Furthermore, the use of terms such as "first" and "second" is for distinguishing different components and does not indicate sequence or importance. "Front-back direction," "left-right direction," and "up-down direction" are respectively attached... Figure 1 and attached Figure 2 The "X", "Y", and "Z" directions are indicated in the following description. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the present disclosure.

[0029] According to a specific embodiment of this disclosure, refer to Figures 1 to 5 As shown, a vibration damping support device for a flow battery stack is provided. The vibration damping support device includes: a base 1, a support frame 2, a first vibration damping structure 4 disposed between the base 1 and the support frame 2, the first vibration damping structure 4 being arranged in the vertical direction, the first vibration damping structure 4 being used to provide vibration damping for the flow battery stack 10 in the vertical direction, the support frame 2 including a first frame body 21 and a first support plate 22 connected to the bottom of the first frame body 21; and a second support plate 3, the second support plate 3 being used to support and fix the flow battery stack 10 and to support it on the first support plate 22, wherein a second vibration damping structure 5 and a third vibration damping structure 6 are disposed between the second support plate 3 and the first frame body 21, the second vibration damping structure 5 being used to provide vibration damping for the flow battery stack 10 in the horizontal direction, and the third vibration damping structure 6 being used to provide vibration damping for the flow battery stack 10 in the front-back direction.

[0030] By the above technical solution, when the damping support device is used to support the flow battery stack 10, the flow battery stack 10 is supported on the second support plate 3. When the damping support device is subjected to external impact, since the first damping structure 4 is arranged between the first support plate 22 and the base 1, the first damping structure 4 can realize damping of the first support plate 22 in the up-down direction, so as to reduce the vibration energy transmitted to the flow battery stack 10 by the first support plate 22 and the second support plate 3, thereby realizing damping processing of the flow battery stack 10 in the up-down direction. Since the second damping structure 5 and the third damping structure 6 are arranged in the first frame body 21, and the second support plate 3 is arranged in the first frame body 21, the second damping structure 5 can realize damping of the second support plate 3 in the left-right direction when the second support plate 3 shakes in the left-right direction, and the third damping structure 6 can realize damping of the second support plate 3 in the front-rear direction when the second support plate 3 shakes in the front-rear direction. Therefore, the second damping structure 5 and the third damping structure 6 can realize damping processing of the second support plate 3 in the front-rear direction and the left-right direction, so as to reduce the vibration energy transmitted to the flow battery stack 10 by the second support plate 3, thereby realizing damping of the flow battery stack 10 in the left-right direction and the front-rear direction. Therefore, damping of the flow battery stack 10 in three directions is realized, the damping effect of the damping support device on the flow battery stack 10 is improved, so as to reduce displacement or deformation of the flow battery stack 10 caused by external vibration, thereby avoiding risks such as collapse of the stack, performance degradation of the stack, and even short circuit and leakage.

[0031] The damping support device of the present disclosure has simple structure, is easy to assemble, and is easy to realize connection and fixation between the flow battery stack 10 and the rack. By using the damping support device of the present disclosure to support the flow battery stack 10, large-scale application of the flow battery stack 10 in special application scenarios such as railways, ports and coal mines can be effectively improved, thereby expanding the application scenarios of the flow battery stack 10. The damping support device can reduce the failure of the flow battery stack 10 caused by external impact, especially reduce the risk that the battery system is easily damaged by strong ground vibration in earthquake-prone areas, thereby reducing safety hazards and protecting personnel and equipment safety.

[0032] According to the embodiments provided by the present disclosure, reference can be made to the description of the damping support device in the first aspect of the present disclosure. Figures 1 to 3As shown, the second damping structure 5 includes second damping members 51 abutting the left and right sides of the second support plate 3, wherein the second damping members 51 extend in the front-rear direction, and / or the third damping structure 6 includes third damping members 61 abutting the front and rear sides of the second support plate 3, wherein the third damping members 61 extend in the left-right direction. In this way, the second damping members 51 can dampen the second support plate 3 and the two side walls of the first frame 21 arranged opposite in the left-right direction when the second support plate 3 shakes in the left-right direction. The third damping members 61 can dampen the second support plate 3 and the two side walls of the first frame 21 arranged opposite in the front-rear direction when the second support plate 3 shakes in the front-rear direction. Moreover, the second damping structure 5 and the third damping structure 6 can simultaneously dampen the flow battery stack 10 in the left-right direction and the front-rear direction by damping the second support plate 3, so as to reduce the vibration impact of the second support plate 3 and the first frame 21 to the flow battery stack 10 when the damping support device is subjected to external impact, thereby improving the damping effect.

[0033] According to the embodiments provided by the present disclosure, referring to Figure 3 As shown, the second damping members 51 and the third damping members 61 are both made of elastic rubber. In this way, when the damping support device is subjected to external impact and the second support plate 3 moves relative to the first frame 21, it can be in contact with the second damping members 51 or the third damping members 61, so as to absorb and dissipate the impact energy between the second support plate 3 and the first frame 21 by the elastic deformation of the elastic rubber when subjected to impact, so as to reduce the resonance effect and improve the stability and safety of the flow battery stack 10. In other embodiments, the second damping members 51 can also be constructed of other elastic materials such as sponge as needed, and the present disclosure does not make specific limitations in this regard.

[0034] According to the embodiments provided by the present disclosure, referring to Figure 2 As shown, the bottom of the second support plate 3 is provided with a plurality of rolling members 31 abutting the first support plate 22. The flexibility of the rolling members 31 helps to facilitate smooth movement of the second support plate 3 in the front-rear direction or the left-right direction, and through the cooperation of the rolling members 31 with the second damping members 51 and the third damping members 61, it can be ensured that the second support plate 3 does not lose balance during movement of the flow battery stack 10, so as to reduce the risk of internal components being misaligned due to loss of balance when the flow battery stack 10 is subjected to impact, thereby improving the stability and safety of the flow battery stack 10. The rolling members 31 can be constructed as universal wheels or balls to enable movement in multiple directions, and the present disclosure does not make specific limitations in this regard. In some embodiments, the universal wheels themselves can also be designed with damping structures such as built-in springs or rubber pads to further absorb vibrations during movement of the second support plate 3 relative to the first support plate 22, and the present disclosure does not make specific limitations in this regard.

[0035] According to the embodiments provided by the present disclosure, referring to Figure 4 As shown in the figure, the first frame body 21 is provided with a connecting plate 211, the base 1 comprises a guide rod 11 extending in the up-down direction, the connecting plate 211 is in sliding connection with the guide rod 11, the first damping structure 4 comprises a first damping member 41 arranged between the connecting plate 211 and the base 1, and the first damping member 41 is configured as a damping spring. In this way, when the damping support device is subjected to external impact, the vibration of the first frame body 21 will drive the connecting plate 211 to slide downward along the guide rod 11, so that the damping spring between the connecting plate 211 and the base 1 can absorb and dissipate the vibration from the connecting plate 211, thereby achieving the damping of the first frame body 21 and the liquid flow battery stack 10 supported on the first frame body 21 in the first direction. Wherein, the damping spring can be sleeved on the guide rod 11, and the two ends of the damping spring are respectively abutted to the base 1 and the connecting plate 211, so as to slide the damping spring up and down along the guide rod 11, avoiding the condition that the damping spring is out of the base 1 and affects the damping effect.

[0036] Wherein, a support member can also be arranged between the connecting plate 211 and the base 1, the support member is in sliding connection with the guide rod 11, one end of the damping spring is abutted to the support member, and the other end is abutted to the base 1, the two sides of the support member are provided with second guide members, the second guide members are connected to the base 1 in the up-down direction, and the two sides of the support member are in sliding connection with the second support members. In this way, the connecting plate 211 can drive the support member to move downward to compress the damping spring, so as to ensure the balance and stability of the connecting plate 211 in the process of sliding up and down.

[0037] According to the embodiments provided by the present disclosure, referring to Figure 4As shown, the first damping structure 4 is configured to allow the first support plate 22 to move 0-10 mm in the up-down direction, and / or the second damping structure 5 is configured to allow the second support plate 3 to move 0-20 mm in the left-right direction, and / or the third damping structure 6 is configured to allow the second support plate 3 to move 0-20 mm in the front-back direction. In this way, when the damping support device is subjected to external impact, the flow battery stack 10 can move 0-10 mm in the up-down direction, the first damping structure 4 can achieve damping treatment of the flow battery stack 10 in the up-down direction; the flow battery stack 10 can move 0-20 mm in the left-right direction, the second damping structure 5 can achieve damping treatment of the flow battery stack in the left-right direction; the flow battery stack 10 can move 0-20 mm in the front-back direction, the third damping structure 6 can achieve damping treatment of the flow battery stack 10 in the front-back direction. In other embodiments, according to the specific arrangement of the first damping structure 4, the second damping structure 5 and the third damping structure 6, and the specifications of the flow battery stack 10, the first damping structure 4, the second damping structure 5 and the third damping structure 6 can also respectively achieve damping treatment when the movement distance of the battery stack in the up-down direction is greater than 10 mm, and the movement distance in the left-right direction and the front-back direction is greater than 20 mm, which is not specifically limited in the present disclosure.

[0038] According to a second aspect of the present disclosure, a misalignment prevention structure is provided for fixing a plurality of single cells arranged in sequence in a flow battery stack, the misalignment prevention structure being supported on the second support plate 3 of the damping support device, the misalignment prevention structure comprising a fixing frame 7 supported and fixed on the second support plate 3, the fixing frame 7 comprising a first sub-frame 71 and a second sub-frame 72 detachably connected, the first sub-frame 71 and the second sub-frame 72 enclosing a containing space for containing the flow battery stack 10. Since the flow battery stack 10 is composed of a plurality of precise components, including electrodes, separators, current collectors, etc., the close fit and accurate alignment between these battery components are crucial to the performance of the flow battery stack. In this way, the first sub-frame 71 and the second sub-frame 72 can clamp the flow battery stack 10 in the containing space to provide stable support to both sides of the flow battery stack 10, achieving close fixation of the flow battery stack 10, effectively preventing displacement or loosening of the flow battery stack 10 composed of battery monomers under vibration or impact, and preventing misalignment of key components in the flow battery stack 10 causing leakage, thereby preventing the flow battery stack 10 from collapsing under impact, thereby improving the safety of the entire flow battery stack 10. In addition, since the first sub-frame 71 and the second sub-frame 72 are detachably connected, it is convenient for workers to fix the flow battery stack 10 under various working conditions and to maintain the flow battery stack 10.

[0039] According to the embodiments provided in this disclosure, refer to Figure 5 As shown, both the first subframe 71 and the second subframe 72 include a main body plate 73 and multiple connecting arms 74 arranged circumferentially around the main body plate 73. The fixing frame 7 includes connecting rods 75, which extend along the interval direction between the first subframe 71 and the second subframe 72. Adjacent connecting arms 74 of the first subframe 71 and the second subframe 72 are detachably connected by the connecting rods 75. In this way, the connecting rods 75 connect the connecting arms 74 of the first subframe 71 and the second subframe 72 together to form an integral frame, which can effectively prevent the first subframe 71 and the second subframe 72 from shifting relative to the flow battery stack 10 when subjected to vibration or impact, ensuring that the flow battery stack 10 always remains in a predetermined position and angle. Furthermore, the connecting rods 75 can ensure that the first subframe 71 and the second subframe 72 on both sides of the flow battery stack 10 are evenly stressed, avoiding structural deformation or damage caused by excessive local stress, and helping to improve the overall safety of the flow battery stack 10.

[0040] According to embodiments of this disclosure, reference is made to Figure 5 As shown, both the first sub-frame 71 and the second sub-frame 72 are constructed in a "well" shape. This "well" shape supports the flow battery stack 10 on both sides. Firstly, it allows for the design of reinforcing ribs on the main body plate 73, increasing its structural stability and enabling external pipes to connect to the flow battery stack 10 through gaps. Secondly, the "well" shape has connecting arms 74 formed circumferentially, which are integrally formed with the main body plate 73, ensuring the structural reliability of the first and second sub-frames 71 and 72. This ensures the weight of the flow battery stack 10 is evenly distributed on the main body plate 73, preventing deformation or damage caused by excessive local pressure, thus extending the service life of the flow battery stack 10. Furthermore, the outer shell of the connecting arms 74 is made of insulating material, protecting the equipment and personnel while also providing circumferential support for the flow battery stack 10.

[0041] According to the embodiments provided in this disclosure, refer to Figure 5 As shown, a through hole is formed on the connecting arm 74, and the connecting rod 75 has a threaded portion 741 extending out of the through hole, with a nut 742 threadedly connected to the threaded portion 741. In this way, the connection strength between the first sub-frame 71 and the second sub-frame 72 and the connecting arm 74 is ensured through the connection of the threaded rod and the nut 742, thereby improving the safety and reliability of the fixing frame 7. Furthermore, it allows for a detachable connection between the first sub-frame 71, the second sub-frame 72, and the connecting arm 74, facilitating maintenance of the flow battery stack 10.

[0042] According to the embodiments provided in this disclosure, refer to Figure 3As shown, the second support plate 3 is provided with a second frame body 32, the second frame body 32 is formed with a positioning groove 321, and the fixing frame 7 is arranged in the positioning groove 321. In this way, through the positioning of the fixing frame 7 by the positioning groove 321, the positioning of the flow battery stack 10 can be realized, so that the position of the flow battery stack 10 can be relatively fixed with the second support plate 3, so as to ensure the damping effect on the flow battery stack 10 and improve the safety of the flow battery stack 10.

[0043] According to the embodiments provided by the present disclosure, the fixing frame 7 is made of insulating material. In this way, the electrical safety of the flow battery stack 10 can be ensured, because there is high voltage between the battery monomers in the flow battery stack 10, by making the fixing frame 7 for fixing the flow battery stack 10 made of insulating material, so as to effectively prevent the short circuit of current between different battery monomers or between the fixing frame 7. At the same time, the personnel and the flow battery stack 10 can be protected, to prevent the electric shock accident of the operator when contacting the fixing frame 7, and to ensure the safety of the personnel and the equipment.

[0044] In the following, reference will be made to Figures 1 to 5As shown, the present disclosure will be combined with the above specific embodiments to introduce the specific use process of the damping support device for the flow battery stack 10 in detail. When the damping support device of the present disclosure is used to support the flow battery stack 10, the flow battery stack 10 is placed in the accommodation space between the first sub-frame 71 and the second sub-frame 72, the connecting arms 74 of the first sub-frame 71 and the second sub-frame 72 are connected in the circumferential direction by the connecting rod 75, the fixing of the first sub-frame 71 and the second sub-frame 72, the flow battery stack 10 installed on the fixed frame 7 is placed in the second frame body 32 of the second support plate 3, and the fixed frame 7 is fixed in the positioning groove 321 to realize the positioning of the position of the flow battery stack 10 and the fixed frame 7. When the damping support device is subjected to external impact, the first support plate 22 vibrates to drive the connecting plate 211 to move downward along the guide rod 11, at this time the damping spring is compressed under the action of pressure to be compressed to be able to absorb the vibration energy from the first support plate 22, and the elastic deformation blocks the first support plate 22 from continuing to move downward, so as to realize the damping of the flow battery stack 10 in the up-down direction by damping the first support plate 22 in the up-down direction. At the same time, the second support plate 3 shakes relative to the first frame body 21 to drive the flow battery stack 10 to move, since the second support plate 3 is connected with the universal wheel, when the second support plate 3 moves in the left-right direction or the front-rear direction, the universal wheel can cooperate with the second support plate 3 to move stably, reducing the risk of dislocation of the flow battery stack 10 caused by the loss of balance of the second support plate 3 during movement. The second support plate 3 can contact the second damping member 51 when moving in the left-right direction, so that the second damping member 51 made of elastic rubber can be elastically deformed to absorb and dissipate the impact energy between the two sides of the second support plate 3 and the first frame body 21 arranged in the left-right direction, so as to realize the damping of the flow battery stack 10 in the left-right direction by damping the second support plate 3. The second support plate 3 can contact the third damping member 61 when moving in the front-rear direction, so that the third damping member 61 made of elastic rubber can be elastically deformed to absorb the impact energy between the two sides of the second support plate 3 and the first frame body 21 arranged in the front-rear direction. Therefore, when the damping support device of the present application is used to support the flow battery stack 10, the damping of the flow battery stack 10 in the up-down direction, the left-right direction and the front-rear direction can be realized at the same time.

[0045] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments.
