Description

Technical Field

[0001] The present invention relates to the field of electric vehicle fire extinguishing, and in particular to an electric vehicle fire extinguishing method and application. Background Art

[0002] With the promotion of electric vehicles, their ownership has increased rapidly, but the number of electric vehicle fire accidents has also increased. The biggest safety problem of electric vehicles is the problem of fire caused by leakage of wires, which is mainly concentrated in the motor compartment and battery compartment. In actual use, due to the limitations of the specific fire environment, such as insufficient fire extinguishing dosage and insufficient preparation of fire extinguishing equipment, the fire extinguishing effect of electric vehicles is often not ideal, and the battery is prone to reignition.

[0003] For example, the Chinese invention patent (application number: CN202111578571.X) discloses an "electric vehicle fire extinguishing device and electric vehicle equipped with the same." Its specification discloses: Recently, the number of battery-powered electric vehicles has steadily increased, and correspondingly, the number of electric vehicle fires caused by such devices has also increased. When an electric vehicle fire occurs, firefighters spray water inside the vehicle to extinguish the fire. However, there is a risk of batteries on the floor of the vehicle exploding and erupting into flames. Therefore, firefighters maintain a certain distance from the vehicle when spraying water. In this case, even if water is sprayed from the outside of the vehicle onto the battery casing, it is difficult for the water to penetrate the battery modules inside, and it takes a considerable amount of time for the battery modules to completely explode and be destroyed. Furthermore, when an electric vehicle fire occurs, some partially damaged battery cells within the battery pack may reignite, necessitating a solution to address electric vehicle fires. The aforementioned patent demonstrates the shortcomings of the existing technology.

[0004] Therefore, we make improvements to this and propose electric vehicle fire extinguishing method and application. Summary of the Invention

[0043] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0044] As electric vehicles are increasingly adopted and their number increases rapidly, they present a unique set of challenges in firefighting. Unlike traditional gasoline vehicles, electric vehicles have high-voltage batteries that can pose a fire risk if damaged. To address these challenges, some recommended solutions for electric vehicle firefighting include:

[0045] 1. Education and training: Firefighters should receive specialized training on electric vehicle technology and how to safely handle high-voltage battery systems. This training should include information on how to identify an electric vehicle, how to safely disconnect the battery, and how to extinguish an electric vehicle fire using water and foam.

[0046] 2. Protective gear: Firefighters should also be provided with appropriate protective gear, including gloves, helmets, and other personal protective equipment (PPE) to prevent electrical shock and burns.

[0047] 3. Infrared thermal imaging cameras: Infrared thermal imaging cameras can be used to locate hot spots within a vehicle’s battery system and help firefighters determine the best strategy for extinguishing the fire.

[0048] 4. Specialized fire extinguishing agents: Firefighters may also need to use specialized fire extinguishing agents to extinguish electric vehicle fires. For example, a Class D fire extinguisher can be used to control a lithium-ion battery fire.

[0049] 5. Evacuation Procedures: If an electric vehicle fire occurs, firefighters should ensure the safety of all occupants and take necessary measures to evacuate quickly.

[0050] 6. Battery Disconnection Procedures: Firefighters should be trained to disconnect the battery before attempting to extinguish an electric vehicle fire, as this helps reduce the risk of electric shock.

[0051] 7. Storage and Disposal: Once the fire is extinguished, damaged batteries should be placed in metal containers and stored in an isolated area until they can be safely disposed of.

[0052] In summary, EV firefighting solutions include educating firefighters on EV technology, providing them with appropriate protective gear, using thermal imaging cameras to locate hot spots, using specialized extinguishing agents, and implementing evacuations.

[0053] However, when actually extinguishing a fire in an electric vehicle, as described in the background art, due to the limitations of the specific fire environment, such as insufficient fire extinguishing dosage and insufficient preparation of fire extinguishing equipment, the fire extinguishing effect on the electric vehicle is often less than ideal, and the battery is prone to reignition.

[0054] In order to solve this technical problem, the present invention provides an electric vehicle fire extinguishing method, which is applied to extinguishing fire of electric vehicle batteries.

[0055] Specifically, please refer to Figure 1 , electric vehicle fire extinguishing methods specifically include:

[0056] 1. Use fire extinguishing cloth to cover and aerosol to extinguish the fire. First, cover the electric vehicle with fire extinguishing cloth to isolate the flame and air. Then spray aerosol fire extinguishing agent on the part of the electric vehicle on fire inside the fire extinguishing cloth to achieve the purpose of extinguishing the fire.

[0057] 2. Use a manually operated water mist gun to spray water at the fire site of the electric vehicle to form a layer of water mist covering the fire source, reducing the temperature around the fire source, absorbing heat, and diluting oxygen to achieve the purpose of extinguishing the fire;

[0058] 3. Use the drilling equipment to drill one or more holes on the battery, then align the nozzle of the water pipe with the water injection hole and inject water into the battery to extinguish the fire;

[0059] 4. Extinguish the fire by means of fencing and pouring water. Place a fence around the electric vehicle, pour water into the fence and make the water surface submerge the part of the electric vehicle where the fire broke out, so as to achieve the purpose of extinguishing the fire.

[0060] The electric vehicle fire extinguishing method provided by the present invention can selectively extinguish fires according to different situations by providing four fire extinguishing methods. Among them, extinguishing fires by fencing and pouring water can save water resources and prevent batteries from reigniting.

[0061] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0062] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0063] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. Example

[0064] Please refer to Figure 2-Figure 3 , electric vehicle fire extinguishing method, which uses enclosure and water injection to extinguish fire specifically includes the following four steps:

[0065] Step 1: Before placing the fence, pay attention to the ground conditions of the electric vehicle parking area, pay attention to whether there are potholes on the ground, and choose a reasonable fence placement area;

[0066] Step 2: Quickly place barriers around the burning electric vehicle;

[0067] Step 3: After properly placing the enclosure in step 2, quickly walk around the enclosure to check for leaks, that is, whether there is a clear gap between the enclosure and the parking surface;

[0068] Step 4: Place the drain pipe into the enclosure and start filling with water.

[0069] Specifically, in step 1, when laying the fence, firefighters need to wear fireproof clothing and pay attention to fire safety.

[0070] Specifically, when observing the fence in step three, a quick scanning method is used.

[0071] Specifically, when a leak is found, some fillers should be used to fill the gap.

[0072] Specifically, some small sandbags should be prepared in advance to fill the locations where there are still leaks after the fences are placed reasonably. When filling the fences with water, pay attention to whether there are any leaks. If there are any, immediately fill them with sandbags to avoid wasting water resources and affecting the fire-fighting effect. Example

[0073] For electric vehicle fire extinguishing applications, please refer to Figure 2-Figure 3Specifically, the fence includes a rectangular frame 1 formed by a pair of long baffles 101 and a pair of short baffles 102. The long baffles 101 and the short baffles 102 are both made of steel plates coated with a layer of anti-rust paint. The tops of the long baffles 101 and the short baffles 102 are provided with handles 104 for easy removal and movement. When a fire occurs in an electric vehicle, firefighters can quickly surround the electric vehicle. The connection between the long baffle 101 and the adjacent short baffles 102 is fixed and in close contact by fasteners 105. The fasteners 105 are such as common latches. Because the long baffles 101 and the short baffles 102 themselves have a certain weight, they are not easy to loosen when they are placed. By tightening The fasteners 105 complete the fixation after the long baffle 101 and the short baffle 102 are in contact, and the butt ends of the long baffle 101 and the short baffle 102 are in close contact. At the same time, before production, a layer of rubber sheet can be pasted on the butt ends of the long baffle 101 and the short baffle 102 to improve the sealing effect after the butt joint. The bottom ends of the long baffle 101 and the short baffle 102 are adapted to be provided with rubber bottom strips 103. When the long baffle 101 and the short baffle 102 are placed, the weight of the long baffle 101 and the short baffle 102 themselves makes the rubber bottom strips 103 in close contact with the parking surface to avoid water leakage, thereby forming a water injection pool between the rectangular frame 1 and the parking surface, and water can be poured into the water injection pool through a water pipe to complete the fire extinguishing of the burning vehicle. Example

[0074] Electric vehicle fire extinguishing application, different from the previous embodiment, the enclosure can also be used in parking lots, specifically, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, it also includes a spray mechanism installed on both sides of the frame 1. When the electric vehicle catches fire, the control system 2 controls the operation of the spray mechanism to quickly extinguish the fire.

[0075] Specifically, the spray mechanism includes a water injection pipe 3 provided on the frame 1, a U-shaped pipe 301 connected to the water injection pipe 3 is provided on the inner side of the frame 1, and the two ends of the U-shaped pipe 301 are connected to the spray pipe 302 through a rotating connector. The rotating connector is a conventional pipe connection device and is not described in detail here. A plurality of vertical spray parts 303 are equidistantly provided on the spray pipe 302, and a linkage assembly 304 is provided at the end of the spray pipe 302. The spray part 303 includes a cylinder 3031, and the two ends of the cylinder 3031 are respectively connected to the spray pipe 302, and the bottom of the cylinder 3031 is connected to the bottom of the cylinder 3031. The end is connected to a nozzle 3032, and a spray disc 3033 is rotatably arranged inside the nozzle 3032. The spray disc 3033 has several through holes 3034. A rotating shaft 3035 is coaxially arranged in the middle of the cylinder 3031. The bottom end of the rotating shaft 3035 is fixed to the spray disc 3033. The top of the rotating shaft 3035 is provided with a turbine 3036 opposite to the spray pipe 302. The turbine 3036 is driven by water flow to rotate, and then the rotating shaft 3035 and the spray disc 3033 are driven to rotate synchronously, so that water is sprayed from the through holes 3034 over a wider range, and the fire extinguishing effect on electric vehicles is better.

[0076] The electric vehicle further includes a control system 2, which includes a single-chip microcomputer installed on the frame 1, a fire sensing device provided on the frame 1 and electrically connected to the single-chip microcomputer, an electromagnetic valve provided on the water injection pipe 3 and electrically connected to the single-chip microcomputer, and a driving member provided on the frame 1 and electrically connected to the single-chip microcomputer. The bottom of one short baffle 102 is rotatably connected to the parking surface and driven by the driving member. When a fire occurs in the electric vehicle, the fire sensing device detects a fire signal and controls the driving member to drive the short baffle to rotate until it closes with the long baffle to form a water injection pool. The corresponding linkage assembly 304 includes a sleeve provided on the spray pipe 3 02 end and performs linear motion of the sleeve 3041, the outer end of the sleeve 3041 extends to the outside of the frame 1, an arc-shaped slide groove 3042 is provided on the spray pipe 302, and the inner wall of the sleeve 3041 is provided with a slider 3043 embedded in the arc-shaped slide groove 3042. An elastic member 3044 is also provided between the sleeve 3041 and the spray pipe 302. When the driving member drives the short baffle 102 to rotate, it drives the sleeve 3041 to move toward the spray pipe 302. Through the restriction of the arc-shaped slide groove 3042, the spray member 303 is rotated from a vertical state to a horizontal state, and starts to spray water. Example

[0077] The electric vehicle fire extinguishing application provided in Example 3 is further optimized. Specifically, Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 10 As shown, it also includes smoke treatment mechanisms installed on both sides of the frame 1. When the electric vehicle catches fire, the intelligent control system 2 controls the smoke treatment mechanism to operate to achieve the purpose of smoke removal.

[0078] Specifically, the smoke treatment mechanism includes a group of exhaust fans 4 symmetrically arranged on the top of both sides of the frame 1. The ends of the exhaust fans 4 are connected to the smoke treatment devices 402 through connecting pipes 403. The smoke treatment equipment 402 is a conventional air purification equipment, which can absorb some carbon dioxide and other substances in the smoke when the electric vehicle catches fire. The specific principle is not described here. The smoke treatment equipment 402 is installed at the end of the frame and can absorb and treat the smoke generated when the electric vehicle catches fire, reduce air pollution, and reduce the hidden dangers of workers accidentally inhaling smoke and endangering their health.

[0079] Furthermore, the drive shaft 404 of the exhaust fan 4 extends to the outside of the exhaust fan 4, and a transmission shaft 405 is provided on the frame 1. The inner end of the transmission shaft 405 is provided with a first clamping block 406. The outer end of the transmission shaft 405 is transmitted to the drive shaft 404 of the exhaust fan 4 through a transmission member 407. The top of the rotating shaft 3035 extends to the outside of the cylinder 3031 and is connected to the second clamping block 408. After the cylinder 3031 rotates with the spray pipe 302, the first clamping block 406 and the second clamping block 408 are clamped and move synchronously. After the spray member 303 is in a horizontal state when it rotates, the second clamping block 408 is clamped with the first clamping block 406, that is, in the process of water flow driving the nozzle 3032 to rotate, it can also drive the second clamping block 408 to rotate synchronously with the first clamping block 406, so that the exhaust fan 4 works synchronously with the nozzle 3032.

[0080] Furthermore, the top of the smoke processor 402 is connected to a U-shaped discharge pipe 401, the end of which extends into the water injection pool. The treated air enters the water injection pool, which can accelerate the flow of water in the water injection pool, facilitate the heat dissipation of the water and extinguish the fire of the vehicle.

[0081] The use process of the electric vehicle fire extinguishing application provided by the present invention is as follows:

[0082] In normal use, the movable short baffle 102 is located in the parking surface and remains horizontal with the parking surface, so as not to affect the normal entry and exit of vehicles.

[0083] When the electric vehicle catches fire, the control system 2 can automatically control the short baffle 102 to connect and close with the ends of the two long baffles 101. Specifically, the fire sensor device detects a fire signal, and the single chip microcomputer first controls the driving member to work, and the driving member drives the baffle of the short baffle 102 to rotate until it closes with the ends of the two long baffles 101 to form a water injection pool (such as Figure 4As shown in ), during the closing process, the linkage assembly 304 drives the sprinkler pipe 302 to rotate from a vertical state to a horizontal state, and then the single chip microcomputer controls the solenoid valve to open to inject water into the water injection pool. During the water circulation in the sprinkler pipe 302, the turbine 3036 is driven to rotate by the water flow, and then the rotating shaft 3035 and the spray disc 3033 are driven to rotate synchronously, so that the water is sprayed out from the through hole 3034 over a wider range, and the fire extinguishing effect on the electric vehicle is better. At the same time, in the process of driving the sprinkler head 3032 to rotate, the second clamping block 408 and the first clamping block 406 can also be driven to rotate synchronously, so that the exhaust fan 4 works synchronously with the sprinkler head 3032 to absorb and process the smoke and reduce the amount of smoke diffusion. The treated air enters the water injection pool, which can accelerate the flow of water in the water injection pool, facilitate the heat dissipation of the water and the fire extinguishing of the vehicle.
