Abstract
Description
Technical Field
[0001] This article relates to the technical field of fire-fighting equipment, and in particular to a fire-fighting equipment and vehicle. Background Art
[0002] In related technologies, vehicles are equipped with fire prevention and control products. For example, new energy vehicles are equipped with battery pack fire extinguishing equipment to protect the battery pack. When a battery pack experiences thermal runaway, the battery pack fire extinguishing equipment sprays fire extinguishing agent into the battery pack. Since new energy vehicles can have as many as 16 or 32 battery packs, and vehicle space is limited, the fire extinguishing dose of existing fire prevention and control products is limited to surface suppression of an initial fire in a battery pack and cannot achieve sustained fire extinguishing effects. Especially when multiple battery packs experience thermal runaway at the same time, the fire extinguishing dose is insufficient, resulting in severe consequences for mass casualties and injuries caused by the fire.

[0040] like Figure 1 As shown, an embodiment of the present application provides a fire extinguishing device 100 , comprising: a fire extinguishing apparatus 1 , a first delivery pipeline 2 , and a second delivery pipeline 3 .
[0041] Specifically, the fire extinguishing device 1 is filled with fire extinguishing agent. The first delivery pipeline 2 is connected to the fire extinguishing agent nozzle of the fire extinguishing device 1. Figure 1 The first end of the second delivery pipeline 3 is connected to the first delivery pipeline 2, and the second end of the second delivery pipeline 3 is provided with a fire interface 4 for connecting to external fire fighting equipment, as shown. Figure 2 shown.
[0042] The fire-extinguishing device 100 provided in this embodiment of the present invention, by providing a second delivery pipeline 3 and a fire interface 4, allows the device 100 to be connected to external firefighting equipment, such as a fire truck or fire hydrant. This allows firefighting water and other extinguishing media from the external firefighting equipment to enter the first delivery pipeline 2 through the second delivery pipeline 3 and be continuously delivered to the fire site, effectively extinguishing the fire there. This improves firefighting effectiveness and reduces the risk of mass casualties from fires.
[0043] Specifically, fire extinguishing equipment 100 includes a fire extinguishing device 1, a first delivery pipeline 2, and a second delivery pipeline 3. Fire extinguishing device 1 contains fire extinguishing agent. When a fire occurs, the fire extinguishing agent in fire extinguishing device 1 is sprayed through first delivery pipeline 2 to the fire site for initial extinguishing. Second delivery pipeline 3 can be connected to external firefighting equipment via firefighting interface 4, allowing firefighting water and other fire extinguishing media from the external firefighting equipment to be continuously delivered to the fire site, thereby achieving continuous and efficient post-fire extinguishing.
[0044] Compared with using external fire-fighting equipment such as fire trucks and fire hydrants to directly spray fire-extinguishing media on a large scale from the outside of the fire site (such as the battery pack 110), this solution can use the first delivery pipeline 2 to accurately deliver the fire-extinguishing medium to the fire site, so that the fire-extinguishing effect is more efficient and reliable, which is beneficial to reducing the risk of mass deaths and injuries caused by fire, and also helps to avoid unnecessary damage of the fire-extinguishing medium to the site where the fire has not occurred, thereby also helping to reduce property losses.
[0045] On the other hand, this solution can directly add a second delivery pipeline 3 and a fire interface 4 for connecting to external fire-fighting equipment on the basis of the original fire-fighting equipment 100. It has a simple structure but ingenious design, is suitable for mass production, and is conducive to the market promotion of the product.
[0046] In an exemplary embodiment, Figure 2As shown, the fire extinguishing equipment 100 further includes a one-way valve 5 . The one-way valve 5 is provided on the second delivery pipeline 3 and is used to control the second delivery pipeline 3 to flow in a one-way direction from the fire interface 4 to the first delivery pipeline 2 .
[0047] A one-way valve 5 is installed on the second delivery pipeline 3, ensuring that it can only flow in one direction. This allows the fire extinguishing medium from the external firefighting equipment to flow through the second delivery pipeline 3 into the first delivery pipeline 2 only after the fire interface 4 is connected. The fire extinguishing medium can then be sprayed onto the fire site through the first delivery pipeline 2, ensuring efficient and continuous fire extinguishing. However, the fire extinguishing agent sprayed from the fire extinguishing device 1 cannot enter the second delivery pipeline 3 through the first delivery pipeline 2, preventing leakage of the fire extinguishing agent through the second delivery pipeline 3 and affecting the fire extinguishing effect.
[0048] In an exemplary embodiment, Figure 2 As shown, the length of the pipeline between the one-way valve 5 and the first end of the second delivery pipeline 3 is shorter than the length of the pipeline between the one-way valve 5 and the fire interface 4 .
[0049] The length of the pipeline between the one-way valve 5 and the first end of the second delivery pipeline 3 refers to the length of the portion of the second delivery pipeline 3 located between the one-way valve 5 and the first end of the second delivery pipeline 3, which can be recorded as L1. The length of the pipeline between the one-way valve 5 and the fire interface 4 refers to the length of the portion of the second delivery pipeline 3 located between the one-way valve 5 and the fire interface 4, which can be recorded as L2. When L1 is less than L2, it indicates that the one-way valve 5 and the first end of the second delivery pipeline 3 are relatively close. This helps minimize the amount of fire extinguishing agent entering the second delivery pipeline 3 through the first delivery pipeline 2, thereby helping to ensure the fire extinguishing effectiveness of the fire extinguishing device 1.
[0050] It is understood that the second delivery pipeline 3 can be a flexible pipeline that can be folded, coiled, or bent. The second delivery pipeline 3 can also be a rigid pipeline. The pipeline length refers to the length of the flow path of the fire extinguishing medium within the pipeline, which is also equal to the length of the pipeline in a straight state.
[0051] In an exemplary embodiment, Figure 2 As shown, the fire extinguishing equipment 100 further includes a pressure reducing valve 6 . The pressure reducing valve 6 is provided on the second delivery pipeline 3 .
[0052] Because the pressure of external firefighting equipment is usually high, while the pressure that the first delivery pipeline 2 of a conventional fire extinguishing device 1 can withstand is relatively low, a pressure reducing valve 6 is provided on the second delivery pipeline 3 to reduce the pressure of the external firefighting equipment (e.g., the water pressure of the firefighting water) to a pressure that the second delivery pipeline 3 can withstand. This prevents damage to the first and second delivery pipelines 2 and 3 due to excessive internal pressure, thereby improving the reliability of the fire extinguishing device 100.
[0053] On the other hand, the first delivery pipeline 2 can also adopt the delivery pipeline matched with the conventional fire extinguishing device 1 without using a high-pressure pipeline, which is beneficial to reducing the cost of the fire extinguishing equipment 100.
[0054] In an exemplary embodiment, Figure 2 As shown, the length of the pipeline between the pressure reducing valve 6 and the first end of the second delivery pipeline 3 is greater than the length of the pipeline between the pressure reducing valve 6 and the fire protection interface 4 .
[0055] The length of the pipeline between the pressure reducing valve 6 and the first end of the second delivery pipeline 3 refers to the length of the portion of the second delivery pipeline 3 located between the pressure reducing valve 6 and the first end of the second delivery pipeline 3, which can be recorded as L3. The length of the pipeline between the pressure reducing valve 6 and the fire interface 4 refers to the length of the portion of the second delivery pipeline 3 located between the pressure reducing valve 6 and the fire interface 4, which can be recorded as L4. When L3 is greater than L4, it indicates that the pressure reducing valve 6 and the fire interface 4 are relatively close, which is conducive to reducing the pressure in the second delivery pipeline 3 as soon as possible, allowing the fire extinguishing medium output by the external fire fighting equipment to enter the first delivery pipeline 2 as smoothly as possible, preventing the connection between the second delivery pipeline 3 and the first delivery pipeline 2 from generating excessive impact force, which may cause the pipeline to become disconnected. This is also conducive to improving the reliability of the fire extinguishing equipment 100.
[0056] It is understood that the second delivery pipeline 3 can be a flexible pipeline that can be folded, coiled, or bent. The second delivery pipeline 3 can also be a rigid pipeline. The pipeline length refers to the length of the flow path of the fire extinguishing medium within the pipeline, which is also equal to the length of the pipeline in a straight state.
[0057] In an exemplary embodiment, the second delivery pipeline 3 is a flexible pipeline.
[0058] The second delivery pipeline 3 is in the form of a flexible pipeline, which can be folded and rolled up when not in use, thereby reducing the occupied space.
[0059] The second delivery pipeline 3 and the first delivery pipeline 2 can be made of the same material and the same diameter. Of course, the second delivery pipeline 3 and the first delivery pipeline 2 can also be made of different materials or have different diameters. In an exemplary embodiment, the fire interface 4 is configured to connect to a fire truck and / or a fire hydrant.
[0060] The fire interface 4 can be used to connect to a fire truck. When a fire occurs, the fire truck can directly connect to the fire interface 4 of the fire extinguishing device 100 after arriving, and then accurately deliver the fire extinguishing medium to the location of the fire, achieving efficient and continuous fire extinguishing. The fire interface 4 can also be used to connect to a fire hydrant, facilitating timely rescue using nearby fire hydrants.
[0061] Of course, external fire-fighting equipment is not limited to fire trucks and fire hydrants. The fire-fighting interface 4 can also be used to connect other external fire-fighting equipment that can spray fire-extinguishing media.
[0062] In an exemplary embodiment, the length of the second conveying pipeline 3 is in the range of 20 meters to 30 meters.
[0063] The length of the second delivery pipeline 3 is limited to the range of 20 meters to 30 meters, so that external fire-fighting equipment can carry out efficient and continuous fire-fighting at a suitable safe distance.
[0064] Of course, the length of the second delivery pipeline 3 is not limited to the above range and can be adjusted as needed during actual production.
[0065] In an exemplary embodiment, Figure 2 As shown, the first delivery pipeline 2 includes a first pipeline 21 and a second pipeline 22. One end of the first pipeline 21 is connected to the fire extinguishing agent outlet 11 of the fire extinguishing device 1. The fire extinguishing equipment 100 also includes a three-way pipe 9, as shown in FIG. Figure 2 The three ports of the tee pipe 9 are connected to the other end of the first pipeline 21, one end of the second pipeline 22 and the first end of the second delivery pipeline 3 respectively. The first delivery pipeline 2 also includes at least one third pipeline 23 connected to the second pipeline 22, as shown. Figure 2 As shown, a solenoid valve 7 is provided on the third pipeline 23. The fire extinguishing device 1 includes a controller (not shown in the figure). The controller is electrically connected to the solenoid valve 7 and is used to open the solenoid valve 7 when a fire occurs.
[0066] When no fire occurs, solenoid valve 7 is closed. When a fire occurs, the controller opens solenoid valve 7, ensuring that the fire extinguishing agent and the fire extinguishing medium delivered by external firefighting equipment can be smoothly discharged through third pipeline 23. The first pipeline 21, the second pipeline 22, and the second delivery pipeline 3 are connected via a tee pipe 9. This ensures that the first pipeline 21 and the second pipeline 22 are connected, thereby ensuring that the fire extinguishing agent discharged from the fire extinguishing device 1 can enter the third pipeline 23 through the second pipeline 22. It also ensures that the second pipeline 22 and the second delivery pipeline 3 are connected, thereby ensuring that the fire extinguishing medium output by the external firefighting equipment can enter the third pipeline 23 through the second pipeline 22.
[0067] The number of the third pipelines 23 is one or more. The number of the solenoid valves 7 can be equal to the number of the third pipelines 23 and correspond one to one. Of course, the number of the solenoid valves 7 can also be different from the number of the third pipelines 23.
[0068] In the case of multiple third pipelines 23, for example, if the fire extinguishing equipment is used for an on-board battery pack, there are multiple battery packs 110, with each battery pack 110 corresponding to a third pipeline 23. When a battery pack 110 catches fire, only the solenoid valve 7 on the third pipeline 23 corresponding to the burning battery pack 110 can be opened, and the fire extinguishing agent will be sprayed only toward the burning battery pack 110. Alternatively, all solenoid valves 7 can be opened, and the fire extinguishing agent will be sprayed toward all battery packs 110. Alternatively, the solenoid valves can be eliminated, and the fire extinguishing agent will be sprayed toward all battery packs 110 after a fire occurs.
[0069] Specifically, the solenoid valve 7 can be a normally closed three-way solenoid valve, or can be other types of valves. In an exemplary embodiment, the fire extinguishing device 1 includes a controller (not shown in the figure). The fire extinguishing device 100 also includes a detector 8 for detecting fire information, such as Figure 2 shown.
[0070] The controller is also electrically connected to the detector 8 and is used to automatically start the fire extinguishing device 1 according to the fire information detected by the detector 8; and / or, the controller also includes a starting element, which is used to manually start the fire extinguishing device 1.
[0071] The fire extinguishing device 1 includes a controller and an initiator, wherein the controller is used to control the initiator to start the fire extinguishing device 1. The detector 8 can be used to detect fire information and send out an alarm signal.
[0072] Among them, the controller can automatically start the initiator according to the fire information detected by the detector 8, so that the fire extinguishing device 1 automatically sprays the fire extinguishing agent to extinguish the fire. This solution realizes the automatic opening of the fire extinguishing device 1 without the need for manual opening by the user, and has a high degree of automation.
[0073] The controller may also include a starter so that the user can manually start the initiator as needed to prevent the fire extinguishing device 1 from being unable to start normally due to a failure in the automatic start mode.
[0074] Furthermore, the detector 8 may include but is not limited to one or more of the following combinations: a gas detector (such as a CO detector), a smoke sensor, a photoelectric sensor, an organic matter detector, a collision sensor, and a temperature sensor.
[0075] In an exemplary embodiment, Figures 3 to 6As shown, the fire extinguishing device includes an activation device and a fire extinguishing agent storage container containing fire extinguishing agent. The activation device is connected to the fire extinguishing agent storage container. The activation device includes a housing, a gas generating device, and an initiating device. The gas generating device includes an integrated sealed container and a driving medium sealed within the sealed container, and the sealed container is connected to the housing. The initiating device cooperates with the gas generating device to open the sealed container, causing the driving medium to be ejected from the sealed container and form a gas that drives the fire extinguishing agent in the fire extinguishing agent storage container to be ejected.
[0076] Among them, the starting device can be specifically understood by referring to the following starting device 100' and starting device 100". The fire extinguishing agent storage container can be specifically understood by referring to the following fire extinguishing agent storage container 210' and fire extinguishing agent storage container 210. The shell can be specifically understood by referring to the following shell 1' and shell 1". The gas producing device can be specifically understood by referring to the following gas producing device 2' and gas producing device 2". The initiating device can be specifically understood by referring to the following initiating device 3' and initiating device 3".
[0077] The fire extinguishing device provided in this embodiment encapsulates the driving medium within an integrated sealed container. When fire extinguishing is required, a triggering device opens the sealed container, causing the driving medium to be ejected from the container and forming a gas that drives the fire extinguishing agent. This in turn causes the fire extinguishing agent to be ejected under pressure to extinguish the fire. This eliminates the need for pressurized fire extinguishing agent storage, fundamentally resolving the pressure leakage problem of existing pressure-stored fire extinguishing devices. This eliminates the maintenance cost of regular recharging, improves the reliability of the fire extinguishing device, and eliminates the need for a pressure gauge.
[0078] The sealed container of the gas production device is an integrated structure, a sealed whole, and a complete component. It does not have sealing rings, sealants, sealing covers, sealing bolts and other structures. It can be stored independently, so there is no pressure leakage problem. The driving medium can be stably sealed in the sealed container without leakage.
[0079] Furthermore, existing non-pressure-storage fire extinguishing devices all place the triggering device inside the gas-generating device, using an electric or thermal triggering device to trigger the gas-generating device to eject gas. Since the gas-generating device is a pyrotechnic device, it cannot be used with gas fire extinguishing devices and is therefore only applicable to dry powder fire extinguishing devices. The starting device provided in this solution, however, places the triggering device outside the gas-generating device and triggers the gas-generating device to produce gas by opening a sealed container and releasing pressure. Furthermore, since the gas-generating device is a non-pyrotechnic device, it can be used not only with dry powder fire extinguishing devices, but also with gas and liquid fire extinguishing devices. This significantly expands the scope of non-pressure-storage fire extinguishing devices and resolves the long-standing pressure relief issue in the field of pressure-storage fire extinguishing devices.
[0080] Furthermore, compared to existing non-pressurized dry powder fire extinguishing devices, the initiator of this solution can prevent dry powder explosions caused by improper ignition, while also reducing the risks associated with the transportation, storage, and use of pyrotechnics. This avoids the potential safety hazards caused by the fire extinguishing device itself exploding, while also lowering the risk of managing pyrotechnics. Compared to existing pressurized gas fire extinguishing devices, the initiator of this solution can transform a pressurized gas fire extinguishing device into a non-pressurized gas fire extinguishing device, fundamentally resolving the pressure leakage issue and improving its firefighting reliability.
[0081] In an exemplary embodiment, the triggering device includes a striker and an initiator. The striker is positioned in correspondence with the sealed container and is configured to puncture the sealed container, thereby opening the sealed container. The initiator cooperates with at least one of the gas generating device and the striker to drive at least one of the gas generating device and the striker toward the other, thereby causing the striker to puncture the sealed container.
[0082] The firing pin may be specifically understood by referring to the firing pin 31 ′ and the firing pin 31 ″ described below. The initiator may be specifically understood by referring to the initiator 32 ′ and the initiator 32 ″ described below.
[0083] The triggering device includes a striker and an initiator. The initiator can be used to drive the striker to move, so that the striker approaches the sealed container and punctures the sealed container. Alternatively, the initiator can also be used to drive the gas-generating device to move, so that the gas-generating device approaches the striker, thereby achieving the striker puncturing the sealed container. Alternatively, the initiator can also be used to simultaneously drive the striker and the gas-generating device to move, so that the gas-generating device and the striker approach each other until the striker punctures the sealed container, which is conducive to increasing the triggering speed. As long as the striker and the sealed container gradually approach each other, the striker can use the tip of the striker to quickly puncture the sealed container without generating sparks, making it safe to use and having high opening efficiency.
[0084] Of course, the triggering device is not limited to the above solution. For example, the triggering device may include a cutter and a motor, wherein the motor drives the cutter to cut the sealed container, thereby opening the sealed container; or the triggering device may include a small electric drill, which is used to open the sealed container.
[0085] The initiator may include an electrical initiator and / or a thermal initiator.
[0086] In an illustrative example, the driving medium is a gaseous medium.
[0087] The driving medium can be a gaseous medium stored in a sealed container and ejected quickly when the sealed container is opened. The driving medium can be nitrogen, argon, carbon dioxide, air, etc., with a pressure level higher than 1.2 MPa.
[0088] In another illustrative example, the driving medium is a liquid medium.
[0089] The driving medium can also be a liquid medium that can be encapsulated in a sealed container in liquid form and vaporizes into gas and ejected after the sealed container is opened, such as liquid carbon dioxide, liquid propane, etc. In other words, the driving medium is a medium that can be converted from liquid to gas.
[0090] Alternatively, the driving medium can be a solid medium, encapsulated in a sealed container in solid form, which sublimates into a gas upon opening the container, such as solid carbon dioxide (dry ice). In other words, the driving medium is a solid-to-gas medium that is directly converted to a gas by depressurizing the sealed container, rather than generating gas through combustion or explosion. Therefore, the gas-generating device remains a non-explosive device.
[0091] Alternatively, the driving medium may include any combination of a gaseous medium, a liquid medium, and a solid medium. In other words, the driving medium may include a gaseous medium and a liquid medium. Alternatively, the driving medium may include a gaseous medium and a solid medium. Alternatively, the driving medium may include a liquid medium and a solid medium. Alternatively, the driving medium may include a gaseous medium, a liquid medium, and a solid medium. As long as the two or three media in different states sealed in the sealed container do not react with each other and can all be ejected in a gaseous form after the sealed container is opened, it will suffice.
[0092] Two specific examples of fire extinguishing devices are described below with reference to the accompanying drawings.
[0093] Specific Example 1
[0094] like Figure 4 As shown, 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 ′ is filled with a gas fire extinguishing agent.
[0095] like Figure 3 As shown, the starting device 100' includes: a housing 1', a gas generating device 2', a triggering device 3', a sealing valve 4', a siphon tube 5' and an elastic member 6'. The housing 1' includes: an outer shell 11', a sealing cover 14', a sealing plug 12' and a support base 13'. Figure 5 As shown, the gas generating device 2' includes a sealed container and a driving medium encapsulated in the sealed container. The triggering device 3' includes a striker 31' and an initiator 32'. The initiator 32' is an electric initiator. The elastic member 6' is a compression spring.
[0096] The shell 11' is provided with a first installation cavity 111', a second installation cavity 112', a third installation cavity 113', an avoidance cavity 117' and a fourth installation cavity 114'. The sealing plug 12' is provided in the first installation cavity 111', and the support seat 13' is provided in the second installation cavity 112'. The support seat 13' is provided with an avoidance hole 133' and a mounting hole 131'. The striker 31' includes a sliding portion 311' and a puncture portion 312'. The sliding portion 311' is located in the first installation cavity 111' and slidably cooperates with the shell 11'. The puncture portion 312' is inserted into the avoidance hole 133'. A sealed cavity 1111' is formed between the sealing plug 12' and the striker 31'. The sealed container includes a head and a body. The head is installed in the mounting hole 131', and the body is inserted into the fire extinguishing agent storage container 210'. The support seat 13' is also provided with four air passages 132'. The sealing valve 4' is installed in the third installation cavity 113'. The sealing cover 14' is partially inserted into the fourth installation cavity 114', thereby sealing the fourth installation cavity 114'. The sealing cover 14' is provided with a retaining groove 141'. A portion of the compression spring is inserted into the retaining groove 141', while the other portion passes through the avoidance cavity 117' and abuts against the sealing valve 4'. The housing 11' is also provided with a discharge channel 116' and a nozzle 115'. One end of the siphon tube 5' is inserted into the discharge channel 116', and the other end of the siphon tube 5' is inserted into the fire extinguishing agent storage container 210'.
[0097] The sealing cap 14' is threadedly secured to the housing 11'. The siphon tube 5' is threadedly secured to the housing 11'. The support base 13' is threadedly secured to the housing 11'. The sealing valve 4' is a metal component, fitted with an O-ring. The striker 31' is also a metal component, fitted with two O-rings. The sealing plug 12' is a silicone component.
[0098] The electric initiator has a starting current of 225mA to 600mA, a safety current of 200mA, and a resistance of 4.5Ω±0.5Ω.

There is no pressure gauge on the starting device 100' or the fire extinguishing agent storage container 210'. The nozzle 115' is a three-channel structure and is connected to the siphon tube 5'.
[0100] However, when the connecting line 322' of the electric initiator is connected to the power supply, the resistor 321' generates heat, causing the air pressure in the sealed chamber 1111' to increase, squeezing the striker 31' to pierce the sealed container of the degassing device 2'. The nitrogen in the sealed container enters the fire extinguishing agent storage container 210' through the gas passage 132', and squeezes the HFC-227ea fire extinguishing agent in the fire extinguishing agent storage container 210' into the siphon tube 5', lifting the sealing valve 4' and spraying it out from the nozzle 115'.
[0101] Specific Example 2
[0102] like Figure 6 As shown, 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 ″ is filled with a gas fire extinguishing agent.
[0103] like Figure 5 As shown, the starting device 100" includes: a shell 1", a gas producing device 2", and a triggering device 3". The shell 1" includes a first outer shell 11" and a support seat 12". The support seat 12" and the first outer shell 11" enclose a sealed cavity 13". The first outer shell 11" includes a shell body 111", a first cover 112" and a sealing assembly 113". The sealing assembly 113" includes a second cover 1131", a sealing plug 1132" and a first sealing diaphragm 1133". The two ends of the shell body 111" form a first mounting port 1111" and a second mounting port 1112". The gas producing device 2" and the striker 31" are located in the shell body 111". The support seat 12" is installed at the first mounting port 1111". The sealing plug 1132" is installed at the second mounting port 1112", and the sealing plug 1132" is provided with an air passage 1135". The first cover 112 ″ and the second cover 1131 ″ are both threadedly connected to the housing 111 ″. The first sealing membrane 1133 ″ is clamped by the second cover 1131 ″ and the housing 111 ″.
[0104] The gas production device 2" includes a sealed container and a driving medium encapsulated in the sealed container. The driving medium is liquid carbon dioxide.
[0105] The initiator 3" includes a striker 31" and an initiator 32". The initiator 32" is an electric initiator. The resistor 321" of the electric initiator is located in the sealing groove 1121". The connecting wire 322" of the electric initiator passes through the first cover 112" and extends to the outside of the first cover 112".
[0106] The fire extinguishing agent storage container 210" includes a second shell 2102" and a third cover 2104". The second shell 2102" is provided with a first opening 2108" and a second opening 2110". The starting device 100" is installed at the first opening 2108" and is located inside the second shell 2102". The third cover 2104" is installed at the second opening 2110" and is located in the mounting groove 2114". A second sealing diaphragm 2112" is sandwiched between the third cover 2104" and the groove wall of the mounting groove 2114". The third cover 2104" is provided with a fire extinguishing agent nozzle 2106".
[0107] There is no pressure gauge on the starting device 100" and the fire extinguishing agent storage container 210".
[0108] When a fire occurs, after the connecting line 322" of the electric initiator is connected to the power supply, the resistor 321" heats up, causing the air pressure in the sealed chamber 13" to increase, and the support seat 12" moves under force, driving the gas production device 2" to move towards the direction of the striker 31", causing the striker 31" to pierce the sealed container, and the gas in the sealed container breaks through the first sealing membrane 1133" through the air passage 1135" and sprays out. The fire extinguishing agent 220" in the fire extinguishing agent storage container 210" is squeezed to break through the second sealing membrane 2112" and spray out.
[0109] In the above embodiment, the fire extinguishing device 1 is a non-pressure storage type fire extinguishing device with its own gas generating device, and the gas generating device is not a pyrotechnic product.
[0110] Of course, the fire extinguishing device 1 may also be a conventional stored-pressure fire extinguishing device, a non-stored-pressure fire extinguishing device with its own gas generating device and the gas generating device being an pyrotechnic device, or other types of fire extinguishing devices. As they do not deviate from the design concept and purpose of this application, they are all within the scope of protection of the present invention.
[0111] like Figure 2 As shown, an embodiment of the present invention further provides a vehicle, comprising: a vehicle body and a fire extinguishing device 100 as any one of the embodiments of the first aspect, arranged in the vehicle body.
[0112] The vehicle provided by the embodiment of the present invention includes the fire extinguishing device 100 of any one of the above embodiments, and thus has all the beneficial effects of any of the above embodiments, which will not be described in detail here.
[0113] Furthermore, if a vehicle catches fire, the user can throw the second delivery pipe 3 out of the vehicle and escape. When the fire truck arrives, it can connect to the second delivery pipe 3 via the fire interface 4 and effectively and accurately extinguish the fire at the fire site. The user can also find a nearby fire hydrant and connect it to the second delivery pipe 3 via the fire interface 4, enabling timely firefighting and rescue efforts.
[0114] In an exemplary embodiment, the vehicle body includes an enclosed space (for details, refer to the interior space of the battery pack 110 and the interior space of the engine compartment described below). The outlet of the first delivery pipeline 2 of the fire extinguishing device 100 is connected to the enclosed space, and the detector 8 of the fire extinguishing device 100 is disposed in the enclosed space.
[0115] By locating the outlet of the first delivery pipeline 2 and the detector 8 within the enclosed space, fires within the enclosed space can be detected promptly, allowing for precise and efficient fire extinguishing of the structures within the enclosed space. Compared to extinguishing fires from outside the enclosed space, the fire extinguishing agent of the fire extinguishing device 1 and the fire extinguishing medium of the external firefighting equipment are both delivered directly into the enclosed space, precisely extinguishing the fire directly at the location within the enclosed space. This results in more efficient and reliable fire extinguishing.
[0116] It is worth noting that in the prior art, when a fire breaks out inside a vehicle, the vehicle's personnel can generally only wait for the fire truck to arrive. After the fire truck arrives, it extinguishes the fire from the outside of the vehicle and cannot directly act on the fire point inside the vehicle, resulting in a long fire extinguishing time and low fire extinguishing efficiency. However, after adopting the fire extinguishing equipment of the present application, the vehicle's personnel can throw the second delivery pipeline outside the vehicle when abandoning the vehicle to escape. After the fire truck arrives, it can be connected to the fire interface 4, and then the fire extinguishing medium can be directly sprayed onto the fire point in the enclosed space, achieving efficient and rapid fire extinguishing. In addition, before the fire truck arrives, the vehicle's personnel can also check whether there are fire hydrants or other external fire-fighting equipment nearby, or use fire hydrants or other external fire-fighting equipment nearby to promptly extinguish the fire point in the vehicle. Therefore, this solution can significantly improve the fire extinguishing efficiency of the vehicle, which is beneficial for reducing the risk of mass deaths and injuries caused by vehicle fires and also helps to reduce property losses.
[0117] In an exemplary embodiment, the enclosed space includes the interior space of the battery pack 110 box and / or the interior space of the engine compartment.
[0118] Battery packs 110 are prone to thermal runaway and fire, so the fire extinguishing device 100 of the present application facilitates efficient and accurate fire extinguishing of the battery packs 110, thereby improving vehicle safety. The number of battery packs 110 can be one or more. Each battery pack 110 is equipped with a detector 8.
[0119] The engine is also a part that is prone to overheating and fire. Therefore, the use of the fire extinguishing device 100 of the present application is also conducive to efficient and accurate fire extinguishing of the engine, thereby improving the safety of the vehicle.
[0120] Of course, the enclosed space is not limited to the above-mentioned space, and can be arranged as needed during the actual production process.
[0121] In an exemplary embodiment, the second delivery line 3 is placed in the cockpit.
[0122] This makes it easy for the personnel in the vehicle to find the second delivery pipeline quickly and throw it outside the vehicle. Of course, the second delivery pipeline 3 can also be placed on other parts of the vehicle body.
[0123] Of course, the fire extinguishing equipment 1 of the present application can be used not only in vehicles, but also in other places, such as gas stations, machine rooms, charging stations, etc.
[0124] In summary, the fire-fighting equipment and vehicle provided in the embodiments of the present invention, by providing a second delivery pipeline and a fire interface, enable the fire-fighting equipment to be connected to external fire-fighting equipment, such as a fire truck or fire hydrant. This allows fire-fighting water and other extinguishing media from the external fire-fighting equipment to enter the first delivery pipeline through the second delivery pipeline and be continuously delivered to the fire site, effectively extinguishing the fire there. This improves firefighting effectiveness and reduces the risk of mass casualties from fires.
