FIRE PROTECTION FLUID STORAGE DEVICE FOR BATTERY PACK

The present application is provided with a fluid storage apparatus of a battery pack, including: a box, where the box has an inner cavity; a partition member, where the partition member is located in the inner cavity of the box, and the partition member divides the box into a fluid storage portion and a gas storage portion. The fluid storage portion is used to store spraying liquid and the fluid storage portion has a fluid outlet; the gas storage portion is used to store gas and the gas storage portion has a fluid inlet. And the partition member is configured to move toward the fluid outlet under the action of compressed gas in the gas storage portion. When the spraying liquid in the liquid storage portion is discharged from the fluid outlet, the thrust of the spraying liquid on the partition member is reduced, then under the thrust of the compressed gas in the gas storage portion, the spraying liquid is configured to be driven to move toward the direction of the fluid outlet by the partition member, so that the fire-fighting fluid is discharged continually from the fluid outlet, thereby realizing the function of thrusting the fire-fighting fluid with the compressed gas. At the same time, the fire-fighting fluid storage apparatus also has advantages such as simple structure and easy to fit with surrounding components for bonding.
