobiles

Abstract

The patent application relates to the technical field of A62C3 / 00, in particular to a fire extinguishing device for spontaneous combustion of an automobile. The fire extinguishing device comprises a high-pressure gas device, a dry powder tank, a metal hose and an air flow channel, wherein the outlet of the high-pressure gas device is connected with the inlet of the air flow channel, the bottom ofthe dry powder tank is connected with the side wall of the air flow channel, and the outlet of the air flow channel is connected with the metal hose; the high-pressure gas device comprises an expansion thermometer, a cam is arranged on the outer ring of the expansion thermometer, a first working diaphragm is arranged on the high-pressure gas device, a first steel needle is arranged on the first working diaphragm, a box body is arranged on one side close to the tip of the first steel needle, and a film is arranged on the part of the box body facing the first steel needle; and a rotating plate is arranged on the air flow channel corresponding to the dry powder tank, a second steel needle is arranged on the rotating plate, and a second working diaphragm is arranged at the bottom of the dry powder tank. According to the fire extinguishing device provided by the invention, dry powder and high-pressure gas are separately arranged, and then the high-pressure gas drives the dry powder into themetal hose according to the Bernoulli principle, thereby achieving the effect of quickly extinguishing fire.

Description

technical field [0001] The invention relates to the technical field of A62C3 / 00, in particular to a fire extinguishing equipment. Background technique [0002] With the gradual improvement of living standards, cars are more and more integrated into our daily lives, bringing many conveniences to people's lives, but sometimes they can also become dangerous potential killers, such as cars spontaneously igniting or catching fire after a crash, mainly cars The engine part of the head is prone to fire. The current car fire extinguishing device usually needs to be opened manually. When the car spontaneously ignites, the inexperienced driver will easily flee the car due to panic and forget to press the car fire extinguishing device, causing the car fire to intensify or even explode. Therefore, manual car fire extinguishing The range and utility of the device is very limited. [0003] In view of the above problems, the authorized publication number is CN 103845830B, which discloses...
