Description

Technical Field

[0001] This application belongs to the field of fire extinguishing device technology, and more specifically, relates to a fire extinguishing transport vehicle. Background Technology

[0002] Currently, electric vehicles account for an increasingly large proportion of daily life. Compared to spontaneous combustion and fires caused by traffic accidents, fires involving electric vehicles are more difficult to extinguish and can cause prolonged traffic congestion on highways.

[0003] Chinese utility model patent with publication number CN214860732U (publication date: 2021.11.26) discloses a vehicle body device with fire extinguishing function and a vehicle having the same. The device involves installing a new energy vehicle with a power battery that is prone to thermal runaway into the vehicle body, and using water from the water storage chamber inside the device to submerge the power battery on the vehicle body to prevent the power battery from reigniting.

[0004] However, the above solutions have certain shortcomings. Specifically, for vehicles with runaway batteries, it is dangerous to push or drive them into the cargo compartment. They require additional towing equipment such as cranes or trolleys to bring the vehicles into the cargo compartment, which is inconvenient. Summary of the Invention

[0005] This invention provides a fire extinguishing transport vehicle that can carry out fire extinguishing and transport of vehicles with battery runaways with only one vehicle, without the need for additional towing equipment.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a fire extinguishing transport vehicle, including a transport vehicle body and a self-unloading fire extinguishing compartment loaded on the transport vehicle body, wherein the self-unloading fire extinguishing compartment is provided with a storage room for storing fire extinguishing agents and a receiving room for accommodating objects to be extinguished, and the storage room and the receiving room are selectively connected.

[0007] The self-unloading fire truck is also equipped with a lifting support device that extends to the ground. The self-unloading fire truck detaches from the transport vehicle body and is placed on the ground through the lifting support device. The transport vehicle body is equipped with a towing device for dragging the object to be extinguished to the containment chamber.

[0008] Optionally, the lifting support device includes a front lifting outrigger and a rear lifting outrigger. The front lifting outrigger is located on the side of the self-unloading fire truck body facing the front of the transport vehicle body, and the rear lifting outrigger is located on the side of the self-unloading fire truck body away from the front of the transport vehicle body.

[0009] Optionally, the front lifting outrigger includes a transverse hydraulic cylinder installed on the self-unloading fire truck body and a vertical outrigger installed at the end of the transverse hydraulic cylinder; the transverse hydraulic cylinder drives the vertical outrigger to extend out of the side of the transport vehicle body, and the vertical outrigger extends to support the ground.

[0010] Optionally, the self-unloading fire truck has an extension section that extends beyond the rear of the transport vehicle body, with rear lifting outriggers located at the bottom of the extension section and extending to support the ground.

[0011] Optionally, a sprinkler head is provided between the storage room and the containment room, and a fireproof sealed door communicating with the containment room is provided at the rear of the self-unloading fire truck. The self-unloading fire truck is provided with a control room; the control room is provided with control terminals that are respectively connected to the sprinkler head and the fireproof sealed door to open or close the sprinkler head and the fireproof sealed door.

[0012] Optionally, the towing device includes a main hydraulic cylinder and a connecting assembly for connecting the object to be extinguished; the main hydraulic cylinder includes a fixed rod and a telescopic rod slidably disposed at the end of the fixed rod, the end of the fixed rod away from the telescopic rod is hinged to the bottom of the rear side of the chassis of the transport vehicle body, a lifting hydraulic cylinder is hinged between the side wall of the fixed rod and the bottom of the chassis of the transport vehicle body, and the telescopic rod is disposed in the direction away from the front of the transport vehicle body.

[0013] Optionally, the object to be extinguished is a vehicle to be extinguished, and the connecting assembly includes a tow bar, with two sets of clamping mechanisms symmetrically arranged along the extension direction of the tow bar.

[0014] The clamping mechanism includes a movable clamping rod and a clamping hydraulic cylinder. One end of the movable clamping rod is hinged to the side wall of the traction rod. A U-shaped groove for clamping the tire of the vehicle to be extinguished is formed between the ends of the movable clamping rod and the traction rod. The two ends of the clamping hydraulic cylinder are respectively hinged to the side wall of the movable clamping rod and the side wall of the traction rod.

[0015] Optionally, the traction rod is hinged to the end of the telescopic rod away from the side wall of the clamping mechanism.

[0016] Optionally, the opposite sidewalls of the U-shaped slot are provided with bevels that match the tires of the vehicle to be extinguished.

[0017] Optionally, the side wall of the self-unloading fire truck is provided with a filling port that communicates with the containment chamber.

[0018] The advantages of the technical solution in this application compared to the prior art are as follows:

[0019] When facing a fire truck, the transport vehicle carries the self-dumping fire truck to the scene. The self-dumping fire truck compartment is raised and detached from the transport vehicle via a lifting support device. The transport vehicle then drives away from the self-dumping fire truck compartment, which is then lowered back to the ground by the lifting support device. The transport vehicle then tows the fire truck to be extinguished into the compartment of the self-dumping fire truck compartment using a towing device. The extinguishing agent in the storage compartment can then be used to extinguish the fire on the fire truck.

[0020] The entire process requires no additional towing equipment; the fire extinguisher transport vehicle itself can complete the towing, loading, and firefighting processes, demonstrating its high functionality. Furthermore, because the self-unloading fire extinguisher compartment can be lowered to the ground rather than being on the transport vehicle itself, the vehicle to be extinguished can be towed into the self-unloading compartment without needing to be carried to a higher location, reducing operational difficulty. In addition, after the vehicle to be extinguished is placed in the compartment, the self-unloading fire extinguisher compartment can be raised again via a lifting support device and loaded onto the transport vehicle itself. The transport vehicle can then promptly drive away with the vehicle to be extinguished, handling other vehicles while on the move, avoiding prolonged road congestion.

[0021] The fire-fighting transport vehicle of this application is not limited to fire-fighting of vehicles. It can also be used to transfer objects that need to be transferred in a timely manner, such as burning shelves and pallets, by embedding them into the self-unloading fire-fighting vehicle compartment through a towing device. It has a wide range of applications. Attached Figure Description

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] The present application will now describe a fire extinguishing transport vehicle provided in its embodiments.

[0035] Example:

[0036] This embodiment provides a fire extinguishing transport vehicle, based on... Figures 1 to 3As shown, the device includes a transport vehicle body 1 and a self-unloading fire extinguisher compartment 2 loaded on the transport vehicle body 1. The self-unloading fire extinguisher compartment 2 is equipped with a storage chamber 201 for storing extinguishing agents and a receiving chamber 202 for containing objects to be extinguished. Different extinguishing agents, such as water or liquid nitrogen, can be used for different objects. The storage chamber 201 and the receiving chamber 202 are selectively connected. When an object to be extinguished enters the receiving chamber 202, the extinguishing agent in the storage chamber 201 enters the receiving chamber 202 to extinguish the fire.

[0037] Based on the above structure, the self-unloading fire truck body 2 is also equipped with a lifting support device that extends to support the ground, while the transport vehicle body 1 is equipped with a towing device 3 for dragging the object to be extinguished into the containment chamber 202. The self-unloading fire truck body 2 can be connected to the transport vehicle body 1 via a pin or twist lock. When the fire truck enters the treatment site, the pin or twist lock is first opened to separate the self-unloading fire truck body 2 from the transport vehicle body 1. Then, the lifting support device extends to support the ground, lifting the self-unloading fire truck body 2 away from the transport vehicle body 1. The transport vehicle body 1 drives away, and the lifting support device then lowers the self-unloading fire truck body 2, unloading it from the transport vehicle body 1 onto the ground. At this time, the transport vehicle body 1 uses the towing device 3 to drag the object to be extinguished into the containment chamber 202, and fire extinguishing begins.

[0038] Since the entire process requires no additional towing equipment, the fire extinguishing transport vehicle itself can complete the towing, loading, and fire extinguishing processes, demonstrating strong functionality. Simultaneously, because the self-unloading fire extinguishing vehicle compartment 2 can be lowered to the ground instead of being on the transport vehicle body 1, the object to be extinguished does not need to be carried to a high place before being towed into the self-unloading fire extinguishing vehicle compartment 2, reducing operational difficulty. Furthermore, after the vehicle to be extinguished is placed in the receiving compartment 202, the self-unloading fire extinguishing vehicle compartment 2 can be raised again via a lifting support device and loaded onto the transport vehicle body 1, secured by pins or twist locks. The transport vehicle body 1 can then promptly drive away with the vehicle to be extinguished, handling the vehicle while driving, avoiding prolonged road congestion. The fire extinguishing transport vehicle of this application is not limited to fire extinguishing of vehicles; it can also be used to transfer objects that need to be moved quickly, such as burning shelves or pallets, by embedding them into the self-unloading fire extinguishing vehicle compartment 2 using the towing device 3, making it widely applicable.

[0039] Furthermore, based on Figure 1 and Figure 3 As shown, the lifting support device includes a front lifting outrigger 203 and a rear lifting outrigger 207. The front lifting outrigger 203 is located on the side of the self-unloading fire truck body 2 facing the front of the transport vehicle body 1, and the rear lifting outrigger 207 is located on the side of the self-unloading fire truck body 2 away from the front of the transport vehicle body 1. The front lifting outrigger 203 and the rear lifting outrigger 207 lift and lower to drive the self-unloading fire truck body 2.

[0040] Among them, based on Figure 3 As shown, the front lifting outrigger 203 includes a transverse hydraulic cylinder 204 mounted on the self-unloading fire truck body 2 and a vertical outrigger 205 mounted on the end of the transverse hydraulic cylinder 204. The transverse hydraulic cylinder 204 can be a double-piston hydraulic cylinder, with the vertical outrigger 205 mounted on the end of each of its two pistons. The vertical outrigger 205 is the outrigger used by existing engineering vehicles to support the vehicle on the ground. When the self-unloading fire truck body 2 needs to be unloaded, the transverse hydraulic cylinder 204 drives the vertical outrigger 205 to extend beyond the side of the transport vehicle body 1, avoiding the transport vehicle body 1, and then the vertical outrigger 205 extends downwards to support the ground, lifting the self-unloading fire truck body 2. Of course, in other embodiments, the transverse hydraulic cylinder 204 can also adopt a single-piston structure, and there can be two of them, arranged back-to-back, with the vertical outrigger 205 mounted on the piston end of each transverse hydraulic cylinder 204.

[0041] based on Figure 1 and Figure 2 As shown, the self-unloading fire truck body 2 has an extension section 206 that partially extends beyond the rear of the transport vehicle body 1. This means the self-unloading fire truck body 2 extends beyond the rear of the transport vehicle body 1 to allow the rear lifting outriggers 207 to avoid obstructing the transport vehicle body 1. The rear lifting outriggers 207 are located at the bottom of the extension section 206 and extend to support the ground to lift the self-unloading fire truck body 2. Because the fireproof sealing door 209 is located at the rear of the self-unloading fire truck body 2, it cannot be used with the same outrigger structure extending to both sides as the front lifting outriggers 203, otherwise it would obstruct the fireproof sealing door 209.

[0042] Furthermore, based on Figure 2 As shown, a sprinkler head 208 is installed between the storage chamber 201 and the receiving chamber 202. A fireproof sealed door 209, connected to the receiving chamber 202, is installed at the rear of the self-unloading fire truck 2. The self-unloading fire truck 2 also includes a control room 210. The control room 210 contains control terminals connected to both the sprinkler head 208 and the fireproof sealed door 209. These control terminals can be used for control via buttons or touchscreens. The control terminals control the opening and closing of the sprinkler head 208 and the fireproof sealed door 209. Controlling the opening and closing of the sprinkler head 208 selectively connects the storage chamber 201 and the receiving chamber 202. The method of controlling the sprinkler head 208 and the fireproof sealed door 209 is existing technology and will not be described further. In use, after the self-unloading fire truck 2 is lowered to the ground, the control terminal opens the fireproof sealed door 209. The transport vehicle body 1 then uses the towing device 3 to pull the object to be extinguished into the receiving chamber 202, and subsequently closes the fireproof door 209. After closing, open nozzle 208, and the extinguishing agent in storage chamber 201 can be sprayed out through nozzle 208 to extinguish the fire on the object to be extinguished.

[0043] In this embodiment, based on Figure 2 As shown, both the storage compartment 201 and the control compartment 210 are located at the end of the self-unloading fire truck 2 facing the front, with the storage compartment 201 located on top of the control compartment 210. In other embodiments, based on Figure 4 As shown, the storage chamber 201 can also be located on top of the receiving chamber 202, with nozzles 208 distributed on the top wall of the receiving chamber 202 to spray the extinguishing agent more evenly. However, this method will raise the center of gravity of the entire self-unloading fire truck 2, and the vehicle stability will be slightly lower than... Figure 2 The scheme shown.

[0044] Furthermore, based on Figure 1 , Figure 5 and Figure 6 As shown, the towing device 3 includes a main hydraulic cylinder 301 and a connecting assembly for connecting the object to be extinguished. The main hydraulic cylinder 301 includes a fixed rod 302 and a telescopic rod 303 slidably disposed at the end of the fixed rod 302. The end of the fixed rod 302 away from the telescopic rod 303 is hinged to the bottom of the rear side of the chassis of the transport vehicle body 1. A lifting hydraulic cylinder 304 is hinged between the side wall of the fixed rod 302 and the bottom of the chassis of the transport vehicle body 1. The telescopic rod 303 is arranged in the direction away from the front of the transport vehicle body 1.

[0045] In actual installation, the hinged connections between the fixed rod 302 and the lifting hydraulic rod and the chassis of the transport vehicle both need to be made from the bottom of the chassis, which is inconvenient. Therefore, the tow unit 3 can be equipped with a front crossbeam 310 and a rear crossbeam 311, both ends of which have connecting plates 312. The end of the fixed rod 302 away from the telescopic rod 303 is hinged to the side wall of the front crossbeam 310. At the same time, the rear crossbeam 311 is located on the top side of the fixed rod 302, and a lifting hydraulic cylinder 304 is hinged between the fixed rod 302 and the side wall of the rear crossbeam 311. After the entire tow unit 3 is assembled, the front crossbeam 310 and the rear crossbeam 311 are both connected to the bottom of the chassis of the transport vehicle body 1 by mounting plate bolts. The connecting plates 312 at both ends of the front crossbeam 310 and the rear crossbeam 311 are located on both sides of the chassis of the transport vehicle, making side bolt connection convenient.

[0046] During the movement of the fire extinguisher transport vehicle, both the lifting hydraulic cylinder 304 and the main hydraulic cylinder 301 are in a retracted state, and the entire towing device 3 is stored at the bottom of the chassis of the transport vehicle body 1. When it is necessary to tow the object to be extinguished, the main hydraulic cylinder 301 extends to extend the connecting assembly beyond the rear end of the transport vehicle body 1, and the height of the connecting assembly is adjusted by the extension and retraction of the lifting hydraulic cylinder 304. After the connecting assembly is connected to the object to be extinguished, the object is pushed into the self-unloading fire truck compartment 2, which is already placed on the ground, by reversing the vehicle. The entire towing device 3 is directly installed on the transport vehicle body 1, without the need for an additional towing vehicle or on-site installation after arriving at the scene, thus reducing accident handling time.

[0047] Furthermore, in this embodiment, the object to be extinguished is a vehicle to be extinguished. Correspondingly, based on... Figure 5 and Figure 6 As shown, the connecting assembly includes a towing rod 305, and two sets of clamping mechanisms are symmetrically arranged along the extension direction of the towing rod 305. The two sets of clamping mechanisms are used to suspend the two front wheels of the vehicle to be extinguished. After the front wheels of the vehicle are suspended, the transport vehicle body 1 reverses and pushes the vehicle into the self-unloading fire truck compartment 2. The clamping mechanism includes a movable clamping rod 306 and a clamping hydraulic cylinder 307. The movable clamping rod 306 is L-shaped, with one end hinged to the side wall of the towing rod 305. A U-shaped groove 308 for clamping the tires of the vehicle to be extinguished is formed between the ends of the movable clamping rod 306 and the towing rod 305. The two ends of the clamping hydraulic cylinder 307 are hinged to the side walls of the movable clamping rod 306 and the towing rod 305, respectively. The clamping hydraulic cylinder 307 extends and retracts, causing the U-shaped groove 308 to open and close.

[0048] In use, the clamping hydraulic cylinder 307 first retracts, and the U-shaped slot 308 opens. The connecting assembly is then inserted from the bottom of the front of the vehicle to be extinguished by reversing or extending the main hydraulic cylinder 301. When the two side walls of the drawbar 305 abut against the two front wheels of the vehicle to be extinguished, the clamping hydraulic cylinder 307 extends, and the drawbar 305 and the movable clamping rod 306 clamp the wheels. At this time, the lifting hydraulic cylinder 304 retracts, raising the front of the vehicle to be extinguished. After the vehicle to be extinguished is pushed into the self-unloading fire truck compartment 2, the clamping hydraulic cylinder 307 extends and retracts, and the connecting assembly can be pulled out from the bottom of the vehicle. The extension and retraction of the clamping hydraulic cylinder 307, the main hydraulic cylinder 301, and the lifting hydraulic cylinder 304 can all be operated remotely. The operating end is located in the cab of the transport vehicle body 1. The entire process does not require manual connection of the connecting assembly to the vehicle to be extinguished, and rescue personnel do not need to approach the vehicle to be extinguished, making the operation safe.

[0049] Preferably, based on Figure 5As shown, the towing rod 305 is hinged to the end of the telescopic rod 303 on the side wall away from the clamping mechanism. Since the vehicle to be extinguished is not directly facing the fireproof sealing door 209, turning is inevitable during the process of pushing the vehicle into the self-unloading fire truck compartment 2. However, the front wheels of the vehicle are off the ground, making turning inconvenient. Therefore, the towing rod 305 and the telescopic rod 303 are hinged together, allowing the main hydraulic cylinder 301 and the connecting assembly to rotate during the pushing process, facilitating the directional adjustment of the vehicle to be extinguished.

[0050] Preferably, based on Figure 5 As shown, the U-shaped slot 308 has inclined surfaces 309 on its opposite sidewalls that match the tires of the vehicle to be extinguished. The two opposite inclined surfaces 309 can be placed more easily under the wheels of the vehicle to be extinguished and can lift and suspend the wheels.

[0051] Furthermore, based on Figure 3 As shown, the side wall of the self-unloading fire truck compartment 2 is equipped with a filling port 211 that communicates with the housing compartment 202. The filling port 211 can be connected to external pipelines such as fire hoses. After the fire truck returns with the object to be extinguished, additional coolant can be sprayed into the compartment through the filling port 211, depending on the condition of the object. The object can then be towed out after it is safe to do so.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
