[0004] However, it has certain disadvantages: although its shielding component can prevent rainwater from entering the interior of the charging pile, it cannot prevent dust in the air from entering the interior of the charging pile through the ventilation holes, and therefore cannot prevent the influence of dust on the internal circuit of the charging pile.

The right end of the mounting block 13 is mounted on the left side surface of the charging pile body 1. A motor 14 is mounted on the rear surface of the lower mounting block 13. A first synchronous wheel 15 is mounted on the output end of the motor 14. The front surface of the upper mounting block 13 is rotatably connected with a second synchronous wheel 16. A synchronous belt 17 is mounted on the outside of the second synchronous wheel 16. The lower end of the synchronous belt 17 is mounted on the outside of the first synchronous wheel 15. A connecting block 18 is mounted on the outside of the synchronous belt 17. The interior of the connecting block 18 is located on one side of the synchronous belt 17 and is movably connected to two sliding rods 19.

The alarm signal of the sensor is transmitted to the charging pile main control board. After receiving the relevant signal, the charging pile main control board uploads it to the external main control platform and disconnects the main input circuit breaker. The external main control platform notifies the site staff to deal with it in time; it is used to quickly issue an alarm when water accumulates inside the charging pile body 1.
[0042] The working principle of the utility model is: when in use, the user removes the charging gun to charge the vehicle; when it rains, rainwater is blocked by the support box 7, preventing rainwater from entering the interior of the charging pile body 1 through the heat dissipation hole 2; at regular intervals, the motor 14 starts to drive the first synchronous wheel 15 to rotate, thereby driving the synchronous belt 17 to rotate, and then driving the connecting block 18 to rise and fall, so that the cleaning brush 20 cleans the filter plate 10, avoiding blockage and ensuring air circulation; when the surface of the charging pile body 1 is damaged, rainwater enters the interior of the charging pile body 1 through the damaged area, and when the accumulated water touches the water immersion sensor 21, the external main control platform receives a signal and immediately notifies the site staff to deal with it in time.
