Description

Technical Field

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

[0002] Generator sets with soundproof enclosures, as opposed to open-type generator sets, have an added feature that provides sound insulation and rain protection. The enclosure encloses the open-type generator set, with sound-absorbing material adhered to the inner wall. It also includes air intake and exhaust vents for air intake and cooling. With my country facing increasingly severe power shortages and rising environmental protection standards, diesel generator sets with soundproof enclosures are widely used as backup power sources for the power grid due to their low noise levels. They are indispensable emergency equipment, especially in hospitals, hotels, upscale residential areas, and large shopping malls where environmental noise control is stringent.

[0003] For high-power generator sets, which are inherently noisy, only by achieving significant noise reduction can the noise level of the generator set meet current environmental protection requirements. Traditional enclosures have fixed outer shells during installation, and the noise reduction and insulation materials inside the enclosures are also fixed, making it impossible to replace the internal structure. Furthermore, when it is necessary to maintain the generator inside, the internal working space is small, which affects the efficiency of subsequent maintenance.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a soundproof enclosure for low-noise generator sets. This enclosure features an assembled structure, which increases the operating space when maintenance of the generator is required. It also includes an internal filling area to facilitate the installation and replacement of internal noise-reducing materials.

[0006] To achieve the above objectives, this utility model provides a silent enclosure for a low-noise generator set, comprising: An intermediate shell has openings at both ends, and the interior of the outer wall of the intermediate shell has a first filling space. Side sealing members are slidably installed at both ends of the intermediate housing to seal the openings. The side walls of the side sealing members have a second filling space that corresponds to the first filling space. During installation, the first and second filling spaces are filled with noise reduction material.

[0007] In one embodiment, the intermediate housing is provided with positioning plates at both ends, and the side sealing member is provided with positioning grooves corresponding to the positioning plates. The positioning plates and positioning grooves cooperate to restrict the position of the side sealing member and the intermediate housing.

[0013] In one embodiment, a double door is provided on one side of the intermediate housing, and the generator set is installed inside the intermediate housing.

[0014] This utility model provides a silent enclosure for low-noise generator sets, comprising: The intermediate shell has openings at both ends. The inner wall of the intermediate shell has a first filling space. The generator set is installed inside the intermediate shell to ensure normal installation of the generator set. At the same time, when the wind turbine needs to be maintained, the openings increase the operating space and facilitate the maintenance of the internal generator components. Side sealing components are slidably installed at both ends of the intermediate housing to seal the openings. During normal operation of the generator set, these side sealing components seal the openings in the intermediate housing, ensuring the generator set's noise reduction effect. The side walls of the side sealing components have a second filling space corresponding to the first filling space. During installation, both the first and second filling spaces are filled with noise-reducing material. This filling material ensures the noise reduction effect of the internal generator.

[0020] In one embodiment, see Figure 3 , Figure 4 and Figure 5To ensure that the position of the side sealing component 2 corresponds to the position of the intermediate housing 1 during installation, and to ensure that the side sealing component 2 can seal the side opening of the intermediate housing 1, positioning plates 12 are provided at both ends of the intermediate housing 1. The side sealing component 2 is provided with positioning grooves 24 corresponding to the positioning plates 12. The positioning plates 12 and positioning grooves 24 cooperate to restrict the position of the side sealing component 2 and the intermediate housing 1, thereby ensuring that the side sealing component 2 can be aligned and sealed with the openings at both ends of the intermediate housing 1 during installation. To ensure the sealing effect, sealing strips can be provided at the openings of the side sealing component 2 and the intermediate housing 1. To ensure the installation effect, mounting protrusions (existing technology, not shown in the figure) and threaded holes can be provided on the side sealing component 2 and the intermediate housing 1, and the two can be fixed by bolts to ensure the fixed installation effect.

[0021] Specifically, in order to ensure the normal sliding effect of the side sealing component 2, the bottom of the side sealing component 2 is provided with several sliding rollers 25, so that the side sealing component 2 can be pushed during use. The bottom of the positioning plate 12 is provided with obstacle avoidance grooves 13 corresponding to the sliding rollers 25. During installation, the sliding rollers 25 are slidably connected to the inside of the grooves, so that the sliding rollers 25 can abut and fit against both sides of the obstacle avoidance grooves 13, thereby limiting the lateral position of the side sealing component 2 during movement and further ensuring the positioning of the side sealing component 2.

[0022] In an exemplary embodiment, side limiting plates can be provided on both sides of the positioning insert plate 12, and side limiting grooves corresponding to the side limiting plates can be provided on both sides of the positioning groove 24.

The bottom of the positioning insert plate 12 is provided with a bottom plate, and the obstacle avoidance groove 13 is provided on the bottom plate.

[0023] Meanwhile, in order to ensure the support strength of the intermediate shell 1 and the side sealing component 2, the interior of the first filling space 14 and the second filling space 22 is provided with reinforcing ribs. The reinforcing ribs are used to seal the shells of the intermediate shell 1 and the side sealing component 2. The reinforcing ribs are provided with several evenly arranged ventilation holes 11 to ensure the heat dissipation and ventilation effect of the soundproof box. The reinforcing ribs on the intermediate shell 1 are provided with mounting holes 4, and the generator inlet and outlet are installed inside the mounting holes 4.

[0024] When using, please refer to Figures 1-5First, install the required generator into the bottom of the inner side of the intermediate housing 1 to fix the generator. Then, slide the side sealing parts 2 at both ends inward through the obstacle avoidance groove 13 and the positioning plate 12 to fill or insert the required noise reduction material into the corresponding filling space. Then, fix the side sealing parts 2 directly in the opening position. When maintenance is required, slide the side sealing parts 2 out by disassembling them to ensure space during maintenance. A double door 3 is provided on one side of the intermediate housing to ensure normal entry and exit and operation.
