Description

Technical Field

[0001] This utility model relates to the technical field of noise reduction equipment for energy storage cabinets, specifically to an integrated noise reduction component for energy storage cabinets. Background Technology

[0002] An energy storage cabinet is a device specifically designed to store electrical energy. Its core components include battery packs, inverters, and electronic devices such as control chips. Energy storage cabinets can provide both energy storage and power supply to charging stations.

[0003] Because the battery packs and other electronic devices in the energy storage cabinet are prone to overheating after prolonged operation, failure to dissipate this heat in a timely manner will lead to a decline in the cabinet's performance or even damage. In related technologies, to achieve heat dissipation in the energy storage cabinet, fans or air conditioners are typically installed inside. These fans or air conditioners remove the heat from inside the cabinet, thus achieving cooling. However, during the operation of fans or air conditioners, the airflow can generate significant noise, affecting the user experience of the energy storage cabinet. Furthermore, existing noise reduction devices are generally installed inside cabinets, which takes up cabinet space and may even obstruct internal components such as batteries, affecting the maintenance of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated noise reduction component for energy storage cabinets. By connecting the exhaust noise reduction pipe to the cabinet door, the exhaust noise reduction pipe will not affect the layout inside the cabinet, while the opening of the cabinet door facilitates maintenance of the cabinet interior.

[0005] This utility model provides the following technical solution: an integrated noise reduction component for an energy storage cabinet, including an exhaust noise reduction duct and a cabinet door. The exhaust noise reduction duct is connected to the cabinet door. The cabinet door includes an outer frame and a door frame. The outer frame is fixed to the energy storage cabinet body. The door frame is connected to the inner side of the outer frame via hinges. A crossbeam is connected to the middle of the door frame. A connection hole is formed between the upper end of the door frame and the crossbeam. A sealing plate is connected between the lower end of the door frame and the crossbeam. The connection hole communicates with the air inlet of the exhaust noise reduction duct. Multiple parallel sound-absorbing panels are installed inside the exhaust noise reduction duct. To further reduce noise and allow some sound waves to cancel each other out, the exhaust noise reduction duct is shaped like a figure 7. The air outlet is located on the side of the upper end of the figure 7, and the air inlet is located on the side of the lower end of the figure 7. An upper sound-absorbing plate is installed inside the air outlet, and a lower sound-absorbing plate is installed inside the air inlet.

[0006] To ensure the exhaust noise reduction duct is flush with the door frame and improve sealing, there is a gap between the upper end of the outer frame of the door and the upper end of the door frame. An installation beam is fixed to the side of the exhaust noise reduction duct, the installation beam is fixed within the gap, and the installation beam is connected to the upper end of the door frame.

[0007] In order to connect the mounting beam to the door frame, the two ends of the lower surface of the mounting beam are connected to the plug-in posts, and the upper ends of the two sides of the door frame are provided with plug holes, into which the plug-in posts are inserted.

[0008] To enhance the connection strength between the exhaust noise reduction duct and the door frame, angle steel is connected to both ends of the exhaust noise reduction duct, and the other end of the angle steel is connected to the door frame.

[0009] To facilitate air intake and prevent foreign objects from entering the cabinet, a filter plate is provided between the lower end of the sealing plate and the bottom edge of the door frame. The filter plate is the air intake side of the energy storage cabinet.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: by installing a noise-reducing exhaust duct on the upper part of the door frame, the sound-absorbing panel inside the noise-reducing exhaust duct reduces the noise during exhaust. At the same time, the noise-reducing exhaust duct is installed on the door frame, avoiding the noise-reducing exhaust duct occupying the volume inside the cabinet, and making it convenient to open the cabinet door for internal maintenance.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 and Figure 2This utility model provides a technical solution: an integrated noise reduction component for an energy storage cabinet, including an exhaust noise reduction duct 1 and a cabinet door 2. The exhaust noise reduction duct 1 is connected to the cabinet door 2. The cabinet door 2 includes an outer frame 21 and a door frame 22. The outer frame 21 is fixed to the energy storage cabinet body. One end of the door frame 22 is connected to the inner side of the outer frame 21 via a hinge. A crossbeam 26 is connected to the middle of the door frame 22. A connecting hole 23 is formed at the upper end of the door frame 21 and the crossbeam 26. A sealing plate 24 is connected between the lower end of the door frame 21 and the crossbeam 26. The connecting hole 23 is connected to the exhaust noise reduction duct 22. The air inlet of the noise reduction duct 1 is connected, and the exhaust noise reduction duct 1 is bolted to the door frame 22. Multiple parallel sound-absorbing panels are installed inside the exhaust noise reduction duct 1. The sound waves are absorbed by the multiple sound-absorbing panels, reducing the noise generated by the duct due to the impact and vibration of the airflow. The upper part of the exhaust noise reduction duct 1 is set at the upper end of the cabinet door 2. Setting the exhaust noise reduction duct 1 on the door frame 22 avoids the noise reduction equipment from occupying the space inside the cabinet. At the same time, the exhaust noise reduction duct 1 does not affect the opening of the cabinet door 2, making it convenient to open the cabinet door 2 and inspect the equipment inside the cabinet. like Figure 2 As shown, the exhaust noise reduction duct 1 is shaped like a figure 7. An air outlet is provided on the side of the upper end of the figure 7, and an air inlet is provided on the side of the lower end of the figure 7. An upper sound-absorbing plate 11 is provided inside the air outlet, and a lower sound-absorbing plate 12 is provided inside the air inlet. A mixing cavity is formed between the upper sound-absorbing plate 11 and the lower sound-absorbing plate 12, which merges the exhaust airflow and causes the sound waves generated by the airflow impact to converge in the mixing cavity. Some of the sound waves cancel each other out in the mixing cavity. At the same time, the upper sound-absorbing plate 11 and the lower sound-absorbing plate 12 successively reduce the noise of the passing airflow and absorb the sound waves to reduce noise.

[0014] like Figure 3 As shown, there is a gap between the upper end of the outer frame 21 and the upper end of the door frame 22. An installation beam 13 is fixed on the side of the exhaust noise reduction duct 1. The installation beam 13 is fixed in the gap and is connected to the upper end of the door frame 22. The installation beam 13 is flush with both the outer frame 2 and the door frame 22, and also makes the exhaust noise reduction duct 1 flush with the outer frame 21.

[0015] like Figure 3 As shown, the lower surface of the mounting beam 13 is fixed with plug-in posts 131 at both ends, and the upper ends of both sides of the door frame 22 have plug holes 221. The plug-in posts 131 are inserted into the plug holes 221, so that the mounting beam 13 is embedded in the gap between the outer door frame 21 and the door frame 22, further making the exhaust noise reduction duct 1 flush with the door frame 22, and improving the sealing between the exhaust noise reduction duct 1 and the door frame 22.

[0016] Angle steel 14 is bolted to both ends of the exhaust noise reduction duct 1, and the other end of the angle steel 14 is bolted to the door frame 22. The angle steel 14 is distributed on the lower end of the exhaust noise reduction duct 1, which increases the connection area between the exhaust noise reduction duct 1 and the door frame 22, improves the rigidity of the exhaust noise reduction duct 1, and reduces the vibration of the exhaust noise reduction duct 1.

[0017] A filter plate 25 is provided between the lower end of the sealing plate 24 and the bottom edge of the door frame 22. The filter plate 25 is the air inlet side of the energy storage cabinet. The filter plate 25 blocks the air inlet to prevent foreign objects from entering the cabinet.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
