Description

Technical Field

[0001] This utility model relates to the field of generator sets, and in particular to a mobile low-noise generator set. Background Technology

[0002] A generator set is a device that converts other forms of energy (such as thermal energy, hydropower, wind power, solar energy, etc.) into electrical energy. Its core function is to provide power support in scenarios where grid power is unavailable or backup power is required.

[0003] However, existing generator sets have the problem of high noise in actual use. Traditional vibration reduction structures rely on only a single spring or damper and lack a multi-level buffering mechanism, which makes it impossible to effectively disperse the vibration energy during the operation of the unit. This not only generates high-decibel noise but also easily causes structural resonance, shortening the equipment life. Secondly, the equipment needs to be moved by external hoisting tools and is not equipped with a directional locking mechanism, resulting in low efficiency in relocation in complex terrain environments and failing to meet the needs of rapid deployment of emergency power supply. In order to solve the above problems, we propose a mobile low-noise generator set. Utility Model Content

[0004] The main objective of this invention is to provide a mobile, low-noise generator set that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mobile low-noise generator set includes a generator set body. Lifting rings are fixedly connected to the four corners of the upper end of the generator set body. Multiple buffer components are provided at the lower end of the generator set body. The lower ends of the multiple buffer components are fixedly connected to a base. Universal wheels are installed at the four corners of the lower end of the base. Limiting posts are fixedly connected to the front and rear ends of the base. Sliding columns are slidably connected to the inner sides of two of the limiting posts. The two sliding columns are respectively fixedly connected to the front and rear ends of the generator set body.

[0007] Preferably, the buffer assembly includes a mounting top plate, which is fixedly connected to the lower end of the generator set body. A connecting block is fixedly connected to the lower end of the mounting top plate, and multiple elastic pads are fixedly connected to the lower end of the connecting block. A buffer plate is fixedly connected to the lower end of the multiple elastic pads. A second damper is fixedly connected to the lower end of the buffer plate, and a support plate is fixedly connected to the lower end of the second damper. A mounting base plate is fixedly connected to each of the four corners of the lower end of the support plate, and the mounting base plate is fixedly installed on the lower end of the inner wall of the base.

[0008] Preferably, four buffer springs are provided on the outer side of the second damper, and the upper and lower ends of the four buffer springs are respectively fixedly connected to the buffer plate and the support plate.

[0009] Preferably, four rotating seats are fixedly connected to the outer side of the buffer plate, and corresponding rotating connectors are rotatably connected to the inner side of each of the four rotating seats. A first damping element is fixedly connected to the lower end of each rotating connector, and the lower end of the first damping element is rotatably connected to the support plate.

[0010] Preferably, a limiting groove is formed on the inner side of the limiting post, and the sliding post is slidably connected to the inner side of the limiting post through the limiting groove.

[0011] Preferably, a locking mechanism is provided on the outer side of the caster wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This mobile low-noise generator set, through a multi-stage synergistic buffer structure consisting of elastic pads, buffer springs, a first damping element, and a second damping element, effectively disperses and absorbs the vibration energy of the generator set. The elastic pads provide initial buffering, the buffer springs and the second damping element work together for secondary buffering, and the first damping element cooperates to form a tertiary buffer. The multi-stage vibration reduction mechanism significantly reduces the vibration amplitude during generator operation, effectively reduces the generation of high-decibel noise, avoids structural resonance, and extends the service life of the equipment.

[0014] 2. This mobile low-noise generator set, equipped with a locking mechanism on the universal wheels at the bottom of the base, can be moved flexibly and positioned quickly as needed, meeting the requirements for rapid deployment of emergency power supply. Combined with the lifting ring design at the top, it facilitates overall lifting and transportation, improving relocation efficiency. The sliding cooperation between the limit column and the sliding column ensures that the generator set does not shift laterally when damping vertically, enhancing the stability of the equipment during operation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a mobile low-noise generator set includes a generator set body 1. Lifting rings 2 are fixedly connected to the four corners of the upper end of the generator set body 1. Multiple buffer components 7 are provided at the lower end of the generator set body 1. The lower ends of the multiple buffer components 7 are fixedly connected to a base 3. Universal wheels 8 are installed at the four corners of the lower end of the base 3. Limiting posts 4 are fixedly connected to the front and rear ends of the base 3. Sliding columns 6 are slidably connected to the inner sides of the two limiting posts 4. The two sliding columns 6 are respectively fixedly connected to the front and rear ends of the generator set body 1.

[0023] In this embodiment, the buffer assembly 7 includes a mounting top plate 71, which is fixedly connected to the lower end of the generator set body 1. A connecting block 72 is fixedly connected to the lower end of the mounting top plate 71. A plurality of elastic pads 73 are fixedly connected to the lower end of the connecting block 72. A buffer plate 74 is fixedly connected to the lower end of the plurality of elastic pads 73. A second damper 710 is fixedly connected to the lower end of the buffer plate 74. A support plate 78 is fixedly connected to the lower end of the second damper 710. A mounting base plate 711 is fixedly connected to each of the four corners of the lower end of the support plate 78. The mounting base plate 711 is fixedly installed on the lower end of the inner wall of the base 3.

[0024] Specifically, when the generator set body 1 vibrates during operation, the vibration is transmitted to the elastic pad 73 through the mounting plate 71 for initial buffering. Its elastic deformation absorbs part of the vibration energy. Then the vibration is transmitted to the buffer plate 74, and the buffer plate 74 has a second damping 710. The two work together to perform secondary buffering, further consuming the vibration energy.

[0025] In this embodiment, four buffer springs 79 are provided on the outer side of the second damper 710. The upper and lower ends of the four buffer springs 79 are fixedly connected to the buffer plate 74 and the support plate 78, respectively. Four rotating seats 75 are fixedly connected to the outer side of the buffer plate 74. Corresponding rotating connectors 76 are rotatably connected to the inner side of the four rotating seats 75. The lower end of the rotating connector 76 is fixedly connected to the first damping element 77. The lower end of the first damping element 77 is rotatably connected to the support plate 78.

[0026] Specifically, while the buffer plate 74 is displaced, the first damping element 77 is rotated and compressed or stretched by the swivel 75 to form a three-stage buffer structure, achieving multi-stage vibration reduction and noise reduction. Furthermore, the four buffer springs 79 work together to further reduce the vibration of the generator set.

[0027] In this embodiment, a limiting groove 5 is provided on the inner side of the limiting post 4, and the sliding post 6 is slidably connected to the inner side of the limiting post 4 through the limiting groove 5.

[0028] Specifically, the sliding engagement between the limiting column 4 and the sliding column 6 ensures that the generator body 1 does not shift laterally during vertical vibration damping, thereby improving stability.

[0029] In this embodiment, a locking mechanism is provided on the outer side of the caster wheel 8.

[0030] Specifically, the locking mechanism on the caster wheel 8 enables flexible movement and positioning.

[0031] It should be noted that this utility model is a mobile low-noise generator set. When the generator set body 1 vibrates during operation, the vibration is transmitted to the elastic pad 73 through the mounting top plate 71 for initial buffering. Its elastic deformation absorbs part of the vibration energy. Then the vibration is transmitted to the buffer plate 74, which compresses the buffer spring 79 and the second damper 710. The two work together to perform secondary buffering, further consuming vibration energy. At the same time, the displacement of the buffer plate 74 drives the first damping element 77 to rotate, compress, or stretch through the swivel seat 75, forming a three-stage buffer structure to achieve multi-level vibration reduction and noise reduction. Through the sliding cooperation of the limiting column 4 and the sliding column 6, it can be ensured that the generator set body 1 does not shift laterally when damping vibration in the vertical direction, thereby improving stability. The locking mechanism on the universal wheel 8 can achieve flexible movement and positioning. The lifting ring 2 facilitates overall lifting and transportation, making it quite practical.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
