Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing equipment, and more particularly to a starting device and a fire extinguishing equipment comprising the starting device. Background Art

[0002] In order to spray out the fire extinguishing agent to extinguish the fire, the pressure-stored fire extinguishing equipment needs to fill a certain amount of pressurized gas into the container. The pressure of the gas generally ranges from 1.2MPa to 20MPa. Since the entire fire extinguishing equipment is composed of many components such as the fire extinguishing agent storage container, container valve, pressure gauge, fire extinguishing agent injection port, signal feedback device, etc., and the pressure-stored fire extinguishing equipment is stored under pressure for a long time, the joints of these components become pressure leakage points. Once the fire extinguishing equipment leaks pressure, the fire extinguishing agent cannot be sprayed out normally. Therefore, the pressure-stored fire extinguishing equipment needs to be maintained and pressurized regularly. If the maintenance is not timely, a fire occurs at this time, especially in public transportation, and maintenance and pressurization need to be driven to the station. If the pressure is released during driving and the fire cannot be extinguished when it happens, it will cause mass deaths and injuries, and the consequences are very serious.

[0050] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0051] Embodiment 1

[0052] like Figure 1 As shown, an embodiment of the present invention provides a starting device 100. The starting device 100 comprises: a housing 1, a gas generating device 2 and a triggering device 3.

[0053] Specifically, the housing 1 is provided with at least one nozzle 1513, and a sealed cavity 1113 is provided inside the housing 1. Figure 2As shown, the gas producing device 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21. The sealed container 21 is connected to the shell 1. The triggering device 3 is located outside the gas producing device 2. The triggering device 3 includes a striker 31 and an initiator 32. The striker 31 is arranged corresponding to the sealed container 21, and is used to puncture the sealed container 21 so that the driving medium 22 sprays out of the sealed container 21 and forms a gas. One end of the initiator 32 is located in the sealed cavity 1113, and the other end of the initiator 32 extends through the shell 1 to the outside of the shell 1, and the initiator 32 is used to increase the air pressure in the sealed cavity 1113. The sealed cavity 1113 is arranged corresponding to the striker 31, and is used to directly or indirectly drive the striker 31 to move in a direction close to the sealed container 21 by utilizing the increased air pressure, so that the striker 31 punctures the sealed container 21.

[0054] The starting device 100 provided in the embodiment of the present invention can encapsulate the driving medium 22 in an integrated sealed container 21, and can open the sealed container 21 through the triggering device 3 when fire extinguishing is required, so that the driving medium 22 can be ejected out of the sealed container 21 and form a gas that can drive the fire extinguishing agent 220 to be ejected, and the gas can enter the fire extinguishing agent storage container 210 to quickly increase the pressure of the fire extinguishing agent storage container 210, thereby causing the fire extinguishing agent 220 to be ejected under the action of pressure to extinguish the fire. In this way, the fire extinguishing agent 220 does not need to be stored under pressure, thereby fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing equipment, which not only saves the maintenance cost of regular pressurization, but also improves the reliability of the fire extinguishing equipment 200.

[0055] Specifically, the starting device 100 includes a housing 1, a gas generating device 2 and a triggering device 3. The housing 1 is provided with at least one nozzle 1513, and the nozzle 1513 is configured to be able to communicate with the fire extinguishing agent storage container 210, so that the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 can at least be ejected through the nozzle 1513 of the starting device 100. The number of nozzles 1513 can be one or more, and multiple nozzles 1513 are conducive to improving the fire extinguishing efficiency.

[0056] like Figure 2 As shown, the gas generating device 2 is a non-explosive device, specifically including a sealed container 21 and a driving medium 22. The sealed container 21 is an integrated structure, and the driving medium 22 is stored in the sealed container 21. When a fire occurs and needs to be extinguished, the sealed container 21 can be opened by the triggering device 3. When the sealed container 21 is opened, the pressure is quickly released, so that the driving medium 22 is ejected in the form of gas, thereby quickly increasing the gas pressure in the fire extinguishing agent storage container 210, and driving the fire extinguishing agent 220 to eject the fire.

[0057] In this way, the fire extinguishing agent 220 does not need to be stored under pressure, but can be sprayed out by quickly pressurizing it through the gas production device 2 when in use, thereby solving the problem that the existing pressure storage fire extinguishing equipment 200 cannot normally spray the fire extinguishing agent 220 due to pressure leakage, and also saves the maintenance cost of regular pressurization, and can also save the pressure gauge.

[0058] The sealed container 21 of the gas production device 2 is an integrated structure, a sealed whole, and a complete component, without sealing rings, sealants, sealing covers, sealing bolts and other structures, and can be stored independently, such as Figure 2 As shown, there is no pressure leakage problem, and the driving medium 22 can be stably sealed in the sealed container 21 without leakage. The shape of the sealed container 21 is not limited, for example, the cross section of the sealed container 21 can be circular, elliptical, rectangular, square, triangular, etc. The sealed container 21 can be a metal container.

[0059] The amount of gas ejected by the gas producing device 2 can be more or less, and the ejection time can be long or short, which can be reasonably selected according to the amount of the driving medium 22.

[0060] In addition, the existing non-pressure storage fire extinguishing equipment places the triggering device 3 inside the gas producing device 2, and uses electrical or thermal triggering to trigger the gas producing device 2 to spray gas. Since the gas producing device 2 used in the existing non-pressure storage fire extinguishing equipment is a pyrotechnic, when the triggering device 3 triggers the gas producing device 2, a temperature of hundreds of degrees Celsius is instantly generated. Gas will explode when it encounters high temperature, so it cannot be used in gas fire extinguishing equipment and can only be used in dry powder fire extinguishing equipment. The starting device 100 provided in this scheme places the triggering device 3 outside the gas producing device 2, and triggers the gas producing device 2 to produce gas by opening the sealed container 21 to release the pressure of the sealed container 21. Therefore, it can be used not only in dry powder fire extinguishing equipment, but also in gas fire extinguishing equipment and liquid fire extinguishing equipment, thereby greatly expanding the scope of non-pressure storage fire extinguishing equipment and solving the pressure relief problem that has existed in the field of pressure storage fire extinguishing equipment for many years.

[0061] In addition, compared with the existing non-pressure storage type dry powder fire extinguishing equipment, the use of the starting device 100 of this solution can avoid the occurrence of dry powder explosion caused by improper ignition, thereby avoiding the safety hazard caused by the explosion of the fire extinguishing equipment 200 itself. Compared with the existing pressure storage type gas fire extinguishing equipment, the use of the starting device 100 of this solution can convert the pressure storage type gas fire extinguishing equipment into a non-pressure storage type gas fire extinguishing equipment, fundamentally solving the pressure leakage problem of the gas fire extinguishing equipment and improving the fire extinguishing reliability of the gas fire extinguishing equipment.

[0062] Of course, the starting device provided in the embodiment of the present invention can not only be used for fire extinguishing equipment, but can also be widely used in pressurized equipment (with pressurized containers) in various fields of the national economy such as energy, transportation, metallurgy, electricity, and communications. It can transform existing pressurized equipment into non-pressure storage equipment, thereby solving the pressure relief problem that has plagued the industry for many years and providing effective protection for protecting national property and the safety of the people.

[0063] When the starting device 100 is used for other equipment, the nozzle 1513 is used to spray out the substances in the container of other equipment, and the driving medium 22 in the gas generating device 2 sprays out the sealed container 21 to form a gas for driving the substances in the container of other equipment to be sprayed out.

[0064] like Figure 1 As shown, the triggering device 3 includes a striker 31 and an initiator 32. The initiator 32 is used to drive the striker 31 to move. The striker 31 can use the tip portion to quickly pierce the sealed container 21 without generating sparks, is safe to use, and has high opening efficiency.

[0065] Further, if Figure 1 As shown, a sealed cavity 1113 is provided in the housing 1, and one end of the initiator 32 is located in the sealed cavity 1113. When the end of the initiator 32 located outside the sealed cavity 1113 is triggered, the initiator 32 can cause the air pressure in the sealed cavity 1113 to increase, and the increased air pressure in the sealed cavity 1113 can directly or indirectly act on the striker 31, thereby directly or indirectly driving the striker 31 to move, so that the striker 31 pierces the sealed container 21. In this way, it is avoided that the initiator 32 is directly inserted into the sealed container 21 to cause the gas generating device 2 to generate gas by initiating the combustion or explosion of the driving medium 22, thereby avoiding the use of explosives as the gas generating device 2.

[0066] Of course, the triggering device 3 is not limited to the above solution. For example, the triggering device may also include a cutter and a motor, the motor drives the cutter to move, so that the cutter cuts the sealed container and the sealed container is opened; or the triggering device may also include a small electric drill, and the sealed container is opened by the electric drill.

[0067] In an illustrative embodiment, Figure 1 As shown, a piston 16 is provided in the housing 1. The piston 16 is slidably matched with the housing 1 and forms a sealed chamber 1113 with the housing 1. The striker 31 is fixedly connected to the piston 16. The initiator 32 is used to increase the air pressure in the sealed chamber 1113 to drive the piston 16 to drive the striker 31 to move toward the direction close to the sealed container 21.

[0068] In this embodiment, the trigger 32 is specifically used to increase the air pressure in the sealed chamber 1113, and then use the increased air pressure to drive the piston 16 to move. Since the piston 16 is fixedly connected to the striker 31, the piston 16 can drive the striker 31 to move synchronously. This is equivalent to using the increased air pressure in the sealed chamber 1113 to indirectly drive the striker 31 to move in a direction close to the sealed container 21.

[0069] Of course, when the striker 31 and the shell 1 enclose a sealed cavity 1113 , the increased air pressure in the sealed cavity 1113 can be used to directly drive the striker 31 to move toward the sealed container 21 .

[0070] Compared with directly driving the striker 31 to move, using the piston 16 to drive the striker 31 to move is beneficial to simplifying the structure of the striker 31 and improving the sealing performance of the sealing chamber 1113.

[0071] Among them, at least one sealing ring can be sleeved between the piston 16 and the housing 1 to further improve the sealing performance of the sealing chamber 1113. Furthermore, a sealing groove for installing the sealing ring can be correspondingly provided on the outer side wall of the piston 16.

[0072] The striker 31 and the piston 16 can be fixedly connected by interference fit, overmolding or the like.

[0073] In one exemplary embodiment, the initiator 32 comprises an electrical initiator. Figure 1 As shown, the electric initiator includes a resistor 321 and a connecting wire 322 connected to the resistor 321 . The resistor 321 is located in the sealed cavity 1113 , and the connecting wire 322 passes through the housing 1 and extends to the outside of the housing 1 .

[0074] In another exemplary embodiment (not shown), the initiator 32 comprises a thermal initiator.

[0075] In yet another exemplary embodiment (not shown in the figure), the initiator 32 includes both the above-mentioned electrical initiator and the above-mentioned thermal initiator.

[0076] The initiator 32 can be an electric initiator. By connecting a power source, the resistor 321 heats up, causing the air pressure in the sealed chamber 1113 to increase, thereby inducing the striker 31 to move and open the sealed container 21. The electric initiator has three indicators: starting current, safety current, and resistance 321 value. These three indicators satisfy the following relationship: the safety current is less than the starting current, and within the safety current indicator, the resistor 321 must not heat up after being powered on for five minutes; when the current reaches or exceeds the starting current, the resistor 321 heats up; the smaller the resistance 321 value, the greater the current, and vice versa, the greater the resistance 321 value, the smaller the current; the safety current, starting current, and resistance 321 value can all be set as needed.

[0077] The initiator 32 can also be a thermal initiator, which includes a thermistor that is sensitive to the external temperature. When a fire occurs, the thermistor can sense the increase in external temperature and generate heat, causing the air pressure in the sealed chamber 1113 to increase, thereby automatically triggering the striker 31 to move and open the sealed container 21.

[0078] Of course, the initiator 32 may also include both an electric initiator and a thermal initiator, so that the fire extinguishing device can be started manually or automatically, effectively preventing the risk caused by the failure of the fire extinguishing device to start.

[0079] In an illustrative embodiment, Figure 1 As shown, the housing 1 includes: a shell 11 and a sealing structure 12. The shell 11 is provided with a first installation cavity 111. The striker 31 and the piston 16 are located in the first installation cavity 111. One end of the first installation cavity 111 is open. The sealing structure 12 is connected to the shell 11 and seals the open end of the first installation cavity 111. The initiator 32 is penetrated through the sealing structure 12. The space between the sealing structure 12 and the piston 16 forms a sealing cavity 1113.

[0080] Splitting the shell 1 into multiple components such as the outer shell 11 and the sealing structure 12 is not only conducive to reducing the processing difficulty of each component, but also convenient for reasonably selecting the material of each component according to needs, and also convenient for assembling the components inside the shell 1, thereby optimizing the structure of the starting device 100 and reducing the assembly difficulty of the starting device 100.

[0081] In addition, the sealing structure 12 and the piston 16 are used to define a sealing cavity 1113 in the housing 11 . The sealing structure 12 and the piston 16 can seal both ends of the sealing cavity 1113 , thereby facilitating improving the sealing reliability of the sealing cavity 1113 .

[0082] The housing 11 may be a metal housing 11, and the piston 16 may be a silicone piston 16 or a rubber piston 16. Furthermore, the striker 31 may be a metal piece with a high hardness, so as to quickly pierce the sealed container 21.

[0083] In an illustrative embodiment, Figure 1 As shown, the sealing structure 12 includes: a first cover 121 and a sealing plug 122. The first cover 121 is connected to the housing 11 and covers the open end of the first installation cavity 111. The sealing plug 122 is at least partially located in the first installation cavity 111 and abuts against the first cover 121. The space between the sealing plug 122 and the piston 16 forms a sealing cavity 1113.

[0084] The sealing structure 12 includes a first cover 121 and a sealing plug 122. The sealing plug 122 and the piston 16 define a sealing cavity 1113 in the housing 11. The sealing plug 122 and the piston 16 can seal both ends of the sealing cavity 1113, thereby improving the sealing reliability of the sealing cavity 1113. The first cover 121 can fix the sealing plug 122, prevent the sealing plug 122 from moving or falling off, and improve the reliability of the sealing plug 122. The sealing plug 122 can be a silicone plug or a rubber plug.

[0085] In an exemplary embodiment, the first installation cavity 111 includes: an installation groove 1111 and a sliding channel 1112. The installation groove 1111 is used to install the first cover 121 and the sealing plug 122. The sliding channel 1112 is connected to the installation groove 1111. The cross-sectional area of ​​the sliding channel 1112 is smaller than the cross-sectional area of ​​the installation groove 1111, so that a support surface 1114 (such as Figure 3 The sealing plug 122 abuts against the supporting surface 1114. The piston 16 is located in the sliding channel 1112 and slidably cooperates with the sliding channel 1112.

[0086] Since the cross-sectional areas of the mounting groove 1111 and the sliding channel 1112 are different, the first mounting cavity 111 forms a stepped hole structure. In addition, the entrance end of the stepped hole structure is relatively thick, which facilitates the piston 16 and the striker 31 to be quickly and conveniently inserted into the sliding channel 1112, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0087] On the other hand, the supporting surface 1114 of the stepped hole structure also serves to limit the sealing plug 122 , thereby preventing the sealing plug 122 from moving into the sliding channel 1112 , thereby further improving the stability of the sealing plug 122 .

[0088] In addition, the support surface 1114 of the stepped hole also plays a role in assembling and positioning the sealing plug 122. When the sealing plug 122 abuts against the support surface 1114, it indicates that the sealing plug 122 is installed in place, which can prevent the sealing plug 122 from being over-extruded and affecting the service life of the sealing plug 122.

[0089] In an illustrative embodiment, Figure 1 As shown, the first cover 121 is provided with a limiting groove 1211. A portion of the sealing plug 122 is limited in the limiting groove 1211. The initiator 32 is provided through the sealing plug 122 and the first cover 121.

[0090] Limiting a portion of the sealing plug 122 in the limiting groove 1211 of the first cover 121 is conducive to further improving the stability of the sealing plug 122. In addition, this solution facilitates first assembling the first cover 121, the sealing plug 122 and the initiator 32 into a module, and then assembling the module with the housing 11, which is conducive to reducing the difficulty of assembly and improving the assembly efficiency.

[0091] Furthermore, the first cover 121 may be a metal cover. The first cover 121 and the housing 11 may be connected by threads, which is reliable and easy to assemble.

[0092] In an illustrative embodiment, Figure 1 As shown, the housing 1 is provided with a mounting hole 131 and at least one air passage 132. The sealed container 21 includes a head 211 and a body 212. Figure 2 The head 211 is installed in the mounting hole 131, and the head 211 is arranged corresponding to the striker 31, and is used to eject the gas formed by the driving medium 22. The gas passage 132 is connected to the mounting hole 131, and one end of the gas passage 132 passes through the housing 1, and is used to transport the gas formed by the driving medium 22 to the fire extinguishing agent storage container 210.

[0093] The housing 1 is provided with a mounting hole 131 and a gas passage 132. The mounting hole 131 is used to mount the head 211 of the sealed container 21, and the body 212 of the sealed container 21 can be inserted into the fire extinguishing agent storage container 210. The gas passage 132 is used to transport gas to the fire extinguishing agent storage container 210, so that the fire extinguishing agent storage container 210 is quickly pressurized and then the fire extinguishing agent 220 is ejected. The gas passage 132 is connected to the mounting hole 131 to ensure that the gas ejected from the head 211 of the sealed container 21 can enter the gas passage 132; one end of the gas passage 132 passes through the housing 1 to ensure that after the housing 1 and the fire extinguishing agent storage container 210 are assembled, the gas passage 132 can be connected to the fire extinguishing agent storage container 210.

[0094] Of course, when the starting device is used for other equipment, the gas passage is used to transport the gas formed by the driving medium to the container body of the other equipment.

[0095] In an illustrative embodiment, Figure 1 As shown, the housing 1 includes a shell 11 and a support seat 13. A second installation cavity 112 is provided in the shell 11. The support seat 13 is installed in the second installation cavity 112. A mounting hole 131 and an air passage 132 are provided on the support seat 13.

[0096] Splitting the shell 1 into multiple components such as the outer shell 11 and the support seat 13 is beneficial to reducing the processing difficulty of each component, and is also convenient for reasonably selecting the material of each component according to needs, and is also convenient for assembling the components inside the shell 1, thereby optimizing the structure of the starting device 100 and reducing the assembly difficulty of the starting device 100.

[0097] Furthermore, the support base 13 is threadedly connected to the housing 11, which is reliable and easy to assemble. The head 211 of the sealed container 21 is threadedly connected to the support base 13, which is reliable and easy to assemble.

[0098] Furthermore, there are multiple air passages 132, and the multiple air passages 132 are arranged at intervals along the circumference of the support seat 13, such as Figure 4 As shown, this facilitates the gas to enter the fire extinguishing agent storage container 210 quickly and evenly.

[0099] In an illustrative embodiment, Figure 1 As shown, the starting device 100 further includes a first sealing film 141 . The first sealing film 141 is disposed in the second installation cavity 112 and between the striker 31 and the sealing container 21 , and the first sealing film 141 abuts against an end of the support seat 13 close to the striker 31 .

[0100] When a fire occurs, the striker 31 punctures the first sealing film 141, and then punctures the sealed container 21. The provision of the first sealing film 141 is conducive to preventing the striker 31 from being triggered by mistake and causing the sealed container 21 to be punctured, thereby improving the safety of the starting device 100.

[0101] The first sealing diaphragm 141 may be an aluminum diaphragm or other materials.

[0102] In an illustrative embodiment, Figure 1 As shown, the housing 1 is provided with at least one ejection channel 114, and the ejection channel 114 is connected to the ejection port 1513. The starting device 100 further includes a second sealing membrane 142. The second sealing membrane 142 is arranged corresponding to the ejection port 1513, and is used to disconnect the ejection channel 114 from the ejection port 1513.

[0103] The ejection channel 114 is configured to be able to communicate with the fire extinguishing agent storage container 210. The second sealing diaphragm 142 ensures that the ejection channel 114 and the nozzle 1513 are disconnected when the fire extinguishing device 200 is not in use, thereby preventing the fire extinguishing agent 220 from being ejected and causing property loss or personal injury. In the event of a fire, when the triggering device 3 opens the sealed container 21, the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 flows to the ejection channel 114 under the action of air pressure, and then breaks through the second sealing diaphragm 142, and is ejected from the nozzle 1513 to extinguish the fire. Of course, when the starting device 100 is used for other equipment, the ejection channel 114 is configured to be able to communicate with the container body of other equipment.

[0104] Compared with the solution of using a sealing valve to disconnect the nozzle 1513 and the ejection channel 114, and further using an elastic member to improve the stability of the sealing valve, the structure of this solution is simpler.

[0105] The second sealing diaphragm 142 may be an aluminum diaphragm or other diaphragms.

[0106] Furthermore, the number of ejection channels 114 can be equal to and correspond to the number of nozzles 1513. At this time, the number of second sealing membranes 142 can be equal to and correspond to the number of ejection channels 114 to ensure that each ejection channel 114 and nozzle 1513 can be in a disconnected state when there is no fire.

[0107] The number of ejection channels 114 may not be equal to the number of nozzles 1513. For example, the ejection channel 114 may be a three-way structure, a four-way structure, etc. Then, one ejection channel 114 may be connected to three or four nozzles 1513, which is helpful to reduce the number of second sealing diaphragms 142, thereby simplifying the product structure and reducing product costs.

[0108] In an illustrative embodiment, Figure 1 As shown, the starting device 100 further includes: a siphon tube 4 fixedly connected to the shell 1 and communicated with the ejection channel 114 .

[0109] After the starting device 100 and the fire extinguishing agent storage container 210 are assembled, the siphon tube 4 is inserted into the fire extinguishing agent storage container 210. The siphon tube 4 can use the siphon principle to suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the ejection channel 114, so that the fire extinguishing agent 220 continuously enters the ejection channel 114, thereby improving the fire extinguishing efficiency. Further, the siphon tube 4 is a plastic tube, and the siphon tube 4 is threadedly connected to the housing 1.

[0110] Of course, for small fire extinguishing equipment, the amount of fire extinguishing agent 220 is relatively small, and the siphon tube 4 can also be eliminated. Alternatively, in the case where the fire extinguishing agent storage container 210 is on the top and the starting device 100 is on the bottom, the fire extinguishing agent 220 can automatically flow to the ejection channel 114 under the action of gravity, and the siphon tube 4 can also be eliminated in this case.

[0111] In an illustrative embodiment, Figure 1 As shown, the housing 1 includes a shell 11 and an injection structure 15. A third installation cavity 113 for installing the injection structure 15 is provided in the shell 11. One end of the third installation cavity 113 is open, and the other end of the third installation cavity 113 is connected to the injection channel 114. The nozzle 1513 is provided on the injection structure 15. The second sealing diaphragm 142 is provided between the injection channel 114 and the injection structure 15.

[0112] Splitting the shell 1 into multiple components such as the outer shell 11 and the injection structure 15 is not only conducive to reducing the processing difficulty of each component, but also convenient for reasonably selecting the material of each component according to needs, and also convenient for assembling the components inside the shell 1, thereby optimizing the structure of the starting device 100 and reducing the assembly difficulty of the starting device 100.

[0113] The second sealing membrane 142 may be installed first, and then the injection structure 15 may be installed.

[0114] In an illustrative embodiment, Figure 1 As shown, the injection structure 15 includes: a second cover 152 and a nozzle 151. The second cover 152 is arranged at the open end of the third installation cavity 113 and abuts against the second sealing membrane 142, and the second cover 152 is provided with a through hole. The nozzle 151 is installed at the through hole, and the nozzle 151 is connected to the third installation cavity 113, and the nozzle 1513 is arranged on the nozzle 151.

[0115] The spray structure 15 includes a second cover 152 and a nozzle 151, and the second cover 152 is fixedly connected to the housing 11. The nozzle 151 is mounted on the second cover 152, so that the nozzle 151 of a desired shape can be selected according to the needs to optimize the product structure.

[0116] Furthermore, the second cover 152 is threadedly connected to the housing 11, and the nozzle 151 is threadedly connected to the second cover 152. The threaded connection method is reliable and easy to assemble.

[0117] Further, if Figure 1As shown, an input channel 1511 and an output channel 1512 may be provided in the nozzle 151, and the input channel 1511 is communicated with the third installation cavity 113. The output channel 1512 is communicated with the input channel 1511, and the outlet of the output channel 1512 is formed as a nozzle 1513. The number of the input channels 1511 may be one or more, and the number of the output channels 1512 may be one or more. The nozzle 151 may be generally in a columnar structure, the input channel 1511 may be provided along the radial direction of the nozzle 151, and the output channel 1512 may be provided along the axial direction of the nozzle 151.

[0118] In an exemplary embodiment, the driving medium 22 is a gaseous medium.

[0119] The driving medium 22 may be a gaseous medium stored in the sealed container 21 and ejected quickly when the sealed container 21 is opened. The driving medium 22 may be nitrogen, argon, carbon dioxide, air or the like, and the pressure level may be higher than 1.2 MPa.

[0120] In another exemplary embodiment, the driving medium 22 is a liquid medium.

[0121] The driving medium 22 may also be a liquid medium that can be packaged in the sealed container 21 in liquid form and vaporizes into gas to be ejected after the sealed container 21 is opened, such as liquid carbon dioxide, liquid propane, etc. In other words, the driving medium 22 is a liquid-to-gas medium.

[0122] Alternatively, the driving medium 22 may also be a solid medium, which is packaged in the sealed container 21 in a solid form and sublimates into gas and is ejected after the sealed container 21 is opened, such as solid carbon dioxide (dry ice).

[0123] In other words, the driving medium 22 is a solid-to-gas medium, which is directly converted into gas by depressurizing the sealed container 21, rather than generating gas by combustion or explosion, so the gas generating device 2 is still a non-explosive product.

[0124] Alternatively, the driving medium 22 includes any combination of a gaseous medium, a liquid medium, and a solid medium. In other words, the driving medium 22 may also include a gaseous medium and a liquid medium. Alternatively, the driving medium 22 may also include a gaseous medium and a solid medium. Alternatively, the driving medium 22 may also include a liquid medium and a solid medium. Alternatively, the driving medium 22 may also include a gaseous medium, a liquid medium, and a solid medium. As long as the two media in different states or the three media in different states sealed in the sealed container 21 do not react with each other and can all be ejected in a gaseous form after the sealed container 21 is opened.

[0125] In an exemplary embodiment, the Rockwell hardness of the striker 31 is greater than or equal to HR60.

[0126] Setting the hardness of the striker 31 within the above range can ensure that the striker 31 can pierce the sealed container 21 quickly and effectively.

[0127] In an exemplary embodiment, the diameter of the needle tip of the firing pin 31 is between 2 mm and 3 mm.

[0128] Limiting the diameter of the needle tip of the striker 31 to between 2 mm and 3 mm can ensure that the gas can be ejected quickly after the sealed container 21 is punctured.

[0129] Embodiment 2

[0130] like Figure 4 As shown, another embodiment of the present invention provides a starting device 100'. The starting device 100' comprises: a housing 1', a gas generating device 2' and a triggering device 3'.

[0131] Specifically, the housing 1' is provided with at least one nozzle 115'. The gas generating device 2' comprises an integrated sealed container 21' and a driving medium 22' sealed in the sealed container 21'. The sealed container 21' is connected to the housing 1'. The triggering device 3' is located outside the gas generating device 2'.

[0132] The difference from the above-mentioned embodiment 1 is that:

[0133] The triggering device 3' includes a striker 31' and an initiator 32'. The striker 31' is arranged corresponding to the sealed container 21' and is used to puncture the sealed container 21' so that the driving medium 22' is ejected from the sealed container 21' and forms gas. The initiator 32' cooperates with the striker 31' and is used to drive the striker 31' to move in a direction close to the sealed container 21' so that the striker 31' punctures the sealed container 21'.

[0134] The initiator 32' is used to drive the striker 31' to move. The striker 31' can use the tip portion to quickly pierce the sealed container 21' without generating sparks, is safe to use, and has high opening efficiency.

[0135] In an illustrative example, further, Figure 4 As shown, the striker 31' is located in the housing 1' and forms a sealed cavity 1111' with the housing 1'. One end of the initiator 32' is located in the sealed cavity 1111' and is used to increase the air pressure in the sealed cavity 1111' to drive the striker 31' to move toward the sealed container 21'. The other end of the initiator 32' passes through the housing 1' and extends to the outside of the housing 1'.

[0136] In this embodiment, the initiator 32' is specifically used to increase the air pressure in the sealed chamber 1111', and then use the increased air pressure to drive the striker 31' to move, which is an ingenious concept.

[0137] In an illustrative example, further, Figure 4 As shown, the striker 31' includes: a sliding portion 311' and a piercing portion 312'. The sliding portion 311' and the housing 1' enclose a sealed cavity 1111' and slide with the housing 1'. The piercing portion 312' is connected to the sliding portion 311' and is disposed toward the sealed container 21' for piercing the sealed container 21'.

[0138] The striker 31' comprises a sliding portion 311' and a puncture portion 312'. The sliding portion 311' and the housing 1' slide together to ensure that the striker 31' can smoothly move relative to the housing 1'. The puncture portion 312' is arranged corresponding to the sealed container 21' to realize the puncture function of the striker 31'.

[0139] The outer wall of the sliding portion 311' may be cylindrical, so that there are no edges or corners between the sliding portion 311' and the housing 1', which is conducive to reducing the probability of jamming between the striker 31' and the housing 1', thereby improving the reliability of the starting device 100'. The piercing portion 312' may include a conical structure, which has both high strength and a sharper portion.

[0140] In an illustrative example, further, Figure 4 As shown, the sliding part 311' includes an end plate 3111' and a side plate 3112'. The side plate 3112' is connected to the edge of the end plate 3111' and forms a groove with one end open with the end plate 3111'. The housing 1' seals the open end of the groove and forms a sealed cavity 1111' with the sliding part 311'. The puncture part 312' is connected to the plate surface of the end plate 3111' away from the side plate 3112'.

[0141] In this solution, the sliding portion 311' adopts a hollow structure, and a sealed cavity 1111' is enclosed by the sliding portion 311' and the shell 1'. On the one hand, it is beneficial to reduce the volume of the sealed cavity 1111', thereby facilitating an increase in the air pressure in the sealed cavity 1111'; on the other hand, it is also beneficial to reduce the mass of the striker 31', thereby facilitating a reduction in the air pressure value that drives the striker 31' to move, thereby increasing the triggering speed of the triggering device 3'.

[0142] Furthermore, the end plate 3111 ′, the side panel 3112 ′ and the piercing portion 312 ′ are an integrated structure, that is, the striker 31 ′ is formed in one piece, so that the striker 31 ′ has a higher strength and is conducive to improving assembly efficiency.

[0143] In an illustrative example, further, Figure 4As shown, the housing 1' includes a shell 11' and a sealing plug 12'. A first installation cavity 111' is provided in the shell 11'. The sealing plug 12' and at least a portion of the striker 31' are located in the first installation cavity 111'. The sliding portion 311' is slidably matched with the shell 11'. The sealing plug 12' and the sliding portion 311' enclose a sealing cavity 1111'.

[0144] Splitting the housing 1' into multiple parts such as the outer shell 11' and the sealing plug 12' is not only conducive to reducing the difficulty of processing each part, but also convenient for reasonably selecting the material of each part according to needs, and also convenient for assembling the parts inside the housing 1', thereby optimizing the structure of the starting device 100' and reducing the difficulty of assembling the starting device 100'. Using the sealing plug 12' to block the groove of the sliding part 311' is conducive to improving the sealing reliability of the sealing cavity 1111'. Among them, the outer shell 11' can be a metal shell. The sealing plug 12' can be a rubber plug or a silicone plug.

[0145] In an illustrative example, further, the striker 31' can be made of metal with high hardness to facilitate rapid puncturing of the sealed container 21'. At least one sealing ring is sleeved between the sliding portion 311' and the housing 11' to further improve the sealing reliability of the sealed cavity 1111'. The side panel 3112' of the sliding portion 311' is provided with at least one sealing groove 3113' for installing the sealing ring, such as Figure 4 As shown, the housing 11' is provided with a through hole, and the initiator 32' passes through the sealing plug 12' and the through hole extends to the outside of the housing 1'.

[0146] In an illustrative example, further, Figure 4 As shown, the housing 1' is provided with a mounting hole 131' and at least one air passage 132'. The sealed container 21' includes a head 211' and a body 212'. Figure 5 As shown. The head 211' is installed in the mounting hole 131', and the head 211' is arranged corresponding to the striker 31', and is used to eject the gas formed by the driving medium 22'. The gas passage 132' is connected to the mounting hole 131', and one end of the gas passage 132' passes through the shell 1', and is used to transport the gas formed by the driving medium 22' to the fire extinguishing agent storage container 210'.

[0147] The shell 1' is provided with a mounting hole 131' and a gas passage 132'. The mounting hole 131' is used to mount the head 211' of the sealed container 21', and the body 212' of the sealed container 21' can be inserted into the fire extinguishing agent storage container 210'. The gas passage 132' is used to transport gas to the fire extinguishing agent storage container 210', so that the fire extinguishing agent storage container 210' is quickly pressurized, and then the fire extinguishing agent 220' is sprayed out. The gas passage 132' is connected with the mounting hole 131' to ensure that the gas sprayed from the head 211' of the sealed container 21' can enter the gas passage 132'; one end of the gas passage 132' passes through the shell 1' to ensure that after the shell 1' and the fire extinguishing agent storage container 210' are assembled, the gas passage 132' can be connected with the fire extinguishing agent storage container 210'.

[0148] In an illustrative example, further, Figure 4 As shown, the housing 1' comprises an outer shell 11' and a support base 13'. A second mounting cavity 112' is provided in the outer shell 11'. The support base 13' is installed in the second mounting cavity 112'. A mounting hole 131' and an air passage 132' are provided on the support base 13'.

[0149] Splitting the housing 1' into multiple parts such as the outer shell 11' and the support seat 13' is not only conducive to reducing the difficulty of processing each part, but also convenient for reasonably selecting the material of each part according to needs, and also convenient for assembling the parts inside the housing 1', thereby optimizing the structure of the starting device 100' and reducing the difficulty of assembling the starting device 100'.

[0150] In an illustrative example, the support seat 13' is further provided with an avoidance hole 133', and the avoidance hole 133' is connected to the mounting hole 131'. The puncture portion 312' is inserted into the avoidance hole 133', such as Figure 4 The cross-sectional area of ​​the avoidance hole 133' is larger than the cross-sectional area of ​​the mounting hole 131'. The air passage 132' penetrates both ends of the support seat 13' along the axial direction of the avoidance hole 133', and the air passage 132' penetrates the hole wall of the avoidance hole 133' along the radial direction of the avoidance hole 133'.

[0151] In this embodiment, the setting of the avoidance hole 133' reduces the distance between the striker 31' and the sealed container 21', making it easier for the striker 31' to quickly pierce the sealed container 21'. At the same time, the avoidance hole 133' is relatively thicker, and the mounting hole 131' is relatively thinner, so that the air passage 132' can penetrate the hole wall of the avoidance hole 133' along the radial direction of the avoidance hole 133', so that the hole wall of the avoidance hole 133' is not a complete annular structure in the circumferential direction, while the hole wall of the mounting hole 131' can be a complete annular structure in the circumferential direction. In this way, the mounting hole 131' and the head 211' of the sealed container 21' can have a larger contact area to improve the fixing reliability of the sealed container 21'; and the gas ejected from the head 211' in the mounting hole 131' can more easily enter the air passage 132', thereby improving the triggering speed of the triggering device 3'.

[0152] Furthermore, the cross section of the avoidance hole 133' is circular. The cross section of the mounting hole 131' is circular. The avoidance hole 133' is coaxially arranged with the mounting hole 131', and the radius of the avoidance hole 133' is greater than the radius of the mounting hole 131'.

[0153] Furthermore, the support base 13' is threadedly connected to the housing 11', which is reliable and easy to assemble. The head 211' of the sealed container 21' is threadedly connected to the support base 13', which is reliable and easy to assemble.

[0154] Furthermore, there are multiple gas passages 132', which are spaced apart along the circumference of the support seat 13', so that the gas can enter the fire extinguishing agent storage container 210' quickly and evenly.

[0155] In an illustrative example, further, Figure 4 As shown, the cross-sectional area of ​​the second mounting cavity 112' is greater than the cross-sectional area of ​​the first mounting cavity 111', so that the first mounting cavity 111' and the second mounting cavity 112' form a stepped hole structure. The end surface of the support seat 13' close to the first mounting cavity 111' abuts against the end surface of the second mounting cavity 112'. The end surface of the support seat 13' close to the first mounting cavity 111' protrudes from the inner side surface of the first mounting cavity 111', forming a stop surface 134' for stopping the striker 31', as shown in FIG. Figure 4 shown.

[0156] During assembly, the sealing plug 12' can be first inserted into the first installation cavity 111' through the second installation cavity 112', and then the striker 31' can be inserted into the first installation cavity 111' through the second installation cavity 112', and then the support seat 13' can be inserted into the second installation cavity 112' until the support seat 13' abuts against the step of the stepped hole, and then the head 211' of the sealing container 21' can be inserted into the installation hole 131' of the support seat 13'. In this way, the assembly process of the starting device 100' is simple and convenient.

[0157] In addition, during use, when the striker 31' moves to abut against the support seat 13', it will be stopped by the support seat 13' and cannot continue to move, thereby limiting the sliding stroke of the striker 31' and preventing the striker 31' from moving too much and causing the sealed container 21' to deform excessively and fall off.

[0158] Furthermore, the piercing portion 312' of the striker 31' is provided with a transition channel 3121' connected to the air passage 132', such as Figure 4 As shown. In this way, the gas in the sealed container 21' can also enter the gas passage 132' through the transition passage 3121', thereby further improving the initiation speed of the initiator 3'. In addition, this can also further reduce the mass of the striker 31' and further reduce the requirements for the initiator 32'.

[0159] In an illustrative example, further, Figure 4 As shown, the housing 1' is provided with at least one ejection channel 116', and the ejection channel 116' is connected with the nozzle 115'. The starting device 100' further includes a sealing valve 4', which is used to disconnect the ejection channel 116' from the nozzle 115', and the sealing valve 4' is configured to connect the ejection channel 116' with the nozzle 115' under the impact of a fluid (such as a fire extinguishing agent 220').

[0160] The ejection channel 116' is configured to be able to communicate with the fire extinguishing agent storage container 210'. The sealing valve 4' ensures that the ejection channel 116' and the nozzle 115' are in a disconnected state when the fire extinguishing device is not in use, thereby preventing the fire extinguishing agent 220' from being ejected and causing property damage or personal injury. In the event of a fire, when the triggering device 3' opens the sealed container 21', the fire extinguishing agent in the fire extinguishing agent storage container 210' flows to the ejection channel 116' under the action of air pressure, and then breaks open the sealing valve 4', and is ejected from the nozzle 115' to extinguish the fire. Of course, when the starting device 100' is used for other equipment, the ejection channel 116' is configured to be able to communicate with the container body of other equipment.

[0161] The sealing valve 4' may be a metal sealing plug which is interference fit with the housing 1'.

[0162] Furthermore, at least one sealing ring is sleeved between the sealing valve 4' and the housing 1' to further improve the sealing reliability of the sealing valve 4'. A sealing groove 3113' for installing the sealing ring is provided on the outer side wall of the sealing valve 4'.

[0163] Furthermore, the number of ejection channels 116' can be equal to and correspond to the number of nozzles 115', and the number of sealing valves 4' can be equal to and correspond to the number of ejection channels 116' to ensure that each ejection channel 116' and nozzle 115' can be disconnected when there is no fire.

[0164] The number of ejection channels 116' may not be equal to the number of nozzles 115'. For example, the ejection channel 116' may be a three-way structure, a four-way structure, etc. Then, one ejection channel 116' may be connected to three or four nozzles 115', which is helpful to reduce the number of sealing valves 4', thereby simplifying the product structure and reducing product costs.

[0165] In an illustrative example, further, Figure 4 As shown, the starting device 100' further includes: a siphon tube 5', which is fixedly connected to the housing 1' and communicated with the ejection channel 116'.

[0166] After the starter 100' and the fire extinguishing agent storage container 210' are assembled, the siphon 5' is inserted into the fire extinguishing agent storage container 210'. The siphon 5' can use the siphon principle to suck the fire extinguishing agent 220' in the fire extinguishing agent storage container 210' into the ejection channel 116', so that the fire extinguishing agent 220' continuously enters the ejection channel 116', thereby improving the fire extinguishing efficiency. Further, the siphon 5' is a plastic tube, and the siphon 5' is threadedly connected to the housing 1'.

[0167] Of course, for small fire extinguishing equipment, the amount of fire extinguishing agent 220' is relatively small, and the siphon tube 5' can also be eliminated. Alternatively, for the case where the fire extinguishing agent storage container 210' is on the top and the starting device 100' is on the bottom, the fire extinguishing agent 220' can automatically flow to the ejection channel 116' under the action of gravity, and the siphon tube 5' can also be eliminated in this case.

[0168] In an illustrative example, further, Figure 4 As shown, the housing 1' is further provided with a third installation cavity 113' and an avoidance cavity 117' connected to the third installation cavity 113'. The sealing valve 4' is installed in the third installation cavity 113' to disconnect the connection between the ejection channel 116' and the nozzle 115', and is configured to be able to move to the avoidance cavity 117' under the impact of a fluid (such as a fire extinguishing agent 220') to connect the ejection channel 116' and the nozzle 115'.

[0169] In this way, after the sealing valve 4' is impacted by the fire extinguishing agent 220', it is still located in the housing 1', which can prevent the sealing valve 4' from bursting out and causing property loss or covering people.

[0170] In an illustrative example, further, Figure 4As shown, the starting device 100' further includes: an elastic member 6', which is disposed in the housing 1' and abuts against the sealing valve 4' to limit the sealing valve 4' from moving toward the avoidance chamber 117'.

[0171] The elastic member 6' can exert a force on the sealing valve 4', thereby improving the position stability of the sealing valve 4' and preventing the fire extinguishing agent 220' from being sprayed out by mistake when there is no fire, thereby causing property loss or personal injury.

[0172] The elastic member 6' may be a compression spring, a spring, a silicone ball or the like.

[0173] In an illustrative example, further, Figure 4 As shown, the housing 1' comprises a sealing cover 14' and a shell 11'. The shell 11' is provided with a fourth installation cavity 114' with two ends opened. One end of the fourth installation cavity 114' is connected to the third installation cavity 113', and the sealing cover 14' is used to cover the end of the fourth installation cavity 114' away from the third installation cavity 113'.

[0174] Splitting the housing 1' into multiple parts such as the outer shell 11' and the sealing cover 14' is not only conducive to reducing the difficulty of processing each part, but also convenient for reasonably selecting the material of each part according to needs, and also convenient for assembling the parts inside the housing 1', thereby optimizing the structure of the starting device 100' and reducing the difficulty of assembling the starting device 100'.

[0175] Specifically, during the assembly process, the sealing valve 4' can be first installed into the third installation cavity 113' through the fourth installation cavity 114', and then the elastic member 6' can be installed into the housing 11' so that the elastic member 6' and the sealing valve 4' are abutted, and then the sealing cover 14' can be covered.

[0176] Further, if Figure 4 As shown, the sealing cover 14 ′ is provided with a limiting groove 141 ′, and a part of the elastic member 6 ′ is limited in the limiting groove 141 ′.

[0177] The limiting groove 141 ′ can limit the elastic member 6 ′, thereby preventing the elastic member 6 ′ from tilting, shifting, etc., thereby improving the reliability of the elastic member 6 ′.

[0178] In an illustrative example, further, Figure 4 As shown, the end of the sealing valve 4' facing the sealing cover 14' is also provided with a limiting groove 42'. One end of the elastic member 6' can be inserted into the limiting groove 42', which is beneficial to further prevent the elastic member 6' from tilting, shifting, etc., and ensure good cooperation between the elastic member 6' and the sealing valve 4'.

[0179] Further, if Figure 4As shown, a limiting boss 41' is provided at one end of the sealing valve 4' facing the sealing cover 14'. The cross-sectional area of ​​the limiting boss 41' is larger than the cross-sectional area of ​​the third installation cavity 113', so as to prevent the sealing valve 4' from being stuck in the third installation cavity 113' and affecting the normal spraying of the fire extinguishing agent 220'.

[0180] like Figure 6 As shown, an embodiment of the present invention further provides a fire extinguishing device 200, comprising: a fire extinguishing agent storage container 210 and a starting device 100 as described in the first embodiment above.

[0181] The fire extinguishing agent storage container 210 contains the fire extinguishing agent 220.

[0184] The shape of the fire extinguishing agent storage container 210 is not limited. For example, the cross section of the fire extinguishing agent storage container 210 can be circular, elliptical, triangular, polygonal, and the like.

[0190] The fire extinguishing device 200' provided in this embodiment includes the starting device 100' provided in the above-mentioned embodiment 2, and thus has all the beneficial effects of the above-mentioned embodiment 2, which will not be described in detail here.

[0193] In another exemplary embodiment, the fire extinguishing equipment 200 ′ is a dry powder fire extinguishing equipment.

[0194] In yet another exemplary embodiment, the fire extinguishing device 200 ′ is a liquid fire extinguishing device.

[0195] Two specific examples are described below with reference to the accompanying drawings.

[0196] Specific Example 1

[0197] This specific example provides a gas fire extinguishing device, including a starting device 100 and a fire extinguishing agent storage container 210, wherein the fire extinguishing agent storage container 210 contains a gas fire extinguishing agent.

[0198] The starting device 100 includes: a housing 1, a gas generating device 2, a triggering device 3, a piston 16, a first sealing diaphragm 141, a second sealing diaphragm 142 and a siphon 4. The housing 1 includes: an outer shell 11, a sealing structure 12, a support seat 13 and an injection structure 15. The gas generating device 2 includes a sealed container 21 and a driving medium 22 encapsulated in the sealed container 21. The triggering device 3 includes a striker 31 and an electric initiator. The sealing structure 12 includes a first cover 121 and a sealing plug 122. The injection structure 15 includes a second cover 152 and a nozzle 151.

[0199] The housing 11 is threadedly connected to the fire extinguishing agent storage container 210. A first installation cavity 111, a second installation cavity 112 and a third installation cavity 113 are provided in the housing 11. The first installation cavity 111 includes a mounting groove 1111 and a sliding channel 1112. A support surface 1114 is formed between the mounting groove 1111 and the sliding channel 1112. The first cover 121 is threadedly connected to the groove wall of the mounting groove 1111. A part of the sealing plug 122 is limited in the limiting groove 1211 of the first cover 121. The sealing plug 122 abuts against the first cover 121 and the support surface 1114. The piston 16 and the striker 31 are installed in the sliding channel 1112. The space between the piston 16 and the sealing plug 122 forms a sealing cavity 1113. The striker 31 is fixedly connected to the piston 16. The resistor 321 of the electric initiator is located in the sealing cavity 1113, and the connecting wire 322 passes through the sealing plug 122 and the first cover 121 and extends to the outside of the housing 11.

[0200] The support seat 13 is installed in the second installation cavity 112 by threaded connection. The head 211 of the sealed container 21 is threadedly connected to the support seat 13, and the body 212 of the sealed container 21 is inserted into the fire extinguishing agent storage container 210. The support seat 13 is provided with an air passage 132, and the air passage 132 is connected to the fire extinguishing agent storage container 210. The first sealing diaphragm 141 is provided between the head 211 of the sealed container 21 and the striker 31, and is clamped between the support seat 13 and the top wall of the second installation cavity 112.

[0202] When a fire occurs, the electric initiator is powered on, the resistor 321 generates heat, and the air pressure in the sealed chamber 1113 increases. The increased air pressure in the sealed chamber 1113 drives the piston 16 to move toward the gas production device 2, and the piston 16 drives the striker 31 to move synchronously, so that the striker 31 pierces the first sealing membrane 141 and the sealed container 21, and the driving medium 22 in the sealed container 21 is ejected from the sealed container 21 and forms gas. The ejected gas enters the fire extinguishing agent storage container 210 through the gas passage 132, so that the fire extinguishing agent storage container 210 is rapidly pressurized, and then drives the fire extinguishing agent 220 to enter the fire extinguishing agent ejection channel 114 through the siphon 4, and breaks through the second sealing membrane 142, and is ejected through the nozzle 151 to extinguish the fire.

A sealed cavity 1111' is formed between the sealing plug 12' and the striker 31'. The sealed container 21' includes a head 211' and a body 212'. The head 211' is installed in the mounting hole 131', and the body 212' is inserted into the fire extinguishing agent storage container 210'.
