Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, in particular to a charging device for an all-vanadium redox flow battery. Background Art

[0002] The all-vanadium liquid flow battery is a liquid redox battery with vanadium as the active material. Its operating principle is based on the electrochemical redox reaction of vanadium ions of different valence states on the electrode surface. This battery uses an external pump to press the electrolyte into the battery stack, so that the electrolyte circulates in a closed loop of different storage tanks and half-cells. The electrolyte solution flows parallel to the electrode surface and undergoes electrochemical reactions. The current is collected and conducted through the double electrode plates, thereby converting the chemical energy stored in the solution into electrical energy. The positive and negative electrolytes of the all-vanadium liquid flow battery are stored in their own storage tanks. When the battery is charged and discharged, the positive and negative electrolytes undergo redox reactions on both sides of the ion exchange membrane, maintaining the ion concentration and realizing the charging and discharging of the battery.

[0003] The all-vanadium liquid flow battery charging device is a device used to charge the all-vanadium liquid flow battery. When charging the all-vanadium liquid flow battery, the all-vanadium liquid flow battery is placed in a charging cabinet for charging. Currently, a cooling fan is installed on the top of the charging cabinet, and air holes are installed at the front and rear doors to dissipate heat when the all-vanadium liquid flow battery is charging. However, this method cannot provide emergency auxiliary heat dissipation inside the charging cabinet. When the cooling fan cannot meet the heat dissipation requirements of the charging cabinet, the charging effect of the all-vanadium liquid flow battery will be affected. Therefore, it is necessary to design an all-vanadium liquid flow battery charging device to solve the above problems.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0033] By means of the above-mentioned emergency auxiliary heat dissipation mechanism, the internal temperature of the vanadium battery charging cabinet 1 is monitored by the temperature sensor 4. When the internal temperature of the vanadium battery charging cabinet 1 is higher than the set value, the controller 5 starts the electric telescopic rod 7 to open both door bodies 3. In this way, the front and rear openings of the vanadium battery charging cabinet 1 are exposed, thereby increasing the heat dissipation area inside the vanadium battery charging cabinet 1. Heat is dissipated by the cooling fan inside the vanadium battery charging cabinet 1. In this way, the heat dissipation inside the vanadium battery charging cabinet 1 can be carried out urgently and quickly. After the internal temperature of the vanadium battery charging cabinet 1 is lower than the set value, the two door bodies 3 can be controlled to close. Subsequently, when it is necessary to manually open the front door or the rear door, the corresponding hand-held rod 14 is pulled to place the main block 9 and the auxiliary block 10 in the placement box 15. At this time, the front door or the rear door can be manually opened for operation, which is more convenient to switch.

[0034] Specifically, a cooling fan is installed on the top of the vanadium battery charging cabinet 1, and an air hole is opened on the door body 3. An all-vanadium liquid flow battery is placed in the vanadium battery charging cabinet 1. It should be noted that the cooling fan is used to dissipate heat inside the vanadium battery charging cabinet 1. It is not shown in the figure and is embedded in the top of the vanadium battery charging cabinet 1 and connected to the outside world.

[0035] Specifically, a temperature sensor 4 and a controller 5 are fixedly installed on the vanadium battery charging cabinet 1. The temperature sensor 4 is connected to the inside of the vanadium battery charging cabinet 1. The temperature sensor 4 and the electric telescopic rod 7 are both electrically connected to the controller 5. It should be noted that the internal temperature of the vanadium battery charging cabinet 1 is monitored by the temperature sensor 4. When the internal temperature of the vanadium battery charging cabinet 1 is higher than the set value, the controller 5 starts the electric telescopic rod 7.

[0036] Specifically, the front and rear sides of the push plate 8 are in contact with the connecting plate 6, a main groove 11 is provided on the top of the push plate 8, the main block 9 is clamped with the main groove 11, a hand-held rod 14 is fixedly provided on the top of the main block 9, an auxiliary groove 12 is provided on the top of the push plate 8, an auxiliary groove 2 13 is provided on the top of the connecting plate 6, the auxiliary block 10 is clamped with the auxiliary groove 12 and the auxiliary groove 2 13, the main groove 11 is connected with the auxiliary groove 1 12, and the auxiliary groove 1 12 is connected with the auxiliary groove 2 13. It should be noted that it is convenient to connect and limit the connecting plate 6 and the push plate 8.

[0037] Specifically, two placement boxes 15 are fixedly provided on the side of the push plate 8. It should be noted that the main block 9 and the auxiliary block 10 can be placed in the placement boxes 15 for storage after being taken out.

[0038] Specifically, two door holes 2 are opened on the side of the vanadium battery charging cabinet 1, and the door body 3 is installed in the door hole 2 for horizontal sliding. Adsorption magnets 16 are embedded on the side of the door body 3 and the side wall of the vanadium battery charging cabinet 1. The two adsorption magnets 16 are adsorbed on each other. It should be noted that the stability of the door body 3 after closing can be improved.

[0039] Working principle:

[0040] S1: When the all-vanadium redox flow battery is normally charged, the heat dissipation of the all-vanadium redox flow battery is carried out through the cooperation of the cooling fan and the air holes on the door body 3;

[0041] S2: The internal temperature of the vanadium battery charging cabinet 1 is monitored by the temperature sensor 4. When the internal temperature of the vanadium battery charging cabinet 1 is higher than the set value, the controller 5 starts the electric telescopic rod 7, and the electric telescopic rod 7 drives the push plate 8 to move. The push plate 8 drives the connecting plate 6 to move through the main block 9 and the auxiliary block 10, and the connecting plate 6 drives the door body 3 to move, so that both door bodies 3 are opened. In this way, the front and rear openings of the vanadium battery charging cabinet 1 are exposed, thereby increasing the heat dissipation area inside the vanadium battery charging cabinet 1. The heat is dissipated by the cooling fan inside the vanadium battery charging cabinet 1. In this way, the heat dissipation inside the vanadium battery charging cabinet 1 can be urgently and quickly performed. After the internal temperature of the vanadium battery charging cabinet 1 is lower than the set value, the two door bodies 3 are controlled to close;

[0042] S3: When the front door or the rear door needs to be opened manually later, the corresponding hand-held rod 14 is pulled, so that the main block 9 drives the auxiliary block 10 to move upward, and then the main block 9 can be moved out of the main groove 11, and the auxiliary block 10 can be moved out of the auxiliary groove 12 and the auxiliary groove 2 13, and the limit of the connecting plate 6 and the push plate 8 is released. Then the main block 9 and the auxiliary block 10 are placed in the placement box 15. At this time, the front door or the rear door can be manually opened for operation, and switching is more convenient.
