Description

Technical Field

[0001] This invention relates to the field of intelligent fire-fighting equipment technology, specifically to an intelligent unattended rapid fire-fighting and extinguishing equipment for new energy vehicles. Background Technology

[0002] With the increasing popularity of new energy vehicles, their safety issues, especially the risk of lithium battery fires, are becoming increasingly prominent. Lithium batteries are characterized by uncontrollable chemical reactions, rapid fire spread, extremely high temperatures, and the release of large amounts of toxic fumes when they experience thermal runaway. Moreover, the probability of thermal runaway increases significantly with the charging process and the increase in the number of years of use, posing a serious challenge to fire safety. Existing fire extinguishing equipment for new energy vehicles mainly includes the following types: Vehicle-mounted fire extinguishers: The extinguishing agents in vehicle-mounted fire extinguishers are difficult to reach the core of the lithium battery, and cannot stop the continuous chemical reaction of the lithium battery. Moreover, the combustion of lithium batteries does not depend on oxygen, and isolating oxygen still cannot suppress the fire; Firefighting water extinguishing: The response time is long, and firefighters are unlikely to arrive within the golden 3-minute fire extinguishing time. Fire trucks cannot enter scenarios such as underground parking lots, and the water flow is difficult to reach the lithium battery at the bottom of the vehicle. Even with a large amount of water, it is still not enough to stop the fire; Fire blankets: They cannot stop the combustion of lithium batteries on their own and need to be used in conjunction with a large amount of water for cooling. Otherwise, the high temperature flames can penetrate the blanket. Operation is also limited in confined spaces such as underground parking lots, and it depends on the timely response of on-site personnel; Containment dike flooding equipment: It is necessary to achieve complete flooding by covering the fire blanket and filling it with water, but it cannot stop the continuous combustion of lithium batteries. It has poor applicability in confined spaces, a long response time, and safety risks during operation.

[0003] In addition, in enclosed environments such as underground parking lots, where vehicles are densely packed and spaces are confined, traditional equipment struggles to quickly create an effective fire-fighting space, which can easily lead to nearby vehicles being ignited. Moreover, existing equipment suffers from low automation, slow response, and poor spatial adaptability. Therefore, there is an urgent need for a portable device that can adapt to confined spaces, respond quickly, and automatically complete fire-fighting operations. Summary of the Invention

[0004] To address the aforementioned issues such as vehicle-mounted fire extinguishers being unable to reach the core of lithium batteries, slow fire water response and difficulty in entering underground parking lots, fire blankets and flooding equipment relying on manual labor and having poor applicability, difficulty in quickly creating effective fire extinguishing space in confined spaces, insufficient automation and response speed, and easy spread of fire, this invention provides an intelligent unattended rapid fire extinguishing device for new energy vehicles.

[0005] The solution adopted by this invention to solve its technical problem is: an intelligent unattended rapid fire extinguishing device for new energy vehicles, including an autonomous driving cabin, folding side doors, and a rear frame. A water tank is integrated into the autonomous driving cabin, and drive wheels are installed below the cabin. A connecting frame is fixed to the rear of the autonomous driving cabin. The connecting frame and the rear frame are arranged correspondingly front and rear. Symmetrically arranged folding side doors are hinged between the connecting frame and the rear frame. Each folding side door is composed of multiple side door panels that are sequentially hinged together. Casters are installed below the side door panels and the rear frame. Water spray pipes are arranged vertically and vertically on the inner side of the folding side doors and are connected to the water tank. A top roller shutter assembly is installed above the autonomous driving cabin, and a... The fire truck has a rear roller shutter assembly. When the folding side door is unfolded, and the roller shutter doors of the top roller shutter assembly and the rear roller shutter assembly are opened simultaneously, they enclose the rear of the automatic driving cabin to form a rectangular shell structure. An exhaust port is opened on the side of the connecting frame near the folding side door. The interior of the fire truck is connected to the openings on both sides of the connecting frame through the exhaust port to form an exhaust channel. A top spray pipe is installed on the top of the exhaust channel. A sealing door is slidably installed at the exhaust port. The sealing door is a push door and is controlled to open and close by a pulling assembly to achieve the sealing and opening of the exhaust port. A sealing strip is longitudinally slidably fitted on the upper end of the side door panel. The sealing strip is controlled to move up and down by the pulling assembly. After the sealing strip moves up, it supports the top roller shutter door and seals the gap between the folding side door and the top roller shutter door.

[0006] Furthermore, the pulling assembly includes two motors symmetrically installed in the connecting frame. A rotating shaft is fixedly connected to the output end of the two motors. The rotating shaft is longitudinally arranged in the connecting frame and located on the outside of the sealing door. A pull rope is wound on the rotating shaft. A pull ring is fixed on the outside of the sealing door. A groove is opened inside the side door panel. A push plate is connected below the sealing strip and slides longitudinally in the groove. The pull rope passes through the pull ring and moves into the groove of the side door panel, and is supported under the push plate in a concave state. The pull rope passes through the side door panels arranged in sequence and its end is connected to the rear frame.

[0007] Furthermore, the top roller shutter assembly includes a roller shutter box disposed above the autonomous driving cabin. A main shaft is rotatably mounted inside the roller shutter box. A motor is installed on the roller shutter box. The output end of the motor and the end of the main shaft are fixedly fitted with meshing gears. A top roller shutter door is wound around the main shaft. When the top roller shutter door is unfolded, it horizontally surrounds the top of the fire truck. The rear roller shutter assembly adopts a rear roller shutter door, and the rest of the structure is the same as the top roller shutter assembly. When the rear roller shutter door is unfolded, it vertically surrounds the rear side of the fire truck.

[0008] Furthermore, the side panel has through holes on both sides that communicate with the groove. The height of the through holes is higher than the bottom surface of the push plate. When the pull rope is tightened, it pushes the push plate to move upward.

[0009] Furthermore, a drive unit for controlling the folding or unfolding of the folding side door is installed between the connecting frame and the rear frame. The drive unit is located at the top center of the connecting frame and is a multi-stage telescopic hydraulic cylinder.

[0010] Furthermore, the inner sides of the two door panels of the sealing door are embedded with magnets that attract each other, so that the two door panels of the sealing door can automatically close when no force is applied by the magnetic attraction of the magnets.

[0011] Furthermore, the middle part of the water spray pipe installed on the side door panel is made of rigid water pipe, while the water spray pipe at the hinge of adjacent side door panels is made of flexible water pipe.

[0012] Furthermore, the connecting frame has a horizontal guide rail at the edge of the exhaust port, and the rear side of the sealing door is provided with a guide block adapted to the guide rail. The sealing door is directionally slidably fitted into the guide rail by the guide block.

[0013] Furthermore, the rear frame has a door-shaped structure, the rear roller shutter assembly is installed on the top beam of the rear frame, and door slots are longitudinally opened on the two side columns of the rear frame. The rear roller shutter door is guided through the door slots when it is unfolded.

[0014] The beneficial effects of this invention are: The equipment, through the combined use of folding side doors, top roller shutter assembly, and rear roller shutter assembly, can quickly enclose a rectangular shell fire extinguishing space, precisely enclosing the burning vehicle and preventing the flames and high temperatures from spreading to surrounding vehicles; the water spray pipes installed on the upper and lower sides of the inside of the folding side doors can spray fire extinguishing media in a directional manner onto the vehicle, achieving automatic fire extinguishing; The pulling assembly synchronously controls the opening and closing of the sealing door and the raising and lowering of the sealing strip via motor 2 and pull rope. After the sealing strip moves up, it can support the top roller shutter door and seal the gaps to ensure the airtightness of the fire extinguishing space and force the smoke to concentrate at the exhaust port. After the sealing door is opened, the smoke is discharged through the exhaust channel. The top spray pipe at the top of the channel can spray the smoke a second time to cool it down, extinguish sparks, reduce the spread of toxic fumes, and improve the safety of the operation. The folding side door adopts a multi-panel hinged structure and is driven by a multi-stage telescopic hydraulic cylinder. The unfolding and retraction actions are fast and smooth. The equipment is small in size when folded and can be flexibly stored in narrow spaces such as underground parking lots. When unfolded, it is stably supported by the drive wheels and casters, making it suitable for densely trafficked scenarios. The integrated autonomous driving cabin can navigate to the fire scene autonomously through an intelligent system without human intervention; the entire process from thermal runaway detection to equipment deployment and fire suppression can be completed within the golden 3-minute fire suppression time, solving the problems of traditional equipment relying on manual response and slow speed.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-10 This invention provides a technical solution for an intelligent, unattended, rapid fire extinguishing device for new energy vehicles: Example

[0019] according to Figure 1 and Figure 2As shown, the equipment uses an automated driving cabin 2 as its mobile carrier. A water tank 1 is integrated into the automated driving cabin. The water tank 1 provides a medium such as water or a special extinguishing agent for firefighting operations through a built-in water pump and pipeline system. Drive wheels 9 are installed at the bottom of the automated driving cabin, which are responsible for the movement and steering of the equipment. The automated driving cabin achieves autonomous navigation to the fire scene through an automated driving system. A connecting frame 3 is fixedly welded to the rear of the automated driving cabin 2. The connecting frame 3 has a rectangular frame structure and is positioned correspondingly to the rear frame 5. Symmetrically distributed folding side doors 4 are installed between the connecting frame 3 and the rear frame 5 through a hinge structure. Figure 5 As shown, the folding side door 4 is made up of multiple side door panels 401 that are hinged together in sequence. The adjacent side door panels 401 can rotate relative to each other through hinges or pins, ensuring that the folding side door 4 can be flexibly opened or closed. Casters 10 are installed at the bottom of the side door panels 401 and the rear frame 5. The casters 10 are in contact with the ground and can form a stable support structure together with the drive wheels 9 to prevent the equipment from tilting during operation.

[0020] A top roller blind assembly 6 and a rear roller blind assembly 7 are respectively installed above the autonomous driving bay 2 and on the rear frame. The specific structure of the top roller blind assembly 6 is as follows: Figure 4As shown, the system includes a roller shutter box 601 fixed to the top of the automatic driving cabin 2. The roller shutter box 601 is used to house the roller shutter door components. A main shaft 602 is horizontally rotatably installed inside the roller shutter box 601. Both ends of the main shaft 602 are connected to the inner wall of the roller shutter box 601 through bearings. A top roller shutter door 603 is wound around the main shaft. The top roller shutter door 603 is made of fireproof canvas or thin metal plates. One end is wound around the main shaft 602, and the other end is a free end. When the top roller shutter door 603 is unfolded, it can surround the top of the fire truck as the top wall of the fire truck. A motor 604 is fixedly installed on the outer wall of the roller shutter box 601. Gears 605 are fixedly fitted at the output end of the motor 604 and the end of the main shaft 602, and the two gears 605 mesh with each other to realize power transmission. The structure of the rear roller shutter assembly 7 is exactly the same as that of the top roller shutter assembly 6. The rear frame 5 is a door-shaped structure consisting of a top beam and two side columns. The roller shutter box of the rear roller shutter assembly 7 is fixedly installed on the top beam of the rear frame 5. The rear roller shutter door 703 can be extended downward from the top beam. A door groove 15 is longitudinally provided on the inner side of the two side columns. The shape of the door groove 15 is adapted to the edge of the rear roller shutter door 703. When the rear roller shutter door 703 is extended, its two side edges are embedded in the door groove 15 and slide along the groove to ensure the stability of the longitudinal extension trajectory of the rear roller shutter door 703. The extended rear roller shutter door 703 is longitudinally positioned to surround the rear of the fire truck, sealing the rear end of the fire extinguishing space. When motor 604 starts, it drives the main shaft 602 to rotate through gear 605, causing the top roller shutter 603 and the rear roller shutter 703 to be released or retracted from the roller shutter box. After the top roller shutter and the rear roller shutter are fully extended, they are positioned horizontally and vertically to surround the top and rear of the fire truck, sealing the upper and rear of the fire extinguishing space, thus forming a fire extinguishing space inside the fire truck.

[0021] A water spray pipe 8 is fixedly installed on the inside of the folding side door 4 along the vertical direction. The water spray pipe 8 is connected to the water outlet of the water tank 1 through a flexible hose. The section of the water spray pipe 8 located in the middle of the single side door panel 401 is made of rigid water pipe to ensure stable spray pressure. The section of the water spray pipe located at the hinge of the adjacent side door panel 401 is made of flexible water pipe, which can bend with the rotation of the side door panel 401 to avoid pipe breakage when folding or unfolding. Multiple water spray holes are opened on the side wall of the water spray pipe 8. The fire extinguishing medium forms water mist or water flow through the water spray holes and is evenly sprayed into the fire extinguishing space to realize fire extinguishing of new energy vehicles.

[0022] In practical use, this invention provides an intelligent, unattended, rapid fire extinguishing device for new energy vehicles. When a fire breaks out in a car in the garage, the autonomous driving cabin 2 drives to the fire scene via the drive wheels 9 and moves to the front or rear of the burning car. Then, the folding side door 4 unfolds under the action of the drive components, forming a barrier on both sides of the burning car. Then, the motor 604 drives the gear 605 to rotate, causing the main shaft 602 to rotate and release the top roller shutter 603 and the rear roller shutter 703. The top roller shutter 603 unfolds horizontally to close the top, and the rear roller shutter 703 unfolds longitudinally along the door groove 15 of the rear frame 5 to close the rear side, forming a closed fire extinguishing space. Then, the water tank 1 supplies water to the spray pipe 8 through the pipeline. The spray pipe 8 sprays the fire extinguishing medium into the fire extinguishing space to extinguish the fire on the burning vehicle. After the fire is extinguished, the motor 604 reverses and retracts the roller shutter, while the folding side door 4 closes, and the device returns to its original state. Example

[0023] Based on Example 1, the similarities between this example and Example 1 will not be repeated here. The differences are as follows: Figures 6-9 As shown, an exhaust port 301 is provided on the side wall of the connecting frame 3 near the folding side door 4. The exhaust port 301 is a rectangular opening that communicates with the interior space of the fire truck. The interior of the connecting frame 3 is a hollow structure with openings on both side walls, allowing the interior of the fire truck to form a through exhaust channel 302 through the exhaust port 301 and the openings on both sides of the connecting frame 3. Smoke generated during firefighting can be discharged to the outside of the equipment through the exhaust channel 302. A top spray pipe 16 is installed at the top of the exhaust channel 302. The top spray pipe 16 is connected to the water tank 1, and its spray direction is towards the interior of the exhaust channel 302, which can perform secondary spraying on the smoke flowing through it, reduce the smoke temperature and extinguish sparks, and further improve the fire extinguishing effect.

[0024] The sealing door 303 adopts a sliding door structure, consisting of two door panels that are symmetrically slidably installed at the exhaust port 301 to control the closing and opening of the exhaust port 301. A guide rail 304 is horizontally provided on the connecting frame 3 at the upper and lower edges of the exhaust port 301. A guide block adapted to the guide rail 304 is fixed on the rear side of the sealing door 303. The guide block is slidably fitted inside the guide rail 304, allowing the sealing door 303 to slide left and right in the horizontal direction. The opening and closing action of the sealing door 303 is controlled by the pulling assembly.

[0025] A groove is longitudinally provided on the upper surface of the side door panel 401. The sealing strip 402 is slidably fitted into the groove 404 through the push plate 403 and can move up and down along the longitudinal direction of the groove. The sealing strip 402 is made of elastic material and its upper surface has an L-shaped structure. When the sealing strip 402 moves upward, it supports the top roller shutter door 603 on the one hand, preventing the top roller shutter door 603 from sagging due to its own weight; on the other hand, it seals the gap between the folding side door 4 and the top roller shutter door 603, ensuring the airtightness of the fire extinguishing space and forcing the smoke to flow only towards the exhaust port 301. The upward movement of the sealing strip is also controlled by the pulling assembly.

[0026] The traction assembly includes two motors symmetrically installed inside the connecting frame 3. A rotating shaft 13 is longitudinally fixedly connected to the output end of the two motors 11. The rotating shaft 13 is located outside the sealing door 303, and a pull rope 12 is wound around the rotating shaft. The pull rope 12 is made of high-strength steel wire rope or nylon rope. One end of the pull rope is wound around the rotating shaft 13, and the other end is connected to the rear frame 5. A pull ring 14 is fixedly welded to the outer wall of the sealing door 303. A push plate 403 is fixedly connected below the sealing strip 402. The push plate 403 is longitudinally slidably fitted into the groove 404 of the side door panel 401. 2. After being led out from the pivot 13, the rope first passes through the pull ring 14 to change direction, and then moves into the groove 404 of the side door panel 401. It then passes through the side door panels 401 arranged in sequence, and finally the tail end of the rope 12 is fixed to the rear frame 5. The rope 12 is in a concave state in the groove 404 and supported below the push plate 403. In order to ensure that the rope 12 can effectively push the push plate 403 upward when it is tensioned, through holes communicating with the groove 404 are provided on both sides of the side door panel 401. The height of the through holes is higher than the bottom surface of the push plate 403, so that the rope 12 is always in a concave state in the groove. When motor 11 drives shaft 13 to wind up rope 12, the tension of rope 12 increases, the concave part gradually straightens, and pushes push plate 403 upward, thereby driving sealing strip 402 to move upward. At the same time, rope 12 pulls sealing door 303 along guide rail 304 to slide to both sides through pull ring 14, opening exhaust port 301. When motor 11 reverses to release rope 12, sealing strip 402 and push plate 403 fall under their own weight.

[0027] In practical use, this invention provides an intelligent, unattended, rapid fire extinguishing device for new energy vehicles. When the device enters the fire extinguishing state, motor 11 starts and drives shaft 13 to rotate and retract rope 12. The tension of rope 12 gradually increases, and rope 12 gradually straightens from a concave state in the groove 404 of side door panel 401, pushing push plate 403 upward and causing sealing strip 402 to move upward until it is in close contact with top roller shutter door 603, sealing the gap. At the same time, rope 12 pulls sealing door 303 to both sides through pull ring 14 to open exhaust port 301. Most of the smoke in the enclosed space enters exhaust channel 302 through exhaust port 301. At the same time, top spray pipe 16 in exhaust channel 302 sprays medium to extinguish the smoke for secondary fire. After the fire is extinguished, motor 11 reverses to release rope 12, and push plate 403 and sealing strip 402 fall by their own weight.

[0028] To ensure that the sealing door 303 can close automatically when not subjected to the force of the pulling component, magnets 305 that attract each other are embedded on the inner side of the two door panels of the sealing door 303. The magnets 305 are set along the edge of the door panels. When the two door panels are close to each other, the attraction of the magnets 305 causes the door panels to automatically fit together, thereby closing the exhaust port 301. After the pulling component releases the pull rope 12, the sealing door 303 can close automatically without additional power. The attraction force of the magnets 305 can ensure that the sealing door 303 remains closed when not in operation. Example

[0029] Based on Example 1, such as Figure 1 As shown, a drive unit 17 for controlling the folding or unfolding of the folding side door 4 is installed between the connecting frame 3 and the rear frame 5. The drive unit 17 is located at the top center of the connecting frame 3 and is a multi-stage telescopic hydraulic cylinder. The fixed end of the multi-stage telescopic hydraulic cylinder is hinged to the connecting frame 3, and the telescopic end is hinged to the rear frame 5. When the hydraulic cylinder extends, it pushes the rear frame 5 away from the connecting frame 3, and the folding side door 4 unfolds under the action of tension; when the hydraulic cylinder retracts, it pulls the rear frame 5 closer to the connecting frame 3, and the folding side door 4 folds and closes under the action of thrust.

[0030] The multi-stage telescopic hydraulic cylinder has a large output thrust, which can drive the heavy folding side door 4 to move smoothly. It also has a long telescopic stroke, which can meet the unfolding requirements of the folding side door 4. Furthermore, the speed can be adjusted through the hydraulic control system to ensure the safety of the unfolding or folding process. Example

[0031] Based on the above embodiments, this embodiment discloses an intelligent fire protection system. Based on the portable fire safety equipment described in embodiments one to four, it integrates intelligent sensing, automatic control, and linkage response technologies to achieve unattended and rapid response to thermal runaway fires in new energy vehicles. This system is particularly suitable for scenarios such as large parking lots and underground garages, and can complete the entire process from detection to extinguishing within the golden 3-minute fire extinguishing time.

[0032] This intelligent fire protection system includes the following core components: The intelligent early warning module is responsible for 24-hour real-time monitoring of the thermal runaway status of new energy vehicles in the parking lot, providing an initial trigger signal for the system. Specifically, it includes distributed temperature and smoke sensors covering all parking spaces and passageways; parking space-level temperature and smoke sensors embedded in the parking space floor or ceiling; and a positioning module to pinpoint the exact location of the thermally runaway vehicle. Signal processing module: Responsible for information analysis, command generation and transmission, realizing fully automated control. After receiving the signal from the intelligent early warning system, the signal processing module determines the location and fire level of the thermal runaway vehicle within 10 seconds, and automatically matches the nearest execution system, namely the portable fire safety equipment in Examples 1 to 4, generates commands including navigation path and fire extinguishing mode, and simultaneously sends alarm signals to the auxiliary system; Execution module: Based on the portable new energy vehicle fire safety equipment of Examples 1 to 4, it serves as the execution terminal of the system and is responsible for on-site fire extinguishing operations; Auxiliary modules: These enhance the system's safety and controllability. They mainly include: audible and visual alarm devices deployed at parking lot entrances and exits; and a duty terminal with a display screen and emergency buttons, showing the fire location and equipment status in real time.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
