Description

Technical Field

[0001] This utility model relates to the field of battery pack technology for energy storage power stations, specifically a mounting bracket for battery packs in energy storage power stations. Background Technology

[0002] Battery packs are the core functional components of energy storage power stations, enabling energy storage, dispatching, and supply-demand balance. They are composed of dozens or even hundreds of individual cells connected in series and parallel, and have the ability to store and release large-capacity, high-rate energy. Due to the large overall size and concentrated weight of the battery pack, and the need to maintain an absolutely stable installation state during operation to prevent the cell connection terminals from loosening.

[0003] The existing mounting brackets for battery packs in energy storage power stations adopt a traditional rigid frame design. The basic structure includes a flat bearing base, side limiting plates, and mechanical fasteners. In actual installation, the bearing base must first be fixed to the concrete mounting platform or metal bracket of the energy storage power station with expansion bolts. Then, the operators work together to lift the battery pack to the designated area of ​​the base, adjust the position of the battery pack to align it with the side limiting plates, and finally use wrenches and other tools to tighten the fastening bolts one by one to fix the battery pack.

[0004] Existing mounting brackets for energy storage power station battery packs can effectively protect the battery packs, but there are still some shortcomings in their use. Current technology relies on tools for installation, requiring various specialized tools to tighten and loosen bolts. The installation process requires the cooperation of multiple personnel, which prolongs the installation and replacement time of the battery packs. Furthermore, existing mounting brackets are not designed with a dedicated shock absorption structure, relying only on rubber pads between the base and the platform for simple cushioning. This cannot absorb the impact force generated by equipment transportation, equipment resonance, etc., and the electrode structure of the battery cells inside the battery pack is easily damaged by long-term exposure to vibration.

[0005] Therefore, this utility model proposes a mounting bracket for battery packs in energy storage power stations to address the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a mounting bracket for battery packs in energy storage power stations, and to solve the following technical problems: 1. Solve the problem that existing technologies rely on tools for installation, requiring the use of various specialized tools to tighten and loosen bolts; 2. This addresses the problem that existing technologies lack a dedicated shock-absorbing structure, making it unable to absorb the impact forces generated during equipment transportation and equipment resonance, which can damage the electrode structure of the battery cells inside the battery pack.

[0007] The purpose of this utility model can be achieved through the following technical solution: a mounting bracket for a battery pack in an energy storage power station, including a mounting base, a protective frame fixedly connected to the top of the mounting base, a battery pack body mounted on the top of the mounting base, an installation component inside the mounting base, and a buffer component at the bottom of the mounting base; The mounting assembly includes a mounting rod and a fixing rod. The mounting rod is slidably connected inside the mounting base. Two support frames are fixedly connected to the outer periphery of the mounting rod. A connecting rod is rotatably connected inside each of the two support frames. A sliding frame is rotatably connected to the other end of each of the two connecting rods. A locking block is fixedly connected to the front end of each of the two sliding frames. The fixing rod is fixedly connected inside the mounting base. The mounting rod is slidably connected to the outer periphery of the fixing rod. A spring is sleeved on the outer periphery of the fixing rod. A mounting block is fixedly connected to the bottom of the battery pack body. A locking groove is opened at both ends of the mounting block. An mounting groove is opened inside the mounting base. The mounting block is installed inside the mounting groove. The two locking blocks are respectively locked into the two locking grooves.

[0008] As a preferred embodiment of this utility model: the buffer assembly includes multiple damping rods, each of the multiple damping rods is fixedly connected to the bottom of the mounting base, the bottom of each of the multiple damping rods is fixedly connected to a base, and each of the multiple damping rods is fitted with a spring.

[0009] As a preferred embodiment of this utility model: the buffer assembly further includes two fixing frames one and two fixing frames two. The two fixing frames one are fixedly connected to the bottom of the mounting base. The bottom of the two fixing frames one is rotatably connected to a connecting rod. The bottom of the two connecting rods is rotatably connected to a moving block. The two fixing frames two are fixedly connected to the top of the base. The two fixing frames two are fixedly connected to a support rod on opposite sides. The two moving blocks are slidably connected to the outer periphery of the support rod. A spring three is sleeved on the outer periphery of the support rod.

[0010] As a preferred embodiment of this utility model: two slide rods are fixedly connected inside the mounting base, and the two locking blocks are slidably connected to the outer periphery of the two slide rods respectively.

[0011] As a preferred embodiment of this utility model: two support blocks are fixedly connected to the bottom of the battery pack body, and two support grooves are opened on the top of the mounting base, with the two support blocks respectively installed inside the two support grooves.

[0012] As a preferred embodiment of this utility model: one end of the spring is fixedly connected to the front end of the mounting rod, and the other end of the spring is fixedly connected to the inside of the mounting base.

[0013] As a preferred embodiment of this utility model: the tops of the plurality of springs are fixedly connected to the bottom of the mounting base, and the bottoms of the plurality of springs are fixedly connected to the top of the base.

[0014] As a preferred embodiment of this utility model: the three ends of the spring are respectively fixedly connected to the two moving blocks on opposite sides.

[0015] The beneficial effects of this utility model are: (1) This utility model pushes the spring on the outer periphery of the mounting rod to compress the mounting rod, thereby driving the two support frames on the mounting rod to move synchronously. This causes the connecting rod inside the support frame to push the sliding frame and the locking block to slide, embedding the mounting block at the bottom of the battery pack body into the mounting groove of the mounting seat. At the same time, the support block is locked into the support groove to achieve initial positioning. After the mounting rod is released, the spring returns to its elastic state, pushing the locking block to accurately engage with the locking grooves on both sides of the mounting block. The entire installation process does not require the use of complex tools, and the operation is simple and quick, which can greatly shorten the installation time of the battery pack and reduce labor costs.

[0016] (2) This utility model forms a primary buffer by multiple damping rods at the bottom of the mounting base and springs two sleeved on the outer periphery. Springs two can directly absorb the vibration energy in the vertical direction, while the damping rods can suppress the resonance phenomenon caused by the spring rebound. When the mounting base is vibrated and moves downward, the bottom fixing frame one drives the connecting rod to push the moving block to slide along the support rod, causing the spring three on the outer periphery of the support rod to deform. The elastic force of spring three further absorbs the vibration energy, forming a secondary buffer. The double buffer design can significantly reduce the damage of vibration to the internal cells of the battery pack, effectively extend the service life of the battery pack, and adapt to the complex operating environment of the energy storage power station.

[0024] Please see Figure 5As shown, the buffer assembly includes multiple damping rods 17, all of which are fixedly connected to the bottom of the mounting base 1. The bottom of each of the multiple damping rods 17 is fixedly connected to a base 18. Each of the multiple damping rods 17 is fitted with a second spring 19. The buffer assembly also includes two first fixing brackets 20 and two second fixing brackets 23. Each of the two first fixing brackets 20 is fixedly connected to the bottom of the mounting base 1.

[0025] Specifically, the damping rod 17 is fixedly connected between the bottom of the mounting base 1 and the base 18, which can play the role of shock absorption and resonance suppression. Multiple damping rods 17 are directly connected to the mounting base 1 and the base 18, allowing the total load to be distributed through multiple support points. The damping rods 17 are rubber composite type, with a rated load capacity of 500-1000 kg. A combination of four damping rods 17 can withstand a gravity pressure of 2-4 tons. The maintenance cycle is three years, and the service life is twenty years, meeting the requirements for battery racks in energy storage power stations. The top of the base 18 connects the damping rod 17 to the fixing frame 23. Spring 2 19 is sleeved on the outer periphery of the damping rod 17, with its top fixed to the bottom of the mounting base 1 and its bottom fixed to the top of the base 18, capable of absorbing... For vertical vibration energy, the first fixing bracket 20 is fixed to the bottom of the mounting base 1 and is used to rotatably connect the connecting rod 21. The two ends of the connecting rod 21 are respectively rotatably connected to the first fixing bracket 20 and the moving block 22, which can transmit the force during vibration. The moving block 22 is slidably connected to the outer periphery of the support rod 24, which is used to rotatably connect the connecting rod 21 and is also connected to the third spring 25, and can slide along the support rod 24. The second fixing bracket 23 is fixed to the top of the base 18 and is used to fix the support rod 24.

The third spring 25 is sleeved on the outer periphery of the support rod 24, and its two ends are respectively connected to the two moving blocks 22 facing each other, which can absorb vibration energy.

[0026] The working principle of this utility model is as follows: When the battery pack body 3 needs to be installed, the operator pushes the installation rod 7. Since the installation rod 7 is slidably connected inside the mounting base 1 and outside the fixed rod 13, its movement will compress the spring 14 on the outside of the fixed rod 13. At the same time, it will drive the two support frames 8 fixed on the outside to move synchronously. The movement of the support frames 8 will cause the connecting rod 9, which is rotatably connected inside, to rotate. The rotation of the connecting rod 9 will further push the sliding frame 10 and the front fixed locking block 11 to slide along the sliding rod 12 inside the mounting base 1. Then, the mounting block 4 at the bottom of the battery pack body 3 will be embedded into the mounting groove 6 of the mounting base 1. At the same time, the two support blocks 15 at the bottom of the battery pack body 3 will be correspondingly locked into the support groove 16 at the top of the mounting base 1, completing the initial positioning. At this time, the installation rod 7 is released. After the spring 14 loses the external force, it elastically returns to its original position, pushing the installation rod 7 to move in the opposite direction. Then, through the support frame 8 and the connecting rod 9, the sliding frame 10 and the locking block 11 will be reset, so that the two locking blocks 11 are accurately locked into the locking grooves 5 at the left and right ends of the mounting block 4, and finally the battery pack body 3 is firmly installed.

[0027] When the mounting bracket is transported, the mounting base 1 moves downward due to vibration, and the multiple damping rods 17 fixedly connected to the bottom extend and retract accordingly. The springs 19 wrapped around their outer periphery are compressed synchronously. The springs 19 directly absorb the vertical vibration energy through deformation, while the damping rods 17 can effectively suppress the resonance phenomenon generated during the rebound of the springs 19, forming a primary buffer. At the same time, the downward movement of the mounting base 1 will drive the two fixed brackets 20 at the bottom to move downward synchronously. The movement of the fixed brackets 20 causes the connecting rod 21 rotatably connected at the bottom to change its angle. The connecting rod 21 then pushes the moving block 22 rotatably connected at the bottom to slide along the support rod 24 between the two fixed brackets 23 at the top of the base 18. When the moving block 22 slides, it will squeeze or stretch the spring 25 on the outer periphery of the support rod 24. The spring 25 further absorbs the vibration energy through its own deformation, forming a secondary buffer. Through the synergistic effect of the primary and secondary buffers, the impact of vibration on the battery pack body 3 at the top of the mounting base 1 is greatly reduced, protecting the internal cells of the battery pack from damage.

[0028] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
