[0026] Please see Figure 1-3 A sealing structure for a flow battery includes a housing 1, a cover 2, and a reinforcing component. The cover 2 is installed on the top of the housing 1, and a reinforcing component is provided on the outside of the connection between the two.

[0027] The reinforcement assembly includes two reinforcement shells 7, which are installed on the outside of the connection between the box body 1 and the cover 2, and are fixedly connected to each other.

[0028] In this embodiment, the top of the box body 1 and the bottom of the cover body 2 are both set in a stepped shape and are interlocked with each other. The outer sides of the top of the box body 1 and the bottom of the cover body 2 are respectively provided with a first connecting block 101 and a second connecting block 201.

[0029] It should be noted that this stepped design not only facilitates precise docking of the two parts, but also initially fixes the relative positions of the box 1 and the cover 2 through the plug-in connection, providing a good foundation for subsequent connection and reinforcement. The stepped plug-in structure also increases the contact area, which helps to disperse stress and improve the stability of the connection.

[0030] In this embodiment, both the first connecting block 101 and the second connecting block 201 are annular blocks, and multiple circumferentially distributed first mounting grooves 102 and second mounting grooves 202 are respectively provided on the end faces of the two blocks that are far away from each other.

[0031] It should be noted that the design of the annular block ensures that the connecting blocks are evenly distributed around the housing 1 and the cover 2, thereby providing uniform support and fixing force. The circumferentially distributed mounting grooves provide accurate positioning and guidance for the installation of the first screw 3, simplifying the installation process and improving installation accuracy.

[0032] In this embodiment, the second mounting groove 202 is internally threaded with a first screw 3, and the bottom end of the first screw 3 extends into the first mounting groove 102 and is bolted with a first nut 4.

[0033] In this embodiment, an installation groove is provided on the top of the box 1 and near its stepped corner. The installation groove is an annular groove, and multiple small inserts 5 distributed in a circle are welded on its top. A sealing ring 6 is inserted into the installation groove. Multiple fixing holes are provided in the sealing ring 6 and are inserted into the small inserts 5.

[0034] It should be noted that the design of the annular groove and the small insert 5 provides a stable support and positioning for the sealing ring 6, ensuring the reliability of the sealing effect. The fixing hole in the sealing ring 6 and the insertion of the small insert 5 further enhance the fixing effect of the sealing ring and prevent loosening or leakage caused by vibration or pressure changes.

[0035] In this embodiment, two reinforcing shells 7 are snapped onto the outside of the first connecting block 101 and the second connecting block 201, and both are welded with fixing blocks 9 at one end close to each other. A third screw 10 is threadedly connected and fixed between two adjacent fixing blocks 9. Two sets of threaded through holes are opened on the outside of the reinforcing shell 7. The two sets of threaded through holes are symmetrically distributed vertically, and multiple are arranged in each circumferential distribution.

[0036] It should be noted that the snap-fit ​​design of the reinforced shell 7 simplifies the installation process, while the fastening connection between the fixing block 9 and the third screw 10 provides additional reinforcement.

[0037] In this embodiment, multiple circumferentially distributed threaded holes are provided on the outer sides of both the box body 1 and the cover body 2. The number, arrangement and size of the threaded through holes and the threaded holes are completely consistent. The threaded through holes and the threaded holes are connected in sequence by a second screw 8.

[0038] It should be noted that the reinforcing shell 7 is connected to the threaded holes on the outside of the box body 1 and the cover body 2 by the second screw 8, which further reinforces the overall structure.

[0039] Beneficial effects:

[0040] The sealing structure for this flow battery effectively enhances the strength and stability of the connection by employing a stepped interlocking design for the housing 1 and cover 2, combined with the annular arrangement of the first connecting block 101 and the second connecting block 201, and the tight connection of the first screw 3 and the first nut 4. Simultaneously, the annular groove on the top of the housing 1 and the interlocking of the small insert 5 with the sealing ring 6 further improve the sealing performance and prevent electrolyte leakage. Furthermore, two reinforcing shells 7 are snapped onto the outside of the first connecting block 101 and the second connecting block 201, and secured between the fixing blocks 9 by the third screw 10, forming a double reinforcement effect that significantly improves the overall structural stability and sealing reliability.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
