[0008] A square shielding member is a member made of flexible plastic and is detachably provided on the edge of a square receiving groove; a hanging ring is provided on one side of the direction shielding member in the square receiving groove, and a hook is provided on the square receiving groove.

[0009] Furthermore, the square shielding piece is provided with a Velcro fleece surface, and the edge of the square receiving groove is provided with a Velcro thorn surface.

[0010] Furthermore, a heat dissipation device is provided in the charging pile body.

[0011] Furthermore, the alarm is a red flashing light.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] During actual use, when the leakage detection device detects leakage, the controller immediately cuts off the power supply and controls the alarm to remind the user that the charging pile has leakage. In addition, when the charging gun is not in use, place the charging gun in the square receiving slot and cover it with a square covering piece to protect it from damage by rain and sun.
