AI Technical Summary
The existing leakage detection device for charging pile verification is inconvenient to operate during use, especially traditional leakage detection requires operators to hold the measuring wires in one hand and pass the test pen to check with the other hand, which leads to inconvenient operation and inconvenient length adjustment, which makes it less practical.
A leakage detection device for charging pile verification is designed, including a leakage detector, a charging power socket and an annular shell. It is worn at the waist position of the pants through an elastic clamping frame, and the pen is separated from the arc-shaped positioning shrapnel. During detection, the connecting line body can be pulled from the annular shell, and the coil spring can tighten the connecting line and retract it into the annular shell, which is convenient for detecting leakage positions at different heights.
Convenient leakage detection operation is achieved, and operators do not need to manually adjust the length of the wire, and can flexibly detect leakage positions at different heights, which improves the convenience and practicality of detection. At the same time, by adding reinforcement ribs, the equipment's drop resistance and strength are enhanced.
