Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to an aerosol fire extinguishing device. Background Art

[0002] With the development of new energy and the widespread application of industrial and commercial energy storage cabinets, cases of safety accidents involving energy storage batteries occur from time to time. If a fire in a single outdoor energy storage cabinet cannot be extinguished in time, a larger fire may occur in the entire energy storage cabinet. Aerosol fire extinguishing devices have the remarkable characteristics of high fire extinguishing efficiency, non-toxicity, safety and reliability, and can effectively extinguish Class B, Class C, and Class E fires in energy storage cabinets. However, industrial and commercial energy storage cabinets are in natural environments for a long time. If they are in a high humidity environment for a long time, it will inevitably cause the fire extinguishing device to absorb moisture and become damp, causing the fire extinguishing device to fail and fail to start normally when a fire occurs. In addition, when the aerosol fire extinguishing device is ignited, a large amount of heat energy will be generated. If the absorption of this heat cannot be solved, the aerosol fire extinguishing device will increase the fire risk of the energy storage cabinet. Utility Model Content

[0019] like Figures 1 to 2As shown, an aerosol fire extinguishing device includes a shell and an ignition wire 3, one end of the shell is provided with a nozzle 4 and a wire perforation, and further preferably, the nozzle 4 is multiple, and the nozzle 4 is used to spray a fire extinguishing agent. A sealing layer 8 is provided in the shell, and the sealing layer 8 is used to seal the nozzle 4. An igniter 5 and an aerosol generator 6 are provided in the shell, and the igniter 5 and the aerosol generator 6 are sealed in a sealing bag 9. A cooling layer is also provided in the shell, and the cooling layer is located between the nozzle 4 and the sealing bag 9. The ignition wire 3 passes through the wire perforation, the sealing layer 8, and the cooling layer in sequence and extends into the sealing bag 9 to contact the igniter 5. When a fire occurs, the igniter 5 is ignited by the ignition wire 3, and the aerosol generator 6 generates a large amount of hot aerosol. After the aerosol is cooled by the cooling layer, it breaks through the sealing layer 8 and sprays out from the nozzle 4. The present application absorbs the heat of the aerosol through the cooling layer, so that the fire extinguishing device sprays a low-temperature aerosol to avoid high heat from exacerbating the external fire. The present application achieves sealing of the igniter 5 and the aerosol generator 6 through the sealing bag 9, preventing the igniter 5 and the aerosol generator 6 from absorbing moisture and preventing the igniter 5 and the aerosol generator 6 from failing, thereby increasing the storage life of the fire extinguishing device, while ensuring that the aerosol generator 6 can quickly generate a large amount of aerosol when the igniter 5 is ignited. The present application seals the nozzle 4 through the sealing layer 8, which can further prevent moisture from entering the fire extinguishing device and improve the sealing performance of the fire extinguishing device.

[0020] A perforated plate 7 is also provided in the shell, and the perforated plate 7 is provided between the sealing layer 8 and the cooling layer. The perforated plate 7 is used to limit the cooling layer. By limiting the cooling layer by the perforated plate 7, the aerosol can be prevented from rushing out of the nozzle 4 of the cooling layer after absorbing heat.

[0021] The housing includes an end cap 1 and a storage tube 2, and the end cap 1 is threadedly connected to the storage tube 2. Further, a glue seal is provided at the threaded connection between the end cap 1 and the storage tube 2. Specifically, glue is first applied to the thread of the end cap 1 or the storage tube 2, and then the end cap 1 and the storage tube 2 are tightened to form a glue seal at the connection between the end cap 1 and the storage tube 2, thereby improving the sealing of the connection.

[0022] The wire through hole is provided with a tower-shaped wire sheath 11, the ignition wire 3 passes through the tower-shaped wire sheath 11, and a sealant 12 is provided in the tower-shaped wire sheath 11, and the sealant 12 can be AB glue. The tower-shaped wire sheath 11 protects the ignition wire 3 to prevent the ignition wire 3 from being worn. The sealant 12 provided in the tower-shaped wire sheath 11 can also improve the sealing performance between the ignition wire 3 and the tower-shaped wire sheath 11, and prevent moisture from entering the housing.

[0023] The nozzle 4 is arranged on the end cover 1 , and a sealing layer 8 is attached to the inner side of the end cover 1 , and the sealing layer 8 can seal the nozzle 4 .

[0024] The sealing layer 8 is aluminum foil. The aluminum foil used as the sealing layer 8 can effectively prevent moisture and humidity, and is easy to be broken by hot melt adhesive, thereby ensuring the sealing of the nozzle 4 and the timeliness of the aerosol spraying.

[0025] The cooling layer includes a plurality of cooling balls 10. Further, the diameter of the cooling balls 10 is larger than the hole diameter of the perforated plate 7.

[0026] The ignition wire 3 is a heat-sensitive wire.
