The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1-2, in an embodiment of the present invention, a fire extinguishing apparatus 100 is provided, which includes a housing 10 and a fire extinguishing assembly 30, the fire extinguishing assembly 30 is assembled in the housing 10, the housing 10 is provided with an explosion venting port, and the fire extinguishing assembly 30 can be exposed to the explosion venting port when being started, so as to achieve the fire extinguishing function.
The housing 10 includes a first housing 12 and a second housing 14, one end of the first housing 12 is hinged to one end of the second housing 14, the other end of the first housing 12 is snapped to the other end of the second housing 14, an assembly space is formed between the first housing 12 and the second housing 14, and the fire extinguishing assembly 30 is assembled in the assembly space. A primary explosion venting port 11 is formed between the first shell 12 and the second shell 14, a secondary explosion venting port 13 is formed in the first shell 12 and/or the second shell 14, and when the fire extinguishing assembly 30 in the shell 10 is started, the fire extinguishing assembly can be sprayed through the primary explosion venting port 11 and the secondary explosion venting port 13. Moreover, after the fire extinguishing assembly is started, pressure is firstly accumulated in the shell 10, and after the pressure is increased, the fire extinguishing assembly is sprayed from the first-stage explosion venting port 11 and the second-stage explosion venting port 13 in sequence, so that the pressure during spraying is improved, the spraying stroke is increased, and the fire extinguishing effect is improved.
The fire extinguishing assembly 30 comprises a packaging bag 32 and a fire extinguishing agent 34, wherein the packaging bag 32 is provided with a containing cavity, and the fire extinguishing agent 34 is flatly spread and vacuum-packaged in the containing cavity. When the fire extinguishing agent 34 is packaged, the fire extinguishing agent 34 is firstly bulk-packaged in the containing cavity of the packaging bag 32, then the fire extinguishing agent 34 in the containing cavity is spread, finally the inside of the containing cavity is vacuumized to package the fire extinguishing agent 34 in a vacuum manner, and the fire extinguishing agent 34 is fixed to be flat. Thus, no matter the vertically placed packaging bag 32 or the horizontally placed packaging bag 32, the fire extinguishing agent 34 is not deformed by being extruded and fixed, the fire extinguishing agent 34 is not accumulated to the bottom of the packaging bag 32 due to multiple times of vibration, the fire extinguishing agent 34 is prevented from being accumulated to the bottom of the packaging bag 32 and reducing the contact area with air when the vertically placed packaging bag 32 is placed, the fire extinguishing agent 34 and the air are ensured to have a larger contact area by placing the packaging bag 32 in any way, the combustion speed, the spraying pressure and the initial spraying speed of the fire extinguishing agent 34 during starting are better, and the fire extinguishing device 100 has a better fire-extinguishing impact effect.
It can be understood that when the containing cavity in the packaging bag 32 is vacuumized, the containing cavity can be vacuumized according to actual needs, and after the fire extinguishing agent 34 can be fixed, excessive vacuumizing is not needed. Moreover, the fire extinguishing agent 34 is vacuum-packed, which can prevent the fire extinguishing agent 34 from being affected with moisture, and prolong the service life of the fire extinguishing apparatus 100.
Optionally, the fire extinguishing agent 34 is an aerosol in one or any combination of powder, granule, tablet, or block form. It should be understood that when the aerosol fire extinguishing agent is in the form of powder, granule, tablet or block, the specific surface area per unit mass of the aerosol fire extinguishing agent is increased or the density per unit volume is decreased, so that once the aerosol fire extinguishing agent is ignited, the combustion will quickly diffuse, and a large amount of fire extinguishing substances are instantaneously released in a deflagration manner, thereby increasing the spraying speed and achieving a better fire extinguishing effect.
The aerosol on the market is compacted and then made into a shape of a grain, the burning speed of the grain is controlled by burning one surface of the grain, so that the stable spraying effect is achieved, the burning process is burning layer by layer, the burning area of the grain is limited, so that the aerosol burns and releases partial inert gas and metal particles, the metal particles seize free radicals to block a chain type burning reaction to extinguish fire, and the inert gas achieves the auxiliary fire extinguishing effect; the aerosol powder or the fragments of the aerosol are not pressed into a grain shape, but the aerosol of the powder or the fragments is scattered and piled in a packaging bag, once the aerosol is ignited, all the powder or the fragments are directly detonated, so that a large amount of inert gas is released instantly, the oxygen concentration in a space in unit time is reduced, and a better fire extinguishing effect is achieved.
Further, the pouch 32 is made of combustible material, does not inhibit the burning of the fire extinguishing agent 34 inside the pouch 32, and allows the fire extinguishing agent 34 to be discharged from the explosion vents in the housing 10 after burning. Moreover, when the fire extinguishing agent 34 is ignited, the fire can instantaneously burn through the packaging bag 32, the vacuum state of the containing cavity in the packaging bag 32 is broken, and the internally compressed fire extinguishing agent 34 can instantaneously loosen and contact with air to be rapidly burnt.
Further, the bag 32 is flexible, and when a vacuum is applied to the interior of the bag 32, the bag 32 can deform accordingly to reduce the volume of the chamber to hold the fire extinguishing agent 34 in a compressed state. Alternatively, the packaging bag 32 is configured to be flat, and the fire extinguishing agent 34 is spread along the extending direction of the packaging bag 32, so that when the fire extinguishing agent 34 is contained in the packaging bag 32, the packaging bag 32 adapted to be flat can be spread flat to obtain a larger outer surface, and a larger contact area with air is ensured when the fire extinguishing agent 34 is started.
In some embodiments, the fire extinguishing assembly 30 further includes a heat-sensitive wire 36, one end of the heat-sensitive wire 36 is enclosed in the containing cavity and contacts with the fire extinguishing agent 34, and the other end of the heat-sensitive wire 36 extends out of the packaging bag 32, so that when a fire occurs outside the packaging bag 32 and the temperature rises, the heat-sensitive wire 36 self-ignites and ignites the fire extinguishing agent 34 contacting with the heat-sensitive wire 36, so that the fire extinguishing agent 34 is activated to extinguish the fire.
In some embodiments, the fire extinguishing apparatus 100 further includes a supporting member (not shown) including a first supporting member and a second supporting member disposed in the housing at an interval, a flat clamping space is formed between the first supporting member and the second supporting member, and the fire extinguishing assembly 30 is clamped and fixed in the clamping space. Like this, suppose that the encapsulation bag 32 leaks behind the vacuum, the subassembly 30 of putting out a fire still is for the platykurtic by the spacing centre gripping of first support piece and second support piece, and fire extinguishing agent 34 still can not pile up in encapsulation bag 32 bottom when vertically placing encapsulation bag 32, further guarantees that fire extinguishing agent 34 has great area of contact with the air, guarantees fire extinguishing agent 34's start-up effect. Optionally, the first supporting member and the second supporting member are both arranged in a mesh plate shape, and the fire extinguishing assembly 30 is clamped and fixed by two parallel mesh plates so as to fix the fire extinguishing agent 34 and allow the fire extinguishing assembly 30 to be quickly contacted with air through mesh openings on the mesh plates for combustion, and the normal starting of the fire extinguishing agent 34 is not affected.
Based on the same concept, in an embodiment of the present invention, there is also provided the fire extinguishing assembly 30. The fire extinguishing assembly 30 comprises a packaging bag 32 and a fire extinguishing agent 34, wherein the packaging bag 32 is provided with a containing cavity, and the fire extinguishing agent 34 is flatly spread and vacuum-packaged in the containing cavity. When the fire extinguishing agent 34 is packaged, the fire extinguishing agent 34 is firstly bulk-packaged in the containing cavity of the packaging bag 32, then the fire extinguishing agent 34 in the containing cavity is spread, finally the inside of the containing cavity is vacuumized to package the fire extinguishing agent 34 in a vacuum manner, and the fire extinguishing agent 34 is fixed to be flat. Thus, no matter the vertically placed packaging bag 32 or the horizontally placed packaging bag 32, the fire extinguishing agent 34 is not deformed by being extruded and fixed, the fire extinguishing agent 34 is not accumulated to the bottom of the packaging bag 32 due to multiple times of vibration, the fire extinguishing agent 34 is prevented from being accumulated to the bottom of the packaging bag 32 and reducing the contact area with air when the vertically placed packaging bag 32 is placed, the fire extinguishing agent 34 and the air are ensured to have a larger contact area by placing the packaging bag 32 in any way, the combustion speed, the spraying pressure and the initial spraying speed of the fire extinguishing agent 34 during starting are better, and the fire extinguishing device 100 has a better fire-extinguishing impact effect.
Based on the same conception, in an embodiment of the present invention, an electrical apparatus is further provided, which includes a box body, an electrical device and the fire extinguishing apparatus 100, wherein the electrical device and the fire extinguishing apparatus 100 are both assembled in the box body, the fire extinguishing apparatus 100 is flat, and a plane of the flat extension of the fire extinguishing apparatus intersects with a bottom plate of the box body, so that the fire extinguishing apparatus 100 can be vertically or obliquely assembled in the box body, and is convenient to assemble in a narrow box body; meanwhile, for the vertical or inclined fire extinguishing device 100, although the packaging bag 32 can also be vertically or obliquely arranged, the fire extinguishing agent 34 in the fire extinguishing device 100 is flat due to vacuum sealing, and cannot be accumulated to the bottom of the packaging bag 32 under the action of self gravity or external vibration, so that the fire extinguishing agent 34 in the vertical or inclined packaging bag 32 still has a large outer surface area, and the fire extinguishing agent 34 is ensured to have a large contact area with air when being started, and a fire extinguishing effect is ensured.
