Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
Detailed Description
The following description and the drawings sufficiently illustrate specific embodiments of the utility model to enable those skilled in the art to practice them. Other embodiments may involve structural, logical, electrical, process, and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others.
As shown in fig. 1, in some illustrative embodiments, there is provided a self-extinguishing device comprising: the fire extinguishing device comprises an initiating component 1, a sealing structure 2, a gas generating agent 3, a fixing component 11, a generating cabin 4, a firing pin 5, an actuating valve 7, a connecting pipe 12, a first cavity 10, a pressurizing gas 13, a second cavity 8, a fire extinguishing agent 9 and a nozzle 6.
The automatic fire extinguishing device can be placed in a place with fire hidden danger in a small space. The initiating component 1 will activate the gas generant 3 when the ambient temperature is high or an open flame is encountered. After the gas generating agent 3 is started, the inside of the fixing component 11 is of a sealing structure, and the top of the generation cabin is provided with the sealing structure 2 which can seal the top of the generation cabin after the triggering component triggers, so that high-pressure gas is generated to drive the firing pin 5 to generate downward kinetic energy. The striker 5 moves downward to open the trigger valve 7. After the start valve 7 is opened, the interior of the second cavity 8 is communicated with the nozzle 6 through a connecting pipe 13. Because of the existence of the pressurizing gas 13, the pressurizing gas 13 can overstock the second cavity 8 to deform, so that the fire extinguishing agent 9 is sprayed out through the nozzle 6, and the fire extinguishing effect is achieved. In the process, the device can be automatically started, so that the purposes of timely extinguishing fire and protecting property and life safety are achieved.
The fire extinguishing agent 9 in the automatic fire extinguishing device can be perfluoro-hexanone or water-based foam fire extinguishing agent. The perfluoro-hexanone is an important halon fire extinguishing agent substitute, is a fluorinated ketone compound, and is a clear, colorless and odorless liquid. The fire extinguishing mechanism of the water-based foam extinguishing agent is a physical fire extinguishing principle. The fire extinguishing agent mainly comprises hydrocarbon surfactant, fluorocarbon surfactant, flame retardant and auxiliary agent. Both of these agents may be ejected from the first chamber by compressed air.
The gas generating agent in the automatic fire extinguishing device can be gunpowder or a thermosensitive wire.
The initiating component in the automatic fire extinguishing device can be a thermosensitive wire or an electric initiating device.
The first cavity 14 in the automatic fire extinguishing device can be an aluminum bottle, and compared with the first cavities made of other materials, the aluminum bottle is lighter and safer.
The pressurizing gas in the automatic fire extinguishing device is pressurizing nitrogen, and the physical and chemical properties of the nitrogen are stable.
The sealing structure in the automatic fire extinguishing device can be silica gel, and after the initiating component is started, the silica gel can seal the top of the generation cabin.
The above examples are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited by the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present utility model should be made in the equivalent manner and should be included in the protection scope of the present utility model 。
