Description

Technical Field

[0001] The present invention relates to the technical field of diesel generators, and in particular to a diesel generator set with a noise reduction function. Background Art

[0002] Diesel generator sets are commonly used as backup or mobile power sources. When running, they are accompanied by significant mechanical noise and exhaust noise, which interferes with the surrounding sound environment. Existing technology often uses soundproof shells to wrap the units to reduce noise, but this often limits the internal heat dissipation airflow channel, causing heat accumulation that affects equipment performance and life. At the same time, if the strong vibration during operation of the unit is transmitted to the shell, it is easy to cause secondary impact noise.

[0003] Existing noise reduction solutions are in conflict with ensuring good heat dissipation and completely isolating noise. Fixed heat dissipation holes become the main channel for noise leakage, while internal heat is difficult to discharge evenly. In addition, relying solely on elastic supports is difficult to completely and effectively isolate the vibration of the unit, especially to prevent it from being transmitted to the outer casing to generate additional noise. How to achieve efficient heat dissipation, completely block noise transmission and effectively absorb unit vibration has become a problem that needs to be solved urgently.

[0019] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example 1

[0020] like Figure 1-Figure 4 As shown, an embodiment of the present invention proposes a diesel generator set with a noise reduction function, including a generator set body 1 and a soundproof shell 2. The generator set body 1 serves as a core power generation unit, and a base 3 is fixedly connected to the bottom of the generator set. The base 3 provides a stable installation foundation for the set. The inner bottom of the soundproof shell 2 is fixedly connected to a telescopic rod 4. The telescopic rod 4 is used to absorb and buffer the vertical vibration during the operation of the set, and the base 3 is fixedly connected to the upper side of the telescopic rod 4. The number of telescopic rods 4 is several groups and arranged in an array. This arrangement ensures the uniformity and stability of vibration absorption.

[0021] like Figure 2 as well as Figure 4 As shown, one side of the telescopic rod 4 is fixedly connected to a fixed plate 5, which serves as the installation base of the connecting structure. The upper side thereof is slidingly connected to a connecting seat 6, which is used to convert and transmit vibration energy. A slide groove 7 is provided on the outside of the fixed plate 5, and a slider 8 is fixedly connected to the lower side of the connecting seat 6. The cooperation between the slider 8 and the slide groove 7 realizes the precise guiding movement of the connecting seat 6, and the slider 8 is slidingly connected to the inner side of the slide groove 7.

[0022] like Figure 2 as well as Figure 4 As shown, a diagonal support mechanism is installed between one side of the connecting seat 6 and the base 3. The diagonal support mechanism includes a first rotating member 9, a second rotating member 10 and a diagonal support rod 11. The first rotating member 9 is fixedly connected to the outside of the connecting seat 6, and the second rotating member 10 is fixedly connected to the bottom of the base 3. The diagonal support rod 11 converts vertical vibration into lateral displacement through a rotational connection. The diagonal support rod 11 is rotationally connected between the first rotating member 9 and the second rotating member 10.

[0023] like Figure 2 as well as Figure 4 As shown, a buffer mechanism is installed between the other side of the connecting seat 6 and the telescopic rod 4. The buffer mechanism includes a damper 12 and a compression spring 13. The damper 12 is used to quickly consume vibration energy, and the compression spring 13 provides elastic restoring force. The damper 12 and the compression spring 13 are both fixedly connected between the telescopic rod 4 and the connecting seat 6, and the compression spring 13 is sleeved on the outside of the damper 12. This combined design achieves an efficient shock absorption effect.

[0024] like Figure 6 As shown, the bottom of the sound insulation shell 2 is fixedly connected with four groups of bottom rods 30 arranged in an array. The bottom rods 30 serve as the installation base of the support structure. The outside of the bottom rods is slidably connected with support feet 31. The support feet 31 are used to isolate the transmission of ground vibrations. The inner side of the support feet 31 is fixedly connected with elastic pads 32. The elastic pads 32 further absorb and cushion vibrations, and the bottom rods 30 abut against the upper side of the elastic pads 32.

[0025] In this embodiment, when the generator set body 1 is generating electricity, it will generate strong noise and vibration. This noise can be absorbed and blocked by the soundproof shell 2 and the lower soundproof board 17, upper soundproof board 18 and slide plate 19 made of soundproof material, effectively reducing the outward transmission of noise. At the same time, when the generator set body 1 vibrates, the telescopic rod 4 connected to its base 3 limits the vibration mainly in the vertical direction. This vertical vibration is converted into a lateral thrust on the connecting seat 6 by the diagonal support rod 11 of the diagonal support mechanism, which in turn pushes the connecting seat 6 to move laterally and compresses the buffer mechanism. The buffer mechanism provides elastic restoring force for buffering through the compression spring 13, while the damper 12 suppresses rebound and continuous shaking. Together, they absorb vibration energy, thereby effectively preventing the generator set body 1 from vibrating and hitting the soundproof shell 2 and causing secondary noise. In addition, the bottom of the soundproof shell 2 absorbs and isolates vibration transmitted from the ground through the support feet 31 and the elastic pads 32 inside. The soundproof cotton 34 wrapped around the exhaust pipe 33 further blocks the exhaust noise. These measures together constitute a comprehensive noise reduction system, which significantly improves the acoustic quality of the working environment. Example 2

[0026] like Figures 1-8 As shown, on the basis of embodiment 1, a heat dissipation hole 14 is provided on one side of the soundproof shell 2. The heat dissipation hole 14 is used for heat dissipation of the unit. The number of the heat dissipation holes 14 is several groups and they are arranged vertically. A dust cover 15 is fixedly connected to the outside of the soundproof shell 2. The dust cover 15 prevents external dust from entering the interior of the unit, and the dust cover 15 covers the heat dissipation hole 14. A dust net 16 is provided on the lower side of the dust cover 15. The dust net 16 filters particulate matter in the air while ensuring ventilation.

[0027] like Figure 6 as well as Figure 7 As shown, a lower sound insulation board 17 and an upper sound insulation board 18 are symmetrically fixedly connected to one side of the interior of the sound insulation shell 2 near the heat dissipation hole 14. The lower sound insulation board 17 and the upper sound insulation board 18 together constitute a sound insulation barrier. A slide plate 19 is slidably connected between the lower sound insulation board 17 and the upper sound insulation board 18. The slide plate 19 is used to dynamically control the opening and closing of the heat dissipation channel. Both ends of the slide plate 19 are fixedly connected to a limit plate 20. The limit plate 20 limits the movement range of the slide plate 19. A tension spring 21 is fixedly connected to the inner side of the lower sound insulation board 17. The tension spring 21 provides a reset tension, and the other end of the tension spring 21 is fixedly connected to the lower side of the limit plate 20.

[0028] like Figure 7 as well as Figure 8 As shown, a lifting mechanism is installed on the inner side of the generator set body 1, and the lifting mechanism includes a drive motor 22, a rotating shaft 23 and a connecting rope 24. The drive motor 22 provides power output, and the rotating shaft 23 converts rotational motion. The drive motor 22 is fixedly connected to the outside of the soundproof shell 2, and the rotating shaft 23 is rotatably connected to the inside of the soundproof shell 2, and the rotating shaft 23 and the drive motor 22 are fixedly connected. The connecting rope 24 transmits traction, and the connecting rope 24 is fixedly connected to the outside of the rotating shaft 23. The end of the connecting rope 24 passes through the outside of the upper sound insulation board 18 and is fixedly connected to the upper side of the limit plate 20.

[0029] like Figure 3 as well as Figure 5 As shown, a heat dissipation mechanism is installed on the outside of the skateboard 19, and the heat dissipation mechanism includes a mounting base 25, a mounting rod 28 and a fan 29. The mounting base 25 serves as a mounting platform for the heat dissipation component. The mounting base 25 is fixedly connected to the outside of the skateboard 19, and the mounting base 25 is a hollow structure. An air inlet 26 is provided on one side of the mounting base 25, and the air inlet 26 introduces hot air. A ventilation net 27 is provided on the other side of the mounting base 25, and the ventilation net 27 discharges hot air. The mounting rod 28 is fixedly connected to the inside of the mounting base 25, and the fan 29 accelerates the air flow. The fan 29 is fixedly connected to the outside of the mounting rod 28. The upper and lower sides of the mounting base 25 are fixedly connected with pressure sensors 37. The pressure sensor 37 detects a position signal, and the pressure sensor 37 is communicated with the drive motor 22.

[0030] like Figure 3 As shown, the outside of the generator set body 1 is fixedly connected to an exhaust pipe 33, which discharges exhaust gas, and the exhaust pipe 33 protrudes from the upper surface of the sound insulation shell 2. The upper end of the sound insulation shell 2 is fixedly connected to sound insulation cotton 34, which reduces exhaust noise, and the exhaust pipe 33 passes through the sound insulation cotton 34. The outside of the sound insulation shell 2 is detachably connected to multiple groups of inspection panels 35, which facilitate equipment maintenance. The outside of the sound insulation shell 2 is provided with a wiring port 36, which is used for connecting power lines.

[0031] In this embodiment, when the generator set needs to dissipate heat, the fan 29 is started to suck the hot air generated by the generator set body 1 into its internal cavity through the air inlet 26 on one side of the mounting seat 25. The hot air is driven by the fan 29 to pass through the ventilation net 27 on the other side of the mounting seat 25, and then through the heat dissipation holes 14 on the sound insulation shell 2, and finally discharged to the external environment through the dustproof net 16 at the bottom of the dust cover 15 covering the heat dissipation holes 14. In order to achieve all-round and uniform heat dissipation inside the sound insulation shell 2, the drive motor 22 can be started at the same time to drive the rotating shaft 23 to rotate and wind the connecting rope 24. The connecting rope 24 pulls the slide plate 19 upward, so that the slide plate 19 slides upward along the track between the lower sound insulation board 17 and the upper sound insulation board 18. This process simultaneously stretches the tension spring 21 on the inner side of the lower sound insulation board 17, thereby dissipating heat to the area above the generator set body 1. When the slide plate 19 moves up to the pressure sensor 37 on the upper side of the mounting seat 25 and abuts against the upper sound insulation board 18, the pressure sensor 37 sends a signal to the drive motor 22 to reverse it, and the drive motor 22 reverses to release the connecting rope 24. The slide plate 19 slides downward under the combined action of its own gravity and the restoring force of the tension spring 21, and turns to dissipate heat to the area below it. When the slide plate 19 slides down to the pressure sensor 37 on the lower side of the mounting seat 25 and abuts the lower sound insulation board 17, the pressure sensor 37 triggers a signal again to make the drive motor 22 reverse and start to lift the slide plate 19 upward again. This cycle repeats, and the slide plate 19 moves up and down inside the sound insulation shell 2, driving the heat dissipation mechanism thereon to circulate and dissipate heat to the generator set body 1 in an all-round manner. The key is that the slide plate 19 always blocks the heat dissipation hole 14 channel in the area where the mounting seat 25 slides during the movement, effectively preventing the internal noise from escaping in large quantities through the open heat dissipation hole 14. This design not only achieves the requirements of efficient and dynamic heat dissipation, but also maintains the overall sound insulation effect of the sound insulation shell 2 to the greatest extent, ensuring low-noise operation.
