Description

Technical Field

[0001] This invention belongs to the field of noise reduction equipment technology, specifically relating to a modular noise reduction board and a combined noise reduction device for energy storage cabinets. Background Technology

[0002] Because energy storage systems contain equipment such as batteries, PCS, high-voltage boxes, and liquid cooling units, these devices generate noise during operation; in particular, the noise generated by the PCS is extremely high. For energy storage devices located in residential areas, the noise has seriously affected the lives of residents. Therefore, there is an urgent need for a device that can reduce noise.

[0003] Existing technologies reduce noise by changing the material of the board and covering the noisy equipment. While this reduces noise to some extent, the noise reduction devices used all require the separate manufacture of various specifications of boards for specific equipment. They do not adopt a modular design, which makes it inconvenient to assemble quickly on-site and difficult to adapt to different application scenarios. Summary of the Invention

[0004] The purpose of this invention is to overcome the existing defects and provide a modular noise reduction board and a combined noise reduction device for energy storage cabinets.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The first objective of this invention is to provide a modular noise reduction board, comprising a noise reduction board base plate, a noise reduction board panel, and a noise reduction rock wool layer; The noise reduction board panel and the noise reduction board base plate are connected by multiple stainless steel pipes. A reserved cavity is provided between the noise reduction board panel and the noise reduction board base plate, and a noise reduction rock wool layer is provided in the reserved cavity. The noise reduction panel has an array of louvered openings, which are configured to allow sound to be transmitted to the internal noise reduction rock wool layer.

[0006] Furthermore, the noise reduction panel has positioning and mounting holes on its upper and lower sides for alignment and installation during assembly.

[0007] Furthermore, each end of the outer surface of the noise reduction panel is fixed with an installation handle for handling and stacking installation.

[0008] Another objective of the present invention is to provide a combined noise reduction device for an energy storage cabinet, comprising a semi-enclosed noise reduction wall structure and a viewing window. The semi-enclosed noise reduction wall structure includes a front noise reduction wall and a side noise reduction wall. The front noise reduction wall is connected to a side noise reduction wall on each side by a hinge sheet metal, and the installation angle between the front noise reduction wall and the side noise reduction wall is adjusted by the hinge sheet metal. Both the front noise reduction wall and the side noise reduction wall include multiple modular noise reduction panels provided by the first objective of this invention, which are stacked and assembled vertically. The visual observation window is located on the front noise reduction wall at the position corresponding to the indicator light of the energy storage cabinet, and is used to observe the operating status of the energy storage cabinet.

[0009] Furthermore, the viewing window has a three-layer structure, including a viewing window base plate, a transparent acrylic plate, and a viewing window panel; The transparent acrylic sheet is installed on the bottom plate of the viewing window by press-fit screws and nuts; The viewing window panel is installed on the viewing window base plate, and the viewing window panel and the viewing window base plate are connected by a stainless steel pipe. The viewing window panel is provided with positioning and mounting holes for alignment and installation during assembly.

[0010] Furthermore, both the front noise reduction wall and the side noise reduction wall are provided with a flat base and a triangular mounting base at the bottom. The flat base is located at one end of the bottom of the lowest modular noise reduction plate, and the flat base has bolt holes in the middle for fixing the overall structure. The triangular mounting bracket clamps and fixes the lowest modular noise reduction plate to the flat base, and locks it in place by passing long screws through the stainless steel tube of the modular noise reduction plate.

[0011] Furthermore, positioning pins are installed between adjacent modular noise reduction panels and between the modular noise reduction panels and the viewing window, with the positioning pins passing through the middle of the positioning mounting holes.

[0012] Furthermore, multiple edge-sealing sheet metals are installed on both sides of the front noise reduction wall and on the side of the side noise reduction wall near the front noise reduction wall. Multiple C-shaped snap-fit ​​sheet metals are installed on the outer side of the side noise reduction wall. The edge-sealing sheet metals and the C-shaped snap-fit ​​sheet metals are fixed and locked to the stainless steel pipes by long screws.

[0013] Furthermore, a curved sheet metal is installed on the upper side of the front noise reduction wall, and the curved sheet metal is fixed and locked to the stainless steel pipe by long screws.

[0014] In combination with the above technical solutions, the beneficial effects of the present invention compared with the prior art are as follows: This invention proposes a sound-absorbing and noise-reducing panel with louvers, which can adapt to outdoor working environments. The sound-absorbing and noise-reducing panel adopts a modular combination method, and the height of the noise-reducing wall can be flexibly set according to the height of the equipment. A viewing window is also provided on the noise-reducing wall to facilitate observation of the system's operating status from behind the wall. The viewing angle is taken into account to avoid the problem that the opening is too small, which would restrict the viewing of indicator lights to a fixed angle.

[0015] This invention achieves noise reduction by directly covering the noise source. It proposes a modular design for constructing multi-faceted noise-reducing walls, featuring a semi-enclosed system cabinet structure that is lightweight and disassembleable. This allows for flexible and convenient on-site assembly, supports transportation, and facilitates rapid on-site assembly, adapting to various application scenarios. After installation, the soundproof wall can withstand average wind speeds of level 8 and gusts of level 9. Attached Figure Description

[0022] Example 2:

[0023] Combination Figure 2 As shown, this embodiment provides a combined noise reduction device for energy storage cabinets, including a front noise reduction wall 20 and a side noise reduction wall 21 with a semi-enclosed structure installation. The front noise reduction wall 20 is connected to a side noise reduction wall 21 on both sides by hinge sheet metal 16, and the installation angle between the front noise reduction wall 20 and the side noise reduction wall 21 is adjusted by the hinge sheet metal 16. Both the front noise reduction wall 20 and the side noise reduction wall 21 include multiple modular noise reduction panels provided in Embodiment 1 that are stacked and assembled vertically. A visual observation window 22 is provided at the corresponding position of the noise reduction wall 20 and the indicator light of the energy storage cabinet, which makes it easy for operation and maintenance personnel to observe the operating status of the energy storage cabinet.

[0024] Combination Figure 3 As shown, both the front noise reduction wall 20 and the side noise reduction wall 21 include a flat base 11, a triangular mounting base 12, a long screw 13, a positioning pin 14, an edge-sealing sheet metal 15, a hinge sheet metal 16, a C-shaped clamping sheet metal 18, and an expansion screw 19.

[0025] The flat base 11 is placed directly in front of the energy storage cabinet. The side of the noise reduction plate with louver holes 4 faces the energy storage cabinet. The noise reduction plate is installed on the flat base 11. The noise reduction plate is clamped in the middle using a triangular mounting bracket 12. The long screw 13 passes through the stainless steel pipe 6 for fixing and locking. Thus, the construction of the bottom layer of noise reduction wall is completed.

[0026] For the construction of the upper noise reduction wall, first screw the positioning pin 14 into the positioning mounting hole 7 on the upper part of the noise reduction board, and then use the installation handle 3 to stack the noise reduction boards to the upper modular layer in sequence. Use the edge-wrapping sheet metal 15 and hinge sheet metal 16 to clamp the noise reduction board between the two, and fix and lock it by passing the long screw 13 through the stainless steel pipe 6.

[0027] The side noise reduction wall 21 is connected to the front noise reduction wall 20 via hinged sheet metal 16 and is secured by long screws 13 passing through the stainless steel pipe 6. C-shaped clip-on sheet metal 18 is installed on the outer end of the side noise reduction wall 21 for further fixation.

[0028] The installation angle between the side noise reduction wall 21 and the front noise reduction wall 20 can be adjusted using the hinge sheet metal 16, allowing for flexible adjustment of the installation position based on surrounding building obstructions.

[0029] As a preferred option, curved sheet metal 17 is fixed to the upper part of both sides of the viewing window 22, and the noise reduction plate is then installed using the curved sheet metal 17, and fixed and locked by long screws 13 passing through the stainless steel pipe 6.

[0030] Combination Figure 4 As shown, the viewing window 22 has a three-layer structure, including the viewing window base plate 8, the transparent acrylic plate 9, and the viewing window panel 10. The transparent acrylic plate 9 is installed on the bottom plate 8 of the viewing window by pressing screws and nuts; The viewing window panel 10 is installed on the viewing window bottom plate 8, and the viewing window panel 10 and the viewing window bottom plate 8 are connected by a stainless steel pipe 6. The visual observation window panel 10 is provided with positioning mounting holes 7 for alignment and installation during assembly.

[0031] In use, after adjusting the installation angle between the noise reduction wall and the energy storage cabinet, a hole is drilled in the ground using an impact drill, and expansion screws 19 are inserted into the flat base 11 and driven into the ground for fixation. Figure 5 As shown, due to the modular design of this embodiment, the number of noise reduction walls can be expanded laterally according to the number of energy storage cabinets to achieve an overall noise reduction effect.
