It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be construed as limiting the present disclosure.

[0023] According to the specific implementation of the present disclosure, Figures 1 to 5 As shown, a vibration reduction support device for a liquid flow battery stack is provided, the vibration reduction support device comprising: a base 1, a support frame 2, a first vibration reduction structure 4 is arranged between the base 1 and the support frame 2, the first vibration reduction structure 4 is arranged in the up-down direction, and the first vibration reduction structure 4 is used to provide vibration reduction for the liquid flow battery stack 10 in the up-down direction, the support frame 2 comprises 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 is used to carry and fix the liquid flow battery stack 10, and is supported on the first support plate 22, wherein a second vibration reduction structure 5 and a third vibration reduction structure 6 are arranged between the second support plate 3 and the first frame body 21, the second vibration reduction structure 5 is used to provide vibration reduction for the liquid flow battery stack 10 in the left-right direction, and the third vibration reduction structure 6 is used to provide vibration reduction for the liquid flow battery stack 10 in the front-back direction.

[0024] Through the above technical solution, when the vibration reduction support device is used to support the liquid flow battery stack 10, the liquid flow battery stack 10 is supported on the second support plate 3. When the vibration reduction support device is subjected to external impact, since there is a first vibration reduction structure 4 between the first support plate 22 and the base 1, the first vibration reduction structure 4 can achieve vibration reduction of the first support plate 22 in the up and down directions, so as to reduce the vibration energy transmitted to the liquid flow battery stack 10 through the first support plate 22 and the second support plate 3, thereby achieving vibration reduction treatment of the liquid flow battery stack 10 in the up and down directions. Since the second vibration reduction structure 5 and the third vibration reduction structure 6 are arranged in the first frame 21, and the second support plate 3 is placed in the first frame 21, the second vibration reduction structure 5 can achieve vibration reduction of the second support plate 3 in the left and right directions when the second support plate 3 shakes in the left and right directions, and the third vibration reduction structure 6 can achieve vibration reduction of the second support plate 3 in the front and back directions when the second support plate 3 shakes in the front and back directions. Therefore, the second vibration reduction structure 5 and the third vibration reduction structure 6 can reduce the vibration energy transmitted to the flow battery stack 10 through the second support plate 3 by vibration reduction treatment in the front and back directions and the left and right directions of the second support plate 3, thereby achieving vibration reduction of the flow battery stack 10 in the left and right directions and the front and back directions. Therefore, vibration reduction of the flow battery stack 10 in three directions at the same time is achieved, and the vibration reduction effect of the vibration reduction support device on the flow battery stack 10 is improved, so that the displacement or deformation of the flow battery stack 10 caused by external vibration can be reduced, resulting in the collapse of the stack, the degradation of the stack performance, and even the risk of short circuit, leakage, etc.

[0025] The vibration reduction support device disclosed in the present invention has a simple structure, is easy to assemble, and is easy to connect and fix the flow battery stack 10 to the stand. By using the vibration reduction support device disclosed in the present invention to support the flow battery stack 10, it can effectively improve the large-scale application of the flow battery stack 10 in special application scenarios such as railways, ports, and coal mines, thereby expanding the application scenarios of the flow battery stack 10.

[0026] According to the embodiments provided by the present disclosure, Figures 1 to 3As shown, the second vibration damping structure 5 includes a second vibration damping member 51, and the second vibration damping member 51 is abutted on both the left and right sides of the second support plate 3, wherein the second vibration damping member 51 extends in the front-to-back direction, and / or the third vibration damping structure 6 includes a third vibration damping member 61, and the third vibration damping member 61 is abutted on both the front and rear sides of the second support plate 3, wherein the third vibration damping member 61 extends in the left-to-right direction. In this way, the second vibration damping member 51 can perform vibration damping treatment between the second support plate 3 and the two side walls of the first frame body 21 that are arranged opposite to each other in the left-to-right direction when the second support plate 3 shakes in the left-to-right direction. The third vibration damping member 61 can perform vibration damping treatment between the second support plate 3 and the two side walls of the first frame body 21 that are arranged opposite to each other in the front-to-back direction when the second support plate 3 shakes in the front-to-back direction. Furthermore, the second vibration reduction structure 5 and the third vibration reduction structure 6 can simultaneously reduce the vibration of the liquid flow battery stack 10 in the left-right direction and the front-back direction by reducing the vibration of the second support plate 3, so as to reduce the vibration impact between the second support plate 3 and the first frame 21 transmitted to the liquid flow battery stack 10 when the vibration reduction support device is subjected to external impact, thereby improving the vibration reduction effect.

[0027] According to the embodiments provided by the present disclosure, Figure 3 As shown, the second vibration damper 51 and the third vibration damper 61 are both made of elastic rubber. In this way, when the vibration damping support device is subjected to external impact, the second support plate 3 moves relative to the first frame 21, and can contact the second vibration damper 51 or the third vibration damper 61, so that the elastic rubber can be elastically deformed when subjected to impact to absorb and dissipate the impact energy between the second support plate 3 and the first frame 21, so as to reduce the resonance effect and improve the stability and safety of the flow battery stack 10. In other embodiments, the second vibration damper 51 can also be constructed as other elastic materials such as sponge as needed, and the present disclosure does not make specific restrictions on this.

[0028] According to the embodiments provided by the present disclosure, Figure 2 As shown, a plurality of rolling members 31 are provided at the bottom of the second support plate 3, and the rolling members 31 abut against the first support plate 22. The flexibility of the rolling members 31 helps to coordinate with the second support plate 3 to move smoothly in the front-to-back direction or the left-to-right direction. By cooperating with the second vibration damping member 51 and the third vibration damping member 61, it can be ensured that the second support plate 3 drives the flow battery stack 10 and the equipment will not lose balance due to vibration during the movement process, so as to reduce the risk of internal components being misaligned due to loss of balance when the flow battery stack 10 is impacted, thereby improving the stability and safety of the flow battery stack 10. Among them, the rolling member 31 can be constructed as a universal wheel or a ball to achieve movement in multiple directions, and the present disclosure does not make specific restrictions on this. In some embodiments, the universal wheel itself can also be designed with a vibration reduction structure, such as a built-in spring or a rubber pad, to further absorb the vibration of the second support plate 3 during the movement relative to the first support plate 22, and the present disclosure does not make specific restrictions on this.

[0029] According to the embodiments provided by the present disclosure, Figure 4 As shown, a connecting plate 211 is provided on the first frame 21, the base 1 includes a guide rod 11 extending in the up-down direction, the connecting plate 211 is slidably connected to the guide rod 11, and the first vibration reduction structure 4 includes a first vibration reduction member 41 provided between the connecting plate 211 and the base 1, and the first vibration reduction member 41 is configured as a vibration reduction spring. In this way, when the vibration reduction support device is subjected to external impact, the vibration of the first frame 21 will drive the connecting plate 211 to slide downward along the guide rod 11, so that the vibration reduction spring between the connecting plate 211 and the base 1 can absorb and dissipate the vibration from the connecting plate 211, thereby achieving vibration reduction of the first frame 21 and the flow battery stack 10 supported on the first frame 21 in the first direction. Among them, the vibration reduction spring can be sleeved on the guide rod 11, and the two ends of the vibration reduction spring are respectively abutted against the base 1 and the connecting plate 211, so that the vibration reduction spring slides up and down along the guide rod 11, and the vibration reduction spring is prevented from coming out of the base 1, which affects the vibration reduction effect.

[0030] Among them, a support member can also be arranged between the connecting plate 211 and the base 1, and the support member is slidably arranged on the guide rod 11, and one end of the shock-absorbing spring abuts against the support member, and the other end abuts against the base 1, and second guide members are arranged on both sides of the support member, and the second guide members are connected to the base 1 along the up and down directions, and both sides of the support member are slidably arranged on the second support member, so that the connecting plate 211 can compress the shock-absorbing spring by driving the support member to move downward, so as to ensure the balance and stability of the connecting plate 211 during the up and down sliding process.

[0031] According to the embodiments provided by the present disclosure, Figure 4As shown, the first vibration reduction structure 4 is configured to make the first support plate 22 move 0mm~10mm in the vertical direction, and / or, the second vibration reduction structure 5 is configured to make the second support plate 3 move 0mm~20mm in the left-right direction, and / or, the third vibration reduction structure 6 is configured to make the second support plate 3 move 0mm~20mm in the front-back direction. In this way, when the vibration reduction support device is subjected to external impact, the liquid flow battery stack 10 can move 0mm~10mm in the vertical direction, and the first vibration reduction structure 4 can achieve vibration reduction treatment of the liquid flow battery stack 10 in the vertical direction; the liquid flow battery stack 10 can move 0mm~20mm in the left-right direction, and the second vibration reduction structure 5 can achieve vibration reduction treatment of the liquid flow battery stack in the left-right direction; the liquid flow battery stack 10 can move 0mm~20mm in the front-back direction, and the third vibration reduction structure 6 can achieve vibration reduction treatment of the liquid flow battery stack 10 in the front-back direction. In other embodiments, according to the specific arrangement of the first vibration damping structure 4, the second vibration damping structure 5 and the third vibration damping structure 6, and the specifications of the liquid flow battery stack 10, the first vibration damping structure 4, the second vibration damping structure 5 and the third vibration damping structure 6 can also respectively achieve vibration damping when the moving distance of the battery stack in the up and down direction is greater than 10 mm and the moving distance in the left and right direction and the front and back direction is greater than 20 mm, and the present disclosure does not make specific restrictions on this.

[0032] According to the second aspect of the present disclosure, an anti-dislocation structure is provided for fixing a plurality of cells arranged in sequence in a flow battery stack. The anti-dislocation structure is supported on the second support plate 3 of the above-mentioned vibration reduction support device. The anti-dislocation structure includes a fixing frame 7, which is supported and fixed on the second support plate 3. The fixing frame 7 includes a first sub-frame 71 and a second sub-frame 72 that are detachably connected. The first sub-frame 71 and the second sub-frame 72 enclose a receiving space, and the receiving space is used to receive the flow battery stack 10. Among them, since the flow battery stack 10 is composed of a plurality of precision components, including electrodes, diaphragms, current collectors, etc., the close fit and precise 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 liquid flow battery stack 10 in the accommodating space to provide stable support for both sides of the liquid flow battery stack 10, and achieve tight fixation of the liquid flow battery stack 10, effectively preventing the liquid flow battery stack 10 composed of battery cells from being displaced or loosened under vibration or impact, and preventing key components in the liquid flow battery stack 10 from being misplaced and leaking, thereby preventing the liquid flow battery stack 10 from collapsing due to impact, thereby improving the safety of the entire liquid flow battery stack 10. In addition, since the first sub-frame 71 and the second sub-frame 72 are detachably connected, the liquid flow battery stack 10 can be fixed under various working conditions, and it is convenient for staff to maintain the liquid flow battery stack 10.

[0033] According to the embodiments provided by the present disclosure, Figure 5 As shown, the first sub-frame 71 and the second sub-frame 72 both include a main plate 73 and a plurality of connecting arms 74 arranged around the circumference of the main plate 73, and the fixing frame 7 includes a connecting rod 75, which extends along the spacing direction of the first sub-frame 71 and the second sub-frame 72, and two adjacent connecting arms 74 of the first sub-frame 71 and the second sub-frame 72 are detachably connected through the connecting rod 75. In this way, the connecting rod 75 connects the connecting arms 74 of the first sub-frame 71 and the connecting arms 74 of the second sub-frame 72 together to form an integral frame, which can effectively prevent the first sub-frame 71 and the second sub-frame 72 from being displaced relative to the liquid flow battery stack 10 when subjected to vibration or impact, ensuring that the liquid flow battery stack 10 always remains at a predetermined position and angle, and the connecting rod 75 can ensure that the first sub-frame 71 and the second sub-frame 72 on both sides of the liquid flow battery stack 10 are evenly stressed, avoiding structural deformation or damage caused by excessive local stress, which helps to improve the overall safety of the liquid flow battery stack 10.

[0034] According to the embodiment of the present disclosure, reference Figure 5 As shown, the first sub-frame 71 and the second sub-frame 72 are both constructed as a "well"-shaped structure. In this way, the first sub-frame 71 and the second sub-frame 72 can be constructed in a "well" shape, supported on both sides of the liquid flow battery stack 10. On the one hand, a reinforcing rib structure is designed on the main plate 73 to increase the structural stability of the main plate 73, and the external pipeline can be connected to the liquid flow battery stack 10 through the gap. On the other hand, a connecting arm 74 is formed in the circumference of the "well"-shaped structure. The connecting arm 74 can be integrally formed with the main plate 73 to ensure the structural reliability of the first sub-frame 71 and the second sub-frame 72, so that the weight of the liquid flow battery stack 10 can be evenly distributed on the main plate 73, and deformation or damage caused by excessive local pressure can be avoided, thereby helping to extend the service life of the liquid flow battery stack 10. In addition, the outer shell of the connecting arm 74 is set to an insulating material to protect the safety of equipment and staff, and can also support the liquid flow battery stack 10 in the circumferential direction.

[0035] According to the embodiments provided by the present disclosure, Figure 5 As shown, a through hole is formed on the connecting arm 74, and the connecting rod 75 has a screw portion 741 extending out of the through hole, and the screw portion 741 is threadedly connected with a nut 742. In this way, through the connection of the screw and the nut 742, the connection strength between the first sub-frame 71 and the second sub-frame 72 and the connecting arm 74 can be ensured to improve the safety and reliability of the fixing frame 7, and the detachable connection between the first sub-frame 71 and the second sub-frame 72 and the connecting arm 74 can also be achieved, so as to maintain the liquid flow battery stack 10.

[0036] According to the embodiments provided by the present disclosure, Figure 3As shown, a second frame 32 is provided on the second support plate 3, a positioning groove 321 is formed on the second frame 32, and the fixing frame 7 is arranged in the positioning groove 321. In this way, the positioning of the fixing frame 7 by the positioning groove 321 can realize the positioning of the flow battery stack 10, 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 vibration reduction effect of the flow battery stack 10 and improve the safety of the flow battery stack 10.

[0037] According to the embodiment provided by the present disclosure, the fixing frame 7 is made of insulating material. In this way, the electrical safety of the liquid flow battery stack 10 can be ensured. Since there is a high voltage between the battery cells in the liquid flow battery stack 10, the fixing frame 7 for fixing the liquid flow battery stack 10 is made of insulating material to effectively prevent the current from short-circuiting between different battery cells or between the fixing frame 7. At the same time, it can protect personnel and the liquid flow battery stack 10, prevent electric shock accidents when operators touch the fixing frame 7, and ensure the safety of personnel and equipment.

[0038] Below, reference Figures 1 to 5As shown, the present disclosure will combine the above-mentioned specific embodiments to give a detailed introduction to the specific use process of the vibration reduction support device for the liquid flow battery stack 10. When the vibration reduction support device of the present disclosure is used to support the liquid flow battery stack 10, the liquid flow battery stack 10 is placed in the accommodation space between the first sub-frame 71 and the second sub-frame 72, and the connecting arms 74 of the first sub-frame 71 and the second sub-frame 72 are respectively connected along the circumferential direction by the connecting rod 75. The first sub-frame 71 and the second sub-frame 72 are fixed, and the liquid flow battery stack 10 installed on the fixing frame 7 is placed in the second frame 32 of the second support plate 3, and the fixing frame 7 is fixed in the positioning groove 321, so as to realize the positioning of the liquid flow battery stack 10 and the fixing frame 7. When the vibration reduction support device is subjected to external impact, the first support plate 22 vibrates and drives the connecting plate 211 to move downward along the guide rod 11. At this time, the shock-absorbing spring is compressed by the pressure to absorb the vibration energy from the first support plate 22, and elastic deformation occurs to prevent the first support plate 22 from continuing to move downward, so as to achieve the vibration reduction of the liquid flow battery stack 10 in the vertical direction by reducing the vibration of the first support plate 22 in the vertical direction. At the same time, the second support plate 3 shakes relative to the first frame 21, driving the liquid flow battery stack 10 to move. Since the second support plate 3 is connected to a universal wheel, when the second support plate 3 moves in the left-right direction or the front-back direction, the universal wheel can cooperate with the second support plate 3 to move smoothly, reducing the risk of the second support plate 3 losing balance during the movement and causing the liquid flow battery stack 10 to be misplaced. When the second support plate 3 moves in the left-right direction, it can contact the second vibration damper 51, so that the second vibration damper 51 made of elastic rubber undergoes elastic deformation to absorb and dissipate the impact energy between the second support plate 3 and the two sides of the first frame 21 that are relatively arranged in the left-right direction, so as to achieve the vibration reduction of the liquid flow battery stack 10 in the left-right direction by performing vibration reduction treatment on the second support plate 3. When the second support plate 3 moves in the front-to-back direction, it can contact the third vibration damper 61, so that the third vibration damper 61 made of elastic rubber undergoes elastic deformation to absorb the impact energy between the second support plate 3 and the two sides of the first frame 21 that are relatively arranged in the front-to-back direction. Therefore, when the vibration reduction support device of the present application is used to support the liquid flow battery stack 10, the vibration reduction of the liquid flow battery stack 10 in the up-down direction, the left-to-right direction, and the front-to-back direction can be achieved simultaneously.
