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 repla

Embodiment 1

[0051] A charging pile device, such as image 3 As shown, it includes a radiator 1, a heat dissipation fan 2 and a dust filter 3, and also includes a controller, a first collection unit, a second collection unit and a wind pressure detection tube; the first collection unit is arranged outside the charging pile housing, For real-time collection of ambient temperature and ambient humidity; the second collection unit is arranged on the radiator 1 for real-time collection of radiator temperature; the cooling fan 2 is arranged on the radiator 1 and the dust filter 3 Between them, it is used to dissipate the heat of the radiator 1 and remove the accumulated dust on the dust filter 3; pile dust, the dust removal filter screen 3 is provided with a vibration motor, and the vibration motor is connected to the power supply through the coil of the relay; The pressure on both sides respectively represents the external environment pressure value of the charging pile and the inner pressure ...

Embodiment 2

[0053] In order to realize the automatic dust removal method for the charging pile with the above dust removal device, as attached Figure 1-2 As shown, the automatic dust removal method of the charging pile includes the following steps:

[0054] S1, start charging, start the cooling fan, run the preset time N1, and enter S2;

[0055] Specifically, after the cooling fan 2 runs for a period of time, the operation of the charging pile enters a stable state, the temperature of the current radiator 1 is relatively stable, and the collected data is more reliable. In general, N1 can be 2 minutes to 5 minutes.

[0056] S201, real-time collection of ambient temperature, ambient humidity and radiator temperature;

[0057] Specifically, the first collection unit is set on the charging pile casing to collect the ambient temperature and humidity in real time. The ambient temperature and humidity have a certain influence on the heat dissipation rate. When the ambient temperature and the ...

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 ...
