The position of the connecting ring 39 is fixed on the rotating shaft 11, so that the connecting ring 39 synchronously rotates along with the rotating shaft 11 to drive the transverse shaft 40 to rotate, the circular ring 41 is sleeved on the transverse shaft 40, the circular ring 41 is fixedly connected with the magnet 25 to drive the magnet 25 to rotate at a fixed height position, and the connecting ring 39 is arranged at the center position of the two iron plates 24, so that the magnet 25 and the iron plates 24 can be kept to rotate at the same height position.

Preferably, in order to prevent the iron plate 24 from rotating stably, a position limiting cover 44 is disposed on the outer periphery of the air inlet pipe 20, the position limiting cover 44 is fixed below the main body 2, and the iron plate 24 is located inside the position limiting cover 44. The end of the iron plate 24 far away from the air inlet pipe 20 can be supported by the limit cover 44, so that the iron plate 24 can rotate stably.

When the charging pile charges an automobile, the motor 16 drives the roller 17 to rotate, so that the sliding block 18 rotates in the annular groove 19, the telescopic unit supports the air distribution plate 10 to abut against the lower part of the base plate 9 to rotate, the rotating shaft 11 rotates to drive the first gear 12 to rotate, the first gear 12 drives the second gear 13 to rotate, the rotor 15 on the rotating rod 14 rotates to generate an airflow to flow upwards, outside air is sucked into the air inlet pipe 20 through the air inlet of the air inlet pipe 20, the filter screen 22 is used for dedusting and filtering the inlet air, the rotating shaft 11 drives the magnet 25 and the iron plate 24 to rotate, the magnet 25 attracts the iron plate 24 to be close to the air inlet pipe 20, dust and impurities on the filter screen 22 are swept by a brush, the circulation of the air is ensured, and after the air distribution plate 10 rotates, cold air entering the main body 2 is driven to flow upwards through the second through hole on the air distribution plate 10 and the first through hole, make cold air evenly distributed in main part 2, and hot-air is discharged from the gas vent, so, has realized the good heat dissipation cooling of equipment, and then has improved the practicality of equipment.

compared with the prior art, this electric pile that fills that the radiating effect is good can produce the air current through gas distribution mechanism, attract outside cold air to get into in the main part 2 through air inlet mechanism, and utilize pivoted gas distribution board 10 to make cold air pass through first through-hole evenly distributed on base plate 9 in main part 2, hot-air passes through the gas vent and discharges, and, when removing dust and filtering the outside air that gets into through air inlet mechanism, still can clean filter screen 22 automatically, guarantee the circulation of air, realize good radiating effect, the practicality of equipment has been improved.

in light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
