and 5, operating the water fire-fighting system. After the battery system finishes spraying the heptafluoropropane through the heptafluoropropane fire-fighting system in the step 4, waiting for the inerting of the fire extinguishing agent for a certain time, if the control center still detects the temperature abnormality and smoke abnormality in the battery system, the alarm system still gives an alarm, a worker needs to observe the situation in the abnormal area of the battery system through a monitoring screen arranged on the fire-fighting cabinet or the ship cab alarm center, and if the naked fire or the fire re-combustion is still visible, the worker needs to manually press a manual button in the fire-fighting cabinet to start the water fire-fighting system.
After the control center receives a signal for starting the water fire-fighting system, the control center definitely determines the number of battery frames where the abnormal lithium battery pack is located according to the currently detected abnormal area of the battery system, an electric water spray head of a transverse water pipe of a corresponding layer is started, and water in the water pipe carries out cooling and secondary fire-extinguishing operation on the layer where the abnormal lithium battery pack is located through the water spray head.
At the moment, the staff still needs to continuously observe the monitoring screen in the abnormal area of the battery system, so that after the fire disaster is extinguished, the staff manually presses a manual button in the fire control cabinet to finish the water fire control operation; if the fire disaster in the current abnormal area is found to continue, but the control center does not give an alarm any more because of unknown reasons, and the water fire control system is not successfully started, the manual/automatic switching module in the fire control cabinet is shifted, the fire control system is manually controlled, then the manual button in the fire control cabinet is pressed down, forced water fire control operation is started in the independent area where the abnormal lithium battery pack is located, all water spray heads in the area are started, the fire disaster is eliminated, and the safety of ships is ensured.
After the water fire-fighting operation is finished, fire-fighting water in an independent area where the abnormal lithium battery pack in the battery system is located flows out through a water outlet arranged at the bottom of the container, so that the faults of short circuit and the like of electric equipment caused by accumulation of the fire-fighting water are avoided.
