[0019] Emergency power vehicles, as core equipment in the field of mobile power supply, play an irreplaceable role in scenarios such as ground emergency power supply, disaster relief, and temporary power supply. However, in the design and application of traditional emergency power vehicles, especially in enclosed environments such as underground parking garages, exhaust pollution problems are becoming increasingly prominent. Diesel power supply equipment is the core power source of traditional power vehicles, but it generates a large amount of exhaust gas during operation, mainly containing harmful components such as carbon monoxide, nitrogen oxides, and hydrocarbons. In poorly ventilated underground spaces, these exhaust gases easily accumulate, causing a rapid increase in carbon monoxide concentration, which poses a serious threat to the health of personnel. In addition, toxic gases in the exhaust gas can cause varying degrees of environmental pollution, affecting indoor air quality and further increasing safety hazards. More importantly, when conducting emergency rescues in underground spaces, personnel often need to complete their work in a short time. The accumulation and increased concentration of exhaust gases not only affect operational efficiency but may also lead to dangerous situations such as fainting during emergency rescues.

[0020] To address the aforementioned technical problems, this application provides an emergency power supply low-voltage power vehicle.

[0021] In one embodiment of this application, please refer to Figure 1 and Figure 2 The emergency power supply low-voltage vehicle includes a frame 1, power supply equipment 2, a sealed chamber 3, and an exhaust gas treatment device 4. The sealed chamber 3 is sealed to the frame 1, and the power supply equipment 2 is located inside the sealed chamber 3. The exhaust gas treatment device 4 includes an exhaust gas processor 41, a urea tank 42, and an exhaust duct 43. The exhaust duct 43 is located outside the sealed chamber 3 and communicates with the interior of the sealed chamber 3. The urea tank 42 is located on the frame 1, and its injection port is connected to the exhaust gas processor 41.

The air inlet of the exhaust gas processor 41 is connected to the power supply equipment 2, and the air outlet of the exhaust gas processor 41 is connected to the exhaust duct 43. Specifically, the exhaust gas discharged from the power supply equipment 2 enters the exhaust gas processor 41, and the urea in the urea tank 42 is injected into the exhaust gas processor 41 through the injection port, where it reacts chemically with the exhaust gas in the exhaust gas processor 41, thereby purifying the exhaust gas. The treated exhaust gas is then discharged into the external environment through the exhaust duct 43, thus achieving compliant exhaust gas emissions and being green and environmentally friendly.

[0022] The technical solution of this application uses a sealed chamber 3 to install the power supply equipment 2 in a sealed manner, and through the cooperation of the exhaust gas processor 41, the urea tank 42 and the exhaust channel 43, it can purify the exhaust gas generated by the operation of the power supply equipment 2, which is conducive to meeting the environmental protection and safety requirements of enclosed scenarios such as underground spaces, and realizing precise adaptation of emergency power supply in multiple scenarios.

The first partition plate 32, the second partition plate 33, and the inner wall of the carriage 31 enclose the sealed chamber 3. An exhaust duct 43 passes through the first partition plate 32 and communicates with the sealed chamber 3. This embodiment, by forming a sealed chamber 3 through the first partition plate 32, the second partition plate 33, and the inner wall of the carriage 31, and by having the exhaust duct 43 pass through the first partition plate 32 and communicate with the sealed chamber 3, can achieve sealed isolation of the power supply equipment 2 and directional exhaust of exhaust gas, which helps to avoid exhaust gas leakage and accumulation and ensures operational safety in enclosed scenarios such as underground spaces.

Together with heat dissipation components, it can solve the problem of heat accumulation in a compact space and ensure the stable operation of the unit for a long time.

[0026] In one implementation, please refer to Figure 1 and Figure 4The power supply equipment 2 includes a generator 21, an engine 22, and a rectifier converter 23. The input end of the rectifier converter 23 is electrically connected to the output end of the generator 21, and the output end of the rectifier converter 23 is electrically connected to the electrical control box 8 outside the sealed chamber 3. The input shaft of the generator 21 is drive-connected to the output shaft of the engine 22. The exhaust pipe of the generator 21 is connected to the air intake of the exhaust gas processor 41, and the engine 22 is located near the air intake channel 5. This embodiment achieves precise electrical connection between the generator 21 and the electrical control box 8 through the rectifier converter 23. Furthermore, the connection between the generator 21's exhaust pipe and the exhaust gas processor 41, and the proximity of the engine 22 to the air intake channel 5, enable efficient energy conversion, targeted exhaust gas treatment, and rapid heat dissipation of the engine 22. This improves power supply stability and environmental friendliness, and is suitable for emergency power supply in various scenarios.

[0027] In one implementation, please refer to Figure 1 and Figure 4 The low-voltage power supply vehicle also includes a silent electric fan 6, which is installed in a sealed chamber 3 and located between the air intake duct 5 and the engine 22. This embodiment, by installing a silent electric fan 6 between the air intake duct 5 and the engine 22, can reduce operating noise while ensuring the heat dissipation effect of the engine 22, making it suitable for noise-sensitive environments such as underground parking garages and shopping malls, and improving the comfort of the working environment.

[0028] In one implementation, please refer to Figure 1 and Figure 4 The low-voltage power supply vehicle also includes a radiator 7, which is placed inside a sealed chamber 3 and located between the air intake duct 5 and the engine 22.

[0029] In one embodiment, the height of the low-voltage power supply vehicle is h, where 2150mm ≤ h ≤ 2200mm. This embodiment, by controlling the height of the low-voltage power supply vehicle between 2150mm and 2200mm, can accurately adapt to the height restrictions of underground parking garages, which helps to solve the pain point that traditional power supply vehicles of the same power range cannot enter underground parking garages, and enables rapid deployment in underground scenarios.

[0030] In one embodiment, the width of the low-voltage power supply vehicle is L, where L ≤ 2100mm. This embodiment, by controlling the width of the low-voltage power supply vehicle to within 2100mm, can adapt to the passage requirements of narrow passages and small turning radii in underground parking garages, which is beneficial to improving the vehicle's mobility in confined spaces and ensuring flexible deployment in multiple scenarios.

[0031] In one embodiment, the weight of the low-voltage power supply vehicle is G, where G < 7.3t. This embodiment, by controlling the weight of the low-voltage power supply vehicle to within 7.3t, can meet the load-bearing restrictions of the underground parking garage, which helps to avoid safety hazards caused by the vehicle exceeding the site's load-bearing standards and improves the safety of operations in restricted environments.

[0032] In one specific embodiment, please refer to Figures 1 to 6 The low-voltage power supply vehicle frame 1 adopts a lightweight design, with a curb weight controlled within 7.3t. Its external dimensions are within 6000mm in length, 2100mm in width, and 2150~2200mm in height, precisely adapting to the height, width, weight, and passage requirements of most underground parking garages. The vehicle body 31 serves as the main body of the sealed chamber 3, with its side panels sealed to the frame 1 and its detachable top cover detachably sealed to the side panels. The vehicle body 31 is equipped with a first partition plate 32 and a second partition plate 33, which are spaced apart along the axial direction of the vehicle body 31 and sealed to the inner side wall of the vehicle body 31, forming an independent sealed chamber 3 for installing the core power supply unit. The sealed chamber 3 houses a 255kW locomotive power supply unit 2, which is integrated with a 201kW locomotive engine 22, a 201kW locomotive generator 21, a rectifier converter 23, an engine 22 radiator 7, and a silent electric fan 6. The engine 22 is located near the air intake duct 5 that passes through the second partition plate 33. The radiator 7 and the silent electric fan 6 are arranged sequentially between the air intake duct 5 and the engine 22 to form a directional cooling airflow. The exhaust pipe of the generator 21 is connected to the air intake of the exhaust gas processor 41. The exhaust gas processor 41 is fixed in the sealed chamber 3. The unit urea tank 42 is connected to the exhaust gas processor 41 through the injection port. The exhaust duct 43 that passes through the first partition plate 32 is connected to the exhaust gas processor 41 to achieve directional exhaust gas emission. The exterior of the carriage 31 is equipped with a generator oil tank, an electrical control box 8, a cable reel, a hydraulic power control unit box, and an input / output quick interface box. The carriage 31 has a skirt door, a side door, and an electrical control box 8 door on its side. The rear of the carriage 31 has a rear door. The top is equipped with a ladder for easy operation and maintenance from multiple angles. The antifreeze filler is located corresponding to the engine 22 radiator 7 to ensure convenient maintenance of the cooling system.

[0033] The operator drives the power supply vehicle into the target area (underground garage or ground area), and adjusts the vehicle's parking position using the hydraulic power control unit box to ensure stability. The operator opens the side door of the vehicle compartment 31 to check for oil leaks, insufficient oil, and low antifreeze in the power supply equipment 2. The operator also checks the generator's fuel tank level gauge and adds diesel fuel to the appropriate capacity. If working in an underground garage, the operator ensures that the air intake duct 5 and exhaust duct 43 are unobstructed to ensure proper ventilation. The operator then opens the rear door of the vehicle compartment 31, removes the cable reel, and unloads the appropriate length of power cable. Using the quick-connect interface of the input / output quick-connect box, the operator quickly connects the cable to the electrical equipment for seamless connection. Next, the operator opens the electrical control box 8 in the vehicle compartment 31 and operates the control switch to start the power supply equipment 2. The power generated by the engine 22 drives the generator 21, converting mechanical energy into electrical energy. This electrical energy is then rectified and regulated by the rectifier converter 23 before being transmitted to the electrical control box 8, providing a stable low-voltage power supply to the electrical equipment. The exhaust gas generated by the power supply equipment 2 is introduced into the exhaust gas processor 41 through the exhaust pipe. The urea solution in the unit's urea tank 42 is sprayed into the exhaust gas processor 41 through the injection port, where it reacts chemically with the harmful components in the exhaust gas. The purified and compliant exhaust gas is then discharged in a directed manner through the exhaust duct 43, preventing the accumulation of exhaust gas in the underground space. The silent electric fan 6, combined with the sealed design of the carriage 31, significantly reduces operating noise, making it suitable for noise-sensitive environments. After the power demand is met, the power supply equipment 2 is shut off through the electrical control box 8, the cable is retrieved and stored in the cable reel, and all operating doors are closed, completing the emergency power supply operation.

[0034] This power supply vehicle can drive directly into underground parking garages, solving the industry pain point that traditional power supply vehicles of the same power range cannot enter underground garages. It is suitable for emergency power supply in enclosed spaces such as underground shopping malls and underground transportation hubs. At the same time, its exhaust gas treatment system that meets the National VI emission standard, stable 201kW rated power output, and convenient operation design can also meet the power supply needs of conventional scenarios such as ground disaster relief, temporary construction, and large-scale events, achieving the goal of emergency power supply that can be deployed in one place and adapted to multiple scenarios.

[0035] This application aims to protect an emergency power supply low-voltage power vehicle. The technical solution of this application uses a sealed chamber 3 to install the power supply equipment 2 in a sealed manner. Through the cooperation of the exhaust gas processor 41, the urea tank 42 and the exhaust channel 43, the exhaust gas generated by the operation of the power supply equipment 2 can be purified, which is conducive to meeting the environmental protection and safety requirements of enclosed scenarios such as underground spaces, and realizing precise adaptation of emergency power supply in multiple scenarios.
