Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting and extinguishing, in particular to an intelligent self-starting fire extinguishing device based on perfluorohexanone fire extinguishing medium. Background Art

[0002] With the increasingly stringent restrictions on the use of traditional gaseous fire extinguishing agents such as halon, heptafluoropropane, and hexafluoropropane, perfluorohexanone fire extinguishing agent with good environmental performance is becoming more and more widely used. It has the characteristics of low fire extinguishing concentration, high fire extinguishing efficiency, high safety factor, non-conductivity, and no residue. It is suitable for fire protection in places where other fire extinguishing agents are not suitable for fire fighting and where there should be no significant secondary pollution after fire extinguishing, such as computer rooms, large data centers, power distribution rooms, cultural relics archives, and engine rooms of aircraft and ships.

[0003] Perfluorohexanone, a third-generation clean gas fire extinguishing agent, has a fire extinguishing mechanism described as a "molecular scalpel." This colorless, transparent liquid, upon vaporization, rapidly captures free radicals in combustion chain reactions, far less efficiently than traditional agents like heptafluoropropane. Laboratory data demonstrates that perfluorohexanone fire extinguishing systems, with their superior electrical insulation and highly effective fire extinguishing properties, have become a cutting-edge solution for modern electrical cabinet fire protection.

[0004] However, most of the fire extinguishing devices on the market are pressurized structures, which are large in size and weight, and are not easy to install and use, resulting in a narrow scope of application. At the same time, during use, after the perfluorohexanone medium is sprayed and atomized to extinguish the fire, the device cannot be used again, which is not conducive to assembly and disassembly and secondary utilization of added materials. Most of them are used for one-time fire extinguishing, resulting in waste of resources and increased use costs. Summary of the Invention

Moreover, under the action of the fixed pipe, it is convenient to inject perfluorohexanone from the mounting sleeve later into the inner side of the medium storage cylinder through the fixed pipe. At the same time, under the action of the engaging hole, it is convenient to engage with the connecting seat when the top cover is installed, so that the perfluorohexanone can be discharged and extinguished during fire extinguishing later.

[0015] Preferably, the connecting seat is fixedly mounted on the top side of the top cover, and a clamping sleeve is provided on the bottom side of the top cover, a No. 2 sealing ring is provided on the inner side of the clamping sleeve, and the size and shape of the bottom end of the connecting seat match the locking hole, and the top cover is mounted on the inner side of the positioning groove by bolts.

[0016] Through the above technical solution, since a ferrule is provided on the bottom side of the top cover, it is convenient to engage with the top end of the medium storage cylinder. At the same time, under the action of the No. 2 sealing ring, the sealing performance of the ferrule and the connecting end of the medium storage cylinder is improved, thereby avoiding leakage during use and improving the sealing performance. In addition, due to the size and shape of the bottom end of the connecting seat and the engaging hole, it is convenient to connect the bottom end of the connecting seat with the engaging hole during installation, thereby facilitating the circulation of perfluorohexanone. When installing the top cover, after engaging the top cover with the positioning groove on the top side of the shell, it is connected and fixed with bolts.

The bottom cover is installed on the inner side of the positioning groove by bolts.

[0020] Through the above technical solution, when a fire occurs, the temperature sensor detects and transmits the signal to the processing chip, and then the power of the ignition device is turned on to perform electric ignition. The gas generating agent is then ignited to react, causing the pressure inside the cavity to change, thereby pushing the piston to allow the perfluorohexanone inside the medium storage cylinder to enter the connecting seat and then be sprayed out through the nozzle. The perfluorohexanone is then vaporized to extinguish the fire source, and the screw and the starting cylinder are driven to rotate by rotating the adjusting seat, thereby facilitating the close fixation and distance control of the starting cylinder and the docking seat on the bottom side of the partition, thereby facilitating assembly and disassembly.
