Description

Technical Field

[0001] This invention relates to the field of special fire-fighting equipment technology, specifically to a mobile fire truck with an deployable fireproof cover and its method of use. Background Technology

[0002] In tunnel fire prevention engineering, effectively blocking the spread of fire and isolating high-temperature smoke are crucial. To accurately control the spread of fire within the tunnel and protect evacuation routes and rescue work areas, fixed fire separation facilities, temporary artificial barriers, or mobile fire barriers are typically used to achieve spatial isolation and protection of the fire zone. However, because tunnels are enclosed and narrow confined spaces, and fires involving new energy vehicles are characterized by rapid fire spread, large smoke production, and high toxicity, rescue equipment needs to be able to move and deploy quickly within limited clearance and lane width. Due to tunnel clearance limitations, complex road conditions, and the need for fire prevention and control in long sections, extremely high demands are placed on the rapid mobility response, dynamic airtight protection, and multi-machine collaborative capabilities of mobile fire prevention equipment.

[0003] Traditional tunnel fire compartmentation methods often rely on fixed facilities or manually erected temporary barriers, resulting in poor flexibility, long deployment times, and difficulty in achieving rapid mobile response to sudden vehicle fires. Even when using mobile fire-fighting equipment with protective structures, they often employ fixed, vertical structures, presenting significant technical shortcomings. First, existing mobile fire barriers typically have their protective panels vertically fixed to the vehicle body, leading to a large vehicle height and significant lateral space occupation. This makes them highly susceptible to scraping against overhead ventilation ducts, lighting fixtures, and sidewall accessories when traveling in the limited clearance and narrow lanes of tunnels, making it difficult to balance rapid and safe maneuverability within the tunnel with large-area protection upon arrival at the scene. Second, tunnel surfaces commonly contain maintenance trenches, differences in cover height, anti-slip structures, and molten fire residue. Traditional rigid deployment mechanisms lack self-adaptive sealing structures, making it easy for the bottom to become suspended after deployment, exposing the surface flames to high-temperature flammable material. Hot and toxic fumes spread from the bottom gaps, and when the fire is extinguished and the equipment is retrieved, the exposed machinery and rollers are easily caught in gravel, ash, and molten residue, causing the mechanisms to jam and become damaged. In addition, when facing long-section fires in long tunnels, the protection width of a single piece of equipment is limited, and traditional mobile fire protection equipment lacks an effective splicing and linkage mechanism. When multiple pieces of equipment are deployed, there are obvious protective gaps, making it impossible to build a continuous and seamless fire and smoke barrier. This not only reduces the overall fire and smoke blocking efficiency, but also poses a serious threat to the safety of evacuated personnel and rescue operations.

[0004] Therefore, the present invention provides a mobile fire-resistant vehicle with an deployable fireproof cover and a method of using the same, in order to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is as follows: Existing mobile fire-fighting equipment suffers from several drawbacks in enclosed and narrow tunnel environments. These include poor mobility due to its vertical structure, susceptibility to scraping tunnel facilities leading to low mobility response, gaps at the bottom after deployment on uneven tunnel surfaces causing leakage of high-temperature smoke and flames, and the risk of mechanical jamming and damage during post-fire recovery due to the entrapment of debris and molten residue. Furthermore, the lack of effective splicing when deploying multiple units in long-distance tunnel fires results in discontinuous fire and smoke barriers. This invention provides a mobile fire-fighting vehicle with a deployable fireproof cover. The design aims to achieve low-profile safe passage within the limited space of a tunnel, adaptive full-enclosure fire and smoke isolation for uneven tunnel surfaces, automatic debris removal and anti-jamming during cover retrieval, and seamless splicing and linkage when multiple vehicles are arrayed. This allows for the rapid construction of an efficient, continuous, and highly mobile tunnel fire isolation barrier, particularly suitable for emergency response needs in fires involving new energy vehicles.

[0006] This invention provides the following technical solution: a mobile fire-fighting vehicle with an expandable fireproof cover, comprising a mobile vehicle body, a control unit, a tilting assembly, a lifting device, an unfolding mechanism, and a fireproof component. The mobile vehicle body is fixedly mounted with a control unit for controlling the entire fire-fighting vehicle. The tilting assembly is fixedly mounted on the mobile vehicle body and is used to switch the lifting device, unfolding assembly, and fireproof component between a horizontal storage state and a vertical working state. The lifting device is fixedly mounted on the tilting assembly and is used to adjust the height of the unfolding mechanism. The lifting device adopts a linear lifting mechanism commonly used in the art, and its fixed end is fixedly mounted on... The movable output end of the flipping component is fixedly connected to the mounting plate of the unfolding component; the lifting device is used to drive the unfolding component and the fireproof component to move vertically as a whole to adjust the height of the fire barrier off the ground and adapt to different tunnel road surface terrains; the unfolding mechanism is fixedly installed on the lifting device, and the unfolding mechanism is used to drive the fireproof component to unfold. The fireproof component is fixedly installed on the unfolding mechanism, and the end of the fireproof cover inside the fireproof component is fixedly connected to the movable part of the unfolding mechanism; when the unfolding mechanism is working, it drives the fireproof component to unfold or retract synchronously laterally through the transmission linkage mechanism to form a continuous fire barrier.

[0007] Preferably, the unfolding mechanism includes a mounting plate, a drive mechanism, a limiting plate, a side plate, driven wheels, driven arms, cross linkages, and synchronous gears. The mounting plate is fixedly mounted on the lifting device. Two sets of drive mechanisms are centrally symmetrically fixedly mounted on the mounting plate. The limiting plate and the side plate are sequentially and symmetrically arranged on both sides of the mounting plate. The driven wheels are centrally symmetrically rotatably mounted on the mounting plate and each engages with the drive mechanism. One end of the driven arm is fixedly mounted on the driven wheel, and the other end of the driven arm is hinged to a cross linkage near the mounting plate. A plurality of cross linkages... The fork links are hinged together at their middle parts to form a scissor structure. The ends of the cross links are respectively fixedly connected to the synchronous gears. The synchronous gears at the ends of adjacent cross links mesh with each other. The cross links are rotatably mounted on the mounting plate, the limiting plate, and the side plate respectively through the rotation shaft of the synchronous gears. The driving mechanism is used to drive the driven wheel to rotate, and then drive several cross links to perform scissor movement through the driven arm. The meshing transmission of the synchronous gears at the ends is used to extend or fold, so as to realize the synchronous and parallel unfolding or retraction of the limiting plate and the side plate relative to the mounting plate.

[0008] Preferably, the driving mechanism includes a drive motor, a reducer, a drive wheel, and a fixed bracket. The reducer is fixedly mounted on the output end of the drive motor, and the drive wheel is fixedly mounted on the output end of the reducer. The drive wheel meshes with the driven wheel, thereby driving the driven wheel to drive the unfolding mechanism on the left and right sides to unfold or retract respectively. The drive motor and the reducer are fixedly mounted on the mounting plate through the fixed bracket.

[0009] Preferably, the fireproof assembly includes an external fireproof cover, a storage drum, a recovery spring, a central shaft, an internal fireproof cover, and a guide opening. The external fireproof cover is fixedly installed on the outside of the storage drum and is used to protect the storage drum. Two parts of the storage drum are symmetrically fixedly installed on the mounting plate. The storage drum has a hollow structure with recovery springs installed at the top and bottom. A central shaft is fixedly installed at the center of the recovery spring. One end of the internal fireproof cover is fixedly installed on the central shaft. The other end of the internal fireproof cover passes through the guide opening on the storage drum and is fixedly connected to its corresponding side plate. The internal fireproof cover is pulled out from the storage drum by the movement of the side plate to form a continuous fire barrier.

[0010] Preferably, the built-in fireproof cover has soft magnets built into its upper and lower ends, so that it can be attracted to the unfolding mechanism after the built-in fireproof cover is unfolded, thus ensuring the stability of the built-in fireproof cover.

[0011] Preferably, a mounting bracket is fixedly installed at the guide opening, and a cleaning brush is fixedly installed on the mounting bracket. A gap for material dropping is provided between the external fireproof cover and the storage roll. When the internal fireproof cover is recycled, the cleaning brush removes the debris inside the internal fireproof cover and it falls through the gap.

[0012] Preferably, a bottom fireproof cover is fixedly installed between the mounting plate, the limiting plate, and the side plate. Fireproof skirts are fixedly installed in an array on the bottom fireproof cover. Counterweight chains are fixedly installed inside each fireproof skirt. This allows the cover to adapt to uneven fireground surfaces, seal the gap between the deployment mechanism and the ground, and cut off the bottom leakage channels for heat radiation and toxic fumes.

[0013] Preferably, the flipping assembly includes a flipping base plate, a flipping bracket, a support plate, a movable plate, and a control cylinder. The flipping base plate is fixedly installed above the mobile vehicle body. The flipping bracket is fixedly installed on the flipping base plate. The support plate is fixedly installed on the flipping bracket. The movable plate is hinged to the support plate. The control cylinder is symmetrically hinged between the movable plate and the lifting base plate.

[0014] Preferably, one side plate is provided with a snap-fit ​​groove for seamless splicing with the fireproof cover of another adjacent mobile fire-fighting vehicle, and the other side plate is provided with a snap-fit ​​block for seamless splicing with the fireproof cover of another adjacent mobile fire-fighting vehicle.

[0015] A method for using a mobile fire truck with an deployable fireproof cover includes the following steps: S1. Autonomous driving and fixed-point positioning: The control unit receives remote control commands and drives the mobile vehicle to the designated location of the burning vehicle in the tunnel; during this driving phase, the tilting components, lifting devices, unfolding mechanisms and fireproof components are kept in a horizontally stacked state to reduce the overall vehicle driving height, adapt to tunnel clearance restrictions and reduce the space occupied in passage. S2. Attitude flipping and height adjustment: After the moving vehicle reaches the predetermined position, the control unit controls the control cylinder in the flipping assembly to push the movable plate to flip upward around the hinge of the support plate, flipping the entire rear device from a horizontal state to a vertical working state; then, the control unit drives the lifting device to adjust the vertical height of the unfolding mechanism according to the tunnel road surface conditions. S3, Linked Deployment and Drum Release: The control unit starts the drive motor, which drives the driven wheel and driven arm in sequence through the reducer and the drive wheel, pushing the cross linkage to perform the scissor extension movement. The synchronous gear meshing causes the limit plate and side plate to unfold outward. At the same time, the built-in fireproof cover is pulled by the side plate, overcoming the torque of the rewinding spring and being continuously pulled out from the guide port of the storage drum. S4. Barrier stability and multi-vehicle splicing: After the built-in fireproof cover is fully deployed, the soft magnets built into its upper and lower ends automatically adhere to the deployment mechanism to maintain stability; the fireproof skirt on the bottom fireproof cover adaptively droops and fits the ground under the action of the counterweight chain; when facing a fire in a long section of tunnel, multiple mobile fire-fighting vehicles are dispatched to park side by side along the longitudinal direction of the tunnel and are seamlessly spliced ​​through the snap-fit ​​grooves and snap-fit ​​blocks on the side plates. S5. Automatic retraction and dust removal reset: After the fire prevention mission is completed, the control unit controls the drive motor to reverse so that the cross linkage folds and retracts. The built-in fireproof cover automatically retracts the storage drum under the winding force of the retracting spring. When passing through the cleaning brush, it brushes off the surface debris and drops it from the gap. Finally, the lifting device lowers, the control cylinder retracts to restore the device to a horizontal state, and the moving vehicle is withdrawn and returned to base according to the instructions.

[0016] The beneficial effects of this invention are as follows: 1. This invention controls the cylinder to drive the movable plate to deflect around the hinge axis of the support plate, thereby enabling the lifting device, unfolding mechanism, and fireproof components to smoothly rotate and stand upright from a low-profile horizontal stacked state to a vertical working state. This significantly reduces the overall vehicle height and vertical space occupation, effectively reducing the risk of scraping against the top ventilation ducts, lights, and side wall facilities in the limited clearance environment of tunnels. It also significantly improves the mobility and emergency response speed of the equipment in the narrow and enclosed space of tunnels. At the same time, a bottom fireproof cover is added to the bottom of the mounting plate, limiting plate, and side plate. The fireproof skirts, which are distributed in an array and have built-in counterweight chains, hang naturally under gravity, adapting to the uneven tunnel road surface. On the one hand, it fills the gap between the rigid mechanical frame and the uneven ground, and on the other hand, it cuts off the bottom leakage channels of surface flames, high-temperature heat radiation, and toxic fumes. This significantly enhances the comprehensive smoke and fire blocking effect and spatial airtightness of the mobile fire truck in the complex road conditions of tunnels.

[0017] 2. The deployment mechanism of this invention employs a drive motor and a reducer to reduce speed and increase torque. Power is smoothly transmitted to the cross linkage of the scissor structure through the meshing of the main and driven wheels. The synchronous gears at the ends meshing with each other provide proportional constraint on the deflection angle of the linkage, thereby achieving synchronous parallel deployment of the limiting plate and side plate with high rigidity and anti-jamming, ensuring uniform and smooth power transmission during long-stroke extension. Based on this linkage, with the locking groove of one side plate and the locking block of the other side plate, multiple fire-fighting vehicles can be conveniently deployed in a longitudinal array along the tunnel and physically seamlessly spliced ​​when facing long-distance tunnel fires. This effectively compensates for the protective gaps that are easily generated when a single device is stationed independently, and quickly constructs a continuous, closed, large-span flexible fire-resistant and smoke-proof barrier, greatly improving the overall isolation continuity and on-site dispatching efficiency when multiple vehicles are working together to deal with long-section tunnel fires.

[0018] 3. The fireproof component of this invention utilizes the outward movement of the side plate to smoothly pull out the built-in fireproof cover, and simultaneously drives the central shaft to twist the retraction spring to accumulate rebound force. Then, when retracting and resetting, the rebound force is released to achieve unpowered, stable, and automatic winding and storage of the cover. This not only simplifies the system's driving components, but also utilizes the soft magnets built into the upper and lower ends to achieve spontaneous magnetic adhesion between the unfolded cover and the metal frame, effectively alleviating the bulging and deformation of the cover under the strong heat convection and turbulent smoke environment of tunnel fires. At the same time, an installation bracket with a cleaning brush is added at the guide port. Combined with the reserved gap between the external fireproof cover and the storage drum, a physical brushing and follow-up discharge linkage cleaning mechanism is realized in situ during the fireproof cover retrieval to physically sweep away fire ash, molten residue, and gravel debris. This avoids mechanical jamming or cover wear caused by debris compression, ensuring the high reliability and long service life of the equipment in multiple cyclic unfolding and retraction operations under the harsh environment of tunnel fires.

[0022] like Figures 1 to 12 As shown, a mobile fire-resistant train with an deployable fireproof cover and its usage method include a mobile vehicle body 1, a control unit 2, a tilting assembly 3, a lifting device 4, a deployment mechanism 5, and a fireproof component 6. The mobile vehicle body 1 is fixedly equipped with a control unit 2 for controlling the entire fire-resistant train. The control unit 2 includes a main control module, a wireless communication module, and multiple sets of travel detection switches. The main control module is electrically connected to a control cylinder 35, a lifting drive cylinder, and a drive motor 521. Travel detection switches are installed at the extreme positions of the tilting assembly 3, the lifting device 4, and the deployment assembly to provide feedback signals to the main control module, enabling automatic start / stop and limit protection. Operators can send commands to the main control module via a remote control through the wireless communication module to control the equipment and complete the entire deployment process. The retraction action; the flipping component 3 is fixedly installed on the mobile vehicle body 1, and the flipping component 3 is used to drive the lifting device 4, the unfolding component and the fireproof component 6 to switch between a horizontal storage state and a vertical working state; the lifting device 4 is fixedly installed on the flipping component 3, and the lifting device 4 is used to adjust the height of the unfolding mechanism 5; the unfolding mechanism 5 is fixedly installed on the lifting device 4, and the unfolding mechanism 5 is used to drive the fireproof component 6 to unfold, the fireproof component 6 is fixedly installed on the unfolding mechanism 5, and the end of the fireproof cover inside the fireproof component 6 is fixedly connected to the movable part of the unfolding mechanism 5; when the unfolding mechanism 5 is working, it drives the fireproof component 6 to unfold or retract horizontally synchronously through the transmission linkage mechanism to form a continuous fireproof barrier; The lifting device 4 adopts a guide rail and screw lifting mechanism commonly used in the field. This mechanism features smooth lifting, high positioning accuracy, and compact vertical storage size, making it suitable for applications with limited installation space in vehicles. The bottom fixed base of the lifting device 4 is fastened to the upper surface of the movable plate 34 of the flipping assembly 3 by bolts. The mechanism includes parallel vertical guide rails and a transmission screw. The sliding seat is fixedly connected to the transmission nut of the screw and can slide along the vertical guide rails. The bottom surface of the mounting plate 51 of the unfolding assembly is fixedly installed on the sliding seat. The drive motor 521 of the lifting device 4 is connected to the transmission screw, and its control end is electrically connected to the control unit 2. Meanwhile, a driving environment acquisition unit (not shown in the figure) is set on the carrying platform of the mobile vehicle body 1, and a situation monitoring unit is set on the top of the deployment component; the driving environment acquisition unit and the situation monitoring unit are both electrically connected to the control unit 2, and are used for tunnel road condition perception and path auxiliary planning during the driving phase, and for fire observation and situation feedback on the fire-facing side during the deployment operation phase. When the flipping component 3 is in a horizontally stowed state, a driving environment camera, i.e., the driving environment acquisition unit, is fixedly installed on the support platform of the mobile vehicle body 1, inside the flipping bracket 32. The camera's acquisition direction is consistent with the vehicle's driving direction, and its signal output terminal is electrically connected to the control unit 2. As the vehicle travels through the tunnel, the driving environment acquisition unit collects information in real time on road obstacles ahead, tunnel clearance, side wall facilities, and vehicle distribution, and transmits the image data to the control unit 2. The control unit 2 combines the collected environmental information to assist in planning the driving path and predicting obstacles, effectively reducing the risk of scraping and getting stuck while driving in the tunnel and improving the efficiency of maneuvering in narrow tunnel environments. A situation monitoring camera, or situation monitoring unit, is fixedly installed at the top of the central column of the movable panel 34. The camera's acquisition direction is consistent with the fire-facing side of the fire barrier, and its signal output terminal is electrically connected to the control unit 2. The camera's installation height is flush with the top of the barrier after it is deployed, providing a wide field of view. When the fireproof cover is fully deployed and the equipment enters the fire prevention operation state, the situation monitoring camera automatically starts, collecting real-time data on the spread of vehicle fires, the distribution range of open flames, and the diffusion of smoke in the tunnel on the fire-facing side, and transmitting the monitoring images and data back to the control unit 2. Command personnel at the rear can monitor the fire situation in real time through the remote terminal of the control unit 2, without having to send personnel close to the fire area for observation, effectively reducing the safety risks for front-line workers, and facilitating timely adjustments to the protective deployment according to changes in the fire situation.

[0023] During operation, the control unit 2 controls the mobile vehicle 1 to travel to the designated fireproof position. At this time, the control unit 2 controls the flipping component 3 to move. The moving flipping component 3 drives the lifting device 4, the unfolding mechanism 5 and the fireproof component 6 to flip from a horizontal state to a vertical state. Then the lifting device 4 moves, which drives the unfolding mechanism 5 to move up and down to adjust the height. Then the unfolding mechanism 5 moves, and the unfolding mechanism 5 drives the fireproof cover fixedly connected to the movable part to move horizontally or retract synchronously through the transmission linkage mechanism. The unfolded fireproof cover and the fireproof component 6 then form a continuous fireproof barrier. By setting up the flipping component 3, the equipment can be kept horizontally stacked when not in operation, thereby effectively reducing the vehicle's center of gravity and space occupation, and improving the stability and passability of the mobile fire truck in complex road conditions. During the deployment phase, the coordinated action of the flipping component 3 and the lifting device 4 can guide the entire protective mechanism to smoothly transition from a horizontal to a vertical working posture, and flexibly adjust the barrier's height from the ground according to the fire terrain or actual shielding requirements, enhancing its adaptability to uneven terrain. In addition, in conjunction with the transmission linkage mechanism in the unfolding mechanism 5, the fireproof cover can be smoothly and synchronously unfolded laterally, significantly widening the effective protection span of a single device while ensuring the stability of mechanical operation. The entire operation process has a high degree of automation, which helps to quickly and conveniently construct a continuous and targeted spatial fire barrier.

[0024] like Figures 1 to 6As shown, the unfolding mechanism 5 includes a mounting plate 51, a drive mechanism 52, a limiting plate 53, a side plate 54, a driven wheel 55, a driven arm 56, a cross link 57, and a synchronous gear 58. The mounting plate 51 is fixedly mounted on the lifting device 4. Two sets of drive mechanisms 52 are centrally symmetrically fixedly mounted on the mounting plate 51. The limiting plate 53 and the side plate 54 are symmetrically arranged on both sides of the mounting plate 51. The driven wheels 55 are centrally symmetrically rotatably mounted on the mounting plate 51 and mesh with the drive mechanisms 52. One end of the driven arm 56 is fixedly mounted on the driven wheel 55, and the other end of the driven arm 56 is hinged to the cross link 57 near the mounting plate 51. The middle parts of several cross links 57 are hinged to each other to form a scissor structure, and the ends of the cross links 57 are respectively fixedly connected to the synchronous gear 58. The step gear 58 and the synchronous gear 58 at the ends of adjacent cross links 57 mesh with each other. The cross links 57 are rotatably mounted on the mounting plate 51, the limiting plate 53, and the side plate 54 respectively through the rotation shaft of the synchronous gear 58. The drive mechanism 52 is used to drive the driven wheel 55 to rotate, and then drive several cross links 57 to perform scissor motion through the driven arm 56. The meshing transmission of the synchronous gears 58 at the ends is used to extend or fold, so that the limiting plate 53 and the side plate 54 can be synchronously and parallelly unfolded or retracted relative to the mounting plate 51. The two ends of each cross link 57 are coaxially fixedly connected with synchronous gears 58, and the axis of the synchronous gears 58 coincides with the hinge axis of the end of the cross link 57. The synchronous gears 58 at the adjacent ends of two adjacent cross links 57 mesh externally with each other to form an equal angle transmission pair. The mounting plate 51, the limiting plate 53, and the side plate 54 are all equipped with corresponding hinge pins. The synchronous gear 58 at the end of the cross link 57 has a shaft hole in its center and is rotatably mounted on the corresponding plate through the hinge pin. The limiting plate 53 is set between the mounting plate 51 and the side plate 54. On the one hand, it mechanically limits the maximum extension stroke of the scissor lift. On the other hand, it serves as an intermediate support node to improve the structural rigidity of the long-span scissor lift and avoid lateral swaying and jamming during the extension process. During operation, the drive mechanism 52 on the mounting plate 51 starts running. At this time, the running drive mechanism 52 drives the driven wheel 55 meshing with it to rotate. The rotating driven wheel 55 drives the driven arm 56 fixedly connected to it to swing displacement. The swing displacement driven arm 56 applies a pushing or pulling force to the cross link 57 close to the mounting plate 51. The cross link 57 under force performs a scissor opening and closing motion with the central hinge point as the axis. The cross link 57 performing the scissor opening and closing motion drives the synchronous gear 58 fixed at its end to rotate with the change of the link angle. The rotating and meshing synchronous gear 58 provides proportional constraint and power transmission to the deflection angle of the adjacent cross link 57. The cross link 57, constrained by the gear angle and continuously performing scissor extension and retraction, drives the limiting plate 53 and the side plate 54 to translate outward or inward through the end rotating shaft. The translated limiting plate 53 and the side plate 54 then achieve synchronous linkage with the mounting plate 51 and always maintain parallel lateral expansion or retraction action. Through the aforementioned deployment mechanism 5, the rotational power is smoothly converted into the scissor extension and retraction motion of the cross link 57 by the linkage of the drive mechanism 52, driven wheel 55, and driven arm 56. This makes the overall driving process relatively stable and easy to control. At the same time, a synchronous gear 58 is introduced at the end of the cross link 57. The precise meshing of the gears provides proportional constraint on the deflection angle of adjacent links, effectively alleviating the uneven force and motion deviation problems that are prone to occur in traditional multi-stage scissor mechanisms during long-stroke extension, and reducing the risk of jamming during mechanical operation. This gear and link composite transmission design not only ensures the uniform and smooth power transmission, but also enables the limiting plate 53 and the side plate 54 to maintain synchronous linkage and stable parallelism throughout the entire lateral deployment or retraction stroke. This improves the overall structural rigidity and motion accuracy of the deployment mechanism 5 during operation, and helps to enhance the deployment reliability of the equipment in actual working environments.

[0025] like Figure 6 As shown, the drive mechanism 52 includes a drive motor 521, a reducer 522, a drive wheel 523, and a fixed bracket 524. The reducer 522 is fixedly mounted on the output end of the drive motor 521, and the drive wheel 523 is fixedly mounted on the output end of the reducer 522. The drive wheel 523 meshes with the driven wheel 55, thereby driving the driven wheel 55 to drive the unfolding mechanism 5 on the left and right sides to unfold or retract respectively. The drive motor 521 and the reducer 522 are fixedly mounted on the mounting plate 51 through the fixed bracket 524. During operation, the drive motor 521, which is firmly supported on the mounting plate 51 by the fixed bracket 524, starts running. At this time, the running drive motor 521 outputs rotational power and drives the reducer 522 to run. The running reducer 522 converts the high-speed rotational power input by the drive motor 521 into a low-speed, high-torque output. The low-speed, high-torque output then drives the drive wheel 523, which is fixedly installed at the output end of the reducer 522, to rotate smoothly. The rotating drive wheel 523 transmits rotational torque through the physical meshing of its outer edge teeth with the teeth of the driven wheel 55, thereby driving the driven wheel 55, which meshes with it, to rotate synchronously. The rotating driven wheel 55 transmits and distributes power, thereby driving the unfolding mechanisms 5 on the left and right sides to overcome mechanical resistance and perform stable and smooth unfolding or retracting actions.

[0026] By configuring the aforementioned drive mechanism 52, the high-speed output of the drive motor 521 is reduced and torque increased using the reducer 522, providing sufficient and stable driving torque for the system. This helps overcome the frictional resistance of the multi-stage mechanical linkage during movement, making the overall unfolding or retracting action smoother and more controllable. The physical transmission structure with the driving wheel 523 meshing with the driven wheel 55 ensures the accuracy and continuity of the power transmission process, facilitating the even distribution and synchronous driving of power to the left and right sides of the unfolding mechanism 5. Furthermore, the robust support provided by the fixed bracket 524 effectively mitigates the vibration generated by the drive components during load operation, maintaining a stable relative position and meshing state between the various transmission components, thereby improving the operational stability and structural durability of the entire drive transmission system.

[0027] like Figures 8 to 9As shown, the fireproof component 6 includes an external fireproof cover 61, a storage drum 62, a recovery spring 63, a central shaft 64, an internal fireproof cover 65, and a guide port 66. The external fireproof cover 61 is fixedly installed on the outside of the storage drum 62 and is used to protect the storage drum 62. Two storage drums 62 are symmetrically fixedly installed on the mounting plate 51. The storage drum has a hollow structure and the recovery spring 63 is installed on the inner top and inner bottom. The central shaft 64 is fixedly installed at the center of the recovery spring 63. One end of the internal fireproof cover 65 is fixedly installed on the central shaft 64. The other end of the built-in fireproof cover 65 passes through the guide port 66 located on the storage drum 62 and is fixedly connected to the corresponding side plate 54; the built-in fireproof cover 65 is pulled out from the storage drum 62 by the movement of the side plate 54 to form a continuous fire barrier; the built-in fireproof cover 65, the bottom fireproof cover 7 and the fireproof skirt 71 are all made of silicone rubber coated high silica fiber fireproof cloth, which can withstand long-term temperature not lower than 550℃, and the surface is treated with water and oil repellency, and has good flame retardant, heat insulation and anti-aging properties; the thickness of the built-in fireproof cover 65 is 0.8 to 1.2 mm, which takes into account both flexible winding performance and structural strength.

[0028] During operation, as the unfolding mechanism 5 drives the side plate 54 to move outward, the outward-moving side plate 54 generates an outward pulling force on the fixedly connected built-in fireproof cover 65. The built-in fireproof cover 65 under the pulling force is continuously pulled outward through the guide port 66 on the storage drum 62. The pulled-out built-in fireproof cover 65 causes the central shaft 64 inside the storage drum 62 to rotate synchronously. The rotating central shaft 64 then causes the recovery spring 63 installed at the top and bottom of the storage drum 62 to undergo torsional deformation and accumulate rebound force. As the side plate 54 continues to move outward, the built-in fireproof cover 65 is continuously pulled out and unfolded, thus forming a continuous large-area fire barrier. When the fire prevention task is completed and the unfolding mechanism 5 drives the side plate 54 to retract and reset inward, the outward pulling force of the side plate 54 on the built-in fireproof cover 65 is gradually released. At this time, the retractable spring 63, which has undergone torsional deformation, releases the accumulated rebound force. The retractable spring 63, which releases the rebound force, drives the central shaft 64 to rotate in the opposite direction. The central shaft 64, which rotates in the opposite direction, then smoothly winds the built-in fireproof cover 65 in the opposite direction through the guide port 66 and puts it back into the storage drum 62 protected by the external fireproof cover 61. By setting up the aforementioned fireproof component 6, the external fireproof cover 61 physically shields the storage drum 62, which helps to reduce the damage to the core components inside the drum caused by the harsh external fire environment and improves the overall structural durability of the device. One end of the built-in fireproof cover 65 is fixed to the central shaft 64, and the other end is smoothly pulled out through the guide port 66 as the side plate 54 unfolds laterally. This not only enables the rapid and continuous construction of a large-area flexible fireproof barrier, but also achieves good synchronous linkage between the fire-resistant surface and the mechanical frame. In addition, by cleverly utilizing the torsional energy storage characteristics of the retractable spring 63 during the pulling process, a stable self-rebound power is provided when the mechanism is reset, realizing the automatic winding and storage of the built-in fireproof cover 65 without power. This design simplifies the system drive components and reduces operating energy consumption, while also helping to ensure the stability and reliability of the fireproof cover during multiple cycles of unfolding and retracting operations.

[0029] like Figure 8 As shown, the built-in fireproof cover 65 has soft magnets 651 embedded at both its upper and lower ends. This allows the built-in fireproof cover 65 to adhere to the unfolding mechanism 5 after it is unfolded, ensuring its stability. The inclusion of soft magnets 651 at both ends allows the flexible fireproof cover to naturally adhere to the metal frame of the unfolding mechanism 5 after horizontal unfolding, mitigating localized blasting or violent shaking deformation caused by strong heat convection or complex wind pressure in a fire. Simultaneously, the soft magnetic material possesses excellent deformation adaptability, providing auxiliary positioning without significantly interfering with the normal winding and storage process of the fireproof cover within the storage roll 62. This magnetic, non-rigid adhesion design not only improves the overall flatness and operational stability of the fireproof barrier after unfolding but also helps maintain a relatively sealed state between the edge of the fireproof cover and the mechanical frame, thus optimizing the vehicle's spatial isolation and fire-resistant protection.

[0030] like Figure 8 As shown, a mounting bracket 67 is fixedly installed at the guide opening 66, and a cleaning brush 68 is fixedly installed on the mounting bracket 67. A gap for material discharge is provided between the external fireproof cover 61 and the storage drum 62. When the internal fireproof cover 65 is recycled, the cleaning brush 68 brushes away the debris inside the internal fireproof cover 65 and drops it through the gap. The mounting bracket 67 is symmetrically arranged along the upper and lower edges of the guide opening 66. Two sets of cleaning brushes 68 are fixed on the upper and lower mounting brackets 67 respectively, with the brush bristles facing each other and closely fitting the inner and outer surfaces of the internal fireproof cover 65. A long strip-shaped material discharge gap is opened at the bottom of the external fireproof cover 61, directly below the guide opening 66. Ash, leaves and other debris brushed off by the brush fall under the action of gravity and are directly discharged to the outside of the device through the material discharge gap, avoiding accumulation inside the drum and causing jamming.

[0031] By adding a mounting bracket 67 with a cleaning brush 68 at the guide port 66 and reserving a material drop gap between the external fireproof cover 61 and the storage drum 62, the built-in fireproof cover 65 can use the physical brushing action of the brush to promptly peel off and clean fire ash, dead branches and leaves and other debris attached to the surface of the flexible cover when performing the recycling and winding action. At the same time, the debris brushed off can fall out naturally along the material drop gap, which helps to reduce the probability of particulate debris being rolled into the drum along with the fireproof cover, effectively alleviating problems such as mechanical jamming or abnormal wear of the cover that may be caused by the accumulation and compression of debris. This structural linkage self-cleaning design maintains the relative cleanliness of the internal space of the drum, ensuring a smooth recycling process of the protective barrier, improving the reliability of the fireproof component 6 in complex environments, and helping to extend its overall service life.

[0032] like Figure 10 As shown, a bottom fireproof cover 7 is fixedly installed between the mounting plate 51, the limiting plate 53, and the side plate 54. Fireproof skirts 71 are fixedly installed in an array on the bottom fireproof cover 7. Each fireproof skirt 71 is fixedly installed with a counterweight chain 72, which can adapt to uneven fire scene surfaces, seal the gap between the unfolding mechanism 5 and the ground, and cut off the bottom leakage channels of heat radiation and toxic fumes. It stretches and folds synchronously with the unfolding assembly, maintaining continuous bottom shielding throughout the process. The bottom fireproof cover 7 is made of high-temperature resistant flexible fireproof fabric and has an accordion-style folding structure. Its left and right ends are fixed to the inner sides of the corresponding side plates 54, and its middle part is fixedly connected to the bottom of each limiting plate 53 and mounting plate 51 in sequence. When the unfolding assembly unfolds horizontally, the bottom fireproof cover 7 stretches and unfolds synchronously with the translation of each plate, and folds and stores synchronously when it is closed, maintaining continuous bottom shielding throughout the process. The fireproof skirts 71 are arranged in a continuous array along the lower edge of the bottom fireproof cover 7. Each fireproof skirt 71 is equipped with a counterweight chain 72, so that the skirt hangs down naturally under gravity and fits the ground surface, adapting to different tunnel terrains.

[0033] By adding a bottom fireproof cover 7 between the mounting plate 51, the limiting plate 53, and the side plate 54, and arranging fireproof skirts 71 with built-in counterweight chains 72 on it, the flexible fireproof skirts 71 can hang down under the natural gravity pull of the counterweight chains 72 when the device is deployed, thus better adapting to different ground morphologies in the fire scene. This flexible and gravity-driven design effectively fills the gaps that are easily created between the rigid mechanical frame and the irregular ground, and to a certain extent prevents surface fires, high-temperature heat radiation, and toxic smoke from passing through and leaking from the bottom. This not only improves the overall spatial airtightness and isolation continuity of the fire barrier, but also helps to further enhance the comprehensive safety protection effect of the equipment in varied terrain.

[0034] like Figure 7 As shown, the flipping assembly 3 includes a flipping base plate 31, a flipping bracket 32, a support plate 33, a movable plate 34, and a control cylinder 35. The flipping base plate 31 is fixedly installed above the mobile vehicle body 1. The flipping bracket 32 ​​is fixedly installed on the flipping base plate 31. The support plate 33 is fixedly installed on the flipping bracket 32. The movable plate 34 is hinged to the support plate 33. The control cylinder 35 is symmetrically hinged between the movable plate 34 and the lifting base plate. The upper surface of the movable plate 34 is a flat mounting surface. The lifting base plate of the lifting device 4 is fastened to the upper surface of the movable plate 34 by bolts. When the control cylinder 35 extends, it pushes the movable plate 34 to flip upward 90° around the hinge axis of the support plate 33, so that the lifting device 4 and the entire set of components above it switch from a horizontally lying storage state to a vertical working posture. When the control cylinder 35 retracts, it drives the movable plate 34 to flip in the opposite direction and reset, restoring the horizontal storage state.

[0035] During operation, the tilting base plate 31, which is fixedly installed above the mobile vehicle body 1, and its tilting bracket 32 ​​and support plate 33 provide a stable mechanical support foundation for the entire posture conversion action. When the mobile anti-rollover needs to switch from the transport state to the working state, the control cylinder 35, which is symmetrically hinged between the lifting base plate and the movable plate 34, is activated. At this time, the operating control cylinder 35 drives its piston rod to perform a synchronous linear extension action. The linearly extended piston rod applies a continuous and smooth oblique thrust to the force-bearing hinge point on the movable plate 34. Since the movable plate 34 is restricted by the degree of freedom of the hinge pin at the support plate 33, the movable plate 34 subjected to the thrust converts the linear thrust into a rotational force. The torque is applied, and the hinge point on the support plate 33 is used as the fixed axis of rotation to overcome the weight of the equipment above and make an arc-shaped angular deflection. As the piston rod of the control cylinder 35 continues to extend, the movable plate 34, which has undergone angular deflection, smoothly lifts and drives the lifting device 4 and the subsequent complete set of components installed on it, from a horizontal lying state with a low center of gravity to a vertical fire-fighting operation state. Conversely, when the operation is over and the vehicle needs to be retracted, the piston rod of the control cylinder 35 slowly retracts, and the movable plate 34, under the combined constraint of the cylinder pull and the weight of the equipment, smoothly rotates in the opposite direction around the hinge point, thereby driving the entire fire-fighting device to descend again and return to the horizontal stacked storage state. By cleverly utilizing the linear extension and retraction of the control cylinder 35 in conjunction with the hinged rotation of the movable plate 34, the entire massive fire-fighting device can smoothly switch between horizontal transport and vertical working postures. This structure allows the mobile fire truck to maintain a low center of gravity and horizontal storage state during non-working operations, helping to reduce the frontal area and significantly improve the vehicle's driving stability and anti-rollover capability in complex road conditions. At the same time, the symmetrically hinged control cylinder 35 ensures relatively balanced force when providing the tilting power, effectively mitigating the risk of unilateral force or structural torsion deformation that may occur due to the shift in the center of gravity of the upper equipment during take-off and landing. This ensures the smooth and controllable overall posture conversion process of the heavier equipment, thereby improving the safety and mechanical transmission reliability of the entire equipment during actual fire scene deployment and withdrawal operations.

[0036] like Figures 10 to 11 As shown, one side panel 54 is provided with a snap-fit ​​groove 541 for seamless splicing with the fireproof cover of another adjacent mobile fire-resistant vehicle, and the other side panel 54 is provided with a snap-fit ​​block 542 for seamless splicing with the fireproof cover of another adjacent mobile fire-resistant vehicle. Both the snap-fit ​​groove 541 and the snap-fit ​​block 542 are made of high-temperature resistant engineering plastic and are respectively embedded in the outer end faces of the left and right side panels 54. The left and right ends of the built-in fireproof cover 65 extend beyond the end faces of the side panels 54 by 50-80mm, forming an overlapping sealing edge. When the two devices are spliced, the snap-fit ​​block 542 of one side panel 54 is embedded into the snap-fit ​​groove 541 of the other side panel 54 to complete mechanical positioning. At the same time, the overlapping sealing edges of the two devices overlap and fit together, forming a continuous, gapless fireproof barrier to prevent smoke and flying flames from penetrating from the splice.

[0037] By setting corresponding snap-fit ​​slots 541 and snap-fit ​​blocks 542 on one side plate 54 and the other side plate 54 respectively, multiple mobile fire trucks can be conveniently deployed in a parallel array when facing large-area fires. By using the physical plug-in cooperation of the slots between adjacent equipment, a relatively tight splicing and linkage between adjacent fireproof covers can be achieved. This modular connection design effectively fills the protective gaps that are easily generated when multiple individual equipment are stationed independently. To a certain extent, it blocks the penetration and leakage of flying fire, toxic smoke and high-temperature heat radiation from the gaps between equipment, thereby helping to quickly build a continuous, wide and well-isolated large-span fireproof barrier. This not only improves the comprehensive blocking capability of multiple vehicles to respond to large-scale fires, but also makes the on-site dispatching, deployment and splicing operations more efficient and smooth.

[0038] like Figure 12 As shown, a method for using a mobile fire truck with an deployable fireproof cover includes the following steps: S1. Autonomous driving and fixed-point positioning: The control unit 2 receives remote control commands and drives the mobile vehicle 1 to the designated position of the burning vehicle in the tunnel. During this driving phase, the flipping component 3, lifting device 4, unfolding mechanism 5 and fireproof component 6 are kept in a horizontal stacked state to reduce the overall vehicle driving height, adapt to the tunnel clearance restrictions and reduce the space occupied in passage. S2. Posture flipping and height adjustment: After the moving vehicle 1 reaches the predetermined position, the control unit 2 controls the control cylinder 35 in the flipping assembly 3 to move, pushing the movable plate 34 to flip upward around the hinge of the support plate 33, flipping the entire rear device from a horizontal state to a vertical working state; then, the control unit 2 drives the lifting device 4 to move, and adjusts the vertical height of the unfolding mechanism 5 according to the tunnel road surface conditions. S3, Linkage Deployment and Drum Release: Control unit 2 starts drive motor 521, which drives driven wheel 55 and driven arm 56 sequentially through reducer 522 and drive wheel 523, pushing cross linkage 57 to perform scissor extension movement. Synchronous gear 58 meshes to make limit plate 53 and side plate 54 unfold outward; at the same time, built-in fireproof cover 65 is pulled by side plate 54, overcoming the torque of the rewind spring 63 and is continuously pulled out from guide port 66 of storage drum 62; S4. Barrier stability and multi-vehicle splicing: After the built-in fireproof cover 65 is fully deployed, the soft magnets 651 built into its upper and lower ends automatically attach to the deployment mechanism 5 to maintain stability; the fireproof skirt 71 on the bottom fireproof cover 7 adaptively droops and fits the ground under the action of the counterweight chain 72; when facing a fire in a long section of the tunnel, multiple mobile fire-fighting vehicles are dispatched to park side by side along the longitudinal direction of the tunnel, and are seamlessly spliced ​​through the snap-fit ​​groove 541 and snap-fit ​​block 542 on the side plate 54. S5. Automatic retraction and dust removal reset: After the fire prevention task is completed, the control unit 2 controls the drive motor 521 to reverse so that the cross link 57 folds and retracts. The built-in fireproof cover 65 automatically retracts the storage drum 62 under the winding force of the retracting spring 63. When passing the cleaning brush 68, it brushes off the surface debris and drops it from the gap. Finally, the lifting device 4 descends, the control cylinder 35 retracts to restore the device to a horizontal state, and the moving vehicle 1 withdraws and returns to base as instructed.

[0039] The overall working process is as follows: Control unit 2 controls the mobile vehicle 1 to travel to the designated fire handling position inside the tunnel and park it in position; then control unit 2 activates the tilting assembly 3, the symmetrically hinged control cylinder 35 drives the piston rod to extend linearly, pushing the movable plate 34 to deflect at an angle around the hinge pin on the support plate 33, thereby driving the lifting device 4, the unfolding mechanism 5 and the fireproof assembly 6, which are in a horizontal low center of gravity transport state, to tilt smoothly and stand upright to a vertical working posture; then the lifting device 4 is activated to precisely adjust the height of the unfolding mechanism 5 off the ground to adapt to the tunnel road surface conditions and the fireproof and smoke isolation height requirements; then the drive motor 521 on the unfolding mechanism 5 is activated, the power is reduced and increased in torque by the reducer 522, and then driven by the meshing transmission of the drive wheel 523 and the driven wheel 55 to drive the driven arm 5. When the 6-axis swings, the driven arm 56 drives the cross linkage 57 to extend in a scissor-like motion. Under the proportional constraint of the deflection angle by the meshing synchronous gears 58 at the ends, the limiting plates 53 and side plates 54 on both sides move outward in a synchronous and parallel manner relative to the mounting plate 51. During the continuous outward translation of the side plates 54, the traction built-in fireproof cover 65 is continuously pulled outward through the guide port 66 of the storage drum 62. The pulling action drives the central shaft 64 to rotate synchronously, causing the retraction springs 63 at both ends to twist and accumulate rebound force. After unfolding, the cover is automatically attracted to the frame of the unfolding mechanism 5 by the soft magnets 651 built into the upper and lower ends to maintain stability. At the same time, the fireproof skirt 71 on the bottom fireproof cover 7 hangs down naturally under the gravity traction of the counterweight chain 72. The system adapts to uneven tunnel surfaces and seals the gaps at the bottom where smoke and heat radiation leak. When facing a fire in a long tunnel section, multiple fire-resistant vehicles can be seamlessly spliced ​​together using the corresponding locking slots 541 and locking blocks 542 on both sides of the side plate 54 to complete the construction of a continuous fireproof and smoke-proof barrier. When the fire-fighting task is completed and the system is being withdrawn, the drive motor 521 reverses to drive the side plate 54 to retract inward and reset. The outward pulling force of the cover is gradually released. At this time, the retraction spring 63, which is twisted and deformed, releases the accumulated rebound force to drive the central shaft 64 to reverse, so that the built-in fireproof cover 65 is smoothly wound and stored back into the storage drum 62 protected by the external fireproof cover 61. During the recovery process, the cleaning brush 68 on the mounting bracket 67 is used to brush the surface of the cover. The detached fallen leaves and ash are naturally discharged along the reserved gap to prevent jamming. Finally, the control cylinder 35 slowly retracts, and the movable plate 34 rotates in the opposite direction around the hinge point, driving the entire fire-fighting device to land again and reset to the horizontally stacked storage state, completing the entire withdrawal process.
