[0033] In this embodiment, the explosion-proof wall 1 includes a keel and an explosion-proof plate. The explosion-proof plate is fixedly connected to the cabinet frame through the keel. The specific connection method is welding. At the same time, the cabinet frame is formed by welding special steel bodies.

[0034] In the present embodiment, the explosion-proof plate comprises a double-layer explosion-proof steel plate 101, a fiber cement interlayer 102 is provided between the double-layer explosion-proof steel plate 101, and a plurality of pressure relief holes 103 are provided on the surface of the double-layer explosion-proof steel plate 101.

When an explosion occurs, the top thereof serves as the first pressure relief port. Secondly, at least two layers of explosion-proof plate provided around the temporary storage cabinet body 2 serve as the second pressure relief port. Furthermore, the configuration of the middle interlayer of the double-layer explosion-proof steel plate 101 provides a pressure relief effect. When an explosion occurs, the fiber cement interlayer 102 is squeezed out by the pressure relief holes 103, thereby avoiding the diffusion of debris to a certain extent.

[0037] In this embodiment, a video monitoring device 17 is further provided in the temporary storage cabinet body 2, and whether there is any abnormality inside can be directly observed through video monitoring.

[0038] In this embodiment, the fire extinguishing device 14 includes a fire extinguishing bottle filled with IG541 gas and a control valve. The control valve is electrically connected to the alarm host. The fire extinguishing gas is not limited to IG541 gas, and can also be other gases that can extinguish fires.

[0039] In this embodiment, a plurality of limiting mechanisms 18 are arranged in an array inside the temporary storage cabinet body 2. The limiting mechanism 18 includes a fixed plate 181 and a rubber shell 182 with an opening at the top. The rubber shell 182 is fixed on the top of the fixed plate 181. When multiple gas cylinders need to be placed, the gas cylinders are placed in the fixed plate through the rubber shell 182 to limit the gas cylinders in the fixed plate 181. The rubber shell 182 plays a role in increasing friction and stabilizing the gas cylinders. Figure 4 As shown, the fixing plate 181 is provided with a groove of a certain depth for the bottom of the gas cylinder to be placed.

[0040] In this embodiment, the limiting mechanism 18 further includes a partition plate 183 , which is disposed between two adjacent fixed plates 181 to prevent accidental tipping, and facilitates management through the partition plate 183 .

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
