Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a fire extinguishing device and a method for extinguishing fires in vehicles. Background Technology

[0002] Currently, the mainstream cars on the market include new energy vehicles and conventional energy vehicles, both of which have the risk of catching fire.

[0003] Taking new energy vehicles as an example, they mainly include three types: pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles. New energy vehicles have advantages such as environmental friendliness, energy conservation, and high efficiency. They can effectively reduce dependence on traditional fuels, lower exhaust emissions, and alleviate energy crises and environmental pollution problems, making them an important direction for the future development of the automotive industry. With continuous technological advancements and strong policy support, the market share of new energy vehicles is gradually increasing, and their presence in daily life is also gradually expanding.

[0004] For pure electric vehicles and hybrid vehicles, they usually have a power battery that can be charged by an external power source. When the electric vehicle is parked, there is a possibility that the battery will thermally run away and catch fire. Because the battery burns quickly, while waiting for the fire department to arrive, the flames may spread to surrounding vehicles or other flammable materials, causing a larger fire. Summary of the Invention

[0005] The main objective of this invention is to provide a fire extinguishing device and a vehicle fire extinguishing method, aiming to provide a fire extinguishing device that can be placed in a parking lot to extinguish a vehicle fire at the first moment.

[0006] To achieve the above objectives, the fire extinguishing device proposed in this invention includes: A movable component, wherein the upper top surface of the movable component forms a mounting plane; A housing, disposed on the mounting plane, and enclosing a cavity with the mounting plane; and The shed includes a telescopic frame and a fireproof blanket. The telescopic frame is located on one side of the shell and can be extended and retracted. The fireproof blanket is located on the telescopic frame and can be deployed through the telescopic frame to form an isolation space. The canopy is equipped with a delivery device on the side facing the isolation space, and the fireproof blanket is placed on the delivery device and can be released from the delivery device to detach from the telescopic frame.

[0007] In one embodiment, the telescopic frame includes: Multiple gantry cranes, with the multiple gantry cranes spaced apart; A scissor lift structure, comprising two scissor arms connected to each of two adjacent gantry frames, each scissor arm having a fixed end and a movable end, the fixed end being fixedly connected to one gantry frame and the movable end being slidably connected to the other adjacent gantry frame; and An electric actuator is mounted on the gantry frame, and the drive end of the electric actuator is connected to the movable end of the scissor arm. Among them, the two ends of the gantry frames away from the housing are provided with support wheels, which are used to abut against the ground.

[0008] In one embodiment, the delivery device includes a mounting frame and an electromagnet. The mounting frame is mounted on the gantry frame, and the electromagnet is located on the side of the mounting frame facing away from the gantry frame. The outer top surface of the fire blanket is provided with a magnetic conductive element, which is magnetically attracted to the electromagnet. The fire extinguishing device includes multiple delivery devices, which are staggered along the arrangement direction of the gantry frame.

[0009] In one embodiment, the fire extinguishing device further includes a spray assembly comprising a water tank and a nozzle, the water tank being disposed in the receiving cavity, and the nozzle communicating with the water tank and exposed in the housing towards the isolation space.

[0010] In one embodiment, the nozzle is located below one side of the housing, and the nozzle has a nozzle that is oriented obliquely upward.

[0011] In one embodiment, the fire extinguishing device further includes an air purification component, which includes a purifier and an air inlet pipe. The purifier is connected to the air inlet pipe, and the air inlet pipe has an air inlet that is exposed in the housing and connected to the isolation space.

[0012] In one embodiment, the mobile component includes a chassis, two drive wheels, and two steering wheels. The chassis has a top surface and a bottom surface that are disposed opposite to each other. The housing is disposed on the top surface, the two drive wheels are disposed on the bottom surface and located on the same axis, and the two steering wheels are rotatably disposed on the bottom surface.

[0013] In one embodiment, the fire extinguishing device further includes a generator, which is disposed in the accommodating cavity and electrically connected to the movable component, the telescopic frame, and the delivery device.

[0014] The present invention also proposes a vehicle fire extinguishing method, applied to the fire extinguishing device described above, comprising: The area where the fire occurred was confirmed based on the obtained fire information; Control the fire extinguishing device to move to the area where the fire occurred; The telescopic frame is extended to position the burning vehicle within the isolation space. Control the delivery device to release the fire blanket.

[0015] In one embodiment, the method further includes the following steps before the step of controlling the release device to release the fire blanket: Fire extinguishing agent is sprayed into the isolated space.

[0016] The present invention provides a fire extinguishing device and a method for extinguishing vehicle fires. The fire extinguishing device includes a movable component, a housing, a canopy, and a dispensing device. The housing is located on the mounting plane of the movable component and forms a cavity around the mounting plane. The canopy is located on one side of the housing and includes a telescopic frame and a fire blanket. The fire blanket is mounted on the telescopic frame via the dispensing device. The telescopic frame can extend or retract relative to the housing, thereby causing the fire blanket to extend or retract. When a fire occurs, the fire extinguishing device can be moved to the location of the fire via the movable component, providing high flexibility. The extension of the telescopic frame causes the fire blanket to unfold, creating an isolation space within which the burning vehicle is completely contained. The dispensing device releases the fire blanket to cover the burning vehicle, preventing the fire from spreading to nearby parked vehicles or other flammable and explosive materials, thus reducing economic losses.

[0017] Moreover, completely covering the burning vehicle with a fire blanket can prevent external oxygen from participating in the combustion. When the oxygen inside the fire blanket is exhausted, the combustion will also stop quickly, improving the overall emergency response capability for fires. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0024] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] Currently, the mainstream automobiles on the market include both new energy vehicles and conventional energy vehicles, both of which carry the risk of fire. For example, when a gasoline-powered vehicle is parked, malfunctions or defects in certain components or systems can lead to fuel leaks, short circuits, or overheating, which can easily ignite when exposed to high temperatures or open flames. Electrical system malfunctions can cause short circuits, generating sparks or overheating, which can then ignite surrounding flammable materials. Engine overheating or cooling system malfunctions can also raise the temperature inside the engine compartment, increasing the risk of spontaneous combustion. Furthermore, if flammable items such as lighters or perfumes are stored in the vehicle, they can also ignite in high-temperature environments.

[0026] For example, thermal runaway of the battery during parking or charging of an electric vehicle can also lead to spontaneous combustion. The causes of battery thermal runaway can be broadly categorized into charging-related issues, driving-related issues, vehicle-related issues, and external factors. For instance, fast charging generates significant and uneven heat in a short period; if the battery reaches the initiation temperature for thermal runaway, it may spontaneously combust. Furthermore, overcharging, battery management system (BMS) malfunctions, substandard battery cells, and aging circuitry can also lead to thermal runaway. Additionally, unauthorized modifications to the electrical system or the installation of high-power equipment can cause circuit overload and spontaneous combustion. Extreme temperature conditions, improper charging operations, or vehicle collisions can all damage the battery, increasing the risk of spontaneous combustion.

[0027] To address the aforementioned problems, this invention proposes a fire extinguishing device 100, which aims to provide a fire extinguishing device 100 that can be placed in a parking lot and extinguish a vehicle fire at the first moment. Figures 1 to 10 This is a schematic diagram of an embodiment of the fire extinguishing device 100 of the present invention.

[0028] Please refer to Figures 1 to 10The present invention proposes a fire extinguishing device 100, including a movable component 1, a housing 2, and a canopy 3. The upper top surface of the movable component 1 forms an installation plane, the housing 2 is disposed on the installation plane and surrounds the installation plane to form a receiving cavity; the canopy 3 includes a telescopic frame 31 and a fire blanket 32. The telescopic frame 31 is disposed on one side of the housing 2 and can be extended and retracted, and the fire blanket 32 ​​is disposed on the telescopic frame 31 and can be unfolded through the telescopic frame 31 to form an isolation space 3a.

[0029] Understandably, this fire extinguishing device 100 is generally suitable for handling fires involving small and micro passenger vehicles. Since the canopy 3 needs to completely cover the burning vehicle to prevent the fire from spreading, its unfolded dimensions should be slightly larger than those of commonly seen small and micro passenger vehicles to ensure complete coverage. Generally, small and micro passenger vehicles are approximately 3.5 to 4.5 meters long, 1.6 to 1.8 meters wide, and 1.4 to 1.6 meters high. Therefore, the unfolded dimensions of the canopy 3 can be designed to be approximately 5 meters long, 2 meters wide, and 2 meters high, leaving sufficient margin to ensure complete coverage of the burning vehicle and provide a certain isolation space 3a. Furthermore, according to national standards, the height of underground parking garages must not be less than 2 meters. Therefore, the fire extinguishing device 100 proposed in this application can be used not only in surface parking lots but also in underground parking lots, expanding its application scenarios and improving its practicality. Considering the differences in vehicle size, the telescopic frame 31 of the canopy 3 can be designed to be adjustable to accommodate vehicles of different sizes.

[0030] The present invention provides a fire extinguishing device 100 and a method for extinguishing vehicle fires. The fire extinguishing device 100 includes a movable component 1, a housing 2, a canopy 3, and a dispensing device 4. The housing 2 is located on the mounting plane of the movable component 1 and forms a cavity with the mounting plane. The canopy 3 is located on one side of the housing 2 and includes a telescopic frame 31 and a fire blanket 32. The fire blanket 32 ​​is mounted on the telescopic frame 31 via the dispensing device 4. The telescopic frame 31 can extend or retract relative to the housing 2, thereby causing the fire blanket 32 ​​to extend or retract. When a fire occurs, the fire extinguishing device 100 can be moved to the location of the fire via the movable component 1, providing high flexibility. The extension of the telescopic frame 31 causes the fire blanket 32 ​​to unfold, forming an isolation space 3a within it. The burning vehicle is completely contained within this isolation space 3a. The dispensing device 4 releases the fire blanket 32 ​​to cover the burning vehicle, preventing the fire from spreading to nearby parked vehicles or other flammable and explosive materials, thus reducing economic losses. Moreover, the fire blanket 32 ​​completely covers the burning vehicle, which can also prevent external oxygen from participating in the combustion. When the oxygen inside the fire blanket 32 ​​is exhausted, the combustion will also stop quickly, improving the overall emergency response capability for fires.

[0031] It should be noted that the telescopic frame 31 in the shed 3 can be a multi-link structure or a scissor telescopic structure. This application does not limit this. In one embodiment of this application, the telescopic frame 31 includes multiple gantry frames 311 and a scissor structure. The multiple gantry frames 311 are arranged sequentially and evenly from the end closest to the shell 2 to the end furthest from the shell 2. For details, please refer to further reading. Figures 2 to 4 A scissor structure is provided between every two adjacent gantry frames 311. The scissor structure consists of two intersecting scissor arms 312, each scissor arm 312 being connected to the vertical rods of the two gantry frames 311 respectively. In order to ensure both the extension and retraction of the gantry frames 311 and to limit their movement, each scissor arm 312 has a fixed end 312a and a movable end 312b at its two ends. The fixed end 312a can be on top and the movable end 312b can be on the bottom, or the fixed end 312a can be on the bottom and the movable end 312b can be on top. In this embodiment, the fixed end 312a of each scissor arm 312 is on top and the movable end 312b is on the bottom. The scissor arm 312 is hinged to an adjacent gantry 311 via a fixed end 312a, while the movable end 312b is slidably connected to another adjacent gantry 311. When the movable end 312b slides on the gantry 311, the angle between the scissor arm 312 and the plane containing the two gantry 311 changes, thereby adjusting the distance between the two gantry 311 and enabling the unfolding and storage of the fire blanket 32.

[0032] Furthermore, the telescopic frame 31 can operate automatically or manually; this application does not impose any limitations on this. In one embodiment of this application, the telescopic frame 31 unfolds and retracts automatically. Specifically, the telescopic frame 31 also includes an electric actuator 313; for further details, please refer to [link to relevant documentation]. Figure 4An electric actuator 313 is mounted on the gantry 311. The drive end of the electric actuator 313 is connected to the movable end 312b of the scissor arm 312. Since the movable end 312b of the scissor arm 312 is located at its lower end, the drive end of the electric actuator 313 is set downwards. Therefore, when the telescopic frame 31 is in the retracted state, the electric actuator 313 is in the extended state. When it is necessary to drive the telescopic frame 31 to unfold, the electric actuator 313 retracts inwards, causing the movable end 312b of the scissor arm 312 to move upwards, thereby increasing the angle between the scissor arm 312 and the plane of the adjacent gantry 311, thus widening the distance between the two adjacent gantry frames 311. Using an electric actuator 313 to drive the telescopic frame 31 enables automated operation, making the entire fire extinguishing process faster and more efficient. Secondly, the electric actuator 313 provides precise control, ensuring the fire blanket accurately covers the target area. Furthermore, its simple operation and ease of remote or automatic control increase flexibility. Simultaneously, the electric actuator 313 is reliable in structure, easy to maintain, has a long service life, can withstand heavy loads, and adapts to various working environments. Improving the automation level of the equipment reduces human intervention and can also prevent injuries to personnel during fires, lowering overall safety hazards. It should be noted that, in addition to using an electric actuator 313 to drive the telescopic frame 31, cylinders, lead screws, sliders, and other driving structures can also be used to drive the telescopic frame 31. This application does not limit this; anything within the technical concept of this invention is included within the scope of patent protection of this invention.

[0033] In the technical solution of this application, when a fire occurs and the burning vehicle is completely within the isolation space 3a, the unfolded fire blanket 32 ​​is deployed using the deployment device 4. This causes the fire blanket 32 ​​to detach from the telescopic frame 31 and fall under gravity until it completely covers the burning vehicle. It should be noted that the deployment device 4 can be an electromagnet 42, a mechanical gripper, or a spring-loaded launching device; this application does not limit this. In one embodiment of this application, the deployment device 4 includes a mounting frame 41 and an electromagnet 42. For further details, please refer to the following documentation. Figure 4 and Figure 5An electromagnet 42 is located on the side of the mounting frame 41 facing away from the gantry frame 311. A magnetic guide 321 is provided on the outer top surface of the fire blanket 32, and the magnetic guide 321 is magnetically attracted to the electromagnet 42. The mounting frame 41 is welded to the crossbeam of the gantry frame 311 and faces downwards. The working principle of the electromagnet 42 dispensing device 4 is based on the electromagnetic effect. A magnetic field is generated by current to attract and release the magnetic guide 321 on the fire blanket 32. When fire extinguishing is required, the power supply to the electromagnet 42 is stopped, the magnetic field disappears, and the fire blanket 32 ​​detaches from the telescopic frame 31 and falls under the influence of gravity. Using an electromagnet 42 as the dispensing device 4 has advantages such as rapid response, high control precision, simple structure, high reliability, strong environmental adaptability, high safety, and ease of automation. These characteristics make the electromagnet 42 dispensing device 4 very suitable for use in the fire extinguishing device 100 to achieve rapid, accurate, and safe dispensing of the fire blanket 32 ​​to control and extinguish vehicle fires.

[0034] In one embodiment of this application, to further optimize the structure of the device and make the force distribution between the various structures more balanced, support wheels 33 are provided at the bottom of the two vertical rods of the gantry 311 at one end of the outermost housing 2. For details, please refer to the following document. Figure 3 Firstly, the support wheel 33 can effectively distribute and balance the weight and force of the device, reducing the pressure on the fixed point, thereby improving the stability and durability of the structure. Secondly, the support wheel 33 helps the device to move more smoothly during movement or extension, reducing friction and wear, and extending the service life of the device. In addition, the support wheel 33 can also make the device easier to move on uneven ground, improving the adaptability and flexibility of the device.

[0035] To further optimize the fire extinguishing effect, the fire extinguishing device 100 also includes a sprinkler assembly 5. For details, please refer to the relevant documentation. Figure 3 and Figure 7 The sprinkler assembly 5 includes a water tank 51 and nozzles 52. The water tank 51 is located within the housing cavity, and the nozzles 52 communicate with the water tank 51 and are exposed in the housing 2 facing the isolation space 3a. This design significantly improves fire extinguishing efficiency. The water tank 51 stores the fire extinguishing water, while the nozzles 52 ensure that the water is evenly distributed to all parts of the burning vehicle. This not only speeds up the extinguishing of the fire but also helps reduce water waste and potential secondary damage to the vehicle. Furthermore, the system improves operational safety and, through automated control, can work in conjunction with other functions of the device to adapt to different fire conditions, thereby enhancing the overall fire extinguishing effect and flexibility.

[0036] Furthermore, taking new energy vehicles as an example, the fire source is usually the power battery, which is typically located below or near the vehicle chassis 11. Therefore, in one embodiment of this application, to specifically extinguish the fire source, a nozzle 52 is located on the lower side of one side of the housing 2. The nozzle 52 has a nozzle 521, which is oriented diagonally upwards. For more details, please refer to the following documentation. Figure 10 This design allows for more precise application of the extinguishing agent to the fire site (11) on the vehicle's chassis, improving extinguishing efficiency and effectiveness. It also helps to quickly reduce battery temperature, preventing further thermal runaway. Furthermore, this layout reduces extinguishing agent waste, ensuring full utilization of extinguishing resources. In addition, targeted extinguishing methods can minimize potential damage to other parts of the vehicle, protecting its integrity.

[0037] In one embodiment of this application, the fire extinguishing device 100 further includes an air purification component 6, which includes a purifier 61 and an air inlet pipe 62. For details, please refer to further reading. Figure 8 The purifier 61 is connected to the air inlet pipe 62, which has an air inlet that is exposed in the housing 2 and connected to the isolation space 3a. The purifier 61 can effectively purify the smoke and harmful gases generated during the fire extinguishing process, reducing the impact on the surrounding environment and personnel health. Secondly, by purifying the air in the isolation space 3a, it helps to improve the fire extinguishing efficiency, because clean air can promote the cooling of burning materials. In addition, the air purification component 6 can also reduce the difficulty of cleanup after fire extinguishing, because particulate matter and toxic gases in the air are reduced.

[0038] To improve the flexibility of the fire extinguishing device 100, the mobile assembly 1 includes a chassis 11, two drive wheels 12, and two steering wheels 13. For details, please refer to further documentation. Figure 9 The chassis 11 has a top surface and a bottom surface arranged opposite each other. The housing 2 is located on the top surface, the two drive wheels 12 are located on the bottom surface and are on the same axis, and the two steering wheels 13 are rotatably located on the bottom surface. This design significantly improves the mobility and flexibility of the device. Specifically, this structure allows the fire extinguishing device 100 to respond quickly, easily move to the location of the fire, and flexibly adjust its direction to adapt to different on-site environments and needs. The use of the drive motor 121 also ensures that the movement of the device is more stable and controllable, improving fire extinguishing efficiency and accuracy. In addition, this design also helps to reduce manual operation, reduce the labor intensity of workers, and improve the safety of the fire extinguishing process.

[0039] In one embodiment of this application, the fire extinguishing device 100 integrates a generator 7, which is electrically connected to the mobile component 1, the telescopic frame 31, and the dispensing device 4. This ensures that the device can operate independently without an external power source, improving its applicability and flexibility in various environments. Secondly, the power provided by the generator 7 can support the operation of electric components such as the drive motor 121 and the electric actuator 313, enabling automated and intelligent operation of the device and improving fire extinguishing efficiency and response speed. Furthermore, the self-powered capability enhances the reliability of the device, allowing it to operate normally even in situations of unstable or interrupted power supply. Finally, this design simplifies the deployment and use of the device, eliminating the need for additional power connections and reducing the complexity of installation and maintenance, thereby improving the practicality and economy of the fire extinguishing device 100.

[0040] This invention also proposes a vehicle fire extinguishing method, which is applied to the fire extinguishing device 100 described above. The fire extinguishing method includes the following steps: S1: confirming the fire location based on the obtained fire information; S2: controlling the fire extinguishing device 100 to move to the fire location; S3: controlling the telescopic frame 31 to extend so that the burning vehicle is located within the isolation space 3a; S4: controlling the delivery device 4 to release the fire blanket 32. The specific structure of the fire extinguishing device 100 is as described in the above embodiments. Since this vehicle fire extinguishing method adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0041] In one embodiment of this application, before the step of controlling the release device 4 to release the fire blanket 32, the fire extinguishing medium is sprayed into the isolation space 3a. The fire extinguishing medium can be a foam extinguishing agent or water, and this application does not limit it.

[0042] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
