Description

Technical Field

[0001] This invention relates to the field of energy storage cabinets, and more particularly to a multi-layered, containerized energy storage cabinet with a limiting mechanism. Background Technology

[0002] An energy storage cabinet is an integrated device for storing and releasing electrical energy. Due to its large-scale energy storage characteristics, it is known as a "super power bank". A single energy storage cabinet can store up to 5,500 kWh of electricity per day, which is equivalent to the daily electricity demand of more than 500 households. The energy storage cabinet realizes the storage and release of electrical energy through core components such as battery modules, battery management system (BMS), and thermal management system. Its application scenarios cover the generation side, grid side, user side and household side, and it plays the role of "power bank" in the new power system.

[0003] Containerized energy storage units are highly integrated energy storage systems developed to meet the needs of the mobile energy storage market. They integrate lithium battery packs, BMS, PCS, EMS, and auxiliary systems such as temperature control and fire protection into a standard container (usually 20 feet or 40 feet), forming a mobile, independent energy storage unit that can be connected to the grid upon arrival.

[0004] In existing technologies, containerized energy storage cabinets typically have two functional zones: a battery compartment and an equipment compartment. The battery compartment lacks multi-layered partition and limiting mechanisms. Containerized energy storage cabinets need to be transported long distances by road, rail, and sea. During the journey, they inevitably encounter conditions such as bumps, sudden braking, centrifugal force from turns, and the impact of ocean waves. Under these conditions, the battery modules are prone to impacting the cabinet walls, causing shell deformation, cell compression, and loosening of electrical connectors, resulting in poor contact and reducing the operational stability of the containerized energy storage cabinet.

[0005] Therefore, it is necessary to provide a multi-layered, compartmentalized energy storage cabinet with a limiting mechanism to solve the above-mentioned technical problems. Summary of the Invention

The water after heat exchange can be collected through second hoses into the inside of the distribution plate and re-enter the inner cavity of the serpentine tube for cooling. This circulating cooling water flow into the hollow pressure plate further reduces the operating temperature of the battery pack and extends its service life. Attached Figure Description

Figure 3 for Figure 1 The diagram shows the structure of the second motor and the transmission box. Figure 4 for Figure 1 The diagram shows a frontal sectional view of the structure.

Figure 7 for Figure 1 The diagram shows the structure of the threaded rod and threaded sleeve. Figure 8 for Figure 1The diagram shows the structure of the second fixed box and the second fan. The multi-layered, compartmentalized energy storage cabinet with a limiting mechanism includes an energy storage cabinet body 1. A battery cavity 2 is opened on one side of the inner cavity of the energy storage cabinet body 1. A fixed frame 3 is fixedly connected to the other side of the inner cavity of the battery cavity 2. A movable frame 4 that moves horizontally is provided on one side of the inner cavity of the battery cavity 2. L-shaped bearing plates 6 are fixedly connected to the opposite surfaces of the movable frame 4 and the fixed frame 3.

[0022] When the movable frame 4 moves, it drives the L-shaped support plate 6 on its surface to move toward the L-shaped support plate 6 on the fixed frame 3. This is used to adjust the distance between the two movable frames 4 to adapt to different specifications of battery packs and limit their horizontal movement. The inner cavity of the battery cavity 2 is provided with several hollow pressure plates 26 that move vertically.

[0023] The hollow pressure plate 26 is located above the corresponding two L-shaped support plates 6. After the battery pack is placed on the surface of the corresponding two L-shaped support plates 6, the hollow pressure plate 26 descends to contact the top of the battery pack and limits the vertical direction of the battery pack.

[0024] On the other side of the inner cavity of the energy storage cabinet body 1, there is an equipment cavity 14. The inner cavity of the equipment cavity 14 is equipped with a cooling mechanism that circulates water into the hollow pressure plate 26. An electrical control component 15 is provided at the bottom of the inner wall of the equipment cavity 14.

[0025] After the battery pack is placed on the surfaces of the two corresponding L-shaped support plates 6, it can be moved by the movable frame 4. The movable frame 4 moves the L-shaped support plate 6 on its surface closer to the upper L-shaped support plate 6 on the surface of the fixed frame 3, thereby clamping the two sides of the battery pack for horizontal positioning.

[0026] After horizontal limiting, the hollow pressure plate 26 descends, and the lower surface of the hollow pressure plate 26 abuts against the top of the battery pack, thereby limiting the vertical direction of the battery pack, improving the stability of the battery pack placed in the inner cavity of the battery cavity 2, improving the protection of the battery pack, and thus improving the safety of the energy storage cabinet body 1 during operation.

[0027] A drive box 7 is fixedly connected to one side of the energy storage cabinet body 1. A first motor 8 is fixedly connected to the top of the drive box 7. A gear shaft 9 is rotatably installed inside the drive box 7. The top of the gear shaft 9 extends to the outside of the drive box 7 and is fixedly connected to the output shaft of the first motor 8.

[0028] The inner cavity of the drive box 7 is provided with several rack plates 10 that move in the horizontal direction, and the rack plates 10 mesh with the gear shaft 9.

[0029] A push-pull plate 13 is fixedly connected to the side wall of the rack plate 10. The other end of the push-pull plate 13 is pulled out and extended into the inner cavity of the battery cavity 2, and is fixedly connected to one side of the movable frame 4.

[0030] After the first motor 8 starts working, it can drive the gear shaft 9 to rotate. Through the transmission of the rack plate 10, the moving frame 4 can be pushed and pulled in the inner cavity of the battery cavity 2 by the push-pull plate 13 to move horizontally.

[0031] Guide rails 5 are horizontally fixedly connected to the top and bottom of the inner wall of the battery cavity 2, and limiting blocks that are slidably sleeved on the surface of the corresponding guide rails 5 are fixedly connected to the top and bottom of the movable frame 4.

[0032] A crossbar 11 is fixedly connected to the inner cavity of the drive box 7, and a guide block 12 is fixedly connected to the side wall of the rack plate 10 and slidably sleeved on the surface of the crossbar 11.

[0033] A transmission box 22 is fixedly connected to the rear end face of the energy storage cabinet body 1. Several threaded rods 23 are rotatably arranged inside the transmission box 22, and the multiple threaded rods 23 correspond one-to-one with multiple hollow pressure plates 26.

[0034] The threaded rod 23 is threadedly connected to a threaded sleeve 24. A connecting block 27 is fixedly connected to the front side of the threaded sleeve 24. The front end of the connecting block 27 extends movably into the inner cavity of the battery cavity 2 and is fixedly connected to the side wall of the corresponding hollow pressure plate 26.

[0035] A second motor 28 is fixedly connected to the bottom of the side wall of the transmission box 22. The output shaft of the second motor 28 extends rotatably into the inner cavity of the transmission box 22 and is fixedly connected to a first bevel gear 29.

[0036] The bottom end of the threaded rod 23 at the bottom is fixedly connected to a second bevel gear 30 that meshes with the first bevel gear 29. The front side of the transmission box 22 and the rear end of the inner wall of the battery cavity 2 are both vertically provided with guide ports 25 for limiting the movement of the connecting block 27.

[0037] After the second motor 28 starts working, it can drive the first bevel gear 29 to rotate. After the second bevel gear 30 rotates, it can simultaneously drive multiple threaded rods 23 to rotate. After the threaded sleeve 24 moves along the surface of the threaded rod 23, it can drive the hollow pressure plate 26 to move up and down through the connecting block 27.

[0038] The other end of the front side of the energy storage cabinet body 1 is detached and installed with a maintenance cover 17 corresponding to the equipment cavity 14 by several bolts 16. The front side of the maintenance cover 17 is connected to the first fixed box 18.

[0039] The inner cavity of the first fixed box 18 is provided with several first fans 19, the front side of the first fixed box 18 is provided with a first air inlet 20, and the other side of the energy storage cabinet body 1 is provided with a first exhaust vent 21 that communicates with the inner cavity of the equipment cavity 14.

[0040] After the first fan 19 starts working, it can draw in external airflow through the first air inlet 20 and inject it into the inner cavity of the equipment cavity 14 to dissipate heat from the electronic control components 15. The airflow carrying heat is discharged through the first exhaust 21.

[0041] The cooling mechanism includes a cooling chamber 38, a circulating pump body 31, and a serpentine tube 37. The cooling chamber 38 is fixedly connected to the top of the other side of the energy storage cabinet body 1, the serpentine tube 37 is fixedly connected to the inner cavity of the cooling chamber 38, and the circulating pump body 31 is fixedly connected to the top of the inner cavity of the equipment chamber 14.

[0042] The inlet of the circulating pump body 31 is connected to one end of the serpentine tube 37, and a diverter plate 32 is fixedly connected to the other side of the inner wall of the battery cavity 2. The top of the hollow pressure plate 26 is connected to the diverter plate 32 through the first flexible hose 34.

[0043] A collection plate 36 is fixedly connected to the other side of the inner wall of the equipment cavity 14. The upper surface of the hollow pressure plate 26 is connected to the collection plate 36 through the second flexible hose 35, and the other end of the serpentine tube 37 is connected to the collection plate 36.

[0044] After the circulating pump body 31 starts working, it can draw water from inside the serpentine tube 37 and inject it into the inner cavity of the diversion plate 32 through the water injection pipe 33. After being diverted through multiple first hoses 34, it is injected into the inner cavity of the hollow pressure plate 26, which can exchange heat for the battery pack during operation and reduce the temperature of the battery pack during operation.

[0045] After heat exchange, the water flow can be collected through the second hose 35 into the inside of the collector plate 36, and then re-enter the inner cavity of the serpentine tube 37 for cooling. This circulates cooling water into the inside of the hollow pressure plate 26, thereby reducing the operating temperature of the battery pack and extending its service life.

[0046] The rear side of the cooling chamber 38 is connected to the second fixed box 39. The inner cavity of the second fixed box 39 is equipped with a second fan 40. The rear end of the second fixed box 39 is equipped with a second air inlet 41. The front side of the cooling chamber 38 is equipped with a second exhaust 42.

[0047] After the second fan 40 starts working, it draws in external airflow through the second air inlet 41 and injects it into the inner cavity of the cooling chamber 38 to cool the water flow in the serpentine tube 37. The airflow carrying heat can then be discharged through the second exhaust 42.

[0048] The front end of the energy storage cabinet body 1 is provided with a cabinet door 43 that is adapted to the battery cavity 2, and the cabinet door 43 is provided with a control panel and a latch.

[0049] The working principle of the multi-layered, compartmentalized energy storage cabinet with limiting mechanism provided by this invention is as follows: After opening the cabinet door 43, the battery cavity 2 is exposed, and the battery pack can be placed on the surfaces of the corresponding two L-shaped support plates 6. After the first motor 8 starts working, it can drive the gear shaft 9 to rotate. Through the transmission of the rack plate 10, the sliding frame 4 can be pushed and pulled horizontally in the inner cavity of the battery cavity 2 via the push-pull plate 13. As the sliding frame 4 moves, the L-shaped support plate 6 on its surface moves closer to the upper L-shaped support plate 6 on the surface of the fixed frame 3. The battery pack can be clamped on both sides for horizontal positioning. After horizontal positioning, the second motor 28 drives the first bevel gear 29 to rotate. After the second bevel gear 30 rotates, it can simultaneously drive multiple threaded rods 23 to rotate. After the threaded sleeve 24 moves along the surface of the threaded rod 23, it can drive the hollow pressure plate 26 to move up and down through the connecting block 27. After the hollow pressure plate 26 descends, the lower surface of the hollow pressure plate 26 abuts against the top of the battery pack, thus positioning the battery pack vertically.

[0050] Compared with related technologies, the multi-layered, compartmented energy storage cabinet with limiting mechanism provided by the present invention has the following advantages: After the battery pack is placed on the surfaces of the two corresponding L-shaped support plates 6, it can be moved by the movable frame 4. The movable frame 4 moves the L-shaped support plates 6 on its surface closer to the upper L-shaped support plates 6 on the surface of the fixed frame 3, thereby clamping the two sides of the battery pack for horizontal limitation. After limitation, the hollow pressure plate 26 descends, and the lower surface of the hollow pressure plate 26 abuts against the top of the battery pack, thereby limiting the vertical direction of the battery pack. This improves the stability of the battery pack placed in the inner cavity of the battery chamber 2, enhances the protection of the battery pack, and improves the safety of the energy storage cabinet body 1 during operation. Furthermore, after the circulation pump body 31 is put into operation, water flow inside the serpentine tube 37 can be drawn and injected into the inner cavity of the distribution plate 32 through the water injection pipe 33. After being diverted through multiple first hoses 34, it is injected into the inner cavity of the hollow pressure plate 26, which can exchange heat during the operation of the battery pack and reduce the temperature of the battery pack during operation. The water flow after heat exchange can be collected through the second hose 35 into the inner cavity of the distribution plate 36 and re-enter the inner cavity of the serpentine tube 37 for cooling. The cooling water flow is circulated into the inner cavity of the hollow pressure plate 26, thereby reducing the operating temperature of the battery pack and extending the service life of the battery pack.
