Abstract
Description
Technical Field
[0001] The present invention relates to the field of power battery safety technology, and in particular to a new energy vehicle power battery fire extinguishing system. Background Art
[0002] With the increasing global attention to environmental protection and sustainable development, new energy vehicles have been widely promoted and applied as a clean energy means of transportation. Compared with traditional fuel vehicles, new energy vehicles have the advantages of low carbon emissions, zero tail gas pollution and energy saving, so they are favored by consumers. However, with the increase in the number of new energy vehicles, new safety hazards have also been brought, one of which is the occurrence of fire accidents. At present, there are no better fire extinguishing measures for fires in power batteries of new energy vehicles. Traditional fire extinguishing agents such as dry powder, carbon dioxide, heptafluoropropane, etc., although they can extinguish battery fires, have poor cooling effects. High-temperature batteries still heat adjacent batteries, which can easily cause thermal runaway of adjacent batteries, and eventually cause thermal runaway to propagate within the module.
[0003] At present, water is the main method for fire fighting of new energy vehicles. However, since the battery compartment is at the bottom of the vehicle, it is difficult for water to enter the battery compartment and directly act on the battery, and the efficiency of water utilization is relatively low. Therefore, after a new energy vehicle catches fire, a large amount of water is needed to extinguish it. It may take 24 hours to completely extinguish a battery fire. The fire fighting time is long and it is very easy to reignite. In addition, the smoke produced by a new energy vehicle fire contains toxic gases, such as polycyclic aromatic hydrocarbons, benzopyrene, asbestos, formaldehyde, benzene and 1,3-butadiene, as well as many other carcinogens. When these carcinogenic compounds catch fire, they are mixed with the combustion product "smoke" and adhere to the firefighting equipment. For firefighters, it is impossible to avoid being exposed to toxic smoke in every operation. They should be aware that the equipment after the fire is contaminated and needs to be decontaminated as much as possible through washing and disinfection. In addition, the environment and location of new energy vehicle fires are diverse, such as garages, densely populated residential areas, etc., which are difficult for fire trucks to enter to extinguish fires.

[0017] 2. Through the rotation of the spoiler fan, the cleaning liquid is stirred and impacted, which significantly enhances the mixing effect of the cleaning liquid. The spoiler fan not only acts directly on the cleaning liquid, but also stirs the cleaning liquid in the area above the temporary storage cylinder through its rotation, thereby promoting the comprehensive mixing of the cleaning liquid. The design of the left baffle plate and the right baffle plate allows the cleaning liquid to be guided to multiple paths during the flow process, thereby increasing the contact opportunities between the cleaning liquids.

This multi-level mixing method ensures that the cleaning liquid can be evenly mixed at all levels. After the cleaning liquid enters the other side of the branch pipe through the flow holes, it will interact with the spoiler fan again and be stirred by it. This multiple stirring and mixing process further refines the mixing effect of the cleaning liquid, making the mixed cleaning liquid more uniform.
[0018] 3. When the spoiler fan rotates, the relative position of the piston magnet and the magnetic plate will change continuously, thus forming a periodic suction and discharge action and a changing magnetic field oscillation, which can prevent the formation of sediment and liquid stratification in the cleaning solution, and maintain the uniformity and stability of the cleaning solution; at low speeds, the suction and discharge action of the piston magnet promotes the mixing of the cleaning solution; at high speeds, the opening of the guide port is increased to meet the high flow demand, which not only improves the mixing efficiency of the cleaning solution, but also realizes flexible control of the flow rate.

[0028] In this embodiment, this patent is a device that uses multiple groups of modules for rapid assembly. The modules are relatively independent of the carrying platform. In the absence of a fire, the carrying platform can perform its own tasks according to different needs. After a fire occurs, each module can be quickly docked with the platform vehicle, arrive at the scene as soon as possible, and perform firefighting tasks. The modules can also be disassembled and brought to a location that is difficult for the vehicle to reach and then reassembled. The carrying modules are in various forms, such as: hand trucks, drones, forklifts, cranes, etc., which can extinguish the fire or disinfect personnel as soon as possible.
[0029] The firefighter uses an air breathing apparatus and uses the gas cylinder 31 as a power source. The gas cylinder valve 32 is opened, and the high-pressure gas in the gas cylinder 31 is reduced in pressure through the pressure reducer 113; the agent injection switch 12 is turned on, and the low-pressure gas after decompression enters the C liquid tank 23 to inject the internal liquid into the A liquid tank 21 and the B liquid tank 22 for mixing; the liquid supply switch 131 is turned on, and the low-pressure gas after decompression enters the A liquid tank pneumatic valve 132 and the B liquid tank pneumatic valve 133, the valve body is opened, and the liquid in the A liquid tank 21 and the B liquid tank 22 are mixed and enter the pump module 4 through the pump group water inlet 41.
[0030] Turn on the spray switch 14, the pump module 4 starts working, and the mixed liquid enters the foaming device 153; at this time, turn on the low-multiple foam spray gun 51, install the medium-multiple foam cylinder 52, and turn on the low-multiple foam spray gun 51 switch to spray medium-multiple foam for fire extinguishing.
[0031] Turn on the gas supply switch 151, and the gas after decompression enters the foaming device 153, and is stirred and mixed with the mixed liquid to foam. At this time, the low-multiple foam spray gun 51 is used alone, and the low-multiple foam spray gun 51 switch can be turned on to spray low-multiple fire extinguishing; when using the decontamination agent, the decontamination switch 161 should be turned on, and the decontamination spray pipe 611 can be connected to decontaminate the environment; or install a decontamination tent 621, and the tent inflation port 622 is connected to the external gas supply switch 151 of the device to inflate the decontamination tent 621, and the decontamination liquid interface 623 is connected to the equipment decontamination quick-release interface 613.

[0033] In particular, the device allows flexible selection and combination of agents according to actual needs. This flexibility enables the equipment to adapt to a variety of complex scenarios and special needs. Whether it is a fire extinguishing operation or a decontamination operation, the agent formula can be adjusted according to the on-site conditions to achieve the best effect; for example, agent A is a foam liquid agent, and agent B is a coolant agent. Foam coolant is obtained by mixing water and agents AB. This mixed agent can more effectively cover the fire source at the power battery of the new energy vehicle during the fire extinguishing process, isolate oxygen, and reduce the temperature of the fire source through cooling, thereby controlling the fire more quickly. Compared with using only foam liquid agents or coolant agents, the foam coolant The comprehensive performance is more superior, which improves the fire extinguishing efficiency and effect; if A disinfectant is a foam agent component, B disinfectant is an active agent component, and C disinfectant is a catalyst agent component, the disinfectant liquid is obtained by mixing ABC agents. The foam agent component helps to evenly distribute and adhere the agent, and the active agent component directly acts on harmful substances such as biological agents and pathogenic microorganisms to kill or inhibit them, while the catalyst agent component may accelerate the reaction process and improve the disinfection efficiency. This mixed disinfectant liquid can not only kill biological agents and pathogenic microorganisms, but also neutralize chemical agents and industrial poisons, providing strong support for emergency rescue and environmental protection.
[0034] The device integrates the functions of fire extinguishing, decontamination and gas supply. It can quickly switch working modes according to different scenarios and needs, support low-multiple foam injection, medium-multiple foam injection and environmental decontamination operations, and improve the applicability and flexibility of the equipment; after the high-pressure gas is reduced by the pressure reducer 113, the pneumatic valve is used to control the mixing and injection of the liquid medicine, ensuring the efficient delivery and precise application of the fire extinguishing agent. Whether it is low-multiple or medium-multiple foam, it can quickly cover the fire source and effectively suppress the spread of the fire; it provides a variety of decontamination methods, including fan-shaped decontamination, atomization decontamination, foam decontamination, etc., which can flexibly respond to different pollution scenarios. The design of the decontamination tent 621 further enhances the convenience and effectiveness of the decontamination operation of fire-fighting equipment, which is particularly suitable for decontamination operations in large-scale or complex environments.
[0035] Example 2, refer to Figure 5-Figure 8 The flow guide mixing component includes a left baffle plate 7, a right baffle plate 71, a temporary storage tube 73 and a spoiler fan 9. A rotating shaft 91 is arranged at the center of the spoiler fan 9. The left baffle plate 7 is located on the left side of the branch tube of the tee pipe 8, and the right baffle plate 71 is located on the right side of the branch tube of the tee pipe 8. The left baffle plate 7 and the right baffle plate 71 are both fixedly connected to the inner wall of the tee pipe 8. The rotating shaft 91 is rotatably connected to the inner cavity of the spoiler fan 9. The temporary storage tube 73 is located at the connection between the straight tube of the tee pipe 8 and the branch tube. The temporary storage tube 73 is fixedly connected to the inner wall of the straight tube of the tee pipe 8. The cleaning liquid can be effectively guided by the arrangement of the left baffle plate 7 and the right baffle plate 71.
[0036] It should be noted that the temporary storage tube 73 is arranged in a trumpet shape as a buffer zone for the flow of the cleaning liquid. The rotating shaft 91 is perpendicular to the plane where the three-way pipe 8 is located. The left baffle plate 7 and the right baffle plate 71 are centrally symmetrically distributed along the central axis of the rotating shaft 91. Through this arrangement, it can be ensured that the cleaning liquid after being drained by the left baffle plate 7 and the right baffle plate 71 can effectively drive the spoiler fan 9 to rotate, and then the cleaning liquid on the temporary storage tube 73 can be stirred. The side walls of the left baffle plate 7 and the right baffle plate 71 are provided with a plurality of flow holes 72. The cleaning liquid after being drained by the baffle plate will enter the other side of the branch pipe of the three-way pipe 8 through the flow holes 72. The spoiler fan 9 There is a gap between the end and the left baffle plate 7 and the right baffle plate 71 to avoid conflict between the spoiler fan 9 and the baffle plate. A guide port 74 is provided on the lower side wall of the temporary storage tube 73 to discharge the cleaning liquid in time. There is a gap between the end face of the left baffle plate 7 close to the spoiler fan 9 and the side wall of the three-way pipe 8, and the end face of the left baffle plate 7 away from the spoiler fan 9 is in contact with the side wall of the three-way pipe 8. Through such an arrangement, it can be ensured that the cleaning liquid will be pushed to the area between the left baffle plate 7, the right baffle plate 71 and the inner wall of the three-way pipe 8 after passing through the spoiler fan 9, and then can be mixed with the cleaning liquid that has not contacted the spoiler fan 9 through the flow hole 72.
[0037] In this embodiment, the cleaning liquid first enters the three-way pipe 8, which is the starting point of the entire mixing process. The left baffle plate 7 and the right baffle plate 71 are respectively located on the left and right sides of the branch pipe of the three-way pipe 8. They preliminarily guide the cleaning liquid to make the cleaning liquid flow along a predetermined path. The cleaning liquid will directly impact the spoiler fan 9. This impact force drives the spoiler fan 9 to rotate. The rotation of the spoiler fan 9 not only enhances the mixing effect of the cleaning liquid, but also stirs the cleaning liquid in the area above the temporary storage tube 73, which helps to evenly distribute the cleaning liquid.
[0038] After passing through the spoiler fan 9, a portion of the cleaning liquid is pushed to the area between the left baffle plate 7, the right baffle plate 71 and the inner wall of the three-way pipe 8, and then enters the other side of the branch pipe of the three-way pipe 8 through the flow hole 72 on the baffle plate. On this side, the cleaning liquid is mixed again with the cleaning liquid that has not directly contacted the spoiler fan 9. This design ensures that the cleaning liquid is mixed at multiple levels, thereby improving the uniformity of the mixing; the cleaning liquid that enters the other side of the branch pipe through the flow hole 72 will interact with the spoiler fan 9 again and be stirred by it. This multiple stirring and mixing process further enhances the uniformity of the cleaning liquid.
[0039] Finally, the uniformly mixed disinfectant is discharged through the guide port 74 at the lower end of the temporary storage tube 73 to continue the subsequent disinfection operation.
[0040] In summary, the flow guide and mixing assembly achieves effective guidance and efficient mixing of the cleaning liquid in the three-way pipe 8 through the clever baffle design, the stirring effect of the spoiler fan 9 and the buffering function of the temporary storage tube 73, thereby improving the effect and efficiency of the cleaning operation.
[0041] Example 3, refer to Figure 8-Figure 11 The magnetic oscillation component includes a magnetic plate 76 and a sleeve 92. The sleeve 92 is fixedly connected to the blades of the spoiler fan 9. The sleeve 92 is hollow. A second spring 93 is fixedly connected to the bottom of the inner cavity of the sleeve 92. A piston magnet 94 is fixedly connected to the end of the second spring 93. The piston magnet 94 is slidably connected to the inner cavity of the sleeve 92. A drainage port 95 matching the piston magnet 94 is provided at the end of the sleeve 92. On the one hand, it can absorb and discharge the disinfectant to promote mixing, and on the other hand, it can ensure that the magnetic force can be effectively transmitted.
[0042] The first spring 75 is used to hold the piston 94 in place and the second spring 76 is used to hold the piston 94 in place.
[0043] In this embodiment, as the spoiler fan 9 rotates, the relative position of the piston magnet 94 and the magnetic plate 76 will continue to change, and the magnetic field between the piston magnet 94 and the magnetic plate 76 will change periodically. When the piston magnet 94 is close to the magnetic plate 76, the magnetic field strength is relatively large; when the piston magnet 94 is far away from the magnetic plate 76, the magnetic field strength is relatively small; the periodic change of the magnetic field strength will produce an oscillation effect in the medicine liquid, and the force caused by the change of the magnetic field will act on the medicine liquid, resulting in periodic flow and oscillation inside the medicine liquid, thereby achieving a mixing effect.
[0044] When the rotation speed of the spoiler fan 9 is slow (indicating that the flow rate of the cleaning liquid required at this time is small), the centrifugal force generated by the rotation of the spoiler fan 9 is small, and the piston magnet 94 is still inside the sleeve 92 under the action of the second spring 93. When the piston magnet 94 is directly opposite to the magnetic plate 76, the magnetic force between the piston magnet 94 and the magnetic plate 76 is also small. Under the action of the magnetic force, the first spring 75 and the second spring 93 will be squeezed and compressed by the magnetic plate 76 and the piston magnet 94 respectively. At this time, the opening of the guide port 74 is small, which limits the flow rate of the cleaning liquid, so that the flow rate of the cleaning liquid is also small at a low rotation speed; and due to the contraction of the piston magnet 94, the sleeve 92 will also pass A portion of the cleaning liquid is sucked in through the drainage port 95, and when the piston magnet 94 is no longer facing the magnetic plate 76, the magnetic force between the two is reduced (gradually less than the elastic force of the spring), so the magnetic plate 76 and the piston magnet 94 will be reset at this time, and the action of the piston magnet 94 first contracting and then resetting can first suck in the cleaning liquid and then spray it out; as the spoiler fan 9 continues to rotate, the piston magnet 94 will periodically face and deviate from the magnetic plate 76, and then will continue to repeat this suction and discharge action. This dynamic flow helps to break the static distribution of molecules or particles in the cleaning liquid, so that they are mixed more evenly. By constantly stirring the cleaning liquid, its uniformity and stability can be maintained; When the rotation speed of the spoiler fan 9 is relatively fast (indicating that a larger flow rate of the disinfectant is required at this time), the centrifugal force generated by the rotation of the spoiler fan 9 is relatively large, and the piston magnet 94 will be located at the end of the sleeve 92 (the drainage port 95) under the action of the second spring 93. When the piston magnet 94 is directly opposite to the magnetic plate 76, the magnetic plate 76 will compress the first spring 75 to a greater extent under the action of the magnetic force, and the opening of the drainage port 74 will also increase accordingly to meet the demand for high-flow spraying.
[0045] This device achieves automatic regulation of the flow rate of the cleaning solution and enhanced mixing effect by cleverly utilizing the interaction between the magnetic field and mechanical movement. The periodic suction and discharge action and the oscillation effect help prevent the formation of sediment and liquid stratification in the cleaning solution, thereby maintaining the uniformity and stability of the cleaning solution. At low speeds, the suction and discharge action of the piston magnet 94 promotes the mixing of the cleaning solution. At high speeds, the opening of the guide port 74 is increased to meet the demand for high flow. This design not only improves the mixing efficiency of the cleaning solution, but also achieves flexible control of the flow rate.
