Description
Technical Field
[0001] The utility model relates to the technical field of fire fighting and extinguishing, in particular to a pipeline pressure-free mechanical fire extinguishing device. Background Art
[0002] At present, mechanical fire extinguishing devices have been widely used, covering both automatic and manual types. Its core working principle is to trigger the fire extinguishing mechanism by pressurizing the inside of the starting pipeline. When a fire occurs, a specific pressure relief method is used to create a pressure difference between the inside of the fire extinguishing device's agent bottle and the starting pipeline, thereby starting the fire extinguishing process. However, this type of pressurized fire extinguishing device faces many potential problems, such as internal pressure leakage in the starting pipeline caused by vibration, bumps, and damaged sealing rings, which makes the fire extinguishing device unable to work normally at critical moments.
[0003] On the other hand, common electronic fire extinguishing devices rely on energized control solenoid valves or other electrical devices to activate the fire extinguishing process. Although such devices do not require internal pressurization of the starter pipeline, their reliance on electricity makes them unsuitable for use in coal mines or places with special safety requirements.
[0004] In view of the above technical problems, it is necessary for technicians in this field to develop a new type of fire extinguishing device. The device should have the characteristics of no pressure in the starting pipeline, passive and non-electric pure mechanical type, and can be used in various places such as industrial and mining vehicles, industry, power, coal mines, etc. At the same time, the device should also be able to flexibly choose to use different types of fire extinguishing agents according to the needs of the fire extinguishing type, such as ultra-fine dry powder, water-based agents, perfluorohexanone, etc. Utility Model Content
