In order to enhance the sealing performance of the second cavity 11C, a first sealing gasket 116A needs to be set in the sealing groove 115, and sealant can also be poured into the first sealing groove 115.

[0092] Optionally, the sealing groove 115 can be specifically formed by the shell plate and the rear door assembly 1C. The left and right sides of the cabinet body 1 can have a sealing groove 115, so the sealing groove 115 on the right side is used as an example. Based on the above embodiment, the frame assembly 1B includes a plurality of reinforcing ribs, one of which is located at one end of the right side panel near the rear door assembly 1C. The right side panel is connected to one surface of the reinforcing rib (the side of the reinforcing rib facing away from the left side panel) and also wraps around to and connects to another adjacent surface (the side of the reinforcing rib facing away from the partition panel assembly 12). The rear door assembly 1C is connected to the right side panel at this location, and the gap formed between the door assembly and the right side panel is the sealing groove 115.

[0093] Optionally, the rear door assembly 1C is installed on the frame assembly 1B to form a sealing groove 115 with the edge of the frame assembly 1B. The seam width of the sealing groove 115 is greater than or equal to 4 mm. Liquid or semi-solid sealant can also be injected into the sealing groove 115, which can serve as the first waterproof structure.

[0094] In one embodiment, please refer to Figures 7 to 9, the cabinet 1 includes a fastener 117 and a sealing sleeve 118, the rear door assembly 1C is provided with a connected step hole 120B and a fixing hole 120A, the fastener 117 passes through the step hole 120B and the fixing hole 120A to be connected to the frame assembly 1B, and the sealing sleeve 118 is accommodated in the step hole 120B.

[0095] Specifically, the fasteners 117 may be screws, and the sealing sleeves 118 may be rubber sealing sleeves. Fixing holes 120A are provided on the shell plates and reinforcement ribs of the rear door assembly 1C and the frame assembly 1B. The fasteners 117 pass through the fixing holes 120A to secure the rear door assembly 1C and the frame assembly 1B.

[0096] Optionally, a fixing hole 120A is opened on the reinforcing rib of the rear door assembly 1C, and a step hole 120B is opened on the back panel of the rear door assembly 1C; the step hole 120B and the fixing hole 120A are connected holes, and the aperture of the step hole 120B can be larger than the fixing hole 120A, so that the sealing sleeve 118 can be accommodated in the step hole 120B.

[0097] Optionally, the first sealing gasket 116A is designed to be perforated, and the fastener 117 passes through the fixing hole 120A to fix the rear door assembly 1C to the frame assembly 1B. At this time, the first sealing gasket 116A can serve as a second waterproof structure; at the same time, the rear door panel is designed with a step hole 120B, and the fastener 117 does not leak out at the step hole 120B. A sealing sleeve 118 is installed in the step hole 120B to prevent moisture from entering the interior of the frame assembly 1B through the fastener 117.

[0098] In one embodiment, referring to FIG. 7 , the frame assembly 1B includes a barbed flange 119 , and a spacing distance is provided between the barbed flange 119 and the rear door assembly 1C to form a sealing groove 115 , and a second sealing gasket 116B is provided between the barbed flange 119 and the rear door assembly 1C.

[0099] Specifically, after the shell plate wraps around the other side of the rib, it can be bent toward the rear door assembly 1C to form a barbed flange 119, so that the barbed flange 119 encloses the sealing groove 115. The advantage of forming the barbed flange 119 is that it can form a baffle to block water vapor passing through the sealing groove 115, thereby providing secondary protection after the first sealing gasket 116A mentioned above fails.

[0100] Secondary sealing gasket 116B is positioned between barbed flange 119 and the rear door. After rear door assembly 1C and the reinforcement assembly are installed, barbed flange 119 is squeezed against secondary sealing gasket 116B. The barbed flange design of frame assembly 1B allows the barbed flange to engage with the secondary sealing element during the tightening of the rear door panel, forming a third waterproof barrier. This triple layer of protection achieves IP67 protection.

[0101] In one embodiment, referring to Figure 1 , the top plate of the cabinet 1 is also designed with a sling 14, a fire air inlet 15, and a bridging column 16. The fire air inlet 15 opens and closes to connect the external space to the second cavity 11C. The sling 14 is used for transportation and hoisting. The fire air inlet 123 is designed on the top to meet the fire safety standards of the cabinet 1. Bridging columns 16 are designed at the four corners of the top to allow multiple cabinets 1 to be combined and meet seismic standards.

[0102] In one embodiment, referring to Figure 4 , the welded barrier layer of the partition plate assembly 12 is further provided with an explosion-proof connection port 125 . This connection port 125 is located at the upper end of the partition plate assembly 12 and can be positioned alongside the air outlet. The air intake unit 7 , the exhaust unit 8 , the air intake port 123 , and the air outlet together form an active exhaust structure, while the explosion-proof pressure relief unit mounted on the explosion-proof connection port 125 forms a passive exhaust structure. Together, these active and passive exhaust structures meet the safety standards of the energy storage fire protection battery 2 .

[0103] In one embodiment, referring to FIG4 , the welded barrier of the partition plate assembly 12 further includes an auxiliary power supply connection port 126 and a communication connection port 127 . The auxiliary power supply connection port 126 is located at the upper end of the partition plate assembly 12 and can be arranged side by side with the air outlet. The communication connection port 127 is located at the lower end of the partition plate assembly 12 . The design of the auxiliary power supply connection port 126 and the communication connection port 127 can meet the installation requirements of the signal line of the battery 2 in the second cavity 11C and the auxiliary power supply connector.

[0104] In one embodiment, please refer to Figure 2, the battery 2 control unit is placed in the lower end area of ​​the first cavity 11B, and the electrical connector on the first opening 121 of the unit on one side of the battery 2 control is connected. The battery 2 control power supply is also connected to the auxiliary power supply connection port 126 and the communication connection port 127. The other side of the battery 2 control is directly connected to the output port to connect to the outside world.

[0105] In one embodiment, as shown in FIG11 , the present disclosure further provides an electric device 10 , including an electric device 30 and an energy storage device 20 , wherein the energy storage device 20 supplies power to the electric device 30 .
