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.
Referring to fig. 1 in conjunction with fig. 2, an embodiment of the present application provides a fire extinguishing apparatus 100. The fire extinguishing apparatus 100 includes: a base 110, a cover 120, and an actuating member 130. The base 110 and the cover 120 enclose a cavity 101, and one end of the base 110 is hinged to one end of the cover 120. The other end of the base 110 and the other end of the cover 120 are detachably and fixedly connected, so that the base 110 and the cover 120 can be opened and closed relatively. An aerosol fire extinguishing agent 140 is disposed within the chamber 101. One end of the activation member 130 is positioned within the cavity 101 to ignite the aerosol fire suppressant 140. The base 110 and/or the cover 120 are provided with a hair spray opening 102.
Specifically, the spout 102 can be provided on the base 110, the cover 120, or at the junction of the base 110 and the cover 120. As shown in fig. 2, in the present embodiment, the hair spray opening 102 is provided at the junction of the base 110 and the cover 120.
The other end of the base 110 and the other end of the cover 120 may be connected by a snap or a threaded connection. In this embodiment, the fire suppression apparatus 100 further includes a threaded connection 150. The threaded connection 150 may be a screw, bolt, or the like.
The aerosol fire extinguishing agent 140 is ignited through the starting part 130, the aerosol fire extinguishing agent 140 is combusted to generate inert gas and metal particles, the inert gas and the metal particles are sprayed out through the spraying opening 102, the metal particles grab free radicals to block a chain type combustion reaction to extinguish fire, and the inert gas achieves an auxiliary fire extinguishing effect.
Due to the rapid burning of the aerosol fire extinguishing agent 140, the instantaneous pressure inside the cavity 101 is rapidly increased by a large amount of fire extinguishing substances generated after the burning of the aerosol fire extinguishing agent 140, so that the one end of the base 110 and the one end of the cover 120 are separated from the threaded connection 150, and the base 110 and the cover 120 are relatively opened.
In the fire extinguishing apparatus 100, if the aerosol fire extinguishing agent 140 explodes, the instantaneous pressure inside the cavity 101 increases sharply, so that one end of the base 110 and one end of the cover 120 are separated from the detachable fixed connection of the two, and the base 110 and the cover 120 are relatively opened. Because the other end of the base 110 is connected with the other end of the cover 120 in a hinged manner, when the base 110 and the cover 120 are opened relatively, the base 110 and the cover 120 cannot be thrown away, and further, other devices or people can be prevented from being injured by crashing.
In this embodiment, the aerosol fire extinguishing agent 140 is in the form of one or any combination of powder, granules, tablets, or blocks. It should be understood that when the aerosol fire extinguishing agent 140 is in the form of powder, granule, tablet or block, the specific surface area per unit mass of the aerosol fire extinguishing agent 140 is increased or the density per unit volume is decreased, so that once the aerosol fire extinguishing agent 140 is ignited, the combustion will rapidly diffuse, and a large amount of fire extinguishing substance is instantaneously released in a deflagration manner, thereby increasing the spraying speed and achieving a better fire extinguishing effect.
In one embodiment, the fire suppression apparatus 100 further includes a venting structure (not shown). The explosion venting structure is disposed on the base 110 and/or the cover 120. The explosion venting structure is used for releasing the pressure in the cavity 101 to the outside of the cavity 101.
Specifically, if the aerosol fire suppressant 140 deflagrates, the instantaneous pressure inside the cavity 101 increases dramatically. At this moment, the pressure in the cavity 101 is released to the outside of the cavity 101 through the explosion releasing structure, so that the instantaneous pressure in the cavity 101 is timely discharged, and the safety of the fire extinguishing device 100, other equipment and personnel can be further ensured.
Referring to fig. 3, in an embodiment, the base 110 and/or the cover 120 are provided with a pressure relief opening 103. The explosion venting structure includes a pressure relief member 160. The pressure relief member 160 is provided at the pressure relief port 103. The pressure relief member 160 includes a pressure-holding state and a pressure-releasing state, and when the pressure relief member 160 is in the pressure-holding state, the fire extinguishing substance is accumulated in the chamber 101. When the pressure relief member 160 is in a pressure relief state, the fire extinguishing substance is sprayed outward through the pressure relief member 160. When the aerosol fire extinguishing agent 140 burns and produces the fire extinguishing substance, the accessible makes pressure release 160 be in the suppress pressure state for the gathering of fire extinguishing substance in cavity 101, thereby the pressure increase in cavity 101 is favorable to improving the eruption pressure when pressure release 160 is in the pressure release state, thereby improves speed of putting out a fire and fire control effect.
Specifically, the pressure relief member 160 is configured to transition from a pressure-holding state to a pressure-relief state when the pressure in the cavity 101 reaches a preset value. As the fire suppressant material collects within the chamber 101, the pressure within the chamber 101 increases. When the pressure in the chamber 101 reaches a preset value, the pressure relief member 160 is triggered to change from a pressure-holding state to a pressure-relief state, so as to spray the fire extinguishing substance. The pressure relief member 160 is triggered directly by the pressure in the chamber 101 and has a simple structure and a rapid response.
Alternatively, the pressure relief member 160 may be a pressure relief diaphragm, an aluminum film, a pressure relief valve, or the like.
Further, when the pressure relief valve is adopted, the pressure relief valve is hermetically installed at the pressure relief opening 103, and when the pressure in the cavity 101 is smaller than a preset value, the pressure relief valve is turned off (i.e., the above-mentioned pressure-holding state). When the pressure in the chamber 101 is greater than or equal to the preset value, the pressure release valve is turned on (i.e., the pressure release state is described above), and the fire extinguishing substance in the chamber 101 is sprayed out through the pressure release valve.
In one embodiment, the pressure relief valve comprises a pressure relief cover that is movable under the urging of pressure within chamber 101. The pressure relief cover has an initial position and a pressure relief position. When the pressure relief cover is at the initial position, the pressure relief cover seals the pressure relief opening 103, and at the moment, the pressure relief valve is in a pressure-holding state. When the pressure in cavity 101 reached the default, the pressure release lid was pushed to the pressure release position to make pressure release opening 103 open, make the fire extinguishing substance in cavity 101 outwards erupt from pressure release opening 103, at this moment, the relief valve is in the pressure release state.
In particular, the pressure relief valve may comprise a connection. The connecting part is fixedly connected with the pressure relief cover. The connecting part is connected with the inner wall of the pressure relief opening 103 in a sliding way. The connecting portion and the inner wall of pressure relief port 103 have certain frictional force to when the pressure in cavity 101 is less than the default, be not enough to overcome the frictional force between the inner wall of connecting portion and pressure relief port 103, the pressure release lid keeps sealed pressure relief port 103, and the relief valve is in the state of suppressing the pressure. When the pressure in the cavity 101 reaches a preset value, the pressure in the cavity 101 overcomes the friction force between the connecting part and the inner wall of the pressure relief opening 103, and pushes the pressure relief cover to move to a pressure relief position.
It should be noted that the pressure relief valve may also be other mature prior art, and is not described herein again.
When the pressure relief diaphragm is adopted, the pressure relief diaphragm is hermetically arranged at the pressure relief opening 103 (i.e. the above-mentioned pressure-holding state). When the pressure in the chamber 101 reaches a predetermined value, the pressure relief diaphragm is broken (i.e., the above-mentioned pressure relief state). Further, at least one indentation is formed on the pressure relief diaphragm, when the pressure in the cavity 101 reaches a preset value, the pressure relief diaphragm is broken along the indentation, and the fire extinguishing substance in the cavity 101 is sprayed outwards through the broken part of the pressure relief diaphragm.
When the aluminum film is adopted, the aluminum film is sealed and arranged at the pressure relief opening 103 (namely, the pressure-holding state), when the pressure in the cavity 101 reaches a preset value, the aluminum film is broken under the pressure (namely, the pressure-releasing state), and the fire extinguishing substance in the cavity 101 is sprayed outwards through the broken part of the aluminum film.
In one embodiment, the activation component 130 is a heat-sensitive wire. One end of the heat-sensitive wire extends into the cavity 101, and the other end is located outside the cavity 101.
Specifically, one end of the heat-sensitive wire extends into the cavity 101, and the other end of the heat-sensitive wire is located outside the cavity 101. The aerosol fire suppressant 140 may be ignited by igniting the heat sensitive wire, thereby facilitating ignition of the aerosol fire suppressant 140.
In another embodiment, the initiating component 130 may also be an electrical initiator. The fire suppression apparatus 100 also includes a controller (not shown), a detector (not shown), and an electrical initiator (not shown). The detector is used for detecting fire and sending a fire signal to the controller. One end of the electrical initiator extends into the chamber 101. The controller is used to control the electrical initiator to ignite the aerosol fire suppressant 140.
Specifically, the controller may be an industrial personal computer, a PLC controller, an MCU controller, or the like. The detector may be a temperature sensitive detector. The temperature sensitive detector can detect the occurrence of fire by sensing temperature. The fire signal is a temperature abnormal signal. When the temperature detector senses that the temperature is abnormal, the temperature abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 140.
In other embodiments, the detector may also be a smoke detector. The smoke detector can detect the occurrence of fire by sensing the smoke concentration. The fire signal is a smoke concentration abnormal signal. When the temperature-sensing detector senses that the smoke concentration is abnormal, the smoke concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 140. The detector may also be a combustible gas detector. The smoke detector can detect the occurrence of fire by sensing the concentration of combustible gas. The fire signal is a combustible gas concentration abnormal signal. When the temperature-sensing detector senses that the concentration of the combustible gas is abnormal, a combustible gas concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 140.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
