Emergency power supply vehicle high pressure diesel generator set

Abstract

This invention discloses a high-voltage diesel generator set for an emergency power vehicle, relating to the field of generator set technology. It includes a high-voltage diesel generator body, a controller mounted on the outer surface of the generator body, and a scaling component inside the generator body for adjusting the size of the combustion chamber. When the generator body requires low-load operation, a servo motor is activated, driving a sealing plate upwards via a movable rod. This causes multiple telescopic rods to extend, reducing the space inside the combustion chamber under low-load conditions. This results in highly compressed air within the confined space, enhancing the temperature and pressure at the end of compression. This solves the problem in existing technologies where the combustion space inside the combustion chamber cannot be adjusted according to actual load conditions, leading to resource waste during low-load operation.

Description

Technical Field

[0001] This invention relates to the field of generator set technology, specifically to a high-voltage diesel generator set for emergency power vehicles. Background Technology

[0002] The high-voltage diesel generator set of the emergency power vehicle is the core power equipment of the emergency power vehicle. It is mainly used to provide temporary high-voltage power support for high-voltage electrical equipment and large venues in emergency situations such as power grid failures and power outages. Its core feature is that it is based on a diesel engine to drive the generator and can output high-voltage electrical energy. It has the advantages of fast emergency response, wide power coverage and high reliability. It generates mechanical energy by burning diesel to drive the generator. In short, the high-voltage diesel generator set is the core equipment of the emergency power vehicle to achieve high-voltage, efficient and fast power supply, and plays a key role in the power emergency guarantee system.

[0003] Existing emergency power vehicles, whose core characteristic is "emergency power supply," experience significant load fluctuations and are often under light or overload conditions. Since the combustion space within the combustion chamber cannot be adjusted according to the actual load, the combustion chamber space and compression ratio of existing units are fixed. Their design is mostly based on rated load, making it difficult to consider combustion efficiency under all operating conditions. At low loads, due to the low load and low fuel injection volume, the fixed combustion chamber space leads to an excessively high excess air coefficient, resulting in far more air than fuel. This results in lower temperature and pressure at the end of compression, slower fuel atomization and combustion speed, and a higher risk of incomplete combustion, leading to increased fuel consumption, increased carbon deposits, and wasted resources.

[0004] Therefore, we proposed an emergency power vehicle high-voltage diesel generator set to address the issues mentioned above. Summary of the Invention

[0009] Preferably, a drive motor is fixedly mounted on the outer surface of the support frame by screws, and a drive shaft is fixedly connected to the output end of the drive motor. Servo motors are provided on the inner walls of the plurality of pistons, and rotating rods are fixedly mounted on the output ends of the plurality of servo motors.

[0012] Preferably, the two ends of the drive shaft extend movably to the opposite sides of the support frame, the top ends of the multiple connecting rods are coupled to the bottoms of the multiple pistons, and the outer surfaces of the multiple sealing plates slide against the inner walls of the multiple chambers.

[0013] Preferably, the plurality of helical gears are grouped into sets of three adjacent to each other, and the outer surface of each set of helical gears is meshed with the outer surface of the plurality of worm gears, and the top ends of the plurality of movable rods are rotatably connected to the outer surface of the plurality of movable connectors.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the high-voltage diesel generator body needs to operate under low load, the servo motor is started, and the upward movement of the movable rod drives the sealing plate to move upward, thereby causing multiple telescopic rods to extend. This reduces the space inside the combustion chamber of the high-voltage diesel generator body under low load, allowing the air to be highly compressed in the confined space. Reducing the combustion chamber space can enhance the temperature and pressure at the end of compression, solving the problem in the existing technology where the combustion space inside the combustion chamber cannot be adjusted according to the actual load, which easily leads to resource waste when operating under low load.

[0018] 2. When the high-pressure diesel generator needs to operate under high load, the servo motor is restarted to drive the sealing plate downward, thereby increasing the space of the combustion chamber formed by the sealing plate and the chamber. By increasing the combustion chamber space, knocking caused by excessive pressure can be avoided, protecting engine components, and reducing the generation of nitrogen oxides at high temperatures. This solves the problem in the existing technology that the combustion space in the combustion chamber cannot be adjusted according to the actual load, which can easily shorten the life of the unit.

[0019] 3. When the high-temperature gas from combustion in the chamber is discharged outward through multiple exhaust valves, it first flows into the interior of the guide pipe, and finally enters the interior of the turbocharger through the return pipe. Under the compression of the turbocharger, it enters the intercooler, and finally enters the interior of multiple chambers through multiple intake valves, thus realizing the delivery of high-pressure gas in the chamber. Through the function of the return pipe, the exhaust gas in the combustion chamber of the high-pressure diesel generator is recycled and reused. Attached Figure Description

A connecting pipe 305 is fixedly connected to one end of the drain pipe 304. Multiple chambers... Each chamber 308 has an injector 307 coupled to its top. The outer surfaces of each injector 307 are fixedly connected to a distributor pipe 306. A support frame 309 is fixedly installed near the bottom between the relative inner walls of the high-voltage diesel generator body 1. A drive motor 310 is fixedly installed on the outer surface of the support frame 309 by screws. A drive shaft 311 is fixedly connected to the output end of the drive motor 310. Servo motors 316 are installed on the inner walls of each piston 313. Rotary rods 317 are fixedly installed at the output ends of each servo motor 316.

Two movable rods 322 are fixedly sleeved on the outer surfaces of multiple connecting shafts 320. Multiple movable connecting parts 323 are fixedly fixed to the bottom of multiple sealing plates 315. The outer surface of the oil tank 301 is fixedly connected to the inner wall of the high-voltage diesel generator body 1. The top end of the connecting pipe 303 is fixedly inserted into the interior of the oil tank 301. The top ends of multiple branch pipes 306 are fixedly inserted into the interior of the connecting pipe 305. The two ends of the drive shaft 311 are movably inserted into the opposite outer surfaces of the support frame 309. The top ends of multiple connecting rods 312 are coupled to the bottom of multiple pistons 313. The outer surfaces of multiple sealing plates 315 slide against the inner walls of multiple chambers 308.Multiple helical gears 321 are grouped in sets of three, and the outer surface of each group of helical gears 321 meshes with the outer surfaces of multiple worm gears 318. The top ends of multiple movable rods 322 are rotatably connected to the outer surfaces of multiple movable connectors 323.

[0032] In this embodiment, when using the high-voltage diesel generator set of the emergency power vehicle for emergency power supply, the high-voltage diesel generator body 1 can be moved to the location of the equipment requiring power. The high-voltage diesel generator body 1 generates mechanical energy through diesel combustion, which is then converted into high-voltage electrical energy. Combined with an intelligent control system, it achieves rapid response and stable power supply. During the intake stroke: the drive motor 310 is started, driving the drive shaft 311 to rotate, which in turn drives multiple connecting rods 312 downwards, thereby driving multiple pistons 313 downwards along the interior of multiple chambers 308. This allows outside air to enter the interior of the chambers 308 through multiple intake valves 410. As the drive shaft 311 continues to rotate, it drives multiple connecting rods 312 upwards, thereby driving multiple pistons 313 upwards, compressing the air to a high-pressure, high-temperature state. At this point, the fuel pump 302 can be started, driving the connecting pipe 303 to draw diesel fuel into the fuel tank 301. The diesel fuel then enters the connecting pipe 305 through the drain pipe 304, and finally... The diesel fuel enters through multiple branch pipes 306 into multiple injectors 307. The injector 307 works as follows: it atomizes the diesel fuel and injects it into chamber 308. The diesel fuel ignites spontaneously, and the high-pressure gas generated by combustion pushes piston 313 downwards. Multiple connecting rods 312 convert linear motion into rotational mechanical energy, which is then driven by drive motor 310 to rotate drive shaft 311, pushing piston 313 upwards. This allows exhaust gas to be discharged through multiple exhaust valves 401, completing one cycle. The diesel engine drives generator rotor to rotate, and stator windings cut magnetic lines of force to generate alternating current. An automatic voltage regulator controls the excitation current to ensure stable output voltage. When the high-voltage diesel generator body 1 requires low-load operation, to ensure complete combustion of the diesel fuel injected into chamber 308 by injectors 307, servo motor 316 is first activated, driving rotor 317 to rotate, which in turn drives worm gear 318, which in turn drives multiple helical gears 321, thereby activating multiple movable rods 322 to move upwards. For example... Figure 6As shown, the movable rod 322 consists of two rotatably connected long rods. Its purpose is to facilitate the up-and-down movement of the sealing plate 315. The upward movement of the movable rod 322 drives the sealing plate 315 to move upward, thereby causing multiple telescopic rods 314 to extend. This reduces the combustion space formed between the top of the sealing plate 315 and the chamber 308, thus reducing the space inside the combustion chamber of the high-pressure diesel generator body 1 under low load conditions. This allows the air to be highly compressed in the confined space. Reducing the combustion chamber space can enhance the temperature and pressure at the end of compression, promote complete combustion of fuel, and reduce the increase in fuel consumption and carbon deposits caused by incomplete combustion. This solves the problem in the prior art where the combustion space inside the combustion chamber cannot be adjusted according to the actual load conditions, which can easily lead to resource waste when operating at low load.

[0033] like Figures 1-7 As shown, a drive motor 310 is fixedly mounted on the outer surface of the support frame 309 by screws. The output end of the drive motor 310 is fixedly connected to a drive shaft 311. Servo motors 316 are installed on the inner walls of multiple pistons 313. Rotary rods 317 are fixedly mounted on the output ends of multiple servo motors 316. Worms 318 are fixedly connected to the top of multiple rotating rods 317. Three helical gears 321 are meshed on the outer surfaces of multiple worms 318. Three mounting brackets 319 are fixedly connected to the top of multiple pistons 313. Connecting shafts 320 are movably sleeved between the relative inner walls of multiple mounting brackets 319. Two movable rods 322 are fixedly sleeved on the outer surfaces of multiple connecting shafts 320. Multiple movable connecting parts 323 are fixedly fixed to the bottom of multiple sealing plates 315.

[0034] In this embodiment, when the high-voltage diesel generator body 1 needs to operate under high load, the servo motor 316 can be restarted to drive the rotating rod 317 to rotate, which in turn drives the worm gear 318 to rotate in the opposite direction. This causes multiple helical gears 321 to rotate in the opposite direction, which in turn causes multiple movable rods 322 to rotate downward. This causes the sealing plate 315 to move downward, thereby increasing the space of the combustion chamber formed between the sealing plate 315 and the chamber 308. Under high load, increasing the combustion chamber space can prevent knocking caused by excessive pressure, protect engine components, and reduce the generation of nitrogen oxides at high temperatures. By dynamically adjusting the combustion space inside the combustion chamber, the compression ratio can be actively reduced under high load to control the peak combustion pressure within a safe range and reduce the risk of knocking. Under low load, the compression ratio can be increased to improve diesel combustion efficiency, balance mechanical stress under various operating conditions, and extend the service life of the engine. This solves the problem in the prior art that the combustion space inside the combustion chamber cannot be adjusted according to the actual load, which can easily shorten the life of the unit.

[0035] like Figure 2 and Figure 8As shown, the emergency power vehicle high-voltage diesel generator set includes a high-voltage diesel generator body 1, a controller 2 mounted on the outer surface of the high-voltage diesel generator body 1, and a scaling assembly 3 inside the high-voltage diesel generator body 1 for adjusting the size of the combustion chamber. The scaling assembly 3 includes multiple chambers 308 for diesel combustion, each chamber 308 having a piston 313 slidably connected to it for pressurizing air. The bottom of each piston 313 is rotatably connected to a connecting rod 312 for driving the piston 313 up and down. Four telescopic rods 314 are evenly fixedly mounted near the edge of the top of each piston 313, with four adjacent telescopic rods forming a group. A sealing plate 315 for scaling the volume of the combustion chamber is fixed between the top ends of each group of telescopic rods 314. The high-voltage diesel generator body 1 also includes a circulation assembly 4 for heat recovery and utilization. The circulation assembly 4 includes a turbocharger 406 and multiple exhaust valves 401, with the outer surfaces of the multiple exhaust valves 401 fixedly connected. The system includes a guide pipe 402, the top of which is fixedly connected to a return pipe 403 for diverting hot air. The circulation assembly 4 also includes an intake pipe 404, the outer surface of which is provided with a control valve 405. The bottom of the turbocharger 406 is fixedly connected to an intercooler 407, the bottom of which is fixedly connected to an intake manifold 408. The outer surface of the intake manifold 408 is provided with an intake valve 409. The tops of multiple chambers 308 are all fixedly connected to intake valves 410. The multiple intake valves 410... The top of each of the multiple exhaust valves 401 is fixedly connected to the inside of the multiple chambers 308. The bottom of the intake pipe 404 is fixedly connected to the inside of the return pipe 403. One end of the return pipe 403 is fixedly connected to the inside of the turbocharger 406. The top of each of the multiple input pipes 411 is fixedly connected to the inside of the intake manifold 408. A mounting bracket 5 is fixedly installed on the inner wall of the high-pressure diesel generator body 1. The inner wall of the mounting bracket 5 is fixedly connected to the outer surface of the multiple chambers 308.

[0036] In this embodiment, when the high-temperature gas from combustion in chamber 308 is discharged outward through multiple exhaust valves 401, it first flows into the interior of guide pipe 402, and finally enters the interior of turbocharger 406 through return pipe 403. Turbocharger 406, composed of turbine impeller and turbine housing, receives the high-temperature, high-pressure gas and compresses it before entering intercooler 407. The main function of intercooler 407 is to cool and reduce the temperature of the turbocharged high-temperature air, increasing its density and thus further increasing the effective amount of air entering the combustion chamber. The gas processed by intercooler 407 then passes through the intake... The intake manifold 408 enters the interior of multiple input pipes 411, and finally enters the interior of multiple chambers 308 through multiple intake valves 410, thereby realizing the delivery of high-pressure gas in the chambers 308. Through the function of the return pipe 403, the exhaust gas in the combustion chamber of the high-pressure diesel generator is recovered and reused. In addition, by setting a control valve 405 on the outer surface of the intake pipe 404, its core function is to protect the turbocharger 406 and the engine, alleviate turbo lag, and stabilize the intake system pressure. It is an important protection and regulation device for the turbocharger 406 system, which directly affects the life of the turbocharger, the power response of the engine, and the operational stability.

[0037] The usage and working principle of this device: When using the high-voltage diesel generator set of the emergency power vehicle for emergency power supply, the high-voltage diesel generator body 1 can be moved to the location of the equipment requiring power. The high-voltage diesel generator body 1 generates mechanical energy through diesel combustion, which is then converted into high-voltage electrical energy. Combined with an intelligent control system, it achieves rapid response and stable power supply. Intake stroke: The drive motor 310 is started, driving the drive shaft 311 to rotate, which in turn drives multiple connecting rods 312 to move downward, thereby driving multiple pistons 313 to move downward along the interior of multiple chambers 308. This allows outside air to enter the interior of chambers 308 through multiple intake valves 410. As the drive shaft 311 continues to rotate, it drives multiple connecting rods 312 to move upward, thereby driving... Multiple pistons 313 move upwards, compressing air to a high-pressure, high-temperature state. At this point, the fuel pump 302 is activated, driving the connecting pipe 303 to draw diesel fuel into the fuel tank 301. The diesel fuel then enters the connecting pipe 305 through the guide pipe 304, and finally flows through multiple branch pipes 306 into multiple injectors 307. The injectors 307 atomize the diesel fuel and spray it into the chamber 308. The diesel fuel ignites spontaneously, and the high-pressure gas generated by combustion pushes the pistons 313 downwards. Multiple connecting rods 312 convert the linear motion into rotational mechanical energy, which is then driven by the drive motor 310 to rotate the drive shaft 311, pushing the pistons 313 upwards. This causes the exhaust gas to be discharged through multiple exhaust valves 401, completing one cycle. The generator rotor rotates, and the stator windings cut magnetic field lines to generate alternating current. An automatic voltage regulator controls the excitation current to ensure stable output voltage. When the high-voltage diesel generator body 1 requires low-load operation, to ensure complete combustion of the diesel fuel injected into the chamber 308 by the injector 307, the servo motor 316 is activated, driving the rotating rod 317 to rotate, which in turn drives the worm gear 318 to rotate, thereby rotating multiple helical gears 321. This causes multiple movable rods 322 to move upwards. The upward movement of the movable rods 322 drives the sealing plate 315 to move upwards, which in turn causes multiple telescopic rods 314 to extend. This reduces the combustion space between the top of the sealing plate 315 and the chamber 308, thus reducing the combustion space between the high-voltage diesel generator and the chamber 308. Under low load conditions, the combustion chamber space of the main body 1 shrinks, causing the air to be highly compressed within a confined space. This reduces the combustion chamber space and increases the temperature and pressure at the end of compression. When the high-pressure diesel generator main body 1 needs to operate under high load conditions, the servo motor 316 is restarted, driving the rotary rod 317 to rotate, which in turn drives the worm gear 318 to rotate in the opposite direction. This causes multiple helical gears 321 to rotate in the opposite direction, which in turn causes multiple movable rods 322 to rotate downwards. This causes the sealing plate 315 to move downwards, thereby increasing the space of the combustion chamber formed by the sealing plate 315 and the chamber 308. Under high load conditions, increasing the combustion chamber space can prevent knocking caused by excessive pressure, protect engine components, and reduce the generation of nitrogen oxides at high temperatures.By dynamically adjusting the combustion space within the combustion chamber, the compression ratio can be actively reduced under high loads to control peak combustion pressure within a safe range, reducing the risk of knocking. Under low loads, the compression ratio can be increased to improve diesel combustion efficiency, balance mechanical stress under various operating conditions, and extend engine life. When the high-temperature gas from combustion in chamber 308 is discharged through multiple exhaust valves 401, it first flows into the guide pipe 402, and finally enters the turbocharger 406 through the return pipe 403. Under compression by the turbocharger 406, it enters the intercooler 407. The main function of the intercooler 407 is to cool and reduce the temperature of the high-temperature air after turbocharging, increasing air density and thus further increasing the effective air volume entering the combustion chamber. The gas processed by the intercooler 407 then enters multiple input pipes 411 through the intake manifold 408, and finally enters multiple chambers 308 through multiple intake valves 410.
