[0025] The positions of the multiple groups of energy storage elements 9 and the multiple groups of sprinklers 66 are consistent.

[0026] Through the fire extinguishing mechanism 6, the dry powder tank 62 can extinguish the fire inside the energy storage cabinet 2, so that the fire extinguishing work can be quickly located to prevent the fire point from spreading and causing damage to other intact energy storage elements 9. Through the cooling mechanism 7, the condensed water in the condensed water tank 71 can be used to cool the energy storage elements 9 inside the energy storage cabinet 2, thereby preventing the internal temperature of the energy storage cabinet 2 from being too high and causing damage.

[0027] like Figure 3As shown, the fire extinguishing mechanism 6 includes a fire extinguishing box 61, the lower end of the fire extinguishing box 61 is fixedly connected to the upper left end of the base 1, a dry powder tank 62 is movably installed inside the fire extinguishing box 61, an electronic valve 63 is fixedly installed on the upper end of the fire extinguishing box 61, a connected conduit 64 is fixedly installed on the upper end of the electronic valve 63, a connected shunt pipe 65 is fixedly installed on the top of the conduit 64, and a plurality of groups of connected sprayers 66 are fixedly installed on the top of the shunt pipe 65.

[0028] The output port of the dry powder tank 62 is fixedly connected to the lower end of the electronic valve 63 and communicates with each other.

[0029] The top end of the shunt pipe 65 extends into the energy storage cabinet 2 .

[0030] After the fire is extinguished, the dry powder tank 62 can be removed and replaced separately from the fire extinguishing box 61, so that there is no need to disassemble and replace the entire mechanism, thereby greatly reducing costs.

[0031] like Figure 4 As shown, the cooling mechanism 7 includes a condensing water tank 71, the lower end of which is fixedly connected to the right rear side of the upper end of the base 1, a connected circulating pump 72 is fixedly installed on the top of the condensing water tank 71, a connected water inlet pipe 73 is fixedly installed on the upper end of the circulating pump 72, a circulating pipe 74 is installed on the inner rear side of the energy storage cabinet 2, a fixing ring 75 is sleeved on the outside of the circulating pipe 74, and a connected water outlet pipe 76 is fixedly installed on the lower left end of the condensing water tank 71.

[0036] like Figure 1-4As shown, when the self-cooling energy storage cabinet is in use, when the energy storage element 9 in the energy storage cabinet 2 catches fire, the smoke sensor on the bottom end of the partition 8 and the top end of the energy storage cabinet 2 senses it, and then the ignition point partition is quickly located according to the temperature in the partition and the concentration of the smoke, and then the electronic valve 63 is opened, so that the dry powder in the dry powder tank 62 enters the conduit 64 through the electronic valve 63, and then the corresponding sprayer 66 is opened, and then the dry powder in the conduit 64 enters the shunt pipe 65, and then enters the corresponding sprayer 66, and then the dry powder in the partition is sprayed by the sprayer 66. The energy storage element 9 is used for emergency fire extinguishing, thereby ensuring that other intact energy storage elements 9 can operate intactly, thereby improving the use effect of the energy storage cabinet 2; when the internal temperature of the energy storage cabinet 2 reaches the temperature set by the temperature sensor, the circulation pump 72 can be started, so that the circulation pump 72 can extract the condensed water in the condensed water tank 71 and transport it to the circulation pipe 74 through the water inlet pipe 73, and then the serpentine circulation pipe 74 can be used to take away part of the heat inside the energy storage cabinet 2, and at the same time, the circulation pipe 74 flows into the condensed water tank 71 again through the water outlet pipe 76 for cooling, so as to facilitate recycling.
