Automatic dust removal method and device of charging pile

Abstract

The invention relates to an automatic dust removal method of a charging pile. Each time the charging pile is charged, the rotating speed of a heat dissipation fan is determined according to the ambient temperature and the ambient humidity of the charging pile and the temperature of a radiator, a preset pressure difference absolute value of the two sides of a dust removal filter screen is obtainedaccording to the rotating speed of the heat dissipation fan, the preset pressure difference absolute value is compared with an actual pressure difference absolute value to judge whether dust removal is needed, and if dust removal is needed, a vibration motor is started to vibrate the dust removal filter screen, dust on the dust removal filter screen falls down, the heat dissipation fan alternatelyruns at two speeds to enable the dust removal filter screen to have different tensions, the tension of the dust removal filter screen is instantly changed when the rotating speed is switched, dust attached to the dust removal filter screen can be shaken off, meanwhile, due to the rotation of the heat dissipation fan, air is blown to the outside of a charging pile shell, the dust attached to the dust removal filter screen is effectively removed, the dust removal filter screen of the charging pile is automatically kept clean, and air in the charging pile is purified. The service life of the charging pile is prolonged, and manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the field of charging piles, and specifically proposes an automatic dust removal method and device for charging piles. Background technique [0002] In recent years, with the popularization of the concept of green travel and the development of Internet technology, the electric vehicle industry has developed from initially satisfying basic driving functions to a new stage of pursuing informatization, intelligence, and networking. As an essential companion for electric vehicles, the importance of charging piles is self-evident. The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in the parking lot or charging station of public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. [0003] With the vigorous development of the new energy electric vehicle industry, the demand ...

AI Technical Summary

Problems solved by technology

Nowadays, many cities in China are seriously polluted, and there are many dust particles in the air. It is easy to enter the casing along the cooling port of the charging pile, which seriously affects the safety and service life of the charging pile.

[0004] In the field of dust removal for charging piles, the air inlet is basically used to set dust removal filters to absorb and remove the dust entering the charging piles. The dust removal filters need to be cleaned and replaced regularly, otherwise the dust removal function will be lost. Too much dust on the dust removal filter will also cause The heat emitted by the radiator is difficult to dissipate, which affects the heat dissipation effect and further affects the service life of the charging pile. In addition, some charging piles are installed far away from the urban area, which is particularly troublesome to maintain, wastes manpower and material resources, and has high maintenance costs.
