[0021] Please refer to the following: Figures 1 to 8 The following describes the diesel generator base structure with vibration damping and noise reduction functions provided in this embodiment of the utility model. Please refer to the following for further details. Figure 1 , Figure 2 and Figure 4The diesel generator base structure with vibration reduction and noise reduction function provided in this embodiment of the utility model includes a support structure 1 and a first vibration damping mechanism 2. The support structure 1 includes a first base 11, a second base 12, a mounting seat 13 for assembling and supporting the diesel engine and generator set, and a reinforcing beam 14 connecting the first base 11 and the second base 12. The first vibration damping mechanism 2 is disposed on the first base 11 and the second base 12, and the mounting seat 13 can be supported on the first base 11 and the second base 12 by the first vibration damping mechanism 2. The first damping mechanism 2 includes multiple hydraulic sleeves 21 storing hydraulic oil, multiple first pistons 22 corresponding to each hydraulic sleeve 21, multiple first sliding rods 23 corresponding to each first piston 22, and multiple first springs 24 corresponding to each first sliding rod 23. The first seat 11 and the second seat 12 are each provided with an equal number of hydraulic sleeves 21. Each first piston 22 is slidably disposed in its corresponding hydraulic sleeve 21. Each first sliding rod 23 is slidably inserted into its corresponding hydraulic sleeve 21 along the axial direction. The bottom end of each first sliding rod 23 is fixedly connected to its corresponding first piston 22, and the top end of each first sliding rod 23 is fixedly connected to its mounting base 13. Each first spring 24 is sleeved on its corresponding first sliding rod 23, and the bottom end of each first spring 24 is fixedly connected to the top end of its corresponding hydraulic sleeve 21. The top end of each first spring 24 is fixedly connected to the top end of its corresponding first sliding rod 23. The diesel generator base structure with shock absorption and noise reduction function provided in this embodiment of the utility model uses the first base body 11 and the second base body 12 as the foundation that can bear the weight of the unit and dynamic impact load, providing a stable support platform for the entire diesel generator. Multiple hydraulic sleeves 21 are respectively provided on the first base body 11 and the second base body 12. A first piston 22 that can compress the hydraulic oil in the hydraulic sleeve 21 is slidably arranged in each hydraulic sleeve 21, and a first sliding rod 23 is slidably connected in each hydraulic sleeve 21. As long as the bottom end of each first sliding rod 23 is fixedly connected to the corresponding first piston 22 and the top end of each first sliding rod 23 is fixedly connected to the mounting base 13, the mounting base 13 can be supported on the first base body 11 and the second base body 12 by the first shock absorption mechanism 2.Furthermore, a first spring 24 is sleeved on each of the first sliding rods 23. The bottom end of each first spring 24 is fixedly connected to the top end of the corresponding hydraulic sleeve 21, and the top end of each first spring 24 is fixedly connected to the top end of the corresponding first sliding rod 23. The vibration generated by the operation of the diesel generator on the mounting base 13 is first absorbed by the elastic deformation of the multiple first springs 24 to absorb the primary vibration energy. While the multiple first springs 24 are compressed, each first sliding rod 23 slides downward along the axial direction to push the corresponding first piston 22 to compress the hydraulic oil in the corresponding hydraulic sleeve 21. This allows the hydraulic oil compressed in each hydraulic sleeve 21 to jointly dampen the mounting base 13, effectively absorbing the remaining vibration energy and achieving a deeper level of vibration control. Thus, the diesel generator base structure with vibration reduction and noise reduction function provided by this utility model embodiment can play a good buffering and vibration reduction effect on the vibration generated during the operation of the diesel generator, reduce the vibration and noise during the operation of the diesel generator, improve the vibration reduction and noise reduction performance of the diesel generator base, thereby improving the user experience and ensuring the long-term efficient and stable operation of the diesel generator.

[0022] The diesel generator base structure with shock absorption and noise reduction function provided in this embodiment of the utility model, compared with the prior art, is achieved by setting multiple hydraulic sleeves 21 on the first base body 11 and the second base body 12 respectively, sliding a first piston 22 in each hydraulic sleeve 21, and sliding a first sliding rod 23 in each hydraulic sleeve 21. By simply fixing the bottom end of each first sliding rod 23 to the corresponding first piston 22 and fixing the top end of each first sliding rod 23 to the mounting base 13, the mounting base 13 can be supported on the first base body 11 and the second base body 12 by the first shock absorption mechanism 2. Since each first sliding rod 23 is fitted with a first spring 24, the vibration generated by the operation of the diesel generator on the mounting base 13 is first absorbed by the elastic deformation of the multiple compressed first springs 24. Then, each first sliding rod 23 slides downward along the axial direction to push the corresponding first piston 22 to compress the hydraulic oil in the corresponding hydraulic sleeve 21. The hydraulic oil compressed in each hydraulic sleeve 21 works together to dampen the mounting base 13, effectively absorbing the remaining vibration energy. Therefore, it can play a good buffering and shock absorption role for the vibration generated during the operation of the diesel generator. At the same time, it can reduce the vibration and noise during the operation of the diesel generator, improve the vibration and noise reduction performance of the diesel generator base, thereby improving the user experience and ensuring the long-term efficient and stable operation of the diesel generator.

[0023] Please refer to the following: Figure 5 and Figure 6In some embodiments, each hydraulic sleeve 21 includes a sleeve body 211 fixedly mounted on a first base 11 or a second base 12, a first flange 212 disposed at the top opening of the sleeve body 211, a second flange 213 capable of sealingly connecting with the first flange 212, and a plurality of first bolts fastening the second flange 213 to the first flange 212. The diameter of the central hole of the second flange 213 is smaller than the inner diameter of the sleeve body 211, and each first sliding rod 23 is slidably inserted into the central hole of the corresponding second flange 213. In this embodiment, by providing a sleeve body 211 on the first base 11 or the second base 12 and providing a first flange 212 at the top opening of the sleeve body 211, with the central hole diameter of the first flange 212 equal to the inner diameter of the sleeve body 211, it is convenient to install the first piston 22 into the sleeve body 211. Meanwhile, the second flange 213 is fastened to the first flange 212 by the first bolt. The first sliding rod 23 can be slidably inserted into the sleeve body 211 simply by sliding it into the center hole of the second flange 213. It should be noted that the first sliding rod 23 is made of stainless steel.

[0024] Please refer to the following: Figure 4 , Figure 5 and Figure 6 In some embodiments, each first sliding rod 23 has a support tray 25 at its top for supporting the mounting base 13. The first damping mechanism 2 also includes a plurality of second bolts for fastening each support tray 25 to the mounting base 13. Each support tray 25 has a plurality of first through holes spaced apart along its circumference for the second bolts to pass through. The mounting base 13 has first threaded holes that thread into the second bolts. The top of each first spring 24 is fixedly connected to the corresponding support tray 25. In this embodiment, the fixed connection between each first sliding rod 23 and the mounting base 13 can be achieved simply by fixing each support tray 25 to the mounting base 13 with the second bolts. By providing a support tray 25 at the top of the first sliding rod 23, the contact area with the mounting base 13 can be increased, improving the stability and reliability of the mounting base 13 supported on the first damping mechanism 2.

The two second vibration damping mechanisms 3 are symmetrically arranged on both sides of the reinforcing beam 14. In this embodiment, the second vibration damping mechanism 3 assists the first vibration damping mechanism 2 in vibration damping. The multi-stage vibration damping setting can effectively buffer and dampen the vibration generated during the operation of the diesel generator, while reducing the vibration and noise during the operation of the diesel generator.

[0026] Please refer to the following: Figure 4 , Figure 7 and Figure 8In some embodiments, each second shock-absorbing mechanism 3 includes an explosion-proof steel pipe 31 disposed between the first seat 11 and the second seat 12, a second piston 32 slidably disposed in the explosion-proof steel pipe 31, a third piston 33 slidably disposed in the explosion-proof steel pipe 31, a first support disc 34 fixedly connected to the second piston 32, a sliding sleeve 35 fixedly connected to the first support disc 34, a second support disc 36 fixedly connected to the third piston 33, a second sliding rod 37 fixedly connected to the second support disc 36, and a second spring 38 sleeved on the sliding sleeve 35.

The second seat 12 is provided with a second liquid storage chamber 121 that is connected to the corresponding hydraulic sleeve 21. The second end of the explosion-proof steel pipe 31 is connected to the second liquid storage chamber 121. The part of the explosion-proof steel pipe 31 located between the first piston 22 and the second piston 32 forms an air compression chamber 4, and the rest of the explosion-proof steel pipe 31 is filled with hydraulic oil. In this embodiment, when the first piston 22 compresses the hydraulic oil in the corresponding hydraulic sleeve 21, the compressed hydraulic oil can squeeze the second piston 32 and the third piston 33 in the explosion-proof steel pipe 31 to move towards each other. On the one hand, it can compress the air in the air compression chamber 4 of the explosion-proof steel pipe 31, so that the compressed air can dampen the vibration of the mounting base 13. On the other hand, since the air compression chamber 4 is provided with a sliding connection between the second sliding rod 37 and the sliding sleeve 35, during the process of the second piston 32 and the third piston 33 approaching each other, the first support disc 34 and the second support disc 36 respectively squeeze the sliding sleeve 35 and the second sliding rod 37, so that the second sliding rod 37 retracts into the sliding sleeve 35. At this time, the second spring 38 between the first support disc 34 and the second support disc 36 can further play a damping and shock absorption role, thereby improving the vibration reduction and noise reduction effect.

The support structure 1 also includes a sealing member 15 for closing the receiving port 112, a sealing member 16 disposed between the sealing member 15 and the first seat 11, and a plurality of third bolts for fastening the sealing member 15 to the first seat 11.

One end of the third spring 39 abuts against the inner bottom surface of the sliding sleeve 35, and the other end of the third spring 39 abuts against the end of the second sliding rod 37 inserted into the sliding sleeve 35. In this embodiment, as the second sliding rod 37 gradually retracts into the sliding sleeve 35, the third spring 39 can further play a damping and shock-absorbing role, thereby improving the shock absorption and noise reduction effect.
