Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1 to 5, an aerosol fire extinguishing device with a pressure release structure comprises an outer cylinder 1 and a fire extinguishing agent grain 2 arranged in the outer cylinder 1, wherein one end of the fire extinguishing agent grain 2 is connected with the tail end of a starting component 3, a front cover 4 is arranged on the front side of the outer cylinder 1, a nozzle 5 and a pressure release opening 10 are formed in the surface of the front cover 4, the outer side of the front cover 4 is connected with a pressure release diaphragm 6, the pressure release diaphragm 6 shields the pressure release opening 10, and a spray hole 6.1 overlapped with the nozzle 5 is formed in the surface of the pressure release diaphragm 6. In the normal fire extinguishing process, as the spray hole 6.1 on the surface of the pressure release diaphragm 6 coincides with the spray hole 5, aerosol fire extinguishing substances can be sprayed normally along the spray hole 5 and the spray hole 6.1, and in the normal spraying process, the pressure on the pressure release diaphragm 6 at the pressure release opening 10 is insufficient to cause the pressure release diaphragm 6 to be damaged or fall off; when the spraying pressure in the fire extinguishing device is larger than the preset pressure, the pressure at the pressure relief opening 10 is suddenly increased, the pressure on the pressure relief diaphragm 6 is enough to cause the pressure relief diaphragm 6 to be damaged or fall off, so that the pressure relief opening 10 is exposed, and the pressure relief process is performed in time.
Preferably, the front cover 4 is bonded or welded to the pressure release membrane 6.
Preferably, the nozzles 5 and the pressure relief openings 10 are distributed on the surface of the front cover 4 in an annular array.
Preferably, the nozzles 5 are distributed on the outer ring of the front cover 4, and the pressure relief openings 10 are distributed on the inner ring of the front cover 4.
Preferably, a coolant 7 is arranged between the fire extinguishing agent grain 2 and the nozzle 5, and a separation net 8 is arranged in the coolant 7. After the separation net 8 is arranged in the coolant 7, a cavity structure can be formed in the coolant 7, so that the coolant 7 can be partitioned to form a buffer space, the impact force of the fire extinguishing substance when passing through the coolant 7 is effectively weakened, and meanwhile, the contact area of the coolant 7 and the aerosol fire extinguishing substance is increased due to the cavity structure formed by the separation net 8, so that a better cooling effect is realized.
More preferably, the position where the coolant 7 contacts the end face of the fire extinguishing agent grain 2, the middle part of the coolant 7 and the position where the coolant 7 contacts the nozzle 5 are all provided with a separation net 8, and the separation net 8 is of a cambered surface cover net structure with a wide middle part and two narrow ends. As shown in fig. 1, after the separation net 8 is arranged at the position where the coolant 7 contacts with the end face of the fire extinguishing agent grain 2, the coolant 7 can be ensured not to press the tail end of the starting component 3, and the failure phenomenon in the starting ignition process can be prevented; after the separation net 8 is arranged in the middle of the coolant 7, a cavity structure can be formed in the coolant 7, so that a buffer space can be formed, and the impact force of fire extinguishing substances during passing can be effectively weakened; after the separation net 8 is arranged at the contact position of the coolant 7 and the nozzle 5, the position of the nozzle can be effectively prevented from being blocked by the coolant 7, so that the fire extinguishing substance can be smoothly sprayed out from the nozzle 5. When the aerosol fire extinguishing device adopting the chemical coolant is sprayed at present, the chemical coolant can be gradually melted, collapsed and accumulated, and the risk of blocking a spraying channel exists; the separation net 8 with the cambered surface cover net structure has a certain radian, so that the contact area of the cooling agent 7 and aerosol fire extinguishing substances can be increased, a better cooling effect is realized, and as the high-temperature cooling agent 7 is gradually consumed, the melted cooling agent 7 can gradually collapse towards two sides of the separation net 8 under the action of gravity, and the fact that a channel close to the middle is not blocked in the later stage of spraying the fire extinguishing substances by the fire extinguishing device is ensured.
More preferably, a silica gel coating layer 11 is further arranged between the surfaces of the fire extinguishing agent grain 2 and the coolant 7 and the inner side of the outer cylinder 1. After such design, the silica gel coating layer 11 has a heat insulation effect when the fire extinguishing device is sprayed, and prevents the temperature of the shell from being too high.
Preferably, the front side of the outer cylinder 1 is in threaded fit with the front cover 4, the rear side of the outer cylinder 1 is provided with a rear cover 9 in threaded fit with the front cover, and the rear cover 9 is provided with a through hole for penetrating the starting component 3.
Preferably, a support 12 is also provided between the bottom of the extinguishing agent column 2 and the rear cover 9. The supporting piece 12 can prevent the bottom temperature of the fire extinguishing device from being too high on one hand, and can support the starting component 3 at a certain distance on the other hand, so as to prevent the fire extinguishing agent grain 2 from damaging the starting component 3 by extrusion.
Preferably, the starting part 3 is an electric ignition head or a heat-sensitive wire structure. In this embodiment, when the starting member 3 is in the form of an electric ignition head, the starting member in fig. 1 is in the form of an electric ignition head, which is connected to a fire detection device, which is a temperature sensor and/or a smoke sensor. When fire, overheat and other conditions occur, the fire detection device detects the high-temperature environment generated by the fire, and then sends a signal to the microprocessor, and the microprocessor controls the starting component 3 to ignite the fire extinguishing agent grain 2. When the starting component 3 is of a thermosensitive line structure, the thermosensitive line structure is simpler, so that the fire extinguishing agent column 2 can be automatically started when a fire disaster occurs when the thermosensitive line is adopted, and the thermosensitive line can directly ignite the fire extinguishing agent column 2 without being matched with an additional fire disaster detection device and other external equipment.
The working principle of the embodiment is as follows:
when a fire occurs outside, the starting part 3 ignites the fire extinguishing agent grain 2, the fire extinguishing agent grain 2 in the embodiment is a grain pressed by aerosol generating agent, and the fire extinguishing agent grain 2 burns to generate fire extinguishing substances such as aerosol or gas; the fire extinguishing substances sequentially pass through the separation net 8 and the coolant 7, and as the separation net 8 can form a cavity structure in the coolant 7, a buffer space can be formed, so that the impact force of the fire extinguishing substances during passing is effectively weakened, the contact area of the coolant 7 and the aerosol fire extinguishing substances is increased, and a better cooling effect is realized; in the normal fire extinguishing process, as the spray hole 6.1 on the surface of the pressure release diaphragm 6 coincides with the spray hole 5, aerosol fire extinguishing substances can be sprayed normally along the spray hole 5 and the spray hole 6.1, and in the normal spraying process, the pressure on the pressure release diaphragm 6 at the pressure release opening 10 is insufficient to cause the pressure release diaphragm 6 to be damaged or fall off; when the spraying pressure in the fire extinguishing device is larger than the preset pressure, the pressure at the pressure relief opening 10 is suddenly increased, the pressure on the pressure relief diaphragm 6 is enough to cause the pressure relief diaphragm 6 to be damaged or fall off, so that the pressure relief opening 10 is exposed, and the pressure relief process is performed in time.
The above embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments of the present utility model may be arbitrarily combined with each other without collision. The protection scope of the present utility model is defined by the claims, and the protection scope includes equivalent alternatives to the technical features of the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
