Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a fire protection system of an energy storage cabinet and the energy storage cabinet. Background Art

[0002] In the energy storage industry, battery energy storage cabinets are commonly used for energy storage. However, when the batteries in the cabinet convert input electrical energy into chemical energy, there is also a loss of electrical energy converted into heat energy. The heat energy emitted by the batteries will accumulate in the sealed cabinet body, causing the cabinet to continue to heat up.

[0003] Excessive heat accumulation or abnormalities in a confined space can easily lead to spontaneous combustion of batteries. Therefore, energy storage cabinets are often equipped with appropriate firefighting equipment. Existing energy storage cabinets typically only have one firefighting device, which is used to directly extinguish a fire in the battery compartment. However, if the fire inside the battery compartment is large, it can easily cause the outer surface of the battery compartment to catch fire. In this case, the firefighting equipment cannot effectively control the fire in the battery compartment, and it can easily spread to the surrounding area, causing casualties. Utility Model Content

[0031] Embodiment 1:

[0032] This embodiment provides a fire protection system for an energy storage cabinet. Referring to Figures 1 to 6 , it includes an energy storage cabinet body 1 and a detection mechanism, a first fire protection mechanism, and a second fire protection mechanism provided on the energy storage cabinet body 1. A plurality of battery boxes 11 are installed inside the energy storage cabinet body 1. The detection mechanism is used to detect the fire ignition state of the battery box 11. The first fire protection mechanism is used to spray a first fire extinguishing medium into the interior of the battery box 11. The second fire protection mechanism is used to spray a second fire extinguishing medium onto the outer surface of the battery box 11. When the detection mechanism detects that the battery inside the battery box 11 catches fire, it controls the first fire protection mechanism to spray the first fire extinguishing medium into the interior of the battery box 11. The first fire extinguishing medium can directly act on the fire source and can timely control the fire. When the fire is large and the first fire protection mechanism cannot effectively control the fire, the second fire protection mechanism is used to spray the second fire extinguishing medium onto the surface of the battery box 11 for auxiliary fire extinguishing. By combining the first fire protection mechanism and the second fire protection mechanism for fire extinguishing, the fire extinguishing efficiency can be significantly improved, ensuring the safe use of the energy storage cabinet.

[0033] Specifically, the first fire extinguishing mechanism includes a first fire extinguishing pipeline 32 for conveying a first fire extinguishing medium and a storage container 31 for storing the first fire extinguishing medium. The first fire extinguishing pipeline 32 is connected to the storage container 31, and at least one fire extinguishing pipe 33 is connected to the first fire extinguishing pipeline 32. One end of the fire extinguishing pipe 33 is connected to the first fire extinguishing pipeline 32, and the other end extends into the interior of the battery box 11. The number of fire extinguishing pipes 33 is set according to the number of battery boxes 11, that is, each battery box 11 is connected with a fire extinguishing pipe 33 to ensure effective fire extinguishing for each battery box 11.

[0034] Furthermore, one end of the fire extinguishing pipe 33 connected to the battery box 11 is provided with a first nozzle 34 and a control valve 35 for controlling the flow rate of the first nozzle 34. The control valve 35 is electrically connected to the control system of the first fire extinguishing mechanism. The output end of the first nozzle 34 communicates with the interior of the battery box 11. When the detection mechanism detects a fire inside the battery box 11, the first nozzle 34 can be opened through the control valve 35 for targeted fire extinguishing.

[0035] In this embodiment, the first fire extinguishing medium is set as perfluorohexanone reagent. Perfluorohexanone is easily vaporized at room temperature. During the vaporization process, it absorbs a large amount of heat, rapidly reducing the temperature around the fire source, and can effectively extinguish the fire in the battery box 11. At the same time, perfluorohexanone is an insulating medium, which can effectively isolate the connections between the batteries, that is, it will not damage the electrical equipment in the battery box 11.

[0036] In this embodiment, the second fire extinguishing mechanism includes a second fire extinguishing pipeline 41 provided at the top inside the energy storage cabinet 1 for transmitting a second fire extinguishing medium and a second nozzle 42 connected to the second fire extinguishing pipeline 41 for spraying the second fire extinguishing medium. At the same time, a connector 43 connected to the second fire extinguishing pipeline 41 is also provided on the outer surface of the energy storage cabinet 1. Through the connector 43, the second fire extinguishing medium can be conveyed from the outside into the second fire extinguishing pipeline 41. When it is necessary to use the second fire extinguishing mechanism for fire extinguishing, the operator can access the second fire extinguishing medium from the outside for fire extinguishing, so there is no need to store the second fire extinguishing medium inside the energy storage cabinet 1.

[0037] Preferably, the second fire extinguishing medium is water. Spraying water directly on the outer surface of the battery box 11 can effectively cool the battery box 11, assist the first fire extinguishing mechanism in extinguishing the fire in the battery box, and prevent the fire from getting out of control and spreading.

[0038] In addition, when the batteries inside the battery box 11 burn, flammable gases such as hydrogen or carbon monoxide are likely to be generated. When mixed with air, they are prone to explosion. Therefore, an exhaust mechanism 5 is provided on the energy storage cabinet body 1. The exhaust mechanism 5 includes a ventilation port 51 opened on the energy storage cabinet body 1 and an exhaust fan 52 arranged on the ventilation port 51 for exhausting the gas inside the energy storage cabinet body 1. When the battery box 11 inside the energy storage cabinet catches fire, the exhaust fan 52 can exhaust the flammable gas inside the energy storage cabinet body 1, thereby reducing the risk of explosion accidents.

[0039] In this embodiment, the detection mechanism includes a detector 21 and a monitor 22. The number of detectors 21 is multiple, and a detector 21 is installed corresponding to each battery box 11 to ensure accurate monitoring of the fire occurrence state inside each battery box 11. The detector 21 and the monitor 22 are electrically connected. The monitor 22 is used to receive the detection results of the detector 21 and can issue an alarm to remind the operator. The detector 21 used in this embodiment is preferably a composite detector, which can detect various fire indicators such as temperature, smoke, and gas, and has strong reliability.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
