The invention belongs to the technical field of electric vehicles, and particularly relates to an underground parking lot electric vehicle charging pile waterproof device which comprises a charging pile. A charging port and a charging gun containing groove are formed in the side face of the charging pile. A pin shaft is fixedly connected between the inner walls of the two sides of the charging port, a charging port cover is rotationally connected to the pin shaft, and a sealing ring is fixedly connected to the charging port cover. A waterproof device is arranged in the charging pile, the waterproof device comprises a humidity sensor, and a cavity and an element cavity are formed in the charging pile. According to the underground parking lot electric vehicle charging pile waterproof device,through the arrangement of the waterproof device, when a lot of water is accumulated in an underground parking lot, the water will enter the charging pile, and when the water level in the cavity reaches a certain value, the humidity sensor enables a power source to be started, a miniature water suction pump discharges the water in the cavity, an electromagnetic reversing valve enables the water not to easily enter the cavity from a water drainage pipe of the miniature water suction pump, the water is automatically discharged, and the water is prevented from entering an element area of the charging pile.
本发明属于电动汽车技术领域,尤其是一种地下停车场电动汽车充电桩防水装置,包括充电桩,充电桩的侧面开设有充电口和充电枪放置槽,充电口的两侧内壁之间固定连接有销轴,销轴上转动连接有充电口盖,充电口盖上固定连接有密封圈,充电桩的内部设有防水装置,防水装置包括湿度传感器,充电桩的内部开设有空腔和元件腔。该地下停车场电动汽车充电桩防水装置,通过设置防水装置,当地下停车场内会积蓄较多的水时,水会进入充电桩内,空腔内的水位达到一定值时,湿度传感器会使得电源启动,微型抽水泵将空腔内的水排出,且电磁换向阀使得水不易从微型抽水泵的排水管进入空腔内,自动将水排出,避免水进入充电桩的元件区域内。
