Detailed Description
The following further description is made with reference to the drawings and specific embodiments.
The first embodiment is as follows:
as shown in fig. 1 and 2, the present embodiment provides a fixed type non-pressure-storing fire extinguisher 100 for fixing in a narrow space to detect and extinguish a fire in the space. The fixed non-pressure-storage fire extinguisher 100 mainly comprises a storage bag 10 and a driving device 20 arranged in the storage bag 10, wherein the storage bag 10 is made of soft plastic materials, the soft plastic materials comprise but are not limited to PP, PE or PTFE, the materials are low in price, the materials are easy to obtain, the processing is convenient, and the production cost of products is favorably reduced.
The storage bag 10 is in the form of a flat bag for containing the fire extinguishing agent, and has explosion venting structures 11 provided on the left and right sides, and the explosion venting structures 11 are easily ruptured under high pressure, so that the fire extinguishing agent 30 inside mainly erupts from the explosion venting structures 11 under high pressure and is sprayed outward.
The explosion venting structure 11 of the present embodiment may be various, including but not limited to: firstly, the explosion venting structure 11 is formed by splicing two plastic sheets through bonding, fusing or laser welding and other processes, and the compressive strength of the explosion venting structure is smaller than that of other parts of the storage bag 10; the storage bag 10 is of an integral structure, but the bag wall of the explosion venting structure 11 is slightly thinner than other parts, so that the pressure resistance strength of the part is relatively smaller, and the part is easier to break than other parts.
The fire extinguishing agent 30 of the present embodiment can be fluid or encapsulated into capsule-shaped perfluorohexanone, which is clean and environmentally friendly and can be used as a fire extinguishing substance in almost all situations including precision instruments and circuits, so that the fixed non-pressure-storing fire extinguisher 100 of the present embodiment has a full-scale application range.
The driving device 20 is used for detecting a fire and automatically starting when the fire is detected, and specifically comprises an air storage bag 21 and a sealing member 22 which is positioned at one end of the air storage bag 21 and used for sealing an opening of the air storage bag 21, wherein an air generating device 23 and a trigger 24 are arranged in the air storage bag 21.
The gas generating device 23 of the present embodiment is a gas generating agent capable of rapidly generating aerosol when burning, and the trigger 24 may be an electric heater or a heat-sensitive wire. The electric heater is wrapped in the gas production medicament, is connected with an external power supply through a wire, and supplies power to the electric heater by the external power supply; the heat-sensitive wire extends from the inside to the outside of the gas generating agent and is used for sensing the ambient temperature. When the environmental temperature rises to reach the ignition point of the heat-sensitive wire, the heat-sensitive wire is self-ignited and extends into the gas storage bag 21 to trigger the gas generating agent to react.
The gas storage bag 21 of the present embodiment is made of a hard material, and the sealing member 22 is fixedly connected with the gas storage bag 21 by a sealant.
When a fire disaster occurs, the trigger 24 is electrified to start heating or spontaneous combustion occurs, because the trigger 24 is wrapped in the gas generating agent, the high temperature generated by the trigger 24 can be efficiently conducted to the gas generating agent, when the temperature reaches the reaction critical point of the gas generating agent, a large amount of aerosol can be rapidly generated, the aerosol is rapidly accumulated in the narrow gas storage and generation bag 21 to form high-pressure gas, when the pressure of the formed high-pressure gas exceeds the tolerance limit of the gas storage and generation bag 21, the gas storage and generation bag 21 bursts, and the high-pressure gas breaks through the gas storage and generation bag 21 and then enters the storage bag 10. The fire extinguishing agent 30 breaks through the explosion venting structure 11 under the action of the explosion force, and after the explosion venting structure 11 cracks, the fire extinguishing agent 30 inside is sprayed out from the explosion venting structure 11, so that the fire extinguishing action is implemented.
In order to enable the gas generating agent to generate high-pressure gas as fast as possible, the gas generating agent of the embodiment is in a powder shape and can be ignited quickly by the high temperature generated by the trigger.
Further, the storage bag 10 is provided with a transfer port 12, the transfer port 12 is made of a hard plastic material, and is hermetically connected with the storage bag 10 through laser welding or a heat sealing machine, so that the storage bag 10 forms a structure similar to a jelly bag, and the transfer port 12 is used for filling a fire extinguishing agent.
In addition, the adapter 12 is adapted to be sealingly connected to the closure 22 of the drive 20 to enclose the fire suppressant 30 within the storage bag 10.
In this embodiment, the sealing member 22 is further provided with a wire hole 221 for allowing the electric wire or the heat-sensitive wire to pass through the driving device 20 to the outside of the driving device 20 for connecting an external power source or detecting an external temperature.
It can be seen that the fixed non-pressure-storage fire extinguisher 100 of the present embodiment pressurizes the fire extinguishing agent 30 in the storage bag 10 by bursting the gas storage bag 21 until the explosion venting structure 11 is broken by pressing, so that the fire extinguishing agent 30 is sprayed out from the explosion venting structure 11, thereby achieving automatic fire extinguishing and high fire extinguishing efficiency.
Referring to fig. 3, the fixed type non-pressure-storing fire extinguisher 100 of the present embodiment is provided in a housing 200, and the housing 200 is also flat and has a height and a width corresponding to the fixed type non-pressure-storing fire extinguisher 100. The housing 200 has a receiving space 210 with both ends opened therein, and the receiving space 210 is used for receiving the fixed type non-pressure storage fire extinguisher 100. The openings at the two ends of the accommodating space 210 correspond to the explosion venting structures 11 disposed at the left and right sides of the storage bag 10, respectively, and when the explosion venting structures 11 burst, the fire extinguishing agent 30 is sprayed outwards from the openings to extinguish the fire.
In order to allow the fixed type non-pressure storage fire extinguisher 100 to be stably installed in the housing 200, it is preferable that the entire height of the fixed type non-pressure storage fire extinguisher 100 is substantially the same as the height of the receiving space 210, and the fixed type non-pressure storage fire extinguisher 100 is tightly fitted with the housing 200, so that the fixed type non-pressure storage fire extinguisher 100 does not slip out, and thus, it is not necessary to fix the fixed type non-pressure storage fire extinguisher 100 using a limit structure or screws, etc. The sealing member 22 of this embodiment is further provided with a rib 222 (shown in fig. 2), the rib 222 is disposed adjacent to the wire through hole 221, and the height of the rib 222 is greater than the diameter of the electric wire or the heat-sensitive wire. So that the electric wire or the heat-sensitive wire can not be extruded when the electric wire or the heat-sensitive wire is installed, and the higher the convex rib is, the larger the space where the heat-sensitive wire is positioned is, the more sufficient the air is, and the normal combustion of the heat-sensitive wire is facilitated.
In addition, the present embodiment further includes a mounting hole 220 formed in the housing 200 for fixing the housing 200 and the fixed non-pressure storage fire extinguisher 100 at a fire extinguishing place without movement or shaking.
Example two:
referring to fig. 4, the structure of the fixed non-pressure-storing fire extinguisher 100 according to the present embodiment is substantially the same as that of the first embodiment, except that the gas storage bag 21 is made of a soft plastic material, and the sealing member 22 and the gas storage bag 21 are hermetically connected by laser welding or a heat sealing machine.
Further, the gas storage bag 21 is made of elastic material, and the high-pressure gas 25 generated by the gas generating device 23 gradually inflates the gas storage bag 21 to squeeze the fire extinguishing agent 30 in the storage bag 10. When the fire extinguishing agent 30 reaches a sufficient pressure, the explosion venting structure 11 is broken after reaching the pressure-resistant limit, so that the fire extinguishing agent 30 is sprayed out from the explosion venting structure 11, thereby implementing automatic fire extinguishing.
Specifically, the gas generating device 23 of the present embodiment may be a gas generating agent capable of rapidly generating aerosol when burning, and the trigger 24 may be an electric heater or a heat-sensitive wire. The electric heater is wrapped in the gas production medicament, is connected with an external power supply through an electric wire, and is powered by the external power supply. When a fire disaster occurs, the trigger 24 starts to heat after detecting the fire disaster and ignites the gas generating agent, the gas generating agent rapidly generates a large amount of aerosol, the high-pressure gas 25 is formed in the gas storage bag 21 and the pressure is continuously increased along with the continuous generation of the aerosol, so that the fire extinguishing agent 30 in the storage bag 10 is continuously extruded, when the pressure of the fire extinguishing agent 30 is increased to exceed the tolerance limit of the explosion venting structure 11, the explosion venting structure 11 is broken, and the fire extinguishing agent 30 is sprayed out from the explosion venting structure 11, so that the automatic fire extinguishing is implemented.
In other embodiments, the gas generator 23 may be a cylinder containing compressed inert gas, and the trigger 24 may be a valve or a valve actuator capable of opening the cylinder. When a fire breaks out, the trigger 24 detects the fire and opens the valve, so that the compressed gas in the steel cylinder enters the gas storage bag 21, the gas storage bag 21 expands, and the fire extinguishing agent 30 is extruded. With the continuous release of the compressed gas, high-pressure gas 25 is formed in the product storage bag 21, the pressure is gradually increased, the fire extinguishing agent 30 is further pressed, when the pressure of the fire extinguishing agent 30 is increased to exceed the tolerance limit of the explosion venting structure 11, the explosion venting structure 11 is broken, the fire extinguishing agent 30 is sprayed out from the explosion venting structure 11, and therefore automatic fire extinguishing is carried out.
It can be seen that the fixed non-pressure-storage fire extinguisher 100 of the present embodiment pressurizes the fire extinguishing agent 30 in the storage bag 10 by expanding the gas storage bag 21 until the explosion venting structure 11 is broken by pressing, so that the fire extinguishing agent 30 is sprayed out from the explosion venting structure 11, thereby achieving automatic fire extinguishing and having high fire extinguishing efficiency.
In summary, the storage bag with the explosion venting structure is used for containing fire extinguishing agents such as perfluorohexanone, the driving device is arranged in the storage bag, the trigger and the gas generating agent are arranged in the driving device, the trigger is used for triggering the gas generating agent to rapidly generate high-pressure gas when a fire disaster is detected, and the storage bag is extruded and burst after the high-pressure gas breaks through the gas generating storage bag along with the continuous increase of the air pressure in the driving device, so that the fire extinguishing agents such as perfluorohexanone in the storage bag are sprayed out, and the fire extinguishing action is started. The utility model integrates the detection function and automatic start, can be conveniently installed in a protected area, and can ensure that the product volume is smaller by adopting a non-pressure-storage fire extinguishing agent, thereby being installed in a narrow space to safely extinguish fire in the space such as a lithium battery pack and the like.
