Description

TECHNICAL FIELD

[0001] The utility model relates to perfluorohexanone fire extinguishing technical field, concretely relates to a perfluorohexanone fire extinguishing device. BACKGROUND

[0002] Perfluorohexanone is a colorless, odorless and transparent liquid at room temperature, which has a very high heat capacity and is mainly used as a fire extinguishing agent. Perfluorohexanone can rapidly decompose and release inert gas, rapidly evaporate when a fire occurs, and generate colorless and odorless gas. These gases have high inertness, can reduce the oxygen concentration in the fire area, thereby suppressing the combustion of flames and preventing the spread of fire. In addition, a thin film can be formed on the surface of the burning material to prevent oxygen from contacting the fuel, thereby inhibiting the further spread of flames.

[0003] Currently, existing mine fire extinguishing devices mainly use perfluorohexanone fire extinguishing devices with cabinet structures. The perfluorohexanone stored in the cabinet is sprayed through the nozzles protruding from the side walls of the cabinet to extinguish nearby flames. However, in actual use, the direction of the nozzles is usually fixed, making it impossible to target the spray for extinguishing the fire, which often results in poor extinguishing effect and greatly affects the practicality of the device. SUMMARY

By setting a transfer cylinder and a middle nozzle, and arranging multiple side nozzles in an annular array outside the middle nozzle, and by cooperating with the connecting rod, sliding block, support frame, gear ring, and transmission gear, the connecting rod can drive the multiple side nozzles to rotate simultaneously on the transfer cylinder. This allows the side nozzles to be controlled to fold inward and approach the middle nozzle or to disperse outward and move away from the middle nozzle. When folding inward and approaching, the perfluorohexanone can be concentrated and sprayed to extinguish the flames. When dispersing outward and moving away, the perfluorohexanone can be sprayed in a wider range to extinguish the flames. This allows the perfluorohexanone to be sprayed as needed for fire extinguishing, greatly improving the use effect of the device and solving the above-mentioned deficiencies in the art.
