Description

Technical Field

[0001] The utility model relates to the technical field of battery stack disassembly and assembly, and in particular to a battery stack quick disassembly and assembly device for an all-vanadium battery. Background Art

[0002] The all-vanadium battery is a redox battery in which the active material is in a circulating liquid state. The electric energy of the all-vanadium battery is stored in the form of chemical energy in a sulfuric acid electrolyte containing vanadium ions of different valence states. The electrolyte is pressed into the battery stack by an external pump. When the all-vanadium battery is actually produced, an installation device is required to complete the disassembly and assembly of the all-vanadium battery stack. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a battery stack installation device for all-vanadium liquid flow battery processing with publication number: CN212062593U, which includes a bracket, a sliding plate, a rack, a first motor, a gear, a hydraulic push rod, a connecting plate, a limit rod, a clamping arm, a connecting rod, a slide plate, a limit block, a lifting shell, a universal wheel, a second motor and a threaded shaft. All electrical appliances in the device are powered by an external power supply. When the device is used, the device is powered on. The staff first moves the device to the top of the wooden frame where the battery stack is placed by relying on the universal wheel. Then the staff controls the operation of the second motor through an external controller. The operation of the second motor rotates the threaded shaft. Since the threaded shaft is spirally connected to the bracket, the overall height of the bracket is changed when the threaded shaft rotates, and the height of the bracket is lowered. Then the staff starts the hydraulic push rod through the external controller. The hydraulic push rod is extended to move the connecting plate and the limit rod downward. At this time, the connection The connecting rod rotates, reducing the distance between the clamping arms and allowing the slide plate to extend into the bottom of the battery stack. As the distance between the clamping arms decreases, the clamping arms clamp the battery stack, and then the staff moves the battery stack together with the device to the bracket. The staff controls the operation of the second motor through an external controller to adjust the height of the bracket so that the battery stack is aligned with the bracket to be installed. The staff then controls the operation of the first motor through an external controller. The operation of the first motor drives the gear to rotate, and the gear engages the rack to slide the movable plate backward to move the battery stack to the rear end of the bracket. The staff then pushes the battery stack. Since the slide plate is slidably connected to the clamping arm, when the battery stack is pushed, the slide plate enters the bracket together with the battery stack. The staff then holds the battery stack with tools and operates the hydraulic push rod through an external controller to increase the distance between the clamping arms and release the battery stack. The staff then adjusts the position of the battery stack and connects the pipeline.

[0004] The above utility model needs to use two slides to complete the clamping work of the battery stack, and then complete the upward movement of the battery stack through the cooperation of the lifting shell, the second motor and the threaded shaft, and then use the universal wheel to move the battery stack to the installation position for installation. When disassembling and assembling the battery stack in this way, the installation screws on the surface of the battery stack cannot be quickly disassembled, which reduces the disassembly and assembly efficiency of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
