Description

Technical Field

[0001] This application relates to the field of energy storage device technology, and in particular to a noise reduction device for energy storage containers. Background Technology

[0002] Energy storage containers are the basic energy storage units involved in energy storage projects. Their structure mainly includes a container body, a liquid cooling unit installed inside the container, and multiple battery packs. Air inlets and outlets are also provided on the container body corresponding to the location of the liquid cooling unit. During use, the liquid cooling unit draws in cold air from the outside through the air inlet into the container body. As the cold air flows through the container body, it mixes with the heat generated by the battery packs to form hot air, which is finally discharged from the air outlet. This achieves the circulation of cold air from the outside and hot air from the inside, thereby achieving the purpose of cooling the battery packs inside the container. At the same time, in existing technologies, silencers are usually installed on the outside of the container body corresponding to the air inlets and outlets to reduce the noise generated during the cooling process.

[0003] In practical applications, to ensure the noise reduction effect of the air inlet and outlet on the container, the existing noise reduction devices are generally adapted to the shape of the container, so that one noise reduction device can simultaneously reduce the noise of the air inlet and outlet. However, due to the large size and heavy weight of the existing noise reduction devices, in order to ensure the installation stability of the noise reduction devices, most existing technologies use bolts to fix the noise reduction devices directly to the container. In addition, when it is necessary to set up multiple energy storage containers in a designated area, in order to save site layout space, multiple energy storage containers are usually arranged in a rectangular array together, and adjacent energy storage containers are arranged symmetrically back to back, that is, the noise reduction devices on adjacent energy storage containers are close to each other.

[0004] However, for the above-mentioned usage scenarios, when maintenance is required on the liquid cooling unit inside the container, it is necessary to use tools such as forklifts to help workers remove the silencer and transport it away from the container. After the maintenance is completed, the silencer is then reinstalled on the outside of the container, making the overall maintenance process quite cumbersome. Furthermore, due to the limited space between two adjacent energy storage containers, the actual operation using tools is quite difficult.

[0005] Therefore, there is an urgent need for a noise reduction device that can ensure noise reduction while facilitating maintenance of liquid-cooled units by workers in situations where construction space is limited. Utility Model Content

[0006] To address the problem that existing silencers require repeated disassembly and reassembly during each maintenance of the liquid cooling unit inside the container, resulting in a cumbersome process, this application provides a silencer for energy storage containers.

[0007] This application provides a noise reduction device for energy storage containers, which adopts the following technical solution:

[0008] A noise reduction device for an energy storage container includes a support frame fixed to the container body, a base detachably connected to the support frame, and a noise reduction cover slidably disposed on the base. A sealing element is provided between the noise reduction cover and the container body. A first positioning structure for positioning the noise reduction cover is detachably disposed on the base. After the first positioning structure is removed and the noise reduction cover is slid away from the container body, a maintenance space is formed between the noise reduction cover and the container body.

[0009] By adopting the above technical solution, when the silencer is installed on the housing and the liquid cooling unit on the housing needs to be repaired, the worker only needs to remove the first positioning structure and pull the silencer cover to create a maintenance space between the silencer cover and the housing. The worker can then enter the maintenance space to repair the liquid cooling unit on the housing. After the maintenance is completed, the silencer cover is moved in the opposite direction to reset it. Then the first positioning structure is reinstalled on the base. The overall process is more convenient than the existing technology that requires repeated disassembly and reassembly of the silencer.

[0010] Preferably, one end of the base is slidably mounted on the support frame, and the other end of the base is provided with a support leg. The support leg supports the end of the base away from the support frame on the ground. One end of the support frame is provided with a first clamping plate, and the other end of the support frame is detachably provided with a second clamping plate. The first clamping plate and the second clamping plate clamp and limit the base on the support frame.

[0011] By adopting the above technical solution, the base and support frame can be detachably connected through the cooperation of the first clamp and the second clamp, and with the support bracket, the stability of the soundproof cover, base and support frame after installation is ensured.

[0012] Preferably, when an inspection space is formed between the soundproof cover and the housing, a reinforcing bolt is also provided between the base and the support frame. The reinforcing bolt is used to prevent the end of the base near the support frame from detaching from the support frame.

[0013] By adopting the above technical solution, when the silencer is moved away from the enclosure during use, the center of gravity shifts backward. At this time, the connection between the base and the support frame can be reinforced by strengthening bolts, thereby preventing the silencer from tilting at the connection between the support frame and the base when it is in a state away from the enclosure, which could indirectly cause the entire silencer to tip over.

[0014] Preferably, the silencer cover has an air inlet channel and an air outlet channel. The air inlet channel is provided with a first silencer structure, and the air outlet channel is provided with a second silencer structure. The air inlet channel is connected to the air inlet of the housing, and the air outlet channel is connected to the air outlet of the housing. The silencer cover is also provided with an air baffle plate, which separates the air inlet channel outlet end and the air outlet channel inlet end.

[0015] By adopting the above technical solution, the air baffle ensures that the flow of cold air in the air inlet channel and hot air in the air outlet channel will not interfere with each other. Combined with the first and second silencing structures, the silencing effect of the silencing cover is ensured.

[0016] Preferably, the first noise reduction structure includes a plurality of wave guide plates evenly distributed at intervals in the air inlet channel, and an air guide channel is formed between two adjacent wave guide plates. The wave guide plate includes a first bottom shell, a first cover plate fastened to the first bottom shell, and a first noise reduction cotton disposed between the first bottom shell and the first cover plate. Mesh holes are provided on both the first bottom shell and the first cover plate.

[0017] By adopting the above technical solution, when in use, the setting of several wave-shaped air guides guides the flow of external cold air, so that the cold air comes into contact with the first sound-absorbing cotton through the mesh during the flow, thereby converting sound energy into heat energy, thus achieving the effect of reducing noise.

[0018] Preferably, the inlet end of the air inlet channel and the outlet end of the air outlet channel are located on different sides of the silencer.

[0019] By adopting the above technical solution, when a large suction force is generated at the inlet end of the air inlet channel during the operation of the liquid chiller unit, the possibility of hot air discharged from the outlet end of the air outlet channel being re-inhaled into the air inlet channel, thereby causing the liquid chiller unit to shut down, is reduced, which is more conducive to ensuring the normal use of the liquid chiller unit.

[0020] Preferably, the end of the air baffle away from the housing is rotatably connected to the soundproof cover, the soundproof cover is provided with a first support plate, the air baffle is engaged with the first support plate, and the soundproof cover is also provided with a second positioning structure for positioning the air baffle after rotation.

[0021] By adopting the above technical solution, when in use, the rotating baffle plate, together with the first support plate and the second positioning structure, ensures that the baffle plate separates the outlet end of the air inlet channel from the inlet end of the air outlet channel. On the other hand, when workers are inspecting the liquid cooling unit, the baffle plate can be rotated open to reduce the impact of the baffle plate on the workers' inspection work, increase the inspection space, and make it easier for workers to work.

[0022] Preferably, the second positioning structure includes an abutment block fixed inside the soundproof cover and a strong magnet disposed on the abutment block, wherein the windproof plate is magnetically attracted to the strong magnet after rotation.

[0023] By adopting the above technical solution, the use of the abutment block and strong magnet ensures that the windbreak plate is positioned after rotation, making it more convenient to use.

[0024] Preferably, the first positioning structure includes a fixed plate detachably connected to the end of the base away from the support frame, and an adjusting bolt threadedly connected to the fixed plate, one end of the adjusting bolt passing through the fixed plate and engaging with the soundproof cover.

[0025] By adopting the above technical solution, during use, the muffler cover is brought into contact by turning the adjusting bolt, thereby ensuring the sealing effect of the sealing component on the gap between the enclosure and the muffler cover.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the silencer is installed on the housing, and maintenance of the liquid cooling unit on the housing is required, the worker only needs to remove the first positioning structure and pull the silencer cover to create maintenance space between the silencer cover and the housing. The worker can then enter the maintenance space to maintain the liquid cooling unit on the housing. After maintenance, the silencer cover is moved in the opposite direction to reset it. Then, the first positioning structure is reinstalled on the base. The overall process is more convenient than the existing technology that requires repeated disassembly and reassembly of the silencer.

[0028] 2. By reinforcing the bolts, the connection stability between the base and the support frame is strengthened during the maintenance of the liquid cooling unit, thereby reducing the likelihood of the silencer tipping over due to gravity when it is away from the housing.

[0029] 3. By setting up the baffle, on the one hand, it is ensured that the flow of cold air in the air inlet channel and hot air in the air outlet channel will not interfere with each other, thus ensuring the normal operation of the liquid cooling unit. On the other hand, when maintaining the liquid cooling unit, the baffle can be rotated and opened to reduce the impact of the baffle on the workers' maintenance work. Attached Figure Description

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will be described in further detail.

[0044] This application discloses a noise reduction device for energy storage containers.

[0045] Example 1:

[0046] Reference Figure 1 and Figure 2 A noise reduction device for an energy storage container includes a support frame 1, a base 2, and a noise reduction cover 3. One end of the support frame 1 is fixed to the container body by bolts, and the other end of the support frame 1 has an integrally formed vertical plate 13. A groove is formed between the vertical plate 13 and the outer wall of the container. In this application, the base 2 is a rectangular frame structure welded together from several square steels. The end of the base 2 near the container body is embedded in the groove, and the end of the base 2 away from the container body is suspended. Two sets of guide rails 21 are installed on the base 2. The two sets of guide rails 21 are spaced apart at both ends of the length direction of the base 2. The length direction of the guide rails 21 is parallel to the width direction of the base 2. A slide block 22 is slidably arranged on the guide rails 21. The bottom end of the noise reduction cover 3 is fixedly connected to the slide block 22. In this embodiment, a limiting plate 23 is also fixedly connected to the base 2. The limiting plate 23 abuts against the slide block 22.

[0047] Reference Figure 1 and Figure 2 In use, the silencing cover 3 slides on the base 2 through the cooperation of the slide block 22 and the slide rail. The maximum sliding distance of the slide block 22 is limited by the setting of the limiting plate 23, thereby limiting the maximum sliding distance of the silencing cover 3. During the transportation of the silencing device, in order to prevent the silencing cover 3 from sliding on the base 2, a positioning plate 24 is also set on the base 2. One end of the positioning plate 24 is fixed to the base 2 with bolts, and the other end of the positioning plate 24 is fixed to the silencing cover 3 with bolts. The setting of the positioning plate 24 avoids the relative sliding of the silencing cover 3 and the base 2 during the transportation of the silencing device, thereby ensuring the stability of the silencing device during transportation. After the transportation is completed and the silencing device is assembled with the box, the positioning plate 24 can be removed to avoid the positioning plate 24 affecting the subsequent operation of the sliding silencing cover 3.

[0048] Reference Figure 1 and Figure 2A first clamping plate 11 is bolted to one end of the support frame 1 along its length, and a second clamping plate 12 is bolted to the other end of the support frame 1 along its length. Through the cooperation of the first clamping plate 11 and the second clamping plate 12, the base 2 is clamped and limited on the support frame 1, thereby achieving the purpose of limiting the base 2 along the length of the support frame 1. Furthermore, through the cooperation of the vertical plate 13 and the outer wall of the box, the base 2 is limited along the width of the support frame 1.

[0049] Reference Figure 2 and Figure 3 In this embodiment, the bottom end of the first clamping plate 11 is fixed to the end face of the support frame 1 by bolts. The top end of the first clamping plate 11 is provided with a first slot 14, and the opening of the first slot 14 faces the base 2. A second slot 25 is provided at both ends of the base 2 along the length direction. The second slot 25 extends along the length direction of the base 2. When the base 2 and the support frame 1 are assembled together, the side wall of the first slot 14 and the side wall of the second slot 25 abut against each other. The bottom end of the second clamping plate 12 is fixed to the end face of the support frame 1 by bolts, and the top end of the second clamping plate 12 is fixed to the side wall of the base 2 by bolts.

[0050] Reference Figure 2 and Figure 3 In this application, when installing the base 2, the base 2 is first lifted by a forklift and then moved along the length of the support frame 1 until the base 2 is directly above the groove. Then the base 2 is lowered so that one end of the base 2 is embedded in the groove and the vertical plate 13 abuts against the inner side wall of the base 2. At this time, the top of the first clamping plate 11 is inserted into the second slot 25. Then the base 2 is moved along the length of the support frame 1 until the bottom wall of the first slot 14 abuts against the bottom wall of the second slot 25. The first slot 14 and the second slot 25 cooperate to form a locking limit on the base 2. Finally, the second clamping plate 12 is installed to connect the base 2 and the support frame 1. Thus, the first clamping plate 11 and the second clamping plate 12 can limit the length of the base 2.

[0051] Reference Figure 1 and Figure 4When the base 2, the soundproof cover 3, and the support frame 1 are connected, in order to prevent the end of the base 2 away from the support frame 1 from tilting downwards, a support frame 7 is also bolted to the end of the base 2 away from the support frame 1. The support frame 7 includes a foot cup 71 and a vertical rod 72 set at the top of the foot cup 71. The vertical rod 72 has several oblong holes 73, which are evenly distributed along the height direction of the vertical rod 72. The bolt passes through one set of oblong holes 73 and is threaded to the base 2. In use, by inserting the bolt into the oblong holes 73 at different height positions, the height of the support frame 7 can be adjusted by a large range. In conjunction with the height adjustment mechanism of the foot cup 71, the height of the support frame 7 can be adjusted by a small range, further ensuring the applicability of the device.

[0052] Reference Figure 5 and Figure 6 After the silencing device is installed on the housing, in order to ensure the silencing effect of the silencing device on the liquid cooling unit, a sealing element 4 is provided between the silencing cover 3 and the housing. In this embodiment, the sealing element 4 is preferably set as an elastic rubber ring. At the same time, a first positioning structure 5 is also provided on the base 2 at the end away from the housing. In use, the silencing cover 3 is positioned by the first positioning structure 5 to ensure that the silencing cover 3 is always in contact with the housing during use, and the sealing element 4 is in a compressed state, thereby sealing the connection gap between the silencing cover 3 and the housing through the sealing element 4.

[0053] Reference Figure 5 and Figure 6 The first positioning structure 5 includes a fixing plate 51 and an adjusting bolt 52. One end of the fixing plate 51 is fixed to the base 2 by bolts, and the adjusting bolt 52 is threaded to the other end of the fixing plate 51. One end of the adjusting bolt 52 passes through the fixing plate 51 and abuts against the side wall of the muffler 3. In use, by turning the adjusting bolt 52, the end of the adjusting bolt 52 is pressed against the muffler 3. Thus, the sealing element 4 is compressed by the abutment of the muffler 3 by the adjusting bolt 52, thereby ensuring the sealing effect of the sealing element 4.

[0054] Reference Figure 3 and Figure 7When the liquid cooling unit needs maintenance, simply remove the first positioning structure 5 and pull the silencer 3 away from the housing. When the slide 22 slides to abut against the limit plate 23, a maintenance space 6 is formed between the silencer 3 and the housing. At this time, the area on the housing where the liquid cooling unit is installed is exposed, and workers can enter the maintenance space 6 to maintain the liquid cooling unit. In addition, since the silencer 3 is relatively heavy, when the silencer 3 moves away from the housing, the center of gravity of the silencer 3 gradually moves away from the housing. In order to prevent the connection end between the base 2 and the support frame 1 from tilting during the sliding process of the silencer 3, which would cause the silencer 3 to tip over, a reinforcing bolt 8 is also provided between the base 2 and the support frame 1. Multiple reinforcing bolts 8 are provided and are evenly spaced along the length of the support frame 1. With the cooperation of multiple reinforcing bolts 8, it can be prevented that the end of the base 2 near the support frame 1 will detach from the support frame 1, causing the base 2 to tilt and thus causing the silencer 3 to tip over.

[0055] Reference Figure 5 and Figure 8 In this embodiment, the silencer 3 is configured as a rectangular box structure with one side open, and an air inlet channel 31 and an air outlet channel 32 are formed on the silencer 3. The air inlet channel 31 is connected to the air inlet of the box through the inner cavity of the silencer 3, and the air outlet channel 32 is connected to the air outlet of the box through the inner cavity of the silencer 3. An air baffle 35 is rotatably arranged on the inner wall of the silencer 3. The air baffle 35 is initially set horizontally, and at this time the air baffle 35 separates the outlet end of the air inlet channel 31 and the inlet end of the air outlet channel 32, thereby ensuring that the cold air in the air inlet channel 31 flows to the air inlet of the box, and the hot air discharged from the air outlet of the box is discharged from the air outlet channel 32, so as to avoid the cold air at the outlet end of the air inlet channel 31 and the hot air at the inlet end of the air outlet channel 32 from mixing and causing the hot air to flow back into the air inlet of the box.

[0056] Reference Figure 5 and Figure 8 Furthermore, in actual use, when the distance between two adjacent energy storage containers is small, suction will be generated at the air inlet channel 31 during the operation of the liquid cooling unit, thereby drawing in cold air from the outside into the air inlet channel 31. At the same time, hot air in the container is discharged from the air outlet channel 32. In order to prevent the hot air discharged from the air outlet channel 32 from being drawn back into the air inlet channel 31 due to the suction in the area of ​​the air inlet channel 31, which would cause the liquid cooling unit to shut down, in this embodiment, the inlet end of the air inlet channel 31 is located on the side of the silencer 3 away from the container, and the outlet end of the air outlet channel 32 is located on the top side of the silencer 3.

[0057] Reference Figure 8 and Figure 9The first support plate 9 is fixed to the inner wall of the silencer 3 by bolts. The right end of the baffle plate 35 is hinged to the inner wall of the silencer 3. When the baffle plate 35 is in a horizontal state, the left end of the baffle plate 35 overlaps the first support plate 9, and the baffle plate 35 is snapped to the first support plate 9 by bolts. The inner wall of the silencer 3 is also provided with a second positioning structure 36. When it is necessary to maintain the liquid cooling unit, the silencer 3 is pulled to create a maintenance space 6 between the silencer 3 and the housing. The worker can rotate the baffle plate 35 upward to bring it close to the second positioning structure 36, thereby snapping and fixing the baffle plate 35 through the second positioning structure 36. This reduces the impact of the baffle plate 35 on the worker's maintenance work and increases the size of the maintenance space 6.

[0058] Reference Figure 1 and Figure 8 The second positioning structure 36 includes an abutment block 361 and a strong magnet 362. The abutment block 361 is fixed to the inner wall of the soundproof cover 3 by bolts. In this embodiment, the abutment block 361 is inclined on the side facing the wind baffle 35, and the strong magnet 362 is installed on the inclined surface of the abutment block 361. After the wind baffle 35 rotates, it can be attracted to the abutment block 361 by the strong magnet 362. In order to improve the magnetic attraction stability of the wind baffle 35, the wind baffle 35 needs to rotate at an angle greater than 90 degrees before abutting with the abutment block 361. In this application, the rotation angle of the wind baffle 35 is 93 degrees. With the setting of the strong magnet 362, the wind baffle 35 can be easily and quickly snapped into place. After maintenance, the worker only needs to pull the wind baffle 35 to make it disengage from the strong magnet 362 and rotate it back to abut against the first support plate 9.

[0059] Reference Figure 8 and Figure 10 To ensure the noise reduction effect of the silencer 3, a first noise reduction structure 33 is provided in the air inlet channel 31. The first noise reduction structure 33 includes several wave-shaped air guide plates 331. The wave-shaped air guide plates 331 are evenly distributed along the height direction of the silencer 3, and a wave-shaped air guide channel 332 is formed between two adjacent wave-shaped air guide plates 331. Each first noise reduction structure 33 includes a first bottom shell 3311, a first cover plate 3312, and a first noise reduction cotton 3313. A noise reduction cavity is formed on the first bottom shell 3311. The first noise reduction cotton 3313 is filled in the noise reduction cavity. The first cover plate 3312 is used to seal the noise reduction cavity. In this application, the outer wall surface of the first cover plate 3312 and the first bottom shell 3311 are provided with mesh holes.

[0060] Reference Figure 8 and Figure 10In use, cold air is drawn in from the inlet end of the air inlet channel 31. Part of the cold air, guided by the wave guide plate 331, passes through the mesh on the first cover plate 3312 or the first bottom shell 3311 and comes into contact with the first sound-absorbing cotton 3313 in the sound-absorbing cavity. The sound energy is converted into heat energy by the first sound-absorbing cotton 3313, thereby achieving the purpose of canceling noise. The other part, guided by the air guide channel 332, continuously impacts the first cover plate 3312 or the first bottom shell 3311. Finally, the noise is partially canceled by contact with the first sound-absorbing cotton 3313 at different angles, thereby achieving the purpose of reducing noise during the flow of cold air through the air inlet channel 31.

[0061] Reference Figure 8 and Figure 10 The first silencing structure 33 has a second support plate 10 on its bottom side and a third support plate 20 on its top side. Both the second support plate 10 and the third support plate 20 are fixed to the inner wall of the silencing cover 3 by bolts, and the second support plate 10 and the third support plate 20 clamp and fix the first silencing structure 33 inside the silencing cover 3. In use, first install and fix the second support plate 10 to the inner wall of the silencing cover 3, then place the first silencing structure 33 on the second support plate 10, and then move the third support plate 20 so that the third support plate 20 presses the first silencing structure 33 tightly onto the second support plate 10. Then fix the third support plate 20. This completes the installation of one set of first silencing structures 33. Repeating the above steps can realize the installation of multiple sets of first silencing structures 33 one by one inside the silencing cover 3.

[0062] Reference Figure 8 and Figure 11 A second silencing structure 34 is provided in the air outlet duct 32. The second silencing structure 34 includes a first silencing plate 341 placed horizontally and a second silencing plate 342 placed vertically. In this application, several sets of the second silencing structure 34 are provided. The several sets of the second silencing structure 34 have different sizes. The several sets of the second silencing structure 34 cooperate to form an L-shaped flow channel, so that hot air enters the air outlet duct 32 from the horizontal direction and is finally discharged from the outlet end of the air outlet duct 32 at the top.

[0063] Reference Figure 8 and Figure 11 The first sound-absorbing plate 341 and the second sound-absorbing plate 342 have the same layer structure and connection method. Taking the first sound-absorbing plate 341 as an example, the first sound-absorbing plate 341 includes a second bottom shell 3411, a second cover 3412 and a second sound-absorbing cotton 3413. The second sound-absorbing cotton 3413 is located between the second bottom shell 3411 and the second cover 3412. Multiple through holes are also provided on the second bottom shell 3411 and the second cover 3412. In use, the noise in the air outlet duct 32 is reduced by the cooperation of the through holes and the second sound-absorbing cotton 3413.

[0064] Reference Figure 8 and Figure 11 A fourth support plate 30 is provided on the bottom side of the first silencing plate 341, and a fifth support plate 40 is provided on the upper side of the first silencing plate 341. The fourth support plate 30 and the fifth support plate 40 form a clamping and fixing mechanism for the first silencing plate 341. A sixth support plate 50 is provided on the right side of the second silencing plate 342, and a seventh support plate 60 is provided on the left side of the second silencing plate 342. The sixth support plate 50 and the seventh support plate 60 form a clamping and fixing mechanism for the second silencing plate 342. During installation, the fourth support plate 30 is first fixed to the inner wall of the silencing cover 3, and then the first silencing plate 341 is... Place the fifth support plate 40 on the fourth support plate 30, and then attach the fifth support plate 40 to the upper side wall of the first silencing plate 341 to complete the installation of the first silencing plate 341. Then, install and fix the sixth support plate 50, and then slide the second silencing plate 342 laterally to abut against the sixth support plate 50. At this time, the bottom end of the second silencing plate 342 abuts against the top end of the first silencing plate 341. Finally, move the seventh support plate 60 to abut against the second silencing plate 342 and fix it to complete the installation of the second silencing plate 342, thereby completing the assembly of a set of second silencing structures 34.

[0065] Reference Figure 8 In this embodiment, a third layer of sound-absorbing cotton is provided on the inner side wall of the soundproof cover 3. The first sound-absorbing cotton 3313, the second sound-absorbing cotton 3413 and the third sound-absorbing cotton are preferably made of aluminum silicate ceramic cotton. When in use, the sound-absorbing effect of the soundproof cover 3 is ensured by the combined use of the first sound-absorbing cotton 3313, the second sound-absorbing cotton 3413 and the third sound-absorbing cotton.

[0066] Reference Figure 1 The silencer 3 has a forklift hole 70 and a lifting ring is welded and fixed to the top of the silencer 3. When in use, the forklift hole 70 makes it easy for workers to transport the silencer 3 by forklift, and the lifting ring allows the entire silencer device to be transported by crane, adapting to different installation and transportation needs.

[0067] The implementation principle of this application embodiment is as follows: In use, the worker first installs the entire silencer on the housing using a transport vehicle, and installs the support bracket 7 and the first positioning structure 5. The positioning plate 24 is then removed. When the liquid-cooled unit needs to be repaired, only the first positioning structure 5 needs to be removed. Then, the silencer cover 3 is pulled away from the housing, and reinforcing bolts 8 are installed between the base 2 and the support frame 1 to ensure the stability of the connection between the silencer cover 3, the base 2, and the support frame 1. When the silencer cover 3 and the housing form a maintenance space 6, the worker can enter the maintenance space 6 and rotate the baffle plate 35 upward to increase the size of the maintenance space 6. After that, the maintenance operation can be carried out. After the maintenance is completed, the baffle plate 35 is rotated back to its original position, and then the worker exits the maintenance space 6. Finally, the silencer cover 3 is restored to its original position, and the first positioning structure 5 is reinstalled on the base 2. This completes the maintenance operation of the liquid-cooled unit. The overall use is simple and convenient, and there is no need to repeatedly disassemble the entire silencer.

[0068] Example 2:

[0069] Reference Figure 12 The difference between this embodiment and Embodiment 1 is that this embodiment provides a method for using a noise reduction device for an energy storage container, the steps of which are as follows:

[0070] S1. Install the muffler on the housing and remove the positioning plate 24: Before installing the muffler on the housing for the first time, the support frame 1 needs to be fixed to the housing with bolts, and the second clamping plate 12 needs to be fixed with bolts at the end of the support frame 1 with a smaller working space. Then, the muffler cover 3 and the base 2 are placed on the support frame 1 by a forklift, and the base 2 and the muffler cover 3 are pushed along the length of the support frame 1 until the bottom wall of the first slot 14 abuts against the bottom wall of the second slot 25. Then, the first clamping plate 11 is fixed to the other end of the support frame 1 to limit the base 2 in the length of the support frame 1. Finally, the positioning plate 24 is removed.

[0071] S2. Assemble the support frame 7 and the first positioning structure 5: Bolt the support frame 7 together with the base 2 at the end away from the box, and install the first positioning structure 5 at the end of the base 2 away from the support frame 1, so as to fix the silencer 3 and compress the seal 4, thereby sealing the connection gap between the silencer 3 and the box through the seal 4, thus completing the installation of the silencer device.

[0072] S3. Before maintenance, remove the first positioning structure 5 and strengthen the connection between the base 2 and the support frame 1. When maintenance is required, first remove the first positioning structure 5 from the base 2, and then have the workers pull the silencer 3 away from the enclosure. When there is an appropriate distance between the silencer 3 and the enclosure, the workers will drive several reinforcing bolts 8 into the base 2 and the support frame 1 one by one, thereby strengthening the connection between the base 2 and the support frame 1 through the reinforcing bolts 8.

[0073] S4. Pull the silencer cover 3 and the worker enters the maintenance space 6 to carry out maintenance work: Continue to pull the silencer cover 3 away from the box until the maintenance space 6 is formed between the silencer cover 3 and the box. The worker can then enter the maintenance space 6 and rotate the baffle plate 35 to abut against the abutting block 361. Then, the baffle plate 35 is attracted to the abutting block 361 by the strong magnet 362. After that, the liquid cooling unit on the box can be maintained.

[0074] S5. Restore the silencer 3 to its original state: After the maintenance is completed, the staff will first rotate the wind baffle 35 to abut the first support plate 9 and re-clamp it securely. Then the staff will leave the maintenance space 6 and push the silencer 3 towards the direction of the enclosure until the seal 4 on the silencer 3 abuts the enclosure.

[0075] S6. Reinstall the first positioning structure 5: Finally, reinstall the first positioning structure 5 onto the base 2, and use the first positioning structure 5 to press the muffler 3 against the base, so that the seal 4 re-seals the connection gap between the muffler 3 and the housing, thus completing the entire maintenance process.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
