As described in the background, in a fire fighting facility, in order to ensure fire safety and reliability of the fire fighting facility, maintenance of each part within the fire fighting facility is required periodically. Especially, for some very important devices, the devices need to be replaced regularly, so that the device can be guaranteed to alarm, extinguish fire and the like in time and quickly when a fire occurs, and people can be protected and navigated for life and property safety. However, for the later maintenance of the fire fighting equipment, the later use cost of the fire fighting equipment is increased, so that the fire fighting cost is high. In order to reduce the fire fighting costs, the applicant has proposed a separate fire extinguishing apparatus.
Fig. 1 shows a schematic structural view of a two-piece fire extinguishing apparatus 100 according to a preferred embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.
Referring to fig. 1, a split type fire extinguishing apparatus 100 according to a preferred embodiment of the present invention includes a fire extinguishing unit 110, a power unit 120, and a starter 130. It should be noted that, in practical applications, the split-type fire extinguishing apparatus 100 may be arranged horizontally, vertically or obliquely according to different installation conditions, installation spaces and installation positions.
The fire extinguishing unit 110 includes a fire extinguishing container 111, a sealing piston 112, and a fire extinguishing agent 113. The sealing piston 112 is accommodated in the fire extinguishing container 111 and is in sliding contact with the inner wall of the fire extinguishing container 111 to divide the space inside the fire extinguishing container 111 into a first chamber 1111 and a second chamber 1112. The side wall of the fire extinguishing container 111 is opened with an air inlet 1113 communicating with the first chamber 1111 and an outlet 1114 communicating with the second chamber 1112.
The fire suppressant 113 is contained within the second chamber 1112. The fire extinguishing agent 113 may be a gas fire extinguishing agent or an aerosol fire extinguishing agent. Specifically, in this embodiment, the fire extinguishing agent 113 is a perfluorohexanone fire extinguishing agent. The perfluorohexanone fire extinguishing agent may be a fire extinguishing agent containing only perfluorohexanone, or may be a fire extinguishing agent containing perfluorohexanone. The perfluorohexanone fire extinguishing agent is vaporized at the moment of contact with flames on the fire scene or a protected piece which is about to catch fire, so that the aim of temperature reduction and fire extinguishment is fulfilled. And perfluorohexanone has advantages such as environmental protection performance is high, corrosivity is low, easily clearance, so set up fire extinguishing agent 113 into perfluorohexanone fire extinguishing agent, not only can improve above-mentioned split type extinguishing device 100's fire extinguishing effect, but also make above-mentioned split type extinguishing device more green, still be favorable to the scene clearance after the conflagration rescue in addition.
The first chamber 1111 and the second chamber 1112 may be variable in size as the sealing piston 112 slides within the fire extinguishing container 111. When the fire extinguishing apparatus 100 is not in use, the fire extinguishing agent 113 is contained in the second chamber 1112, and the first chamber 1111 is the smallest, the sealing piston 112 may be infinitely close to the inlet 1113, so as to infinitely reduce the size of the first chamber 1111.
The power unit 120 includes a power container 121 and a gas generating element 122 housed in the power container 121. An exhaust 1211 is formed on a sidewall of the power container 121. The power container 121 is detachably mounted to an outer wall of the fire extinguishing container 111, and allows the exhaust 1211 and the intake 1113 to communicate with each other. The power container 121 and the fire extinguishing container 111 are both hollow structures, and the detachable connection between the power container 121 and the fire extinguishing container 111 can be realized directly in a detachable mode, and can also be realized by being detachably connected with other components such as pipelines and the like.
The actuator 130 is detachably mounted to the power container 121. Actuator 130 includes an initiator (not shown). The initiator is coupled to the gas generant 122 and is configured to activate the gas generant 122 to produce pressurized gas. The gas generating member 122 may generate high pressure gas by combustion, chemical reaction, etc. The gas generant 122 generates a quantity of high pressure gas upon actuation of the initiator.
In particular, in one embodiment, the initiator is a pyrotechnic structure, such as a friction ignition device, an electronic ignition device, or the like. The gas generant member 122 is a combustible material such as gunpowder or the like. The initiator is used to ignite the gas generant 122 to produce high pressure gas. In use, the initiator is activated to generate a spark, flame, etc. that ignites the gas generant 122 to generate a quantity of high pressure gas.
In another embodiment, the initiating element is a pyrotechnic structure. The gas generating member 122 includes a housing case (not shown), a safety plate (not shown), and a compressed gas (not shown). The initiator is used to ignite the compressed gas to form the high pressure gas. A gas injection port (not shown) is formed at a portion of the sidewall of the housing facing the exhaust port 1211. The safety blocking piece is arranged at the gas jet orifice and used for blocking the gas jet orifice and automatically conducting when high-pressure gas is formed in the containing shell. In the embodiment, the safety plug is an aluminum foil.
When the ignition device is used, the ignition device can generate sparks, flames and the like after being started, and the sparks, the flames and the like are utilized to ignite the compressed gas in the containing shell, so that high-pressure gas can be generated; after the high pressure gas is formed in the housing, the pressure in the housing is increased rapidly, so that the high temperature high pressure gas breaks through the safety blocking piece, is ejected from the gas ejection opening, and rapidly enters the first chamber 1111 through the exhaust opening 1211 and the air inlet opening 1113 to push the sealing piston 112 to move.
For ease of understanding, the following is a brief description of the use of the above-described two-piece fire suppression apparatus 100:
(1) when a fire breaks out, the initiating piece is started manually or automatically;
(2) the actuated initiator immediately triggers the gas generant 122 to generate a quantity of high pressure gas within the power vessel 121;
(3) the high pressure gas in the power vessel 121 rapidly enters the first chamber 1111 through the connection pipe 140, such that the pressure in the first chamber 1111 rapidly rises, thereby pushing the sealing piston 112 to move in a direction away from the first chamber 1111, so as to push the fire extinguishing agent 113 in the second chamber 1112 out of the output port 1114 and extinguish the fire in the area of fire.
In order to ensure the safety and reliability of the fire-fighting equipment during use, each part of the fire-fighting equipment needs to be regularly maintained. Because the power container 121 is detachably connected with the fire extinguishing container 111 and the starter 130 is detachably connected with the power container 121, when the split fire extinguishing apparatus 100 needs fire-fighting maintenance, if the fire extinguishing agent 113 needs to be replaced, the maintenance personnel only need to detach and replace the fire extinguishing container 111 from the power container 121; if the components in the starter 130 and the power unit 120 are damaged during use, the damaged components need to be replaced, or the starter 130 or the power container 121 containing the damaged components need to be removed and replaced. Therefore, compared with the prior art in which the whole fire extinguishing apparatus needs to be replaced during fire-fighting maintenance, the split fire extinguishing apparatus 100 can be maintained for fire-fighting by replacing only part of the structure, thereby reducing the fire-fighting maintenance cost.
In some embodiments, the split suppression apparatus 100 further comprises a connection tube 140. One end of the connection pipe 140 is detachably connected to the fire extinguishing container 111 and communicates with the air inlet 1113. The other end of the connection pipe 140 is detachably connected to the power container 121 and communicates with the exhaust port 1211. The connection pipe 140 may be detachably connected to the exhaust 1211 of the power container 121 and the air inlet 1113 of the fire extinguishing container 111 by a pipe joint, a pipe hoop, or some other detachable manner. The connection pipe 140 is provided to separate the fire extinguishing unit 110 from other parts in the divided type fire extinguisher, so that the divided type fire extinguishing apparatus 100 can be conveniently installed in a location where an installation space is narrow or an installation condition is limited. The length of the connecting pipe 140 can be selected according to the field installation requirement and the use requirement of the split type fire extinguishing apparatus 100.
Furthermore, the connection pipe 140 is provided to increase the distance between the fire extinguishing unit 110 and the power unit 120 and the starter 130, thereby facilitating the replacement and maintenance of the fire extinguishing unit 110.
In some embodiments, the initiator is used to trigger the gas generant 122 such that the gas generant 122 produces high temperature, high pressure gas. For example, when the gas generant 122 is a combustible particulate material, the initiator ignites the combustible particulate material to produce a quantity of high temperature, high pressure gas; when the gas generant 122 includes compressed gas, the initiator ignites the compressed gas to produce a quantity of high temperature, high pressure gas.
A partition 1212 is provided in the power container 121 to divide the space inside the power container 121 into a power region 1213 and a cooling region 1214 that communicate with each other. An exhaust port 1211 communicated with the cooling area 1214 is formed in the side wall of the power container 121. The gas generant 122 is received in the power zone 1213.
The power unit 120 also includes a temperature sink 123. The cooling material 123 is accommodated in the cooling zone 1214 and is used for cooling the high-temperature and high-pressure gas generated by the gas generating material 122. Wherein, the cooling member 123 can be a cooling material particle composed of magnesium carbonate or magnesium bicarbonate, and can also be a cooling structure with cooling and heat dissipation functions.
The high-pressure gas generated by the gas generating element 122 is too high in temperature, so that the fire extinguishing agent 113 in the second chamber 1112 is decomposed, the content of the fire extinguishing agent 113 is reduced, and the fire extinguishing effect of the split type fire extinguishing apparatus 100 is affected, and a large amount of toxic and harmful gas is generated after the gas fire extinguishing agent 113 and the aerosol fire extinguishing agent 113 are decomposed in a high-temperature environment, and the toxic and harmful gas may possibly cause damage to disaster victims, rescue personnel and the like on the site. In addition, if the temperature of the high-pressure gas is too high, there is a risk that parts such as the seal piston 112 in the fire extinguishing container 111 are damaged, which affects the reliability of the separate fire extinguishing apparatus 100.
Therefore, in the actual use process, even if the temperature of the high-pressure gas generated by the gas generating element 122 is very high, after the temperature of the high-pressure gas is reduced by the temperature reducing element 123 in the temperature reducing region 1214, the temperature of the high-pressure gas entering the first chamber 1111 is already low when the high-pressure gas contacts the sealing piston 112, and the fire extinguishing agent 113 in the second chamber 1112 is not decomposed to affect the fire extinguishing effect and the safety of the split-type fire extinguishing apparatus 100, and the probability of damaging the components in the fire extinguishing container 111 is also reduced.
When the fire extinguishing agent 113 is a perfluorohexanone fire extinguishing agent, the temperature of the high-temperature and high-pressure gas is very low when the high-temperature and high-pressure gas contacts the sealing piston 112 after being cooled by the cooling member 123, so that the situation that perfluorohexanone in the perfluorohexanone fire extinguishing agent in the second chamber 1112 is cracked is not caused, and the situation that perfluorohexanone in the perfluorohexanone fire extinguishing agent is cracked in the fire extinguishing container 111 is avoided. Therefore, the cooling member 123 makes the probability of generating highly toxic gas by splitting the perfluorohexanone in the perfluorohexanone fire extinguishing agent in the using process lower, and further makes the use safety of the split fire extinguishing apparatus 100 higher.
Specifically, in one embodiment, the cooling member 123 is a cooling material particle. The temperature reducing substance particles are used for absorbing the heat of the high-temperature high-pressure gas contacted with the temperature reducing substance particles. Specifically, the cooling substance particles can be magnesium carbonate particles, magnesium bicarbonate particles and the like. Therefore, the temperature-reducing substance particles absorb heat in the high-temperature and high-pressure gas by changing the form (for example, changing the solid state into the liquid state or the gaseous state) of the temperature-reducing substance particles, so as to achieve the purpose of reducing the temperature of the high-temperature and high-pressure gas.
Specifically, in another embodiment, the cooling member 123 includes a heat dissipation pipe network (not shown) installed in the cooling zone 123 and a cooling liquid (not shown) contained in the heat dissipation pipe network. Specifically, the heat dissipation pipe network is formed by cross connection of a plurality of pipe fittings with good heat dissipation performance, and has the functions of heat dissipation and heat conduction. A plurality of spaces or channels for high-temperature and high-pressure gas to pass through are formed between the heat dissipation mesh pipes. When the high-temperature and high-pressure gas generated by the gas generating element 122 passes through the heat dissipation pipe network, the coolant can quickly take away the heat in the high-temperature and high-pressure gas, so as to achieve the purpose of cooling.
In some embodiments, actuator 130 further comprises a housing (not shown), a temperature sensing element (not shown), a magnet (not shown) capable of generating a magnetic field, and a coil (not shown) electrically connected to the initiator. The housing is detachably mounted to an outer wall of the power container 121 to enable a detachable connection between the initiator 130 and the power container 121. The magnet and the coil are accommodated in the housing. The temperature sensing element is used for triggering the magnet to move in the direction towards the coil when the ambient temperature exceeds a preset threshold value until the coil cuts the magnetic force lines generated by the magnet so as to generate electric pulses on the coil. The initiator is used to trigger the gas generant 122 to generate high pressure gas upon application of an electrical pulse.
That is, when the ambient temperature is higher than the preset threshold, the temperature sensing element triggers the magnet to move, and under the interaction between the magnet and the coil, the coil automatically generates an electric pulse. Therefore, the temperature sensing element can continuously detect the ambient temperature without electric energy, and when the ambient temperature is sensed to be higher than the preset threshold value, the magnet is triggered to move, so that the coil generates electric pulses when the ambient temperature is higher than the preset threshold value.
Therefore, the fire extinguishing apparatus 100 can be normally operated without continuously supplying electric energy from an external power circuit or other power storage devices, and even in the absence of power such as power failure or circuit failure, the fire extinguishing apparatus 100 can continuously detect the ambient temperature and automatically start when the ambient temperature exceeds a preset threshold value, so as to timely and rapidly extinguish fire in a fire area, and therefore the fire extinguishing apparatus 100 has high fire safety.
In addition, in the non-use state, since the inside of the split-type fire extinguishing apparatus 100 does not need to store high-pressure gas or the fire extinguishing agent 113 is compressed in the fire extinguishing container 111 in a high-pressure mode, the pressure in the fire extinguishing container 111 is the same as or close to the external atmospheric pressure, the probability of the fire extinguishing container 111 bursting or the like due to the excessive internal pressure in the non-use state is avoided, and the fire safety is further improved.
Further, in some embodiments, the actuator 130 further includes a moving rod (not shown) and an elastic member (not shown). The magnet is installed on the movable rod. The elastic member is connected with the moving rod and is used for providing an elastic force for driving the moving rod to move along the direction towards the coil. The temperature sensing element is a temperature sensing element capable of clamping the moving rod. The heat sensitive element is used to release the travel bar when the ambient temperature exceeds a preset threshold. The thermosensitive element is made of thermosensitive materials such as fusible alloy, and the physical properties of the thermosensitive element can change along with the change of temperature; the elastic element can be a compression spring, a metal elastic sheet and the like.
When the ambient temperature is lower than the preset threshold value, the temperature sensing element clamps the moving rod by utilizing the structural shape of the temperature sensing element, so that the situation that the moving rod drives the magnet to move when the split type device is in a non-use state can be avoided; when the ambient temperature is higher than the preset threshold value, the structural shape of the temperature sensing element can be immediately changed to loosen the moving rod, and the moving rod rapidly penetrates through the coil under the action of elastic force provided by the elastic piece, so that the coil can cut magnetic force lines of a magnetic field generated by the magnet, and electric pulses are automatically generated on the coil.
Further, in some embodiments, the temperature-sensitive element is removably mounted to the housing. The temperature sensing element may be mounted outside the housing or may be mounted inside the housing. The temperature sensing element is arranged in a detachable installation mode so as to be convenient to detach and install. When the temperature sensing element is damaged, maintenance personnel only need to detach the temperature sensing element from the shell, and do not need to replace the whole starter 130 or even the whole split type fire extinguishing device 100, so that the fire protection maintenance cost of the split type fire extinguishing device 100 is further reduced.
In some embodiments, the fire suppression unit 100 further comprises a sealing plate (not shown). The closing plate is disposed at the output port 1114, and is used to close the output port 1114 and automatically conduct when the sealing piston 112 moves in a direction toward the output port 1114. In this embodiment, the sealing plate is an aluminum foil.
In use, the sealing piston 112 is pushed by the high-pressure gas generated by the gas generating member 122 to move rapidly in a direction toward the output port 1114, so as to instantaneously increase the pressure in the second chamber 1112, and thus the fire extinguishing agent 113 in the second chamber 1112 breaks through the sealing plate and is sprayed out from the output port 1114, thereby extinguishing a fire at a fire location. Therefore, the sealing plate can seal the fire extinguishing agent 113 in the second chamber 1112, so as to reduce the probability of the fire extinguishing agent 113 leaking from the fire extinguishing device 100, and the fire extinguishing device 100 is more convenient to use.
In some embodiments, the two-piece fire suppression apparatus 100 further includes a connection structure 150. The connection structure 150 is connected to the fire extinguishing container 111 and communicates with the output port 1114. The end of the attachment structure 150 remote from the output 1114 is in communication with a spray head (not shown) or a fire suppression line (not shown). Wherein, the spray head or the fire extinguishing pipeline sprays the fire extinguishing agent 113 sprayed by the split type fire extinguishing apparatus 100 to the fire flame or the protected piece. Therefore, the connection structure 150 is provided, so that the connection of the nozzle and the fire extinguishing pipeline on the split type fire extinguishing apparatus 100 is more convenient and simpler.
Specifically, the connection structure 150 is directly connected to the nozzle or the fire extinguishing pipe by means of screwing, clamping, bonding, or the like, or may be connected to the nozzle or the fire extinguishing pipe by means of an auxiliary structure such as a pipe joint, a pipe hoop, or the like.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within 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.
