[0023] Figure 1 It is a schematic structural diagram of the energy storage cabin fire control system based on perfluorinated hexanone and liquid nitrogen in an embodiment proposed by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] Refer to Figure 1 , a kind of energy storage cabin fire control system based on perfluorinated hexanone and liquid nitrogen proposed by the present invention is applied to an energy storage station. Each energy storage station includes multiple energy storage cabins, each energy storage cabin includes multiple battery clusters, and each battery cluster includes multiple battery packs, and includes: a detection mechanism, a control mechanism, a perfluorinated hexanone fire extinguishing mechanism, a liquid nitrogen explosion suppression mechanism, and a pipe network mechanism;

[0026] Among them, the control mechanism includes a station-level fire control host and multiple fire control hosts. The multiple fire control hosts are used to be installed in multiple energy storage cabins one by one, and the multiple fire control hosts are respectively connected to the station-level fire control host through a communication bus;

[0027] The detection mechanism is used to obtain the status parameters of each energy storage cabin, each battery cluster, and each battery pack;

[0028] Each fire control host is used to perform hierarchical early warning according to the status parameters of each energy storage cabin, each battery cluster, and each battery pack and a preset hierarchical early warning strategy; among them, the levels of early warning include first level, second level, and third level;

[0030] The present invention can timely detect abnormal conditions in the operation of each energy storage cabin, each battery cluster, and each battery pack through the detection mechanism, and realize hierarchical fire early warning; and when the level of early warning is the third level, the station-level fire control host and the fire control host control the perfluorinated hexanone fire extinguishing mechanism, the liquid nitrogen explosion suppression mechanism, and the pipe network mechanism to extinguish fire and suppress explosion on a certain battery pack, battery cluster, or energy storage cabin according to a preset fire extinguishing strategy, effectively avoiding reignition and improving the fire safety of the energy storage station.

[0031] The perfluorinated hexanone fire extinguishing mechanism in this embodiment is a pump-type perfluorinated hexanone fire extinguishing mechanism. The fire extinguishing agent in the pump-type perfluorinated hexanone fire extinguishing mechanism is the FK5112 perfluorinated hexanone fire extinguishing agent. Due to the endothermic effect of the FK5112 perfluorinated hexanone fire extinguishing agent itself, it can cool the entire cabin / cluster / battery pack. At high temperatures, perfluorinated hexanone decomposes to achieve chemical fire extinguishing. Moreover, FK5112 has no corrosion on common metals such as carbon steel, copper, aluminum, stainless steel and other materials, will not damage electronic components and circuits, and will not cause secondary damage. The most important thing is that FK5112 can be used in occupied places. The perfluorinated hexanone (FK5112) fire extinguishing agent is a transparent, colorless, odorless, insulating liquid environmental protection and clean fire extinguishing agent.

[0032] In this embodiment, the detection mechanism includes multiple battery pack detection components, multiple cluster-level detection components, and multiple cabin-level composite detection components;

[0034] Among them, each battery pack detection component has a unique ID number to facilitate the fire control host to identify the battery pack where the early warning occurs.

[0035] Among them, each battery pack detection component includes a CO sensor, a VOC sensor, a smoke sensor, a temperature sensor and an H2 sensor; among them, each cluster-level detection component includes a cabin-level combustible gas detector, an explosion-proof point-type smoke detector and an explosion-proof point-type temperature detector; among them, the cabin-level composite detection and sensing component includes a cabin-level combustible gas detector, an explosion-proof point-type smoke detector and an explosion-proof point-type temperature detector.

[0036] Specifically, the explosion-proof point-type smoke detector and the explosion-proof point-type temperature detector are coded types, and the number of each type of detector is not less than 2.

[0037] Specifically, the cabin-level / cluster-level combustible gas detector is explosion-proof and has the functions of detecting CO, VOC, smoke, temperature and H2.

[0038] In this embodiment, a set of cabin-level sprinkler components are provided in each energy storage cabin, a set of cluster-level sprinkler components are provided in each battery cluster, and a battery pack sprinkler is provided in each battery pack;

[0040] The other end of each cluster-level branch pipeline is also respectively connected with a plurality of battery-pack-level branch pipelines, and the plurality of battery-pack-level branch pipelines extend into a plurality of battery packs of the battery cluster one by one and are respectively connected with the battery-pack-level spray heads of the plurality of battery packs; a fifth control valve is connected between each battery-pack-level spray head and the corresponding battery-pack-level branch pipeline, and a sixth control valve is arranged between each battery-pack-level branch pipeline and the corresponding cluster-level branch pipeline;

[0042] When a fire occurs in a certain battery pack or there is a tendency of fire, the fire control host takes the battery pack as a local application unit and precisely directly acts perfluoromethylhexanone in the battery pack by controlling the corresponding valves to achieve the effect of precise fire extinguishing; if a fire occurs in a certain battery cluster or there is a tendency of fire, the fire control host controls to open the valve of the cluster-level branch pipeline corresponding to the cluster to simultaneously spray perfluoromethylhexanone fire extinguishing agent into all battery packs in the cluster, and at the same time, the inside of the box body of the cluster is fully flooded through the cluster-level spray head assembly, effectively ensuring the fire extinguishing effect on the battery cluster and avoiding affecting other battery clusters. Moreover, the perfluoromethylhexanone fire extinguishing mechanism and the liquid nitrogen explosion suppression mechanism in this embodiment share a set of pipeline mechanism, which can effectively reduce the structural complexity of the energy storage cabin while reducing costs.

[0043] Among them, Figure 1 the control valves include a first control valve, a second control valve, a third control valve, a fourth control valve, a fifth control valve and a sixth control valve.

[0044] Among them, the preset fire extinguishing strategy in this embodiment specifically includes:

[0045] The automatic fire extinguishing of the perfluoromethylhexanone fire extinguishing mechanism is in a delayed start state, and the delay time is 30 seconds. At the same time, the fire control host starts the audible and visual alarm to prompt personnel to evacuate;

[0046] When the perfluoromethylhexanone fire extinguishing system judges that the fire extinguishing agent has been sprayed out, the liquid nitrogen explosion suppression device is synchronously started to continue extinguishing the faulty unit;

[0047] Among them, when an alarm occurs in a certain battery pack / battery cluster / energy storage cabin and the perfluoromethylhexanone fire extinguishing device or the liquid nitrogen explosion suppression device needs to be started, first open the control valve corresponding to the cluster, and after a delay of 30S, the pump-type perfluoromethylhexanone host is started, and the atomizing spray heads of all battery modules in the battery cluster spray perfluoromethylhexanone fire extinguishing agent at the same time.

[0054] This embodiment also includes a camera mechanism and a remote fire control host. The camera mechanism is used to obtain the video of the energy storage station. When a fire warning of a corresponding level is received manually based on the video of the energy storage station or the remote fire control host, and it is manually determined that the firefighting has not been started, the fire extinguishing system of the corresponding cabin can be manually started remotely through the fire host in the fire control room. The firefighting logic is the same as the aforementioned automatic method.
