Embodiment Construction
[0044] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0045] see Figure 1 to Figure 10 A vanadium battery stack, comprising an upper end plate 41, a lower end plate 42, a pull rod 44, a liquid flow frame 43, an upper end plate 41, and a lower end plate 42 respectively sandwiched between the upper and lower ends of the stacked liquid flow frame 43, and the upper end plate 41 There are slots 47 evenly distributed on the edge of the lower end plate 42, and the slots on the upper end plate 41 and the lower end plate 42 correspond one-to-one along the thickness direction of the liquid flow frame, and each pair of slots 47 corresponding to the upper and lower sides is provided with a pull rod 44, the pull rod 44 is arranged along the thickness direction of the liquid flow frame 43; the two ends of the pull rod 44 ...

The invention discloses a vanadium cell stack. Recesses are evenly distributed on the edges of an upper end plate and a lower end plate; a pull rod is clamped in each pair of recesses which corresponds to each other up and down; each pull rod extends out of two ends of the upper end plate and the lower end plate; at least one end is provided with an elastic compacting component for compacting the cell stack along the height direction of the cell stack; positioning through holes through which positioning shafts pass are formed in a liquid flow frame and the lower end plate; and detachable claw-like shaft sleeves with adjustable elasticity for positioning and fixing the positioning shafts are fixed at the positions of the positioning through holes. In the implementation process of the assembly technology of the vanadium cell stack, the positions of adjusting nuts only need to preset and adjust; springs are overcome by a tool to push guide sleeves in the elastic compacting component for a certain distance towards the direction far away from the liquid flow frame; the distance between two guide sleeves on each pull rod is greater than the height of the cell stack; the pull rod is embedded into the recesses in the upper end plate and the lower end plate; and the adjusting nuts do not need to gradually adjust in the assembly process, so that the installation accuracy and efficiency are high; and a lot of time is saved.
Description
technical field [0001] The invention relates to the technical field of vanadium batteries, in particular to a vanadium battery stack and an assembly process thereof. Background technique [0002] Vanadium redox flow battery energy storage technology has become one of the preferred technologies for large-scale energy storage due to its outstanding advantages such as long service life, large scale, safety and reliability. An iron bar perpendicular to the lower end plate is positioned against the periphery of the liquid flow frame during the assembly process. The iron bar cannot be lifted and lowered so that it cannot be positioned at the end of the installation, and it is difficult to ensure that the four iron bars are in line with the lower end plate. verticality, Chinese patent 201110327878.2 discloses a vanadium battery stacking method and a vanadium battery stacking device. The stack device is provided with a lower template and a lower pressing member for carrying the stac...
