Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power stations, in particular to an energy storage power station lithium-ion battery assembly with a safety mechanism and a protection system thereof. Background Art

[0042] A protection system includes a communication module, a data module and a control module. The temperature drop information of the temperature sensor 150 is transmitted to the data module through the communication module. The data module collects and analyzes the data and then transmits it to the control module. The control module controls the electric telescopic rod 11 and the cooling fan 17 to respond.

[0043] When installing the battery body 2, push the driving connecting plate 3 in the direction of the supporting fixing plate 15. As the driving connecting plate 3 moves, the movable connecting strip 4 will be driven to move in opposite directions under the action of the connecting inclined hole 32. At this time, the battery body 2 can be plugged into the plug-in installation hole 151 and supported by the supporting movable plate 7. Then, the driving connecting plate 3 can be released to reset the driving connecting plate 3 under the action of the reset spring 34. In this way, the limiting top plate 44 can be pressed on the upper end of the battery body 2 to achieve fixed installation of the battery body 2. The operation is simple, convenient and fast. During the operation of the battery body 2, the temperature sensor 150 detects the temperature of the battery body 2. When the temperature of the battery body 2 is too high, the electric telescopic The rod 11 is extended, and the cooling fan 17 increases the wind force to dissipate heat. In the process of the electric telescopic rod 11 extending upward, the two bearing movable plates 7 will be driven to move away from each other under the action of the first matching connecting rod 61. As the bearing movable plates 7 move away from each other, the matching movable blocks 833 will contact the inner walls on both sides of the energy storage power station box 1, restricting the matching movable blocks 833 so that they can no longer move. In this way, as the bearing movable plate 7 continues to move, the third matching connecting rod 832 will push the movable serial block 8 to move, and then the bearing matching plate 5 will be driven to move toward the direction of the battery body 2 under the action of the movable serial block 8, so that the bearing plug block 52 on the bearing matching plate 5 is plugged into the battery body 2. The load-bearing socket 21 supports the battery body 2. At this time, the load-bearing movable plate 7 is completely separated from the battery body 2, so that the lower end surface of the battery body 2 is exposed, which can better dissipate heat and ensure its heat dissipation strength. In addition, the electric telescopic rod 11 will drive the dust cover 9 to move under the action of the second matching connecting rod 62 during the upward extension process, so that the heat dissipation holes 91 on the dust cover 9 are more exposed on the outside of the plug-in connecting groove 141, so that the heat dissipation capacity can be better enhanced. When the battery body 2 does not need a larger heat dissipation strength, the heat dissipation holes 91 are more in the plug-in connecting groove 141, which can also better reduce the external dust from entering the energy storage power station box 1. When the temperature of the battery body 2 drops, The wind force of the cooling fan 17 decreases to avoid waste of resources. At the same time, the electric telescopic rod 11 retracts downward to drive the driving carrier plate 6 to move downward. As the driving carrier plate 6 moves downward, the first matching connecting rod 61 will drive the bearing movable plate 7 to move toward each other so that the bearing movable plate 7 is reset, and the battery body 2 can be supported again. At the same time, as the bearing movable plate 7 moves, the bearing matching plate 5 will also be reset, so that the bearing plug block 52 is no longer inserted in the bearing socket 21, which facilitates the disassembly of the battery body 2. At the same time, as the driving carrier plate 6 moves downward, the dust cover 9 is also reset under the action of the second matching connecting rod 62. When the battery body 2 needs to be disassembled, the driving connecting plate 3 is also pushed in the direction of the bearing fixed plate 15.Under the action of the connecting oblique hole 32, the movable connecting bar 4 is driven to move back again, so that the limiting top plate 44 is no longer pressed on the battery body 2, so that the battery body 2 is in an unlocked state and can be quickly removed, which is simple, convenient and fast to operate.
