Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle fire extinguishing technology, in particular to a car insulation and cooling fire extinguishing equipment and control system. BACKGROUND

[0002] With the popularity of new energy vehicles, the number of new energy vehicles in society is increasing, and the safety problem is increasingly prominent. Compared with traditional cars, the main cause of fire in new energy vehicles is battery fire. The battery on the car chassis generally goes through the following stages: First stage: 80℃-120℃: In this temperature range, the solid electrolyte film (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, the negative electrode and the carbonate solvent in the electrolyte have a side reaction to generate lithium carbonate, ethylene, ethane and propane, etc., and release a large amount of heat, and the temperature of the lithium ion battery continues to rise; Third stage: 170℃-450℃, the safety valve opens and gas is ejected, many reactions occur in the battery at high temperature, producing various gases, the internal pressure of the battery continues to increase, and the process of ignition and explosion of the ejected gas, the ejected gas contains a large amount of flammable gas, when it meets air, the temperature reaches the ignition point or there is an ignition source, the conditions for combustion are met, it will ignite and release a large amount of heat, the temperature can be as high as 900℃.

[0003] The existing fire extinguishing technology and equipment generally start to cool and extinguish at the first stage or the second stage. Generally, a fire hydrant or a fire extinguisher is used to spray the whole car. This fire extinguishing method cannot effectively spray water to cool the battery on the car chassis, resulting in low fire extinguishing efficiency. To solve this problem, a fire emergency assembly for a vehicle is disclosed in Chinese patent document No. CN219941638U, which is movable to the bottom of the vehicle by the first spraying device, and the second spraying device is movable to form an isolation cavity containing the vehicle with the first spraying device, and then the first spraying device and the second spraying device spray water to cool down. The advantage of this scheme is that the first spraying device can be used to cool the battery in the chassis flexibly, and the second spraying device can be used to isolate and prevent the spread of fire. However, its defects are that it can only work at the place where the vehicle fire occurs, and the first spraying device and the second spraying device are moved separately, which is not coordinated during movement, and it is not convenient to supply water, resulting in complex operation for the operator and low safety factor. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose an automotive isolation cooling fire extinguishing device and control system. 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 invention provides a vehicle isolation and cooling fire extinguishing device, comprising a mobile control frame and a fire extinguishing enclosure disposed on the side of the mobile control frame near the fire-affected vehicle. The bottom of the mobile control frame is further 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 a plurality of body spray frames arranged along the length of the chassis spray frame. The plurality of body spray frames and the chassis spray frame form a fire extinguishing chamber that cooperates with the vehicle body. The fire extinguishing enclosure is used for fire extinguishing... The 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; the chassis water spray rack has insertion channels that cooperate with the vehicle body wheels between its two sides and the two water distribution pipes; when extinguishing a fire, the chassis water spray rack is inserted under the chassis between the wheels.

[0006] A vehicle isolation, cooling, and fire extinguishing control system for controlling the vehicle isolation, cooling, and fire extinguishing equipment as described above, comprising the following modules: The main control module, as the control core, is used to receive external commands and control other sub-modules; The operation module is used to control the water spray status and vehicle lifting; The drive module drives the fire extinguishing equipment to move forward or backward, and to move left or right; The communication and control module is responsible for communicating between the fire extinguishing equipment and the host computer, as well as with the wireless remote control, and for issuing instructions to the central control module within the preset operating range of the fire extinguishing equipment.

Detailed Implementation

[0010] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0011] To address the problems of existing fire extinguishing technologies and equipment failing to effectively spray water onto the battery in the vehicle chassis, or being uncoordinated during movement, resulting in complex operations and low safety for operators, this invention provides a vehicle isolation and cooling fire extinguishing device.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] (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.

[0017] 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.

[0018] (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.

[0019] Example 3: Also includes a vehicle isolation cooling and fire extinguishing control system for controlling the vehicle isolation cooling and fire extinguishing equipment as described in Examples 1 and 2, comprising the following modules: The main control module, as the control core, is used to receive external commands and control other sub-modules; The operation module is used to control the water spray status and vehicle lifting. Specifically, 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. Then, while the equipment is spraying water, another command is issued, and the equipment automatically moves to the location of the burning vehicle. The chassis water 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 water spray frame 22. At the same time, the body water spray frame 22 sprays water on both sides of the burning vehicle. The top water spray pipe 222 can also form a protection for the parking lot roof facilities, and at the same time, the top water spray pipe 222 sprays water on the top of the car. The end face water spray pipe 231 near the mobile control frame 1 isolates and protects the fire extinguishing equipment control part, and at the same time, the end face water spray pipe 231 near the mobile control frame 1 sprays water to cool down the front of the burning vehicle. The drive module drives the fire extinguishing equipment to move forward or backward, and to move left or right; The communication and control module is responsible for communicating between the fire extinguishing equipment and the host computer, as well as with the wireless remote control, and for issuing instructions to the central control module within the preset operating range of the fire extinguishing equipment. The laser navigation module constructs a 3D point cloud map of the surrounding environment and uses a laser controller to process the acquired contour information to obtain navigation position and attitude information for adjusting the driving state. LiDAR emits laser beams and then receives the reflected beams to sense the surrounding environment and calculate distances, thus obtaining a 3D point cloud map of the surrounding environment. After the map is built, its laser controller processes the acquired contour information and obtains the position and attitude information during navigation. It then uses this information to control the direction, speed, and attitude of the navigation fire extinguishing equipment, and automatically guides its movement using path planning algorithms. The safety module includes obstacle avoidance laser sensors and edge sensors, operation warning lights, and emergency stop switches to prevent collisions with other equipment and operators and to provide warnings. By using lasers to measure parameters such as the distance or displacement of the object being measured, combined with setting trigger conditions, implementing anti-collision protection, and monitoring and maintenance steps, anti-collision protection for equipment and operators is achieved; the operation indicator light serves as a warning during the operation of the fire extinguishing equipment, and pressing the emergency stop switch in case of abnormality protects the equipment and operators; The power supply module is used to supply power to the above modules; The central controller can read the battery status and upload it to the host computer in real time via a network communication system to perform battery health management and automatically alarm in case of abnormalities.
