[0001] This invention relates to the field of diesel generator technology, specifically to a vibration-damping and noise-reducing diesel generator. Background Art
[0002] A diesel generator is a small power generation device that uses diesel fuel and a diesel engine as the prime mover to drive a generator to generate electricity. As shown in the patent application "A Low-Noise Diesel Generator Set" (CN117988973A), it includes a chassis with a partition fixedly installed inside. A diesel engine and a generator are fixedly mounted on the partition, which also has a cleaning mechanism. A collection box is fixedly installed at the bottom of the partition, and an inner box is fixedly installed inside the collection box. A support plate is fixedly installed inside the inner box, and a first motor is fixedly mounted on the support plate. A collection mechanism is provided inside the collection box.

A vertical rotating rod is fixedly connected to the output shaft of the second motor, and an exhaust fan blade is fixedly connected to the bottom end of the vertical rotating rod. A protective box is fixedly installed inside the heat dissipation box. Two heat dissipation cylinders are located on the top of the housing, each containing a mesh screen.

A base is fixedly installed at the bottom of the housing, and a third motor is fixedly installed on one side of the base. Two support seats are fixedly installed at the bottom of the base. However, the above structure still has the following problems in actual use:
[0003] Because diesel generators themselves generate significant vibrations, and the aforementioned structure has a fixed connection between the diesel generator and the partition, the connection can easily be damaged when the diesel generator vibrates, leading to loosening of the connection and failure to provide cushioning and shock absorption. Furthermore, the rigid connection method results in significant noise, which can easily cause noise pollution.
[0004] Therefore, we proposed that vibration-damping and noise-reducing diesel generators can effectively solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a vibration-damping and noise-reducing diesel generator to solve the problems mentioned in the background art, such as the fact that the connection structure of diesel generators on the market is easily damaged when the whole structure vibrates, which leads to the loosening of the connection structure and the inability to achieve the effect of buffering and vibration reduction. Moreover, the rigid connection method leads to greater noise and thus easily causes noise pollution.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a vibration-damping and noise-reducing diesel generator, comprising a base and a soundproof shell installed on the upper surface of the base for sound insulation and noise reduction;
[0007] It also includes: a diesel generator body is provided above the base, and the soundproof shell completely covers the diesel generator body. At the same time, a connecting seat is fixed on the lower end face of the diesel generator body, and the lower end of the connecting seat is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the sliding column.
[0008] A shock absorption mechanism is provided below the main body of the diesel generator, and the shock absorption effect is achieved through the cooperation between the first shock absorber and the second shock absorber.
[0009] The diesel generator body is equipped with heat dissipation mechanisms on both the front and rear sides, which achieve heat dissipation by air flowing in the heat dissipation pipes.
[0010] Preferably, the shock absorption mechanism includes a sliding column and a first shock absorber, wherein the sliding column is slidably disposed on the inner side of the base, and two sets of sliding columns are provided, and the outer side of the sliding column is fixed to one end of the first shock absorber, while the other end of the first shock absorber is fixed to the base.
[0011] Preferably, the lower end face of the diesel generator body is fixed to the upper end of the second shock absorber, and the lower end of the second shock absorber is fixed to the fixing column, and both the front and rear ends of the fixing column are fixedly connected to the base.
[0012] Preferably, the heat dissipation mechanism includes a sleeve rod and an extrusion plate, wherein one end of the sleeve rod is fixed to the inner side of the sliding column, and the other end of the sleeve rod extends into the sleeve and is fixed to the extrusion plate, and the sleeve and the sleeve rod are in a sliding connection structure, and the inner end of the sleeve is fixed to the outer side of the fixed column.
[0013] Preferably, the upper end face of the sleeve is connected to and fixed with an air inlet, and the outer side of the sleeve is connected to one end of the air intake pipe. At the same time, the other end of the air intake pipe is connected to the split pipe. The split pipe is arranged on the front and rear sides of the diesel generator body. The upper end face of the split pipe is connected to and fixed with heat dissipation pipes at equal intervals. The upper end of the heat dissipation pipe extends out of the upper end face of the sound insulation shell.
[0014] Preferably, a sliding rod is fixed to the inner side of the sliding column, and toothed blocks are evenly distributed on the inner side of the right end of the sliding rod. At the same time, the sliding rod and the base form a sliding connection, and the toothed blocks form a meshing connection with the gear.
[0015] Preferably, the full gear is provided in two sets, and a rotating rod is fixed in the middle of each set of full gears. The lower end of the rotating rod is rotatably connected to the base, while the upper end of the rotating rod is fixed to the bevel gear set.
[0016] Preferably, the outer side of the bevel gear set is fixed to one end of the rotating shaft, and the other end of the rotating shaft passes through the heat dissipation port and forms a bearing connection structure with the heat dissipation port. At the same time, the outer side of the outer end of the rotating shaft is fixed to the cleaning rod.
[0017] Preferably, the cleaning rod has brushes evenly distributed on its inner side, and the brushes are in close contact with the surface of the heat dissipation vent, and the heat dissipation vent is installed on the front and rear sides of the soundproof housing.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This vibration-damping and noise-reducing diesel generator not only achieves the effect of vibration reduction, but also further enhances the vibration reduction effect. Furthermore, the addition of a second vibration damper further improves the vibration reduction effect and reduces noise generation through vibration reduction, making it highly practical. Moreover, when air flows through the cooling pipe, it carries away the heat generated by the diesel generator body during operation, thereby achieving a heat dissipation effect. It can also clean the dust adhering to the surface of the cooling vents, preventing dust accumulation from hindering heat dissipation. The specific details are as follows:
[0019] (1) The first shock absorber not only achieves the effect of shock absorption, but also effectively counteracts the vibration generated by the main body of the diesel generator, thereby achieving the effect of shock absorption. The second shock absorber further enhances the shock absorption effect and also reduces the noise generated through shock absorption, making it highly practical.
[0020] When the main body of the diesel generator vibrates and descends, it will drive one end of the rotating connecting rod to descend together through the fixed connecting seat. Through the rotating connection between the other end of the connecting rod and the sliding column, it will squeeze the sliding column outward in the base, and thus squeeze the first shock absorber while the sliding column slides outward.
[0021] (2) The air inside the sleeve enters the split pipe through the air inlet pipe and then is split into the heat dissipation pipe. When the air flows in the heat dissipation pipe, it will carry away the heat generated by the main body of the diesel generator during operation, thereby achieving the heat dissipation effect.
[0022] By setting up the air inlet, external air can be drawn into the sleeve, thus filling the sleeve with air. At the same time, a one-way valve is set on the outside of the air inlet, which ensures that air can only enter the sleeve through the air inlet, while the air in the sleeve cannot leave through the air inlet.
[0023] (3) The brush is rotated by the cleaning rod to clean the dust attached to the surface of the heat dissipation port. This can avoid the problem of dust accumulation causing the heat dissipation port to be unable to dissipate heat. Moreover, no separate drive source is required to drive it, which saves the manufacturing cost of the device. It also avoids the problem of using a separate drive source to further increase the internal temperature of the soundproof shell, which would affect the heat dissipation effect of the diesel generator body.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] See also Figures 1-8 The present invention provides the following technical solution:
[0035] Example 1: To address the problems in the prior art where the overall vibration of a diesel generator easily damages the connection structure, leading to loosening and failure to provide cushioning and vibration reduction, and where rigid connections result in significant noise pollution, the following solution is disclosed: a base 1 and a soundproof outer shell 2 mounted on the upper surface of the base 1 for sound insulation and noise reduction; a diesel generator body 3 is positioned above the base 1, and the soundproof outer shell 2 completely encloses the diesel generator body 3. A connecting seat 4 is fixed to the lower surface of the diesel generator body 3, with the lower end of the connecting seat 4 rotatably connected to one end of a connecting rod 5, and the other end of the connecting rod 5 rotatably connected to a sliding column 6; A shock-absorbing mechanism is provided below the main body 3 of the diesel generator. The shock absorption effect is achieved through the cooperation between the first shock absorber 7 and the second shock absorber 9. A heat dissipation mechanism is provided on the front and rear sides of the main body 3 of the diesel generator. The purpose of heat dissipation is achieved by the flow of air in the heat dissipation pipe 16. The shock-absorbing mechanism includes a sliding column 6 and a first shock absorber 7. The sliding column 6 is slidably disposed on the inner side of the base 1. There are two sets of sliding columns 6. The outer side of the sliding column 6 is fixed to one end of the first shock absorber 7. At the same time, the other end of the first shock absorber 7 is fixed to the base 1. The lower end of the main body 3 of the diesel generator is fixed to the upper end of the second shock absorber 9. The lower end of the second shock absorber 9 is fixed to the fixed column 8. The front and rear ends of the fixed column 8 are fixedly connected to the base 1.
[0036] Firstly, a soundproof outer shell 2 is provided on the outside of the diesel generator body 3. The soundproof outer shell 2 covers the diesel generator body 3, thereby achieving a sound insulation effect and effectively reducing noise. Simultaneously, when the diesel generator body 3 vibrates and descends, it will drive one end of the rotatably connected connecting rod 5 to descend along with it via the fixed connecting seat 4. Through the rotatable connection between the other end of the connecting rod 5 and the sliding column 6, it will compress the sliding column 6 and make it slide outward within the base 1. This outward sliding of the sliding column 6 compresses the first shock absorber 7, thereby effectively reducing noise. The force generated by the sliding column 6 is used for buffering and shock absorption, thereby achieving the effect of shock absorption. It can effectively counteract the vibration generated by the diesel generator body 3, thus achieving the effect of shock absorption. At the same time, it can also provide a certain degree of protection for the diesel generator body 3. Meanwhile, the lower end of the diesel generator body 3 is also fixed to the upper end of the second shock absorber 9, and the lower end of the second shock absorber 9 is fixed to the fixed column 8. When the diesel generator body 3 descends and squeezes the second shock absorber 9, the setting of three sets of second shock absorbers 9 further achieves the effect of shock absorption. It not only achieves the function of shock absorption, but also reduces the generation of noise through shock absorption, which has good practicality.
[0037] Example 2: Based on Example 1, a new technical solution is added so that when air flows through the cooling pipe 16, it carries away the heat generated by the diesel generator body 3 during operation, thereby achieving a heat dissipation effect. See details for further information. Figure 2 and Figure 5-Figure 6 The heat dissipation mechanism includes a sleeve rod 10 and an extrusion plate 11. One end of the sleeve rod 10 is fixed to the inner side of the sliding column 6, and the other end of the sleeve rod 10 extends into the sleeve 12 and is fixed to the extrusion plate 11. The sleeve 12 and the sleeve rod 10 are in a sliding connection structure. The inner end of the sleeve 12 is fixed to the outer side of the fixed column 8. The upper end face of the sleeve 12 is connected to and fixed with an air inlet 13. The outer side of the sleeve 12 is connected to one end of the air intake pipe 14. At the same time, the other end of the air intake pipe 14 is connected to the split pipe 15. The split pipe 15 is arranged on the front and rear sides of the diesel generator body 3. The upper end face of the split pipe 15 is connected to and fixed with heat dissipation pipes 16 at equal intervals. The upper end of the heat dissipation pipes 16 extends out of the upper end face of the sound insulation shell 2.
[0038] As the sliding column 6 moves outward, it also drives the sleeve rod 10 to move outward together. This causes the sleeve rod 10 to drive the extrusion disc 11 to slide outward within the sleeve 12, generating suction. Through the air inlet 13, external air can be drawn into the sleeve 12, filling it with air. A one-way valve is installed on the outside of the air inlet 13, ensuring that air can only enter the sleeve 12 through the air inlet 13, while air in the sleeve 12 cannot escape through it. When the first shock absorber 7 drives the sliding column 6 to slide inward... When the motor resets, it also moves the sleeve rod 10 inward, which in turn moves the extrusion plate 11. This causes the extrusion plate 11 to extrude air from the sleeve 12, which is then forced into the air intake pipe 14. The air then enters the splitter pipe 15 through the air intake pipe 14 and is then split into the cooling pipe 16. As the air flows through the cooling pipe 16, it carries away the heat generated by the diesel generator body 3 during operation, thus achieving a heat dissipation effect and improving the practicality of the structure.
[0039] Example 3: Based on Example 1, a new technical solution is added to clean the dust adhering to the surface of the heat dissipation vent 25, thus avoiding the problem of dust accumulation causing the heat dissipation vent 25 to fail to dissipate heat. See details for further information. Figure 1 and Figures 6-8A sliding rod 17 is fixed to the inner side of the sliding column 6, and toothed blocks 18 are evenly distributed on the inner side of the right end of the sliding rod 17. The sliding rod 17 and the base 1 form a sliding connection, and the toothed blocks 18 form a meshing connection with the full gear 19. There are two sets of full gears 19, and a rotating rod 20 is fixed in the middle of each set of full gears 19. The lower end of the rotating rod 20 is rotatably connected to the base 1, and the upper end of the rotating rod 20 is fixed to the bevel gear set 21. The outer side of the bevel gear set 21 is fixed to one end of the rotating shaft 22, and the other end of the rotating shaft 22 passes through the heat dissipation port 25 and forms a bearing connection structure with the heat dissipation port 25. The outer side of the outer end of the rotating shaft 22 is fixed to the cleaning rod 23. Brushes 24 are evenly distributed on the inner side of the cleaning rod 23, and the brushes 24 are tightly attached to the surface of the heat dissipation port 25. The heat dissipation port 25 is installed on the front and rear sides of the soundproof shell 2.
[0040] Furthermore, as the sliding column 6 resets inward, it also drives the sliding rod 17 to reset. Simultaneously, the sliding rod 17, through the meshing of the toothed block 18 and the full gear 19, causes the full gear 19 to rotate. This rotation of the full gear 19, in turn, causes the rotating rod 20, which is fixed in the middle, to rotate. This rotation of the rotating rod 20, in turn, causes the bevel gear set 21, fixed at its upper end, to rotate. The rotation of the bevel gear set 21, in turn, causes the rotating shaft 22 to rotate. The outer end of the rotating shaft 22 extends out to form the soundproof outer shell 2, which is fixed to the cleaning rod 23. Therefore, when the shaft 22 rotates, it also drives the cleaning rod 23 to rotate together. This causes the cleaning rod 23 to rotate while the brushes 24, which are evenly distributed on its inner side, move together. Through the contact between the brushes 24 and the heat dissipation vent 25, the dust attached to the surface of the heat dissipation vent 25 is cleaned. This can prevent the problem of dust accumulation causing the heat dissipation vent 25 to be unable to dissipate heat. Moreover, no separate drive source is required to drive it, which saves the manufacturing cost of the device. At the same time, it also avoids the problem of using a separate drive source causing the internal temperature of the soundproof shell 2 to increase further, thereby affecting the heat dissipation effect of the diesel generator body 3.
