TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of charging equipment, in particular to a grounding protection assembly for a charging pile and a gas station charging equipment. BACKGROUND
[0002] The gas station charging equipment mainly refers to the equipment for providing electric energy supplement for new energy vehicles such as electric vehicles. With the rapid development of the electric vehicle industry, the charging equipment in the gas station becomes a key infrastructure. The charging equipment includes a plurality of charging piles arranged at intervals. Each charging pile needs to realize grounding. The grounding mode is generally that two ends of a grounding connecting piece are connected to a grounding terminal of the charging pile and a grounding device under the ground respectively, so as to ensure the safe operation of the charging pile and the personal safety of the user. Therefore, the stability of the grounding welding portion (i.e. the welding connection position of the grounding terminal of the charging pile and the grounding connecting piece) of the charging pile is crucial.
[0003] The charging pile is generally arranged in an outdoor open space. Due to long-term rain erosion, the grounding welding portion of the charging pile is easily corroded by rain. In the prior art, protective paint is generally coated on the surface of the grounding welding portion of the charging pile to avoid corrosion of the grounding welding portion by rain. However, the waterproof performance of the protective paint is poor. Under the long-term erosion of rain, the protective paint is easy to fall off, causing the grounding welding portion to age and corrode, resulting in a decrease in the connection strength of the grounding welding portion and the charging pile, and even causing the grounding welding portion to loosen or break, so that the charging pile loses grounding protection, thereby causing serious safety accidents.
