Description

Technical Field

[0001] The utility model relates to the technical field of smoke alarm, and specifically, to a smoke sensor alarm device for charging piles. Background Art

[0002] Charging piles are also rapidly applied in each city. The function of a charging pile is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall, and can charge various models of electric vehicles according to different voltage levels. During the use of the charging pile, in order to prevent the wires from spontaneously igniting and causing a fire when the charging pile has faults such as short circuit, overload, and overvoltage, it is necessary to monitor the charging pile in real time. When a fire occurs due to a short circuit or the failure of internal components in the charging pile, an alarm is issued to remind and avoid greater losses. Currently, a smoke sensor is usually used to monitor the content of sulfurized foreign gas around the inside of the charging pile in real time to prevent fires. However, in the current technology, the smoke sensor is usually fixed to the charging pile with bolts. When the smoke sensor needs to be disassembled or installed, all bolts need to be disassembled or tightened, which is troublesome to operate and reduces the efficiency of the staff. In view of this, we have proposed a smoke sensor alarm device for charging piles. Content of the Utility Model
