Description
Technical Field

[0002] With the promotion and application of new energy sources such as solar and wind power, energy storage technology has also developed. Lithium batteries have gradually become the mainstream energy storage product due to their advantages such as high energy density, long service life, high rated voltage, high power handling capacity, low self-discharge rate, light weight, green and environmentally friendly properties, and minimal water consumption during production.
[0003] The charge-discharge cycle life and safety of lithium-ion batteries are greatly affected by temperature. When the cell temperature is too high or the temperature difference is large, the cell cycle life will decrease significantly, affecting the service life of energy storage products. In severe cases, it can lead to thermal runaway of the cell.

[0005] Existing energy storage systems for pressurized gas fire suppression require not only exhaust vents to release thermally runaway combustible gases, volatiles in the cabin, and subsequent extinguishing agents, but also separate pressure relief windows to prevent excessive pressure after the extinguishing agent is sprayed, which could cause the container doors and partitions to break under pressure, rendering them ineffective as fire barriers.

[0042] Further, the edge of the baffle support on the side facing the window frame is provided with a surrounding barrier;
[0043] The top of the pressure relief baffle is provided with a water baffle, which is matched with the surrounding barrier on the top of the baffle support.
[0044] From the above description, the edge of the baffle support is provided with a surrounding barrier, which is matched with the water baffle on the top of the pressure relief baffle, forming a double waterproof structure to improve the waterproof capability.
[0045] Further, the baffle support is rectangular, and the surrounding barriers on the two sides near the top of the baffle support are provided with notches, and the connecting line of the notches on the two sides is parallel to the top of the baffle support.
[0046] The baffle support is connected with the rotating shaft through the notches.
[0047] From the above description, the notches of the surrounding barrier are connected with the rotating shaft, so that the rotating shaft can drive the surrounding barrier to rotate, and the notches are arranged on the two sides near the top of the baffle support instead of being directly connected with the rotating shaft from the top of the surrounding barrier, which can improve the waterproof performance.
[0048] Further, the elastic member is a spring telescopic column.
[0049] The baffle support is provided with through holes corresponding in number and position to the spring telescopic columns.
[0050] One end of the spring telescopic column passes through the through hole, and a limiting member larger than the through hole is arranged on the end head.
[0051] From the above description, the spring telescopic column is used as the elastic member, and the compression stroke and spring stiffness can be customized according to the set pressure relief pressure. When the internal pressure reaches the threshold value, the spring is compressed to make the pressure relief baffle gap, realizing rapid pressure relief. Compared with the traditional rupture disc structure, the spring telescopic column can be reused, and the maintenance cost is reduced.

[0059] Further, the waterproof baffle support is provided with a waterproof magnetic sealing ring around the pressure relief port.
[0060] As can be seen from the above description, the waterproof magnetic sealing ring can still be attracted and closed by the baffle through magnetic force when the spring tension is weakened, thereby ensuring the waterproof performance.
[0061] Further, it further comprises a mounting protection plate, which is mounted on the air inlet surface of the window frame.

[0063] The mounting protection plate is provided with an air inlet mesh at a position corresponding to the exhaust fan.
[0064] As can be seen from the above description, the mounting protection plate and the partition plate are arranged to physically isolate the exhaust fan and the driving device. The air inlet mesh of the protection plate can block foreign matters from entering and protect the fan impeller. The partition plate separates the electrical components and the airflow channel, avoids corrosion by corrosive gas, and prolongs the service life of the driving device.

[0072] The baffle support 3 is installed on the air outlet surface of the window frame 1, and can be turned outward by a rotating shaft 6 to open the exhaust passage. The pusher 5 is connected with the rotating shaft 6, and the rotating shaft 6 is driven to rotate by the pusher 5, so as to drive the baffle support 3 to turn over.

The internal pressure of the container is quickly released to the outside space through the gap, preventing the gas pressure from exploding the partition wall and the door panel of the container, thereby protecting the container.

When the exhaust port is closed, if the internal pressure is too high, the pressure relief baffle will be opened to a certain gap outward under the push of the internal pressure, so that the internal pressure can be released to the outside. The integration of the exhaust window and the pressure relief window is realized, the space requirement for installation is reduced, and the material cost and construction cost are effectively optimized.
