Description

Technical Field

[0001] The utility model relates to a fireproof charging pile and belongs to the technical field of charging piles. Background Art

[0002] A charging pile is a device that replenishes electricity for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in public buildings and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] The existing patent announcement number is CN218750358U, which is a fireproof charging pile. In this device, the fireproof outer shell and the flame retardant sponge layer both have fireproof properties. The double-layer protective structure formed by the fireproof outer shell and the flame retardant sponge layer further improves the fireproof performance of the utility model. However, this device only uses a fireproof structure for fire protection, which is difficult to perform heat insulation treatment. In the case of an open flame, it is difficult to perform timely fire extinguishing and alarm treatment around the charging pile, which can easily cause the high temperature to continue to rise and cause damage to the internal components of the charging pile. Moreover, this device is arranged in an integrated manner, and is easily submerged in water during the rainy season when in use. Its waterproof performance is low, which affects the overall safety of the charging pile. Utility Model Content
