Description

Technical Field

[0001] This utility model relates to the field of energy storage power technology, and more specifically, to a containerized energy storage impulse power supply. Background Technology

[0002] With the transformation of the global energy structure and the implementation of the "dual-carbon" strategy, the proportion of renewable energy generation, such as photovoltaic and wind power, is gradually increasing. However, the power generation characteristics of these renewable energy sources are volatile and intermittent, especially under extreme weather conditions such as windless, sunless, cold, and freezing weather, posing challenges to the stability of power supply. To address this challenge, energy storage technology has become an important means to ensure grid stability and improve energy efficiency. Containerized energy storage systems (CBESS), as an innovative energy storage solution, have seen rapid development in recent years. This system installs battery energy storage units inside standardized containers. This design not only simplifies infrastructure construction costs but also shortens the construction cycle, improves modularity, and enhances the convenience of transportation and installation.

[0003] A search revealed that Chinese patent CN220963565U discloses an integrated energy storage power supply. By setting a buffer component inside the housing cavity and surrounding the outside of the battery cell module, the buffer component can effectively reduce the impact force on the battery cell module when the integrated energy storage power supply is subjected to external impact, effectively improving the anti-collision performance of the energy storage power supply, enabling the energy storage power supply to work safely and stably, and has extremely high practicality.

[0004] In summary, while the energy storage power supply structure design has the effect of buffering impact forces, in actual use, the power supply itself continuously generates heat during operation, which requires heat dissipation. However, the design of the heat dissipation holes can easily allow moisture to enter the power supply box, causing the power supply to become damp and affecting its service life. Therefore, a structure to prevent moisture from entering needs to be designed on the heat dissipation holes. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a containerized energy storage impact power supply, comprising a housing, a support plate disposed at the bottom of the inner cavity of the housing, and a plurality of support blocks arranged in a matrix below the support plate at the bottom of the inner cavity of the housing. A shock-absorbing pad is disposed at the contact position between the top of each support block and the bottom of the support plate. A plurality of energy storage cells are mounted on the top of the support plate. A lifting locking frame is connected to the inside of the housing above the energy storage cells, and the inside of the housing is fixedly connected above the lifting locking frame. A fixed plate is attached, and several first springs are connected between the bottom of the fixed plate and the top of the lifting locking frame. A screw is connected to the middle of the fixed plate. A connecting cover is connected to the top of the housing near the screw. Fans are installed on both sides of the connecting cover on the top inner wall of the housing. Air inlets are provided on both sides of the top two sides of the housing. Power cable entry and exit covers for power cable harnesses are provided on both sides of the housing. Several heat dissipation holes are evenly distributed on the bottom of the housing, and a protective mechanism is provided at the bottom of each heat dissipation hole.

[0007] As a further improvement to the technical solution of this utility model, a connecting seat is provided at the bottom of the housing near the four corners, and each connecting seat is fixedly connected to the mounting surface by bolts.

[0008] As a further improvement to the technical solution of this utility model, the support plate is provided with air holes evenly distributed inside, the bottom of the support block is welded and fixed to the bottom inner wall of the box shell, and the shock-absorbing pad is bonded and fixed to the top of the support block with glue.

[0009] As a further improvement to the technical solution of this utility model, T-shaped locking blocks are provided at both ends of the lifting locking frame near the two inner walls of the housing. T-shaped sliding grooves are provided on the outer sides of the two inner walls of the housing in the vertical direction corresponding to the two T-shaped locking blocks. A pressure frame is connected to the inner wall of the lifting locking frame. A bearing seat is provided at the top of the pressure frame corresponding to the end of the screw, and a protective pad is provided at the bottom of the pressure frame.

[0010] As a further improvement to the technical solution of this utility model, the fixing plate is provided with a screw hole matching the external thread structure of the screw, the screw and the fixing plate are connected by a thread, and the fixing plate is provided with a grid hole evenly.

[0011] As a further improvement to the technical solution of this utility model, the top of the fan is fixedly connected to the top inner wall of the housing by screws, the top of the housing is provided with a through hole corresponding to the connection of the connecting cover, the connecting cover is connected to the top of the housing by threads, and the vertical cross-section of the air inlet is stepped.

[0012] As a further improvement to the technical solution of this utility model, the protective mechanism includes a fixing block fixedly connected to the inner wall of the heat dissipation hole, a telescopic rod fixedly connected to the bottom end of the fixing block, a sealing plate fixedly connected to the bottom end of the telescopic rod extending to the outside of the housing, a second spring connected to the bottom of the fixing block and the top of the sealing plate, the second spring being sleeved on the outside of the telescopic rod, and a sealing gasket provided at the top edge of the sealing plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. The housing of this utility model is equipped with a structure for locking and protecting the position of the energy storage cell. In use, by opening the connecting cover, rotating the screw drives the lifting locking frame to move up and down in the vertical direction. When the screw descends, it can drive the lifting locking frame to descend. When the screw rises, under the contraction of the first spring, the lifting locking frame rises, unlocking the pressing state on the energy storage cell, thereby realizing the replacement and locking of the internal energy storage cell. By setting a protective pad at the bottom of the lifting locking frame and setting a shock-absorbing pad between the support plate and the support block, when the housing vibrates, it can effectively buffer and protect against vibration and reduce the pressure damage to the top of the energy storage cell.

[0015] 2. By setting up a protective mechanism, in conjunction with a fan and stepped air intake, the heat inside the housing increases during use. The fan generates air pressure, which acts on the energy storage cells through the fixed plate and lifting locking frame for air cooling. During this process, the hot air pressure inside the housing gradually increases. When it exceeds a critical value, it pushes the second spring to compress, and the telescopic rod extends accordingly. The sealing plate is blown downward by the hot air force, and the hot air is discharged to the outside of the housing, thereby achieving the heat dissipation effect. When the hot air pressure is low and insufficient to push the second spring to extend, the sealing plate and sealing gasket keep the heat dissipation holes closed to prevent the bottom from getting damp.

Air inlets 13 are provided on both sides of the top two sides of the housing 1. Power cable entry and exit covers 14 are provided on both sides of the housing 1 for the power cable harness to pass through. Several heat dissipation holes 15 are evenly provided on the bottom of the housing 1. A protective mechanism is provided at the bottom of each heat dissipation hole 15.

[0023] As attached Figure 1 As shown, a connecting seat 2 is provided at the bottom of the housing 1 near the four corners. Each connecting seat 2 is fixed to the mounting surface by bolts, which facilitates the installation and fixation of the housing 1, and thus facilitates the stable installation of the internal energy storage cell 6.

[0024] As attached Figure 1As shown, the support plate 3 has evenly distributed ventilation holes inside. The bottom of the support block 4 is welded and fixed to the bottom inner wall of the housing 1. The shock-absorbing pad 5 is glued and fixed to the top of the support block 4, so that heat can pass through the support plate 3 into the heat dissipation hole 15 and facilitate the connection between the support block 4 and the shock-absorbing pad 5.

[0025] As attached Figure 1 and attached Figure 3 As shown, T-shaped locking blocks 701 are provided at both ends of the lifting locking frame 7 near the two inner walls of the housing 1. T-shaped sliding grooves 702 are provided on the outer sides of the two inner walls of the housing 1 in the vertical direction corresponding to the two T-shaped locking blocks 701. A pressure frame 703 is connected to the inner wall of the lifting locking frame 7. A bearing seat 705 is provided at the top of the pressure frame 703 corresponding to the end of the screw 10. A protective pad 704 is provided at the bottom of the pressure frame 703 to facilitate the vertical movement of the lifting locking frame 7, thereby realizing the pressing and releasing of the energy storage cell 6. The protective pad 704 can reduce the pressure damage to the top of the energy storage cell 6.

[0026] As attached Figure 1-2 As shown, the fixed plate 8 has a screw hole 801 inside that matches the external thread structure of the screw 10. The screw 10 and the fixed plate 8 are connected by a thread. The fixed plate 8 has a grid hole 802 evenly arranged inside, which makes it easy for the screw 10 to rotate stably on the fixed plate 8. The grid hole 802 can also make the air blown by the fan 12 above effectively blow onto the energy storage cell 6.

[0027] As attached Figure 1 As shown, the top of the fan 12 is fixedly connected to the top inner wall of the housing 1 by screws. The top of the housing 1 is provided with a through hole 111 at the connection point of the connecting cover 11. The connecting cover 11 is connected to the top of the housing 1 by threads. The vertical section of the air inlet 13 is stepped, which facilitates the installation and fixing of the fan 12. The detachable connecting cover 11 allows the user to open it and rotate the screw 10 to perform the pressing and releasing operation of the energy storage cell 6.

[0028] As attached Figure 1 and attached Figure 4 As shown, the protective mechanism includes a fixing block 16 fixedly connected to the inner wall of the heat dissipation hole 15. A telescopic rod 17 is fixedly connected to the bottom end of the fixing block 16. The bottom end of the telescopic rod 17 extends to the outside of the housing 1 and is fixedly connected to a sealing plate 18. A second spring 19 is connected to the bottom of the fixing block 16 and the top of the sealing plate 18. The second spring 19 is sleeved on the outside of the telescopic rod 17. A sealing gasket 20 is provided at the top edge of the sealing plate 18. The protective mechanism facilitates the discharge of hot air when the heat inside the housing 1 is high and the air pressure generated by the fan 12 is increased during use, thereby effectively dissipating heat. It also keeps the housing in a closed state when the internal air pressure is low to prevent the bottom from getting damp.

[0029] Working principle: This utility model designs a containerized energy storage impulse power supply, the specific structure of which is shown in the attached instruction manual. Figure 1-4 As shown, this technical solution designs a container-type outer casing 1 for the energy storage impact power supply. It is fixed to the mounting surface via a connecting seat 2. The interior is equipped with a structure for locking and protecting the position of the energy storage cell 6. In use, by opening the connecting cover 11, rotating the screw 10 drives the lifting locking frame 7 to move up and down in the vertical direction. When the screw 10 descends, it can drive the lifting locking frame 7 to descend. When the screw 11 rises, under the contraction of the first spring 9, the lifting locking frame 7 rises, unlocking the pressing state of the energy storage cell 6. This enables the replacement and locking of the internal energy storage cell 6. By setting a protective pad 704 at the bottom of the lifting locking frame 7 and a shock-absorbing pad 5 between the support plate 4 and the support block 4, the shell 1 can effectively buffer and protect against vibration and reduce the pressure damage to the top of the energy storage cell 6.

[0030] By setting up a protective mechanism, in conjunction with the fan 12 and the stepped air inlet 13, when the heat inside the housing 1 increases during use, the fan 12 generates air pressure, which acts on the energy storage cell 6 through the fixing plate 8 and the lifting locking frame 7 for air cooling. During the process, the hot air pressure inside the housing 1 gradually increases. When it exceeds a critical value, it pushes the second spring 19 to compress, and the telescopic rod 17 extends accordingly. The sealing plate 18 is blown downward by the hot air force, and the hot air is discharged to the outside of the housing 1, thereby achieving the effect of heat dissipation. When the hot air pressure is low and insufficient to push the second spring 19 to extend, the sealing plate 18 and the sealing gasket 20 keep the heat dissipation hole 15 closed to prevent the bottom from getting damp.

[0031] In the accompanying drawings of the embodiments disclosed in this utility model, only the structures involved in the embodiments of this utility model are shown. Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
