However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0078] A redox battery in which vanadium is the active material in a circulating liquid state.

[0079] Reference Figure 1 and Figure 12-13, an embodiment of the utility model provides an energy storage container. It includes an upper box body 10 and a lower box body 20. In the utility model, the electrolyte and the battery stack are separated by stacking up and down. The battery stack is placed on the upper box body 10, and the electrolyte is stored in the electrolyte storage tank of the lower box body 20. The electrolyte is pressed from the electrolyte storage tank into the upper box battery stack by a pump. Under the action of mechanical power, it circulates in the closed loop of different storage tanks and half-cells. A proton exchange membrane is used as the diaphragm of the battery pack. The electrolyte solution flows parallel to the electrode surface and an electrochemical reaction occurs. The current is collected and conducted through the double electrode plates, so that the chemical energy stored in the solution is converted into electrical energy.

[0080] The upper box body 10 includes an upper frame composed of at least an upper bottom side beam, an upper bottom cross beam 12, an upper top side beam 15, an upper top cross beam, and an upper column. The upper bottom side beam and the upper bottom cross beam 12 can be fixedly connected by welding. Optionally, the upper bottom side beam and the upper bottom cross beam 12 are connected end to end to form a substantially rectangular upper bottom frame. The upper corner pieces are arranged at the corners of the upper frame, and the upper corner pieces can also be fixedly connected to the upper bottom side beams and the upper bottom cross beam 12 by welding. Similarly, the lower box body 20 includes a lower frame composed of at least a lower bottom side beam, a lower bottom cross beam, a lower top side beam 22, a lower top cross beam 21, and a lower column. The lower top side beam 22 and the lower top cross beam 21 can be fixedly connected by welding. The lower corner pieces are arranged at the corners of the lower frame, and the lower corner pieces can also be fixedly connected to the lower top side beam 22 and the lower top cross beam 21 by welding.

[0081] like Figures 2 to 7 As shown, a floor 11 is provided at the bottom of the upper box 10, and the floor 11 is connected to the upper frame. Specifically, the floor 11 is connected to the upper bottom frame. The floor 11 structure is roughly constructed as a rectangle in the horizontal plane, which is adapted to the size and shape of the upper bottom frame. It can be understood that the floor 11 is laid flat on the bottom of the container. Therefore, a flat cargo plane can be formed, which is conducive to the stacking and fixation of the battery stack. Optionally, the floor 11 is a wooden floor 11, so as to ensure the insulation effect and avoid affecting the liquid flow battery system. Optionally, multiple floors 11 are spliced ​​along the horizontal and / or longitudinal direction of the upper box 10, and the floor 11 is detachably connected to the upper box 10. In the utility model, the floor 11 is arranged separately. As can be seen from the above, the electrolyte storage tank is connected to the battery stack by a pipeline. Therefore, the floor 11 at the corresponding position can be directly removed where the pipeline needs to be penetrated. As shown in FIG. Figure 2 and Figure 4 As shown, optionally, at least part of the floor panels 11 are spaced apart to form mounting grooves 111 for pipes to pass through.

[0082] The container provided by the utility model has high integration and strong flexibility.

[0083] In some embodiments of the utility model, two adjacent floors 11 along the longitudinal direction DL form a transverse seam 112. Correspondingly, the upper box body 10 further includes a plurality of upper bottom cross beams 12 extending in the transverse direction and spaced in the longitudinal direction DL, the upper bottom cross beams corresponding to the transverse seams 112 one by one, and the upper bottom cross beams 12 are supported below the transverse seams 112. By setting the upper bottom cross beams 12 and the transverse seams 112 one by one, the upper bottom cross beams 12 can effectively support each floor 11. The upper bottom cross beams 12 are supported below the transverse seams 112 and are connected to the structure formed with the floor 11. Therefore, the upper bottom cross beams 12 not only provide support, but also provide a structural basis for the installation of the floor 11, ensuring that the floor 11 is firmly connected inside the container.

[0084] like Figure 6 As shown, in some embodiments of the present invention, the floor 11 is provided with a fixing seat 113, and the fixing seat 113 is used to install the fastener 13, so that the floor 11 is connected to the upper bottom cross beam 12 through the fixing seat 113. The fixing seat 113 can provide a reliable connection point between the floor 11 and the upper bottom cross beam 12, and a firm mechanical connection is formed through the installation of the fastener 13. This avoids the loss of the floor 11 due to frequent disassembly and prolongs the service life of the floor 11. In addition, through the reliable connection between the fixing seat 113 and the upper bottom cross beam 12, the shaking and displacement of the floor 11 are reduced.

[0085] In some embodiments of the present invention, the floor 11 is provided with a handle 114. The handle 114 is provided to facilitate the staff to grasp and lift the floor 11, simplify the handling and installation process of the floor 11, and optimize its detachable effect.

[0086] like Figure 3 and Figure 7 As shown, in some embodiments of the present invention, the upper box 10 further includes a mounting bracket 14, which is detachably mounted to the upper box 10. Optionally, the mounting bracket 14 can be used to install a battery pack or other equipment.

The upper bottom cross beam 12 extends along the transverse direction DW and is spaced along the longitudinal direction DL.

A fixing column 16 is arranged at the bottom of the upper box body 10, and the fixing column 16 is connected to the upper bottom cross beam 12. Optionally, the fixing column 16 passes through the floor 11 and is fixedly connected to the upper bottom cross beam 12 to install the mounting bracket. The fixing column 16 extends along the height direction DH of the upper box body 10, and a plurality of fixing columns 16 are spaced along the longitudinal direction DL. That is, a plurality of fixing columns 16 are arranged side by side in the extension direction of the upper top side beam 15. Among them, the fixing column 16 and the upper top side beam 15 are spaced along the height direction DH of the upper box body 10, and the mounting bracket 14 is connected between the upper top side beam 15 and the fixing column 16. The fixing column 16 provides a connection point for the mounting bracket 14. The fixing column 16 extends along the height direction DH of the upper box body 10 , and thus can provide a stable support for the mounting bracket 14 , thereby further enhancing the rigidity and bearing capacity of the overall structure of the upper box body 10 .

[0088] Optionally, the fixing column 16 passes through the floor 11 and is fixedly connected to the upper bottom beam 12, so the fixing column 16 corresponds to the upper bottom beam 12. Optionally, the same upper bottom beam 12 can correspond to multiple fixing columns 16. The fixing columns 16 can provide spaced transverse and longitudinal installation points.

[0089] In some embodiments of the present invention, the mounting bracket 14 is connected to the upper top side beam 15 via a fastener 13. The mounting bracket 14 is connected to the fixing column 16 via a fastener 13. In the present invention, the fastener 13 includes but is not limited to bolts and rivets.
