Fig. 1 shows a schematic diagram of a mechanically actuated fire suppression 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. The mechanically activated fire suppression apparatus 100 of the preferred embodiment of the present invention includes a fire suppression container 110, a sealing piston 120, a gas generator 130, an initiator 140, and a fire suppressant 150.
The sealing piston 120 is accommodated in the fire extinguishing container 110 and slidably and sealingly contacts the inner wall of the fire extinguishing container 110 to divide the space in the fire extinguishing container 110 into the first chamber 111 and the second chamber 112. The side wall of the fire extinguishing container 110 is opened with an outlet (not shown) communicating with the second chamber 112.
The fire suppressant 150 is contained within the second chamber 112. The fire extinguishing agent 150 may be a gaseous fire extinguishing agent 150, or an aerosol fire extinguishing agent 150. Specifically in this embodiment, fire extinguishing agent 150 is a perfluorohexanone fire extinguishing agent 150. The perfluorohexanone fire-extinguishing agent 150 may be a fire-extinguishing agent 150 containing only perfluorohexanone, or may be a fire-extinguishing agent 150 containing perfluorohexanone. The perfluorohexanone fire extinguishing agent 150 is vaporized at the moment of contact with the flames of the fire scene or the protected piece which is about to catch fire, so as to achieve the purpose of temperature reduction and fire extinguishing. And perfluorohexanone has advantages such as environmental protection performance is high, corrosivity is low, easily clearance, so set up fire extinguishing agent 150 as perfluorohexanone fire extinguishing agent 150, not only can improve the fire extinguishing effect of above-mentioned fire extinguishing apparatus 100 that mechanical type starts, but also make above-mentioned fire extinguishing apparatus 100 that mechanical type starts more green, still be favorable to the scene clearance after the conflagration rescue in addition.
The gas generator 130 includes a housing 131 and a gas generating element 132 housed in the housing 131. The housing 131 is disposed at an outer wall of the fire extinguishing container 110 and communicates with the first chamber 111. Wherein, extinguishing container 110 is hollow shell structure, and extinguishing container 110 can be connected through modes such as welding, joint, spiro union with shell 131 to constitute mosaic structure, also can be the overall structure that integrated into one piece formed.
Specifically, the housing 131 and the fire extinguishing container 110 are formed as an integrally formed cylindrical structure. The housing 131 and the fire extinguishing container 110 are integrally formed, so that the connection between the housing 131 and the fire extinguishing container 110 is stable, and the machining process of the mechanically-started fire extinguishing apparatus 100 is simplified. Moreover, the casing 131 and the fire extinguishing container 110 are integrally formed into a cylindrical structure, which is beneficial to reducing the volume of the mechanically-started fire extinguishing apparatus 100, so that the mechanically-started fire extinguishing apparatus 100 can be installed or used in a narrow space.
Specifically, the actuator 140 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 temperature 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 temperature threshold, the temperature sensing element clamps the moving rod by using the structural shape of the temperature sensing element, so that the situation that the moving rod drives the magnet to move when the mechanically started fire extinguishing device 100 is in a non-use state can be avoided; when the ambient temperature is higher than the preset temperature threshold, 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.
More specifically, the actuator 140 further includes a housing (not shown) mounted to an outer wall of the housing 131. The magnet, the coil, the moving rod and the elastic piece are all arranged in the shell. Therefore, the shell mainly plays a role in connection and protection, so that the magnet, the coil, the moving rod and the elastic piece are more convenient to install, and the condition that external water, dust, impurities and the like damage components in the shell can be avoided, so that the service life and the service reliability of the starter 140 are improved.
The initiator is used to trigger the gas generant 132 under the application of an electrical pulse to produce high pressure gas. Thus, the initiator is an electrically powered element. The gas generating member 132 may generate high pressure gas by combustion, chemical reaction, or the like. The gas generant member 132 generates a quantity of high pressure gas upon actuation of the initiator. The coil is very short in time for providing the electric energy for the initiating element, the electric energy is provided only when the coil can cut the magnetic lines of force of the magnetic field generated by the magnet, and once the magnet penetrates out of the coil and the coil cannot cut the magnetic lines of force generated by the magnet, the electric pulse is not generated on the coil.
Specifically, in one embodiment, the gas generant member 132 is a combustible substance, such as gunpowder or the like. The initiating piece is an electric pulse ignition structure, such as an electronic igniter, a resistance wire capable of generating high temperature under the action of electric pulse, a heating wire and the like. The initiator is used to ignite the gas generant 132 with an electrical pulse to produce high pressure gas. In use, after the electrical pulse generated by the coil is transmitted to the initiator, the initiator generates a spark, flame, high temperature, etc., and the gas generating member 132 is ignited by the spark, flame, temperature, etc., thereby generating a large amount of high-temperature, high-pressure gas.
In another embodiment, the initiating element is an electric pulse ignition structure. The gas generating member 132 includes a housing case (not shown), a rupture disk (not shown), and a compressed gas (not shown). The initiator is used to ignite the compressed gas under the action of the electrical pulse to form high pressure gas. A gas injection port (not shown) is formed at a portion of the sidewall of the housing case facing the side of the sealing piston 120. The safety blocking piece is arranged at the gas jet orifice and used for blocking the gas jet orifice and automatically conducting when high-temperature and high-pressure gas is formed in the containing shell. In the embodiment, the safety plug is an aluminum foil.
When the gas ignition device is used, after electric pulses generated by the coil are transmitted to the initiating piece, the initiating piece can generate sparks, flames, high temperature and the like, and the compressed gas in the containing shell is ignited by the sparks, the flames, the high temperature and the like, so that high-temperature and high-pressure gas can be generated; after high-temperature and high-pressure gas is formed in the containing shell, the pressure in the containing shell is increased rapidly, so that the high-temperature and high-pressure gas breaks through the safety blocking piece and is sprayed out from the gas spraying opening to push the sealing piston 120 to move.
For ease of understanding, the following is a brief description of the use of the above-described mechanically-actuated fire suppression apparatus 100:
(1) when the ambient temperature around the fire extinguishing device is higher than a preset temperature threshold (at the moment, a fire is about to occur or occurs), the temperature sensing element is influenced by the temperature, and the structural shape of the temperature sensing element is changed to loosen the movable rod;
(2) the moving rod moves along the direction towards the coil immediately under the action of the elastic force provided by the elastic piece until the magnet passes through the coil, and the coil cuts the magnetic force lines of the magnetic field generated by the magnet so as to generate electric pulses on the coil;
(3) the initiation member triggers the gas generant member 132 to generate a quantity of high pressure gas within the housing 131 immediately after the electrical pulse on the coil is delivered to the initiation member;
(4) the high pressure gas in the housing 131 rapidly enters the first chamber 111 such that the pressure in the first chamber 111 rapidly rises, thereby pushing the sealing piston 120 to move in a direction away from the first chamber 111 to push the fire suppressant 150 in the second chamber 112 out of the output port and to extinguish the fire in the area of fire.
Therefore, in the actual use process, the mechanically activated fire extinguishing apparatus 100 can operate normally without continuously supplying electric energy from an external circuit or other power storage devices, and even in the absence of power, such as power failure or circuit failure, the mechanically activated fire extinguishing apparatus 100 can continuously detect the ambient temperature and automatically activate when the ambient temperature exceeds a preset temperature threshold value, so as to timely and rapidly extinguish fire in an area on fire, and therefore the mechanically activated fire extinguishing apparatus 100 has high fire safety.
In addition, in the non-use state, since the fire extinguishing apparatus 100 mechanically activated as described above does not store high-pressure gas therein, or compresses the fire extinguishing agent 150 in the form of high pressure in the fire extinguishing container 110, the pressure in the fire extinguishing container 110 is the same as or close to the outside atmospheric pressure, thereby preventing the fire extinguishing container 110 from being burst due to an excessive internal pressure thereof in the non-use state, and further improving the fire safety.
In some embodiments, a partition 113 is disposed within the first chamber 111 to divide the first chamber 111 into a buffer zone 1111 and a power zone 1112 that are in communication with each other. The housing 131 communicates with the buffer 1111. Therefore, the buffer zone 1111 and the housing 131 are located on the same side of the power zone 1112, both on the side of the power zone 1112 facing away from the second chamber 112. Thus, the high pressure gas generated by gas-generating component 132 in housing 131 first enters buffer region 1111 for buffer depressurization and then enters power region 1112 and pushes sealing piston 120. The buffer zone 1111 buffers the high-pressure gas generated by the gas generating member 132 to reduce the pressure of the high-pressure gas, thereby avoiding the occurrence of the damage of the mechanically started fire extinguishing apparatus 100 due to the excessive pressure of the high-pressure gas, and the like, not only prolonging the service life of the mechanically started fire extinguishing apparatus 100, but also further improving the safety performance of the mechanically started fire extinguishing apparatus 100.
In some embodiments, the initiator is configured to trigger the gas generant member 132 in response to an electrical pulse to cause the gas generant member 132 to produce high temperature, high pressure gas. For example, when the gas generant member 132 is a combustible particulate material, the gas generant member 132 can generate a substantial amount of high temperature, high pressure gas upon actuation of the initiator member; when the gas generant member 132 includes compressed gas, the initiator ignites the compressed gas under an electrical pulse to produce a quantity of high temperature, high pressure gas. The mechanically activated fire suppression apparatus 100 also includes a temperature reduction member 160. The cooling member 160 is accommodated in the first chamber 111 and is used for cooling the high-temperature and high-pressure gas generated by the gas generating member 132. The cooling member 160 may be a cooling material particle made of magnesium carbonate or magnesium bicarbonate, or a cooling structure with cooling and heat dissipation functions.
The high-pressure gas generated by the gas generating element 132 is at a too high temperature, which may decompose the fire extinguishing agent 150 in the second chamber 112, thereby not only reducing the content of the fire extinguishing agent 150 and affecting the fire extinguishing effect of the mechanically activated fire extinguishing apparatus 100, but also generating a large amount of toxic and harmful gases after the decomposition of the gaseous fire extinguishing agent 150 and the aerosol fire extinguishing agent 150 in a high-temperature environment, which may possibly cause damage to the disaster-stricken, rescue personnel, etc. in the field. In addition, if the temperature of the high-pressure gas is too high, there is a risk that components such as the seal piston 120 in the fire extinguishing container 110 may be damaged, which affects the reliability of the mechanically activated fire extinguishing apparatus 100.
Therefore, in practical use, even if the temperature of the high-pressure gas generated by the gas generating member 132 is very high, the temperature of the high-pressure gas contacting the sealing piston 120 is already low after the temperature is reduced by the temperature reducing member 160 in the first chamber 111, and the fire extinguishing agent 150 in the second chamber 112 is not decomposed to affect the fire extinguishing effect and safety of the mechanically actuated fire extinguishing apparatus 100, and the probability of damage to the components in the fire extinguishing container 110 is also reduced.
When the fire extinguishing agent 150 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 120 after being cooled by the cooling member 160, so that the situation that perfluorohexanone in the perfluorohexanone fire extinguishing agent in the second chamber 112 is cracked is not caused, and the situation that perfluorohexanone in the perfluorohexanone fire extinguishing agent is cracked in the fire extinguishing container 110 is avoided. Therefore, the cooling member 160 is disposed, so that the probability of generating highly toxic gas by cracking the perfluorohexanone in the perfluorohexanone fire extinguishing agent during the use process is low, and the use safety of the mechanically-started fire extinguishing apparatus 100 is further improved.
When the first chamber 111 includes the buffer zone 1111 and the power zone 1112, the cooling member 160 is accommodated in the power zone 1112. When the gas generator is used, high-temperature and high-pressure gas generated by the gas generating element 132 firstly enters the buffer region 1111 to be buffered and depressurized, and then enters the power region 1112 from the buffer region 1111 and contacts the cooling element 160, so that the purpose of reducing the temperature and the pressure of the high-pressure gas is achieved.
Specifically, in one embodiment, the cooling member 160 is a particulate cooling material. 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.
In another embodiment, the cooling member 160 includes a heat dissipating pipe network (not shown) installed in the first chamber 111 and a cooling liquid (not shown) contained in the heat dissipating 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 high-pressure gas generated by the gas generating element 132 passes through the heat dissipation pipe network, the cooling liquid can quickly take away the heat in the high-temperature high-pressure gas, so as to achieve the purpose of cooling.
In some embodiments, the mechanically activated fire suppression apparatus 100 further includes a connection structure 170. The connection structure 170 is connected to the fire extinguishing container 110 and communicates with the output port. The end of the connecting structure 170 remote from the outlet port communicates with a spray head (not shown) or a fire suppression line (not shown). Wherein the spray head or the fire extinguishing line sprays the fire extinguishing agent 150 sprayed from the mechanically activated fire extinguishing apparatus 100 onto the site of the fire flames or onto the protected member. Thus, the connection structure 170 allows the nozzle and the fire extinguishing line to be connected to the mechanically activated fire extinguishing apparatus 100 more conveniently and simply.
Specifically, the connection structure 170 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. Therefore, the protection scope of the present invention should be subject to the appended claims.
