Description

Technical Field

[0001] This utility model relates to the field of vehicle fire extinguishing technology, and in particular to a vehicle isolation and cooling fire extinguishing device. Background Technology

[0002] With the increasing popularity of new energy vehicles, the number of new energy vehicles on the road is growing, and their safety issues are becoming increasingly prominent. Compared with traditional vehicles, fires in new energy vehicles are mainly caused by battery fires. Fires involving the battery in the vehicle chassis generally occur in the following stages: Phase 1: 80℃~120℃: Within this temperature range, the solid electrolyte membrane (SEI) in the battery begins to decompose; Second stage: 150℃~270℃: The diaphragm closes, shrinks and decomposes, the positive and negative electrodes are short-circuited, and the negative electrode reacts with the carbonate solvent in the electrolyte to generate lithium carbonate, ethylene, ethane and propane, etc., releasing a large amount of heat, and the temperature of the lithium-ion battery continues to rise. The third stage: 170℃~450℃, the safety valve opens and gas is ejected. At high temperatures, many reactions occur in the battery, producing various gases. The internal pressure of the battery continues to increase, and the ejected gas ignites and explodes. The ejected gas contains a large amount of flammable gas. When it encounters air, and the temperature reaches the ignition point or there is an ignition source, the conditions for combustion are met, and it will ignite and release a large amount of heat. The temperature can reach as high as 900℃.

[0003] Existing fire extinguishing technologies and equipment generally cool down the vehicle during the first or second stage of fire suppression, typically by spraying the entire vehicle with fire hydrants or extinguishers. This method cannot effectively cool the battery in the vehicle's chassis, resulting in low extinguishing efficiency. To address this issue, Chinese patent document CN219941638U discloses a fire emergency component for vehicles. This component consists of a first spray device selectively movable to the bottom of the vehicle, and a second spray device selectively movable to form an isolation chamber with the first spray device to contain the vehicle. The first and second spray devices then work together to spray water for cooling. The advantage of this solution is that it allows for targeted cooling of the battery in the chassis using the first spray device, while the second spray device provides isolation to prevent the fire from spreading. However, its disadvantages include the limitation that it can only operate at the location of the vehicle fire, and the fact that both the first and second spray devices are movable independently, leading to incoordination during movement and inconvenience in water supply, resulting in complex operations and a low safety factor. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an automotive isolation and cooling fire extinguishing device. By adopting a fully enclosed structure, it can effectively isolate vehicles or other property on both sides of the burning vehicle. By improving the automation level of the fire extinguishing device, it can improve the safety of operators and more effectively control and isolate the fire.

[0005] To achieve this objective, the present invention adopts the following technical solution: This utility model provides a vehicle isolation and cooling fire extinguishing device, including a mobile control frame and a fire extinguishing enclosure disposed on the side of the mobile control frame near the fire vehicle. The bottom of the mobile control frame is also provided with a water inlet pipe that cooperates with the fire extinguishing enclosure and a lifting and translating mechanism for moving the vehicle. The fire extinguishing enclosure includes a chassis spray frame and several body spray frames arranged along the length of the chassis spray frame. The several body spray frames and the chassis spray frame form a fire extinguishing chamber that cooperates with the vehicle body. The fire extinguishing enclosure is located within the fire extinguishing chamber. The fire chamber is also equipped with end face water spray racks at both ends; the water inlet pipe is also fixed with water distribution pipes at both ends, one end of the water distribution pipe is connected to the water inlet pipe, and the other end is connected to the end face water spray rack near the vehicle body entry end. The bottom of several body water spray racks is connected to the water distribution pipe. The chassis water spray rack and the end face water spray rack near the mobile control frame are connected to the water inlet pipe. Insertion channels that cooperate with the vehicle body wheels are provided between the two sides of the chassis water spray rack and the two water distribution pipes. When extinguishing a fire, the chassis water spray rack is inserted under the chassis between the wheels.

[0006] The beneficial effects of this utility model are as follows: The fire extinguishing equipment in this case can completely surround the burning vehicle and spray water to cool it down, or even extinguish the fire, or buy time for professional firefighters to carry out rescue operations and protect property and people's safety. The lifting and translating mechanism at the bottom of the fire extinguishing equipment can also lift the burning vehicle so that the tires are off the ground, and transport the burning car to a designated location for fire extinguishing.

Detailed Implementation

[0009] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0010] To address the problems of existing fire extinguishing technologies and equipment failing to effectively spray water onto the battery in the car chassis, or being uncoordinated during movement, resulting in complex operations and low safety for operators, this utility model provides a car isolation and cooling fire extinguishing device.

[0011] Example 1: Specifically, it includes a mobile control frame 1 and a fire extinguishing enclosure 2 installed on the side of the mobile control frame 1 near the burning vehicle. The bottom of the mobile control frame 1 is also equipped with a water inlet pipe 11 that works in conjunction with the fire extinguishing enclosure 2. The mobile control frame 1 also has a functional box for storing other fire extinguishing equipment and control units for the fire extinguishing enclosure 2 to perform fire extinguishing operations. In use, the mobile control frame 1 moves the fire extinguishing enclosure 2 to the burning vehicle, and then the water inlet pipe 11 connects to fire hydrants and other facilities to supply water to the fire extinguishing enclosure 2 to cool and extinguish the fire. The fire extinguishing enclosure 2 in this example is a structure that completely surrounds the burning vehicle and precisely extinguishes and cools the vehicle chassis. It can effectively isolate vehicles or other property on both sides of the burning vehicle, as well as isolate the top of the vehicle, preventing the spread of flames. The structure of the fire extinguishing enclosure 2 is described in detail below: Fire extinguishing enclosure... The enclosure 2 includes a chassis water spray frame 21 and several enclosure body water spray frames 22 arranged along the length of the chassis water spray frame 21. The several enclosure body water spray frames 22 and the chassis water spray frame 21 form a fire extinguishing chamber 24 that cooperates with the vehicle body. In this way, the chassis water spray frame 21 can accurately cool the battery of the vehicle chassis, and the enclosure body water spray frames 22 can effectively isolate and control the fire from the side and top. Furthermore, the fire extinguishing enclosure 2 is also equipped with end face water spray frames 23 at both ends of the fire extinguishing chamber 24. In addition, in order to ensure the water supply to the entire fire extinguishing enclosure 2, the inlet pipe 11 is also fixed with a water distribution pipe 12 at both ends. One end of the water distribution pipe 12 is connected to the inlet pipe 11, and the other end is connected to the end face water spray frame 23 near the vehicle body entry end. The bottom of the several enclosure body water spray frames 22 is connected to the water distribution pipe 12, and the chassis water spray frame 21 and the end face water spray frame 23 near the mobile control frame 1 are connected to the inlet pipe 11. Specifically: (1) The chassis water spray frame 21 includes three chassis water spray pipes 211. The three chassis water spray pipes 211 are connected to the water inlet pipe 11 at one end near the mobile control frame 1, and the other ends are connected to each other. Preferably, the chassis water spray frame 21 is provided with insertion channels 13 that cooperate with the vehicle wheels between the two sides and the two branch water pipes 12. When extinguishing the fire, the chassis water spray frame 21 is inserted under the chassis between the wheels, which makes it convenient to put the burning vehicle into the fire extinguishing chamber 24. (2) The body spray frame 22 includes a side spray pipe 221 and a top spray pipe 222. The bottom of the side spray pipe 221 is connected to the water distribution pipe 12, and the top of the side spray pipe 221 is connected to the top spray pipe 222 through an angled pipe. (3) The end face spray frame 23 includes an inverted U-shaped end face spray pipe 231. The bottom of the end face spray pipe 231 near the moving control frame 1 is connected to the water inlet pipe 11, and the end face spray pipe 231 near the vehicle body entry end is connected to the water distribution pipe 12. To ensure more even water spraying, water nozzles 25 are evenly arranged on the chassis water spray pipe 211, side water spray pipe 221, top water spray pipe 222, end face water spray pipe 231, and horizontal pipe 2311, all facing the fire vehicle. Preferably, the end face water spray pipe 231 near the mobile control frame 1 has several interconnected horizontal pipes 2311 arranged from top to bottom. The end face water spray frame 23 near the vehicle body entry end is also equipped with a sealing mechanism 232. In this way, when spraying water for cooling, the end face water spray pipe 231 near the mobile control frame 1 and the horizontal pipes 2311 work together to form a water spray grid, which can effectively protect and isolate the mobile control frame 1. The frame 1 and the functional box on it are equipped with a sealing mechanism 232 on the end face water spray frame 23 near the vehicle body entry end. After the burning vehicle enters the fire extinguishing chamber 24, the fire extinguishing chamber 24 can be sealed by the sealing mechanism 232. In the attached figure, only the fixed frame of the sealing mechanism 232 is shown. The fixed frame can be made of high temperature resistant material into a curtain-like structure that automatically lifts and lowers via sliding rails or other similar methods. It will not be described in detail here. In this way, the burning vehicle is completely placed in the fully enclosed fire extinguishing chamber 24 when it is being extinguished and cooled, which makes the fire extinguishing and cooling effect of the burning vehicle better and the fire isolation effect better.

[0012] The above mainly refers to the fire extinguishing enclosure 2 constructed by the chassis water spray frame 21, the body water spray frame 22, and the end face water spray frame 23. The fire extinguishing enclosure 2 forms an independent fire extinguishing chamber 24 that works with the burning vehicle. It mainly uses water spray heads 25 to form a spray for fire extinguishing, cooling, and isolating the fire. In this case, in order to further improve the sealing of the fire extinguishing chamber 24, the outer surface of the fire extinguishing enclosure 2 is also covered with a fireproof cloth 27, specifically for the body water spray frame 22 and the end face water spray frame 23 near the vehicle body entrance.

[0013] After the fire extinguishing enclosure 2 is constructed, in order to enable the entire fire extinguishing equipment to move flexibly and respond promptly in the event of a fire, the two ends of the mobile control frame 1 and the ends of the two water distribution pipes 12 away from the water inlet pipe 11 are equipped with main moving wheels 14 that cooperate with each other; one set of two main moving wheels 14 arranged diagonally are also equipped with cooperating drive motors, and the end of the chassis spray frame 21 away from the water inlet pipe 11 is equipped with auxiliary moving wheels 15. Both the main moving wheels 14 and the auxiliary moving wheels 15 are omnidirectional wheels. The main moving wheels 14 are driven by the diagonally arranged drive motors, which enable the entire equipment to move. At the same time, by adjusting the direction of the main moving wheels 14, the entire fire extinguishing equipment can move at various angles such as horizontal, vertical and diagonal. This is a common technical means that can be easily achieved. In order to ensure the structural strength during movement and prevent the fire extinguishing enclosure 2 from deforming, several reinforcing ribs 26 are also provided along the circumference at both ends of the fire extinguishing enclosure 2.

[0014] Example 2: In Example 1, the main approach was to construct an independent space matching the burning vehicle to extinguish the fire, cool it down, and isolate the spread of the fire. However, when the fire is large and difficult to control, it can still damage surrounding vehicles or other property in a short time. Therefore, we need a mechanism that can use fire extinguishing equipment to cool down and extinguish the fire while simultaneously moving the burning vehicle to a relatively open and safe area to ensure the safety of people and property. Thus, the bottom of the mobile control frame 1 is also equipped with a lifting and translating mechanism 3 that moves the vehicle. The lifting and translating mechanism 3 includes a lifting motor 31 and a lifting platform 32. The lifting platform 32 includes a lifting platform 321 and two sets of mobile frames 322 respectively located between two adjacent chassis water spray pipes 211, as shown in the figure. These frames are mainly located between the two chassis water spray pipes 211 to facilitate the lifting platform. The movement of the 322 does not interfere with the fire extinguishing enclosure 2. The moving frame 322 is equipped with several sets of translation wheels 3221 along the length of the fire extinguishing enclosure 2. The main lifting rod 323 and the auxiliary lifting rod 324 are set between the two sides of the moving frame 322 and the lifting platform 321. The lifting motor 31 drives the lifting platform 321 to rise and fall through the main lifting rod 323 and the auxiliary lifting rod 324. In this way, when moving a burning vehicle, the lifting motor 31 can use the main lifting rod 323 and the auxiliary lifting rod 324 to drive the lifting platform 321 to rise towards the vehicle chassis and then lift the vehicle. In order not to reduce the cooling effect of water spraying, the lifting platform 321 can be hollowed out (not shown in the figure). In this way, when the fire extinguishing equipment is moved by the main moving wheels 14, it can also move the burning vehicle. The following is a detailed description of the lifting method: (1) Based on the structural design of the elevator 32, the main lifting rod 323 and the auxiliary lifting rod 324 are arranged in a cross manner, and the main lifting rod 323 and the auxiliary lifting rod 324 are hinged in the middle; the movable frame 322 is provided with a sliding groove 3222 that cooperates with the main lifting rod 323 along the length direction of the fire extinguishing enclosure 2; one end of the main lifting rod 323 is hinged to the bottom of the lifting platform 321, and the other end is slidably connected to the sliding groove 3222; one end of the auxiliary lifting rod 324 is slidably connected to the bottom of the lifting platform 321, and the other end is slidably connected to the movable frame 3222. 2. Hinged connection; Thus, when the connection point between the main lifting rod 323 and the slide 3222 moves closer to the hinge point between the auxiliary lifting rod 324 and the moving frame 322, the lifting platform 321 can lift the burning vehicle. When the connection point between the main lifting rod 323 and the slide 3222 moves away from the hinge point between the auxiliary lifting rod 324 and the moving frame 322, the lifting platform 321 lowers its height, thereby lowering the burning vehicle. A horizontal plate 325 and a moving plate 326 are thus provided between two adjacent moving frames 322. The two ends of the horizontal plate 325... The moving plate 326 is fixedly connected to two movable frames 322 respectively. Both ends of the moving plate 326 are fixedly connected to the main lifting rod 323 on the opposite side of each of the two movable frames 322. It also includes a lifting shaft 327 that cooperates with the horizontal plate 325 and the moving plate 326. The axis of the lifting shaft 327 is the same as the length direction of the fire extinguishing enclosure 2. One end of the lifting shaft 327 is fixedly connected to the horizontal plate 325, and the other end passes through the moving plate 326. The lifting shaft 327 is threadedly connected to the moving plate 326, thus allowing the fire extinguishing enclosure 2 to be lifted by rotating the lifting shaft 327. The movable plate 326 moves closer to or further away from the horizontal plate 325. Since the two ends of the horizontal plate 325 and the movable frame 322 are fixed, their relative positions remain unchanged. The main lifting rods 323 on the opposite side of the two movable frames 322 are fixed at both ends of the movable plate 326. When the movable plate 326 moves closer to or further away from the horizontal plate 325, the connection point between the main lifting rod 323 and the slide 3222 and the hinge point between the auxiliary lifting rod 324 and the movable frame 322 can move closer to or further away from each other, thereby realizing the lifting of the lifting platform 321.

[0015] (2) Based on the structure of the aforementioned elevator 32, since the elevator motor 31 is located at the bottom of the mobile control frame 1, and the elevator 32 needs to be matched with the chassis of the burning vehicle, there is a certain distance between the power shaft of the elevator motor 31 and the lifting shaft 327 of the elevator 32. Therefore, a connecting shaft 33 is also provided between the power shaft of the elevator motor 31 and the lifting shaft 327. The two ends of the connecting shaft 33 are respectively connected to the flanges of the power shaft of the elevator motor 31 and the lifting shaft 327. The elevator motor 31 drives the lifting shaft 327 to rotate through the connecting shaft 33 to control the lifting and lowering of the elevator platform 321; It is important to note that, unlike typical usage environments, in this case, the connecting shaft 33 extends directly under the burning chassis during use, thus facing the high temperature of the burning vehicle. At this time, the water mist sprayed from the other nozzles 25 cannot effectively dissipate heat from the connecting shaft 33, which will affect the raising and lowering of the burning vehicle and easily cause secondary safety accidents. Therefore, during use, the heat dissipation of the connecting shaft 33 under normal structural strength conditions needs to be considered. Specifically, the connecting shaft 33 includes a coaxially arranged connecting rod 331 and connecting cylinder 332, and the connection between the connecting rod 331 and connecting cylinder 332... A heat insulation cavity 333 is formed. Within the heat insulation cavity 333, several connecting units 334 are evenly arranged along the axial direction of the connecting rod 331 from one end of the connecting shaft 33 to the other. The connecting rod 331 and the connecting cylinder 332 are fixedly connected by the connecting units 334. Each connecting unit 334 includes several connecting blocks 3341 evenly arranged circumferentially along the connecting rod 331. A water inlet structure 335 is provided at the end of the connecting shaft 33 near the water inlet pipe 11, and a water spray head 25 is also provided at the end of the connecting shaft 33 near the lifting platform 321. Thus, water can enter the heat insulation cavity 333 through the water inlet structure 335 and exit through the connecting... The water inlet structure 335 of shaft 33 flows from one end to the spray nozzle 25 at the other end, which can continuously cool the entire connecting shaft 33 during the entire fire extinguishing process. At the same time, the connecting block 3341 set along the connecting rod 331 can interfere with the flow of cooling water in the heat insulation cavity 333, making the flow more uniform (especially when the connecting shaft 33 rotates), and will not cause a significant temperature difference between the upper and lower parts of the heat insulation cavity 333 (the burning vehicle mainly heats the upper surface of the connecting shaft 33, rather than the surface closer to the ground), thus achieving a better heat dissipation effect.

[0016] In the above scheme, since the lifting motor 31 drives the lifting shaft 327 to rotate via the connecting shaft 33, water is injected into the heat insulation cavity 333 of the rotating connecting shaft 33 using the water inlet structure 335. Specifically, the water inlet structure 335 includes a water inlet sleeve 3351, with both ends of the water inlet sleeve 3351 rotatably connected to the connecting shaft 33. A water inlet cavity 3352 is formed between the water inlet sleeve 3351 and the connecting shaft 33, and the water inlet cavity 3352 is connected to the heat insulation cavity 333. For example, a connection hole can be opened in the wall of the water inlet sleeve 3351 where the water inlet cavity 3352 and the heat insulation cavity 333 are connected. 3351 is also provided with a water inlet 3353, which is connected to the water inlet pipe 11 or the chassis spray pipe 211. In this way, the water inlet sleeve 3351 and the connecting shaft 33 rotate relative to each other. That is, when the connecting shaft 33 rotates, it will not drive the water inlet sleeve 3351 to rotate synchronously. This allows the water inlet sleeve 3351 to remain relatively stationary. Thus, the water inlet 3353 can be connected to the water inlet pipe 11 or the chassis spray pipe 211 using a metal hose, so that the water flow can effectively enter the heat insulation cavity 333 through the water inlet structure 335 and finally be sprayed out from the spray head 25 near the end of the elevator 32.

[0017] (3) In order to deal with different situations when vehicles catch fire, the elevator 32 may need to be lifted at different positions on the vehicle chassis. Therefore, the elevator 32 needs to have a certain ability to be adjusted along the length of the fire extinguishing enclosure 2. Thus, the bottom of the moving control frame 1 is also fixed with a translation seat 34 that cooperates with the lifting motor 31. The middle of the translation seat 34 is provided with a translation groove 341 that cooperates with the lifting motor 31. The translation seat 34 is also provided with a translation drive mechanism that drives the lifting motor 31 to move along the length of the fire extinguishing enclosure 2. The translation drive mechanism can adopt a structure similar to that of a motor drive. Here, the structure in the attached figure is used as an example for description. That is, the translation drive mechanism includes a screw mechanism set on both sides of the translation groove 341 and a slide that cooperates with the tail of the lifting motor 31. The two ends of the slide are threadedly connected to two sets of screw mechanisms respectively. In this way, when the motor drives the screw to rotate, the lifting motor 31 can slide along the translation groove 341 to adjust its position.

[0018] In summary, after a car fire is detected, the operator remotely activates the fire extinguishing equipment, enters the parking space number, and the equipment automatically moves to the front of the designated parking space. The operator then connects the water source to the equipment. While the equipment is spraying water, another command is issued, and the equipment automatically moves to the location of the burning vehicle. The chassis spray frame 21 extends into the car chassis and continuously sprays water. The left and right sides are isolated from adjacent vehicles by the body spray frame 22, which simultaneously sprays water on both sides of the burning vehicle. The top spray pipe 222 also provides protection for the parking lot's roof facilities and sprays water on the top of the car. The end spray pipe 231 near the mobile control frame 1 isolates and protects the fire extinguishing equipment control section, while also spraying water to cool the front of the burning vehicle.

[0019] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
