Abstract

The invention, which relates to the technical field of the charging pile, discloses an accumulated water self-cut-off air switch comprising a box body, an anti-immersion self-cut-off assembly, and a self-floating cut-off lock assembly. A power connection space and a connection column are arranged in the box body. The anti-immersion self-breaking assembly is in butt joint with the connecting column in a telescopic mode, meanwhile, resetting of a lock head of the anti-immersion self-breaking assembly is limited through a movable head on the self-floating breaking lock assembly, and therefore when no water is accumulated, the anti-immersion self-breaking assembly and the connecting column are normally powered on, and power is supplied to the charging pile. And when water is accumulated, a floating bag of the self-floating breaking lock assembly promotes a movable head to move upwards to be separated from a lock head on the sliding barrel under the floating action of the accumulated water, so that the anti-immersion self-breaking assembly is reset under the action of a reset spring, the anti-immersion self-breaking assembly is separated from the connecting column, and automatic power off can be achieved in time. The problem that the charging pile leaks electricity and hurts people due to the fact that the switch is soaked in water because the charging pile is faced with water and cannot cut off a power supply in time is solved.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a self-cutting air switch for accumulated water. Background technique [0002] In recent years, my country has vigorously supported the development of the electric vehicle industry and the construction of charging infrastructure. The number of electric vehicles and charging infrastructure has grown rapidly. By 2020, my country will add more than 4.8 million decentralized charging piles to meet the national demand for 5 million electric vehicles. charging needs. [0003] With the continuous popularization and development of electric vehicles, the construction of charging infrastructure is imminent. The establishment of charging piles has the characteristics of many distribution points and wide dispersion. However, various safety issues need to be considered in the actual use process. Rainfall in southern my country The charging piles set up often face the problem of flooding...
