Detailed Implementation

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] like Figure 1-2As shown, a small vehicle-mounted van-type diesel generator power station includes a van 1. Inside the van 1 are installed a generator set, fuel tank, inverter, control box, and electrical junction box. The generator set includes a diesel engine, a rare-earth permanent magnet inverter generator, and a base. A starting battery connected to the generator set's circuitry is also installed inside the van 1. An observation window 11 for observing the control box status is located at the front of the van 1. Air inlets 12 are located at both the front and rear of the van 1, and an exhaust vent 13 is located on one side of the van 1. The air inlets 12 and exhaust vent 13 are used for airflow within the van 1. The air inlets 12, located at the front and rear of the van 1, allow for air circulation, while the exhaust vent 13, located on the side of the van 1, forms an airflow channel, promoting the circulation of hot air within the van 1 and achieving heat dissipation. A cooling fan can be installed inside the van 1 corresponding to the location of the exhaust vent 13. The cooling fan increases the airflow rate and improves the efficiency of hot air exhaust from the exhaust vent, enhancing the heat dissipation effect and allowing the diesel generator power station to operate for extended periods at high temperatures. A cooling fan is also installed on the other side of the van 1. The unit has an exhaust pipe 2 connected to the exhaust port of the diesel engine. The exhaust pipe 2 is used to discharge the exhaust gas generated when the diesel engine starts. The side wall of the compartment 1 is equipped with multiple maintenance doors 14 to facilitate quick maintenance of important components such as the air filter and the diesel engine. A muffler is installed on the top of the generator set near the exhaust pipe 2 on the inner top of the compartment 1. Vibration dampers are installed at the bottom of the compartment 1. The compartment 1 houses a 3kW generator set, fuel tank, inverter, frame, starting battery, integrated control system control box with control panel, muffler, four vibration dampers, and electrical junction box. The noise level of the entire compartment-type generator power station is low, at 70dB. The starting battery can be a lithium battery and is installed on the lower left side of the frame. It is mainly used in low-temperature environments, where the diesel engine temperature drops and it is difficult to start. The starting battery can provide backup power for the diesel engine to start in low temperatures, ensuring that the engine can work normally in environments with temperatures as low as -40℃ and altitudes of 5000m.

[0015] The inverter is installed at the lower right end of the frame and is used for AC to DC conversion. The oil tank is an independent tank installed on the top of the frame. The oil tank is equipped with an oil drain port, an oil inlet port, a manual oil filling port, and a level sensor. The control box is installed on the right side of the frame and has a panel and related component mounting beams. The control box panel has an intelligent controller, various operation switches, buttons, and knobs. When the observation window 11 is closed, the information on the control box panel can be observed. When the observation window 11 is open, it is convenient for the operator to operate the control box. The muffler is installed on the top of the frame to reduce the exhaust noise of the engine. The vibration damper is installed at the bottom of the unit to reduce the vibration of the diesel engine during operation. The adapter box is installed on the lower right side of the body and its function is to facilitate power output and grounding interface.

[0016] like Figure 1-2As shown, a maintenance cover 16 is provided on the top of the compartment 1. Multiple latches 161 are provided between the front side of the maintenance cover 16 and the front side of the compartment 1, and between the rear side of the maintenance cover 16 and the rear side of the compartment 1. The maintenance cover 16 is provided on the top of the compartment 1, and maintenance doors 14 are provided on the front, back, left and right sides. The bottom is designed with a lifting hole for easy lifting. The connection between the maintenance cover 16 and the top of the compartment 1 is provided with a sealing structure. The maintenance cover 16 is located on the top of the compartment 1, which serves to prevent rain and water. The maintenance cover 16 completely covers the top of the compartment 1, so as to open the entire compartment 1 and maintain and replace all the internal parts. The latches 161 fix the maintenance cover 16 to the compartment 1, enhance the sealing and reliably lock the maintenance cover 16 to the compartment 1, preventing the maintenance cover 16 from falling off the compartment 1 due to vibration.

[0017] like Figure 3As shown, the exhaust pipe 2, located inside the compartment 1, has a connecting pipe 21 that connects to the exhaust port of the diesel engine. One end of the connecting pipe 21 is connected to the exhaust port of the diesel engine, and the other end is connected to the exhaust pipe 2. An S-shaped branch pipe 22 is laid on the inner wall of the compartment 1 near the diesel engine. This branch pipe 22, bent in an S-shape, is laid on and fixed to one side of the inner wall of the compartment 1. It can transport the flue gas generated during diesel engine startup, allowing the temperature inside the compartment 1 to be increased by the warmer flue gas in low-temperature environments, thereby increasing the preheating speed of the diesel engine and avoiding... The diesel engine, which is slow to preheat at low temperatures, stops again after starting, maintaining the internal temperature of the compartment 1 in a low-temperature environment. One end of the branch pipe 22 has an air inlet 221 connected to the side wall of the connecting pipe 21, and the other end has an air outlet 222 connected to the connecting pipe 21, located between the air inlet 221 and the exhaust pipe 2. After entering through the air inlet 221 of the branch pipe 22, the flue gas flows along the branch pipe 22 and is then returned to the connecting pipe 21 through the air outlet 222, extending the residence time of the flue gas in the compartment 1, raising the temperature inside the compartment 1, and then discharging from the connecting pipe 21 towards the exhaust pipe 2, thus achieving circulation. The branch pipe 22 has a first control valve 223 at its inlet 221 and a second control valve 224 at its outlet 222. A third control valve 211 is located on the connecting pipe 21 between the inlet 221 and outlet 222 of the branch pipe 22. All three valves (first, second, and third) are existing technologies and can control the opening and closing of the inlet 221 and outlet 222 of the branch pipe 22 and the connecting pipe 21, respectively. When the generator power station is in a low-temperature environment, the third control valve 211 can be closed. The flue gas cannot be directly discharged to the exhaust pipe 2 through the connecting pipe 21. The first control valve 223 and the second control valve 224 are both open, so that after the flue gas enters one end of the connecting pipe 21, it enters from the air inlet 221 of the branch pipe 22 and is discharged from the air outlet 222 to the other end of the connecting pipe, and then is discharged from the exhaust pipe 2. When the generator power station is not in a low temperature environment, the third control valve 211 is opened and the first control valve 223 and the second control valve 224 are closed, so that the flue gas is directly discharged from the connecting pipe 21 to the exhaust pipe 2, avoiding the flue gas from staying in the compartment 1 for too long and causing the internal temperature of the compartment 1 to be too high.

[0018] like Figure 3-4As shown, an annular protrusion 23 is provided at the connection between the exhaust pipe 2 and the body 1. An annular cavity 231 is provided inside the annular protrusion 23. Multiple air holes 232 communicating with the inner side of the annular cavity 231 are provided inside the annular cavity 231. The air holes 232 are inclined towards the air outlet at the outer end of the exhaust pipe 2. An air pump 15 is provided on the inner wall of the body 1. An air passage 17 connecting the air pump 15 and the annular cavity 231 is provided on the side wall of the body 1. When the flue gas flows from the connecting pipe 21 to the exhaust pipe 2 and is discharged, the air pump 15 is activated. The air pump 15 delivers gas to the ventilation channel 17, and the gas is delivered from the ventilation channel 17 to the annular cavity 231. The gas is then discharged from each air hole 232 through the annular cavity 231, creating a negative pressure environment inside the exhaust pipe 2 section. This improves the exhaust efficiency of the diesel engine, reduces the exhaust pressure, and makes the diesel engine start more smoothly, reducing vibration and noise. At the same time, during the exhaust process, the airflow can carry away some of the carbon deposits attached to the inner wall of the exhaust pipe 2, further improving the exhaust efficiency.

[0019] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
