[0002] All-vanadium liquid flow battery is a liquid redox battery with vanadium as the active material. Its working principle is based on the electrochemical redox reaction of vanadium ions with different valence states on the electrode surface. This battery uses an external pump to press electrolyte into the battery stack, so that the electrolyte circulates in the closed loop of different storage tanks and half-cells. The electrolyte solution flows parallel to the electrode surface and undergoes electrochemical reactions.

[0043] Both ends of the push-pull rod 1413 are hinged to the slider 1412 and the end block 1404 respectively.

[0044] Working principle of the present invention:

[0045] When the staff places the battery 3 in the placement room of the cabinet 1, and connects the corresponding infusion tube 7 and return tube 10 to the positive and negative poles of the battery 3, after the pipeline is clamped, the pump 5 is started to make the suction tube 6 suck the electrolyte in the liquid storage box 4, and then the corresponding electrolyte is transported to the battery 3 through the infusion tube 7, so that the electrolyte in the battery 3 can flow back to the liquid storage box 4 through the return tube 10, the cooling tank 11 and the lower liquid pipe 12, and the circulating reflux electrolyte can be cooled by the refrigeration plate in the cooling tank 11, so as to ensure that the circulating electrolyte always maintains the optimal temperature.

[0046] When the electrolyte is transported rapidly in the infusion tube 7, under the limiting effect of the electrically-controlled one-way valve 1306, the infusion tube 7 can form a negative pressure in the movable cylinder 1302 through the connecting tube 1304, so that the piston 1303 in the movable cylinder 1302 can move upward under the effect of the negative pressure, thereby allowing the piston 1303 to drive the transmission shaft 1309 to move upward synchronously through the piston rod 1307, and using the position sensor to achieve alternating switching of the electrically-controlled one-way valve 1306 and the electrically-controlled intake valve 1325 as the transmission shaft 1309 moves, thereby enabling the piston 1303 to move back and forth longitudinally in the movable cylinder 1302.

[0047] When the transmission shaft 1309 moves back and forth longitudinally driven by the piston 1303, since the turntable 1311 can drive the driving ring gear 1313 to rotate through the connecting rod 1312, the transmission shaft 1309 can exert the squeezing force on the force-bearing rod 1314 through the spiral slide 1315 during the movement, so that the force-bearing rod 1314 can drive the driving ring gear 1313 to rotate. Through the tooth chain transmission composed of the driving ring gear 1313, the driven ring gear 1318 and the transmission chain 1319, the driving ring gear 1313 can drive the cooling tank 11 to rotate, which is beneficial to improve the cooling effect of the refrigeration plate in the cooling tank 11 on the electrolyte.

[0048] When the cooling tank 11 rotates, since the rotating ring 1407 can rotate on the ring track 1406, the inner ring 1401 can drive the filter screen 1408 to rotate as the cooling tank 11 rotates, which is beneficial for the filter screen 1408 to filter the sediment in the reflux electrolyte. At the same time, when the driving ring teeth 1313 rotate, the driving ring teeth 1313 mesh with the transmission teeth 1416, and the transmission teeth 1416 can drive the reciprocating screw 1411 on the rotating shaft 1410 to rotate synchronously through the linkage rod 1414 during the rotation process, so that the sliders 1412 on the two reciprocating screws 1411 are relatively The two sliders 1412 move in opposite directions. When the two sliders 1412 move toward each other, the two sliders 1412 can drive the end block 1404 to move downward through the push-pull rod 1413, so that the end block 1404 drives the connecting block 1405 to move downward synchronously through the slide bar 1403, which is beneficial to pulling the filter mesh 1408 from a plane shape to a cone mesh shape. Moreover, when the two sliders 1412 move away from each other, the push-pull rod 1413 and the slide bar 1403 can drive the filter mesh 1408 to change from a cone mesh shape to a plane shape. The continuous shape transformation of the filter mesh 1408 is utilized to improve the filtering effect of the filter mesh 1408 on the electrolyte.
