Furthermore, the drawings are not 1: 1, and the relative dimensions of the various elements in the figures are drawn for illustration only and not necessarily to true scale.
As described in the background art, since a conventional pressure storage type fire extinguishing apparatus stores high-pressure gas therein or compresses a fire extinguishing agent in a fire extinguishing container by using high pressure, the pressure in the fire extinguishing container is very high in both a use state and a non-use state, and there is a risk of a situation such as burst of the fire extinguishing container, which poses a great threat to the safety of surrounding equipment, personnel safety, and the like. Based on this, the applicant proposes a non-pressure-storage type fire extinguishing apparatus which can ensure that the internal pressure and the potential safety hazard are low.
Fig. 1 shows a schematic diagram of a non-stored pressure 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 non-stored pressure fire suppression apparatus 100 according to the preferred embodiment of the present invention includes a fire suppression container 110, a gas generator 130, a sealing piston 120, an initiator 140, a pressure relief member 180, and a fire suppressant 160.
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) and a pressure relief port (not shown) communicating with the second chamber 112.
The fire extinguishing agent 160 is contained within the second chamber 112. The fire extinguishing agent 160 may be a gas fire extinguishing agent or an aerosol fire extinguishing agent. Specifically, in this embodiment, the fire extinguishing agent 160 is a perfluorohexanone fire extinguishing agent. The perfluorohexanone fire extinguishing agent can be fire extinguishing agent 160 comprising perfluorohexanone alone or fire extinguishing agent 160 comprising 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. The perfluoro hexanone has the advantages of high environmental protection performance, low corrosivity, easy cleaning and the like, so the fire extinguishing agent 160 is set as the perfluoro hexanone fire extinguishing agent, which not only can improve the fire extinguishing effect of the non-stored pressure type fire extinguishing apparatus 100, but also can make the non-stored pressure type fire extinguishing apparatus 100 more environment-friendly, and is beneficial to the field cleaning after the fire rescue.
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 and shell 131 can be for connecting the mosaic structure in order to constitute through modes such as welding, joint, spiro union, 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. Wherein, the cylinder structure can be a cylinder structure, a flat cylinder structure and the like. The housing 131 and the fire extinguisher container are integrally formed, so that not only the connection between the housing 131 and the fire extinguishing container 110 is stable, but also the manufacturing process of the non-pressure storage type fire extinguishing apparatus 100 is simplified. Furthermore, 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 non-stored pressure type fire extinguishing apparatus 100, so that the non-stored pressure type fire extinguishing apparatus 100 can be installed or used in a narrow space.
The initiation member 140 is coupled to the gas generant member 132 and is configured to trigger the gas generant member 132 to generate high pressure gas. 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 member 140.
Specifically, in one embodiment, the gas generant member 132 is a combustible substance, such as gunpowder or the like. The initiator 140 is a pyrotechnic structure such as a friction ignition device, an electronic ignition device, or the like. The initiator 140 is used to ignite the gas generant 132 to produce high pressure gas. In use, the initiator 140 is activated to generate a spark, flame, etc. that ignites the gas generant 132 to generate a large amount of high temperature, high pressure gas.
In another embodiment, the initiation member 140 is a pyrotechnic 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 140 is used to ignite the compressed gas to form a high pressure gas. A gas injection port (not shown) is formed at a portion of the side wall of the housing case facing the side of the sealing piston. 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 in use, the initiating piece 140 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-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.
The pressure relief member 180 includes a pressure relief body. The pressure relief body is installed on the outer wall of the fire extinguishing container 110 and is communicated with the pressure relief port. The pressure relief main body is used for controlling the opening of the pressure relief opening when the pressure value in the second chamber is larger than a preset threshold value. When the pressure value in the second chamber is larger than the preset threshold, the pressure relief main body can open the pressure relief opening under the action of pressure (the pressure value must be larger than the preset threshold), and the pressure relief main body can also be controlled to open the pressure relief opening through the control detection device.
Specifically, the pressure relief member 180 also includes a pressure sensing member. The pressure detector is used for detecting the pressure information in the second chamber 112. The pressure relief main body is used for controlling the opening of the pressure relief opening according to the pressure information. Wherein, the pressure detection piece can be a pressure gauge, a pressure sensor and the like; the pressure relief member 180 may be a safety valve, a pressure relief valve, or other types of automatic pressure relief structures.
Specifically, when the pressure detecting element detects that the pressure value in the second chamber 112 is less than or equal to the preset pressure threshold, the pressure relief port is in a normally closed state, so as to avoid the occurrence of situations such as leakage of the fire extinguishing agent 160 in the second chamber 112; when the pressure detection piece detects that the pressure value in the second chamber 112 exceeds the preset pressure threshold, the pressure relief main body opens the pressure relief opening immediately to reduce the pressure in the second chamber 112, thereby achieving the purpose of pressure relief.
For ease of understanding, the following is a brief description of the use of the above-described non-stored pressure fire suppression apparatus 100:
(1) in the event of a fire, initiating element 140 is activated either manually or automatically;
(2) the actuated initiator 140 immediately triggers the gas generant 132 to generate a quantity of high pressure gas within the housing 131;
(3) 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 160 in the second chamber 112 out of the output port and to extinguish the fire to the area of fire.
Accordingly, in the non-use state, since the non-stored pressure type fire extinguishing apparatus 100 does not store high pressure gas therein or compresses the fire extinguishing agent 160 in the form of high pressure in the fire extinguishing container 110, the pressure in the fire extinguishing container 110 is equal to or close to the atmospheric pressure outside, thereby preventing the fire extinguishing container 110 from being burst due to an excessive internal pressure thereof in the non-use state. Further, in the using process of the non-pressure storage type fire extinguishing apparatus 100, if the output port is blocked, the pressure in the second chamber will increase rapidly, and until the pressure value in the second chamber is greater than the preset threshold value, the pressure relief main body controls the pressure relief port to open, so as to achieve the purpose of pressure relief, thereby reducing the probability of the conditions of explosion and cracking caused by the overlarge pressure in the second chamber 112 in the using process of the fire extinguishing container 110. Therefore, the non-stored pressure type fire extinguishing apparatus 100 has high safety performance.
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, high pressure gas generated by gas generant 132 within housing 131 enters buffer region 1111 and then enters power region 1112 and pushes upon seal 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 preventing the non-stored pressure type fire extinguishing apparatus 100 from being damaged due to the excessive pressure of the high-pressure gas, and the like, not only prolonging the service life of the non-stored pressure type fire extinguishing apparatus 100, but also further improving the safety performance of the non-stored pressure type fire extinguishing apparatus 100.
In some embodiments, the gas generant 132 is configured to generate high temperature, high pressure gas upon activation of the initiator 140. For example, when the gas generant portion 132 is a combustible particulate material, the gas generant portion 132 can generate a substantial amount of high temperature, high pressure gas upon actuation of the initiator 140. The non-stored pressure fire suppression apparatus 100 also includes a temperature sink 150. The cooling member 150 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 150 may be a cooling material particle made of magnesium carbonate or magnesium bicarbonate, or a cooling structure having a cooling and heat dissipating function.
If the temperature of the high-pressure gas generated by the gas generating element 132 is too high, the fire extinguishing agent 160 in the second chamber 112 will be decomposed, which not only reduces the content of the fire extinguishing agent 160 and thus affects the fire extinguishing effect of the stored-pressure fire extinguishing apparatus, but also generates a large amount of toxic and harmful gas after the decomposition of the gas fire extinguishing agent 160 and the aerosol fire extinguishing agent 160 in the high-temperature environment, which may be harmful to the disaster-stricken, rescue personnel, etc. in the field. If the temperature of the high-pressure gas is too high, parts such as the seal piston 120 in the fire extinguishing container 110 may be damaged, which affects the reliability of the non-stored-pressure type 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 150 in the first chamber 111, and the fire extinguishing agent 160 in the second chamber 112 is not decomposed to affect the fire extinguishing effect and safety of the above-mentioned non-stored-pressure type 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 160 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 150, 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 non-pressure storage type fire extinguishing device 100 is avoided. Therefore, the cooling member 150 is disposed to make the probability of generating highly toxic gas by cracking the perfluorohexanone in the perfluorohexanone fire extinguishing agent during the use process lower, and further make the safety of the non-stored pressure type fire extinguishing apparatus 100 higher.
When the first chamber 111 includes the buffer zone 1111 and the power zone 1112, the cooling member 150 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 to be contacted with the cooling element 150, 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 150 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 150 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 unpressurized fire suppression device 100 further includes a control circuit (not shown) and an activation button (not shown) electrically connected to the control circuit. The start button is used for receiving pressing operation and generating a preset control instruction. The control circuit is electrically connected to the initiating element 140 and is used for controlling the initiating element 140 to start according to a preset control command. In the event of a fire, the field personnel presses the activation button to activate the initiation member 140, thereby triggering the gas generant member 132; the gas generating member 132 generates a large amount of high-pressure gas to push the sealing piston 120 to move when triggered, so as to spray the fire extinguishing agent 160 to the fire area for fire extinguishing. Thus, the non-stored pressure fire extinguishing apparatus 100 is manually activated by the installation of the activation button and the control circuit.
In some embodiments, the unpressurized 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 nozzle or the fire extinguishing pipe sprays the fire extinguishing agent 160 sprayed from the non-stored pressure type fire extinguishing apparatus 100 to the place where the fire is on fire or to the protected member. Therefore, the connection structure 170 makes the connection of the nozzle and the fire extinguishing pipe to the non-stored pressure type fire extinguishing apparatus 100 more convenient and simpler.
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.
It should be noted that, in the actual use process, if at least one of the output port, the nozzle, and the fire extinguishing pipeline is blocked, the pressure value in the second chamber 112 in the non-stored pressure type fire extinguishing apparatus 100 after being started will directly rise, and at this time, the pressure relief member 180 is arranged, so that the excess pressure can be discharged to the outside through the pressure relief port, and it is ensured that the pressure value in the second chamber 112 is within the safety range.
Referring to fig. 1 again, based on the above non-stored pressure fire extinguishing apparatus 100, the present invention further provides a fire extinguishing system (not shown). The fire fighting system includes a non-stored pressure type fire extinguishing apparatus 100, a fire detecting member (not shown), and a control main unit (not shown).
The fire detection member is used for monitoring environmental information of a preset area. Specifically, the fire detection member includes at least one of a temperature detector, a flame detector, a smoke detector, and a smoke temperature composite detector. The control circuit is electrically connected with the initiating piece 140 and controls the starting of the initiating piece 140 according to the environment information. Wherein the environmental information includes at least one of temperature information, smoke information, and flame information. Therefore, the fire detection member includes at least one of a temperature detector, a flame detector, a smoke detector, and a smoke temperature composite detector.
When the fire detection part monitors that the temperature in the preset area is higher than a preset temperature threshold value, the smoke concentration is higher than a preset concentration threshold value, at least one of open flame, a special infrared band and a special ultraviolet band occurs, the control circuit immediately controls the initiation part 140 to be started, so that the gas generation part 132 generates a large amount of high-pressure gas to push the sealing piston 120 to move, and the fire extinguishing agent 160 is sprayed to the fire area to realize fire fighting. Therefore, the fire extinguishing system can realize an intelligent fire extinguishing function. Further, because of the excellent performance of the above-described non-stored pressure fire extinguishing apparatus 100, the safety performance of a fire extinguishing system including the non-stored pressure fire extinguishing apparatus 100 is also high.
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.
