Description

Technical Field

[0001] This invention relates to the field of traffic safety technology, specifically to a road clearing vehicle. Background Technology

[0002] With increasing environmental awareness and continuous technological development, electric vehicles (EVs) have become an important part of modern transportation and are rapidly gaining popularity. However, along with the increase in the number of EVs, the number of EV-related fires is also on the rise. Compared with fires involving traditional gasoline-powered vehicles, EV fires have unique dangers.

[0003] When an electric vehicle battery pack catches fire, the combustion process often lasts a long time and carries a high risk of thermal runaway and explosion. Once the fire gets out of control, it can easily spread to nearby parked vehicles or other flammable materials, creating a domino effect and causing greater property damage and safety threats. Furthermore, the combustion of electric vehicle batteries and their internal materials produces large amounts of toxic gases and dense smoke. These toxic substances diffuse with the smoke, posing a serious threat to the lives of people on site and causing severe air pollution to the surrounding environment.

[0004] Existing fire extinguishing methods have limited effectiveness in suppressing electric vehicle battery fires. Research and practice show that to effectively extinguish electric vehicle battery fires and prevent further thermal runaway, it is usually necessary to completely submerge the battery in water, thereby suppressing combustion by absorbing a large amount of heat and isolating oxygen. However, in practical applications, achieving rapid and effective complete submersion of the battery pack of a burning electric vehicle is a challenging task, especially in the initial stages of emergency response.

[0005] Furthermore, while extinguishing battery fires by immersion in water can effectively control the blaze, the large amount of water used in the process dissolves various harmful substances released from burning or damaged batteries, including but not limited to heavy metals, electrolyte components, and other toxic compounds. If these contaminated extinguishing waste liquids are discharged directly without proper treatment, they will cause serious and long-term pollution to soil, water sources, and other environmental factors, and may even enter the food chain, posing a significant threat to ecosystems and human health. Summary of the Invention

[0006] The present invention aims to solve the technical problems of low fire extinguishing efficiency, difficulty in quickly and effectively suppressing or immersing fires, generation of large amounts of polluting waste liquid that is difficult to treat, and high environmental pollution risk in the treatment of electric vehicle fires in the prior art.

[0007] To achieve the above objectives, the present invention provides a road clearing vehicle, which includes a vehicle body and further includes:

[0008] Fire Extinguishing Cover: This fire extinguishing cover can be movably mounted on the vehicle body and can be easily deployed above a disabled vehicle. Its bottom is designed to be open, but it can be tightly fastened to the road surface during operation, thus forming a relatively enclosed space inside the fire extinguishing cover to accommodate the disabled vehicle. This enclosed space is structurally or functionally divided into a parking compartment and a cleaning compartment distributed vertically.

[0009] Heat exchange components: Installed on the fire extinguishing hood, they are used to exchange heat with air, water, smoke and other substances in the confined space, aiming to reduce the internal temperature and suppress combustion or thermal runaway.

[0010] Lifting mechanism: This is installed to lift the disabled vehicle from the ground to a parking compartment in the upper part of the enclosed space, facilitating subsequent handling and space separation.

[0011] Isolation mechanism: Used to effectively separate the upper parking room from the lower cleaning room when needed, enabling zoned management.

[0012] Cleaning mechanism: Used to clean the ground within the engagement area of ​​the fire extinguisher cover and remove residue.

[0013] Water storage assembly: Located on the vehicle body, it includes at least one fire-suppressing water tank and one cooling water tank. The fire-suppressing water tank is connected to a confined space via pipelines and is used to supply water for fire extinguishing or fire suppression; the cooling water tank is connected to the heat exchange assembly and provides it with a cooling medium.

[0014] With the aforementioned structure, the fire extinguishing cover, once enclosing a burning vehicle, creates a relatively enclosed environment. Water is injected into the cover from the flame-suppressing water tank, effectively immersing or continuously spraying the vehicle, especially the battery area, achieving efficient fire extinguishing or flame suppression. Simultaneously, the heat exchange components continuously operate, dissipating heat from within the cover and carrying it away with the cooling water, further controlling the temperature and preventing thermal runaway. More importantly, wastewater generated during firefighting is confined inside the fire extinguishing cover and can be collected through subsequent structures, preventing direct discharge into the environment.

[0015] Preferably, a gantry frame is slidably connected to the vehicle body along its length, and a first horizontal power assembly is connected between the vehicle body and the gantry frame;

[0016] A first lifting seat is slidably connected to the gantry frame along the vertical direction, and a first lifting power component is connected between the first lifting seat and the gantry frame.

[0017] The first lifting platform is provided with a load-bearing beam extending along the length of the vehicle body. The fire extinguishing cover is slidably connected to the load-bearing beam, and a second horizontal power assembly is connected between the fire extinguishing cover and the first lifting platform.

[0018] Preferably, the lifting mechanism includes support columns symmetrically arranged inside the fire extinguishing hood, a second lifting seat is slidably connected to the support column in the vertical direction, and a second lifting power assembly is connected between the second lifting seat and the support column;

[0019] The second lifting seat is hinged with a support arm that can swing in the horizontal direction, and a swinging power component is connected between the support arm and the second lifting seat.

[0020] Preferably, the isolation mechanism includes a base plate that is slidably connected to the fire extinguishing hood along the length of the vehicle body, and a third horizontal power assembly connecting the base plate and the fire extinguishing hood.

[0021] Preferably, the heat exchange assembly includes a meandering hot water pipe and heat exchange fins disposed on the hot water pipe.

[0022] Preferably, a clean water collection pipe is connected between the heat exchange component and the cooling water tank, and the clean water collection pipe is equipped with a first control valve and a cooling device.

[0023] Preferably, a circulating water pipe is connected between the heat exchange component and the cleaning chamber, and a sewage collection pipe is connected between the flame-suppressing water tank and the cleaning chamber, with a second control valve installed on the sewage collection pipe.

[0024] Preferably, the cleaning mechanism includes a drive roller and a driven roller rotatably connected to the bottom end of the base plate, and a cleaning brush belt connecting the drive roller and the driven roller, wherein the drive roller is connected to a cleaning motor.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. Reduced risk of fire spread: The enclosed space formed by the fire extinguishing cover confines the fire and high temperature inside the cover, effectively preventing the flames and heat from spreading to surrounding vehicles or combustibles, avoiding the occurrence of "fire spreading to multiple buildings", thereby reducing secondary disasters and greater property losses.

[0027] 2. Reduced diffusion of toxic gases and smoke, and reduced air pollution: The airtight nature of the fire extinguishing cover significantly reduces the direct emission of toxic gases and dense smoke generated by battery combustion into the atmosphere, protecting the safety of on-site rescue personnel and reducing pollution to the surrounding air environment.

[0028] 3. Effective control and collection of contaminated wastewater, preventing secondary environmental pollution: Firefighting wastewater containing harmful substances generated during the firefighting process is confined to the cleaning chamber inside the fire extinguishing hood and collected through subsequent structures such as recovery branches, avoiding direct discharge into the environment and causing soil and water pollution. The cleaning organization can also perform preliminary treatment of residues on the ground. Attached Figure Description

[0045] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0046] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0047] As attached Figure 1-6 The road clearing vehicle shown includes a vehicle body 1 and a movable fire extinguishing cover 11 mounted on the vehicle body 1. The fire extinguishing cover 11 can be moved by a gantry 14 mounted on the vehicle body 1.

[0048] In this embodiment, the gantry 14 is specifically embodied as a telescopic frame structure, mounted on the chassis guide rails of the vehicle body 1. Its telescopic movement is powered by a first horizontal power component, which is a hydraulic cylinder. This first horizontal power component is controlled by the vehicle's hydraulic system and can precisely drive the gantry 14 to slide out or retract along the length of the vehicle body 1. Figure 1 As shown in steps S1 to S2, the gantry 14 moves the entire fire extinguishing cover 11 from the transport position of the vehicle body 1 to the ground working area behind the vehicle. Furthermore, the gantry 14 typically also has an overall lifting function to smoothly place the fire extinguishing cover 11 on the ground and cover obstructing vehicles. The gantry 14 is equipped with a first lifting seat 142 slidably connected in the vertical direction. The first lifting seat 142 has a load-bearing beam 143 extending along the length of the vehicle body 1, and the fire extinguishing cover 11 is slidably connected to the load-bearing beam 143. A first lifting power assembly 141 is connected between the first lifting seat 142 and the gantry 14. The first lifting power assembly 141 includes a rotatable first lead screw, which is threadedly connected to the first lifting seat 142. The first lifting power assembly 141 also includes a first lifting motor that drives the first lead screw to rotate. A second horizontal power assembly 116 is connected between the fire extinguishing cover 11 and the first lifting seat 142. The second horizontal power assembly 116 is also a hydraulic cylinder. The movable end of the second horizontal power assembly 116 is fixedly connected to the fire extinguishing cover 11. The second horizontal power assembly 116 can make the fire extinguishing cover 11 move closer to or further away from the first lifting seat 142.

[0049] The fire extinguishing hood 11 itself is a hood structure with a robust outer shell, preferably made of high-temperature resistant and impact-resistant metal or composite material. Its internal clearance is sufficient to accommodate a common passenger electric vehicle, forming a relatively enclosed working space. The heat exchange assembly 13 includes a meandering hot water pipe 131 and heat exchange fins 132 provided on the hot water pipe 131. The heat exchange assembly 13 is integrated and installed on the top or upper side wall of the fire extinguishing hood 11 to ensure effective contact and exhaust of the high-temperature gas accumulated inside the hood.

[0050] The base plate 15 is slidably connected to the fire extinguishing cover 11 and the load-bearing beam 143. A first lifting power assembly 141 is installed on the gantry frame 14. The movable end of the first lifting power assembly 141 is connected to a first lifting seat 142, driving the first lifting seat 142, along with the base plate 15 and the fire extinguishing cover 11, to move along the height direction of the vehicle body 1. The periphery of the base plate 15 is designed with a sealing structure (e.g., a high-temperature resistant and corrosion-resistant flexible sealing strip). When the base plate 15 is fully inserted into the lower part of the fire extinguishing cover 11, the sealing structure at its edge can tightly fit against the inner wall of the fire extinguishing cover 11, thereby reliably dividing the space inside the cover into an upper parking compartment 111 for accommodating vehicles and fire extinguishing water, and a lower cleaning compartment 112 located below the base plate 15 for ground cleaning operations.

[0051] The base plate 15 is provided with a sliding groove 151 extending along the length of the vehicle body 1, and a rack 152 is provided in the sliding groove 151; the third horizontal power assembly includes a drive motor 114, and a sliding gear 115 that meshes with the rack 152 is fixedly installed at the output end of the drive motor 114. The base plate 15 can be moved relative to the fire extinguishing cover 11 by the drive motor 114.

[0052] The fire extinguishing cover 11 has a support column 113 inside, and the bottom panel of the support column 113 is higher than the base plate 15 to avoid interference between them. A second lifting seat 1131 is slidably connected to the support column 113 in the vertical direction. A support arm 1132 that can swing in the horizontal direction is hinged to the second lifting seat 1131. A second lifting power assembly 1133 is connected between the second lifting seat 1131 and the support column 113. The second lifting power assembly 1133 includes a rotatable second lead screw, which is threadedly connected to the second lifting seat 1131. The second lifting power assembly 1133 also includes a second lifting motor that drives the second lead screw to rotate. A swinging power component 1134 is connected between the support arm 1132 and the second lifting seat 1131. The swaying power component 1134 controls the opening and closing of the support arm 1132. When the base plate 15 is about to be inserted into the fire extinguishing cover 11, the support arm 1132 first opens to make room for clearance, and then closes to lift the vehicle. After the fire is initially controlled, the support column 113 will lift the entire obstacle vehicle upwards a certain distance, so that its bottom is completely away from the plane where the base plate 15 is about to be inserted, thereby making room for the insertion of the base plate 15.

[0053] The vehicle body 1 is equipped with a water storage assembly 12, which includes a fire-suppressing water tank 121 and a cooling water tank 122. The fire-suppressing water tank 121 stores fire-fighting water for extinguishing and suppressing fire; the cooling water tank 122 stores cooling medium for cooling circulation of the heat exchange assembly 13. A first water supply pipe is connected between the fire-suppressing water tank 121 and the fire extinguishing cover 11. A first water pump is installed on the first water supply pipe, which can inject a large amount of fire-suppressing water into the fire extinguishing cover 11 in a uniform manner to submerge the obstructing vehicle.

[0054] A second water supply pipe is provided between the cooling water tank 122 and the heat exchange assembly 13. A second water pump is installed on the second water supply pipe. The second water pump can transport the cooling water in the cooling water tank to the heat exchange assembly 13, so that the cooling water flows through the heat exchange assembly 13 and carries away the heat on the heat exchange assembly 13. The cooling water that has absorbed the heat then flows out of the heat exchange assembly 13. In order to ensure the stability of the water temperature inside the fire extinguishing hood 11, a cooling device 125 is provided on the clean water collection pipe 123. The cooling device 125 is specifically a spray cooling tower. The structure of the spray cooling tower is known to those skilled in the art, so it will not be described in detail here. The heat is dissipated into the atmosphere through the cooling device 125.

[0055] The clean water collection pipe 123 is responsible for directing the water in the heat exchange assembly 13 to the cooling water tank 122. The wastewater collection pipe 124 is responsible for pumping the potentially hazardous wastewater collected in the cleaning chamber 112 back to the flame-suppressing water tank 121 for safe temporary storage. A third water pump is installed on the wastewater collection pipe 124, which is used to pump the wastewater from the cleaning chamber 112 to the flame-suppressing water tank 121.

[0056] A circulating water pipe 126 connects the heat exchange component 13 and the cleaning chamber 112. The circulating water pipe 126 is used to transport the high-temperature water flowing through the heat exchange component 13 to the cleaning chamber 112. A first control valve is installed on the clean water collection pipe 123, and a second control valve is installed on the sewage collection pipe 124. When the second control valve is closed and the first control valve is opened, the clean water collection pipe 123 introduces the outlet water of the heat exchange component 13 into the cooling water tank 122 instead of flowing into the cleaning chamber 112; while when the first control valve is closed and the second control valve is opened, the outlet water of the heat exchange component 13 is introduced into the cleaning chamber 112, and the sewage in the cleaning chamber 112 is drawn back to the flame-suppressing water tank 121 through the sewage collection pipe 124.

[0057] After completing a series of preliminary steps, including extinguishing and suppressing the fire on the obstructing vehicle, lifting it (via support column 113), and inserting the base plate (forming parking chamber 111 and cleaning chamber 112), the road clearing vehicle immediately initiates the ground cleaning process. The operator issues a command through the control system to activate the cleaning mechanism. This mechanism mainly includes a drive roller 154 and a driven roller rotatably connected to the bottom of the base plate 15, as well as a cleaning brush belt 153, where the drive roller 154 is driven by a cleaning motor 155. At this time, various residues from the vehicle combustion may remain on the ground inside the cleaning chamber 112, such as battery electrolyte, molten plastic rubber, and oil stains. To more effectively remove these contaminants, cooling water carrying heat energy from the heat exchange component 13 and at a high temperature is transported to the cleaning chamber 112 through the circulating water pipe 126, and the continuously operating cleaning brush belt 153 performs a powerful and continuous mechanical scrubbing of the ground.

[0058] Higher water temperatures significantly soften viscous or semi-solid contaminants, such as molten plastics and rubber, reducing their adhesion. Warm water has a stronger dissolving ability for certain soluble or partially soluble electrolyte residues and combustion products. For oily stains, warm water effectively reduces their viscosity, making them easier to wash away; furthermore, warm water penetrates more easily into the tiny gaps between the stain and the ground, helping to break down the stain's adhesion structure, and combined with the physical action of the brush bristles, achieving a more thorough removal. Compared to using cold water, the thermal energy of warm water significantly enhances its ability to remove stubborn stains. The cleaning process is faster, the cleaning effect is more thorough, and it can better restore the cleanliness of the accident scene.

[0059] The following is a detailed explanation of the workflow of this embodiment (refer to...). Figure 1 and Figure 2 ):

[0060] Transport status (s1): The lifting mechanism, isolation mechanism, and clearing mechanism are all fully mounted on the gantry 14 at the rear of the road clearing vehicle body 1. The vehicle is in a driving or standby state.

[0061] Deployment preparation (s2): After arriving at the accident site, the first horizontal power unit is activated to smoothly move the gantry 14, together with the first lifting seat 142, the load-bearing beam 143 and the fire extinguishing cover 11 carried on it, to the rear of the vehicle, and the fire extinguishing cover 11 reaches the first working position.

[0062] Fire extinguishing cover 11 preparation (s3): The second horizontal power assembly 116 is further activated. The first horizontal power assembly 116 pushes the fire extinguishing cover 11 to move backward relative to the base plate 15 and the load-bearing beam 143, so that the fire extinguishing cover 11 reaches the second working position, and the bottom end of the fire extinguishing cover 11 is open to accommodate the disabled vehicle.

[0063] Fire extinguishing with a cover (s4): The first lifting power component 141 of the gantry frame 14 lowers the fire extinguishing cover 11 via the first lifting seat 142, covering the burning obstacle vehicle on the ground (shown by the dotted line in the figure). Then the water storage component 12 is activated, and the fire suppression water tank 121 supplies water to the fire extinguishing cover 11 for fire extinguishing or fire suppression.

[0064] Base plate insertion (s5): After the fire weakens and the heat exchange component 13 controls the internal temperature of the fire extinguishing cover 11 to a certain extent, the support column 113 inside the fire extinguishing cover 11 is activated to lift the obstructing vehicle to a certain height. After the support arm 1132 on the support column 113 rotates to a certain angle, it abuts against the chassis of the disabled vehicle. Then, the second lifting seat 1131 drives the support arm 1132 to move upward, ultimately lifting the vehicle.

[0065] Furthermore, with the vehicle raised, the floor plate 15 moves towards the fire extinguishing hood 11 under the action of the third horizontal power component until it is fully inserted into the fire extinguishing hood 11, with its edges tightly fitted against the inner wall of the hood 11, forming an effective seal. In this way, the vehicle and most of the fire extinguishing water are enclosed in the parking compartment 111 above the floor plate 15, while the space below the floor plate 15 becomes the cleaning compartment 112. At this time, the cleaning brush belt 153 can be activated, and the second control valve can be opened, thereby cleaning the ground while simultaneously pumping the wastewater accumulated in the cleaning compartment 112 back to the fire suppression water tank 121 through the wastewater collection pipe 124. After the ground is cleaned (specifically, the operator can judge the cleaning status by observing the clarity of the water emanating from the sewage collection pipe 124; when the water emanating from the sewage collection pipe 124 becomes relatively clear, the ground is considered cleaned), close the second control valve and open the first control valve. The water emanating from the heat exchange component 13 is introduced into the cooling water tank 122 through the clean water collection pipe 123. The cooling device 125 on the clean water collection pipe 123 cools the flowing clean water, which then flows into the cooling water tank 122, thereby realizing the recycling of water.

[0066] Fire extinguishing cover 11 retraction (s6): Under the action of the second horizontal power assembly 116, the fire extinguishing cover 11, together with the base plate 15, retracts to the first working position.

[0067] Fire extinguishing cover 11 is lifted (s7): Under the action of the first lifting power component 141, the fire extinguishing cover 11, together with the base plate 15, is lifted to the initial height.

[0068] Fire extinguishing cover 11 reset (s8): Under the action of the first horizontal power component, the fire extinguishing cover 11, together with the base plate 15, is reset to the initial position.

[0069] This embodiment, through the above-described structure and workflow, achieves integrated operations for rapid containment of a burning electric vehicle, efficient flame suppression and heat dissipation, vehicle lifting, closed-loop wastewater recycling, and on-site cleaning, effectively solving the problems mentioned in the background art, such as difficulty in extinguishing fires, high risk of thermal runaway, and difficulty in treating polluting waste liquid.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
