The rear door assembly 1C is connected to the right side plate at this location, and the gap formed between the door assembly and the right side plate is the sealing groove 115.

[0089] 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 to serve as the first waterproof structure.

[0090] In one implementation, 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 communicating 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 with the frame assembly 1B, and the sealing sleeve 118 is received in the step hole 120B.

[0091] Specifically, the fastener 117 may be a screw, and the sealing sleeve 118 may be a sealing rubber sleeve. The shell plates and reinforcing ribs of the rear door assembly 1C and the frame assembly 1B are provided with fixing holes 120A, and the fastener 117 passes through the fixing holes 120A to fix the rear door assembly 1C and the frame assembly 1B.

[0092] 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.

[0093] 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 on the frame assembly 1B. In this case, 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.

[0094] In one implementation, please refer to Figure 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.

[0095] Specifically, after the shell plate is wrapped around the other surface of the reinforcing rib, it can be bent toward the direction of 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 a baffle can be formed to block the water vapor passing through the sealing groove 115, thereby achieving secondary protection after the first sealing gasket 116A fails.

[0096] The second sealing gasket 116B is arranged between the hook flange 119 and the rear door. After the rear door assembly 1C and the reinforcement assembly are installed, the hook flange 119 is squeezed until the second sealing gasket 116B is tightly attached. The frame assembly 1B is designed with a hook flange structure. During the process of fastening the rear door panel, the hook flange is embedded in the second sealing structure to form a third waterproof structure, and the three-layer protection reaches the IP67 protection level.

[0097] In one implementation, please refer to Figure 1The top plate of the cabinet 1 is also designed with a sling 14, a fire air inlet 15 and a cabinet column 16. The fire air inlet 15 is connected to the external space and the second cavity 11C by opening and closing. The sling 14 is used for transportation and turnover. The fire air inlet 123 is designed on the top to meet the fire safety standards of the cabinet 1. The cabinet columns 16 are designed at the four corners of the top to be used for multiple cabinets 1 to be connected to each other to meet the seismic standards.

[0098] In one implementation, please refer to Figure 4 , an explosion-proof connection port 125 is also provided on the welding barrier of the partition plate assembly 12, and the explosion-proof connection port 125 is located at the upper end of the partition plate assembly 12, and can be arranged side by side with the air outlet. Among them, the air intake unit 7, the exhaust unit 8, the air intake port 123 and the air outlet together constitute an active exhaust structure, and the explosion-proof connection port 125 is installed with an explosion-proof pressure relief unit to constitute a passive exhaust structure. In this way, the active exhaust structure and the passive exhaust structure jointly meet the safety standards of the energy storage fire protection battery 2.

[0099] In one implementation, please refer to Figure 4 The welding partition of the partition plate assembly 12 is also provided with an auxiliary power supply connection port 126 and a communication connection port 127, wherein 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, and 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.

[0100] In one implementation, please refer to Figure 2 The battery 2 control unit is placed in the lower end area of ​​the first cavity 11B. One side of the battery 2 control unit is connected to the electrical connector on the first opening 121. The battery 2 control power supply is also connected to the auxiliary power supply connection port 126 and the communication connection port 127.
