[0020] The beneficial effects of the present invention are as follows: (1) The present invention is designed to cooperate with the automatic plug-in charging mechanism by designing a sealing protection mechanism. When waterlogging occurs in the basement, after both water level sensors sense that the water level has reached the set value, the information is transmitted to the display control component. The display control component then disconnects the power supply and controls the first drive motor, the second drive motor, the two third drive motors and the fourth motor to quickly reset the entire automatic plug-in charging mechanism.
