First of all, through the lifting mechanism design, it is not only convenient for the staff to lift the new energy charging pile to a height sufficient to meet the height of most urban waterlogging, but also to avoid damage or leakage of the new energy charging pile after being soaked in water. In addition, the relevant supporting electrical components are also located at high places to ensure safety and stability during use; secondly, in conjunction with the power disconnection blocking and sealing mechanism, the new energy charging pile can also be blocked and sealed after being disconnected from the existing line cable, ensuring that the exposed cable line is waterproof and sealed, avoiding the problem of leakage caused by exposed cables.
