[0035] Please see Figures 1 to 5This embodiment provides a mobile emergency power supply vehicle with multiple voltage outputs, including a generator set 1, a transformer 2, a power output cabinet, a silencer 4, and a lighting system. The generator set 1 is installed inside the vehicle compartment 7 and has a first power output terminal and a second power output terminal. The generator set 1 is used to output power. The transformer 2 is installed inside the vehicle compartment 7 and has an input terminal and an output terminal. The input terminal is electrically connected to the second power output terminal. The output terminal of the transformer 2 has multiple output interfaces and is used to regulate voltage. The power output cabinet is installed below the vehicle compartment 7 and includes a first power output cabinet 31 and a second power output cabinet 32. The first power output cabinet 31 is electrically connected to the first power output terminal, and the second power output cabinet 32 is electrically connected to the output interfaces on the transformer 2. The power output cabinet is used to provide a connection interface for external power supply. The silencer 4 is installed above the generator set 1 and fixed to the inner wall of the top of the vehicle compartment 7 to reduce the noise generated by the generator set 1. The lighting system is used to provide lighting for emergency operations.
[0036] The carriage 7 has a front end near the locomotive and a rear end away from the locomotive. Generator set 1 is located at the front of carriage 7. The first power output terminal of generator set 1 directly outputs 220V / 380V conventional AC power to meet the needs of ordinary electrical equipment. The second power output terminal is connected to transformer equipment 2, which converts the power output from the second power output terminal into other specifications of current for output, such as 48V DC, 110V AC, and 660V AC. Transformer equipment 2 is located at the rear of carriage 7 and is electrically connected to generator set 1. Through the principle of electromagnetic induction, it converts the voltage output by generator set 1 into a target voltage, such as converting the 380V AC output by generator set 1 into 110V AC or 48V DC to meet the power needs of different scenarios. The power output cabinet is a cabinet used to provide external power connection interfaces. The generator set 1 is located below the carriage 7. The first power output cabinet 31 is electrically connected to the first power output terminal of the generator set 1 to output 220V / 380V conventional voltage. The interface on the first power output cabinet 31 is compatible with ordinary electrical equipment. The second power output cabinet 32 is specifically located below the transformer equipment 2 and is electrically connected to the transformer equipment 2. The second power output cabinet 32 is equipped with DC power output interface and AC power output interface to meet the needs of different electrical equipment. The silencer 4 is composed of sound-absorbing material and a resonant cavity inside the sound-absorbing material. The sound-absorbing material is preferably porous ceramic. When the generator set 1 operates, it generates noise, which is transmitted to the silencer 4. The high-frequency noise is absorbed by the sound-absorbing material, and the low-frequency noise is canceled by the resonant cavity to achieve the effect of reducing the noise inside the carriage 7. The lighting system provides lighting for emergency work to ensure the smooth operation of emergency work at night or in dim environments. Specifically, generator set 1 generates electricity by burning fuel and outputs it from a first power output terminal and a second power output terminal. The power output from the first power output terminal is directly transmitted to the first power output cabinet 31, which supplies power to external electrical equipment that requires the voltage through the interface on the first power output cabinet 31. The power output from the second power output terminal is transmitted to the transformer equipment 2, and after being regulated by the transformer, the voltage of the second power output terminal is regulated to the required voltage and transmitted to the second power output cabinet 32. The second power output cabinet 32 supplies power to external electrical equipment through the interface on the second power output cabinet 32, thereby realizing multi-voltage output to meet different emergency power needs.
[0037] Compared with existing technologies, this embodiment connects the first power output terminal and the second power output terminal of generator set 1 to the first power output cabinet 31 and the transformer equipment 2, respectively. The first power output cabinet 31 outputs 220V / 380V conventional voltage to meet the voltage requirements of ordinary electrical equipment. The power from the second power output terminal is regulated by the transformer equipment 2 and then output to the second power output cabinet 32, realizing the output of multiple voltages and meeting the voltage requirements of different electrical equipment, thus improving the applicability of the mobile emergency power vehicle. The silencer 4 effectively reduces the noise generated by generator set 1 during operation, reduces noise pollution to the surrounding environment and operators, and improves the working environment.
[0038] In this embodiment, the power equipment 2 is a transformer. The power equipment 2 can also be a high-voltage switchgear, a reactive power compensation device, or a UPS energy storage device.
[0039] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the side wall of the carriage 7 is provided with a plurality of ventilation windows 71; the mobile emergency power vehicle also includes a partition 8, which is disposed between the generator set 1 and the transformer equipment 2, and the partition 8 is provided with a plurality of ventilation holes at one end near the bottom of the carriage 7. Ventilation windows 71 are located at the front and rear of the carriage 7. Ventilation windows 71 allow cold air from the outside to enter the carriage 7 while expelling hot air from inside the carriage 7, forming air convection and effectively reducing the temperature inside the carriage 7. The partition 8 is roughly "Z" shaped and is vertically installed between the generator set 1 and the transformer equipment 2, separating the generator set 1 and the transformer equipment 2. It can effectively prevent personnel from accidentally touching or approaching the transformer, avoiding electric shock accidents due to direct contact or insufficient safety distance, ensuring personnel safety, and facilitating equipment maintenance, repair and management. The ventilation holes on the partition 8 ensure air circulation inside the carriage 7, allowing air to enter from the ventilation window 71 at the rear of the carriage 7, pass through the ventilation holes on the partition 8 and exit from the ventilation window 71 at the front of the carriage 7, thereby carrying away the heat generated by the generator set 1 and the transformer equipment 2.
[0040] Please see Figures 1 to 4In this embodiment, the lighting system includes a high-mast lifting light 51, a lifting and adjusting control cabinet 52, and a site lighting light 53. The high-mast lifting light 51 is located at the front end of the vehicle body 7, and the lifting and adjusting control cabinet 52 is located below the vehicle body 7 and electrically connected to the high-mast lifting light 51. The lifting and adjusting control cabinet 52 is used to control the lifting, lowering, and rotation of the high-mast lifting light 51. The site lighting light 53 is installed on the outer wall of the vehicle body 7. The high-mast lifting light 51 achieves height adjustment and illumination direction adjustment through the lifting and adjusting control cabinet 52, and can be flexibly adjusted according to the size of the emergency work site and lighting needs, providing wide-range and long-distance illumination. The site lighting light 53 is installed on the outer wall of the vehicle body 7 and can illuminate a smaller area around the vehicle body 7. The two work together to ensure that emergency operations can be carried out smoothly at night or in low-light environments.
[0041] Please see Figure 1 and Figure 5 In this embodiment, a cable reel 6 is also included. The cable reel 6 is disposed inside the carriage 7 and is used to bundle cables. During emergency power supply, cables are needed to connect the power output cabinet to the electrical equipment. The cable reel 6 can neatly wind up the cables, avoiding messy stacking of cables, facilitating the storage, handling, and use of cables, and also protecting the cables and extending their service life.
[0042] In this embodiment, the mobile emergency power vehicle also includes a charging pile. The second power output cabinet 32 is provided with a DC power output interface and an AC power output interface. The charging pile is electrically connected to both the DC power output interface and the AC power output interface. The charging pile is a device that provides charging services for electric vehicles and other equipment. By connecting to the DC power output interface and the AC power output interface of the second power output cabinet 32, it provides suitable voltage and current for charging electric vehicles, realizing emergency charging of electric vehicles and expanding the application scope of the mobile emergency power vehicle.
[0043] In this embodiment, the top of the carriage 7 is provided with an opening, which is positioned opposite to the generator set 1. When the generator set 1 is operating, it generates a large amount of heat. The opening allows hot air to be quickly expelled from the carriage 7, improving heat dissipation efficiency. Simultaneously, when the generator set 1 needs inspection, maintenance, or replacement of parts, the opening provides a convenient operating passage for personnel, facilitating related work. A cover plate is also provided next to the opening on the top of the carriage 7. This cover plate is detachably connected to the carriage 7 and is used to cover the opening on the top of the carriage 7, preventing rainwater from entering the carriage 7 and affecting the normal operation of the generator set 1.
[0044] In this embodiment, the mobile emergency power supply vehicle also includes multiple ladders, which are installed on the outer side walls of the carriage 7. The ladders provide operators with access to the top of the carriage 7, facilitating the inspection, maintenance, and operation of the equipment on the top of the carriage 7, thus improving the convenience and safety of equipment maintenance.
[0045] Compared with existing technologies, this utility model connects the first power output terminal and the second power output terminal of the generator set 1 to the first power output cabinet 31 and the transformer equipment 2, respectively. The first power output cabinet 31 outputs 220V / 380V conventional voltage to meet the voltage requirements of ordinary electrical equipment. The power from the second power output terminal is regulated by the transformer equipment 2 and then output to the second power output cabinet 32, realizing the output of multiple voltages and meeting the voltage requirements of different electrical equipment, thus improving the applicability of the mobile emergency power vehicle. The silencer 4 effectively reduces the noise generated by the generator set 1 during operation, reducing noise pollution to the surrounding environment and operators, and improving the working environment. The ventilation windows 71 on the side wall of the carriage 7, the ventilation holes on the partition 8, and the opening on the top of the carriage 7 opposite to the generator set 1 form a good air circulation channel, which can dissipate the heat inside the carriage 7 in a timely manner and improve the stability of equipment operation. The lighting system provides sufficient lighting for different emergency operation scenarios, ensuring that emergency operations can be carried out smoothly at night or in low-light environments.
