Protection device for charging pile power supply

Abstract

The invention discloses a protection device for a charging pile power supply. The protection device comprises a fixed seat, a housing and a device body, wherein the housing and the device body are both in a cavity structure; the fixed seat is fixed on the bottom end of the housing; the device body is disposed in the housing; a ventilating port is formed in the top end of the housing; a top lid ishinged to the top end of the device body; a plurality of heat radiation holes arrayed in a straight way are formed on the tops of the two sides of the device body; heat radiation fans are mounted on the inner walls of the two sides of the device body; the heat radiation fans are corresponding to the heat radiation holes; two fixing blocks are arranged in the middle of the bottom end of the devicebody; the fixing blocks are arranged on two sides of the bottom of the device body; an elevating plate is horizontally connected between the two fixing blocks; and a vertically-arranged air cylinder is fixed in the middle of the top end of the fixed seat. The protection device is rationally designed and simple to operate, has obvious heat radiating effect, protect the power supply from damages, and can effectively prolong service life of the power supply.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a power protection device for charging piles. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The display scre...
