[0003] The ultra-quiet diesel generator set is a device that uses diesel as fuel and converts mechanical energy into electrical energy by driving a generator with a diesel engine. The diesel engine in the ultra-quiet diesel generator set completes energy conversion through four strokes: intake, compression, combustion and exhaust. During the intake stroke, fresh air enters the cylinder; during the compression stroke, the air is compressed, and the temperature and pressure increase; then the injector sprays mist diesel into the combustion chamber, which mixes with the high-temperature and high-pressure air and burns itself, generating high pressure to push the piston and drive the crankshaft to rotate. The crankshaft of the diesel engine is connected to the generator rotor. The generator uses the principle of electromagnetic induction to convert rotational mechanical energy into electrical energy.

[0004] However, traditional ultra-quiet diesel generator sets will produce large mechanical vibrations and combustion noise during operation, seriously affecting the quality of life and work efficiency of people around them. Although various measures have been taken to try to overcome this problem, the actual application effect is not ideal due to the lack of coordination and linkage mechanism between the various processing links and the focus on improvement in a single dimension.

The heat exchange pipe assembly 31 transfers heat to the preheating pipe assembly 22 through the heat exchange fluid medium 4 to preheat the intake pipe 21. The heat exchange fluid medium 4 can not only realize the transfer of heat energy to improve the combustion efficiency of the diesel engine 2, but also absorb the vibration generated by the device during operation to reduce noise.

[0037] In this embodiment, the heat exchange fluid medium 4 may be water.

[0038] Please continue reading Figure 2 The preheating tube assembly 22 includes: a preheating tube 221 and a rock wool sleeve 222.

[0041] In this embodiment, the filter unit 232 may be a diesel particulate filter.

[0042] See also Figure 1 , a generator set 3 is arranged on the base 1 and is located on the other side above the receiving groove 11, and a rotor of the generator set 3 is connected to a driving shaft of the diesel engine 2; See also Figure 3 The generator set 3 includes: a generator base 32 and a generator 33. The generator base 32 is fixedly assembled on the machine base 1. The generator base 32 is fixedly assembled below the generator 33. The generator base 32 is fixedly assembled on the machine base 1. A spiral groove 331 is provided on the outside of the generator 33. The heat exchange tube assembly 31 is sleeved on the outside of the generator 33 and assembled on the groove 331. A spiral adapting groove 321 is provided on the upper surface of the generator base 32. The heat exchange tube assembly 31 is assembled on the adapting groove 321 on the side close to the generator base 32. By setting the spiral groove 331, it can be adapted to the heat exchange tube assembly 31 which is also spiral, and at the same time, the heat exchange efficiency between the heat exchange tube 311 and the generator 33 can be increased.

[0043] Please refer to Figure 3 and Figure 4 The heat exchange tube assembly 31 includes: a heat exchange tube 311 and a heat dissipation silicone pad 312. The heat exchange tube 311 is spirally shaped. The heat exchange tube 311 is sleeved on the groove 331 of the generator 33 and extends along the length direction of the generator 33.

One side of the heat dissipation silicone pad 312 is connected to one side of the heat exchange tube 311, and the other side is assembled on the adapter groove 321 and matches the shape of the adapter groove 321. Through the spiral heat exchange tube 311, the heat of the generator 33 can be absorbed to a great extent through the heat exchange fluid medium 4 and transferred to the preheating tube assembly 22, thereby improving the heat dissipation effect of the generator 33 while preheating the air entering the diesel engine 2.

[0044] In this embodiment, the heat exchange tube 311 is a copper tubular component.

The weighted ball 3132 is mounted on the other end of the metal elastic strip 3131. By setting the metal elastic strip 3131 and fixing it to one side of the heat exchange tube 311, when the device vibrates, it can drive the metal elastic strip 3131 to vibrate, thereby reducing part of the vibration generated by the generator 33 during operation to reduce noise.

[0046] In this embodiment, the metal elastic strip 3131 is a strip-shaped copper strip.

[0047] Example 2 The basic structure of Example 2 is the same as that of Example 1, except that: See also Figure 6 The vibration-damping fluid medium 12 is a granular fluid medium. A notch 14 connected to the accommodating groove 11 is provided on one side of the base 1. A blocking component 15 is provided in the notch 14. By providing the granular vibration-damping fluid medium 12, the device can absorb vibrations while adjusting the overall mass of the base 1 by adding or discharging the mass of the vibration-damping fluid medium 12.

[0048] In this embodiment, the vibration-damping fluid medium 12 may be quartz sand.

[0049] See also Figure 6 and Figure 7 The blocking component 15 includes: a block 151 and a block bar 152. The block 151 is consistent with the current state of the notch 14 and is slidably assembled in the notch 14 along a direction perpendicular to the length of the base 1. L-shaped placement racks 153 are provided on both sides of the notch 14. The block bar 152 is arranged on the two L-shaped placement racks 153. By arranging the block 151 and the block bar 152 and disassembling the block 151, the vibration-damping fluid medium 12 can be quickly adjusted or discharged, and the operation is more convenient and quick.

By providing a plurality of exhaust holes 2332, the flow rate of the exhaust gas discharged to the outlet of the discharge pipe 233 can be reduced, thereby avoiding the surging phenomenon of the discharge pipe 233. At the same time, the discharge pipe 233 can be quickly disassembled and assembled by means of threaded connection.

[0051] In summary, when the device is working, the driving shaft of the diesel engine 2 rotates and drives the rotor of the generator 33 to rotate, and then the mechanical energy of the diesel engine 2 is converted into the electrical energy of the generator 33. At the same time, the generator 33 generates heat when generating electricity. After the heat is absorbed by the heat exchange fluid medium 4, it is transferred from the heat exchange tube assembly 31 to the preheating tube assembly 22, thereby realizing the preheating of the air in the intake pipe 21, so as to improve the combustion efficiency of the diesel engine 2; At the same time, the heat exchange fluid medium 4 can also absorb the vibration generated by the device during operation, thereby reducing the noise generated when the device is used; When the device is working, the natural frequency of the base 1 can be changed by increasing or decreasing the weight of the vibration-damping fluid medium 12, so that the base 1 can adjust its weight according to the operating frequency of the diesel engine 2 to avoid resonance. At the same time, the vibration-damping fluid medium 12 can further absorb vibration to reduce noise.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
