Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of energy storage battery, especially, relate to a kind of adjustable overflow assembly and liquid flow battery system. BACKGROUND
[0002] The liquid flow battery system is a kind of electrochemical energy storage system, which mainly transports electrolyte into the place of electrochemical reaction, i.e., the electric pile, by the action of pump, and realizes the function of charging and discharging under the action of external electric field. During the electrochemical reaction process, vanadium ions gradually diffuse from the negative electrode to the positive electrode and accumulate during the charging and discharging cycle of the liquid flow battery, and a certain osmotic pressure is generated to promote water migration. In addition, the hydrated hydrogen ions participating in the reaction also cause water migration. Therefore, during the charging and discharging cycle of the liquid flow battery, the electrolyte of the negative electrode usually gradually migrates to the positive electrode, affecting the capacity of the energy storage system. Currently, the overflow pipe is usually arranged between the positive electrode storage tank and the negative electrode storage tank to solve the problem of migration of the negative electrode electrolyte to the positive electrode, so as to slow down the capacity decay rate of the energy storage system.
[0003] However, in order to achieve the overflow effect, the overflow pipe needs to be installed below the actual liquid level of the storage tank. Since the existing storage tank has processing deviation, assembly deviation and deformation after filling, the actual liquid level of the positive electrode storage tank and the negative electrode storage tank cannot be accurately estimated before filling, and the overflow pipe is usually a prefabricated component. Once the storage tank is filled with electrolyte, it is not possible to match the actual liquid level of the storage tank by replacing the overflow pipe. Therefore, after the storage tank is filled with electrolyte to the theoretical capacity, if the liquid level of the storage tank is lower than the preset position of the overflow pipe, it is necessary to add electrolyte to the storage tank to make the liquid level of the storage tank reach the preset position of the overflow pipe. However, for common MWh-level product systems, the above-mentioned method of adding electrolyte to the storage tank to make the liquid level of the electrolyte in the storage tank reach the overflow liquid level has high cost, which easily causes great additional cost burden to the liquid flow battery enterprise.

[0043] Please refer to Figure 1 、 Figure 2 and Figure 6 In some embodiments, the adjustable overflow assembly further comprises a three-way joint 4 and an air pipe 5, the first joint 41 of the three-way joint 4 is rotationally connected with the first connecting pipe 11, the second joint 42 of the three-way joint 4 is rotationally connected with the third connecting pipe 21, the third joint 43 of the three-way joint 4 is connected with the first end of the air pipe 5, and the second end of the air pipe 5 is connected with the top of the first storage tank 10 or the second storage tank 20. In this embodiment, the first overflow pipe 1 and the second overflow pipe 2 are rotationally connected through the three-way joint 4, so that the first overflow pipe 1 and the second overflow pipe 2, which are in communication with each other, constitute a U-shaped overflow assembly capable of swinging within a certain height range, and only by adjusting and positioning the swing positions of the first swing pipe 13 and the second swing pipe 23 through the adjusting mechanism 3. At the same time, the air pipe 5 is connected to the third joint 43 of the three-way joint 4, and only by connecting the end of the air pipe 5 away from the three-way joint 4 with the top of the first storage tank 10 or the second storage tank 20, the air pressure inside the three-way joint 4 can be balanced with the air pressure inside the first storage tank 10 or the second storage tank 20, so that the electrolyte in the first storage tank 10 or the second storage tank 20 can overflow effectively and reliably, and the pressure build-up phenomenon caused by the negative pressure in the first storage tank 10 or the second storage tank 20 can be avoided. It should be noted that the air pipe 5 can be but is not limited to a hose, and the three-way joint 4 can be but is not limited to a variable-diameter three-way socket joint.

In use, only the locking of the sliding piece 34 by the first locking piece 35 needs to be released, and the adjusting rod 32 is rotated around the rotating piece 33 as the rotation axis. At the same time, the circular arc-shaped sliding groove or the circular arc-shaped sliding hole 311 on the adjusting base 31 limits the corresponding movement of the sliding piece 34 along a circular arc-shaped track, so that the adjusting rod 32 can drive the first overflow pipe 1 and the second overflow pipe 2 connected with each other to swing within a certain height range, thereby adjusting the height position of the first overflow pipe 1 and the second overflow pipe 2. After the first overflow pipe 1 and the second overflow pipe 2 are adjusted to the height position at which the electrolyte in the first tank 10 or the second tank 20 can flow, the sliding piece 34 is locked on the adjusting base 31 by the first locking piece 35, so that the first overflow pipe 1 and the second overflow pipe 2 can be positioned at the height position at which the electrolyte in the first tank 10 or the second tank 20 can flow, thereby ensuring that the electrolyte in the first tank 10 or the second tank 20 can overflow effectively and reliably without adding electrolyte into the first tank 10.
