Among them, a fire extinguishing agent storage container in a fire extinguishing system is used to store a fire extinguishing agent, and the fire extinguishing agent storage container is generally a pressure container. Illustratively, the fire suppressant storage container may be a steel seamless gas cylinder or the like of the prior art, and the utility model is not limited thereto. The fire extinguishing agent may be, for example, heptafluoropropane gas in the prior art, or carbon dioxide gas or aerosol in the prior art, which is not limited by the present invention.
The fire detecting pipe in the fire extinguishing system is a detector for detecting the position of a fire source and a pipeline for conveying fire extinguishing medium. The fire-detecting pipe can be a pressurized non-metal hose which is connected with the fire-extinguishing agent storage container through a pressure valve, the fire-detecting pipe is filled with a certain pressure of fire-extinguishing agent during operation and can explode within a preset temperature range, the fire-extinguishing agent filled in the fire-extinguishing agent storage container is released into the battery compartment through an explosion point, and the pressure in the fire-detecting pipe is instantaneously lost to trigger the pressure valve.

Wherein, the pressure valve in the fire extinguishing system is the control part of the fire extinguishing system and is used for controlling the release of the fire extinguishing medium and the pressure regulation during the release. The pressure valve can guarantee the function that the pressure of the fire detection pipe is balanced and unchanged from the starting end to any point at the tail end, and meanwhile, the pressure valve also has the function of safety pressure relief. When the system is opened, the pressure valve is in a closed state; when a fire breaks out, the pressure in the fire detection pipe is instantaneously lost, and the pressure valve connected with the fire detection pipe is opened, so that the fire extinguishing agent is released from the fire extinguishing agent storage container to the fire detection pipe at a preset release pressure, and then is released into the battery compartment from the explosion point of the fire detection pipe.
Or, when a fire occurs, the fire-detecting pipe bursts, the pressure in the fire-detecting pipe is instantaneously lost, and the pressure valve connected with the fire-detecting pipe is opened, so that the fire extinguishing agent is released from the fire extinguishing agent storage container to the release pipe at a preset release pressure, and then is released from the preset position of the release pipe to the battery compartment.
The pressure switch in the fire extinguishing system is equipment for providing signal feedback when the system acts, and the pressure switch can be composed of a body, a inching switch, a piston, a spring and the like. The pressure switch is connected with the fire detection pipe, is generally arranged at the tail end of the fire detection pipe, is closed at ordinary times, and when the fire detection pipe releases gas, the pressure in the fire detection pipe is zero, the pressure switch piston is reset, the switch contact is disconnected, and a high-level signal is sent to the fire-fighting host.
Wherein, an audible and visual alarm in the fire extinguishing system is connected with the pressure switch. When the switch contact of the pressure switch is disconnected, the pressure switch can simultaneously send a high-level signal to the audible and visual alarm. The audible and visual alarm starts to work after receiving a high-level signal sent by the pressure switch, and simultaneously sends out alarm sound and an optical signal to remind an operator of the abnormity of the position.
Specifically, a fire-fighting host in the fire-fighting isolation energy storage system is respectively connected with the sensor system, the cooling system and the fire extinguishing system.
Illustratively, when the fire-fighting host receives high-level signals sent by a temperature sensor in the sensor system and a smoke sensor in the sensor system at the same time, the fire-fighting host sends the high-level signals to a water filling valve in the cooling system to enable the cooling system to work, and cooling water in the water supply device is conveyed into the battery compartment, so that all battery boxes in the battery compartment can be immersed by the cooling water. Specifically, when the fire-fighting host computer receives the high level signal that temperature sensor and smoke transducer sent simultaneously, can confirm that the condition of a fire appears in the battery compartment this moment, but probably because the condition of a fire is not serious yet, do not trigger fire extinguishing systems, make cooling system work this moment, through the mode that cooling water soaks the battery compartment, can reduce the battery module temperature in the battery compartment below the ignition point, put out flame when the condition of a fire is not serious yet.
Illustratively, when the fire-fighting host receives a high-level signal from the BMS in the sensor system, the fire-fighting host sends a high-level signal to a water injection valve in the cooling system, so that the cooling system operates to deliver cooling water from the water supply device into the battery compartment, so that the cooling water can submerge all the battery compartments in the battery compartment. Specifically, when the fire-fighting host computer receives the high level signal that BMS sent, can confirm that there is the fire hazard in the battery compartment this moment, the battery module surface temperature in the battery compartment is too high or the temperature rise speed is too fast this moment. In order to eliminate the fire hazard in the battery compartment and enable the cooling system to work, the temperature of the battery module in the battery compartment can be reduced to be lower than a preset battery temperature threshold value or the temperature rising rate of the battery module in the battery compartment is reduced to be lower than a preset change rate threshold value by soaking the battery compartment with cooling water.
Illustratively, when the fire-fighting host receives a high-level signal sent by a pressure switch in the fire extinguishing system, the high-level signal is sent to a water filling valve in the cooling system, the cooling system is enabled to work, and cooling water in the water supply device is conveyed into the battery compartment, so that all battery boxes in the battery compartment can be immersed by the cooling water. Specifically, when the fire-fighting host receives a high-level signal sent by the pressure switch, the fire condition in the battery compartment can be confirmed, and at the moment, the fire extinguishing gas exists in the battery compartment. The fire extinguishing gas isolates oxygen in the battery compartment to extinguish the flame, but the battery cannot be cooled, the field heat cannot be effectively reduced, and if external oxygen enters, the reignition is easy to occur. Therefore, in order to eliminate the risk of re-ignition and enable the cooling system to work, the temperature of the battery module in the battery compartment can be reduced to be lower than a preset battery temperature threshold value by soaking the battery compartment with cooling water.
Illustratively, when an abnormality occurs in the battery compartment, the cooling process is performed and handled by an operator. The fire-fighting host receives an operation signal input by an operator, and sends a high-level signal to an overflow valve in the cooling system to open the overflow valve, so that cooling water can pass through the overflow valve and be discharged from the battery compartment.

Through setting up the fire control host computer for the energy storage system is kept apart in the fire control can be according to each item data in the battery compartment that sensor system detected, and the work of control cooling system, thereby reduce the temperature of battery cluster in the battery compartment, eliminate conflagration hidden danger. Through setting up fire extinguishing system, can automatic fire extinguishing, solved among the prior art can't carry out the defect that conflagration prevention and condition of a fire were handled to single battery cluster.

In particular, as the cooling water soaks the cell compartment during operation of the cooling system, an electrolytic reaction may occur upon contact of the water with the cell, producing hydrogen and oxygen. Among them, hydrogen is very combustible, and oxygen is one of the combustion conditions, so in order to prevent the risk of re-combustion, it is necessary to judge whether the electrolytic water reaction is performed. Because the air contains a large amount of oxygen, the detection of the oxygen cannot indicate whether the electrolysis process occurs, and in order to save cost, the mode of only detecting the hydrogen can be adopted to judge whether the electrolysis process occurs.
Illustratively, the fire host sends a high signal to the combustible gas detector at the same time as sending a high signal to the fill valve in the cooling system. The combustible gas detector starts to work after receiving a high-level signal sent by the fire-fighting host, and whether the battery compartment contains hydrogen or not is detected. For example, the combustible gas detector may be implemented by detecting combustible gas through an infrared sensor in the prior art, or may be implemented by using a catalytic type combustible gas detector, and the like, which is not limited in the present invention.
As an optional embodiment of the present invention, as shown in fig. 2, the fire protection isolated energy storage system further includes: an exhaust fan 9; a ventilation fan 9 is provided on the surface of the battery compartment 2 and is connected to the combustible gas detector 8 so that the battery compartment 2 is exchanged with the outside air.
Specifically, when the combustible gas detector detects that the battery compartment contains combustible gas, a high-level signal is sent to the exhaust fan. The exhaust fan starts to work when receiving a high-level signal sent by the combustible gas detector, and the combustible gas is discharged out of the battery compartment.
According to the fire-fighting isolation energy storage system disclosed by the utility model, the combustible gas detector and the exhaust fan are arranged, so that the system can effectively discharge the combustible gas in the battery compartment in time, and the risk of reburning is avoided.
