[0020] like Figures 1-3 As shown, a road de-icing and snow removal emergency rescue vehicle includes a vehicle chassis 1, a subframe 9, a cargo box 3, a fuel tank 2, a turbofan engine 4, an air intake assembly 5, a fire extinguishing assembly 6, a power supply assembly 7, an engine support frame 8, a hydraulic starting assembly 10, a purging assembly 11, a fuel supply assembly 12, and a control assembly 13.

[0021] 1. Basic load-bearing system The vehicle chassis 1 adopts a heavy-duty truck chassis, which has good load-bearing capacity and off-road performance, and is suitable for various road conditions; it also has good low-temperature starting performance and is suitable for extremely cold environments.

[0022] The subframe is fixedly installed on the upper part of the vehicle chassis 1, serving as the integrated load-bearing platform for the entire vehicle and providing the installation foundation for all snow removal equipment.

[0023] like Figure 4As shown, the subframe 9 includes a subbeam and side frames. The subbeam is welded from a subbeam base plate, air intake plate, main beam, cargo box mounting opening, corridor plate, engine and bracket mounting opening, exhaust pipe opening, crossbeam, side stiffener plates, and reinforcing plates, and features high strength and rigidity. The subbeam is connected to the vehicle chassis 1 by two different types of fixing bolts: one type is vertical bolts, used to limit the vertical displacement of the subframe 9 under impact loads; the other type is horizontal bolts, used to limit the front-rear displacement of the subframe 9 during vehicle acceleration and braking.

[0024] A 14mm thick rubber vibration damping pad is installed between the sub-beam and the vehicle chassis 1, which can effectively attenuate the vibration of the turbofan engine 4 and the road surface, reduce noise, and protect the equipment and passengers.

[0025] The side frame integrates a power supply box, oil tank, side crash barriers, side crash auxiliary supports, toolbox, mudguards, control cabinet, and rear crash barrier, realizing the centralized arrangement of auxiliary equipment and improving space utilization.

[0026] 2. Carriage System The carriage 3 is fixed to the vehicle chassis 1 and subframe 9 by mounting base bolts, and is used to house and protect all snow removal core equipment.

[0027] like Figure 5 As shown, the carriage 3 includes a main frame, folding doors, hydraulic cylinders, air intake windows, louvered doors, ladders, pedestrian openings, lighting, warning lights, and guide lights.

[0028] The main frame of the cargo box consists of a front cargo box roof, a rear cargo box roof, a front cargo box wall, a main support frame, a rear cargo box wall, shock absorbers, and a support structure. The front and rear cargo box roofs are welded to the front cargo box wall, the main support frame, and the rear cargo box wall, respectively, forming the main frame of the cargo box. Shock absorbers are installed on both sides of the bottom of the main frame of the cargo box. The shock absorbers are connected to the support frame, which is fixed to the main beam of the vehicle chassis 1, further damping vibrations.

[0029] The folding doors on both sides are hinged to the main frame of the cargo box, and are opened and closed by hydraulic cylinders. One end of the hydraulic cylinder is connected to the mounting side wall of the folding door, and the other end is connected to the mounting plate of the main frame of the cargo box. A lever-type door lock is installed below the folding doors to ensure sealing and security when closed. Air intake windows are provided on the folding doors, and louvered doors are installed on the rear wall of the cargo box, ensuring air intake for engine operation while preventing rain, snow, leaves, and other impurities from entering the cargo box.

[0030] A ladder is installed at the rear of carriage 3. The ladder includes handrails, a long ladder, a short ladder, and a fixed base, facilitating maintenance personnel to climb to the roof. A pedestrian opening is provided on the roof, with welded plates along its edges. The opening cover is bolted to the welded plates, and a rubber sealing ring is installed in the middle for waterproofing. Handrails are also provided on the roof to ensure the safety of maintenance personnel when walking on it.

[0031] The interior of carriage 3 is also equipped with a fire extinguishing system 6, including a smoke detector, a temperature sensor, and a suspended fire extinguisher, all electrically connected to the control system 13. When a fire is detected inside carriage 3, the system automatically triggers the suspended fire extinguisher to spray extinguishing agent, achieving automatic fire suppression. A heat insulation mechanism is installed between the fuel tank 2 and the purging assembly 11 to prevent the high-temperature pipe walls from igniting the fuel.

[0032] 3. Power System like Figure 6 As shown, the turbofan engine 4 is the core power unit of the vehicle. It adopts the Yake series of domestically modified turbofan engines, retaining the core compressor, turbine, combustion chamber, mixer and transmission system. Unnecessary components such as aviation hydraulic oil pump, alternator, and thrust reverser have been removed, and vehicle-compatible intake, exhaust, fuel supply and starting systems have been added.

[0033] The turbofan engine 4 is obliquely fixed to the subframe 9 via an engine support frame 8. The engine support frame 8 and the subframe 9 are detachably connected by bolts. The engine can be removed as a whole by unscrewing the bolts, enabling quick maintenance and replacement. The oblique arrangement reduces airflow resistance, avoids the center of gravity shift caused by the upright placement of the engine, optimizes the front and rear axle load distribution, improves vehicle driving stability, and expands the coverage area of ​​the hot air operation.

[0034] The turbofan engine 4 has an exhaust outlet temperature of 100-300℃, an exhaust ground temperature of 60-100℃, a displacement of 30 kg / s, an initial overhaul life of ≥5000h, and a total life of ≥21000h. The turbofan engine 4 incorporates an over-control protection device and an anti-surge regulation system: the over-control protection device includes a turbine afterburner exhaust temperature limiter and a high-pressure compressor afterburner air pressure limiter, which can prevent key parameters from exceeding specified values; the anti-surge regulation system employs dual-duct, bleed valve, and compressor guide vane adjustment technology to effectively prevent compressor surge and ensure stable engine operation.

[0035] 4. Purging System The blowing assembly 11 is the component that directly performs snow removal operations. It includes the main blowing assembly 11-1 and the auxiliary blowing assembly 11-2, both of which are fixed to the underside of the vehicle chassis 1 by a limiting and fixing bracket.

[0036] The main purging unit 11-1 draws air from the turbofan engine 4, which extends through a pipe to the underside of the vehicle chassis 1 and blows air onto the right side of the vehicle, covering a road surface area 15-25 meters wide on the right side, equivalent to 3-5 lanes. A wire rope vibration isolator is installed between the main purging unit 11-1 and the subframe 9 to effectively attenuate the impact of engine vibration on the pipe.

[0037] The auxiliary snow blower unit 11-2 extends from the opening at the rear main nozzle of the turbofan engine 4, downwards to below the vehicle chassis 1 and towards the front of the vehicle, connecting with the cross air duct opening. It is used to blow away snow in front of the vehicle and under the vehicle body, eliminating the blind spots of traditional snow blowers. The auxiliary snow blower unit 11-2 is flexibly connected to the main snow blower unit 11-1 via a corrugated pipe to further absorb vibration and prevent pipe cracking.

[0038] 5. Fuel System The fuel system consists of a fuel tank 2 and a fuel supply assembly 12, which provides a stable fuel supply to the turbofan engine 4.

[0039] like Figure 7 As shown, fuel tank 2 is an integrated welded structure designed for wave protection, explosion prevention, and vibration damping. It mainly includes a top plate, left side plate, right side plate, front sealing plate, rear sealing plate, bottom plate, filler neck, manhole cover, anti-static grounding strap, drain outlet, lifting ring, level gauge, and spare filler neck. The fuel tank 2 is internally equipped with transverse and longitudinal wave-damping baffles to suppress the surge energy of fuel during vehicle operation and prevent center of gravity shift. The top manhole cover assembly integrates a breather valve, which adaptively adjusts the internal pressure to prevent the tank from bursting due to temperature changes, thus achieving explosion-proof functionality.

[0040] The fuel tank 2 is flexibly connected to the subframe via a support assembly, which includes an upper support plate, an upper stiffening plate, a high-damping vibration damping pad, a lower stiffening plate, connecting bolts, a lower support plate, and a large washer. The upper support plate is welded to the bottom plate of the fuel tank 2, and the lower support plate is welded to the subframe 9. The two are flexibly connected by the high-damping vibration damping pad and connecting bolts, which can effectively attenuate engine and road vibrations and achieve vibration damping function. An anti-static grounding strip is provided on the side of the fuel tank 2 to eliminate static electricity accumulation and ensure safety. A level gauge is also installed on the fuel tank 2 and connected to the control component 13, which can display the remaining fuel level in real time in the driver's cab.

[0041] The fuel supply assembly 12 includes a fuel pump, a Y-type filter, a solenoid valve, and a fuel pipeline. One end of the pipeline is connected to the fuel tank 2, and the other end is connected to the fuel inlet of the turbofan engine 4, thereby achieving fuel filtration and delivery.

[0042] 6. Hydraulic starting system like Figure 8As shown, the hydraulic starting assembly 10 is used to start the turbofan engine 4 and open and close the folding door of the carriage 3. It mainly includes a hydraulic pump, a hydraulic valve group, a hydraulic oil tank, a hydraulic motor, hydraulic hoses and a manual emergency pump.

[0043] The hydraulic pump receives power from the PTO interface on the transmission of the vehicle chassis 1, which transmits power to the hydraulic pump via a drive shaft. The hydraulic valve assembly integrates two independent control circuits: one connects to the starter motor of the turbofan engine 4 via ports A1 and B1 to start the turbofan engine 4; the other connects to the hydraulic cylinder of the cargo compartment 3 via ports A2 and B2 to open and close the folding doors. Return oil from both circuits flows back to the hydraulic oil tank via port T.

[0044] The working principle of the hydraulic starting assembly 10 is as follows: the hydraulic pump rotates to deliver hydraulic oil to the hydraulic motor, the hydraulic motor drives the clutch assembly to drive the turbofan engine 4; when the speed of the turbofan engine 4 reaches a certain speed, the clutch assembly automatically disengages from the torque transmission of the hydraulic motor, and at the same time shuts off the chassis power take-off, and the hydraulic starting system stops working.

[0045] The manual emergency pump is connected in parallel with the folding door control circuit. When the vehicle loses power, the folding door can be opened by manually pressing the emergency pump to enable emergency maintenance.

[0046] 7. Electrical and Control Systems The power supply assembly 7 consists of two independent power supply systems. The first system supplies power to the turbofan engine 4 and its associated ignition and fuel supply equipment. The second system supplies power to the control assembly 13, the health management system 15, the video monitoring system 16, and other control components. The independent operation of these two systems prevents a single failure from causing a complete vehicle breakdown, thus improving system reliability. The power supply assembly 7 is bolted to the side frame of the subframe 9.

[0047] The control system is centered on the control component 13 and is electrically connected to the touch screen 14, the health management system 15 and the video monitoring system 16. All control units are integrated in the cab, allowing operators to complete all operations without leaving the vehicle.

[0048] The touchscreen 14 features high resolution, high sensitivity, and excellent anti-interference capabilities, providing a clear and intuitive operating interface. It enables functions such as one-button engine start / stop, snow removal gear adjustment, and electronic virtual instrument display. Operators can adjust the engine's operating status according to the snow thickness on the road surface: a lower gear for light snow to save fuel, and a higher gear for heavy snow to ensure efficient snow removal.

[0049] The health management system 15 includes an onboard system host, a health management monitoring screen, and a wireless signal router. It can acquire real-time operating status data of the snowplow and engine, providing functions such as status monitoring and alarm, fault diagnosis and prediction, lifespan monitoring and early warning, and maintenance optimization decision-making. The snowplow's health information can be transmitted to a remote operation and maintenance center via the wireless signal router. Remote experts can then download the analysis and processing results back to the onboard system, providing operators with immediate decision support.

[0050] The video surveillance system 16 includes multiple surveillance cameras installed on the roof beam inside the carriage 3 and display equipment in the driver's cab. Operators can view the operating status of key components such as the engine and fuel tank in real time and perform routine inspections without opening the door.

[0051] Working principle: The vehicle is driven to the snow-covered road work area. The operator starts the aircraft engine with one button on the touch screen 14 in the cab. The power transmission route is from the power take-off unit of the transmission in the vehicle chassis 1 to the hydraulic starting assembly 10. The hydraulic motor in the hydraulic assembly 10 drives the turbofan engine 4 to ignite and start. Outside air enters the intake assembly 5 through the air intake window and louver door of the compartment 3. After being filtered, it enters the turbofan engine 4, where it is compressed, burned, and expanded to produce high-speed, high-temperature gas.

[0052] The gas enters the purging assembly 11 in two streams: one stream enters the main purging unit 11-1, spraying high-speed hot air towards the right side of the vehicle to blow the snow on the right side of the road to the roadside; the other stream enters the auxiliary purging unit 11-2, spraying hot air towards the front of the vehicle to clear the snow in front of the vehicle and under the vehicle body. The vehicle moves forward at a constant speed, and the hot air blows away the loose snow while melting the thin ice close to the road surface, achieving thorough snow removal without blind spots.

[0053] During operation, the health management system 15 monitors engine parameters such as temperature, speed, oil pressure, and vibration in real time. In case of abnormalities such as overheating, overspeeding, or excessive vibration, the system automatically reduces the engine throttle to idle or shuts off the fuel line to stop the vehicle, ensuring equipment safety. The video monitoring system 16 monitors the interior of the vehicle compartment in real time, and the fire extinguishing components 6 are on standby. After the operation is completed, the engine is shut off via the touchscreen 14, and the vehicle leaves the work area.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
